Sports spectator behavior: a test of the theory of planned behavior

The theory of planned behavior has been applied to sports and exercise behaviors. According to this theory, human intention to take action in a specific context is guided by three antecedents: attitude, subjective norm, and perceived behavioral control. Behavioral intention mediates the relationships between these three considerations and its ultimate performance. However, this theory has seldom been applied to the behaviors of spectators of sporting events. A sample of 269 volleyball spectators in Taiwan was studied to examine whether people's intention mediated their attitudes, subjective norms, and perceived behavioral control toward a given behavior, watching the 2010 Fédération Internationale de Volleyball World Grand Prix in Taipei. Regression analyses did not support behavioral intention as a mediator. This result is discussed in the context of planned behavior.     

Integrating five-factor model facet-level traits with the theory of planned behavior and exercise

ObjectivesThe purpose of this study was to examine direct, indirect, and moderating links between facet-level personality traits of the five-factor model, the theory of planned behavior (TPB) constructs [Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211.], and exercise behavior.DesignCross-sectional.MethodUniversity students (N = 507) completed the NEO-PI-R [Costa, P. T., McCrae, R. R. (1992). The NEO-PI-R personality inventory: Professional manual. Odessa, FL: Psychological Assessment Resources.], the Leisure-time Exercise Questionnaire [Godin, G., Shephard, R. J. (1985). A simple method to assess exercise behavior in the community. Canadian Journal of Applied Sport Science, 10, 141–146.], and measures assessing the TPB constructs.ResultsPreliminary analysis revealed the extraversion and conscientiousness facet-level traits of activity and self-discipline respectively were independent predictors of exercise behavior. An integrated structural model with both facet-level traits revealed that 46% of the variance in exercise behavior and 70% of the variance in intention was explained. Significant indirect effects of activity and self-discipline and the TPB constructs of affective attitude, instrumental attitude, and subjective norm, on exercise behavior through intention and perceived behavioral control were also observed. Finally, the anxiety facet trait of neuroticism significantly moderated the intention–behavior relationship.ConclusionsOur findings showed that the facet-level personality traits of activity and self-discipline are important motivational variables that link the TPB constructs to exercise behavior. Future research that integrates personality with the TPB within experimental interventions is warranted.     

Can the theory of planned behavior predict the maintenance of physical activity?

This study tested the ability of the theory of planned behavior to predict actual participation in physical activity and explored the development of activity habits in a 12-week longitudinal study. People enrolling in a gymnasium (N = 94) completed standard theory of planned behavior measures at baseline and follow-up; behavior was monitored objectively in the intervening period. The data were analyzed by using both standard and repeatable events survival analysis. Results showed that (a) perceived behavioral control was significantly predictive of intentions and actual behavior, (b) stable exercise habits developed in the first 5 weeks of the study, and (c) successful prior performance enhanced perceptions of behavioral control. The implications for developing theory-based interventions that promote the maintenance of health behavior are discussed.     

Social Cognitive Determinants of Blood Donation

This article reports two studies designed to test a theory of planned behavior-based model of blood donation. In Study 1 ( n = 136), self-efficacy and self-identity accounted for unique variance in behavioral intention. Study 2 ( n = 172) extended Study 1: self-efficacy, perceived control over behavior (PCB), self-identity, and moral norm were all independently predictive of intention; behavioral intention predicted a proxy measure of behavioral enaction. Both studies provided evidence to support a distinction between self-efficacy and PCB, and for the inclusion of self-identity and moral norm into the model. Belief-based measures discriminated intenders from nonintenders, and beliefs that accounted for unique variance in self-efficacy and PCB were identified. The findings are discussed in relation to using models such as the theory of planned behavior to intervene in social and health behaviors.     

