The Role of Beliefs in Mother-Adolescent Conflict: An Application of the Theory of Planned Behavior

This mixed method study applies components of the theory of planned behavior (Ajzen and Fishbein 1980) to mother-adolescent conflict. We examine if three kinds of beliefs—behavioral, control, and normative—predict patterns of family conflict. Forty mother-adolescent dyads completed an open-ended interview, self-report measures of conflict, and an observational measure of family interaction. Hierarchical multiple regressions revealed that mothers’ and adolescents’ beliefs about the costs and benefits of conflict significantly predicted how they interacted and perceived conflict within dyads. Sex differences and differences between mothers and adolescents were identified. This work contributes to our understanding of the role of both general and specific beliefs in family conflict.     

Knowledge and the Prediction of Behavior: The Role of Information Accuracy in the Theory of Planned Behavior

The usefulness of a combined protection motivation and self-efficacy theory as a model of health enhancement was investigated via a persuasive communications paradigm. Self-efficacy expectancy, outcome expectancy (i.e., perceived response efficacy) and outcome value (i.e., perceived social value) of a health-enhancing behavior were manipulated. As predicted, both self-efficacy expectancy and response efficacy had significant main effects on subjects' intentions to perform the health-enhancing behavior. Outcome value had no significant effect on behavioral intentions. Correlational data indicated that response efficacy was the best single predictor of intentions and that self-efficacy expectancy was also a significant predictor of intentions. Outcome value added no predictability. These results support the utility of the combined protection motivation and self-efficacy theory as a model of health enhancement.     

The Proposition of a General Version of the Theory of Planned Behavior: Predicting Ecological Behavior1

The present paper explores whether the theory of planned behavior (TPB) must abandon the notion that perceived behavioral control (PBC) has a direct influence on behavior. In a cross‐sectional survey of 895 Swiss residents, our hypothesis was tested by means of structural equation models. Applied specifically, PBC turned out to be a significant direct predictor of one's performance. A general version of the TPB based on aggregated measures, however, revealed PBC's direct influence on behavior to be nonsignificant and, presumably, a non‐universally applicable and thus nongeneralizable part of the theory. Intention determined 51% to 52% of people's ecological behavior, which supports the claim of a strong attitude‐behavior relation. Attitude, subjective norms, and PBC, the 3 TPB components, account for 81% of intention's variance.     

Predicting Health-Check Attendance Among Prior Attenders and Nonattenders: The Role of Prior Behavior in the Theory of Planned Behavior

A prospective study applying the theory of planned behavior (TPB) to the prediction of attendance at health checks is reported. Conducted in a single general practice, 307 patients completed questionnaires based on the TPB, and were invited to attend a health check. The role of prior behavior in the TPB was assessed in 2 ways. First, it was used to assess the sufficiency of the TPB. The addition of prior attendance behavior led to a significant increase in the prediction of current behavior. Second, its role as a moderator variable was assessed. While the TPB was unsuccessful in predicting attendance behavior among prior attenders, it was able to do so among prior nonattenders. The results are discussed in relation to recent work on decision-making processes.     

The Importance of Affective Beliefs and Attitudes in the Theory of Planned Behavior: Predicting Intention to Increase Physical Activity1

Standard theory of planned behavior (TPB) questions to elicit salient behavioral beliefs may elicit instrumental consequences of behavior, and overlook affective consequences. Two hundred thirteen English adults (35 to 75 years of age) completed a questionnaire that contained closed measures of TPB constructs, and open‐ended questions that asked not only about advantages and disadvantages, but also what respondents would like or enjoy and dislike or hate about being more physically active. Beliefs elicited by affective questions were associated more strongly with a closed affective attitude scale. Beliefs elicited by instrumental questions were associated more strongly with a closed instrumental attitude scale. Closed measures of the standard TPB variables explained 48% of the variance in intention to increase physical activity, while affective attitude explained an additional 11% of the variance. Applications of the TPB should consider affective and not just instrumental determinants of behavior.     

Interaction Effects in the Theory of Planned Behavior: The Interplay of Self-Identity and Past Behavior

This research used a revised theory of planned behavior (TPB) model, which incorporated self-identity and past behavior—and the interaction between these constructs—in order to improve the model's predictive power in relation to consumer behavior (purchasing one's preferred beer). At Time 1, respondents ( N  = 108) completed measures of attitudes, perceived behavioral control, subjective norm, self-identity, past behavior, and intentions. Behavior was assessed 1 week later. All predictors were positively related to intentions. Self-identity and past behavior interacted to influence intentions: Self-identity had a stronger influence on intentions at low, rather than high, levels of past behavior. Intentions and past behavior were predictive of Time 2 behavior. These findings emphasize the need to consider identity issues in the TPB.     

