Addiction, Passion, or Confusion? New Theoretical Insights on Exercise Addiction Research From the Case Study of a Female Body Builder

Exercise addiction is widely studied in sport science and psychology, but at this time it is not recognized as an independently diagnosable mental or psychiatric disorder. Indeed, studies on exercise addiction assess a level of risk for disordered exercise behaviour, characterized by lack of control and negative personal consequences. It is argued that commitment and passion are two overlapping features of high exercise involvement which obscure the fine line between healthy and unhealthy exercise. The present case study examined a successful female body builder who initially claimed that she was addicted to exercise. During an interview she also completed three questionnaires and her appraisal of well-being in eight life domains were assessed at present, as well as retrospectively before her intensive involvement with exercise. She was screened under the Non-Substance Related Disorders category of Substance-Related and Addictive Disorders classification of DSM-5 for gambling, by replacing the word "gambling" with "exercise". Although she was susceptible to exercise addiction, attained high scores on obsessive passion, exhibited more than four symptoms on the DSM list, she exhibited no signs of loss of control and she mainly reported positive experiences associated with her exercise behaviour. She has obtained a nearly maximum score on commitment to exercise and high score on harmonious passion. Almost all aspects of her life have changed in positive direction after getting intensely involved in exercise. This case illustrates that the current scholastic path to the study of exercise addiction may be obscured by ambiguous assumptions and unilateral quantitative focus.


A Gap in the Exercise Addiction Literature
A major dilemma in the current literature is whether exercise addiction occurs only among recreational exercisers or professional athletes as well. Since behavioural addictions, in general, reflect an escape from a psychological problem (Griffiths, 1996), some authors argue that athletes are unlikely to escape into an activity that dominates their daily lives . Also, the characteristics of exercise addiction in light of the interactional model (Egorov & Szabo, 2013) distinguishes therapeutically oriented exercise from that performed for mastery reasons. Finally, the unusually high scores reported by athletes on various exercise addiction scales prompted scholars to suspect that high athletic commitment may be confounded with exercise addiction . One approach to elucidate the problem is to use interviews with athletes thinking or claiming to be addicted to exercise and/or scoring high on exercise addiction measures .
This method could answer the question whether the interviewed (suspect to the disorder) athlete exhibits a dysfunction associated with specific patterns and high volumes of exercise or simply misinterprets the notion of addiction in relation to sport.

Prevalence of the Risk for Exercise Addiction
The prevalence of the risk for exercise addiction is relatively rare, ranging from 0.3% to 0.5% as revealed in a representative sample from the general population (Mónok et al., 2012). However, in specific samples higher rates were found. In five studies with university students, Hausenblas and Downs (2002) reported prevalence rates ranging between 3.4% and 13.4%. Griffiths, Szabo, and Terry (2005) fund that 3.0% of university students were at risk of exercise addiction, but in a later work the rate emerged to be higher (6.9%) among sport science students (Szabo & Griffiths, 2007). Further, another study that surveyed 95 ultra-marathoners found only three people (3.2%) at-risk for exercise addiction (Allegre, Therme, & Griffiths, 2007). However, higher figures were reported for university athletes (7%-10%) and even higher for ultra-marathon runners (17%; Szabo, De La Vega, Ruiz-Barquín, & Rivera, 2013a). It should be emphasized that the reported figures were derived from questionnaires which only measure the presumed risk for exercise addiction and, therefore, cannot be considered as diagnostic tools (Szabo, 2010).

Passion in Sport and Exercise
Heavy athletic involvement in sport is associated with passion (Vallerand et al., 2006). Passion seems to explain the exaggerated time devoted to sports or exercise, which is a common feature of athletic training and exercise addiction. Recently, based on a strong link established between exercise addiction and passion, it was suggested that "The concept of exercise addiction is not a plain and independent construct and may not reflect a psychological dysfunction in the athletic population" (De La Vega, Parastatidou, Ruíz-Barquín, & Szabo, 2016, p. 325). There is a dual model for passion comprised by obsessive and harmonious passion (Vallerand et al., 2003). As we have described in a recent study (Kovacsik et al., 2018), obsessive passion surfaces when the individual internalizes an activity in a controlled way and involvement is rigidly controlled; it is positively related to negative affect (Stenseng et al., 2011;Vallerand et al., 2003;Vallerand & Miquelon, 2007). The obsessively passionate person attaches great importance to activity contingencies, such as self-esteem and escape from problems which makes it hard for them to stop the passionate activity (Vallerand, 2010). Harmonious passion emerges when an activity is internalized autonomously and the individual engages in the activity with flexibility; it is associated with positive affect and it is inversely related to negative affect (Stenseng, Rise, & Kraft, 2011;Vallerand et al., 2003;Vallerand et al., 2006;Vallerand & Miquelon, 2007).

