Although benefits of regular physical activity (PA) in people with multiple sclerosis (pwMS) are well known, evidence suggests that pwMS have inadequate PA levels. For this reason, it is extremely important to measure PA in clinical practice. Although there are many questionnaires and technological approaches to assess PA, these methods are not always practical in a busy practice. The aim was to determine the psychometric properties of a simple single question to assess PA in pwMS.
The data of 355 pwMS were investigated in this retrospective study. Physical disability levels were assessed using the Expanded Disability Status Scale (EDSS). Regular exercise habits were questioned with a single question “Do you exercise regularly?” with response options "Yes" and "No". Additionally, the Godin Leisure-Time Exercise Questionnaire (GLTEQ) was used to assess PA levels. Participants with a GLTEQ score of 24 and above were classified as active, while those below 24 were classified as insufficiently active. Beck Depression Inventory (BDI), Modified Fatigue Impact Scale (MFIS), Timed Up and Go (TUG), Timed 25-Foot Walk (T25FW), and Nine-Hole Peg Test (9HPT) were used in addition to the GLTEQ to assess validity. The specificity and sensitivity of the single question method according to the GLTEQ were also calculated.
There was no significant difference in age, gender, EDSS score and disease duration among the participants who answered "Yes" (28.7%) and "No" (71.3%) in the single question (p>0.05). BDI (p=0.002), MFIS (p< 0.001), TUG (p=0.011), and T25FW (p=0.04) scores of "Yes" responders were significantly better than the "No" responders. There was no significant difference between the scores of dominant and non-dominant 9HPT between the two groups (p=0.862 and 0.597, respectively). According to GLTEQ score, 75.8% of participants had insufficient PA level. The specificity and sensitivity of the single question was calculated as 83.3% (95% Confidence Interval (CI): 78.3-87.5%) and 66.3% (95% CI: 55.3-76.1%), respectively.
The results showed that the single question has adequate concurrent, convergent and discriminant validity to assess PA levels in pwMS. It was also found that the single question has adequate specificity to detect pwMS with insufficient PA level. A single question such as "Do you exercise regularly?" is thought to be a psychometrically adequate measure in intensive clinical practice for referring pwMS to more advanced tests and interventions for PA.
