Experimental induction of sad mood states is a mainstay of laboratory research on affect and cognition, mood regulation, and mood disorders. Typically, the success of such mood manipulations is reported as a statistically significant pre- to post-induction change in the self-rated intensity of the target affect. The present commentary was motivated by an unexpected finding in one of our studies concerning the response rate to a well-validated sad mood induction. Using the customary statistical approach, we found a significant mean increase (...) in self-rated sadness intensity with a moderate effect size, verifying the “success” of the mood induction. However, that “success” masked that, between one-fifth and about one-third of our samples reported absolutely no sadness in response to the mood induction procedure. We consider implications of our experience for emotion research by commenting upon the typically overlooked phenomenon of nonresponse, suggesting changes in reporting practices regarding mood induction success, and outlining future directions to help scientists determine why some subjects do not respond to experimental mood induction.

Disordered sleep is strongly linked to future depression, but the reasons for this link are not well understood. This study tested one possibility – that poorer sleep impairs emotion regulation, which over time leads to increased depressive symptoms. Our sample contained individuals with a wide range of depression symptoms, who were followed clinically over six months and reassessed for changes in depressive symptom levels. As predicted, maladaptive ER mediated both cross-sectional and prospective relationships between poor sleep quality and depression symptoms. (...) In contrast, an alternative mediator, physical activity levels, did not mediate the link between sleep quality and depression symptoms. Maladaptive ER may help explain why sleep difficulties contribute to depression symptoms; implications for interventions are discussed. (shrink)

Why do people with psychopathology use less adaptive and more maladaptive strategies for negative emotions if such usage has self-destructive consequences? Although researchers have examined the reasons for people’s engagement in maladaptive “behaviors,” such as nonsuicidal self-injury, surprisingly little attention has been paid to the reasons why people might endorse maladaptive emotion regulation strategies. This article addresses this question, focusing on the case of depression, evaluating an array of 10 possible explanations. After considering the existing evidence, we provide a blueprint (...) to help the field reach stronger conclusions about depression and other forms of psychopathology. Better understanding of the origins of healthy/unhealthy ER has implications for clinical science, clinical practice, as well as their integration. (shrink)
