Intergenerational Continuity in Depression: The Importance of Time-Varying Effects,Maternal Co-morbid Health Risk Behaviors and Child’s Gender

Intergenerational continuity in depressive symptoms is well established between mother and child, but there are still important facets of this relationship that are underexplored. We examine intergenerational continuity in depressive symptoms between mother–child dyads as a flexible function of child age and account for the potential moderating role of maternal co-morbid health risk behaviors. Using prospective, self-report data collected yearly from 413 mother–child dyads (210 mother–son dyads and 203 mother–daughter dyads) between child ages 12–17, the results indicate that the effect of maternal depressive symptoms on daughters’ depressive symptoms steadily increases throughout adolescence whereas the effect of maternal depressive symptoms on sons’ depressive symptoms is relatively small, stable, and non-significant during mid-adolescence before increasing in effect in later adolescence. A positive interactive effect between maternal depressive symptoms and intimate partner violence is observed for sons and maternal depressive symptoms and substance use for daughters. A negative interactive effect of maternal depressive symptoms and substance use is observed among sons. Overall, this study identifies particular subgroups for whom intervention programming is most beneficial and suggests targeting health risk behaviors of mothers to lessen the impact of maternal depressive symptoms on offspring.     

Maternal Depressive Symptoms and Adolescent Health Risk Problems: The Role of School Engagement

Maternal depressive symptoms disrupt positive youth development, though the pervasiveness of this disruption is understudied. Additionally, it remains unknown whether prosocial factors such as adolescent school engagement may buffer against this risk factor. Using multigenerational, longitudinal data spanning ten years from an ethnically diverse sample of mother-child dyads (66% Black, 17% Hispanic, and 17% White), this study examines the effect of maternal depressive symptoms in late childhood (ages 8–13) on the development and progression of offspring depressive symptoms, substance use, and delinquent behavior during adolescence (ages 14–17). Further, the study examines whether school engagement moderates the ill effects of maternal depressive symptoms. Mother-son (n?=?212) and mother-daughter (n?=?215) dyads are compared to assess for similarities and differences between male and female offspring. The results indicate that offspring of mothers with greater maternal depressive symptoms are more likely to display higher levels of depressive symptoms, substance use, and delinquency throughout adolescence, although important nuances emerge across outcome and child sex. Additionally, while school engagement itself is associated with reduced depressive symptoms, substance use and delinquency among adolescents, it is not profound enough to offset the risk posed by maternal depressive symptoms. The findings of this study reinforce the pervasive, negative, intergenerational impact of maternal depressive symptoms and has implications for prevention and intervention efforts for adolescent health risk problems.

     

A comparison of fatal with non-fatal knife injuries in Edinburgh

Assault using a knife is a common problem in the United Kingdom. Between February 1992 and December 1996, 120 individuals died or received hospital treatment in Edinburgh after being assaulted with a knife. Twenty individuals (17%) died as a result of their injuries. Comparison of the survivors with non-survivors revealed both groups to have similar age and sex distributions, but those who died had significantly more severe injuries when scored according to the Abbreviated Injury Scale. Eight individuals died of unsurvivable chest injuries at the scene of the attack and of the remainder, only five reached hospital with signs of life. Analysis of hospital treatment using TRISS methodology revealed there to be two unexpected survivors and no unexpected deaths. The risk of death appears to depend mostly upon injuries sustained and also to a lesser extent upon other factors such as alcohol consumption and the presence of a bystander capable and willing to request emergency medical assistance. There does not appear to be much potential to save lives by improving hospital treatment for those assaulted with a knife in Edinburgh. Instead, greater focus needs to be placed upon rapid transfer to hospital and upon restricting the possession and use of knives.     

Concentrations of Opiates and Psychotropic Agents in Polydrug Overdoses: A Surprising Correlation Between Morphine and Antidepressants

Abstract: The relationship between postmortem concentrations of morphine and co‐detected psychoactive drugs in fatal overdoses is examined. Morphine and other drugs were detected in 161 medicolegal autopsy cases. Subsets of these morphine‐positive cases based on drug class were established, including opioids, antidepressants, ethanol, benzodiazepines, and “other.” Each subset was split into high or low concentration groups based on median drug concentrations. Morphine concentrations of the [high] and [low] groups were compared, with no significant difference in morphine concentration identified in the opioid, ethanol, or benzodiazepine subsets. The “other” drug class was too heterogeneous for statistical assessment. Morphine concentrations did show a significant direct relationship (p = 0.01) with antidepressants, namely increased concentrations of antidepressant drugs are associated with an increased concentration of morphine. This trend probably remains even after excluding cocaine‐positive cases. The unsuspected finding that postmortem concentrations of antidepressants positively correlate with morphine levels may be important in the treatment of depression in drug addicts.     

PARENTING COORDINATION AND COURT RELITIGATION: A CASE STUDY

This case study explores the degree to which the number of court motions changed 1 year after parenting coordination was implemented with high-conflict co-parenting couples and examines the parents' demographic profile. Findings indicate a reduction of approximately 75% in child-related court filings, as well as a 40% decrease in other motions, resulting in a decrease of 50% in all motions filed, thus saving these once high-conflict couples, and the court, significant time and resources. The diverse demographic profile illuminates training and research implications regarding the use of parenting coordination as an intervention for high-conflict co-parenting couples.

Research and development project selection in the public sector

This article argues for an innovative methodology to appraising (ex ante) longer-term strategic research and development (R&D) investments. This methodology reflects the inherent value of such R&D in terms of opening up opportunities (but not obligations) for investment in new technological areas with potentially substantial returns. Although corporate R&D managers and public administrators describe the merits of long-term research on these grounds, only recently has the qualitative argument been replaced by the foundations of a methodology capable of quantifying this inherent value of R&D. Such a methodology could also facilitate a transition toward the use of more appropriate discount rates other than the unvarying rates of traditional methodologies.
