Abstract

Background The risk for deterioration in patients receiving psychotherapy for adult depression has not been examined extensively and it is not clear whether psychotherapy reduces this risk or may even increase it in some patients. We conducted a meta-analysis of trials comparing these psychotherapies with control conditions that report deterioration rates.Methods We used an existing database of randomized trials on psychotherapies for adult depression which was updated up to 1/1/2017, through systematic searches in bibliographic databases. We included trials that reported clinically significant deterioration rates.Results We included 18 studies with 23 comparisons between therapy and control groups. The pooled risk ratio of deterioration was 0.39 (95% CI: 0.27∼0.57), indicating that patients in the psychotherapy groups have a 61% lower chance to deteriorate than patients in the control groups. We found that 20 patients need to be treated with psychotherapy in order to avoid one case of deterioration, compared to the control conditions. The median deterioration rate in the therapy groups was 4%, and in some studies more than 10%, indicating that clinicians should always be aware of the risk of deterioration.Limitations The results should be considered with caution because most studies had at least some risk of bias. Only 6% of all trials comparing psychotherapy with a control condition reported deterioration rates, using different ways to define deterioration which made pooling the prevalence rates across treatments and control groups impossible.Conclusions Psychological treatments of adult depression may reduce the risk for deterioration, compared to control groups, but this should be considered with caution because of the small proportion of studies reporting deterioration rates.

  • The proportion of individuals experiencing symptom deterioration during face-to-face psychological interventions is estimated to range between 3-14%, comparable to deterioration rates for online interventions.

    “Although deterioration rates are infrequently reported in the literature, the proportion of individuals experiencing symptom deterioration during face-to-face psychological interventions is estimated to range between 3-14% (Ebert et al., 2016; Cujipers et al., 2018; Ronk et al., 2013), which is comparable to deterioration rates for online interventions (Ebert et al., 2016).”

    From A randomised trial comparing a brief online delivery of mindfulness-plus-values versus values only for symptoms of depression: Does baseline severity matter? (2020) · cites this paper as Cujipers et al., 2018

    Section 3.4 reports symptom deterioration in psychotherapy groups, supporting the general point, but gives a range of 0–25% (median 4%), not 3–14%. The study-characteristics table in the Discussion includes internet-based as well as face-to-face treatments, so that range is not an estimate specifically for face-to-face interventions. The citing sentence attributes the comparison with online interventions to Ebert et al., not to this paper. (LLM, conf=0.88)

  • Deterioration rates (3.2% depression, 3.1% anxiety) were slightly lower but within the 95% CI of RCT findings for internet-based guided self-help (3.36% depression, 5.8% anxiety) and comparable with face-to-face psychotherapy for depression.

    “The results of deterioration rates (3.2% in depression and 3.1% in anxiety studies) were slightly lower, but within the 95% CI of findings based on RCTs for internet-based guided self-help interventions (3.36%) for depression [164] and anxiety (5.8% [165]), and also comparable with deterioration rates in face-to-face psychotherapy for depression [166].”

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Wuthrich risk difference has the opposite sign

    Minor

    The Wuthrich comparison has one deterioration in each group, but the psychotherapy group is smaller (27 versus 35), so its deterioration risk is higher. Under the paper's definition of control risk minus psychotherapy risk, the risk difference is negative, not positive 0.01.

  • Watt study risk difference does not match its event counts

    Minor

    Both Watt comparisons report zero deteriorations among nine psychotherapy patients and two among nine controls. With zero events in psychotherapy, the stated risk difference should equal the control risk, 2/9 = 0.222, rather than 0.28.

    Reported 0.28 · recomputed 0.222222

  • Table 3 reverses the reporting-group columns

    Minor

    Table 3 identifies the first group as the 23 comparisons reporting negative effects and the second as the 346 that do not. Its first numerical column nevertheless contains 156 community comparisons, which cannot belong to a group of 23; the numerical columns appear reversed.

  • Table 3 assigns too many comparisons to general-adult studies

    Minor

    The text says six of the 18 studies targeted adults in general. Since the 18 studies produced only 23 comparisons in total, those six studies could produce at most 11 comparisons, not the 14 assigned to the Adults category in Table 3.

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.
