Reliability and construct validity of five life domains in the adolescent drug abuse diagnosis instrument in a sample of Swedish adolescent girls in special residential care

摘要

Aim: This cross-sectional study investigates the psychometric properties of the Swedish edition of the Adolescent Drug Abuse Diagnosis (ADAD), and specifically examines the internal consistency and construct validity of five life domains reported by female adolescents in special residential care in Sweden (N ? 780; Mage ? 16 years old). Methods: Principal component analysis and entropy-based analysis were used to test construct validity. Conclusion: Results indicate that ADAD may be able to reliably distinguish between areas that are important targets for intervention.
