ABSTRACT

BACKGROUND: People with schizophrenia often experience long-term psychosocial disabilities and frequent relapse. Family plays a key role in caring for ill relatives, which in turn probably contributes to high levels of distress and burdens for the family. Family-based interventions have been developed and applied to family members and their relatives with schizophrenia to improve their outcomes. This is an update of a Cochrane review that was last updated in 2011, which has been split into this review, one on group- versus individual-based family interventions and one on family-based cognitive versus behavioural management interventions. OBJECTIVES: To assess the effects of family-based interventions for people with schizophrenia or schizophrenia-like disorders and their families compared with standard care. SEARCH METHODS: We searched the following electronic databases from inception until April 2023: CENTRAL, Medline, Embase, PsycInfo, CINAHL, WHO International Clinical Trials Registry Platform (ICTRP), Clinicaltrials.gov, SinoMed, China Network Knowledge Infrastructure (CNKI), Wanfang, and Chinese Scientific Journals Database (VIP). We also searched the reference lists of included studies and accessible reviews for additional references. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared the effects of family-based interventions for people with schizophrenia or schizophrenia-like disorders and their families and reported at least one patient's and one family member's outcomes. In this update, we only investigated standard care as the comparator. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. The review authors independently screened studies, extracted data, and assessed risk of bias for each study using the Cochrane risk of bias tool for RCTs. We pooled data and estimated effects with the mean difference (MD), standardised mean difference (SMD), or risk ratio (RR) with 95% confidence interval (CI). We judged the certainty of evidence using GRADEpro GDT. We divided the outcomes into short-term (≤ 1 month postintervention), medium-term (> 1 to 6 months postintervention), and long-term follow-up (> 6 months postintervention), if available. MAIN RESULTS: We identified 26 RCTs in this review, with 1985 people with schizophrenia or schizophrenia-like disorders, and 2056 family members. Most family-based interventions were conducted on a weekly or biweekly basis, with duration ranging from five weeks to two years. We had substantial concerns regarding the methodological quality of the included studies given that we judged all studies at high risk of performance bias and several studies at high risk of detection, attrition or reporting bias. Low-certainty evidence indicated that family-based interventions may reduce patients' relapse at one month or less postintervention (RR 0.66, 95% CI 0.49 to 0.89; 4 RCTs, 229 participants). We downgraded the evidence by two levels due to imprecision (small number of participants) and high risk of performance, detection and attrition bias. Compared to standard care, family-based interventions probably reduce caregiver burden at one month or less postintervention (MD -5.84, 95% CI -6.77 to -4.92; 8 RCTs, 563 participants; moderate-certainty evidence) and may result in more family members shifting from high to low expressed emotion (RR 3.90, 95% CI 1.11 to 13.71; 2 RCTs, 72 participants; low-certainty evidence). Family interventions may result in little to no difference in patients' death (RR 0.48, 95% CI 0.18 to 1.32; 6 RCTs, 304 participants; low-certainty evidence) and hospital admission (≤ 1 month postintervention; RR 0.81, 95% CI 0.51 to 1.29; 2 RCTs, 153 participants; low-certainty evidence) in comparison with standard care. Due to the heterogeneous measures and various follow-up periods, we were unable to provide pooled effect estimates for patients' compliance with medication and quality of life. We were very uncertain whether family interventions resulted in enhanced compliance with medication and improved quality of life for patients. We downgraded the evidence to very low certainty due to high risk of bias across studies, inconsistency (different directions of effects across studies), and imprecision (small number of participants or CIs of most studies including the possibility of no effect). AUTHORS' CONCLUSIONS: This review synthesised the latest evidence on family interventions versus standard care for people with schizophrenia or schizophrenia-like disorders and their families. This review suggests that family interventions might improve patients' outcomes (e.g. relapse) and families' outcomes (e.g. caregiver burden and expressed emotion), with little to no difference in patients' hospital admission and adverse effects in terms of death. However, evidence on patients' compliance with medication and quality of life was very uncertain. Overall, the evidence was of moderate to very low certainty. Future large and well-designed RCTs are needed to provide more reliable evaluation of effects of family interventions in people with schizophrenia or schizophrenia-like disorders and their families.

