Input: There were minimal differences identified between multi-session psychosocial interventions and standard educational interventions for both injection and sexual risk behaviour. Although it should be noted there were large pre-post changes for both groups suggesting both were effective in reducing risk behaviours. In addition, there was some evidence of benefit for multi-session psychosocial interventions when compared with minimal controls. Subgroup analyses suggest that people in formal treatment are likely to respond to multi-session psychosocial interventions. It also appears single-gender groups may be associated with greater benefit. There is limited support for the widespread use of formal multi-session psychosocial interventions for reducing injection and sexual risk behaviour. Brief standard education interventions appear to be a more cost-effective option. Further research is required to assess if there are particular groups of drug users more likely to respond to such interventions.
Output:

There were 35 trials on 11,867 participants that examined whether these interventions are effective in reducing sexual and injection behaviour associated with greater risk of developing HIV. There are not large differences in effectiveness between multi-session psychosocial interventions and briefer interventions. This suggests brief educational interventions are more likely to be cost-effective and may be more readily implemented in a variety of different contexts.
