Parenting Interventions for Children with Autism Spectrum and Disruptive Behavior Disorders: Opportunities for Cross-Fertilization

Empirical support exists for parent training/education (PT/PE) interventions for children with disruptive behavior disorders (DBD) and autism spectrum disorders (ASD). While the models share common roots, current approaches have largely developed independently and the research findings have been disseminated in two different literature traditions: mental health and developmental disabilities. Given that these populations often have overlapping clinical needs and are likely to receive services in similar settings, efforts to integrate the knowledge gained in the disparate literature may be beneficial. This article provides a systematic overview of the current (1995–2005) empirical research on PT/PE for children with DBD and ASD; attending to factors for cross-fertilization. Twenty-two ASD and 38 DBD studies were coded for review. Literature was compared in three main areas: (1) research methodology, (2) focus of PT/PE intervention, and (3) PT/PE procedures. There was no overlap in publication outlets between the studies for the two populations. Results indicate that there are opportunities for cross-fertilization in the areas of (1) research methodology, (2) intervention targets, and (3) format of parenting interventions. The practical implications of integrating these two highly related areas of research are identified and discussed.     

Response styles among patients with minor depression and dysthymia in primary care

Ruminative responses to depression have predicted duration and severity of depressive symptoms. The authors examined how response styles change over the course of treatment for depression and as a function of type of treatment. They also examined the ability of response styles to predict treatment outcome and status at follow-up. Primary care patients (n = 96) with dysthymia or minor depression were randomly assigned to problem-solving therapy, paroxetine, or placebo. Patients' depressive symptoms and rumination, but not distraction, decreased over time. Pretreatment rumination and distraction were associated with more depressive symptoms at the conclusion of treatment; the latter finding was not consistent with the response style theory of depression. Results are discussed in terms of their implications for this theory.     

Most adults show opposite-side biases in the imagined holding of infants and objects

Three hundred university undergraduates were asked to imagine holding in their arms first an object (either an "expensive vase" or an "old shoebox") and then a young infant. For all three tasks, side biases were found that were significantly different from chance and from one another: 81% of the subjects reported holding the imagined vase in their right arm, 64% reported holding the imagined shoebox in their right arm, and 66% reported holding the imagined infant in their left arm. These results further support the hypothesis that the left-side bias is unique to infants and, for the first time, establish this through direct comparisons of holding-side biases for infants and objects within subjects. The sex and handedness of the holder as well as the qualities of the imagined object also were found to contribute to the side and strength of the bias.     

The contribution of novel brain imaging techniques to understanding the neurobiology of mental retardation and developmental disabilities

Studying the biological mechanisms underlying mental retardation and developmental disabilities (MR/DD) is a very complex task. This is due to the wide heterogeneity of etiologies and pathways that lead to MR/DD. Breakthroughs in genetics and molecular biology and the development of sophisticated brain imaging techniques during the last decades have facilitated the emergence of a field called Behavioral Neurogenetics. Behavioral Neurogenetics focuses on studying genetic diseases with known etiologies that are manifested by unique cognitive and behavioral phenotypes. In this review, we describe the principles of magnetic resonance imaging (MRI) techniques, including structural MRI, functional MRI, and diffusion tensor imaging (DTI), and how they are implemented in the study of Williams (WS), velocardiofacial (VCFS), and fragile X (FXS) syndromes. From WS we learn that dorsal stream abnormalities can be associated with visuospatial deficits; VCFS is a model for exploring the molecular and brain pathways that lead to psychiatric disorders for which subjects with MR/DD are at increased risk; and finally, findings from multimodal imaging techniques show that aberrant frontal-striatal connections are implicated in the executive function and attentional deficits of subjects with FXS. By deciphering the molecular pathways and brain structure and function associated with cognitive deficits, we will gain a better understanding of the pathophysiology of MR/DD, which will eventually make possible more specific treatments for this population.     

Negative cognitive styles, dysfunctional attitudes, and the remitted depression paradigm: a search for the elusive cognitive vulnerability to depression factor among remitted depressives

Results from studies using a behavioral high-risk design and approximations to it generally have corroborated the cognitive vulnerability hypothesis of depression, whereas results from remitted depression studies typically have not. Suspecting that design features of previously conducted remitted designs likely precluded them from detecting maladaptive cognitive patterns, the authors conducted a study featuring the remitted design that has been successful in studies of a biological vulnerability for depression. Participants' current depressive symptoms, negative cognitive styles (hopelessness theory), dysfunctional attitudes (Beck's theory), and lifetime prevalence of clinically significant depression were assessed. Participants who had remitted from an episode of clinically significant depression had more negative cognitive styles, but not greater levels of dysfunctional attitudes, than did never depressed individuals.     

