Reliability and validity of the revised Osteoporosis Knowledge Test

Changing Osteoporosis Knowledge and Behaviors Through Structured Education

Osteoporosis is a silent disease that is associated with enormous cost and can lead to disability and death. We identified that individuals who have sustained a fracture from a fall are often unaware of osteoporosis risk factors and have a knowledge deficit regarding osteoporosis. Therefore, they do not receive the proper treatment. An evidence-based practice project was completed using "pre-post" intervention tools with an educational intervention to measure osteoporosis knowledge and self-efficacy in individuals hospitalized with a fragility fracture. A convenience sample of 25 participants 50 years and older, who were admitted with a fragility fracture, received targeted education. Descriptive and comparative statistics were used for comparison of pre- and postintervention data. Hospitalized osteoporotic individuals have a gap in knowledge regarding the existence of osteoporosis. Healthcare workers can improve knowledge and self-efficacy by offering osteoporosis education for these individuals.

Osteoporosis knowledge and beliefs in diabetic patients: a cross sectional study from Palestine

BACKGROUND

Osteoporosis is a potential metabolic complication of diabetes mellitus (DM). Therefore, patients with DM should have adequate osteoporosis knowledge and beliefs in order to get engaged in osteoporosis preventive behaviors. The objective of this study was to assess osteoporosis knowledge and beliefs among diabetic patients.

METHODS

This was a cross sectional study carried out at Al-Makhfiah governmental primary healthcare unit in Nablus, Palestine from September 2016 to December 2016. The tools used to assess knowledge and beliefs were Osteoporosis Health Belief Scale (OHBS) and the Osteoporosis Knowledge Test (OKT) respectively.

RESULTS

Three hundred diabetic patients were interviewed regarding their knowledge and belief about osteoporosis. The study sample included 192 (64.0%) females. Mean ± standard deviation (SD) of the participants was 58.5 ± 9.3 years. Regarding co-morbidities, 229 (76.3%) had at least one co-morbidity other than DM. The majority of participants incorrectly answered 19 out of 32 questions of OKT scale. The mean OKT score was 13.5 ± 4.2 indicating poor osteoporosis - related knowledge. Females had significantly higher nutrition (p = 0.037), exercise (p = 0.043), and OKT score (p = 0.021) than males. Regarding OHBS, female participants had significantly higher belief score of susceptibility (p <  0.01) and seriousness (p <  0.01) of osteoporosis compared to males.

CONCLUSIONS

Diabetic patients had poor osteoporosis knowledge and moderate perception of susceptibility and seriousness of osteoporosis. These results require implementation of awareness programs among DM patients to increase their practices regarding preventive measures of osteoporosis such as calcium intake and exercise.

Validity, reliability, and responsiveness to change of the "Osteoporosis and You" knowledge scale

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.

Osteoporosis Preventive Practice Between Veteran and Nonveteran Older Adults: Findings From Patient-Reported Data

BACKGROUND

Veterans are prone to bone-related illnesses due to multiple risk factors such as prior injuries. The aim of this study was to compare trends in osteoporosis preventive practices between veteran and nonveteran older adults.

METHODS

This was a secondary data analysis using selected baseline data and discussion postings from an online bone health trial including participants (N = 866) recruited from My HealtheVet (MHV) and SeniorNet (SN). Data were analyzed using descriptive statistics, parametric statistics, and content analysis.

FINDINGS

Overall, MHV participants were younger and included more men than SN participants. However, they reported higher rates of bone health issues, spent less time exercising, took fewer calcium and vitamin D supplements, and were less likely to discuss bone health with their care providers. More MHV participants discussed pain and disability as barriers to bone health behaviors and fear of deteriorating health as motivators. In addition, more MHV participants found that participating in the original study was helpful for changing health behaviors.

CONCLUSION

Overall, the findings suggest a disparity in bone health between veterans and nonveterans and a significant potential for using eHealth programs for veterans.

The Effects of an Online Theory-Based Bone Health Program for Older Adults

An estimated 10 million Americans age 50 and older have osteoporosis, and many experience associated fractures. Although several interventions have been shown to be effective in preventing osteoporosis, their impact on bone health among older adults was limited. The aim of this study was, therefore, to examine the effects of a theory-based online bone health program (Bone Power program) for a large number of older adults. The 8-week program included learning modules, discussion boards, and other resources. Participants ( N = 866; M age = 62.5 years) were recruited online and randomized into a Bone Power or control group. At the end of the intervention, the Bone Power group showed significantly greater improvement over the control group in osteoporosis knowledge, self-efficacy/outcome expectations for calcium intake and exercise, and calcium intake and exercise behaviors. This study's findings suggest that online health programs can be effective in improving older adults' knowledge, beliefs, and health behaviors.

Psychometric evaluation of the Korean Version of the Self-Efficacy for Exercise Scale for older adults

We evaluated the psychometric properties of the Korean version of the Self-Efficacy for Exercise Scale (SEE-K). The SEE-K consists of nine items and was translated into Korean using the forward-backward translation method. We administered it to 212 community-dwelling older adults along with measures of outcome expectation for exercise, quality of life, and physical activity. The validity was determined using confirmatory factor analysis and Rasch analysis with INFIT and OUTFIT statistics, which showed acceptable model fit. The concurrent validity was confirmed according to positive correlations between the SEE-K, outcome expectation for exercise, and quality of life. Furthermore, the high physical activity group had higher SEE-K scores. Finally, the reliability of the SEE-K was deemed acceptable based on Cronbach's alpha, coefficients of determination, and person and item separation indices with reliability. Thus, the SEE-K appears to have satisfactory validity and reliability among older adults in South Korea.
