The cost of the perfect body: influence mechanism of internalization of media appearance ideals on eating disorder tendencies in adolescents

BackgroundSome studies have examined the relationship between internalization of media appearance ideals and eating disorders. However, few have discussed the relationship between eating disorder tendencies. To fill this research gap, this study was to explore the influencing mechanisms of internalization of media appearance ideals on adolescents’ eating disorder tendencies in Chinese cultural context.MethodThe Sociocultural Attitudes Towards Appearance Questionnaire, Eating Attitude Test-26, Physical Self-Description Questionnaire, Body Image Depression Questionnaire and Multidimensional Scale of Perceived Social Support were employed in this study to investigate 1523 adolescents. The collected data were analyzed using SPSS 26.0 and AMOS 24.0.ResultThe results showed that: (1) internalization of media appearance ideals had a significant positive predictive effect on adolescents’ eating disorder tendencies; (2) internalization of media appearance ideals significantly influenced adolescents’ eating disorder tendencies through the mediating role of body esteem and body image disturbance respectively, and also influenced eating disorder tendencies through the chain mediating of both; and (3) social support played a moderating role between body image disturbance and eating disorder tendency.ConclusionOur findings suggest distinct pathways through which internalization of media appearance ideals may influence adolescents’ eating disorder tendencies. It is suggested that reducing body image disturbance and enhancing social support can help reducing eating disorder tendency.

A115: Revision of the Chinese Version of Physical Self-Description Questionnaire-Short for Middle School Students

Purpose: The Physical Self-Description Questionnaire -Short (PSDQ-S) is one of the world's recognized effective tools for measuring Physical Self-Concept (PSC). However, Latent profile analysis of the physical self-description among Chinese adolescents only supported the 3-dimensional model of PSDQ-S, that is, it could only distinguish the Physical Activity (PA), Appearance, and Body Fat of Chinese children and adolescents, but could not effectively distinguish the 8 dimensions of Coordination, Flexibility, Strength, Endurance, Sport, Global Physical, Health, and Global Esteem. It cannot meet the needs of PSC measurement in the field of sports psychology in China. The purpose of this study was to revise the PSDQ-S for Chinese middle school students, and to test its reliability, validity, and gender measurement equivalence in Chinese middle school students. Methods: A stratified random cluster sampling method was used to conduct a questionnaire survey on the Chinese version of PSDQ-S. 2505 middle school students in grades 7-12 (12-18 years old) were selected from seven administrative geographic regions of North China, Northeast China, East China, Central China, South China, Southwest and Northwest China, among which 1239 were male subjects, with an average age of (15.07±1.93) years, Female subjects were 1266, with an average age of (15.02±2.04) years. SPSS 24.0 and Mplus 8.3 were used for data analysis. Results: Eight common factors were extracted by exploratory factor analysis, and the cumulative variance interpretation rate was 79.45%. Confirmatory factor analysis support 8 factor model hypothesis (χ2 / df = 1.846, CFI = 0.939, TLI = 0.929, SRMR = 0.050, RMSEA = 0.061). The 8 dimensions were Physical Activity, Appearance, Body Fat, Flexibility & Coordination, Endurance, Sport, Global Physical and Health. The average variance extraction of each factor of the Chinese version PSDQ-S convergence validity index was greater than 0.50, and the combination reliability was greater than 0.60. The gender equivalence hypothesis was established. Conclusions: The revised Chinese version of PSDQ-S has good reliability, validity, and gender equivalence. It can be used as a measurement tool of PSC of Chinese middle school students.

A Meta-Analysis of the Effects of Taekwondo on Physical Self-Concept.

In this meta-analysis we explored whether Taekwondo practice has improved its participants' physical self-concepts. We also tested the mediating influence of factors in past research such as country, participant age, and measurement properties in their associations with these taekwondo effects. We reviewed extensive data collected from Chinese, English and Korean participants in articles listed in Cnki, Wanfang, PubMed, Web of Science, KISS, RISS, and DBPIA databases. First, we evaluated the methodological quality of these published articles with Review Manager 5.4 software according to the Cochrane System Evaluation Manual. Then, we used Comprehensive Meta-Analysis 3.7 software for statistical analysis. We based these analyses on nine research studies containing a total of 1154 participants. We found a significant association between taekwondo activity and an improved body self-concept (ES = .688, p < .001). Subgroup analyses showed a stronger association between these variables in Korea (ES = .90, p < .001) than in China (ES = .34, p < .001), a stronger association for children (ES = 1.04, p < .001) compared to adults (ES = .46, p < .001), and a stronger association with the modified version of the Physical Self-Description Questionnaire (PSDQ) (ES = .99, p < .001) than with the original PSDQ (ES = .57, p < .001). We concluded that practicing Taekwondo led to improved physical self-concept, especially in a younger population. In addition, the experimental design and measurement methods may influence the apparent link between these variables.

