Objective: The objective was to create a linguistically and culturally validated Swedish version of the Valued Life Activities scale. The aim was also to describe its content and concurrent validity and its internal consistency in persons with rheumatoid arthritis. Methods: The Valued Life Activities scale was translated to Swedish and culturally adapted. In order to describe the content validity, both the Swedish and original Valued Life Activities scale were linked to the International Classification of Functioning, Disability and Health. The concurrent validity and internal consistency were evaluated in 737 patients with rheumatoid arthritis. To establish concurrent validity, the scale was correlated to disease activity, activity limitations, and life satisfaction. Internal consistency was assessed with Cronbach’s alpha. Results: The equivalence of meaning between the Swedish and the original Valued Life Activities scale was ensured by harmonization review. Content validity was high when linked to the International Classification of Functioning, Disability and Health. Concurrent validity showed a strong correlation with the activity limitations (r = 0.87), moderate with life satisfaction (r = –0.61), and weak with disease activity (r = 0.38). Internal consistency was excellent (Cronbach’s alpha = 0.97). Conclusions: The Swedish Valued Life Activities scale has been tested in a large and well-characterized sample and found to be a linguistically valid and culturally adapted self-reported measure of participation. Content validity of the Valued Life Activities scale was excellent, concurrent validity strong, and the internal consistency excellent. Since both individual preferences and International Classification of Functioning, Disability and Health concepts of disability are taken into account, the Swedish Valued Life Activities scale appears to be a promising new scale addressing important aspects of participation.

Content validity describes the extent to which a measure represents, and is relevant to, the construct it aims to assess. The International Classification of Functioning, Disability and Health and derived Core/Code Sets (Sets) for autism, attention deficit-hyperactivity disorder, cerebral palsy and early developmental delay and disability are adequate to establish the content validity of measures aiming to assess functioning in young children with neurodevelopmental conditions (NDCs). This article aimed to assess the content validity of comprehensive assessments of functioning for young children with NDCs against these standards. Twenty-two common measures of functioning were evaluated for content validity against the International Classification of Functioning, Disability and Health at a domain level, with 10 measures analysed at the item-level and compared to the Sets relevant to young children with NDCs. Measures covered between 21% and 57% of the combined Set codes and 19% to 63% of codes from specific Sets. Much of this variation was between measures, with some variation due to differences between individual Sets. The percentages reflect that measures heavily focus on activities and participation areas, with environmental factors rarely assessed. These findings are useful for clinicians, policymakers, and researchers in identifying the most appropriate measures for assessing functioning in young children with neurodevelopmental conditions. Lay abstract Young children who have developmental delay, autism, or other neurodevelopmental conditions can have difficulties doing things in different areas of their life. What they can and cannot do is called their level of functioning. There are lots of assessment measures that aim to assess functioning. But, we are not sure if these measures assess all the things we need to know about these children’s functioning. Other research has identified lists of items (codes) that need to be assessed to understand functioning for young children with different neurodevelopmental conditions fully. These lists include body functions (the things a child’s body or brain can do), activities and participation (the activities and tasks a child does) and environmental factors (parts of the environment that can influence functioning). In this study, we looked at the items from these lists assessed by different functioning measures to see how they compared to what should be assessed. The measures that we looked at covered 21%–57% of all the codes and 19%–63% of the codes for lists specific to different conditions. Most of the measures focused on activity and participation codes, and they rarely assessed environmental factors. Knowing which codes and how much of the lists the measures assess can help researchers, clinicians and policymakers to choose measures that are more appropriate for young children with neurodevelopmental conditions.

Objective.To determine the categories of the International Classification of Functioning, Disability and Health (ICF) checklist and core sets of rheumatoid arthritis and ankylosing spondylitis frequently occurring in people with psoriatic arthritis (PsA) and to compare the number of such categories with scores on self-report measures of participation restrictions and activity limitations.Methods.Data were collected from 94 patients with PsA attending rheumatology clinics in 6 centers. For each ICF category affected by PsA in at least 30% of patients, the percentage of such patients was determined for Body Structures, Body Functions, Activities and Participation, and Environmental Factors. A count of all affected categories by ICF chapter was compared to patient self-report scores on a number of functional and health status instruments using Spearman’s correlation.Results.There were 25 categories in the Body Functions section, 6 categories in the Body Structures section, and 51 categories in the Activities and Participation section that were relevant in at least 30% of participants. Thirteen Environmental Factors were facilitating and 1 Environmental Factor (climate) was a barrier in at least 30% of participants. The number of involved Activities and Participation categories by chapter did not correlate in predictable ways with self-report measures of participation restrictions and activity limitations.Conclusion.PsA is associated with a wide range of impairments, limitations, and restrictions across the ICF categories. People with PsA find environmental factors to be helpful more often than to be barriers. The unexpected pattern of correlation between ICF chapters and self-report measures suggests the need for a better way of quantitatively representing the ICF concepts.
