Do Brief Lab-Based Interventions Decrease Coercive Conflict Within Couples and Parent-Child Dyads?

Coercive conflicts between parents and children and between couples are implicated in the pathogenesis of a variety of psychological and physical health problems. Despite its seeming importance to population health, there are no widely available, easy-to-use methods with demonstrated efficacy to engage coercive conflict and reduce it. Identifying and testing potentially efficacious and disseminable micro-interventions (i.e., interventions that can be delivered in under 15 minutes via computer or paraprofessional) for targets with cross-cutting health implications, such as coercive conflict, is the focus of the National Institutes of Health Science of Behavior Change initiative. We experimentally tested four micro-interventions targeting coercive conflict in couple and parent-child dyads in a within-between design. There were mixed but supportive findings for the efficacy of most of the micro-interventions. Attributional reframing, implementation intentions, and evaluative conditioning all reduced coercive conflict as assessed by some but not all measures of observed coercion. No findings indicated any iatrogenic effects. Interpretation bias modification treatment improved at least one measure of coercive conflict for couples, but not for parents and children; additionally, it increased self-reported coercive conflict. Overall, these results are encouraging and suggest that very brief and highly disseminable micro-interventions for coercive conflict are a fruitful direction for inquiry. Optimizing micro-interventions and deploying them across the health care infrastructure could tremendously enhance family functioning and, in turn, health behaviors and health (ClinicalTrials.gov IDs: NCT03163082, NCT03162822).

Demand-avoid-withdraw processes in adolescent dating aggression.

We conducted an observational study of a collection of interactive processes known as "demand-withdraw" in relation to adolescent dating aggression. Couples (N = 209) aged 14-18 years participated in a challenging observational laboratory assessment to measure demands (i.e., pressures for a change), as well as demand → partner withdraw and demand → partner avoid sequences. Actor and partner effects were disentangled via dyadic data analyses. The results indicated a fairly consistent pattern in which demand → withdraw and demand → avoid sequences led by either partner were positively associated with both partners' physical and psychological aggression (measured via a dual informant questionnaire method). Further, higher quality demands (i.e., pressures for change that were specific and encouraged both members of the dyad to increase a given behavior) were inversely associated with aggression. Yet, all of the above associations were attenuated to the point of statistical nonsignificance after controlling for hostility. These results suggest two primary possibilities. The associations of demand → withdraw and demand → avoid sequences with dating aggression may be spurious, with the sequences merely markers for hostility, a known correlate of dating aggression. Alternatively, hostility may mediate the relations of demand → withdraw and demand → avoid sequences with dating aggression. Further research is required to test these competing explanations. Implications for preventive intervention are discussed.

Does Observed Conflict Recovery Play a Role in Adolescent Dating Aggression?

In a study of conflict recovery and adolescent dating aggression, 14- to 18-year-old couples (N = 209 dyads) participated in a 1-hr observational assessment. Negative behavior was observed during conflict-evoking "hot" tasks and in a "cooldown" task. Physical and psychological dating aggression were assessed via questionnaires. Negative behavior measured in the cooldown task was not associated with dating aggression after controlling for carryover effects of negativity from the hot to cooldown tasks. Moreover, cooldown negativity moderated the associations of hot task negativity and dating aggression. Actor and partner effects were disentangled via dyadic data analyses. Given the paucity of observational studies of dating aggression, our findings are an important contribution to the literature and in need of replication and extension.

Predictors of Crosscutting Patterns of Psychological Health and Family Maltreatment.

