This experimental study explored the use of online expressive writing interventions to cope with distress from heterosexist events among a sample of autistic-LBGQ + individuals. This study included an open writing condition and an emotion focused therapy guided writing condition. Over 89% of the participants indicated that the writing exercises were helpful in processing the event, with significant decreases for measures of depressive and trauma/stressor symptoms. A thematic analysis identified specific aspects of each condition that were helpful for participants in coping with heterosexist distress, such as the development of insight through the emotion-focused exercises. This low-demand exercise is promising as a solo exercise or as a therapy homework assignment, especially given the accessibility of this online intervention for autistic-LGBQ + people.
