Research gap at a glance
- Question: In people recovered from depression, does an intervention that targets bodily and sensory representation directly reduce somatosensory deactivation under dysphoria, a marker that cognitive prophylactic therapies leave unchanged, and does that reduction lower relapse?
- Why it matters: If the enduring vulnerability is the sensory factor and no current prophylactic therapy moves it, existing treatments work only on the modifiable half of relapse risk. A body-focused treatment that moved it would justify the wiki’s applied body-awareness approaches on clinical rather than theoretical grounds.
- Theme: Intervention
- Status: open
What the wiki already knows
- In a randomised fMRI trial of remitted depression, somatosensory deactivation under sad-film induction predicted relapse and did not change with either mindfulness-based or well-being cognitive therapy; combined with a prefrontal marker it gave C = 0.86 (Farb et al. (2022), Two-factor model of relapse vulnerability).
- In the same cohort during self-referential processing, the static somatosensory marker replicated, a somatosensory marker rose over treatment in people who stayed well, and only somatosensory markers survived in the combined model (Wu et al. (2026)).
- The model’s authors speculate the sensory factor might yield to skills consolidated over longer timescales, but it did not move in eight weeks; an intervention aimed at sensory and bodily representation is an untested implication (Two-factor model of relapse vulnerability).
- Cross-sectionally, mindfulness graduates kept the insula engaged under a sad-film challenge where controls deactivated it (Farb et al. (2010)).
What would answer it
- Randomise remitted patients at high relapse risk to a body-focused intervention (for example Mindful Awareness in Body-oriented Therapy (MABT) or interoceptively emphasised training) or a cognitive prophylactic therapy, scan before and after under dysphoric induction and the Self-Referential Encoding Task (SRET), and test whether somatosensory deactivation changes more in the body-focused arm and whether that change predicts relapse over two years.

The Two-factor model of relapse vulnerability splits relapse risk into a dynamic prefrontal factor that therapy moves and a static sensory factor that it does not. The page calls this the model’s sharpest open problem: if the deeper vulnerability is treatment-invariant, prophylactic therapy leaves it intact.
Wu et al. (2026) shifted the weight further towards the sensory side. Their protective, treatment-responsive marker was itself somatosensory, and in the combined model the prefrontal marker dropped out. Their conclusion, that relapse reflects insufficient recruitment of somatosensory systems supporting embodied self-experience, is a direct argument for treating that recruitment as a target.
Neither trial included a treatment designed to act on bodily representation; both arms were cognitive in emphasis. The wiki’s body-awareness applications (Interoceptive training in clinical practice, contemplative interoceptive training for well-being, Mindful Awareness in Body-oriented Therapy (MABT)) implicitly propose exactly that, so the needed study is a head-to-head trial with the same imaging markers used as outcomes.
