The development of a client self-report instrument to measure satisfaction with family therapy treatment
Abstract
This project involved the evaluation of the psychometric properties of the Purdue Family Therapy Satisfaction Scale (PFTSS). The PFTSS was developed by the faculty of the Marriage and Family Therapy Program, Purdue University. Items to measure the construct, client satisfaction, were formulated from current theory and outcome research in marriage and family therapy. Judges evaluated the items resulting in 43 being retained for the preliminary version of the PFTSS. This preliminary version of the PFTSS was administered to 470 clients receiving therapy at two university based marriage and family therapy treatment centers. Construct validity was assessed through exploratory and confirmatory factor analysis. The sample was randomly divided in two with one half of the sample being selected for exploratory FA. Results of the exploratory FA indicated the best solution consisted of 1 factor. This differed from the theorized solution which had presented satisfaction with family therapy services as a construct having four dimensions. Reliability estimation was made using the internal consistency model. Cronbach's alpha for the data in sample A was.91. The second half of the sample was retained for confirmatory factor analysis. It was hypothesized that data from the second sample would confirm the single factor solution generated by the exploratory FA. This hypothesis was confirmed employing Chi-square goodness-of-fit of the factor model statistics. Additional statistical tests supported the hypothesis. Pearson's product-moment coefficient for comparing both pattern and magnitude of item loadings between two data sets was.87. The Coefficient of Congruence developed to compare the factor pattern matrices of data sets was.99. Cronbach's alpha for data set B was.92. Results of this study provide evidence for the reliability and validity of the PFTSS. Directions for continued scale development are presented.
