Structural validity and internal consistency of the Client Satisfaction Questionnaire-8 among parents of children with ADHD: a cross-sectional study

Abstract: This study aimed to examine the structural validity and internal consistency of the eight-item Client Satisfaction Questionnaire (CSQ-8) among parents of children diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD), attending and evaluating a psychoeducational programme. Based on previous research, we hypothesised that the CSQ-8 would demonstrate a unidimensional factor structure and high internal consistency in this population.
