The results are based on 69 participants who completed the MSQLI questionnaire.
Table 2: MSQLI Scales Used in this Study Name Modified for this study Medical Variables--Subjective A.1 Pain Effects Scale Includes 1 item, "How much bodily (from SF-36) pain have you had during the past 4 weeks?" A.2 Pain Effects Scale (6 Includes 2 items, e.g., "During the items) past 4 weeks, how much did these (Ritvo et al., 1997) symptoms interfere with your ability to walk or move around?" B.
QoL was assessed by three self-report questionnaires: the MS Quality of Life Inventory (MSQLI) , the Fatigue Severity Scale (FSS) , and a single-item measure of general Life Satisfaction (LS) .
The MSQLI is a modular psychometric instrument comprising a well-established general HRQoL measure, the 36-Item Short Form Health Survey (SF-36) from the Medical Outcomes Study (MOS) , and nine symptom-based scales that represent areas of specific concern to people with MS.
The MS QOL Inventory (MSQLI) is a modular MS-specific health-related QOL instrument consisting of a widely used generic measure, the 36-item short form Medical Outcomes Study Health Status Questionnaire that is supplemented by nine symptom-specific measures .
Some of the items in the PDQ correlated very highly with depression, and since other scales in the MSQLI already address mood and affect, these items may not be needed.
The first set of scales administered was from the Multiple Sclerosis Quality of Life Inventory (MSQLI
; Ritvo et al., 1997) and included Health Status Questionnaire (SF-36), Fatigue Impact Scale, Pain Effects Scale, Impact of Visual Impairment Scale, Perceived Deficits Questionnaire, Mental Health Inventory, and the Modified Social Support Survey.
