Successive association of adaptive/maladaptive response styles to depressive mood and decentering: a preliminary study of Japanese university students

Response styles to depressive mood, which are ruminative or distractive responses, have both adaptive and maladaptive forms. The adaptiveness of ruminative/distractive responses is associated with decentering. However, whether decentering increases using adaptive response styles or adaptive (maladaptive) response styles heighten (lower) decentering levels remains unclear. This short-term longitudinal survey examined the sequential influence of decentering on response styles and the indirect effect of decentering on depression through response styles. One hundred twenty-six Japanese undergraduates completed questionnaires on response styles, decentering, and depressive symptoms at two points in time, four weeks apart. Cross-lagged panel analyses indicated that decentering predicted lower maladaptive ruminative and distractive responses and a higher adaptive ruminative response. Adaptive ruminative response predicted higher decentering. Furthermore, mediation analyses showed that decentering influenced depression through adaptive/maladaptive ruminative responses. Results suggest that an individual’s decentering level partly determines which response style is likely to be used when an initial depressive mood is experienced.
