Datasets and code tables for research project: Metacognition-Intensive Mindfulness training delivers superior clinical and quality-of-life outcomes via enhanced mindful self-regulation

1. The anonymized, processed dataset supporting the main findings of the study (Sheet 1), along with its corresponding code table (Sheet 2). To create this dataset, the overall outcome measure data were subsetted to include only the values actually employed in the statistical analysis -- global pretest, posttest and difference scores for each of the main measures (mindfulness, wellbeing, emotional dysregulation, psychological distress and interpersonal communication performance). The procedures used for obtaining these summatories are described in the Methods/Data Processing and Statistical Analysis section of the manuscript, as well as the Measures subsection under Materials and Methods in the online supplement. For those variables that had undergone outlier adjustment, their original, non-winsorized values are included at the end of the dataset for reference. The reliability-corrected pretest values used for the ANCOVA and MANCOVA analyses are also provided. Complete, unprocessed pretest and posttest measures data are available from the corresponding author upon reasonable request.

2. The anonymized, processed dataset containing responses to the Early Termination Questionnaire (Sheet 1), along with its corresponding code table (Sheet 2). The ETQ survey administered to those participants who did not complete the mindfulness intervention, to assess how interesting and useful they had found the program, whether they would like to retake and complete it in the future and their main reason for dropping out early.

NOTE: The text for any relevant survey items and coded answers appears in English. Any free text responses by the participants, however, are given in their original Spanish version.
