Modifying Cognitive-Behavioral Therapy for Fear of Sleeping Alone in a Child With Autism Spectrum Disorder

This case study demonstrates the use of a modified evidence-based treatment protocol for "Maya," a 13-year-old girl who presented with a fear of sleeping alone, Autism Spectrum Disorder (ASD), and separation anxiety disorder (SAD). The treatment, which spanned across 36 sessions, consisted of skills acquisition and exposure, with modifications made to address Maya's ASD symptoms and cognitive limitations. Modifications for treating comorbid anxiety and ASD are described, including the use of: forced-choice list for emotions and somatic cues of anxiety, concrete props for teaching skills, and a higher level of parent involvement than typical for adolescent clients being treated for anxiety. Based on in-office observations and parental reports of at-home behavior, Maya's avoidance of sleeping alone decreased over time, and she was able to sleep alone by the end of treatment. This case demonstrates successful treatment of fear of sleeping alone in a child with co-occurring anxiety and ASD.
