The purpose of this paper is to critique, contrast, and compare two research studies.
“Assessment of Anxiety in Intensive Care
Patients by Using the Faces Anxiety Scale” written by McKinley, Stein-Parbury,
Chehelnabi, & Lovas will be referred to as study one (2004). “Prevalence of Limited
Health Literacy and Compensatory Strategies

Study two
› Literature review followed the introduction
› Introduced results from eleven studies that

› Not critically analyzed, merely reported without critique
› Brings the reliability and validity of this study into question (“Quantitative Research
Critique,” n.d.).
