This study sought to confirm a multi-factor model of Obsessive-compulsive personality disorder (OCPD) in a Hispanic outpatient sample and to explore associations of the OCPD factors with aggression, depression, and suicidal thoughts. One hundred and thirty monolingual, Spanishspeaking participants were recruited from a community mental health center and were assessed by bilingual doctoral level clinicians. OCPD was highly prevalent (26%) in this sample. Multi-factor models of OCPD were tested and the two factors -perfectionism and interpersonal rigidity -provided the best model fit. Interpersonal rigidity was associated with aggression and anger while perfectionism was associated with depression and suicidal thoughts.
KeywordsObsessive-compulsive personality disorder; Hispanic; perfectionism; rigidity Obsessive-compulsive personality disorder is one of the most prevalent personality disorders (PDs) in community and outpatient samples. Some studies suggest it has the highest prevalence rate (7.9%) of all PDs in community samples and one of the highest rates (8.7%) in outpatient groups (Grant, et al., 2004;Zimmerman, Rothschild, & Chelminski, 2005). Despite the high prevalence of OCPD, little empirical attention has been given to the validity and structure of the OCPD construct as outlined in DSM-IV (Pollak, 1995). The DSM-IV assumes a unidimensional structure for each of the personality disorder diagnoses. However, clinical views and the limited empirical literature suggest that a multifactorial approach may offer a Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

NIH Public AccessTheoretical underpinnings of OCPD highlight the mutlifactorial nature of the diagnosis. Descriptions of OCPD have emphasized deliberateness and effortfulness (Shapiro, 1965) control over self and environment (Salzman, 1973), and the interpersonal rigidity associated with a demanding and uncompromising standards (Millon, 1981) (Pulay, et al., 2008;Villemarette-Pittman, Stanford, Greve, Houston, & Mathias, 2004).Exploratory and confirmatory examinations of factor structure in OCPD to date have suggested two-and three-factor solutions (see Table 1). Grilo (2004), in an exploratory factor-analytic study of DSM-IV OCPD criteria, identified a three-factor structure of OCPD in a homogeneous binge eating disorder (BED) patient group. Examinations of factor loadings suggested that perfectionism, rigidity, and miserliness factors underlie the OCPD construct. However, Grilo ...
