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.     

Beyond cognition: predicting health risk behaviors from instrumental and affective beliefs.

OBJECTIVE: Two studies assessed the relative contribution of affective and instrumental beliefs to the prediction of 2 risk behaviors: driving above the speed limit and smoking. DESIGN: Both studies took the form of large-scale questionnaire surveys (Study 1, N=292; Study 2, N=500) measuring instrumental and affective beliefs and self-reported behavior. In both cases, behavior was also measured objectively. OUTCOME MEASURES: In Study 1, speeding behavior was measured via infrared camera along sections of road with 30 mph, 40 mph, and 60 mph speed limits. Self-reports of speeding in these same contexts represented a 2nd dependent variable. In Study 2, level of smoking was measured via a carbon monoxide monitor, and participants were asked to indicate the number of cigarettes they smoked in a week. RESULTS: In Study 1, positive and negative instrumental and affective beliefs were significant predictors of self-reported speed. The most powerful predictor was negative affective beliefs. Observed speed was predicted by negative affective beliefs only. In Study 2, the significant predictors of self-reported smoking and objective measures of smoking were positive and negative affective beliefs. CONCLUSION: The findings indicate the importance of affective beliefs across 2 health risk behaviors. Implications for social cognition models and interventions are discussed.     

A dual-process model of affective and instrumental attitudes in predicting physical activity

IntroductionA novel dual-process model based upon the affective-reflective theory which distinguishes between affective attitude and instrumental attitude at an explicit and implicit level was used to predict physical activity.MethodUndergraduate students (N = 114) completed a lab-based study at two time-points, spaced two weeks apart. Participants completed self-report measures of the theory of planned behavior constructs, including explicit affective attitude and explicit instrumental attitude. Implicit affective attitude and implicit instrumental attitude were measured using single category implicit association tests.ResultsExplicit affective attitude and perceived behavioral control indirectly predicted physical activity through intention, and explicit affective attitude, implicit affective attitude, and intention predicted physical activity directly with a modest effect size (R² = 0.24).DiscussionFindings suggest explicitly and implicitly held evaluative information are conceptually distinct, and affective evaluations are key in guiding physical activity behavior regardless of whether such evaluations are implicit or consciously accessible.     

A dual process model of affective and instrumental implicit attitude,self-monitoring,and sedentary behavior

IntroductionA dual process model based upon the affect and health behavior framework was used to explain sedentary behavior, where affective and instrumental components of implicit attitude were measured. Extending dual process theory, we assessed the moderating role of self-monitoring on the effects of implicit attitude on behavior.MethodIn Study 1, 148 office workers completed measures of affective and instrumental implicit attitude and self-monitoring at baseline, followed by a measure of sedentary behavior one week later. We then replicated this study in 241 undergraduates, with the addition of measures of the theory of planned behavior at the initial time point to represent conscious pathways to behavior.ResultsIn both studies there was no direct effect of either form of implicit attitude on behavior. However, self-monitoring moderated the effect of affective implicit attitude such that affective implicit attitude was a significant correlate of sedentary behavior only in those low in self-monitoring. In Study 2, sedentary behavior was also associate with intention, and intention was in turn associated with explicit affective attitude, subjective norm, and perceived behavioral control. Self-monitoring was not associated with sedentary behavior, nor did it moderate the intention-behavior relationship.DiscussionFindings suggest sedentary behavior is a largely affect driven behavior. Further, both reasoned and automatic processes contribute to sedentary behavior, but automatic processes only make a significant contribution when individuals are not consistently monitoring their behavior.     

The Importance of Affective Beliefs and Attitudes in the Theory of Planned Behavior: Predicting Intention to Increase Physical Activity1

Standard theory of planned behavior (TPB) questions to elicit salient behavioral beliefs may elicit instrumental consequences of behavior, and overlook affective consequences. Two hundred thirteen English adults (35 to 75 years of age) completed a questionnaire that contained closed measures of TPB constructs, and open‐ended questions that asked not only about advantages and disadvantages, but also what respondents would like or enjoy and dislike or hate about being more physically active. Beliefs elicited by affective questions were associated more strongly with a closed affective attitude scale. Beliefs elicited by instrumental questions were associated more strongly with a closed instrumental attitude scale. Closed measures of the standard TPB variables explained 48% of the variance in intention to increase physical activity, while affective attitude explained an additional 11% of the variance. Applications of the TPB should consider affective and not just instrumental determinants of behavior.     

