Methods: In Study 1, 349 Turkish-speaking adults (57% female; M = 24.05 years, range = 18-68) completed the translated Vamping Scale with related sleep and procrastination measures. CFA, item-total correlations, and IRT assessed factor structure and item properties, while reliability was evaluated with α, ω, and λ6. In Study 2, 342 adults (56% female; M = 26.65 years, range = 18-56) completed the Vamping Scale with mental health and well-being measures. Pearson correlations and SEM tested whether psychological distress mediated the relationship between vamping and well-being.
Results: A revised 10-item, two-factor model showed acceptable fit (CFI = .901; SRMR = .0562) and high internal consistency (α = .890). Vamping was positively related to bedtime procrastination, sleep effort, and psychological distress, and negatively to life satisfaction and well-being. SEM confirmed psychological distress mediated the link between vamping and well-being.
Conclusion: The Turkish Vamping Scale is a psychometrically sound instrument for assessing late-night technology use behaviors in adult populations. The findings underscore the detrimental associations between vamping, sleep-related difficulties, and psychological distress, supporting the need for targeted interventions. Future research should incorporate longitudinal designs and objective sleep measures to clarify causal pathways.
