The effects of persuasive communication and planning on intentions to be more physically active and on physical activity behaviour among low-active adolescents

Abstract

The purpose of the present study was to examine, using the theory of planned behaviour (TPB) combined with a self-regulatory behaviour change approach, whether persuasive communication based on adolescents' salient beliefs (SBCondition) and planning (PCondition) could promote the intention and physical activity (PA) behaviour of low-active adolescents participating in less than 1 h/day of moderate-to-vigorous physical activity. The protocol tested the effectiveness of two strategies used separately (i.e. SBC or PC) or in combination (i.e. CC = NSBC-SBC-PC) compared to a group receiving a message based on non-salient beliefs (NSBCondition). The 116 low-active students from ten 10th and 11th grade classes were assigned, using a cluster randomisation, into one of the four conditions (i.e. NSBC, SBC, PC and CC). Baseline data were collected two weeks before the intervention. The post-test data collection occurred directly after the intervention, and the follow-up took place two weeks later. Results showed that (1) the NSBC was the least effective strategy, (2) the SBC had no significant effect on PA behaviour and the TPB variables, (3) the PC had no significant effect on PA behaviour but increased the intention and perceived behavioural control and (4) the effects of the PC and the CC were not significantly different.

What Influences Chinese Adolescents’ Choice Intention between Playing Online Games and Learning? Application of Theory of Planned Behavior with Subjective Norm Manipulated as Peer Support and Parental Monitoring

“…The present study investigated how and why Chinese adolescents choose between playing online games and completing learning tasks when playing online games would use up learning time, using TPB as theoretical framework, which has been widely used to predict adolescents’ behavior and intention (e.g., Baker and White, 2010; Christiana et al, 2014; Walrave et al, 2014; Tessier et al, 2015). Specifically, the predictive roles of attitude, PBC, and subjective norm in adolescents’ decision making regarding online games, as outlined by TPB, were investigated in this study, wherein a conflict between playing online games and doing homework was introduced.…”

DEBATE: Do interventions based on behavioral theory work in the real world?

“…A substantive body of research has identified the effectiveness of theory-based interventions targeting change in modifiable determinants or mechanisms [22–24]. For example, syntheses of evidence have indicated that interventions targeting change in social cognitive beliefs and motivation [25–31], social support and norms [32, 33], and planning [29] to be effective in promoting behavior change in randomized controlled trials. Similarly, interventions based on health-risk communications have been successful in promoting behavior change [34], with graphic images on tobacco products a prominent example [35–38].…”

Construção e validação de recursos audiovisuais para motivar pessoas com hipertensão ao uso de anti-hipertensivos

“…Audiovisual communication and persuasive messages produced in an attractive way, using the resources of images and sound with persuasive language, are considered stimulating tools with the potential to influence the adoption of health behaviors. 7,8,14 Information-only interventions for the management of hypertension have limited effectiveness, particularly among disadvantaged populations. 24 In the face of such findings, the use of videos only with information about the disease, as well as informative written messages, is not sufficient.…”

“…5 Messages with different frameworks (positive or negative) can be included in order to influence beliefs, attitudes, subjective norms and perceived control and, consequently, the conception of an intention favorable to the realization of the behavior. 4 The application of persuasive messages and/or communications to health-related behaviors has shown incentive and maintenance of preventive behaviors, [7][8][9] influence in the displacement of beliefs 10,11 and variation in behavioral intention. 12,13 In the cardiovascular diseases scenario, studies were found that developed persuasive messages to promote physical activity, 14 and obtaining adherence to therapeutic and preventive recommendations among individuals with coronary artery disease.…”
