Cognitive behavior therapy in early psychosis with a focus on depression and low self-esteem: A randomized controlled trial

Self-reported suicidal ideation among individuals with first episode psychosis and healthy controls: Findings from the international multicentre EU-GEI study

INTRODUCTION

Suicidal ideation is common among individuals with first episode psychosis (FEP), with prevalence estimates up to 56.5 %. Despite its high prevalence, relatively little is known about how sociodemographic, clinical and/or developmental characteristics contribute to the experience of suicidal ideation in individuals with FEP.

METHODS

In this cross-sectional study (FEP n = 551 and controls n = 857), univariate logistic regression analyses were performed to study the associations of sociodemographic, clinical, and developmental factors with suicidal ideation in individuals with FEP as well as controls. Suicidal ideation was assessed using the Community Assessment of Psychic Experiences (CAPE). In addition, multivariate logistic regression analyses were conducted based on a stepwise approach.

RESULTS

In FEP, only depressive symptoms remained significantly associated with suicidal ideation when all correlates were integrated into one model. In the multivariate model in controls, depressive symptoms, positive symptoms, and traumatic childhood experiences were significantly associated with suicidal ideation.

CONCLUSIONS

This study showed that depressive symptoms are an important factor relating to suicidal ideation in individuals with FEP, over and above other clinical, sociodemographic, and developmental factors. This underscores the relevance of screening for suicidal ideation in individuals with FEP, and highlights the need for a better understanding of the diagnostic uncertainty and course of mood symptoms in early psychosis.

LIMITATIONS

Cross-sectional study design, self-reported questionnaires.

Individuals with genetic high-risk for psychosis experience impaired coping styles compared with healthy controls

BACKGROUND

Individuals with schizophrenia tend to have negative coping styles and low levels of self-esteem, but it is unclear whether coping styles and self-esteem levels are altered in people in the prodromal phase of psychosis.

AIMS

The study was designed to assess the role of coping style and self-esteem in the context of different phases of schizophrenia.

METHODS

Recurrent Schizophrenia (ReSch), first-episode schizophrenia patients (FEP), genetic-high risk for psychosis (GHR) patients, and healthy controls (HC) (40 per group) were subjected to in-person clinical interviews. The results of these interviews were then used to gauge coping style and self-esteem using the Coping Styles Questionnaire (CSQ) and the Rosenberg's Self-Esteem Scale (RSES). Data were analyzed through ANCOVAs and logistic regression analyses.

RESULTS

The results found that positive coping style (CSQ problem-solving and CSQ seeking for help) generally decline with progression through the HC, GHR, and FEP groups, while negative coping style (CSQ fantasy, CSQ repression and CSQ self-blame) generally increase with progression through the HC, GHR, and FEP groups (except that GHR group was slightly lower than HC group in CSQ self-blame). Results for members of ReSch group were in line with those of members of the FEP group in coping style. At the level of self-esteem, the GHR group was similar to the HC group and significantly higher than the FEP group and the ReSch group. Logistic regression analyses indicated that GHR group patients exhibited increased negative coping styles (CSQ fantasy) relative to members of the HC group, but had greater Positive coping style (CSQ problem-solving) than did members of the FEP group.

DISCUSSION

These findings suggest that both GHR individuals experience impaired negative coping styles which expands the understanding of the psychological characteristics of the prodromal group. Further explorations are warranted to develop optimal psychosocial interventions.

Cognitive behavioural therapy added to standard care for first-episode and recent-onset psychosis

BACKGROUND

Cognitive behavioural therapy (CBT) can be effective in the general population of people with schizophrenia. It is still unclear whether CBT can be effectively used in the population of people with a first-episode or recent-onset psychosis.

OBJECTIVES

To assess the effects of adding cognitive behavioural therapy to standard care for people with a first-episode or recent-onset psychosis.

SEARCH METHODS

We conducted a systematic search on 6 March 2022 in the Cochrane Schizophrenia Group's Study-Based Register of Trials, which is based on CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, PubMed, ClinicalTrials.gov, ISRCTN, and WHO ICTRP.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing CBT added to standard care vs standard care in first-episode or recent-onset psychosis, in patients of any age.

DATA COLLECTION AND ANALYSIS

Two review authors (amongst SFM, CC, LK and IB) independently screened references for inclusion, extracted data from eligible studies and assessed the risk of bias using RoB2. Study authors were contacted for missing data and additional information. Our primary outcome was general mental state measured on a validated rating scale. Secondary outcomes included other specific measures of mental state, global state, relapse, admission to hospital, functioning, leaving the study early, cognition, quality of life, satisfaction with care, self-injurious or aggressive behaviour, adverse events, and mortality.

