The objective of this study was to examine associations in youth between antisocial behavior and cardiovascular profile. Younger brothers of adjudicated delinquents (N = 120) received a standardized psychiatric assessment and an assessment of three factors often studied in behavioral cardiology research: family history of hypertension, resting blood pressure, and obesity. As a group, relative to population norms, these youth exhibited signs of obesity and elevated blood pressure, with 30% of the sample appearing clinically obese and 24% having a blood pressure above the 90th percentile for national norms in their age cohort. Within the sample, score on the Child Behavior Checklist (CBCL) Delinquency scale correlated with blood pressure (r = .29-.34) and an index of obesity, weight/height3 (r = .20). Further, scores on the CBCL Delinquency, Aggression, and Externalizing scales were elevated in boys with a positive family history of hypertension. Among boys at risk for delinquency, disruptive psychopathology relates to factors often studied in behavioral cardiology research. Relationships between risk factors for ischemic cardiovascular disease and hostile behavior may be manifested with measures of disruptive psychopathology.

Child and adolescent therapy outcome research findings attest to the efficacy of a variety of treatments. This article illustrates promising treatments for selected internalizing (anxiety and depression), externalizing (oppositional, and antisocial behavior), and other (obesity and autism) conditions, and for other aims (preparation for medical and dental procedures). Studies in these areas illustrate worthwhile characteristics that can help inform the search for empirically supported treatments. These characteristics include randomized controlled trials, well-described and replicable treatments, tests with clinical samples, tests of clinical significance, broad-based outcome assessment including measures of real-world functioning, and others. Continued research progress will depend on greater attention to magnitude and maintenance of therapeutic change, long-term follow-up, moderators and mediators of change, and development and testing of treatment in conditions relevant to clinical practice.

Looking at the field as a whole through metaanalysis, Shadish et al concluded (based on 162 studies) that marital and family therapies were significantly more effective than no treatment and at least as effective as other forms of psychotherapy. Although these reviews and others are positive, individual studies raise many questions. For instance, based on research findings, family treatments increasingly have become standard care for patients with schizophrenia. It remains unclear what degree and type of family involvement is needed for which patients at which stage of their disorder. In the area of anxiety and depression, there are too few studies to make any strong conclusion. Although investigators such as Barrett, Cobham, and Diamond have produced some positive results, the Lewinsohn and Clark studies fail to demonstrate the added benefit of family involvement. Although Brent's study showed CBT to reduce depression faster, family therapy and supportive therapy did just as well in the long run, and family conflict was a strong risk factor for relapse. In the area of anorexia, Russell and Robins produced strong results from family interventions, whereas Geist found no difference between different types of family interventions. Family treatments for obesity have been inconsistent. In a metaanalysis of 41 studies, parental involvement did not contribute significantly to outcomes. In the Epstein study, however, which included 5- and 10-year follow-up, the results of family intervention were impressive. Although many of these studies can be cited for various methodologic flaws, the most consistent problem is that sample sizes are too small to detect difference between two or more active treatments. The most consistent findings (and most well-done, large studies) that support the efficacy of family-based interventions are done with externalizing problems. Work groups led by Patterson, Eisenstadt, Webster-Stratton, Alexander, and Henggeler all have produced impressive reductions of oppositional and antisocial behavior. Clinical programs that treat these populations without using a family-based intervention as at least a component of a treatment package are seriously ignoring the findings of contemporary intervention science. Programs of research by Henggeler, Szapocznik, and Liddle demonstrate similarly impressive results for substance abusing adolescents. Although preliminary results from the Dennis et al study suggest that various treatment approaches may benefit this population. Family interventions have had less success in reducing ADHD symptoms, yet these psychosocial treatments have been essential in reducing much of the family and school behavior problems associated with this disorder. Many investigators would agree that a combined medication and family treatment approach may be the treatment of choice for children with ADHD. In fact, many studies across various disorders suggest that patients respond best to comprehensive treatment packages, of which a family treatment is at least one component. Although the data are promising, many challenges lie ahead. Although collectively many family intervention studies exist, many disorders lack enough rigorous and large-scale investigations to make any strong conclusions. Kazdin argues that sample sizes of 150 are essential to detect significant differences between active treatments, and few of the reviewed studies include these kinds of patient numbers. Furthermore, not enough committed and sophisticated family treatment researchers have carried out some of the major studies. For example, the Brent study on depression and the Barkley study of ADHD, although testing family approaches, lacked well-developed and published treatment manuals, a demonstration of the necessary expertise to supervise these treatments, and data about training and adherence to these models. Although the absence of expertise limits investigator allegiance biases, treatment development and modification are essential for tailoring family treatments to target family processes specific to each disorder. Investigators such as Patterson and Liddle have invested great effort in rigorously dismantling the treatment process, identifying and refining essential ingredients, and repackaging more potent treatment protocols. This process has paid off well. Programmatic treatment development is needed for many disorders to address myriad questions. What are the essential disorder-specific family processes that should be targeted by interventions? Hostility, criticism, communication, attachment and autonomy, attributional sets, and behavior management are important processes of family life, but each may have more relative importance for specific disorders. With a greater understanding of these processes, treatments could be tailored to target these mechanisms more efficiently and effectively. (ABSTRACT TRUNCATED)

