VALIDATION OF THE CROATIAN VERSION OF THE SURGICAL FEAR QUESTIONNAIRE (SFQ) IN ADULT PATIENTS WAITING FOR ELECTIVE...

The Surgical Fear Questionnaire (SFQ) is an instrument for self-assessment of surgical fear and consists of two subscales, one assessing the fear of short-term consequences (SFQ-s) and another one of long-term consequences (SFQ-l) of surgery. The aim of this study was to test the Croatian version of the SFQ with regard to its psychometric properties. This prospective cohort study included patients who presented to the Department of Surgery for elective surgery in the inpatient setting at a tertiary health care facility in Croatia between April 1 and May 31, 2019. Data on 144 patients were suitable for data analysis. Data collection was performed in the afternoon before surgery using the Personal Information Form, Numerical Rating Scale self-report instruments (NRS), SFQ and Hospital Anxiety and Depression Scale (HADS) assessing sociodemographic factors, surgical fear via NRS and SFQ, expected pain and emotional state. The Cronbach alpha value as a statistical measure for reliability of psychometric tests for the SFQ-s subscale was 0.79, for SFQ-L subscale 0.84, and for total SFQ 0.81. The exploratory factor analysis (EFA) showed a two-factor structure. Significant correlations of the SFQ with the NRS and HADS-anxiety subscale were demonstrated. Our study demonstrated the Croatian version of the SFQ to have a high level of reliability and hence can be used as a self-report instrument for surgical fear with two subscales. Convergent validity of the SFQ with other self-report instruments is shown.
