Posttraumatic Stress Symptoms in Adolescent Survivors of Childhood Cancer and Their Mothers

We examined symptoms of posttraumatic stress disorder (PTSD) in adolescent survivors of childhood cancer and their mothers and the contribution of family functioning, including perceived emotional support and familial conflict, and individual factors including life stress and severity of disease to PTSD symptoms. Participants were 52 adolescent cancer survivors and their mothers and 42 healthy adolescent counterparts and their mothers. Findings revealed that mothers of cancer survivors endorsed more PTSD symptoms than did their healthy counterparts and that survivors and mothers also reported greater recent and past stressful life events. Although no survivors met clinical criteria for a PTSD diagnosis, over 36% endorsed mild subthreshold symptomatology. Findings are discussed in the context of understanding PTSD symptoms within a family systems framework.

A Comparison of School Readiness Outcomes for Children Randomly Assigned to a Head Start Program and the Program's Wait List

A research study with a wide range of outcomes related to school readiness, including health, social skills, cognitive skills, and language skills was conducted with eligible 4-year-old applicants and their parents within a southeastern Head Start program of high quality. Children and their families in the Head Start treatment and wait list comparison groups were given a battery of assessments. The study used growth curve modeling and traditional analysis of variance when only 2 measurements of outcomes were available. Initial status was equivalent and the growth rates for the Head Start children were statistically significantly faster than the comparison children on the receptive vocabulary and phonemic awareness measures. There was a statistically significant time by group interaction and main effect of time for the problem behavior index of the social functioning measure. The parent report of health outcomes also showed statistically significant differences between the 2 groups with the treatment group reporting more healthy responses.

Structural model of head start classroom quality

Abstract The purpose of this research study was to develop, test, and validate a model that identifies the characteristics and beliefs of teachers and aides, and the classroom structural dimensions associated with Head Start classroom quality. The quality of classroom teaching practices was collected using the Assessment Profile for Early Childhood Programs: Research Version. Classroom structural characteristics were collected by observers. Teachers and teacher aides completed three self-report instruments: Teacher Beliefs Scale, Instructional Activities Scale, and Family Involvement Survey. Data analyses were conducted using structural equation modeling with the Lisrel VII computer program. The model was tested with Year 1 classroom level data and validated with Year 2 data. Education Level was shown to directly affect Inappropriate Beliefs, which impacted Inappropriate Instructional Activities, which influenced Classroom Quality. Neither Education Level nor Teacher Beliefs had direct effects on Classroom Quality, but they had indirect effects through Instructional Activities. Classroom Structure was associated directly with Quality. Education Level and Classroom Quality were associated directly with Attitudes Toward Families.

Immigration and attendant psychological sequelae: A comparison of three waves of Iraqi immigrants.

Acculturation, the process by which individuals or groups transition from one or more cultures into another, can be complex and often stressful. In many cases, reason for immigration can contribute, both positively and negatively, to levels of acculturative stress. Immigrants to the United States from Iraq over the past several decades have shifted in terms of prevalence, reason for and ease of immigration, and pre and postmigration trauma among individuals and groups. The authors examined the psychological by-products of acculturative stress by measuring posttraumatic stress disorder, anxiety, and depression among three distinct waves of immigrants from Iraq. The authors found support for the hypotheses that these variables were positively correlated with recency of immigration. Implications for psychological practitioners are discussed.

Effects of School Racial Composition on K–12 Mathematics Outcomes A Metaregression Analysis

Recently published social science research suggests that students attending schools with concentrations of disadvantaged racial minority populations achieve less academic progress than their otherwise comparable counterparts in more racially balanced or integrated schools, but to date no meta-analysis has estimated the effect size of school racial composition on mathematics outcomes. This metaregression analysis reviewed the social science literature published in the past 20 years on the relationship between mathematics outcomes and the racial composition of the K–12 schools students attend. The authors employed a two-level hierarchical linear model to analyze the 25 primary studies with 98 regression effects. Results indicate that school racial isolation has a small statistically significant negative effect on overall building-level mathematics outcomes. This relationship is moderated by the size of the sample in the study and by the way the independent variable was operationalized. Although it is small, the effect size is substantively meaningful. The effects are stronger in secondary compared to elementary grades, and racial gaps widen as students age. The emergence and widening of the race gaps as students move through the grades suggest that the association of racial segregation with mathematics performance compounds over time. Implications for educational policy and future research are discussed.

