The association between psychosocial stress, interpersonal sensitivity, social withdrawal and psychosis relapse: a systematic review. SCHIZOPHRENIA (HEIDELBERG, GERMANY) 2023; 9:22.

Abstract
Psychosis is associated with a high risk of relapse, with 67% of clients relapsing within one year following a first episode. In light of the high personal, social, and healthcare costs of the illness, it is paramount to understand the risk factors associated with psychosis relapse. The current systematic review aims to critically review the role of psychosocial stress in psychosis relapse in individuals with an established psychotic disorder. This review systematically searched Ovid (PsycINFO, EMBASE, MEDLINE) literature databases from inception until 28th February 2022. Sixteen studies were eligible for inclusion. Most studies found that individuals with psychosis demonstrate high levels of psychosocial stress and are more likely to be socially withdrawn compared to healthy controls or other clinical presentations. Most studies reported a statistically significant association between psychosocial stress and psychosis relapse, as well as between social withdrawal and psychosis relapse. However, no studies examined the association between high levels of interpersonal sensitivity and psychosis relapse. Individuals with psychosis tend to experience high levels of psychosocial stress and social withdrawal, and these appear to increase the risk of psychosis relapse. Due to high levels of heterogeneity within the literature, we could only conduct a narrative synthesis of the findings. Future studies would benefit from employing a meta-analytic approach.

Abstract
BACKGROUND Life events (LEs) are a risk factor for first onset and relapse of psychotic disorders. However, the impact of LEs on specific symptoms - namely reality distortion, disorganization, negative symptoms, depression, and mania - remains unclear. Moreover, the differential effects of negative v. positive LEs are poorly understood. METHODS The present study utilizes an epidemiologic cohort of patients (N = 428) ascertained at first-admission for psychosis and followed for a decade thereafter. Symptoms were assessed at 6-, 24-, 48-, and 120-month follow-ups. RESULTS We examined symptom change within-person and found that negative events in the previous 6 months predicted an increase in reality distortion (β = 0.07), disorganized (β = 0.07), manic (β = 0.08), and depressive symptoms (β = 0.06), and a decrease in negative symptoms (β = -0.08). Conversely, positive LEs predicted fewer reality distortion (β = -0.04), disorganized (β = -0.04), and negative (β = -0.13) symptoms, and were unrelated to mood symptoms. A between-person approach to the same hypotheses confirmed that negative LEs predicted change in all symptoms, while positive LEs predicted change only in negative symptoms. In contrast, symptoms rarely predicted future LEs. CONCLUSIONS These findings confirm that LEs have an effect on symptoms, and thus contribute to the burden of psychotic disorders. That LEs increase positive symptoms and decrease negative symptoms suggest at least two different mechanisms underlying the relationship between LEs and symptoms. Our findings underscore the need for increased symptom monitoring following negative LEs, as symptoms may worsen during that time.

Emotional Comprehension Is Not Related to Duration of Distress from Daily Life Events. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18020459. [PMID: 33430055 PMCID: PMC7827275 DOI: 10.3390/ijerph18020459] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/25/2020] [Revised: 12/04/2020] [Accepted: 12/30/2020] [Indexed: 11/21/2022]
Abstract
The main aim of this paper is to analyze to what extent insight (i.e., mentalization referring to one’s own mental state) moderates recovering from daily life events. A total of 110 participants (84.5% women; mean age: M = 21.5; SD = 3.2) filled in the Trait Meta-Mood Scale (TMMS-24) and the Eysenck Personality Questionnaire (EPQ-R), and were interviewed about impairment derived from daily life events (everyday life stresses) during the past year. Multivariate regression models were adjusted for neuroticism, sex, and socioeconomic status to analyze whether different degrees of insight moderated the relationship between the intensity and the duration of emotional distress. Results showed that the global measure of insight did not moderate recovering from daily-life distress. Regarding the subdimensions, attention to emotional reactions was related to an increased duration of distress. Results showed that, against our hypothesis, deeper comprehension of emotional reactions, operationalized here as “true insight”, was not associated to faster recovery. Limitations and recommendations for further studies are discussed considering these results.

Abstract
Evidence for psychological risk factors on prodromal state of psychosis remained limited and inconsistent. This study aimed to investigate childhood trauma, life events and social support in subjects with high risk for psychosis (HR), first episode psychosis with schizophrenia (FEP) and healthy control (HC). In the study, 56 FEP, 83 HR and 61 HC underwent face-to-face clinical interview and psychological assessment, including Childhood Trauma Questionnaire (CTQ), Life Events Scale (LES) and Perceived Social Support Scale (PSSS). The results showed that in univariate analysis, HR individuals had more childhood trauma, more recent life events and less social support than HC group, and these findings were also supported by ANCOVA analysis except for the results related to social support after taking age, education, marital and employment status as covariates. Logistic regression analysis revealed that HR group was significantly associated with more childhood trauma, poorer overall function and unmarried state than HC group after controlling the interfering factors. HR group was similar with FEP group in these assessments. In conclusion, HR individuals experienced more childhood trauma, life events and social support deficit than HC group, which may be risk factors of conversion to psychosis. Further explorations are warranted to develop optimal psychosocial interventions.

