Personal and Social Responsibility Model: Differences According to Educational Stage in Motivation, Basic Psychological Needs, Satisfaction, and Responsibility

The purpose of this study was to apply the Personal and Social Responsibility Model (TPSR) and verify its effects on responsibility and motivation according to educational stage. For this, teachers from Physical Education and other subjects were trained and a pre-test and a post-test were carried out. The intervention was carried out over five months. The total sample comprised 408 students after the inclusion criteria were applied to the initial sample of 430, including being 192 students from 5th and 6th grade of Elementary (M 10.16; SD = 0.77) and 222 from Secondary (M = 12.86; SD = 0.70), with a confidence level of 95% and 5% error margin. The total number of students in the experimental group was 216, with 192 in the control group. The results reflected improvements in the experimental group in terms of experience motivation, identified regulation, amotivation, autonomy, competence, social responsibility, SDI, and BPNs (p < 0.05 and d Cohen > 0.2). The control group did not present differences in any variable. Considering the differences according to stage, the Elementary school group obtained values of p < 0.05 and d > 0.02 in experience motivation, amotivation, autonomy, competence, personal and social responsibility, SDI, and BPNs, which was not found in the Secondary school group. It is concluded that the TPSR may be applicable in both Elementary and Secondary schools to improve the motivation and responsibility of students, with the most favorable results for Elementary education students.


Introduction
The current educational system in Spain seeks to promote responsibility in the classroom, both in Elementary Education ("Develop individual and teamwork habits, effort and responsibility in the study" [1]) and Secondary Education ("Develop entrepreneurial spirit and self-confidence . . . to make decisions and assume responsibilities" [2]). This same can be seen reflected in the Organic Law 3/2020 of Education [3], which indicates the need to "integrate competences . . . reinforcing autonomy, reflection and responsibility" in its pedagogical principles.
Responsibility is a variable that has been widely studied for the promotion of healthy habits and behaviors in relation to the intention to be physically active or having fun [4], as well as for the improvement of psychological variables such as self-concept [5,6], school social climate [7][8][9], or resilience [10]. In the same way, the reduction of violence or disruptive behaviors has also been the object of study through the promotion of responsibility [7,11], studies of these variables being essential due to the increase in school violence [12,13].
In turn, responsibility has been widely studied as it relates to intrinsic motivation [7,8,[14][15][16][17] and with the basic psychological need for autonomy [18], as well application of the TPSR in the experimental group produced different results according to educational stage.
Based on the review carried out, it is hypothesized that: (1) The application of the TPSR in the general educational context and in PE will allow an improvement in internal motivational values, satisfaction of basic psychological needs, and the responsibility of the students; (2) Elementary school students will obtain higher values in the pre-test in the variables studied; (3) Elementary school students will have higher improvements than Secondary school students when applying the TPSR.

Design
This study is a quasi-experimental pre-post study [48] with a quantitative design [49]. In order to analyze the variables, a multiple-choice questionnaire were applied to the students before and after intervention. The study was conducted according to the guidelines of the Declaration of Helsinki [50] and approved by the Ethics Committee of the University of Murcia (1685/2017).

Participants
The sample consisted of 430 students from the fifth year of Elementary school to the fourth year of Secondary school from three public centers located in Murcia (Spain). After omitting the questionnaires that were not completed and implementing the statistical procedures to detect atypical cases (Mahalanobis's distance), the final sample was 408 students. There were 192 students from Elementary school (M = 10.16; SD = 0.77) and 222 from Secondary school (M = 12.86; SD = 0.70). The experimental group was made up of 216 students, and the control group 192 students.
All students completed an informed consent form that they passed on to their parents to participate in the study. Surveys indicated that these were completely anonymous in order to develop the methodology. In turn, they signed an agreement that the filming carried out could not be publicly displayed and would only be carried out for research purposes.