ABSTRACT

OBJECTIVE: Conceptual similarities between depressive and negative symptoms complicate biomarker and intervention development. This study employed a data-driven approach to delineate the neural circuitry underlying depressive and negative symptoms in schizophrenia spectrum disorders (SSDs). METHODS: Data from three studies were analyzed (157 participants with SSDs) to assess brain-behavior relationships: two neuroimaging studies and a randomized trial of repetitive transcranial magnetic stimulation (rTMS). Partial least squares correlation (PLSC) was used to investigate associations between resting-state functional connectivity and depressive and negative symptoms. Secondary analyses of rTMS trial data (active, N=37; sham, N=33) were used to assess relationships between PLSC-derived symptom profiles and treatment outcomes. RESULTS: PLSC identified three latent variables (LVs) relating functional brain circuitry with symptom profiles. LV1 related a general depressive symptom factor with positive associations between and within the default mode network (DMN), the frontoparietal network (FPN), and the cingulo-opercular network (CON). LV2 related negative symptoms (no depressive symptoms) via negative associations, especially between the FPN and the CON, but also between the DMN and the FPN and the CON. LV3 related a guilt and early wakening depression factor via negative rather than positive associations with the DMN, FPN, and CON. The secondary visual network had a positive association with general depressive symptoms and negative associations with guilt and negative symptoms. Active (but not sham) rTMS applied bilaterally to the dorsolateral prefrontal cortex (DLPFC) reduced general depressive but not guilt-related or negative symptoms. CONCLUSIONS: The results clearly differentiate the neural circuitry underlying depressive and negative symptoms, and segregated across the two-factor structure of depression in SSDs. These findings support divergent neurobiological pathways of depressive symptoms and negative symptoms in people with SSDs. As treatment options are currently limited, bilateral rTMS to the DLPFC is worth exploring further for general depressive symptoms in people with SSDs.

ABSTRACT

AIM: Functional Management and Recovery is a standardized Psychoeducational Intervention, derived from "Integro", an effective salutogenic-psychoeducational intervention for people in recovery journey, designed to improve recovery and functioning of individuals with psychotic disorders in Psychiatric Residential Facilities (PRFs). The aim of this study is to evaluate the primary and secondary outcomes of this intervention elaborated specifically for PRFs where evidence based structured interventions seem rare and desirable. METHODS: 66 individuals with psychotic disorders were recruited in 9 PRFs dislocated in the North, Center and South Italy and 63 underwent a multicenter follow-up study with a two time-point evaluation (t0, pre-treatment and t1, 6 months; ). At each time point, social functioning was assessed as primary outcome by the Personal and Social Performance scale (PSP); furthermore, psychopathological status was assessed by Brief Psychiatric Rating Scale (BPRS), Recovery by Recovery Assessment Scale (RAS), Cognitive Functioning by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Stress management by Stress-Scale, Cognitive Flexibility by Modified Five-Point Test (M-FPT), Emotional Intelligence by Emotional Intelligence Index (EI-I), the PRF Atmosphere and the Opinion of users about the PFR by an ad hoc questionnaire. The Abilities Knowledge, the Utility and Pleasantness of sessions were measured by an ad hoc list of items. RESULTS: 63 individuals out of 66, 52 (82,5%) affected by schizophrenia and 11 (17,5%) by bipolar I disorder with psychotic symptoms according to DSM-5-TR completed the study. At the end of the study, 43 (68,3%) were male, 57 (90.5%) were single, 5 (7.9%) engaged, 1 (1.6%) married; 45 (71.4%) unemployed. The total scores of PSP, RAS, BPRS, BANS, Stress management, Abilities Knowledge, Utility and Pleasantness of sessions showed a statistically significant improvement at t1 vs. t0. Two sub-scales out of 5 of M-FPT showed a statistically significant improvement. The Emotional Intelligence, the Unit Atmosphere and the Opinion of Users about PFR improved without statistical significance. Six months after the end of the follow-up study 22 individuals of the sample were dismissed with a very high turnover. CONCLUSIONS: After a six-month follow-up (a short period of time), these results showed improvement in functioning, the primary outcome, as well as in the following secondary outcome variables: RAS, BPRS, BANS, Stress management, Abilities Knowledge, two sub-scales out of 5 of M-FPT, Utility and Pleasantness of sessions. Overall, a remarkable impact of psychoeducational structured intervention on the key Recovery variables is observed. Further studies are needed to address extent and duration of these improvements.

