Sample Size Power analysis calculation on sample size is based on previous studies on community-based programs conducted in community-dwelling older adults which reported sense of coherence having a medium effect size (d=0.46-0.57). Sample size calculation is therefore calculated based on a medium effect size of 0.5. A minimum sample size of 64 participants in each group is needed to detect a difference between groups at an alpha of 0.05 and power of 0.80. We estimate 20% attrition rate, a total of 154 participants would be needed, with 77 in each group
