Background Previous studies showed that fatigue in RA is related to pain and disability, and to several psychosocial factors including coping and cognitions. Physical activity patterns, especially a pervasively passive pattern,are related to RA fatigue. Psychosocial factors and specific coping styles may be associated with activity patterns in patients with RA.

Objectives The objective of this study was to investigate whether there is an association between self-efficacy with respect to fatigue, coping style, beliefs about fatigue, and activity patterns in RA patients.

Methods Consecutive RA patients of the rheumatology clinic of the Radboud University Nijmegen Medical Centre (N=152) were enrolled for this study. Patients physical activity during 12 consecutive days was measured with the actometer. A general physical activity score (DOM) reflected the average physical activity over the total 12-day time period and was expressed in the average number of accelerations per 5-min period. The individuals’ activity patterns were based on 12 individual daily physical activity scores. Patients with at least 90% of the daily activity scores below the DOM were classified as pervasively passive while the remaining patients were labeled as (pervasively or fluctuating) active. Beliefs regarding the somatic and non-somatic causes of fatigue were assessed using the Causal Attribution List (CAL), consisting of a somatic and non-somatic factor. Self-efficacy concerning fatigue was assessed using the Self-Efficacy Scale 28 (SES28). Coping strategies were assessed using the Modified Fatigue Coping Inventory (MPC-I-F). Catastrophizing of fatigue was assessed with the Fatigue Catastrophizing Scale. The association between these psychosocial factors and active/passive daily activity patterns was analyzed using an independent t-test or Mann-Whitney U test, as appropriate.


Table 1. Comparisons between passive and active RA patients and the association of psychosocial factors

There were no differences found between causal attributions, self-efficacy, several coping styles and the level of daily activity. Passive patients had resting more frequently as coping style.

Conclusions In RA patients, having a pervasively passive or active activity level was unrelated to beliefs, self-efficacy, and coping style. Therefore, activity level and coping style may be independent factors to target in RA.
