REGRESSION
Figure Conceptual diagram of the moderation analyses. Intervention was the independent variable, neuroticism, prior meditation experience, and trait mindfulness were moderating variables, and state mindfulness, anxiety, and positive and negative affect were dependent variables.Trait mindfulness moderated the effects of meditation (mindfulness conditions vs. control) on changes in state mindfulness. Dotted lines represent 95% Johnson-Neyman confidence intervals. Region of significance is where the confidence intervals do not cross zero and is below 3.23, such that mindfulness meditation versus control predicted significantly greater increases in state mindfulness when trait mindfulness was below 3.23.Trait mindfulness moderated the effects of meditation duration (20- vs. 10-min mindfulness meditation) on changes in state anxiety. Dotted lines represent 95% Johnson-Neyman confidence intervals. Region of significance is where the confidence intervals do not cross zero and was above 3.48, such that the 20- versus 10-min mindfulness meditation predicted greater decreases in state anxiety when trait mindfulness was above 3.48.Results of moderated regression analyses with meditation (10- or 20-moinute) versus control (10- or 20-min) as the predictor variable.Bolded numerals indicate a statistically significant interaction.Results of moderated regression analyses with 20- versus 10-min mindfulness meditation as the predictor variable.Bolded numerals indicate a statistically significant interaction.
