Article Abstract

Objective: Our objective was to develop an instrument that can measure outcome expectations of yoga and to evaluate the instrument for internal consistency and initial construct validity.

Methods: A 20-item scale was developed to assess physical, mental, and spiritual health benefits related to yoga practice among adults. The scale was tested in a baseline survey with adults participating in a clinical trial. Principal component analysis was used to investigate the internal structure of the measure. Outcome expectations for yoga were examined for demographic differences.

Results: The sample (N = 185) was 54% women, 89% white and had a mean age of 46 years. The final 20-item scale had high item loadings that ranged from .57 to .88 with a Cronbach's alpha value of .96. Significant differences were found in outcome expectation score by sex.

Conclusion: This newly developed scale can be used to assess outcome expectations for yoga and tailor interventions to promote adherence to yoga practice.

Importance: Advances in diagnostics have enabled the detection of more gastrointestinal pathogens, but misuse of diagnostics can lead to inappropriate antibiotic use and excess financial burdens. Ensuring appropriate use of diagnostics is crucial for optimizing patient care and promoting stewardship of health care resources.

Background: Talus fractures are rare injuries. To date, there is limited literature on outcomes after modern operative treatment of talus fractures. Many prior studies are limited by a small number of patients, limited follow-up, and include radiographic outcomes only.

Efforts to determine the relationship between patient reported outcome measures (PROM) and patient reported improvement has been largely focused on determining threshold values to classify patients as having experienced a certain amount of improvement or satisfaction. While these metrics aid in understanding the extent to which specific PROM scores associated with improvement vary across studies, they are imperfect thresholds sensitive to the practice and setting in which they were estimated. Even when applied to the patients that contributed to their estimate, thresholds misclassify patients.

Background: Loss of breast sensation following mastectomy and reconstruction significantly impacts quality of life, influencing body image, intimacy, and overall emotional well-being. Despite advances in reconstructive techniques, sensory outcomes remain inconsistent, limiting broader clinical adoption of reinnervation strategies. This educational review synthesizes the current scope of sensory restoration in breast reconstruction, examining approaches to reinnervation, sensory outcome measures, and management of patient expectations.
