How they work
CBT-I
Core mechanism: Sleep restriction and stimulus control consolidate sleep drive and decondition wakefulness; cognitive restructuring reduces hyperarousal and catastrophic thinking about sleep
Ontology: Chronic insomnia as a learned disorder of hyperarousal and conditioned sleeplessness maintained by maladaptive behaviors and beliefs, not a primary neurological deficit
MBSR
Core mechanism: Systematic mindfulness practice cultivates non-reactive awareness that reduces stress reactivity and ruminative cycles
Ontology: Suffering amplified by reactivity to experience; mindfulness interrupts habitual stress response patterns

What each assumes — and misses
CBT-I
Philosophical roots: Behavioral learning theory (Pavlov, Skinner); cognitive appraisal theory; Spielman's 3P model (predisposing, precipitating, perpetuating factors)
Blind spots: Sleep restriction can be challenging for people with bipolar disorder (may trigger mania); requires motivation and tolerance of short-term worsening; group or digital formats may not address comorbidities
Therapeutic voice: We're going to compress the time you spend in bed to build up your sleep drive. It will feel harder before it feels easier.
MBSR
Philosophical roots: Buddhist Vipassana and Zen traditions; Kabat-Zinn (secularized mindfulness); Husserl (phenomenological reduction); James (stream of consciousness); Thich Nhat Hanh
Blind spots: Mindfulness practice can be contraindicated for some trauma survivors; structured program may not suit all learning styles
Therapeutic voice: Bring your attention to the breath. When the mind wanders — and it will — gently bring it back without judgment.
Choosing between them
CBT-I (Cognitive-Behavioral) and MBSR (Integrative) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
