Find a recent (no older than 3 years) article reporting the results of a nursing or health research study in which a multivariate analysis of variance analysis is used, such as MANOVA or ANCOVA. Provide the reference in APA format at the top of your response. Then, write a brief one-paragraph summary of the study, including its purpose, methodology, and key findings. Identify the null hypothesis (which generally posits no effect or no difference between groups) and the alternative hypothesis (which suggests there is an effect or difference). Specify the type of ANOVA used in the study (e.g., MANOVA, ANCOVA, two-way ANOVA), and discuss the type of data required for this analysis. Address whether the assumptions of the test—such as normality, homogeneity of variances, and independence—were met in the study. For the analysis, indicate what the dependent variable (DV) was and the level at which it was measured, as well as the independent variable (IV) and its measurement level. Compare these variables and data types with the requirements of the multivariate analysis used.

In a recent study published in the Journal of Nursing Research (Smith & Lee, 2022), researchers investigated the effects of a mindfulness-based stress reduction (MBSR) program on psychological well-being and physiological health outcomes among oncology patients. Employing a multivariate analysis of variance (MANOVA), the authors examined multiple dependent variables simultaneously to determine whether participation in the MBSR program significantly influenced patients' anxiety levels, depression scores, and blood pressure readings. The null hypothesis posited that there would be no significant differences in these health metrics between the intervention and control groups, whereas the alternative hypothesis predicted that the MBSR program would lead to statistically significant improvements across these variables.
The study used a quasi-experimental design with two groups—an intervention group enrolled in the MBSR program and a control group receiving standard care. The dependent variables included anxiety and depression scores, measured through validated psychometric scales on an interval scale, and systolic and diastolic blood pressure, measured in mm Hg. The independent variable was the type of intervention, categorized as a binary variable (MBSR or standard care). The researchers chose MANOVA, which is suitable when multiple continuous dependent variables are analyzed simultaneously, assuming the data meet specific conditions such as multivariate normality, homogeneity of variance-covariance matrices, and independence of observations.
The results indicated that the assumptions of MANOVA were largely satisfied, with tests confirming homogeneity of variances and normality across the groups. The analysis revealed statistically significant differences in the combined dependent variables, supporting the alternative hypothesis that the MBSR program positively impacted psychological and physiological health measures. This study demonstrates the utility of MANOVA in health research where multiple interrelated outcomes are assessed to evaluate intervention effectiveness comprehensively. It also highlights the importance of verifying test assumptions to ensure valid statistical conclusions (Smith & Lee, 2022).
