Abstract:

Objective To evaluate the validity and reliability of the IMB based questionnaire for reproductive health among unmarried rural-urban female migrants, and assess the application of the questionnaire in the target population in Shanghai. Methods Convenience sampling was adopted, and 944 unmarried rural-urban female migrants were selected from the examination centers for migrant workers in three districts of Shanghai to fill out the questionnaire for reproductive health. The questionnaire included basic personal information, knowledge, attitude, behaviors and demands of participants on reproductive health. The content validity was evaluated by experts discussion, the constructive validity was assessed by factor analysis, and the internal reliability was determined by calculating reliability coefficients. The test-retest reliability was measured with the same questionnaire among 40 participants at the interval of 2 weeks. Results All Cronbach´s alpha coefficients ranged between 0.313 and 0.824. Information of reproductive health and attitude towards regular sex partner were two internal reliability scales of the highest scores. The spearman correlation coefficients were larger than 0.5, which showed fine test-retest reliability （P<0.05）. Four factors explained 78.66% of the questionnaire by using factor analysis, and all factors could be regarded as information, motives, behavior techniques, and preventive action about reproductive health. Conclusion Overall the designed IMB based questionnaire can be applied to assess reproductive health among unmarried rural-urban female migrants with good reliability and validity, but relative scales of self-efficacy should be revised to accommodate the research about reproductive health of the population.
