Abstract

Insomnia is a frequent complaint and is associated with impairments in physical and psychological health. Although Cognitive-Behavioral Therapy (CBT) demonstrates effective results for insomnia, there are those who do not respond to this type of intervention. In addition, many individuals present difficulties in implementing sleep restriction strategies and stimulus control. A new therapeutic modality, Acceptance and Commitment Therapy (ACT) can improve the treatment of insomnia, since integrating traditional strategies can increase adherence to behavioral treatment. The aim of this study is to evaluate the effectiveness of ACT for chronic insomnia in adults. Participants will be 100 adults aged between 18 and 59 years, diagnosed with chronic insomnia who will be randomly assigned to the ACT and CBT groups. For both groups, the intervention will be performed in six group and weekly sessions. The evaluation will occur in three moments: pre-treatment, post-treatment and six-month follow-up, through the instruments: Sleep Diary, Insomnia Severity Index, Epworth Sleepiness Scale, Hospital Anxiety and Depression Scale, Acceptance and Action Questionnaire-II, Dysfunctional Beliefs and Attitudes about Sleep. Evaluations of sleep patterns, daytime sleepiness, depression, anxiety, and avoidance of experience will be compared using mixed ANOVA, followed by multiple comparison tests, where appropriate. For the primary and secondary outcomes, the magnitude of the effect will be calculated. The size of the effect will be calculated using the square partial eta and d of Cohen. (AU)
