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.     

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.     

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.     

The theory of planned behavior

Research dealing with various aspects of the theory of planned behavior (Ajzen, 1985 and Ajzen, 1987) is reviewed, and some unresolved issues are discussed. In broad terms, the theory is found to be well supported by empirical evidence. Intentions to perform behaviors of different kinds can be predicted with high accuracy from attitudes toward the behavior, subjective norms, and perceived behavioral control; and these intentions, together with perceptions of behavioral control, account for considerable variance in actual behavior. Attitudes, subjective norms, and perceived behavioral control are shown to be related to appropriate sets of salient behavioral, normative, and control beliefs about the behavior, but the exact nature of these relations is still uncertain. Expectancy-value formulations are found to be only partly successful in dealing with these relations. Optimal rescaling of expectancy and value measures is offered as a means of dealing with measurement limitations. Finally, inclusion of past behavior in the prediction equation is shown to provide a means of testing the theory's sufficiency, another issue that remains unresolved. The limited available evidence concerning this question shows that the theory is predicting behavior quite well in comparison to the ceiling imposed by behavioral reliability.     

Evaluation of a school-based intervention programme to promote physical activity: an application of the theory of planned behavior

The Theory of Planned Behavior provides a useful framework to study attitudes toward participation in physical activity. The objective of the study was to test the effectiveness of an intervention in manipulating the variables of the Theory of Planned Behavior and exercise habits with 366 high school students (M = 14.2 yr., SD = .7; 201 boys and 165 girls). The students were divided into intervention and control groups. A questionnaire to measure components of the theory, and the Baecke Questionnaire of Habitual Activity measuring exercise habits, were administered. The intervention lasted 12 wk. and included posters and lectures promoting participation in physical activity. Analyses showed the intervention was effective in improving attitudes towards physical activity, perceived behavioral control, intention, and self-reported actual behavior, but it was ineffective for improving attitude strength, subjective norms, and role identity. The results provide useful information for physical education teachers interested in promoting students' positive attitudes towards physical activity.     

Factorial invariance of the theory of planned behavior applied to physical activity across gender,age, and ethnic groups

Objectives:The present study assessed the generalizability of the Theory of Planned Behavior (TPB) applied to physical activity and to examine if the TPB operates equivalently across gender, age, and ethnic sub-groups.Design/Methods:Measurement equivalence was evaluated for gender (male/female), age (19–34/35–54/55+) and ethnicity (Japanese/Hawaiian or part Hawaiian/Filipino/White) in a random sample (n = 3533) using Multisample Structural Equation Modeling.Results:Measurement equivalence was found for all variables and for their intercorrelations. Of the 100 possible TPB variable relationships between groups, only 6 were significant. The differences were found in explained variances of physical activity.Conclusions:The findings indicate that TPB measures apply over a range of population sub-groups, and should be considered comprehensively when designing interventions.     

Health enhancing physical activity as perceived in interviews based on the theory of planned behaviour

Abstract

The perception of behaviours from two categories of health enhancing physical activity (HEPA): outdoor aerobic exercise (OAE) and everyday commuting activity (ECA) was examined in a sample of middle-aged persons (N= 50). A focused semi-standardised interview was constructed on the bases of the components of the Theory of Planned Behaviour (TPB). The participants perceived OAE behaviours predominantly from the viewpoint of exercise and those of the ECA from that of the fluency of daily routines. They considered the OAE as sensible and associated it with positive health or fitness outcomes, but only those practising it also attributed positive psychological effects to OAE behaviours. A slightly better congruence with the TPB was found for the OAE behaviours than for those of the ECA. The difference is discussed in the light of the higher degree of decisional control with the OAE behaviours and the greater psychological heterogeneity of the ECA.     

Students’ individual interest in physical education: Development and validation of a questionnaire

Identifying the specificity of students’ individual interest in physical education is necessary to capture the different facets of this construct. In contrast to existing questionnaires in education which assess the multidimensionality of individual interest, the current scale used in physical education consists of a single‐item measurement which rates students’ individual interest for multiple physical activities taught during lessons. Even if this single‐item rating provides a basis for classifying interest relative to others, it does not provide information about the nature and internal components of individual interest. Therefore, the purpose of this study was to develop a valid and reliable questionnaire measuring the multidimensionality of students’ individual interest in physical education. Four stages were followed: (1) the development of a preliminary version based on the findings of a literature review on individual interest and a committee process validation; (2) a first study conducted on 481 secondary school students to establish the factor structure, and internal reliability of this questionnaire; (3) a second study based on 243 secondary school students to confirm its factor structure and to test its temporal stability; and finally, (4) a third study with 253 students to test its concurrent validity. The final form of the questionnaire consists of a three‐factor structure based on 14 items that measure students’ individual interest in physical education: positive affect and willingness to reengage (five items), stored utility value (four items), and stored attainment value and knowledge‐seeking intentions (five items).     

