In the present investigation, we studied the development of 6 physically aggressive behaviors in infancy and toddlerhood, posing 3 questions (a) How do the prevalences of individual physically aggressive behaviors change from 8, 15, and 24 months? (b) Are there groups of children who show distinctive patterns in the way individual physically aggressive behaviors develop over time? (c) What are the behavioral pathways leading from 8- to 24-month acts of physical aggression? Mothers and fathers (N = 272) from a moderately at-risk population reported on their children's physical aggression at each time point. The results revealed the commonality of physical aggression at all ages studied and the diverging developmental patterns of individual behaviors. Some physically aggressive behaviors became less common (e.g., hair pulling), while others became more common (e.g., hitting), with age. Roughly 42% of the children exhibited an increased propensity, relative to their peers, to aggress at all ages. Kicking, biting, hair pulling, and pinching/scratching at 8 months were the first steps on behavioral pathways leading to physical aggression at 24 months. These pathways principally suggested heterotypic continuity in physical aggression. (PsycINFO Database Record

Past research on the relation between hostility in intimate relationships and adiposity has yielded mixed findings. The present study investigated whether the association between relationship hostility and adiposity is moderated by people's biological reactions to couple conflict. Cohabiting adult couples (N = 117 couples) engaged in two conflict interactions, before and after which salivary cortisol levels were measured. Results revealed an association between relationship hostility and adiposity, but this association was concentrated among people with relatively low levels of cortisol reactivity to couple conflict. Results are interpreted in light of research demonstrating that cortisol reactivity can become blunted over time in response to repeated stressors. These results provide precision to etiological models of obesity by identifying cortisol reactivity as a factor that moderates the association between relationship hostility and adiposity.

This phase of the NIH Science of Behavior Change program emphasizes an "experimental medicine approach to behavior change," that seeks to identify targets related to stress reactivity, self-regulation, and social processes for maximal effects on multiple health outcomes. Within this framework, our project focuses on interpersonal processes associated with health: coercive couple and parent-child conflict. Diabetes and poor oral health portend pain, distress, expense, loss of productivity, and even mortality. They share overlapping medical regimens, are driven by overlapping proximal health behaviors, and affect a wide developmental span, from early childhood to late adulthood. Coercive couple and parent-child conflict constitute potent and destructive influences on a wide range of adult and child health outcomes. Such interaction patterns give rise to disturbed environmental stress reactivity (e.g., disrupted sympathetic nervous and parasympathetic nervous systems) and a wide range of adverse health outcomes in children and adults, including dental caries, obesity, and diabetes-related metabolic markers. In this work, we seek to identify/develop/validate assays assessing coercion, identify/develop and test brief interventions to reduce coercion, and test whether changes in coercion trigger changes in health behaviors.

In the present investigation we consider and explain an apparent paradox in the measurement of corporal punishment with the Parent-Child Conflict Tactics Scale (CTS-PC): How can it have poor internal consistency and still be reliable? The CTS-PC was administered to a community sample of 453 opposite sex couples who were parents of 3- to 7-year-old children. Internal consistency was marginal, yet item response theory analyses revealed that reliability rose sharply with increasing corporal punishment, exceeding .80 in the upper ranges of the construct. The results suggest that the CTS-PC Corporal Punishment subscale reliably discriminates among parents who report average to high corporal punishment (64% of mothers and 56% of fathers in the present sample), despite low overall internal consistency. These results have straightforward implications for the use and reporting of the scale. (PsycINFO Database Record

Over 1 in 5 dental patients report moderate to severe dental fear. Although the efficacy of cognitive-behavioral treatment (CBT) for dental fear has been examined in over 20 randomized controlled trials-with 2 meta-analyses finding strong average effect sizes ( d > 1)-CBT has received almost no dissemination beyond the specialty clinics that tested it. The challenge, then, is not how to treat dental fear but how to disseminate and implement such an evidence-based treatment in a way that recognizes the rewards and barriers in the US health care system. This mixed-method study investigated the potential of disseminating CBT through care from a mental health provider from within the dental home, a practice known as evidence-based collaborative care (EBCC). Two preadoption studies were conducted with practicing dentists drawn from a self-organized Practice-Based Research Network in the New York City metropolitan area. The first comprised 3 focus groups ( N = 17), and the second involved the administration of a survey ( N = 46). Focus group participants agreed that CBT for dental fear is worthy of consideration but identified several concerns regarding its appeal, feasibility, and application in community dental practices. Survey participants indicated endorsement of factors promoting the use of EBCC as a mechanism for CBT dissemination, with no factors receiving less than 50% support. Taken together, these findings indicate that EBCC may be a useful framework through which an evidence-based treatment for dental fear treatment can be delivered.