MAIN RESULTS

We included 28 studies, of which 26 provided data on 2407 participants (average age 24 years). The mean sample size in the included studies was 92 participants (ranging from 19 to 444) and duration ranged between 26 and 52 weeks. When looking at the results at combined time points (mainly up to one year after start of the intervention), CBT added to standard care was associated with a greater reduction in overall symptoms of schizophrenia (standardised mean difference (SMD) -0.27, 95% confidence interval (CI) -0.47 to -0.08, 20 RCTs, n = 1508, I2 = 68%, substantial heterogeneity, low certainty of the evidence), and also with a greater reduction in positive (SMD -0.22, 95% CI -0.38 to -0.06, 22 RCTs, n = 1565, I² = 52%, moderate heterogeneity), negative (SMD -0.20, 95% CI -0.30 to -0.11, 22 RCTs, n = 1651, I² = 0%) and depressive symptoms (SMD -0.13, 95% CI -0.24 to -0.01, 18 RCTs, n = 1182, I² = 0%) than control. CBT added to standard care was also associated with a greater improvement in the global state (SMD -0.34, 95% CI -0.67 to -0.01, 4 RCTs, n = 329, I² = 47%, moderate heterogeneity) and in functioning (SMD -0.23, 95% CI -0.42 to -0.05, 18 RCTs, n = 1241, I² = 53%, moderate heterogeneity, moderate certainty of the evidence) than control. We did not find a difference between CBT added to standard care and control in terms of number of participants with relapse (relative risk (RR) 0.82, 95% CI 0.57 to 1.18, 7 RCTs, n = 693, I² = 48%, low certainty of the evidence), leaving the study early for any reason (RR 0.87, 95% CI 0.72 to 1.05, 25 RCTs, n = 2242, I² = 12%, moderate certainty of the evidence), adverse events (RR 1.29, 95% CI 0.85 to 1.97, 1 RCT, n = 43, very low certainty of the evidence) and the other investigated outcomes.

AUTHORS' CONCLUSIONS

This review synthesised the latest evidence on CBT added to standard care for people with a first-episode or recent-onset psychosis. The evidence identified by this review suggests that people with a first-episode or recent-onset psychosis may benefit from CBT additionally to standard care for multiple outcomes (overall, positive, negative and depressive symptoms of schizophrenia, global state and functioning). Future studies should better define this population, for which often heterogeneous definitions are used.

Depression severity mediates stigma and quality of life in clinically stable people with schizophrenia in rural China

BACKGROUND

Depressive symptoms associated with schizophrenia are closely related to stigma and quality of life(QOL). There is, however, no thorough research on the connection between the three. This study sought to investigate the possible factors influencing depressive symptoms in people with schizophrenia (PWS) in rural Chaohu, China, and to further explore the role of depression severity in stigma and lifestyle quality.

METHODS

Eight hundred twenty-one schizophrenia patients accomplished the entire scale, including the 9-item Patient Health Questionnaire (PHQ-9), the Social Impact Scale (SIS), and the World Health Organization on Quality of Life Brief Scale(WHOQOL-BREF). A straightforward mediation model was employed to determine if the intensity of the depression could act as a mediator between stigma and QOL.

RESULTS

Two hundred seventy-nine schizophrenia patients (34%) had depressive symptoms (PHQ ≥ 10), and 542 patients (66%) did not (PHQ < 10). Logistic regression showed that marital status, job status, physical exercise, standard of living, and stigma contributed to the depressed symptoms of schizophrenia. Depression severity partially mediated the effect between stigma and QOL, with a mediating effect of 48.3%.

CONCLUSIONS

This study discovered a significant incidence of depressed symptoms associated with schizophrenia, with depression severity serving as a mediator variable connecting stigma and QOL and partially moderating the association.

The application of cognitive behavioral therapy in patients with schizophrenia: A review

The aim of this review is to explore the clinical nursing application of cognitive behavioral therapy (CBT) in patients with schizophrenia. A literature search was conducted using the CINAHL and MEDLINE databases. The database search occurred during the month of December 2022. This article comprehensively summarizes the theoretical basis of CBT in improving schizophrenia in clinical nursing, its application in managing symptoms and improving social function, as well as research progress in this field. There are still inconsistencies in the research results on CBT, but overall, psychological intervention combined with drug treatment is more effective than conventional treatment alone. If social function training can be added at the same time, it is believed that it will have better effects on clinical treatment and can maintain long-lasting effectiveness. Only in this way can patients truly understand and recognize the disease, improve treatment compliance, and ultimately achieve the goal of improving prognosis and quality of life.

