  • How we are misinterpreting physical activity intention – behavior relations and what to do about it
    The international journal of behavioral nutrition and physical activity, 2019
    Co-Authors: Amanda L. Rebar, Ryan E. Rhodes, Benjamin Gardner
    Abstract:

    Studies of the physical activity Intention-Behavior Gap, and factors that may moderate the Gap (e.g., habit, perceived behavioral control), can inform physical activity promotion efforts. Yet, these studies typically apply linear modeling procedures, and so conclusions rely on linearity and homoscedasticity assumptions, which may not hold. We modelled and plotted physical activity Intention-Behavior associations and the moderation effects of habit using simulated data based on (a) normal distributions with no shared variance, (b) correlated parameters with normal distribution, and (c) realistically correlated and non-normally distributed parameters. In the uncorrelated and correlated normal distribution datasets, no violations were unmet, and the moderation effects applied across the entire data range. However, because in the realistic dataset, few people who engaged in physical activity behavior had low intention scores, the Intention-Behavior association was non-linear, resulting in inflated linear moderation estimations of habit. This finding was replicated when tested with Intention-Behavior moderation of perceived behavioral control. Comparisons of the three scenarios illustrated how an identical correlation coefficient may mask different types of Intention-Behavior association and moderation effects. These findings highlight the risk of misinterpreting tests of the Intention-Behavior Gap and its moderators for physical activity due to unfounded statistical assumptions. The previously well-documented moderating effects of habit, whereby the impact of intention on behavior weakens as habit strength increases, may be based on statistical byproducts of unmet model assumptions.

  • Understanding strength exercise intentions and behavior in hematologic cancer survivors: an analysis of the Intention-Behavior Gap
    Journal of Cancer Survivorship, 2016
    Co-Authors: James R. Vallerand, Ryan E. Rhodes, Gordon J. Walker, Kerry S. Courneya
    Abstract:

    Background Strength exercise improves many health outcomes in cancer survivors but the prevalence and correlates of strength exercise have not been well-described. Moreover, no study has examined the critical Intention-Behavior Gap for exercise in cancer survivors. Purpose The aims of this study are to quantify the Intention-Behavior Gap for strength exercise in hematologic cancer survivors (HCS) and examine correlates of both intention formation and translation using the multi-process action control framework (M-PAC). Methods A random sample of 2100 HCS in Alberta, Canada, were mailed a survey assessing strength exercise behavior, the M-PAC, and demographic/medical variables. Separate logistic regressions were used to analyze the relationships between the correlates and intention formation and translation. Results Surveys were completed by 606 HCS with 58 % ( n  = 353) intending to do strength exercise. HCS who were not retired (OR = 1.56, p  = 0.001), were highly educated (OR = 1.32, p  = 0.001), and had a favorable attitude (OR = 1.56, p  

  • Understanding action control of daily walking behavior among dog owners: a community survey
    BMC public health, 2016
    Co-Authors: Ryan E. Rhodes, Clarise Lim
    Abstract:

    Background Walking among dog owners may be a means to achieve health benefits, yet almost half of owners (approximately 30% of households) are not regularly walking their dogs. Current research on the correlates of dog walking has generally considered intention as the primary determinant of behavior, yet the Intention-Behavior relationship is modest. The purpose of this paper was to apply a framework designed to evaluate the Intention-Behavior Gap, known as multi-process action control (M-PAC), to understand daily walking among dog owners.

  • Explaining the Aerobic Exercise Intention-Behavior Gap in Cancer Survivors.
    American journal of health behavior, 2016
    Co-Authors: James R. Vallerand, Ryan E. Rhodes, Gordon J. Walker, Kerry S. Courneya
    Abstract:

    OBJECTIVES We sought to quantify the aerobic exercise Intention-Behavior Gap in hematologic cancer survivors (HCS), and examine the correlates of intention formation and translation using the multi-process action control framework. METHODS HCS (N = 606) completed a survey reporting their aerobic exercise motivation and behavior. The correlates of intention formation and translation were analyzed using separate logistic regressions. RESULTS Overall, 71% (N = 428/606) of HCS intended to do aerobic exercise, 44% (N = 267/606) met aerobic exercise guidelines, and 60% of intenders (N = 256/428) translated their intention into aerobic exercise. Attitude (OR = 1.9), perceived control (OR = 1.5), younger age (OR = 2.0), and higher education (OR = 2.1) explained intention formation (all ps ≤ .001). A sense of obligation/regret (OR = 2.8), self-regulation over alternative activities (OR = 1.6), attitude (OR = 2.0), perceived control (OR = 1.7), planning (OR = 1.7), being female (OR = 2.0), and younger (OR = 3.0) explained intention translation (all ps < .005). CONCLUSIONS Forming an intention is insufficient for many HCS to meet aerobic exercise guidelines. Interventions targeting the determinants of both intention formation and translation may be most effective in promoting aerobic exercise in cancer survivors.

