“…Our study found reported adherence to be low compared with a number of studies, 22,23,[41][42][43][44][45][46][47] which may be due to the following: the questionnaire was delivered by interview, which provided a 100% response rate, therefore reducing selection bias. Adherence was measured by asking patients on average how many drops they missed per month, had we narrowed the time period to how many drops they missed in the last month or last week, for example; a higher reported adherence rate may have ensued.…”

“…23 We modified the scale to be appropriate for glaucoma patients and eye drop use with input from four practicing ophthalmologists, 10 glaucoma patients taking glaucoma eye drops, the peer-reviewed literature, and results from our earlier work, 31 in which we asked over 300 glaucoma patients from four practices about their problems and concerns in using their glaucoma medications. [32][33][34][35] The main changes that were made to the medication self-efficacy scale in hypertensive patients scale were that the questions asking about specific side effects to anti-hypertensive medications were modified to reflect specific side effects of glaucoma medications. Also, we added a series of questions focusing on ability to use eye drops correctly.…”

“…Also, we added a series of questions focusing on ability to use eye drops correctly. 31,32 Therefore, we developed a questionnaire with two proposed dimensions (one focusing on overcoming barriers to eye drop use in general and one focusing on the patient's ability to use eye drops correctly). The glaucoma outcome expectations instrument was modelled after an outcome expectations scale from asthma, but we modified the questions to make them appropriate for glaucoma patients.…”

Purpose The purpose of this study was to develop and evaluate the psychometric properties of (a) a glaucoma medication selfefficacy scale and (b) a glaucoma outcome expectations scale.Patients and Methods Two instruments were developed: a glaucoma medication selfefficacy scale and a glaucoma outcome expectations scale. Packets containing (a) the instruments and patient demographic questions and (b) a letter explaining the study were distributed to 225 glaucoma patients from three ophthalmology practices between August and December 2007. The instrument was completed by 191 patients for a response rate of 85%. Principal components factor analysis with a varimax rotation and Cronbach's a reliability were used to analyse the data. To assess discriminant validity, we administered the scales and two self-reported measures of adherence in a separate sample of 43 glaucoma patients who were currently using at least one glaucoma medication.Results Our results yielded a 21-item self-efficacy in overcoming barriers that might interfere with the use of glaucoma medications scale, a 14-item self-efficacy in carrying out specific tasks required to use eye drops correctly scale, and a four-item glaucoma outcome expectations scale. Results of the Cronbach's a reliability indicated that the scales are internally consistent. The selfefficacy scales were both significantly associated with two patient self-reported measures of glaucoma medication adherence, which show discriminant validity.Conclusions Eye care providers and researchers can use these scales to identify patients with low self-efficacy in using their glaucoma medications and patients who do not believe that following their eye care providers' advice can help their vision.

“…Patients' ability to manage glaucoma medications can differ according to their socioeconomic status, health-care experiences, and health beliefs. [10][11][12] Understanding individual patients' needs and providing follow-up support accordingly may prove to be more effective in promoting adherence than a standardised approach.…”

Purpose To evaluate the impact of individualised patient care, as an adjunct to standard care, on adherence to ocular hypotensive therapy. Methods A two-arm, single-masked exploratory randomised controlled trial recruited patients newly prescribed ocular hypotensive therapy. The intervention involved an individual assessment of health-care needs and beliefs and a 1-year follow-up period according to need. The primary outcome was refill adherence, measured by collating prescription and dispensing data for 12 months. Secondary outcomes included self-reported adherence, glaucoma knowledge, beliefs about illness and medicines, quality of care, intraocular pressure (IOP) fluctuation, and changes in clinical management assessed at 12 months. The strength of the intervention was measured following withdrawal by reviewing clinical outcomes for a further 12 months. Results In all, 127 patients were recruited (91% response rate). Intervention-arm patients collected significantly more prescriptions than control-arm patients. Self-report adherence was significantly better in the intervention-arm for patients who forgot drops and those who intentionally missed drops. The intervention group demonstrated significantly more glaucoma knowledge, expressed a significantly stronger belief in the necessity of eye drops and believed that they had more personal control over managing their condition. Control-arm patients had more IOP fluctuation and changes in clinical management. However, this finding only reached significance at 24 months. Conclusion Modelling patient care according to health-care needs and beliefs about illness and medicines can have a significant impact on improving adherence to therapy for this patient group, with the potential benefit of improving clinical outcomes.
