16-year-old female who starts psychiatric follow-up due to episodes of anxiety crises with dizziness and tremors.

To expose a case in which it is essential to rule out organic pathology in cases where there is anxiety and physical symptoms.

Case report and literature review

The patient explains that she was in a situation of conflict with her ex-partner, commenting that he did not accept the breakup. Sertraline was prescribed in ascending doses up to 100 mg per day with complete remission of anxiety. 8 months later, she went to the emergency room for loss of consciousness and tremor of the lower limbs. She was diagnosed with conversive disorder and was prescribed lorazepam up to 3 mg per day. Since then, there has been a worsening in the frequency of syncope occurring up to 10 times a day, limiting her academic and social life. She was evaluated by a cardiologist who diagnosed Pots Syndrome (postural orthostatic tachycardia syndrome) and started treatment with ivabradine and mineralocorticoids. With this treatment, the episodes were drastically reduced and spaced out to 1-2 per week. The dose of lorazepam is decreased until its withdrawal without worsening of the anxious symptomatology.

This disorder consists of an involvement of the autonomic nervous system in which there is a sudden drop in blood pressure together with an abrupt increase in heart rate. Its treatment is based on increasing blood volume with drugs such as corticosteroids as well as postural measures with adequate water intake.

Schizophrenia is characterized by impairments in motivation and coping and decrements in psychosocial functioning in major life areas.

This study attempted to examine the links between treatment motivation, coping, and psychosocial functioning for persons with schizophrenia. Design: Cross-sectional survey.

One hundred thirty-eight participants were recruited at random from outpatient psychosocial rehabilitation programs in Moscow-based psychiatric hospitals. The measures of motivation were administered by testers blind to scores on other study variables; measures of coping (COPE, CERQ) and psychosocial functioning (PSP, EQ5D5L, SF36, Q-Les-Q-18) were administered. Data were analyzed using latent construct modeling to test for mediator and moderator effects.

There were strong bivariate relationships between coping, motivation, and psychosocial functioning. The results demonstrated that coping strongly mediated the relationship between motivation and psychosocial functioning. This mediation was evidenced by: 1) the direct path from motivation to a functional outcome no longer being statistically significant after introducing coping into the model; 2) the statistical significance of the indirect path from motivation through coping to functional outcome. There was no support for the moderation hypotheses.

Motivation influences psychosocial functioning through its relationship with coping, and coping is a critical mechanism for explaining the relationship between motivation and psychosocial functioning. These results will be compared with work on motivation, neurocognition, and psychosocial functioning in schizophrenia (Nakagami et al. 2008), as well as with gender issues. Professionals working with schizophrenia patients should consider such variables as coping when designing and implementing gender-sensitive intervention programs.

Despite the large amount of research concerning the impact of COVID-19 on health care workers, to date few targeted MHWs. Moreover, none has investigated the vulnerability due to exposure to previous traumatic events among health care workers.

This study aimed to investigate the psychological distress in MHWs after the first lockdown imposed by the COVID-19 pandemic in the more impacted regions of the North of Italy, to understand which COVID-19, sociodemographic and professional variables as well as previous stressful life experiences, could have had greater negative effects.

The online survey occurred from 28-June to 10-August 2020. This included questions regarding sociodemographic factors, professional information, COVID-19 exposure. Moreover, three validated self-report questionnaires were administered: Life Events Checklist for DSM-5 (LEC-5), Impact of Event Scale-Revised (IES-R), Depression Anxiety Stress Scales-21 (DASS-21).

271 MHWs completed the survey. At least 20% had elevated levels of psychological distress with post-traumatic symptoms. Stratifying for professional roles, the nurses resulted the most affected, with significantly higher scores in terms of intrusive thoughts, hyperarousal and avoidance behaviors. Several variables affected psychological distress in MHWs, but stronger effects were done by age, professional roles, increased workload and worst working environment during COVID-19 pandemic, to had experienced the separation of family members, but also had experienced during their life of a severe human suffering (physical and/or psychological) on oneself or on a loved one.

Our data underlying the importance of recent but also previous severe stressful events as risk factors to develop post-traumatic symptoms reducing the resilience of the subjects investigated.

