DescriptionThis study developed and tested theory to gain a better understanding of smoking behavior among older adolescents. This correlational study empirically tested theoretical relationships postulated between the dependent variable, smoking behavior and each of the independent variables of (a) depression, (b) social support and (c) smoking resistance self efficacy. This study also tested the relationship of smoking resistance self efficacy and (a) social support and (b) depression. In addition, this study examined two mediational models, which tested the role of smoking resistance self efficacy as a mediator in the relationship of (a) social support and smoking behavior, and (b) depression and smoking behavior.
A convenience sample of 364 college students 18-21 years of age was recruited from a large urban public college in the South Eastern region of New York State. Volunteers completed the study instrument which consisted of a demographic data sheet and three standardized instruments.
There were statistically significant negative relationships between smoking resistance self efficacy and (a) smoking behavior, and (b) depression. There was a statistically significant positive relationship between depression and smoking behavior. Additionally, smoking resistance self efficacy was a mediator of the relationship between depression and smoking behavior. The study did not provide evidence of a statistically significant relationship between (a) smoking behavior and social support and (b) smoking resistance self efficacy and social support. Smoking resistance self efficacy failed to act as a mediator of the relationship between social support and smoking behavior.
In summary, this study contributes to theory based nursing research in determining the role of SSE as (1) a mediator of the relationship between smoking behavior and depression, and (2) a strong correlate of smoking behavior. Through the explication of SSE as mediator of the relationship between depression and smoking behavior, this study invites further nursing research, specifically those employing interventions designed to enhance SSE. The findings of this study have implications for nursing interventions targeted to both current smokers and smoking initiation prevention. In addition, this research identifies a need for further theory-driven study of the relationship of depression and smoking behavior among adolescents.
