Objective The internal consistency, test-retest reliability and validity of the Self-report Standardized Assessment of Personality-abbreviated Scale (SAPAS-SR) as a screening instrument for personality disorders were studied in a random sample of 195 Dutch psychiatric outpatients, using the Structured Clinical Interviews for DSM-IV Personality Disorders (SCID-II) as a gold standard. Method All patients completed a self-report version of the SAPAS. One week later, they were interviewed with the SCID-II. Two weeks later, the SAPAS-SR was re-administered. Results According to the SCID-II, 97 patients (50%) were suffering from a personality disorder. The SAPAS-SR correctly classifi ed 81% of all participants. Sensitivity (0.83) and specifi city (0.80) were slightly lower compared with the original English version. This difference may be explained by the lower prevalence and severity of personality disorders in the study population. Conclusion The results provide evidence for the usefulness of the SAPAS as a self-administered instrument for screening personality disorders in clinical populations.
Identifying personality disorders: Towards the development of a clinical screening instrument
Comprehensive Psychiatry, 2000
gain is used to determine the diagnostic threshold (DT). Initially, 15 of 45 criteria are identified. At the 0.43 PD prevalence, a DT of 2 or more of the 15 PD criteria across samples is optimal. The maximum information gain (MIG) is .42 bits, and the AUR is 0.94 + .007. Other performance indices at this cutoff are .90 sensitivity, 64 specificity, .81 positive predictive power (PPP), .91 negative predictive power (NPP), and .86 hit rate (HR). Taken collectively, the 15 PD criteria selected by the data reduction techniques suggest a narrowed set to be assessed in screening for the presence or absence of any PD with comparable or better psychometric properties than other tests routinely used for diagnosing medical and psychiatric disorders. If specific PD categorization is needed, a second-step comprehensive assessment should follow.
Psychometric properties of a brief inventory for the screening of personality disorders: The SCATI
Psychology and Psychotherapy: Theory, Research and Practice, 2010
The purpose of the present study was to report on the psychometric properties of a revised version of abrief inventorydesigned to screenand assess personality disorders. The shortform of the Coolidge Axis II Inventory(SCATI) is a70-item, self-report, form of the 250-item Coolidge Axis II Inventory(CATI). On ac ommunity sample of 588 adults (range ¼ 16-88years), the median internal scale reliability for the 14 personality disorder scales was .66, and the median test-retest reliability (1 week) was .83. Principal components analysis (PCA) revealed afour-component structure, essentially similar to previous PCAstudies of the SCATIand CATI. Good convergent validity was obtained between afive-factor model of psychopathologyand the 14 SCATIpersonality disorder scales. Gender differences wereo btained on some scales, although the effect sizes wereg enerally small. These preliminaryp sychometric properties establish that the SCATIh as sufficient reliability and validity to warrant further research, particularly in clinical samples. Personality disordersa re among the most debilitating yet poorly understood forms of mental illness (e.g., Millon, Grossman, Millon, Meagher, &R amnath, 2004; Segal, Coolidge,&Rosowsky,2006), yettheir assessment is critically important forclinicalcase formulation and treatment planning, and critically important to prognoses of other comorbidd isorders(e.g., Coolidge&Segal, 1998).T he 250-item,s elf-reportC oolidge Axis II Inventory(CATI) wasd esigned to measure personality disorders strictly according to the specific criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR ;A mericanP sychiatric Association, 2000). The CATI also measures several Axis Isyndromes and neuropsychological dysfunction (e.g., Coolidge, 2005; Coolidge&Merwin, 1992).The purpose of the present study is to report on the psychometric properties of arevised, shortf ormofthe CATI (SCATI) with the specific purposeofscreening forand assessing only personality disorders, 10 from DSM-IV-TR,2 from Appendix Bo ft he DSM-IV-TR (depressive and passive-aggressive), and 2f rom DSM-III-R (American Psychiatric Association, 1987; sadistic and self-defeating) and to
SCREENING MEASURES FOR PERSONALITY DISORDERS
Romanian Journal of Experimental Applied Psychology, 2016
Personality disorders are psychiatric disorders characterized by chronic patterns of inner experience and behavior that are inflexible and present across a broad range of situations. This paper reviews some common assessment instruments for personality disorders, as: Shedler-Westen Assessment Procedure (SWAP II), Standardised Assessment of Personality – Abbreviated Scale (SAPAS), Iowa Personality Disorder Screen (IPDS), Inventory of Interpersonal Problems-Personality Disorders-25 (IIP-PD-25) and Five Factor Model Rating Form (FFMRF).

A brief screening for personality disorders: Clinical and one nonclinical sample
2015
Brief screening instruments for personality disorders could potentially have great value in community and clinical settings.This is a correlational study. One purposeful community sample (N=399; 299 teachers of primary and secondary schools in Pristina and 100 students of the European University of Tirana) and one clinical sample (N=41; patients of one private clinic) filled out the IIP-PD-25 questionnaire . They were randomly selected. All data was analyzed by SPSS 21 and Excel 2007.PD index screen resulted with Personality Disorder definite score 29.2% of community sample (12.5 % male vs. 16.7 % females) vs. 43.9 % of clinical sample (7.3 % male vs. 36.6 % females). Age (youngest) and residence (urban) showed significant negative correlations only for the community sample. Mann-Whitney U test did not find statistically significant differences regarding levels of PD screen index based on gender in the both samples; the same case was for differences regarding levels of PD screen index between community and clinical samples, despite the higher levels in the clinical sample. Clinical cases showed significantly higher score for the following dimensions of interpersonal sensitivity, aggression, needs for social approval and lack of sociability. Only in the case of interpersonal ambivalence, the community sample scored higher.

The Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II Version 2.0) is becoming the most favoured instrument to measure personality disorder but takes up to an hour to complete. The Standardized Assessment of Personality (SAP), an informant-based measure, takes 10 to 15 minutes to complete. Both instruments have been validated independently. This study aimed to determine whether the SAP is a suitable screening instrument for personality disorder as measured by the SCID-II. Fifty-seven psychiatric patients were assessed for personality disorder using both the SAP and the SCID-II. The SAP assessments were conducted blind to the results of the SCID-II assessments. Agreement between the two instruments in this population was low (kappa = 0.3). The level of agreement differed between personality disorder categories, ranging from kappa = 0.4 (antisocial) to-0.1 (narcissistic). In this population of patients, the SAP proved to be a poor screen for the SCID-II. The study highlights the discrepancy between informant and self-report assessments for personality disorder.

The assessment of personality disorders assumes unquestioned clinical relevance when considering the prevalence rates in the general population. Tests assessing the typical pathological traits of these disorders has been adapted to and developed in Brazil. However, there is a gap in the country of screening tools for personality disorders. Screening tools are designed to allow a fast and informative application on the likelihood of a positive diagnosis, where the consequence should be conveyed to a diagnostic assessment. Using as a base the Dimensional Clinical Personality Inventory (IDCP), developed at the national level, the objective of this research was to develop a screening tool for personality disorders, as well as investigate its diagnostic accuracy. The study included 1,196 people, aging between 18 and 73 years (M = 26.32, SD = 8.69), and 64.1% female. The sample was divided into clinical and non-clinical group. We used an empirical approach based on criteria for selection of items similar to those adopted in the development of Minnesota Multiphasic Personality Inventory was used (MMPI). The logistic regression analysis and also the calculation of Cohen´s d indicated the items that best discriminate against people with personality disorders and those without this diagnosis. We achieved a final set of 15 items with satisfactory sensitivity and specificity for screening test. We discusses the strengths and limitations of screening version of the IDCP and guidelines for further study.
