Scale Development and Psychometric Evaluation of the Preoperative Assessment of Readiness Tool

Abstract

Technology has greatly advanced surgical capacity; however, the patient's perspective of surgical readiness remains unexplored. There is also a paucity of psychometrically sound instruments quantifying surgical readiness. Hence, this study developed and psychometrically evaluated the Preoperative Assessment of Readiness Tool (PART). A methodological study. An initial 25-item questionnaire was developed after preliminary interviews and literature review. Psychometrics included content and construct validity and internal consistency. PART was tested on 210 purposively selected preoperative patients and preliminary factor analyses examined two random halves of the sample. The questionnaire was reduced to 21 items after content validation and was further reduced to 15 items after preliminary factor analyses. Final factor analysis extracted two factors: quality information acquisition and supportive interpersonal care assimilation. Scale reliability was 0.97 with acceptable subscale reliability. The 15-item Preoperative Assessment of Readiness Tool demonstrated satisfactory psychometrics in assessing perceived surgical readiness. Nonetheless, further analysis is warranted to guarantee robust cross-cultural and cross-geographical comparisons.
