Validating the Factor Structure of the Psychosocial Assessment Tool Using Internet-Based Data

The Psychosocial Assessment Tool (PAT) is a well-validated, brief screener of family psychosocial risk. Since 2014 a web-based version of the PAT (WebPAT) has been available for use by clinicians and researchers, but the psychometric properties have not been examined. The objective of this article was to examine the factor structure and internal consistency of the WebPAT, which was administered to caregivers of youth with cancer.

The WebPAT was administered to 1,252 caregivers of youth with cancer across 29 institutions. Confirmatory factor analysis (CFA) was used to examine the factor structure of the WebPAT. Internal consistencies of the total and subscale scores were examined via the Kuder-Richardson 20 coefficient. The distribution of total PAT score across the three risk categories of the Pediatric Psychosocial Preventative Health Model (PPPHM) was also examined.

The CFA supported the original seven-factor structure of the PAT (Family Structure, Social Support, Child Problems, Sibling Problems, Family Problems, Stress Reactions, and Family Beliefs). Internal consistencies were strong for the total PAT score and four subscales (Social Support, Child Problems, Sibling Problems, and Family Problems). The distribution of total PAT scores across PPPHM risk categories was consistent with prior research.

The WebPAT is a psychometrically sound screener of psychosocial risk in families of youth with cancer. Healthcare providers can use the WebPAT to assess families' psychosocial risk and guide the provision of psychosocial care. Future research should evaluate the implementation of the PAT and identify barriers and facilitators to implementation.
