Life engagement in people living with schizophrenia: predictors and correlates of patient life engagement in a large sample of people living in the community

Oral versus long-acting injectable antipsychotics in schizophrenia spectrum disorders: A systematic review of patients' subjective experiences

Schizophrenia spectrum disorders significantly impact daily functioning, with antipsychotic medications regarded as the gold standard treatment. However, their efficacy is often limited by side effects and adherence rates. Understanding patient perspectives and subjective experiences, particularly regarding oral versus long-acting injectable (LAI) antipsychotics, is crucial for improving medication outcomes and patient-tailored treatments. A systematic review of qualitative studies was conducted following the ENTREQ guidelines. Data were extracted from PubMed, Scopus, and PsycInfo, with thematic synthesis used to identify key themes in patient-reported experiences. Thirty-nine studies (1.477 patients) were included and analyzed, revealing three core themes: (1) perception and experience of medication, (2) social dynamics and influence, and (3) trust and communication with healthcare providers. Side effects and lack of information were often mentioned by patients. While LAI antipsychotics were linked to symptom stability and functional improvements, many patients lacked adequate information about their effects, contributing to adherence difficulties. Stigma and negative beliefs were common across both oral and LAI formulations, thus determining significant barriers to medication adherence. This review emphasizes that patients' experiences with antipsychotic medications are shaped by three key factors: the environment, the therapeutic relationship, and the drug itself. Two critical areas warrant particular attention: psychoeducation and stigma. Bridging psychoeducational gaps and addressing stigma could significantly enhance treatment adherence and outcomes. Additionally, greater emphasis on providing comprehensive and accurate information about antipsychotic treatment options is essential to support patient-centred care and informed decision-making.

Effects of brexpiprazole on patient life engagement in schizophrenia: post hoc analysis of Positive and Negative Syndrome Scale data

OBJECTIVE

Patients with schizophrenia value improved life engagement, a term that describes positive health aspects across emotional, physical, social, and cognitive domains. This post hoc analysis of clinical trial data aimed to investigate the effect of brexpiprazole on patient life engagement in schizophrenia over the short and long term.

METHODS

Data were pooled from three 6-week, randomized, double-blind, placebo-controlled clinical trials (ClinicalTrials.gov identifiers: NCT01396421, NCT01393613, NCT01810380; N = 1385) and two 52-week, open-label extension studies (NCT01397786, NCT01810783; N = 408) of brexpiprazole in adults with schizophrenia. Patient life engagement was measured using a subset of 14 Positive and Negative Syndrome Scale items (score range: 14 [best] to 98 [worst]) that has previously demonstrated content validity. Mean score changes and response rates (based on minimal clinically important difference estimates of ≥5 and ≥10 points) were calculated.

RESULTS

Greater improvement in patient life engagement from baseline to Week 6 was observed for brexpiprazole 2-4 mg/day (least squares mean [standard error] change: -8.3 [0.3]; n = 868) versus placebo (-5.7 [0.4]; n = 517), with a least squares mean difference of -2.58 (95% confidence interval: -3.57 to -1.58; p < 0.001; Cohen's d effect size: 0.28). These improvements were maintained over 58 weeks on brexpiprazole 1-4 mg/day (n = 399). At Week 6, response rates among patients treated with brexpiprazole versus placebo were 71.6% versus 58.0% (≥5-point improvement; p < 0.001) and 43.5% versus 32.8% (≥10-point improvement; p < 0.001). At Week 58 (n = 179), response rates among patients treated with brexpiprazole were 90.5% (≥5-point improvement) and 78.2% (≥10-point improvement).

CONCLUSION

Beyond its efficacy on psychotic symptoms, brexpiprazole has the potential to improve patient life engagement - an important patient-centered outcome in schizophrenia.

Assessment of patient life engagement in schizophrenia using items from the Positive and Negative Syndrome Scale

BACKGROUND

Improved patient life engagement is a meaningful treatment goal in schizophrenia that cannot be satisfactorily measured using existing tools. This research aimed to determine whether certain items from the Positive and Negative Syndrome Scale (PANSS) can assess patient life engagement in schizophrenia.

