Abstract
OBJECTIVE Cognitive impairment has a critical impact on functional outcomes in patients with schizophrenia. Compensatory cognitive training (CCT) has shown promise as a cognitive rehabilitation tool but little is known about its effectiveness when combined with medication self-management skills training (MSST) in patients with schizophrenia. Thus, this study compared the effects of a combined CCT and MSST with CCT and treatment as usual (TAU) on cognitive function, symptoms, and medication adherence. METHOD Eighty-seven inpatients with schizophrenia were randomly assigned to the TAU, CCT, or CCT + MSST groups. Assessments of cognitive function using the Brief Assessment of Cognition in Schizophrenia, symptoms using the Positive and Negative Syndrome Scale, and medication adherence using the Medication Adherence Questionnaire, were administered to all participants at baseline and at post-intervention. RESULTS Compared with the TAU group, the CCT group had significant improvements in verbal fluency, total cognitive function and medication adherence, and the CCT + MSST group had significant improvements in verbal fluency, total cognitive function, positive symptoms, and medication adherence. Compared with the CCT group, the CCT + MSST group had significant improvements in total cognitive function. CONCLUSIONS These results indicate that the integrated intervention may be more advantageous than CCT alone in improving total cognitive function and positive symptoms. Future research should seek to further explore the long-term effects of such a joint intervention.

Insight, personality, and symptoms among individuals with psychosis: Cross-sectional and longitudinal relationships. Schizophr Res 2020; 222:243-250. [PMID: 32527677 DOI: 10.1016/j.schres.2020.05.042] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 03/19/2020] [Accepted: 05/17/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Reports on the relationship between clinical insight and psychotic symptoms have shown inconsistent results, and the association between clinical insight and personality has rarely been addressed. The aim of this study was to examine whether personality is correlated cross-sectionally with insight level, and longitudinally with change in insight, beyond symptoms. METHODS Participants were a sub-sample of the Dutch Genetic Risk and Outcome of Psychosis (GROUP) project. Two hundred and eleven participants diagnosed with non-affective psychotic disorders took part in the cross-sectional part of the study, of whom 136 took part in the three-year follow-up assessment. They were administered with self-report Birchwood insight scale and NEO-Five Factor Inventory, and clinicians assessed them according to PANSS and CDS symptoms scales. RESULTS Cross-sectional analysis showed baseline self-report insight was positively related to neuroticism and agreeableness and negatively related to extraversion. Longitudinal analysis showed change in level of self-reported insight was predicted by baseline-insight and change in symptoms of disorganization. Personality factors did not predict insight change (as measured either by self-report or by clinician assessment). DISCUSSION The cross-sectional findings showed self-report insight (as opposed to clinician-rated) is associated with personality traits, suggesting negative affect is related to higher level of insight and that having insight may be influenced by the wish to comply with views of professionals, or a tendency to cover up problems. The longitudinal findings imply that not personality but change in severity of symptoms of disorganization, and possibly other variables, predicts change in insight.

Abstract
OBJECTIVES To investigate recorded poor insight in relation to mental health and service use outcomes in a cohort with first-episode psychosis. DESIGN We developed a natural language processing algorithm to ascertain statements of poor or diminished insight and tested this in a cohort of patients with first-episode psychosis. SETTING The clinical record text at the South London and Maudsley National Health Service Trust in the UK was used. PARTICIPANTS We applied the algorithm to characterise a cohort of 2026 patients with first-episode psychosis attending an early intervention service. PRIMARY AND SECONDARY OUTCOME MEASURES Recorded poor insight within 1 month of registration was investigated in relation to (1) incidence of psychiatric hospitalisation, (2) odds of legally enforced hospitalisation, (3) number of days spent as a mental health inpatient and (4) number of different antipsychotic agents prescribed; outcomes were measured over varying follow-up periods from 12 months to 60 months, adjusting for a range of sociodemographic and clinical covariates. RESULTS Recorded poor insight, present in 48.9% of the sample, was positively associated with youngest and oldest age groups, unemployment and schizophrenia (compared with bipolar disorder) and was negatively associated with Asian ethnicity, married status, home ownership and recorded cannabis use. It was significantly associated with higher levels of all four outcomes over the succeeding 12 months. Associations with hospitalisation incidence and number of antipsychotics remained independently significant when measured over 60 and 48 months, respectively. CONCLUSIONS Recorded poor insight in people with recent onset psychosis predicted higher subsequent inpatient mental healthcare use. Improving insight might benefit patients' course of illness as well as reduce mental health service use.

