Can self-compassion improve sleep quality via reduced rumination?

ABSTRACT

Poor sleep quality is highly prevalent in modern societies and can be associated with a multitude of problems for individuals and organizations, and also for society at large. Thus, there is a demand for efficient treatments. We suggest that short self-compassion interventions will improve sleep quality via reducing ruminative thoughts, a key variable associated with poor sleep quality. We ran three studies to test this hypothesis. In Study 1 (correlational data), a positive relationship between self-compassion and sleep quality emerged in students’ self-reports. This effect was mediated by rumination. In Study 2, students in two different self-compassion intervention conditions reported higher sleep quality compared to a control condition. Again, rumination mediated this effect. In Study 3, patients with major depressive disorder reported a significant increase in sleep quality and a significant decrease of ruminative thoughts after one week in a daily self-compassion intervention (compared to patients in a control condition). Limitations and implications for future research, such as the need of placebo control groups, objective sleep quality measures, and person–intervention fit designs are discussed.     

Shaping cooperation behavior: The role of accessibility experiences and uncertainty

The present research investigates the influence on cooperative behavior of accessibility experiences associated with the retrieval of fairness‐relevant information from memory. We argue that the decision whether to cooperate in negotiations depends not only on information about the appropriateness of the negotiation procedure, but also on the experience of how difficult or easy it is to come up with this information. Supporting this hypothesis, it is shown that in the context of a bargaining experiment, participants' experiences of ease or difficulty in retrieving unfair aspects of the respective negotiation procedure strongly influence their cooperation behavior. In addition, we hypothesize and empirically substantiate that the influence of accessibility experiences on cooperation behavior occurs particularly in situations of certainty salience. Implications for future research on cooperation and on accessibility experiences are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

The impact of onlooking and including bystander behaviour on judgments and emotions regarding peer exclusion

We investigated judgments and emotions in contexts of social exclusion that varied as a function of bystander behaviour (N = 173, 12‐ and 16‐year‐olds). Adolescents responded to film vignettes depicting a target excluded by a group with no bystanders, onlooking bystanders, or bystanders who included the target. Adolescents were asked to judge the behaviour and attribute emotions to the excluding group, the excluded target, and the bystanders. Younger adolescents judged the behaviour of the excluding group as more wrong than older adolescents when there were no bystanders present, indicating that the presence of bystanders was viewed as lessening the negative outcome of exclusion by the younger group. Yet, bystanders play a positive role only when they are includers, not when they are silent observers. This distinction was revealed by the findings that adolescents rated the behaviour of onlooking bystanders as more wrong compared with the behaviour of including bystanders. Moreover, all adolescents justified the inclusive behaviour more frequently with empathy than the onlooking behaviour. Adolescents also anticipated more empathy to including bystanders than to onlooking bystanders, as well as anticipated more guilt to onlooking bystanders than including bystanders. The findings are discussed in light of the role of group norms and group processes regarding bystanders' roles in social exclusion peer encounters.
