RESUMO

Oppositional defiant disorder (ODD) is a commonly diagnosed childhood behavior disorder, yet knowledge of relations between ODD and early neuropsychological functions, particularly independent of attention deficit/hyperactivity disorder (ADHD), is still limited. In addition, studies have not examined neuropsy chological functioning as it relates to the different ODD symptom dimensions. Structural equation modeling was used to investigate how preschool neuropsychological functioning predicted negative affect, oppositional behavior, and antagonistic behavior symptom dimensions of ODD in 224 six-year-old children, oversampled for early behavior problems. Working memory, inhibition, and sustained attention predicted negative affect symptoms of ODD, controlling for ADHD, whereas delay aversion uniquely predicted oppositional behavior, controlling for ADHD. Delay aversion also marginally predicted antagonistic behavior, controlling for ADHD. Results demonstrate that different ODD symptom dimensions may be differentially predicted by different neuropsychological functions. The findings further underscore the importance of future research on ODD to take into account the possible heterogeneity of both symptoms and underlying neuropsychological functioning.

RESUMO

Considerable research has examined the effects of maternal depression on children, but few studies have focused on the relation between paternal and child depressive symptoms, particularly during early childhood. Even fewer studies have been longitudinal, leaving open questions about how paternal and child depression covary over time. The present study sought to address this gap by examining the relation between fathers' and children's depressive symptoms over a 3-year period. Participants were 153 preschool children with behavior problems and their parents. Three longitudinal analytic approaches were used to examine how father and child depression change together and predict one another over time. Additional analyses examined whether externalizing problems or maternal depression might account for the associations between fathers' and children's depressive symptoms. Changes in paternal depression significantly predicted changes in father-reported and mother-reported child depressive symptoms. These effects were evident both in year-to-year fluctuations and in linear trajectories across the 3-year period. Cross-lagged analyses suggested that these relations may have been driven by father-effects; paternal depression at one time point predicted child depression at the next time point, but child depression did not significantly predict later paternal depression. We found little evidence that externalizing problems or maternal depression accounted for the relations between fathers' and children's depressive symptoms. Results provide convergent evidence that fathers' depression may play an important role in the development of depressive symptoms in young children and underscore the importance of including fathers in studies of depression in families.

RESUMO

Reciprocal relations between children's conduct disorder (CD) symptoms and parenting behaviors were examined across the preschool years. Participants were 199 children (M = 44.26 months, SD = 3.37; 92 girls) and their 199 mothers and 158 fathers. CD symptoms were assessed via structured interviews; parenting was assessed via observational and self-report measures. Fixed effects models were used to assess within-individual changes and traditional cross-lagged models were used to assess between-individual changes; comparisons by sex were also carried out. Increases in maternal overreactivity predicted increases in CD symptoms. During the later preschool years, decreases in maternal warmth predicted increases in CD symptoms and increases in CD symptoms predicted increases in paternal overreactivity. Reciprocal effects were found between girls' CD symptoms and paternal negative affect. Findings suggest maternal and paternal influence on the development of CD symptoms and suggest that CD symptoms influence fathers' parenting during the preschool years.

RESUMO

Preschool teachers have important impacts on children's academic outcomes, and teachers' misperceptions of children's academic skills could have negative consequences, particularly for low-income preschoolers. This study utilized data gathered from 123 preschool teachers and their 760 preschoolers from 70 low-income, racially diverse centers. Hierarchical linear modeling was utilized to account for the nested data structure. Even after controlling for children's actual academic skill, older children, children with stronger social skills, and children with fewer inattentive symptoms were perceived to have stronger academic abilities. Contrary to hypotheses, preschoolers with more behavior problems were perceived by teachers to have significantly better pre-academic abilities than they actually had. Teachers' perceptions were not associated with child gender or child race/ethnicity. Although considerable variability was due to teacher-level characteristics, child characteristics explained 42% of the variability in teachers' perceptions about children's language and pre-literacy ability and 41% of the variability in teachers' perceptions about mathability. Notably, these perceptions appear to have important impacts over time. Controlling for child baseline academic skill and child characteristics, teacher perceptions early in the preschool year were significantly associated with child academic outcomes during the spring for both language and pre-literacy and math. Study implications with regard to the achievement gap are discussed.

