Characteristics of Young Adults with Autism Spectrum Disorder Performing Different Daytime Activities.

Daytime activity, in terms of engagement in an occupation or education, is highly important for individuals with autism spectrum disorder (ASD), regardless of their level of functioning. In this nationwide survey, the parents of young adults diagnosed with ASD in childhood (n = 1266) provided information about the current daytime activity of their child, as well as behavioral characteristics, comorbidity, history of schooling during primary and secondary school, and availability of support. The young adults without a regular daytime activity constituted approximately one-fifth of the sample and had more behavioral difficulties and comorbidities than young adults with a daytime activity. Intellectual disability, part-time job, history of schooling, including type of school, and availability of support were found to be associated with daytime activity.

Quality of life in adolescents and adults with autism spectrum disorder: Results from a nationwide Danish survey using self-reports and parental proxy-reports.

BACKGROUND: Quality of life (QoL) in individuals with autism spectrum disorder (ASD) is essential to investigate with regard to knowledge about factors of importance for QoL and concordance between self-reported and parental proxy-reported QoL. AIMS: This study investigated QoL in adolescents and adults with ASD using both self-reports and parental proxy-reports. METHODS: From a nationwide survey, 1738 individuals diagnosed with ASD in childhood, were included for this study. The individuals themselves and/or their parents completed the INICO-FEAPS scale. Concordance between self-reports and proxy-reports were examined, and factors associated with QoL were explored via linear regression models. RESULTS: Compared to proxy-reported QoL scores, self-reported QoL scores were significantly but only slightly higher and not in every QoL domain. Independent of respondent type it was found that psychiatric comorbidity, sleeping difficulty, intellectual disability, maladaptive behavior, adaptive functioning, autism symptomatology, main daytime activity and residence were associated with QoL. CONCLUSION: Proxy-reported QoL is different from self-reported QoL and should be considered as an alternative source of information. QoL might be enhanced when factors associated with QoL are improved. However, large variations in QoL were found for most factors, suggesting the need to involve the individuals with ASD and/or their families when improving their QoL.

An international clinical study of ability and disability in ADHD using the WHO-ICF framework.

This is the fourth and final study designed to develop International Classification of Functioning, Disability and Health (ICF, and children and youth version, ICF-CY) core sets for attention-deficit hyperactivity disorder (ADHD). To investigate aspects of functioning and environment of individuals with ADHD as documented by the ICF-CY in clinical practice settings. An international cross-sectional multi-centre study was applied, involving nine units from eight countries: Denmark, Germany, India, Italy, Portugal, Saudi Arabia, Sweden and Taiwan. Clinicians and clinical researchers rated the functioning level of 112 children, adolescents and adults with ADHD using the extended ICF-CY checklist version 2.1a. The ratings were based on a variety of information sources, such as medical records, medical history, clinical observations, clinical questionnaires, psychometric tests and structured interviews with participants and family members. In total, 113 ICF-CY categories were identified, of which 50 were related to the activities and participation, 33 to environmental factors and 30 to body functions. The clinical study also yielded strengths related to ADHD, which included temperament and personality functions and recreation and leisure. The study findings endorse the complex nature of ADHD, as evidenced by the many functional and contextual domains impacted in ADHD. ICF-CY based tools can serve as foundation for capturing various functional profiles and environmental facilitators and barriers. The international nature of the ICF-CY makes it possible to develop user-friendly tools that can be applied globally and in multiple settings, ranging from clinical services and policy-making to education and research.

An International Clinical Study of Ability and Disability in Autism Spectrum Disorder Using the WHO-ICF Framework.

This is the fourth international preparatory study designed to develop International Classification of Functioning, Disability and Health (ICF, and Children and Youth version, ICF-CY) Core Sets for Autism Spectrum Disorder (ASD). Examine functioning of individuals diagnosed with ASD as documented by the ICF-CY in a variety of clinical settings. A cross-sectional study was conducted, involving 11 units from 10 countries. Clinical investigators assessed functioning of 122 individuals with ASD using the ICF-CY checklist. In total, 139 ICF-CY categories were identified: 64 activities and participation, 40 body functions and 35 environmental factors. The study results reinforce the heterogeneity of ASD, as evidenced by the many functional and contextual domains impacting on ASD from a clinical perspective.

Psychometric properties of the INICO-FEAPS scale in a Danish sample with autism spectrum disorders.

BACKGROUND: There is a need to evaluate subjective perspectives of outcomes, such as quality of life (QoL), in individuals with autism spectrum disorders (ASD), but to date, there is no specific instrument available to assess this population. While the INICO-FEAPS scale is customized for studying QoL in adolescents and adults with intellectual and/or developmental disabilities, this scale has not been previously evaluated in an ASD population. AIMS: To examine the usability of the INICO-FEAPS scale in a Danish population of adolescents and adults with ASD. METHODS: In a nationwide survey, 875 adolescents and adults with ASD and 1573 parents completed the INICO-FEAPS scale. Internal consistency was evaluated through several indices. Confirmatory factor analysis (CFA) was conducted to investigate the fit of the model with eight correlated first-order factors, and convergent validity was explored comparing the results of different QoL measures through correlation analysis. RESULTS: Internal consistency was adequate for the indices applied, and the CFA model tested indicated an acceptable fit to the data. Generally, comparisons of results of different QoL measures resulted in moderate to high correlations. CONCLUSION: Overall, it was concluded that due to the psychometric properties found, the INICO-FEAPS scale is applicable for use in ASD populations.
