title: Adaptation and validation of a self-report measure to evaluate substance use among Sri Lankan adolescents.
abstract: This study translated and validated the model Student Questionnaire (SQ) among 13- to 18-year-old Sri Lankan adolescents. A systematic procedure was followed to translate the SQ into Sinhala language. The Sinhala version was titled Adolescent Substance Use Student Questionnaire (ASUSQ). A Delphi process was conducted to evaluate consensual validity of ASUSQ. Test-retest study (N = 120) ensured reliability. Contrasted group technique study (N = 200) among users and nonusers established construct validity. Data collection instruments were SQ, its Sinhala version, structured-interview schedule, and focus group discussion guide. Sinhala-speaking students were randomly selected from schools in a semi-urban area. Applicability of the ASUSQ and further research are discussed. The study's limitations are noted.
