Brief mindful yoga intervention fails to prevent depression-related outcomes after a dysphoric affect induction

Abstract

Objectives This study was designed to test whether a brief mindful yoga intervention can prevent depression-related responses to dysphoric events. Methods One-hundred-75 undergraduate participants were assigned to one of four conditions in a single-session study. Three conditions received a dysphoric affect induction. Before the induction, participants completed a 20-minute intervention consisting of (a) mindful yoga, (b) stretching, or (c) relaxation control. The fourth condition consisted of a neutral affect induction to examine the validity of the dysphoric affect induction. We hypothesized that compared to relaxation control and stretching, mindful yoga participants would show less: (H1) state depressed affect; (H2) rumination; and (H3) attentional bias toward depression-related words. Results Validity checks indicated that the dysphoric affect induction led to greater state depressed affect and rumination, but not attentional bias. Compared to relaxation control, mindful yoga did not show less state depression, rumination, or attentional bias. The stretching group showed less depression and rumination. Conclusions The results do not provide support for mindful yoga in preventing depression-related reactivity. It may be that when given in a brief, one-time dose, stretching is the better choice for preventing negative outcomes from a subsequent dysphoric experience.
