Insight Into

Individuals with obsessive-compulsive disorder (OCD) often have good insight into the irrational nature of their obsessions and the excessive character of their compulsions, but insight exists along a continuum and is markedly poor in some patients. This chapter reviews the assessment and phenomenological correlates of variable insight in OCD in both pediatric and adult populations. It reviews the definition of insight and its relationship to the evolution of diagnostic criteria for obsessive-compulsive disorder, as well as the major assessment tools used to measure and quantify insight for clinical and research purposes. The relationships between insight and clinical characteristics of OCD, including symptom severity, comorbidity, and treatment response are reviewed, followed by a review of neurobiological correlates of insight and the relationship between poor insight and schizophrenia spectrum disorders.

SYNOPSISThree monozygotic twin pairs are described who are concordant for DSM-III-R obsessive-compulsive disorder while being discordant for schizophrenia or schizoaffiective disorder. Follow-up interview showed the non-psychotic co-twins to have schizotypal personality disorder. It is concluded that obsessive-compulsive and schizophrenia-spectrum disorders can truly co-exits, thus supporting diagnostic changes introduced into DSM-III-R, and may in some cases be inherited together.

Abstract The differential diagnosis of obsessive–compulsive disorder (OCD) and schizophrenia-spectrum disorders can be difficult. In the current diagnostic criteria, basic concepts such as obsession and delusion overlap. This study examined lifetime schizophrenia-spectrum psychopathology, including subtle schizotypal symptomatology and subjective anomalies such as self-disorders, in a sample diagnosed with OCD in a specialized setting. The study also examined the differential diagnostic potential of the classic psychopathological notions of true obsession (‘with resistance’) and pseudo-obsession. The study involved 42 outpatients diagnosed with OCD at two clinics specialized in the treatment of OCD. The patients underwent semi-structured, narrative interviews assessing a comprehensive battery of psychopathological instruments. The final lifetime research-diagnosis was based on a consensus between a senior clinical psychiatrist and an experienced research clinician. The study found that 29% of the patients fulfilled criteria of schizophrenia or another non-affective psychosis as main, lifetime DSM-5 research-diagnosis. Another 33% received a research-diagnosis of schizotypal personality disorder, 10% a research-diagnosis of major depression and 29% a main research-diagnosis of OCD. Self-disorders aggregated in the schizophrenia-spectrum groups. True obsessions had a specificity of 93% and a sensitivity of 58% for a main diagnosis of OCD. In conclusion, a high proportion of clinically diagnosed OCD patients fulfilled diagnostic criteria of a schizophrenia-spectrum disorder. The conspicuous obsessive–compulsive symptomatology may have resulted in a disregard of psychotic symptoms and other psychopathology. Furthermore, the differentiation of obsessions from related psychopathological phenomena is insufficient and a conceptual and empirical effort in this domain is required in the future.

AbstractAlthough obsessive-compulsive disorder (OCD) is classified as an anxiety disorder in the DSM-IV, recent considerations for a reclassification into an obsessive-compulsive spectrum disorders (OCSDs) cluster are gaining prominence. Similarities in symptomatology, course of illness, patient population, and neurocircuitry of OCD and OCSD are supported by comorbidity, family, and neurological studies, which also offer a critical re-evaluation of the relationship between OCD and anxiety disorders. This review examines potential classifications of OCD among the wider spectrum of affective disorders and at the interface between affective disorders and addiction. In addition, it has been suggested that the categorical diagnostic approach would be enhanced by an additional dimensional approach, including parameters such as stability of mood and ability to sustain attention. With further studies, it is ultimately the goal to define OCD and related disorders based on endophenotypes.Despite efforts in this field, there are several fundamental unresolved issues, including the question of which disorders should be grouped together in this category and which characteristics to include as their shared common features. A reclassification of OCD among the OCSDs would allow for better scrutiny of distinct obsessive-compulsive symptoms, as currently this disorder often goes undetected in patients who complain of a broad symptom of anxiety. Advantages and disadvantages of establishing OCSDs and its implications for diagnosis, treatment, and research are discussed.

Abstract Obsessive–compulsive disorder (OCD) is a chronic and disabling mental disorder characterized by the presence of obsessions and/or compulsions that cause major distress and impair important areas of functioning. About 9 out of 10 patients with OCD have comorbid psychiatric diagnoses. A high proportion of clinically diagnosed OCD patients fulfill diagnostic criteria of a schizophrenia spectrum disorder, to the point that significant evidence in the literature supports the existence and the clinical relevance of a schizo-obsessive spectrum of disorders, including schizotypal personality disorder (SPD) with OCD (schizotypal OCD). In this paper, we provide a brief but comprehensive analysis of the literature on the clinical coexistence between OCD and SPD. The clinical validity of the so-called schizotypal OCD is analyzed through a comprehensive investigation of the relationship between SPD features and obsessive–compulsive phenomena in clinical OCD samples. This review describes the potential connections between OCD and SPD on the epidemiological, sociodemographic, psychopathological, and clinical levels. SPD is commonly observed in OCD patients: about 10% of OCD patients have a full categorical diagnosis of SPD. Early clinical identification of SPD features—and, more generally, of psychotic features and personality disorders—in OCD patients is strongly recommended. In fact, a proper and early diagnosis with early treatment may have benefits for prognosis. However, although schizotypal OCD seems to have clinical and predictive validity, further neurobiological and genetic studies on etiological specificity are warranted.

Abstract. The Structured Interview for Hoarding Disorder (SIHD) is a semi-structured interview designed to assist clinicians in diagnosing a hoarding disorder (HD). This study aimed to validate the Italian version of the SIHD. For this purpose, its inter-rater reliability has been analyzed as well as its ability to differentiate HD from other disorders often comorbid. The sample was composed of 74 inpatients who had been diagnosed within their clinical environment: 9 with HD, 11 with obsessive-compulsive disorder (OCD) and HD, 22 with OCD, 19 with major depressive disorder (MDD), and 13 with schizophrenia spectrum disorders (SSD). The results obtained indicated “substantial” or “perfect” inter-rater reliability for all the core HD criteria, HD diagnosis, and specifiers. The SIHD differentiated between subjects suffering from and not suffering from a HD. Finally, the results indicated “good” convergent validity and high scores were shown in terms of both sensitivity and specificity for HD diagnosis. Altogether, the SIHD represents a useful instrument for evaluating the presence of HD and is a helpful tool for the clinician during the diagnostic process.
