Mental health in children and adolescents has become an increasingly important topic in recent years. It is against this backdrop that physical education and school sports play an important role in promoting psychological wellbeing. The aim of this review was to analyse interventions for improving psychological wellbeing in this area. To this end, a literature review was conducted using four databases (WOS, SPORTDiscus, SCOPUS and ERIC) and the following keywords: psychological wellbeing, physical education, and school sports. Twenty-one articles met the inclusion criteria. The results showed that interventions varied greatly in terms of duration and used a wide range of strategies (conventional and non-conventional sports, physical activity, games, etc.) for promoting psychological wellbeing, primarily among secondary school students. There was a lack of consensus as to the conceptualisation of the construct of psychological wellbeing, resulting in a variety of tools and methods for assessing it. Some studies also suggested a link between psychological wellbeing and other variables, such as basic psychological needs and self-determination. Finally, this study provides a definition of psychological wellbeing through physical activity based on our findings.

This study is based on the need to explore the different strategies and interventions that seek to develop psychological well-being (PW) in scholars (children and adolescents aged 9–19 years) through physical education and school sports by bearing in mind other variables that can extensively facilitate PW in these students. This study analyzed 504 research works published between 2010 and 2020, and 23 were selected for this review because they met the inclusion criteria. The results showed that the most studied variables were: motivation, academic performance, teaching climate in physical education (PE) teaching styles, parents’ relationships and school environment. The literature review carried out in this study reveals the need to consider PW with other relevant variables, and the importance of doing so from a community approach, in which all systems (parents, school and government) are active participants, and contribute to generate a positive environment for all. Finally, school professionals should be aware of the need to stimulate their students’ PW because government organizations should be interested in promoting such a policy in this population.

The aim of this study was to develop and validate a scale to assess psychological well-being in physical activity and sport context, based on Ryff's theory (2014) and the definition of psychological well-being proposed Piñeiro et.al (2021). For that purpose, a Likert type instrument with 51 items was designed. The scale was applied to 584 participants (63% women) with aged between 15 and 29 years (M=19.05;SD 2.97)), from secondary schools and universities from different autonomous communities of Spain. After the statistical analysis, eliminating the items with low values, the final instrument was composed with 40 items (6 dimensions). The results showed that the scale manifests high reliability (α= .965), as well as high levels of explained variance. In conclusion, the research provides a valuable instrument, supported by a scientific theoretical basis, for the evaluation of psychological well-being through physical activity and sports practice in Spanish youth. Keywords. Mental Health; Physical Activity; Eudaimonia; Assessment; Youth.

The aim of this study was to translate and validate into Spanish the Life Skills Scale for Sport (LSSS) designed and validated by Cronin and Allen. The scale is divided into eight sub-dimensions: goal-seeking, teamwork, time management, emotional skills, interpersonal communication, social skills, leadership, and problem solving. Method: For the translation process, a validation between languages was performed. A double procedure was carried out with bilingual researchers related to the subject, translating from English to Spanish and, conversely. Subsequently for validation, 1251 students (59.8% women) between 15 and 29 years old from Spain and Chile answered the questionnaire. Results: Comparing initial results, the translated terms matched, and no relevant mismatch was found. The confirmatory factor analysis supported the factorial structure proposed by the original authors, showing acceptable fit indicators (RMSEA: 0.048; CFI: 0.93; TLI: 0.92), satisfactory internal consistency coefficient (0.980) and adequate item-total correlation (0.630). Conclusion: The instrument proves to be consistent in the evaluation of life skills in the Spanish-speaking population, presents adequate psychometric properties and is a reliable and valid instrument for the evaluation of life skills in contexts of physical activity and sport with a young population aged 15 to 29 years.
