Moderators of Implicit-Explicit Exercise Cognition Concordance

The Relationship of Self-efficacy and Explicit and Implicit Associations on the Intention-Behavior Gap

BACKGROUND

Recent physical activity research is limited by intention-behavior discordance and is beginning to recognize the importance of automatic processes in exercise. The purpose of the current study was to examine the role of multidimensional exercise self-efficacy (SE), explicit-implicit evaluative discrepancies (EIEDs) for health, and appearance on the intention-behavior gap in exercise.

METHODS

A total of 141 middle-aged inactive participants (mean age = 46.12 [8.17] y) completed measures of intentions, SE, and explicit and implicit evaluations of exercise outcomes. The participants were classified as inclined actors (n = 107) if they successfully started the exercise program and inclined abstainers (n = 35) if they were not successful.

RESULTS

The inclined actors and abstainers did not differ on intentions to exercise; however, the inclined actors had higher coping SE and lower EIEDs for health. In addition, the coping SE (Exp [β] = 1.03) and EIEDs for health (Exp [β] = -0.405) were significant predictors of being an inclined actor.

CONCLUSIONS

The interaction between explicit and implicit processes in regard to health motives for exercise appears to influence the successful enactment of exercise from positive intentions. As most physical activity promotion strategies focus on health as a reason to be active, the role of implicit and explicit evaluations on behavioral decisions to exercise may inform future interventions.

Does the discrepancy between implicit and explicit attitudes moderate the relationships between explicit attitude and (intention to) being physically active?

Background

Explicit attitudes as well as implicit attitudes have been shown to be associated with physical activity (PA). These two types of attitudes can, however, be discrepant towards the same object or behavior. This study investigated whether there is a discrepancy between explicit and implicit attitudes (IED) regarding physical activity (PA), and whether IED moderates the relationship between explicit attitude and PA, and explicit attitude and PA intention.

Methods

At baseline (T0) and one (T1) and three months (T2) thereafter, students’ (N = 340) PA levels, intention, explicit attitudes, further PA determinants, e.g. self-efficacy, were assessed. Implicit attitudes towards PA were assessed by means of a tailored Single-Category Implicit Association task.

Results

IED was present but weak. Multiple hierarchical regressions revealed that IED did not moderate the relationship between explicit attitudes and PA or intention. Yet, IED was negatively associated with T0-PA and T1-PA.

Conclusion

The study revealed the important insight that IED is detrimental for PA. Interventions targeting attitudes to increase PA, should ensure that implicit and explicit attitudes regarding PA are concordant.

Examining implicit cognitions in the evaluation of a community-wide physical activity program

The purpose of this study was to incorporate measures of attentional bias and implicit attitudes in the evaluation of a community-wide physical activity program, UWALK, by examining the relationships among proximal, intermediate, and distal outcomes of the program as outlined in the hierarchy of effects model. UWALK incorporated various communication and marketing strategies via mass media, on- and off-line platforms. Participants (N = 127) reported unprompted then prompted awareness of UWALK followed by measures of attentional bias and implicit attitudes, watched a 30-second UWALK video, then completed a thought listing task and questionnaires measuring instrumental and affective attitudes, leisure time physical activity, and demographics. Results showed that participants with unprompted awareness of UWALK demonstrated attentional bias toward UWALK images, positive implicit attitudes, and greater physical activity participation compared to unaware counterparts. Attentional bias, awareness, and implicit attitudes significantly predicted behavior, accounting for 15.2% of the variance. This study emphasizes the importance of including measures of automatic cognitions during evaluation can further inform the effects of a program. The results also showed that it is problematic to assume that visiting a website indicates a program will be remembered and related cognitions will be affected.

The Relationship of Explicit-Implicit Evaluative Discrepancy to Exercise Dropout in Middle-Aged Adults

Discrepancies between automatically activated associations (i.e., implicit evaluations) and explicit evaluations of motives (measured with a questionnaire) could lead to greater information processing to resolve discrepancies or self-regulatory failures that may affect behavior. This research examined the relationship of health and appearance exercise-related explicit-implicit evaluative discrepancies, the interaction between implicit and explicit evaluations, and the combined value of explicit and implicit evaluations (i.e., the summed scores) to dropout from a yearlong exercise program. Participants (N = 253) completed implicit health and appearance measures and explicit health and appearance motives at baseline, prior to starting the exercise program. The sum of implicit and explicit appearance measures was positively related to weeks in the program, and discrepancy between the implicit and explicit health measures was negatively related to length of time in the program. Implicit exercise evaluations and their relationships to oft-cited motives such as appearance and health may inform exercise dropout.

Automatic Evaluations and Exercising: Systematic Review and Implications for Future Research

The general purpose of this systematic review was to summarize, structure and evaluate the findings on automatic evaluations of exercising. Studies were eligible for inclusion if they reported measuring automatic evaluations of exercising with an implicit measure and assessed some kind of exercise variable. Fourteen nonexperimental and six experimental studies (out of a total N = 1,928) were identified and rated by two independent reviewers. The main study characteristics were extracted and the grade of evidence for each study evaluated. First, results revealed a large heterogeneity in the applied measures to assess automatic evaluations of exercising and the exercise variables. Generally, small to large-sized significant relations between automatic evaluations of exercising and exercise variables were identified in the vast majority of studies. The review offers a systematization of the various examined exercise variables and prompts to differentiate more carefully between actually observed exercise behavior (proximal exercise indicator) and associated physiological or psychological variables (distal exercise indicator). Second, a lack of transparent reported reflections on the differing theoretical basis leading to the use of specific implicit measures was observed. Implicit measures should be applied purposefully, taking into consideration the individual advantages or disadvantages of the measures. Third, 12 studies were rated as providing first-grade evidence (lowest grade of evidence), five represent second-grade and three were rated as third-grade evidence. There is a dramatic lack of experimental studies, which are essential for illustrating the cause-effect relation between automatic evaluations of exercising and exercise and investigating under which conditions automatic evaluations of exercising influence behavior. Conclusions about the necessity of exercise interventions targeted at the alteration of automatic evaluations of exercising should therefore not be drawn too hastily.