The COVID-19 pandemic, and the consequent recession, have caused a decline in the job market, with the resultant job insecurity increasing the risk of depression. While this affected all genders, suicidal thoughts were observed to be more common among women than men, suggesting that the impact of unemployment on depression varies by gender, with gender differences affecting the outcome of depression.

This study aims to verify the moderating effect of gender on the structural relationship between unemployment, depression, and suicide during the COVID-19 pandemic by using online search trend data.

The study utilized the search trend data from Naver’s Data Lab service, by analyzing the searches of men and women under 65, between March, 2020 and September 12, 2021. The search terms were “unemployment,” “depression,” and “suicide.” The analysis examined 1121 searches using the Model 7 research model through the SPSS Process Macro to verify the moderating effect of gender on the mediating pathways for unemployment, depression, and suicide.

We observed that searches for “unemployment” significantly increased with searches for “depression” (B=1.860, p<.001) and “suicide” (B=.860, p<.001). The analysis further revealed that the correlation between the increase in searches relating to depression and unemployment was seen more in women than men. This resulted in an accompanying increase in the volume of searches for suicide (B=2.341, p<.001).

The job insecurity caused by the COVID-19 pandemic led to varying degrees of depression according to gender. Thus, social security measures related to unemployment, depression, and suicide interventions require a gender-specific approach.

Cultural psychiatry is an area of psychiatry that has been growing in importance recently. According to the new definition, mental health requires harmony with the universal values of society (Galderisi et al., 2017). Faith is considered an important factor in culture. Theology can enable a better understanding of psychiatric problems and distinction between spiritual and mental issues. “Pastoral theology aims at constructing models of redeeming activity of the Church which are current in these days, and will be current in the nearest future” (Przygoda, 2013). This discipline must recognize and evaluate the impact of contemporary sciences, including psychiatry, on theology and ecclesiastical activity.

This study aims to prepare a modern concept of pastoral psychiatry, which will be used to prepare a textbook, teaching aids and teaching plan for this discipline.

Textbooks and articles in psychiatry, psychology and related disciplines, and pastoral theology monographs were analyzed. This was followed by the conceptualization of areas of interest and methodological standards.

Textbooks on this problem were published several decades ago (Gabriel, 1933; Bless, 1949; Polish edition issued in 1980, translated with amendments by Kaczmarek). Since then, knowledge has advanced considerably. Textbooks of psychiatry and psychology only selectively consider the Christian perspective.

“Pastoral Psychiatry” should be helpful for priests, theologians, believers, doctors, psychologists. It requires the work of authors with theological and psychiatric competence. It will create ways of agreement, facilitate understanding of different perspectives, increase competence: theologians, priests – to better understand modern psychiatry; psychiatrists, psychologists – to better help religious patients.

Anorexia nervosa is an eating behavior disorder that is often related to various personality factors. The relationship between obsessive compulsive disorder and eating Disorders has been highlighted.

To present a clinical case of a patient with eating disorder and gastric bezoar, secondary to compulsive hair ingestion.

Bibliographic review of articles published in relation to the comorbidity of these disorders, based on articles published in the last 5 years in Pubmed.

26-year-old female. Diagnosis of restrictive anorexia nervosa. She was admitted to the hospital on two occasions for nutritional disorders. In the last admission, she reported greater anxiety and significant weight loss. She reports that she has limited her food intake, but she does feel thin and is unable to eat for fear of gaining weight. Ruminative thoughts about her body image. During admission, the patient expressed a sensation of fullness, nausea and vomiting, later observing in abdominal X-ray and gastroscopy, the presence of a gastric trichobezoar, which was finally resolved conservatively.

Trichotillomania is observerd in 1 in 2000 people, trichophagia is even less frequent. According to DSM- V, these disorders are grouped within obsessive-compulsive spectrum disorders. A Trichobezoar is a conglomerate that can be found in the stomach or intestine, composed mainly of hair, previously ingested. Trichotillomania can be associated with anorexia nervosa, especially in patients with obsessive personality traits, which occurs frequently. The gastric slowing that patients with anorexia often present is a factor that favors the formation of the bezoar

Generic psychometric instruments are frequently used in psychiatric practice. When a respondent provides an affirmative reply to two contrasting items in such a questionnaire (e.g. “I am reserved” and “I am outgoing”), serious questions need to be asked about the respondent, the instrument, and the interaction between the two.