Abstract
Life events are commonly reported to be related to psychosis. However, less attention has been given to the role that recent events play on psychosis, in relation to exposure to childhood adversity. The current study aimed to evaluate the relationship between recent events and psychosis, taking into account the role of early adversities. 78 psychotic patients and 156 controls were enrolled. Childhood adversity was evaluated using a validated semi-structured interview and the Childhood Experience of Care and Abuse Questionnaire. Recent events were recorded using a semi-structured interview with a normative and contextual approach. The diagnosis of psychosis was made according to Jablenski's criteria. Chi-square, t-test, odds ratio, and binary logistic regression statistical analyses were performed. Psychotic patients reported an excess of recent events. The occurrence of more than one recent event increased the risk of psychosis; there was a cumulative effect between recent and childhood events on psychosis. Recent events were significantly related to psychosis, even in the absence of childhood adversity or when adjusted for it. Our findings suggested that the effect of recent events on psychosis may be amplified by previous exposure to early adversity. Recent events alone, could be also linked to psychosis independently of childhood adversity.

Abstract
Negative life events can exacerbate symptoms in schizophrenia, but there is no literature on the effect on psychotic symptoms of positive life events. The purpose of this review was to scan the literature that studies how the joy that accompanies positive life events can be dampened and dismissed or, alternatively, savored and maintained, and how this contrast applies to schizophrenia. A literature search elicited 53 articles relevant to schizophrenia. Schizophrenia was found to be linked with difficulties in the processing of reward, in feeling that one was deserving of a reward, in sharing news of positive events, in knowing with whom to share, in knowing how to elicit a positive response from listeners when communicating good news, and in ensuring that positive feelings endure. There was no evidence that positive life events reduce psychosis symptoms but teaching the various skills of how to capitalize on good fortune can nevertheless improve the quality of life of individuals with schizophrenia.

Abstract
INTRODUCTION Recent life events are associated with transition to and outcome in psychosis. Childhood trauma and personality characteristics play a role in proneness to adult life events. However, little is known about the relative contribution and interrelatedness of these characteristics in psychotic disorders. Therefore, we investigated whether Five-Factor Model (FFM) personality traits and childhood trauma (abuse and neglect) predict adult life events, and whether the effect of childhood trauma on life events is mediated by personality traits. METHOD One hundred and sixty-three patients with psychotic disorders were assessed at baseline on history of childhood maltreatment and FFM personality traits, and on recent life events at 3-year follow-up. RESULTS Childhood abuse is associated with negative life events, and part of the effect of childhood abuse on negative life events is mediated by openness to experience. Openness to experience and extraversion are associated with more positive and negative life events. Childhood neglect and lower extraversion are related to experiencing less positive events. CONCLUSION The association between childhood trauma and recent life events is partly mediated by personality. Future research could focus on mechanisms leading to positive life events, as positive life events may buffer against development of mental health problems.

Abstract
BACKGROUND This study investigates the relationships between life events and chronic physical conditions among left behind farmers, a newly emerged weak group in vast rural China. METHODS The study collected information about life events, chronic physical conditions, blood pressure and fasting blood glucose from 4681 famers living in 18 randomly selected villages (Lu'an, Anhui, China) from early November 2013 to the end of December 2013. It compared the risk and odds ratios (RRs/ORs) among different subgroups divided according two life event indices derived by adding up un-weighted-ratings and weighted-ratings based on multivariate logistic regression coefficients respectively. RESULTS A total of 4040 (86.3 % eligible) farmers completed the survey. RRs between farmers with lower than the first 1/15-percentile of life event index and with higher life event index scores ranged 1.43-5.79 for chronic gastritis and 0.42-9.07 for prostatitis, 1.01-4.97 for cervicitis/vaginitis, 1.45-3.28 for cardio-cerebrovascular diseases, 1.12-1.58 for hypertension, 1.00-1.66 for diabetes, 1.07-3.35 for pre-diabetes and 5.00-55.00 for "other chronic physical conditions". CONCLUSIONS Life events were independently linked with most of the chronic physical conditions in a dose-effectiveness way. RRs between subgroups divided by given percentile cutoff points of life event index compiled using logistic regression models turned out to be substantially higher than that between subgroups divided by same cutoff points of life event index produced via summing up the un-weighted Likert ratings of all the events studied.

Abstract
INTRODUCTION Recent models of psychosis implicate stressful events in its etiology. However, while evidence has accumulated for childhood trauma, the role of adult life events has received less attention. Therefore, a review of the existing literature on the relationship between life events and onset of psychotic disorder/experiences is timely. METHODS A search was conducted using PsychInfo, Medline, Embase, and Web of Science to identify studies of life events and the onset of psychosis or psychotic experiences within the general population. Given previous methodological concerns, this review included a novel quality assessment tool and focused on findings from the most robust studies. A meta-analysis was performed on a subgroup of 13 studies. RESULTS Sixteen studies published between 1968 and 2012 were included. Of these, 14 reported positive associations between exposure to adult life events and subsequent onset of psychotic disorder/experiences. The meta-analysis yielded an overall weighted OR of 3.19 (95% CI 2.15-4.75). However, many studies were limited by small sample sizes and the use of checklist measures of life events, with no consideration of contextual influences on the meaning and interpretation of events. CONCLUSIONS Few studies have assessed the role of adult life events in the onset of psychosis. There was some evidence that reported exposure to adult life events was associated with increased risk of psychotic disorder and subclinical psychotic experiences. However, the methodological quality of the majority of studies was low, which urges caution in interpreting the results and points toward a need for more methodologically robust studies.

