Examining the relationships between early childhood experiences and adolescent and young adult health status in a resource-limited population: A cohort study

BACKGROUND

Adolescence is a critical point in the realization of human capital, as health and educational decisions with long-term impacts are made. We examined the role of early childhood experiences on health, cognitive abilities, and educational outcomes of adolescents followed up from a longitudinal cohort study in Pakistan, hypothesizing that early childhood experiences reflecting poverty would manifest in reduced health and development in adolescence.

METHODS AND FINDINGS

Adolescents/young adults previously followed as children aged under 5 years were interviewed. Childhood data were available on diarrhea, pneumonia, and parental/household characteristics. New data were collected on health, anthropometry, education, employment, and languages spoken; nonverbal reasoning was assessed. A multivariable Bayesian network was constructed to explore structural relationships between variables. Of 1,868 children originally enrolled, 1,463 (78.3%) were interviewed as adolescents (range 16.0-29.3 years, mean age 22.6 years); 945 (65%) lived in Oshikhandass. While 1,031 (70.5%) of their mothers and 440 (30.1%) of their fathers had received no formal education, adolescents reported a mean of 11.1 years of education. Childhood diarrhea (calculated as episodes/child-year) had no association with nonverbal reasoning score (an arc was supported in just 4.6% of bootstrap samples), health measures (with BMI, 1% of bootstrap samples; systolic and diastolic blood pressure, 0.1% and 1.6% of bootstrap samples, respectively), education (0.7% of bootstrap samples), or employment (0% of bootstrap samples). Relationships were found between nonverbal reasoning and adolescent height (arc supported in 63% of bootstrap samples), age (84%), educational attainment (100%), and speaking English (100%); speaking English was linked to the childhood home environment, mediated through maternal education and primary language. Speaking English (n = 390, 26.7% of adolescents) was associated with education (100% of bootstrap samples), self-reported child health (82%), current location (85%) and variables describing childhood socioeconomic status. The main limitations of this study were the lack of parental data to characterize the home setting (including parental mental and physical health, and female empowerment) and reliance on self-reporting of health status.

CONCLUSIONS

In this population, investments in education, especially for females, are associated with an increase in human capital. Against the backdrop of substantial societal change, with the exception of a small and indirect association between childhood malnutrition and cognitive scores, educational opportunities and cultural language groups have stronger associations with aspects of human capital than childhood morbidity.

Assessing Early Childhood Fluid Reasoning in Low- and Middle-Income Nations: Validity of the Wechsler Preschool and Primary Scale of Intelligence Across Seven MAL-ED Sites

An adapted version of the Wechsler Preschool and Primary Scale of Intelligence—Third Edition (WPPSI-III) was administered to assess cognitive functioning among 1,253 5-year-old children from the Malnutrition and Enteric Disease (MAL-ED) study—an international, multisite study investigating multiple aspects of child development. In this study, the factor structure and invariance of the WPPSI-III were examined across seven international research sites located in Bangladesh, Brazil, India, Nepal, Pakistan, South Africa, and Tanzania. Using a multiple indicator multiple cause (MIMIC) modeling approach, the findings supported the validity of a fluid reasoning dimension (comprised of block design, matrix reasoning, and picture completion subscales) across each of the seven sites, although the scores were noninvariant. Accordingly, these scores are recommended for research purposes and understanding relationships between variables but not for mean comparisons or clinical purposes.

Measuring home environments across cultures: Invariance of the HOME scale across eight international sites from the MAL-ED study

The home environment provides the context for much of a child's early development. Examples of important aspects of the home environment include safety, cleanliness, and opportunities for cognitive stimulation. This study sought to examine the psychometric properties of an adapted form of the Home Observation for the Measurement of the Environment (HOME; Caldwell & Bradley, 1984, 2003) across the eight international sites of the MAL-ED project (Dhaka, Bangladesh; Vellore, India; Bhakatapur, Nepal; Naushahro Feroze, Pakistan; Fortaleza, Brazil; Loreto, Peru; Venda, South Africa; Haydom, Tanzania), to identify a factor structure that fit the data at all sites, and to derive a subset of items that could be used to examine home environmental characteristics across sites. A three-factor structure (i.e., Emotional and Verbal Responsivity; Clean and Safe Environment; Child Cleanliness) was identified, and partial measurement equivalence/invariance across sites was supported. Overall, these findings lend support for the use of portions of this abbreviated and adapted version of the HOME for use among heterogeneous, cross-cultural groups in low- and middle-income nations.

