Hypotheses: 1)Youth receiving the motivational intervention plus referrals will report greater reductions in risky behaviors than youth in the control group receiving standard care plus referrals at 3-months post-baseline. This hypothesis will first be tested in the whole sample using an overall risk index. Then, the hypothesis will be tested with each behavior (reduced drug and alcohol use, condom use, taking medications,) within the subgroups reporting problem levels of that behavior; 2)Youth in the intervention group will demonstrate improved viral loads, will report greater improvement in perceived health status, depression, general psychological distress, disclosure to sexual partners, and will demonstrate greater attendance of medical and support service appointments than youth in the control group at 3 months post-baseline; 3)Youth in the intervention group will report greater reductions in temptation to engage in risky behaviors, increased self-efficacy, and improvements in readiness to change their behavior than youth in the control group at 3 months post-baseline; 4)The differences between the intervention and control group from pre- to post- intervention will be maintained at 6, 9, 12, and 15 months post-baseline (3, 6, 9, and 12 months after intervention completion).
