Personality,motivational, and social cognition predictors of leisure-time physical activity

ObjectiveThe purpose of the present study was to investigate associations between personality traits of extraversion and neuroticism, autonomous motivation, and the Theory of Planned Behavior (TPB) constructs and leisure-time physical activity. The study examined whether autonomous motivation and the TPB constructs mediate the association between personality traits and physical activity, and whether personality traits moderate the relationship of autonomous motivation and the TPB constructs with physical activity.MethodsMiddle-aged women (N = 441) completed self-report measures of personality traits, autonomous motivation, attitudes, subjective norms, perceived behavioral control (PBC) and intention. Moderate-to-vigorous leisure-time physical activity (MVPA) was measured using accelerometers approximately seven weeks later. Participants’ past accelerometer-based MVPA was available from four years earlier.ResultsOnly autonomous motivation and past MVPA directly predicted MVPA. Neuroticism and past MVPA were indirectly related with MVPA through autonomous motivation. No support for a moderator role of personality traits was found.ConclusionsCurrent data suggest that autonomous motivation and past experience are prominent determinants of accelerometer-based leisure-time MVPA, but not beliefs and intentions.     

Motivation is not enough: prediction of risk behavior following diagnosis of coronary heart disease from the theory of planned behavior.

Perceived behavioral control (PBC) and intention, the proximal predictors from the theory of planned behavior (TPB), were used to predict cardiovascular risk behaviors in 597 patients 1 year after diagnosis with coronary heart disease. The outcome measures were self-report measures of exercise plus objective measures of fitness (distance walked in 6 min) and cotinine-confirmed smoking cessation. In multivariate analyses incorporating both PBC and intention, PBC predicted exercise, distance walked, and smoking cessation, but intention was not a reliable independent predictor of any health behavior measured. Thus, the effective theoretical component of the TPB was PBC. Similar predictions could derive from social-cognitive theory. In coronary patients, behavioral change needs to address issues of action implementation rather than motivational factors alone.     

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.     

Antecedents of children's physical activity intentions and behaviour: Predictive validity and longitudinal effects

Abstract

This study examined the predictive validity and time-lagged relationships in a model of children's physical activity intentions, attitudes, perceived behavioural control (PBC), behaviour and past behaviour using the Theory of Planned Behaviour (TPB; Ajzen, 1985) as a framework. In Study 1, 386 children aged 12–14 years completed measures of intentions, attitudes, subjective norm, PBC and past behaviour. Their physical activity behaviour was assessed one week later. Structural equation analyses supported the construct and predictive validity of the TPB with the exception of subjective norms which did not predict intentions. In Study 2,70 children completed measures of their physical activity attitudes, intentions, PBC and past behaviour. Attitudes, intentions, PBC and recent behaviour were re-assessed five weeks later. The cognitions demonstrated a moderate degree of stability over time and there were some cross-lagged effects between attitudes and PBC. Past behaviour demonstrated additive rather than attenuating effects. These results support the use of the TPB cognitions and past behaviour as a framework to examine children's physical activity behaviour.     

Assessing the feasibility of the theory of planned behaviour in predicting drivers’ intentions to operate conditional and full automated vehicles

Guided by the Theory of Planned Behaviour (TPB), this study examined the beliefs underpinning, and feasibility of the factors in predicting, individuals’ intentions to use a conditional (Level 3) automated vehicle (AV) and a full (Level 5) AV. Australian drivers (N = 505) aged 17–81 years (Mean age = 33.69, SD = 18.79) were recruited and completed a 20 min online survey which featured both quantitative and qualitative items. For the quantitative data, two linear regressions revealed that the TPB standard constructs of attitudes, subjective norm, and perceived behavioural control (PBC) accounted for 66% of the variance in intentions to use a conditional AV and 68% of the variance in intentions to use a full AV. Of the TPB constructs, attitudes and subjective norms were significant positive predictors of future intentions to use conditional and full AVs. For the qualitative data, some differences emerged for the underlying behavioural beliefs that underpinned intentions to use conditional and full AVs. For example, having beliefs about control over the conditional AV was identified by many participants as an advantage, while not being in full control of the full AV was identified as a disadvantage. For underlying control beliefs, participants identified similar barriers for both vehicle types, including; high costs, lack of trust, lack of control over the vehicle, lack of current legislation to support the mainstream introduction of these vehicles, and concerns of safety for self and for other road users when operating AVs. Overall, these findings provide some support for applying the TPB to understand drivers’ intended use of AVs. However, while the current study showed that the constructs of attitudes and subjective norms might reflect intended use of AVs, more research is required to further examine the role of PBC. Additionally, the findings provide initial insights into the underlying behavioural and control beliefs that may motivate drivers to use AVs and highlight the similarities and differences in drivers’ perceptions towards two levels of vehicle automation.     

