The MMPI-2 Restructured Clinical Scales in the assessment of posttraumatic stress disorder and comorbid disorders.

Study 1 included 1,098 men who completed the MMPI-2 and were assessed for a range of psychological disorders via structured clinical interview. Study 2 included 136 women who completed the MMPI-2 and were interviewed with the Clinician Administered Scale for PTSD. The utility of the RCSs was compared with that of the Clinical Scales (CSs) and the Keane PTSD (PK) scale. The RCSs demonstrated good psychometric properties and patterns of associations with other measures of psychopathology that corresponded to current theory regarding the structure of comorbidity. A notable advantage of the RCSs compared with the MMPI-2 CSs was their enhanced construct validity and clinical utility in the assessment of comorbid internalizing and externalizing psychopathology. The PK scale demonstrated incremental validity in the prediction of PTSD beyond that of the RCSs or CSs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The etiology of behavioral problems and competencies in very young twins.

Although genetic and environmental influences on behavior problems in middle childhood and adolescence have been well-studied, little is known about the etiology of behavior problems in very early childhood. The present study explores genetic and environmental contributions to individual differences in behavior problems and competences in an infant-toddler sample of twins. There were 1,950 twin pairs (mean age=23.8 months) who were rated by parents on the Infant-Toddler Social and Emotional Assessment. All four domains (Externalizing, Internalizing, Dysregulation, Competence) and 20 subscales-indices on the Infant-Toddler Social and Emotional Assessment displayed significant heritability. There were also substantial shared environmental influences operating on most of the domains and subscales. Compared with behavior problems, behavioral competencies were less heritable and more influenced by shared environments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A multicenter, randomized clinical trial of a cognitive remediation program for childhood survivors of a pediatric malignancy.

Survivors of childhood cancer whose malignancy and/or treatment involved the central nervous system may demonstrate a consistent pattern of neurocognitive deficits. The present study evaluated a randomized clinical trial of the Cognitive Remediation Program (CRP). Participants were 6- to 17-year-old survivors of childhood cancer (N = 161; 35% female, 18% Hispanic, 10% African American, 64% Caucasian, 8% other) who were at least 1 year off treatment and who manifested an attentional deficit. They were enrolled at 7 sites nationwide. Two thirds of the participants were randomly assigned to cognitive remediation. All participants were assessed using a battery of academic achievement/neurocognitive tests and parent/teacher measures of attention. The CRP resulted in parent report of improved attention and statistically significant increases in academic achievement. Effect sizes were modest but were comparable with those for other clinical trials of brain injury rehabilitation and for psychological interventions in general. The CRP is presented as a potentially beneficial treatment for many survivors of pediatric cancer. Long-term clinical significance remains unproven. Further work is needed to improve effect sizes and treatment compliance and to address the needs of other populations with pediatric brain injury.

Starch Swelling Power,Grain Hardness and Protein: Relationship to Sensory Properties of Japanese Noodles

The starch swelling power tests have been reported to be a promising method for predicting the eating quality of Japanese white salted noodles. The relationships between starch swelling power and noodle eating quality were examined for a range of commercial Australian-wheat cultivars from two growth seasons. Starch swelling power was found to be dependent on the cultivar, growth site and growth season of the wheat. Analyses of the first season's samples showed highly significant relationships between swelling power and most noodle quality parameters (r² = 0.16–0.45, p<0.01). the inclusion of wheat protein and wheat softness (PSI) with starch swelling power in multiple regression equations provided improved relationships to most noodle quality parameters (r² = 0.25–0.62, p<0.01). When tested on data from the second growth season, the predictions were useful, especially for the noodle parameters elasticity and eating quality.
