Acceptance and Commitment Therapy as a New Treatment for Adults With Insomnia Disorder

Acceptance and Commitment Therapy (ACT) is a newer form of behavioral therapy working with acceptance, and the clarification of personal values. Acceptance, in this case, means the willingness to (temporarily) experience unpleasant sensations such as sleeplessness or tiredness without attempting to control or change them. Aims are, first, to reduce suffering due to unsuccessful control attempts (such as frustration, anger, anxiety) and second, to improve processes that are typically worsened by increased control efforts (such as sleep). Clarification of values means identifying aspects of life that are perceived as rewarding and encouraging approach-behavior in valued aspects of life (instead of avoidance-behavior that is often associated with insomnia and mental disorders).

CBT-I, the gold standard treatment for insomnia, consists of sleep education, relaxation, sleep restriction, and cognitive therapy.