To Be a Donor or Not to Be? Applying an Extended Theory of Planned Behavior to Predict Posthumous Organ Donation Intentions

Using a theory of planned behavior (TPB) perspective, individual intentions to register and discuss the decision of organ donation with significant others were examined. In addition to standard TPB variables (attitude, subjective norm, and perceived behavioral control [PBC]), self-identity and moral norm were incorporated into the TPB as predictors. Australian university students ( N  = 303) completed a survey comprising standard and additional TPB constructs. Separate analyses were conducted for both registered and nonregistered participants. In general, results provide support for the extended TPB model in predicting intentions to register and discuss the donation decision, with the exceptions that self-identity did not predict discussion intentions for either registered or nonregistered participants, and PBC did not predict discussion intentions for nonregistered participants.     

Attitude,perceived behavioral control,and intention to adopt risky behaviors

The theory of planned behavior (TPB, Ajzen, 1985) has proved its efficiency in predicting different behaviors among road users (Sheeran & Orbell, 2000). The present study examined the TPB factors explaining risk taking among vulnerable road users (e.g., cyclists). We presumed that attitude, social norms, and perceived behavioral control (PBC) would predict cyclists’ intention to adopt a risky behavior in two traffic contexts considered as risk-conducive (i.e., run the red-light, turn left).Participants (N = 224, M_age = 23.34) filled in an online scenario-based questionnaire describing two traffic situations conducive to risk taking and including measures for cyclists’ intentions to adopt risky behaviors in these specific contexts, TPB factors, and self-perceived efficacy.TPB factors explained 49% and 65% of the variance in the intention to cross the red light, respectively the intention to turn left, with positive attitude and high PBC as the best predictors. Implications of the results were discussed.     

Development and test of an integrative model of job search behaviour

Research on job search and the theory of planned behaviour (TPB) has identified job search attitude, subjective norm, and job search self-efficacy as the most proximal determinants of job seekers’ search intentions and subsequently job search behaviours. However, we do not yet know how more distal individual differences (e.g., personality) and situational factors (e.g., social context) might help to predict these key TPB determinants of job search behaviour. In an integrative model of job search behaviour, we propose specific relationships between these distal variables and the TPB determinants, which in turn are expected to mediate the effects of individual differences and situational factors on job search behaviour. The hypothesized model is tested in a large representative sample of 1,177 unemployed Flemish job seekers using a two-wave design and provides a satisfactory fit to the data. Extraversion, conscientiousness, core self-evaluations, employment commitment, financial need, and social support are found to differentially relate to instrumental job search attitude, affective job search attitude, subjective norm, and job search self-efficacy. In addition, all distal variables are indirectly related to job search behaviour through their effects on the TPB variables. These results support our expanded and integrative model of job search behaviour.     

To share or not to share: A theoretically guided investigation of factors predicting intentions to use fully automated shared passenger shuttles

This study applied the Theory of Planned Behaviour (TPB) to assess individuals’ intentions to use fully automated shared passenger shuttles when they become publicly available. In addition, perceived trust was assessed to examine the extent to which this variable could account for additional variance in intentions above the TPB constructs of attitudes, subjective norms, and perceived behavioural control (PBC). Further, and also guided by the TPB, the study explored the differences in behavioural, normative, and control beliefs between individuals who reported high intentions to use automated passenger shuttles in the future (high intenders) and individuals who reported low intentions to use fully automated shared passenger shuttles in the future (low intenders). Participants (N = 438; 64% female) aged between 17 and 84 years (Mage = 35.42 years) were asked to complete an online questionnaire which took approximately 15 min. The findings revealed that attitudes, subjective norms, and PBC were significant positive predictors of intentions to use fully automated shared passenger shuttles when they become publicly available. When perceived trust was added to the hierarchical regression, this variable was shown to account for additional significant variance in intentions above the TPB constructs and was shown to be a significant positive predictor of intentions. Further, the results revealed significant differences in beliefs held by high and low intenders. Specifically, high intenders held significantly more positive beliefs towards fully automated shared passenger shuttles than low intenders. In turn, low intenders held significantly more negative beliefs towards these vehicles than high intenders. Overall, these findings provide support for the utility of the TPB in examining individuals’ intentions to use fully automated shared passenger shuttles when they become publicly available.     

