Predictors and moderators of improved social-emotional functioning in mothers with substance use disorders and their young children enrolled in a relationship-based case management program

Mothers with substance use disorders (SUDs) typically have trauma histories and psychosocial difficulties that lead to poor social-emotional functioning and disrupted mother–child relationships. This 12-month study explored associations of family adverse circumstances and services (case management, therapeutic, and community-based) received by 57-mothers with SUDs and their infants (less than 24-months-old) with changes in social-emotional functioning. All mothers were enrolled in a relationship-based case management program (Parent–Child Assistance Program [PCAP]) that emphasized connecting mothers to appropriate community services. A subset of mothers was additionally provided a trauma-focused psychotherapeutic intervention (infant–parent psychotherapy [IPP]). Dyads in both treatment groups improved in overall social-emotional functioning as assessed by the Functional Emotional Assessment Scale (FEAS). A combined-sample regression analysis revealed that improved FEAS scores were significantly predicted by the number of community services received but not by PCAP case management hours (IPP was not included in this analysis). More adverse circumstances were associated with less improvement in social-emotional functioning in the children; but among the mothers trauma level did not predict FEAS scores. We also found a moderating effect of trauma: Dyads with relatively more adversity showed a significantly greater association of community services received with improvement in FEAS scores than did those with relatively less adversity.     

Cognitive Behavior Couple Therapy-REBT Model for Traumatic Bereavement

Following the loss of a child, couple counseling focuses on their grief process as well as the impact of the loss on the marital relationship. Individual differences in reacting to and coping with the loss, different patterns of grieving, and differences in attitudes about relationship issues may cause further distress and increase marital conflicts and adaptation to the loss. When bereavement occurs under traumatic circumstances, the conflicts may be further complicated and involve problems in daily functioning related to distorted cognitions and attributions connected with traumatic bereavement. In this paper, cognitive grief therapy using the ABC model of REBT with a couple who lost a child under traumatic circumstances will be described.     

Theorising Interventions as Events in Systems

Conventional thinking about preventive interventions focuses over simplistically on the “package” of activities and/or their educational messages. An alternative is to focus on the dynamic properties of the context into which the intervention is introduced. Schools, communities and worksites can be thought of as complex ecological systems. They can be theorised on three dimensions: (1) their constituent activity settings (e.g., clubs, festivals, assemblies, classrooms); (2) the social networks that connect the people and the settings; and (3) time. An intervention may then be seen as a critical event in the history of a system, leading to the evolution of new structures of interaction and new shared meanings. Interventions impact on evolving networks of person-time-place interaction, changing relationships, displacing existing activities and redistributing and transforming resources. This alternative view has significant implications for how interventions should be evaluated and how they could be made more effective. We explore this idea, drawing on social network analysis and complex systems theory.     

A Meta-Analysis of Working Memory Impairments in Autism Spectrum Disorders

Autism spectrum disorders (ASD) are characterized by executive dysfunction, and working memory (WM) comprises one core component of executive function. Many studies have investigated WM impairments in individuals with ASD, however, a conclusive agreement has not been reached. The present study provided a meta-analytic review of WM impairments in individuals with ASD and evaluated potential moderating variables of this problem. Twenty-eight studies were included in this study, and the participants comprised 819 individuals with ASD and 875 healthy controls. A significant WM impairment (Cohen’s d?=??0.61) was identified in the individuals with ASD, however, this impairment was not associated with age. Results of moderation analyses showed that (a) spatial WM was more severely impaired than verbal WM and (b) the component of cognitive processing (maintenance vs. maintenance plus manipulation) did not affect the severity of WM impairments. These findings suggest that WM is impaired in individuals with ASD and may have implications for interventions related to WM impairments in these individuals.     

Stress effects in the hippocampus: synaptic plasticity and memory

It is now well-documented that exposures to uncontrollable (inescapable and unpredictable) stress in adulthood can have profound effects on brain and behavior. Converging lines of evidence from human and animal studies indicate that stress interferes with subsequent performances on a variety of hippocampal-dependent memory tasks. Animal studies further revealed that stress impedes ensuing induction of long-term potentiation (LTP) in the hippocampus. Because the hippocampus is important for key aspects of memory formation and because LTP has qualities congruent to an information storage mechanism, it is hypothesized that stress-induced modifications in hippocampal plasticity contribute to memory impairments associated with stress. Recent studies provide evidence that the amygdala, a structure important in stress- and emotion-related behaviors, plays a necessary role in the emergence of stress-associated changes in hippocampal LTP and memory. Early life stress also alters hippocampal plasticity and memory in a manner largely consistent with effects of adult stress exposure. This review focuses on endocrine-system-level mechanisms of stress effects in the hippocampus, and how stress, by altering the property of hippocampal plasticity, can subsequently influence hippocampal memory.     

Recognizing the un-real McCoy: priming and the modularity of face recognition

Fodor (1983) has proposed that face perception is carried out by an informationally encapsulated module, whose operation is unaffected by context or expectancies. We tested the modularity hypothesis by examining whether discriminations between normal and distorted versions of famous faces can be primed, either by the name of an associated person (semantic context) or by a valid cue as to the identity of the target face (expectancy). A preliminary experiment showed that, in the absence of priming, discriminations between normal and distorted versions of a face were unaffected by whether the target faces were familiar or not, confirming that these judgments tap perceptual, not postperceptual (semantic), coding processes. In Experiment 1, accuracy was significantly higher when target face pairs were preceded by related name primes, as compared with unrelated ones. In Experiment 2, reaction times were significantly faster for targets preceded by a valid identity cue than for targets preceded by an invalid one. Neither effect could be explained as a speed—accuracy tradeoff. These results fail to support Fodor’s conjecture that face processing is encapsulated.
