“…The meta-analyses by Mihura et al (2013) found that the PTI had one of the highest validity coefficients of all Rorschach CS variables (r = .39) as an indicator of disturbed thinking and distorted perception. A recent study found that the PTI is unaffected by antipsychotic medication in a sample of 114 psychotic patients (Biagiarelli et al, 2017), which again suggests the PTI measures the underlying perceptual and thought processes, and not the symptoms of psychosis. Rorschach responses of patients with schizophrenia could be successfully simulated using a neural network model, which proposed lack of context integration, caused by an altered noise-to-signal ratio at the level of the single neuron, as the cause of distorted perception and thinking on the Rorschach (Peled & Geva, 2000).…”

“…Before Exner's Comprehensive System (CS) became the dominant coding and interpretation system in many countries (Exner, 2003), several scholars had developed criteria for coding aggression in Rorschach responses. Examples are Elizur's Hostility Scale and Holt's Primary (A1) and Secondary Process (A2) Aggression (Elizur, 1949;Holt, 1977). Exner did not include aggressive content codes in the CS, but only included a code for aggressive movement (AG, now AGM in the R-PAS system).…”

Abstract. Over the years, a significant number of Rorschach studies have been conducted with forensic adult and adolescent samples, partly motivated by the use of the test in forensic psychological evaluations. Could the Rorschach, as a performance-based personality assessment tool, provide unique information that is not as vulnerable to distortion on the part of the examinee as self-report measures are? This article provides a review of Rorschach studies on relevant Rorschach variables, including those with different forensic samples. Empirical findings are mixed; there is not a one-on-one relationship between certain Rorschach variables and forensically relevant traits, such as psychopathy or hostility. This does not mean the Rorschach cannot provide useful information in answering psychological questions before the court. A case illustration of a male college student, who committed a (first) violent offense, illustrates the unique contribution of the Rorschach for understanding the psychological dynamics behind a violent act that was seemingly out of character.

“…A systematic review and meta-analysis shows that disordered thinking can be as elevated for persons experiencing a manic episode as it is for persons diagnosed with schizophrenia (Yalincetin et al, 2017). R-PAS contains six types of variables called Cognitive Codes that are well-validated to assess disordered thinking (Biagiarelli et al, 2015;Eblin et al, 2018;Mihura et al, 2013) Bipolar, Mania Versus Schizophrenia. The previous meta-analysis by Yalincetin et al (2017) that found disorganized thinking equally elevated for patients with mania and those with schizophrenia included a clinical interview and Rorschach-based measures.…”

T his chapter provides guidance on using the Rorschach Performance Assessment System (R-PAS; Meyer et al., 2011) in the assessment of bipolar disorders. It is important to note that neither R-PAS nor self-report questionnaires are designed to make formal Diagnostic and Statistical Manual of Mental Disorders (DSM) or International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses. However, as described in what follows, R-PAS data can aid diagnosis by informing the decision process in a multimethod assessment.

“…With respect to its interpretive significance, a PTI positive for three of these five criteria begins to suggest difficulties in thinking logically and perceiving the world accurately, and the presence more than three is likely to identify an extent of cognitive dysfunction associated with schizophrenia spectrum or other psychotic disorders (Benedik et al, 2013;Biagiarelli et al, 2017;Dao & Prevatt, 2006;Hilsenroth et al, 2007). As shown in Table 8.1, a PTI > 3 rarely occurs in nonpatient adults (2%), adolescents (1%), and senior adults (3%).…”

T he Rorschach is a multifaceted personality assessment measure that consists of 10 inkblots printed individually on 6-inch by 9-inch cards. Five of the blots are in shades of gray and black; two of the blots are in shades of red, gray, and black; and the remaining three blots are in shades of pastel colors. Respondents are shown the 10 blots one at a time and asked, "What might this be?" If they have difficulty answering, they are asked further, "What does it look like to you?" or "What do you see in it?" In a follow-up inquiry, respondents are asked where in the blots they saw each of their percepts and what made it look as it did. Responses are then coded for their Location, Determinants, Content, and a variety of special scores, which taken together provide information about a person's cognitive functioning, affective experience, interpersonal relatedness, and self-perception. These basic aspects of Rorschach coding and interpretation have been elaborated by Choca ( 2013), Choca and Rossini (2018), Sciara et al. (2014), and Weiner (2013b.The Rorschach Comprehensive System (RCS) emerged from the work of Hermann Rorschach, a Swiss psychiatrist who, in 1917, began to examine what people with various personality characteristics would report seeing in a series of inkblots in a variety of shapes and colors. From the responses of 288 mental hospital patients and 117 nonpatients, Rorschach selected the previously mentioned 10 blots on the basis of their eliciting particularly interesting responses. His work with these blots culminated in the 1921 publication of Psychodiagnostics: A Diagnostic Test Based on Perception (Rorschach, 1942),
