Abstract
Purpose/objective: This study sought to develop and evaluate the psychometric properties of a brief measure of the quality of therapist treatment delivery that would be applicable for use across different types of psychosocial chronic pain treatments: the Therapist Quality Scale (TQS).
Research method/design: An initial pool of 14 items was adapted from existing measures, with items selected that are relevant across interventions tested in a parent trial comparing an 8-week, group, Zoom-delivered mindfulness meditation, cognitive therapy, and behavioral activation for chronic back pain from which data for this study were obtained. A random selection of 25% of video-recorded sessions from each cohort was coded for therapist quality (two randomly selected sessions per group), with 66 sessions included in the final analyses (n = 33 completed pairs). Items were coded on a 7-point Likert-type scale. Exploratory factor analysis (EFA) and reliability estimates were generated.
Results: EFA showed a single-factor solution that provided a parsimonious explanation of the correlational structure for both sessions. Eight items with factor loadings of ≥ .60 in both sessions were selected to form the TQS. Reliability analyses demonstrated all items contributed to scale reliability, and internal consistency reliabilities were good (αs ≥ .86). Scores for the eight-item TQS from the two sessions were significantly correlated (r = .59, p < .001).
Conclusions/implications: The TQS provides a brief measure with preliminary psychometric support that is applicable for use across different types of treatments to rate the quality of the therapist's delivery. The items assess quality in delivering specific techniques, maintaining session structure, and in developing and maintaining therapeutic rapport.

期刊介绍:
Rehabilitation Psychology is a quarterly peer-reviewed journal that publishes articles in furtherance of the mission of Division 22 (Rehabilitation Psychology) of the American Psychological Association and to advance the science and practice of rehabilitation psychology. Rehabilitation psychologists consider the entire network of biological, psychological, social, environmental, and political factors that affect the functioning of persons with disabilities or chronic illness. Given the breadth of rehabilitation psychology, the journal"s scope is broadly defined.
