2.3.8. Anger

The Dimensions of Anger Reactions-5 (DAR-5; Forbes et al., 2014) measures anger using 5 items. Patients rate the extent to which they experienced anger (e.g., “I found myself getting angry at people or situations”) over the past four weeks on a scale from 1 (none or almost none of the time) to 5 (all or almost all of the time). Items are summed for a total score (possible range of 5–25), with higher scores corresponding to greater anger. A cut-score of 12 or greater reflects high anger. Internal consistency was high at baseline (α = 0.86), 1-month (α = 0.88), and 6-months (α = 0.92).