METHODS

Three approaches were used to identify PANSS items that reflect patient life engagement: (1) a panel discussion with expert psychiatrists (n = 4); (2) interviews with patients with schizophrenia (n = 20); and (3) a principal component analysis to explore clustering of items (n = 954 from three randomized controlled trials). Internal consistency was assessed by Cronbach's alpha and item-total correlations. A minimal clinically important difference (MCID) was determined by anchor- and distribution-based methods.

RESULTS

Expert psychiatrists identified 11 relevant items, and patients rated 13 items as "very relevant" to patient life engagement, most of which clustered in the principal component analysis. Considering all results, a composite set of 14 PANSS items that may be relevant to patient life engagement in schizophrenia was devised: P2, N1, N2, N3, N4, N5, N6, N7, G6, G7, G11, G13, G15, G16 (Cronbach's alpha, 0.84; item-total correlations, 0.35-0.56, indicating acceptable correlation with the underlying concept; exception: G6 [depression], 0.19). An MCID of 5 points (small/moderate improvement) or 10 points (large improvement) may be appropriate.

CONCLUSIONS

A subset of 14 PANSS items may be used to reflect patient life engagement in clinical practice/trials in schizophrenia, complementing the results of traditional psychiatric symptom scales with a patient-centered outcome that is relevant to real-world treatment goals.

The economic burden of schizophrenia spectrum disorders: clinical and functional correlates and predictors of direct costs. A retrospective longitudinal study

The economic burden of schizophrenia amounts for 1.5-3 % of healthcare expenses in developed countries, and ∼50 % derives from direct costs: 81 % of these are due to hospitalization, residential facilities and semi-residential facilities. Therefore, a better characterization of variables that influence direct costs represents a relevant issue. A total of 276 individuals with schizophrenia spectrum disorders receiving treatment from the Community Mental Health Centers of Brescia (Italy) were included in the study: for each participant socio-demographic, clinical and functional characteristics were assessed, and data related to the use of services in 2022 (then converted to costs) were collected. Regression analyses were performed to identify predictors of costs. A direct healthcare expenditure of 16477.23 (±32856.47) € per patient per year was identified. The main cost predictor was the PSP total score (p=0.005), followed by age of onset (p=0.020), and PANSS total score (p=0.033). Including PANSS sub-scales scores and PSP single items as potential predictors, the main predictor was the "socially useful activities" PSP item (p=0.002), followed by age of onset (p=0.011), and PANSS negative scale score (p=0.027). Our findings underline the need to implement rehabilitative intervention focused on the improvement of psychosocial functioning and negative symptoms, also to reduce healthcare expenses.

Is It Possible to Combine Non-Invasive Brain Stimulation and Evidence-Based Psychosocial Interventions in Schizophrenia? A Critical Review

In schizophrenia, it was suggested that an integrated and multimodal approach, combining pharmacological and non-pharmacological interventions, could improve functional outcomes and clinical features in patients living with schizophrenia (PLWS). Among these alternatives, evidence-based psychosocial interventions (EBPIs) and Non-Invasive Brain Stimulation (NIBS) represent feasible treatment options targeting the clinical features that are unmet needs of PLWS (especially negative and cognitive symptoms). As no clear evidence is available on the combination of these non-pharmacological approaches, this review aimed to collect the available literature on the combination of EBPIs and NIBS in the treatment of PLWS. We demonstrated that the field of combining EBPIs and NIBS in schizophrenia is in its infancy, as only 11 studies were reviewed. In fact, only a few trials, with divergent results, combined these non-pharmacological modalities; while emerging evidence is available on the combination of cognitive remediation and rTMS/iTBS, inconclusive results were obtained. Conversely, albeit preliminary, more solid findings are available on the combination of HF-rTMS and family intervention. Moreover, despite the fact that cognitive activation could not be considered an EBPI, promising results are available in combination with tDCS to improve the working memory domain. To overcome these limitations, we considered several methodological issues to promote research in this field.

