THE RELATION BETWEEN BEHAVIORAL INTENTIONS AND BELIEFS: A PROBABILISTIC MODEL1

Based on mathematical probability theory, a model of the relationship between beliefs and behavioral intention was proposed and tested. In Experiment 1, subjects indicated their beliefs about the consequences of smoking cigarettes as well as their intention to smoke cigarettes. When combined according to the proposed model the average correlation between predicted and obtained behavioral intention was .78 (p<.01). In Experiment 2, implications of the model for changing behavioral intentions were examined. Subjects were presented a hypothetical election campaign between two candidates. Intentions to vote for a given candidate were measured prior to and after presentation of information about some of the candidates' political views. Using the proposed model of intention, the predicted and observed changes in voting intentions were correlated .72 (p<.01). Implications of the model for theories of social behavior and persuasion were discussed.     

Negative Beliefs as a Moderator of the Intention–Behavior Relationship: Decisions to Use Performance-Enhancing Substances

The theory of reasoned action framework was used to examine performance-enhancing substance use among a sample of college athletes in a prospective longitudinal design. Results indicate that attitudes and subjective norms predicted intention to use the substances, and these intentions predicted actual substance use 6 weeks later. A statistically significant interaction emerged between negative beliefs and intentions predicting behavior such that as negative beliefs grew increasingly negative, the intention–behavior relationship became stronger. Practical and theoretical implications of the influence of negative information on the intention–behavior relationship are discussed.     

Second-order beliefs about intention and children's attributions of sociomoral judgment

Predicting how another person will evaluate the intention underlying an action involves consideration of second-order mental states. Children (ages 5-10 years) and college students (N=105) predicted an observer's belief about an actor's intention and evaluated the actor from both their own perspectives and the perspective of the observer. Younger children were more likely than older children and adults to attribute a belief to the observer that mismatched the actor's prior intention. Attributed beliefs about intention were more likely to match negative prior intentions than to match positive prior intentions and were also more likely to match prior intentions when the observer knew the actor's prior intention than when the observer did not know the actor's prior intention. The judgments attributed to the observer were based on the beliefs about intention attributed to the observer, showing use of second-order mental states to infer another's sociomoral judgments.     

The prediction of safe sex behaviour: The role of intentions,attitudes, norms and control beliefs

Abstract

The present study was designed to examine the utility of the theory of reasoned action (Fishbein and Azjen, 1975) in relation to people's propensity to engage in a range of different safe sex strategies, including engaging in an exclusive sexual relationship, avoiding casual sex, and asking sexual partners about their previous sexual and IV drug use history. It was proposed that the intention to engage in a particular safe sex practice would be influenced by the person's attitude towards engaging in the practice, as well as his or her perception of the extent to which others thought they should do so (subjective norm), while behavioural intentions were proposed to predict actual behaviour. The study was also designed to examine whether, after control of the effects of the components of the theory of reasoned action, the person's generalised control beliefs would explain any additional variance in either behavioural intentions or actual behaviour. One hundred and two sexually active heterosexual students participated in the study. At the first wave of data collection, subjects completed measures of intentions, attitudes, and norms appropriate to each of the different behaviours. Measures of actual behaviour were obtained at follow-tip (three months after first period of data collection). The results of the study indicated that attitudes and norms predicted intentions for avoiding casual sex and asking sexual partners about their previous sexual and IV drug use history, while intentions predicted actual behaviour for all three safe sex strategies. Although there were no significant main effects of control beliefs on intentions or behaviour, subjects with internal control beliefs were more likely than their counterparts with external control beliefs to behave in accordance with their intentions to engage in an exclusive sexual relationship and ask sexual partners about their previous sexual and IV drug use history. Additional analyses revealed that the levels and determinants of intentions and actual behaviour were, in general, similar for males and females.     

To Have–or Not to Have–Another Child: Family Planning Attitudes,Intentions, and Behavior1

Two hundred eighty-two respondents, representing 141 married couples with either one child (N= 71 couples) or two children (N= 70 couples), were interviewed about their considerations and intentions regarding whether or not to have another child. Reports of their actual subsequent family planning behavior were obtained 12 months later via a mailed questionnaire. The data was gathered and analyzed according to Fishbein's attitude-behavior model which stipulates that the individual's actual behavior is a function of one's behavioral intention. This intention, in turn, is determined by two multiple factors: (a) the individual's beliefs about the consequences of performing the behavior multiplied by his/her evaluation of those consequences, and (b) one's normative beliefs multiplied by one's motivation to comply with the perceived norms. The results provided substantial support for the model; both behavioral intention and actual behavior were successfully predicted from the attitudinal and normative components of the model. It was also shown that the behavioral intention mediates the relationship between the model's attitudinal and normative components and actual behavior.     

