In this article, the authors study the factorial structure of 2 versions (64 items and 32 items) of the Dutch translation of the Inventory of Interpersonal Problems (IIP; L. M. Horowitz, L. E. Alden, J. S. Wiggins, & A. L. Pincus, 2000) in both a clinical sample (n = 382) and a student sample (n = 287). First, the authors test whether both inventories are constituted by correlated uni-dimensional subscales, and they conclude that this is true only for the short version. Second, the authors study whether the correlations between the subscales follow a circumplex pattern. This proves to be true for both versions. Coefficients alpha and correlations between the IIP-64 and IIP-32 subscales are discussed.

The current study further validates the Quality of Relationships Inventory (QRI; G. R. Pierce, I. G. Sarason, & B. R. Sarason, 1991) by evaluating its factor structure in a sample of 572 partners from 286 couples. Confirmatory factor analysis was used to compare 3 different models of the QRI and to investigate the invariance of the factor structure of the QRI across gender and across relationship satisfaction. Analyses revealed that a 3-factor solution--consisting of 3 different but interrelated factors (a 7-item support factor, a 12-item conflict factor, and a 6-item depth factor)--best accounted for the data. The authors' findings suggest that full metric invariance holds across gender and across relationship satisfaction in the female subsample, whereas only partial metric invariance could be established for relationship satisfaction in the male subsample.
