What works for whom? Mother's psychological distress as a moderator of the effectiveness of a home visiting intervention.

Attachment-based home visiting programs that serve new mothers experiencing psychological distress may advance health equity by helping families systemically exposed to adversity. This study examined whether one such program (Promoting First Relationships/PFR) had particularly beneficial effects on maternal and child relationship outcomes for mothers reporting the greatest psychological distress. A randomized controlled trial of the PFR program included a low-income sample of 252 Spanish- and English-speaking mother-child dyads referred prenatally for mental health concerns. The sample of mothers was 65.5% White, 17.5% Black, and 17.1% multiracial or other racial groups; 47.2% reported Hispanic ethnicity. The moderating variable of psychological distress was measured using maternal-reported screening tools for symptoms of depression, anxiety, anger, post-traumatic stress, and interpersonal sensitivity. Outcomes included observed parenting sensitivity and self-reported understanding of infants/toddlers, caregiving confidence, and child externalizing behavior. Results showed a significant treatment condition by baseline psychological distress interaction for observed parenting sensitivity such that differences in outcomes favoring the PFR condition were greatest among those with high baseline psychological distress (baseline child age 6-12 weeks). In a low-income sample of new mothers, those with the greatest need, as indicated by high psychological distress, showed greater improvements in their sensitive and responsive caregiving if they were randomized to the PFR treatment condition.

Los programas de visita a casa basados en la afectividad que sirven a madres nuevas que experimentan angustia sicológica pudieran mejorar la equidad de salud ayudando a familias sistemáticamente expuestas a circunstancias adversas. Este estudio examinó si uno de tales programas (Promover Primeras Relaciones /PFR) tiene particularmente efectos beneficiosos en los resultados de la relación materna y del niño para madres que reportan la mayor angustia sicológica. Un ensayo controlado al azar sobre el programa PFR incluyó un grupo muestra de bajos recursos económicos de 252 díadas de madre-niño que hablaban español o inglés, referidas prenatalmente por razón de salud mental. El grupo muestra de madres estaba compuesto de 65.5% blancas, 17.5% negras, y 17.1% multirracial o de otros grupos raciales; el 47.2% reportó origen étnico hispano. La variable moderadora de angustia sicológica se midió con herramientas de detección reportadas por las madres para síntomas de depresión, ansiedad, ira, estrés postraumático y sensibilidad interpersonal. Entre los resultados se incluyen la observada sensibilidad de crianza y la auto-reportada comprensión de infantes y niños pequeñitos, la confianza en la prestación de cuidado, así como la conducta de externalización del niño. Los resultados muestran una significativa condición de tratamiento por medio de interacción de angustia sicológica al nivel básico para la observada sensibilidad de crianza, de manera que las diferencias en resultados que favorecen la condición PFR fueron mayores entre quienes presentaban una alta angustia sicológica de base (punto base edad del niño 6 a 12 semanas). En un grupo muestra de madres nuevas de bajos recursos económicos, aquellas con las mayores necesidades, tal como indica la alta angustia sicológica, mostraron mayores logros en su sensibilidad y el cuidado sensible si se les había seleccionado al azar para la condición de tratamiento PFR.

