This study analyzes a structural model which investigates causality among factors. Using a hypothetical model on the reproductive health behavior of single women with sexual experience, the model’s suitability was assessed based on Ajzen’s (1991) Theory of Planned Behavior (TPB). The factors used in this study include attitude based on the TPB, subjective norm, perceived behavioral control, intention and reproductive health behavior. Based on these factors, a hypothetical model was developed, and its suitability and significance of both direct and indirect paths were verified. In terms of data collection, data were collected and analyzed after getting consent from a total of 250 single women (aged 20-29) with sexual experience selected by a domestic online research firm from August 26 to September 10, 2015. For data analysis, SPSS 18.0 and AMOS 18.0 were used.
The study results found the following:
1) In terms of model suitability, absolute fit measures (RMR, RMSEA, GFI), incremental fit measures (TLI, CFI, IFI) and parsimonious fit measures revealed a good goodness-of-fit, satisfying the related requirements. Therefore, the hypothetical model was chosen as a final model without corrections.
2) In terms of a factor having a direct effect on the behavior of single women with sexual experience, “attitude” was observed, and it had the biggest effect on productive health behavior. In terms of factors having a direct effect on intention, “attitude,” “subjective norm” and “perceived behavioral control” were found. Among them, “perceived behavioral control” revealed the largest influence.
3) Among a total of eight paths set in a hypothetical model, statistical significance was detected in seven paths. In terms of intention, 77.2% was explained in “attitude,” “subjective norm” and “perceived behavioral control”. In terms of reproductive health behavior, 27.8% was stated in “attitude”, “subjective norm”, “perceived behavioral control” and “intention”.
The results confirmed that the TPB is a suitable model in explaining the reproductive health behavior of single women with sexual experience. It is expected that they would be available as basic data in searching for a strategic plan for educational and intervention programs aimed to encourage single women to engage in reproductive health behavior.
