BACKGROUND: Cutaneous Leishmaniasis (CL) is an important public health issue in at least 83 countries, including Iran. Individuals' behavior modification is believed to be one of the best ways for CL prevention. However, no comprehensive questionnaires have been psychoanalyzed for identification of CL prevention behaviors and its numerous associated factors, as well as the impact of educational messages. Thus, the present study was conducted to develop and psychometrically assess CL prevention behaviors questionnaire in female students. METHODS: The present study was performed from October 2020 to May 2021 by developing a preliminary questionnaire based on integration of Cultural Model and Extended Parallel Process Model. The questionnaire was completed online by 460 adolescent female students living in endemic areas of Isfahan, Iran. Exploratory factor analysis was performed using SPSS 24 to ensure the construct validity. Internal reliability was assessed via Cronbach's alpha and external reliability was determined using the test-retest method based on the intraclass correlation coefficient (ICC) index. RESULTS: The first version of the questionnaire contains 110 items, out of which 82 remained according to content validity ratio (CVR) and content validity index (CVI) criteria. Afterwards, 11 items were removed due to low factor load in the construct validity process using the factor analysis technique. Ultimately, a 71-items questionnaire was developed and 12 factors were extracted from it. According to Cronbach's alpha index, the internal reliability for the questionnaire was 0.877 and the ICC index calculated the external reliability as 0.833. CONCLUSIONS: Integration of a Cultural Model with individual model was used for the first time to measure the factors related to CL prevention behaviors in this questionnaire; owing to the strength of the factor structure and appropriate psychometric properties, the questionnaire is applicable in the evaluation process of educational interventions concerning CL prevention, especially in female students.
背景：皮肤利什曼病（CL）是至少 83 个国家的一个重要公共卫生问题，包括伊朗。人们认为改变行为是预防 CL 的最佳方法之一。然而，目前还没有综合问卷来分析识别 CL 预防行为及其众多相关因素，以及教育信息的影响。因此，本研究旨在开发和心理评估女性学生 CL 预防行为问卷。
方法：本研究于 2020 年 10 月至 2021 年 5 月进行，通过整合文化模型和扩展平行过程模型，制定初步问卷。问卷由居住在伊朗伊斯法罕流行地区的 460 名青少年女性在线完成。采用 SPSS 24 进行探索性因素分析，以确保结构效度。采用克朗巴赫α系数评估内部信度，采用 ICC 指数基于测试-再测试法确定外部信度。
结果：问卷的第一版包含 110 个项目，根据内容效度比（CVR）和内容效度指数（CVI）标准，有 82 个项目保留。之后，根据构建效度过程中的因素分析技术，由于因素负荷低，有 11 个项目被删除。最终开发出一个包含 71 个项目的问卷，从中提取出 12 个因子。根据克朗巴赫α系数，问卷的内部信度为 0.877，ICC 指数计算的外部信度为 0.833。
结论：该问卷首次将文化模型与个体模型相结合，用于测量与 CL 预防行为相关的因素；由于结构强度和适当的心理测量特性，该问卷适用于 CL 预防教育干预的评估过程，特别是在女性学生中。