Les programmes de visite à domicile basés sur l'attachement qui servant des nouvelles mères faisant l'expérience de détresse psychologique peuvent faire avancer l'équité en santé en aidant des familles systématiquement exposées à l'adversité. Cette étude a examiné si un tel programme (la Promotion de Premières Relations, soit en anglais Promoting First Relationships/PFR) avait des effets particulièrement bénéfiques sur les résultats de relation maternelle et enfant pour les mères faisant état de la plus grande détresse psychologique. Un essai contrôlé randomisé du programme PFR a inclus un échantillon de 252 dyades mères-enfants de milieu défavorisé, parlant espagnol et anglais, référées avant la naissance pour des problèmes de santé mentale. L'échantillon de mères était 65,5% caucasiennes/blanches, 17,5% noires, and 17,1% multiraciales ou autres groupes raciaux, 47,2% faisant état d'une ethnicité hispanique. La variable modératrice de détresse psychologique a été mesurée en utilisant des outils de dépistage rapportés par la mère de dépression, d'anxiété, de stress post-traumatique, et de sensibilité interpersonnelle. Les résultats ont inclus une sensibilité de parentage observée et une compréhension auto-rapportée des bébés/petits enfants, une confiance de parentage, et un comportement externalisant de l'enfant. Les résultats montrent une condition de traitement importante par l'interaction psychologique de base pour la sensibilité de parentage observée telles que les différences dans les résultats favorisant la condition PFR étaient les plus grandes parmi celles avec la base de détresse psychologique élevée (âge de base de l'enfant 6-12 semaines). Chez un échantillon de nouvelles mères de milieux défavorisés, celles ayant le besoin le plus élevé, indiqué par une haute détresse psychologique, ont fait preuve des plus améliorations dans leur parentage sensible et réactif si elles étaient randomisées pour la condition de traitement PFR.

Early Life Adversity and Pubertal Timing: Implications for Cardiometabolic Health.

OBJECTIVE: To identify early life adversity (ELA) risk factors for earlier pubertal timing, itself a risk factor for poor cardiometabolic health, and to determine whether such ELA-related risk may be mediated by pre-pubertal body mass index (BMI). METHODS: Subjects included 426 female participants in a prospective birth cohort study, the NICHD Study of Early Child Care and Youth Development. Survival analysis models were fit to examine ELA exposures, representing childhood socioeconomic status (SES), maternal sensitivity, mother-child attachment, and negative life events, along with child health indicators and covariates, in relation to pubertal timing outcomes, including age at menarche and ages at Tanner stage II for breast and pubic hair development. RESULTS: Higher childhood SES emerged as an independent predictor of older age at menarche, showing each one standard deviation increase in childhood SES corresponded to a 1.3% increase in age at menarche (factor change = 1.013; 1.003-1.022; p < .01), but did not predict breast or pubic hair development (ps > .05). In mediation analyses, indirect (mediated) effects of mother-child attachment on the pubertal timing outcomes, via pre-pubertal BMI, were all statistically significant (ps < .05). CONCLUSIONS: Higher childhood SES predicted directly, and secure (vs. insecure) mother-child attachment predicted indirectly (via pre-pubertal BMI), later pubertal timing, suggesting these factors may protect girls from earlier pubertal development. By extension, clinical implications are that intervention strategies designed to lessen ELA- and pre-pubertal obesity-related risk may be effective in remediating life course pathways linking ELA, accelerated pubertal development, and cardiometabolic risk.

Sleep Problems, Daily Napping Behavior, and Social-Emotional Functioning among Young Children from Families Referred to Child Protective Services.

OBJECTIVE/BACKGROUND: Insufficient and/or poor-quality sleep may contribute to poor social-emotional well-being, and vice versa, among young children who have experienced maltreatment. This study examined longitudinal associations between sleep and social-emotional functioning among a sample of infants and toddlers from families involved with Child Protective Services (CPS) for maltreatment. PARTICIPANTS: Participants were 123 parents and their infant or toddler (baseline age 10 to 24 months) from families referred to CPS for maltreatment. METHODS: Data were collected at baseline and at 3, 6 and 9 months post-baseline. At all time points, parents completed a questionnaire about their child's social-emotional functioning including internalizing behavior, externalizing behavior, and competence in social-emotional skills and social relatedness. At 3 months post-baseline, parents reported about their child's sleep problems and daily napping behavior. RESULTS: Higher baseline externalizing behavior was associated with a greater propensity for sleep problems at 3 months post-baseline. Sleep problems at 3 months post-baseline were associated with higher internalizing and higher externalizing behavior at 9 months post-baseline. Daily napping at 3 months post-baseline was associated with lower internalizing behavior, lower externalizing behavior, and higher competence at 9 months post-baseline. CONCLUSIONS: Among this sample of young children from families involved with CPS for maltreatment, parents' concerns about their child having a sleep problem longitudinally associated with children's internalizing and externalizing behavior. Children's daily napping behavior longitudinally associated with later internalizing behavior, externalizing behavior, and competence.