RESUMO

Conduct disorder (CD) symptoms often emerge during the preschool years, but it is not clear whether they predict later symptoms. The present study examined whether age 3 CD symptoms predict age 6 CD symptoms beyond oppositional defiant disorder (ODD) and attention-deficit/hyperactivity disorder-hyperactive/impulsive (ADHD-HI) symptoms. Participants were 216 preschool children (M Age  = 44.19 months), including an externalizing sample (n = 161) and a comparison group (n = 55). Parents were administered a diagnostic interview when children were 3 years old and again 3 years later. The externalizing sample exhibited more CD symptoms than the comparison sample. In the externalizing sample, initial CD symptoms predicted later CD symptoms above and beyond ODD and ADHD HI symptoms; this relation was stronger for boys than for girls. Stealing, property destruction, and fighting independently predicted later CD symptoms. CD symptoms also predicted subsequent ADHD HI symptoms and predicted ODD symptoms at a level that approached significance. Results support the predictive validity of CD symptoms in preschool.

RESUMO

Galectins are innate immune system regulators associated with disease progression in cancer. This paper aims to investigate the correlation between mutated cancer-critical genes and galectin levels in breast cancer patients to determine whether galectins and genetic profiles can be used as biomarkers for disease and potential therapy targets. Prisma Health Cancer Institute's Biorepository provided seventy-one breast cancer samples, including all four stages spanning the major molecular subtypes and histologies. Hotspot mutation statuses of cancer-critical genes were determined using multiplex PCR in tumor samples from the same patients by Precision Genetics and the University of South Carolina Functional Genomics Core Facility. The galectin-1, -3, and -9 levels in patients' sera were analyzed using Enzyme-linked Immunosorbent Assay (ELISA). An analysis was performed using JMP software to compare mean and median serum galectin levels between samples with and without specific cancer-critical genes, including pooled t-test, Wilcoxon Rank Sum Test, ANOVA, and Steel Dwass Test (α=0.05). Our analysis indicates that KIT mutations correlate with elevated serum levels of galectin-9 in patients with breast cancer. In patients with Luminal A subtype, FLT3 mutation correlates with lower serum galectin-1 and -9 levels and TP53 mutations correlate with higher serum galectin-3 levels. Patients with invasive ductal carcinoma had significantly higher serum galectin-3 levels than patients with ductal carcinoma in situ. Patients with both TP53 and PIK3CA mutations exhibit elevated serum galectin-3 levels, while patients with one or neither mutation show no significant difference in serum galectin-3 levels. In addition, metastatic breast cancer samples were more likely to have a KIT or PIK3CA mutation compared to primary breast cancer samples. The relationship between genetic mutations and galectin levels has the potential to identify appropriate candidates for combined therapy, targeting genetic mutations and galectins. Further understanding of the effect of genetic mutations and galectin levels on cancer progression and metastasis could aid in the search for biomarkers for breast cancer diagnosis, disease progression, and prognosis.

RESUMO

The present study examined whether ineffective discipline, single parent status, social support, parent involvement, and parent depression predicted changes in preschoolers' (N = 129) behavior problems. This study also evaluated whether child sex and ethnicity moderated the relationships between these variables and changes in problem behavior. Parents completed questionnaires at the beginning of the study, and parent, teacher, and observational ratings of children's behavior problems were collected twice during the school year. Parents' own social support predicted improvement for boys and parent depression was associated with worsening symptoms for girls. Single parenthood and parent involvement predicted changes in behavior problems for the sample as a whole. Several significant ethnic differences emerged, highlighting the importance of considering cultural context in studies of parenting and child externalizing behavior.

