Data_WP5_3 Sleep Quality Surveys

This dataset was used to collect quantifiable indicators of sleep quality. It targeted the general population, with particular focus on gathering sleep macro-architecture, common sleep disorders (such as insomnia, restless leg syndrome, micro-arousals, and wakefulness after sleep onset), and sleep-related breathing disorders (including hypopnea, apnea, and oxygen desaturation). The dataset includes responses provided by volunteers to internationally validated surveys, administered both before and after the intervention (Phase IIa and Phase IIb), employing the following standardized instruments: 1) Pittsburgh Sleep Quality Index (PSQI): A self-rated questionnaire that evaluates sleep quality and disturbances. It measures seven components: (a) subjective sleep quality, (b) sleep latency, (c) sleep duration, (d) habitual sleep efficiency, (e) sleep disturbances, (f) use of sleep medication, and (g) daytime dysfunction (Buysse et al., 1989). 2) Epworth Sleepiness Scale (ESS): A self-administered questionnaire consisting of 8 items that assess the likelihood of dozing off or falling asleep in different daily situations (Johns, 1991). 3) Berlin Questionnaire: A self-administered screening tool designed to identify individuals at high risk for obstructive sleep apnea (OSA), particularly in primary care settings. It includes questions related to (a) snoring, (b) daytime sleepiness or fatigue, (c) body mass index (BMI), and (d) hypertension (Netzer et al., 1999). Data are stored by ULL, and each data file is accompanied by a data dictionary to support the identification and interpretation of the variables, questions, and response options.
