The present research aims to analyse the psychometric properties of the AF5 questionnaire for its adaptation for use with young people during a lockdown period. Research was conducted with a sample of 534 students aged between 13 and 17 years (M = 14.49; SD = 1.805). Exploratory factor analysis was conducted using the FACTOR program and confirmatory factor analysis was conducted using the M-PLUS 7 program. Results indicate that a four-dimensional model is most appropriate for bringing together the emotional and physical dimensions. Further, 11 items were removed due to poor factor loadings. The majority of factors were directly and positively correlated (99%; p < .01). The data obtained supports conclusions that the AF-5 meets validity and reliability requirements for it to be considered a useful instrument for use with young people during the COVID-19 lockdown period.

An appeal has been issued to the scientific community to investigate physical, mental and emotional states, and pro-social behaviours during the COVID-19 pandemic. Hence, this study aims to investigate adolescents’ self-concept before and during a lockdown period in relation to gender and type/amount of physical activity or sports. The pre-lockdown sample of 366 adolescents were aged 13–17 years (M = 15.51 ± 0.65), of whom 192 (52.5%) were females and 174 (47.5%) were males. During the lockdown, the age range of the sample was 13–17 years (M = 14.57 ± 1.47), of whom 82 (60.3%) were females, and 54 (39.7%) were males. The Form-5 Self-concept Questionnaire (AF-5) was used to measure adolescents’ self-concept. There was a reduction in adolescents’ overall self-concept during the COVID-19 pandemic, which was positively associated with emotional well-being, with family and peers being essential factors in the development of an appropriate self-concept. Furthermore, girls’ self-concept, especially academic self-concept, was higher than that of boys during the lockdown. However, both physical and emotional self-concept were higher for boys than girls before the COVID-19 lockdown, although no differences were found during the lockdown. The findings reveal that physical activity was positively correlated to self-concept before and during the COVID-19 lockdown.

The COVID-19 lockdown has negatively affected individuals’ welfare. However, there has been no research published heretofore about the levels of self-concept (SC) in adolescents, nor how having practised martial arts (MA) or any physical activity (PA) before the lockdown may have influenced the SC in that time. Hence, this study aimed to analyze some demographic, physical, and psychosocial parameters in Spanish adolescents throughout the COVID-19 quarantine through a cross-sectional investigation, establishing correlations among these factors. Methods: The present study had a descriptive, comparative, and cross-sectional design. The sample comprised of 54 (39.7%) male and 82 (60.3%) female Spanish adolescents aged 12–18 (M = 14.49; SD = 1.80). An ad-hoc questionnaire collected sociodemographic data; the self-concept Form 5 (AF5) questionnaire obtained data on SC dimensions. Results: There were some differences among the SC dimensions, with family and academic dimensions having higher values than the physical and emotional ones. Females’ academic SC was higher than that of males (p = 0.019). The practice of PA before the lockdown was positively associated with physical (p < 0.001) and social (p = 0.012) SC, yet there was no significant association between the previous practice of MA and SC (p > 0.050). Conclusions: the findings suggest that the COVID-19 lockdown negatively affected Spanish adolescents by decreasing their total SC and some dimensions of it, although PA may buffer psychological harmfulness in adolescents.
