Do people diagnosed with psychosis spectrum disorders share the same personality space as the general population? Big Five complemented by the proneness to psychotic-like experiences/behaviors

OBJECTIVE

Disintegration is a recently proposed broad, trait-like reconceptualization of the proneness to psychotic-like experiences/behaviors.

METHODS

We tested the assumption that the 6-factor model (Five-Factor traits plus Disintegration) was the most adequate one and that it was invariant across clinical and non-clinical populations. The clinical sample (n = 161) consisted of patients who had at least one psychotic episode, duration of illness less than 10 years, currently in remission. The general population (n = 409) was matched with the patient sample by age, gender, and education. NEO PI-R and DELTA were used to measure personality dimensions in both samples. Invariance of one to six-factor solutions was tested by Exploratory Structural Equation Modeling.

RESULTS

We found that: (a) several criteria for deciding on the number of factors to retain converged to the conclusion that the assumed 6-factor model was the most adequate one, (b) the assumed factorial structure appeared to satisfy the criteria for the scalar invariance across the two samples, (c) all nine Disintegration subdimensions separated from the Big Five, forming the Disintegration factor, and (d) Disintegration was unrelated to Openness.

CONCLUSION

The Big Five personality structure-complemented with disintegration-was invariant across individuals from the general population and patients with psychosis.

Preliminary Assessment of Pre-Electroconvulsive Therapy Evaluation Practices in European Countries: The Need for Guidelines

OBJECTIVES

Pre-electroconvulsive therapy (ECT) evaluation is an essential part of ECT preparation, a standard treatment in the psychiatric field. However, no routine pre-ECT evaluation has been published so far. This preliminary study aimed to explore different practices in pre-ECT evaluation across European countries.

METHODS

The data were collected as a snowball sample approach using an online survey from September 2019 to April 2020. The final analysis included data from 18 clinics placed in 16 European countries.

RESULTS

Regulations on the pre-ECT evaluation were found in 9 countries. All clinics reported doing complete blood count, serum electrolytes, and renal function analysis as a part of regular laboratory testing, alongside with a cardiovascular assessment. Ten clinics reported using psychiatric scales. Six clinics reported doing a cognitive assessment, of which all had regulations on the pre-ECT evaluation. Not one evaluation had the same sets of procedures and diagnostics.

CONCLUSIONS

The differences in assessment approaches mirror high variability of the pre-ECT evaluation practice across Europe. Cognitive assessment and objectification of psychiatric symptoms should be a regular part of the pre-ECT evaluation because of the monitoring of the most common adverse effect and observing the clinical response to ECT. Standardization of the pre-ECT evaluation and ECT in general would remove criticisms and opposition to the treatment, make it based on the best of our knowledge, and provide a method respectful of patients' best interests and rights.

Implementing a digital mental health intervention for individuals with psychosis - a multi-country qualitative study

BACKGROUND

Implementation of psychosocial interventions in mental health services has the potential to improve the treatment of psychosis spectrum disorders (PSD) in low- and middle-income countries (LMICs) where care is predominantly focused on pharmacotherapy. The first step is to understand the views of key stakeholders. We conducted a multi-language qualitative study to explore the contextual barriers and facilitators to implementation of a cost-effective, digital psychosocial intervention, called DIALOG+, for treating PSD. DIALOG+ builds on existing clinician-patient relationships without requiring development of new services, making it well-fitting for healthcare systems with scarce resources.

METHODS

Thirty-two focus groups were conducted with 174 participants (patients, clinicians, policymakers and carers), who were familiarized with DIALOG+ through a presentation. The Southeast European LMICs included in this research were: Bosnia and Herzegovina, Kosovo, (Kosovo is referred throughout the text by United Nations resolution) North Macedonia, Montenegro and Serbia. Framework analysis was used to analyse the participants' accounts.

RESULTS

Six major themes were identified. Three themes (Intervention characteristics; Carers' involvement; Patient and organisational benefits) were interpreted as perceived implementation facilitators. The theme Attitudes and perceived preparedness of potential adopters comprised of subthemes that were interpreted as both perceived implementation facilitators and barriers. Two other themes (Frequency of intervention delivery; Suggested changes to the intervention) were more broadly related to the intervention's implementation. Participants were exceedingly supportive of the implementation of a digital psychosocial intervention such as DIALOG+. Attractive intervention characteristics, efficient use of scarce resources for its implementation and potential to improve mental health services were seen as the main implementation facilitators. The major implementation barrier identified was psychiatrists' time constrains.