Exercise Addiction and Passion: New Research Findings
Few empirical studies have examined the relationship between exercise addiction and passion. Obsessive passion was positively associated with exercise addiction in endurance sports as well as other leisure physical activities (Schipfer & Stoll, 2015;Stenseng et al., 2011). It was shown that obsessive passion is associated with all the dimensions of exercise addiction, including time, reduction in other activities, tolerance, withdrawal, continuance, intention effects, and absence of control. This link was not demonstrated for harmonious passion which was only related to time and tolerance (Paradis, Cooke, Martin, & Hall, 2013). Further, it was shown that harmoniously passionate exercisers can increase their exercise volume without neglecting life responsibilities.
This is not the case for the obsessively passionate exercisers who spend exaggerated amounts of time on exercise while neglecting important responsibilities (Paradis et al., 2013). These findings are supported by a Greek research showing that obsessive passion has a stronger link to exercise addiction than harmonious passion (Parastatidou, Doganis, Theodorakis, & Vlachopoulos, 2014), and a Swedish study demonstrating that those at risk for exercise addiction also score higher on obsessive passion than those who are not at risk (Back, 2016).
The link between exercise addiction and passion, as a function of the athletic level of competition, was examined in a recent work studying a large sample of low-and high-level competitive athletes, and noncompetitive leisure exercisers (De La Vega et al., 2016). In line with Parastatidou et al. (2014), the findings revealed that, by accounting for 37% of the total variance, obsessive passion was a predictor of exercise addiction while harmonious passion was not. These findings may not be surprising in the view of the controlling and being controlled aspects of passion and addiction, nor considering negative and positive reinforcement that could be related to the emergence and persistence of harmonious and obsessive passion.
With the recent evidence showing that passion may influence the measures of exercise addiction, in a similar manner as commitment to exercise does, the re-evaluation of the approach to the study of exercise addiction may be necessary. It is accepted that the common denominator between the healthy skill-oriented athletic training and the unhealthy escape into exercise is the unusually great time devoted to workouts . Therefore, it is important to understand how a competing athlete feels about her/his exercise behaviour when she presents signs of exercise addictions on the bases of the current conceptualizations of the dysfunction.

Method The Research Method
As predicted by the interactional model, which states that personal predispositions, exercise experience, and life stress interact in the aetiology of exercise addiction (Egorov & Szabo, 2013), the studied dysfunction is highly idiosyncratic. Whether a person is affected by exercise addiction can only be established by using a personal interview that considers the antecedents, current situations, training habits, and subjective psychological outcomes . Indeed, questionnaires used in nomothetic research could only establish a "level of risk", but cannot clearly identify those who are affected by exercise addiction. Nevertheless, the inclusion of the usually adopted nomothetic measures might yield additional information to the qualitative data and reflect the match or the mismatch between the two. Therefore, as part of the interview the participant was also asked to rate the commonly accepted measures of exercise addiction. Her well-being was evaluated based on Swarbrick's (2006) eight life domains.

