Mindfulness has demonstrated benefits for the mental health of college students, but studies of its effectiveness when delivered online are still needed, particularly in Latin American countries.To investigate the effects of a synchronous online version of an adapted Mindfulness-Based Relapse Prevention (MBRP) protocol on perceived stress, depression, anxiety, insomnia, and self-care in Brazilian college students. A randomized controlled trial was conducted, with undergraduate students allocated to an 8-week Experimental Group (EG = 47) who used the online MBRP or a waiting list Control Group (CG = 65). Pre- and post-intervention assessment was undertaken using the following instruments: the Insomnia Severity Index (ISI); Perceived Stress Scale (PSS-10); Patient Health Questionnaire-9 (PHQ-9); State-Trait Anxiety Inventory (STAI); and the Scale for Appraisal of Self-Care Agency Scale (ASA- A). Significant decreases were found in scores for anxiety (-6.21 95% CI = − 9.98; -2.44; p = < 0.001), depression (-3.52 95% CI = (-5.24; -1.79; p = < 0.001), perceived stress (-4.76 95% CI = 4.04; 8.92; p = < 0.001), insomnia (-4.13 95% CI = -6.22; -2.03; p = < 0.001) and increased scores in respect of self- care practices (7.65 95% CI = 4.03; 11.17; p = < 0.001), compared to baseline levels. The results indicate that the online version of the MBRP benefits various aspects of the mental health of Brazilian college students.