Relationships among the theory of planned behavior,stages of change,and exercise behavior in older persons over a three year period

Abstract

The present study examined the relationships among the theory of planned behavior (TPB), stages of change, and exercise behavior in 131 older persons over a three year period. Participants completed a baseline questionnaire by mail that assessed attitude, perceived control, subjective norm, intention, and stage and then received a telephone call three years later in which current exercise stage and behavior were assessed. Path analyses showed that (a) TPB constructs were significant predictors of exercise stage, (b) intention mediated the effects of TPB constructs on exercise stage, and (c) exercise behavior was best predicted by intention rather than stage. Results were interpreted as providing evidence for the long term predictive validity of TPB in the exercise domain and as questioning the necessity of combining both intention and stage in a single predictive model.     

Relationships between self-determination theory and theory of planned behavior applied to physical activity and exercise behavior in chronic pain

This study examined the relationships between self-determination theory (SDT) and theory of planned behavior (TpB) applied to physical activity and exercise behavior (PA&E) in people with chronic pain. Two hundred and eleven adults with chronic musculoskeletal pain (28 males and 183 females, age range 18 to 82 years, mean age 43 years) were recruited from online support groups and clinic networks in the United States. Participants completed SDT measures relevant to PA&E on perceived autonomy support, autonomy, competence, and relatedness, as well as TpB measures relevant to PA&E on intention, attitudes, subjective norms, and perceived behavioral control. Correlational techniques and canonical correlation analysis were performed to examine the relationships and variance within and between theoretical dimensions. Overall, the SDT set accounted for 37% of the TpB variance and the TpB set accounted for 32% of the SDT set variance. The results indicate there are statistical similarities and differences between concepts in SDT and TpB models for PA&E. Using both empirical guidance and clinical expertise, researchers and practitioners should attempt to select and integrate non-redundant and complementary components from SDT, TpB, and other related health behavior theories.     

Threshold assessment of attitude,subjective norm,and perceived behavioral control for predicting exercise intention and behavior

According to the theory of planned behavior (TPB), attitude, subjective norm, and perceived behavioral control (PBC) are hypothesized to have linear associations with intention and behavior. However, no previous research has examined this hypothesized linearity across scale responses. Further, no study using social cognitive measures has detailed the incremental increases in the proportion of people meeting the American College of Sports Medicine's (ACSM) exercise guidelines across scale responses. The purpose of this study was to examine mean scores of intention and behavior and detail the proportion of participants meeting ACSM's exercise guidelines for each TPB construct response category (i.e. 1–7). Participants were university undergraduates (N=585) who completed measures of the TPB and a 2-week follow-up of exercise behavior. Results were evaluated using effect sizes (d,w) and p-levels, and provided general support for the linear effects of affective and instrumental attitude, but PBC and subjective norm were identified as having specific thresholds. Further, thresholds of positive, but not negative, exercise social cognition were identified for meeting ACSM's criteria with the exception of affective attitude. Threshold analysis was discussed as a novel way of analyzing TPB data by providing additional information about the expected success of intervention efforts focused on TPB constructs.     

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.     

Drivers' compliance with speed limits: an application of the theory of planned behavior

The theory of planned behavior (TPB; I. Ajzen, 1985) was applied to drivers' compliance with speed limits. Questionnaire data were collected for 598 drivers at 2 time points separated by 3 months. TPB variables, demographic information, and self-reported prior behavior were measured at Time 1, and self-reported subsequent behavior was measured at Time 2. In line with the TPB, attitude, subjective norm, and perceived control were positively associated with behavioral intention, and intention and perceived control were positively associated with subsequent behavior. TPB variables mediated the effects of age and gender on behavior. Prior behavior was found to moderate the perceived control-intention and perceived control-subsequent behavior relationships. Practical implications of the findings for road safety and possible avenues for further research are discussed.     

