Acceptance and Commitment Therapy for Self-Stigma Around Sexual Orientation: A Multiple Baseline Evaluation

This study evaluated the effectiveness of 6 to 10 sessions of Acceptance and Commitment Therapy (ACT) for self-stigma around sexual orientation linked to same-sex attraction (what has generally been referred to as internalized homophobia; IH) in a concurrent multiple-baseline across-participants design. Three men and 2 women showed sizeable reductions from baseline to posttreatment and to 4- and 12-week follow-ups in daily reports of the degree to which thoughts about sexual orientation interfered in their lives; distress associated with these thoughts also decreased. Positive changes were observed in self-report measures of IH, depression, anxiety, stress, quality of life, and perceived social support. Consistent with the theory underlying ACT, reductions in daily ratings of the believability of thoughts about same-sex attraction (a process variable) were greater than those observed for frequency of such thoughts. Improvements were also observed in questionnaires measuring ACT processes. Mixed regression analyses confirmed outcome and process effects that were apparent through visual inspection. Implications and the distinctiveness of ACT as an approach are discussed.     

Pathways to Lifespan Health Following Childhood Parental Death

The death of a parent is a profoundly stressful form of childhood adversity, increasing the short‐ and long‐term risk of mental health problems. Emerging research suggests it may also disrupt biological regulatory systems and increase the risk of long‐term physical health problems. This article presents a theoretical framework of the process by which the experience of parental death during childhood may influence mental and physical health outcomes over time. Drawing from a broad literature on adaptation following childhood parental loss, we focus on risk and protective factors in the childhood environment that are theoretically and empirically linked to emotional and biological regulatory responses to stress later in life, the effects of which may accumulate to impact long‐term health.     

The Contributing Role of Negative Affectivity and Experiential Avoidance to Increased Cardiovascular Risk

Depression and anxiety are independent risk factors for the onset of cardiovascular disease, independent of classical risk factors, such as smoking, obesity, or hypertension. The present paper argues that the tendency to avoid difficult thoughts and feelings helps explain this relationship. There is a strong positive relationship between experiential avoidance and negative affectivity. Experiential avoidance is also related to several health behaviors recognized for increasing cardiovascular risk and may help functionally explain why individuals engage in problematic behaviors, such as smoking, drinking, and binge eating. Treatments that undermine experiential avoidance could be useful psychosocial approaches to cardiovascular risk reduction.     

Integrated Schooling and Religious Tolerance in Northern Ireland

The design of educational institutions has long been seen as a key element in determining social divisions. This article examines the long-term impact of separate and integrated education on relations between the two religious communities (Catholics and Protestants) in Northern Ireland. Using a large-scale survey, the results suggest that in comparison to their previously separate counterparts, individuals who attended an integrated school are more likely to be understanding and respectful of the culture and traditions of others. The finding holds even after a range of background characteristics are taken into account. The results have implications for the role of segregated educational institutions in ameliorating religious, ethnic or racial division in other post-conflict societies. The Northern Ireland evidence suggests that a segregated school system rather than ameliorating intolerance and division may end up exacerbating and reinforcing it.     

Representational momentum when attention is divided

Observers tend to misremember a transforming object's final appearance as further along in the direction of continued transformation. This forward bias, termed representational momentum (RM), suggests that the dynamics associated with an object cannot be ignored in the effort to remember a particular instance of the object. Two experiments tested how attentional focus affects this memory bias. Observers attended to one object, divided attention across more than one object, or performed a secondary task simultaneously with the RM task. For objects translating in space, diminished attention increased the forward memory shift, suggesting that under distraction, motion can be represented but the stopping point is less effectively represented. We propose that object dynamics are well represented when attention is distracted, but that representing a change—including stopping—in the dynamics requires attention. We suggest some experiments to examine this proposal further.     

Learning about cues that prevent an outcome: Conditioned inhibition and differential inhibition in human predictive learning

Summation tests were used to assess whether participants in a human predictive judgement task learned that some cues (foods) prevented the occurrence of the outcome (migraine). In three experiments the preventative effect of a conditioned inhibitor, I, trained in the design, P+, PI-, I-, was stronger than that of a negative control cue, N, that had been presented alone with the same frequency and simply predicted no outcome. This control cue, N, also passed the summation test when compared to a novel control cue. Experiments 2 and 3 examined whether the latter negative control effect was attributable to differential inhibition. Manipulations designed to alter context learning and the magnitude of the negative contingency did not affect the properties of the negative control cue. Thus, these experiments did not support the possibility that a cue given simple negative training acquires differential inhibition. Regardless of the mechanism underlying the negative control effect, the consistent finding that the conditioned inhibition cue, I, reduced prediction of the outcome more than did the negative control cue, N, provides evidence for true conditioned inhibition whose acquisition requires co-occurrence of the preventative cue with a positive training cue.
