Please help me with my statistics... I am using 5 different dimensions to interpret the correlation among them. For instance, Burnout is negatively related to engagement. All dimensions have at least 3 Lickert scale data. Now, I would interpret the analysis among them, trying with one-way ANOVA but the post hoc test is not performed for Burnout because at least one group has fewer than two cases. Even though, I have significant correlation p=0.001. Can anybody suggest an alternative analysis or what I am doing wrong?

Thank you very much for the answers!