Subcutaneous diphtheria and tetanus vaccines in children with haemophilia: A pilot study and review of the literature

INTRODUCTION

Subcutaneous (SQ) vaccination has emerged as standard of care in children with severe bleeding disorders to reduce unnecessary factor exposure and avoid provoking an intramuscular bleed, but little is known about comparative immunogenicity to intramuscular (IM) vaccination.

AIM

To confirm immunogenicity of Diphtheria Tetanus acellular Pertussis (DTaP) vaccines administered SQ to individuals <6 years old with haemophilia.

METHODS

We performed a retrospective and prospective pilot study of tetanus and diphtheria antibody titres among patients evaluated at our Haemophilia Treatment Centre between 2015-2016. Children with haemophilia who had received three to four doses of DTaP containing vaccine administered SQ were eligible.

RESULTS

Eight children met inclusion criteria. The mean age at the time of diphtheria and tetanus antibody testing was 21.1±17.8 months. All children who received SQ diphtheria and tetanus developed a positive antibody titre to both antigens. There was no statistically significant difference in distribution of titre values. The average time between the last dose of vaccine and antibody testing was 6.6±3.9 months among SQ vaccinated subjects. Minor injection site reactions were common with SQ vaccines.

CONCLUSION

SQ administration of diphtheria and tetanus vaccination appears to be immunogenic in a pilot study of Haemophilia patients and supports this practice as the standard of care for this population.

Metabolic control and academic achievement over time among adolescents with type 1 diabetes

The relation between metabolic control (HbA1c) and achievement (grade point average [GPA]) was examined over a period of 2.5 years (every 6 months) employing a dynamical systems approach that allowed for the examination of whether HbA1c was associated with change in subsequent GPA and vice versa. Metabolic control tends to deteriorate (i.e., with higher HbA1c reflecting poorer metabolic control) during adolescence. It was hypothesized that these higher levels of HbA1c would limit subsequent increases in GPA. The sample included 252 adolescents (Mbaseline age = 12.49 years, SD = 1.53; 53.6% female) with Type 1 diabetes. Mothers' report and school records provided information on relevant demographics and GPA; medical records provided values of HbA1c. Two simultaneous coupled change equations (i.e., examining current values in 1 variable associated with changes in the other) controlling relevant risk indicators (i.e., age, sex, disease duration, insulin delivery method, IQ) revealed higher levels of HbA1c limited increases in GPA. Higher levels of GPA, however, were not associated with change in HbA1c except for 2 instances where moderation existed by disease duration and IQ. Higher GPA was associated with slower increases in HbA1c over time for youth with shorter disease duration and lower IQ. These results affirm the importance of maintaining good metabolic control to facilitate adequate school performance across the adolescent years. Further, the results suggest that factors related to school achievement may protect adolescents who are newly diagnosed or who have low cognitive ability from subsequent deterioration in metabolic control.

Cross-Context Agreement of the Adjustment Scales for Children and Adolescents

Interobserver agreement of children's problem behavior was assessed using two samples of special education students ages 5 to 18 years. The first sample had observers from the same setting (N= 71); the second sample (N= 182) had observers from different settings with no concurrent observation. Regular and special education teachers and aides completed the Adjustment Scales for Children and Adolescents (ASCA; McDermott, Marston, & Stott, 1993). Inter- and intraclass correlations were generally significant for both samples, with some exceptions. Substantial interobserver agreement was found for the same-setting sample; however, agreement coefficients were lower for the different-setting sample and some level effects were noted. Overall, interobserver agreement for the ASCA was supported in common settings, but rating variability was evident across classrooms and appears indicative of contextual influences on behavior.

Preschool Children's Learning Behaviors, Concept Attainment, Social Skills, and Problem Behaviors: Validity Evidence for Preschool Learning Behaviors Scale Scores

This study provides concurrent and predictive validity and test-retest reliability evidence for scores from the preschool teacher-completed Preschool Learning Behaviors Scale (PLBS; McDermott, Green, Francis, & Stott, 2002) using two regional samples of preschool children aged 3 to 5.5 years (Ns of 61 and 70). Teacher ratings of social skills and problem behaviors were collected using the Preschool and Kindergarten Behavior Scales (PKBS; Merrell, 1994), and estimates of preschoolers' basic concept attainment were obtained using the individually administered Bracken Basic Concept Scale (BBCS; Bracken, 1984). Results indicated that preschoolers' adaptive learning behaviors were positively correlated with social skills and negatively associated with problem behaviors but were not significantly related to subsequent basic concept attainment. Four-week test-retest coefficients for the PLBS Total score and Competence Motivation, Attention/Persistence, and Attitude Toward Learning subscale scores were adequate. Results support the unique contribution of PLBS scores in understanding children's responses to learning activities in preschool classroom environments.

