An Examination of Interrater Reliability for Scoring the Rorschach Comprehensive System in Eight Data Sets

In this article, we describe interrater reliability for the Comprehensive System (CS; Exner, 1993) in 8 relatively large samples, including (a) students, (b) experienced researchers, (c) clinicians, (d) clinicians and then researchers, (e) a composite clinical sample (i.e., a to d), and 3 samples in which randomly generated erroneous scores were substituted for (f) 10%, (g) 20%, or (h) 30% of the original responses. Across samples, 133 to 143 statistically stable CS scores had excellent reliability, with median intraclass correlations of .85, .96, .97, .95, .93, .95, .89, and .82, respectively. We also demonstrate reliability findings from this study closely match the results derived from a synthesis of prior research, CS summary scores are more reliable than scores assigned to individual responses, small samples are more likely to generate unstable and lower reliability estimates, and Meyers (1997a) procedures for estimating response segment reliability were accurate. The CS can be scored reliably, but because scoring is the result of coder skills clinicians must conscientiously monitor their accuracy.

The Self Focus Sentence Completion: A Study of Egocentricity

Summary A 30-item sentence completion blank (SFSC), in which most of the stems contain a self-reference (I, my, me, etc.) is described. Normative data are provided for 2,592 non-psychiatric subjects representing five different kinds of populations, and 273 psychiatric patients from nine different diagnostic groups. Reliability data are presented and the results of six validation studies are discussed. It is suggested that the SFSC, which yields six scores, may provide a useful index of egocentricity as a response orientation or style. The data are discussed in the context of “egocentric balance,” a postulate seemingly compatible with several theoretical positions.

Superiority of Form% Over Lambda for Research on the Rorschach Comprehensive System

Lambda is an important variable in the Rorschach Comprehensive System. However, because of the way it is calculated it has properties that can produce problems for parametric statistical analyses. We illustrate these difficulties and encourage the use of Form% (i.e., pure form responses/total responses) instead of Lambda in research. Form% is easy to calculate, and it is conceptually and mathematically comparable to Lambda. Because it is much more normally distributed, Form% is suitable to use in parametric analyses (e.g., t tests, analyses of variance, correlations, factor analyses, multiple regressions).

A New Nonpatient Sample for the Rorschach Comprehensive System: A Progress Report

Some concern about recently published nonpatient data, plus the fact that some records in the published sample of 600 nonpatients (Exner, 2001) were collected more than 20 years ago, prompted the initiation of a project to develop a new nonpatient sample. In this article, findings are presented for the first 175 participants tested in the new project. It is noted that the data from the new project are quite similar to those for the sample of 600. Results suggest that the similarities between the data sets supports the notion that the published sample is probably representative and provides a reasonable basis from which to identify response rates and the proportions of nonpatients expected to fall in, or outside of, established parameters for various ratios and other structural indexes.

Modifying the Rorschach Human Experience Variable to create the Human Representational Variable.

The Human Experience Variable (HEV; Perry & Viglione, 1991) provided information about interpersonal perceptions not previously available within the Comprehensive System (CS; Exner, 1993). Research data suggests that it was related to interpersonal functioning and as a result, psychological impairment and health. In this article, we present the rationale and empirical basis for recent psychometric refinements to the HEV, consequently renamed the Human Representational Variable (HRV). Research addressing the reliability and validity for the HRV is summarized. Based on data and experience with the HEV, this study summarized some small modifications to the original algorithm. The refined variable, the HRV, has been added to the CS (Exner, 2000). Data presented here suggest that the HRV has improved psychometric properties compared to the HEV and that it is simpler to understand. Research recommendations and interpretive suggestions are also presented.

A New U.S. Adult Nonpatient Sample

A project to collect an American adult nonpatient sample for the Rorschach Comprehensive System (CS; Exner, 2001) took place between 1999 and 2005, and this article presents data for 450 participants in the project. Inclusion criteria, demographic information, and interrater agreement statistics are described. Findings for most of the CS variables are similar to earlier Rorschach Workshops samples, but some differences emerged and their implications for modifying interpretive guidelines are discussed.