Predicting People’s Intention to Donate Their Body to Medical Science and Research

Predictors of people’s intention to register with a body bequest program for donating their deceased body to medical science and research were examined using standard theory of planned behavior (TPB) predictors (attitude, subjective norm, perceived behavioral control) and adding moral norm, altruism, and knowledge. Australian students (N = 221) at a university with a recently established body bequest program completed measures of the TPB’s underlying beliefs (behavioral, normative, and control beliefs) and standard and extended TPB predictors, with a sub-sample reporting their registration-related behavior 2 months later. The standard TPB accounted for 43.6%, and the extended predictors an additional 15.1% of variance in intention. The significant predictors were attitude, subjective norm, and moral norm, partially supporting an extended TPB in understanding people’s body donation intentions. Further, important underlying beliefs can inform strategies to target prospective donors.     

Predicting attendance at peer-assisted study sessions for statistics: role identity and the theory of planned behavior

Using a prospective study of 77 1st-year psychology students' voluntary attendance at peer-assisted study sessions for statistics, the authors tested the addition of role identity to the theory of planned behavior. The authors used a revised set of role-identity items to capture the personal and social aspects of role identity within a specific behavioral context. At the commencement of the semester, the authors assessed the students' attitudes, subjective norm, perceived behavioral control, role identity, and intention. The authors examined the students' class attendance records 3 months later. Attitudes and perceived behavioral control predicted intention, with intention as the sole predictor of attendance. Role identity also predicted intention, reflecting the importance of the student role identity in influencing decision making related to supplementary academic activities.     

Moral Concerns and Consumer Choice of Fresh and Processed Organic Foods1

This study used the theory of planned behavior (TPB) to examine the impact of moral concerns on intention to buy organic apples and organic pizza. Initially, beliefs were elicited from a group of 30 people using a combination of the traditional TPB elicitation technique supplemented by direct questioning about emotions associated with the behavior. The questionnaire—which included measures of behavioral beliefs, attitudes, subjective norm, perceived behavioral control, and measures of moral norms (worded both positively and negatively)—was completed by 281 people. Multiple regressions showed that for both foods, the positive moral component added significantly to the prediction of intention, while negative ones did not. Also, affective attitude was a strong predictor of intention for both foods.

Testing an extended theory of planned behavior to predict young people's intentions to join a bone marrow donor registry

An extended theory of planned behavior (TPB) was used to understand the factors, particularly control perceptions and affective reactions, given conflicting findings in previous research, informing younger people's intentions to join a bone marrow registry. Participants (N = 174) completed attitude, subjective norm, perceived behavioral control (PBC), moral norm, anticipated regret, self‐identity, and intention items for registering. The extended TPB (except PBC) explained 67.2% of variance in intention. Further testing is needed as to the volitional nature of registering. Moral norm, anticipated regret, and self‐identity are likely intervention targets for increasing younger people's bone marrow registry participation.     

Predictors of smoking cessation in Taiwan: using the theory of planned behavior

This study aimed to explore the factors predicting the intention to quit smoking and the subsequent behavior 6 months later using the theory of planned behavior (TPB). Data were obtained from 145 smokers who attended a smoking cessation clinic in a community hospital. All participants completed a questionnaire which included demographic information, TPB-based items, perceived susceptibility and previous attempts to quit. The actual quitting behavior was obtained by follow-up phone calls 6 months later. The TPB constructs explained 34% of the variance in intention to quit smoking. By adding perceived susceptibility, the explained variance was significantly improved to 40%. The most important predictors were perceived behavior control and perceived susceptibility, followed by attitude. Subjective norm did not contribute to the prediction of intention. Attitude and perceived behavior control contributed to the prediction of actual quitting behavior, but intention, subjective norm and perceived susceptibility did not. Our findings support that the TPB is generally a useful framework to predict the intention to quit smoking in Taiwan. The inclusion of perceived susceptibility improved the prediction of intention. With regards to successfully quitting, attitude and perceived behavior control played more crucial roles than other TPB constructs. Smoking cessation promotion initiatives focusing on reinforcing cessation belief, enhancing a smoker’s perception of their capability to quit smoking, and persuading smokers that they can overcome cessation barriers to cessation could make subsequent interventions more effective.
