mobile application intervention for prevention of multiple risk behaviors among thai female adolescents: a quasi-experimental study

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.
