Intervention research has been identified as a top nursing research priority in the United States for the 21st century (Hinshaw, 2000). A key challenge in this research is to develop methods to empirically verify the reliable delivery of experimental interventions. The purpose of this study is to describe the development and validation of a measure of psychosocial treatment adherence. Methodology: The Technology Model approach (Waskow, 1984) was used to identify and quantify a list of the key nurse therapist activities. This approach includes the following steps: a.) Literature review; b.) Identification of unique and common activities of the treatment and control interventions; c.) Construction of scale items written in terms of objective therapist behaviors; d.) Item scaling; e.) Definition of the behavioral unit for coding; f.) Pilot testing; g.) Item revision; and h.) Psychometric testing. Results: The Possibilities Project Psychotherapy Coding Questionnaire (PPPCQ), a 60-item instrument comprised of three 20-item subscales, was developed to assess therapist adherence in the study of a new psychotherapy for the treatment of women with eating disorders. A total of 140 psychotherapy sessions from the pilot study were rated by two independent coders and data analyses is in process. Item discriminability and construct validity will be examined using known group comparisons, and profile analysis. Divergent validity will be evaluated by correlating the PPPCQ scores with a measure of therapeutic alliance (CALPAS). Pearson correlations will be used to examine relationships between subscales. Cronbach’s alpha will be computed for each subscale. Interrater reliability will be assessed. Implications: Results provide evidence that it is feasible to develop a coding approach to provide quantitative evidence of intervention adherence. Standardization of psychosocial interventions will help to ensure the validity of these studies, improve consistency, and enhance comparability across research findings.
