I've been looking into whether there were effective interventions to increase distress tolerance. I assume I'm not the first one to look into this topic and to my surprise I've found quite little on LessWrong.

Do people know of good literature (e.g. meta-analysis) and/or good interventions that increase distress tolerance? 

Personal experience or anecdotes from people who dived into this topic are allowed. Takes on the validity of the literature are welcome.

Suggestions of useful related concept & literature are also very much welcome.
