A 14-year-old boy with depression describes himself as 'a total loser who will never amount to anything.' His narrative therapist begins referring to the depression as 'the bully in your head' and asks, 'When did the bully first start pushing you around? Are there times you've been able to stand up to it?' The therapist then collaboratively explores moments in the boy's life that contradict the depression's dominant story. Which narrative therapy techniques are being used?
