Abstract

Background: Multiple risk behaviors (MRB) among adolescents are correlated with adverse health
outcomes. We have devised and examined the effect of a mobile application, STOP Multiple Risk
Behaviors (“STOPMRB”), on perceived behavioral control and intention to avoid multiple risk
behaviors (MRB) among Thai female adolescents.
Methods: We conducted a two-group pre-post-test, quasi-experimental study involving Thai female
adolescents aged 13–15 (N=60) in Samut Prakarn province, Thailand, between March and May
2021. Participants selected for the intervention group (N=30) were provided with access to a mobile
application in conjunction with text messages for 8 weeks, whereas the control group (N=30) received
standard education curricula. The primary outcome was self-reported risk behaviors. Secondary
outcomes encompassed perceived behavioral control and intention to avoid MRB. Outcomes were
analyzed using repeated measures ANOVA, Bonferrini test, Fisher’s Exact test, and independent t-test
through the software IBM SPSS version 28. A significance level was established at a P-value of less
than 0.05.
Results: Following a two-month intervention, no MRB was reported among the intervention group,
whereas the control group showed 6.7% (P=0.492). The intervention group demonstrated significantly
higher mean scores of perceived behavioral control (P<0.001) and the intention to avoid (P<0.001) in
comparison to the control group at weeks 4 and 8.
Conclusion: Mobile application, according to STOPMRB, could enhance perceived behavioral control
and intention to evade MRB and less self-reported frequency of MRB.
