Background: Behavioural problems in individuals with intellectual disabilities have a negative impact on them. Limited assessment measures exist in Spain. This study aimed to validate the Behavior Problems Inventory--Short Form (BPI-S) in the Spanish population by examining its psychometric properties and factorial structures. Method: This study…

Background: Walk tests are common gait speed and endurance assessments. Shorter test versions could benefit adults with intellectual disability. Thus, the concurrent validity of shorter tests was studied. Methods: Thirty-five adults with mild to moderate intellectual disability, aged 21-64 years, were assessed with the 4-m walk test, 10-m walk…

Background: Since the DSM-5, adaptive functioning has taken a prominent place in the classification of intellectual disability (ID). The ADAPT was developed to assess adaptive skills in individuals with ID. Method: A total of 2,081 ADAPTs from clients with suspected ID or borderline intellectual functioning and 129 ADAPTs from people from the…

Background: The aims of the current study were to adapt a version of the MET for people with intellectual disabilities and assess its ecological and construct validity. Material and Methods: Using a correlational design, 40 participants with intellectual disabilities were invited to complete a battery of neuropsychological assessments and the…

Background: Neuropsychological tests of memory are believed to offer the greatest sensitivity at identifying people at the risk of developing dementia. There is a paucity of standardized and appropriate neuropsychological assessments of memory for adults with an intellectual disability. This study examines how adults with an intellectual…

Background: This paper examines the development and psychometric characteristics of three instruments about end of life, designed for use with adults with intellectual disability (ID). Respectively, the instruments assess understanding of the concept of death, end-of-life planning, and fear of death. Methods: Part 1: instruments were developed or…

Background: Family Quality of Life (FQOL) is an important construct in the Intellectual Disabilities field. Several measures exist, including one developed by an international group, the Family Quality of Life Survey-2006 (FQOLS-2006; Brown et al.2006). However, the psychometric properties of this measure have yet to be fully investigated. This…

Background: The aim of the study was to explore the validity of the social-moral awareness test (SMAT) a measure designed for assessing socio-moral rule knowledge and reasoning in people with learning disabilities. Comparisons between Theory of Mind and socio-moral reasoning allowed the exploration of construct validity of the tool. Factor…

Background: The Manchester Attachment Scale-Third party observational measure (MAST) was developed to assess secure attachment style for adults with intellectual disabilities. The psychometric properties of the MAST were examined. Materials and Methods: Professional carers (N = 40) completed the MAST and measures related to the construct of…

Background: People with Down Syndrome are at significant risk of developing Alzheimer's disease as they get older and early assessment, diagnosis and intervention is essential. Neuro-psychological measures of cognitive functioning play an important part in the assessment process. The aim of the present study was to examine the concurrent criterion…

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…

Background: Although high-structured elicitation tasks have been shown to be efficient means to sample communication in children with intellectual disabilities, their validity and reliability remain to be evaluated. The aims of this study were threefold: (i) to evaluate the eliciting potential, (ii) to examine the utterance forms of…

Background: Psychometric properties of three functional assessment rating scales were compared for three types of target behaviours [self-injurious behaviour (SIB), stereotypic behaviour and aggressive/destructive behaviour]. Materials and method: The "Questions about Behavioural Function" (QABF), the "Functional Assessment for…

Background: There is an urgent need for developing reliable, valid and practical instruments that assess and classify the support needed by persons with disability to function in their chosen living, working and social environments. I-CAN is an instrument that addresses the frequency and level of support needed (not individual skills or deficits)…
