Breaking the Habit: On the Highly Habitualized Nature of Meat Consumption and Implementation Intentions as One Effective Way of Reducing It

Reducing meat consumption is an important element of an effective climate protection strategy, but meat consumption is highly habitualized and therefore difficult to change. This article uses an extended version of the theory of planned behavior with habit strength as additional predictor. In one longitudinal (N?=?227) and one prospective correlational study (N?=?212), attitudes toward and perceived ease of meat consumption reduction explained about 60% of variance of meat consumption reduction intentions, with habit strength being the strongest correlate of actual self-reported meat consumption. A third experimental study (N?=?192) demonstrated that implementation intentions can be an effective strategy for realizing reduction aims. We discuss the central role of habits for meat consumption.     

Seat Belt Attitudes, Habits, and Behaviors: An Adaptive Amendment to the Fishbein Model

One hundred thirty-four introductory psychology students participatcd in a longitudinal study of seat belt usage. The model of Fishbein and Ajzen was tested, as was the construct of habit within this context. Multiple regression analyses supported the basic Fishhein and Ajzen model predictions. Attitudes and subjective norms predicted intentions, which in turn predicted behavior. Furthermore, habit predicted behavior better than intention. The following nonspurious relationships were observed in cross-lagged panel correlation tests: influence from subjective norm to intention, influence from intention to attitude, influcnce from attitude to subjective norm, influence from behavior to habit, and, of course, influence from attitude to behavior. Discussion included further consideration of the Fishbein and Ajzen model, social adaptation theory, and implications for seat belt usage.     

Habit as moderator of the intention–physical activity relationship in older adults: a longitudinal study

This longitudinal study examined whether habit strength moderates the intention–physical activity (PA) relationship in older adults, within the framework of the attitude–social influences–efficacy (ASE) model and the theory of planned behaviour (TPB). A total of 1836 older adults (M _age?=?62.95?years, SD _age?=?8.17) completed a questionnaire on social cognitive constructs and PA habit strength at baseline, and six?months later a measure of PA. Three PA habit groups (i.e. low, medium and high) were composed, based on tertiles of the mean index score. Multi-group structural equation modelling analyses showed that intention significantly determined PA behaviour only in participants with a low or medium habit strength towards PA. This result suggests that PA is not intentional at high levels of habit strength and demonstrates the usefulness of incorporating habit in the ASE and TPB models. Results also showed that about half of the participants with a strong PA habit did not meet the recommended PA level. As strong habits may prevent intentional behavioural change and may hinder the receptiveness and openness for informational PA change strategies, additional intervention strategies, such as awareness raising and the use of implementation intentions, are needed for strongly habitual, but insufficiently active older adults.     

Exploring psychological factors of mobile phone use while riding among motorcyclists in Vietnam

Mobile phone use while riding is one of the five most common risky behaviors of motorcycle riders in Vietnam. This study investigated motorcyclist’s mobile phone use while riding intention and behavior based on the extended Theory of Planned Behavior (TPB) framework. Based on this framework, attitude, subjective norm, perceived behavioral control, habits, and health motivation underlying the rider’s mobile phone use while riding intentions and behavior were included in a questionnaire and captured by direct and indirect measurements. Small-displacement motorcycle riders (N = 291) completed the extended TPB based questionnaire. An exploratory factor analysis technique identified the selected factors (e.g., attitude, habit, etc.). Moreover, Structural Equation Modeling results showed moderate to good fits to the observed data. Therefore, the results supported the utilization of extended TPB framework in identifying factors of mobile phone use while riding intention and behavior. Specifically, negative attitude, perceived behavioral control, and mobile phone use while riding habit related to the intention to use a mobile phone while riding of small-displacement motorcyclists. Meanwhile, habit and behavioral intention related to the behavior to use a mobile phone while riding of small-displacement motorcycle riders. Especially, the correlation between behavioral intention and self-reported behavior was very strong. This finding embraced previous research indicating that intention was a major motivational component of behavior. Based on the results, safety intervention implications for small-displacement motorcycle riders were discussed.     