Promoting mental health in children and adolescents with disabilities through school-based physical activity intervention during the COVID-19 pandemic

BackgroundChildren and adolescents with disabilities had lower levels of physical activity (PA) and mental health than their typically developing peers during the COVID-19 pandemic. ObjectivesThis study aimed to examine the effects of school-based PA intervention on quality of life (QoL) and self-concept (SC) in children and adolescents with intellectual disabilities (IDs), physical disabilities (PDs), and hearing impairments (HIs). MethodsFifty-eight participants with disabilities (Mage = 15.0 ± 2.2 years) were recruited from five Hong Kong special schools during the COVID-19 pandemic. School-based PA intervention included (un)structured PA, teacher training, and parental involvement. PA levels, QoL, and SC were measured by the Physical Activity Questionnaire for Older Children, Pediatric Quality of Life Inventory, and Physical Self-Description Questionnaire Short Form, respectively. PROCESS macro, linear mixed model, two-way ANOVAs, and linear regression were used in the data analyses. ResultsThere were positive intervention effects on PA levels (Mean Difference [MD] = 0.33, 95% CI [0.06, 0.60]) and SC (MD = 0.38, 95% CI [0.03, 0.73]) in participants with disabilities; and social QoL (MD = 14.10, 95% CI [0.43, 27.78]) only in participants with IDs. SC improvement significantly mediated the relationship between PA and QoL improvements in participants with disabilities (β = 0.304, R2 = 26%) and males (β = 0.463, R2 = 10%). Contextual factors significantly moderated PA levels and mental health. ConclusionSchool-based PA intervention improved QoL through positive changes in SC in children and adolescents with disabilities during the COVID-19 pandemic. Future studies should consider stress, anxiety, and depression to explore the effectiveness of school-based PA intervention in children and adolescents with disabilities.

Physical Self-Concept and Physical Activity in Children with Congenital Heart Defects-Can We Point Out Differences to Healthy Children to Promote Physical Activity?

Children with congenital heart defects (CHD) are at high risk for cardiovascular disease in addition to their congenital disease, so it is important to motivate this group of patients to live a physically active lifestyle. A potential influencing determinant of younger children's physical performance is the physical self-concept. The objective of the present study was first to evaluate the correlation between the physical self-concept (PSC) and the participation in physical activities (PA) of a representative group of children with congenital heart disease (CHD), and second to point out differences in comparison to their healthy peer group. Using the database of PA of the S-BAHn-Study we focused on physical self-concept assessed by the German version of the Physical Self-Description Questionnaire. We compare the obtained data of children with CHD to a representative age-matched sample of 3.385 participants of the Motorik Modul Study. N = 1.198 complete datasets could be included in the analyses. The mean age of patients was 11.6 ± 3.1 years. For the total cohort of patients with CHD and the reference group, PA correlated significantly with a positive PSC (p < 0.001). PA was significantly reduced in all groups of patients despite the severity of their heart defect (p < 0.001). Remarkably, PSC did not differ statistically significantly in patients with simple CHD from the reference collective (p > 0.24). According to this representative survey, there is a clear relation between PA and PSC in the cohort of healthy children and the group of children with CHD throughout the severity of their heart defects. Although PSC did not differ in patients with simple CHD and their healthy peer group, PA was significantly reduced. This gap invites us to reflect on how we could break new ground to promote a physically active lifestyle in children with CHD regardless of the severity of their cardiac defects.