INTRODUCTION: Psychological problems and family maltreatment are significant public health problems. Although research focuses almost exclusively on either individual psychological problems or family maltreatment, there is substantial co-occurrence of these problems. Similarly, intervention services are often "siloed": individuals with mental health needs are referred for mental health services, individuals with family conflict are referred for family-based treatment, etc. These treatment "silos" may miss the larger picture of the co-occurrence of risk, promotion, and the problems themselves. In a previous paper, we used latent class analysis to identify subgroups of individuals with crosscutting patterns (i.e., classes) of psychological and family maltreatment problems. In this study, we explored the predictors of these latent classes. MATERIALS AND METHODS: Participants consisted of two large population samples of U.S. Air Force active duty members (ns = 27,895 and 30,841) who were married or cohabiting and had one or more children living in their household. Participants completed an anonymous community assessment survey, which included questionnaire items tapping personal, family, and community problems and well-being. Assessments were conducted in 2008 and 2011. All study procedures were approved by the authors' Institutional Review Board. We used exploratory factor analysis and latent class analysis to (1) identify higher-order factors of risk and promotive variables and (2) examine them as predictors of our previously identified latent classes. RESULTS: Findings indicated that individuals who reported better physical well-being as well as personal and family coping, relationship satisfaction, and support were more likely to be in the lowest-risk subgroup. Notably, individuals in the subgroup most at risk for serious violence and suicide, evidencing disinhibitory psychopathology, endorsed lower risk and higher promotive factors than those individuals in other high-risk subgroups who fell along the internalizing/externalizing continuum. CONCLUSIONS: These findings reinforce the need for integrated prevention and treatment of psychological and family maltreatment problems. Not only do these problems often co-occur, but their risk and promotive factors also tend to be intertwined. The unique (i.e., not on the continuum of the other five classes) problem profile of participants evidencing disinhibitory psychopathology is matched by a unique risk/promotive factor profile, and they will thus likely require a unique intervention approach.

Do Fairly-Decided Maltreatment Determinations Significantly Reduce Recidivism? A Quasi-Experimental Evaluation of a System-Level Intervention Implementation.

Two studies examined the impact of the implementation of the Field-tested Assessment, Intervention-planning, and Response (FAIR) system, a system-level intervention for determining whether allegations of family maltreatment meet threshold for abuse or neglect, on alleged recidivism. Data were collected at the 10 U.S. Army installations with the largest family maltreatment caseloads. Participants were family members who had an allegation of family maltreatment (i.e., child maltreatment or partner abuse) during one of the two study periods. Data were collected when Family Advocacy Program staff used the then-in-place system (Case Review Committee) and later the FAIR system. In Study 1, cases were followed for 6 months following the initial maltreatment allegation to measure the occurrence of subsequent allegations of any type. Additionally, at five installations, alleged victims of partner abuse were recruited into a study (Study 2) in which they anonymously reported on intimate partner violence via telephone. In Study 1, the advantage for the FAIR condition was concentrated in cases with unsubstantiated initial determinations; the mean relative risk reduction for recidivism was 0.48. In Study 2, FAIR extended median time to recidivism by approximately 170%. These results replicate and extend earlier findings that employing the FAIR system can result in decreased family maltreatment re-offense.

Overlap of relationship distress and intimate partner violence in community samples.

Mixed-gender couples presenting for couple therapy are at 2-3 times higher risk for physical intimate partner violence (IPV) than community couples. However, it is unclear if this elevation of relative risk is the same in the general population because relationship distress and treatment-seeking are often confounded. We used archival data from three representative U.S. civilian samples and one representative U.S. Air Force sample to test the hypothesis that clinically significant relationship distress is associated with increased risk of various forms of IPV. In these community samples, those in mixed-gender distressed relationships were at 2-3 times higher risk than those in nondistressed relationships for any physical IPV during the past year and at 3-6 times higher risk for clinically significant psychological and physical IPV during the past year. Given that the increase in IPV risk is similar for individuals in distressed community relationships and therapy-seeking relationships, the prior findings of the elevated rates of IPV in clinical samples are unlikely to be due to therapy-seeking. Although epidemiological risk involves statistical, not causal, associations, the increased co-occurrence of IPV in distressed mixed-gender couples fits with numerous theories of IPV and has implications for both screening and future research.