Psychometric validation of the Spanish version of the life engagement test: Assessing validity and reliability

The Life Engagement Test (LET) consists of a fast instrument to measure the extent to which individuals identify and participate in valued activities and, therefore, engage in life. It is also a fundamental component of psychological well-being. This study aims to validate the Spanish version of the Life Engagement Test (LET-ES). First, the LET was translated using back-translation methodology, after which a pilot study was tested on 41 individuals. Then, the final version of the LET-ES was administered to a convenience sample of 436 Spanish participants (67,7 % female; 59,6 % aged 18 to 35 years old) to assess its reliability and validity. A subset of 138 participants (70,5 % female, 59,7 % aged 18 to 35 years old) completed a retest. Confirmatory factor analysis, reliability analysis (Cronbach's alpha, McDonald's omega), test-retest reliability (intraclass correlation coefficient), measurement invariance across gender and age, as well as convergent validity analyses were conducted. Results confirmed the one-factor structure of the LET-ES. Cronbach's alpha, McDonald's omega, and test-retest analysis yielded satisfactory reliability of the scale. Measurement invariance was established for gender, but not for age. Finally, convergent validity was supported by significant and positive correlations between the LET-ES scores and psychological well-being variables (i.e., purpose in life, satisfaction with life), and significant negative correlations between the LET-ES and psychological discomfort variables (i.e. stress, anxiety, depression). In conclusion, the Spanish version of the LET is a valid and reliable measure to assess life engagement among the Spanish population.

Definition, assessment and treatment of cognitive impairment associated with schizophrenia: expert opinion and practical recommendations

A considerable proportion of patients with schizophrenia perform below population norms on standardized neuropsychological tests, and the performance of those performing within normal range is lower than predicted based on parental education. Cognitive impairment predates the onset of psychosis, is observed during symptom remission and in non-affected first-degree relatives of patients. At the present time, cognitive deficits are regarded as key features of schizophrenia, important determinants of poor psychosocial outcome and targets for both pharmacological and non-pharmacological treatment strategies. A group of eight key opinion leaders reviewed and discussed latest advances in scientific research and current good clinical practices on assessment, management, and treatment of CIAS. In the present paper they summarize the current evidence, identify main gaps between current knowledge and mental health services clinical practice, and provide practical recommendations to reduce the gap.

Functioning Management and Recovery, a psychoeducational intervention for psychiatric residential facilities: a multicenter follow-up study

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.

Treatment of Cognitive Impairment Associated with Schizophrenia Spectrum Disorders: New Evidence, Challenges, and Future Perspectives

Cognitive impairment associated with schizophrenia (CIAS) represents one of the core features of the disorder and has a significant impact on functional and rehabilitation outcomes of people living with schizophrenia spectrum disorders (SSD). The aim of this critical review is to highlight the most recent evidence on effective treatments available for CIAS, to discuss the current challenges in this field, and to present future perspectives that may help to overcome them. Concerning psychopharmacological approaches, among the most indicated strategies for the management and prevention of CIAS is to favor second-generation antipsychotic medications and avoid long-term and high-dose treatments with anticholinergic medications and benzodiazepines. Moreover, non-pharmacological approaches such as cognitive remediation and physical exercise-based programs represent evidence-based interventions in the treatment of CIAS that have shown reliable evidence of effectiveness on both cognitive and functional outcomes. These treatments, however, are still delivered to people accessing mental health services with a diagnosis of CIAS in an uneven manner, even in high-income countries. Academic and clinical partnership and collaboration, as well as advocacy from service users, families, carers, and stakeholders' organizations could help to reduce the bench to bedside gap in the treatment of CIAS. Future perspectives include the development of novel pharmacological agents that could be effective in the treatment of CIAS, the implementation of novel technologies such as telemedicine and virtual reality in the delivery of evidence-based interventions to improve accessibility and engagement, and further research in the field of non-invasive brain stimulation.

Effects of anhedonia on health-related quality of life and functional outcomes in major depressive disorder: A systematic review and meta-analysis

BACKGROUND

Major depressive disorder (MDD) is a heterogeneous group of mood disorders. A prominent symptom domain is anhedonia narrowly defined as a loss of interest and ability to experience pleasure. Anhedonia is associated with depressive symptom severity, MDD prognosis, and suicidality. We perform a systematic review and meta-analysis of extant literature investigating the effects of anhedonia on health-related quality of life (HRQoL) and functional outcomes in persons with MDD.

