Two sets of constellations of DSM-III features were tested, each consisting of three groupings. The first set of constellations was constructed according to Clarkin's factor analysis; the second was theoretically derived. Broadly speaking, the three groupings concerned \u2018self\u2019, \u2018emotional regulation\u2019, and \u2018impulse\u2019. Changes of these constellations were charted over one year in a comparison of the effect of treatment by the Conversational Model (n = 29) with treatment as usual (n = 31). In addition, measures of typical depression (Zung) were scored before and after the treatment period. The changes in the constellations were considered in relation to authoritative opinion.<\/jats:p>\n                  <jats:p>Results: The changes in the two sets of constellations were similar. In the treatment as usual (TAU) group, \u2018self\u2019 endured unchanged, while \u2018emotional regulation\u2019 and \u2018impulse\u2019 improved. In the Conversational Model cohort, \u2018self\u2019 improved, \u2018emotional regulation\u2019 improved more greatly than the TAU group, while \u2018impulse\u2019 improved but not more than the treatment as usual group. Depression scores were not particularly associated with any grouping.<\/jats:p>\n                  <jats:p>Conclusions: A group of features including self\/identity disturbance, emptiness and fear of abandonment may be at the core of BPD. Correlations between the three groupings and Zung scores favoured the view that the core affect is not typical depression. Rather, the central state may be \u2018painful incoherence\u2019. It is suggested that the findings have implications for the refinement and elaboration of treatment methods in borderline personality disorder.<\/jats:p>","DOI":"10.3109\/00048674.2010.551280","type":"journal-article","created":{"date-parts":[[2011,2,25]],"date-time":"2011-02-25T09:15:58Z","timestamp":1298625358000},"page":"214-222","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":71,"title":["Is Self Disturbance the Core of Borderline Personality Disorder?
