Effects of Differential Item Functioning on Examinees' Test Performance and Reliability of Test

Simulations were conducted to examine the effect of differential item functioning (DIF) on measurement consequences such as total scores, item response theory (IRT) ability estimates, and test reliability in terms of the ratio of true-score variance to observed-score variance and the standard error of estimation for the IRT ability parameter. The objective was to provide bounds of the likely DIF effects on these measurement consequences. Five factors were manipulated: test length, percentage of DIF items per form, item type, sample size, and level of group ability difference. Results indicate that the greatest DIF effect was less than 2 points on the 0 to 60 total score scale and about 0.15 on the IRT ability scale. DIF had a limited effect on the ratio of true-score variance to observed-score variance, but its influence on the standard error of estimation for the IRT ability parameter was evident for certain ability values.

Development of the Cognitive Dysfunction Questionnaire (CDQ) in a population based sample

The study reports on the development of a questionnaire for assessment of adult cognitive dysfunction (CDQ). Participants in a population-based sample (65±15 years, N=370) responded to a 90-item pilot version covering multiple aspects of memory/cognition. Based on exploratory principal components analyses and correlations with criterion measures of cognitive functioning (MMSE, Block Design, semantic/episodic memory), 20 items loading on 6 components were selected for the final version of the questionnaire. Cronbach's α for the total score was 0.90. There was evidence of construct validity as judged by correlations between CDQ scores, objective cognitive measures, and a subjective memory measure (PRMQ). Discriminant validity was demonstrated by a low and non-significant correlation with depressive symptoms. Further evidence of construct validity was provided by correlations with age and educational attainment. In conclusion, the CDQ is promising as a self-rating screening tool for cognitive dysfunction, and will be the subject of further development and validation.     

Do Raven's Colored Progressive Matrices function in the same way in typical and clinical populations? Insights from the intellectual disability field

Standardized tests are used widely in comparative studies of clinical populations, either as dependent or control variables. Yet, one cannot always be sure that the test items measure the same constructs in the groups under study. In the present work, 460 participants with intellectual disability of undifferentiated etiology and 488 typical children were tested using Raven's Colored Progressive Matrices (RCPM). Data were analyzed using binomial logistic regression modeling designed to detect differential item functioning (DIF). Results showed that 12 items out of 36 function differentially between the two groups, but only 2 items exhibit at least moderate DIF. Thus, a very large majority of the items have identical discriminative power and difficulty levels across the two groups. It is concluded that RCPM can be used with confidence in studies comparing participants with and without intellectual disability. In addition, it is suggested that methods for investigating internal bias of tests used in cross-cultural, cross-linguistic or cross-gender comparisons should also be regularly employed in studies of clinical populations, particularly in the field of developmental disability, to show the absence of systematic measurement error (i.e. DIF) affecting item responses.     

急性脑梗死早期OCSP分型的临床应用评价

为了研究急性脑梗死早期OCSP（Oxfordshire Community Stroke Projet）分型的应用价值,连续收集首次发病的脑梗死患者326例,按OCSP分型分为完全前循环梗死（TACI）、部分前循环梗死（PACI）、腔隙性脑梗死（LACI）、后循环梗死（PCI）,入组后各亚型比较急性期神经功能缺损评分和结构影像学特征,3个月的病死率和日常生活活动（ADL）能力评分。显示,TACI大面积脑梗死占74．4％,PACI中等面积脑梗死占64．5%。LACI腔隙灶脑梗死占90％,POCI大面积脑梗死占22．7％,中等面积脑梗死占40.9％,小梗死占36.4％。急性期神经功能缺损以TACI最严重,PACI和POCI次之,LACI最轻,TACI与其他各型之间,PACI和POCI与LACI之间的差异均有极显著性意义（P〈0．0005）,PACI和POCI之间差异无显著性意义（P〉0．05）。TACI的病死率为44．2％,PACI为10．2%,POCI为18．2%赫,LACI为2．6％,TACI病死率与各型比较有极显著性意义（P〈0．01）.TAC13个月的ADL为重度依赖,POCI为中度依赖,另2个亚型均为轻度依赖,有极显著性意义（P〈0．005）。由此得出结论,OCSP分型与影像学有良好对应关系。不同的OCSP分型可以反映脑梗死急性期神经功能缺损的严重程度,OCSP分型有利于脑梗死急性期个体化治疗选择。     

