Application of the theory of planned behaviour to the prediction of objectively assessed breaking of posted speed limits

In two studies the Theory of Planned Behaviour (TPB) including moral norms, anticipated regret and past behaviour was applied to predicting intention to exceed the posted speed limit across different roads and objectively assessed speeding behaviour. All measures except behaviour were taken by self‐report questionnaires referring to different driving scenarios. The behaviour measures were based on performance in a simulator (Study 1) or unobtrusive on‐road speed camera assessment taken without driver awareness (Study 2) across roads with varying posted speed limits. Results are reported averaged across road types in both studies. In Study 1 (N = 83), 82% of the variance in intentions to speed was explained, with attitudes, subjective norms, perceived behavioural control (PBC), moral norms, anticipated regret and past behaviour being significant predictors. A total of 35% of the variance in speed as assessed on a driving simulator was accounted for with intentions, PBC, moral norms and previous accidents being significant predictors. In Study 2 (N = 303), 76% of the variance in intentions to speed was explained with attitudes, moral norms, anticipated regret and past behaviour being significant predictors. A total of 17% of the variance in speed as assessed on‐road was accounted for with intentions and moral norms being significant. Practical implications of the findings for road safety are discussed.     

Feel good now or regret it later? The respective roles of affective attitudes and anticipated affective reactions for explaining health‐promoting and health risk behavioral intentions

Evidence supporting the incorporation of affective constructs, such as affective attitudes and anticipated regret, into theoretical models of health behavior has been mounting in recent years; however, the role of positive anticipated affective reactions (e.g., pride) has been largely unexplored. The purpose of the present investigation was to assess how affective attitudes and anticipated affective reactions (both pride and regret for performing a behavior or not) may provide distinct utility for understanding intentions to perform health‐promoting and health risk behaviors over and above cognitive attitudes and other established theoretical constructs from the theory of planned behavior (TPB). Participants (N = 210) were recruited via Amazon’s Mechanical Turk to complete a one‐time online battery assessing TPB and affective constructs. Self‐reported intentions served as the main outcome measure, and hierarchical linear modeling was used to examine the effects of TPB and affective constructs across behaviors. Controlling for TPB constructs, more positive affective attitudes and greater anticipated regret, but not anticipated pride, predicted intentions to engage in future health behaviors. Anticipated affective reactions contributed explanatory variance for intentions to perform health risk behaviors, but anticipated pride and regret were not associated with intentions to perform health risk behaviors. Contributions made via the inclusion of both positively and negatively valence anticipated affective reactions for both action and inaction (performing a behavior or not) across a range of health promoting and health risk behaviors are discussed, as well as implications for future intervention work.     

The effect of self‐identity alongside perceived importance within the theory of planned behaviour

Self‐identity often predicts behavioural intentions after standard theory of planned behaviour (TPB) components are accounted for. However, it has been claimed this is due to conceptual similarity between self‐identity and perceived importance of the behaviour. We examined this claim within the context of recycling food waste. Participants (N = 113) completed questionnaires assessing intentions, attitude, perceived behavioural control, perceived norms, perceived importance, self‐identity, and past behaviour. Confirmatory factor analysis indicated that self‐identity and perceived importance were distinct constructs. Further, after accounting for TPB components and perceived importance, self‐identity explained a significant amount of additional variance in intentions. The present findings therefore do not support this particular argument against the predictive utility of self‐identity.     

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.     

Self-conscious emotions and self-regulation in the promotion of condom use

Two prospective studies examined the self-regulatory role of anticipated negative self-conscious emotions (ANSCE) in the theory of planned behavior. In Study 1, 147 undergraduates reported condom attitudes, perceived norms, self-efficacy, ANSCE (shame and guilt) should they not use condoms, and intentions to use condoms during the coming 6 weeks. At a 6-week follow-up, ANSCE predicted condom use intentions and behavior and partially mediated the effect of attitudes and norms on both. Study 2 experimentally tested the social nature of self-consciousness in ANSCE; 61 female undergraduates read a scenario priming the private-self or social-self or were assigned to a no-scenario control. They reported condom attitudes, perceived control, ANSCE, condom use intentions, and a 6-week follow-up. ANSCE again predicted condom use intentions. A test of moderated mediation indicated that ANSCE influenced condom intentions more in the social-self condition than in the control condition. Implications of these findings are discussed.     

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.     

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.     

