A research study examining the effect of a therapeutic mattress on pressure ulcers in clients would likely be based on which type of theory?

The study examining the effect of a therapeutic mattress on pressure ulcers is grounded in predictive theory. Predictive theories aim to forecast future events or outcomes based on established relationships. In this context, the research seeks to determine whether the use of a therapeutic mattress might lead to a decrease in the occurrence or severity of pressure ulcers, thereby making predictions about the efficacy of this intervention.

In the realm of evidence-based practice, predictive theory plays a critical role. It allows researchers and practitioners to test hypotheses and anticipate the consequences of implementing certain interventions. When applied to clinical settings, such theories enable health care professionals to make informed decisions that are likely to benefit patients based on prior evidence and outcomes observed in similar scenarios.

Other types of theories differ in focus and application. Simplistic theories tend to offer broad, generalized explanations without delving into complex relationships. Descriptive theories, on the other hand, provide detailed descriptions of phenomena but do not aim to predict outcomes. Explanatory theories seek to clarify why things happen, focusing more on understanding the relationships and underlying mechanisms rather than projecting future events. In this case, since the primary goal is to predict the outcomes associated with using a therapeutic mattress, predictive theory is the most fitting choice.