ABSTRACT

BACKGROUND: Adults with schizophrenia experience a range of neurocognitive problems that affect their daily functioning. Evidence for the efficacy of cognitive remediation in schizophrenia has been established, but its implementation in under-resourced community-based settings is less well-studied. In recent years, interventions have also focused on the strategy-learning approach in favor of drill-and-practice. Moreover, there is an increasing recognition to address social cognition and negative symptoms alongside neurocognition. This study attempts to carry out cognitive remediation in a community mental health setting. The Neuropsychological and Educational Approach to Remediation (NEAR) is used as the cognitive remediation intervention. Neurocognitive and social cognitive games will be introduced during the computer-assisted cognitive exercises sessions. In addition, the instructional technique will foster the use of metacognition and cognitive strategies. Moreover, metamotivation training will be the focus of some bridging sessions to enhance motivation to engage in goal-directed learning behaviors. The aims of the study are to 1) investigate the effects of cognitive remediation on neurocognition, social cognition and functional outcomes of participants with schizophrenia/schizoaffective disorders in community mental health settings; and 2) explore the mediators for change (eg: metamotivation, metacognition and negative symptoms) in cognitive performance and functional outcomes. METHODS: This randomized controlled trial will be conducted in three Singapore Anglican Community Services (SACS) centers, where standard psychiatric rehabilitation is delivered. Participants who are randomized to the experimental arm will receive cognitive remediation and psychiatric rehabilitation, while those randomized to the control arm will receive standard psychiatric rehabilitation only. Cognitive remediation is carried out three times a week for 12 weeks. It consists of computer-assisted cognitive exercises, as well as bridging groups to aid transfer of learning to daily living. Baseline, post-intervention and eight-week follow-up measurements will be collected. Group by time differences in cognitive performance, negative symptoms, metamotivation, metacognition, functioning and recovery will be analyzed across the three time points. Mediators for improvement in cognitive performance and functioning will also be explored. DISCUSSION: Findings of this research will add to the body of knowledge about the key therapeutic ingredients within a strategy-based cognitive remediation program and improve its implementation within under-resourced community settings. TRIAL REGISTRATION: This study has been registered with ClinicalTrials.gov (ID: NCT06286202). Date of registration: 29 February 2024. Date of last update: 21 May 2024.

ABSTRACT

BACKGROUND: Cognitive-behavioral intervention techniques are increasingly demonstrating their efficacy in preventing relapses and managing problems in patients with schizophrenia. There is still variation in its effectiveness for negative symptoms, such as mood-related symptoms and motivation to engage socially. METHODS: A systematic search was conducted in PubMed, Web of Science for English literature on cognitive-behavioral therapy (CBT) interventions in patients with schizophrenia. The search included randomized controlled trials and nonrandomized controlled trials. The search period extended from the inception of the databases to September 30, 2022. Two researchers independently performed quality assessment and data extraction based on predefined inclusion and exclusion criteria. RESULTS: Discrepancies were resolved through discussion or consultation with a third researcher. Initially, 169 articles were retrieved through database searches and other means. After applying the inclusion and exclusion criteria, 10 randomized controlled studies were included in the final analysis. The intervention group comprised a total of 680 patients with schizophrenia, while the control group included 686 patients with schizophrenia. Meta-analysis results demonstrated a statistically significant difference in negative symptom reduction between the CBT intervention group (WMD = -1.19, 95% CI [-1.73, -0.66], P < .0001) and the control group. CONCLUSION: We have analyzed the effectiveness of CBT based on our previous research, CBT was found to effectively improve negative symptoms in individuals diagnosed with schizophrenia.

