Early maladaptive schemas in patients with schizophrenia and non-patients with high and low schizotypal traits and their differences based on depression severity

Core beliefs in psychosis: a systematic review and meta-analysis

Increasing interest is growing for the identification of psychological mechanisms to account for the influence of trauma on psychosis, with core beliefs being proposed as a putative mediator to account for this relationship. A systematic review (n = 79 studies) was conducted to summarise the existing evidence base regarding the role of core beliefs/schemas in psychosis, Clinical High-Risk (CHR), and non-clinical samples with Psychotic-Like Experiences (PLEs). Compared to Healthy Controls (HCs), individuals with psychosis experiencing Auditory Hallucinations or Persecutory Delusions had significantly higher scores for negative self and negative other-beliefs and significantly lower scores for positive self and positive other-beliefs. This pattern of core beliefs was also observed for CHR individuals. In contrast, the core belief profile for grandiose delusions was in the opposite direction: higher positive self and positive other-beliefs and lower negative self-beliefs. In non-clinical samples, several factors mediated the relationship between Traumatic Life Events (TLEs) and PLEs, such as greater perceived stress, dissociation, external locus of control, and negative self and negative other-beliefs. Compared to HCs, meta-analyses revealed statistically significant large effects for negative self and negative other-beliefs in Schizophrenia. In CHR, statistically significant large and moderate effects were found for negative self and negative other-beliefs, respectively, along with a moderate negative effect for positive self-beliefs. Core beliefs were found to play a significant role in the development and maintenance of positive symptoms of psychosis. The development of psychosocial interventions that explicitly target negative self and other-beliefs, whilst also enhancing positive self-beliefs are warranted and would innovate CBTp practices.

Self-Reported Cognitive Bias in Psychosis: Further Validation of the Cognitive Biases Questionnaire for Psychosis (CBQ-P) and the Davos Assessment of Cognitive Biases (DACOBS) in a Large Iranian Clinical and Non-Clinical Sample

OBJECTIVE

Various factor structures have been suggested for the Davos Assessment of Cognitive Biases (DACOBS) and the Cognitive Biases Questionnaire for Psychosis (CBQ-P), assessing cognitive bias, necessitating additional validation in diverse languages to enhance the validity of the scales.

METHOD

Persian versions of these scales were validated within an Iranian cohort comprising 1719 individuals: patients with schizophrenia (n = 334) and major depressive disorder (MDD; n = 346) and a non-clinical group (n = 1039). The participants completed both self-report and clinician-administered assessments.

RESULTS

The 18-item DACOBS version, comprising four factors, and the single-factor structure of the CBQ-P exhibited the optimal model fit, with confirmed reliability. Both scales showed significant correlations with constructs such as paranoid ideation, social cognition, schizotypal personality and positive symptoms. Additionally, the scales differentiated patients with schizophrenia and individuals at high risk for psychosis from those at low risk or patients with MDD. The CBQ-P and certain subscales of the DACOBS predicted susceptibility to psychosis, positive symptoms and psychosis-related manifestations.

CONCLUSIONS

The research highlights the validity and reliability of the Persian adaptations of the 18-item DACOBS and the CBQ-P for evaluating cognitive bias in individuals diagnosed with schizophrenia and for identifying individuals at an elevated risk for psychosis.

Relationships between childhood trauma and dimensional schizotypy: A network analysis and replication

OBJECTIVES

Childhood trauma (CT) has been found to increase the risk of developing schizophrenia and other psychiatric disorders. Little is known regarding the complex interplay between CT, subclinical psychotic, and affective symptoms in the general population. This cross-sectional study adopted network analysis to examine such a complex relationship. We hypothesized that CT would show strong connections with schizotypy dimensions, and the high schizotypy subgroup would show a network with higher global strength compared with the low schizotypy subgroup.

METHODS

A total of 1813 college students completed a set of self-report questionnaires measuring CT, schizotypal features, bipolar traits, and depressive symptoms. The subscales of these questionnaires were used as nodes, and the partial correlations between nodes were used as edges to construct a network. Network Comparison Tests were used to investigate the differences between participants with high schizotypy and low schizotypy. An independent sample (n = 427) was used to examine the replicability of the results.

