Study Design
Identify the specific design of the study. Was the best design selected to direct this study?
The authors use the descriptive correlational design and cross-sectional approach in their study. True to the definition and purpose of a descriptive correlation design, the study describes the variables and examines the relationships among these variables. The design facilitates the identification of the many interrelationships that exist in the nurses’ sense of empowerment and positive patient satisfaction. In addition, the researchers make no attempt to control or manipulate the environment of the study, neither do they attempt to change the behavior of the participants (Grove, et al., 2015).

“A convenience sample of 259 nurses was obtained from all active-status, registered nurses employed at the study hospital” (Donahue, et al., 2008, p. 3). Some advantages of convenience sample are sample availability, accessibility, requires little time and effort, and cost effectiveness for the researchers, thus, the word convenience. However, sampling method suffers from a major disadvantage that relates to inaccurate representation of the population, which can distort results (Wisegeek, n.d.). The authors cite that the sampling method used pose a limitation to the study. The study sample includes only nurses who were employed in the study hospital that chose to answer the CWEQ-II (Donahue, et al., 2008). In the same manner, the authors added that the Press Ganey survey, which is voluntary, may not represent the entire patient population who were cared for at the time of the data collection (Donahue, et al., …show more content…
Are The Reliability And Validity Of The Instruments Described? Did The Researcher Examine The Reliability And Validity Of The Instruments For The Present Sample? The reliability and validity of the instrument (CWEQ-II) that was used to measure nurse empowerment shows a construct validity that is substantiated in a confirmatory factor analysis that revealed a good fit of the hypothesized factor structure (RMSEA = .054) (Donahue, et al., 2008). The instrument also correlated highly with the global measure of empowerment (r = 0.56) (Donahue, et al., 2008). For the Press Ganey patient satisfaction scales, the authors indicate that the “Cronbach’s alpha values for each of the subscales ranged from -84 to .95. The reliability value for the overall questionnaire was reported to be .98” (Donahue, et al., 2008, p. 3). Using the factor analysis, the construct validity of the surveys was evaluated, the results of which confirmed the convergent and discriminate validity of the instrument (Donahue, et al.,
