Note. IIP = Inventory of Interpersonal Problems; AVPD = Avoidant personality disorder traits; NPD = Narcissistic personality disorder traits; DPD = Dependent personality disorder traits. Expected r column is the relative size and valence of correlations, with ++ = largest and positive, + = significant and positive, 0 = near zero, − = significant and negative. These directional hypothesis columns concern only the sign and significance of the correlation, not whether the correlation is the largest; the latter point is taken up in detail in the text. Self-Report column is the correlation between the self-report of personality disorder traits and self-report of IIP subscales, and Peer-Report column is the correlation between peer-report of personality disorder traits and peer-report of IIP subscales. The Shared column is the correlation of the residualized shared variance factor scores (with self and peer factor scores partialled out). Due to sporadic missing data, n varies from 949 to 990 across cells.
