Development, Implementation, and Evaluation of the HADAS Program for the Prevention of Eating Disorders in Adolescent Female Athletes, Coaches, and Families. (The HADAS)

1 августа 2026 г. обновлено: Eva Maria Leon Zarceño, Universidad Miguel Hernandez de Elche

A Program for the Prevention of ED in Adolescent Female Athletes, the HADAS: Protocol for a Randomized Controlled Trial Study

Adolescent female athletes in aesthetic sports disciplines (such as rhythmic gymnastics, artistic gymnastics, synchronized swimming, and figure skating) face a complex interaction between general sociocultural beauty pressures and sport-specific aesthetic demands (e.g., the 'slim to win' culture and weight-focused performance expectations). These combined pressures significantly increase their risk of developing body dissatisfaction and eating disorders (EDs). To address these systemic vulnerabilities, the HADAS Program (Habits, Eating, Sports, Adolescents, and Health) was developed as a multi-level, synchronized psychoeducational intervention designed to target the complete "sports triangle": adolescent female athletes, their technical coaches, and their immediate family members. The primary objective of this cluster randomized controlled trial (cluster RCT) is to evaluate the efficacy of the HADAS Program in reducing eating disorder risk (EAT-26) and body image dissatisfaction (BSQ-34) among competitive adolescent female athletes aged 12 to 16 years. Sports clubs are randomly assigned to either the Experimental Group (receiving the HADAS intervention) or a Waitlist Control Group (maintaining standard training). The program includes 5 interactive group sessions for athletes, 4 reflective workshops for coaches, and 2 structured sessions for family members, all supported by cohort-specific workbooks. Outcomes are evaluated across four longitudinal time points: Baseline (T0), Immediate Post-intervention (T1), 6-month Follow-up (T2), and 12-month Follow-up (T3).

It measures athletes' perceptions of their coach's controlling interpersonal style across 15 items rated on a 7-point Likert scale ranging from 1 ("strongly disagree") to 7 ("strongly agree"). The scale assesses four subscales: Controlling Use of Rewards (4 items), Negative Conditional Regard (4 items), Intimidation (4 items), and Excessive Personal Control (3 items). Total scores range from 15 to 105, where higher scores reflect higher perceived controlling behaviors from the coach (a worse outcome).
Baseline (T0), Immediate Post-intervention (T1), 6-month Follow-up (T2), and 12-month Follow-up (T3).
Leadership style in sport
Временное ограничение: Baseline (T0), Immediate Post-intervention (T1), 6-month Follow-up (T2), and 12-month Follow-up (T3).
Evaluated using the Leadership Scale for Sports (LSS; Chelladurai & Saleh, 1980; Spanish validation by Crespo et al., 1994). It assesses perceived coaching leadership behaviors across 31 items rated on a 5-point Likert scale ranging from 1 ("never") to 5 ("always"). The Spanish adaptation measures 4 dimensions: Relationship-Oriented Behavior (13 items), Task-Oriented Behavior (10 items), Democratic Behavior (4 items), and Autocratic Behavior (4 items). Dimension mean scores range from 1 to 5, where higher scores in Relationship-Oriented, Task-Oriented, and Democratic behaviors reflect more supportive and adaptive leadership styles (a better outcome).

Coach Eating Disorder Literacy and Warning Signs Knowledge
Временное ограничение: Baseline (T0), Immediate Post-intervention (T1), 6-month Follow-up (T2), and 12-month Follow-up (T3).
Evaluated using the ad hoc Coach Eating Disorder Knowledge Questionnaire, created specifically for the HADAS Program by its research group to evaluate program-specific learning objectives. The instrument was developed and validated via a four-stage process (item generation, expert panel review, scoring design, and pilot testing). It assesses sports-specific eating disorder (ED) literacy across 25 items structured in 5 core dimensions: (1) General multi-causal etiology (items 1-6); (2) Identification of behavioral/emotional warning signs in sports contexts (items 7-11); (3) Risk and protective factors in competitive environments (items 12-16); (4) Consequences on physical health and performance (items 17-20); and (5) Early detection and intervention protocols (items 21-25). Items use a True/False/I Don't Know (1 point for correct responses; 0 points for others). Total scores range from 0 to 25, where higher scores indicate higher sports-specific ED literacy and detection competence
Baseline (T0), Immediate Post-intervention (T1), 6-month Follow-up (T2), and 12-month Follow-up (T3).
