peer interventions

Hier is een stukje uit een onderzoek naar peer interventions over wat voor een effect ze hebben op oa. condoom gebruik en drugs.

CONCLUSIONS:

These findings show that the use of peers as role models in promoting HIV risk reduction is feasible and effective among out-of-treatment drug abusers, particularly for drug use itself. Condom use was found to be more difficult to change than other behaviors. Possible reasons for this lack of improvement and suggestions for future interventions are given.

drugs
80% of the sample "improved" their crack cocaine use, meaning they maintained at low level or reduced their use.

sex partners
As for the number of sex partners, 75% of the overall sample improved; that is, they reduced the number of sex partners or remained abstinent or in a one-partner relationship at baseline and follow-up. There was no statistically significant difference between the enhanced and standard groups (76% vs 73%).

condoom gebruik
In terms of condom use, the overall sample worsened more than it improved (65% vs. 44%), and no differences were found between the enhanced and standard groups.
