Autism Spectrum Disorder (ASD) merupakan gangguan perkembangan yang memengaruhi kemampuan interaksi sosial dan komunikasi. Anak ASD sering mengalami gangguan tidur, dengan prevalensi sekitar 40–80%. Masalah tidur yang tidak ditangani dengan baik dapat memperburuk perilaku maladaptif seperti agresi, kecemasan, kesulitan beradaptasi sosial. Occupational Therapy Practice Framework (OTPF) menekankan bahwa kualitas tidur merupakan bagian penting dalam domain okupasi. Penelitian ini bertujuan menganalisis hubungan antara kualitas tidur dan perilaku maladaptif pada anak ASD. Desain penelitian menggunakan pendekatan cross-sectional dengan subjek anak yang didiagnosis ASD. Instrumen yang digunakan adalah Children’s Sleep Habits Questionnaire (CSHQ) menilai kualitas tidur dan Strengths and Difficulties Questionnaire (SDQ) menilai perilaku maladaptif. Uji normalitas data dilakukan dengan Shapiro-Wilk dan analisis hubungan menggunakan uji Spearman. Hasil penelitian menunjukkan adanya hubungan positif antara kualitas tidur dan perilaku maladaptif anak ASD (ρ = 0,265; p = 0,036). Meskipun hubungan yang ditemukan rendah, kualitas tidur tetap berperan penting terhadap munculnya perilaku maladaptif. Selain itu, analisis regresi menunjukkan usia (p = 0,010) dan jenis kelamin (p = 0,017) juga memiliki hubungan signifikan dengan perilaku tersebut.

Autism Spectrum Disorder (ASD) is a developmental disorder that affects social interaction and communication skills. ASD children often experience sleep disturbances, with a prevalence of around 40-80%. Untreated sleep problems can exacerbate maladaptive behaviors such as aggression, anxiety, social adaptation difficulties. The Occupational Therapy Practice Framework (OTPF) emphasizes that sleep quality is an important part of the occupational domain. This study aims to analyze the relationship between sleep quality and maladaptive behavior in ASD children. The research design used a cross-sectional approach with the subject of children diagnosed with ASD. The instruments used were Children's Sleep Habits Questionnaire (CSHQ) assessing sleep quality and Strengths and Difficulties Questionnaire (SDQ) assessing maladaptive behavior. Data normality test was conducted with Shapiro-Wilk and relationship analysis using Spearman test. The results showed a positive relationship between sleep quality and maladaptive behaviors of ASD children (ρ = 0.265; p = 0.036). Although the relationship found is low, sleep quality still plays an important role in the emergence of maladaptive behavior. In addition, regression analysis showed that age (p = 0.010) and gender (p = 0.017) also had significant associations with these behaviors.
