Maladaptive personality traits in patients with recent-onset psychosis: A case-control study using the Personality Inventory for the DSM-5 (PID-5). Schizophr Res 2023; 252:216-224. [PMID: 36669345 DOI: 10.1016/j.schres.2023.01.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 07/05/2022] [Accepted: 01/07/2023] [Indexed: 01/19/2023]
Abstract
BACKGROUND The relationship between maladaptive personality traits and psychotic disorders in the early stages of disease has not been thoroughly investigated, even though it is essential for developing prevention and early intervention strategies. METHODS The five domains and the 25 facets of the Personality Inventory for DSM-5 (PID-5) were compared between 102 patients with recent-onset psychosis (ROP) and 116 community subjects (C) with a general linear model including age and sex in the analyses. In addition, multiple linear regression models were used to identify which factors associated with the PID-5 domains in ROP, and correlation analyses were used to explore the relationship between personality traits. RESULTS Patients with ROP, compared to C, exhibited higher scores in four out of the five domains with medium effect sizes (Cohen's f2 ≥ 0.15) in two of them: negative affect (NA, p = 0.013, f2 = 0.04), detachment (DET, p < 0.001, f2 = 0.15), disinhibition (DIS, p < 0.001, f2 = 0.14) and psychoticism (PSY, p < 0.001, f2 = 0.16). Significant group differences were observed in 15 of the 25 facets and the largest effects were observed in the facets of withdrawal (p ≤ 0.001, f2 = 0.20), irresponsibility (p < 0.001, f2 = 0.23) and unusual beliefs (p = 0.001, f2 = 0.22). Interestingly, being on antidepressants and high scores on the positive subscale of the Positive and Negative Syndrome Scale (PANSS) were associated with high scores of NA, antagonism (ANT) and PSY. CONCLUSIONS Maladaptive personality traits were prominent in persons with ROP. These findings suggest that personality traits might play a role in vulnerability to psychosis and highlight the importance of evaluating personality in the early stages of psychosis.

Abstract
An integrated and interdisciplinary care system for individuals with schizophrenia is essential, which implies the need for a tool that assesses the difficulties and contextual factors of relevance to their functioning, and facilitates coordinated working across the different professions involved in their care. The International Classification of Functioning, Disability and Health Core Sets (ICF-CS) cover these requirements. This study aimed to evaluate the content validity of the ICF-CSs for schizophrenia from the perspective of experts. Six three-round Delphi studies were conducted with expert panels from different professional backgrounds which have played a significant role in the treatment of individuals with schizophrenia (psychiatry, psychology, nursing, occupational therapy, social work and physiotherapy). In total, 790 experts from 85 different countries participated in the first round. In total, 90 ICF categories and 28 Personal factors reached expert consensus (reached consensus from four or more professional perspectives). All the categories in the brief version of the ICF-CS for schizophrenia reached consensus from all the professional perspectives considered. As for the comprehensive version, 89.7% of its categories reached expert consensus. The results support the worldwide content validity of the ICF-CSs for schizophrenia from an expert perspective and underline the importance of assessing functioning by considering all the components implied.

Abstract
Schizophrenia is a severe mental disorder associated with impairment in functioning. A multidisciplinary approach is essential to help individuals with this health condition, and psychological interventions are considered a priority. The International Classification of Functioning, Disability and Health (ICF) offers a theoretical framework for assessing functioning and disability. The ICF Core Sets for schizophrenia are a list of ICF categories describing the most common problems in functioning of persons affected by this health condition. This study aimed to explore the content validity of these ICF Core Sets and to identify the most common problems in people with schizophrenia from the perspective of psychologists. Psychologists with experience of schizophrenia treatment were recruited for a three-round Delphi study in order to gather their views regarding the problems commonly presented by these patients. A total of 175 psychologists from 46 countries covering the six WHO regions answered the first-round questionnaire, and 137 completed all three rounds. The 7,526 concepts extracted from first-round responses were linked to 412 ICF categories and 53 personal factors. Consensus (≥75% agreement) was reached for 76 ICF categories and 28 personal factors. Seventy-three of the 97 ICF categories that form the Comprehensive ICF Core Set for schizophrenia achieved consensus, and only three categories that yielded consensus do not feature in this Core Set. These results support the content validity of these ICF Core Sets from the perspective of psychologists. This provides further evidence of the suitability of the ICF framework for describing functioning and disability in persons with schizophrenia.
