Exercise 28 - Research Article Source: Zalon, M. L. (2004). Correlates of recovery among older adults after major abdominal surgery. Nursing Research, 53 (2), 99–106

Following questions need to be answered based un case as per attached detaiiles:

1.  Was multiple regression analysis the appropriate analysis technique to conduct in this study? Provide a rationale for your answer.

2.  Which independent variable had the strongest correlation with self-perception of recovery at 1 month after discharge? Provide a rationale for your answer.

3.  Were the independent variables pain, depression, and fatigue significantly correlated with self-perception of recovery at 1 month after discharge? Provide a rationale for your answer.

4.  Did multicollinearity occur in this study? Provide a rationale for your answer.

5.  Did the regression results indicate that pain, depression, and fatigue provided a greater prediction of self-perception of recovery at 1 month after discharge, or at 3–5 days post-discharge? Provide a rationale for your answer.

6.  What was the percentage of variance explained by the regression analysis for self-perception of recovery at 1 month after discharge? Provide your calculations.

7.  What was the percentage of variance explained by the regression analysis for functional status at 1 month after discharge? Provide your calculations.

8.  Was the percentage of variance explained for self-perception of recovery lower than the percentage of variance explained for functional status at 1 month after discharge? Discuss the meaning of these results.

9.  Discuss the multiple regression analysis results for self-perception of recovery following discharge. What do these results indicate for practice?

10.  Are these results ready to be generalized to older adults after other types of surgery, such as joint replacement? Provide a rationale for your answer.
