Studying, Practicing, and Mastering: A Test of the Model of Goal-Directed Behavior (MGB) in the Software Learning Domain

The present study tested the model of goal-directed behavior (MGB). The model proposes that behavioral intentions to perform instrumental behaviors are primarily motivated by desires to perform the acts. In turn, desires mediate the effects of attitudes, subjective norms, perceived control, and anticipated emotions on intentions. Construct validity for MGB variables is assessed, and the predictive utility of the MGB is compared with that of the theory of planned behavior (TPB). College students ( N = 102) provided measures for MGB and TPB variables while participating in a training program to use statistical software. We focused on two goal-related instrumental behaviors: studying handbooks and practicing with the package. The results show that the MGB accounts for a greater proportion of variance in intentions and instrumental behaviors than does TPB. Although desires mediate most of the effects of other predictors on intentions to perform the instrumental behaviors, it is proposed that when the behavior is normatively relevant, or when self-efficacy appraisals play a major role, subjective norms and perceived behavioral control may directly affect intentions.     

Group processes in food choices: The role of ethnic identity and perceived ethnic norms upon intentions to purchase ethnical food products

A study tested an extended Theory of Planned Behaviour (TPB) model, inclusive of measures of ethnical identification and perceived ethnic group norms, in the ethnical food purchasing domain. One hundred and thirty‐five Jamaicans, living in the Brixton neighbourhood, London, were administered a self‐reported questionnaire measuring the classical TPB components (attitudes, subjective norms, perceived behavioural control, behavioural intentions) plus three additional components: identification with the Jamaican group, perceived norms of the Jamaican group and past behaviour. Results of hierarchical multiple regressions showed that past behaviour, ethnical identification and perceived group norms explain an additional proportion of variance in intentions, independently of attitudes, subjective norms and perceived control. A two‐way interaction, between ethnical identification and perceived group norms, was detected. A stronger relation between group norms and intentions emerged among high ethnical identifiers. Theoretical and practical implications are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

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     

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.     

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.     

Organ donation intentions and behaviors: application and extension of the theory of planned behavior

Organ donation intentions and behaviors were investigated using a traditional and extended theory of planned behavior (TPB). In study 1, attitudes, subjective norms, and perceived behavioral control were associated with intentions to engage in donation behaviors in a student sample (all p ≤ .02), and intentions significantly predicted behavior 2 months later (p < .001). Study 2 utilized a community sample of Catholic, Jewish, and Muslim individuals. Measures of affect and religious attitudes were added to the traditional TPB, increasing the variance in intentions accounted for by the model, F(7, 181) = 6.94, p < .001. The studies support the use of an extended TPB in predicting donation‐related intentions and behaviors and suggest potential targets of interventions to promote donation.     

Modeling antecedents of university students' study behavior and grade point average

Two prospective surveys tested theory‐based models of university students' study behavior and grade point average (GPA). The theory of planned behavior (TPB) and personality systems interaction (PSI) theory were tested. The TPB fitted the data for self‐reported study but was less useful when applied to GPA. Some support for PSI theory was found although results varied for study behavior verses GPA. In Study 1, an interaction between volitional competency and subjective norm explained unique variation in study behavior controlling for TPB variables and past behavior. In Study 2, implicit attention control had a direct effect on GPA after the TPB variables and past achievement were controlled. Implications for interventions designed to improve tertiary‐level academic achievement are discussed.     

Human papillomavirus vaccination intentions and uptake in college women

Objective: Using the health belief model (HBM) and theory of planned behavior (TPB) as theoretical frameworks, the objectives of this study were: (a) to identify correlates of human papillomavirus (HPV) vaccination intentions and (b) to explore differences between correlates of HPV vaccination intentions and uptake. Methods: Undergraduate women (N = 447) who did not intend to receive (n = 223), intended to receive (n = 102), or had received (n = 122) the HPV vaccine were surveyed. Logistic regressions were conducted to examine the correlates of vaccination intentions and uptake. Results: Negative health consequences of the vaccine, physician's recommendation, positive attitudes toward the vaccine, and subjective norms were significant correlates of vaccination intentions. When comparing correlates of vaccination intentions to correlates of vaccination uptake, physician's recommendation, subjective norms, and perceived susceptibility to HPV were unique correlates of uptake. Conclusion: Differences between correlates of vaccination intentions and uptake suggest that social influences of liked and trusted individuals may make an important and unique contribution in motivating young women to receive the HPV vaccine beyond other variables from the HBM and TPB. Future utilization of longitudinal designs is needed to understand which factors may cause individuals to decide to receive the HPV vaccine.