CONCLUSIONS

This study provided important insights regarding implementation of digital psychosocial interventions for people with PSD in low-resource settings by including perspectives from four stakeholder groups in five LMICs in Southeast Europe - a population and region rarely explored in the literature. The perceived limited availability of psychiatrists could be potentially resolved by increased inclusion of other mental health professionals in service delivery for PSD. These findings will be used to inform the implementation strategy of DIALOG+ across the participating countries. The study also offers insights into multi-country qualitative research.

Gender differences in depression, anxiety, and stress during the first wave of the COVID-19 pandemic in serbia - results from an online survey

Introduction

COVID-19 outbreak has significantly affected the mental health of people worldwide. The first wave of the pandemic began during the beginning of March 2020, and included significant preventative measures. Previous research on mental health differences between the genders has found that women were more likely to exhibit symptoms of anxiety during the COVID-19 outbreak.

Objectives

The aim of our study was to assess the differences between the genders in depression, anxiety, and stress.

Methods

An online survey designed for the purposes of this study was distributed using the snowballing method during April and May of 2020. The survey consisted of two parts: sociodemographic and clinical data, and COVID-19 related data. Participants also filled out the Depression, Anxiety and Stress Scale (DASS-21) - a well validated, self-questionnaire instrument. T-test for independent samples was used to evaluate the differences between the genders.

Results

Out of the initially sent 563 surveys, a total of 161 were included in further analyses (28.6% response rate). Mean age of the sample was 42.2±10.2 and 65.2% of the participants were female. Mean scores on DASS-21 were as follows: 8.78±6.66 on depression, 9.78±7.39 on anxiety and 7.76±7.14 on stress. Females scored significantly higher on depression (t=-2.25, p=0.029), anxiety (t=-2.25, p=0.028), stress (t=-2.44, p=0.017), and total DASS-21 score (t=-2.44, p=0.016).

Conclusions

The results of our study imply that female participants exhibit higher levels of depression, anxiety, and stress during the COVID-19 pandemic. Larger, population-based studies could provide a mroe in-depth answer to the importance of these differences for the general population.

Long-Term Benzodiazepine Prescription During Maintenance Therapy of Individuals With Psychosis Spectrum Disorders-Associations With Cognition and Global Functioning

BACKGROUND

Cognitive difficulties have a significant impact on life functioning and overall well-being in patients with psychosis spectrum disorders (PSDs). There are indications that continuous use of benzodiazepines (BZDs) in various patient groups has a detrimental effect on cognition. Our aim was to explore the association between long-term BZD prescription, global functioning, and cognitive functioning in persons with PSD.

METHODS

This exploratory study included 55 PSD patients, recruited from 2 outpatient services in Serbia. Patients were grouped into BZD long-term prescription group and BZD-other group. Brief Psychiatric Rating Scale was used for symptom assessment, functioning was measured by Global Assessment and Functioning Scale, and cognition was assessed by the Global Assessment of Functioning-Cognition in Schizophrenia Scale.

RESULTS

The sample comprised 52.7% patients who were prescribed with BZD for 6 months or more continually (29/55), with a mean daily dose of 3.16 ± 0.66 mg lorazepam equivalents. There were no differences between study groups in any of the sociodemographic characteristics, duration of illness, or antipsychotic daily dosages. The BZD long-term prescription group had lower global (P < 0.01) and cognitive functioning (P < 0.01), higher Brief Psychiatric Rating Scale scores (1.86 vs 1.58, respectively, P < 0.01), and more psychotropic drugs prescribed on a daily basis than the other group (median: 4 vs 2, respectively, P < 0.01).

CONCLUSIONS

The study explored a topic that continues to be underresearched, especially in the Balkans. Prospective studies and comprehensive cognitive batteries are needed to further elucidate the associations between polypharmacy, long-term BZD use, cognitive functioning, and global functioning during maintenance therapy of individuals with PSD.

