Lack of accurate menstrual knowledge, attitude, and practices leave female adolescents ignorant of the necessary health behaviors during menstruation. This study aimed to develop a menstrual health-seeking behavior questionnaire based on the theory of planned behavior to evaluate its psychometric properties in female adolescents in Tehran.
This study was conducted on 578 female adolescents aged 12-15 years in Tehran. The first draft of the menstrual health-seeking behavior questionnaire containing 52 items was developed based on the theory of planned behavior (TPB). The content and face validity of the questionnaire was assessed by a panel of experts. Construct validity was also assessed using exploratory factor analysis (KMO=0.73) with varimax rotation. Cranach's alpha and test-retest were used to examine the reliability of the questionnaire. All statistical analysis was performed using SPSS 23.0 and AMOS 23.0.
The content and face validity of the 42 items were finally confirmed. Content validity index was greater than 0.73 for all six TPB constructs. Explanatory factor analysis yielded an acceptable fit for the six-factor model (RMSE=0.053, 95% CI 0.042-0.064). These factors jointly explained 65% of the variance in the outcome variables. Cranach's alpha coefficients ranged from 0.79 to 0.91, demonstrating an excellent internal consistency and high reliability of the questionnaire. Test-retest reliability was also satisfactory for all items (ICC=0.86-0.94).
The results illustrate that the menstrual health-seeking behavior questionnaire is psychometrically adequate and highly reliable. This theoretically grounded questionnaire can be well applied in future interventions for female adolescents to assess their menstrual health-related knowledge, attitude, and practices.
缺乏准确的月经知识、态度和行为，使女性青少年对月经期间必要的健康行为一无所知。本研究旨在基于计划行为理论开发一份月经健康寻求行为问卷，以评估其在德黑兰女性青少年中的心理测量特性。
本研究对德黑兰578名12至15岁的女性青少年进行。基于计划行为理论（TPB）编制了包含52个条目的月经健康寻求行为问卷初稿。由专家小组评估问卷的内容效度和表面效度。还使用探索性因素分析（KMO = 0.73）和方差最大化旋转来评估结构效度。使用Cronbach's alpha和重测法来检验问卷的信度。所有统计分析均使用SPSS 23.0和AMOS 23.0进行。
最终确认了42个条目的内容效度和表面效度。所有六个TPB结构的内容效度指数均大于0.73。解释性因素分析得出六因素模型的拟合度可接受（RMSE = 0.053，95% CI 0.042 - 0.064）。这些因素共同解释了结果变量中65%的方差。Cronbach's alpha系数范围为0.79至0.91，表明问卷具有出色的内部一致性和高信度。所有条目的重测信度也令人满意（ICC = 0.86 - 0.94）。
结果表明，月经健康寻求行为问卷在心理测量方面是充分的且高度可靠。这份基于理论的问卷可很好地应用于未来针对女性青少年的干预措施中，以评估她们与月经健康相关的知识、态度和行为。
