Data concerning the psychometric properties of the “Profile of Emotional Competence” questionnaire administered to a sample of athletes and non-athletes

Emotional Intelligence (EI) can be defined as an “ability to monitor one's own and others' feelings and emotions, to discriminate among them and to use this information to guide one's thinking and actions” (Salovey and Mayer, 1990) [1]. As such EI plays a major role in sport sciences. Studies conducted so far have shown contrasting findings. The paper contains data concerning the psychometric properties of the “Profile of Emotional Competence” questionnaire administered to a sample of 479 subjects (239 athletes, 240 non-athletes, age ranging from 12 to 18 years old, 239 men, and 240 women) in order: i) to explore EI between athletes and non-athletes students and ii) to examine differences in EI of young participants in terms of gender and age.

Value of the data
These data could be further statistically replicated, and eventually pooled together with other similar data, in order to explore the role of emotional intelligence among athletes, a topic often overlooked in the extant scholarly literature.
These data could be useful for sports managers, coaches, and athletes, as well as for sports scientists and researchers, for designing and implementing ad hoc training programs and interventions, taking into proper account emotional aspects.

Data
Emotional Intelligence (EI) can be defined as an "ability to monitor one's own and others' feelings and emotions, to discriminate among them and to use this information to guide one's thinking and actions" [1]. As such EI plays a major role in sport sciences. Studies conducted so far have shown contrasting findings. This paper contains data concerning the psychometric properties of the "Profile of Emotional Competence" (PEC) questionnaire, developed by Brasseur et al. in 2013 [2], here administered to a sample of 239 Tunisian athletes versus 240 non-athletes, in order to: i) explore EI between athletes and non-athletes students and ii) to examine differences in EI of young participants in terms of gender and age.
General descriptive characteristics of each item and of each sub-scale of the PEC questionnaire are reported in Tables 1 and 2, respectively. Reliability statistics (item-total correlation and Cronbach's alpha coefficient in case of item exclusion) are shown in Table 3. Regression analyses for the subscales of the interpersonal and intrapersonal domains are shown in Tables 4 and 5, respectively, whereas regression findings for summary scores (global, interpersonal and intrapersonal domains) are reported in Table 6.

Experimental design, materials and methods
The protocol of the current study received ethical clearance by the Ethical Committee of the National Centre of Medicine and Science in Sports (CNMSS) of Tunisia before questionnaire administration and data collection. Each participant volunteered to take part into this study, after signing an informed consent. Means, standard deviations, kurtosis and skewness were computed for each item and sub-scale of the PEC questionnaire. Regression analyses were performed to shed light on the predictors of each sub-scale/domain of the PEC questionnaire.
All statistical analyses were performed using the commercial software Statistical Package for Social Science (SPSS, version 24.0, IBM, Chicago, IL, USA). Figures with a p-value o 0.05 were considered statistically significant.
These data could be useful for sports managers, coaches, and athletes, in that they could enhance coaching practices and lead to better performances and results. Psychologists can also use the PEC inventory to distinguish between participants' gender and age and athletes and non-athletes.
