Description:
The current study used latent profile analysis (LPA) to ascertain distinct groups of children with ADHD (N = 701) in terms of performance on working memory (WM) tasks that tapped visuospatial sketchpad, spatial central executive, and verbal central executive functions. It compared the WM performances of these classes with a clinical comparison group (N = 59). The participants' age ranged from 7 to 16 years (586 males, 71 females). The results of the LPA supported three classes. For all three WM tasks, class 1 (N = 196) had more difficulties than classes 2 (N = 394) and 3 (N = 111), and the clinical comparison group. Class 2 had more difficulties than class 3 and the clinical comparison group, and there was no difference between class 3 and the clinical comparison group. Class 1 had lower IQ and academic abilities, and relatively more individuals with depressive disorders. The implications of the findings for understanding ADHD and its treatment are discussed.

BACKGROUND: This study evaluated the measurement invariance and agreement across parent and teacher ratings of the DSM-IV-TR oppositional defiant disorder (ODD) symptoms. METHOD: Malaysian parents and teachers of 934 children (between 6 and 11 years of age) completed rating scales comprising the ODD symptoms. RESULTS: Findings showed support for full measurement invariance (configural, metric and thresholds). Additional results indicated low parent-teacher agreement for all symptoms. DISCUSSION: The theoretical and clinical and implications of these findings are discussed.
Description:
The study used multiple-group confirmatory factor analysis (CFA) and multiple indicators multiple causes (MIMIC) procedures to examine the measurement and construct equivalencies for father and mother ratings of ADHD symptoms, recoded as binary scores. Fathers (N = 387) and mothers (N = 411) rated their primary school-aged children on the Disruptive Behavior Rating Scale (Barkley & Murphy, 1998). For the multiple-group CFA analyses, the results involving differences in practical fit indices supported full measurement and construct equivalencies, whereas the chi-square difference test showed lack of equivalency in five symptoms for factor loadings, four symptoms for error variance, and the variance and mean scores for the hyperactivity-impulsivity factor. For the MIMIC analyses, six symptoms lacked equivalency for thresholds. These findings extend existing data in this area. The theoretical, psychometric and clinical implications of the findings are discussed.
Description:
The graded response model, which is based on item response theory, was used to evaluate the psychometric properties of adult self-ratings (N = 852) of the attention deficit/hyperactivity disorder inattention, hyperactivity, and impulsivity symptoms presented in the Current Symptoms Scale. This scale has four ordered response categories. The results for the discrimination parameters showed that all symptoms were generally good for discriminating their respective latent traits. For virtually all symptoms, their threshold values showed that they were especially good at representing the appropriate traits from around the mean trait level onward. The item information function values for most symptoms indicated reasonable reliability from approximately the mean trait level onward. All these findings are new and extend existing psychometric information for adult self-ratings of the attention deficit/hyperactivity disorder symptoms in the Current Symptoms Scale.
Description:
OBJECTIVE: ADHD and Hyperkinetic Disorder (HKD) have the same 18 symptoms, covering inattention (IA), hyperactivity (HYP), and impulsivity (IMP). This study was aimed at providing descriptive scores for the different symptom groups in these disorders and how these scores varied by age and gender, the percentages of individuals meeting the symptom thresholds for the different ADHD types and HKD, the factor structure, and gender invariance of these symptoms in adults. METHOD: To accomplish this, 852 adults provided self-ratings for a scale comprising the 18 ADHD/HKD symptoms. RESULTS: The findings showed that age and gender had minimal effects on the ADHD symptoms. Also, in terms of symptom counts, 2% had HKD and 6.3% had ADHD (inattentive = 1.6%, hyperactive-impulsive = 2.7%, and combined type = 2.0%). Confirmatory factor analysis (CFA) provided most support for the three-factor HKD model, involving separate factors for the IA, HYP, and IMP symptoms. This model showed full measurement invariance across gender. CONCLUSION: The theoretical and clinical implications of the findings are discussed.
Description:
The current study used confirmatory factor analysis (CFA), latent profile analysis (LPA), and factor mixture modeling (FMM) to examine the co-occurrence of the childhood syndromes using the Child Behavior Checklist (CBCL) and Teacher Report Form (TRF). Parents and teachers completed the CBCL and TRF, respectively, for a clinic-referred sample of 720 children, ages 7-12 years. For the CBCL, the analyses indicated most support a 2-class 2-factor FMM, and for the TRF, there was most support for a 2-class 3-factor model. The classes were all syndromes at average levels and all syndromes at high levels. The findings indicate high syndrome co-occurrence. The implications of the findings for understanding syndrome co-occurrence in the CBCL and TRF, theories of syndrome co-occurrence, and the clinical use of the CBCL and TRF are discussed.
Description:
The short version of the Parent-Parental Acceptance-Rejection Questionnaire (Parent-PARQ/S; Rohner, 2005) measures current parental acceptance and rejection of their children. It has four scales measuring coldness/lack of affection, hostility/aggression, indifference/neglect, and undifferentiated rejection. This study examined the psychometric properties of the Parent-PARQ/S. Design . A sample of 1,382 Malaysian parents completed the Parent-PARQ/S. Results . Confirmatory factor analysis supported a slightly modified version of the proposed 4-factor model (i.e., item number 13 reallocated to coldness/lack of affection factor instead of the proposed indifference/neglect factor).

Description:
We report a meta-analysis of up to 40 data sets that examined the personality dimensions in the Five-Factor Model (FFM) and the integrated Five-Factor Model (IFFM) in relation to ADHD symptom domains of inattention (IA) and hyperactivity/impulsivity (HI). The IFFM incorporated the dimensions of other personality models (in particular, those of Eysenck, Tellegen, and Cloninger, as well as the FFM). Major findings were: (1) IA and HI were both associated with low conscientious inhibition/conscientiousness, and low agreeable inhibition/agreeableness, and with high negative emotionality/neuroticism; (2) conscientious inhibition and conscientiousness were more strongly related to IA than HI; (3) agreeable inhibition and agreeableness were more strongly related to HI than IA; and (4) the association of conscientious inhibition and conscientiousness with HI was moderated by age group and source from where participants were recruited (associations were stronger in children than adults, and clinical samples than community samples). These findings are discussed in relation to single and multiple pathway theories, underlying factors and processes for the personality-ADHD link, and clinical implications.
Description:
The present study examined measurement invariance of the Center for Epidemiologic Studies Depression Scale (CES-D) in community groups of Australian heterosexual men (N = 1106), heterosexual women (N = 2111), gay men (N = 527), and lesbians (N = 712). Confirmatory factor analysis of CES-D item scores supported the theorized oblique 4-factor model. There was support for full measurement invariance across the 4 groups, based on differences in approximate fit indices. In contrast there was support for only partial invariance when the chi-square difference test was applied. Lack of invariance was mostly for depressed affect and somatic symptom items, with noninvariant somatic symptom items showing consistently high factor loadings and thresholds among lesbians compared with the other groups. The findings are discussed in relation to the use of the CES-D, the relevance of different depression symptoms to how depressions is experienced by the different gender and sexual orientation groups, and gender role socialization and minority sexual orientation theories.
