Factor structure and measurement invariance of the Childhood Executive Functioning Inventory (CHEXI) across parents and teachers in Portuguese children.

The Childhood Executive Functioning Inventory (CHEXI) is a rating scale that evaluates everyday behaviors associated with executive functions in children. This study aimed to investigate the factor structure and the measurement invariance across parents and teachers of the CHEXI in a sample of 279 Portuguese typically developing children (6 to 12 years old,  = 160 girls and  = 119 boys). Most studies only analyzed the original two-factor model, and the few that investigated the four-factor model found a nearly identical fit between both factor structures.

BRIEF-A: Factor structure and measurement invariance across self-report and informant forms.

Objective: This study analyzes the psychometric properties of the two forms (self-report and informant) of the Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A) in a sample of healthy Portuguese adults.

Method: The participants were 608 adults, 304 of whom answered the self-report form (ages 18-59; 137 male and 167 female) and 304 who answered the informant form (ages 18-70; 110 male and 194 female).

Results: The internal consistency for the indexes and the Global Executive Composite was very good (≥.

Factor structure and measurement invariance of the BRIEF2 Parent Form across gender in a Portuguese sample.

This study aimed to investigate the factor structure and the measurement invariance across gender of the BRIEF2 Parent Form in Portuguese typically developing children. Participants were 700 typically developing children ( = 352 girls and  = 348 boys) aged 6-16 years. Confirmatory factor analysis was used to test five competing factor models.

Needs of older people with intellectual disabilities: variables influencing inter-respondent (client vs staff) agreement.

The importance of understanding the needs of older people with intellectual disabilities (IDs) is obvious, but the research available is limited. This study identifies the self-reported needs of older adults with IDs and compares them with staff reported needs regarding the same older adults with ID, therefore specifying and explaining agreements and disagreements. The needs of 96 older adults with IDs were assessed through the Inventory of Identification of Needs (informant and self-report versions).

Memory and linguistic/executive functions of children with borderline intellectual functioning.

Children with Borderline Intellectual Functioning (BIF) have received a minimal amount of research attention and have been studied in conjunction with Intellectual and Developmental Disabilities. The present study intends to broaden the knowledge of BIF, by analyzing domains such as verbal memory and visual memory, as well as tasks that rely simultaneously on memory, executive functions, and language. A cross-sectional, comparison study was carried out between a group of 40 children with BIF (mean age = 10.

Factor Structure and Measurement Invariance of the Coimbra Neuropsychological Assessment Battery (BANC).

Objective: This study aimed to investigate the factor structure of the Coimbra Neuropsychological Assessment Battery (BANC), which is an individually administered battery designed to assess a wide range of neurocognitive functions in children.

Method: Using the standardization sample of the BANC, a confirmatory factor analysis and a multiple-group analysis were conducted to examine the factor structure and the measurement invariance of three main domains (Memory, Language, and Attention/Executive Functions) in 833 children aged 7-15 years.

Results: Consistent with the BANC's conceptualization, the three-correlated-factor model demonstrated the most adequate fit to the data.

Validating the Preschool and Kindergarten Behavior Scales-2: Preschoolers with autism spectrum disorders.

Social skills deficits and some behavior problems are a well-established issue in preschoolers with autism spectrum disorder (ASD). However, most of the studies available analyze social skills or behavior problems of children with ASD, but not both. The present study intends to compare the social skills and behavior problems of 32 preschoolers with ASD paired with 32 typically developing preschoolers, as evidence of validity of the Portuguese version of the Preschool and Kindergarten Behavior Scales - Second Edition (PKBS-2).

Psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q).

Background: This study analyzes the psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q; Quality of Life Questionnaire Manual - 1993 Manual and 2004 Revision. 2004, IDS Publishing Company, Worthington, OH; Schalock & Keith 2004).

Method: The analysis of the factorial structure was carried out on a sample of 304 adults with intellectual disabilities, through the use of confirmatory (CFA) and exploratory (EFA) factor analysis.

Rapid naming tests: developmental course and relations with neuropsychological measures.

A Digits Rapid Automatized Naming (RAN) test and a Colors and Shapes Rapid Alternating Stimulus (RAS) test were administered to 904 Portuguese, normally achieving children (ages 7 to 15), in order to examine these tests scores developmental course. The results showed that the two tests have slightly different developmental trajectories. In addition, the two tests associations with a large number of neuropsychological measures were determined in three age groups (7-9 years, n = 301; 10-12 years, n = 299; 13-15 years, n = 304).