The Participant
After a campus-wide search for participants in an interview -listing the conditions for participation that included the typical symptoms of exercise addiction (Griffiths, 2005)  Evelyn. At the time of the interview, she was a 24-year-old university graduated woman who lived in Budapest, Hungary. She worked in a managerial-assistant position, which was important to her. During her university studies she attended a gym relatively sporadically, but gradually she got increasingly involved in body building.
After experiencing subjective and objective results, less than a year before the current interview, she has started to compete under the guidance of a coach and took part in two national and a major international competition. Thus, a shift from exercise to sport, or from an exerciser-to the athletic status, took place within the year of the current interview. Her early athletic results were very good considering her brief sporting history; she may be regarded as a highly successful athlete who has achieved three remarkable competition results within six months. She trained at least five times a week, for at least one and a half hour each time.
Occasionally, Evelyn felt like working out in addition to her scheduled training. The reason for the extra workouts was guilt for not having enough training or missing a training session, as well as lack of personal satisfaction with the planned progress or the self-set goals. She received notable support, but also criticism, from friends on social media in context of her sport and her athletic physical appearance. This change in her appearance, however, was perceived positively by Evelyn. She had little time for socialization due to her work and training. The lack of a fulfilling social life appeared to be the greatest concern at the time of the study.

Instruments: Measurements Complementing the Interview
It should be emphasized that this is not a nomothetic or quantitative study. It is a case study. Therefore, the tools used to complement the interview, while gathering numerical scores, should be still interpreted in a merely Untangling Passion From Addiction 300 qualitative manner, such as low, medium, or high (like the needle of the odometer) within a given range. These tools were adopted to assess the concordance between interview data and the relative (i.e. high-low) scoring on the commonly used measures in exercise addiction research. For example, if the participant would claim that she is highly addicted to exercise, but would score on the lower end of the Exercise Addiction Inventory, her answers would be questionable.
The six-item Exercise Addiction Inventory (EAI; Terry, Szabo, & Griffiths, 2004) was used to assess her risk for exercise addiction. Items of the EAI include statements like: "Exercise is the most important thing in my life." or " If I have to miss an exercise session I feel moody and irritable.". These statements are rated on a 5-point Likert scale, ranging from 'strongly disagree' to 'strongly agree'. The maximum score is 30. A score of 24 or over suggest high risk for exercise addiction. The scales' internal reliability (Cronbach α) ranges between .61 to .80 in several cross-cultural samples Mónok et al., 2012;Terry et al., 2004). The concurrent validity of the EAI, established through correlations with the Obligatory Exercise Questionnaire (Pasman & Thompson, 1988) and the Exercise Dependence Scale (Hausenblas & Downs, 2002), was .80 and .81, respectively. Its two-week test-retest reliability was .85 .
Passion was assessed using the revised Passion Scale ( The 9-item Deprivation Sensations Scale (Robbins & Joseph, 1985) was used to measure nine symptom of exercise withdrawal, such as irritability or frustration, rated on a 7-point Likert Scale. The scales' internal reliability is .81 (Szabo, Frenkl, & Caputo, 1996). There are no reports about other psychometric properties of the scale. Finally, nine symptoms-based Non-Substance Related Disorders category of Substance-Related and Addictive Disorders classification of DSM-5 for gambling (American Psychiatric Association, 2013) was used by replacing 'gambling' with the word 'exercise'. These were built into the interview since the mere presence or absence of a symptom was the point, while the rest were presented in scalar-form using paper and pencil tools.
(This is not a questionnaire, so no psychometric properties should be reported for the nine distinct categories, which was another reason for not presenting it as a paper and pencil instrument.)

Procedure: The Interview
The interview took place in a quiet place without distraction and lasted approximately one hour. Evelyn completed the questionnaires and subsequently answered questions in the context of her training and Szabo 301 emotional aspects of her sport. She then described and compared eight domains (Swarbrick, 2006) of her current well-being with the period preceding her intense involvement with body building. While, the author of this case study was (is) aware that retrospective answers could be biased, her subjective perception of the change (or difference) in the two situations was the most important. With Evelyn's consent the interview was recorded with a Smartphone's sound recorder application. The participant has approved the here published version of the interview.

