CBT-I Versus CBT-I+ACT for Youths With Insomnia and Anxiety

Insomnia in adolescents and youth is a long-standing public health concern due to its high prevalence and association with various physical and mental health problems. Insomnia and psychiatric disorders are highly comorbid and intercorrelated in adolescents. Among all mental disorders, anxiety has been shown to be have high comorbidity with insomnia, affecting approximately 30% of individuals. CBT for insomnia (CBT-I) has been shown to be effective in improving sleep complaints and short-term improvement in mood while previous systematic reviews of interventional studies have demonstrated the effectiveness of acceptance and commitment therapy (ACT) interventions in treating insomnia, both as a primary condition and with other physical and/or mental health comorbidities. This study aims to compare the effect of CBT-I and CBT-I combined ACT in improving anxiety symptoms in youth.
