N2  - Sleep disruption can occur following brain injury, however, insomnia prevalence and severity in adolescents with persistent postconcussion symptoms have not been investigated. This study examined: (1) some of the psychometric properties of the Insomnia Severity Index (ISI), (2) the prevalence and severity of insomnia symptoms, and (3) associations between insomnia symptoms and clinical measures of postconcussion symptoms, mental health symptoms, and cognitive tests in adolescents with slow recovery from concussion. Participants (N=121) were adolescents 13-18 years old (mean=16.2, SD=1.2) and on average of 6.4 months (SD=3.8) post-concussion. This sample rated insomnia (ISI), postconcussion symptoms, symptoms of depression and anxiety, and cognitive complaints, as well as completed cognitive testing. The ISI demonstrated good internal consistency (alpha=.87) and a single factor structure. The majority of the sample endorsed at least some insomnia, with 62% being over the clinical cut-off for experiencing clinically significant symptoms of insomnia. Higher insomnia severity was associated with a greater number of previous concussions, worse postconcussion symptoms, more anxiety, and higher depression. Insomnia was significantly associated with more cognitive complaints and higher rates of failure on performance validity tests, but not with actual objectively-measured cognitive abilities. Insomnia is common in adolescents with slow recovery from concussion and is associated with worse postconcussion symptoms, anxiety, depression, cognitive complaints, and performance validity concerns. Investigating evidence-based treatments for insomnia should be a priority in this population.<p />  <p>Language: en</p>
