Ruminative self-focus on mood, problems and other aspects of self-experience can have both mal adaptive consequences, perpetuating depression, and, adaptive consequences, promoting recovery from upsetting events. Increasing evidence suggests that these contrasting effects may be explained by distinct varieties of ruminative self-focus, each with distinct functional properties. This study tested the prediction (Emotional processing, three modes of mind and the prevention of relapse in depression. Behav. Res. Therapy, 37 (1999) S53) that an experiential mode of self-focused attention would facilitate recovery from an upsetting event in comparison to a conceptual-evaluative mode of self-focused attention. To test these contrasting effects experimentally, 69 participants wrote about an induced failure experience in either a conceptual-evaluative condition (e.g. "Why did you feel this way?"), or an experiential condition ("How did you feel moment-by-moment?"). Consistent with the hypothesis, higher levels of trait disposition to ruminate were associated with relatively greater increases in negative mood 12 h after the failure in the conceptual-evaluative condition compared to the experiential condition. Furthermore, the conceptual-evaluative condition resulted in more intrusions about the failure than the experiential condition. These results support the differentiation of rumination into distinct modes of self-focused attention with distinct functional effects; a conceptual-evaluative mode that is maladaptive and an experiential mode that is adaptive.