Using the EZ-diffusion model to score a Single-Category Implicit Association Test of physical activity

ObjectiveThe Single-Category Implicit Association Test (SC-IAT) has been used as a method for assessing automatic evaluations of physical activity, but measurement artifact or consciously-held attitudes could be confounding the outcome scores of these measures. The objective of these two studies was to address these measurement concerns by testing the validity of a novel SC-IAT scoring technique.DesignStudy 1 was a cross-sectional study, and study 2 was a prospective study.MethodIn study 1, undergraduate students (N = 104) completed SC-IATs for physical activity, flowers, and sedentary behavior. In study 2, undergraduate students (N = 91) completed a SC-IAT for physical activity, self-reported affective and instrumental attitudes toward physical activity, physical activity intentions, and wore an accelerometer for two weeks. The EZ-diffusion model was used to decompose the SC-IAT into three process component scores including the information processing efficiency score.ResultsIn study 1, a series of structural equation model comparisons revealed that the information processing score did not share variability across distinct SC-IATs, suggesting it does not represent systematic measurement artifact. In study 2, the information processing efficiency score was shown to be unrelated to self-reported affective and instrumental attitudes toward physical activity, and positively related to physical activity behavior, above and beyond the traditional D-score of the SC-IAT.ConclusionsThe information processing efficiency score is a valid measure of automatic evaluations of physical activity.     

A transdisciplinary model integrating genetic, physiological, and psychological correlates of voluntary exercise.

OBJECTIVE: Physical inactivity contributes to as many as 250,000 premature deaths per year (R. R. Pate et al., 1995). The authors' objective was to test a transdisciplinary model of the ways in which genetic variants, physiological factors, and psychological factors are thought to influence exercise with 64 healthy, regular exercisers. DESIGN: In a within-subjects design, psychological and physiological responses to exercise were compared with responses to a sedentary activity. MAIN OUTCOME MEASURES: The authors measured affective state, perceived exertion, heart rate, and temperature change in response to moderate exercise versus sedentary activity. They also quantified genotypes on a single nucleotide polymorphism in the brain-derived neurotrophic factor (BDNF) gene. RESULTS AND CONCLUSIONS: The data show a relation between increases in positive affective states and acute exercise behavior, as opposed to a sedentary control. The BDNF gene moderated the effect of exercise on mood, heart rate, and perceived exertion. Physiological factors were, in turn, related to mood response, and mood response was a significant correlate of motivation to exercise in the future and of current exercise behavior. The model has potential as a framework for the basic study of the genetic, physiological, and psychological processes involved with voluntary exercise and as a tool for the applied examination of tailored exercise interventions and their efficacy for different subsets of individuals.     

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.     

How do I feel about the behavior? The interplay of affective associations with behaviors and cognitive beliefs as influences on physical activity behavior.

Individuals have affective associations with health behaviors. In other domains such associations have been shown to influence behavior, but affective associations with health behaviors are not included in current health decision-making models. The authors examined whether affective associations with exercise predicted individuals' activity behavior and, if so, how they interfaced with other decision-making constructs to influence behavior. Adult participants (N = 433) reported their current physical activity behavior and affective associations with physical activity. Health belief model and theory of planned behavior constructs were also assessed. More positive affective associations with activity significantly predicted greater activity behavior. Moreover, the influence of the health belief model and theory of planned behavior constructs on activity behavior was mediated through affective associations. Affective associations were shown to play a central role in individuals' activity behavior, both as a mediator of the effects of cognitively based decision-making factors and as an independent predictor of activity behavior. The results suggest the need to include affective influences on behavior in formal models of health decision making and, potentially, to explore affectively based intervention routes to change behaviors.     

A multilevel investigation of antecedents of employee positive affective displays: the roles of customer negative affective displays and employee perceived supervisory support

Much past research on employee positive affective displays have explored their antecedents using a single level of analysis. The present study extends previous research by capturing the complex phenomenon of employee affective displays from a multilevel perspective. We used an event-sampling methodology to address a gap in the literature by examining affective displays at the intra-individual level and inter-individual level. Results based on 67 postal clerks completing 420 transactions in post offices in Taiwan show that customer negative affective displays were negatively correlated with employee positive affective displays. Moreover, employee perceived instrumental supervisory support had a cross-level moderating effect on the within-individual relationship between customer-displayed negative emotions and employee-displayed positive emotions. Specifically, those with perceived higher levels of instrumental supervisory support tended to express friendlier emotions while interacting with unhappy or angry customers than those with perceived lower levels of instrumental supervisory support. At the inter-individual level, results show that employee perceived emotional supervisory support was positively related to their affective displays at the aggregated employee level.     

Changes in implicit and explicit exercise-related attitudes after reading targeted exercise-related information

The purpose of this research was to examine if reading exercise information targeted at pretest explicit attitudes were related to changes in corresponding implicit or explicit attitudes. The associative-propositional evaluation (APE) model guided the research. Participants (N = 154) completed pretest measures of implicit and explicit attitudes; one week later they read information that targeted pretest explicit affective or instrumental attitudes and again completed the attitude measures. Results showed changes in implicit attitudes in both instrumental message conditions that supported the hypotheses that counter-attitudinal information would result in implicit attitude change in the opposite direction to the reading whereas information that targeted congruent attitudes would show changes in keeping with the information. This study demonstrates the importance of considering how implicit cognitions may change as a result of reading exercise-related information, and the relationship between implicit and explicit attitudes.

