Measuring disability in multiple sclerosis
Disability in MS can be comprehensively measured at interval level by the WHODAS 2.0, and validly monitored over time. Routine use of this self-reported measure in clinical and research practice would give valuable information on the trajectories of disability of individuals and groups
The WHOQOL-BREF
The validation of multiple conceptual frameworks validates the WHOQOL-BREF as a powerful and flexible end-point for use in clinical trials and in testing conceptual models of factors influencing QoL in MS
Measuring Work-Related Functioning Using the Work Rehabilitation Questionnaire (Worq)
The assessment of work-related functioning is a key process in vocational rehabilitation to identify specific domains of disability that can be considered within return to work strategies. The Work Rehabilitation Questionnaire (WORQ) was developed to evaluate work-related functioning based on the International Classification of Functioning, Disability, and Health (ICF) framework and is available in different languages. The aim of this study was t…

Assessing the predictability of self-harm in a high-risk adult prisoner population
BACKGROUND: Prisoners are at increased risk of self-harm and when either intent is expressed, or an act of self-harm carried out, prisoners in the UK are subject to self-harm/suicide monitoring (referred to as "open ACCT" monitoring). However, there is a paucity of validated instruments to identify risk of self-harm in prisoner populations. In response to the need to support prison staff to determine who is at increased risk of self-harm or repea…
The Warwick-Edinburgh Mental Well-being Scale (WEMWBS)
Background The outcomes framework for the new public health and mental health strategies in England (Healthy Lives Healthy People and No Health without Mental Health) both propose monitoring positive mental health. The Office of National Statistics is currently consulting on approaches to the measurement of wellbeing. Public mental health projects and interventions at local level require measurement of mental wellbeing The Warwick-Edinburgh Menta…
Internal construct validity of the Warwick-Edinburgh Mental Well-being Scale (WEMWBS)
BACKGROUND: The Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) was developed to meet demand for instruments to measure mental well-being. It comprises 14 positively phrased Likert-style items and fulfils classic criteria for scale development. We report here the internal construct validity of WEMWBS from the perspective of the Rasch measurement model. METHODS: The model was applied to data collected from 779 respondents in Wave 12 (Autumn 200…
An introduction to the Rasch measurement model
Objectives To demonstrate the use of Rasch analysis by assessing the appropriateness of utilizing the Hospital Anxiety and Depression Scale (HADS) total score (HADS‐14) as a measure of psychological distress. Design Cross‐sectional, using Rasch analysis. Methods The HADS was administered to 296 patients attending an out‐patient musculoskeletal rehabilitation program. Rasch analysis was conducted using RUMM2020 software to assess the overall fit o…
The Rasch measurement model in rheumatology
Admission to hospital following head injury in England
Head injury incidence in England varies by a factor of 4.6 across HA's and PCT's. Planning head injury related services at the local level thus needs to be based on local incidence figures rather than regional or national estimates. Socio-economic factors are shown to be associated with admission, including travel to work patterns and lifestyle indicators, which suggests that incidence is amenable to policy initiatives at the macro level as well …
Assessing and Adjusting for Cross-Cultural Validity of Impairment and Activity Limitation Scales Through Differential Item Functioning Within the Framework of the Rasch Model
INTRODUCTION: In Europe it is common for outcome measures to be translated for use in other languages. This adaptation may be complicated by culturally specific approaches to certain tasks; for example, bathing. In this context the issue of cross-cultural validity becomes paramount. OBJECTIVE: To facilitate the pooling of data in international studies, a project set out to evaluate the cross-cultural validity of impairment and activity limitation…
Disability in young adults following major trauma
The study has revealed significant disability amongst a cohort of young people 5 years post severe injury. Whilst many of these young people were coping well with the consequences of their injuries, others reported continuing problems with the activities of daily life. The factors underpinning the young people's differing experiences and social outcome should be explored
Prevalence of low back pain in the community
STUDY OBJECTIVE: To assist a purchasing district in the planning of services for low back pain by assessing the prevalence of symptoms and the current involvement of primary, secondary, and complementary care in the treatment of low back pain. In the light of these findings, to assess further the potential impact of a new system of open access to physical therapy, as recommended by the British Clinical Standards Advisory Group (CSAG). DESIGN: A t…
Symptomatology of children in contact with sea water contaminated with sewage
STUDY OBJECTIVE--The aim was to determine whether or not there was a measurable risk of ill health associated with contact with sea water for children between the ages of 6 and 11 years old. DESIGN AND SETTING--This was a prospective survey carried out on Blackpool beach. Parents of children between the ages of 6 and 11 years were interviewed over a seven week period during July, August, and September, 1990. Respondents were followed up 10-14 d a…
A confidence interval approach to investigating non-response bias and monitoring response to postal questionnaires
STUDY OBJECTIVE--The aim was to develop an alternative method of investigating non-response bias in postal surveys, including a method of calculating a final full (100%) coverage confidence interval which avoids the wide intervals of existing approaches. DESIGN AND SETTING--As part of a two stage survey of disablement in the community, a first phase postal questionnaire was sent to 25,168 households in Calderdale, West Yorkshire, England. Confide…
Investigating the proxy effect and the saliency principle in household based postal questionnaires
STUDY OBJECTIVE--The aim was to investigate two possible sources of bias inherent in using a household based postal questionnaire, the "proxy effect", inaccurate reporting about characteristics of others, and the "saliency principle", reporting of only the most salient features. This is of importance in surveys concerned with screening the population to identify individuals with certain characteristics, and so possibly relying on one member of th…
Investigating non-response bias in a survey of disablement in the community
STUDY OBJECTIVE--The aim was to investigate the pattern of age specific non-response bias in a two phase survey of disablement in the community. It seeks to examine patterns of response in different age groups to a household based postal questionnaire, and the implication of such trends for the estimation of prevalence of reported dependence. It also looks at the effect that the readiness to respond during the first phase postal questionnaire had…