Quantitative Measures
On the EAI, Evelyn scored 20 out of 30 of the maximum score, which classifies her as 'symptomatic' based on the criteria of interpretation recommended by Terry et al. (2004), but not 'at risk' for exercise addiction for which the cut-off point is 24. Her mean EAI value was 3.33, which is like the mean score (3.15) of 384 regularly exercising university students (Sicilia, Alcaraz-Ibáñez, Lirola, & Burgueño, 2017) and 78 Spanish women athletes (mean score 3.04; Szabo et al., 2013a). On the Passion Scale she scored 33 out of the maximum of 42 on the harmonious passion, yielding a mean of 5.50, which is comparable, but slightly lower than the mean value (6.22) recently reported for exercising university students (Sicilia et al., 2017), however it matches closely the mean values (5.00, 5.56 and 5.84) reported in three studies with recreational and competitive athletes by Vallerand et al. (2006). Evelyn scored 40 out of 42 on obsessive passion. This score yields a mean value of 6.67 that is higher than the mean values (3.07, 3.84, and 4.34) reported by Vallerand et al. (2006), or the mean value (4.83) found in a recent Spanish work (Sicilia et al., 2017). Further, on the affinity or commitment items she scored 33 out of the possible 35 points, which obviously is near the maximum possible, so clearly it indicates a high score. On the Deprivation Sensation Scale Evelyn scored 44 out of 63 possible, which is higher than the values reported for exercisers in five different forms of exercise ranging from 19/63 in bowlers to 34/63 in aerobic exercisers, with a score of 30/63 (gender not reported) for eight body builders (Szabo et al., 1996).
Her scores cannot be interpreted by considering the scores of other female body builders, because no such reports exist in the literature. Finally, she reported 6 out of 9 symptoms on the Non-Substance Related Disorders category of the DSM-5, that would classify her with disordered exercise behaviour (as an analogy to gambling disorder in the DSM-5). Her relative scores, in terms of percentages of the maximum (simply to illustrate the relative position [i.e., low, medium, high] of her answers), are summarized in Figure 1.
Untangling Passion From Addiction 302

Qualitative Measures Training
Evelyn's training is scheduled. She trains in a team with 30 other women in which every person gets limited personal attention from the coach. She is not happy about that, but since the training routines are identical, Evelyn feels that she can manage her own training. The athletes are on a strict personalized diet designed, but not provided, by the coach. Evelyn does not take performance or growth stimulating agents. She is not keen about the strict diet that she must follow, in fact she considers it as the most inconvenient aspect of her training regimen. Otherwise, Evelyn shows no signs of any eating-related problems. She usually has two rest days a week, but sometimes -once biweekly -it happens that she feels the need to exercise in addition to her scheduled training. This happens when she misses a workout or does not attain a set goal in time. While she reports no major injuries due to her exercise, she has some backache that she manages with waist support and lower-weight use in some exercise routines. She claims that working out helps her in dealing with life stress. Evelyn believes that she has experienced some losses due to her intense involvement in exercise primarily in her social life and personal relationships, as well as in her study progress during the last term of her university studies. She has experienced conflicts at work due to exercise. Her major aspiration is to perform better in competitions and to get sponsors for her sport, so she can spend more time with the sport and have a more stable financial outlook. In fact, she would like to blend her sport into a career.
Matching the components model for addiction (Griffiths, 2005), Evelyn admits that her training represents the highest priority in her life. She is also aware of the distressing withdrawal symptoms if training is not possible for a reason. She often uses exercise for mood alteration, especially in dealing with stress. While, she thinks that she had no major interpersonal conflict because of her exercise, some conflict has occurred at her workplace. Two components that were rated low on the EAI could not be detected during the interview either.
These were tolerance and relapse; she did not increase her amount of training in the past few months and she had no intention to stop or reduce her training.

Life Domains
The interview was centred around well-being in eight life domains: health (physical), environment, intellectual growth, occupation, health (emotional), social life, financial status, and spiritual life (Swarbrick, 2006). Initially she had to consider the momentary aspect of well-being in these domains and then she had to recall her wellbeing in these life domains before her intense involvement in body building (i.e., performing it as a sport and competing in it). The outcome measure was the perceived difference between her past and present, recorded as positive change, no change, or negative change. As illustrated in Table 1, Evelyn perceives her well-being better in six out of eight life domains at present in contrast to the past when exercise was not as important as today. The fact that work and exercise take a tool on her social life is manifested as a partially negative change compared to the past, while no major change could be detected in her spiritual life. This trend of improvement after her intense involvement in exercise is also justified by her answer to a sort of summary question asking her to show on a ruler where is her overall well-being now and where was it before her dedication to body building; the current rating corresponded to a 7-8 on 10 partition while the rating of her past well-being was only between 3-4. Clearly, if one considers the middle point (5) as the separation between negative and positive appraisal, it might be assumed that the intensified involvement in sport triggered positive changes in Evelyn's well-being. Note. Currently perceived well-being in eight life domains (Swarbrick, 2006) as compared to the recalled well-being before Evelyn's intense involvement in body building. The latter is also a current appreciation of past events; Therefore, the important outcome measure is the current state of the mind or thought. In bold fonts are the areas perceived as negative by Evelyn.