Habit as both a direct cause of intention to use a condom and as a moderator of the attitude-intention and subjective norm-intention relations

Abstract

Undergraduates at an American university were asked questions about their attitudes, subjective norms, habits, and intentions towards using a condom during sexual intercourse. Consistent with previous research (Chan and Fishbein, 1993; Trafimow, 1994), intentions were well predicted by attitudes and subjective norms (r = 0.88 and r = 0.73, p < 0.01 in both cases). Intentions were also well predicted by habits (r = 0.77, p < 0.01). More interestingly, however, for participants who were in the habit of using condoms, attitudes and subjective norms were not significant predictors of intentions to use condoms in the future (r = 0.18 and r = 0.10, p<0.1 in both cases). In contrast, attitudes and subjective norms were strong predictors for participants who were not in the habit of using condoms (r = 0.81 and r = 0.61, p < 0.01 in both cases). These findings were replicated in a second study.     

From intentions via planning and behavior to physical exercise habits

ObjectivesIndividuals who enact a health behavior effortlessly with minimal conscious deliberation can be assumed to have formed a healthy habit. This can be reflected by increases in self-reported habit strength of a behavior. We examined whether physical exercise intentions facilitate changes in exercise habit strength by increasing the use of action planning and exercise.DesignTwo field studies investigated the effect of behavioral intentions on changes in habit strength through a sequential path from action planning to exercise.MethodExercise intentions, action planning, habit strength, and exercise were assessed at two measurement points in time in 231 university students (Study 1), and at four points in time in 134 rehabilitation patients (Study 2).ResultsIn multiple-step mediation models in both samples, there were indirect effects of intentions on habit strength through action planning and behavior.ConclusionAction planning and behavior operated as sequential mediators to bridge the gap between intentions and habit strength. Exercise habit strength may increase as a result of conscious action planning and frequent behavior enactment. Including these constructs jointly into behavior change models may improve the understanding of the mechanisms involved in behavior maintenance.     

Does habit weaken the relationship between intention and behaviour? Revisiting the habit‐intention interaction hypothesis

Habitual behaviours are elicited when a familiar context activates cue‐behaviour associations that have been learned through previous performance. A core hypothesis within habit theory is that, by virtue of its automaticity, habit weakens the impact of intention on action, such that in facilitating conditions, action will be guided more by habit than momentary intentions. This has led to recommendations that habit formation be harnessed as a mechanism for sustaining desirable behaviour over time, when people would otherwise relapse due to loss of motivation. This article reviews theory and evidence around the hypothesized interaction between habit and intention as determinants of behaviour. We first qualify the hypothesis by clarifying that it pertains only to determinants of the instigation of action, rather than execution. Next, drawing on a systematic review of 52 behaviour‐prediction studies, we highlight mixed empirical support for the interaction. We argue that ostensibly inconsistent findings can be reconciled by recognizing the distinction between the direction and strength of intention, and identifying the “facilitating conditions” that may determine the relative influence of habit and intention on behaviour. Evidence demonstrates that when self‐control is diminished, people act habitually regardless of intention direction or strength. When people possess self‐control, habits can help people to act on favourable but weakened intentions, but intentions that oppose habitual tendencies can override habitual influence. This has important implications for behaviour change: even if habit has formed, a minimal level of favourable conscious motivation may be required to sustain behaviours over time. Social psychology might fruitfully move beyond asking whether habit moderates the intention‐behaviour relationship, and instead probe how and in which conditions habits and intentions interact.     

The Importance of Risk in Determining the Extent to Which Attitudes Affect Intentions to Wear Seat Belts1

Stasson and Fishbein (1990) reported findings indicating that college students' intentions to wear seat belts in low-risk situations were attitudinally controlled, while their intentions to wear seat belts in high-risk situations were normatively controlled. If these findings are valid, manipulations of attitude (toward wearing a seat belt) should have a greater impact on intentions to wear a seat belt in a safe situation than on intentions to wear a seat belt in a risky situation. Three experiments provided strong support for this hypothesis. The implications of these findings for defining behavior and for designing interventions to increase seat-belt use are discussed.     

