Abstract

Women with an abnormal Pap smear results are susceptible to distress. The objective of this study was to measure the reliability and validity of the Malay version of Psychosocial Effects with an Abnormal Pap Smear Questionnaire 14 Items (PEAPS-Q-14). A cross sectional study was conducted among 70 women with abnormal Pap smear results who were referred to three tertiary hospitals in East Coast Malaysia and completed colposcopy investigation. The self-administered PEAPS-Q-14 comprises of four domains and a total of 14 items. Descriptive analyses, Chronbach’s alpha and exploratory factor analysis were performed to measure the reliability and validity of the Malay version of PEAPS-Q-14. The final model of exploratory factor analysis on the Malay version of PEAPS-Q-14 indicated Bartlett’s Test of Sphericity was significant (Chi-square = 404.640, p value < 0.001) and the Kaiser-Meyer-Olkin (KMO) was 0.561. The items were reduced to four factors based on Eigenvalue exceeding 1 after removing an item. The retained 13 items fit the original PEAPS-Q14 subdomains well. The model with full items demonstrated acceptable overall internal consistency of 0.724 respectively. The Chronbach’s alpha of each domain in PEAPS-Q-14 range from 0.666 to 0.917 and only an item (Item 7) under the second factor revealed corrected total item correlation of 0.183. Removal of Item 7 has resulted in better reliability of Factor 2 in which its Chronbach’s alpha increased to 0.752. Therefore, the problematic item (Item 7) will be revised and replaced before further confirmatory factor analysis. This study showed the Malay version for PEAPS-Q-14 were reliable and valid to assess the psychosocial burden among women with abnormal Pap smear results based on exploratory factor analysis.