Discussion
Considering her quantitative responses, Evelyn could be classified as symptomatic based on the EAI and on the DSM-5 classification, as extrapolated from gambling to exercise, she would be diagnosed with disordered exercise behaviour. The diagnosis would be justified by the nearly maximum score on obsessive passion (refer to Figure 1). However, her data on deprivation sensations are far from the maximum, she scored relatively high on harmonious passion and reported nearly maximum scores on commitment to exercise. At first glance, these figures appear to be controversial, but they are not as it should become clear after a deeper evaluation.

Exercise Addiction Inventory (EAI): The Scoring Compared With the Interview
The EAI was built upon six symptoms commonly observed in all addictive behaviours (Terry et al., 2004).
Salience, or high priority and preoccupation with exercise is the first of the six symptoms. Evelyn scored five, which is the maximum when completing the scale and she also reaffirmed during the interview that basically her life revolves around her sport. On "withdrawal symptoms" again she gave a maximum rating and during the interview she confirmed the ever presence of these symptoms and even listed some of its forms, which were guilt, insomnia, and nervousness. However, on the Deprivation Sensation Scale, Evelyn scored 44 out of 63 possible, which is just slightly over than two thirds maximal score, yet it is higher than that reported earlier (30) for body builders (Szabo et al., 1996). This issue will be treated separately below, not only because of an apparent discrepancy between the EAI score plus interview and the Deprivation Sensation Scale results, but also because early research relied solely on the presence of withdrawal symptoms in establishing the existence of exercise addiction (Szabo, Griffiths, & Demetrovics, 2016). Evelyn scored four, representing agreement, on the "mood modification" item of the EAI and she justified her answer by stating that she often uses exercise in dealing with life-stress. On "conflict" her scale and interview scores were dissonant, because on the former she gave a score of two, reflecting the rather disagree answer, but during the interview she claimed that she has experienced some conflict at work. This discrepancy was followed up during the interview and it turned out that when she was rating the questionnaire she focused on her close relationships only. On the final two symptoms gauging "tolerance" (rated as 1, which means strongly disagree) and on "relapse" (rated as 3, meaning neither agrees nor disagrees) the scale results were consistent with the interview. When these questions were further probed during the interview, Evelyn explained that she has a stable training plan for a while that needs no adjustment in volume. Concerning relapse, she explained her rating through the fact that since she became heavily involved in her sport, she never tried to cut down the amount of training that she performs, so she has perceived this item as not applicable to her sport and thus could neither agree or disagree.
The study shows that in the current case study the quantitative assessment of the EAI was mostly in accord with the responses gained during the interview. However, the misinterpretation of the conflict item led to a lower score on the EAI. Nevertheless, even if she would have scored 5 (maximum) on this item, she would have had a total score of 23 that is still not reaching the cut-off score of 24, which draws the line between symptomatic and at-risk exercise behaviour (Terry et al., 2004). Thus, according to the EAI score, Evelyn could be classified as symptomatic, but the EAI items (which reflect the common symptoms of addictions based on the Components Model [Griffiths, 2005]) have a justifiably different interpretation in Evelyn' and perhaps other athletes' cases . Indeed, salience is an expectable characteristic of the athletes trying to get higher on the competition ladder. Withdrawal symptoms are "normal reactions" to all activities that one adopts as a part of the daily life; in fact, bowlers also have experienced deprivation feelings at the times when they Szabo 305 could not bowl, even though their symptoms were milder than those reported by body builders (Szabo et al., 1996). Conflict has the lowest factor loading on the EAI (Lichtenstein, Christiansen, Bilenberg, & Støving, 2014), but its presence is also "normal" in the highly committed athletes' life, because the training demands and associated obligations could result in interpersonal conflict . The item "mood modification" in Evelyn's case (as complemented by the interview) reflects her coping with life stress. While this item could be related to good performance, appearance, and exercise-induced feeling states in Evelyn's case it emerges as a coincidental coping mechanism. I stress the term "coincidental", because her motive for participation in sport is not to cope with stress per se, but to develop into a successful athlete. At the same time, she realizes that sport helps her in dealing with stress and she simply profits from the opportunity. While tolerance and relapse also have different meaning for exercise addicts and elite competing athletes , these symptoms were not relevant in Evelyn's case. Summing up the EAI-based findings for Evelyn, the paper and pencil tool emerged to be in accord with the interview except for one item.

