“…It is natural for the ratio of under-estimator to over-estimator to change with sampling. Furthermore, previous studies have reported that higher levels of daily living function and higher cognitive abilities are associated with overestimation of their own cognitive impairments [ 32 ]. The participants in this study were outpatients with stable clinical status, and most of them achieved all categories of the WCST.…”

Premorbid intellectual ability in schizophrenia influence family appraisal related to cognitive impairments: a cross-sectional study on cognitive impairment and family assessments

Background Patients with schizophrenia are unaware of their cognitive impairments. Misperception of cognitive impairment is an important factor associated with real-world functional outcomes in patients with schizophrenia. The patient’s family member plays a crucial role in detecting patients’ cognitive impairments when the patients are unaware of their own cognitive impairments. Previous studies have reported that not only the patient’s subjective rating, but also the patient’s family members’ rating of their cognitive impairment may not be precise. However, it is unclear why family ratings are inaccurate, and which factors impact family ratings. This study investigated whether family ratings differed significantly from the patients’ subjective ratings of the patients’ cognitive impairments and sought to determine the reason for the differences between the family ratings and the patients’ neurocognitive performances. We investigated the relationship between patients’ subjective ratings, family ratings for patients’ cognitive impairments, neuropsychological performance, and other aspects, including premorbid IQ and clinical symptoms. Method We evaluated 44 patients with schizophrenia for cognitive function using neuropsychological tests; in addition, both the patients and their families rated the patients’ cognitive impairments through questionnaires. We used the Mann–Whitney U test to examine whether the family ratings differed significantly from the patients’ self-reported ratings of their cognitive impairment. We conducted multiple regression analysis and structural equation modeling to determine why the patients’ subjective ratings and the family ratings were not definitively associated with the patients’ neurocognitive performances. We performed multiple regression analysis with a stepwise method with neurocognitive performance, premorbid IQ, positive symptoms, and negative symptoms as independent variables and family ratings of patients’ cognitive impairments as dependent variables. Results We found that the family ratings differed significantly from the patients’ subjective self-reported ratings of their cognitive impairments. Our results showed that the premorbid IQ of patients is the strongest predictor of family ratings. Furthermore, among the neurocognitive domains, only the processing speed of patients was associated with family ratings. Conclusions We found that the family ratings were not consistent with the patients’ subjective self-reported ratings and the family ratings were most affected by the patients’ premorbid intellectual abilities. These results suggest that the families’ current assessments of the patients’ current cognitive impairments were affected by the patients’ premorbid intellectual ability rather than the patients’ current neurocognitive performance. Patients’ processing speed predicted family ratings; however, family members' ratings were not related to verbal learning/memory, executive function, and language of patients. Therefore, our findings highlight that patients’ family ratings may differ from patients’ subjective ratings, results of performance-based neuropsychological tests, and clinician ratings.

“…CBT therapy brought several impacts, such as cognitive distortions, disturbing feelings to emotions without causing loss of self-awareness, social problems, and physiological problems. Kim et al (2020) explain that patients' inability to recognize maladaptive thoughts and behaviors contributes significantly to the emergence of positive symptoms [12]. This condition disables them to find adaptive coping to deal with the situation experienced.…”

“…It causes the inability to solve problems and perform social-cognitive actions [10]. This condition makes patients with schizophrenia act violently toward other people [8], [12]. They experience failure to manage their emotions when negative situations happen, and their expressions of emotion result in maladaptive action and lack empathy [13].…”

BACKGROUND: Schizophrenia is a condition in which people suffer from impaired ability to think, perceive, and show emotional responses and interact socially. Patients with schizophrenia can experience the risk of violent behavior (RVB). Psychotherapy is needed to deal with the problem. AIM: This study aimed to investigate the effects of cognitive behavior therapy (CBT) and social skill training (SST) on signs and symptoms of risks of violent behavior (RVB). METHODOLOGY: This study employed a quasi-experimental without a control group. The research samples used purposive sampling were 30 patients with symptoms of risks of violent behavior. Meanwhile, the measurement used the sign and symptom questioners of risks of violent behavior (Z = 0.791). RESULT: This study revealed that signs and symptoms decreased significantly (p < 0.05) from 10.45 to 5.41 after the respondents had obtained the CBT. Moreover, after the respondents had received CBT and SST, the sign and symptoms decreased significantly (p < 0.05) from 5.41 to 0.52. CONCLUSION: This study recommends that the combination of CBT and SST be administered to patients with schizophrenia with risks of violent behavior.

“…The patients were divided according to their self-assessment of their own abilities. The accuracy of the evaluation was assessed by comparing the patients’ self-reported score of function with an informant-reported score, using traditional self-assessment techniques of functional status ( Bowie et al, 2007 ) and recent studies ( Kim, Jung, et al, 2020 ). The self-reported score was evaluated by using the Social Functioning Scale (SFS) ( Birchwood et al, 1990 ), and the informant-reported score was evaluated using the Life Assessment Scale for Mental Illness (LASMI) ( Iwasaki et al, 1994 ), which is frequently used in Japan.…”

Background/Objectives People with schizophrenia have defective self-assessment of ability (i.e., loss of introspective accuracy [IA]). Although previous studies grouped people according to the degree of IA, the clinical features of these subgroups have not been clarified. Additionally, the determinants of outcomes depending on self-assessment remain unknown. We aimed to identify the clinical features that can help distinguish these subgroups and whether the determinants of vocational outcomes differed between the groups. Methods The self-assessment ability of 100 people with schizophrenia was examined and categorized as accurate, over-, or under-estimators. Multiple discriminant analysis was also performed. After demonstrating statistical validity, the relative effects of positive and negative symptoms, cognitive function, and level of IA on vocational outcomes were also examined for each subgroup. Results The symptoms that particularly explained the differences between these subgroups were positive and negative (expressing factors) symptoms: p < .001. Using the determinants of vocational outcomes in each subgroup, the over-estimator subgroup was characterized by positive symptoms: p = .025, the under-estimator group, by the underestimation of their own ability: p = .042, and the accurate estimator group, by cognitive function: p = .006. Conclusion Reduced IA can be a core mediator of various symptoms. Thus, tailoring the target and strategy of interventions for vocational outcomes according to the accuracy and quality of IA is important in clinical settings.
