Dating violence (DV) is a major public health problem among youth. The majority of DV studies in Taiwan involve the assessment of DV without the use of a robust psychological framework to guide research accuracy. Therefore, the purpose of this study was to utilize the Theory of Planned Behavior (TPB) to assess intention and other salient factors related to DV among university students. A two-phase, mixed-method design study was conducted among university students from seven universities in Taiwan, aged 18 to 24 years. In Phase I, questionnaires used were specifically developed based on the TPB, consisting of both direct and indirect measures related to DV. In Phase Ⅱ, questionnaire evaluation and related factors were examined through a two-step process of structural equation modelling (SEM) to test the TPB model. The results of this study found that perceived behavioral control, subjective norm, and attitude toward DV on behavioral intention accounting for 37.5% of the total variance. Among the related factors, attitude toward the behavior was the strongest (β = 0.48, p < 0.001), followed by perceived behavioral control (β = 0.19, p < 0.05). Findings from this study could expand the knowledge base in this important area and might help prevent DV.

Dating violence (DV) constitutes a major public health and safety issue worldwide; however, only limited research into this important subject has been conducted in Taiwan. This study examined university students’ intention to commit DV, based on the expanded theory of planned behavior (TPB), with a history of family violence and gender stereotyping also included as further factors in the original TPB model. A total random sample consisting of 450 university students from four universities in four regions in Taiwan, namely, the northern, southern, central, and eastern regions, participated. Of these participants, 365 (81.1%) completed all of the parts of the questionnaires, which included a survey of demographic data, such as any history of family violence; a gender stereotyping questionnaire; and a DV behavioral intention questionnaire. The results showed that the three main variables of the TPB—that is, subjective norms, attitudes, and perceived behavioral control—significantly related to university students’ intentions to commit DV. More specifically, university students’ attitudes and subjective norms emerged as significant related factors of their intention to commit DV behaviors. Overall, the expanded TPB explained 30.4% of the variance in DV intentions, and attitude was the most significant factors after controlling the background variables. These findings can hopefully be used to help design and implement programs for the prevention of DV behaviors among university students.

The aims of this study were to examine gender differences in how parent–child discussions on sex issues, peer interactions around sexual issues, and exposure to sexually explicit materials affect the intention to engage in casual sex among adolescents and young adults in Taiwan. This cross-sectional survey study recruited 767 participants (348 men and 419 women) aged 15–24 years. The survey collected data on participants’ intention to engage in casual sex, their attitude toward and perception of casual sex based on the theory of planned behavior (TPB) (favorable attitude, perceiving positive social norms toward casual sex, and perceived control over involvement), parent–child and peer discussions about sexual issues, and exposure to sexually explicit materials. The results of multiple regression analysis revealed that parent–child discussions on sex issues, peer interactions around sexual issues, and exposure to sexually explicit materials were significantly associated with the intention to engage in casual sex. The results of structural equation modeling (SEM) further supported that favorable attitude, perceiving positive social norms toward casual sex, and control over involvement mediated the associations. For men, decreased favorable attitude mediated the negative association between parent–child discussions and casual sex intention; increased favorable attitudes and decreased control over involvement mediated the positive associations between peer interactions and casual sex intention. For women, decreased control over involvement mediated the positive association between exposure to sexually explicit materials and casual sex intention. The associations between peer interaction and subjective norms of acceptance, perceived control over involvement, and casual sex intention were stronger in men than in women; the association of favorable attitudes with casual sex intention was also stronger in men than in women.
