The purpose of this study was to determine whether the effects of executive functions on school readiness outcomes were mediated by approaches to learning in Head Start preschoolers. Executive functions are cognitive skills, including inhibition, cognitive flexibility, and working memory, that are involved in learning as well as regulating behavior (Blair, Granger, & Razza, 2005; Espy, McDiarmid, Cwik, Stalets, Hamby, & Senn, 2004). Approaches to learning include important learning-to-learn skills such as persistence, initiative, and motivation (Fantuzzo, Perry, & McDermott, 2004). Based on previous literature, it was hypothesized that strong executive functions would support the development of positive approaches to learning, which in turn would lead to increased school readiness. To test this, data were collected on 179 four-year-old Head Start preschoolers. Children were assessed on executive functions (cognitive inhibition, cognitive flexibility, and working memory), approaches to learning (using both a teacher rating scale and a direct observation), school readiness, and verbal ability. Results indicated that approaches to learning partially mediated the relationship between executive functions and school readiness, providing support for the study's main hypothesis. Results are discussed in the context of preparing at-risk preschool children for success in school.

Prenatal cocaine exposure places infants at risk for developmental delays, particularly language delays (Chapman, 2000; Lester, LaGasse, & Seifer, 1998), which increase the likelihood that they will require special education services as children and show poor developmental outcomes (Delgado, Vagi, & Scott, 2006). This study used second-order latent growth curve modeling to identify the trajectory of language development of infants from 12 to 36 months of age who had completed a three-year early intervention program. This study also investigated the predictive ability of six factors related to the child, family, and intervention. Child factors included sex, birthweight, and cognitive ability at 12 months, a family factor included mother's education level, and intervention factors included intervention type and age at enrollment. Results revealed that language growth across the two-year period was quadratic, with growth declining initially, then accelerating after 24 months, compared to the nationally normed sample upon which standardized language scores were based. Being a girl, being enrolled in the program soon after birth, and having higher cognitive ability at 12 months predicted higher initial language ability. Intervention group predicted growth in language, such that both intervention groups predicted less or no initial decline compared to the primary care non-intervention group, and the center-based intervention group showed faster acceleration after 24 months compared to the home-based intervention group. Implications of these results on the research literature and practical applications were discussed.

The current study examined the impact of an early summer literacy program and the mediating effects of the home literacy environment on the language and literacy outcomes of a group of children at-risk for long-term developmental and academic delays. Participating children (n=54) were exposed to an intensive book-reading intervention each summer (June through mid August) over a 3-year period. The current study implemented an ex post facto, quasi-experimental design. This nonequivalent group design involved a pretest and posttest over three time points for a non-randomized treatment group and a matched non-treatment comparison group. Results indicated that literacy scores did improve for the children over the 3-year period; however, language scores did not experience the same rate of change over time. Receptive language was significantly impacted by attendance, and race/ethnicity. Expressive language was impacted significantly by gestational age and attendance. Results also indicated that language outcomes for young children who are exposed to a literacy program were higher than those who did not participate; however, only receptive language yielded significance at the p This study concluded that at-risk young children do benefit from center-based literacy intervention. This literacy experience, however, is also driven by the children’s home environment, their attendance to the program, whether they were premature or not and the type of caregiver.

This study examines factors that influence the language use of preschool children in a child/parent education program. The Preschool for Child/Parent Education Project was initiated to address concerns for at risk children and their families in the community of Nipawin, Saskatchewan. The families invited to participate in the program were identified as having preschool children who were potentially at risk for school success.<p> The language experiences of four preschool children were observed as they participated in one nine-week child/parent education session. The parents, caregivers and preschool teacher were interviewed regarding their views about the language experiences of the children.<p> The factors that emerged as having an influence on the children's use of language in the preschool program were: play center activities, direct instruction, authentic experiences, parent/caregiver involvement and teacher efficacy. Results showed that the children in the Preschool for Child/Parent Education Project experienced a program that understood the language needs of young children and the powerful influence of a supportive family.<p> Implications are drawn concerning the benefits of providing opportunities for language development and use during the crucial preschool years in a child/parent education program. Recommendations for further research suggest recognition of the effects of early language intervention on young children with difficult life circumstances.