Generalizing Nigrescence Profiles

The two studies in this article examine the interpretability and generalizability of nigrescence profiles based on Cross Racial Identity Scale scores across different educational contexts. Study 1 participants ( N = 333) came from a predominantly White institution (PWI) and were grouped into six clusters labeled Afrocentric, multiculturalist, assimilated, immersion, low race salience, and miseducated variant. The two samples in Study 2 consisted of students from PWIs ( N = 314) and from historically Black colleges and universities (HBCUs; N = 306), respectively. Both PWI and HBCU participants were grouped into five clusters. Four of the six original clusters (assimilated, immersion, low race salience, and miseducated variant) replicated in both samples, and one (multiculturalists) replicated only in the PWI sample. The results indicate that there are generalizable racial identity profiles in the Black population. The authors discuss the implications of the findings.

Diverging Academic Paths in Rural Caribbean Village Children

In many Caribbean countries, secondary school positions are rationed to children who pass an examination they take at age 12. In St Vincent, children from villages are more likely to fail this examination, the Common Entrance Examination, than are urban children. Despite being a major determinant in children's futures, little within community research has been conducted on factors influencing children's ability to pass this examination. We analysed longitudinal data from village children to identify accurate and early predictors of CEE passes.

We included 66 children (35 boys, 31 girls). Academic scores and achievement test scores assessed academic performance. The Raven Coloured Progressive Matrices assessed abstract reasoning. A modified version ofthe Revised Behaviour Problem Checklist completed by teachers assessed behaviour problems. A modified version of the HOME Inventory and other measures assessed home environment.

Discriminant analyses indicated that children's achievement, aca demic and behaviour problems and cognitive abilities as early as age 8 can predict later examination success or failure. Of these variables, achievement and academic performance were the most significant contributors. Results suggest that children's academic paths are estab lished by at least age 8 (Grade 3) and that children diverge academically and cognitively over the primary school years. Interventions designed to reduce the rural/urban gap in secondary school admissions may be more effective if started by age 8.

Learning Behaviours, Attention and Anxiety in Caribbean Children

Research suggests learning-related behaviours, anxiety and attention may influence academic performance. This research, however, has been limited to children from industrialized countries. Studies of children in developing countries have usually concentrated on children's cognitive abilities and home background. Contributions of learning behaviours, anxiety, attention problems, cognitive ability and home background to the academic performance of village children (N = 61; ages 6-12) on St Vincent, the West Indies, were investigated. Teachers provided academic scores and rated children using the Learning Behaviours Scale and using a modified version of the Revised Behaviour Problem Checklist. Children's cognitive ability was assessed using the Raven Colored Progressive Matrices and their academic skills were assessed using a locally standardized achievement test. Stimulating home experiences, caregiver involvement, affluence and caregiver education were assessed using the MC-HOME Inventory and by interviews. Hierarchical regression indicated that anxiety, attention and learning-related behaviours explain 32-35 percent of the variance in academic scores. In contrast, home background and cognitive ability

The MAL-ED cohort study: methods and lessons learned when assessing early child development and caregiving mediators in infants and young children in 8 low- and middle-income countries

More epidemiological data are needed on risk and protective factors for child development. In The Etiology, Risk Factors and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health and Development (MAL-ED) cohort study, we assessed child development in a harmonious manner across 8 sites in Bangladesh, Brazil, India, Nepal, Pakistan, Peru, South Africa, and Tanzania. From birth to 24 months, development and language acquisition were assessed via the Bayley Scales of Infant and Toddler Development and a modified MacArthur Communicative Development Inventory. Other measures were infant temperament, the child's environment, maternal psychological adjustment, and maternal reasoning abilities. We developed standard operating procedures and used multiple techniques to ensure appropriate adaptation and quality assurance across the sites. Test adaptation required significant time and human resources but is essential for data quality; funders should support this step in future studies. At the end of this study, we will have a portfolio of culturally adapted instruments for child development studies with examination of psychometric properties of each tool used.

