Objectives:
To translate the Children and Adolescents Participation in Decision-Making Questionnaire (CAP-DMQ) into Greek and to assess its psychometric characteristics.
Methods:
This study used a cross-sectional approach with a convenience sample of 300 students aged 12 to 16 from four high schools and two middle schools in Larissa, Greece, achieving a 100% response rate. Data were gathered over four months, from January to April 2025. Statistical analyses were performed utilizing SPSS version 29. Exploratory Factor Analysis was employed to examine the factor structure of the Greek adaptation of the CAP-DMQ.
Results:
The analysis revealed a one-factor structure of the CAP-DMQ, based on Kaiser's criterion (eigenvalue > 1), which accounted for 34.2% of the total variance. All items had factor loadings greater than 0.40 on the single factor. The highest loading was observed for item 7, while the lowest was for item 8. The Cronbach's alpha coefficient for the 10 items was 0.862, and McDonald's ω was 0.865, both indicating good internal consistency. The mean CAP-DMQ score was 1.497 (SD = 0.145), reflecting a high level of participation in decision-making.
Conclusions:
The results show that the Greek version of the CAP-DMQ has a single-factor structure and demonstrates strong internal consistency reliability. This version serves as a concise and reliable instrument for evaluating the involvement of children and adolescents in decision-making among Greek-speaking individuals.