Development and validation of the organisational cooperation questionnaire

IntroductionCooperation is an essential framework for the functioning of organisations and society. The limitations of current measures of organisational cooperation led us to construct the measure herein presented.ObjectiveThe paper aims to describe the development and psychometric validation of an organisational cooperation measure based on how the cooperating members view and experience the cooperation process.MethodBased on relevant literature, the items were built and submitted to a panel of experts and fine-tuning procedures. The instrument (31 items) was applied to 1354 employees in local authorities. Exploratory and confirmatory factor analysis were performed (2 sub-samples), as well as validation procedures through Pearson correlation with the Knowledge Management Questionnaire.ResultsResults showed good statistical indicators of a 22-items three-factor structure: principles of cooperative relationship; formal regulation of cooperation; and cooperation focused on organisational mission. The factors are interpreted theoretically and present high internal consistency. The validation process suggests the suitability of the instrument for the population studied.ConclusionThis instrument can be used as a starting point for organisational intervention when cooperation-intensive processes are relevant. It can be useful to characterize the existing cooperation in organisations and to foster cooperation in organisations, especially in the intended dimensions. Future studies can apply the instrument to various sectors of activity. It will also be worth studying cooperation in its relationship with other organisational variables, namely those concerning cooperation-intensive processes.     

Development and validation of the self-harm reasons questionnaire

Understanding the reasons for self-harm (SH) may be paramount for the identification and treatment of SH behavior. Presently, the psychometric properties for SH reason questionnaires are generally unknown or tested only in non-inpatient samples. Existing inpatient measures may have limited generalizability and do not examine SH apart from an explicit intent to die. The present study examined a newly developed, self-report measure of reason for self-harm. The Self-Harm Reasons Questionnaire (SHRQ) was administered to 143 undergraduate students. Results indicated that SH reasons covaried in meaningful and internally consistent ways, with subgroups of SH reasons correlating with hypothesized concomitants of SH, such as depressive symptoms. Findings have implications for prevention and intervention and the SHRQ offers a new, albeit preliminary, means by which to examine SH reasons in a non-inpatient sample.     

Development and validation of the predrinking motives questionnaire

Elaborating on instruments for U.S. university students, we developed and validated the predrinking (drinking before going out) motives questionnaire (PMQ) for general populations of young adults. In popular nightlife areas in Switzerland, 316 predrinkers aged 16–25 (48% women) were recruited. Focus group interviews and exploratory and confirmatory factor analyses yielded a three‐factor measure, with a structure that was invariant across linguistic regions, gender, age, and student status. “Fun/intoxication” motives were associated with predrinking but “conviviality” and “facilitation” motives were not. Men scored higher on “facilitation” than women and those from the French‐speaking region scored higher on “conviviality” than German‐speaking participants. Although yet to be replicated in other countries, the PMQ appears to be an appropriate general measure of predrinking motives.     

Personality and social cognitive influences on exercise behavior: adding the activity trait to the theory of planned behavior

Objectives: To replicate findings for a direct effect of the activity personality trait on exercise behavior while controlling for the Theory of Planned Behavior (TPB), and to investigate a possible moderating effect for gender.Method: Undergraduate students (N=298) completed measures of the TPB, activity trait, and a two-week follow-up of exercise behavior.Results: The activity trait had a significant (p<0.01) direct effect on both exercise intention and behavior while controlling for the TPB, with no moderating effect of gender (p>0.05).Conclusions: The activity trait predicts exercise intention and behavior independent of social cognition even over a short two week period. The TPB may need to broaden its measurement domain in order to mediate the effect of personality on behavior. Moreover, exercise practitioners may need to consider personality when developing interventions.     

The physical self-attribute questionnaire: development and initial validation

The Physical Self-attribute Questionnaire was developed for use in conjunction with the Physical Self-perception Profile to model cognitive facets of perceived competence, certainty, importance, and discrepancy from ideal to each of the physical subdomains measured by the latter (Strength, Attractive Body, Condition, and Sport). To this end, two studies were conducted. Study 1 examined the factor structure, test-retest reliability, and validity of the questionnaire in a sample of 154 (28 men, 126 women) undergraduate health students. Reliability and validity were acceptable, and confirmatory factor analysis indicated good fit for a four-factor solution. In Study 2, the reliability, validity, and factor structure was again confirmed in a sample of 120 (83 men, 37 women) undergraduate students recruited from exercise classes. Results of these two studies suggest that the Physical Self-attribute Questionnaire is a viable tool to measure the underlying cognitive facets of subdomain-specific physical self-esteem.     

