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
MBCT
Core mechanism: Mindful awareness of depressive cognitive patterns enables decentering and prevents ruminative relapse spirals
Ontology: Depressive relapse maintained by reactivation of ruminative cognitive patterns triggered by low mood

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.
MBCT
Philosophical roots: Buddhist psychology (mindfulness, non-attachment to thoughts); Husserl (epoché — suspending natural attitude); Kabat-Zinn (secularized dharma); Teasdale (interacting cognitive subsystems)
Blind spots: Primarily relapse prevention — not first-line for acute depression; requires meditation capacity some clients lack
Therapeutic voice: Notice the thought arriving — not as truth, but as a mental event. Thoughts are not facts.
Choosing between them
CBT-I and MBCT both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
