SELF-CARE MANAGEMENT TO PREVENT READMISSION

Data Analysis

Pre-test and a post-test evaluation were conducted to determine whether education impacted the management of bipolar disorder. A bipolar management scale was used to determine the management level of the condition. The scale ran from 1 to 5. The lower scores meant poor management level, whereas higher scores indicated good or excellent managerial skills. A random sample of 15 staff was picked for the pre-tests and post-test analysis. The data from the post-test and pre-test are shown below.
