Objective: This study proposed an innovative approach to simplify the multiple psychological scales for children and adolescents by integrating statistical methods and item reflection theory into a structural equation model.
Method: First, we developed a psychological scale for adolescents to replace the existing scales optimized for adults with the Delphi method. Second, we reduced the number of items in the current group of scales.
Result: We built up a psychological scale for adolescents that comprehensively reflects their psychological characteristics in terms of mental state, behavioral status, emotion & feeling, relationship, and environmental adaptation. We also simplified this psychological scale and improved its reliability and validity.