Physical Self-concept in Mexican Adolescent men and women

The purpose of the present study was to compare the profiles of physical self-concept between men and women primary and secondary Mexican school students. A total sample of 1146 participants, 550 women and 596 men, aged 11-16 years participated in this study. A quantitative approach with a descriptive and transversal survey design was used. All the participants completed the Physical Self-Description Questionnaire. The results of the one-way multivariate analysis of variance, followed by the one-way univariate analyses of variance, showed that compared with the women, the men obtained higher scores on the subscales health, coordination, activity, sports competence, strength, flexibility, endurance and global physical self-concept. However, in the body fat, appearance and global self-esteem subscales statistically significant differences were not found. Because of the differences between men and women in their perception of physical self-concept found, these findings suggest that in order to design any intervention for improving the perceived physical self-concept of the students, the variable sex should be taken into account. Keywords: physical self-concept, student´s beliefs; sex differences; self-perception, adolescents.

The Role of Perceived Sports Competence and Sport Anxiety in Determining Self-Talk in Elite Athletes

The purpose of our research was to investigate the role of sport anxiety and perceived sports competence in determining the utilization of self-talk in elite athletes. Fifty six female (X̅age=24.62±3.40) and 65 male (X̅age=24.50±6.50); a total of 121 (X̅age=24.56±5.28) athletes who have at least three years of competitive experience and have previously represented Turkey with the national athlete title at international sports competitions were voluntarily participated in the study. Participants were given a personal information form along with the sports competence subscale of the physical self-description questionnaire which was developed by Marsh Richards, Johnson, Roche and Tremayne (1994) and adapted into Turkish by Marsh, Asci and Marco in 2002; the sport anxiety scale which was developed by Smith, Smoll, Cumming and Grossbard (2006) and adapted into Turkish by Akyol, Altintas, Sezer and Asci in 2016; the self-talk questionnaire which was developed by Zervas, Stavrou and Psychountaki (2007) for the purpose of determining athletes’ self-talk forms and was adapted into Turkish by Engur in 2011. After exploring a normally distributed data, the hierarchical regression analysis was used to determine the role of sports competence and sports anxiety in predicting the athletes' self-talk types. As a result of the research, statistically significant differences in both sports competence and self-talk usage levels were found between groups according to sport type and a statistically significant relationship was found in predicting motivational self-talk for both competition experience and sport type.

Physical Activity as a Means to Improve Subjective Vitality of University Students

ABSTRACTPurpose: This study compared physical self-concept and subjective vitality of police, physical education, and psychology students. Moreover, the study investigated whether students who reported a higher level of physical activity differently rated physical self-concept and subjective vitality and whether physical activity was associated with subjective vitality. Methods: The study sample included 422 university students (249 females) from three state academic institutions: University of Criminal Investigation and Police Studies (n = 165), Faculty of Sport and Physical Education (n = 156) and Faculty of Psychology (n = 101). The mean age was 20.85 ± 3.59 years. They completed a physical self-description questionnaire, the subjective vitality scale, and a physical activity questionnaire using the Survey Monkey platform. Multivariate analysis of variance investigated the differences in physical activity, physical self and vitality, while regression analysis investigated the association of physical self and physical activity with subjective vitality. Results: Police students and physical education students reported higher levels of physical activity and perceived higher their own physical self and subjective vitality than psychology students. From the whole sample, students who were sufficiently physically active also scored higher on physical self-concept and subjective vitality. There was a significant association of physical activity level with subjective vitality. Conclusion: Physical activity was directly associated with students’ subjective evaluation of their own health. It can be concluded that students should aim to attain a minimum of 150 min per week of physical activity. Students and faculties should be involved in the attainment of minimal levels of physical activity. This could improve students’ subjective perception of self, along with objective measures of health and wellbeing.

The Associations Among Physical Activity, Quality of Life, and Self-Concept in Children and Adolescents With Disabilities: A Moderated Mediation Model.

