The Use of Acceptance and Commitment Therapy to Promote Mental Health and School Engagement in University Students: A Multisite Randomized Controlled Trial

The aim of this multisite randomized controlled trial was to determine whether an intervention based on Acceptance and Commitment Therapy (ACT) was efficacious in improving university students’ psychological flexibility, mental health, and school engagement. Students were recruited in four Canadian universities and randomly assigned to an intervention (n = 72) or a wait-list control group (n = 72). Students in the intervention group took part in four 2.5-hour workshops during a 4-week period and were asked to do exercises at home (e.g., meditation, observation grids). Wait-list students received the intervention soon after the post measurements. MANCOVAs and ANCOVAs revealed that students in the intervention group showed greater psychological flexibility at postintervention than those in the control group. They also reported greater well-being and school engagement, and lower stress, anxiety, and depression symptoms. Taken together, results of this study suggest that an ACT-based intervention offers a valuable way to promote mental health and school engagement in postsecondary settings.     

On the Costs of Nonclassical Logic

Solutions to semantic paradoxes often involve restrictions of classical logic for semantic vocabulary. In the paper we investigate the costs of these restrictions in a model case. In particular, we fix two systems of truth capturing the same conception of truth: (a variant) of the system KF of Feferman (The Journal of Symbolic Logic, 56, 1–49, 1991) formulated in classical logic, and (a variant of) the system PKF of Halbach and Horsten (The Journal of Symbolic Logic, 71, 677–712, 2006), formulated in basic De Morgan logic. The classical system is known to be much stronger than the nonclassical one. We assess the reasons for this asymmetry by showing that the truth theoretic principles of PKF cannot be blamed: PKF with induction restricted to non-semantic vocabulary coincides in fact with what the restricted version of KF proves true.     

In the Wake of Violence: Enacting and Witnessing Hope Among People

In the territory of violence and despair, hope is rare. Recent work on hope has shifted attention from hope as a feeling to hope as a practice that people can do together. This case report of a family exposed to domestic violence highlights the role played by a South African police officer in the mother's actions to separate from the context of violence. As a witness to the violence, the police officer acted from an ethic of justice and an ethic of compassion. Outsider witnessing of a counseling session resulted in the recruiting of a community of acknowledgement for the mother, the police officer, and an Assistant Commissioner of Police. Listening carefully and doing hope together gave rise to alliances against practices of violence. As a step of accountability, the authors used reflexive practices to question their responses and to avoid colonizing practices.     

Emotionally Focused Family Therapy and Play Therapy Techniques

Emotionally Focused Family Therapy provides a framework for understanding children's behaviors in terms of attachment needs of comfort and support. However, when working with young children, play therapy is often developmentally preferred over “talk therapy.” By integrating play therapy techniques within an Emotionally Focused Family Therapy theoretical framework, therapists can help parents understand and meet their child's needs for affection and comfort. This article will discuss how play therapy techniques can be integrated with an Emotionally Focused Family Therapy theoretical framework for work with young children and their families.     

The Motivational Roots of Norms for Environmentally Responsible Behavior

We assessed whether people use a magnitude-matching principle in determining causes for complex social events. We hypothesized that individuals tend to favor causal explanations that match the event in terms of size and scope. In Experiment 1, the magnitude of the consequences of events was manipulated, and participants were presented with two potential causes of modest magnitude and two potential causes of high magnitude. Analyses revealed a relative magnitude-matching effect such that participants were more likely to select high magnitude causes for large magnitude events than modest magnitude events and more likely to select modest magnitude causes for modest magnitude events than large magnitude events. Experiment 2 replicated the magnitude-matching effect with a different event and set of causes, and demonstrated that this effect could be reversed by undermining participants' beliefs in the magnitude-matching principle.     

Etude des Facteurs psychosociaux,du burnout,de la Vigueur et des troubles musculosquelettiques chez les soignants hospitaliers

Psychosocial factors, the burnout and the musculoskeletal disorders coexist in health professionals at the hospital. From 176 answers to a questionnary built from Karasek (1990) and Siegrist (1996) theories of psychosocial factors, Shirom (2004) of burnout and vigor and finally Kuorinka (1987) of musculoskeletal disorders, we measure and put in link these different aspects, then we propose a predictive model for burnout and pains.     

Self-determination theory and diminished functioning: the role of interpersonal control and psychological need thwarting

Drawing from self-determination theory, three studies explored the social-environmental conditions that satisfy versus thwart psychological needs and, in turn, affect psychological functioning and well-being or ill-being. In cross-sectional Studies 1 and 2, structural equation modeling analyses supported latent factor models in which need satisfaction was predicted by athletes' perceptions of autonomy support, and need thwarting was better predicted by coach control. Athletes' perceptions of need satisfaction predicted positive outcomes associated with sport participation (vitality and positive affect), whereas need thwarting more consistently predicted maladaptive outcomes (disordered eating, burnout, depression, negative affect, and physical symptoms). In addition, athletes' perceptions of psychological need thwarting were significantly associated with perturbed physiological arousal (elevated levels of secretory immunoglobulin A) prior to training. The final study involved the completion of a diary and supported the relations observed in the cross-sectional studies at a daily level. These findings have important implications for the operationalization and measurement of interpersonal styles and psychological needs.
