“…Furthermore, research has shown that males are more motivated to engage in team sports (Carnahan et al, 2018) and PA is tied to masculine norms and ideals (Carnahan et al, 2018;Courtenay, 2000). This may be particularly relevant to the Jamaican context where masculinity is emphasised (Ricketts et al, 2020). Unfortunately, details on the motives and relevance behind adolescents' engagement in these activities, whether competitive or leisure activity, along with any positive effects associated with team sports, were not explored in this study.…”

E xcessive physical activity (PA) has been linked to increased risk for disordered eating behaviours and eating disorders.This study investigates the relationship between PA and disordered eating behaviours and attitudes (DEBAs) among Jamaican adolescents. This cross-sectional study included 521 adolescents, 12-19 years. Anthropometric measurements were collected, and adolescents completed questionnaires on disordered eating behaviours (EAT-26), physical activity, self-esteem and affect. Associations were assessed using sex-specific mixed-effect linear and logistic regression models. Participants reported exercising an average of 3 days per week. Adolescents who exercised for a longer duration had greater odds of having elevated EAT-26 scores (at least 1 hour-OR = 2.04; 95% CI = 1.03, 4.06; p = .042), while a higher exercise frequency among males (3-5 days per week) was protective against DEBAs (OR 0.38; 95% CI = 0.16, 0.88; p = .025). Female adolescents reported higher prevalence of elevated EAT-26 scores than males (p < .01). Increased negative affect increased odds of an elevated EAT-26 score. Exercise duration and frequency play a role in disordered eating behaviours in Jamaican adolescents and vary by gender. Our findings have implications for weight management interventions and policies, encouraging healthcare providers to monitor PA levels as well as negative affect in adolescents who display disordered eating behaviours.

“…Since its development, the DMS has been translated in different languages and adapted to different countries and languages, including Spanish [ 23 , 24 ], Italian [ 25 ], German [ 26 ], Portuguese [ 27 ], Romanian [ 28 ], Turkish [ 29 ], Persian [ 30 ], Lithuanian [ 31 ], Malay [ 32 ], Brazilian [ 33 ], and Chinese [ 34 ]. The DMS has also been validated in various populations, including university students men [ 20 , 28 ], young adult women [ 35 ], sexual minority men and women [ 36 , 37 ], weightlifters [ 38 ], and bodybuilders [ 30 ]. All these versions provided empirical support to the good psychometric characteristics of the DMS, by showing an adequate internal consistency (Cronbach’s alpha > 0.70) and confirming its original 2-factor structure (attitudes and behaviors) [ 39 ].…”

“…The very limited attempts to validate the measure in women samples (e.g., [ 22 , 40 , 41 ]) failed to support the factor model suggested in the parent version and consistently described in men; thus questioning the factorial validity of the scale and its invariance across gender groups. Other psychometric characteristics have also been supported, including test–retest reliability [ 3 , 26 , 31 ], and good convergent validity as evidenced through significant correlations with other relevant constructs (e.g., body image dissatisfaction [ 23 , 42 ], self-esteem [ 1 , 20 , 31 , 32 ], muscle discrepancy [ 32 ], BMI [ 31 , 32 ], disordered eating attitudes/behaviors [ 1 , 20 , 31 ], and psychological distress [ 1 , 38 ]).…”

Background After the original 15-item Drive for Muscularity Scale developed by McCreary et al. in 2004, a more theoretically based scale that replicates the original DMS subscales with a better conceptual clarity and a shorter number of items, i.e., the DMS-9, has recently been developed by Chaba et al. in 2018. We sought to contribute to the literature especially under the Arab context, by investigating the psychometric properties of an Arabic translation of the DMS-9 in a sample of Arabic-speaking Lebanese university students of both genders. Methods University students (N = 402; 55.2% females) from multiple universities in Lebanon were invited to fill the survey in this cross-sectional designed study (December 2022 and January 2023). Our sample was chosen using the snowball technique; a soft copy of the questionnaire was created using google forms software, and an online approach was conceived to proceed with the data collection. Results Using an Exploratory Factor Analysis-to- Confirmatory Factor Analysis strategy, we found that the original two-factor model of the DMS proposed in the parent study was adequately replicated in our sample. The two DMS-9 factor scores showed very good McDonald’s omega values (ω > 0.8). Findings also showed that gender invariance was achieved at the configural, metric, and scalar levels. Additionally, drive for muscularity scores correlated in the expected way with other study variables, providing support for the convergent and divergent validity of the Arabic DMS-9. Specifically, we found that greater drive for muscularity attitudes and behaviors significantly correlated with more severe muscle dysmorphic symptoms, inappropriate eating attitudes, muscle bias internalization, and lower body appreciation. Conclusion Findings preliminarily suggest that the Arabic DMS-9 is psychometrically sound and suitable tool to assess the drive for muscularity construct among Arabic-speaking community adults. Making the Arabic DMS-9 available will hopefully benefit the scientific community working in Arab settings, promote local and international research in this area, and offer descriptive data on how drive for muscularity may interfere with health indicators in the general Arab population.