Sleep Patterns, Problems and Ecology among Toddlers in Families with a Child Protective Services Maltreatment Referral.

PURPOSE: To describe sleep patterns, problems, and ecology among toddlers (13 to 36 months) from families referred to Child Protective Services (CPS) for maltreatment and to compare sleep duration among a subgroup (24- to 36-month-olds) to previously published population-based data. DESIGN AND METHODS: A secondary analysis of a larger longitudinal study was conducted. Participants included 113 parent-toddler dyads recruited out of CPS offices based on having a recent maltreatment referral. Parents reported about their toddler's sleep at two time points (approximately six months apart). RESULTS: At the earlier and later time points, respectively, mean sleep duration was 11.03 and 10.90 h (nighttime), 1.36 and 1.36 h (daytime), and 12.47 and 12.28 h (total 24-h). Of the toddlers, 24% and 17% had two or more nighttime awakenings, 34% and 33% had at least a somewhat hard time falling asleep, and 25% and 26% had difficulty sleeping alone. Mean bedtimes were 8:50 pm and 8:58 pm. Nighttime sleeping arrangement/location, nap arrangement/location, and method of falling asleep at night varied. Compared to the population-based data, nighttime sleep duration was 43 min longer and nap duration was 46 min shorter in the CPS sample. CONCLUSIONS: Symptoms of behavioral sleep problems were common in this sample of toddlers from families referred to CPS for maltreatment. Distribution of sleep, but not total 24-hour sleep, differed significantly between the CPS sample and the population-based data. PRACTICE IMPLICATIONS: Nurses caring for toddlers from families involved with CPS can play an integral role promoting sleep health and addressing behavioral sleep problems.

Ensuring Implementation Fidelity of a 10-Week Home Visiting Program in Two Randomized Clinical Trials.

Introduction Implementation fidelity is a challenge for the adoption of evidence-based programs within social service broadly and child welfare specifically. However, implementation fidelity is critical for maintaining the integrity of clinical trials and for ensuring successful delivery of services in public health settings. Methods Promoting First Relationships ® (PFR), a 10-week home visiting parenting intervention, was evaluated in two randomized clinical trials with populations of families in child welfare. Seven providers from community agencies participated in the trials and administered PFR. Fidelity data collected included observational measures of provider behavior, provider records, and input from clients to assess training uptake, adherence to content, quality of delivery, program dosage, and participant satisfaction. Results In mock cases to assess training uptake, providers demonstrated an increase in PFR verbalization strategies and a decrease non-PFR verbalizations from pre to post PFR training, and overall this was maintained a year later (Mann-Whitney U's = 0, p's < .01). Adherence to content in actual cases was high, with M = 97% of the program elements completed. Quality of delivery varied across providers, indicated by PFR consultation strategies (Wilks' Lambda F = 18.24, df = 15, p < .001) and global ratings (F = 13.35, df = 5, p < .001). Program dosage was high in both trials (71 and 86% receiving 10 sessions), and participant satisfaction was high (M = 3.9, SD = 0.2; 4 = greater satisfaction). Discussion This system of training and monitoring provides an example of procedures that can be used effectively to achieve implementation fidelity with evidence-based programs in social service practice.

DYNAMIC-MATURATIONAL MODEL OF ATTACHMENT AND ADAPTATION VERSUS ABC+D ASSESSMENTS OF ATTACHMENT IN CHILD PROTECTION AND TREATMENT: REPLY TO VAN IJZENDOORN, BAKERMANS, STEELE, & GRANQVIST (2018).

In this brief response, we commend the commentary authors for joining a dialogue about the future of individual differences in attachment both around person-specific forensic and clinical issues also around working together to develop theory and coding practices. We point to several areas of explicit and implicit agreement and discuss several misunderstandings. We close with a proposal for future work together, possibly using the only set of video-recorded Strange Situations classified by Mary Ainsworth as a starting point from which we can explore alternative means of extending and expanding her work.

CAN ATTACHMENT INFORM DECISION-MAKING IN CHILD PROTECTION AND FORENSIC SETTINGS?

