Le TP, Ventura J, Subotnik KL, Nuechterlein KH. Intrinsic motivation predicts cognitive and functional gains during coordinated specialty care for first-episode schizophrenia. Schizophr Res 2024; 266:249-255. [PMID: 38442522 DOI: 10.1016/j.schres.2024.02.037] [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: 08/23/2023] [Revised: 01/01/2024] [Accepted: 02/26/2024] [Indexed: 03/07/2024]
Abstract
Coordinated Specialty Care (CSC) and embedded group therapeutic interventions have been effective in improving outcomes for individuals experiencing recent first-episode schizophrenia, including cognitive performance and functioning. Treatment response varies substantially, with some patients experiencing limited or no improvement. Motivation has emerged as a key determinant of treatment engagement and efficacy. However, the impact of intrinsic and extrinsic aspects of motivation has not been directly examined with treatment outcomes in first-episode schizophrenia. This study investigated whether baseline levels of intrinsic and extrinsic motivation predicted cognitive and functional gains over 6 and 12 months in CSC. Forty participants with first-episode schizophrenia completed a 12-month CSC treatment period. Baseline measures of intrinsic and extrinsic motivation were obtained for group therapeutic interventions and work/school, as well as measures of cognition and functioning (role and social) at baseline, 6 months, and 12 months. Results revealed that higher baseline scores of intrinsic motivation for group therapeutic interventions were significantly predictive of greater cognitive gains at 12 months, and a similar tendency was observed at 6 months. Additionally, baseline scores of intrinsic motivation for work/school predicted role gains at 6 months, with a similar tendency observed at 12 months. Extrinsic motivation did not consistently impact treatment outcomes, except for work/school-related extrinsic motivation, which was linked to greater social functioning gains at 12 months. These findings provide insight into the factors influencing treatment outcomes for individuals with first-episode schizophrenia and highlight the importance of intrinsic motivation as a modifiable personal variable that can enhance response to CSC.

Abstract
Cognitive impairment associated with schizophrenia (CIAS) is widely regarded as a critically important treatment target for schizophrenia. Despite major efforts and a number of promising findings, we do not yet have an approved drug for CIAS. Similarly, promising cognitive remediation approaches are limited in their ability to help patients achieve real-world functional gains on a wide scale. This article provides an update and critical evaluation of recent treatment development activities for CIAS. First, we provide update on pharmacological approaches, which include a glutamatergic drug that is currently in Phase III trials for CIAS, and discuss factors that may have impacted past efforts to identify efficacious drugs. Second, we review positive findings, limitations, and current trends involving cognitive remediation approaches. Third, we consider newer transdiagnostic approaches aimed at looking beyond, or identifying more homogenous subgroups within, the diagnostic category schizophrenia to advance treatment development. Despite its many challenges, treatment development for CIAS remains a major public health issue and research continues to push forward on several encouraging fronts.

Abstract
Women present a second peak of incidence of psychosis during the menopausal transition, partially explained by the loss of estrogen protection conferred during the reproductive years. In view of the lack of studies comparing sociodemographic, biological, and clinical variables and neurocognitive performance between women with early onset of psychosis (EOP) and those with late onset of psychosis (LOP), our aim was to characterize both groups in a large sample of 294 first-episode psychosis (FEP) patients and 85 healthy controls (HC). In this cross-sectional study, the participants were interviewed to gather information on sociodemographic variables. We assessed laboratory features of interest and conducted a clinical assessment of psychopathological symptoms and neurocognitive abilities. From the latter, we derived a global cognitive functioning score. Analysis of covariance (ANCOVA) was used to compare EOP and LOP groups, and each group with age-comparable HC. EOP women were more frequently single and unemployed than HC age peers. While cholesterol levels in LOP women were higher than those in EOP women, no statistically significant differences were found in leptin levels. Women with LOP presented with less severe negative symptoms and higher cognitive processing speed scores than women with EOP. Cannabis and alcohol use was greater in EOP than in LOP women. Within the total FEP group, there was a history of significantly more recent traumatic events than in the HC group. Women with EOP and LOP show several sociodemographic and clinical differences, which may be valuable for planning personalized treatment.
