Data were collected using the "Patient Information Form" including sociodemographic and disease related characteristics, the Electrophysiological Severity Classification, Pittsburgh Sleep Quality Index (PSQI), Brief Pain Inventory (BPI), and SF-12 Health Survey.

Background: Sleep disturbances are common in diabetic polyneuropathy (DPN) and adversely affect physical and psychological well-being. This study aimed to evaluate the effects of sleep hygiene education on sleep quality, pain severity, and quality of life in patients with painful DPN. Methods: This randomized controlled trial was conducted between January 2025 and January 2026 and enrolled 24 patients with electrophysiologically confirmed painful DPN, randomized equally into intervention (n = 12) and control (n = 12) groups. The intervention group received a standardized sleep hygiene education protocol over three months; the control group continued routine care. Participant blinding was not feasible given the nature of the intervention; statistical analyses were conducted with group codes masked. Outcomes were assessed at baseline (T0), month 1 (T1), and month 3 (T2) using the Pittsburgh Sleep Quality Index (PSQI), Brief Pain Inventory (BPI), and SF-12 Health Survey. Financial Support: The present study was supported by the Research Fund of Trakya University. Project No: 2025/19
