Abstract
Objectives: To characterize and compare the demographics, symptom profiles, pain coping strategies, and quality of life in three age groups of women with fibromyalgia [FMS].
Methods: Self-report questionnaires, including the Fibromyalgia Impact Questionnaire [FIQ], Beck Depression Inventory, Coping Strategies Questionnaire, and Quality of Life Scale, were filled out by 343 consecutive women who were participating in FMS treatment programs. Patients were divided into three age groups for purposes of data analysis.
Results: The youngest age group had their symptoms for a significantly shorter period of time than the middle age and older age groups. Tender point pain score, the FIQ physical functioning and well-being items, and perceived ability to decrease pain were significantly worse for the youngest age group when compared to the other two groups. The youngest group had significantly higher catastrophizing scores and lower quality of life than the oldest age group. Discriminant function analysis between the youngest and oldest groups revealed that a combination of six variables: length of symptoms, quality of life, tender point pain score, morning tiredness, behavioral activity strategies, and a pain control/rational thinking factor were 84% accurate in classifying these patients into their original groups. When length of symptoms was excluded, the remaining five variables were 79% accurate in classifying the patients.
Conclusions: Young women with FMS perceive the severity of FMS to be higher and respond with more distress than older women with FMS. This finding is largely independent of symptom length.