ABSTRACT

BACKGROUND: End of traditional institutionalized psychiatric care, diagnostic complexities, and associated stigma often negatively impact the social networks of caregivers, making them experience social isolation. Not the "identified patients", caregiver perspectives are typically overlooked further adding to anticipatory stigma resulting in social death among them. Caregiving experience results in developing coping skills, preventing carers from responding to the nuances of the context, and identifying the useful rules- "Experiential Avoidance". Psycho-education is typically combined with other formal treatment programs for case conceptualization, and to provide a clear rationale for the treatment approach but less as a distinct psychotherapy. Borrowing the philosophy of Functional Contextualism, the present study developed a "Present-Moment Awareness" guided psychoeducational intervention. The aim was to reduce schizophrenia caregiver burden and anticipatory stigma and promote the value of caregiver participation as 'experts by experience'. METHOD: Five family caregivers of remitted schizophrenia patients were recruited using purposive sampling. Pre-post measure was taken on caregiver burden, caregiving experience, sense of personal mastery, and caregiving competence. Results were analysed quantitatively and qualitatively. RESULTS: A significant decrease in caregiver burden, stigma, and negative effects on the family in post-intervention was observed. Self-compassion led to a rise in a sense of empowerment. CONCLUSION: A caregiver-centred "Present-Moment Awareness" guided psycho-education for schizophrenia caregivers can be considered a possible means to address perceived stigma in caregivers and to reduce associated distress of carers.

ABSTRACT

The period of time following discharge from an inpatient setting presents a unique window of opportunity for people with psychosis to engage in psychological treatment. In England, The National Institute for Health and Care Excellence (NICE) guidelines outline that every person with a schizophrenia diagnosis should be offered individual Cognitive Behavioural Therapy for psychosis (CBTp) and Family Intervention (FI). This study aimed to explore rates of offer and receipt of NICE recommended therapies for adults with a schizophrenia spectrum disorder diagnosis in the year following discharge from an inpatient unit. We then investigated possible predictors of therapy offer and receipt. We used a large electronic healthcare records database to perform a secondary data analysis. A generalised linear regression model was used to explore possible predictors. Overall, our results showed low rates of offer and receipt of recommended therapies (Any recommended therapy (CBT only, FI only or CBT + FI) received = 39(8%), offered = 70(15%)). Predictor variable results were identified and discussed. The low level of offer and receipt of recommended therapies is concerning given the recommendations in the NICE guidelines for people with psychosis. Our study highlighted the need for more consistent and reliable procedures for recording this information. Further investigation into the reasons for low levels of implementation overall is important to aid the development of recommendations for how this can be improved.

ABSTRACT

Introduction: Treating the early phase of schizophrenia is crucial for preventing further episodes and improving quality of life, functioning, and social inclusion. Pharmacotherapies are first-line treatments, but have limitations. There is consensus on the need for non-pharmacological interventions for individuals in the early phase of schizophrenia. Several psychological interventions have shown promising effects; however, their comparative effectiveness remains largely unknown. To address this issue, a network meta-analysis will be performed. We aim to develop a hierarchy of existing psychological treatments concerning their efficacy and tolerability, which will inform treatment guidelines. Protocol: Randomized controlled trials (RCTs) investigating psychological interventions for first-episode psychosis, first-episode schizophrenia, or early phase schizophrenia will be included. The primary outcome will be overall schizophrenia symptoms (measured up to 6 and 12 months, and at the longest follow-up) and relapse as a co-primary outcome. Secondary outcomes are premature discontinuation; change in positive, negative, and depressive symptoms of schizophrenia; response; quality of life; overall functioning; satisfaction with care; adherence; adverse events; and mortality. The study selection and data extraction are performed by two independent reviewers. We will assess the risk of bias of each study using the Cochrane Risk of Bias tool 2 and evaluate the confidence in the results using Confidence in Network Meta-Analysis (CINeMA). Subgroup and sensitivity analyses will be conducted to explore heterogeneity and assess the robustness of our findings. Discussion: This systematic review and network meta-analysis aims to compare multiple existing psychological interventions, establishing which are best for symptom reduction, relapse prevention, and other important outcomes in early phase schizophrenia. Our results may provide practical guidance concerning the most effective psychological intervention to reduce symptom severity and the societal burden associated with the disorder.

