IMO, group dynamic treatment for all forms of BPD is real good idea, but for the mainly "petulant" type of BPD it's an absolute mandate. I say this because the "petulant" BPD is the most ardently defended with ostensibly "*conscious*" and "rational" beliefs, values, ideals, principles, convictions, rules, codes, regulations and requirements about how things should / must / ought / have to be... and therefore the most argumentative vs. the "impulsive," "self-destructive" and "discouraged" types. (Yes; I know *personally*: All four types have UNconscious beliefs in bundles that control their/our emotions and behaviors.) 

This notion is built not only on decades of observing myself and other borderlines in early, middle and long-term recovery, but also on observing the dynamics of how recovery is prodded along in the 12 Step programs of the more in-your-face type. In Alcoholics and Narcotics Anonymous, for example, such notions as "denial," "stinking thinking," "self-righteousness," "playing the victim" and the "pity party" are regularly brought up in open sharing of self-recognized barriers to recovery. And those who are more recovery-resistant sometimes move (along the five stages of recovery) from denial / pre-contemplation up to contemplation / consideration and even acceptance / identification  when they hear such presentations by "peers" in the group.