Cultural predictors of future intention to drive under the influence of cannabis (DUIC)

This study examines the influence that traffic safety culture has on the intention to drive under the influence of cannabis (DUIC) in the next six months. Here, traffic safety culture is defined as “the values and beliefs shared among groups of road users and stakeholders that influence their decisions to behave in ways that improve traffic safety.” To operationalize this definition, a 14-item survey was developed with a binary response format (yes, no) based on a behavioral model predicting intentional DUIC. The sampling plan collected data from drivers at the roadside with the goal of obtaining a Friday daytime and weekend nighttime sample representative of drivers across Washington State (n = 416).The results showed only a small percentage of randomly surveyed drivers in Washington State reported future intention to DUIC (45/416 = 11%). The intention of this small group could be reliably predicted based on certain aspects of their shared culture. Notably, drivers who shared the attitude that DUIC is enjoyable were 3.5 times more likely to report the intention to DUIC in the next six months. Conversely, drivers who shared the belief that cannabis impairs performance and the injunctive norm that people important to them would be disappointed were more than twice as likely not to report future intention to DUIC. Interestingly, the possession of a medical card for cannabis treatment influenced the effects of culture on DUIC intention. The results of this study suggest that strategies that can change DUIC culture amongst at-risk drivers may be effective in reducing such behaviors.     

Mindsets of health and healthy eating intentions

Across two studies, we examined the relation between mindsets of health, expectancy‐value, and eating intentions. We also explored if relations are stronger for African Americans compared to White Americans. In Study 1, we conducted a correlational study (N = 158) to examine initial relations among constructs. In Study 2, we employed an experimental design (N = 205), and randomly assigned participants to either a growth mindset or a fixed mindset of health condition. In both studies, we measured participants’ mindsets of health, expectancy‐value beliefs, healthy eating intentions, past eating habits, and demographics. In Study 1, stronger growth mindsets of health predicted healthier eating intentions. Expectancy‐value beliefs, namely, the extent to which individuals value healthy eating habits and expect to be able to manage their eating, mediated this relation. In Study 2, we successfully manipulated mindsets of health and individuals in the growth mindset condition reported healthier eating intentions, compared to those in the fixed mindset condition. Expectancy‐value beliefs again mediated this link. Race only moderated the relation in Study 1, such that effects of growth mindsets on outcomes (i.e., eating intentions and expectancy‐value beliefs) are stronger for African Americans compared to White Americans. Study 1 provided initial evidence of a relationship between stronger growth mindsets of health and healthier beliefs and intentions. Study 2 offered experimental evidence. We discuss theoretical and practical implications.     

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.     

A connectionist implementation of the theory of planned behavior: association of beliefs with exercise intention.

The theory of planned behavior suggests attitudes are a product of salient beliefs. This study examined whether aggregating salient beliefs was plausible within a more biologically centered information-processing environment. A neural network was used to examine associations among beliefs relating to exercise intention. Data on intentions and behavioral, normative, and control beliefs from 114 respondents were used to train (by error backpropagation) a neural network to associate beliefs with intention. The R-sup-2 between the network's estimated and self-reported intention was.66. The network's representation comprised 6 belief profiles associated with high, moderate, or low behavioral intention. The neural network accommodated complex relationships among beliefs and belief-intention associations and indicated how high-level constructs such as attitudes may be viewed as the best fit (compromise state) between aroused beliefs.     

Australian community responses to the use of genetic testing for personalised health promotion

Personalised genetic health promotion may soon be available and affordable. To explore its likely public acceptance in Australia, a community sample (N = 800) provided quantitative and qualitative responses to a vignette scenario about a hypothetical expert who could test their genes and, based on this genetic profile, provide personalised health promotion advice. Three theoretical models were tested to explicate the process by which cognitive–affective factors of risk beliefs, benefit beliefs, and trust judgements influenced behavioural intentions. Results supported an expert trust model, where general beliefs about the risks and benefits of medical advances and general medical trust had indirect influences, while trust in a specific medical expert had a direct influence, on health promotion intentions. Subjective reasons for intentions included moral concerns, fear, trust, mistrust and a desire to maintain health at any cost. The advent of personalised genetic health promotion may heighten the need for specialised health psychologists.     