ABSTRACT

BACKGROUND: Digital mental health is a rapidly growing field with an increasing evidence base due to its potential scalability and impacts on access to mental health care. Further, within underfunded service systems, leveraging personal technologies to deliver or support specialized service delivery has garnered attention as a feasible and cost-effective means of improving access. Digital health relevance has also improved as technology ownership in individuals with schizophrenia has improved and is comparable to that of the general population. However, less digital health research has been conducted in groups with schizophrenia spectrum disorders compared to other mental health conditions, and overall feasibility, efficacy, and clinical integration remain largely unknown. OBJECTIVE: This review aims to describe the available literature investigating the use of personal technologies (ie, phone, computer, tablet, and wearables) to deliver or support specialized care for schizophrenia and examine opportunities and barriers to integrating this technology into care. METHODS: Given the size of this review, we used scoping review methods. We searched 3 major databases with search teams related to schizophrenia spectrum disorders, various personal technologies, and intervention outcomes related to recovery. We included studies from the full spectrum of methodologies, from development papers to implementation trials. Methods and reporting follow the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RESULTS: This search resulted in 999 studies, which, through review by at least 2 reviewers, included 92 publications. Included studies were published from 2010 to 2023. Most studies examined multitechnology interventions (40/92, 43%) or smartphone apps (25/92, 27%), followed by SMS text messaging (16/92, 17%) and internet-based interventions (11/92, 12%). No studies used wearable technology on its own to deliver an intervention. Regarding the stage of research in the field, the largest number of publications were pilot studies (32/92, 35%), followed by randomized control trials (RCTs; 20/92, 22%), secondary analyses (16/92, 17%), RCT protocols (16/92, 17%), development papers (5/92, 5%), and nonrandomized or quasi-experimental trials (3/92, 3%). Most studies did not report on safety indices (55/92, 60%) or privacy precautions (64/92, 70%). Included studies tend to report consistent positive user feedback regarding the usability, acceptability, and satisfaction with technology; however, engagement metrics are highly variable and report mixed outcomes. Furthermore, efficacy at both the pilot and RCT levels report mixed findings on primary outcomes. CONCLUSIONS: Overall, the findings of this review highlight the discrepancy between the high levels of acceptability and usability of these digital interventions, mixed efficacy results, and difficulties with sustained engagement. The discussion highlights common patterns that may underscore this observation in the field; however, as this was a scoping review, a more in-depth systematic review or meta-analysis may be required to better understand the trends outlined in this review.

ABSTRACT

Electroconvulsive therapy (ECT) is a well-established treatment option for individuals with treatment-resistant schizophrenia (TRS). However, predicting treatment response and identifying potential biomarkers to guide electroconvulsive therapy interventions in treatment-resistant schizophrenia remains a challenge. This review paper aims to explore the current literature on clinical biomarkers associated with electroconvulsive therapy in treatment-resistant schizophrenia. We discuss various potential biomarkers, including clinical, neuroimaging findings, EEG markers, and genetic markers, that have shown promise in predicting electroconvulsive therapy response and understanding the underlying mechanism of action. Additionally, we highlight the limitations and future directions for research in this field.

