Patient experience of negative effects of psychological treatment: results of a national survey
Open accessAbstract
Background: To make informed choices, patients need information about negative as well as positive effects of treatments. There is little information about negative effects of psychological interventions. Aims: To determine the prevalence of and risk factors for perceived negative effects of psychological treatment for common mental disorders. Method: Cross-sectional survey of people receiving psychological treatment from 184 services in England and Wales. Respondents were asked whether they had experienced lasting bad effects from the treatment they received. Results: Of 14 587 respondents, 763 (5.2%) reported experiencing lasting bad effects. People aged over 65 were less likely to report such effects and sexual and ethnic minorities were more likely to report them. People who were unsure what type of therapy they received were more likely to report negative effects (odds ratio (OR) = 1.51, 95% CI 1.22–1.87), and those that stated that they were given enough information about therapy before it started were less likely to report them (OR = 0.65, 95% CI 0.54–0.79). Conclusions: One in 20 people responding to this survey reported lasting bad effects from psychological treatment. Clinicians should discuss the potential for both the positive and negative effects of therapy before it starts.

Psychological and behavioural therapies may on occasion confer deterioration and harm.
“While assumed to be exclusively beneficial, psychological, and behavioural therapies may on occasion confer deterioration and harm [104,105,106].”
Crawford et al. (2016) found that in a survey of over 14,000 UK NHS psychological therapy patients, just over 5% reported lasting bad effects of treatment.

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.
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.