Abstract
OBJECTIVE To assess the applicability, interpretability and potential limitations of an adverse event screening questionnaire (the Enhancing Quality Use of Medication Self-Reported Questionnaire [EQUIM-SRQ]) in an Australian mental health outpatient population. METHOD Questionnaires were distributed amongst two Australian adult mental health clinics for completion either at the clinic (onsite), or externally (postal option), during March-May 2011. Assistance was offered to participants completing the questionnaire onsite. Clients who were visited in their homes by clinic staff were invited to participate as external participants. RESULTS Of 160 questionnaires distributed, 29 (18%) were completed. Of those, 22 were completed onsite, and seven were completed externally. Of the questionnaires completed onsite, 11 were fully completed, with 4 participants requiring assistance. A further 11 questionnaires were partially completed, with 2 participants requiring assistance. Of the questionnaires completed externally, 5 were fully completed. CONCLUSION Although the response rate was low, the EQUIM-SRQ was applicable, interpretable and acceptable when completed or partially completed questionnaires were assessed. The potential exists to apply the EQUIM-SRQ in further research, and thereafter, clinical practice.

Abstract
OBJECTIVE Recent studies have suggested that early adverse events, such as childhood trauma, may promote enduring liability for psychosis whereas more recent adverse events may act as precipitants. Examination of these environmental dynamics, however, requires prospective studies in large samples. This study examines whether the association between recent adverse events and psychosis is moderated by exposure to early adversity. METHOD A random regional representative population sample of 3021 adolescents and young adults in Munich, Germany, was assessed three times over a period of up to 10 years, collecting information on sociodemographic factors, environmental exposures, and measures of psychopathology and associated clinical relevance. Evidence of statistical non-additivity between early adversity (two levels) and more recent adversity (four levels) was assessed in models of psychotic symptoms. Analyses were a priori corrected for age, gender, cannabis use, and urbanicity. RESULTS Early and recent adversity were associated with each other (RR = 1.32, 95% CI 1.06-1.66; P = 0.014) and displayed statistical non-additivity at the highest level of exposure to recent adversity (χ(2) = 4.59; P = 0.032). CONCLUSION The findings suggest that early adversity may impact on later expression of psychosis either by increasing exposure to later adversity and/or by rendering individuals more sensitive to later adversity if it is severe.

Abstract
OBJECTIVE Reactive delusional disorder (DD) (with a precipitating factor) has been postulated to differ clinically from nonreactive DD and to show a better prognosis. Our study tests this hypothesis in a sample of patients with persistent DD (International Classification of Diseases, 10th Revision) or DD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) followed during a period of more than 10 years. METHOD As part of a long-term study on DD, 19 patients with DD and a stressful life event preceding the onset of the disorder were compared with 24 DD patients without such a life event. Diagnoses, social and biographical data, life events, and outcome were assessed by a semistructured interview and validated rating scales. Personality features were assessed by the NEO Five-Factor Inventory and by the Inventory of Clinical Personality Accentuations. RESULTS Patients with reactive DD tended to be somewhat younger but showed otherwise little differences to patients with nonreactive DD. In particular, there were no differences in the course of the disorder. However, patients with reactive DD were significantly more often in a stable relationship and showed higher values on neuroticism and more pronounced dependent and borderline personality accentuations in dimensional personality measures. CONCLUSIONS Reactive DD was not found to have a better prognosis than nonreactive DD. However, the results suggest an increased vulnerability for interpersonal conflicts in these patients.

Abstract
This study aimed to identify the impact of life events on psychotic relapse in individuals with an established diagnosis of schizophrenia to explore their proneness to experience life events, to examine if any effect of life events was cumulative or triggering in nature and to explore if specific types of events influence subsequent symptom formation. An association between adverse life events and relapse in people with schizophrenia has been reported in several studies; however, the nature of the association remains unclear. Some studies suggest that intrusive events promote the formation of paranoid psychotic symptoms. Using well-validated semi-structured interview schedules the author interviewed participants during or shortly after relapse. The severity and intrusiveness of life events was rated and relationships between events and symptoms were explored. Increasing numbers of patients experienced life events especially moderately threatening life events in the last 4 weeks prior to relapse; however, no relationship was discovered between life events in general or specifically intrusive life events and the specific content of psychotic symptoms. An increased frequency of milder life events occurred in the 2 months prior to relapse, suggesting that chronic illness is not associated with absence of mild or moderately severe life events or with diminished sensitivity to them.