Measures
A closed question test with two parts was used in the present study: a first section with socio-demographic questions (gender and date of birth) and a second part with different aspects that were analyzed in this study. Motivation towards Education Scale: a continuous measure of motivation. The values ranged from a more intrinsic motivation to the most external causes, and finally amotivation. The Échelle de Motivation in Education was used [51] and validated by Nuñez et al. [52]. The questionnaire consisted of seven subscales: intrinsic motivation to know, to accomplish and to experience sensations (the most internal regulation); identified regulation (to obtain something external with which I identify); introjected regulation (e.g., "to prove myself that I am an intelligent person"); external regulation (e.g., "to get a more prestigious job"), and amotivation (a complete lack of motivation). The questionnaire was composed of 28 items preceded by the sentence "I go to school/high school because . . . ", with a seven-point Likert-type scale, from 1 (totally disagree) to 7 (totally agree), and was distributed into seven subscales, five of them containing four items and two of them containing three items. The internal consistency was α = 0.810; 0.752; 0.822 for intrinsic motivation to know, to experience, and to accomplish, respectively; identified regulation (α = 0.704); introjected regulation (α = 0.724); external regulation (α = 0.684); and amotivation (α = 0.777). The only variable that had less than 0.70 (0.684) was external regulation, an acceptable value according to Curran et al. [53]. Furthermore, the Self-determination index (SDI) was applied using the formula ((intrinsic motivation × 2 + identified regulation) − (introjected regulation + external regulation)/2 − (amotivation × 2).
Personal and social responsibility: The Spanish translation developed by Escartí et al. [16] of the personal and social responsibility questionnaire by Li et al. [54] was employed. The questionnaire is made up of two factors of seven items each: personal responsibility (e.g., "I want to improve"), and social responsibility (e.g., "Respect for others"). It was answered through a Likert-type scale with six response options, ranging from (1) totally agree to (6) totally disagree. The internal consistency coefficients for social responsibility were α = 0.801 for social responsibility and 0.782 in the case of personal responsibility.
Basic psychological needs. The purpose of this questionnaire was to measure the satisfaction of the three basic psychological needs.
The questionnaire by Moreno et al. [55,56] was used. It is composed of 18 items, six to assess each of the needs: competence (e.g., "I am confident to do the most challenging exercises"), autonomy (e.g., "I think I can make decisions in my workouts"), and relationship with others (e.g., "I feel close to my training partners because they accept me as I am"). The previous sentence is "In my trainings . . . " and the answers are collected on a Likert-type scale, whose score ranges from 1 (totally disagree) to 5 (totally agree). The alpha-cronbach's values were 0.717 (autonomy), 0.666 (competence), and 0.757 (relationship). We also used the Basic psychological needs index (BPNs) composed of the means of three variables (autonomy + competence + relationship)/3.

Procedure
The study began after making the appropriate contacts with those responsible for the different centers and accepting participation in the study. The interventions were carried out for a total of five months (second and third academic trimester), in which the participating teachers were previously trained in two 4 h sessions in the TPSR methodology. Questionnaires were completed before carrying out the intervention with the students in PE classes. Before beginning the research, the headmaster informed the parents of the study after holding an informational meeting with the volunteer teachers who participated in the study. The requirement was to spend 60% of the total class time applying the TPSR methodology, in which the PE teacher always participated, along with other school subjects. The questionnaires were completed in the classroom itself, in a quiet environment, taking a total of approximately 20 to 30 min to complete (depending on the age of the participants and their level of understanding).

Personal and Social Responsibility Model
The study consisted of the implementation of Hellison's [30] TPSR in the experimental group in an educational context. This model focuses on providing adolescents with experiences that allow the development of personal and social responsibility skills, progressively giving up responsibility, and has three basic pillars. The first is responsibility levels (Figure 1), which progressively increase to achieve educational values such as respect, effort, autonomy, and help to others. Second is the session structure. The five original parts of Hellison [57] were reduced to four, following other studies applied in this context [58]. The other parts of the session were (a) Relational time: The teacher interacted with their students to create an adequate climate and explain the purpose of the session and tried to put responsibility into practice, introducing the level to be worked at during the session; (b) Action responsibility: the responsibility level selected for the session was embedded in all the tasks; (c and d) Group meeting and co-evaluation: when a session ended, the students and teacher shared their perceptions about responsibility, and students evaluated their classmates', teacher's, and their own behavior (with the "thumbs up" strategy) [35]. Finally, the third pillar is the resolution of conflicts. During the classes, strategies were found to resolve conflicts of an individual type (e.g., strategy of five clean days) and group (e.g., the law of the grandmother) [59].

