Abstract

OBJECTIVES:
Physical inactivity and sedentary behaviours are considered as risk factors for global mortality and primary contributors to the obesity epidemic. We assessed the psychometric properties and transcultural adaptation into Spanish of the Sedentary Behaviour Questionnaire in fibromyalgia patients.
METHODS:
The Spanish version of the Sedentary Behaviour Questionnaire (SBQ-S) was translated and cognitively pretested following cross-cultural adaptation guidelines. Test-retest reliability was evaluated in 114 fibromyalgia patients. Fifty-one participants wore a body monitoring device (SWA) for nine consecutive days and filled the SBQ-S twice (separated by a one-week interval). Measures of sedentary time assessed by the SBQ-S and the SWA were compared.
RESULTS:
Overall reliability of the SBQS scores was good. The intraclass correlation coefficients were excellent for the SBQ-S total scores (from 0.83 to 0.86), and varied from moderate to excellent for 10 of the 11 sedentary behaviours (from 0.52 to 0.96). There was no significant association between the SBQ-S and the SWA for the weekday, weekend, and total sedentary time (from r -0.06 to -0.03). Differences between the SBQ-S and the SWA increased as the hours per day of sedentary time increased (beta coefficients varied from -0.713 to -0.330, all p<0.02).
CONCLUSIONS:
The SBQ-S developed in this study presents a good reliability and poor convergent validity when compared with the SWA in the Spanish fibromyalgia patients studied.
