“…Both the Standard Nordic Questionnaire and NFAS instruments have been shown to have acceptable validity and reliability. 13,16,17 A limitation of the study is the modest response rate (54%). Nonresponder bias might cause both underestimation (through a "healthy volunteer" effect) and overestimation (through higher participation among persons with musculoskeletal pain) of the prevalence of neck pain.…”

“…These domains have showed high validity in sick-listed persons and in the general population. 15,16 Statistics Data were analyzed using SPSS for Windows (version 14.0) software. Descriptive statistics in the form of frequencies, means, and percentages (with 95% confidence intervals) were applied to describe the neck pain prevalence and distribution of pain patterns, and functioning in people with different patterns of neck pain.…”

BackgroundWork disability is a major problem for both the worker and society. To explore the work opportunities in regular jobs of persons low in functional abilities, we tried to identify occupations low in task demands. Because of the variety of functional abilities and of the corresponding work demands, the disabled persons need to be classified by type of disability in a limited number of subgroups. Within each subgroup, occupations judged suitable for the most seriously disabled will be selected as having a very low level of the corresponding task demands. These occupations can be applied as reference occupations to assess the presence or absence of work capacity of sick-listed employees in regular jobs, and as job opportunities for people with a specific type of functional disability.MethodsRegistered data from 50,931 disability assessments within the Dutch social security system were used in a second order factor analysis to identify types of disabilities in claimants for a disability pension. Threshold values were chosen to classify claimants according to the severity of the disability. In the disability assessment procedure, a labour expert needs to select jobs with task demands not exceeding the functional abilities of the claimant. For each type of disability, the accessible jobs for the subgroup of the most severely disabled claimants were identified as lowest in the corresponding demand.ResultsThe factor analysis resulted in four types of disabilities: general physical ability; autonomy; psychological ability; and manual skills. For each of these types of disablement, a set of four to six occupations low in task demands were selected for the subgroup of most severely disabled claimants. Because of an overlap of the sets of occupations, 13 occupations were selected in total. The percentage of claimants with at least one of the occupations of the corresponding set (the coverage), ranged from 84% to 93%. An alternative selection of six occupations for all subgroups with even less overlap had a coverage ranging from 84% to 89% per subgroup.ConclusionThis study resulted in two proposals for a set of reference occupations. Further research will be needed to compare the results of the new method of disability assessment to the results of the method presently used in practice.

“…Some of these instruments measure sections of the ICF classification structure, such as A&P: examples of this are the IMPACT-S, the screener part of the ICF Measure of Participation and Activities questionnaire [62], the Norwegian Function Assessment Scale (NFAS) [63]. Few instruments have been developed that specifically focus on a disease: to our knowledge, the Functional Assessment in Migraine (FAIM) questionnaire [64] and the Italian Society of Obesity test for obesity-related disabilities (TSD-OC) [65] are the only developed ICF-based disease specific disability assessment tools.…”

Functional ability in a population: normative survey data and reliability for the ICF based Norwegian Function Assessment Scale

Abstract: Background: The increasing focus on functional ability assessments in relation to sickness absence necessitates the measurement of population functional levels. This study assessed the reliability of the Norwegian Function Assessment Scale (NFAS) and presents normative population data.