Glimpsing the Iceberg: Parent-Child Physical Aggression and Abuse.

Despite evidence that parents' physical aggression abuse has long-lasting negative consequences, information about the true population prevalence of aggression and physical abuse is limited. We have even less information about how parental aggression and abuse vary by child age, parent gender, and how that aggression and abuse might be clustered within families. To address these gaps, an anonymous, computer-based assessment was administered to nearly 40,000 parents of more than 60,000 children in the United States Air Force, which included a detailed assessment on up to four minor children of aggression and its impact. The survey was the largest of its type ever conducted in the United States, allowing for stable, crossvalidated estimation of rates of both corporal punishment and physical abuse. Approximately 39% of children experienced corporal punishment, peaking at three years of age, and 7% experienced physical abuse, peaking at age six. About 45% of parents reported perpetrating corporal punishment and 8% abuse; these rates were higher in multi-child families and most often involved more than one child. Parent gender was not associated with physical aggression or abuse.

"Self-report measures of coercive process in couple and parent-child dyads": Correction.

Reports an error in "Self-report measures of coercive process in couple and parent-child dyads" by Danielle M. Mitnick, Michael F. Lorber, Amy M. Smith Slep, Richard E. Heyman, Shu Xu, Lisanne J. Bulling, Sara R. Nichols and J. Mark Eddy (Journal of Family Psychology, 2021[Apr], Vol 35[3], 388-398). In the original article, the full acknowledgment of funding was missing in the author note and should have read "This work was supported by the National Institutes of Health (NIH) Science of Behavior Change Common Fund Program and the National Institute of Dental and Craniofacial Research through an award administered by the National Institute of Dental and Craniofacial Research [1UH2DE025980-01]." The online version of this article has been corrected. (The following abstract of the original article appeared in record 2020-49926-001). One of the most influential behavioral models of family conflict is G. R. Patterson's (1982) coercive family process theory. Self-reports for behaviors related to coercion (e.g., hostility toward a family member) abound; however, there are no self-report measures for coercive process itself, which is, by definition, a dyadic process. Operationalizations of coercive process are measured with behavioral observation, typically including sequential analyzed, microcoded behaviors. Despite its objectivity and rigor, coding of behavior observation is not always feasible in research and applied settings because of the high training, personnel, and time costs the observation requires. Because coercive process has been shown to predict a host of maladaptive outcomes (e.g., parent-child conflict, aggression, negative health outcomes) and given the complete absence of self-report measures of coercive process, we recently designed brief questionnaires to assess coercive process in couple (Couple Coercive Process Scale [CCPS]) and parent-child interactions (Parent-Child Coercive Process Scale [PCCPS]) and tested them via Qualtrics participant panels in samples recruited to mirror socioeconomic generalizability to U.S. Census data. The CCPS and PCCPS exhibited initial evidence of psychometric quality in measuring coercive process in couple and parent-child dyads: Both measures are unifactorial; have evidence of reliability, especially at higher levels of coercive process; and demonstrate concurrent validity with constructs in their nomological networks, with medium to large effect sizes.

Prevention System Implementation and Reach: Attitudes and Environmental Predictors in a Randomized Controlled Trial of the NORTH STAR Prevention System.

Although many evidence-based interventions are well-established, our understanding of how to effectively implement and sustain those interventions in real-world settings is less well understood. We investigated predictors of implementation and reach in a randomized controlled trial of the NORTH STAR prevention system. One-third of U.S. Air Force (AF) bases worldwide were randomly assigned to NORTH STAR (n = 12) or an assessment-and-feedback-only condition (n = 12). Process data regarding implementation factors were collected from Community Action Team (CAT) members and observations of CAT processes. Results from a series of regression analyses indicated that change in leadership and community support, action planning processes, and perceived approach effectiveness from pre-action planning to follow-up predicted community action plan (CAP) implementation and that changes in barriers to implementation predicted CAP reach. Pre-action planning reports of CAT member self-efficacy and perceived approach effectiveness also predicted CAP implementation at 1-year follow-up. Future directions and practice recommendations are provided.

