Objective Colorectal cancer survivors are at risk of symptom burden and emotional distress. Dispositional mindfulness has been linked with better sleep quality and quality of life (QoL) in these patients. This longitudinal study aimed to examine the associations among mindfulness facets, symptom burden, emotional distress, and functional outcomes. Methods Study sample of this three‐wave, 2‐month survey was 127 Chinese colorectal cancer survivors. The participants completed the Five Facet Mindfulness Questionnaire, Memorial Symptom Assessment Scale, Perceived Stress Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and SF‐12 health survey. Moderated mediation analyses examined the direct and indirect effects of mindfulness facets on QoLs and sleep quality via symptom burden and emotional distress, using acting with awareness as a moderator. Results The mindfulness facets had no significant direct effects on functional outcomes 2 months later. Awareness and nonreacting showed significant and positive indirect effects on physical and mental QoL via symptom burden and emotional distress 1 month later, respectively. Awareness, nonjudging, and nonreacting significantly predicted better sleep quality indirectly via emotional distress. Nonreacting showed stronger indirect effects on the functional outcomes among patients with greater awareness. Conclusions This study demonstrates longitudinal linkages between dispositional mindfulness and functioning in cancer survivors via symptom burden and emotional distress. Acting with awareness and nonreacting are the two facets that displayed clinical relevance in predicting better sleep quality and QoL.
