From the Guidelines
Cognitive Behavioral Therapy (CBT) for Delayed Sleep Phase Disorder (DSPD) should be administered using a multicomponent approach, combining cognitive therapy strategies with education about sleep regulation, stimulus control instructions, and sleep restriction therapy, as outlined in the American Academy of Sleep Medicine systematic review and meta-analysis 1. To administer CBT for DSPD, begin with a comprehensive sleep assessment, then implement a structured program that includes sleep education, cognitive restructuring, and behavioral interventions. The therapy typically involves 6-8 weekly sessions of 45-60 minutes each. Key components include:
- Challenging negative thoughts about sleep timing (such as "I can never wake up early" or "I'll feel terrible if I change my schedule") using cognitive therapy strategies 1
- Implementing gradual sleep schedule adjustments (usually advancing bedtime by 15-30 minutes every few days) using stimulus control instructions 1
- Establishing consistent sleep hygiene practices, such as avoiding caffeine and electronics before bedtime, and creating a relaxing sleep environment 1
- Using light therapy strategically (bright light in the morning, avoiding blue light at night) to help regulate the body's circadian rhythms 1
- Sleep restriction may temporarily limit time in bed to increase sleep efficiency, as outlined in the sleep restriction therapy approach 1 Throughout treatment, patients should maintain a sleep diary to track progress and identify patterns. CBT for DSPD works by addressing both the physiological aspects of delayed circadian rhythm and the psychological barriers to changing sleep patterns, making it an effective non-pharmacological approach for long-term management of this sleep disorder. Some of the key single-component treatments that can be used in conjunction with multicomponent CBT-I include:
- Stimulus control: a set of instructions designed to extinguish the association between the bed/bedroom and wakefulness and establish a consistent wake-time 1
- Sleep restriction therapy: a method designed to enhance sleep drive and consolidate sleep by limiting time in bed equal to the patient’s sleep duration 1
- Cognitive therapy: a set of strategies including structured psychoeducation, Socratic questioning, use of thought records, and behavioral experiments designed to identify and modify unhelpful beliefs about sleep 1
- Relaxation therapy: structured exercises designed to reduce somatic tension and cognitive arousal that may perpetuate sleep problems 1
- Sleep hygiene: a set of general recommendations about lifestyle and environmental factors that may promote or interfere with sleep 1
From the Research
Species of Cognitive Behavioral Therapy (CBT) for Delayed Sleep Phase Disorder (DSPD)
- CBT plus bright light therapy (BLT) is a species of CBT that has been shown to be effective in treating DSPD in adolescents 2
- This approach combines morning bright light therapy to advance the circadian rhythm with cognitive restructuring and sleep education to target associated insomnia and sleep hygiene
Administration Methods for CBT in DSPD
- CBT can be administered in individual sessions, with a typical duration of 6 sessions 2
- Morning bright light therapy can be used in conjunction with CBT to advance the circadian rhythm 2
- Evening melatonin administration can also be used as a sole treatment or in combination with CBT 3, 4
Addressing Unhelpful Beliefs about Sleep Timing
- Cognitive restructuring is a key component of CBT for DSPD, and can help individuals identify and challenge unhelpful beliefs about sleep timing 2
- Sleep education can also help individuals understand the importance of a consistent sleep schedule and the consequences of delayed sleep phase 2
Consequences of Sleep Schedule Changes
- Delayed sleep phase can have significant consequences, including impaired school/work performance, mental health problems, and increased risk of sleep-onset insomnia 5, 4
- Treatment of DSPD can help individuals establish a more consistent sleep schedule, which can have positive effects on overall health and well-being 2
