Brief Summary
This randomized controlled trial will evaluate the efficacy of a Transtheoretical Model (TTM)-based behavior-change intervention, delivered through stage-matched counseling sessions, on anabolic-androgenic steroid (AAS) use among gym-goers, compared with a control group receiving standard health education. Non-medical AAS use is a growing public health concern in gym and fitness settings and is associated with serious cardiovascular, endocrine, hepatic, and psychiatric harms. Participants will be randomly assigned to either a TTM-based intervention group or a control group. The intervention will tailor counseling content to each participant's stage of change (precontemplation, contemplation, preparation, action, or maintenance) regarding AAS use. The findings of this study will provide evidence on the effectiveness of stage-based behavioral counseling in reducing AAS use and progressing gym-goers toward safer, drug-free training practices.

Outcome Measures
Primary Outcomes (2)
primary outcome meaure
Stage of change for anabolic-androgenic steroid use Stage of change will be assessed using a validated, AAS-adapted staging algorithm based on the Transtheoretical Model (precontemplation, contemplation, preparation, action, maintenance). This outcome will evaluate participants' readiness to reduce or discontinue AAS use. Forward stage progression indicates a positive treatment effect.
Baseline, immediately after completion of the assigned intervention (post-test 1), and 8 weeks after completion of the intervention (post-test 2).]
Change in Anabolic-Androgenic Steroid Use Behavior
The primary outcome is the change in anabolic-androgenic steroid use behavior from baseline to the end of the intervention, assessed using a validated questionnaire.
Baseline to 6 months after randomization
Secondary Outcomes (1)
Change Behavior
Immediately after completion of the assigned intervention (post-test 1) and 8 weeks after completion of the intervention (post-test
Study Arms (2)
TTM Intervention Group
EXPERIMENTALParticipants will receive an individualized, stage-matched behavioral counseling program targeting reduction and cessation of nonmedical anabolic-androgenic steroid use.
Control Group
ACTIVE COMPARATORParticipants will receive standard printed health education materials on the risks of anabolic-androgenic steroid use, without stage-matched counseling.
Interventions
Participants receive a standard pamphlet/handout describing the physical and psychological risks of AAS use, consistent with routine health promotion practice at the study site.

Data Sharing
- IPD Sharing
- Will not share
Individual participant data will not be shared because the study involves a relatively small sample from specific gym/fitness-center settings, and data sharing may increase the risk of participant identification even after de-identification.
