Prediction of Behaviour vs. Prediction of Behaviour Change: The Role of Motivational Moderators in the Theory of Planned Behaviour

Research has identified moderating variables of the cognition–behaviour relationship in the Theory of Planned Behaviour (TPB). These include intention certainty, affective–cognitive congruence of attitudes, attitudinal ambivalence, and past behaviour. It has not yet been systematically tested if these moderators apply in similar ways to the prediction of behaviour and behaviour change (when past behaviour is controlled). A sample of 1,418 university students completed measures of the direct predictors of the TPB (perceived behavioural control; PBC and intention), intention certainty, affective–cognitive congruence of attitudes, attitudinal ambivalence, and the Godin Leisure Time Physical Exercise Questionnaire at the beginning of the academic year and two months later. Data were analysed using moderated hierarchical linear regressions. Without controlling for baseline behaviour, intention certainty and affective–cognitive congruence moderated both the intention–behaviour and PBC–behaviour relationships and showed additional main effects. Attitudinal ambivalence did not contribute to the prediction. When past behaviour was controlled, the main effects were attenuated and only the intention certainty* PBC interaction remained significant. Predictors of behaviour do not necessarily predict behaviour change. The TPB-related moderators studied here weakly contributed to the prediction of behaviour change. Proposals for increasing the predictive power of TPB for behaviour change are discussed.     

The Effects of Social Identity and Perceived Autonomy Support on Health Behaviour Within the Theory of Planned Behaviour

The present study employed constructs from self-determination theory, social-identity theory, and the theory of planned behaviour to examine the combined effects that social identity and perceived autonomy support exerted on attitudes, intentions and health behaviour. A prospective design was employed measuring constructs from the theory of planned behaviour, group norms, group identification, and perceived autonomy support at baseline and physical activity behaviour 5 weeks later. Self-report questionnaires were administered to 231 pupils (male = 113, female = 118, M = 14.21 years, SD = .90). Hierarchical regression analysis demonstrated that group norms predicted participation in physical activities and attitudes, but only for participants who identified strongly with their group. Perceived autonomy support predicted attitudes, intentions and behaviour. The effects of perceived autonomy support and social-identity constructs were independent. It was concluded that both social identity and perceived autonomy support should be included in the theory of planned behaviour.     

Application of the Theory of Planned Behaviour in Behaviour Change Interventions: A Systematic Review

This paper reviews studies explicitly applying the Theory of Planned Behaviour (TPB) to behaviour change interventions. A systematic and multiple search strategy identified 30 papers, describing 24 distinct interventions. Studies were rarely explicit about use of the TPB. The TPB was mainly used to measure process and outcome variables and to predict intention and behaviour, and less commonly to develop the intervention. Behaviour change methods were mostly persuasion and information, with increasing skills, goal setting, and rehearsal of skills used less often. When reported, half of the interventions were effective in changing intention, and two-thirds in changing behaviour, with generally small effect sizes, where calculable. Effectiveness was unrelated to use of the theory to develop interventions. Evidence about mediation of effects by TPB components was sparse. The TPB may have potential for developing behaviour change interventions, but more comprehensive studies are needed that compare the utility of the TPB with other social cognition models and behavioural techniques.     

Accounting for the Theory of Planned Behaviour in departure time choice

Motivating people to change their departure time could play a key role in reducing peak-hour congestion, which remains one of the most prevalent transport problems in large urban areas. To achieve this behavioural change, it is necessary to better understand the factors that influence departure time choice. So far departure time choice modelling focussed mainly on objective factors, such as time and costs as main behavioural determinants. In this study, we derived psychological factors based on the Theory of Planned Behaviour, estimated them based on structural equation modelling, and included them into a discrete choice model. The psychological factors were measured based on an online questionnaire addressed to car commuters to the city centre of Copenhagen (N = 286). The questionnaire additionally included a travel diary and a stated preference experiment with nine departure time choice scenarios. All psychological factors had a significant effect on departure time choice and could improve the model as compared to a basic discrete choice model without latent constructs. As expected, the effects of the psychological factors were different depending on framework conditions: for people with fixed starting times at work, the intention to arrive at work on time (as estimated by subjective norm, attitude, perceived behavioural control) had the strongest effect; for people with flexible working hours, the attitude towards short travel time was most relevant. Limitations, the inclusion of additional psychological factors and their possible interactions are discussed.     

The influence of Sociocultural Paradigms

This research examined the influence of sociocultural paradigms of menopause on attitudes toward menopause. Five hundred eighty-one women and men, between the ages of 18 and 85, were assigned to one of three groups distinguished by the context within which they expressed their attitudes toward menopause. The contexts were designed to reflect particular paradigms: one group described their attitudes toward three medical problems, including menopause; a second group described their attitudes toward three life transitions, including menopause; and a third group described their attitudes toward three symbols of aging, including menopause. Positive and negative subscales of the attitude questionnaires for menopause were analyzed for context and age/experience. Results indicated that the medical context elicited significantly more negative and fewer positive attitudes than did the other two contexts, particularly among older participants. In general, women's attitudes were more positive than were men's, and attitudes became increasingly positive with age and/or experience. The discussion includes the potential role of attitudes as mediating the impact of sociocultural paradigms on experience and behavior.     