Preventive Resources and Emotion Regulation Expectancies as Mediators Between Attachment and College Students' Stress Outcomes

In this study the authors examined both preventive psychological coping resources and negative mood regulation expectancies as potential mediators between parental attachment and two types of stress outcomes: stress symptoms and stress-produced emotions. Data were collected from 390 college students and separate structural equation models were tested for the outcomes of stress symptoms and emotions. Results suggested that for both models, as hypothesized, preventive resources and negative mood regulation expectancies functioned as mediators. Further, there was evidence that these results were similar for the model in which stress symptoms were used as an outcome, as well as the model in which stress-produced emotions were used as the outcome. Implications for a more complete understanding of psychological resources promoted by secure attachment are discussed. Copyright 2006 by the American Psychological Association.

Examining Elementary Social Studies Marginalization: A Multilevel Model

Utilizing data from the National Center for Education Statistics Schools and Staffing Survey (SASS), a multilevel model (Hierarchical Linear Model) was developed to examine the association of teacher/classroom and state level indicators on reported elementary social studies instructional time. Findings indicated that state testing policy was a significant predictor of elementary teachers’ reported time spent on social studies instruction. Teachers’ perceptions of workplace autonomy and grade level were also associated with increased time on social studies. Conversely, teacher credentials, classroom socioeconomic contexts, and test design were not substantially associated with social studies instructional time. This study suggests that state policy mandates, grade-specific curricular organization, and teacher disposition have a substantial impact on the prioritization of social studies in US elementary schools.

Is More Really Better? Examining Perceived Benefits of an Extended Student Teaching Experience

The authors surveyed student teachers in a yearlong internship and their peers in a traditional semester-long internship to compare perceptions across different practice teaching experiences. All participants were enrolled in the same university and were similar across gender, age, ethnicity, and undergraduate educational experiences. The students in the yearlong internship reported a better relationship with their supervising teacher, greater knowledge of school policies and procedures, and higher scores for the perceived adequacy of time spent in school than did the students in the semester internship. The two groups did not differ in perceptions of their teaching ability, which were generally favorable. The authors discuss the outcomes regarding continuing challenges professional development programs face when building and sustaining effective clinical experiences.

Classroom Quality, Concentration of Children with Special Needs, and Child Outcomes in Head Start:

The associations among classroom quality, classroom percentage of children with special needs, and child outcome measures were tested in low- and high-quality classrooms using hierarchical linear modeling (HLM). No main effect on child outcomes for the classroom concentration of children with special needs was observed. However, an interaction between classroom quality and the percentage of children in the classroom who had special needs was found. A high-quality classroom environment serving no children with special needs was associated with more favorable classroom mean scores on social behaviors for typically developing children. Inversely, the combination of high-quality classroom environment and more than 20% children with special needs was associated with more problem behaviors and lower scores in print concepts for typical children.

Situational analysis of parenting problems for caregivers of children with sickle cell syndromes.

A situational analysis of problematic situations was conducted for 37 caregivers of children with sickle cell disease (SCD) who ranged in age from 5 to 13 years. Participants responded to a semistructured interview related to caring for a child with SCD. The interview included the domains of medication adherence, nutrition, minimizing and coping with pain episodes, social problems, academic difficulties, and childrens expression of negative feelings related to having SCD. Caregivers described a total of 356 problems. Almost all caregivers reported experiencing problems with their childrens nutrition (n = 35), minimizing pain episodes (n = 34), and their children expressing feelings about having SCD (n = 33). Moderately challenging and emotionally upsetting problems were reported for coping with pain episodes. The total number of problems was significantly higher for boys than for girls. Nutrition issues were more frequently reported for younger children. Findings have salient clinical implications for the care of children with SCD.
