Brief Summary
This study aims to adapt the Sleep Screening Scale for Children and Adolescents with Complex Chronic Conditions (SCAC) into Turkish and test its reliability and validity for this population. Children and adolescents with complex chronic conditions (CCC) often have ongoing and multiple health problems. These children often face a high risk of sleep problems, but there are no screening tools in Turkish designed specifically for them. The main goal is to confirm that the Turkish version of the SCAC is accurate and reliable. The study will also look at how common different types of sleep problems are in children with CCC, and how these problems are related to factors such as diagnosis, age, sex, and other medical conditions. Another goal is to compare children's sleep at home with their sleep during a stay in the pediatric intensive care unit (PICU). The study will also examine how environmental factors (such as light and noise) and medical factors (such as pain, medications, and devices) affect sleep in the hospital. After discharge, sleep recovery will be followed for up to 3 months using sleep diaries and actigraphy (a wearable device that measures movement during sleep).

Outcome Measures
Primary Outcomes (3)
Psychometric validation of the Turkish version of the Sleep Screening Scale for Children and Adolescents with Complex Chronic Conditions (SCAC)
Description: The primary outcome is the psychometric validation of the Sleep Screening Scale for Children and Adolescents with Complex Chronic Conditions (SCAC), originally developed by Larissa Alice Kubek and adapted into Turkish (Kronik Karmaşık Durumu Olan Çocuklar ve Ergenler İçin Uyku Tarama Anketi; KUBA) through forward-backward translation. The scale consists of 29 items grouped into four factors based on the International Classification of Sleep Disorders - Third Edition (ICSD-3) diagnostic categories: Sleep initiation and maintenance (7 items) Sleep-related breathing and arousals (9 items) Daytime sleepiness (7 items) Sleep-related movements (6 items) Each item is rated for the frequency of symptoms in the past 7 days, with higher scores indicating a greater presence of sleep-related problems. The total score ranges from 0 to 203, and subscale scores range from 0 to 63 depending on the number of items in each factor. Internal consistency will be assessed using Cronbach's
At enrollment (hospitalization)
Test-retest reliability of the Turkish version of the SCAC
Test-retest reliability will be assessed in a subgroup of participants by re-administering the SCAC at least four weeks after discharge from the pediatric intensive care unit (PICU). Reliability will be calculated using intraclass correlation coefficients (ICCs) for the total and subscale scores
At least 4 weeks post-discharge from PICU
Prevalence and subtype distribution of sleep disturbances in children with Complex Chronic Conditions (CCC)
Sleep disturbances will be assessed using the SCAC Scale. The questionnaire has 29 items; each item is rated for frequency of occurrence in the past 7 days (0 = never, 7 = every day). Four subscale scores are calculated based on the SCAC domains: (1) Sleep initiation and maintenance (7 items, score range 0-49), (2) Sleep-related breathing and arousals (9 items, score range 0-63), (3) Daytime sleepiness (7 items, score range 0-49), and (4) Sleep-related movements (6 items, score range 0-42). The total score ranges from 0 to 203, with higher scores indicating greater presence of sleep-related problems.
At enrollment (hospitalization)
Secondary Outcomes (6)
Objective sleep parameters during PICU stay
During PICU hospitalization (up to 30 days)
Correlation of environmental and clinical factors with sleep efficiency (actigraphy and sleep diaries)
From Day 1 of PICU admission through discharge (up to 30 days)
Comparison of home and hospital sleep patterns
Home baseline: parent-reported 7 days prior to admission; PICU: Day 7 of admission or at discharge if earlier
Change in SCAC Scores From Hospitalization to 3 Months Post-Discharge
Baseline (hospitalization),15 days, 1,2, 3 months post-discharge
Time to Return to Pre-Hospital Sleep-Wake Pattern
Baseline (hospitalization),15 days, 1,2, 3 months post-discharge
