Further development of the 12-item EDEQS: identifying a cut-off for screening purposes

Background: The Eating Disorder Examination – Questionnaire Short (EDE-QS) was developed as a 12-item versionof the Eating Disorder Examination Questionnaire (EDE-Q) with a 4-point response scale that assesses eatingdisorder (ED) symptoms over the preceding 7 days. It has demonstrated good psychometric properties at initialtesting. The purpose of this brief report is to determine a threshold score that could be used in screening forprobable ED cases in community settings.Methods: Data collected from Gideon et al. (2016) were re-analyzed. In their study, 559 participants (80.86% female;9.66% self-reported ED diagnosis) completed the EDE-Q, EDE-QS, SCOFF, and Clinical Impairment Assessment (CIA).Discriminatory power was compared between ED instruments using receiver operating characteristic (ROC) curveanalyses.Results: A score of 15 emerged as the threshold that ensured the best trade-off between sensitivity (.83) andspecificity (.85), and good positive predictive value (.37) for the EDE-QS, with discriminatory power comparable toother ED instruments.Conclusion: The EDE-QS appears to be an instrument with good discriminatory power that could be used for EDscreening purposes

The importance of fundamental motor skills in identifying differences in performance levels of U10 soccer players

This study examined the differences in fundamental motor skills (FMSs) and specific conditioning capacities (SCCs) between a coach’s classification of first team (FT) and second team (ST) U10 soccer players and examined the most important qualities based on how the coach differentiates them. The FT (n = 12; Mage = 9.72 ± 0.41) and ST (n = 11; Mage = 9.57 ± 0.41) soccer players were assessed using the Test of Gross Motor Development-2, standing long jump, sit and reach, diverse sprints, and the 20 m multistage fitness test (MSFT). The coach’s subjective evaluation of players was obtained using a questionnaire. No significant differences existed between the FT and ST in any variables (p > 0.05). However, large and moderate effect sizes were present in favour of the FT group in locomotor skills (d = 0.82 (0.08, 1.51)), gross motor quotient (d = 0.73 (0.00, 1.41)), height (d = 0.61 (−0.12, 1.29)), MSFT (d = 0.58 (−0.14, 1.25)), and maximum oxygen uptake (VO2max) (d = 0.55 (−0.17, 1.22)). Furthermore, the coach perceived the FT group as having greater technical and tactical qualities relative to ST players. This suggests that it might be more relevant for players of this age to develop good FMS connected to technical skills, before focusing on SCC. Therefore, it might be beneficial for soccer coaches to emphasize the development of FMSs due to their potential to identify talented young soccer players and because they underpin the technical soccer skills that are required for future soccer success

Identifying components of drive for muscularity and leanness associated with core body image disturbance: a network analysis

Public Significance Statement Desire to obtain muscular and desire to obtain lean body are considered risk factors for body image disturbance and, in turn, eating disorder development, but typically used scales also capture aspects common in healthy individuals. By using network analysis in community adolescents, we observed both positive and negative associations between drive for muscularity, leanness, and body image disturbance, which suggests that these concepts might need to be assessed as multifaceted rather than uniform.Alongside thin ideals, internalizing muscular and/or lean body ideals is associated with eating disorder (ED) symptomatology, especially among males. However, assessment of drive for muscularity (DM) and drive for leanness (DL) also captures attitudes and behaviors that are normative in the general population. The aim of this study was to identify components of DM and DL that are independently linked to core body image disturbance in EDs-shape/weight dissatisfaction, overvaluation ,and fear of weight gain-in community adolescents using network analysis. A representative sample of 4,975 Australian adolescents (53% females, M-age = 14.92) from Wave 1 of the EveryBODY study was included in the analyses. We estimated regularized and unregularized networks, identified communities of items, estimated bridge centrality between communities, and explored sex differences in network structure and connectivity with a Network Comparison Test. Results showed that items "feeling better about oneself if having a lean body" and "wishing to be muscular" had the highest bridge centralities, and network structures of male and females did not significantly differ. Importantly, some components of DM were negatively associated with body image disturbance. These findings suggest that, when investigating the role of DL and DM in EDs, it would be useful to further assess these constructs as multifaceted since relationships between these phenomena are likely more nuanced than previously speculated. Development and subsequent use of instruments for certain behaviors and/or attitudes more specifically associated with body image disturbance might be more informative than somewhat artificially confined focus on either thinness, leanness, or muscularity.Stress and Psychopatholog
