Abstract
Background Previous studies showed a lack of long term effeds of interventions aiming to increase physical activity. Next to focusing on motivation, reducing perceived barriers to physical activiW seems promising to increase and maintain activiW eve~. Furthermore, it is not known yet how contents of interventions can influence the accuracy of self-reported physical activiW, while this is a commonly used measurement to retermine intervention effects. Therefore, the aim of this study was to investigate the effect of two various barrier approach interventions for adults on 1) physical activiW leves, and 2) the accuracy of self-reported physical activity. Methodv Accelerometers were used to objectively determine physical activit¥ at the pretest and posttest These results were compared with the results of questionnaires to retermine the accuracy of self-reported activiW. Participants (18-70 years okl) were rancbmly assigned to a taihred individual intervention (N=12) or to a usual care group intervention (N=9). Results For both interventions, a non-significant trend was found for increased activiW eve~ at the posttest. The accuracy of self-reported activit¥ decreased for aU eves after attending an intervention, except for light activities of the individual intervention where a Jarge increase of accuracy was found Conclusions Reducing perceived barriers to physical activit¥ might be helpful in increasing activit¥ levek A change in the accuracy of self-reported activi}1 leves shows the need for interventions to use objective measurements to determine effects on physical activiW.
