Evaluation and cultural adaptation of a German version of the AIMS2-SF questionnaire (German AIMS2-SF)

Abstract

The German AIMS2-SF is a reliable and valid instrument to assess the quality of life in primary care patients suffering from OA. When addressing the different impacts of OA, the physical scale should be divided into an upper body scale and a lower body scale. The floor and ceiling effects revealed are in accordance with the disease characteristics of the study sample and do not limit the significance of the questionnaire.

Cultural adaptation and validation of the Persian version of the Arthritis Impact Measurement Scales 2-Short Form in patients with osteoarthritis of the knee

“…The test-retest reliability of the AIMS2-SF was good to excellent, with ICCs ranging from 0.72 to 0.83. The ICC for most components reported in this study for the Persian AIMS2-SF was similar to those reported in previous studies [12,13,15,16]. OA of the knee is the most prevalent disease among adults in Iran, with reported 7-days period prevalence of symptomatic OA as high as 15.3% [27].…”

“…These values were within the range previously reported for the AIMS2-SF [12,13,15,16]. For the social interaction scale the Cronbach's alpha was 0.71, which is higher than the majority of coefficients previously reported: the range of reported values is 0.32-0.67 [12,13,15,16].…”

“…The factor analysis using the remaining 24 items extracted five factors with eigenvalues greater than 1 that jointly accounted for 66.9% of the total variance. The first factor represented lower body limitation (items 1-5,11,12), the second factor represented upper body limitation (items 6-10), the third factor represented symptom (items 13-15), the fourth factor represented affect (items [16][17][18][19][20] and the fifth factor represented social interaction (items [21][22][23][24]. The results are shown in Table II.…”

“…The numbers of items in the AIMS2-SF was reduced to 26 items to reduce time and to increase acceptance among patients in clinical settings and research. The AIMS2-SF has already been translated into several languages and has shown good internal consistency, test-retest reliability, validity and responsiveness [13][14][15][16]. Most available questionnaires are in English and appropriate international use of these tools depends on adapting them to different languages and cultures while maintaining functional equivalence [17].…”

Patient perspective of hand osteoarthritis in relation to concepts covered by instruments measuring functioning: a qualitative European multicentre study

“…The following most commonly used instruments measuring functioning in patients with hand OA were identified in a structured literature search which has been described elsewhere33 and included in this analysis: the Health Assessment Questionnaire (HAQ),1434 the AUSCAN (AUS),1135 the Cochin (COC) scale,1236 the Functional Index of Hand OA (FIHOA; FIH),1537 the Score for Assessment and Quantification of Chronic Rheumatoid Affections of the Hands (SACRAH; SAC) questionnaire1638 and the Arthritis Impact Measurement 2 Short Form (AIMS2-SF; AIM) questionnaire 1339…”