The Role of Self‐Identity,Past Behavior,and Their Interaction in Predicting Intention to Purchase Fresh and Processed Organic Food1

This study examined the impact of moral norms, self‐identity, and past behavior on intention to buy organic tomatoes and organic tomato sauce, using the theory of planned behavior (TPB). The questionnaire, which included measures of attitudes, subjective norm, perceived behavioral control, moral norms, past behavior, and self‐identity was completed by approximately 500 people for each food. Multiple regressions showed that for both foods, moral norms and self‐identity added significantly to the prediction of intention over and above the other variables, even when the effect of past behavior was included. There was some evidence of past behavior moderating the self‐identity/intention relationship for processed organic tomato sauce, but not for fresh organic tomatoes. Implications of the findings are discussed.     

A test of theory of planned behavior in Korea: participation in alcohol-related social gatherings

Two studies are reported using the theory of planned behavior (TPB) to predict and explain joining and not joining alcohol-related social gatherings among Korean undergraduates in various engineering majors. Specifically, considering that the attitudinal component of TPB is behavioral-outcome-based, the current study investigated whether the outcomes of engaging in a behavior and of not engaging in a behavior would similarly predict intentions to engage in a behavior and intentions to not engage in a behavior. The current study also examined whether intentions to engage and intentions to not engage would be significantly related to self-reported behavior a week later. Participants in Study 1 reported TPB components (attitudes toward behavior, subjective norms, perceived behavioral control, and behavioral intentions) concerning joining alcohol-related social gatherings. Participants in Study 2 reported TPB components concerning not joining alcohol-related social gatherings. Additionally, a week later, the participants in both studies reported their participation in alcohol-related social gatherings from the past week. Generally, the results showed that the TPB components were significantly associated with undergraduates' intentions to join and intentions to not join. Specifically, conversation-related attitudes and senior-junior relationship-related attitudes were significantly related to intentions to join, and only group-related attitudes were significantly related to intentions to not join. Intentions to join and intentions to not join were not significantly related to self-reported behavior of joining alcohol-related social gatherings a week later. The findings from the current research provide some evidence that joining or not joining alcohol-related social gatherings may not be mere behavioral opposites, predictable by the presence or absence of the same behavioral outcomes. These two aspects of the behavior may require assessment of different behavioral outcomes or different assessments of the same behavioral outcomes.     

Extending the Theory of Planned Behavior: A Review and Avenues for Further Research

This paper describes and reviews the theory of planned behavior (TPB). The focus is on evidence supporting the further extension of the TPB in various ways. Empirical and theoretical evidence to support the addition of 6 variables to the TPB is reviewed: belief salience measures, past behavior/habit, perceived behavioral control (PBC) vs. self-efficacy, moral norms, self-identity, and affective beliefs. In each case there appears to be growing empirical evidence to support their addition to the TPB and some understanding of the processes by which they may be related to other TPB variables, intentions, and behavior. Two avenues for expansion of the TPB are presented. First, the possibility of incorporating the TPB into a dual-process model of attitude–behavior relationships is reviewed. Second, the expansion of the TPB to include consideration of the volitional processes determining how goal intentions may lead to goal achievement is discussed.     

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.     

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.     

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.     

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.     

The importance of subjective norms for people who care what others think of them

Using the framework of the Theory of Planned Behaviour (TPB), this study examined whether the extent to which people are concerned with others’ approval of them moderates the subjective norms–intentions relationship in the context of exercise. The participants were 325 undergraduate students who completed a questionnaire assessing the TPB constructs (subjective norms, attitudes, perceived behavioural control, intentions) and the Brief Fear of Negative Evaluation Scale. The results of hierarchical regression analyses indicated that subjective norms were a significant predictor of intentions to exercise only for people highly concerned with receiving disapproval from others (i.e., high fear of negative evaluation) and not for people low on this trait.
