Quantum changes in self-efficacy and condom-use intention among youth: A chained cusp catastrophe model.
J Adolesc 2018; 68:187-197JA

Abstract

INTRODUCTION

The complex relationships among HIV knowledge, condom-use skills, self-efficacy, peer influence and intention to use condoms have been rigorously investigated. However, studies guided by a linear behavior change model often explain only a limited amount of variances. This study aims to advance our understanding of the relationships through a nonlinear quantum change paradigm.

METHODS

Data (n = 1970, 40.61% male, mean age 16.94 ± 0.74) from a behavioral intervention program among high school students in the Bahamas were analyzed with a chained cusp catastrophe model in two steps. In the first step, self-efficacy was analyzed as the outcome with HIV knowledge/condom-use skills as asymmetry variables and peer influence as bifurcation variable. In the second step, condom-use intention was analyzed as the outcome while self-efficacy (outcome in the first step) was used as bifurcation variable allowing peer influence as bifurcation, and HIV knowledge/condom-use skills were included as asymmetry. Cusp modeling analysis was conducted along with equivalent linear models.

RESULTS

The cusp model performed better than the linear and logistic models. Cusp modeling analyses revealed that peer influence significantly bifurcated the relationships between HIV knowledge/condom-use skills and self-efficacy; while both self-efficacy and peer influence significantly bifurcated the relationship between HIV knowledge/condom-use skills and condom-use intention.

CONCLUSION

Our findings support the central role of self-efficacy and peer influence as two chains in bridging the complex quantum relationships between HIV knowledge/condom-use skills and condom-use intention among adolescents. The nonlinear cusp catastrophe modeling provided a new method to advance HIV behavioral research.
