Design and psychometric properties of a questionnaire for assessing sexual and reproductive health needs of married adolescent women: an exploratory sequential mixed methods study.

To date, there is no valid and reliable instrument to specifically evaluate married adolescent women's sexual and reproductive health (SRH) needs. Hence, the aim of this study was to develop and evaluate the psychometric properties of a questionnaire for assessing married adolescent women (MAW)'s SRH needs. The current exploratory sequential mixed method study was performed in two phases. In the first phase, a preliminary questionnaire was developed based on in-depth interviews with 34 MAW and four key informants as well as a comprehensive literature review. In the second phase, validity of the questionnaire was assessed using face, content, and construct validity and reliability of the questionnaire was assessed using internal consistency and test-retest reliability. Based on qualitative content analysis and literature review, 137 items were extracted. After several modifications of the generated items, a 108-item questionnaire was prepared for the psychometric process. After checking face and content validity, 85 items remained in the study. In the exploratory factor analysis, 11 items were removed and the remaining 74 items were categorised into nine factors. Cronbach's alpha coefficient and the intraclass correlation coefficient were found to be 0.878 and 0.99 for the whole scale, respectively.Impact Statement Sexual and reproductive health (SRH) needs of married adolescent women (MAW) are different from those of married adult women or unmarried, sexually active adolescents. However, there are to date no valid and reliable instruments to specifically evaluate the SRH needs of this group of women. The final version of questionnaire consists of 74 items in nine domains including need to improve MAW's sexual quality of life, promote MAW's SRH self-care, improve MAW's SRH self-efficacy, increase MAW's SRH knowledge, increase husband's involvement in MAW's SRH, improve the performance of health care providers, strengthen the family support to married adolescent women, improve family involvement in SRH education of MAW, and provide specific premarital counselling to MAW. The 74-item questionnaire has acceptable validity and reliability. Therefore, it can be used by researchers and policymakers as an appropriate instrument for assessing MAW's SRH needs.
