Alternative Hypotheses

Paranoid and schizoid personality disorders are not currently proposed to be in the DSM-5 despite a long history in the clinical lexicon. This chapter reviews theoretical and empirical research on these conditions in this context. Several alternative hypotheses to the view that these constructs reflect valid syndromes are described. It is concluded that the validity of paranoid and schizoid personality disorders as unique constructs cannot be determined based on existing research and that further investigation is needed to determine their nosological status. Eliminating paranoid and schizoid as unique personality disorders in the DSM-5 would be consistent with existing evidence and the availability of multiple viable alternatives to syndromal hypotheses about paranoid and schizoid behavior.

Prevention And Treatment

This article proposes a reflection on the possible causes and diagnosis of people involved in violent shootings. The policies for prevention of those social tragedies remain somewhat controversial and vaguely addressed, lacking theoretical attention (Rocque & Duwe, 2018). One of the main diagnoses involved in those cases, according to literature, is Schizoid Personality Disorder-SPD with characteristics of detachment, isolation and difficulties of contact with other human beings (DSM-5, 2013). The loss of capacity to establish social relationships and intimacy hamper and may sometimes impede a psychological treatment based on connection possibilities. Juvenile violence statistics increased dramatically in the last 50 years and because of this, early diagnosis is important for the prevention and treatment of these cases. At the same time, further research and case studies are a pressing need (Rocque, 2017). For diagnosed SPD patients, Bioenergetics Analysis stands out in a scenario in which rapprochement and contact are a priority, also as an approach that is open to new care techniques and alternatives investigations in helping people to open their hearts to life and love. If this objective is not achieved, the outcome, according to Lowen (1991) is tragic.

Abstract Background: The aim of this study was to investigate the psychometric properties of the Persian version of a structured clinical interview for personality disorders based on DSM-5 (R) (SCID-5-PD) in the population of patients with psychiatric disorders in Tehran.Method: The study population includes all outpatients and inpatients referred to three psychiatric centers in Tehran, including Iran Psychiatric Hospital, Rasoul Akram Hospital and Clinic of Behavioral Sciences and Mental Health (Tehran Psychiatric Institute). Inclusion criteria were age between 16 and 70 years, written Informed consent and the ability to understand and speak in Persian and no special physical problems that interfere with the interview process. Sampling in this study was done by Convenience sampling. In this study, in addition to the demographic questionnaire, the Persian version of SCID-5-PD was used. Finally, in order to evaluate the information, the methods of face and content validity and diagnostic validity, test-retest reliability and inter-rater reliability were used.Results: the diagnoses related to obsessive-compulsive personality disorder, paranoid, schizotypal, schizoid, histrionic, narcissistic, borderline and antisocial kappa were higher than 0.4 and the diagnoses related to avoidant personality disorder were dependent and in other certain disorders are below 0.4. Regarding borderline personality disorder with kappa 0.839, the highest agreement was reported between the two reports of the psychiatrist and the SCID interviewer. Also, the specificity results were mostly better than the sensitivity results, and in all diagnoses except obsessive-compulsive and paranoid personality disorder, the specificity was higher than 0.9 and in these two diagnoses, the specificity was higher than 0.85, which indicates the desired characteristic. SCID-5-PD. The sensitivity of all diagnoses except avoidant and dependent personality disorder was also reported to be higher than 0.8; But the susceptibility of avoidant and dependent personality disorder was 0.66. Also, the study of LR + / LR- ratio showed that this tool has the best diagnosis for histrionic, antisocial and schizotypal personality disorder. It is also suitable for other personality disorders except schizoid personality disorder and certain other disorders.Conclusion: According to the findings of the present study, SCID-5-PD can be used in psychiatric clinics and hospitals as a diagnostic tool. In general, this version is suitable for most diagnoses; but with regard to diagnoses of schizoid personality disorder and certain other disorders, this should be done with more caution.