The historic publication of the "consensus statement" on not using the "D/disorganized" category in the infant Strange Situation (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978) for case-specific child protection work (P. Granqvist et al., 2017) opens the door for a broader discussion of different branches of attachment theory and different attachment classificatory systems applied to infants, young children, and their parents. We agree with the consensus authors that Strange Situation classifications alone, regardless of coding method, are insufficient for decision-making. The authors, however, have acknowledged that the Dynamic-Maturational Model of Attachment and Adaptation (DMM; Crittenden, 2016) offers a different perspective on classifying Strange Situations. The DMM is a branch of attachment theory that expands the Ainsworth A and C classifications across the life span to reflect the complex attachment strategies that some individuals use in dangerous contexts. We contrast the DMM to the D classification, both for the Strange Situation for infants and its adaptation for young children and also for the Adult Attachment Interview (AAI; C. George, N. Kaplan, & M. Main, 1984-1996) for their parents. We initiate a scientific dialogue by addressing three points: (a) "Attachment" does not imply or require a model that includes a D/disorganization category nor is the D/disorganized category the only clinical expansion of Mary Ainsworth's (1978) original work; (b) the DMM method for classifying Strange Situations may be better attuned to parental inadequacy and child protection than is the D/disorganized category; and (c) with attention to guidelines, DMM classifications from the Strange Situation with both infants and preschool-aged children can be used in a case-specific manner in both treatment and forensic settings. The same is true for other DMM assessments of attachment, including the AAI. We close by suggesting steps that could further understanding and application of Ainsworth's great accomplishment: individual differences in attachment relationships.

PARENTAL CHILDHOOD ADVERSITY, DEPRESSIVE SYMPTOMS, AND PARENTING QUALITY: EFFECTS ON TODDLER SELF-REGULATION IN CHILD WELFARE SERVICES INVOLVED FAMILIES.

Parents who are involved with child welfare services (CWSI) often have a history of childhood adversity and depressive symptoms. Both affect parenting quality, which in turn influences child adaptive functioning. We tested a model of the relations between parental depression and child regulatory outcomes first proposed by K. Lyons-Ruth, R. Wolfe, A. Lyubchik, and R. Steingard (2002). We hypothesized that both parental depression and parenting quality mediate the effects of parental early adversity on offspring regulatory outcomes. Participants were 123 CWSI parents and their toddlers assessed three times over a period of 6 months. At Time 1, parents reported on their childhood adversity and current depressive symptoms. At Time 2, parents' sensitivity to their child's distress and nondistress cues was rated from a videotaped teaching task. At Time 3, observers rated children's emotional regulation, orientation/engagement, and secure base behavior. The results of a path model partly supported the hypotheses. Parent childhood adversity was associated with current depressive symptoms, which in turn related to parent sensitivity to child distress, but not nondistress. Sensitivity to distress also predicted secure base behavior. Depression directly predicted orientation/engagement, also predicted by sensitivity to nondistress. Sensitivity to distress predicted emotion regulation and orientation/engagement. Results are discussed in terms of intervention approaches for CWSI families.

Disorganized attachment in infancy: a review of the phenomenon and its implications for clinicians and policy-makers.

Disorganized/Disoriented (D) attachment has seen widespread interest from policy makers, practitioners, and clinicians in recent years. However, some of this interest seems to have been based on some false assumptions that (1) attachment measures can be used as definitive assessments of the individual in forensic/child protection settings and that disorganized attachment (2) reliably indicates child maltreatment, (3) is a strong predictor of pathology, and (4) represents a fixed or static "trait" of the child, impervious to development or help. This paper summarizes the evidence showing that these four assumptions are false and misleading. The paper reviews what is known about disorganized infant attachment and clarifies the implications of the classification for clinical and welfare practice with children. In particular, the difference between disorganized attachment and attachment disorder is examined, and a strong case is made for the value of attachment theory for supportive work with families and for the development and evaluation of evidence-based caregiving interventions.

Promoting Birth Parents' Relationships with their Toddlers upon Reunification: Results from Promoting First Relationships® Home Visiting Program.