Making Sense of the Withdrawal Symptoms
Evelyn scored the maximum (5) on the EAI withdrawal symptoms item and during the interview she also admitted experiencing unpleasant symptoms for the times when training is not possible. However, she only scored 69.8% of the maximum score on the Deprivation Sensations Scale. The slightly confounding results may be blamed on the tool's or response's reliability; but that would be a hazardous option. The fact is that the EAI is an agreement-disagreement scale on which the maximum score reflects a total agreement with the statement (i.e., that the respondent experiences withdrawal symptoms when exercise is not possible). This rating was corroborated by her responses during the interview. So why does it appear to be in discord with the deprivation score obtained on the Deprivation Sensation Scale? The answer is that the latter is a frequency scale on which the frequency of experiencing the symptoms yields a measure of the severity of the deprivation feelings. For example, if all symptoms are always present then they are quite severe compared to when only 5 out of 9 are being present with moderate frequency. Now this point may seem farfetched, but it is an important point that is being overlooked in the extant literature. As Szabo et al. (2016) have clarified, the mere presence of withdrawal symptoms is not indicative of exercise addiction, but their severity might be ( Figure 2). In Evelyn's case the actual presence of the withdrawal symptoms for the times when she must miss a training session were confirmed, but they were not maximal in severity (refer to Figure 2), which explains the discord between the results of the EAI, backed up with the interview, and her ratings of the deprivation sensations.
Untangling Passion From Addiction 306

Obsessive Passion and Harmonious Passion
Evelyn scored a close to maximum score on obsessive passion (refer to Figure 1). Given the reported relationship between exercise addiction and obsessive passion (De La Vega et al., 2016;Schipfer & Stoll, 2015;Stenseng et al., 2011), her score may be an index of maladaptive, controlled exercise, characterized by a rigid involvement (Stenseng et al., 2011;Vallerand et al., 2003;Vallerand & Miquelon, 2007). However, competitive athletes seem to score higher on obsessive passion as well as harmonious passion than recreational exercisers (De La Vega et al., 2016). Evelyn's score on harmonious passion was lower (33) than on obsessive passion (40), but it was higher than the mean score of the recreational exercisers (29.1) in De La Vega et al.'s. (2016) study, while it was fitting the mean values reported for competitive athletes (33.3 -33.9) in that work. These results make sense if one thinks about the controlling and rigid aspects of competitive sports; these characteristics stem from the discipline to follow a strict and demanding training regimen that, for the sake of success, virtually controls the athletes' lives. The high harmonious passion reflects the autonomously internalized activity, pride in success, and the joy of increasingly better performance. Thus, competitive athletes could be expected to exhibit high scores on both obsessive-and harmonious passion, one reflecting a surrender to conformity (e.g., "I must do it to ..., I must do an extra session to..., Unless I push myself, I will not...", and so on). These self-and coach-imposed pressures are not mere choices, but perceived obligations to which the athlete needs to succumb to succeed. They are controlled internalizations that could stem from both intra-and interpersonal pressures (Vallerand, 2012). Evelyn justified the cases of the extra training sessions with feelings of guilt when she missed a training session and with perceived lack of achieving her goals in time, or a sort of dissatisfaction with her progress, which mirrors her intrapersonal pressure.
On the other hand, high levels of harmonious passion reflect the chosen aspects related to sport behaviour.
They could involve the dedication, aspiration, and strong commitment mediated through the positive reinforcement of the regular training, stemming from an internal motivation i . However, it is more than internal Szabo 307 motivation, because the dedicated athlete identifies herself with what she is doing (Vallerand, 2012), that is part of her identity. The greater this part is, the higher the passion scores will be; obsessive passion surfaces with conformity and self-imposed pressure to achieve her goal, while harmonious passion rises with pride, enjoyment, and satisfaction. Her scores on these scales (Figure 3), in accord with De La Vega et al. 's. (2016) findings, support the conjecture that there is a two-dimensional nature of passion in sport.

