Quality of life and psychological well-being in the early stages of multiple sclerosis (MS): Importance of adopting a biopsychosocial model.
L B Strober
PMID 29891186WHAT IT FOUND
In newly diagnosed MS, anxiety and locus of control predicted 40% of quality of life variance, outweighing disease symptoms.
Clinicians should assess coping and perceived control early, not just physical disability.
Key findings
01Anxiety and locus of control were the only significant predictors of quality of life in the final model, accounting for 40% of the variance.
02Individuals with low to average quality of life reported greater fatigue, sleep disturbance, and pain compared to those with high quality of life.
03High quality of life was associated with adaptive coping strategies like planning and acceptance, while low quality of life was linked to behavioral disengagement.

What it does not show
The study is cross-sectional, so it cannot prove that anxiety or locus of control cause poor quality of life. The sample was small (n=69) and restricted to employed individuals, which limits generalizability to unemployed or more disabled patients. Participants self-reported MS diagnosis and quality of life status, introducing potential bias. The authors claim the study was not underpowered due to large effect sizes, but small samples remain vulnerable to unstable estimates.
Declared interests
The author declared no conflicts of interest.
The easy way to misread this
Do not assume that treating physical symptoms like fatigue or pain will automatically improve quality of life. The study found that psychological factors, specifically anxiety and locus of control, were stronger predictors of well-being in early MS than disease severity.