RESUMO

This study examined the relationship between social functioning and emergent academic development in a sample of 467 preschool children (M = 55.9 months old, SD = 3.8). Teachers reported on children's aggression, attention problems, and prosocial skills. Preliteracy, language, and early mathematics skills were assessed with standardized tests. Better social functioning was associated with stronger academic development. Attention problems were related to poorer academic development controlling for aggression and social skills, pointing to the importance of attention in these relations. Children's social skills were related to academic development controlling for attention and aggression problems, consistent with models suggesting that children's social strengths and difficulties are independently related to their academic development. Support was not found for the hypothesis that these relationships would be stronger in boys than in girls. Some relationships were stronger in African American than Caucasian children. Children's self-reported feelings about school moderated several relationships, consistent with the idea that positive feelings about school may be a protective factor against co-occurring academic and social problems.

RESUMO

Low levels of enrollment and attendance in parent training programs present major problems for researchers and clinicians. The literature on enrollment and attendance in prevention programs is especially limited, and these constructs may be particularly difficult to address in this context. Further, most previous research has not made the distinction between enrollment and attendance. This study describes predictors of enrollment and attendance in a behavioral parent training program intended to prevent conduct problems in preschoolers. Information was gathered from 106 preschoolers, their parents, and their teachers. Parent socioeconomic status (SES), single parent status, ethnicity, child externalizing behavior, parent depressive symptoms, and parent social support were investigated as possible predictors of families' enrollment and attendance. Only 48% of the families that had already provided informed consent and completed demographic questionnaires actually enrolled in the parent training program; parents with lower incomes and lower levels of social support were less likely to enroll. In addition, African-American and Puerto Rican families were less likely to enroll than Caucasian families. The average attendance rate for enrolled parents was 61%; dual parents and parents with children evidencing externalizing behavior problems attended more parent training sessions. Parent depression was not associated with enrollment or attendance. Significant relationships were maintained when controlling for other predictors including SES and when accounting for center-level variance. In addition, three distinct patterns of attendance were observed, which may have practical implications related to retention strategies.

RESUMO

Preschools provide a promising setting in which to conduct preventive interventions for childhood problems, but classroom programs can only be effective if teachers are willing and able to implement them. This study is one of the first to investigate predictors of the frequency of teacher participation in a classroom-based, randomized controlled trial of an integrated prevention program for preschoolers. The intervention was designed to promote school readiness with an integrated social and academic program, to be implemented by teachers with the support of classroom consultants. The current study is part of a larger project conducted with Head Start and community child care centers that serve primarily economically disadvantaged families; 49 teachers from 30 centers participated in this study. Overall, teachers conducted approximately 70% of the program activities. Participation decreased significantly over time from the first to the final week of the intervention, and also decreased within each week of the intervention, from the first to the final weekly activity. Teachers working at community child care centers implemented more intervention activities than did Head Start teachers. Teacher concerns about the intervention, assessed prior to training, predicted less participation. In addition, teachers' participation was positively related to their perception that their centers and directors were supportive, collegial, efficient, and fair, as well as their job satisfaction and commitment. Teacher experience, education, ethnicity, and self-efficacy were not significantly related to participation. In multi-level models that considered center as a level of analysis, substantial variance was accounted for by centers, pointing to the importance of considering center-level predictors in future research.

RESUMO

Ethnic and racial differences between client and therapist affect therapy processes and outcomes, but little is known about the extent to which therapists have dialogues about their differences in therapy. A survey on this topic was completed by 689 APA-licensed psychologists with experience conducting cross-cultural therapy. Most psychologists reported having such discussions, but with less than half of their cross-ethnic/racial clients. Therapists and clients were equally likely to initiate discussions. Reasons for discussing differences varied greatly. Therapists consistently described themselves as comfortable with and skilled at these discussions, and reported that discussions facilitated therapy. Therapists who were female, older, nonminority, less experienced with diverse clients, and viewed training as an important factor were more likely to have discussions about differences. Results point to the need to better understand if, when, and how ethnic and racial differences should be addressed in therapy. (PsycINFO Database Record (c) 2011 APA, all rights reserved).