The research aims to identify reasons which could explain the contradictory answers provided by respondents to a well-established, and seemingly psychometrically sound instrument.

World Values Survey data, collected in South Africa (N = 3 531), were analysed, focusing on the personality survey, where contrasting response to matching items were identified. Exploratory factor analyses were used to inspect the factorial structure of the instrument across groups, after which measurement invariance tests were done.

The theorised factorial structure of the personality survey did not mirror the structure in the South African sample. This was demonstrated in the inspection-report, as well as in the tests of measurement invariance. However, in some groups, specifically those who were well-versed in English and possessed higher levels of education, the structures were replaceable.

The assumption that well-established instruments are valid in settings different to the one where they were initially developed, should be questioned, and such instruments should not be used unless thoroughly tested. This presentation exposes the extent of measurement non-invariance when using an instrument in a foreign setting and shows how this can be detected and addressed. Those working with foreign individuals or conducting cross-cultural research should be particularly aware of these threats to validity.

Approximately one-third of stroke survivors develop poststroke depression. Post-stroke mania is relatively rare, with a prevalence of less than 2%. One review of case reports of late-onset mania in 2015 demonstrated that 51% of the patients had established vascular risk factors. In 28% of cases, the treatment of underlying organic cause contributed to successful remission of the manic episode.

For this review, we aimed to compile published case reports from the past 20 years to review late-onset mania as one of the neuropsychiatric outcomes of stroke and its management.

literature search on Pubmed, PsychInfo, and Embase utilizing keywords combinations: Bipolar, Manic, Mania, Secondary, Stroke, Poststroke, Post-stroke, Elderly, Old, Late onset, Late-onset, Lateonset, Hemisphere, Brain, Vascular, Infarction.

Among the 17 case reports, the age of onset of manic episode ranged from 47 to 86 with a mean of 67 years. Of the 17 cases, the right hemisphere was the most frequently affected (14/17, 82%), with cerebrovascular lesion involving the left hemisphere in 3 cases (17.6%).

Clinicians should consider mania secondary to an organic cause in patients presenting with focal or soft neurological signs or symptoms, manic episode with atypical symptoms such as visual or olfactory hallucinations, altered mental status, disorientation, impairment in memory or cognition, unusual age of onset for bipolar disorder, or unusual illness course such as single episode of mania or poor response to psychopharmacologic treatment. Some reviews suggest combination of mood stabilizers and second-generation antipsychotics. Benzodiazepines recommended as an adjunctive drug for acute management such as agitation, aggressive behavior or disinhibition.

Bipolar Disorder(BD) is a common,severe and recurrent disease with significant effects on functionality. Residual symptoms such as sleep disturbance and sexual dysfunction are defined as predictors of poor functioning in remission.

The aim of this study was to investigate the correlation between sleep disorder and severity of sexual dysfunction in patients with BD in remission.

The study was conducted with 100 female and 100 male BD patients in remission. The sociodemographic and clinical characteristics were recorded by interview with the patients and the patients were given the Young Mania Rating Scale(YMRS),Hamilton Depression Rating Scale(HAM-D),Pittsburg Sleep Quality Index(PSQI),Epworth Sleepiness Scale(ESS),Female Sexual Function Scale(FSFI) and International Index of Erectile Function(IIFF-15)for the assesment of symptom severity.

The frequency of “sleep disorder” was 45.5% and the frequency of ’’daytime sleepiness’’ was 5.5%.In women the mean FSFI score was 26.06±5.14 and sexual dysfunction frequency was 48%.In men,the mean IIEF score was 59.63±8.34 and erectile dysfunction frequency was 56%. There was a statistically significant negative correlation between total FSFI score with HAM-D(r=-0.592, p <0.001),ESS (r=-0.330, p=0.001)and PSQI(r=-0.557, p<0.001)and between total IIEF score with HAM-D(r=-0.509, p<0.001),ESS(r=-0.361, p<0.001)and PSQI(r=-0.511,p<0.001). Sexual function scores in both women and men with sleep problems were significantly lower than those without sleep problems(23.56±4.71vs.28.56±4.31and53.88±7.10vs.63.80±6.56 respectively). Multiple linear regression analysis also showed that total sleep quality scores were an effective factor on sexual function in women(OR:2.74,%95CI[0,799-0,127];p=0,007) and men(OR:2.45, %95CI[1.577-0.164];p=0,016) with BD.