Non-Substance Related Disorders Category of the DSM-5
Evelyn scored six out of nine of the symptoms enlisted for exercise disorder under the Non-Substance Related Disorders category of the DSM-5; scoring four or more on this category is an index of disordered behaviour (American Psychiatric Association, 2013). While adopting the symptoms of gambling disorder to exercise addiction could be criticized, there appears to be a valid ground for the practice (Potenza, 2014). The Exercise Dependence Scale (EDS; Hausenblas & Downs, 2002) was conceptualized based on the DSM-4 criteria for substance dependence. The problem is not with the drawn analogy between the two behavioural addictions, because analogy also exists between behavioural-and substance-related addictions (Alavi et al., 2012), but with the interpretation of these symptoms by elite athletes when they are presented for the evaluation of their training (see Table 2). Evelyn only denied three out of the nine DSM criteria: a) Item 3: trying to cut down on exercise; b) Item 7: lying about her exercise; and c) Item 9: relying on others to do things for her. All the other six criteria can be interpreted as part of who she is, or being an elite athlete. They are no longer pathological symptoms, but normal aspects of her training, whereas for a recreational exerciser may not be as "normal".
Indeed, Evelyn thought that those criteria suited her exercise behaviour. Examining the right column in Table 2, perhaps most readers would agree that those criteria, which could be symptoms for recreational exercisers, are natural aspects of the elite athletes' lives. Same with the EAI, which was developed with recreational Untangling Passion From Addiction 308 exercisers, athletes usually show very high scores because the items have a different meaning to them . Therefore, a great deal of confusion exists in the literature, unless high level of athletic involvement is paired with psychopathology. Indeed, Evelyn's appraisal of the DSM-5 criteria reflect the subjective appraisal of her athletic life as a successful body builder who longs for much more, and clearly does not reflect any sort of maladjustment. addiction (Szabo, 2010). A high score of commitment reflects how hard a person wants to achieve a goal and the extent to which she is willing to make sacrifices (Locke, 1996). High level of commitment cannot be separated from obsessive passion, which embodies the internal pressure to do something, or to engage in an activity (Forest, Mageau, Sarrazin, & Morin, 2011). Evelyn's high scores on both commitment to exercise and obsessive passion may appear controversial at the first glance, but they are not, since a nearly maximal score of commitment reflects one's willingness to push herself to the extremes, and thus apply strong internal pressure in working towards a desired goal.

Well-Being in Eight Life Domains Now and Before the Transition From Exercise to Sport
Out of the eight life domains of well-being (Swarbrick, 2006), Evelyn reported noticing improvements on six.  Schreiber & Hausenblas, 2015). While these results suggest that Evelyn feels much better in most life domains today than in the past, it should be appreciated that the latter appraisal of the events may be subject to memory distortion.

Synopsis
While many people like Evelyn may claim that they are addicted to exercise (Szabo, 2010), they refer to their high commitment to training. The latter, as noted in Evelyn's case, is paired with high obsessive-and harmonious passion, one reflecting the self-imposed pressure while the other the benefits of training.
Therefore, in accord with Evelyn's results, it is fair to anticipate high obsessive-and harmonious passion coupled with high level of commitment in successful athletes. Together, they are healthy adaptations in striving towards a noble life-goal. Evelyn is not addicted to exercise, even though she thought so, or may appear to be so based on the relatively high quantitative measures, as confirmed via the interview, which is a contradiction that supports Szabo et al.'s (2015) view that athletes interpret the symptoms of exercise addiction differently than recreational or leisure exercisers. The different interpretations gave rise to a false alarm in the literature suggesting that numerous athletes are prone to exercise addiction (McNamara & McCabe, 2012), often more prone than nonathletes (Blaydon & Lindner, 2002;Szabo et al., 2013a). Evelyn's proneness to exercise addiction, paired with no notable maladjustments in life, suggests that proneness (or risk determined with exercise addiction questionnaires) alone is not an index of dysfunction. Future studies should compare the differences in the levels of exercise addiction between non-competing recreational and competitive athletes, not simply on the bases of questionnaires, but by using follow-up interviews in the cases of established proneness or exercise addiction.