Axis I

An alternative diagnostic model of personality disorders (AMPD) was introduced in DSM-5 that diagnoses PDs based on the presence of personality impairment (Criterion A) and pathological personality traits (Criterion B). Research examining Criterion A has been limited to date, due to the lack of a specific measure to assess it; this changed, however, with the recent publication of a self-report assessment of personality dysfunction as defined by Criterion A (Levels of Personality Functioning Scale – Self-report; LPFS-SR; Morey, 2017). The aim of the current study was to test several key propositions regarding the role of Criterion A in the AMPD including the underlying factor structure of the LPFS-SR, the discriminant validity of the hypothesized factors, whether Criterion A distinguishes personality psychopathology from Axis I symptoms, the overlap between Criterion A and B, and the incremental predictive utility of Criterion A and B in the statistical prediction of traditional PD symptom counts. Neither a single factor model nor an a priori four-factor model of dysfunction fit the data well. The LPFS-SR dimensions were highly interrelated and manifested little evidence of discriminant validity. In addition, the impairment dimensions manifested robust correlations with measures of both Axis I and II constructs, challenging the notion that personality dysfunction is unique to PDs. Finally, multivariate regression analyses suggested that the traits account for substantially more unique variance in DSM-5 Section II PDs than does personality impairment. These results provide important information as to the functioning of the two main components of the DSM-5 AMPD and raise questions about whether the model may need revision moving forward.Keywords: dysfunction, impairment, personality disorders, Section III, incremental validity Public Significance: The alternative model of personality disorders included in Section III of the 5th addition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes two primary components: personality dysfunction and maladaptive traits. The current results raise questions about how a new, DSM-5 aligned measure of personality dysfunction operates with regard its factor structure, discriminant validity, ability to differentiate between personality and non-personality based forms of psychopathology, and incremental validity in the statistical prediction of traditional DSM personality disorders.

Abstract Background: The Personality Inventory for DSM-5 Brief Form (PID-5-BF) is a 25-item measuring tool evaluating maladaptive personality traits for the diagnosis of personality disorders(PDs). As a promising scale, its impressive psychometric properties have been verified in some countries, however, there have no studies about the utility of PID-5-BF in Chinese settings. The current study aimed to explore the maladaptive personality factor model which was culturally adapted in China and examine psychometric properties of the Personality Inventory for DSM-5 Brief Form among Chinese undergraduate students and clinical patients.Methods: 7155 undergraduate students and 451 clinical patients completed the Chinese version of PID-5-BF. 228 students were chosen randomly for test-retest reliability at a 4-week interval. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to discover the most suitable construct in Chinese, measurement invariance(MI), internal consistency, and external validity were also calculated.Results: An exploratory six-factor model was supported more suitable in both samples(Undergraduate sample: CFI = 0.905, TLI = 0.888, RMSEA = 0.044, SRMR = 0.039; Clinical sample: CFI = 0.904, TLI = 0.886, RMSEA = 0.047, SRMR = 0.060), adding a new factor“Interpersonal Relationships”. Measurement invariance across non-clinical and clinical sample was established (configural, weak, strong MI, and partial strict MI). Aside from acceptable internal consistency (Undergraduate sample: alpha=0.84, MIC=0.21; Clinical sample: alpha=0.86, MIC=0.19) and test-retest reliability(0.73), the association with 220-item PID-5 was significant(r = 0.93, p < 0.01), and six PDs measured by Personality diagnostic questionnaire-4+ (PDQ-4+) were correlated with expected domains of PID-5-BF.Conclusions: The PID-5-BF is a convenient and useful screening tool for personality disorders with a novel six-factor model in Chinese settings, with the main difference for the Negative Affect domain.

The recently published DSM-5 included a dimensional model of personality pathology, which includes pathological traits. This model is a response to the many criticisms and problems documented with the traditional categorical modal of personality disorders. To date, numerous studies have demonstrated that the trait model is more valid and reliable than the traditional categorical model (Krueger and Markon 2013). This study expands research on the trait model by assessing the association between the DSM-5 traits and propensity for, or attitudes about, violence.
