Abstract
Repetitive negative thinking (RNT) is a maladaptive response to sadness and a transdiagnostic risk-factor. A critical challenge hampering attempts to promote more adaptive responses to sadness is that the between-person characteristics associated with the tendency for RNT remain uncharacterized. From the perspective of the impaired disengagement hypothesis, we examine between-person differences in blood-oxygen-level-dependent (BOLD) functional networks underlying cognitive conflict signaling, self-referential thought, and cognitive flexibility, and the association between sadness and RNT in daily life. We pair functional magnetic resonance imaging with ambulatory assessments deployed 10 times per day over 4 consecutive days measuring momentary sadness and RNT from 58 participants (40 female, mean age = 36.69 years; 29 remitted from a lifetime episode of Major Depression) in a multilevel model. We show that RNT increases following sadness for participants with higher than average between-network connectivity of the default mode network and the fronto-parietal network. We also show that RNT increases following increases in sadness for participants with lower than average between-network connectivity of the fronto-parietal network and the salience network. We also find that flexibility of the salience network's pattern of connections with brain regions is protective against increases in RNT following sadness. Our findings highlight the importance of functional brain networks implicated in cognitive conflict signaling, self-referential thought, and cognitive flexibility for understanding maladaptive responses to sadness in daily life and provide support for the impaired disengagement hypothesis of RNT.

Abstract
OBJECTIVE Little is known about predictive effects of quality of life aspects on the course of depressive symptoms in clinical and non-clinical settings. This study examines longitudinal associations between depressive symptoms and subjective quality of life (QOL) dimensions using a parallel sample of depressed patients and community controls. METHOD Eighty-two depressed patients were investigated 1, 6, and 42 months after hospital discharge together with 76 community controls regarding depressive symptoms measured by Montgomery Asberg Depression Rating Scale (MADRS) and QOL (WHOQOL-BREF). Data analysis included time-lagged linear models. RESULTS Physical, psychological, environmental and overall QOL, controlled for depressive symptoms, predicted future depression levels. Group status did not moderate these associations. Depressive symptoms predicted future QOL levels only regarding social relations. CONCLUSION Our study suggests that subjective QOL domains have prognostic value for the course of depressive symptoms over time, both in patient and community samples. Respective self-perceptions should therefore be directly addressed by therapeutic and preventive interventions.

Abstract
BACKGROUND Although aggravating effects of rumination on dysfunctional cognitions and endocrine stress responses have been proposed, experimental studies testing these assumptions are lacking. In parallel, mindfulness theory suggests beneficial effects of mindfulness on dysfunctional cognitions. This study aimed to investigate the effects of induced rumination, distraction and mindful self-focus on mood and dysfunctional attitudes and to assess the possible impact of induced rumination on participants' cortisol responses. METHOD Sixty university students were subjected to negative mood induction and subsequently randomly assigned to a rumination, distraction or mindful self-focus condition. The latter included statements focusing on self-acceptance and awareness of the breath. Four saliva cortisol samples were selected during the session. RESULTS Compared to induced rumination, distraction showed a clear beneficial effect on the course of dysphoric mood, whereas a mindful self-focus did not. In contrast to distraction and mindful self-focus, participants induced to ruminate showed significant increases in dysfunctional attitudes from baseline to post-induction. Although rumination was not itself linked to higher cortisol responses, participants scoring high on the Beck Depression Inventory (BDI)-II who were induced to ruminate showed a smaller decrease in cortisol levels than those scoring low on the BDI-II. CONCLUSIONS This study indicates that rumination as a dysfunctional mode of cognitive processing is able to maintain depression-linked dysfunctional thought content. Furthermore, our study revealed preliminary indications for a link between induced rumination and the cortisol stress response in vulnerable individuals.