ObjectivesThis study aimed to examine a moderated mediation model of the associations among physical activity (PA), quality of life (QoL), and self-concept (SC) in children and adolescents with physical disabilities (PDs) and intellectual disabilities (IDs).Materials and MethodsA total of 288 children and adolescents with PDs and IDs, aged between 6 and 17 years, were recruited from 16 special schools in Hong Kong. PA, QoL, and SC were measured using the Physical Activity Questionnaire for Older Children (PAQ-C), Paediatric Quality of Life Inventory (PedsQL), and Physical Self-Description Questionnaire Short Form, respectively. Mediation (i.e., PA, QoL, and SC) and moderation analyses (i.e., age, sex, and parental education level) were conducted by structural equation modelling (SEM) using the M plus and PROCESS macro for SPSS.ResultsPhysical activity (PA) was positively associated with SC (PDs: β = 0.373; IDs: β = 0.343), and SC significantly mediated the associations between PA and QoL in children and adolescents with PDs (parent proxy-report QoL: β = 0.114; self-report QoL: β = 0.141) and IDs (self-report QoL: β = 0.204). The mediating effects of SC accounted for 16 and 15% of the total effects of PA on QoL (parent proxy-report and self-report) respectively, in participants with PDs, and 8 and 4%, respectively, in those with IDs. Males and participants with higher parental education levels reported stronger associations among PA, QoL, and SC than their counterparts.ConclusionThis study supports mediating and moderating effects on the associations among PA, QoL, and SC in children and adolescents with PDs and IDs. Future researchers should consider PA intervention in mental health services and provide tailor-made PA programmes based on personal and environmental factors for children and adolescents with disabilities.

Physical Self-Concept and Physical Activity Levels between Physical Education Major and Non-Physical Education Major College Students

The study was designed to examine differences in physical self-concept and physical activity between physical education major and non-physical education major college students. Physical self-description and physical activity questionnaires were administered to 161 students. The Physical Self-Description Questionnaire (PSDQ) has 11 factors namely, action, appearance, body fat, coordination, endurance, flexibility, health, sport, strength, global physical, and global esteem. In the main effect, it was found that physical education major and non-physical education major students vary in the levels of their physical self-concept. Physical education majors were found to have higher physical self-concept in terms of action, coordination, endurance, sport, strength, and global esteem. Similarly, the physical education major and non-physical education major students differ in the levels of their physical activity. Among the 11 factors of physical self-concept, sport best predicts the level of physical activity of the students.

The relations between body mass index, motor skills, and physical self-concept in determining physical activities of junior karatekas

The aim of this research was to examine the contribution of body mass index (BMI), motor skills and physical self-concept in explaining the physical activity (PA) of adolescent karatekas (N=148). The average age of participants was 16,56 years (± 1,14). The following measuring instruments were used: Body Mass Index (BMI), Eurofit Physical Fitness Test Battery, Physical Self-Description Questionnaire (PSDQ), and Physical Activity Questionnaire for Adolescents (PAQ-A). The Cronbach's alpha coefficient was used to determine the internal consistency of the questionnaires. The results of the hierarchical analysis showed that the predictor variables explained 18,5% of the total variance of the criterion PA of junior karatekas. With their positive direction, the independent variables of the physical self-concept strength (β = 0.049; p &lt; 0.01), flexibility (β = 0.037; p &lt; 0.01) and self-respect (β = 0.019; p&lt; 0.05) showed the maximum statistically significant contribution to predicting the variability of the participants' PA, which means that junior karatekas who manifest the higher level of perception on those variables exhibit the higher level of PA. This study confirmed that the applied instruments are valid and suitable to predict PA among adolescent athletes in Serbia.

Impact of Activity Tracker Usage in Combination with a Physical Activity Intervention on Physical and Cognitive Parameters in Healthy Adults Aged 60+: A Randomized Controlled Trial.

Regular physical activity (PA) is of central importance for healthy aging and has a well-known impact on helping older adults maintain their cognitive and physical health. Thus, we aimed to compare the effectiveness of two physical activity interventions primarily conducted at home (print-based or web-based vs. web-based plus the use of an activity tracker) on cognitive and physical health parameters in older adults. Data of participants (n = 551, 60–80 years) were analyzed after being randomly allocated to a waitlist control group (CG), a web-based or print-based intervention group (IG) or a web-based intervention group that also included the use of an activity tracker (AG). Measured parameters were grip strength, endurance (two-minute step test), gait speed (four-meter walk test), cognition (Simon task; balanced integration score (BIS), reaction time and accuracy) and physical self-concept (Physical Self-Description Questionnaire (PSDQ)). We found the highest effect sizes in all measured dimensions for AG (grip strength, endurance, gait speed, reaction time, physical self-concept), followed by IG (endurance, gait speed, reaction time, physical self-concept) and CG (endurance, gait speed, BIS). Findings suggest that a combined web-based and activity tracker intervention may improve physical functions, physical self-concept, and cognition in community-dwelling older adults.

