As outcome measures, we used a questionnaire, time taken, visual analog scales of perceived exertion and back strain, folded width, videotape and Ovako Working Posture Analysis System (OWAS) back scores (1 4).
They thanked the teachers for their participation and administered the first questionnaire (time for processing: 30 minutes), which included demographic questions and a general ability test (not subject of this article).
Since FDM integrates the fuzzy theory with the FDM, it provides the user with the advantage of Delphi method and reduction of the questionnaire time and cost (Hsu 2010; Yu-Feng 2008).
From the recent PA questionnaire, time (hours per week) spent in different activities was computed.
Thirty-three paresponsets (rateonse RRte (RR) = 72 %) completed the first questionnaire (Time 1).
At the final session, after 4 weeks, participants complete a second questionnaire (time 2) and are handed a packet of two follow-up questionnaires (time 3 and time 4) with stamped envelopes addressed to the principal investigator.
At each questionnaire time point, participants will be asked their current goals and their goals in 12 weeks.
At 1 day after this baseline scan, they received a third questionnaire (Time 2, T2) and were asked to complete this questionnaire within 1 week.
This hypothesis is supported by the subgroup comparison of the questionnaire time point, which showed that the time point had no significant influence.
