Previous research has found a two-factor model of habit and routine in dail
y living to be related to mental health and the occurrence of daily events
in the lives of middle-aged and older adults. The study reported in this ar
ticle extended research on the variable, routinization, to a sample of wome
n with fibromyalgia syndrome, a chronic, debilitating disorder characterize
d by widespread pain and fatigue. The two factors found previously, Having
Order and Routine in Life, and Disliking Disruption were investigated furth
er. The Having Order variable was significantly related to mental health wh
en level of physical functioning was included in prediction equations, and
active coping efforts were effective for the high-order group in improving
mental health. The Disliking Disruption factor was not significantly influe
ntial. Results are discussed in terms of the therapeutic implications for i
mproving the mental health and coping efforts of people with adjustment-thr
eatening illnesses.
