Perceived weight-related victimization and physical activity outcomes among adolescents with overweight and obesity: Indirect role of perceived physical abilities and fear of enacted stigma

Objectives Recently, victimization has been shown to be negatively related to physical activity among adolescents with overweight or obesity. However, research on this relation remains scarce and plagued by multiple limitations. The objectives of this study were twofold. First, we wanted to replicate and extend previous research among adolescents with overweight and obesity by examining the relations between perceived weight-related victimization in school-based physical activity and students’ perceived physical education performance or involvement in physical activity outside school. Second, we wanted to investigate the indirect role of perceived physical abilities and fear of enacted stigma on these relations. Design A cross-sectional design was used. Method A sample of 144 secondary school students with overweight and obesity participated in this study. Results Perceived physical abilities were found to play a significant and negative indirect role in the relations between perceived weight-related victimization and students’ perceived physical education performance or involvement in physical activity outside school. When sex and age were controlled for, these relations remained significant. The mediating role of fear of enacted stigma was non-significant. Conclusions Schools should implement policies that do not tolerate weight-related victimization of students and that promote a safe and positive climate during physical activities. Moreover, a personalized approach providing choices and encouragements would help youth gain confidence in their abilities to perform or engage in physical activities

Cross-validation of the short form of the physical self-inventory (PSi-S) using exploratory structural equation modeling (ESEM)

Objectives: In a review of physical self-concept instruments Marsh and Cheng (in press) noted that the short version (18 item) of the physical self-inventory (PSI-S) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples and to investigate the reasons for the elevated correlations observed between the six PSI-S subscales. Design and Method: A sample of sample 2029 French adolescents completed the PSI-S and their answers were analyzed with exploratory structural equation modeling (ESEM). Results: The results show that the PSI-S ESEM measurement model is robust and fully invariant across subgroups of students formed on the basis of gender, weight categories, age categories, and ethnicity. The results also confirm the convergent validity and reliability of the PSI-S subscales. Most importantly, the ESEM model results in importantly deflated latent factor correlations and suggest that the previously reported inflated correlations may have been due to the fact that traditional confirmatory factor analytic (CFA) models arbitrarily constrain all cross-loadings to zero. In addition, the ESEM model reveals that the negatively worded items from the PSI-S may be suboptimal, a result that was not obvious from the CFA results. Conclusion: The obtained results clearly confirm the robustness of the psychometric properties of the PSI-S and the usefulness of ESEM for more detailed analyses of measurement scale psychometric properties. Reformulations for the negatively worded items are proposed and directions for future studies of the PSI-S are noted

Cross-validation of the very short form of the Physical Self-Inventory (PSI-VS) : invariance across genders, age groups, ethnicities and weight statuses

In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and diversified samples. The present study was designed to answer these questions based on a sample of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales

The Center for Epidemiologic Studies Depression Scale :Factor validity and reliability in a French sample of adolescents with intellectual Disability

The purpose of this study was to test the factor validity and reliability of the Center for Epidemiologic Studies Depression Scale (CES-D) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total sample of 189 adolescents (121 boys and 68 girls), aged between 12 and 18 years old, with mild to moderate ID were involved in two studies. In study 1, the content, phrasing and answering format of the CES-D were adapted for adolescents with ID. This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed and their psychometric properties were verified in study 2. The results provided support for the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale

The intellectual disability version of the very short form of the physical self-inventory (PSi-VS-ID) :Cross-validation and measurement invariance across gender, weight, age and intellectual disability level

Recently Maïano, Bégarie, Morin, and Ninot (2009) developed and validated an intellectual disability (ID) version of the very short form of the physical self-inventory (PSI-VS-ID). In a recent review of the various physical self-concept instruments Marsh and Cheng (in press) noted that the short and very short versions of the French PSI represent an important contribution to applied research but that further research was needed to investigate the robustness of their psychometric properties in new and diversified samples. Thus, this study is specifically designed to investigate the robustness of the PSI-VS-ID psychometric properties in a new independent sample of 248 adolescents and young adults with ID. In particular, tests of measurement invariance were conducted across the present sample and the original sample from Maïano et al. (2009) study in order to more precisely assess the degree of replication of the results. Overall, results from a series of confirmatory factor analyses of the PSI-VS-ID provided support for its: (i) factorial validity and reliability; (ii) factorial invariance across gender and weight status; (iii) partial (strict or strong) factorial invariance across age, ID level and samples; and (iv) latent mean differences across gender, weight status and ID level groups

Assessment of physical self-concept in adolescents with intellectual disability: Content and factor validity of the very short form of the physical self-inventory

The purpose of this study was to test the factor validity and reliability of the Very Short Form of the Physical Self-Inventory- (PSI-VSF) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total of 362 ID adolescents were involved in two studies. In Study 1, the content and format scale response of the PSI-VSF were adapted for adolescents with ID. This instrument was thus renamed PSI-VSF-ID and two versions with two alternative responses scales format, were developed: Likert and graphical. In Study 2, results provided support for: (1) the factorial validity and reliability; and (2) factorial invariance across gender, age, type of school placement and ID level of the PSI-VSF-ID associated with a graphical response scale format