The longitudinal course of the psychological health (PH) of United States Air Force (USAF) base communities in relation to risk and demographic factors was studied over a 5-year period. PH (clinically significant hazardous drinking, prescription drug misuse, depressive symptoms, suicidal thoughts and behaviors, intimate partner violence [IPV] and child abuse) and risk (personal and family adjustment, workplace adjustment, broader community adjustment) and demographic factors (age and gender distribution) were operationalized at the aggregate level for bases (N = 77) as measured in three large scale surveys of USAF active duty members. Bases whose members collectively exhibited greater levels of risk collectively experienced greater initial problems with alcohol and drug use, depression, suicidality, and physical IPV. Hazardous drinking more quickly increased at bases whose members were younger and more male, and at those with poorer initial aggregate personal adjustment and workplace adjustment. The challenges of studying the community-level course of PH are highlighted.

OBJECTIVE: Investigate (1) the association of child adiposity with parent-to-child and parent-to-parent hostility, (2) the mediation of these associations by dietary behaviours and (3) moderation by gender. DESIGN: One hundred thirty-five couples with 6- to 14-year-old children completed measures of emotional and physical aggression, overreactive discipline and child diet. Parent-to-parent hostility was also coded from laboratory observations. MAIN OUTCOME MEASURE: Child adiposity was a combination of body mass index and waist-to-hip ratio. RESULTS: Mother-to-child hostility was associated with child adiposity. This association was concentrated in boys and was not significantly explained by child dietary factors. Mother-to-father hostility was not significantly associated with boys' or girls' adiposity. Girls' adiposity was not significantly associated with family hostility. Fathers' hostility was not linked to child adiposity. CONCLUSION: This is the first study to take a family-level approach to understanding the relation of hostility to child adiposity by examining relations among adiposity and both mothers' and fathers' hostility directed toward one another and toward their children. Our findings highlight the potential role played by mothers' emotional hostility in boys' adiposity and suggest that, if this role is further substantiated, mother-son emotional hostility may be a promising target for the prevention of child obesity.

Military deployment can create significant relationship strain. Although most couples navigate the challenges of deployment successfully, this period may render some couples more vulnerable to adverse relationship outcomes such as infidelity due to a convergence of factors including geographic separation and reduced emotional and physical intimacy. Despite anecdotal reports of increased rates of infidelity during deployment, empirical findings are lacking. This study used a prospective design to examine the prevalence and risk factors of infidelity across the deployment cycle including a year-long deployment to Iraq. A total of 63 married male Airmen were assessed both pre- and 6-9 months postdeployment. The rate of sexual infidelity prior to deployment (21%) was commensurate with the lifetime rate of sexual involvement outside the marriage in representative community samples of men. Across the deployment period, the prevalence of sexual infidelity was strikingly high (22.6%) compared with annual community estimates (1.5-4%; Allen et al., 2005). Findings demonstrated that service members with a prior history of separation, steps toward divorce, and relationship distress prior to deployment had elevated risk for infidelity over the deployment cycle. Moreover, roughly 75% of Airmen who experienced infidelity over the deployment cycle divorced by 6-9 months postdeployment whereas only 5% of service members without infidelity divorced during this same time period. Considering well-documented adverse impacts of infidelity and divorce, the current findings may assist in identifying military couples at risk for infidelity and informing targeted prevention or early intervention strategies for these couples prior to or immediately following deployment.

Research has garnered support for a systemic view of factors affecting child dental caries that accounts for the influence of social factors such as the family environment. Our previous work has demonstrated the association between mother-to-father emotional aggression and child caries. The present study builds on these results by evaluating pathways that might explain this relation. Families (n = 135) completed a multimethod assessment of mother-to-father emotional aggression, child caries, and several hypothesized mediators (i.e., child cariogenic snack and drink intake, child internalizing behaviors, child salivary cortisol and alpha-amylase reactivity, parental laxness, child oral hygiene maintenance, and parental socialization of child oral hygiene maintenance). Mediation analyses partially supported the role of the child's diet as a mechanism linking mother-to-father emotional aggression and child caries. However, children's neglect of oral hygiene, parental laxness, and child emotional and biological disturbances failed to stand as conduits for this association. Future investigations should expand upon these results to better establish the causal links that could only be suggested by the present cross-sectional findings.