ABSTRACT

Low-frequency repetitive transcranial magnetic stimulation (rTMS) has emerged as an effective intervention for alleviating symptoms of psychiatric disorders, particularly schizophrenia characterized by persistent auditory verbal hallucinations (AVH). However, the underlying mechanism of its action remain elusive. This study employed a randomized controlled design to investigate the impact of low-frequency rTMS on the neural connectivity at the stimulate site, specifically left temporoparietal junction (TPJ), in schizophrenia patients with suffering from AVH. Using Dynamic Causal Modeling (DCM), this study assessed changes in directed connectivity patterns and their correlations with clinical symptomatology. The results demonstrated significant improvements in AVH. Notably, significant changes in connectivity were observed, including both abnormal functional connectivity and effective connectivity among multiple brain regions. Particularly, the inhibition effects from the left precentral gyrus and left medial superior frontal gyrus to the left TPJ were closely associated with improvements in AVH. These findings underscore the potential of rTMS to effectively modulate neural pathways implicated in hallucinations in schizophrenia, thereby providing a neurobiological foundation for its therapeutic effects.

ABSTRACT

OBJECTIVES: Negative symptoms in schizophrenia are associated with significant illness burden. We sought to investigate clinical outcomes for patients with schizophrenia who present with predominant negative symptoms (PNS) vs without PNS. DESIGN: Retrospective analysis of electronic health record (EHR) data. SETTING: 25 US providers of mental healthcare. PARTICIPANTS: 4444 adults with schizophrenia receiving care between 1999 and 2020. EXPOSURE: PNS defined as ≥3 negative symptoms and ≤3 positive symptoms recorded in EHR data at the time of the first recorded schizophrenia diagnosis (index date). Symptom data were ascertained using natural language processing applied to semistructured free text records documenting the mental state examination. A matched sample (1:1) of patients without PNS was used to compare outcomes. Follow-up data were obtained up to 12 months following the index date. PRIMARY OUTCOME MEASURE: Mean number of psychiatric hospital admissions. SECONDARY OUTCOME MEASURES: Mean number of outpatient visits, estimated treatment costs, Clinical Global Impression - Severity score and antipsychotic treatments (12 months before and after index date). RESULTS: 360 (8%) patients had PNS and 4084 (92%) did not have PNS. Patients with PNS were younger (36.4 vs 39.7 years, p<0.001) with a greater prevalence of psychiatric comorbidities (schizoaffective disorders: 25.0 vs 18.4%, p=0.003; major depressive disorder: 17.8 vs 9.8%, p<0.001). During follow-up, patients with PNS had fewer days with an antipsychotic prescription (mean=111.8 vs 140.9 days, p<0.001). Compared with matched patients without PNS, patients with PNS were more likely to have a psychiatric inpatient hospitalisation (76.1% vs 59.7%, p<0.001) and had greater estimated inpatient costs ($16 893 vs $13 732, p=0.04). CONCLUSIONS: Patients with PNS were younger and presented with greater illness severity and more psychiatric comorbidities compared with patients without PNS. Our findings highlight an unmet need for novel therapeutic approaches to address negative symptoms to improve clinical outcomes.

ABSTRACT

Racial disparities in diagnosis, treatment, and outcome have been well-established for people with schizophrenia. While cognitive remediation treatments have been shown to produce mild to moderate improvements in cognition for people with schizophrenia, few studies have examined racial/ethnic differences in treatment response. This study employed a secondary analysis of data from two randomized, single-blind controlled trials (N = 119) investigating the efficacy of two forms of cognitive training, to explore potential racial/ethnic differences in targeted outcomes. Given the extant literature, we predicted that racial/ethnic minorities would (1) drop out of the study at higher rates, (2) display greater levels of functional and cognitive impairment prior to treatment, and (3) display lower levels of improvement in cognitive and functioning outcomes following treatment. Our study revealed largely negative findings: white vs. non-white groups showed similar treatment drop-out rates, similar levels of cognitive impairment and symptom severity at study baseline and showed similar responses to cognitive training, with the exception of working memory in which participants' racial/ethnic minority status predicted significantly greater improvement in response to cognitive training. These findings suggest that cognitive remediation treatments are effective at addressing cognitive deficits in racial/ethnic minorities and supports cognitive remediation as a treatment which may help address racial/ethnic disparities in cognition. Given the scant research literature, future analyses should look at race as a potential mediator of treatment in a variety of evidence-based psychosocial treatments.

