Examining acute environmental effects on affective state, expectancy, and intention in sport climbing

Abstract

IntroductionPsychological research has shown that, among other variables, affective state, expectancy, and behavioral intention influence whether or not a (physically active) behavior is performed. Environmental effects during physical activity on affective state have been well studied; however, research regarding environmental effects on expectancy or intention is limited. Sport climbing is a form of physical activity that is performed both indoors and outdoors and is therefore considered as suitable to study environmental effects. Therefore, the aim of the present study was to investigate environmental effects during sport climbing on affective state, expectancy, and intention. The nature of the relationship between some of these parameters should also be explored.MethodsUsing a within-subjects design, 48 participants were to climb both once indoors in a climbing gym and once outdoors at a crag. The design included questionnaire-based surveys at multiple time points. Affective state, expectancy, and behavioral intention were measured at different test time points.ResultsTwo-factor repeated-measures ANOVAs revealed significant main effects of the factors environment (indoor – outdoor) and time (T1 – T2 – T3) for affective state, indicating more positive affective state during outdoor climbing. No environment*time interactions were found. Furthermore, significantly higher intention (d = 0.32; p = 0.032) was measured after the outdoor condition (M = 32.5, SD = 4.1) compared to the indoor condition (M = 31.2, SD = 4.7). Multiple linear regressions revealed that expectancies (measured before and after the session) significantly predicted post-climbing intention only indoors.ConclusionThe results at least partly suggest environmental effects on behaviorally relevant variables during climbing. Outdoor climbing might provide more favorable characteristics for physically active behavior compared to indoor climbing. Health psychologists or public health professionals who focus on increasing physical activity for their clients could recommend outdoor climbing over indoor climbing.
