    Welham J, Scott J, Williams GM, Najman JM, Bor W, O'Callaghan M, McGrath J. The antecedents of non-affective psychosis in a birth-cohort, with a focus on measures related to cognitive ability, attentional dysfunction, and speech problems. Objective:, Adults with non-affective psychosis show subtle deviations in a range of developmental trajectories as children and adolescents. Method:, Based on a birth-cohort (n = 3801), we examined the Peabody Picture Vocabulary Test (PPTV) at age 5, and Raven's Standard Progressive Matrices (RSPM) and Wide Range Achievement Test reading scale (WRAT-R) at age 14. Items related to speech problems and attentional dysfunction were available from maternal- or self-report. At age 21, we identified 60 cohort members who were screen-positive for non-affective psychosis (SP-NAP). Results:, Impaired performance on the PPVT and RSPM (but not WRAT-R) predicted SP-NAP for males only. Male cohort members in the highest quartile for attentional dysfunction at ages 5 and 14 were about 5,8 times more likely to develop SP-NAP. SP-NAP in males was significantly associated with speech problems at age 14. Conclusion:, Males who develop non-affective psychoses have subtle impairments in cognitive capacity prior to the development of their psychotic disorder. [source]

    Comparison of the Peabody Picture Vocabulary Test,Third Edition and Wechsler Adult Intelligence Scale,Third Edition with university students

    This study examined the relationship between the Peabody Picture Vocabulary Test,Third Edition (PPVT-III) and Wechsler Adult Intelligence Scale,Third Edition (WAIS-III) using 40 adults who ranged in age from 18 to 41 (mean age of 22 years). Participants were administered the PPVT-III and WAIS-III in counterbalanced fashion to control for order effects. Results revealed that the PPVT-III score was related to the WAIS-III Verbal IQ (VIQ) and Full Scale IQ (FSIQ) scores but unrelated to the Performance IQ (PIQ) score. In addition, analyses indicated that, while there were no significant differences between the PPVT-III score and WAIS-III mean FSIQ and PIQ scores, the PPVT-III mean score was significantly lower than the WAIS-III VIQ. Further analysis indicated that the PPVT-III adequately estimated WAIS-III FSIQ and VIQ scores for participants who were classified as Average or High Average on the WAIS-III. However, for participants in the Superior range, the PPVT-III tended to underestimate FSIQ and VIQ scores by approximately 10 points. © 2001 John Wiley & Sons, Inc. J Clin Psychol 57: 417,422, 2001.

    The effect of breastfeeding on child development at 5 years: A cohort study

    Objective: It is uncertain to what degree the relationship between breastfeeding and later cognitive development is a true biological effect, or is confounded by psychosocial factors. The study aim was to further investigate this relationship and the effect of duration of breast feeding on cognitive development. Methods: A total of 3880 children were followed from birth. Breastfeeding duration was measured by questionaire at 6 months of age and a Peabody Picture Vocabulary Test Revised (PPVT-R) was administered at 5 years. PPVT-R scores were adjusted for the effects of a large array of biological and psychosocial confounders. The relationship between breastfeeding and the mean PPVT-R scores were examined using analysis of variance and multiple linear regression. Results: A strong positive relationship was demonstrated between breastfeeding and the PPVT-R scores with increasing scores with increased duration of breastfeeding. After adjusting for a wide range of biological and social factors, the adjusted mean for those breastfed for 6 months or more was 8.2 points higher for females and 5.8 points for males when compared to those never breastfed. Conclusion: These findings suggest a significant benefit to child development is conferred by breastfeeding and is related independently to longer periods of breastfeeding. [source]

    The MTHFR 677C,T polymorphism and behaviors in children with autism: exploratory genotype,phenotype correlations

    AUTISM RESEARCH, Issue 2 2009
    Robin P. Goin-Kochel
    Abstract New evidence suggests that autism may be associated with (a) varied behavioral responses to folate therapy and (b) metabolic anomalies, including those in folate metabolism, that contribute to hypomethylation of DNA. We hypothesized that children with autism who are homozygous for the MTHFR 677 T allele (TT) and, to a lesser extent those with the CT variant, would exhibit more behavioral problems and/or more severe problematic behaviors than homozygous wild-type (CC) individuals because of difficulties in effectively converting 5,10-MTHF to 5-MTHF. Data from the Autism Genetic Resource Exchange (AGRE) collection were analyzed for all children who met strict criteria for autism per the Autism Diagnostic Interview,Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) and who had been genotyped for the 677 C to T MTHFR polymorphism (n=147). Chi-square tests, logistic regression, and one-way ANOVAs were used to determine whether differences existed among MTHFR genotypes for specific behaviors on the ADI-R and indices for level of functioning. Exploratory results indicated four behaviors from the ADI-R that were more common and problematic (95% CI) among those with at least one copy of the T allele as compared to homozygous wild-type individuals: direct gaze, current complex body movements, a history of self-injurious behavior, and current overactivity (ORs=2.72, 2.33, 2.12, 2.47, respectively). No differences existed among genotypes for level of functioning as measured with the Peabody Picture Vocabulary Test,Third Edition, Ravens Colored Progressive Matrices, or the Vineland Adaptive Behavior Scales. Findings call for further investigation of the relationship between folate metabolism and problem behaviors among children with autism. [source]
