Hope as a Predictor of Interpersonal Suicide Risk

The current study hypothesized that (1) hope would negatively predict burdensomeness, thwarted belongingness, and acquired capability to enact lethal injury; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results indicated that hope negatively predicted burdensomeness and thwarted belongingness, but positively predicted acquired capability to enact suicide. Contrary to our second hypothesis, hope did not predict suicidal ideation, but interpersonal risk factors for suicide predicted suicidal ideation. Results are discussed in terms of implications for hope theory and Joiner's (2005) interpersonal risk factors for suicide, and for clinical practice.     

Utilizing structural family therapy and systems theory in the business world

The structure of businesses and the structure of families are very similar, considering the fact that so many businesses are owned or operated by families. Structural family therapists who are knowledgeable in systems theory and have an adequate understanding of the underlying concepts of structural family theory (including hierarchy, boundaries, and coalitions) can translate their knowledge to the structure of businesses and organizations. The purpose of this paper is to illustrate the similarities between the structures of families and businesses. In doing so, an application of structural family theory to the business world (employee assistance programs, business consultation, and family businesses) will be demonstrated.     

Perceptions of primary supervisor interpersonal skills: A critical incident analysis

This study surveyed a randomly selected group of Approved Supervisors of the American Association for Marriage and Family Therapy (n = 280) and their supervisees (n = 266) on their perceptions of the primary supervisor interpersonal skill used in supervisory incidents that had a positive effect on supervisee development. Supervisor directiveness was the most identified skill by both supervisors and supervisees.This study was funded in part by grants from the Research Committee of the American Association for Marriage and Family Therapy; the Agricultural Experiment Station, Purdue University; and the School of Liberal Arts and Sciences, Purdue University Calumet.     

Effects of LY354740, a novel glutamatergic metabotropic agonist, on nonhuman primate hypothalamic-pituitary-adrenal axis and noradrenergic function

The search for novel anxiolytics and antidepressants has focused on compounds with the potential to reduce excessive hypothalamic-pituitary-adrenal (HPA) axis activity. L-glutamate, an excitatory neurotransmitter ubiquitously present within the central nervous system, conceivably plays an important role in activating the neural sites involved in stress modulation. Deactivation of the HPA axis by glutamatergic neurotransmission modulation may represent a novel therapeutic approach. Accordingly, the acute intravenous effects of the novel metabotropic (mGlu2/3) agonist LY354740 were tested on bonnet macaques (Macaca radiata) undergoing acute infusions of yohimbine, a noradrenergic stimulant. Dependent measures were the magnitude of the increase of plasma cortisol and plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) customarily elicited by yohimbine. Next, the effects of 6 weeks of chronic oral administration of LY354740 on baseline (postcapture) plasma cortisol and MHPG levels in comparison to the identical measure in untreated controls were assessed. Subjects chronically treated with LY354740 received yohimbine infusions which were compared to yohimbine infusions and saline infusions in non-LY354740-treated subjects. Preliminary evidence supports the view that acute LY354740 infusion resulted in a marked diminution of yohimbine-induced stress response, as manifest by a substantial attenuation of cortisol and MHPG response observed in comparison to the saline-treated yohimbine condition. Chronic oral administration of LY354740 led to postcapture baseline cortisol levels which were markedly reduced (approximately 50 percent) in comparison to untreated control subjects; however, there were no significant parallel differences in MHPG levels. Yohimbine infusions elicited an increase in cortisol and MHPG levels in both LY354740-treated and non-LY354740-treated subjects, in comparison to declines in cortisol values observed following vehicle infusions (group X time interaction; P<.0001). Chronic LY354740-treated subjects failed to achieve cortisol levels comparable in range to those of untreated subjects primarily because of their low baseline cortisol levels. In contrast, despite equivalent baselines, yohimbine-induced MHPG values were increased overall in the chronically treated group compared to the saline and yohimbine-alone groups. Thus, LY354740 markedly reduced the acute corticoid and noradrenergic response elicited by yohimbine infusion. Chronic administration of LY354740 appears to present a safe and effective mechanism to markedly down-modulate the HPA axis while retaining noradrenergic responsivity.

Attachment Security,Personality, and Adjustment of Elementary School Children

Children's development is assumed to be closely related to their attachment security and their personality. The authors’ aim was to examine the joint contribution of attachment security and personality traits to children's adjustment by examining diverse children's outcomes (emotional symptoms, social functioning, and behavioral problems) and using various perspectives (children, parents, and teachers). The sample comprised 247 8–12-year-old children from low socioeconomic status neighborhoods. Personality and attachment contribute to the different domains of adjustment. In cases of moderation, attachment security moderates the implications of personality traits on children's adjustment. The findings highlight the contribution of positive personality tendencies in playing down the difficulties of insecurely attached children.     

Family Relationships,Leaving Home,and Adjustment to Military Service

Associations between family relationships and individual adjustment were studied within a sample of 19-year-old soldiers during their first weeks of basic training. Results showed that family relationships partly explained soldiers' closeness to best friends, number of social nominations, and commanders' ratings of soldiers' military and social competence. In addition, family relations explained soldiers' perceived social competence as assessed via closeness to best friends and number of sociometric nominations. Together, the results reiterate the role played by the family and attitudes toward offspring leaving home and toward their adjustment to military service.
