Obsessive Compulsive Symptoms Predict Posttraumatic Growth: A Longitudinal Study

Although posttraumatic growth (PTG) has received growing attention, the relationship between PTG and distress remains unclear. This longitudinal study examines the relationship between posttraumatic obsessive-compulsive (OC) symptoms and PTG. Israeli veterans were followed over 17 years using self-report questionnaires of OC symptoms, posttraumatic stress disorder (PTSD), and PTG. Hierarchical regression analyses demonstrated that OC symptoms predicted PTG, even when initial PTG levels and PTSD symptoms were controlled for in the combatants group. These preliminary findings suggest that OC symptoms may play an important role in facilitating psychological growth. Future research is warranted to explore the mechanisms responsible for this relationship.     

Proximal and Distal Defense: A New Perspective on Unconscious Motivation

Death-related thoughts produce different effects on thought and behavior when they are in current focal attention and when they are on the fringes of consciousness. When such thoughts are conscious, people attempt to either remove them from consciousness or push death into the distant future by distorting their beliefs to logically imply that they have many remaining years to live. When such thoughts are highly accessible but outside current focal attention, people increase efforts to view themselves as persons of value living in a meaningful universe. In this way, awareness of the inevitability of death produces diverse effects on human thought and behavior that bear little obvious resemblance to the problem of death.     

Coping with war captivity: the role of attachment style

The current study examines the implication of attachment style in both immediate coping and long-term adjustment of prisoners of war (POWs). 164-ex-POWs and 184 matched controls filled out a battery of questionnaires, 18 years after the war. They were questioned about their subjective experience of captivity, current mental health status, and characteristic attachment style. Secure individuals, who reported lower levels of suffering, less helplessness and more active coping during captivity, exhibited better long-term adjustment. Avoidant ex-POWs, who reported helplessness and hostility, and ambivalent individuals, who felt abandoned and vulnerable, reported long-term maladjustment. The role of attachment style as a stress-moderating resource is discussed. © 1998 John Wiley & Sons, Ltd.     

Long-Term Guilt and Hostility Underlying Posttraumatic Stress Symptoms in War Combatants and Ex-Prisoners of War

The link between posttraumatic guilt and posttraumatic stress disorder has gained recognition over the past decades and was recently expressed in the modifications made to the diagnostic criteria for the disorder under the DSM-V. Yet, the psychological dynamics underlying this relation are still not fully understood. The present study introduces a model whereby different dynamics between guilt and hostility are related to posttraumatic stress disorder symptoms (PTSS), following different traumatic war experiences. One hundred and forty-four former prisoners of war (ex-POWs) and 143 comparable combatants participated in the study, 30 years after the war, reporting on their PTSS, guilt, and hostility. Moderation analyses revealed a three-way interaction, where high hostility buffered the effect of guilt on PTSS only among ex-POWs. This finding suggests a distinctive dynamic among guilt, hostility, and PTSS following diverse traumatic events. Specifically, it appears that hostility can have a mitigating effect on the negative outcomes of guilt for ex-POWs following trauma, but not for non-POW veterans. The theoretical reasoning and the clinical implications of these findings are discussed.     

Money, Housework, Sex, and Conflict: Same-Sex Couples in Civil Unions, Those Not in Civil Unions, and Heterosexual Married Siblings

In this study we examined the division of finances, the division of household tasks, relationship maintenance behaviors, sexual activity, monogamy, and conflict among same-sex couples who had had civil unions in Vermont, same-sex couples who had not had civil unions recruited from their friendship circles, and married heterosexual couples recruited from among their siblings. Married heterosexuals had a more traditional, gendered division of finances, household tasks, and relationship maintenance behaviors, even though the heterosexuals were all siblings or in-laws of lesbians or gay men. Sexual orientation was a stronger predictor of the division of household tasks than was income difference within couples. Lesbians reported less frequent sexual activity than married heterosexual women, and gay men were less monogamous than married heterosexual men. Gay men in civil unions differed on a few variables from gay men not in civil unions, but there were no differences among lesbians.     

Interference and facilitation from partners in the development of interdependence within romantic relationships

To clarify how interdependence develops, we employ Berscheid's (1983) emotional investment perspective to illuminate the ways intimacy maps onto interference and facilitation from romantic partners. We conducted a cross‐sectional, self‐report study involving 498 individuals. As anticipated, we found a small nonlinear association between intimacy and interference from partners, a positive association between intimacy and facilitation from partners, and an interaction between intimacy and influence from partners that predicted interference. Notably, however, intimacy did not interact with influence to predict facilitation. Interference and facilitation were positively correlated at the bivariate level and negatively correlated when influence was covaried. We discuss how our findings characterize developing interdependence across the life span of courtship.     

Observers can voluntarily shift their psychometric functions without losing sensitivity

Psychometric sensory discrimination functions are usually modeled by cumulative Gaussian functions with just two parameters, their central tendency (μ) and their slope (1/σ). These correspond to Fechner's "constant" and "variable" errors, respectively. Fechner pointed out that even the constant error could vary over space and time and could masquerade as variable error. We wondered whether observers could deliberately introduce a constant error into their performance without loss of precision. In three-dot vernier and bisection tasks with the method of single stimuli, observers were instructed to favour one of the two responses when unsure of their answer. The slope of the resulting psychometric function was not significantly changed, despite a significant change in central tendency. Similar results were obtained when altered feedback was used to induce bias. We inferred that observers can adopt artificial response criteria without any significant increase in criterion fluctuation. These findings have implications for some studies that have measured perceptual "illusions" by shifts in the psychometric functions of sophisticated observers.