ABSTRACT

Schizophrenia poses significant challenges for individuals and caregivers, often leading to recurrent hospitalizations. Limited information on patients with schizophrenia and multiple hospitalizations in Romania is available in the scientific literature. Our study aimed to evaluate the characteristics of patients with schizophrenia with multiple hospitalizations in a single center in Cluj-Napoca, analyzing if specific patterns exist between patients with two or more hospitalizations or between men and women. We conducted a retrospective study on patients diagnosed with schizophrenia according to the 10th revision of the International Classification of Diseases (ICD 10), hospitalized at the County Emergency Hospital of Cluj-Napoca, Romania, between 2018 and 2022. Data on demographics, somatic comorbidities, symptom severity using the positive and negative syndrome scale (PANSS) or the brief psychiatric rating scale (BPRS), antipsychotic medication, and adverse effects were collected. We evaluated 62 patients, aged from 23 to 57 years, with 157 hospitalizations (ranging from two to seven per patient). No familial history of schizophrenia (56.5%) or bipolar disorder (71%) was reported by most patients. Forty-eight patients were male, and 45 had two hospitalizations. Age, sex, living place and conditions, season of birth, and marital status were similar in patients with two or more than two hospitalizations (p-values > 0.10). Significant differences were observed between patients with two or more than two hospitalizations regarding smoking (63.3% vs. 79.1%, p-value = 0.0029) and symptoms of fear at admission (40.0% vs. 65.7%, p-value = 0.0015). We observed lower scores in the overall PANSS and BPRS scores at discharge compared to admission (p-values < 0.001), regardless of the group (two or more than two hospitalizations, men vs. women). Men and women showed differences in hospitalization stays (median 17.25 vs. 15 days, p-value < 0.001) and BPRS scores at admission (p-value = 0.012) and discharge (p-value = 0.016). Fewer First-Generation Antipsychotics were prescribed for those with two admissions, and nearly half reported adverse effects, notably tachycardia (29%), with similar occurrence within groups. Our results showed that the candidate for multiple hospitalizations is a male, with a mean age of 37 years, unmarried, and living with someone in urban settings, more likely a smoker who exhibits fear symptoms.

ABSTRACT

Cognitive impairment is a core feature of schizophrenia spectrum disorders (SSD). Violent and aggressive behavior represents a complex issue in psychiatry, and people with SSD have been shown to be at risk of being both victims and perpetrators of violence. In this review, the complex relationship between cognitive impairment and violent behavior is explored, also considering the usefulness of treating cognitive impairment to improve violence-related outcomes. Several studies report that cognitive impairment is linked to violent behavior, but significant differences between domains and conflicting results are also present, leaving the identification of specific cognitive profiles predicting violent behavior in SSD as an important aim for future research. Evidence regarding the effectiveness of treating cognitive impairment to improve violent behavior, while heterogeneous, provides more consistent results: cognition-targeting interventions appear to provide significant benefits also in the prevention of aggression in people living with SSD, and preliminary evidence shows cognition-focused interventions targeting violent behavior improve both cognition- and violence-related outcomes. Implementing these interventions in clinical practice could be of great usefulness, particularly in forensic contexts. Physical exercise, which improves cognitive performance and psychosocial functioning in SSD, appears to reduce violent behavior in healthy individuals, but requires further studies in clinical samples.