Couples' Anger Dynamics during Conflict: Interpersonal Anger Regulation, Relationship Satisfaction, and Intimate Partner Violence.

We tested hypotheses about moment-to-moment interpersonal influences on anger during couples' conflict, and the association of those anger dynamics with relationship satisfaction and intimate partner violence (IPV). Displayed anger was coded from laboratory observations of cohabiting couples (N = 197); experienced anger was assessed via a video-recall procedure. Credible, but variable, associations were found in which a person's anger display at one moment was linked to change in the partner's anger display and experience in the next moment. Women's anger experience was more strongly influenced by men's anger displays in couples with higher levels of IPV and couples with lower levels of relationship satisfaction. The displayed anger of men who perpetrated higher levels of IPV was more strongly influenced by women's anger displays. Overall, when individuals displayed higher intensity anger, partners reacted with increasingly angry feelings but decreasingly angry displays. Results suggest that anger dynamics relate to dyadic processes and that dynamics relate to important relationship outcomes. Dyadic anger dynamics might prove a worthy intervention target.

Comprobamos hipótesis acerca de las influencias interpersonales en la ira de un momento a otro durante el conflicto de las parejas y la asociación de esas dinámicas de la ira con la satisfacción con la relación y la violencia de pareja. Se codificó la ira demostrada a partir de observaciones en laboratorio de parejas convivientes ((N = 197); la ira sufrida se evaluó mediante un procedimiento de videollamada. Se hallaron asociaciones creíbles, pero variables, en las cuales la demostración de ira de una persona en un momento estuvo ligada a un cambio en la demostración y la experiencia de ira del otro integrante de la pareja al momento siguiente. La experiencia de ira de las mujeres estuvo influenciada más marcadamente por las demostraciones de ira de los hombres en las parejas con niveles más altos de violencia de pareja y en las parejas con niveles más bajos de satisfacción en la relación. La ira demostrada de los hombres que ejercían niveles más altos de violencia de pareja estuvo influenciada más marcadamente por las demostraciones de ira de las mujeres. En general, cuando las personas demostraron una ira de mayor intensidad, sus parejas reaccionaron con sentimientos de ira cada vez mayores, pero con demostraciones de ira cada vez menores. Los resultados sugieren que la dinámica de la ira se relaciona con procesos diádicos y que esa dinámica se relaciona con importantes resultados para las relaciones. La dinámica diádica de la ira podría ser un objetivo valioso de intervención.

The Impact of NORTH STAR on Suicidality, Substance Problems, Intimate Partner Violence, and Child Abuse.

INTRODUCTION: We evaluated the effectiveness of New Orientation for Reducing Threats to Health from Secretive-problems That Affect Readiness (NORTH STAR), a community assessment, planning, and action framework to reduce the prevalence of suicidality, substance problems, intimate partner violence, and child abuse. MATERIALS AND METHODS: One-third of U.S. Air Force bases worldwide were randomly assigned to NORTH STAR (n = 12) or an assessment-and-feedback-only condition (n = 12). Two Air Force-wide, cross-sectional, anonymous, web-based surveys were conducted of randomly selected samples assessing risk/protective factors and outcomes. This study was reviewed and approved by the institutional review board at the investigators' university and by the institutional review board at Fort Detrick. RESULTS: NORTH STAR, relative to control, bases experienced a 33% absolute risk reduction in hazardous drinking rates and cumulative risk, although, given the small number of bases, these effects were not statistically significant. CONCLUSIONS: Given its relatively low cost, use of empirically supported light-touch interventions, and emphasis on sustainability with existing resources, NORTH STAR may be a useful system for prevention of a range of adult behavioral health problems that are difficult to impact.

High sensitivity and specificity screening for clinically significant intimate partner violence.

