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

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.

Health Literacy, Awareness and Self-Efficacy among Cardiovascular Patients Visiting Medical Centers of Shahr-e Kord

@#Introduction: Considering the importance of self-efficacy and since inadequate health literacy can be a serious barrier to the participation and ultimately affect the health of patients. The present research aimed to study the health literacy of cardiovascular patients and its relationship with awareness and self-efficacy. Methods: This research was a descriptive and cross-sectional study which was conducted on 138 cardiovascular patients visiting medical centers of Shahr-e Kord in 2016. The participants were selected using simple random sampling. To assess the health literacy of the participants, TOFHLA was used. The self-efficacy standard questionnaire was applied to measure the self-efficacy of participants. The obtained data were statistically analyzed using descriptive and analytical tests in SPSS-18. Participation in the present study was voluntary. Results: The mean age of participants was equal to 48.59±19.05. Based on the results, 64, 13 and 61 patients had an inadequate, marginal, and adequate level of health literacy, respectively. The mean score of awareness was 68.14±21.68 and the mean score of self-efficacy was obtained 37.90±32.65. There is a direct and significant relationship between awareness, self-efficacy, and health literacy (p=0.000), and awareness is a suitable predictor of health literacy. Conclusion: it is necessary to measure the health literacy and the relevant skills in patients before providing information to them in medical centers. Then, commensurate with their level of information, training programs should be planned to empower patients and increase their self-efficacy, so that they can achieve correct health information.
