Research has consistently shown that regular physical activity may protect against the development and maintenance of depression and anxiety, whereas sedentary behavior may exacerbate depression and anxiety. However, much of the past research in this area has focused on non-clinical populations. Therefore, the goal of this study was to examine the relations of physical activity and sedentary behavior to depression and anxiety symptom severity among an understudied patient population, patients in residential substance use disorder (SUD) treatment. This study also sought to determine the extent to which physical activity and sedentary behavior relate to depression and anxiety symptom severity above and beyond an established transdiagnostic risk factor for depression and anxiety, emotion dysregulation. A sample of 41 patients from a residential SUD treatment facility completed a variety of self-report measures focused on physical activity, sedentary behavior, emotion dysregulation, and depression and anxiety symptom severity. Physical activity, but not sedentary behavior, was found to significantly predict depression symptom severity above and beyond emotion dysregulation. Physical activity and sedentary behavior did not significantly predict anxiety symptom severity above and beyond emotion dysregulation. In addition to providing additional support for the relevance of emotion dysregulation to depression and anxiety symptom severity, results suggest that physical activity may be another factor to consider in evaluating risk for depression among patients with SUDs. Although additional research in this area is warranted, results also suggest the potential utility of targeting physical activity in reducing risk for depression among patients with SUDs.

Introduction

Increasing attention has been paid toward both the benefits of regular physical activity and the disadvantages of sedentary behavior for mental health. Research has generally shown that moderate to high levels of physical activity are associated with lower levels of depression, whereas no physical activity and sedentary behavior may exacerbate depression (Dunn, Trivedi, & O’Neal, 2001; Martinsen, 2008; Ströhle, 2009; Teychenne, Ball, & Salmon, 2008). Although the cross-sectional nature of most of the studies in this area precludes determination of the temporal direction of this relation, a recent review of studies examining the prospective relation between physical activity and depression (see Mammen & Faulkner, 2013) provided evidence that physical activity may prevent future depression (although not all studies included in this review demonstrated such a relation). Whereas similar findings have also been obtained for anxiety (e.g., Petruzzello, Landers, Hatfield, Kubitz, & Salazar, 1991), less research has been conducted on the relation of physical activity to anxiety and, thus, conclusions regarding a dose-response relation between physical activity and anxiety severity are premature (Dunn et al., 2001; Ströhle, 2009). Research indicates that the relations between physical activity and sedentary behavior and depression and anxiety are found within both clinical and nonclinical populations. For example, the relation between physical activity and depression has been studied among inpatient military veterans (Davidson, Babson, Bonn-Miller, Souter, & Vannoy, 2013) and inpatients and outpatients with mood and anxiety disorders (Harris, Cronkite, & Moos, 2006; Martinsen, Hoffart, & Solberg, 1989; Sexton, Maere, & Dahl, 1989). Yet, the majority of the research in this area has focused on non-clinical populations (Teychenne et al., 2008). Consequently, there is a need to examine these relations within clinical populations at particularly high risk for the experience of depression and anxiety, such as individuals with substance use disorders (SUD).