The U.S. Preventive Services Task Force has recommended that clinicians screen patients for intimate partner violence (IPV). This article aims to develop and test the first screeners for clinically significant physical and psychological IPV (i.e., acts meeting criteria in the International Classification of Diseases (11th ed.; ICD-11; World Health Organization, 2019) and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013). The goal was to derive screeners that (1) are maximally brief, while still achieving high sensitivity and specificity; (2) assess perpetration and victimization when either men or women are reporting; and (3) use ICD-11/DSM-5 criteria as the reference standard. Random samples of active duty service members at 82 installations worldwide were obtained via e-mail invitation (2006: N = 54,543; 2008: N = 48,909); their response rates were excellent for long general population surveys with no payment (2006: 44.7%, 2008: 49.0%). The population of spouses at the participating installation was invited by mailed postcard (2006: N = 19,722; 2008: N = 12,127; response rates-2006: 12.3%, 2008: 10.8%). Clinically significant physical intimate partner violence can be effectively screened with as few as four items, with sensitivities > 90% and specificities > 95%; clinically significant psychological intimate partner violence can be screened with two items. Men and women can be screened with equivalent accuracy, as can those committing the violence and those victimized by it. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Self-report measures of coercive process in couple and parent-child dyads.

One of the most influential behavioral models of family conflict is G. R. Patterson's (1982) coercive family process theory. Self-reports for behaviors related to coercion (e.g., hostility toward a family member) abound; however, there are no self-report measures for coercive process itself, which is, by definition, a dyadic process.

Evaluating the Effectiveness of NORTH STAR: a Community-Based Framework to Reduce Adult Substance Misuse, Intimate Partner Violence, Child Abuse, Suicidality, and Cumulative Risk.

We evaluated the effectiveness of NORTH STAR, a community assessment, planning, and action framework to reduce the prevalence of several secretive adult problems (hazardous drinking, controlled prescription drug misuse, suicidality, and clinically significant intimate partner violence and child abuse [both emotional and physical]) as well as cumulative risk. One-third of US Air Force (AF) bases worldwide were randomly assigned to NORTH STAR (n = 12) or an assessment-and-feedback-only condition (n = 12). Two AF-wide, cross-sectional, anonymous, web-based surveys were conducted of randomly selected samples assessing risk/protective factors and outcomes. Process data regarding attitudes, context, and implementation factors were also collected from Community Action Team members. Analyzed at the level of individuals, NORTH STAR significantly reduced intimate partner emotional abuse, child physical abuse, and suicidality, at sites with supportive conditions for community prevention (i.e., moderation effects). Given its relatively low cost, use of empirically supported light-touch interventions, and emphasis on sustainability with existing resources, NORTH STAR may be a useful framework for the prevention of a range of adult behavioral health problems that are difficult to impact.

Predicting Program Retention in a Flexibly-Delivered Relationship Education Program for Low-Income, Unmarried Parents.

Participation rates in couple relationship education (CRE) programs for low-income couples are typically low. We examined predictors of session attendance and early dropout (i.e., dropout after 1 session) among a sample of low-income, unmarried parents of a newborn (N = 467 couples) enrolled in an evidence-based CRE program. Predictors included demographics and socioeconomic status, as well as baseline indicators of relationship commitment, family and individual functioning, infant health, preventive health care utilization, and CRE coach perceptions of participant engagement and alliance in the first session of the program. Couples attended an average of 4.4 (SD = 2.5) of the 7 sessions, with nearly a quarter of couples dropping out after the first session. Attendance at fewer sessions was predicted by younger age. Early dropout was predicted by lower ratings of females' engagement and both partners' therapeutic alliance and, unexpectedly, by commitment. We discuss considerations for engaging low-income couples in CRE.

Using Security Questions to Link Participants in Longitudinal Data Collection.