The Role of Self‐identity in the Theory of Planned Behavior: A Meta‐Analysis

The present study used meta‐analysis to evaluate the role of self‐identity in the theory of planned behavior (TPB). Altogether, 40 independent tests (N = 11607) could be included in the review. A large, sample‐weighted average correlation between self‐identity and behavioral intention was observed (r₊ = .47). Multiple regression analyses showed that self‐identity explained an increment of 6% of the variance in intention after controlling for the TPB components, and explained an increment of 9% of the variance when past behavior and the TPB components were controlled. The influence of self‐identity on behavior was largely mediated by the strength of behavioral intentions. Theoretical implications of the findings are discussed.     

计划行为模型在HIV性风险行为领域的应用与发展*

整理和回顾了计划行为模型在HIV性风险行为领域的应用与进展。该模型在不同文化背景、不同样本中,对于HIV性风险行为呈现良好的解释力,但是其整体预测力及内部变量的显著程度仍不时波动。21世纪以来,通过核心变量操作化、新变量引入和结构关系调整,模型获得了较大的扩展和完善。但在模型效度再检验、纳入社会性别视角、克服个体行为模型缺陷,以及强化模型的干预适用性方面仍有较大的发展空间     

Modifying Beliefs and Attitudes to Exceeding the Speed Limit: An Intervention Study Based on the Theory of Planned Behavior1

This study builds on previous theory of planned behavior (TPB) studies in which we identified the beliefs and values which predict intention to commit driving violations. Four short experimental videos were developed in order to assess the effectiveness of an intervention grounded in the TPB. Three of the videos featured the major constructs of the TPB model. The fourth video featured anticipated regret, an addition to the TPB model which had previously been shown to add significantly to its predictive performance (Parker, Manstead, & Stradling, 1995). Results indicated that two of the videos brought about statistically significant belief changes with respect to scores on TPB items, and significant changes in general attitudes toward speeding. Discussion centers on the problems encountered in operationalizing the TPB constructs and on the potential of theory-based interventions to induce attitude change.     

计划行为理论述评

计划行为理论是社会心理学中最著名的态度行为关系理论,该理论认为行为意向是影响行为最直接的因素,行为意向反过来受态度、主观规范和知觉行为控制的影响。计划行为理论在国外已被广泛应用于多个行为领域的研究,并被证实能显著提高研究对行为的解释力和预测力。文章对这一理论进行了全面概述,包括理论的提出、内涵、测量方法以及理论研究的新进展,并指出了理论仍存在的问题和今后的研究方向     

The Theory of Planned Behavior: Some Measurement Issues Concerning Belief-Based Variables

The theory of planned behavior presents clear operational definitions of attitudes, subjective norm, perceived behavioral control, and each of their corresponding belief-based measures. Theoretically, the direct and indirect measures of a given construct must be closely correlated. Empirical results, however, indicate that this is not always the case. In the present study, 2 of the factors that could be responsible for this situation-namely, the scaling of the variables defining each belief-based construct and the adequacy of using an expectancy-value model within the belief-based measures-were verified among a data set of 16 studies concerned with the application of the theory of planned behavior to the field of health. The results indicate that the scaling method used affected the correlation coefficients between indirect and direct measures. However, the face validity of these scaling methods must be demonstrated. The results also support the idea that, in most cases, using the expectancy-value model is no better than using only one arm of the belief-based measure.     

Personality,the Theory of Planned Behavior,and Exercise: A Unique Role for Extroversion's Activity Facet1

The primary purpose of this study was to determine if the theory of planned behavior (TPB) mediated the relationship between selected personality traits (i.e., extroversion, neuroticism, and conscientiousness) and exercise behavior using structural equation modeling. Based on previous research, it was hypothesized that extroversion (E) would have a significant direct effect on exercise behavior while controlling for the TPB. A secondary purpose was to explore whether the facets of these personality domains had significant effects on TPB constructs or exercise behavior while controlling for the general personality domains. Female undergraduate students (N= 301) completed measures of the TPB, the Five‐Factor model of personality, and a 1‐month exercise behavior follow‐up. Model 1 resulted in a direct effect of E on exercise behavior. Model 2 suggested a significantly better fit when direct effects of E's activity facet were freed for estimation. Moreover, freeing these effects rendered the effects of general E nonsignificant. It was concluded that the direct effect of E on exercise behavior found in previous research might be explained entirely by the activity facet of E.     

Distracted pedestrians in crosswalks: An application of the Theory of Planned Behavior

Thousands of adult pedestrians are killed or injured each year. In spite of ever growing knowledge of correlates of risk pedestrian behavior, much remains to be learned. A small body of research has applied the Theory of Planned Behavior (TPB) to the problem of risky crossing decisions. We employed TPB to examination of intentions to cross under varying types of distraction. Eighty adults completed measures of injury exposure, followed by a questionnaire structured around TPB assessing intentions to cross streets under common conditions of self-imposed distraction. Results were similar to other research, suggesting attitude and perceived behavioral control predicted intentions to cross streets while distracted. Results are discussed in the context of similar studies, and with regard to future directions and injury prevention efforts.     