Abstract
OBJECTIVE Impaired insight is common in schizophrenia and may be affected by changes that occur with aging. There have been a few nonprospective investigations of insight in older adults with schizophrenia (OAS). This study examines the temporal fluctuations that occur with insight-defined as "awareness of mental illness" (dichotomized into presence or absence)-along with associated factors that influence illness awareness (IA) in OAS. METHODS The sample consisted of 103 persons derived from an initial sample of 250 community-dwelling persons aged 55 and over with early-onset schizophrenia spectrum disorder. Mean follow-up was 53 months. We examined 27 potential predictor variables of IA along with 5 covariates in bivariate analysis. The significant variables were then examined using multiple regression analyses. RESULTS 23% of persons transitioned between presence and absence of IA, 62% had persistent IA, and 15% never had IA. At baseline, fewer negative symptoms (blunted affect), higher cognitive functioning (conceptualization), younger age, higher educational levels, and more physical disorders were associated significantly with higher rates of IA at follow-up. Baseline IA did not predict any variables at follow-up. CONCLUSION IA is often unstable in later life, with nearly one-fourth of persons showing fluctuations. Although younger age predicted IA over time, other factors associated with aging, such as cognitive functioning and physical disorders, had additional independent effects on IA. The impact of IA on clinical and functional variables attenuated over time, suggesting that for many OAS, IA may have a limited role in enhancing long-term outcomes.

Abstract
PURPOSE The study aimed to investigate the relationship among self concepts, health locus of control, cognitive functioning and health-promoting lifestyles in patients diagnosed with schizophrenia. We examined health-promoting lifestyles through self-efficacy, self-esteem, health locus of control and neurocognitive factors. METHOD Fifty-six people with schizophrenia were enrolled in the study group. All subjects participated in the self-esteem (Rosenberg Self-Esteem Scale), self-efficacy (General Self-Efficacy Scale), health locus of control (The Multidimensional Health Locus of Control Scales), health-promoting lifestyles (Health Promotion Life-style Profile-II) and a series of neurocognitive measures. FINDINGS Stepwise regression analysis revealed that self-efficacy, internal health locus of control and attentional set-shifting accounted for 42% of the variance in total health-promoting lifestyles scores. Self-efficacy, self-esteem, internal and powerful others health locus of control and attentional set-shifting were significant predictors for domains of health-promoting lifestyles, respectively. CONCLUSION Study findings can help mental health professionals maintain and improve health-promoting behaviors through a better understanding of self-esteem, self-efficacy, health locus of control and neurocognitive functioning among people with schizophrenia.

Abstract
Objective: Cognitive models suggest that the self-concept of persons with psychosis can be fundamentally affected. Self-concepts were found to be related to different symptom domains when measured concurrently. Longitudinal investigations to disentangle the possible causal associations are rare. Method: We examined a sample of 160 people with a diagnosis of schizophrenia who took part in a psychotherapy study. All participants had the DSM-IV diagnosis of a schizophrenia and pronounced negative symptoms. Neurocognition, symptoms, and self-concepts were assessed at two time points 12 months apart. Structural equation modeling was used to test whether symptoms influence self-concepts (scar-model) or self-concepts affect symptoms (vulnerability model). Results: Negative symptoms correlated concurrently with self-concepts. Neurocognitive deficits are associated with more negative self-concepts 12 months later. Interpersonal self-concepts were found to be relevant for paranoia. Conclusion: The findings implicate that if deficits in neurocognition are present, fostering a positive self-concept should be an issue in therapy. Negative interpersonal self-concept indicates an increased risk for paranoid delusions in the course of 1 year. New aspects for cognitive models in schizophrenia and clinical implications are discussed.