There was an increased incidence of sexual dysfunction in bipolar patients with sleep disorders.Treatment of sleep disorders is important for improving sexual function in bipolar patients for both genders.

Since the COVID-19 pandemic start in early 2020, there have been reports of a high prevalence of neuropsychiatric symptoms. Cognitive impairment is being increasingly recognized as an acute and possibly long-term sequel of the disease. According to recent data, limited evidence point to SARS-CoV-2 having a preferential neurotropism for the frontal lobes, as suggested by behavioral and dysexecutive symptoms, frontotemporal hypoperfusion on MRI, EEG slowing in frontal regions, and frontal hypometabolism on 18F-FDG-PET. Nevertheless, there isn’t a specific biomarker.

Brief literature review about the relationship between COVID-19, cognitive impairement onset and risk for dementia.

Non-systematic review through PubMed research using the terms “COVID-19”, “SARS-CoV-2”, “pandemics”, “cognitive impairement”, “dementia” and “risk factor”.

Direct neuronal infection via angiotensin-converting enzyme 2 receptor (ACE2R), hyperinflammation, brain ischemia related to respiratory failure or thromboembolic strokes, and severe psychological stress are the mechanisms more associated with a deleterious effect on cognition. The relation between SARS-CoV-2 infection and neurodegenerative diseases is still unclear. However, the high expression of the ACE2R in the brain, may explain the acute brain damage and could also be the basis for later neurodegenerative changes. The potentially long-term nature of the deficits makes it important to do an early identification, management, rehabilitation and follow-up of the patients exhibiting cognitive symptoms.

Given the reports of brain damage by SARS-CoV-2, there are concerns that this damage may substantially increase the incidence of neurodegenerative diseases and promote dementia. Further long-term studies may be required to identify the relationships between SARS-CoV-2 infection and risk for dementia.

Attention Deficit / Hyperactivity Disorder (ADHD) is a highly prevalent neurodevelopmental condition characterized by inattention, motor hyperactivity and impulsivity. ADHD cognitive and behavioral presentation is characterized by a high heterogeneity (APA, 2013). Indeed, a complex diagnostic process, that considers several validated tools, is, to date, necessary.

The main aim is to develop supervised machine learning (ML) algorithms that could be used to support the diagnostic process for ADHD, by identifying the most relevant features in discriminating between the presence or absence of the ADHD diagnosis in children.

We analyzed data from 342 children (Mean age: 8y 8m ± 1y; 61 F) referred for possible ADHD symptomatology. Assessments were performed by an expert clinician and through questionnaires: Social Responsiveness Scale (SRS), Child Behavior Checklist (CBCL), Conners Rating Scale for Parents (CPRS) and for Teachers (CTRS). Data were analyzed using a decision tree classifier and random forest algorithms.

The decision tree model performed an accuracy of 0.71. The random forest model that was identified as the best tested, performed an accuracy of 0.77 (Figure 1) and it identified as most informative parent- and teacher-rated DSM-oriented ADHD symptoms (Figure 2).

Figure 2: Ranking of variables importance.

A random forest classifier could represent an effective algorithm to support the identification of ADHD children and to simplify the diagnostic process as an initial step. The use of supervised machine learning algorithms could be useful in helping the diagnostic process, highlighting the importance of a personalized medicine approach.

International experience convincingly shows the prevalence of mental disorders secondary to COVID-19, the pathogenesis of which includes biological and psychosocial factors, which characterizes this area of research as relevant and timely.

Analysis of the structure of the most common forms of psychopathology within consequences in COVID-19.

The study involved 45 patients with depressive episodes of varying severity (F 32.0, 32.1, 32.2) and 37 ones with anxiety disorders (F 40, 41). The average age of the examined groups was 39.42 ± 5.68 and 31.54 ± 4.36 years respectively. Clinico-psychopathological, psychodiagnostic, statistical methods were used.