Personality,interview faking,and the mediating role of attitudes,norms, and perceived behavioral control

This study investigated the psychological processes underlying interview faking, and that link personality to interview faking. In a sample of 198 recent interviewees, surveyed across three time points, we examined the mediating role of three constructs from the theory of planned behavior (TPB; i.e., attitudes, subjective norms, and perceived behavioral control) in explaining the relationship between the traits of Honesty–Humility and Conscientiousness and one form of interview faking (i.e., extensive image creation). Results indicated that all three TPB constructs correlated with interview faking, although only attitudes and subjective norms predicted faking incrementally. Attitudes and norms mediated the relationships between Honesty–Humility and Conscientiousness and interview faking. This study provides insight into interview faking, and the link between personality and interview faking.     

Having Casual Sex: Additive and Interactive Effects of Alcohol and Condom Availability on the Determinants of Intentions

The impact of alcohol, condom availability, and gender on intentions to engage in casual sex and its antecedents was investigated. Students ( N = 384) who were or were not intoxicated with alcohol completed measures based on the theory of planned behavior (TPB) in relation to having casual sex in a scenario. The scenario described sex between 2 individuals not in a relationship and manipulated the consumption of alcohol of the sexual partners and availability of condoms. The data were supportive of the TPB: Intentions were predictable from attitudes, subjective norms, and perceived behavioral control (PBC). Results also support the inclusion of measures of past behavior and anticipated affective reactions, but not self-identity or moral norms as predictors of intentions. Alcohol in the scenario and condom availability increased intentions to have sex. There were also several interaction effects. Implications for using the TPB to understand sexual behaviors under the influence of alcohol are discussed.     

The role of self-efficacy in predicting rule-following behaviors in shelters for homeless youth: a test of the theory of planned behavior

Through a prospective study of 70 youths staying at homeless-youth shelters, the authors tested the utility of I. Ajzen's (1991) theory of planned behavior (TPB), by comparing the constructs of self-efficacy with perceived behavioral control (PBC), in predicting people's rule-following behavior during shelter stays. They performed the 1st wave of data collection through a questionnaire assessing the standard TPB components of attitudes, subjective norms, PBC, and behavioral intentions in relation to following the set rules at youth shelters. Further, they distinguished between items assessing PBC (or perceived control) and those reflecting self-efficacy (or perceived difficulty). At the completion of each youth's stay at the shelter, shelter staff rated the rule adherence for that participant. Regression analyses revealed some support for the TPB in that subjective norm was a significant predictor of intentions. However, self-efficacy emerged as the strongest predictor of intentions and was the only significant predictor of rule-following behavior. Thus, the results of the present study indicate the possibility that self-efficacy is integral to predicting rule adherence within this context and reaffirm the importance of incorporating notions of people's perceived ease or difficulty in performing actions in models of attitude-behavior prediction.     

Regulatory focus and work-related outcomes: A review and meta-analysis

Regulatory focus theory (Higgins, 1997) has received growing attention in organizational psychology, necessitating a quantitative review that synthesizes its effects on important criteria. In addition, there is need for theoretical integration of regulatory focus theory with personality research. Theoretical integration is particularly relevant, since personality traits and dispositions are distal factors that are unlikely to have direct effects on work behaviors, yet they may have indirect effects via regulatory focus. The current meta-analysis introduces an integrative framework in which the effects of personality on work behaviors are best understood when considered in conjunction with more proximal motivational processes such as regulatory focus. Using a distal-proximal approach, we identify personality antecedents and work-related consequences of regulatory foci in a framework that considers both general and work-specific regulatory foci as proximal motivational processes. We present meta-analytic results for relations of regulatory focus with its antecedents (approach and avoid temperaments, conscientiousness, openness to experience, agreeableness, self-esteem, and self-efficacy) and its consequences (work behaviors and attitudes). In addition to estimates of bivariate relationships, we support a meta-analytic path model in which distal personality traits relate to work behaviors via the mediating effects of general and work-specific regulatory focus. Results from tests of incremental and relative validity indicated that regulatory foci predict unique variance in work behaviors after controlling for established personality, motivation, and attitudinal predictors. Consistent with regulatory focus theory and our integrative theoretical framework, regulatory focus has meaningful relations with work outcomes and is not redundant with other individual difference variables.

