Reliability and Validity Analyses of the Self-Management Questionnaire

Abstract

The authors developed a parent-report measure to enhance findings for diagnoses and evaluations, and therefore, improve on the assessments currently being widely used for this purpose. Data were gathered on 322 clients (4–18 years old) seeking treatment at a private practice setting. Factor analysis revealed 18 subscales. Scores were internally consistent and distinct from other subscales. In addition, the questionnaire showed good diagnostic utility for depression, Oppositional Defiant Disorder (ODD), and Pervasive Developmental Disorder (PDD). This study provides sufficient evidence of the reliability and validity of the Self-Management Questionnaire (SMQ) to recommend its use for skills and needs assessment with children and adolescents.
