Construct Validity and Reliability of the Chinese Version Personal Adjustment and Role Skills Scale III for Adolescents With Chronic Disease

A valid and reliable scale to evaluate psychosocial adjustment in adolescents with chronic disease is prudent for improving their health outcome. This study aimed to develop a Chinese version Personal Adjustment and Role Skills Scale III for Adolescents (C-PARSIII-A) with chronic disease and to examine its construct validity and reliability. A cross-sectional design was conducted. A total of 145 participants were enrolled from a hospital in Taiwan. Content validity, exploratory factor analysis, and corrected item-total correlations were used to explore a factor structure with appropriate items in a C-PARSIII-A. Confirmatory factor analysis was conducted to confirm its factor structure. Cronbach's α and test-retest reliability were performed to examine the reliability. The 18-item C-PARSIII-A with six inter-correlated factors was developed. The standardized factor loadings of each item on its corresponding factor were statistically significant and higher than 0.50; composite reliability and average variance extracted were higher than 0.70 and 0.50 respectively. The correlation coefficients among the six factors in the C-PARSIII-A ranged from 0.10 to 0.84. Cronbach α and test–retest reliability of the C-PARSIII-A were 0.86 and 0.92 respectively. The six-factor 18-item C-PARSIII-A is supported by sufficient empirical evidence for construct validity and reliability to assess the psychosocial adjustment of adolescents with chronic disease. Nurses can use the C-PARSIII-A to perform assessment and follow-up on the psychosocial adjustment of adolescents with chronic disease, as well as develop interventions. •The C-PARSIII-A is a reliable and valid scale.•The C-PARSIII-A consists of six factors and 18 items.•Nurses can use the C-PARSIII-A to test adjustment of adolescents with chronic disease.
