Factorial Validity of the Decisional Involvement Scale as a Measure of Content and Context of Nursing Practice.

Decisional involvement is widely recognized as an essential component of a professional nursing practice environment. In recent years, researchers have added to the conceptualization of nurses' role in decision-making to differentiate between the content and context of nursing practice. Yet, instruments that clearly distinguish between these two dimensions of practice are lacking.

Severe Symptomatic Aortic Stenosis in Older Adults: Pathophysiology, Clinical Manifestations, Treatment Guidelines, and Transcatheter Aortic Valve Replacement (TAVR).

The only effective treatment for symptomatic aortic stenosis in the older adult population is surgical aortic valve replacement. However, more than 30% of candidates are denied surgery due to advanced age and multiple comorbidities. Without surgical intervention, death from symptomatic aortic stenosis approximates 2% per month, with mortality rates of approximately 50% within 2 years of symptom onset.

The use of self-generated identification codes in longitudinal research.

Longitudinal research designs involve data collection at multiple time points to measure change over time. Therefore, identification of the same respondents is essential at each time point so that data from the same respondents can be matched for comparison over time. Subject-generated identification codes permit an anonymous means to track respondents over multiple data collection points.
