Ethnic differences in clinical presentation of depression in adult women

This study examined ethnic differences in self-report and interviewer-rated depressive symptoms and estimated the contributions of sociodemographic and psychosocial factors in predicting severity of depression. One hundred twenty-five clinically depressed African American (n = 46), Caucasian (n = 36), and Latina (n = 43) women were recruited. After controlling for differences in socioeconomic status, African American women reported more symptoms of distress and Latinas were rated as significantly more depressed than the other groups. However, these ethnic differences were not moderated by either education or employment. Finally, hierarchical regression analysis indicated that severity of depression was predicted by low education, being single, being Latina, high perceived stress, and feelings of hopelessness. Additional research is needed to validate these results and to investigate their clinical significance.     

Coping with Gulf War combat stress: mediating and moderating effects

The authors examined relationships between method of coping with combat-related stress and psychological symptoms among Gulf War Army personnel (N = 1,058). Participants were surveyed on return from the Gulf region (Time 1) with the Coping Responses Inventory (R. Moos, 1990) and a measure of combat exposure. Outcomes were symptom measures of posttraumatic stress disorder (PTSD) and depression. At Time 2 (18-24 months) participants completed the same symptom measures and an index of postwar stress. Higher proportions of approach-based coping in the war zone were related to lower levels of psychological symptoms. Combat exposure moderated the effects of coping on Time 1 PTSD. Coping predicted changes in symptoms of depression but not PTSD. Combat exposure affected changes in depression through postwar stress but had a direct negative effect on PTSD.     

The social consequences of expressive suppression

At times, people keep their emotions from showing during social interactions. The authors' analysis suggests that such expressive suppression should disrupt communication and increase stress levels. To test this hypothesis, the authors conducted 2 studies in which unacquainted pairs of women discussed an upsetting topic. In Study 1, one member of each pair was randomly assigned to (a) suppress her emotional behavior, (b) respond naturally, or (c) cognitively reappraise in a way that reduced emotional responding. Suppression alone disrupted communication and magnified blood pressure responses in the suppressors' partners. In Study 2, suppression had a negative impact on the regulators' emotional experience and increased blood pressure in both regulators and their partners. Suppression also reduced rapport and inhibited relationship formation.     

Group cognitive behavioural therapy for heterogeneous anxiety disorders

Evidence assessing the outcome of cognitive behavioural therapy for anxiety is based on protocols specifically tailored for individual disorders. To date, there is little research that would assess a mode of delivery that is designed for routine service delivery in typical clinical settings, i.e. group cognitive behavioural therapy for unselected, mixed groups of anxiety disorders. The objective of this pilot study is to use program evaluation methods to assess the immediate and enduring improvements following a 12-week Anxiety Management Group. Group participants had any of 5 anxiety disorders and described related avoidance. The weekly 2-hour group sessions and daily homework tasks were guided by a participant handbook. Patients completed questionnaires at baseline and group completion (n = 70); a subset also provided 6-month follow-up data. The results from post-group scores on 2 self-report measures show immediate reductions equivalent to an effect size of eta = 0.73 (p < 0.001). The effect is maintained at 6-month follow-up. This program evaluation suggests that group cognitive behavioural therapy for heterogeneous anxiety disorders may be effective in a routine clinical setting. A more rigorous study of this heterogeneous format appears justified.     

Transfer of skill engendered by complex task training under conditions of variable priority

We explored the theoretical underpinnings of a commonly used training strategy by examining issues of training and transfer of skill in the context of a complex video game (Space Fortress, Donchin, 1989). Participants trained using one of two training regimens: Full Emphasis Training (FET) or Variable Priority Training (VPT). Transfer of training was assessed with a large battery of cognitive and psychomotor tasks ranging from basic laboratory paradigms measuring reasoning, memory, and attention to complex real-world simulations. Consistent with previous studies, VPT accelerated learning and maximized task mastery. However, the hypothesis that VPT would result in broader transfer of training received limited support. Rather, transfer was most evident in tasks that were most similar to the Space Fortress game itself. Results are discussed in terms of potential limitations of the VPT approach.     

Hydrocortisone infusion exerts dose- and sex-dependent effects on attention to emotional stimuli

Glucocorticoid administration has been shown to exert complex effects on cognitive and emotional processing. In the current study we investigated the effects of glucocorticoid administration on attention towards emotional words, using an Affective Go/No-go task on which healthy humans have shown an attentional bias towards positive as compared to negative words. Healthy volunteers received placebo and either low-dose (0.15 mg/kg) or high-dose (0.45 mg/kg) hydrocortisone intravenously during two separate visits in a double-blind, randomized design. Seventy-five minutes post-infusion, the subjects performed tests of attention (Rapid Visual Information Processing [RVIP]), spatial working memory (Spatial Span) and emotional processing (Affective Go/No-go task [AGNG]). On the attention task, performance was impaired under both hydrocortisone doses relative to placebo, though the effect on error rate was not significant after controlling for age; Spatial Span performance was unaffected by hydrocortisone administration. On the AGNG task, relative to the placebo condition the low-dose hydrocortisone infusion decreased response time to emotional words while high-dose hydrocortisone increased response time. In the females specifically, both high and low dose hydrocortisone administration attenuated the normal attentional bias toward positively valenced words. These data suggest that, in healthy women, the modulation of attention by the emotional salience of stimuli is influenced by glucocorticoid hormone concentrations.     

“It’s Really No Big Deal”: The Role of Social Supply Networks in Normalizing Use of Cannabis by Students at Canadian Universities

Cannabis (marijuana) has undergone a normalizing process as indicated by high use rates, social tolerance, and broader cultural acceptance of its use in many countries. Users also maintain access through extended friendship networks that facilitate the cultural diffusion of the practice. The social nature of supply is herein theorized in terms of Goffman’s understanding of activities that function to preserve a sense of normalcy as a collective achievement enabling predictable constructions of reality. Based on in-depth interviews with undergraduate students, we explore how social networks of supply—characterized by casual access, reciprocity, and sharing—contribute to shared meanings about using marijuana as an unremarkable or “normal” thing to do.     

The Weapon Focus Effect in Target‐Present and Target‐Absent Line‐Ups: The Roles of Threat,Novelty, and Timing

When an eyewitness suffers an impairment of memory for a perpetrator because the criminal used a weapon during the crime, this impairment is called the weapon focus effect. The literature is split on how this arises: Some implicate the narrowing of attentional cues to the weapon because the arousal of the victim increases, whereas others claim that the weapon is a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm featuring a normal, novel, or threatening object. Timing of the object's presentation was manipulated such that it was visible before, after, or during the time when the culprit's face was visible. Target‐present and target‐absent line‐ups as well as retrospective questions were administered. Both the novel object and the weapon resulted in increased mistaken identifications in target‐absent line‐ups. Structural equation modeling suggested that object novelty mediated this effect.