Factor Structure of Scores from the Conners' Rating Scales-Revised Among Nepali Children

This study used exploratory and confirmatory factor analyses to examine the structures of scores from the Conners' Teacher and Parent Rating Scales-Revised (CTRS-R and CPRS-R, respectively; Conners, 1997). The scales were administered to 1,835 parents and 1,387 teachers of children in Nepal's Sarlahi district - a region where no other measures of child psychopathology have been studied. With a Nepali sample, the findings indicate that reduced two factor models for the Conners' scales are superior to the models identified in the scale development research. The hyperactivity and inattention factors were comparable to what has been identified in prior research, while other factors (e.g., social problems) differed substantially. Implications for use of the Conners' scales in Nepal and cross cultural issues in the assessment of ADHD symptoms are discussed.

Postpartum depressive symptoms across time and place: structural invariance of the Self-Reporting Questionnaire among women from the international, multi-site MAL-ED study

BACKGROUND

The Self-Reporting Questionnaire (SRQ) is a screening instrument that has been shown to be an effective measure of depression in postpartum women and is widely used in developing nations.

METHODS

The SRQ was administered to 2028 mothers from eight nations at two time points: one and six months postpartum. All data were obtained from the Interactions of Malnutrition and Enteric Infections: Consequences for Child Health and Development (MAL-ED) study. The sample included women from MAL-ED sites in Bangladesh, Brazil, India, Nepal, Pakistan, Peru, South Africa, and Tanzania. This study examined three aspects of validity of SRQ scores including (a) structural validity, (b) cross-cultural invariance, and (c) invariance over time.

RESULTS

A 16-item, one-factor structure with items reflecting somatic symptoms removed was deemed to be superior to the original structure in this postpartum population. Although differential item functioning (DIF) across sites was evident the one-factor model was a good fit to the data from seven sites, and the structure was invariant across the one- and six-month time points.

LIMITATIONS

Findings are based on data from self-report scales. No information about the clinical status of the participants was available.

CONCLUSIONS

Overall, findings support the validity of a modified model of the SRQ among postpartum women. Somatic symptoms (e.g., headaches, not sleeping well) may not reflect internalizing problems in a postpartum population. Implications for researchers and practitioners are discussed.

Making research real: embedding a longitudinal study in a taught research course for undergraduate nursing students

Learning how and why scholarly research underpins and informs professional nursing practice is a continual challenge for undergraduate nursing students. They find the language and methods of research to be unfamiliar and unsettling. The work of educators thus becomes the process of breaking down barriers to students' understanding of research processes and application. Such work is increasingly important in the current era of evidence based practice, where students must be competent in sourcing, critiquing and applying research to meet real clinical questions. In response, as lecturers who taught the course, Research for Health Professionals, we have reinvented how research is taught to second year undergraduate students. This article outlines our creative approach to facilitate students learning research theory and methodology by conducting a "real-life" research study in a local retirement community.

Preschool micronutrient supplementation effects on intellectual and motor function in school-aged Nepalese children

OBJECTIVE

To examine intellectual and motor functioning of children who received micronutrient supplementation from 12 to 35 months of age.

DESIGN

Cohort follow-up of children 7 to 9 years of age who participated in a 2 × 2 factorial, placebo-controlled, randomized trial from October 2001 through January 2006.

SETTING

Rural Nepal.

PARTICIPANTS

A total of 734 children 12 to 35 months of age at supplementation and 7 to 9 years of age at testing.

INTERVENTIONS

Children received iron plus folic acid (12.5 mg of iron and 50 μg of folic acid); zinc (10 mg); iron plus folic acid and zinc; or placebo.

MAIN OUTCOME MEASURES

Intellectual, motor, and executive function.

RESULTS

In both the unadjusted and adjusted analyses, iron plus folic acid supplementation had no effect overall or on any individual outcome measures being tested. In the unadjusted analysis, zinc supplementation had an overall effect, although none of the individual test score differences were significant. In the adjusted analysis, the overall difference was not significant.

CONCLUSION

In rural Nepal, we found that iron plus folic acid or zinc supplementation during the preschool years had no effect on aspects of intellectual, executive, and motor function at 7 to 9 years of age, suggesting no long-term developmental benefit of iron or zinc supplementation during 12 to 35 months of age.

