SCENARIO: A small hospital uses a standardized test to measure depression. The psychometric properties of the test are Cronbach alpha of .48 and a test-re-test of .25. The test has a concurrent validity with another well-used test of .50. With so many current concerns of depression in adolescent girls, a nurse decides to conduct a study to determine if a nationally acclaimed intervention program for depression, Live Happy, could reduce the incidence of depression. The nurse develops a proposal that...

This research aimed to evaluate whether a self-management program promoted healthy lifestyle behaviors (HLBs) and improved health outcomes among Thai elderly with hypertension. Participants were randomly allocated to either an intervention group (n= 20), that received an 8-week selfmanagement program that included home visits, or a control group (n=20). The data were analyzed by a chi-square analysis, a mixed-model repeated measure MANOVA, and MANCOVAs. There were significant differences in the mean scores of healthy lifestyle behaviors at posttest and follow-up...
