REGRESSION
The data were initially assessed to remove duplicate participants as well as participants who took over two hours to complete the study and those who incorrectly answered questions assessing attentiveness and comprehension. Data were analyzed using SPSS version 28. To assess within- and between-condition differences, we performed repeated-measures ANOVAs on state mindfulness, state anxiety, negative affect, and positive affect. Time (i.e., pre- vs. post-intervention) was entered as a within-subjects factor, while Condition (i.e., meditation vs. control) and Duration (i.e., 10 vs. 20 min, or “dose”) were entered as between-subjects factors. Individual within- and between-group differences were subsequently assessed with paired or independent-samples t-tests (note that we did not directly compare unmatched pairs of conditons, e.g., 20-min control vs. 10-min mindfulness).To evaluate moderators, we conducted moderated regression analyses using the PROCESS 4.0 macro (Model 1) with 5,000 bootstrapped samplesTo probe the nature of statistically significant moderation effects, we applied the Johnson-Neyman (JN) technique