RESULTS

Findings from the main dataset showed that CT was closely connected with schizotypy and motivation, after controlling for the inter-relationships between all nodes in the network. Relative to the low schizotypy subgroup, the network of the high schizotypy subgroup showed higher global strength. The two subgroups did not differ in network structure. Network analysis using the replication dataset showed comparable global strength and network structure.

CONCLUSIONS

Our findings support specific links between CT and schizotypy dimensions in healthy youth populations, and such links appear to become stronger in those with high schizotypy.

Effect of Animal-Assisted Therapy (AAT) on Social Interaction and Quality of Life in Patients with Schizophrenia during the COVID-19 Pandemic: An Experimental Study

PURPOSE

Most patients with schizophrenia exhibit low willingness to return to society because of negative social experiences. The COVID-19 pandemic led to severe social isolation for schizophrenia patients. However, animal-assisted therapy (AAT) can improve individuals' empathy, social functions, and quality of life. The study aimed to evaluate the effectiveness of AAT in improving social interactions and quality of life in patients with chronic schizophrenia during the COVID-19 pandemic.

METHODS

An experimental study was conducted, with six institutions for psychiatric rehabilitation in Taiwan as the case institutions. Patients in these institutions were randomly allocated to the experimental group, which received 60 minutes of AAT once a week for 12 weeks, or the control group, which engaged in routine discussion groups and watched short films about animals. Comparisons between the two groups were made before and after the intervention on social function, social adaptive function, and quality of life. Data were collected before the intervention (T1), immediately after the intervention (T2), and 3 months after the intervention (T3).

RESULTS

Comparison between groups showed that social functioning was significantly higher in the experimental group than in the control group at T2. However, there was no sign of improvement in social adaptive functions of the experimental group. The experimental group exhibited significantly higher quality of life than the control group at T2 and T3.

CONCLUSIONS

There was an impact of COVID-19 on the studied effects. AAT improved social functioning and quality of life in patients with chronic schizophrenia. The effect on quality of life lasted only up to 3 months after the intervention. AAT should be promoted for use as a community-based rehabilitation tool in patients with chronic schizophrenia.

Early Maladaptive Schemas and Mental Disorders in Adulthood: a Systematic Review and Meta-analysis

Early maladaptive schemas (EMSs) are broad and pervasive themes regarding oneself and one’s relationships with others originating from adverse childhood experiences. Although the concept of EMSs was initially developed for the treatment of personality disorders, the associations of EMSs with a variety of other mental disorders have been investigated. The goal of the present study was to summarize and analyze the EMSs-disorder associations in studies in which patients with specific psychiatric diagnoses were compared to healthy controls. Of the 28 studies that met the inclusion criteria, 27 were included in a meta-analysis. Across diagnoses, all EMSs were elevated in the clinical groups. The largest effect sizes were observed for the social isolation, the negativity/pessimism, the defectiveness/shame, and social undesirability schemas. Depression (n = 8), borderline personality disorder (n = 5), and obsessive–compulsive disorder (n = 5) were the most frequently studied mental disorders. Heterogeneity between studies was high. Results suggest that mental disorders are not characterized by specific EMSs.

Effects of a Cognitive Schema Account on the Stigma of Schizophrenia: A Study in a French University Student Sample

Among people with psychiatric disorders, those with schizophrenia are subject to high levels of stigmatization. Research is necessary to identify new strategies that may help reduce the stigma of schizophrenia. Educational strategies using cognitive accounts, particularly early maladaptive schemas (EMSs), have shown promising results in the context of depression, but they have not been evaluated in the context of schizophrenia. The present study compared the effect on the stigma of three different educational strategies, based on cognitive distortions, biogenetics, and EMSs. A total of 378 students were randomly assigned to 1 of 4 groups. Three experimental groups were presented with a vignette that introduced 1 of 3 different etiological accounts of schizophrenia (cognitive distortions, EMSs, or biogenetics). The fourth group was presented with a text unrelated to schizophrenia. The participants completed questionnaires that measured their attitudes, empathic concern, and social distance toward people with schizophrenia, before and after reading the text. The intervention using the EMS etiology account for schizophrenia was the only one that led to a significant decrease in stigma. The latter effect was driven mainly by an increase in the level of empathic concern toward people with schizophrenia. Given that similar results have been observed for depression and that the role of EMSs in many psychiatric disorders has been demonstrated, studying the effects of EMS explanations for other stigmatized disorders may be promising for reducing the stigma of psychiatric disorders.