Theory of Planned Behaviour, Skin Care and Pressure Sores Following Spinal Cord Injury

Objectives: To use the Theory of Planned Behaviour to explore factors associated with performing skin care behaviors and the occurrence of pressure sores in people with spinal cord injury. Design: A within-group cross-sectional design was used to assess 59 people with spinal cord injury living in the community. Of these, 17 participants returned a repeat assessment allowing a longitudinal examination of the relationship between intention and actual behaviour. Methods: A measure was developed in accordance with the Theory of Planned Behaviour guidelines through interviews with people with spinal cord injury. Measures of mood and knowledge of skin care behaviour were also included. Results: The Theory of Planned Behaviour components, mood and knowledge of skin behaviours predicted intention, skin care behaviour and occurrence of pressure sores. Knowledge of skin care was negatively correlated with occurrence of pressure sores (r=−.38, p < .01). Indirect perceived control was a particularly important predictor of pressure relief, accounting for 24% of the variance. Conclusions: Psychosocial factors, including the Theory of Planned Behaviour components, predicted skin care behaviours and the occurrence of pressure sores. These findings provide empirical support for the Theory of Planned Behaviour. The study also carries clinical implications for skin care education for people with SCI and their families.     

Analysing the Influence of Autonomous and Controlling Social Factors Within the Theory of Planned Behaviour

The aim of this study was to analyse the effects of autonomous (i.e., autonomy support from parents and peers) and controlling (i.e., social physique anxiety) social factors on future intention to exercise, integrating the distal (i.e., basic psychological needs satisfaction and self‐determined motivation) and proximal (i.e., attitudes, perceived behavioural control and subjective norms) determinants of intention defined in self‐determination theory (SDT) and the theory of planned behaviour (TPB). Self‐report questionnaires were distributed to 390 secondary school pupils (male = 218, female = 172, M_age = 15.10, standard deviation = 1.94). The results of path analysis, controlling for past behaviour of physical activity, showed that social factors predicted future intention to exercise through the influence of the distal and proximal determinants. The main contribution of the study was to provide evidence that the proximal determinants of the TPB captured the direct influence of social factors, independent of the mediating effects of psychological needs satisfaction and self‐determined motivation towards exercise. Results supported the integration of the two theories, clarifying the processes of influence of autonomous and controlling social factors within the variables of SDT and the TPB.     

Adherence to Hormone Replacement Therapy: A Longitudinal Study Using the Theory of Planned Behaviour

The aim of this longitudinal study was to assess the stability and determinants of the intention to adopt HRT over a one-year period using the Theory of Planned Behaviour. At baseline, a total of 644 middle-aged premenopausal women who had never used HRT, were recruited. At follow-up, 417 women completed an interview to assess any change in their reproductive status and in their behavioural intention. Among women who stayed premenopausal (n = 172) and among those who became perimenopausal (n = 209), the intention to adopt HRT was quite stable over the one-year period. However, being perimenopausal had a significant effect on the intention to adopt HRT at follow-up, as did subjective norm, perceived behavioural control and moral norm measured at baseline. Attitude towards HRT did not have a significant effect on the intention to adopt HRT one year later. Therefore, interventions to support women's decision-making about HRT should be tailored to their menopausal status and take into account their perception of social pressure to perform, control over this behaviour and moral obligation.     

Binge-Drinking: A Test of the Role of Group Norms in the Theory of Planned Behaviour

A study was undertaken to assess the utility of the theory of planned behaviour in the prediction of students' binge-drinking. Additionally, a perspective was utilised to address the usually weak contribution of subjective norms in predicting behavioural intentions. Respondents were 289 undergraduate students. The study employed a longitudinal design, with the predictors of performing the behaviour under consideration assessed prior to the measure of reported behaviour. Support was found for the application of the theory of planned behaviour to binge-drinking. A reconceptualisation of norms in the theory of planned behaviour, from a social identity theory/self-categorization theory perspective, was also supported; consistent with expectations, the norms of a behaviourally relevant reference group predicted intentions to binge-drink, especially for participants who identified strongly with the reference group. The results are discussed in relation to measures which may help to reduce the incidence of binge-drinking by university students.     

