Meta-analyses of the neural mechanisms and predictors of response to psychotherapy in depression and anxiety
Open accessAbstract
Understanding the neural mechanisms underlying psychological therapy could aid understanding of recovery processes and help target treatments. The dual-process model hypothesises that psychological therapy is associated with increased emotional-regulation in prefrontal brain regions and decreased implicit emotional-reactivity in limbic regions; however, research has yielded inconsistent findings. Meta-analyses of brain activity changes accompanying psychological therapy (22 studies, n = 352) and neural predictors of symptomatic improvement (11 studies, n = 293) in depression and anxiety were conducted using seed-based d mapping. Both resting-state and task-based studies were included, and analysed together and separately. The most robust findings were significant decreases in anterior cingulate/paracingulate gyrus, inferior frontal gyrus and insula activation after therapy. Cuneus activation was predictive of subsequent symptom change. The results are in agreement with neural models of improved emotional-reactivity following therapy as evidenced by decreased activity within the anterior cingulate and insula. We propose compensatory as well as corrective neural mechanisms of action underlie therapeutic efficacy, and suggest the dual-process model may be too simplistic to account fully for treatment mechanisms. More research on predictors of psychotherapeutic response is required to provide reliable predictors of response.

TL;DR
This paper reports AES-SDM meta-analyses of functional neuroimaging studies of psychotherapy in depression and anxiety. It found robust pre-to-post decreases in ACC, inferior frontal gyrus and insula, but only limited robust pre-treatment predictors of symptomatic improvement.
Key findings
- In 22 longitudinal studies (n = 352 patients), psychological therapy was associated with significantly decreased activation post- versus pre-therapy in the left ACC/paracingulate gyri, right inferior frontal gyrus, and left inferior frontal gyrus/insula (all ps < .0001); these were the most robust results with no evidence of publication bias.
- The prediction meta-analysis included 11 studies (n = 293 patients); only one cluster survived jackknife sensitivity analysis: greater baseline right cuneus cortex activation was associated with greater symptomatic improvement (p = .0004, peak MNI 10, −92, 14).
- Other prediction clusters were not robust, and all prediction clusters showed evidence of publication bias in funnel plots, with an Egger’s regression trend for the decreased-activation cluster (t(1, 10) = −2.17, p = .055).
- Subgroup analyses showed substantial task versus resting-state differences; decreased ACC activity post-therapy was common across both paradigms, while the only resting-state cluster surviving all robustness tests was the right middle frontal gyrus (p = .00005, peak 48, 34, 18).
Methods
- Literature searches were conducted in Scopus, PubMed, and Medline for articles published before 24.07.2017; 33 articles were suitable for inclusion. Eligible studies used MRI, SPECT, or PET, included adults with DSM/ICD diagnoses of depression or anxiety disorders, reported whole-brain peak coordinates, and examined either pre-to-post therapy activation changes or pre-treatment predictors of symptom improvement.
- Analyses used anisotropic effect-size seed-based d mapping (AES-SDM); voxels with p < .005 were considered significant, clusters with fewer than 10 voxels or peaks with AES-SDM Z-values < 1 were discarded, and jackknife sensitivity analysis, funnel plots, and Egger regression were used to assess robustness and publication bias.
- Longitudinal and prediction meta-analyses were run separately, and task-based versus resting-state studies were analyzed separately where the number of studies permitted; meta-regressions for disorder, medication, or therapy type were not possible due to too few studies.
Limitations
- The paper states that the literature is small, so between-study heterogeneity other than paradigm type could not be assessed through meta-regressions; included studies varied in paradigm, disorder, comorbidity, severity, therapy type, medication status, and imaging modality (fMRI, PET, SPECT), and anxiety disorders were over-represented compared with depression.
- The paper states that only patient groups receiving therapy were included, so effects may partly reflect spontaneous remission or concomitant therapy rather than treatment alone; inclusion of placebo or wait-list control arms was not within scope.
- The paper states that publication bias was evident in the prediction meta-analysis, and reliance on published peak coordinates does not provide the detail of statistical parametric maps or individual-level data; the text also makes evident that several longitudinal clusters were driven by only one or two studies.

Each contradiction between two passages listed here was confirmed by an independent check.
Precuneus finding is said to lack publication bias despite its funnel plot
MajorThe task-based results describe the precuneus finding as showing no signs of publication bias, whereas the note for that cluster in Table 3 says its funnel plot showed signs of publication bias.
“The most robust findings were the precuneus increased activation (p = .0002, peak coordinates: 6, −56, 38) and ACC deactivation (p = .0001, peak coordinates: −8, 44, −2) post-therapy, which showed no signs of publication bias.”
“1 Driven by one study: Goldin et al. (2012) and funnel plot showed signs of publication bias.”
Left inferior frontal/insula cluster is called robust despite not passing all robustness tests
MinorThe results call this one of the most robust clusters with no evidence of publication bias, but Table 2 marks only the ACC and right inferior frontal clusters as surviving all robustness and publication-bias tests. The left inferior frontal/insula cluster is not marked.
“The most robust results, with no evidence of publication bias, were that psychological therapy was associated with significantly decreased activity post- compared to pre-therapy, in the left ACC/paracingulate gyri, the right inferior frontal gyrus and left inferior frontal gyrus/insula (all ps<.0001)”
“*Clusters surviving all tests of robustness and publication bias.”
Longitudinal meta-analysis is said to show no publication bias despite reported signs
MinorThe limitations section says the longitudinal meta-analysis showed no evidence of publication bias. Table 2, however, reports funnel-plot evidence or signs of publication bias in several longitudinal clusters.
“Although, in our longitudinal meta-analysis, we did not show any evidence of this, there were signs of publication bias in the prediction of treatment response meta-analysis.”
“1 Driven only by two studies Goldin and Gross (2010) and Yamanishi et al. (2009) and funnel plots showed evidence of publication bias in this cluster.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