Thyroid hormone has a prominent role in the development and homeostasis of the central nervous system (CNS). Consequently, genes participating in thyroid hormone receptor (THR)-mediated signal transduction are prime candidates for neuropsychiatric illness susceptibility factors. Previously, we have associated exonic polymorphisms in a Xq13 thyroid receptor coactivator named HOPA with a modest increase in vulnerability to a broad spectrum of neuropsychiatric illness, including depression, psychosis, and hypothyroidism. In order to test and extend these findings, we have now examined the relationship between HOPA polymorphisms and neuropsychiatric illness in a cohort of Iowa adoptees. Consistent with our prior findings, HOPA polymorphisms were associated with an increased risk for major depression. There was suggestive evidence that the increased psychiatric morbidity in these subjects could represent epistasis, e.g., an interaction between the HOPA variant and a genetic diathesis for another psychiatric condition such as biologic parent antisocial behavior. Information about biologic parent behavior and the adoptive home environment was used to determine depressive symptoms attributable to gene-environment interaction. HOPA variant subjects continued to show significant differences in depressive symptoms when controlling for gene-environment interaction. Finally, because obesity is associated with hypothyroidism and HOPA polymorphisms are associated with hypothyroidism, we analyzed weight with respect to HOPA allele status. We found that that HOPA polymorphisms were associated with increased risk for obesity (P <.001). In summary, we conclude that HOPA polymorphisms may be a moderate risk factor for increased susceptibility to a broad spectrum of neuropsychiatric illness and hypothesize that the type of illness manifested might be related to a separate genetic diathesis.

We explored family processes in adolescence that may influence the likelihood of obesity in early adulthood using a randomized trial of a family-based intervention (the Family Check-Up, or FCU). The FCU has been shown to reduce escalations in antisocial behavior and depression in adolescence by supporting positive family management practices, but no research has examined the mechanisms by which the FCU could influence health-related attitudes and behaviors linked to obesity. Participants were 998 adolescents (n = 526 male; n = 423 European American; M age 12.21 years) and their families, recruited in 6th grade from 3 middle schools in the Pacific Northwest. We used structural equation modeling (SEM) and an Intent-To-Treat (ITT) design to evaluate the direct and indirect effects of the FCU on parent-youth relationship quality (ages 12-15), healthy lifestyle behaviors, eating attitudes, depressive symptoms (all measured at age 17), and obesity (age 22). We found that the FCU led to greater parent-youth relationship quality, which predicted enhanced health-related behaviors, reduced maladaptive eating attitudes, and reduced depression. In turn, reduced maladaptive eating attitudes predicted reduced odds of obesity. The indirect effect of the FCU on obesity by way of parent-youth relationship quality and eating attitudes was significant. Our findings illustrate how family processes may influence adolescent health and suggest that family functioning may be an additional factor to consider when developing intervention programs for obesity.

A growing body of literature is associating excessive and addictive use of digital media with physical, psychological, social and neurological adverse consequences. Research is focusing more on mobile devices use, and studies suggest that duration, content, after-dark-use, media type and the number of devices are key components determining screen time effects. Physical health effects: excessive screen time is associated with poor sleep and risk factors for cardiovascular diseases such as high blood pressure, obesity, low HDL cholesterol, poor stress regulation (high sympathetic arousal and cortisol dysregulation), and Insulin Resistance. Other physical health consequences include impaired vision and reduced bone density. Psychological effects: internalizing and externalizing behavior is related to poor sleep. Depressive symptoms and suicidal are associated to screen time induced poor sleep, digital device night use, and mobile phone dependency. ADHD-related behavior was linked to sleep problems, overall screen time, and violent and fast-paced content which activates dopamine and the reward pathways. Early and prolonged exposure to violent content is also linked to risk for antisocial behavior and decreased prosocial behavior. Psychoneurological effects: addictive screen time use decreases social coping and involves craving behavior which resembles substance dependence behavior. Brain structural changes related to cognitive control and emotional regulation are associated with digital media addictive behavior. A case study of a treatment of an ADHD diagnosed 9-year-old boy suggests screen time induced ADHD-related behavior could be inaccurately diagnosed as ADHD. Screen time reduction is effective in decreasing ADHD-related behavior.

Despite significant progress in research on the treatment and prevention of psychological, behavioral, and health problems, the translation of this knowledge into population-wide benefit remains limited. This paper reviews the state of America's children and families, highlighting the influence of stressful contextual and social conditions on child and family well-being and the concentration of disadvantage in numerous neighborhoods and communities throughout the nation. It then briefly reviews the progress that has been made in pinpointing policies that can reduce stressful contextual conditions such as poverty, discrimination, and the marketing of unhealthful foods and substances. It also describes numerous family and school interventions that have proven benefit in preventing psychological and behavioral problems as diverse as tobacco, alcohol, and other drug use; depression; antisocial behavior; academic failure; obesity prevention; and early childbearing. We argue that progress in translating existing knowledge into widespread benefit will require a nationwide effort to intervene comprehensively in neighborhoods and communities of concentrated disadvantage. We present a strategic plan for how such an effort could be organized. The first step in this organizing would be the creation of a broad and diverse coalition of organizations concerned with advancing public health and well-being. Such a coalition could increase public support both for the policies needed to focus on these disadvantaged areas and the research needed to incrementally improve our ability to help these areas.