ABSTRACT

BACKGROUND: Schizophrenia is a chronic mental illness characterized by delusions, hallucinations, and important functional and social disability. Interventions labeled as 'transitional' add to care plans made during the hospital stay in preparation for discharge. They also include interventions developed after discharge to support people with serious mental illness as they make the transition from the hospital to the community. Transitional discharge interventions may anticipate the future needs of the patient after discharge by co-ordinating the different levels of the health system that can effectively guarantee continuity of care in the community. This occurs through the provision of therapeutic relationships which give a safety net throughout the discharge and community reintegration processes to improve the general condition of users, level of functioning, use of health resources, and satisfaction with care. OBJECTIVES: To assess the effects of transitional discharge interventions for people with schizophrenia. SEARCH METHODS: On 7 December 2022, we searched the Cochrane Schizophrenia Group's Study-Based Register of Trials, which is based on CENTRAL, MEDLINE, Embase, PubMed, CINAHL, ClinicalTrials.gov, ISRCTN, PsycINFO, and WHO ICTRP. SELECTION CRITERIA: Randomized controlled trials (RCTs) evaluating the effects of transitional discharge interventions in people with schizophrenia and schizophrenia-related disorders. Eligible interventions included three key elements: predischarge planning, co-ordination of care and follow-up, and postdischarge support. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Outcomes of this review included global state (relapse), service use (hospitalization), general functioning, satisfaction with care, adverse effects/events, quality of life, and direct costs. For binary outcomes, we calculated risk ratios (RRs) and their 95% confidence intervals (CIs). For continuous outcomes, we calculated the mean difference (MD) or standardized mean difference (SMD) and their 95% CIs. We used GRADE to assess certainty of evidence. MAIN RESULTS: We found 12 studies with 1748 participants comparing transitional discharge interventions to usual care. All were parallel-group RCTs. No studies assessed global state (relapse) or reported data about adverse events/effects. All studies had a high risk of bias, mainly due to serious concerns about allocation concealment, deviations from intended interventions, measurement of the outcomes, and missing outcome data. Transitional discharge interventions may make little to no difference in service use (hospitalization) at short- and long-term follow-ups, but the evidence is very uncertain (RR 1.18, 95% CI 0.55 to 2.50; I2 = 54%; 4 studies, 462 participants; very low-certainty evidence). Transitional discharge intervention may increase the levels of functioning after discharge (clinically important change in general functioning) (SMD 0.95, 95% CI -0.06 to 1.97; I² = 95%; 4 studies, 437 participants; very low-certainty evidence) and may increase the proportion of participants who are satisfied with the intervention (clinically important change in satisfaction) (RR 1.96, 95% CI 1.37 to 2.80; 1 study, 76 participants; very low-certainty evidence), but for both outcomes the evidence is very uncertain. Transitional discharge intervention may make little to no difference in quality of life compared to treatment as usual (SMD 0.24, 95% CI -0.30 to 0.78; I² = 90%; 4 studies, 748 participants; very low-certainty evidence), but we are very uncertain. For direct costs, one study with 124 participants did not report full details and thus the results were inconclusive. AUTHORS' CONCLUSIONS: There is currently no clear evidence for or against implementing transitional discharge interventions for people with schizophrenia. Transitional discharge interventions may improve patient satisfaction and functionality, but this evidence is also very uncertain. For future research, it is important to improve the quality of the conduct and reporting of these trials, including using validated tools for measuring their outcomes.

ABSTRACT

Schizophrenia, a debilitating psychiatric disorder, has a long-term impact on social and occupational functioning. While negative symptoms, notably amotivation, are recognized as poor prognostic factors, the positive force of patient motivation (autonomous motivation) remains underexplored. This systematic review, guided by Self-Determination Theory (SDT), investigated the impact of motivation on clinical presentation, and treatment engagement and response in schizophrenia-spectrum disorders. Fifty-five independent studies (N = 6897), using 23 different motivation scales, met inclusion criteria. Results were categorized into cross-sectional and longitudinal correlates of autonomous motivation, and the effects of motivational interventions. Cross-sectionally, autonomous motivation was positively associated with social/occupational functioning, and negatively associated with negative and positive symptom severity. In longitudinal studies, baseline autonomous motivation predicted engagement in and response to social/occupational treatments, with mixed results in cognitive interventions. In the 16 randomized controlled trials (RCTs), the most common motivational interventions were individualized goal setting and goal attainment support, followed by increasing sense of competence by challenging defeatist beliefs, and enhancing relatedness by increasing contact time. Motivational interventions consistently increased autonomous motivation, treatment engagement and response. More studies are needed, particularly studies that monitor motivation during treatment: proximal assessments could facilitate the identification of treatment elements that impact motivation and engagement and inform treatment modifications to enhance the patient experience and improve treatment efficacy.
