The correlates of dyadic synchrony in high-risk, low-income toddler boys

Synchrony has been broadly conceptualized as the quality of the parent-child dyadic relationship. Parenting, factors that compromise caregiving quality, and child characteristics have all been theoretically linked to synchrony, but little research has been conducted to validate such associations. The present study examined correlates of synchrony including parenting, maternal psychological resources and child attributes, among a sample of 120 mother-son dyads who were participating in a treatment study for children identified as being at risk for developing early conduct problems. There families participated in an at-home assessment, which included a series of mother-son interactions. Synchrony was associated with aspects of parenting and child attributes, including maternal nurturance, and child emotional negativity and language skills. The findings are discussed in terms of parent and child contributions to the development of synchrony.     

Neighborhood disadvantage, parent-child conflict, neighborhood peer relationships, and early antisocial behavior problem trajectories

This study examined relations among neighborhood disadvantage, parent-child conflict, deviant peer involvement in the neighborhood, and early-starting antisocial trajectories. Antisocial group patterns were identified in 218 low-income boys followed from ages 5 to 11, and neighborhood and family variables were evaluated as predictors in early and middle childhood. Four trajectory groups emerged: one increasing pattern that corresponded with developmental theories of early-starting antisocial behavior; one with initially high and decreasing problems over time; and two low antisocial groups. Parent-child conflict and neighborhood disadvantage were significantly associated with trajectory patterns, with youth in the 2 higher antisocial behavior groups characterized by more neighborhood problems and parent-child conflict than other groups. The results suggest that in early childhood, neighborhood disadvantage and family conflict place children at risk for early-starting trajectories, and that involvement with deviant peers in the neighborhood takes on an increasingly important role in patterns of antisocial behavior over middle childhood.     

A meta-analytic review of obesity prevention programs for children and adolescents: the skinny on interventions that work

This meta-analytic review summarizes obesity prevention programs and their effects and investigates participant, intervention, delivery, and design features associated with larger effects. A literature search identified 64 prevention programs seeking to produce weight gain prevention effects, of which 21% produced significant prevention effects that were typically pre- to post effects. Larger effects emerged for programs that targeted children and adolescents (vs. preadolescents) and females, programs that were relatively brief, programs that solely targeted weight control versus other health behaviors (e.g., smoking), programs evaluated in pilot trials, and programs wherein participants must have self-selected into the intervention. Other factors, including mandated improvements in diet and exercise, sedentary behavior reduction, delivery by trained interventionists, and parental involvement, were not associated with significantly larger effects.     

College students with previous exposure to crime report more PTSD after 9-11-2001

A sample of 415 university students (52 Crime Victims, 363 Nonvictims) who experienced indirectly the 9/11/01 disaster through media exposure, were administered the Davidson Trauma Scale. Crime victims had significantly more PTSD symptoms related to 9/11 exposure.     

Responses to the September 11, 2001, terrorist attacks: experience of an indirect traumatic event and its relationship with perceived benefits

Little is known about how people might benefit from an indirectly experienced traumatic event. The authors examined the relationship between perception of benefit and trauma symptoms in response to a relatively severe, but indirectly experienced, traumatic event. The authors sampled from 2 colleges located in the southeastern United States (N = 136). Individuals responded to questionnaires that assessed perceived benefits and trauma symptoms 1-2 weeks after the terrorist attacks of September 11, 2001, and again approximately 10 weeks later. Participants did perceive benefits from witnessing this event, although their perception of benefit declined over time. Level of trauma symptoms correlated positively with perception of benefit, and experiencing a previous trauma also correlated positively with perceived benefits. Additional analysis indicated that level of trauma symptoms mediated the relationship between previous trauma and perception of benefit. These findings help to elucidate understanding of the development of perceived benefits in response to indirectly experienced events.     

Effects of reinforcement schedule on facilitation of operant extinction by chlordiazepoxide

Learning and memory are central topics in behavioral neuroscience, and inbred mice strains are widely investigated. However, operant conditioning techniques are not as extensively used in this field as they should be, given the effectiveness of the methodology of the experimental analysis of behavior. In the present study, male C57B1/6 mice, widely used as background for transgenic studies, were trained to lever press on discrete-trial fixed-ratio 5 or fixed-interval (11 s or 31 s) schedules of food reinforcement and then exposed to 15 extinction sessions following vehicle or chlordiazepoxide injections (15 mg/kg i.p., administered either prior to all extinction sessions, or prior to the final 10 extinction sessions). Extinction of operant behavior was facilitated by drug administration following training on either schedule, but this facilitation only occurred once a number of extinction sessions had taken place. The extinction process proceeded more rapidly following fixed-interval training. Resistance to extinction was equally high following training with either schedule type, and was reduced by drug administration in both cases. These phenomena were evident in individual cumulative records and in analyses of group data. Results are interpreted in terms of phenomena of operant extinction identified in Skinner's (1938) Behavior of Organisms, and by behavioral momentum theory. These procedures could be used to extend the contribution of operant conditioning to contemporary behavioral neuroscience.     

Risk Factors for Community Violence Exposure in Adolescence

Community violence is recognized a significant public health problem. However, only a paucity of research has examined risk factors for community violence exposure across domains relevant to adolescents or using longitudinal data. This study examined youth aggressive behavior in relation to community violence exposure among a community epidemiologically defined sample of 582 (45% female) urban adolescents. Internalizing behaviors, deviant peer affiliation, and parental monitoring were examined as moderators of the association between aggressive behavior and exposure to community violence. For males with aggressive behavior problems and deviant peer affiliation or low parental monitoring, co-occurring anxiety symptoms protected against subsequent witnessing community violence. In contrast, males with aggressive behavior problems and co-occurring depressive symptoms were at increased risk for witnessing community violence. Implications of the findings for preventive interventions and future research are discussed.     

Impact of a System of Care on a Community's Children's Social Services System

Researchers and practitioners have questioned how the implementation of a system of care influences the broader context of children's social services within a community. We examined the impact that the Dawn Project system of care had on children's services in Marion County, Indiana. A series of semi-structured interviews were conducted in order to gain a broad understanding of stakeholder perspectives related to how system-level and other community leaders viewed system of care influences. Qualitative analyses uncovered several common themes including positive impact at the community level, challenges to implementation, and feelings of ambivalence related to program impact. Results were generally positive and suggested that most respondents saw core system of care principles beginning to emerge within the community related to the establishment of the care system. In addition, challenges to implementing the system of care also were uncovered, including some underlying resistance to system-level changes. Implications from our study highlight the importance of continuously working to enhance strengths and collaboration among systems, integrate and coordinate across systems and services, and authentically involve families at all levels.     

Racial reckoning,resistance, and the revolution: A call to community psychology to move forward

This article introduces a special issue of the American Journal of Community Psychology that features racial reckoning, resistance and the revolution in the context of a syndemic, the historical subjugation of communities of Color (COC) to racial hierarchies and the coronavirus (COVID-19). More specifically, this special issue underscores the need for community psychology and other allied disciplines to address this syndemic facing COC. The special issue delivers on the stories of the lived experiences from researchers and community members as it relates to COVID-19 and COC. Twelve articles are illuminated to challenge the field to create social change.
