The Effect of The Information-Motivation-Behavioral Skills Program on Medication Adherence in Elderly Glaucoma Patients at Udonthani Hospital

Abstract

This pre-experiment research one group pre–posttest design aimed to explore medication adherence, to compare the mean score of medication adherence and satisfaction pre-post Information - Motivation - Behavioral Skills (IMBS) program at eye clinic, Udonthani Hospital. Thirty-two elderly glaucoma patients calculated by program G*Power were assigned into study by purposive sampling. The instruments consist of personal information, knowledge, skills, and satisfaction questionnaires and IMBS program by Fisher’s model and reviewed by 3 experts. The reliability of glaucoma knowledge, skills use of eye drops and satisfaction questionnaire tests by Cronbach’s alpha were 0.75, 0.70 and 0.84 respectively. Collected data from February 1^st 2021 to May 31^st 2021. The data was analyzed by descriptive statistics and inferential statistics using Paired T-test.

The results showed that the sample group 56.3% were female, mean age 63.6 years old. After participating in the program, the mean score of knowledge increased from 11.2 (S.D.=2.2) to 14.3 (S.D.=0.9), with statisticaly significant (p<0.001). The mean score of skills use of eye drop increased from 34.7 (S.D.=3.3) to 37.0 (S.D.=2.9), with statisticaly significant (p<0.001). And the mean score of satisfaction increased from 40.8 (S.D.=4.0) to 41.8 (S.D.=4.2) with no statistically difference (p=0.069).

Conclusion: The Information-Motivation-Behavioral Skills program on medication adherence in elderly glaucoma patients showed that the sample group after participating in the program, the mean score of knowledge and skills were increased with statisticaly significant. The mean score of satisfaction was increased but no statistically difference (p=0.069). Recommend that long term qualitative study, at least 6 months-1 year for more information about belief, perception barrier of behaviors, evaluated for IOP, visual acuity, prognosis by doctor, adherence behavioral and persistency use of eye drops should be considered.
