Development and psychometric evaluation of waste separation beliefs and behaviors scale among female students of medical sciences university based on the extended parallel process model.

ABSTRACT: BACKGROUND:The increasing production of un-recycled waste is a great threat to public health. Therefore, assessment and measurement of people's beliefs and perceptions with regard to these threats can contribute to the development of suitable educational messages promoting waste separation behaviors. This study aimed to carry out the scale development and psychometric evaluation of behaviors and beliefs associated with waste separation among female students. METHOD:This methodological research was performed in 2019. The primary questionnaire was developed based on the assessment of waste separation beliefs and behaviors based on the extended parallel process model. Afterwards, to confirm the content and face validity of the research tool, the opinions of 14 faculty members and certain students were asked for, respectively. In order to assess the construct validity of the questionnaire, exploratory factor analysis was performed based on the data collected from 386 female students in Isfahan University of Medical Sciences, Iran. The internal and external reliability of the tool was determined through estimating Cronbach's alpha and test-retest based on intraclass correlation (ICC) index, respectively. RESULTS:The mean age and academic semester of the students were 22 ± 1.9?years and 5.58 ± 2.6, respectively. The primary version of the questionnaire was designed with 65 items; one item was omitted during the content validity process. Construct validity with factor analysis technique yielded nine dimensions including 64 items with a factor loading above 0.3. The overall reliability of the research tool was confirmed at Cronbach's alpha of 0.87. Furthermore, the ICC of the entire questionnaire was 0.89. CONCLUSION:According to the results of the study, the final 64-item questionnaire could be used by various researchers to assess waste separation beliefs and behaviors considering suitable psychometric features.

Project description:BackgroundCutaneous 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.MethodsThe 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.ResultsThe 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.ConclusionsIntegration 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.
