OBJECTIVE: Subjective cognitive dysfunction (SCD) affects 55-75% of individuals with fibromyalgia (FM), but those reporting cognitive difficulties often lack corresponding objective deficits. Symptoms of depression and anxiety are prevalent in FM and may account for part of this discrepancy. This study was undertaken to investigate whether momentary (within-day, across 7 days) changes in mood moderate the relationship between within-the-moment SCD and mental processing speed performance.
METHODS: A total of 50 individuals with FM (mean age 44.8 years, mean education 15.7 years, 88% female, 86% White) completed momentary assessments of subjective cognitive functioning, depressive and anxious symptoms, and a test of processing speed. Assessments were completed 5 times per day for 8 consecutive days on a study-specific smartphone application.
RESULTS: Momentary ratings of SCD were positively associated with mean reaction time (P < 0.001) and variability of processing speed (P = 0.02). Depressive symptoms moderated the relationship between SCD and processing speed, with lower correspondence when depressive symptoms were higher (P = 0.03). A similar moderating effect was demonstrated for both depression (P = 0.02) and anxiety (P = 0.03) on the association between SCD and variability in processing speed performance.
CONCLUSION: Individuals with FM may have more accurate self-perception of momentary changes in mental processing speed during periods of less pronounced mood symptoms based on their corresponding objective processing speed performance. However, during moments of heightened depression and anxiety, we found increasingly less correspondence between SCD and objective performance, suggesting that psychological symptoms may play an important role in self-perception of cognitive dysfunction in FM as it relates to mental processing speed.
