Validity and Reliability of Three Rating Scales to Assess Practitioners’ Skills to Conduct Collaborative, Strength-Based, Systemic Work in Family-Based Services

Abstract

This study analyzed the reliability and validity of three rating scales designed to assess practitioners’ skills in conducting systemic, collaborative, and strength-based assessments and interventions with multi-challenged families in family-based community services. The three scales, which assess reception and assessment skills, basic skills, and skills to support change, revealed good psychometric properties considering their construct validity, internal consistency, and inter-rater agreement. The results are discussed considering future research and possible applications of the scales in research and practice.