The Relationship Between Enjoyment and Affective Responses to Exercise

Exercise-related affective changes are well documented across a variety of settings and populations. In addition to the stimulus properties of exercise itself, social environmental factors are thought to influence affective responses. One factor that may be associated with psychological responses to exercise is enjoyment. Individuals who enjoy exercise may exhibit more positive affective responses compared to those who enjoy exercise less. The purpose of this study was to examine whether exercise enjoyment was related to affective changes associated with an acute bout of exercise in a naturalistic setting. Study 1 used a categorical approach to assess affect and sampled college-aged female group fitness participants. Study 2 was based on a dimensional affect conceptualization and sampled corporate fitness participants. Across both studies, results revealed a significant decrease in negative affect and increase in positive affect following exercise. Enjoyment was positively related to increases in positive affect but unrelated to changes in negative affect.     

Gender‐Related Psychological Characteristics and Situational Determinants of Psychophysiological Stress Reactivity1

This study examined the influence of gender‐related psychological characteristics and situational demands on physiological and affective responses to stressful tasks. While physiological and affective responses were monitored, 44 medical students (26 men, 18 women) performed an emotion‐oriented speech task and an action‐oriented speech in a counterbalanced design. Conventionally masculine instrumental and feminine expressive characteristics were measured using the Personal Attributes Questionnaire. Systolic blood pressure and respiratory reactions to the action‐oriented task were positively associated with expressivity. Expressivity was also associated with greater subjective tension during the action‐oriented task, and with perceptions of greater task difficulty. The results are consistent with the notion that physiological and affective stress reactions in men and women are determined in part by traditionally gender‐related psychological characteristics, with greater reactions when the situational demands are not congruent with preferred modes of behavior.     

Affective and health-related outcome expectancies for physical activity in older adults

This study tests the effects of affective and health-related outcome expectancies on physical exercise, assuming stronger direct and indirect (via intention) effects from affective outcome expectancy to physical exercise than from health-related outcome expectancy to exercise. Physical exercise and social cognitive variables were assessed at baseline, and 6- and 12-month follow-up in 335 older adults (60–95 years of age). Applying structural equation modelling, there was a direct effect from affective, but not from health-related outcome expectancy on intentions and behaviour. Also, the indirect effect from self-efficacy on physical exercise via affective outcome expectancy was significant, whereas the mediation via health-related outcome expectancy was not. These findings emphasise the relative importance of affective versus health-related outcome expectancies in predicting intentions and physical exercise in older adults and highlight the importance to separate these facets at a conceptual level to enhance both theory development and health promotion.

Affective and cognitive predictors of affective response to exercise: Examining unique and overlapping variance

ObjectivesAffective response to exercise has been suggested as an important factor in determining regular exercise. However, it is unclear the extent to which anticipatory affect factors (affective attitudes, implicit associations, and affective associations), anticipated affect factors (anticipated regret, anticipated pride), and cognitive factors (self-efficacy, intentions) explain overlapping or unique variance in affective response to exercise.DesignWe systematically examined the extent to which these various affective and cognitive factors relevant to exercise predict affective response, and determined the extent to which these factors account for unique or overlapping variance in affective response.MethodHealthy young adults (N = 69) completed measures of affective attitudes, affective associations, implicit associations, anticipated affect, self-efficacy, and exercise intentions. Participants then exercised for 20-min at moderate intensity on a treadmill, during and after which they reported their affective response. Using variables that were independent predictors, we conducted multivariate analyses to determine which factors account for unique variance in affective response to exercise.ResultsIn three of four multivariate models, both anticipated and anticipatory affect variables explained unique variance in affective response during exercise. Only anticipatory affect variables accounted for unique variance in affective response immediately post-exercise. Finally, the association between exercise self-efficacy and affective response during-exercise was rendered non-significant after controlling for affective factors in all three multivariate models.ConclusionsThe unique associations between affective response to exercise and affective, but not cognitive, factors elucidate key predictors of affective response during- and post-exercise.     

阈上阈下启动刺激在不同锻炼人群中引发自动评价的特点

双加工理论认为锻炼行为形成中自动加工（系统1）和熟虑加工（系统2）是两个相互作用但又截然不同的信息处理系统,其中自动评价通过触发系统1的自动加工过程激活运动记忆自发的心理联想,并对运动进行情感评价,从而影响锻炼行为。本研究的目的是检测锻炼相关刺激在不同锻炼人群中引发的自动评价特点。采用评价启动任务范式,实验1和实验2分别给予阈上和阈下锻炼词或非锻炼词作为启动刺激,之后要求被试对积极或者消极目标词进行按键反应。研究结果显示无论阈上还是阈下呈现锻炼启动词,均表现为锻炼组对积极目标词反应速度更快。结果表明：锻炼人群对于锻炼词具有积极自动评价。
