(2014) utilised the Theory of Planned behaviour (TPB) to formulate the variables within the cross-sectional questionnaire respondents filled out. They addressed social norms, descriptive norms and subjective norms to find out what influences are involved addressing the socio-cognitive processes in the decision making of behavioural choices whether or not to use a condom. These covered marital status, age, gender, sexuality, gender, their sexual history, condom use at first intercourse and condom failure. Condom use intentions and recent condom use were the two outcome variables (Thomas et al., 2014). Attitudes, self-efficacy, descriptive social norms and the willingness of a partner to use a condoms was also measured. Broaddus et al. (2011) reported this study utilising TPB to measure socio-cognitive process to gain understanding of the impact this has on behaviour. It also identifies the stability of intentions and how this will differ by gender using the TPB model. Armitage et al. (2010) reported that TPB was used to test interventions designed to change variables within the model; perceived behavioural control, subjective norm and attitude regarding socio-cognitive process towards safe …show more content…
They all presented that the model was useful in predicting intentions with one article indicating that the model was unable to successfully explain safe sex intentions and behaviours by way of utilising the TPB. The use of the TPB in this study reported by Thomas et al. (2014) is favourable, it has shown to have a good predictive validity, to determine the positive outcome for the use of the TPB model to explain safe sex intentions and behaviours, in which carrying a condom is the key target in the study as this has an importance of health behaviour and an intention to perform safe sex. This has also aided in understanding the socio-cognitive processes relating to intervention. To further support the TPB the health behaviour in deciding to carry a condom is a function responding to social norms, which aids in the intervention. In this longitudinal study Broaddus et al. (2011) reported that earlier studies indicated weakness in the TPB. The constructs were a concept that were
