Özet

Individualized health promotion activities are needed to bring the disadvantaged groups into healthy lifestyle behaviors. The older adult is both the most inactive and the most affected by physical inactivity  in  the  community.  Primary  care  nurses  can  help 65+  adults  to  gain  exercise  behavior  by using  their  educator  and  guidance  roles.  The  Trans-Theoretical  Model  (TTM)  is  an  individualized counselling model that evaluates the behavior change as a process. TTM with motivational interviews (MI) is used to promote various health behaviors. This randomized-controlled trial will be conducted to investigate the effect of TTM based-MI on promoting exercise behavior in healthy older adults. The population  is  constituted  of  voluntary  seniors  who  meet  the  inclusion  criteria  (n=117)  from  65-74 aged  adults  (N=1630)  who  registered  to  a  family  health  center.  A  power  analysis  was  performed  to sample size estimation with .30 effect size and .80 power. The projected sample size was found 90. The participants  are  divided  into  stratums,  blocking  according  to  the  age,  gender  and  exercise  behavior stages  of  change.  The  seniors  from  the  created  stratums  is  allocated  into  intervention  and  control groups randomly. The data will be gathered via a questionnaire, TTM scales, KATZ Activities of Daily Living Scale (KATZ-ADL) and Physical Activity Scale for Elderly (PASE). Waist circumferences will be  measured  and  average  weekly  step  counts  will  be  calculated  via  a  pedometer.  The  data  will  be collected  via  an  independent  researcher,  blinded to  the  study  groups.  TTM-based  MI  for  gaining exercise behavior program is planned to apply to the intervention group overall six times (face-to-face for four times biweekly and twice via telephone by four weeks). Intervention period is planned as six months.  The  results  obtained  are  expected  to  guide  the  community  health  nurses  in terms  of  gaining exercise behavior of the older adults. This study is registered to clinicaltrials.gov, NCT04128553.
