A Study on the Application of the Information-Motivation-Behavioral Skills (IMB) Model on Rational Drug Use Behavior among Second-Level Hospital Outpatients in Anhui, China

Abstract

BackgroundThe high prevalence of risky irrational drug use behaviors mean that outpatients face high risks of drug resistance and even death. This study represents the first application of the Information-Motivation-Behavioral Skills (IMB) model on rational drug use behavior among second-level hospital outpatients from three prefecture-level cities in Anhui, China. Using the IMB model, our study examined predictors of rational drug use behavior and determined the associations between the model constructs.MethodsThis study was conducted with a sample of 1,214 outpatients aged 18 years and older in Anhui second-level hospitals and applied the structural equation model (SEM) to test predictive relations among the IMB model variables related to rational drug use behavior.ResultsAge, information and motivation had significant direct effects on rational drug use behavior. Behavioral skills as an intermediate variable also significantly predicted more rational drug use behavior. Female gender, higher educational level, more information and more motivation predicted more behavioral skills. In addition, there were significant indirect impacts on rational drug use behavior mediated through behavioral skills.ConclusionsThe IMB-based model explained the relationships between the constructs and rational drug use behavior of outpatients in detail, and it suggests that future interventions among second-level hospital outpatients should consider demographic characteristics and should focus on improving motivation and behavioral skills in addition to the publicity of knowledge.

Modeling a Theory-Based Approach to Examine the Influence of Neurocognitive Impairment on HIV Risk Reduction Behaviors Among Drug Users in Treatment

“…Overall, the results provide further support for the IMB model of HIV prevention behavior (36, 38, 42). The findings confirm the model’s central proposition that both information and motivation work through behavioral skills to affect HIV prevention behavior (34).…”

“…In both the drug-related and sex-related HIV risk reduction domains that we modelled, the strength of the partial mediation effect decreased in conjunction with levels of NCI: HIV risk reduction behavioral skills (demonstrated needle cleaning and condom application) tended to translate gains in information and motivation into HIV preventive behavior (clean needle use and condom use), particularly among individuals without high levels of NCI, as they appeared more likely to benefit from the information and skills components that were conveyed by the intervention (18, 19). Hence, this pattern of findings might at least partially explain the variation in prior studies regarding the mediating role of behavioral skills between HIV risk reduction information, motivation, and HIV preventive behavior (36–38, 42, 43, 45, 49, 64). …”

“…An application of health behavior change theory to HIV prevention among PWUDs can help researchers to identify the critical dynamics of this particular population HIV risk behaviors in need of targeted intervention efforts, and to empirically evaluate the ability of these theories to predict and promote prevention behavior. The theoretical approach used for this analysis is the Information-Motivation-Behavioral Skills model of health behavior change (IMB) (34, 35) – a theoretical model, which has been successfully applied to the design and evaluation of a wide range of intervention approaches targeting various patient populations and diseases (14, 36–41). …”

Willingness to Use Pre-Exposure Prophylaxis (PrEP): An Empirical Test of the Information-Motivation-Behavioral Skills (IMB) Model among High-Risk Drug Users in Treatment

“…While the IMB model has been successfully utilized as a theoretical framework for the design and evaluation of a wide range of intervention strategies across different behaviors, populations, and contexts [30–37], it has not yet been applied to PrEP usage. In the present study, we therefore tested a theory-based model using constructs from the IMB model [28, 29] and applied it to PrEP use as HIV prevention among opioid-dependent persons at risk for HIV.…”