Negotiating safer sex: A detailed analysis of attitude functions,anticipated emotions,relationship status and gender

Objective : Because interpersonal discussion about condom use can encourage subsequent condom use, this project aims to examine the psychological antecedents of intentions to discuss or request the use of condoms with a sexual partner.

Method : The data were collected from 849 heterosexual college students in the USA through an online survey. The survey contained several measures related to attitude functions (i.e. motivations), efficacy, norms and intentions to discuss condom use with a sexual partner.

Results : Participants’ attitude functions weakly predicted intentions to discuss condom use. Communication efficacy was a more important predictor of intentions for females (vs. males) and for those in other relationships or not in a relationship (vs. long-term monogamous relationships). Anticipated negative emotions were a stronger predictor of intentions for those in long-term monogamous relationships (vs. other relationships or not in a relationship).

Implications : Future research needs to consider more detailed attitude functions and anticipated emotions. Furthermore, background variables (e.g. gender and relationship status) can be moderators in addition to being distal predictors.     

The role of work habits in the motivation of food safety behaviors

The authors considered work habits within an integrated framework of motivated behavior. A distinction made between automatic and controlled action led to 2 measures of work habits: a habit strength measure reflecting the 4 characteristics of automaticity and a measure of work routines under conscious control. Workers at a turkey processing plant (N = 162) responded to an extensive survey of these work habits measures with regard to food safety. Results indicated that attitudes and subjective norms predicted food safety intentions. These intentions, along with perceived behavior control and work habits, predicted reports of food safety behaviors. A mediation analysis indicated that the work routines measure accounted for the variance in self-reported behavior and mediated any effect of the habit strength measure.     

Predictors of Young People's Charitable Intentions to Donate Money: An Extended Theory of Planned Behavior Perspective

An extended theory of planned behavior (TPB) was used to predict young people's intentions to donate money to charities in the future. Students (N = 210; 18–24 years) completed a questionnaire assessing their attitude, subjective norm, perceived behavioral control (PBC), moral obligation, past behavior, and intentions toward donating money. Regression analyses revealed that the extended TPB explained 61% of the variance in intentions to donate money. Attitude, PBC, moral norm, and past behavior predicted intentions, representing future targets for charitable‐giving interventions.     

Predicting the Use of Complementary Medicine: A Test of the Theories of Reasoned Action and Planned Behavior1

The present study employed the theory of reasoned action (TRA) and its extension, the theory of planned behavior (TPB), to investigate the factors underlying intentions and actual use of homeopathy over a 1‐month period. The study was prospective in design; 349 respondents completed a TPB questionnaire during the first phase of data collection, and 139 respondents were contacted (by telephone) in Phase 2 to provide information regarding their use of homeopathy. The findings provided support for the TPB as a predictor of intentions and use of homeopathy, and demonstrated that the model significantly enhanced the predictive utility of the TRA. Attitudes, subjective norms, and perceived control emerged as significant predictors of intention (R²= .49), while intention predicted behavior (R²= .56). In addition, past behavior significantly contributed to the prediction of intention and behavior.     

Closing the intention–behaviour gap for sunscreen use and sun protection behaviours

Objective

Two studies were conducted with the aim of closing the intention–behaviour gap for sunscreen use and sun protection behaviours by examining the influence of self-regulatory capacity on the prediction of sunscreen use (Study 1) and self-regulatory capacity and habit on sun protection behaviours (Study 2).

Design

Studies were conducted online. Participants completed questionnaires and cognitive measures and then reported behaviour one week later.

Main Outcome Measures

Questionnaires measuring intention and cognitive tasks measuring self-regulatory capacity were administered to 209 university students. One week later, participants reported behaviour. In Study 2, questionnaires measuring intentions, and habit and cognitive tasks measuring self-regulatory capacity were administered to 178 university students who reported behaviour one week later.

Results

Intention accounted for 7.1% of variance in sunscreen use, no measures of self-regulation accounted for variance in behaviour or moderated the intention–behaviour gap (Study 1). Intention, self-regulatory capacity and habit accounted for 56.1% of variance in sun protection behaviours (Study 2). Intention, self-regulatory ability and habit predicted behaviour, while habit moderated the intention–behaviour gap.