Exploring Academic Dishonesty among University Students in Barbados: An Extension to the Theory of Planned Behaviour

This paper applies Beck and Ajzen’s (Journal of Research in Personality 25:285–301, 1991) extended version of the theory of planned behaviour model to the decisions of students to engage in academic dishonesty (cheating and lying). The model proposes that students’ intentions to engage in dysfunctional behaviours may be influenced by attitudes, subjective norms, perceived behavioural control and moral obligation. This study was done using a survey questionnaire of 363 undergraduate students at a West Indian University. Based on the extended version of the theory of planned behaviour, with the exception of subjective norms which only predicted students’ intentions to cheat, it was found that attitudes, perceived behavioural control and moral obligation were significant predictors of students’ intentions to perform academic dishonesty behaviours in the form of cheating and lying. The results of the study have given further support to the use of the extended version of the theory of planned behaviour. Implications are discussed.     

A Configurational Perspective on the Theory of Planned Behaviour to Understand Employees' Change‐Supportive Intentions

This study aims to deepen the understanding of the psychological processes involved in the formation of change‐supportive intentions by adopting a configurational perspective. To investigate potential configurations in relevant psychological processes suggested by the theory of planned behaviour (Ajzen, 1991 ), classical linear analytic methods are supplemented by the application of two case‐centred methods: latent profile analysis (LPA) and fuzzy set qualitative comparative analysis (fsQCA). The study uses data from two measurement times drawing on employees of a city council (t1: N = 1,589; t2: N = 1,524) undergoing complex and continuous organisational changes. While the case‐centred results from LPA and fsQCA generally accord well with the results from regression analysis, they consistently highlight the relevance of configurational patterns. Specifically, LPA and fsQCA reveal that different combinations of change‐related attitudes, subjective norms, and perceived behavioural control relate to the presence or absence of high supportive intentions. These results provide valuable insights for fostering employees' change‐supportive intentions. Moreover, the present study demonstrates that case‐centred analytical methods can essentially enrich research and theory‐building in change management as well as in the field of behavioural intention formation in general.     

Using the Theory of Planned Behaviour and implementation intentions to predict and facilitate upward family communication about mammography

Regular mammography facilitates early detection of breast cancer, and thus increases the chances of survival from this disease. Daughter-initiated (i.e. upward) communication about mammography within mother-daughter dyads may promote mammography to women of screening age. The current study examined this communication behaviour within the context of the Theory of Planned Behaviour (TPB), and aimed to bridge the intention-behaviour gap by trialling an implementation intention (II) intervention that aimed to facilitate upward family communication about mammography. Young women aged 18-39 (N=116) were assigned to either a control or experimental condition, and the latter group formed IIs about initiating a conversation with an older female family member about mammography. Overall, those who formed IIs were more likely to engage in the target communication behaviour, however the intervention was most effective for those who reported low levels of intention at baseline. Perceived behavioural control emerged as the most important variable in predicting the target behaviour. The altruistic nature of this behaviour, and the fact that it is not wholly under volitional control, may have contributed to this finding. Future studies that systematically explore the relative roles of intention and perceived behavioural control in behaviours of this nature are warranted.     

Supportive Social Contexts and Intentions for Civic and Political Participation: An Application of the Theory of Planned Behaviour

We investigated how general social support from family, friends and acquaintances, and community predicted intentions for civic (e.g. volunteering) and political (e.g. petitioning) participation via the constructs specified in the theory of planned behaviour. Participants were young adults living in the former East Germany, a post‐communist region, who were surveyed by telephone in 2010 (N_civic = 695, N_political = 694). Civic participation was perceived more favourably than political participation. Supportive family predicted intentions for civic participation; supportive community services predicted both types of intentions; and supportive friends and acquaintances had no significant effects. The mediating variables were subjective norms and perceived behavioural control, but not attitudes. All effects were controlled for sociodemographic variables, richness of the social network, and past experience of civic and political participation. Findings underscore the role of supportive community in fostering both civic and political participation. Copyright © 2014 John Wiley & Sons, Ltd.     

Mediating relationship between body mass index and the direct measures of the Theory of Planned Behaviour on physical activity intention

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.

Prospective Study on the Determinants of Repeat Attendance and Attendance Patterns in Breast Cancer Screening Using the Theory of Planned Behaviour

This prospective study, using the Theory of Planned Behaviour (TPB) as a theoretical framework, was carried out to identify the determinants of repeat attendance and attendance patterns in organised breast screening. A group of 2657 women filled out a baseline questionnaire, approximately 8 weeks after having been invited for an initial screening in the Dutch Breast Cancer Screening Programme. Data on actual attendance in second and third screening round were subsequently collected. Personal variables such as family history of breast cancer, breast cancer in someone close and fear of breast cancer were not related to repeat attendance. The TPB variables could explain approximately 17% of the variance in attendance in the second and third round. Maintenance behaviour (consistent attendance vs. dropout) was related to the TPB variables, but the amount of variance explained was only 6%. Initiation of behaviour (consistent refusal vs. delayed attendance) also was related to TPB variables, with a substantially higher amount of explained variance than with maintenance behaviour. Results indicate that the TPB variables are more related to the initiation of screening behaviour than to the maintenance of screening behaviour. Implications of these findings for breast cancer screening are discussed.