Analysing the Influence of Autonomous and Controlling Social Factors Within the Theory of Planned Behaviour

The aim of this study was to analyse the effects of autonomous (i.e., autonomy support from parents and peers) and controlling (i.e., social physique anxiety) social factors on future intention to exercise, integrating the distal (i.e., basic psychological needs satisfaction and self‐determined motivation) and proximal (i.e., attitudes, perceived behavioural control and subjective norms) determinants of intention defined in self‐determination theory (SDT) and the theory of planned behaviour (TPB). Self‐report questionnaires were distributed to 390 secondary school pupils (male = 218, female = 172, M_age = 15.10, standard deviation = 1.94). The results of path analysis, controlling for past behaviour of physical activity, showed that social factors predicted future intention to exercise through the influence of the distal and proximal determinants. The main contribution of the study was to provide evidence that the proximal determinants of the TPB captured the direct influence of social factors, independent of the mediating effects of psychological needs satisfaction and self‐determined motivation towards exercise. Results supported the integration of the two theories, clarifying the processes of influence of autonomous and controlling social factors within the variables of SDT and the TPB.     

Destigmatising the stigma: Understanding the impact of message framing on Chinese consumers' guilt and attitude associated with overspending behaviour

Overspending has been a largely stigmatised consumer behaviour in traditional Chinese culture. However, social and economic development in recent decades has induced the rise of Chinese consumerism and changes in public attitudes towards overspending. Focusing on overspending stigmas Gouwukuang (GWK) and Duoshoudang (DSD) and stigma‐relevant attitudes, the present study investigates the effect of perceived stigma on consumers' attitude towards overspending through the mediating effect of anticipated consumer guilt. The moderating role of message framing in this relationship is also examined. Results of two analyses indicate that (a) between the two stigmas, DSD is less stigmatising and preferred in comparison to GWK in social interaction and self‐identification; (b) participants' perception of the stigma associated with overspending predicts their anticipation of guilt associated with this behaviour, which in turn predicts negative attitude towards overspending; (c) message framing moderates the relationship between perceived stigma and anticipated guilt, and hence facilitates destigmatisation of the traditionally stigmatised behaviour of overspending. Theoretical and practical implications of these findings are discussed.     

Positively versus negatively charged moral emotion expectancies in adolescence: The role of situational context and the developing moral self

The study analyses adolescents' positively charged versus negatively charged moral emotion expectancies. Two hundred and five students (M= 14.83 years, SD= 2.21) participated in an interview depicting various situations in which a moral norm was either regarded or transgressed. Emotion expectancies were assessed for specific emotions (pride, guilt) as well as for overall strength and valence. In addition, self‐importance of moral values was measured by a questionnaire. Results revealed that positively charged emotion expectancies were more pronounced in contexts of prosocial action than in the context of moral transgressions, whereas the opposite was true for negatively charged emotions. At the same time, expectations of guilt and pride were substantially related to the self‐importance of moral values.     

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.     

Pro‐peace or anti‐war: The effect of emotions primed by protest songs on emotions toward in‐group and out‐group in conflict

Members of societies in conflict hold stable positive and negative views, and emotions of the in‐group and out‐group, respectively. Music is a potent tool to express and evoke emotions. It is a social product created within a social and political context, reflecting, and commenting it. Protest songs aim to change views and attitudes toward ongoing conflicts. Their message may be expressed positively (pro‐peace songs) or negatively (anti‐war songs). Previous research has shown that evoking emotions such as guilt toward the in‐group or empathy toward the out‐group may influence attitudes toward reconciliation. The present research, conducted in Israel, presents three studies investigating whether emotions evoked by positive or negative protest songs may influence in‐group members' guilt toward the in‐group (Israeli Jews) and empathy toward the out‐group (Palestinians). Studies 1 and 2 show that negative emotions evoked by negative protests songs predicted both empathy and guilt when the out‐group is considered as a whole (Study 1) or as a particular individual (Study 2). Study 2 in addition showed that empathy predicts an altruistic decision regarding an out‐group member. Emotions evoked by lyrics alone (Study 3) did not contribute to explained variance in either guilt or empathy, nor the altruistic decision. Results suggest that negative emotions expressed by negative protest songs, focused on the in‐group, are more effective in influencing attitudes toward out‐groups. Results are discussed in the context of group emotions in conflict and the role of protest songs in intergroup relations.     

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.