  • Magnitude and correlates of the Intention-Behavior Gap in hematologic cancer survivors: An application of the multi-process action control framework
    2015
    Co-Authors: James R. Vallerand, Ryan E. Rhodes, Gordon J. Walker, Kerry S. Courneya
    Abstract:

    Background: Efforts to help cancer survivors meet recommended aerobic exercise guidelines report modest success, perhaps because many theory-based interventions focus on intention formation. Only about half of survivors intending to meet exercise guidelines translate their intentions into guideline adherence. Thus, understanding the determinants of both intention formation and translation is important. The multi-process action control (M-PAC) framework proposes that the theory of planned behavior explains intention formation but additional regulatory behaviors (planning, regulation of alternatives), and reflexive factors (sense of obligation, regret, investment) are needed to translate intentions into behavior. Purpose: To explore the determinants of aerobic exercise intention formation and translation in hematologic cancer survivors. Methods: Hematologic cancer survivors (N=606) completed surveys reporting their aerobic exercise motivation and participation. The determinants of intention formation and translation were analyzed using separate logistic regressions. Results: Overall, 71% of participants (n=428) intended to exercise, and 60% of intenders (n=256) met exercise guidelines. The independent correlates of intention formation (all ps

  • The Intention–Behavior Gap
    Social and Personality Psychology Compass, 2016
    Co-Authors: Paschal Sheeran, Thomas L. Webb
    Abstract:

    Bitter personal experience and meta-analysis converge on the conclusion that people do not always do the things that they intend to do. This paper synthesizes research on intention–behavior relations to address questions such as: How big is the intention–behavior Gap? When are intentions more or less likely to get translated into action? What kinds of problems prevent people from realizing their intentions? And what strategies show promise in closing the intention–behavior Gap and helping people do the things that they intend to do?

  • When Intentions Go Public Does Social Reality Widen the Intention-Behavior Gap?
    Psychological science, 2009
    Co-Authors: Peter M. Gollwitzer, Paschal Sheeran, Verena Michalski, Andrea E. Seifert
    Abstract:

    Based on Lewinian goal theory in general and self-completion theory in particular, four experiments examined the implications of other people taking notice of one's identity-related behavioral intentions (e.g., the intention to read law periodicals regularly to reach the identity goal of becoming a lawyer). Identity-related behavioral intentions that had been noticed by other people were translated into action less intensively than those that had been ignored (Studies 1-3). This effect was evident in the field (persistent striving over 1 week's time; Study 1) and in the laboratory (jumping on opportunities to act; Studies 2 and 3), and it held among participants with strong but not weak commitment to the identity goal (Study 3). Study 4 showed, in addition, that when other people take notice of an individual's identity-related behavioral intention, this gives the individual a premature sense of possessing the aspired-to identity.

  • Does State Versus Action Orientation Moderate the Intention-Behavior Relationship?
    Journal of Applied Social Psychology, 2003
    Co-Authors: Paul Norman, Paschal Sheeran, Sheina Orbell
    Abstract:

    According to Kuhl's (1985) theory of action control, action-oriented individuals should be more likely to translate their intentions into action than state-oriented individuals. The present study considered the moderating role of state vs. action orientation on Intention-Behavior relations across 30 behaviors. Respondents (N = 211) completed questionnaires assessing their intentions to perform each of the 30 behaviors and state vs. action orientation. Two weeks later, respondents completed a second questionnaire to assess performance of the 30 behaviors. Between-subjects and within-subjects analyses both failed to provide support for the moderating role of state vs. action orientation, although a more detailed analysis revealed that state-oriented individuals were more likely to act on their intentions in the case of behaviors that were under normative control. The results are discussed in relation to Kuhl's theory of action control and the need to focus on a range of volitional processes when addressing the Intention-Behavior Gap.

  • European Review of Social Psychology, Volume 12 - Intention–Behavior Relations: A Conceptual and Empirical Review
    European Review of Social Psychology, 2002
    Co-Authors: Paschal Sheeran
    Abstract:

    This chapter addresses two questions; how big is the “Gap” between intentions and behavior, and what psychological variables might be able to “bridge” the intention–behavior Gap? A meta-analysis of meta-analyses is used to quantify the Gap and a conceptual analysis of intention–behavior discrepancies is presented. Research is described on the extent to which four groups of variables—behavior type, intention type, properties of intention, and cognitive and personality variables—moderate intention–behavior relations. Finally, the scope of the intention construct is discussed in the light of recent evidence concerning the role of habits and automaticity in human behavior.
