The controversy about cognitive behavioural therapy for schizophrenia

What Constitutes Sufficient Evidence for Case Formulation–Driven CBT for Psychosis? Cumulative Meta-analysis of the Effect on Hallucinations and Delusions

“…The question of whether CBTp “works” is no longer central, while previous disputes appear to have been settled. 6 Further development of RCTs examining novel approaches such as culturally adapted CBTp and VR-CBTp will allow clearer conclusion on their efficacy via increased power in meta-analysis including only these interventions. We also note that RCTs examining novel approaches typically provide briefer interventions, although our post hoc analysis did not suggest a significant impact of treatment duration on outcome.…”

“…These include trials employing the typical implementation of individually case-formulated CBTp in Western mental health care systems as were prevalent in the former review alongside a range of trials in new settings and/or employing new styles of intervention, eg, culturally adapted CBTp in Pakistan 4 or virtual-reality-based CBTp. 5 There remains well-documented controversy 6 over the effectiveness and implementation of CBTp; both the UK National Institute for Health and Care Excellence 7 and the British Psychological Society Understanding Psychosis and Schizophrenia report 8 recommend CBTp, whereas the Cochrane Collaboration maintain that meta-analytic results are neither clear nor robust enough to recommend CBTp over standard care. 9 Recent literature addressing this controversy argues the importance of attending to methodological issues including blinding, inclusion criteria and pre-specification of methods.…”

Efficacy and Moderators of Cognitive Behavioural Therapy for Psychosis Versus Other Psychological Interventions: An Individual-Participant Data Meta-Analysis

“…The efficacy of psychological interventions for psychosis have been established (1)(2)(3)(4)(5) while counter-argument questioning effectiveness exists (6,7). Meta-analytic studies represent the pinnacle of evidence-based psychological intervention in psychosis.…”

Improving treatments for psychotic disorders: beyond cognitive behaviour therapy for psychosis

“…However, studies have repeatedly shown that at least a third of patients, possibly up to two thirds of patients (Samara, Nikolakopoulou, Salanti, & Leucht, 2019), will show inadequate response to antipsychotic medication (Andreasen et al, 2005;Kane, Honigfeld, Singer, & Meltzer, 1988;Lehman, et al, 2004). Psychological treatments do not fare much better McKenna, Leucht, Jauhar, Laws, & Bighelli, 2019). A 2014 meta-analysis found end of treatment effect sizes that were uniformly in the small range (0.13-0.33) (Jauhar et al, 2014).…”