Motor Competence–Related Age and Living Environment in Girls: A Cross-Sectional Study

This study aims to investigate the effect of age and urban and rural living environments on children’s actual and perceived motor competence. To that end, 320 female students aged 8–12 years were selected through random cluster sampling. The perceived motor competence of the participants was assessed using Marsh’s Physical Self-Description Questionnaire, and their actual motor competence was measured by the Test of Gross Motor Development-3. The results showed significant differences between urban and rural girls in perceived and actual motor competence (p &lt; .05). However, age did not make any significant difference in motor competence (p &gt; .05). The most significant differences in actual and perceived motor competence between urban and rural girls were observed in girls aged 8 and 10 (p &lt; .05). The findings also indicated that rural children performed better in actual motor skills, especially ball skills. Therefore, based on the findings, it was concluded that the rural environment could have a greater impact on actual motor competence.

EXPLORING PSYCHOLOGICAL WELL-BEING AND BODILY IDENTITIES FORMATION OF YOUTH SPORTS ADAPTED PRACTITIONERS. COMPARISON OF PEOPLE WITH CONGENITAL AND ACQUIRED DISABILITIES.

This cross-sectional and randomized block design (RBD) study, after describing the physical self concept in people with motor disabilities who play sports, examined the differences among athletes with congenital and acquired disabilities and assessed the influence of age of disability onset of disability on physical self-concept perceptions. Participants were 201 athletes with acquired motor disabilities and 185 athletes with congenital motor disabilities. Ages ranged from 12-28 years, and athletes were both male and female. For RDB, we used a specific function of SPSS 29.0 to create and compare two random samples of 100 participants with congenital disabilities and 100 participants with acquired disabilities. All participants completed an adapted version of the Physical Self-Description Questionnaire (PSDQ-S; Scarpa et al. 2010), on which we tested group differences with ANOVA. We also used Pearson correlation analysis to examine the relationship between both ‘years without disability’ and dimensions of physical self-concept. All participants achieved positive average scores. Participants with acquired disabilities had higher average physical self-concept scores, relative to those with congenital disabilities. Early onset of physical disability negatively affected self-esteem, and most dimensions of physical self-concept.

Flourishing in Young Adults: The Role of Achievement Goals, Participation Motivation, and Self-Perception Levels in Physical Activity Contexts

This study aims to determine how achievement goals, participation motivation and self-perception levels in physical activity environments relate to the flourishing of young adults. The general purpose of the study was also to examine differences in selected variables of young adults flourishing in physical activity environments. To achieve our aims, the recruited sample consisted of 580 young adult exercisers ranging in age from 18 to 40 years from fitness centers in Izmir, Turkey. Participants completed a personal information form, the Flourishing Scale, the 2 × 2 Achievement Goals Questionnaire for Sport (2 × 2 AGQ-S), the Situational Motivation Scale (SIMS), and the Physical Self-Description Questionnaire (PSDQ). We examined correlations, regressions, and path models with our measured variables. Flourishing relates significantly (p &lt; 0.001) and positively with global self-esteem, the mastery-approach goal, intrinsic motivation, and global physical self-concept. Our path model suggested that the mastery-approach goal, intrinsic motivation, and global self-esteem partially mediated the relationship between global physical self-concept and flourishing. Our findings help to inform alternative approaches for cultivating exercisers’ flourishing. However, knowledge on how to support and develop flourishing is still under-researched in sport and exercise settings.

Physical self-perception and Personality Traits among Women with Psychoactive Substance Abuse Compared to Normal Individuals

Introduction: Regarding to the role of physical self-perception and personality traits in abuse of psychoactivesubstance among women, this study aimed to compare the concept of physical self-perception and personalitytraits among psychoactive substance abusers and normal individuals.Materials and Methods: In this causal-comparative study, 60 women (30 psychoactive substance abusers,30 normal cases) referred to substance abuse treatment centers in Mashhad city (the second big-city of Iran)were selected in convenient sampling method. The Physical Self-Description Questionnaire (PSDQ) andNEO-Five Factor Test (Short Form) were performed. Data were analyzed using multivariate analysis andtwo independent means tests.Results: Multivariate analysis revealed that women with psychoactive substance abuse have higher scoresin neuroticism and lower scores in agreeableness, accountability and extraversion than normal women. Thecomparison of two independent means also showed that there is a significant difference between physicalself-perception in normal and abusers, so that normal women have better physical self-perception.Conclusion: The results confirm that physical self-perception and personality traits play an important rolein involvement in substance abuse.