Conclusion

Interventions aimed at increasing sun protection behaviours should take into account level of intention, self-regulatory capacity and habit. Individuals may benefit from habit formation strategies and self-regulation training.     

When planning is not enough: Fighting unhealthy snacking habits by mental contrasting with implementation intentions (MCII)

In two experiments a self‐regulatory strategy combining mental contrasting with the formation of implementation intentions (MCII) was tested for its effectiveness in diminishing unhealthy snacking habits. Study 1 (N = 51) showed that participants in the MCII condition consumed fewer unhealthy snacks than participants in a control condition who thought about and listed healthy options for snacks. In Study 2 (N = 59) MCII was more effective than mental contrasting or formulating implementation intentions alone and mental contrasting was found to increase perceived clarity about critical cues for unhealthy snacking. Together, these findings suggest that MCII is an effective strategy for fighting habits and that one of the underlying processes making MCII superior to implementation intentions alone may be that mental contrasting produces clarity about the critical cues for the unwanted habitual behavior.

习惯研究的现状与展望

习惯是一种由某特定线索引发并指向某特定目标(包括外显目标与内隐目标)的自动化反应。它具有过去有行为的重复、环境线索的稳定与自动化的反应等特征。关于习惯的测量方式主要采取自我报告法（如自我报告过去行为频率、自我报告习惯频率、自我报告习惯索引等）和反应频率测量法。对习惯的形成的理论解释主要有环境促进、态度促进、目标促进等几种观点。未来研究应继续深入探讨习惯的本质、整合形成机制的相关理论及开发更可靠方便的测量工具。     

Changing circumstances, disrupting habits

The present research investigated the mechanisms guiding habitual behavior, specifically, the stimulus cues that trigger habit performance. When usual contexts for performance change, habits cannot be cued by recurring stimuli, and performance should be disrupted. Thus, the exercising, newspaper reading, and TV watching habits of students transferring to a new university were found to survive the transfer only when aspects of the performance context did not change (e.g., participants continued to read the paper with others). In some cases, the disruption in habits also placed behavior under intentional control so that participants acted on their current intentions. Changes in circumstances also affected the favorability of intentions, but changes in intentions alone could not explain the disruption of habits. Furthermore, regardless of whether contexts changed, nonhabitual behavior was guided by intentions.     

Predicting sleep hygiene: a reasoned action approach

Poor and insufficient sleep causes physical, cognitive, emotional, and social impairments. Unfortunately, little is known about the social‐cognitive predictors of daily sleep habits. The current study examined if sleep hygiene could be predicted using the Reasoned Action Model (Fishbein & Ajzen, 2010 ). Across four studies, the model performed well for the prediction of intentions (R²s = .63–.75), and also significantly predicted both self‐reported (R² = .15) and actigraphy‐recorded sleep duration (R² = .11). The results from these studies support the further use of the model toward the goal of designing effective sleep hygiene interventions.     

Noncompliance with Persuasive Appeals for a Prosocial,Altruistic Act: Blood Donating1

Effects of persuasive messages, responsibility denial (RD), and attitude-accessing on blood-giving attitudes, intentions, moral obligations, and behavior were examined. In Study 1, participants (n= 84) who heard a message emphasizing moral reasons for donating indicated a more favorable postmessage attitude and stronger moral obligation to donate than participants exposed to a message aimed at reducing fear, a combined moral and fear- reduction message, or no message. Combined message participants showed greatest intent to donate, yet only 14% of all participants attended a campus drive. In Study 2, low (n= 52) and high (n= 60) RD individuals heard the message arguments and were asked to access their attitudes. Low compared to high RD individuals stated a stronger sense of moral obligation, particularly when they accessed their thoughts relevant to blood donating, and behavioral intention, especially in the combined message condition. Few participants attended a blood drive (12.5%), yet most were low RD individuals from the nonaccessed attitude condition (83%). Results suggest that few individuals will engage in the altruistic act of blood donating, despite the experimental use of persuasive messages and accessing issue-relevant attitudes.
