The TPB suggests that attitudes, perceived behavioural control and subjective norm are direct predictors of

infidelity intention. A sample of 160 university students was employed, with female and male ratio 93 and 67,

consecutively. It is expected that individual?s favourable attitudes toward infidelity increase the likelihood of

one?s unfaithful behaviour. Infidelity intention tend to be higher if individuals perceived that their surroundings

approved infidelity behaviour, and also if they believe that cheating on partner is easy for them. Additionally,

relationship satisfaction will also be examined as another predictor of infidelity intention. It is expected that

individuals with greater relationship satisfaction will be less likely to engage in infidelity behaviour., This study investigated infidelity intention among dating relationships using theory of planned behaviour (TPB).