RESUMO

Data are presented from two samples of preschool children to evaluate the reliability, concurrent validity, and predictive validity of the ADHD, ODD, and CD sections of the Diagnostic Interview Schedule for Children, Fourth Edition (DISC-IV). Information was obtained from a community sample of 128 children (Mage = 53.16 months; 63 girls) and from a sample of 72 externalizing children (Mage = 45.23 months; 31 girls) plus 25 control children (Mage = 44.51 months; 8 girls). In both studies, the DISC-IV was administered to parents along with parent and teacher behavior rating scales, and teacher rating scales were obtained again later to evaluate the predictive validity of the DISC-IV (after approximately 6 months in Study 1, and 3 years in Study 2). The ADHD and ODD sections exhibited acceptable internal consistency in both studies, and showed concurrent validity with parent behavior rating scales. In both studies, the ADHD section was also concurrent with teacher reports. In Study 2, the ADHD, ODD, and CD sections distinguished externalizing children from controls. In both studies, the ADHD section predicted future teacher ratings beyond initial teacher ratings, and beyond initial parent rating scales; the ODD section similarly predicted later teacher ratings in Study 1. Findings provide strong support for the utility of the ADHD section for preschool children and moderate support for the ODD and CD sections.

RESUMO

The relationships between preschool children and their teachers are an important component of the quality of the preschool experience. This study used attribution theory as a framework to better understand these relationships, examining the connection between teachers' perceptions of children's behavior and teachers' behavior toward those children. One hundred seven preschool children and 24 preschool teachers participated in this study. Two teachers reported on each child's behavior using the Teacher Report Form of the Child Behavior Checklist. Commands and praise directed toward children by the teachers in the study were coded from classroom videotapes. Teachers gave more commands to children they perceived as having greater general behavior problems, even after controlling for the shared variance in the other classroom teacher's report of the child's behavior. Implications for school psychologists, teachers, and researchers are discussed.

RESUMO

This study examined the role of ethnicity in untrained observers' ratings of videotaped mother-child interactions. Participants were Black, White, and Latino undergraduates (N = 109), who rated videotapes of 4 Black, 4 White, and 4 Latino mother-child dyads. Overall, participants of different ethnicities showed more similarities than differences in their ratings of parent-child behavior. There was, however, evidence that participant ethnicity and parent-child ethnicity interacted for ratings of child defiance/negative emotion. Black and White participants differed in their ratings of Black and White children's defiance/negative emotion, with members of each ethnic group favoring children of their own ethnic group. Intergroup contact appeared to play a role in ratings of parent behavior among Black observers. Black observers who reported low intergroup contact tended to rate Black mothers high on strictness and low on permissiveness. More research is needed to better understand the role of ethnicity in observers' ratings of parent and child behavior.

RESUMO

This study investigated multiple forms of home and school assessment as predictors of parent-rated behavior problems across a preschool year. Participants were a community sample of 79 preschool children, their parents, and their teachers. Parent ratings of behavior problems were obtained toward the beginning of the school year and approximately 6 months later. Behavior problems were also assessed early in the school year using parent structured interviews, teacher-rating scales, and classroom observations of problem and prosocial behavior. Consistent with hypotheses, each assessment method significantly predicted year-end parent ratings of behavior problems, even above initial ratings.

RESUMO

This chapter reviews selected research on the education of low-socioeconomic status (SES) children from birth through the first years of elementary school. Themes include the importance of early academic skills and interest to later achievement; the benefits of integrating knowledge from research on mental health and other areas; the need to utilize and build children's strengths as well as address their weaknesses; and a call to connect research to practice and policy. Relevant research on race and culture is reviewed because ethnic minority low-SES children are at great risk of poverty. Gender is discussed because low-SES boys have poorer general achievement than girls, while very few low-SES girls pursue careers in math- and science-related fields.
