How to evaluate the effectiveness of mindfulness in reducing self-objectification and improving meaning in life?

Nice to learn it.

I appreciate your response.

Evaluating the effectiveness of mindfulness in reducing self-objectification and improving meaning in life includes:
1. Pre-post intervention measures: Administer validated scales (e.g., Objectified Body Consciousness Scale, Meaning in Life Questionnaire) before/after mindfulness programs (e.g., body scan meditation), comparing scores to control groups (e.g., relaxation exercises).
2. Experimental design with mediators: Test if mindfulness reduces self-objectification (e.g., via decreased body surveillance) and enhances meaning in life by measuring mediating factors like present-moment awareness or self-compassion during interventions.
3. Long-term follow-up: Track participants post-intervention to assess sustained effects, ensuring changes in self-objectification and meaning in life are not temporary while controlling for baseline traits (e.g., perfectionism, depression).
