TL;DR: A semantically equivalent translation has been developed with cultural adaptation of OAKHQoL and it is quite reliable and a valid measure of the effect of osteoarthritis on the quality of life on Moroccan patients.
Abstract: The aim of this study was to adapt the knee and hip osteoarthritis quality of life questionnaire (OAKHQoL) into Moroccan Arabic and to determine its psychometric properties. After translation, back-translation and pretesting, the translated version was submitted to an expert committee. The psychometric properties were tested on patients with hip or knee osteoarthritis. Internal consistency was tested using Cronbach’s alpha coefficient (α), and the test–retest reliability using intraclass correlation coefficients (ICC). Construct validity was assessed by examining item-convergent and divergent validity and by comparing the average scores between age groups and walk perimeter groups. The study was conducted on 131 patients (115 with osteoarthritis of the knee and 16 with osteoarthritis of the hip). The “physical activities” (α = 0.93), “mental health” (α = 0.84) and “pain” (α = 0.88) dimensions of the Arabic version were internally reliable. The ICC were adequate to good; 0.83 for “physical activities”, 0.65 for “mental health” and 0.70 for “pain” dimensions. The instrument demonstrated good construct validity; all items exceeded the 0.4 criterion for convergent validity, except items 13 and 41 and most of the correlations between items and their own scale were significantly higher than their correlations with other scales. A semantically equivalent translation has been developed with cultural adaptation of OAKHQoL. It is quite reliable and a valid measure of the effect of osteoarthritis on the quality of life on Moroccan patients.

TL;DR: There are large projected increases in both the prevalence and numbers of people with arthritis and arthritis related disability that, at least in the next 20 years, will be split between the older half of the working population and those aged 65 and older.
Abstract: Objective. To develop Canadian projections for the prevalence and numbers of people with arthritis and arthritis disability, overall and in major age groups. Methods. Age and sex specific data from the 1991 General Social Survey and the 1994 National Population Health Survey on the prevalence of arthritis and arthritis disability were applied to population projections for Canada for every 5 years between 1991 and 2031. Results. Between 1991 and 2031 we project that the prevalence of arthritis diagnosed by a health professional as a longterm condition in Canada will increase from 10.7 to 15.7%, an increase of 46.7%, and the number of people with arthritis will increase from 2.9 to 6.5 million, an increase of 124%. Comparable changes in prevalence and numbers of people with self-reported arthritis are 17.1% (4.7 million) to 23.6% (9.7 million). Most of the increase will be in the population aged 45+, and not until after 2020 will the comparative increase in the 65+ age group be greater than that for the 45-64 age group. Disability attributed to arthritis in the population aged 15+ is projected to increase from a prevalence of 2.3% (595,000) in 1991 to 3.3% (1.13 million) in 2031. Conclusion. There are large projected increases in both the prevalence and numbers of people with arthritis and arthritis related disability that, at least in the next 20 years, will be split between the older half of the working population and those aged 65 and older.

TL;DR: The AIMS2-SF is a shorter version of the AIMs2 (i.e., available in 2-page format) and has psychometric properties similar to those of the former questionnaire, preserving content validity as the priority criterion.
Abstract: Objective. To develop a short form of the Arthritis Impact Measurement Scales 2 (AIMS2) questionnaire, preserving content validity as the priority criterion.
Methods. A 2-step reduction procedure was used: 1) Delphi technique, with 1 panel of patients and 1 panel of experts each selecting 1 set of items independently; and 2) nominal group technique, where members of both panels reached consensus on the final selection of items, using information derived from item analysis. Psychometric properties of the AIMS2-Short Form (AIMS2-SF) and AIMS2 were compared using data from a cohort of 127 rheumatoid arthritis patients who completed the AIMS2 twice prior to the initiation of methotrexate (MTX) treatment and 3 months post-initiation of MTX treatment.
Results. The 2 panels reached consensus on a 26-item AIMS2-SF (54.4% reduction from the AIMS2). Factor analysis showed preservation of the 5-component structure. Convergent validity (Physical and Symptom components with clinical variables: r = 0.24-0.59), test-retest reproducibility (intraclass correlation coefficient >0.7), and sensitivity to change at 3 months (standardized response mean 0.36-0.8, except Social Interaction component [0.08]) were very close to the values for the original AIMS2.
Conclusion. The AIMS2-SF is a shorter version of the AIMS2 (i.e., available in 2-page format) and has psychometric properties similar to those of the AIMS2.

TL;DR: Health interventions in OA, primary dedicated to pain and physical disability, could be supplemented with social support component to enhance health outcomes.
Abstract: Objective: To document the association between social support and health-related quality of life (HRQoL) in hip and knee osteoarthritis (OA). Methods: A prospective survey including the SF-36 and the Social Support questionnaire (SSQ) was administered to 108 hip and knee OA patients attending an outpatient physical rehabilitation and rheumatology clinic. Multiple regression analysis were performed to study the relation between social support and each dimension of the SF-36, controlling for age, sex, body mass index, number of comorbid conditions, socioeconomic status, site of survey completion and severity of OA which was gauged with the pain dimension of the WOMAC, an OA-specific health status instrument. Results: Greater social companionship transactions were associated with higher physical functioning (standardized regression coefficients: β = 0.26, p < 0.01), general health (β = 0.32, p < 0.001), mental health (β = 0.25, p < 0.01), social functioning (β = 0.20, p < 0.05) and vitality (β = 0.25, p < 0.05). Satisfaction with problem-oriented emotional support was related to better physical functioning (β = 0.22, p < 0.01), mental health (β = 0.38, p < 0.001), role-emotional (B = 0.23, p < 0.01), social functioning (β = 0.19, p < 0.05) and vitality (β = 0.26, p < 0.01). Conclusion: Social support components significantly account for HRQoL. Health interventions in OA, primary dedicated to pain and physical disability, could be supplemented with social support component to enhance health outcomes.

TL;DR: The data suggest that the psychosocial impact of OA may have been underestimated and highlight the importance of going beyond disability in assessing the impact ofOA.