Untangling Passion From Addiction 310
While Evelyn experiences deprivation sensations when she must miss her training, her scores reflecting the severity of the symptoms, in terms of type and frequency, were lower, which supports earlier contentions that the presence of withdrawal symptoms, or deprivation sensation, does not pair up with exercise addiction, but their severity does (Szabo, 2010). Finally, in the period following her intense involvement in exercise, turning into sport, Evelyn had experienced positive changes in most life areas, which underpins the conclusion of the study that she has a passion for, but not addiction to exercise. These results suggest that actual cases of exercises addiction may be occur less frequently than expected based on the risk assessment (using a nomothetic/ questionnaire approach) in the literature.

Limitations
The study is not without limitation. The lack of generalizability is one obvious limitation. Lack of random selection (which is impossible in this area) and the participant's knowledge about the topic of the interview could have biased her responses. Like in most case studies, the author must rely on the inferred honesty of the participant. Further, the exercise per se and competition aspect of Evelyn's sport cannot be untangled, but so is that of competitive athletes studied in dozens of nomothetic investigations. Perhaps the explanation of the difference in the prevalence of exercise addiction, attributed to different interpretation of exercise addiction items by recreational and competing athletes  is an issue of an additional variable (i.e., competition) in the latter group. This feature should be systematically investigated in future works by a direct comparison of two matched groups, one recreational and one competitive. Still another limitation, is in comparing the eight life domains (Swarbrick, 2006) at present and in the past, since the latter relied on retrospective answers that could be subject to memory distortion. Perhaps only longitudinal studies could overcome this limitation.

Conclusions
The presented case study provides a real-life example of how self-perceived exercise addiction is only a mere reflection of both obsessive and harmonious passion in the maximal commitment to a sporting activity in a female body builder. The case study supports previous contentions that not the presence, but the strength of the deprivation sensations associated with exercise addiction may be instrumental in separating healthy-from unhealthy exercise pattern. The parallel between very high scores of obsessive passion and commitment in the examined person suggest that high internal pressure related to conformity in the training regimen may be part of the high commitment and that high obsessive passion can co-occur with high harmonious passion, the latter reflecting the joy and satisfaction derived from the results of training. The case study also revealed that the DSM-5 criteria for Non-Substance Related Disorders, when adopted for disordered exercise behaviour, may not apply, because of valid alternative interpretation of the nine criteria by the highly committed athlete; the lack of concordance of the DSM-5 outcome and the scores on the Exercise Addiction Inventory further justifies this point. The message from this case study is that future studies should look at passion and commitment too while examining the risk for exercise addiction, and more importantly that questionnaire-based risk scores may not reflect actual risk for dysfunction, thus their conceptual internal validity needs to be revisited.

Take Home Message
It is possible that nomothetic (quantitative) research, assessing the risk for exercise addiction, embeds a confounding overlap between passion, commitment, and exercise addiction, which yields false estimate of the Szabo 311 actual risk and prevalence of the dysfunction. Despite self-perceived exercise addiction, confirmed by various measures used in nomothetic research and DSM criteria for addiction, no signs of dysfunction and/or psychopathology could be detected in a female body builder, who is a competing athlete. The bulk of past research on exercise addictions should be re-evaluated with a view on the unlikely problematic behaviour mirrored by questionnaire scores.

Notes
i) External motivation would likely be a controlling factor and, therefore, it would increase scores on obsessive-, but not harmonious passion; future research should test this relationship outside the realms of exercise addiction.
