Rumination is a vulnerability factor for the onset and maintenance of emotional distress. This study examined whether writing about life goals is associated with a decrease in ruminative thinking and a reduced cortisol awakening response. 68 healthy participants either wrote about their personal life goals or a control topic. Writing about life goals was associated with a modest decrease in ruminative thinking and a reduced cortisol awakening response at the post-intervention assessment. Results provide initial evidence that writing about life goals can be a helpful aid in decreasing rumination and physiological stress reactivity.
