In this article, we describe interrater reliability for the Comprehensive System (CS; Exner. 1993) in 8 relatively large samples, including (a) students, (b) experienced re- searchers, (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 Meyer's (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.

of the forthcoming book Self-Organizing Complexity in Psychological Systems.I wish to acknowledge my deep appreciation to Emmanuel Ghent for his years of encouragement, warmth, and incisive, constructive feedback. He was a great mentor, colleague, and friend. He is truly missed.The article opens with a fairly detailed overview of the research on nonlinear dynamic systems, deterministic chaos, and complexity theory-referred to collectively as complexity theory. The second part of the article is aimed at applying this research to an interesting discussion that has developed in the psychoanalytic literature regarding the fundamental nature of the self as either singular or multiple. Chaotic systems (a class of nonlinear systems) exhibit staggering variability, sensitivity, and adaptation in response to perturbation (in the form of sensitive dependence on initial conditions), while also demonstrating an enduring and distinctive coherence and continuity in their overall organization (in the form of strange attractors). As such, chaotic systems are useful in conceptualizing how relatively healthy people remain recognizable (or in character) in the midst of their variability, multiplicity, and change. By contrast, pathology of the self from the perspective of nonlinear dynamic systems is characterized by the repetitive, periodic and self-same quality of mental states. HIS ARTICLE OPENS WITH A FAIRLY DETAILED OVERVIEW OF THEresearch on nonlinear dynamic systems, deterministic chaos, Tand complexity theory-which I refer to collectively as complexity theory. The second part of the article is aimed at applying this research to an interesting discussion that has emerged in the psychoanalytic literature regarding the fundamental nature of the self.

In this article we examine the relation between the Rorschach Comprehensive System's Suicide Constellation (S-CON;Exner, 1993;Exner & Wiley, 1977) and lethality of suicide attempts during the course of patients' hospitalization at the Austen Riggs Center (Stockbridge, MA). Patient records were rated as nonsuicidal (n = 37), parasuicidal (n = 37), or near-lethal (n = 30) based on the presence and lethality of self-destructive acts. Diagnostic efficiency statistics utilizing a cutoff score of 7 or more positive indicators successfully predicted which patients would engage in nearlethal suicidal activity relative to parasuicidal patients (overall correct classification rate [OCC] = .79), nonsuicidal inpatients (OCC = .79), and college students (OCC = .89). Although these predictions were influenced by relatively high base rates in the hospital population (14.5%), base rate estimates were calculated for other hypothetical populations revealing different prediction estimates that should be considered when judging the relative efficacy of the S-CON. Logistic regression analysis revealed that an S-CON score of 7 or more was the sole predictor of near-lethal suicide attempts among 9 psychiatric and demographic variables.

Aspects of unconscious processes in a group of seriously disturbed psychiatric patients are examined in an effort to predict near-lethal suicide attempts and explore psychoanalytic formulations of suicide. The Rorschach Inkblot Test, the most widely used projective measure in suicide research (Bongar 1991), was chosen for its potential to shed light on specific unconscious processes. Psychic states commonly associated with suicide were measured by psychoanalytic Rorschach analog scales and then subjected to a progression of statistical analyses in order to predict future occurrence and lethality of suicide attempts. On the basis of a priori hypotheses, the authors developed a suicide index comprising four psychoanalytic Rorschach signs that predicted, with considerable accuracy, which patients would later make near-lethal suicide attempts. The best predictors were unconscious processes indicative of penetrating affective overstimulation, disturbance in the capacity to maintain adequate ego boundaries, and depressive affective states characterized by a morbid preoccupation with death and inner decay. These findings provide empirical support for several well-known formulations of the unconscious motivations for suicide.