Association of loneliness with suicide risk and depression in individuals with schizophrenia: moderating effects of self-esteem and perceived support from families and friends

Loneliness is prevalent among individuals with mental illnesses. This cross-sectional survey study examined the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression in individuals with schizophrenia. In total, 300 participants (267 with schizophrenia and 33 with schizoaffective disorder) completed the University of California, Los Angeles, Loneliness Scale (Version 3); suicide module of the Mini International Neuropsychiatric Interview; Center for Epidemiologic Studies Depression Scale; Family and Friend Adaptability, Partnership, Growth, Affection, and Resolve Index; and Rosenberg Self-Esteem Scale. Moderation analysis was performed to examine the moderating effects of self-esteem and perceived support from families and friends on the association of loneliness with suicide risk and depression. The results found that self-esteem was significantly associated with a reduced magnitude of depression in participants with loneliness. In addition, perceived support from friends was significantly associated with a reduced magnitude of suicide risk in participants with loneliness. Our findings indicate the importance of intervention programs that strengthen support from friends and self-esteem in reducing suicide risk and depression among lonely individuals with schizophrenia.

Effectiveness of group metacognitive training and cognitive-behavioural therapy in a transdiagnostic manner for young patients with psychotic and non-psychotic disorders

AIM

To investigate group metacognitive training and cognitive-behavioural therapy (MCT/CBT) prospectively in a young population with various psychiatric disorders, including psychotic and mood disorders.

METHODS

This was a prospective study to investigate the effectiveness of group MCT/CBT on quality of life, psychotic symptoms, depression, self-esteem, perceived stress, social function and social cognition. The objective measures included the Positive and Negative Syndrome Scale (PANSS), clinical global impression (CGI), personal and social performance scale for social functioning, a computerized continuous performance test for sustained attention and a computerized emotional recognition test for social cognition. Self-report measures administered included the Subjective Well-being under Neuroleptics for quality of life, Ambiguous Intentions Hostility Questionnaire for suspiciousness, Drug Attitude Inventory, Beck Depression Inventory, Perceived Stress Scale, Brief Resilience Scale, Rosenberg Self-esteem Scale and visual analogue scale for the EQ-5D.

RESULTS

Among 110 young patients with early psychosis and mood disorders who participated, 82 (74.5%) completed the study. Social functioning, quality of life, self-esteem, resilience, depression, suspiciousness, social cognition, sustained attention and scores on the PANSS and CGI improved significantly after completing group MCT/CBT. Perceived stress, resilience and suspiciousness improved significantly only in participants with a non-psychotic disorder. Improvements in subjective well-being of the participants were associated with increases in self-esteem and resilience and decreases in depression and perceived stress.

CONCLUSIONS

Our study showed that group transdiagnostic MCT/CBT for young patients with mental illness improved subjective wellbeing, self-esteem, resilience, social cognition and social functioning and significantly diminished suspiciousness, perceived stress and depression.

Association between Self-Stigma and Suicide Risk in Individuals with Schizophrenia: Moderating Effects of Self-Esteem and Perceived Support from Friends

This cross-sectional study assessed the moderating effects of self-esteem and perceived support from friends on the association between self-stigma and suicide risk in individuals with schizophrenia. We included 300 participants (267 with schizophrenia and 33 with schizoaffective disorder). Suicide risk was assessed using items adopted from the suicide module of the Mini-International Neuropsychiatric Interview; self-stigma was assessed using the Self-Stigma Scale-Short; perceived support from friends was assessed using the Friend Adaptation, Partnership, Growth, Affection, and Resolve Index; and self-esteem was assessed using the Rosenberg Self-Esteem Scale. A moderation analysis was performed to examine the moderating effects of self-esteem and perceived support from friends on the association between self-stigma and suicide risk. The results indicated that self-stigma was positively associated with suicide risk after the effects of other factors were controlled for. Both perceived support from friends and self-esteem significantly reduced the magnitude of suicide risk in participants with self-stigma. Our findings highlight the value of interventions geared toward ameliorating self-stigma and enhancing self-esteem in order to reduce suicide risk in individuals with schizophrenia.

The Role of Cognitive Behavioral Therapy in the Management of Psychosis

Cognitive behavioral therapy for psychosis (CBTp) as a modality of treatment is gaining attention. A number of authors have reported their experiences, including challenges, in administering CBTp for psychotic patients. With CBTp still evolving a lot more research is ongoing to fine-tune its benefits while mitigating the limitations to its use. The objectives of this review are to determine the role of CBTp in the overall improvement of a patient's quality of life, ascertain the number of hospitalizations with acute symptoms after the start of CBTp; and address the common drawbacks to CBTp in the management of psychosis. It was found that cognitive behavioral therapy (CBT) use can prevent the first episode of psychosis in ultra-high risk (UHR) and is effective in improving depression, self-esteem, and psychological well-being. Its use was associated with positive changes in thinking and mood, and sleep quality leading to improved everyday life. Patients who underwent CBT had fewer hospitalizations with a higher number of voluntary hospitalizations as compared to patients with usual care, who underwent a higher number of involuntary hospitalizations. Drawbacks included cost-ineffectiveness and resource limitation.