Birth parents, once reunified with their child after a foster care placement, are in need of in-home support services to prevent reoccurrence of maltreatment and reentry into foster care, establish a strong relationship with their child, and enhance child well-being. Few studies have addressed the efficacy of home visiting services for reunified birth parents of toddlers. This study reports on the findings from a randomized control trial of a 10-week home visiting program, Promoting First Relationships® (Kelly, Sandoval, Zuckerman, & Buehlman, 2008), for a subsample of 43 reunified birth parents that were part of the larger trial. We describe how the elements of the intervention align with the needs of parents and children in child welfare. Although the sample size was small and most of the estimates of intervention effects were not statistically significant, the effect sizes and the pattern of results suggest that the intervention may have improved both observed parenting sensitivity and observed child behaviors as well as decreased parent report of child behavior problems. Implications are that providing in-home services soon after a reunification may be efficacious in strengthening birth parents' capacity to respond sensitively to their children as well as improving child social and emotional outcomes and well-being.

Parenting and Preschool Self-Regulation as Predictors of Social Emotional Competence in 1st Grade.

The current longitudinal study used data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) to examine a model of development that emphasizes early caregiving environments as predictors of social emotional competence (including classroom competence). This path analysis model included features of parenting, emotion regulation, preschool language skills, and attention to predict child outcomes in 1st grade. Early caregiving environments were directly predictive of peer relationship satisfaction, oppositional behavior, social skills, and classroom competence over and above significant mediated effects through preschool self regulation (language, inattention, and anger/frustration). These results suggest that the characteristics of supportive and stimulating caregiving shift in valence over time, such that qualities of the infant-child relationship that are significant in predicting early childhood outcomes are not the same as the caregiving qualities that move to the foreground in predicting primary school outcomes. Implications for school-readiness programming are discussed, including interventions in the early caregiving system to encourage sensitive and supportive parent child interactions to bolster school readiness via the development of social-emotional competence.

An Examination of Changes in Emotion Co-Regulation Among Mother and Child Dyads During the Strange Situation.

The present study applied State Space Grid analysis to describe how preschooler-mother dyads co-regulate emotion in the Strange Situation. Second-to-second mother and child affect during pre-separation play (baseline) and the final reunion (post perturbation) episodes of the Strange Situation were coded for 80 dyads. Change in emotion co-regulation across the two Strange Situation episodes was examined with linear mixed models for groups with secure and insecure classifications. The groups did not differ at baseline. Change in content-specific emotion co-regulation but not content-free emotion co-regulation was found to be significantly different within and between groups. Both secure and insecure dyads reduced the time spent in positive interaction but increased the time in negative interaction across two episodes; the change in secure dyads was less pronounced than in the insecure dyads. After the separation, secure dyads had more positive interactions and fewer negative interactions compared to insecure dyads. Results highlight how secure dyads adapted to the stressful change, whereas insecure dyads were more reactive and less resilient to the stress of the study's brief imposed separation.

Planning in middle childhood: early predictors and later outcomes.

Data from 1,364 children and families who participated in the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development were analyzed to track the early correlates and later academic outcomes of planning during middle childhood. Maternal education, through its effect on parenting quality when children were 54 months old, predicts their concurrent performance on sustained attention, inhibition, and short-term verbal memory tests. This performance predicts planning in first grade, which predicts third-grade reading and mathematics attainment, but not the rate of growth in academic skills from first to fifth grades. This path was also found when the same parenting, cognitive, and academic constructs were measured at later time points.

The longitudinal link between parenting and child aggression: the moderating effect of attachment security.

This study examined whether infant attachment security moderates the association between parenting in preschool and later aggressive behavior among a sample of children at high risk for developing conduct problems. Participants were 82 adolescent mother-child dyads recruited from the community. Infant attachment status at age 1 year was measured using the Strange Situation. When children were aged 4.5 years, mothers reported on their self-efficacy in regards to parenting, and mothers' positive parenting and criticism were coded from direct observations of parent-child interactions. In grade 1, mothers reported on their children's aggressive behavior. Infant secure attachment significantly moderated the association between observed maternal criticism and child aggression. That is, among insecurely attached children, higher levels of maternal criticism were associated with more severe aggression. This longitudinal finding suggests that a secure attachment may buffer the deleterious effects of harsh parenting on child aggression.

