Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment was conducted from March 2004 to March 2006. Two types of participants were recruited: Index and Risk Network Members. Recruitment methods for Index included: street-based outreach, word of mouth, ads and referrals from community agencies. During the Index’s baseline interview, a list of Risk Network Members was generated.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Two types of participants were enrolled in the study- index and networks. Networks did not go through the intervention or control condition. Index participants had to refer a network member AND show up for randomization in order to be enrolled in the intervention or control condition.

Reporting Groups
  Description
Intervention Condition Index participants in the intervention condition were trained to be Health Educators. The intervention focused on HIV risk reduction by teaching knowledge and skills to reduce injection, drug splitting, and sex risk, and by teaching communication skills to conduct outreach to personal risk network members. The intervention consisted of five group-based sessions, one individual session, and one dyad session with a risk network member.
Control Condition Index participants in the control condition attended groups that focused on injection drug-use related topics (e.g. HIV testing, Hepatitis C and drug overdose). The sessions were educational and did not include skills training. The control condition consisted of five group-based sessions.
Non-Randomized Baseline Index Participants Those Index participants that completed a baseline interview but were not randomized into the intervention or control condition.
Risk Network Members Individuals from the personal social networks of the index participants who inject or are the sexual partners of the index participant

The discrepancy between participant flow and number of participants analyzed is due to missing data and skip patterns employed during data collection.