The relationship between actual and self-perceived physical fitness in adolescence

The purpose of this study was to assess the relationship between physical self-concept and actual indicators of physical fitness in early and mid-adolescence. Physical self-concept plays a significant role in adolescence, as this phase of life is characterised by many physical, mental, and emotional changes. A total of 427 Slovenian boys and girls from two age groups (early and middle adolescence) were studied. Physical self-concept was assessed with the Slovenian version of Physical Self-Description Questionnaire, while the Sports-educational Chart was used to measure physical fitness. The results showed that the older group scored better on all measures of physical fitness, except for general endurance. In terms of age-related differences in physical self-concept, older adolescents showed poorer physical perceptions of their strength and flexibility and higher global self-esteem compared to their younger peers. Correlation analysis showed that physical self-concept and actual indicators of physical fitness were related, despite incomplete overlap between psychological dimensions and objective measures. The obtained results can be transferred to physical education, as the development of a positive physical self-concept is one of the most important educational goals.

Psychometric properties and construct validity of PLAYself: a self-reported measure of physical literacy for children and youth

PLAYself is a tool designed for self-description of physical literacy in children and youth. We examined the tool using both the Rasch model and Classical Test Theory to explore its psychometric properties. A random selection of 300 children aged 8-14 years (47.3% female) from a dataset of 8513 Canadian children were involved in the Rasch analysis. The 3 subscales of the measure demonstrated good fit to the Rasch model, satisfying requirements of unidimensionality, having good fit statistics (item and person fit residuals = -0.17-1.47) and internal reliability (Person Separation Index = 0.70-0.82), and a lack of item bias and problematic local dependency. In a separate comparable sample, 297 children also aged 8-14 years (53.9% female) completed the PLAYfun, Physical Self-Description Questionnaire (PSDQ), Physical Activities Measure-Revised (MPAM-R), a physical activity inventory (PLAYinventory), and repeated the PLAYself 7 days later. The tests with this sample confirmed test-retest reliability (intraclass correlation coefficient = 0.81-0.84), and convergent and construct validity consistent with contemporary physical literacy definitions. Overall, the PLAYself demonstrated robust psychometric properties, and is recommended for researchers and practitioners who are interested in assessing self-reported physical literacy. Novelty: The PLAYself is a self-reported measure of physical literacy This study validates the measure using the Rasch model and classical test theory The PLAYself was found to have strong psychometric properties.

Perceived and Measured Physical Fitness of Police Students.

The physical fitness of police officers needs to support good health and physical performance. Physical fitness comprises a considerable amount of training for police students who are to become police officers. However, to what degree police students are able to perceive their fitness level and differentiate between health-related and performance-related physical fitness is unknown. Therefore, the first aim of this study was to investigate the possibility of differentiation between health-related and performance-related physical fitness using physical self-concept and measured indicators of physical fitness. The second aim of this study was to investigate the association between components of physical self-concept and measured indicators of physical fitness of police students. The sample of 177 police students of both sexes (98 males and 79 females) completed a 40-item physical self-description questionnaire and their physical abilities were assessed for handgrip strength, standing long jump, 30 s sit-ups, and 12-min running. Principal component analysis established health-related and performance-related physical fitness from both perceived and measured physical fitness measures. Correlation analysis revealed a significant relationship between the perceived and measured physical fitness. Results suggest small to moderate ability to recognize the level of certain physical abilities, indicating the association between psychological mechanisms and biological functioning.

Composición e invarianza factorial de la versión corta del Physical Self Description Questionnaire en adolescentes mexicanos

