Comparison 1: CBT‐based psychotherapy probably leads to lower repetition of SH at 6 months compared with treatment (moderate certainty).
Comparison 1: CBT‐based psychotherapy probably leads to lower repetition of SH at 12 months compared with treatment (moderate certainty).
Comparison 1: CBT‐based psychotherapy probably leads to lower repetition of SH at 24 months compared with treatment (moderate certainty).
Comparison 1: CBT‐based psychotherapy may leads to lower repetition of SH at final compared with treatment (low certainty).
Comparison 1: Individual CBT‐based psychotherapy showed no clear difference in repetition of SH by post‐intervention compared with TAU or other comparator (low certainty).
It is very uncertain whether comparison 1: individual CBT‐based psychotherapy changes repetition of SH at six months compared with treatment (very low certainty).
It is very uncertain whether cognitive behavioural therapy and other therapies changes arrested for any crime at 6 months compared with prison therapeutic community (very low certainty).

It is very uncertain whether cognitive behavioural therapy and other therapies changes drug‐related crime at 6 months compared with prison therapeutic community (very low certainty).
It is very uncertain whether cognitive behavioural therapy and other therapies changes arrested (not parole violation) at 6 months compared with prison therapeutic community (very low certainty).
It is very uncertain whether cognitive behavioural therapy and other therapies changes self‐reported drug use at 6 months compared with prison therapeutic community (very low certainty).
Cognitive behavioural therapy and other therapies showed no clear difference in reincarcerated at 12 months after parole compared with prison therapeutic community (low certainty).
It is very uncertain whether cognitive behavioural therapy and standard therapy changes incarceration at 3 months compared with treatment (very low certainty).
Comparison 1.2: Group‐based CBT‐based psychotherapy showed no clear difference in repetition of SH at post‐intervention compared with TAU or another comparator (moderate certainty).
Comparison 1.1: Individual‐based CBT‐based psychotherapy showed no clear difference in repetition of SH at post‐intervention compared with TAU or another comparator (low certainty).
Cognitive behavioural therapy + motivational interviewing showed no clear difference in leaving the study early: Lost to treatment compared with standard care (low certainty).
Cognitive behavioural therapy + motivational interviewing showed no clear difference in adverse event: Death compared with standard care (low certainty).
