Negative effects of psychotherapies for adult depression: A meta-analysis of deterioration rates
Open accessAbstract
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.

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
MinorThe 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.
“Wuthrich, 2013 clin sign deterioration b) 1.30 0.08~19.800.85 1/27 1/35 0.01 -0.10~0.08”
“The risk difference (RD) between psychotherapy and control groups, which indicates the risk of deterioration in the control groups minus the risk in the psychotherapy groups, was RD = 0.05”
Watt study risk difference does not match its event counts
MinorBoth 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
“Watt, 2000 -instr clin sign deterioration b) 0.22 0.02~2.700.24 0/9 2/9 0.28 -0.07~0.62”
Table 3 reverses the reporting-group columns
MinorTable 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 Table 3 Differences between randomised controlled trials on psychotherapy for adult depression that report negative effects (N = 23) and those that do not (N = 346) report negatieve effects.)Differences between studies were tested with Chi-square tests for all variables, except for number of sessions, risk of bias and year of publication; these are continuous variables and therefore tested with t-tests.”
“Recruitment | Community | 45.1 (156) | 69.6 (16) | 46.6 (172) 0.06 | |”
Table 3 assigns too many comparisons to general-adult studies
MinorThe 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.
“| Target group | Adults | 53.5 (185) | 60.9 (14) | 53.9 (199) 0.49 | |”
“A total of six studies were aimed at adults in general and 12 at other more specific target groups.”

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.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-05.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-05.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