METHODS

A literature search was conducted on PubMed, OVID databases, and SCOPUS for published articles from inception to November 2023, reporting on anhedonia and patient-reported outcomes in persons with MDD. The reported correlation coefficients between anhedonia and self-reported measures of both HRQoL and functional outcomes were pooled using a random effects model.

RESULTS

We identified 20 studies that investigated anhedonia with HRQoL and/or functional outcomes in MDD. Anhedonia as measured by the Snaith-Hamilton Pleasure Scale (SHAPS) scores had a statistically significant correlation with patient-reported HRQoL (r = -0.41 [95 % CI = -0.60, -0.18]) and functional impairment (r = 0.39 [95 % CI = 0.22, 0.54]).

LIMITATIONS

These preliminary results primarily investigate correlations with consummatory anhedonia and do not distinguish differences in anticipatory anhedonia, reward valuation or reward learning; therefore, these results require replication.

CONCLUSIONS

Persons with MDD experiencing symptoms of anhedonia are more likely to have worse prognosis including physical, psychological, and social functioning deficits. Anhedonia serves as an important predictor and target for future therapeutic and preventative tools in persons with MDD.

Evidence-based psychosocial interventions in schizophrenia: a critical review

PURPOSE OF REVIEW

Schizophrenia Spectrum Disorders (SSD) are severe conditions that frequently produce significant impairment in cognitive performance, social skills and psychosocial functioning. As pharmacological treatment alone often provides only limited improvements on these outcomes, several psychosocial interventions are employed in psychiatric rehabilitation practice to improve of real-world outcomes of people living with SSD: the present review aims to provide a critical overview of these treatments, focusing on those that show consistent evidence of effectiveness.

RECENT FINDINGS

Several recent systematic reviews and meta-analyses have investigated in detail the acceptability, the effectiveness on several specific outcomes and moderators of response of different psychosocial interventions, and several individual studies have provided novel insight on their implementation and combination in rehabilitation practice.

SUMMARY

Cognitive remediation, metacognitive training, social skills training, psychoeducation, family interventions, cognitive behavioral therapy, physical exercise and lifestyle interventions, supported employment and some other interventions can be fully considered as evidence-based treatments in SSD. Psychosocial interventions could be of particular usefulness in the context of early intervention services. Future research should focus on developing newer interventions, on better understanding the barriers and the facilitators of their implementation in clinical practice, and exploring the opportunities provided by novel technologies.

Pharmacological Treatment of Cognitive Impairment Associated With Schizophrenia: State of the Art and Future Perspectives

Cognitive Impairment Associated with Schizophrenia (CIAS) represents one of the core dimensions of Schizophrenia Spectrum Disorders (SSD), with an important negative impact on real-world functional outcomes of people living with SSD. Treatment of CIAS represents a therapeutic goal of considerable importance, and while cognition-oriented evidence-based psychosocial interventions are available, effective pharmacological treatment could represent a game-changer in the lives of people with SSD. The present critical review reports and discusses the evidence regarding the effects of several pharmacological agents that are available in clinical practice or are under study, commenting on both current and future perspectives of CIAS treatment. In particular, the effects on CIAS of antipsychotic medications, anticholinergic medications, benzodiazepines, which are currently commonly used in the treatment of SSD, and of iclepertin, d-serine, luvadaxistat, xanomeline-trospium, ulotaront, anti-inflammatory molecules, and oxytocin, which are undergoing regulatory trials or can be considered as experimental agents, will be reported and discussed. Currently, available pharmacological agents do not appear to provide substantial benefits on CIAS, but accurate management of antipsychotic medications and avoiding treatments that can further exacerbate CIAS represent important strategies. Some molecules that are currently being investigated in Phase 2 and Phase 3 trials have provided very promising preliminary results, but more information is currently required to assess their effectiveness in real-world contexts and to provide clear recommendations regarding their use in clinical practice. The results of ongoing and future studies will reveal whether any of these molecules represents the awaited pharmacological game-changer in the treatment of CIAS.
