Problem solving (β=0.28) and avoidance (β=0.25) was related to a higher MCS in the first 3 years of diagnosis.
Nourbakhsh et al (2016)98Longitudinal (T1=basal level/T2=3 months after diagnosis/T3=6 months after diagnosis/T4=12 months after diagnosis/T5=18 months after diagnosis/T6=24 months after diagnosis/T6=36 months after diagnosis)Short Form Health Survey 36 (SF-36)N=43
36 years
72%
Baseline severity of fatigue and depression predicts PCS and cognitive function and fatigue MCS in the first 3 years of diagnosis.
MS progression

34.1 years
74%
A second clinic event consistent with CDMS, higher EDSS at the diagnosis and an earlier onset CDMS predicts a decrease in PCS.
Bueno et al (2014)101Cross-sectional (25–30 years after diagnosis)Multiple Sclerosis Quality of Life-54 Instrument (MSQoL-54)N=61
54.9 years
83.6%
Patient changing from benign (EDSS<3) to non-benign (EDSS>3) decreases PCS.
Years of MS duration

40.0 years
74.3%
Low levels of QoL, higher MS duration and higher EDSS level at T1 predicted worse QoL at T2.

41.5 years
71%
Higher EDSS and depression at basal level predicted a decrease of QoL at T1 and T2.

59.8 years
71.6%
Higher pain predicts a decrease in QoL.

49 years
72%
Cognitive impairment, depressive symptoms and EDSS predicted a decrease in QoL at T2.
Group age

50 years
73.7%
The youngest group (35–44) presents worst PCS vs the oldest (55–65).

Risk of neurologic impair­ment, physical disability, depression and the comorbidity of thyroid disease was associated with decrease in PCS. Being widowed and employed was associated with increase in PCS.
