“…At baseline, information was collected regarding patient demographics, health history, health habits, prior osteoporosis diagnosis or treatment, osteoporosis knowledge using the Osteoporosis and You scale (scale items are provided in Table 1) 23 , patient activation, osteoporosis health beliefs and osteoporosis self-efficacy. We also collected results from their index DXA including T-scores, femoral neck BMD, and the interpreting physician’s impression (normal, osteopenia or osteoporosis).…”

Objectives As many as half of the patients recommended for osteoporosis pharmacotherapy do not take their medications. We examined patient characteristics associated with non-adherence to recommended pharmacotherapy, as well as their reasons for non-adherence in order to identify intervention targets. Methods Data come from the Patient Activation after DXA Result Notification (PAADRN) study, a randomized controlled trial of 7,749 patients 50 years old or older presenting for DXA at three health centers in the United States. We focused on the 790 patients who reported receiving a recommendation for new pharmacotherapy at baseline. Using Pearson Chi-squared tests for categorical variables, two sample t-tests for continuous variables, and multivariable multinomial logistic regression, we compared those who reported starting the recommended medication (adherers) to temporary non-adherers and non-adherers on demographics, health habits, DXA impression, FRAX risk, and osteoporosis knowledge, and examined their stated reasons for non-adherence. Results Mean age was 66.8 (SD = 8.9), 87.2% were women, and 84.2% were white. One-fourth (24.8%) reported that they did not start their recommended pharmacotherapy. In the unadjusted analyses, the only factor significantly associated with non-adherence was osteoporosis knowledge, with those having better knowledge less likely to take their medications (p < 0.05). The most common reasons for non-adherence were fear of side effects (53.3%), a dislike of taking medicine (25.3%), and the belief that the medicine would not help their condition (16.7%). Conclusion One in four patients recommended for osteoporosis pharmacotherapy declined treatment because they feared potential side effects, don’t like taking medicine, or felt that the medication would not help their condition. Improved patient counseling regarding the potential side effects of osteoporosis treatment and the risk-benefit ratio for these medications may increase adherence.

“…Brenneman et al developed the O&Y instrument using a convenience sample of 500 women who were equally distributed across five age groups (20–39, 40–49, 50–59, 60–69, and ≥ 70) [19]. After a qualitative evaluation for readability and understanding of items from previously used but not validated instruments, 20 items were chosen with a five-point Likert response set ranging from 1 (“strongly disagree”) to 5 (“strongly agree”).…”

“…The 10-item Osteoporosis and You ( O&Y ) instrument assesses osteoporosis knowledge and is said to be appropriate for use among older adults due to its brevity, simplicity, and varied knowledge domains [19, 20]. It was, however, developed and validated using a 20-item version among women 20 years old or older [19].…”

Summary We studied the Osteoporosis and You knowledge scale in 7749 participants enrolled in a clinical trial. Results confirmed its psychometric properties in a diverse audience. Baseline scores were associated with better recall of bone mineral density test results at follow-up; however, the scale was not responsive to knowledge change. Introduction The goal of this study was to confirm the measurement properties of the Osteoporosis and You (O&Y) knowledge scale using classic test theory methods in the 7749 men and women participating in the Patient Activation After DXA Result Notification (PAADRN) randomized controlled trial. We hypothesized a simple factor structure that would reflect the four-factor model previously published. Methods We conducted psychometric analyses which included item analysis, internal consistency reliability, construct validity using exploratory and confirmatory factor analysis (EFA and CFA), comparing knowledge levels across pre-specified groups, and responsiveness to change. Results PAADRN participants were predominantly college educated, White females with low bone density, and a moderate level of 10-year fracture risk. EFA revealed four domains closely matching those in two previous reports. While overall scale reliability was minimally acceptable at 0.68, the reliabilities of the domain subscales were unacceptably low (0.59, 0.64, 0.45, and 0.36 for the Biological, Lifestyle, Consequences, and Prevention and Treatment subscales). CFA revealed the data fit the hypothesized model reasonably well with the items loading on their expected latent variable. The scale was not responsive to change, but although not significant, improved knowledge indicated better DXA result recall at 12 and 52 weeks. Conclusions In the PAADRN population, the O&Y knowledge scale had psychometric properties similar to those previously reported. Over 12 and 52 weeks, participants did not demonstrate significant changes in knowledge, but those with higher knowledge at baseline were more likely to accurately recall their baseline DXA result.

BackgroundUndiagnosed, or diagnosed and untreated osteoporosis (OP) increases the likelihood that falls result in hip fractures, decreased quality of life (QOL), and significant medical expenditures among older adults. We tested whether a tailored dual energy x-ray absorptiometry (DXA) test result letter and an accompanying educational bone-health brochure affected patient satisfaction, QOL, or OP knowledge.MethodsThe Patient Activation after DXA Result Notification (PAADRN) study was a double-blinded, pragmatic, randomized trial which enrolled patients from 2012 to 2014. We randomized 7,749 patients presenting for DXA at three health care institutions in the United States who were ≥ 50 years old and able to understand English. Intervention patients received a tailored letter four weeks after DXA containing their results, 10-year fracture risk, and a bone-health educational brochure. Control patients received the results of their DXA per the usual practices of their providers and institutions. Satisfaction with bone health care, QOL, and OP knowledge were assessed at baseline and 12- and 52-weeks after DXA. Intention-to-treat analyses used multiple imputation for missing data and random effects regression models to adjust for clustering within providers and covariates.ResultsAt 12-weeks 6,728 (86.8 %) and at 52-weeks 6,103 participants (78.8 %) completed their follow-up interviews. The intervention group was more satisfied with their bone health care compared to the usual care group at both their 12- and 52-week follow-ups (standardized effect size = 0.28 at 12-weeks and 0.17 at 52-weeks, p < 0.001). There were no differences between the intervention and usual care groups in QOL or OP knowledge at either time point.ConclusionsA tailored DXA result letter and bone-health educational brochure sent to patients improved patient satisfaction with bone-related health care.Trial registrationClinical Trials.gov Identifier: NCT01507662 First received: December 8, 2011.