Children's mental health problems are a significant public health concern. They are costly to society in both human and financial terms. This thesis contributes to the 'science of prevention' by examining issues related to the identification of children at risk of mental health problems. In particular, it was of interest to determine whether 'at-risk' children could be identified before the development of significant behavioural or emotional problems. Three areas were explored: family risk factors that predict the development of children's mental health problems, teachers' ability to identify family risk factors, and parent- and teacher-report screening methods. Data were collected from the parents and teachers of over 1000 children in preschool to Year 3 as part of the Promoting Adjustment in Schools (PROMAS) Project. Parents and teachers each completed two questionnaires at two time points, one year apart. Parents completed the Family Risk Factor Checklist - Parent (FRFCP) and the Child Behaviour Checklist (CBCL) and the equivalent instruments for teachers were, respectively, the Family Risk Factor Checklist - Teacher (FRFC-T) and the Teacher Report Form (TRF). The FRFC-P and FRFC-T were original to the current research and were designed to assess children's exposure to multiple family risk factors across five domains: adverse life events and instability (ALI), family structure and socioeconomic status (SES), parenting practices (PAR), parental verbal conflict and mood problems (VCM), and parental antisocial and psychotic behaviour (APB). Paper 1 investigated the psychometric properties of the FRFC-P and the potential for its use at a population-level to establish community risk factor profiles that subsequently inform intervention planning. The FRFC-P had satisfactory test-retest reliability and construct validity, but modest internal consistency. Risk assessed by the PAR domain was the most important determinant of mental health problem onset, while the PAR, VCM, and APB domains were the strongest predictors of mental health problem persistence. This risk factor profile suggests that, for the studied population, the largest preventive effects may be achieved through addressing parenting practices. Paper 2 examined teachers' knowledge of children's exposure to family risk factors using the FRFC-T. While teachers had accurate knowledge of children's exposure to risk factors within the ALI and SES domains, they had poor knowledge of children's exposure to risk factors within the PAR, VCM, or APB domains - the types of risk factors found in Paper 1 to be the most strongly related to children's mental health problems. Nevertheless, teachers' knowledge of children's exposure to risk factors within the ALI and SES domains predicted children's mental health problems at one year follow-up even after accounting for children's behaviour at the first assessment. Paper 3 investigated the potential of both the FRFC-P and FRFC-T for identifying individual, at-risk children. The accuracy of the FRFC in predicting internalising versus externalising disorders was compared against behavioural and simple nomination screening methods. For both parents and teachers, the behavioural screening methods were superior, however, the simple nomination method also showed promise for teachers. Both parents and teachers were more accurate at identifying children at risk of externalising mental health problems than children at risk of internalising problems. The performance of the FRFC and simple nomination methods in identifying children for selective interventions, before the development of significant behavioural or emotional problems, was also tested. Both the FRFC and simple nomination methods showed only modest predictive accuracy for these children. Combined, the results suggest that while on the one hand, the FRFC is useful for population level screening to inform intervention planning, on the other hand, it falls short of achieving good predictive accuracy for individual children. Future research should investigate ways to optimise predictive accuracy for individual children, particularly those at risk of developing internalising disorders. One option may be to use the FRFC in conjunction with behavioural screening methods. The challenge is to develop accurate screening methods that remain practical to complete at a population level. Finally, this body of research provides insight into the feasibility of offering selective preventive interventions within the school setting. While significant obstacles remain, there were several promising indications that using screening methods such as FRFC-T or simple nomination, teachers may be able to identify children earlier on the developmental pathway, before significant behavioural or emotional symptoms have developed.

Among preschool-aged children, conduct problems (CP) are the number one reason for referral to mental health professionals. Research has consistently indicated that behavioral parent training (BPT) is the most effective technique for treating children’s disruptive behavior; however, there is a lack of research regarding BPT effects in children below the age of 3. Preventive behavioral parent training (PBPT) can be considered a preventive extension of BPT. The purpose of this study was to determine the degree to which PBPT might yield immediate effects in reducing rates of conduct problems (i.e., noncompliance and tantrums) displayed by typically developing young children. Overall, findings indicated that all four child participants displayed decreased rates of noncompliance and tantrums as predicted.

The purpose of this research study was to examine the effectiveness of training for college work study students who participated in an America Reads program, which was designed to help at-risk children struggling with reading. Two groups participated in this research study. One group of college tutors had minimal training in reading strategies at the beginning of the study and the other group of college tutors had continuous training and feedback throughout the study. The research study sought to answer the following questions: 1) Will training for college student tutors in the area of reading, more specifically in the strategies and skills, help improve their comprehension and vocabulary? And 2) Will training for college student tutors in the area of reading, more specifically in strategies and skills, significantly improve the comprehension and vocabulary scores of the children being tutored? This was a quasi-experimental research design, used to examine the effectiveness of training college students participating in the America Reads program. The tutors were pre-and post-tested, measuring both their vocabulary and comprehension knowledge at the beginning and the end of the study. The children being tutored were also pre- and post-tested, measuring both their vocabulary and comprehension knowledge at the beginning and the end of the study. The statistical analysis for this design was the analysis of covariance (ANCOVA). The ANCOVA was used to handle the main threat to the internal validity of this research design, due to the fact that the tutors for the control and experimental group were not selected randomly. The tutors and the children were randomly assigned to two groups. The control group of tutors received minimal training (11 hours) and the experimental group received the same minimal training with extra (21 hours) weekly training added. The study began in October 1999 and ended in December 1999. The tutoring sessions were 1 ½ hours long, three days a week. The training for the experimental group was for 1 ½ to 2 hours weekly. The results from this study found no significant difference between the control and experimental groups on comprehension, as measured by the assessment instruments. The results from this study did find, however, a significant difference between the control and the experimental groups on vocabulary, as measured by the assessment instruments.

Previous research has demonstrated the effectiveness of programs that include a videotaped self-observation component. The self-observation protocols, however, have not been clearly specified within programs that teach and report parents’ use of general teaching strategies. The current study investigates the effects of a training package with a self-observation component to teach parents to improve teaching interactions with their children at-risk for a developmental delay using an AB design replicated across participants. Data were collected across play interactions to assess the number of parent teaching episodes, child target responses, and various parent and child relationship qualities. Relationship quality measures included parent and child affect and engagement, parent directives, parent confidence and stress, and parent and child interest. The results of this study suggest that the training package was effective in that parents engaged in higher rates of teaching, their children engaged in more desired responding, and certain aspects of the parent-child interaction were enhanced. These results are discussed in terms of the effects on the parent-child teaching interaction and implications for future use of parent self-observation techniques.
