Inter-Rater Reliability of the Pizzi Health and Wellness Assessment (PHWA).

The objective of this study is to determine the inter-rater reliability of the Pizzi Health and Wellness Assessment (PHWA) by comparing the consistency in scores between clients and their caregivers in the following areas of participation: social, physical, family, occupational, mental/emotional, and spiritual. A retrospective inter-rater correlational design was used to analyze the agreement of scores from a convenience sample consisting of two groups: clients with disabilities (n = 19) and their healthy caregivers (n = 19). Inter-rater reliability was calculated using correlations for the PHWA as a whole, and for the current level of participation and wishing to improve participation subsections. Inter-rater reliability as calculated by an Intraclass Correlation Coefficient, and either the Pearson or Spearman rho correlation and found to be reliable between clients and caregivers (rICC =.636, p <.001; rho =.642, p <.001). More specifically, current level of participation demonstrated acceptable reliability (rICC =.513, p <.001; r =.521, p <.001) as did wishing to improve participation (rICC =.689, p <.001; r =.725, p <.001). This supports the PHWA as a clinically relevant health and wellness occupational therapy assessment. [ABSTRACT FROM AUTHOR]
