The study sample consists of adolescents aged 15 to 18 in Turkey. With purposive sampling, 2834 adolescents with different socioeconomic and cultural characteristics from three Turkish cities (i.e., Ankara, Sivas, and Mugla) were selected. Both a personal data form and the Adolescent Health and Development Questionnaire (AHDQ) were used. For data analysis, participants' demographic characteristics and average scores according to scale frequency and percentage distribution were used. In order to test the developed model, a path analysis with latent variables method, which puts forth both mediation and direct effects, was implemented.
