Objective: This study aims to evaluate the psychometric properties of the CBCL 1.5-5 Parent Scale's seven subscales (Emotional Reactivity, Anxiety/Depression, Withdrawal, Somatic Complaints, Sleep Problems, Attention Problems, and Aggression Issues).
Methods: The study involved 172 parents of children aged 3-6 with Autism Spectrum Disorder (ASD). Data collected from parents were analyzed using Confirmatory Factor Analysis (CFA) in R-Studio. The unidimensionality of the seven subscales was tested, and items with factor loadings below 0.20 were excluded from the analysis. Reliability analyses were conducted using Cronbach’s alpha and Ordinal alpha.
Results: CFA results indicated that most subscales were unidimensional and had valid structures. Emotional Reactivity, Anxiety/Depression, Social Withdrawal, and Attention Problems showed good model fit. However, the Aggression and Sleep Problems subscales showed lower model fit (CFI = 0.757, TLI = 0.720 / CFI = 0.876, TLI = 0.794). Reliability analyses showed adequate reliability for most subscales (Cronbach’s alpha: 0.62-0.80), but low reliability for Somatic Complaints (Cronbach’s alpha: 0.23-0.29). The Partial Credit Model (PCM) showed stable convergence after four iterations with excellent reliability scores (WLE = 0.869, EAP = 0.871). Item analysis showed well-distributed difficulty levels and no disordered thresholds, though items Q90 and Q18 exhibited high thresholds, suggesting the need for further evaluation.
Conclusions: This study suggests that the CBCL 1.5-5 Parent Scale is a valid and reliable psychometric tool for assessing behavioral problems in children with ASD. However, improvements are needed for the Aggression and Somatic Complaints subscales. The findings support the scale’s effectiveness in assessing child behavioral issues based on parent ratings.
