I'd guess it depends whether the pattern of issues that unfolds for you with people, or just inside yourself, has been understand fully enough and is being changed. Is this based on any particular causal model of that for you individually?

I guess behavioural activation might claim/intend to do that, but only deal with a narrow subset of the pattern, at the level of observable 'symptoms'. So really could be not much different to, oh just think/do positive and stop doing that negative stuff?