Cognitive-behavioral group therapy in major depressive disorder with focus on self-esteem and optimism: an interventional study

BACKGROUND

Major depressive disorder is a common psychological condition that can lead to negative individual and social consequences, the management of which is very important in treating the patients. The present study aimed to determine the effect of cognitive-behavioral group therapy on self-esteem and optimism in patients with major depressive disorder.

METHODS

This is a single-blinded, randomized controlled trial in which a total of 64 patients with major depressive disorder were recruited using convenience sampling and then randomly assigned to two groups of Cognitive-Behavioral Group Therapy (CBGT) and Treatment-As-Usual (TAU). Data collection tools consisted of a demographic questionnaire, the Rosenberg Self-Esteem Scale (RSES), and the Revised Life Orientation Test (LOT-R). In the pretest stage, participants in both groups completed the above questionnaires before the intervention. Patients in the CBGT group received eight 90-min sessions of cognitive-behavioral therapy during four weeks (two sessions a week). Then participants re-completed RSES and LOT-R immediately, three months, and six months after the intervention. Data were analyzed with SPSS software version 16.0 using chi-squared test, independent-samples t-test, and repeated measures Analysis of Variance. The significance level (p-value) was considered to be less than 0.05.

RESULTS

It was indicated that there was a statistically significant difference in the mean scores of self-esteem and optimism between the two groups immediately, three months, and six months after the intervention (p < .05). The mean scores of self-esteem and optimism in the CBGT group increased significantly after the intervention compared to before it, although these scores gradually decreased over the three measurement time points after the intervention.

CONCLUSIONS

Based upon the results, it was concluded that the level of optimism and self-esteem increased significantly in the CBGT group after the intervention, although the levels of the above variables dropped again in the long run after the intervention due to the discontinuity of CBGT sessions. Therefore, it is necessary to take particular measures to regularly hold the sessions of CBGT for patients with major depressive disorder.

Feasibility and efficacy of an acceptance and mindfulness-based group intervention for young people with early psychosis (Feel-Good group)

BACKGROUND

Over the last decade, researchers have sought for alternative interventions that have better treatment effects than Cognitive Behavioral Therapy (CBT) when treating psychotic symptoms. Mindfulness-based interventions have been a proposed alternative to CBT, yet research regarding its feasibility, acceptance and effectiveness is lacking when treating individuals with early psychosis in inpatient settings.

OBJECTIVE

Before conducting a large-scale randomized-controlled trial (RCT), this pilot study evaluated the feasibility and the potential efficacy of a mindfulness-based inpatient group intervention that targets emotion regulation in patients with early psychosis, and thus indirectly improving psychotic symptoms.

METHODS

A pre-post study was performed. Thirty-six patients with early psychosis treated at the specialized inpatient treatment "Frühinterventions- und Therapiezentrum; FRITZ" (early intervention and therapy center) received eight group therapy sessions. Assessments were performed at baseline, after 8 weeks post treatment and at follow-up after 16 weeks.

RESULTS

Rates of patients who participated in the study suggests that a mindfulness-based group therapy is highly accepted and feasible for patients with early psychosis being treated in an inpatient ward. Friedman analyses revealed significant changes in the primary outcomes of emotional goal attainment (Goal 1: W = 0.79; Goal 2: W = 0.71) and psychotic symptoms (PANSS-T: W = 0.74). Significant, albeit small, effect sizes were found in patients' self-perception of emotion regulation skills (ERSQ: W = 0.23).

DISCUSSION

We found favorable findings regarding the feasibility and acceptance of the Feel-Good mindfulness-based intervention. Results of the study provide a basis for an estimation of an adequate sample size for a fully powered RCT that needs to be conducted to test whether Feel-Good is effective in the inpatient treatment of psychotic symptoms for individuals with early psychosis.

Cognitive behavioral group treatment for low self-esteem in psychosis: a proof of concept study

BACKGROUND

Patients with a psychotic disorder often suffer from low self-esteem, which has been related to higher suicidal risk, poor quality of life and, the maintenance of psychotic and depression symptoms. However, intervention studies are scarce and reported interventions concern individual therapies provided by highly educated psychologists. Both the individual setting and the required qualifications of the therapist may contribute to a low level of availability of an intervention. Therefore we aimed to investigate the efficacy of an easily accessible psychological group treatment targeting self-esteem in patients with a psychotic disorder.