Intentions in the Light of Goals

This paper presents a systematic analysis of the various steps of goal-processing and intention creation, as the final outcome of goal-driven action generation. Intention theory has to be founded on goal theory: intentions require means-end reasoning and planning, conflict resolution, coherence. The process of intention formation and intentional action execution is strictly based on specific sets of beliefs (predictions, evaluations, calculation of costs, responsibility beliefs, competence, etc.). The origin of an intention is not necessarily a “desire” (which is just a kind of goal). Intention is a two-layered goal-structure: the intended action(s) to be executed, and the intended outcome motivating that action—with two distinct kinds of “failure”. This belief-goal perspective also allows to examine two stages/types of intention, and the relations and differences between intention “in agenda” (future directed) and intention under execution (intention in action). I will argue that the will is much more than the intention driving an intentional action. I will also claim that intentions are not there just for motivating and regulating intentional actions (from the motor level to more complex behaviors), but that they play also several other important roles.     

Exploring the role of personal normative beliefs in the theory of reasoned action: The problem of discriminating between alternative path models

In the 1967 version of Fishbein's model of the attitude-behaviour relationship a distinction was drawn between personal and social normative beliefs. Personal normative beliefs were later removed from the model on the grounds that they act as an alternative measure of behavioural intention. It is argued that the existing literature does not support this hypothesis and data is presented which indicates that personal normative beliefs are not an alternative measure of behavioural intention. It is argued that personal normative beliefs can be reconceptualized as measuring a person's ideal behavioural intention; a variable which mediates the relationship between attitudes, subjective norms and intentions, Evidence is presented which supports this hypothesis, but it is further demonstrated that an alternative model can be fitted to the present data. It is argued that it is impossible to discriminate between these alternative models on the basis of path analytic techniques, and the implications that this finding has for attitude research are discussed.     

Smoking in movies, implicit associations of smoking with the self, and intentions to smoke

We examined whether identifying with a film character who smokes increases implicit associations of the self with smoking. Undergraduate men were randomly assigned to view film clips in which the male protagonist either smoked or did not smoke. We measured subsequent levels of self-smoking associations using a reaction time task, as well as self-reported beliefs about smoking and smokers. Greater identification with the smoking protagonist predicted stronger implicit associations between the self and smoking (for both smokers and nonsmokers) and increased intention to smoke (among the smokers). Stronger implicit self-smoking associations uniquely predicted increases in smokers' intentions to smoke, over and above the effects of explicit beliefs about smoking. The results provide evidence that exposure to smoking in movies is causally related to changes in smoking-related thoughts, that identification with protagonists is an important feature of narrative influence, and that implicit measures may be useful in predicting deliberative behavior.     

Social Cognitions and Past Behavior as Predictors of Behavioral Intentions Related to Cardiovascular Health

The present study assessed the usefulness of social cognitions shared by several health behavior models for predicting behavioral intentions regarding cardiovascular health, independent of past/current behavior. Over 800 adolescents were administered a cross-sectional survey measuring intentions (regarding cigarette use, fat consumption, physical exercise), social cognitions (severity, vulnerability, benefits, self-efficacy), and past/current behavior. Hierarchical regression analyses, controlling for past/current behavior, showed a varied predictive profile across behavioral intentions. Severity estimates predicted intended cigarette use and fat consumption, while perceived benefits predicted intended physical activity. However, self-efficacy predicted intentions consistently. Collectively, social cognitions contributed an additional 0.8%, 2.5%, and 11. 6%, of the variance in smoking, dietary fat, and exercise intentions, over and above past/current behavior. Theoretical and practical implications are considered.     

Physical activity: the relative associations with cognitive and affective risk beliefs

Abstract

Objective: The role of affectively oriented risk beliefs in explaining health behaviors has not been examined in the context of physical activity or in diverse study populations. We evaluated whether affective risk beliefs account for unique variance in physical activity intentions and behavior above and beyond that accounted for by cognitive risk beliefs.

Design: A cross-sectional survey of socio-demographically diverse US residents (N?=?835; 46.4% no college training; 46.7% minority racial/ethnic ancestry; 42.6% men).

Main outcome measures: Physical activity intentions and behavior.