Implementation Fidelity
The need for a sustained implementation of the TPSR as well as the establishment of clear guidelines for its proper development make the concept of "continuous professional development" (CPD) [60] an essential aspect to guarantee success in teacher training and in obtaining results. Some of the most valuable tools for the CPD include systematic observation, and in the case of the TPSR, the so-called "Tool to Evaluate Education Based on Responsibility" (TARE) was used, which is very beneficial to adequately develop any investigation using the TPSR [61,62]. To ensure that the model was being properly applied, different sessions were filmed, each with different students. These were analyzed using the first TARE version (strategies used by teachers). At five-minute intervals, the observer noted the absence or presence of the categories into which the measures were divided (e.g., "Example of respect"). An observer was trained in the use of TARE and how to analyze the different sessions, providing feedback to the teachers with the positive aspects and how to improve for the next session. The teachers were invited to participate in different continuous monthly training sessions to clarify doubts and reach a consensus on aspects that may have raised doubts.

Statistical Analysis
For data analysis, the statistical program SPSS v.24.0 (Statistical Package for the Social Sciences, SPSS Inc., Chicago, IL, USA) was used, and a descriptive and inferential analysis of the results of the initial and final questionnaires of the participants was carried out to know the effect of the intervention on motivation, basic psychological needs and responsibility. Previously, the database was cleaned to detect atypical cases and two participants were eliminated due to having a p value < 0.01 in the Mahalanobis test. In addition, the values of skewness and kurtosis were analyzed, less than two in asymmetry and seven in kurtosis [53] being considered appropriate. Next, Cronbach's Alpha test was used to analyze reliability, obtaining a value of (>0.70) in the different variables.
We checked the results with parametric and non-parametric tests due to the lack of normality of the data, obtaining similar results. To the parametric test a repeated measures analysis including both groups and the variables at two time points was made. For the non-parametric tests, we divided the data into groups and used the U-Mann-Whitney Test (differences between groups) and Wilcoxon Test (differences in two time points) to compare the pre-test and post-test variables. All the statistics followed significance levels of p < 0.01 (**) or p < 0.05 (*). Additionally, the intervention effect size was estimated using Cohen's d [63]. The effect size was considered small when it was 0.2-0.49, medium when it was 0.50-0.8, and large when it was greater than 0.8, following Cohen. strategies were found to resolve conflicts of an individual type (e.g., strategy of five clean days) and group (e.g., the law of the grandmother) [59].

Implementation Fidelity
The need for a sustained implementation of the TPSR as well as the establishment of clear guidelines for its proper development make the concept of "continuous professional development" (CPD) [60] an essential aspect to guarantee success in teacher training and in obtaining results. Some of the most valuable tools for the CPD include systematic observation, and in the case of the TPSR, the so-called "Tool to Evaluate Education Based on  Table 1 shows the descriptive analyses of the different variables under study. The correlation between the variables was positive in all cases (p < 0.01), except for amotivation, which was negative. In turn, the asymmetry and kurtosis values were checked, showing adequate values in all cases, except for amotivation (2.408), with values of 2 being considered adequate according to Curran et al. [53].

