Abstract

Introduction: The rapid global rise in electronic cigarette (e-cigarette) use has led to increasing research interest, yet factors influencing its adoption remain underexplored in Malaysia. This study investigates sociodemographic and psychosocial determinants of e-cigarette use in the Samarahan and Kuching divisions of Sarawak, Malaysia. Methods: A cross-sectional study was conducted among smokers aged 18 and above. A total of 474 participants were recruited using cluster sampling. Data collection was performed through face-to-face interviews using a structured questionnaire. Hierarchical multinomial logistic regression was applied to identify key predictors of e-cigarette use. Results: Among participants, 27.8% were e-smokers, 25.8% were switchers, and 46.4% were dual smokers. The analysis revealed that females were more likely to be e-smokers (AOR = 5.889, p < .001) and switchers (AOR = 2.647, p = .021) than males. Additionally, degree holders were more likely to be e-smokers than dual smokers (AOR = 4.106, p = .025). Psychosocial factors, such as subjective norms (AOR = 1.435, p = .023) and perceived usefulness (AOR = 1.616, p = .016), were significant predictors of e-cigarette use. Conclusion: Sociodemographic and psychosocial factors, such as gender and education, influence e-cigarette use in Sarawak. These findings provide valuable insights for designing targeted public health strategies to regulate e-cigarette use and support smoking cessation efforts in Malaysia.

Abstract

Introduction: Menopause is generally considered a stressful experience, with 25% of menopausal women reporting that they experience stress. Using appropriate coping strategies can help reduce stress levels and alleviate other problems in menopausal women. Aims: This study aims to analyze the psychometric properties of two questionnaires designed to measure menopausal stress and coping strategies among menopausal women in Sarawak. Methods: The content validity of this study was assessed by calculating the I-CVI, S-CVI average, S-CVI universal agreement, and CVR. The face validity was also assessed for comparisons within subgroups. A cross-sectional study was conducted in Subis District, Sarawak, involving  221 menopausal women. Participants were selected using a purposive sampling technique and data were collected from face-to-face interviews. Psychometric analysis was performed using SPSS version 28.0. Results: A total of 38 questionnaire items were analyzed by experts for relevance, clarity, simplicity, and ambiguity. After the second modification, the I-CVI, S-CVI/Ave, and CVR for all domains and items were acceptable. Therefore, all items were retained. Face validity was also confimed with an average ICC of 0.979 and a 95% confidence interval between 0.96 and 0.99 (F (9,261a) = 47.996, p < 0.05). Meanwhile, reliability test with a Cronbach's alpha coefficient of greater than 0.70 indicated a good internal consistency. Conclusion: The questionnaires appeared to be a psychometrically sound instrument for measuring menopausal stress and coping strategies in menopausal women.