Prenatal micronutrient supplementation and intellectual and motor function in early school-aged children in Nepal

CONTEXT

Iron and zinc are important for the development of both intellectual and motor skills. Few studies have examined whether iron and zinc supplementation during gestation, a critical period of central nervous system development, affects children's later functioning.

OBJECTIVE

To examine intellectual and motor functioning of children whose mothers received micronutrient supplementation during pregnancy.

DESIGN, SETTING, AND PARTICIPANTS

Cohort follow-up of 676 children aged 7 to 9 years in June 2007-April 2009 who had been born to women in 4 of 5 groups of a community-based, double-blind, randomized controlled trial of prenatal micronutrient supplementation between 1999 and 2001 in rural Nepal. Study children were also in the placebo group of a subsequent preschool iron and zinc supplementation trial.

INTERVENTIONS

Women whose children were followed up had been randomly assigned to receive daily iron/folic acid, iron/folic acid/zinc, or multiple micronutrients containing these plus 11 other micronutrients, all with vitamin A, vs a control group of vitamin A alone from early pregnancy through 3 months postpartum. These children did not receive additional micronutrient supplementation other than biannual vitamin A supplementation.

MAIN OUTCOME MEASURES

Children's intellectual functioning, assessed using the Universal Nonverbal Intelligence Test (UNIT); tests of executive function, including go/no-go, the Stroop test, and backward digit span; and motor function, assessed using the Movement Assessment Battery for Children (MABC) and finger-tapping test.

RESULTS

The difference across outcomes was significant (Bonferroni-adjusted P < .001) for iron/folic acid vs control but not for other supplement groups. The mean UNIT T score in the iron/folic acid group was 51.7 (SD, 8.5) and in the control group was 48.2 (SD, 10.2), with an adjusted mean difference of 2.38 (95% confidence interval [CI], 0.06-4.70; P = .04). Differences were not significant between the control group and either the iron/folic acid/zinc (0.73; 95% CI, -0.95 to 2.42) or multiple micronutrient (1.00; 95% CI, -0.55 to 2.56) groups. In tests of executive function, scores were better in the iron/folic acid group relative to the control group for the Stroop test (adjusted mean difference in proportion who failed, -0.14; 95% CI, -0.23 to -0.04) and backward digit span (adjusted mean difference, 0.36; 95% CI, 0.01-0.71) but not for the go/no-go test. The MABC score was lower (better) in the iron/folic acid group compared with the control group but not after adjustment for confounders (mean difference, -1.47; 95% CI, -3.06 to 0.12; P = .07). Finger-tapping test scores were higher (mean difference, 2.05; 95% CI, 0.87-3.24; P = .001) in the iron/folic acid group.

CONCLUSION

Aspects of intellectual functioning including working memory, inhibitory control, and fine motor functioning among offspring were positively associated with prenatal iron/folic acid supplementation in an area where iron deficiency is prevalent.

The Factor Structure of Preschool Learning Behaviors Scale Scores in Peruvian Children

The factor structure of the Escala de Conductas de Aprendizaje Preescolar (ECAP), a Spanish translation of the Preschool Learning Behaviors Scale (PLBS), was examined in this study. Children aged 2 to 6 years ( N = 328) enrolled in public and private preschools in the Republic of Peru were rated by classroom teachers on the frequency of observable, learning-related behaviors using the ECAP. Exploratory factor analyses identified three underlying dimensions of the scale: competence motivation, effortful strategy/flexibility, and attention. The three factor scores exhibited internal reliability coefficients above .70, and the alpha was .92 for the total score.

The factor structure of The Fear Survey Schedule for Children--II in Trinidadian children and adolescents

Part of understanding normal and abnormal fear in children and adolescents is having knowledge of how they acquire fears and of how fears change across development. One way to examine the relative contributions of heredity and environment to the experience of fear is to study fear across cultures. The Fear Survey Schedule for Children-II (FSSC-II; Gullone, E., & King, N. J. (1992). Psychometric evaluation of a revised fear survey schedule for children and adolescents. Journal of Child Psychology and Psychiatry, 33, 987-998) is one measure that has some evidence for cross-cultural validity. The present analysis examined the factor structure of the FSSC-II scores of 884 Trinidadian children and adolescents. Factor consistency across age, sex, and nationality (Trinidadian and American) was examined by calculating the coefficients of congruence for each pair of conceptually similar factors. Results indicated a five-factor structure for the overall sample. Although the solution was conceptually similar to those reported in other studies that used versions of the FSSC, the obtained structure was not congruent across age, sex, or nationality.