Results of the Intervention
In order to know the effect of the TPSR model on the students (Table 2), the Wilcoxon non-parametric test was carried out for both the control group and experimental group. First, we checked the base point to both groups on pre-test. In this sense, it is noteworthy that the values were p < 0.05 for all variables using the Mann-Whitney U test in favor of the experimental group, except for amotivation, which was lower, and for introjected regulation, where there were no statistically significant differences. Similar results were obtained in the post-test, with the highest values in the experimental group.
We used the Wilcoxon test to see the difference between groups after the intervention (control group or experimental group). After that, the results were verified using parametric procedures (repeated measures tests and MANOVA), and the results were similar.
We considered how different variables changed between two measures (pre-test and pos-test). In this sense, the control group did not show statistically significant differences in any of the variables between the pre-test and the post-test; only personal responsibility was close to being significant (p = 0.063), and all values of the d-Cohen effect were <0.2. On the other hand, the experimental group showed statistically significant differences in knowledge motivation, experience motivation, identified regulation, introjected regulation, basic psychological needs for autonomy and competence, social responsibility, BPNs, and SDI, as well as in amotivation, which was significantly lower (p < 0.01), along with Accomplish motivation (p < 0.05). In this sense, the effect looks small in most variables, except for Knowledge and Accomplish motivation, and introjected and external regulation, where the value was <0.2. There were no differences in Personal responsibility, External regulation, or Relationship, but personal responsibility had a small effect size (>0.2). Finally, when comparing the effect size of intergroup differences, all variables increased their effect size from pre-test to pos-test in favor of the experimental group, with high effect sizes in knowledge, accomplish, and experience motivation, amotivation, competence, relationship, personal and social responsibility, SDI and BPNs (>0.80); in the pre-test these values either had a medium effect (0.5-0.8) or a small effect (0.2-0.49).

Differences in the Experimental Group According to the Educational Stage
Considering the experimental group and differentiating according to the educational stage (last two years of Elementary or Secondary school), we found the results that can be seen in Tables 3 and 4. In this sense, Table 4 highlights that, in the pre-test, the differences were found in experience motivation, identified regulation, introjected regulation, competence, social relationships, and social responsibility. All these variables were significant at p < 0.05 (except for experience motivation at p < 0.01), with a value close to significance in the SDI (p = 0.056), and with higher results in Elementary than Secondary school. According to the d-Cohen effect, only autonomy, amotivation and external regulation had no differences, and experience motivation was the only variable whose effect size was considered medium (0.5).      In the post-test, statistically significant differences were observed for experience motivation, external regulation, amotivation, personal responsibility, and SDI. In this case, the external regulation and amotivation variables were higher in Secondary school. The values of d-Cohen effect were near to medium effect in experience_motivation, external regulation, personal responsibility, and SDI (0.4-0.5), similar to the p-value results, excluding amotivation.
Finally, Table 5 compares the experimental group with the results of the intervention. Regarding the Elementary school group, statistically significant differences were obtained that were not found in the Secondary school group in knowledge motivation, experience motivation, accomplish motivation, amotivation, social responsibility, and BPNs. In contrast, the Secondary school group only obtained p values < 0.01 for external regulation, which was not found in the elementary School group. According to d-Cohen test, the values for Secondary students were very small for all variables, but for Elementary students, a small effect was found in amotivation, autonomy, competence, personal and social responsibility, SDI, and BPNs. Legend: M = mean; SD = Standard deviation; SDI = Self-determination index; BPNs = Basic Psychological Needs Index; ** = p < 0.01; * = p < 0.05.