Suicidal ideation, suicide literacy and stigma, disclosure expectations and attitudes toward help-seeking among university students: The impact of schizotypal personality traits

BACKGROUND

Similarly to patients with schizophrenia, non-clinical individuals with schizotypal traits have been reported to show an increased risk for suicide-related outcomes. We aimed to assess suicidal ideation, and to determine factors that may have associations with help-seeking attitudes in high schizotypal individuals as compared to low schizotypal individuals.

METHOD

We carried out a cross-sectional survey. The Schizotypal Personality Questionnaire, the attitudes toward seeking professional psychological help scale-short form, the disclosure expectations scale, the scale of suicide ideation, the stigma of suicide scale-short form, the literacy of suicide scale, and the depression anxiety stress scales were administered to 504 college students. A total of 51 students were classified in the high-schizotypy group, and 50 were classified in the low-schizotypy group.

RESULTS

High-schizotypal students experienced significantly more suicidal ideation, had greater literacy of suicide, had more glorification of suicide, had higher anticipated risks of disclosure and more negative help-seeking attitudes than low-schizotypal students. After controlling for sociodemographic (age, gender, income and tobacco use) and psychosocial variables (personal psychiatric history, family history of suicide, personal history of suicide attempt[s]), depression and suicide ideation), disclosure expectations had both a significant negative independent effect through anticipated risks, and a positive independent effect through anticipated benefits, on high-schizotypal students' help-seeking attitudes.

CONCLUSION

The apprehension and reluctance to seek help found in high-schizotypal students highlight an urgent need to further understand barriers to help-seeking among at-risk adolescents, and what may motivate them to reach out for support when they are more at-risk for suicide.

Negative symptoms: associations with defeatist beliefs, self-efficacy, and maladaptive schemas in youth and young adults at-risk for psychosis

BACKGROUND

Investigations into possible mechanisms that may contribute to the development, maintenance, and exacerbation of negative symptoms are needed. Defeatist beliefs, self-efficacy, and early maladaptive schemas have been shown to contribute to negative symptoms in schizophrenia. Likewise, negative symptoms occur in those at clinical high-risk (CHR) for psychosis.

AIMS

The aim of this study was to determine if negative symptoms were associated with defeatist beliefs, self-efficacy, and early maladaptive schemas in CHR participants of a group therapy intervention study.

METHOD

All CHR participants (n = 203; 99 males, 104 females) were recruited as part of a three-site randomized control trial: Recovery through Group Study (ReGroup). Negative symptoms, defeatist beliefs, self-efficacy and early maladaptive schemas were assessed by trained clinical raters. Mediation analyses were conducted to examine the relationship between defeatist beliefs, self-efficacy, functioning, and negative symptoms.

RESULTS

The majority of CHR youth (72.9%) had at least one negative symptom of moderate to above moderate severity at baseline. In multiple mediation analyses, both asocial beliefs and social self-efficacy mediated the effects of social functioning on negative symptoms. Finally, defeatist performance attitudes significantly mediated the effects of role functioning on negative symptoms.

CONCLUSIONS

These results highlight the importance of considering beliefs and attitudes in relation to functioning and severity of negative symptoms. Psychosocial interventions may wish to target beliefs and attitudes in effort to reduce negative symptoms and improve functioning in CHR youth.

Childhood maltreatment, cognitive emotion regulation strategies, and alcohol craving and dependence in alcohol-dependent males: Direct and indirect pathways

OBJECTIVES

Childhood maltreatment (CM) and cognitive emotion regulation strategies (CERSs) may be important in alcohol craving and dependence in alcohol-dependent individuals. The aim of this study was to evaluate direct effects of CM on the subscales of alcohol craving and alcohol dependence and its indirect effects via CERSs in individuals with a diagnosis of alcohol dependence.

METHODS

In a cross-sectional design, 329 alcohol-dependent males completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Cognitive Emotion Regulation Questionnaire-Short version (CERQ-Short), the Alcohol Dependence Scale (ADS), the Obsessive Compulsive Drinking Scale (OCDS), and the Beck Depression Inventory-II (BDI-II).

RESULTS

Participants with alcohol dependence had early age of onset of alcohol use (mean = 20.78 years), relatively long duration of alcohol use (mean = 11.14 years), and low education (mean = 9.55 years). Indirect effects were observed from CM to the subscales of alcohol craving and dependence only through maladaptive CERSs after adjusting for demographic and clinical factors. No direct effect was observed through CM on the subscales of alcohol craving and dependence.