An analysis of response-blocking parameters in the prevention of pica

We manipulated two parameters of response blocking to reduce pica: (a) the criteria for initiating the procedure (either earlier or later in the response chain) and (b) the distance from which the procedure was initiated. Results suggested that response blocking may be effective only when implemented early in the chain and with near-perfect consistency. Further, additional treatment components may be required to eliminate all pica attempts.     

Responding to persons with mental illnesses: police perspectives on specialized and traditional practices

Persons with mental illnesses increasingly come into contact with police in the community due to changes in local and national policies and police responsibility for maintaining order. Recently, specialized intervention strategies have been advanced to ensure that persons with mental illnesses are not inappropriately arrested and moved into the criminal justice system. This study builds on previous research undertaken on police perceptions of dealing with persons with mental illnesses in the community and effectiveness of response (see Borum et al., 1998). A subsample of 182 officers from the Newark, NJ, Police Department was surveyed and added to a sample of 452 officers from three agencies with specialized responses to persons with mental illnesses. The authors conclude that, despite a non-specialized response to this population, the actual and perceived effectiveness of Newark's strategy is similar to (and in some cases better than) that which is observed in the agencies with specialized response programs. Implications for implementing specialized responses for persons with mental illnesses are discussed.     

Predicting Re-Victimization of Battered Women 3 Years After Exiting a Shelter Program

This study examined interpersonal and ecological predictors of re-victimization of a sample of women with abusive partners. All women (N = 124) had sought refuge from a battered women’s shelter 3 years earlier, and half the sample had been randomly assigned to receive free, short-term advocacy services immediately upon exit from the shelter. Results 2 years post-intervention revealed positive change in the lives of participants (C. M. Sullivan & D. Bybee, 1999), including a decrease in abuse for women who had worked with advocates. The current study examined intervention effects 3 years after the program ended, as well as other predictors of re-abuse. Nineteen percent of the original sample had experienced domestic violence between 2 and 3 years after shelter exit (65% by current partners, 35% by ex-partners). The advocacy program’s effect on risk of re-victimization did not continue 3 years post-intervention. However, having worked with an advocate 3 years prior continued to have a positive impact on women’s quality of life and level of social support. The risk of being abused 3 years post-shelter stay was exacerbated by a number of factors present 1 year prior, including women’s (1) having experienced abuse in the 6 months before that point; (2) having difficulties accessing resources; (3) having problems with the state welfare system; and (4) having people in their social networks who made their lives difficult. Women were at less risk of abuse if, 1 year earlier, they (1) were employed; (2) reported higher quality of life; and (3) had people in their networks who provided practical help and/or were available to talk about personal matters. These findings support the hypothesis that access to resources and social support serve as protective factors against continued abuse.     

Visual search and the collapse of categorization

Categorization researchers typically present single objects to be categorized. But real-world categorization often involves object recognition within complex scenes. It is unknown how the processes of categorization stand up to visual complexity or why they fail facing it. The authors filled this research gap by blending the categorization and visual-search paradigms into a visual-search and categorization task in which participants searched for members of target categories in complex displays. Participants have enormous difficulty in this task. Despite intensive and ongoing category training, they detect targets at near-chance levels unless displays are extremely simple or target categories extremely focused. These results, discussed from the perspectives of categorization and visual search, might illuminate societally important instances of visual search (e.g., diagnostic medical screening).     

Development and evaluation of school-based violence prevention programs

Discusses key issues in developing and evaluating school-based violence prevention interventions. Schools provide a natural setting for implementing programs directed at teaching youth attitudes, knowledge, and skills to reduce their involvement in violence. Although multitudes of these programs exist, few have been rigorously evaluated. Developers of violence prevention programs need to pay particular attention to the type of violence being addressed, the target population, relevant risk and protective factors, and the target of the intervention. Conducting sound evaluations of such programs requires careful attention to the unit of randomization, treatment conditions, outcome measures, timing of data collection, and potential moderator variables. Efforts to develop effective prevention programs can be greatly facilitated by adopting an action-research strategy in which evaluation findings provide a basis for continual program refinement.
