The current PhD thesis aimed to cross-culturally investigate the effectiveness of gain- and loss-framed physical activity messages among the university students in Turkey and the UK. This study sought to test the impact of the physical activity messages focusing on stress-related effects on physical activity intentions, attitudes and behaviours of the target group. The messages were developed based on the findings of a series of preliminary studies targeting to determine the characteristics and needs of the target groups, and identify the barriers to engage in physical activity. Two quasi-experimental studies were conducted with 309 university students from the two countries (200 participants from Turkey and 109 participants from the UK) to test the effects of framed messages on intentions and attitudes towards physical activity, and physical activity behaviour change in two weeks after message exposure. Results showed that immediate effects of both gain- and loss-framed messages on physical activity intentions and attitudes were significant in Turkey and the UK. However, these effects could not be maintained in the two weeks following the message exposure. Moreover, the loss-framed message led to a message reactance in the UK, and physical activity intensity of the participants in the loss-framed group were significantly decreased compared to their baseline physical activity levels. The present study was the first message framing study comparing Turkey and the UK in terms of the impact of gain- and loss-framed framed physical activity messages. Therefore, this study contributes to the literature through providing evidence on the effects of message framing interventions which are developed and implemented in different cultures. Recommendations for future message framing research include measuring physical activity behaviour through objective methods, and examining the impact of the tailored messages through using different dissemination methods in larger samples. |
