Depression and decision-making among intravenous drug users

Two short scales, the TCU Depression Scale and the TCU Decision-making Scale, were psychometrically evaluated in a sample of 145 intravenous drug users. Coefficient alpha reliabilities were .78 for the 6-item TCU Depression Scale and .77 for the 9-item TCU Decision-making Scale. Concurrent validity of the former scale was assessed by correlating scores with those on the Beck Depression Inventory, r = .75. Based on the Beck Depression Inventory Clinical cutoff scores, 83% of the sample showed some depression, with 23% severely depressed, 39% moderately depressed, and 21% mildly depressed. Individuals scoring higher on depression on both tests tended to score lower on decision-making. Significant demographic associations of age, gender, education, and race-ethnicity were found for the depression and decision-making scales. More depression was noted for women, those younger, white, and having less education. Older and more educated intravenous drug users tended to score higher on decision-making. Validity for the depression and decision-making scales was assessed by examining correlations with behaviors. Significant positive correlations were found between depression scores and intravenous use of cocaine only, heroin and cocaine combined, and heroin only. Also, intravenous use of cocaine only and of cocaine and heroin combined were negatively related to decision-making. AIDS sex-risky behavior was positively correlated with depression and negatively correlated with decision-making.     

The comparative efficacy of Milan family therapy for disturbed children and their families

This paper describes a study comparing the efficacy of Milan family therapy with that of other treatments routinely used in an out-patient child psychiatry department. Some 118 subjects were allocated on a random, prospective basis to one of two treatment groups, the Milan family therapy group or the other treatments group. The methods of assessment included semi-structured interviews, questionnaires, visual analogue scales and standardized therapy schedules. The results showed that whilst subjects in both treatment groups achieved comparable symptomatic improvement at the end of treatment and at six-month follow-up, the Milan approach produced more changes for family members other than the referred child as well as requiring less treatment time than the other treatments.     

Attachment and anger in an anxiety-provoking situation.

In this study, women were told they would engage in an anxiety-provoking activity. Women then waited with their dating partner for the activity to begin. During this 5-min "stress" period, each couple's interaction was videotaped unobtrusively. Each couple was then told that the woman would not have to do the stressful activity, and each couple was unobtrusively videotaped again during a 5-min "recovery" period. The behavior of both partners was then coded during both periods. The major results revealed that more-avoidant men displayed greater anger during the stress period, especially if their partners were more anxious or distressed or sought more support from them. More-avoidant women also displayed greater anger, particularly if they were highly anxious or distressed and received little support or encountered anger from their partners. During the recovery period, highly ambivalent women behaved more negatively toward their partners if they had been more anxious in the stress period or had sought more support from their partners. These results are discussed in terms of attachment theory.     

Psychological Foundations of Trust

ABSTRACT— Trust lies at the foundation of nearly all major theories of interpersonal relationships. Despite its great theoretical importance, a limited amount of research has examined how and why trust develops, is maintained, and occasionally unravels in relationships. Following a brief overview of theoretical and empirical milestones in the interpersonal-trust literature, an integrative process model of trust in dyadic relationships is presented.     

The production of bimanual percussion in 12- to 24-month-old children

Bimanual coordination represents a complex self-organizing system that is subject to both internal and contextual constraints. Although there has been interest in examining bimanual development throughout the lifespan, few data exist relative to the bimanual activity of children between 1 and 4 years of age. The study reported here represents an initial effort to address this gap. Twenty-seven children who were either 12, 18 or 24 months old were videotaped while drumming with sticks on a plastic drum. Two independent observers recorded bout length as well as number and phase relation of movement cycles within bouts. Kinematic analysis provided more detailed information about the timing and form of children's activity. Results indicate that bimanual drumming becomes preferred over unimanual drumming by 2 years of age, that the proportions of different phase relations exhibited by children change between 1 and 2 years of age, and that the behavior appears to go through periods of stability and variability within this age range. These results are discussed in the context of the child's physical development and interactions with the environment during this period.     

Vitamins, minerals, and mood

In this article, the authors explore the breadth and depth of published research linking dietary vitamins and minerals (micronutrients) to mood. Since the 1920s, there have been many studies on individual vitamins (especially B vitamins and Vitamins C, D, and E), minerals (calcium, chromium, iron, magnesium, zinc, and selenium), and vitamin-like compounds (choline). Recent investigations with multi-ingredient formulas are especially promising. However, without a reasonable conceptual framework for understanding mechanisms by which micronutrients might influence mood, the published literature is too readily dismissed. Consequently, 4 explanatory models are presented, suggesting that mood symptoms may be expressions of inborn errors of metabolism, manifestations of deficient methylation reactions, alterations of gene expression by nutrient deficiency, and/or long-latency deficiency diseases. These models provide possible explanations for why micronutrient supplementation could ameliorate some mental symptoms.     

Effectiveness of Dialectical Behavior Therapy in a Community Mental Health Center

Dialectical behavior therapy (DBT) has been shown to be effective in randomized controlled trials with women with borderline personality disorder and histories of chronic self-inflicted injury including suicide attempts. The present study is a pre-post replication of a comprehensive DBT program in a community mental health center for individuals who chronically injure themselves and/or have experienced multiple treatment failures. Twenty-four subjects were given the Treatment History Interview to obtain information regarding medically treated self-inflicted injuries and the use of crisis services. After 1 year of treatment, DBT showed a significant reduction in the number and severity of self-inflicted injuries, psychiatric-related emergency room visits, psychiatric inpatient admissions and days, and the number of crisis treatment systems engaged. Results are compared to benchmarks from 3 other clinical trials of DBT. While this pre-post comparison has threats to internal validity, it supports the feasibility of DBT when fully implemented in a community mental health clinic.     

Getting in People’s Faces: On the Symbiotic Relationship between the Media and Police Gang Units

The current study explores the relationships among high-profile homicide incidents, media representations of gang homicides, and the establishment of specialized police task forces in British Columbia, Canada. The sample includes all articles on homicide published between 2004 and 2010 in a major daily newspaper (N = 2,873). We examine the attention given to gang-related homicides compared to other homicides, explore the impact of high-profile shootings on trends in reporting, and discuss the timing of media reports in relation to the creation of specialized police forces. Results are discussed with respect to the symbiotic relationship between police organizations and the media.
