Abstract

Background: Millions of pedestrians are seriously injured, disabled, or lose their lives in road traffic accidents annually. The availability of a standard scale specifically for predicting road-crossing behaviors would be beneficial in research applications and in tailoring interventions. Objectives: The purpose of the current research was to psychometrically evaluate the safe road-crossing behaviors scale based on the Prototype Willingness Model (PWM) among college students. Methods: In this cross-sectional study, a purposive and multi-stage sampling method was used to select 315 students from Kermanshah University of Medical Sciences (KUMS) during 2018. The studied social-cognitive determinants from the PWM included attitude, subjective norms, prototype, intention, and willingness. Participants completed a written self-report questionnaire. Data was analyzed using SPSS (ver. 20.0). Exploratory factor analysis (EFA) with VARIMAX rotation was applied to determine the number and composition of constructs. Results: Five factors were extracted. The calculated Kaiser–Meyer–Olkin (KMO) value was 0.806. Overall, the PWM constructs explained 64.39% of the variance in the hypothesized model. Cronbach’s alpha for the measured constructs of attitude, subjective norms, prototype, intention, and willingness were 0.87, 0.81, 0.68, 0.71, and 0.61, respectively. Conclusion: The present study provides some support from among students at an Iranian university for the internal validity and reliability of the safe road-crossing behaviors scale. This scale could be used in planning interventions for the promotion of safe road-crossing behaviors among pedestrians.
伊朗大学生安全过马路行为量表的心理测量评价
背景:每年有数百万行人在道路交通事故中严重受伤、致残或丧生。提供一个专门用于预测过马路行为的标准量表,将有利于研究应用和定制干预措施。目的:利用原型意愿模型(PWM)对大学生安全过马路行为量表进行心理测量学评价。方法:采用横断面研究方法,采用有目的的多阶段抽样方法,对2018年克尔曼沙阿医科大学315名学生进行抽样调查。研究的社会认知决定因素包括态度、主观规范、原型、意图和意愿。参与者完成了一份书面自我报告问卷。数据采用SPSS (ver.)进行分析。20.0)。应用VARIMAX旋转探索性因子分析(EFA)确定构建体的数量和组成。结果:提取出5个因素。计算的KMO值为0.806。总体而言,PWM结构解释了假设模型中64.39%的方差。被测态度、主观规范、原型、意图和意愿构式的Cronbach’s alpha分别为0.87、0.81、0.68、0.71和0.61。结论:本研究对伊朗某高校学生安全过马路行为量表的内部效度和信度提供了一定的支持。该量表可用于规划促进行人安全过马路行为的干预措施。
