RESUMEN
OBJECTIVE: To determine which self-report instruments best explain hand functioning measured by a generic comprehensive hand function test. METHODS: Six questionnaires currently used in hand osteoarthritis (OA), namely, the Arthritis Impact Measurement Scales 2 Short Form (AIMS2-SF), the Australian/Canadian Osteoarthritis Hand Index (AUSCAN), the Cochin scale, the Functional Index of Hand OA (FIHOA), the Health Assessment Questionnaire (HAQ), and the Score for Assessment and Quantification of Chronic Rheumatoid Affections of the Hands (SACRAH), were administered once in 100 patients with hand OA together with the Jebsen-Taylor Hand Function Test (JTHFT). In addition, 3 other hand function tests with short administration time were used: the Moberg Picking-Up Test (MPUT), the Button Test (BT), and grip strength. The Short Form 36 was used to describe health status. The relationship between the instruments and the JTHFT was determined by correlation analyses. RESULTS: AIMS2-SF total scores had the highest raw correlation coefficient to the JTHFT, followed by AIMS2-SF upper body limitation subscale, SACRAH stiffness subscale, and SACRAH total score. If controlled for age, the HAQ had the highest correlation coefficient. Of the 3 short hand function tests, the MPUT showed the highest raw correlation coefficient to the JTHFT; if controlled for age, the BT had the highest correlation coefficient. CONCLUSION: To comprehensively assess hand functioning in patients with hand OA, we recommend using both a self-report instrument used more generally in various arthritides and a self-report instrument specifically developed for hand OA. If a short test is preferred, we recommend using the MPUT or BT.

OBJECTIVE: To explore the array of concepts important to patients with chronic systemic lupus erythematosus (SLE) and to compare these with instruments assessing disease activity, damage, and health status. METHODS: We conducted a qualitative focus-group study of patients with SLE concerning their problems in daily functioning. The group sessions were tape recorded, transcribed, and divided into meaning units. The concepts contained in these meaning units were extracted and linked to the International Classification of Functioning, Disability and Health (ICF). We then compared the concepts from the focus groups with those concepts covered by SLE activity scores, the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), and the Short Form 36 Health Survey (SF-36). RESULTS: A total of 92 concepts emerged from 5 focus groups; of these, 28 related to body functions and structures, 24 to activities and participation, and 25 to environmental factors. Two concepts were linked to the health condition itself and 6 to personal factors. Seven were not covered by the ICF. Of the 28 concepts regarding body functions and structures, 24 (86%) were covered by the combination of activity scores and the SDI. The SF-36 also addressed 3 of these concepts and contained 9 (38%) of 24 concepts in activities and participation. CONCLUSION: Although the combination of SLE activity scores, SDI, and SF-36, as suggested for SLE studies, well covers body functions and structures and includes a significant portion of problems regarding activities and participation, neither environmental nor personal factors are covered at all.

OBJECTIVE: To explore whether the concepts important to patients with psoriatic arthritis (PsA) are covered by self-report instruments assessing functioning. METHODS: We conducted a qualitative focus group study with PsA patients about their problems in daily functioning. Focus groups were tape recorded and transcribed verbatim. The transcribed texts were divided into meaning units, and concepts contained in these meaning units were extracted. Self-report instruments assessing functioning in PsA were identified in a structured literature search. Using the International Classification of Functioning, Disability and Health (ICF) as a common frame of reference, we determined whether each concept identified in the focus groups was covered by each of the instruments. RESULTS: Thirty-one patients participated in 6 focus groups. The following 9 instruments were included in the present analysis: Arthritis Impact Measurement Scale Short Form; Bath Ankylosing Spondylitis Disease Activity Index; Disabilities of the Arm, Shoulder, and Hand Questionnaire; Dermatology Quality of Life Index; Dougados Functional Index; Health Assessment Questionnaire (HAQ); HAQ-S (HAQ adapted for spondylarthropathies); PsA-specific Quality of Life Instrument; and Short Form 36 Health Survey. Of the 54 concepts identified in 590 meaning units in the transcribed data, 19 concepts (35%) were not covered by any of the instruments. Of these, 11 concepts that were linked to the ICF component environmental factors were not covered by any of the instruments, whereas all concepts linked to the ICF component activities and participation were covered by at least 1 of the instruments (but no single instrument covered all concepts). CONCLUSION: The impact of environmental factors, attitudes towards individuals with health problems, and loss of leisure time may represent important aspects addressing participation that are currently not covered in the instruments assessing functioning in PsA.