Alcohol Consumption and the Theory of Planned Behavior: An Examination of the Cognitive Mediation of Past Behaviorid

This study examined the predictive power of the theory of planned behavior (TPB) in explaining alcohol consumption in 3 prospective samples of students ( Ns = 178. 176. and 159). Generally, the TPB performed well. with attitudes, subjective norms and perceived behavioral control (PBC) explaining between 28% and 46% of the variability in intentions. Intentions and PBC explained between 12% and 50% of the variability in behavior. Measures of self-identity as a "drinker" and past behavior contributed to predictions of intentions over and above the contribution of attitudes. subjective norms. and PBC. Measures of past behavior but not self-identity consistently contributed to predictions of behavior over and above the contributions from intentions and PBC. The direct relationship between past behavior and intention and between past behavior and behavior (independent of the TPB variables or self-identity) could not be attributed to common method variance.     

A Test of Self-Determination Theory in the Exercise Domain

In accordance with self-determination theory (SDT; Deci & Ryan, 1985 ), this study examined the relationship between autonomy support, psychological need satisfaction, motivational regulations, and exercise behavior. Participants ( N =369) were recruited from fitness, community, and retail settings. Fulfillment of the 3 basic psychological needs (i.e., competence, autonomy, and relatedness) related to more self-determined motivational regulations. Identified and introjected regulations emerged as positive predictors of strenuous and total exercise behaviors. Competence need satisfaction also predicted directly—and indirectly via identified regulation—strenuous exercise. For participants engaged in organized fitness classes, perceptions of autonomy support provided by exercise class leaders predicted psychological need satisfaction. Furthermore, competence need satisfaction partially mediated the relationship between autonomy support and intrinsic motivation. These findings support SDT in the exercise domain.     

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.     

Using national survey data incorporating the theory of planned behavior: Implications for social marketing strategies in physical activity

Abstract

This paper illustratesthe potential use of the Theory of Planned Behavior (TPB) as a guiding fiamework for the conduct of population based survey research to develop strategies to promote physical activity involvement in various market segments. The Campbell's Survey of Well-Being (1988), a nation-Wide representative study of the Canadian population incorporated a modified operationali- zation of the TPB Pertainingto intended involvement in regularphysical activity. The theory was found to be generally effitive in munting for intentions in the general population (Rz= .32)as well as in various age and gender subgroups. Whereas, neither the model's direct predictors of intentions (e.g., attitudes, sub jective normdsocial support, perceived behavioral control) nor the indirect predictors (e.g., the beliefs underlying these predictors) varied consistently across gender, a number of age-related differenceswere observed. These differencesare used to exemplify how population-based data utilizing the TPB can be utilized to develop promotional and programming implications for fostering greater physical activity involvement in various ag-ender market segments.     

Social-cognitive predictors of intention to vaccinate against the human papillomavirus in college-age women

This study examined social-cognitive predictors of college-age women's intentions to obtain the human papillomavirus (HPV) vaccine using the Health Belief Model (HBM) and Theory of Planned Behavior (TBP) as theoretical guides. Questionnaire data were collected from 143 women at a Midwestern university. Among the HBM variables, perceived susceptibility to HPV, perceived benefits of the vaccine, and self-efficacy to obtain the vaccine were significant predictors. Among the TPB variables, positive attitudes toward the vaccine and beliefs that important others would support vaccination predicted intentions. A model with all HBM and TPB variables explained nearly 60% of the variance in intentions. Comparison of the theories suggests that the TPB is a better predictor of intentions than the HBM. Results suggest that targeting personal beliefs about the vaccine, and increasing acceptance for the vaccine among social network members, may increase vaccination intentions among college-age women.