Mindfulness and the intention-behavior relationship within the theory of planned behavior

The present study examined moderating effects of mindfulness on the intention-behavior relationship within the theory of planned behavior. Mindfulness describes a quality of consciousness characterized by heightened clarity and awareness of present experiences and functioning. Study 1 showed that mindfulness moderated the intention-behavior relationship in a leisure-time physical activity context such that intentions predicted physical activity among mindful individuals and not among less-mindful individuals. Study 2 measured counterintentional habits relating to binge-drinking and found that habitual binge-drinking obstructed the enactment of physical activity intentions among individuals acting less mindfully but not among individuals acting mindfully. Finally, Studies 1 and 2 demonstrated that the effects of mindfulness on physical activity were independent of effects observed for habit and variables contained in the theory of planned behavior. These findings suggest that mindfulness is a useful construct that helps understand the intention-behavior relationship within the theory of planned behavior.     

The theory of planned behavior and healthy eating.

Application of the theory of planned behavior (TPB) to healthy eating in 144 health promotion clinic attendees is reported. Respondents completed self-report TPB measures after the clinic (Time 1) and 6 months later (Time 2) with a measure of perceived past behavior. Intention stability was assessed on Time 1-2 differences. Six years later (Time 3), respondents completed measures of healthy eating intentions and behavior. Intentions were predicted by attitudes, perceived behavioral control, and perceived past behavior (cross-sectionally). Healthy eating behavior (Time 3) was predicted from intentions (Time 2). As intention stability increased, intentions and perceived past behavior became stronger and weaker predictors of behavior, respectively. Implications for understanding health cognitions in long-term performance of health behavior are discussed.     

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.     

Development and validation of the traffic displaced aggression questionnaire

Displaced aggression is defined as the aggression conducted against someone or something that is not considered to be the trigger of the emotional state of the aggressor. Whereas it has been deeply studied in a general context, to date, very few studies have analysed it in the specific context of driving. Considering the inexistence of instruments to assess it, the aim of the current research was to develop and validate a self-report in order to assess displaced aggression in the driving context. A sample of 467 participants (66.8% female, M_age = 34.74) filled in a set of questionnaires including the 29 items that were designed to assess traffic displaced aggression, as well as other instruments measuring different ways of expressing both general and driving aggression. The results of both Parallel Analysis (PA, sub-sample 1) and Confirmatory Factor Analysis (CFA, sub-sample 2) showed a good fit of the two-factor model, retaining 20 out of the initial 29 items. The first factor was labelled as Displaced aggression due to the anger generated outside the vehicle (6 items, α = 0.83), whereas the second factor was labelled as Displaced aggression due to the anger generated inside the vehicle (14 items, α = 0.91). Both factors, as well as the total score, showed good results regarding convergent and divergent validity. Practical implications of the results, future research lines and limitations of the current study are discussed.     

Development and validation of the penn state worry questionnaire

The present report describes the development of the Penn State Worry Questionnaire to measure the trait of worry. The 16-item instrument emerged from factor analysis of a large number of items and was found to possess high internal consistency and good test-retest reliability. The questionnaire correlates predictably with several psychological measures reasonably related to worry, and does not correlate with other measures more remote to the construct. Responses to the questionnaire are not influenced by social desirability. The measure was found to significantly discriminate college samples (a) who met all, some, or none of the DSM-III-R diagnostic criteria for generalized anxiety disorder and (b) who met criteria for GAD vs posttraumatic stress disorder. Among 34 GAD-diagnosed clinical subjects, the worry questionnaire was found not to correlate with other measures of anxiety or depression, indicating that it is tapping an independent construct with severely anxious individuals, and coping desensitization plus cognitive therapy was found to produce significantly greater reductions in the measure than did a nondirective therapy condition.     

Measuring implementation intentions in the context of the theory of planned behavior

The usefulness of measuring implementation intentions in the context of the theory of planned behavior (TPB) was explored among 112 Norwegian college students. They responded to a questionnaire measuring past behavior, perceived behavioral control, behavioral intentions, implementation intentions, and actual performance of regular exercising and recycling of drinking cartons. Implementation intentions were measured using five items relating to recycling and four items relating to exercise, which showed satisfactory internal consistencies. Consistent with the main prediction, the presence of implementation intentions was related to performing the two behaviors, although behavioral intentions were the strongest determinant for both behaviors. The results suggest that the TPB may benefit from inclusion of the concept of implementation intentions to provide a more complete understanding of the psychological process in which motivation is translated into action.