Anonymous data collection systems are often necessary when assessing sensitive behaviors but can pose challenges to researchers seeking to link participants over time. To assist researchers in anonymously linking participants, we outlined and tested a novel security question linking (security question linking; SEEK) method. The SEEK method includes four steps: (1) data management and standardization, (2) many-to-many matching, (3) fuzzy matching, and (4) rematching and verification. The method is demonstrated in SAS with two samples from a longitudinal study of adolescent dating violence. After an initial assessment during a laboratory visit, participants were asked to complete an online assessment either (a) once, 3 months later (Sample 1, n = 60), or (b) three times at 1-month intervals (Sample 2, n = 140). Demographics, eye color, and responses to nine security questions were used as key variables to link responses from the laboratory and online follow-up assessments. The rates of matched cases were 100% in Sample 1 and from 94.3 to 98.3% in Sample 2. To quantify the confidence in the data quality of successfully matched pairs, we reported the means and standard deviations of the number of matched security questions. In addition, we reported the rank order and counts of the mismatched components in key variables. Results indicate that the SEEK method provides a feasible and reliable solution to link responses in longitudinal studies with sensitive questions.

A Research Program Testing the Effectiveness of a Preventive Intervention for Couples with a Newborn.

Noxious family environments are associated with a wide range of adverse child outcomes. In order to prevent couple and parent-child relationship problems, a number of programs have been developed for couples with newborns. The current paper describes a program of research evaluating the American version of couple CARE for parents of newborns. This version of CCP was administered to low-income, unmarried couples with a new baby in an uncontrolled demonstration project (Study 1), compared with a waitlist control condition in a randomized controlled trial (Study 2), and evaluated with low-income parents recruited from urban hospitals in two major metropolitan areas of the United States (Study 3 and Study 4). Despite participant satisfaction with CCP, preventive effects of the program were limited and there was one potential iatrogenic effect. Results were likely impacted by major challenges with recruiting participants and maintaining their engagement in CCP for the duration of the program. We discuss methodological differences between this series of studies and previous trials of prevention programs and make recommendations for improving service delivery to at-risk new parents. These results have implications for public policies that aim to benefit children and families.

Los latinos de bajos recursos están expuestos a amplias desigualdades relacionadas con la salud mental en los Estados Unidos. Recientemente, un resurgimiento de relatos antiinmigratorios han llevado a los inmigrantes latinos vulnerables a sufrir considerables factores desencadenantes de estrés contextual con varias consecuencias perjudiciales para su bienestar general, por ejemplo, interrupciones significativas a sus prácticas de crianza. Dentro de este contexto de adversidad, y a pesar de los múltiples beneficios asociados con las intervenciones preventivas de capacitación para padres, la disponibilidad de intervenciones de capacitación para padres contextualmente y culturalmente relevantes siguen siendo limitadas en las comunidades latinas marginadas. Este artículo constituye un aporte a este déficit de conocimiento mediante la presentación de un modelo de aplicación de intervenciones utilizado en la difusión de versiones culturalmente adaptadas de la intervención de base factual, conocida como GenerationPMTO.© El modelo propuesto también describe un proceso de cambio que hemos documentado en la investigación empírica con padres inmigrantes latinos de bajos recursos que han estado expuestos a las intervenciones adaptadas. El manuscrito está organizado en cuatro secciones. Primero, se debate una presentación general del modelo junto con un breve resumen de teorías principales. Luego, se describen los componentes principales del modelo, complementados por la presentación de un caso práctico. Finalmente, se debaten las consecuencias para la prevención y la intervención clínica.

The Impact of a Preventive Intervention on Persistent, Cross-Situational Early Onset Externalizing Problems.