COVID-19 Help-Seeking Behaviors: Application of the Theory of Planned Behavior

The novel coronavirus disease (COVID-19) is highly contagious. More than 247 million cases have been confirmed by the end of October 2021. Seeking help earlier may slow the spread of COVID-19 because it may help in early detection of infected cases, and it facilitate tracing those who were with close contact with infected cases. The purpose of this study is to identify participants’ intentions toward COVID-19 seeking help and the factors affecting their decision. This is a cross-sectional study. An online survey using Google Forms was used for data collection. Hierarchical multiple regression analysis was used to explain intentions to seek help for COVID-19. The concepts included in the Theory of Planned Behavior and COVID-19 knowledge were used as predictors. The sample included 780 participants, with an average age of 28.60±9.86 years old. Most of the sample were female (67.4%) and having a bachelor’s degree (72.7%). Participants showed high level of knowledge regarding COVID-19, 73% of the sample had a total knowledge score equal to or higher than 85%. Also, participants had high positive attitudes and high intentions to seek help for COVID-19. The four predictors: Attitudes towards COVID-19, subjective norm, perceived behavioral control, and COVID-19 knowledge significantly explained intentions to seek help. Participants had high intentions to seek help for COVID-19, which was related to having positive attitudes toward seeking help, high social approval, high perceived controllability, and high COVID-19 knowledge levels. Regular awareness campaigns during early stages of pandemics should be performed to improve attitudes and knowledge level, which may improve prevention measures, and promote help seeking behaviors. Consequently, this may facilitate early detection of cases, and slow the spread of pandemics.     

The Theory of Planned Behavior and Breast Self-Examination: Distinguishing Between Perceived Control and Self-Efficacy

This paper reports an application of the theory of planned behavior (TPB) to the prediction of breast self-examination (BSE) intentions and behavior. The study also considered the distinction between perceived control and self-efficacy within the TPB and the additional predictive utility of past behavior. A sample of 95 women completed questionnaires based on the TPB and were followed up at 1 month. Support for the distinction between perceived control and self-efficacy was provided by principal components analysis. The TPB was found to be highly predictive of intention to perform BSE and subsequent BSE behavior. Regression analyses revealed self-efficacy and attitude to be predictive of intention to perform BSE. Intention, in turn, was the sole predictor of BSE at 1-month follow-up. Past behavior was found to explain additional variance in intention, but not BSE behavior at 1-month follow-up. The results are discussed in relation to the conceptual status of the perceived behavioral control construct, and the practical implications of the results are highlighted.     

Predicting Dental Flossing Behavior: The Role of Implicit and Explicit Responses and Beliefs

The study examined the ability of implicit responses to predict dental flossing behavior. It was hypothesized that adding implicit responses would increase the predictive power of models containing variables suggested by social cognitive theories. To test the hypothesis, 125 participants completed measures of social cognitive variables (e.g., self-efficacy, task-efficacy, planning intention, behavior intention) and performed a procedure designed to measure their implicit responses to flossing. Flossing behavior was measured with retrospective self-reports and a follow-up measure of flossing. As predicted, the addition of implicit responses to models containing the social cognitive variables increased the predictive power of the models for both the self-report and follow-up measures.     

Stress and the Theory of Planned Behavior: Understanding Healthy and Unhealthy Eating Intentions

Unhealthy and healthy eating intentions are predicted in a sample of 154 university students by the theory of planned behavior variables, in interaction with life stress. Specifically, subjective norms and perceived behavioral control (PBC) are shown to interact with life stress in relation to intentions to eat unhealthy foods, such that at high stress, the effects of subjective norms and PBC are attenuated. Implications are discussed for studies involving the planned behavior model and the study of life stress and unhealthy eating, for the theory of planned behavior more broadly, as well as for interventions targeting university students' eating intentions.     

The Oneness Beliefs Scale: Connecting Spirituality with Pro‐Environmental Behavior

The inherent unity of all phenomena, or oneness, is a central concept of mysticism, but there have heretofore been no measures of oneness beliefs. We developed the Oneness Beliefs Scale, with spiritual and physical oneness subscales. The spiritual oneness subscale fills a need in the field for a short, reliable measure of spirituality not characterized by the language of traditional Western religiousness. The physical oneness subscale allows researchers to juxtapose spiritual beliefs with a nonspiritual, materialist counterpart. We found that spiritual oneness beliefs were more strongly related to mystic experiences and spirituality than to traditional religiousness. Physical oneness was not strongly associated with either religiousness or spirituality. Both spiritual and physical oneness were positively associated with pro‐environmental attitudes but not with depression, anxiety, or negative affect. Spiritual oneness was a better predictor of pro‐environmental attitudes than was religiousness. Spiritual oneness also predicted donating to a pro‐environmental group, making this to our knowledge the first empirical study to show a positive association between a religion or spirituality measure and observed, rather than self‐reported, pro‐environmental behavior.