El objetivo de esta investigación fue analizar las propiedades psicométricas propuestas por Marsh, Martin y Jackson (2010) para la versión corta del Physical Self Description Questionnaire (PSDQ-S). La muestra total fue de 915 adolescentes mexicanos 400 deportistas y 515 no deportistas, con edades comprendidas entre 11-15 años (M = 12.33; DE = 1.43). La estructura factorial del cuestionario se analizó mediante análisis factoriales confirmatorios. Los análisis, muestran que una estructura de nueve factores (actividad física, apariencia, grasa corporal, coordinación, resistencia, flexibilidad, salud, competencia deportiva y fuerza) es viable y adecuada tanto para la muestra total (GFI .964; RMSEA .030; CFI .981) como para las poblaciones de adolescentes mexicanos deportistas (GFI .921; RMSEA .049; CFI .946) y no deportistas (GFI .943 y RMSEA .049; CFI .970). La estructura de nueve factores, atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Por otro lado, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes de acuerdo a la variable práctica deportiva; sin embargo, existen diferencias significativas a favor de los deportistas en cuanto a su autoconcepto físico: actividad física (-1.243, p &lt;0.001), grasa corporal (-0.212, p &lt;0.05), coordinación (-0.765, p &lt;0.001), resistencia (-0.882, p &lt;0.001), flexibilidad (-0.427, p &lt;0.001), salud (-0.172, p &lt;0.05), competencia deportiva (-1.026, p &lt;0.001) y fuerza (-0.614, p &lt;0.001). En conclusión, el PSDQ-S puede ser una herramienta útil para avanzar en el estudio de los factores que afectan al autoconcepto físico. The aim of this research was to analyze the psychometric properties proposed by Marsh et al. (2010) for the Physical Self Description Questionnaire (PSDQ-S). The total sample has been composed by 915 Mexican adolescents, 400 athletes and 515 non-athletes, with ages from 11 to 15 years (M = 12.31, SD = 1.43). The factor structure of questionnaire has been analized through the confirmatory factor analysis. This analysis shows that a nine factors structure is viable and adequate for the total sample (GFI .964; RMSEA .030; CFI .981) and the populations of athletes (GFI .921; RMSEA .049; CFI .946) and non-athletes (GFI .943 y RMSEA .049; CFI .970). The nine factors structure (physical activity, appearance, body fat, coordination, endurance, flexibility, health, sport competence, and strength), according to statistical and substantive criteria, has shown adequate indicators of reliability and validity adjustment. On the other hand, the factorial structure, the factorial loads and the intercepts are considered invariant according to the variable sports practice; however, there are differences between athletes and non-athletes in favor of athletes in terms of their physical self-concept: physical activity (-1,243, p &lt;0.001), body fat (-0.212, p &lt;0.05), coordination (-0.765, p &lt;0.001), endurance (-0.882, p &lt;0.001), flexibility (-0.427, p &lt;0.001 ), health (-0.172, p &lt;0.05), sports competition (-1.026, p &lt;0.001) and strength (-0.614, p &lt;0.001). In conclusion, the PSDQ-S can be a useful tool to advance in the study of the factors that affect the physical self-concept. O principal objetivo deste estudo foi analizar as propiedades psicométricas propostas por Marsh et al. (2010) para a versão curta de Physical Self Description Questionnaire (PSDQ-S). Amostra total foi de 915 adolescentes mexicanos 400 atletas e 515 não- atletas com idades entre 11-15 anos (M = 12.33; DE = 1.43). A estrutura fatorial foi analisado com anàlise fatorial confirmatòria. Os analises mostran a estrutura do nove fatores (atividade física, aparência, gordura corporal, coordenação, resistencia, flexibidade, saúde, competencia esportiva e força) e factível e adequado para a mostra total (GFI .964; RMSEA .030; CFI .981) e para ambas as populações, atletas (GFI .921; RMSEA .049; CFI .946) e não atletas (GFI .943 y RMSEA .049; CFI .970). A estrutura de nove fatores, em resposta a criterios estatísticos e materiais tem mostrado indicadores de ajuste adequados de confiabilidade e validade. Além disso a estrutura de fatores, cargas fatoriais e intercepto são considerados invariantes em variável prativa esportiva, porém diferenças entre atletas e não atletas forom encontrados em favor dos atletas em termos de seu autoconceito físico: atividade física (-1,243, p &lt;0,001), gordura corporal (-0,212, p &lt;0,05), coordenação (-0,765, p &lt;0,001), resistência (-0,882, p &lt;0,001), flexibilidade (-0,427, p &lt;0,001 ), saúde (-0,172, p &lt;0,05), competição esportiva (-1,026, p &lt;0,001) e força (-0,614, p &lt;0,001). Em conclusão, el PSDQ-S pode ser uma ferramenta útil para avançar no estudo dos fatores que afetam o autoconceito físico.