Factorial Structure of the Serbian Version of the Clinical Assessment Interview for Negative Symptoms - Evidence for Three Factors of Negative Symptoms

Introduction: Negative symptoms are a common occurrence in patients with psychosis spectrum disorders. Previous analysis of the latent structure of the Clinical Assessment Interview for Negative Symptoms (CAINS) - which was developed to advance the assessment of negative symptomatology - showed two underlying sub-domains (Motivation and Pleasure; Expression). Recent findings indicate that a more complex structure might be more applicable. Aim: To evaluate the psychometric properties of the Serbian version of the CAINS in a sample of outpatients (N = 67) with psychosis spectrum disorders. Materials and Methods: Negative symptoms and general level of psychopathology were assessed with Serbian translations of the CAINS, the 53-item version of the Brief Symptom Inventory (BSI), and the 24-item version of the Brief Psychiatric Rating Scale (BPRS). Principal component analysis (PCA) was carried out on the CAINS items, and correlation analyses were done to assess its convergent and discriminant validity. Results: Our results showed an excellent internal consistency (Cronbach's alpha = 0.92). PCA revealed a three-component solution consisting of Expressiveness and Motivation for Social and Family Relationships (Factor 1), Motivation for Vocational Activities (Factor 2), and Motivation for Recreation (Factor 3). Convergent validity was supported by significant correlations with the Negative symptoms domain of the BPRS (Factor 1, 0.695, p < 0.01; Factor 2, 0.352, p < 0.05; Factor 3, 0.452, p < 0.01). When assessing discriminant validity, weak correlations were found with BPRS and BSI scores. Conclusion: The Serbian version of CAINS is a valid, reliable and useful tool for the assessment of negative symptomatology. Our findings support a three-factor structure of CAINS, which indicates that the construct is more complex than envisaged by the original conceptualization of two distinct factors.

Maintenance phase treatment of psychotic disorders in outpatients from Serbia - focus on long-term benzodiazepine use

Introduction: Prescribing trends in maintenance therapy of patients with primary psychotic disorders (PSD) may vary worldwide. Present study aimed to investigate prescription patterns in a sample of outpatients with PSD from Serbia.Methods: In a sample of 73 PSD outpatients we analysed the rate of antipsychotic polypharmacy and psychotropic polypharmacy, concomitant continual benzodiazepine use, and associations between therapy, psychotic symptoms and quality of life.Results: Maintenance therapy (median daily dose 321 mg of chlorpromazine equivalents) predominantly consisted of monotherapy with second generation antipsychotics (45.2%), followed by antipsychotic polypharmacy based on first and second generation combination (25.0%). The median number of psychotropic drugs was 3. Benzodiazepines were continually prescribed to more than 60% of patients (mean daily dose 2.9 ± 2.0 mg lorazepam equivalents). Patients with benzodiazepine use had significantly more psychotropic medications and more antipsychotic polypharmacy, poorer quality of life and more severe psychopathology in comparison to another group.Conclusion: The present study demonstrated new information regarding the prescription patterns of psychotropic drugs in outpatients with PSD in Serbia, amplified with clinically relevant information. This study also revealed distinct prescription patterns concerning antipsychotic/benzodiazepine polypharmacy. Overall, such findings are likely to contribute to improving clinical practice and care for patients with PSD in general.KeypointsPresent exploratory research aimed to elucidate trends of antipsychotics polypharmacy and concomitant use of psychotropic medications including benzodiazepines in the maintenance treatment of outpatients with schizophrenia and other psychotic disorders, amplified with clinically relevant information (symptoms and quality of life).'Antipsychotic (AP) polypharmacy' was defined as concurrent use of more than one AP for at least 1 month; 'Psychotropic polypharmacy' was defined as the combination of AP and a different class of psychotropic drugs medication for at least one month.The median number of prescribed psychotropic drugs was 3 (mean 3.1 ± 1.1) and the average AP daily dose was moderate (median 321 mg of chlorpromazine equivalents). However, the rates of AP polypharmacy (45.2%) and benzodiazepine prescription on a continual basis (>60%) found in our sample could be considered relatively high.Outpatients with higher AP daily dose and higher BPRS symptom score were receiving more benzodiazepines.For improvement of the local, as well as general clinical practice and care for patients with psychotic disorders, and for education in psychiatry, such analyses need to be done on a regular basis and on larger samples.
