Availability

The instrument is freely available here: Please click here for the Functional Assessment in Multiple Sclerosis

Classification
Supplemental: Multiple Sclerosis (MS)
Short Description of Instrument
Construct measured: Mobility and quality of life
 
Generic vs. disease specific: Disease specific
 
Means of administration: Self administered
 
Intended respondent: Patient
 
# of items: 59
 
# of subscales and names of sub-scales: 6 – mobility, symptoms, emotional well being/depression, general contentment, thinking/fatigue and family/social well being

Comments/Special Instructions
Scoring: Unscored items are retained for their clinical and empirical value. A Likert-type 5-point scale (ranging from "not at all" to "very much") produces a score between 0 and 4 for each scored question (44 of the 59 items).
 
Background: The FAMS is a patient-completed disease specific questionnaire regarding perceptions of mobility and quality of life in people.
Rationale/Justification
Strengths/ Weaknesses: The FAMS was created on an existing measure—the Functional Assessment of Cancer Therapy: General Questionnairre with additional items generated by experts and interviews with patients.
 
Psychometric Properties: There is good internal consistency reliability for the subscales of the MSQLI, with the lowest alpha being 0.67 (for social functioning on SF-36). Other coefficients range from 0.78 (BWCS) to 0.97 (MSSS). Test- retest reliability on the SF-36 ranges from 0.
 
Administration: Self-completion by the patient
