This study has perhaps for the first time in the Indian context made an attempt to use a psychosocial model for a HIV/AIDS intervention programme. In line with the same, the main objective of the research was to study the effect of the information, motivation and behavioural skills (IMB) model-based intervention on a group of female college/university students. Purposive sampling was used to select 200 participants; pre-testing of these participants revealed that they did not have adequate information on issues related to HIV transmission and prevention. Further, neither were they motivated nor possessed appropriate behavioural skills to engage in HIV preventive behaviours. Following this, 100 participants were assigned to the experimental group and the remaining 100 to the control group. Post-testing showed a significant increase in the level of information, motivation and behavioural skills of the experimental group participants who underwent the three-session intervention programme as compared to the control group participants.
