Vamping refers to the intentional delay of sleep to engage in late-night activities, often involving technology use, which may impair sleep and well-being. This study adapted the Vamping Scale into Turkish and examined its psychometric properties and relationships with sleep effort, bedtime procrastination, psychological distress, and well-being. 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.
