An Evaluation of the Psychometric Properties of the Universal Nonverbal Inventory of Personality

The Universal Nonverbal Inventory of Personality (UNIP; McCallum, in preparation), which is designed to measure psychopathological maladjustment of children and adolescents who have limited or no English language proficiency, and the Behavior Assessment System for Children-Second Edition Self-Report (BASC-II; Reynolds & Kamphaus, 2004) were administered to 100 participants to establish reliability and concurrent validity. Some of the UNIP scales yielded adequate reliability: Anxiety (.85), Depression (.84), Atypicality (.78), Academic Problems (.77), Attention Deficit Hyperactivity Disorder (.75), and Conduct Problems (.73); others possess only marginal reliability: Social Maladjustment (.64) and Consistency (.54) scales. Correlation coefficients between the UNIP and the BASC-II support the validity of the UNIP Depression, Anxiety, Attention Deficit Hyperactivity Disorder, Academic Problems, and Conduct Problems scales. Results provide only marginal support for the concurrent validity of the UNIP Social Maladjustment and Atypicality scales. The utility of the UNIP for clinicians and the need for future investigations are discussed.