Abstract
Self-concept is deeply affected in schizophrenia. Positive symptoms in particular are related to disturbed self/other distinctions. The neural networks underlying self-evaluation in schizophrenia have barely been investigated. The study reported here involved 13 patients with schizophrenia and 13 matched controls. During functional MRI, participants decided in three conditions whether the presented positive and negative personality traits characterized themselves, an intimate person, or included a certain letter. Based on the responses, each experimental condition was designed using a flexible factorial model. Controls and patients showed a similar behavioral pattern during self-evaluation, with group comparison revealing decreased activation in patients in the left inferior temporal gyrus and both temporal poles during self-ascription of traits, and in the anterior medial prefrontal cortex during evaluation of an intimate person. In patients, positive symptoms correlated positively with brain activation in the left parahippocampus during trait self-ascription. Hence, while evaluating themselves, schizophrenia patients revealed decreased activation in areas related to self-awareness overlapping with networks involved in theory of mind, empathy and social knowledge. Moreover, patients' brain activation during self-reflection was affected by the current positive symptomatology. The close interaction between self and other highlights the clinical and social relevance of self-processing deficits in schizophrenia.

Abstract
OBJECTIVE This study evaluated the relationship among insight, sociodemographic and clinical variables, symptoms and cognitive functions in a population of outpatients with stable schizophrenia, in order to identify possible contributing factors to awareness. METHOD Two-hundred and seventy-six consecutive outpatients with stable schizophrenia were enrolled in a cross-sectional study. All subjects were assessed by psychiatric scales and interview, and a wide neuropsychological battery. A factor analysis was performed to identify cognitive factors and multiple regression analyses were executed to test the contribution of variables considered to insight. RESULTS Our results showed that positive and negative symptoms, executive functions, verbal memory-learning were contributors of awareness of mental illness; positive and negative symptoms explained variability in awareness of the need for treatment; positive symptoms and executive functions contributed to awareness of the social consequences of disorder. CONCLUSIONS These results suggested that insight was partially influenced by positive and negative symptoms and by cognitive functions. A complex system of overlapping variables may underlie impaired insight, contributing to a different extent to specific dimensions of poor insight in patients with stable schizophrenia.

Abstract
Cognitive insight refers to awareness of one's own thinking. Research has found deficits in cognitive insight in schizophrenia but studies of its links with positive symptoms and delusions have been equivocal. One possibility is that the association of cognitive insight with positive symptoms and delusions is moderated by other factors. To explore this issue this study examined whether level of socially naive self-appraisal moderated the relationship of two forms of cognitive insight, self-reflectivity and self-certainty with delusions and positive symptoms. Participants were 92 adults, with diagnoses of schizophrenia or schizoaffective disorder, who were administered the Positive and Negative Syndrome Scale, self-deceptive subscale from the Marlowe-Crowne Social Desirability Scale and the Beck Cognitive Insight Scale. Stepwise multiple regressions with the interaction term of the predictive and moderator variables suggested that social naiveté moderates the relationship between self-reflectivity and self-certainty with positive symptoms in general. Moreover, association between self-certainty and delusions was also moderated by social naiveté self-appraisal. All models were significant after controlling for willful impression management as well as a measure of executive function. Results suggest that higher levels of self-certainty are a risk factor for having greater positive symptoms including more severe levels of delusions, when one has a view of oneself that is not tempered by the perceptions of others. Concerning lower levels of self-reflectivity it may be that this combined with a socially naïve view of oneself leaves persons less inhibited when they are tempted to accept unusual thoughts and perceptions as accurate. Implications for treatment are discussed.

Abstract
Research on emotional experience has indicated that subjects with schizophrenia experience less positive, and more negative emotional experience than non-psychiatric subjects in natural settings. Differences in the experience of emotion may result from differences in experiences such that everyday activities may evoke emotions. The purpose of this study was to identify if everyday experience of competence and autonomy were related to positive and negative emotion. Adults with schizophrenia spectrum disorders were recruited from day treatment programs (N=45). Data were collected using experience-sampling methods. A number of subjects failed to meet data adequacy (N=13) but did not differ from retained subjects (N=32) in symptoms or cognition. Positive and negative emotion models were analyzed using hierarchical linear modeling Everyday activities were characterized by those reported as easily accomplished and requiring at most moderate talents. Positive emotional experiences were stronger than negative emotional experiences. The majority of variance in positive and negative emotion existed between persons. Negative symptoms were significantly related to positive emotion, but not negative emotion. The perception that motivation for activity was external to subjects (e.g. wished they were doing something else) was related to decreased positive emotion and enhanced negative emotion. Activities that required more exertion for activities was related to enhanced positive emotion, whereas activities that subjects reported they wanted to do was associated with reduced negative emotion. The implications of this study are that everyday experiences of people with schizophrenia do affect emotional experience and that management of experience to enhance positive emotion may have therapeutic benefits.
