Effectiveness of Music Video on HIV/AIDS Prevention among Female Factory Workers in Lao PDR

Background: Socio-economic development has led to rapid changes in young people’s lifestyle and sexual behaviour in Lao PDR. HIV/AIDS education provided at school is not sufficient, therefore, developing effective educational methods is necessary. The purpose of this study was to develop an Entertainment-Education Music Video using ‘Lam’, Lao traditional folk song (EEMVL) and evaluate its effectiveness. 
Methods: Experimental study was conducted at a factory in southern part of Laos. Factory workers received HIV/AIDS education by watching EEMVL. Fifty-one female factory workers were completed semi structured questionnaires at pre and post intervention, and at a two-week follow-up. The questionnaire was included items about knowledge and awareness of HIV/AIDS, self-efficacy of condom use, intention of condom use, positive and negative attitude to people living with HIV/AIDS. 
Results: The results showed increased self-efficacy of condom use (p<0.001), reduced negative attitude towards people living with HIV/AIDS (p=0.003) and improved communication on HIV/AIDS information among factory workers (p<0.001) from pre intervention to two-week follow-up. Intention of condom use was increased from pre to post (p=0.017), however, decreased at the two-week follow-up (p=0.02). This decreased intention was due to the participant’s understanding of the importance of gaining the skills to protect oneself from HIV infection, and realizing that condoms cannot give 100% protection against HIV infection. Moreover, the participants expressed their desire to preserve Lao culture against HIV/AIDS and to fulfil their responsibility as Lao nationals. 
Conclusion: These results suggested that the social modelling behaviour demonstrated in the EEMVL led the audience to improve their health literacy on HIV/AIDS prevention and stimulated interpersonal communication among the participants.