Permanency Outcomes for Toddlers in Child Welfare Two Years After a Randomized Trial of a Parenting Intervention.

This study reports on child welfare outcomes of a community based, randomized control trial of Promoting First Relationships® (PFR; Kelly, Sandoval, Zuckerman, & Buehlman, 2008), a 10-week relationship-based home visiting program, on stability of children's placements and permanency status two years after enrollment into the study. Toddlers 10 - 24 months (N = 210) with a recent placement disruption were randomized, along with their birth or foster/kin parents, to PFR (n = 105) or a comparison condition (n = 105). A stable placement had no interruptions or disruptions. A permanent placement was a stable placement ending with a legal discharge to the study caregiver. Logistic regression models predicting the dichotomous stability and permanency variables, controlling for caregiver type, child welfare variables, and caregiver commitment, were conducted. There was no difference by intervention group on stability or permanency, but there was a significant interaction between caregiver type (birth parent vs. foster/kin) and intervention group. More foster/kin caregivers who received the PFR intervention provided stable, uninterrupted care and eventually adopted or became the legal guardians of the toddlers in their care, compared to foster/kin caregivers randomized to the comparison condition.

Trying to Do What's Best: Maternal Perspectives About Toddler Sleep Health Among an Underresourced Sample of Mothers With Diverse Racial and Ethnic Identities.

INTRODUCTION: This study describes mothers' knowledge, attitudes, beliefs, and practices about their toddler's sleep health among an underresourced sample of mothers with diverse racial and ethnic identities. METHOD: This was a descriptive qualitative study with 16 mothers and their 12- to 36-month-old child. Mothers completed a semistructured, audio-recorded interview about their toddler's sleep health. Data were analyzed using inductive content analysis on the basis of established methods. RESULTS: Mothers self-identified as 18.8% Black, 43.8% White, 12.5% multiracial, 25.0% other race, and 37.5% Hispanic. Of the mothers, 80.0% reported a past year household income of ≤ $40,000. A core construct, "Trying to do What's Best," emerged from the interview data, and this construct included three domains: Getting Good Sleep, Getting Thrown Off, and Rolling With It. DISCUSSION: Findings support future strengths-based and multilevel sleep health-promoting interventions.

Intervention Effects on Morning and Stimulated Cortisol Responses Among Toddlers in Foster Care.

Toddlers in child welfare often have a dysregulated stress response. We tested whether toddlers with caregivers randomized to a 10-week attachment-based intervention, Promoting First Relationships (PFR; Kelly, Sandoval, Zuckerman, & Buehlman, 2008) would show post-intervention change in stimulated salivary cortisol patterns during a research home visit involving a separation-reunion procedure, compared to a condition including child development and resource advice, but no attachment strategies. At baseline and post intervention, toddlers with a caregiver change within 7 weeks of enrollment (n=48, age 10-25 months) provided 4 saliva samples during a 1.5-hour research visit, and samples the next morning. The categorical dependent variable was the pattern of cortisol activity during the course of the post-intervention research visit: Flat, Decreasing, Increasing. Multinomial logistic regression was used to test for post-intervention group differences in cortisol patterns, controlling for time of day, child's age, morning cortisol level, and baseline cortisol pattern. At baseline and post-intervention 92% of children demonstrated atypically low morning cortisol (< .21 ig/dL); Post-intervention, Flat, Decreasing and Increasing patterns were exhibited by 70%, 15%, and 15% of the sample, respectively. Significantly more children in the PFR condition showed an Increasing pattern. This may signal an intervention effect on separation-based stress response physiology.

Randomized Trial of Promoting First Relationships: Effects on Maltreated Toddlers' Separation Distress and Sleep Regulation after Reunification.

