Objectives: The pregnancy-related anxiety questionnaire is one of the specialized scales designed for pregnancy-related anxiety measurement including fear of delivery, fear of birth of a handicapped child, and concern about pregnancy- and delivery-related body changes. The present study aimed to assess psychometric properties of Pregnancy Related Anxiety Questionnaire- Revised2 (PRAQ-R2) among Iranian women.
Materials and Methods: In this methodological, cross-sectional study, 109 pregnant women in the second trimester of pregnancy were studied through proportional randomized sampling. Content validity was evaluated in two qualitative (by experts) and quantitative (content validity ratio [CVR] and content validity index [CVI]) stages. In the next step, a confirmatory factor analysis was used to determine the validity of the structure. For reliability, the internal consistency (Cronbach α) was calculated and the stability of the questionnaire was analyzed using intragroup correlation coefficient with 20 samples.
b> Based on the results, the evaluation of content validity in quantitative step showed that CVI and CVR were 0.97 and 0.98 for PRAQ-R2, respectively. The reliability of the questionnaire calculated by intraclass correlation coefficient (ICC = 0.73) and internal correlation (α = 0.74) verified the high reliability of the instrument. Moreover, the construct validity was confirmed by confirmatory factor analysis.
Conclusions: In general, the findings support the validity and reliability of the questionnaire. Therefore, it is recommended that a short form of anxiety questionnaire be used to assess the anxiety and concerns of Iranian women during pregnancy in clinical trials.
