Abstract

Abstract
Introduction: In a new culture, implementing treatment initially requires assessing and confirming the feasibility programs. Given the importance of feasibility in the expansion of psychotherapy programs, the present study aimed to develop and content validate the feasibility questionnaires from the perspectives of experts, therapist/clinician, patients (and in the case of children and adolescents, patients’ parents).
Method: The present study followed a descriptive-survey design. After searching the literature on the concept of feasibility and developing 4 versions of the feasibility questionnaire from the perspectives of experts, therapist/clinician, patients, and patients’ parents (in the case of children and adolescents), the content validity of the questionnaires was determined according to the opinions of 10 experts by calculating the content validity index (CVI) and content validity ratio (CVR) among psychologists who were at least doctoral students and had clinical experience of at least 5 years, selected based on a purposive sampling method.
Findings: By removing unacceptable items, the content validity of the final version of the general feasibility questionnaire for experts was confirmed with 29 items by removing 9 items, the session-by-session feasibility questionnaire with 18 items by removing 4 items, the parent feasibility questionnaire with 15 items by removing 2 items, and the patients (child) feasibility questionnaire with the same 12 items without removing any items.
Discussion and Conclusion: Despite the accessibility of similar feasibility tools, the present study attempted to present, for the first time, a coherent set of questionnaires for assessing the feasibility of therapeutic interventions, while paying attention to the greatest possible content comprehensiveness, focusing on the perspectives of different audiences such as experts, clinicians, patients, and in the case of children and adolescents, patients’ parents. In addition to adaptability to therapeutic programs, these questionnaires are able to assess the feasibility with respect to other programs.