Discussion
The main objective of this study was to verify the effects of the TPSR on different variables following the SDT, specifically, the levels of motivation, basic psychological needs, and responsibility of the students. It was intended to analyze the differences in the application of the model, taking into account whether the students were from Elementary school or Secondary school.
Considering the first proposed hypothesis, it is noteworthy that the experimental group, despite having obtained significantly higher values in almost all the variables in the pre-test, was the one that managed to improve these values at the end of the intervention. In contrast, the control group did not significantly modify any of the variables studied. In this sense, it is noteworthy that positive results were found in the motivation variable, obtaining higher values in the most self-determined regulation and a reduction in amotivation. This is in line with other authors who have applied this methodology and found improvements in intrinsic motivation [36,54], which also can be extended to the participating teachers, having greater satisfaction with their own teaching, and allowing them a greater transfer of autonomy to the students [7].
In turn, the BPNs improved, especially those of autonomy and competence perception, but this was not the case in the need for social relationships, which did not change. These results are consistent with different studies, such as those by Manzano-Sánchez et al. [18], where autonomy was the psychological need that benefited the most from the application of the TPSR, probably due to the fact that level 3 of the model is called "Autonomy" and TPSR strategies include the progressive surrender of autonomy as a basic pillar of the model. The perception of competence also improved, as in the study by Menéndez-Santurio et al. [41], where applying the TPSR in 143 Secondary school students obtained improvements in this need and also, unlike in our study, in those of relationship. This may be because, in the indicated works, the TPSR was applied only to PE, a subject where social relationships are practically necessary and where this methodology can help to promote said relationships due to the characteristics of the subject [64].
On the other hand, responsibility levels increased after the application of the model. The differences were only statistically significant in social responsibility, as in the study by Pérez-Ordás et al. [43], and contrary to Manzano-Sánchez et al. [18], where improvements were seen in personal responsibility. Other studies that have applied the TPSR have found improvements in both levels of responsibility [33,41], so it is interesting to indicate that there is still work to be done to reach conclusions on this variable. It is noteworthy that this methodology has not only shown very favorable results in psychomotor [46] and psychological aspects such as motivation and self-efficacy in exercise [47], but researchers such as Melero-Cañas et al. [65] analyzed the application of the TPSR in relation to the physical condition of Secondary school students and also improvements with a healthy lifestyle. The intervention implemented by Martins et al. [66] demonstrated that sport represents a unique opportunity within the educational process to establish values, beliefs, attitudes, and practical habits of relationships and cooperation that generate social responsibility in youngsters. Furthermore, Carreres-Ponsoda et al. [67] conclude that the TPSR model has the potential to be adapted and implemented also with flexibility in youth sport competition contexts in order to improve personal and social responsibility, prosocial behavior and self-efficacy. Finally, the study by García-Castejón et al. [4] is very interesting given that they found improvements both in the most self-determined motivation, as well as in the satisfaction of BPNs and in responsibility in a Secondary school by combining the TPSR with Teaching Games for Understanding in PE. This study should be indicated in context with other hybridizations performed with the TPSR, such as the use of the Sport Education Model, the most widespread model and one in which very positive results have been seen [41,68].
Based on the second of the hypotheses, the results obtained indicate higher values in the variables of motivation, satisfaction of BPNs, and responsibility for Elementary school students. Other authors have obtained similar results [33,69], where the Elementary education stage is shown to be the ideal one at which to work on motivational aspects.
Finally, this is the second study where the differences have been seen when applying the TPSR between two educational stages as a third hypothesis. In this sense, the research by Sánchez-Alcaraz [33] corroborated our results by applying the TPSR in PE, where the results of the intervention were better for Elementary school students. Although, unlike his study, in the present investigation the model was applied in PE and in other school subjects, and not only in PE. Other studies have verified the results in the sample taking into account students from both stages, but without differentiating between Elementary and Secondary school [7,36]. Therefore, there is still much to be investigated in this field of TPSR within the general educational context.
As the main limitations of this research, it should be noted that although both groups were quite similar in sample size, an attempt could have been made to obtain a larger sample and differentiate between the students who applied the model only in PE and in other subjects. In turn, it could have been considered to include the point of view of families or teachers when collecting the data to compare the results. On the other hand, the application of the TPSR was always of a teaching percentage greater than 60% of the total, but it would have been interesting to be able to apply it with all the participating teachers as a center project. It is also noteworthy that the pre-test values were higher in the experimental group and it could influence the results. Finally, the intervention was carried out for five months, and it would have been interesting to be able to carry it out during a total academic year.
Future studies could corroborate the results of the present study by applying the TPSR and even experimenting on the hybridization of methodologies within the general educational context. Considering different socio-educational levels can also be interesting in order to assess the variables under study. Additionally, it would be useful to understand the influence of the TPSR on variables such as emotional intelligence [70] or resilience as psychological variables, in addition to being able to extend the studies longitudinally, monitoring them over time.

Conclusions
The application of the TPSR in the educational context may be suitable both for teaching in Elementary school and in Secondary school students. The results obtained indicate that Elementary school students may have better results for self-determined motivation and responsibility after the intervention of TPSR compared with Secondary students. In turn, they are the ones who obtain the greatest benefits in the application of the TPSR, since the results of the intervention indicated improvements in both experimental groups, although these results were higher for the youngest students.