Results: Hierarchical linear regressions showed that affective risk beliefs accounted for variance in physical activity intentions beyond that predicted by socio-demographics and cognitive risk beliefs (F-change ps<.001). Specifically, intentions were higher among people with higher anticipated regret (ps<.001) and with higher absolute feelings of risk (ps<.05) or worry (ps<.05). There was an indirect relationship between perceived absolute likelihood and intentions through anticipated regret and feelings of risk. Neither cognitive nor affective risk beliefs accounted for variance in physical activity behavior (F-change ps>.05), but unsurprisingly, behavior was positively associated with physical activity intentions (p<.001).

Conclusion: Future interventions could target affective risk beliefs—particularly anticipated regret—to increase intentions, and then add other intervention components to bridge the intention–behavior gap.     

Young children's understanding of belief constraints on intention

One important characteristic of rational action is that our intentions should be consistent with our beliefs. That is, an intention to perform an action should normally be accompanied by a belief that the action will in fact be performed, and be supported by other relevant beliefs. Thus, if the intention is unfulfilled it will have been accompanied by false beliefs. Two studies examined whether 3-year-olds understand these belief constraints on intention. Children were shown films in which actors displayed great surprise and sadness at their failure to bring about the outcomes they intended and expected. They were then questioned about the actors' unfulfilled intentions and false beliefs. In both studies their understanding of unfulfilled intentions was excellent, and significantly better than their understanding of false beliefs. Nevertheless, they also revealed considerable understanding of the beliefs underpinning intentions and, in Study 2, their performance in terms of such beliefs was significantly better than that on standard false-belief tasks. Three-year-olds thus appear to have a threshold understanding of the role of belief in intentional action.     

Returning to Work Following Childbirth: The Relationship Between Intentions and Behavior

College women's intentions to return to work following childbirth were compared to behavior 10 years later. Using an Ajzen-Fishbein model, college intentions were significantly related to how soon a mother returned to work after the birth of her first child. The amount of variance explained was significant for intentions and behavior. College intentions were influenced by perceived consequences, approval of significant referents, and personal control. Return to work was predicted by intention to do so, even though the behavior occurred an average of seven years after the intention was declared. This behavior was more likely to occur among those who had a sense of personal control.     

Predictors of cancer survivors’ response to a community-based exercise program

ObjectiveTo explore the degree to which sociodemographic (i.e., age, sex, ethnicity, weight status, vocational status, marital status), medical (i.e., stage of cancer, treatment status, comorbidity burden), functional (i.e., self-rated health, exercise capacity), cognitive (i.e., exercise self-efficacy beliefs), and behavioural (i.e., program adherence, extra-curricular exercise) factors predicted cancer-related fatigue and quality of life among 224 cancer survivors who participated in the community-based Wellspring Cancer Exercise Program (WCEP).DesignProspective, quasi-experimental single-group repeated measures design.MethodData on predictors and outcomes were collected using self-report and objective measures upon enrollment in the program (week 0), every 10 weeks until program completion (weeks 10, 20, 30), and at 16-weeks follow-up (46 weeks). Data were analyzed using multilevel modeling.ResultsIn general, participants who were working or transitioning to work, rated their health better, and had higher exercise self-efficacy beliefs had lower cancer-related fatigue, and those who rated their health better and had higher exercise self-efficacy beliefs had higher quality of life. Also, there was a significant interaction between time and exercise self-efficacy beliefs for cancer-related fatigue and quality of life such that greater improvements were observed among participants with higher exercise self-efficacy beliefs.ConclusionCancer survivors’ perceptions of their health and their ability to exercise should be fostered to ensure they respond positively to exercise programs in terms of cancer-related fatigue and quality of life.     

A psychosocial model of sun protection and sunbathing in young women: the impact of health beliefs, attitudes, norms, and self-efficacy for sun protection.

A psychosocial model of sun protection and sunbathing as distinct behaviors was developed on 202 young Caucasian women and replicated in an independent sample (n = 207). Proximal outcomes were intention to sun protect and intention to sunbathe; distal outcomes included sun protection and sunbathing behavior measured 5 months later. Objective risk for skin cancer plus 4 classes of psychosocial variables (sun-protective health beliefs, self-efficacy for sun protection, attitudes toward sunbathing, and norms for sunbathing and sun protection) served as predictors. Sun-protective norms and self-efficacy for sun protection predicted only intention to sun protect; sunbathing norms predicted only intention to sunbathe. Susceptibility and advantages of tanning predicted both intention constructs, which, in turn, predicted behavior. These findings distinguish sun protection from sunbathing and provide a basis for intervention design.
