A Mindfulness-Based Intervention: Differential Effects on Affective and Processual Evolution.
Study Goal
The researchers aimed to evaluate the effects of a 20-minute daily mindfulness intervention on affective and functioning variables and assess improvement potential based on baseline mindfulness levels.
Results Summary
The mindfulness group showed improvements in anxiety, depression, psychological distress, mindfulness, negative self-oriented cognition, and experiential avoidance, with effect sizes ranging from .53 to .88. Participants with lower baseline mindfulness levels experienced greater improvements.
Population
French community sample (non-randomized, n = 91 total: 47 mindfulness group, 44 control group).
Effective Dosage
20 minutes per day.
Duration
6 weeks.
Interactions
None mentioned.

mindfulness-based intervention | increase | affective variables | French community sample | - | elicited several positive outcomes | #2 |
mindfulness-based intervention | increase | emotional functioning | French community sample | - | highlighting emotional functioning changes | #3 |
mindfulness-based intervention | increase | mindfulness | participants with low baseline levels of mindfulness | r = -0.55 | Low baseline levels of mindfulness predicted greater improvement | #4 |
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. METHOD: Participants were non-randomly assigned to a control group on the waiting list (n = 44) or a mindfulness group (n = 47). Self-report measures assessed anxiety, depression, psychological distress, mindfulness, negative self-oriented cognition, and experiential avoidance. RESULTS: Improvements in the variables were observed for the mindfulness group but not for the control group, with effect sizes ranging between .53 and .88. Low baseline levels of mindfulness predicted greater improvement in mindfulness (r = -0.55, p < .001) than high baseline levels. CONCLUSIONS: Mindfulness practice elicited several positive outcomes regarding affective variables, highlighting emotional functioning changes.
