ABSTRACT

PURPOSE: This study analysed the longitudinal associations of physical fitness and affect with depression, anxiety and life satisfaction at 2- and 5-year follow-up.

METHODS: In 312 adult women with fibromyalgia, physical fitness was measured by performance-based tests and affect, depression, anxiety and life satisfaction were self-reported using the Positive and Negative Affect Schedule (PANAS), Beck Depression Inventory-second edition (BDI-II), State Trait Anxiety Inventory-I (STAI) and Satisfaction with Life Scale (SWLS), respectively. We conducted sequential linear regression analyses adjusted for baseline levels of depression, anxiety, life satisfaction, age, body fat percentage and education.

RESULTS: At the 2-year follow-up, all the associations under study were significant. At the 5-year follow-up, a number of associations remained significant. First, lowering negative affect was independently associated with lower depression, anxiety and higher life satisfaction (β’s from 0.14 to 0.31). Second, favourable changes in positive affect were independently associated with lower anxiety (β = 0.21) and higher life satisfaction (β = 0.28). Third, enhancing physical fitness was related to higher life satisfaction (β = 0.16).

CONCLUSION: Reductions in negative affect were associated with more favourable depression, anxiety and life satisfaction at the 2- and 5-year follow-up. Improvements in positive affect were associated with more favourable anxiety and life satisfaction and enhancements in physical fitness were associated with higher life satisfaction. If corroborated in clinical-experimental research, these findings may guide the development of interventions that are tailored to the levels of physical fitness, affect and the outcome of interest (i.e. depression, anxiety or life satisfaction) in women with fibromyalgia.
