title: Psychometric Analysis of the Perceptions of Computerized Therapy Questionnaire-Patient Version (PCTQ-P).
abstract: Dissemination and implementation science (DIS) in psychology is a growing area of research, with the potential to increase access to evidence based care. However, the field is characterized by a paucity of validated measures of DIS constructs. The present study aimed to fill this gap in the literature by examining the psychometric properties of the Perceptions of Computerized Therapy Questionnaire-Patient Version (PCTQ-P), a self-report questionnaire for potential consumers based on Diffusion of Innovations theory. Undergraduate students participated in this two-study design, and were instructed to complete a battery of self-report measures, including the PCTQ-P. Internal consistency reliability, retest reliability, and discriminant validity were evaluated. Results provide evidence that the PCTQ-P is a psychometrically sound instrument for assessing potential consumers' perceptions of computer-based psychological treatments that are distinct from general help-seeking attitudes. With slight adaptation, the PCTQ-P can be used to examine other therapeutic modalities. Potential applications of the measure are discussed.
