The coupling of short sleep duration and high sleep need predicts riskier decision making

Abstract

Objective: To examine how risk-related decision making might be associated with habitual sleep variables, including sleep variability, sleep duration and perceived sleep need in young adults cross-sectionally and longitudinally.

Design: 166 participants completed a 7-day protocol with sleep and risk-related decision-making measures at baseline (T1) and 12 months later (T2).

Results: Habitual short sleep duration (averaging < 6?h nightly) was identified in 11.0% in our sample. After controlling for baseline demographic factors and risk-taking measures, self-reported sleep need at T1 interacted with habitual short sleep in predicting risk taking at follow-up (F_8,139=9.575, adjusted R²=.431, p<.001). T1 greater perceived sleep need predicted more risk taking among short sleepers, but decreased risk taking among normal sleepers at T2. Variable sleep timing was cross-sectionally correlated with making more Risky choices at baseline and fewer Safe choices after loss at follow up.

Conclusions: Young adults with variable sleep timing and those with short sleep duration coupled with high perceived sleep need were more likely to take risks. The moderating effects of perceived sleep need suggest that individual differences may alter the impact of sleep loss and hence should be measured and accounted for in future studies.     

Effects of 7.5% CO2-Induced Anxiety on Individual Performance During a Group Computer Combat Game

The inhalation of 7.5% CO₂ has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO₂ gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO₂ compared with air, indicating CO₂-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO₂ inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.     

Book reviews

Current research on medically unexplained somatic symptoms (MUSS) shows a renewed interest in psychodynamic approaches. Patients with MUSS lack the capacity to mentalize about their feelings. They have an attachment history characterized by insecure attachment relationships. They have a personality trait that can be best described as self-critical perfectionism. Their insecure early attachment relations have had a negative impact on the development of their stress regulatory system. Staff of Psychotherapeutisch Dagcentrum, affiliated with the Department of Psychiatry of a general hospital in Tilburg, found dynamic interpersonal therapy (DIT) a suitable treatment model for the treatment program that was run for patients with MUSS. DIT was developed by Lemma, Fonagy, and Target in the UK for the individual treatment of patients suffering from depression. Subsequently, a variant of DIT was developed in order to make it suitable for application in a multidisciplinary group setting.     

Receiving slaps,receiving words. The violence of separation in a public service time limited psychotherapy group for adolescents

The authors propose a reflection on a time-limited psychoanalytic group for children, adolescents and families, run in a public service. Some patients in the group give accounts of violent relationships and traumatic experiences. The accounts of violent, interpersonal and intrapsychic relationships influence the group’s capacity of thinking, which leads to difficulties in the processing of symbolic aspects. The fundamental question is that of whether it is possible to work in a time-limited, institutional, psychoanalytical framework, in which psychotherapists have to attempt to give meaning to experiences which take place in a repetitive present, in a space/time in which the prospect of a conclusion appears to be inconceivable. By means of a clinical example, and with particular emphasis on the first sessions and the dream brought up by a patient who has been a victim of domestic violence, the authors discuss the possibility of modifying, chiefly from within, the feeling of the immutability of early psychic material, which is itself intrinsically violent.     

Countering Correctional Discourse

SUMMARY

This article discusses the development of a feminist support group for women prisoners enrolled in a six-month substance abuse treatment program in an adult correctional facility in Guam. After the completion of five Group cycles, a follow-up study was conducted in the community using qualitative, feminist, and participatory methods. Results indicate that the Group was successful in helping women prisoners to address trauma, addiction, and the stresses associated with incarceration. Nevertheless, participants reported having significant difficulty transitioning into the community upon release and 23% were sent back to prison for parole violations. Recommendations are outlined for gender-responsive programming, both within women's prisons and in the community, to support women offenders after release.

Social Behavioral Goals and Reimbursable Developmental Activity Strategies

This article is designed to assist new practitioners and those returning to activity group work to develop behavioral goals which are reimbursable and socially developmental across five levels of participation. It presents examples of activities appropriate for five levels of social group development. In addition, it provides an example of an activity group protocol directed toward a specific group level. Finally, it includes suggested strategies for activity group leaders in schools, clinics, and hospitals.     

An Occupational Therapist's Interdisciplinary Approach to a Geriatric Psychiatry Activity Group: A Case Study

Occupational therapy has long recognized the usefulness of activity groups to promote functional outcomes for clients in mental-health settings. An occupational therapist used an interdisciplinary approach (working with a psychiatric nurse practitioner and a manual arts therapist) to conduct a biweekly geriatric psychiatry activity group. A case study is presented to demonstrate the success and longevity of the interdisciplinary activity group. Each clinician contributed unique skills to provide occupation which provided positive outcomes for the clients. Practically, the employing of different disciplines allowed group coverage for each other in times of cost-containment and limited resources.     

Post-decision consolidation in large group decision-making

Decision-makers tend to change the psychological attractiveness of decision alternatives in favor of their own preferred alternative after the decision is made. In two experiments, the present research examined whether such decision consolidation occurs also among individual group members in a large group decision-making situation. High-school students were presented with a decision scenario on an important issue in their school. The final decision was made by in-group authority, out-group authority or by majority after a ballot voting. Results showed that individual members of large groups changed the attractiveness of their preferred alternative from a pre- to a post-decision phase, that these consolidation effects increased when decisions were made by in-group members, and when participants identified strongly with their school. Implications of the findings for understanding of group behavior and subgroup relations are discussed.
