Abstract (2584 Views)
Aims: This study aimed to assess the effectiveness of an intervention on fiber consumption, self-efficacy, perceived benefit, and barriers among the elderly using the Trans-theoretical Model (TTM).
Materials & Methods: This quasi-experimental study was developed among constipated elderly people aged ≥60 in Karaj, Iran, between 2019 and 2021. Constipated participants were randomly assigned to the intervention (n=66) or the control (n=64) groups. Before and after four educational sessions, demographic information, participants’ stages of change for diet, self-efficacy, decisional balance, and daily amount of fiber consumption were evaluated. An analysis was performed to assess any differences in the stages of change (posttest vs. baseline).
Findings: The perceived barriers and self-efficacy were statistically significant after intervention (p<0.001) in the intervention group compared to the control group (p>0.001). In both groups, perceived benefits changed statistically significantly (p<0.001). Pearson correlation also showed a significant correlation between stages of change and benefits, barriers, self-efficacy, and fiber consumption. The analysis of variance adjusting for covariates also indicated significant differences between intervention and control groups.
Conclusion: The TTM is a useful model that can be applied to dietary behavior change, specifically fruit and vegetable consumption among elderly populations.
