A Mindfulness-Based Intervention: Differential Effects on Affective and Processual Evolution.

Objectives: A 20-minutes-a-day, self-help, mindfulness-based intervention was conducted for 6 weeks with a French community sample. First, the intervention effects on affective and functioning variables were evaluated. Then, a differential approach was used to examine improvement potentiality and the perceived benefits of mindfulness according to the participants' baseline mindfulness competencies.

Rumination and Mindlessness Processes: Trajectories of Change in a 42-Day Mindfulness-Based Intervention.

This preliminary study aimed to understand the effects of an autonomous mindfulness-based intervention (MBI) on mindlessness propensities: rumination, automatic pilot functioning, and attentional distractibility. The ecological momentary assessment was completed by community participants assigned to two nonrandomized groups: an experimental group ( = 45) that practiced 20-minute daily mindfulness meditation for 42 days and a control group ( = 44) that was on the waiting list for the MBI. All participants completed a self-assessment on rumination and mindlessness propensities twice a day.