CONCLUSIONS

Although drawing causal conclusions from the current research is impossible, the findings suggest that maladaptive CERSs may be a possible mechanism relating CM to alcohol craving and dependence in treatment-seeking alcohol-dependent individuals, while adaptive CERSs may be less important regarding this relation. However, the findings of the current study need longitudinal research.

Effects of childhood emotional maltreatment on depressive symptoms through emotion dysregulation in treatment-seeking patients with heroin-dependence

BACKGROUND

Although individuals who experience childhood emotional maltreatment (CEM) are more likely to use maladaptive emotion regulation strategies, resulting in vulnerability to depression, no research has examined whether emotion dysregulation may explain the association between CEM and current depressive symptoms in a clinical sample of heroin-dependent individuals.

OBJECTIVES

The current study aimed to assess the direct effect of CEM on current depressive symptoms and its indirect effect via emotion dysregulation in a treatment-seeking sample of males with heroin dependence. In a cross-sectional design, participants (N = 350) completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Difficulties in Emotion Regulation Scale (DERS), the Obsessive-Compulsive Drug Use Scale (OCDUS), and the Beck Depression Inventory-II (BDI-II).

RESULTS

Emotional abuse and neglect severity had significant direct effects on current depressive symptoms and significant indirect effects through emotion dysregulation after controlling for clinical factors related to heroin use.

LIMITATIONS

Study limitations include the cross-sectional design and use of self-report scales.

CONCLUSIONS

Findings suggest emotion dysregulation may increase depressive symptoms in heroin users who experienced CEM. Training in emotion regulation strategies may decrease depressive symptoms in heroin-dependent individuals with CEM. Additional research with a longitudinal design to confirm these results is warranted.

Childhood trauma and the likelihood of increased suicidal risk in schizophrenia

The aims of the present study were to investigate the dimensions of childhood trauma (CT) in patients with schizophrenia, and to predict suicidal risk (e.g., current suicidal ideation and lifetime suicide attempts) by CT dimensions and clinical factors (positive and negative symptoms and depression). Eighty-two inpatients with schizophrenia completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory-II (BDI-II), and the Beck Scale for Suicide Ideation (BSSI); they were also administered the Positive and Negative Syndrome Scale (PANSS).The presence of lifetime suicide attempts was assessed by structured diagnostic clinical interview. Patients with lifetime suicide attempts scored higher on sexual abuse than those without attempts after controlling for depression severity. Patients with high suicidal risk had higher scores on physical neglect than those without high risk after controlling for depression severity. Patients with high CT had higher scores on negative and positive symptoms, current suicidal ideation, and depression than those with low CT. Logistic regression analyses indicated that sexual abuse was a unique predictor of lifetime suicide attempts, and that physical neglect and depression were unique predictors of current suicidal ideation. These findings indicate that patients with schizophrenia who have experienced CT may be at increased risk for suicide.

Early maladaptive schemas and suicidal risk in inpatients with bipolar disorder

The present study aimed to assess the associations of early maladaptive schemas (EMSs) and clinical factors (hypomanic/manic and depressive symptoms) with suicidal risk (current suicidal ideation and lifetime suicide attempts) in inpatients with bipolar disorder (BD). One hundred inpatients with BD completed the Young Schema Questionnaire-Short Form (YSQ-SF), the Bipolar Depression Rating Scale (BDRS), the Young Mania Rating Scale (YMRS), and the Beck Scale for Suicide Ideation (BSSI). 59% of patients had lifetime suicide attempts and 59% showed high suicidal risk (BSSI ≥ 6). BD patients with lifetime suicide attempts had higher scores on the entitlement and social isolation schemas, depression, and hypomanic/manic symptoms than those without such attempts. Patients with high suicidal risk had higher levels of depressive and hypomanic/manic symptoms as well as some EMSs than those without high suicidal risk. Logistic regression analyses revealed that hypomanic/manic symptoms as well as the entitlement and defectiveness schemas were significantly associated with current suicidal ideation. Also, the entitlement and social isolation schemas were associated with lifetime suicide attempts. These results suggest that the entitlement, social isolation, and defectiveness schemas may relate to suicidal risk in patients with BD.