A guide to child nonverbal IQ measures

This guide provides a basic overview of 16 child nonverbal IQ measures and uses a set of specified criteria to evaluate them in terms of their psychometric properties. In doing so, the goal is neither to validate nor to criticize current uses of IQ but to (a) familiarize clinicians and investigators with the variety of nonverbal IQ measures currently available, (b) highlight some of the important distinctions among them, and (c) provide recommendations for the selection and interpretation of nonverbal IQ measures.

Empirical fear profiles among American youth

Fears among children can range from relatively innocuous fears of simple objects to significant phobias that affect youths' everyday functioning in the home, school, or community environments. This study investigated empirically derived fear profiles among American youth ages 7-19 (N=556). Based upon youths' scores on the 5 factors of the Fear Survey Schedule for Children-II (FSSC-II; Burnham & Gullone (Behav Res Ther, 35, 1997)), multistage Euclidean grouping was applied and produced 5 replicable fear cluster profiles with unique contours. Logistic regression odds ratios revealed specific associations of profile group membership with demographic characteristics such as child age, sex, and ethnicity.

What patient characteristics make clinicians recommend brief treatment?

OBJECTIVE

Assessing self-rated items that might have an impact on clinicians recommending brief treatment (BT) over unlimited or long-term treatment (ULT).

METHOD

On the basis of patient self-report data we compared patients referred by clinicians to BT (n=71) with those referred to ULT (n=145).

RESULTS

The final multiple logistic regression model indicates that the chance of being allocated to BT increases with: more satisfaction with support, higher self-esteem, primary education or less, and high desire for support as an intervention. With regard to desire to confess in treatment, low and high scores make the chance of being allocated to BT lower. This is also the case for daily hassles. Finally, some specific target complaints, in particular anxiety, lower the chance of being allocated to BT.

CONCLUSION

Using data about patient's complaints and symptoms, stress and support, personality and coping, and request for type of intervention, we built a regression-model that classified 80% of the patients correctly with regard to allocation to BT or ULT.

Diagnostic utility of the Learning Disability Index

The Learning Disability Index (LDI) is one of many diagnostic indicators proposed for the identification of students with learning disabilities that relies on patterns of performance on cognitive tests. The LDI is hypothesized to relate to students' specific neuropsychological deficits. The present study investigated the diagnostic utility of the LDI with the third edition of the Wechsler Intelligence Scale for Children by comparing students previously diagnosed with learning disabilities (n = 2,053) to students without learning disabilities (n = 2,200). Subsamples of youth with specific reading (n = 445) and math (n = 168) disabilities permitted further assessment of the efficacy of the LDI. Receiver operating characteristic (ROC) curves revealed that the LDI resulted in a correct diagnostic decision only 55% to 64% of the time. These results demonstrate that the LDI is not a valid diagnostic indicator of learning disabilities.

Learning-related behaviours versus cognitive ability in the academic performance of Vincentian children

BACKGROUND

The few studies of children's academic performance in developing countries have largely focused on effects of early risks and cognitive ability and usually neglected other factors such as attention and anxiety. Previously, we reported that scores on the Learning Behaviour Scale (LBS) and the Revised Behaviour Problem Checklist (RBPC) were correlated with academic scores and achievement test scores for village children in St Vincent, the West Indies.

AIMS

We examined the stability of LBS and RBPC scores and their ability to predict academic and achievement scores in the same population.

SAMPLE

Vincentian village children, ages 6-12, participated in the study: 65 participated in the one-year sample and 68 participated in the two-year sample.

METHOD

Children completed a curriculum-based achievement test and the Raven Coloured Progressive Matrices. Teachers completed the LBS and an adjusted RBPC and reported children's academic scores in 1998 and 1999.

RESULTS

LBS scores were stable over one year and RBPC scores were stable over two years. LBS, RBPC, and Raven scores predicted achievement and academic scores. For both academic scores and achievement test scores, the greatest improvement in prediction came when the RBPC's attention and anxiety subscales were added to regression models.

CONCLUSIONS

Results provide additional support for the finding that Caribbean village children's academic performance is greatly influenced by attention and anxiety problems, not just their cognitive ability. Despite cultural differences, LBS and RBPC scores were as predictive of academic performance in this population as in American populations. The best way to improve academic performance for these children may be to reduce attention problems.