This study investigates the impact of an attachment focused intervention, Promoting First Relationships (PFR), on sleep problems among toddlers in child welfare recently reunified with their birth parent. Recently reunified parent-toddler dyads (n = 43) were drawn from a larger random control trial. Toddlers (11-36 months) and their parents were assessed in two-hour research home visits at enrollment (baseline), and a 6-month post-intervention follow-up. Measures included parental report of sleep problems and research visitor observation of separation distress (using the Toddler Attachment Sort-45). The PFR intervention predicted fewer sleep problems, adjusting for a baseline measure of sleep problems and other covariates. A path model showed evidence of an indirect effect of PFR on sleep problems through declines in separation distress. An attachment focused intervention like PFR that reduces infant separation distress can lead to reductions in sleep problems.

Impact of childhood trauma on the outcomes of a perinatal depression trial.

BACKGROUND: Childhood abuse and neglect have been linked with increased risks of adverse mental health outcomes in adulthood and may moderate or predict response to depression treatment. In a small randomized controlled trial treating depression in a diverse sample of nontreatment-seeking, pregnant, low-income women, we hypothesized that childhood trauma exposure would moderate changes in symptoms and functioning over time for women assigned to usual care (UC), but not to brief interpersonal psychotherapy (IPT-B) followed by maintenance IPT. Second, we predicted that trauma exposure would be negatively associated with treatment response over time and at the two follow-up time points for women within UC, but not for those within IPT-B who were expected to show remission in depression severity and other outcomes, regardless of trauma exposure. METHODS: Fifty-three pregnant low-income women were randomly assigned to IPT-B (n = 25) or UC (n = 28). Inclusion criteria included ≥ 18 years, >12 on the Edinburgh Postnatal Depression Scale, 10-32 weeks gestation, English speaking, and access to a phone. Participants were evaluated for childhood trauma, depressive symptoms/diagnoses, anxiety symptoms, social functioning, and interpersonal problems. RESULTS: Regression and mixed effects repeated measures analyses revealed that trauma exposure did not moderate changes in symptoms and functioning over time for women in UC versus IPT-B. Analyses of covariance showed that within the IPT-B group, women with more versus less trauma exposure had greater depression severity and poorer outcomes at 3-month postbaseline. At 6-month postpartum, they had outcomes indicating remission in depression and functioning, but also had more residual depressive symptoms than those with less trauma exposure. CONCLUSIONS: Childhood trauma did not predict poorer outcomes in the IPT-B group at 6-month postpartum, as it did at 3-month postbaseline, suggesting that IPT including maintenance sessions is a reasonable approach to treating depression in this population. Since women with more trauma exposure had more residual depressive symptoms at 6-month postpartum, they might require longer maintenance treatment to prevent depressive relapse.

Using machine learning to understand age and gender classification based on infant temperament.

Age and gender differences are prominent in the temperament literature, with the former particularly salient in infancy and the latter noted as early as the first year of life. This study represents a meta-analysis utilizing Infant Behavior Questionnaire-Revised (IBQ-R) data collected across multiple laboratories (N = 4438) to overcome limitations of smaller samples in elucidating links among temperament, age, and gender in early childhood. Algorithmic modeling techniques were leveraged to discern the extent to which the 14 IBQ-R subscale scores accurately classified participating children as boys (n = 2,298) and girls (n = 2,093), and into three age groups: youngest (< 24 weeks; n = 1,102), mid-range (24 to 48 weeks; n = 2,557), and oldest (> 48 weeks; n = 779). Additionally, simultaneous classification into age and gender categories was performed, providing an opportunity to consider the extent to which gender differences in temperament are informed by infant age. Results indicated that overall age group classification was more accurate than child gender models, suggesting that age-related changes are more salient than gender differences in early childhood with respect to temperament attributes. However, gender-based classification was superior in the oldest age group, suggesting temperament differences between boys and girls are accentuated with development. Fear emerged as the subscale contributing to accurate classifications most notably overall. This study leads infancy research and meta-analytic investigations more broadly in a new direction as a methodological demonstration, and also provides most optimal comparative data for the IBQ-R based on the largest and most representative dataset to date.
