BCSS: Brief Core Schema Scales; CBT: cognitive behavioural therapy; CI: confidence interval; LOCF: last‐observation‐carried‐forward; n: number of participants; SD: standard deviation; TAU: treatment as usual.

^aTrial investigators have used a last‐observation‐carried‐forward procedure (i.e. endpoint scores based on last available value).