The Nurse-Family Partnership (NFP) home visiting intervention for low-income first-time mothers was evaluated for its preventive impact on persistent, cross-situational early-onset externalizing problems (EXT). Seven hundred thirty-five women in the Denver, CO, area were randomly assigned into one of two active conditions (nurse or paraprofessional home visiting from pregnancy through child age 2) or a control group in which children were screened and referred for behavioral and developmental problems. Externalizing behavior was assessed by parent report when the children were 2, 4, 6, and 9 years old; teachers provided reports at ages 6 and 9. Latent profile analyses suggested the presence of persistent, cross-situational early onset EXT in approximately 6 to 7% of girls and boys. The intervention deflected girls away from these EXT and toward a pattern marked by a persistent moderate elevation of externalizing behavior that was evident at home and not at school. This finding should be interpreted cautiously given the small number of girls with the elevated EXT. Surprisingly, the intervention also moved girls away from stable low level externalizing behavior toward the moderately elevated pattern. Both of the significant effects on girls' externalizing behavior were modest. No statistically significant effects were found for boys' externalizing behaviors, which exhibited a somewhat different patterning across time and reporter. Effect sizes were generally similar for the nurse and paraprofessional-visited groups. The results are discussed in the context of prior efforts to prevent early EXT and emerging evidence on the normative development of externalizing behavior.

Normative Trends in Physically Aggressive Behavior: Age-Aggression Curves from 6 to 24 Months.

OBJECTIVE: To investigate age-related trends in physically aggressive behaviors in children before age 2 years. STUDY DESIGN: A normative US sample of 477 mothers of 6- to 24-month-old children reported on the frequency of 9 interpersonally directed aggressive child behaviors, and hurting animals, in the past month. RESULTS: Almost all (94%) of the children were reported to have engaged in physically aggressive behavior in the past month. Based on 2-part regression models, the prevalences of kicking (OR, 1.70; P = .023), pushing (OR, 3.22; P < .001), and swiping (OR, 1.78; P = .018) increased with years of age, but the prevalence of hair pulling decreased with age (OR, 0.55; P = .020). The prevalences of hitting and throwing increased initially, then plateaued at age 18-20 months, and then decreased (quadratic aOR, 0.13 and 0.16; P < .001 and .010, respectively). The frequencies of hitting (R2 = .05; P < .001) and throwing (R2 = .03; P = .030) increased, and the frequencies of hair pulling (R2 = .07; P < .001) and scratching (R2 = .02; P = .042) decreased with age (P values adjusted for false discovery rate). CONCLUSIONS: Physically aggressive behavior in the 6- to 24-month age range appears to be nearly ubiquitous. Most, but not all, forms of physical aggression increase with age. These results can guide pediatricians as they educate and counsel parents about their child's behavior in the first 2 years of life.

A Randomized, Controlled Trial of the Impact of the Couple CARE for Parents of Newborns Program on the Prevention of Intimate Partner Violence and Relationship Problems.

Effective, accessible prevention programs are needed for adults at heightened risk for intimate partner violence (IPV). This parallel group randomized controlled trial examines whether such couples receiving the American version of Couple CARE for Parents of Newborns (CCP; Halford et al. 2009) following the birth of a child, compared with controls, report fewer first occurrences of clinically significant IPV, less frequent physical and psychological IPV, and improved relationship functioning. Further, we test whether intervention effects are moderated by level of risk for IPV. Couples at elevated risk for IPV (N = 368) recruited from maternity units were randomized to CCP (n = 188) or a 24-month waitlist (n = 180) and completed measures of IPV and relationship functioning at baseline, post-program (when child was 8 months old), and two follow-ups (at 15 and 24 months). Intervention effects were tested using intent to treat (ITT) as well as complier average causal effect (CACE; Jo and Muthén 2001) structural equation models. CCP did not significantly prevent clinically significant IPV nor were there significant main effects of CCP on clinically significant IPV, frequency of IPV, or most relationship outcomes in the CACE or ITT analyses. Risk moderated the effect of CCP on male-to-female physical IPV at post-program, with couples with a planned pregnancy declining, but those with unplanned pregnancies increasing. This study adds to previous findings that prevention programs for at-risk couples are not often effective and may even be iatrogenic for some couples.