METHODS

Thirty patients with a psychotic disorder were included in this pilot study. All participants received nine weekly group sessions of 90 min. The therapy was offered in groups of six to eight patients and was provided by a psychiatry nurse and a graduate psychologist. To assess self-esteem the Rosenberg Self-esteem Scale and the Self-Esteem Rating Scale were used, to measure depression symptoms the Beck Depression Inventory-II was administered. Questionnaires were completed at baseline and post-treatment.

RESULTS

Twenty-seven patients (90%) completed treatment. At post-treatment, self-esteem was significantly increased and depression symptoms were significantly decreased compared to baseline.

DISCUSSION

This pilot study demonstrates the feasibility and treatment potential of a self-esteem group treatment provided by a psychiatry nurse and graduate psychologist in a patient population that receives little psychological treatment. Results suggest that this easily accessible intervention may be effective in improving self-esteem and reducing depression symptoms.

Individual psychotherapy can reduce suicidal ideation in first episode psychosis: Further findings from the 2-year follow-up of the 'Parma Early Psychosis' programme

INTRODUCTION

Suicidal thinking is relevant in patients with First Episode Psychosis (FEP). However, longitudinal studies specifically examining treatment response for suicidal ideation in FEP are still relatively scarce, especially with long-term design and in real-world clinical settings. The aims of this research were (A) to longitudinally assess suicidal thoughts in people with FEP along a 2-year follow-up period and (B) to overtime investigate any significant association of suicidal ideation levels with the specific treatment components of an 'Early Intervention in Psychosis' (EIP) protocol along the 2 years of follow-up.

METHODS

At entry, 232 FEP participants (aged 12-35 years) completed the Brief Psychiatric Rating Scale (BPRS), including a 'Suicidality' item subscore. Multiple linear regression analysis was then performed.

RESULTS

Across the follow-up, FEP subjects showed a relevant decrease in suicidal thinking levels overtime. This was specifically predicted by the total number of individual psychotherapy sessions offered within the 2-year EIP protocol and antidepressant dose (at least as regards the first year of our intervention).

CONCLUSION

Suicidal ideation is clinically relevant in FEP but seems to improve overtime together with the provision of specific, patient-tailored and integrated EIP treatments, especially individual psychotherapy.

G-estimation of causal pathways in vocational rehabilitation for adults with psychotic disorders - a secondary analysis of a randomized trial

BACKGROUND

Vocational rehabilitation (VR) has increasingly become an important intervention targeting poor occupational functioning in schizophrenia. The Norwegian Job Management Program (JUMP), sought to enhance occupational outcomes by augmenting VR with either cognitive behavioral therapy (CBT) techniques aiming to improve psychotic symptoms or cognitive remediation (CR) aiming to improve cognition. CBT is standard treatment in schizophrenia, but recent meta-analyses question the effect of CBT on negative psychotic symptoms. It is of interest to study the causal role of psychotic symptoms and cognitive functioning on occupational functioning.

METHODS

Data from the JUMP VR - program, was reanalyzed with a causal inference method to assess the causal effects of reduced symptoms / improved neurocognitive functioning on occupational functioning measured by number of working hours per week. Participants (N = 131) had been randomized to either VR + CBT (N = 68) or VR + CR (N = 63). Large improvements in number of working hours were demonstrated in both intervention groups (nonsignificant group difference). G-estimation was used to assess the strength and nature of the causal effects, adjusted for time-varying confounding and selection - bias from loss to follow-up.

RESULTS

Significant causal effects of reduction in each of four dimensions of symptoms and improved neurocognition respectively, on number of working hours were found (separate models). The effect of negative symptoms was the strongest and increased in magnitude during the whole observation period, while the effect of two other symptoms and neurocognition was constant. Adjusted for confounding (including potential feedback), the causal effect of a hypothetical change in negative symptoms equal to the average improvement in the CBT group corresponded to an increase in working hours of 3.2 h per week (95% CI: 1.11, 5.35).

CONCLUSION

High performance of g-estimation in a small psychiatric data set with few repeated measures and time-varying confounding and effects, was demonstrated. Augmented vocational rehabilitation showed causal effects of intervention targets with the strongest and increasing effect from negative symptoms on number of working hours. Combination of therapy and activation (indirect and direct approach) might explain improvement in both cognition and negative symptoms, and shed some light on effective ingredients for improved treatment of negative symptoms.