Economic Pressure and Children's Psychological Functioning

We examined the mediating role of family dynamics (marital quality, parental depression) in the link between economic pressure and child psychological functioning using the data from the National Survey of Family and Households (NSFH). From the initial multiethnic probability sample, we used a subsample of 2998 parents with a focal child 5 to 17 years of age. We used structural equation modeling using AMOS 4.0 to test the model. The results indicated support for associations among economic pressure, marital quality, parental depression, parenting strategies and children outcomes. Economic pressure was associated with lower marital quality and higher depression. Higher conflict and psychological distress was associated with frequent use of harsh discipline techniques and lower psychological functioning in children.     

Social and non‐social measures of cognition for predicting self‐reported and informant‐reported functional outcomes in early psychosis

The main aim of this study was to investigate the individual contributions of neurocognitive and social‐cognitive domains to self‐reported and informant‐reported functional outcome in early psychosis. We also sought to further characterize the nature of cognitive impairments in this sample and explore the interrelationships between the social‐cognitive measures and how they correlate with measures of neurocognition and clinical symptoms. In this study, 70 patients (mean age: 24.1; 87.1% males) with primary psychotic disorder diagnosed in the previous 5 years were assessed on multiple neurocognitive (processing speed, attention, working memory, immediate verbal memory, delayed recall, visual reasoning, inhibition, planning, cognitive flexibility), and social‐cognitive domains (theory of mind (ToM), emotion recognition, attributional style, metacognitive overconfidence) as well as measures of clinical symptoms. Functional outcome was assessed with three self‐reports and two informant‐reports. On average, patients performed one or more SD below healthy controls on measures of delayed recall, ToM and metacognitive overconfidence. Emotion recognition and ToM were intercorrelated and correlated with multiple neurocognitive domains and negative symptoms. Attributional style correlated with positive symptoms. In the context of multiple variables, self‐reported functional outcomes were predicted by attributional style, whereas emotion recognition and immediate verbal memory predicted variance in informant‐reported community functioning. These results support the suggestion of a likely distinction between the predictive factors for self‐reported and informant‐reported functional outcome in early psychosis and suggest that consideration of self‐assessment of functional outcome is critical when attempting to evaluate the effects attributional style has on functional disability.     

Family Functioning,Family Structure,and Differentiation of Self in Heterosexual Spanish Couples: An Actor–Partner Analysis

This study used an actor–partner interdependence model to assess the relationship between differentiation of self and family functioning in a sample of 118 heterosexual Spanish couples, with additional attention to family structural correlates, including age of the children, number of children in the household, and educational level. Results showed a significant actor effect, with greater differentiation of self levels predicting better family functioning within individuals. Implications for mental health professionals regarding differentiation are provided.     

Multivariate base rates for the assessment of executive functioning among children and adolescents

This study provides observed base rates of low executive functioning test scores among healthy children and adolescents, stratifies those base rates by narrow intellectual functioning and age groupings, and provides normative classification ranges to aid the interpretation of performances on the Delis-Kaplan Executive Function System (D-KEFS) in clinical practice and research. Participants included 875 children and adolescents between 8 and 19 years old from the D-KEFS normative sample (48% male; 52% female). Among these participants, 838 had complete data and were included in the current study. The racial/ethnic composition of the sample was: White (73.7%), African American (12.4%), Hispanic (11.1%), and other racial/ethnic backgrounds (2.7%). The Overall Test Battery Mean (OTBM) and the prevalence of low scores at various clinical cut-offs were calculated for the 13 primary scores from the D-KEFS Trail Making Test, Verbal Fluency Test, and Color-Word Interference Test. The OTBM and base rates were also calculated separately for those scores reflecting executive functioning (n = 7) and processing speed (n = 6). Healthy children and adolescents commonly obtained low scores on the D-KEFS tests considered here. Younger age, lower estimated full-scale intelligence quotient, and more test scores interpreted were associated with a greater frequency of low scores. Clinicians and researchers are encouraged to consider these multivariate base rates when assessing and attempting to identify executive functioning impairment among children and adolescents with the D-KEFS.
