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

The two provided Excel books contain:<br>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 <i>Methods/Data Processing and Statistical Analysis</i> section of the manuscript, as well as the <i>Measures </i>subsection under <i>Materials and Methods</i> 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.<br>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.<br>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.

本次提供的两份Excel工作簿包含如下内容：<br>1. 支撑本研究核心结论的匿名化处理后数据集（工作表1），及其配套的编码表（工作表2）。为构建该数据集，我们从整体结局指标数据中筛选出了统计分析实际用到的数值——即各核心指标（正念（mindfulness）、幸福感（wellbeing）、情绪失调（emotional dysregulation）、心理困扰（psychological distress）及人际沟通表现（interpersonal communication performance））的整体前测、后测与差值得分。上述汇总值的获取流程详见论文的《方法/数据处理与统计分析》章节，以及在线补充材料中《材料与方法》项下的《测量工具》小节。针对经过异常值调整的变量，数据集末尾附带了其未经缩尾处理的原始值以供参考。本研究还提供了用于协方差分析（ANCOVA）及多元协方差分析（MANCOVA）的经信度校正后的前测值。完整的未处理前测与后测指标数据，可按合理要求向通讯作者申请获取。<br>2. 包含早期终止问卷（Early Termination Questionnaire，ETQ）作答数据的匿名化处理后数据集（工作表1），及其配套的编码表（工作表2）。该问卷面向未完成正念干预的参与者发放，用于评估其对项目的趣味性与实用性评价、未来是否愿意重新参与并完成该项目，以及其提前退出的主要原因。<br>注意：所有相关问卷条目及编码答案的文本均为英文。但参与者提交的任意自由文本作答均保留其原始西班牙语版本。