Significantly more patients with depressive disorders before the first clinical manifestations of the disease experienced COVID-19 in mild and moderate form (31.82% and 68.18% of individuals, respectively) (p <0.05), while patients with anxiety disorders were more affected to some stressors of the SARS-COV-2 pandemic (including threatening information background (83.78% of people), quarantine measures in the form of self-isolation (75.66% of people), uncertainty of the impact of coronavirus infection on the socio-economic situation) (62.16% of people)) (p < 0.05). It was found that the examined patients with a history of coronavirus COVID-19 are more likely to have depressive and asthenic syndromes in the clinical picture (p < 0.05), while patients with psychogenic effects of the pandemic - anxiety-phobic and somato-autonomic syndromes (p < 0,05).

Data on the influence of coronavirus disease COVID-19 and stressors of the SARS-CoV-2 pandemic on the formation of mental disorders of various genesis will allow to develop prevention algorithms and personalize therapeutic programs.

The COVID-19 pandemic has completely changed the experience of higher education with potentially negative consequences for students’ wellbeing.

To compare medicine/dentistry students’ depression/anxiety/stress levels before versus during the pandemic and to analyse the role of COVID-19-related stressors in their psychological distress.

Students from the Faculty of Medicine University of Coimbra answered socio-demographic and personality questionnaires and the Depression, Anxiety and Stress Scale/DASS before (academic years 2016-2017-2018-2019 - SAMPLE1; n=1000) and during (September-December 2020 and January-March 2021 - SAMPLE2; n=650) the COVID-19 pandemic. Mean age (21.12±3.75), personality traits scores, and gender proportions (»75% girls) did not significantly differ between samples. SAMPLE2 also filled in the Fear of COVID-19 Scale and a new version of the Inventory of Sources of Stress During Medical Education/ISSDME, containing a COVID-19 -related dimension (restrictions on training and on socializing with friends/colleagues).

SAMPLE2 presented significantly higher mean scores of depression (3.89±3.55vs.3.33±3.34), anxiety (3.27±4.08vs.2.86±3.29), stress (7.07±5.72vs.6.18±4.59) and total DASS (12.28±10.55vs.13.65±11.13) than SAMPLE1 (all p<.05). Fear of COVID-19 was a significant predictor of DASS score (adjusted R2=2.9%, p<.001). COVID-19-related stressors continued explaining significant increments of DASS variance after controlling for each of the ISSDME dimensions: Course demands (R2 Change=1.8%), Human demands (2.5%), Lifestyle (2.3%), Academic competition (5.5%), and Academic adjustment (5.2%) (all p<.001).

This study adds to the evidence of the negative impact of COVID-19 on students and emphasizes its pernicious role on medical students’ psychological distress, which is already higher due to the individual and academic stressors to which they are more exposed.

There is growing evidence that sexual minority men (e.g., gay, bisexual) experience lower sleep quality when compared to their heterosexual peers. Minority stress (e.g., discrimination, victimization) may account for these differences, however little is known about these relationships and how generalized anxiety may play a role in sleep disturbance.

Therefore, the aims of this study are to (a) understand the relationship between minority stress and sleep disturbance in a sample of sexual minority men, and (b) test whether these relationships are mediated by generalized anxiety.

In 2020, 241 sexual minority men were recruited across a south-eastern state in the USA. Participants were asked to respond to scales assessing perceived social stress, minority stress constructs (i.e., internalized homophobia, experiences of harassment, microaggressions), generalized anxiety, and sleep disturbance. Linear regressions were used to test the relationship between minority stress and sleep disturbance controlling for perceived social stress and to test mediation by generalized anxiety.

Two minority stress constructs (experiences of harassment, and microaggressions) and perceived social stress were found to have a positive relationship with sleep disturbance. Generalized anxiety symptoms fully mediated the relationship between minority stress and sleep disturbance.

Because sleep quality has a profound impact on health, findings from this study suggest the need for psychological intervention to improve sleep for sexual minority men. Given that generalized anxiety fully mediates the relationship between minority stress and sleep, targeted anxiety-based interventions have the potential to reduce sleep disturbance disparities between heterosexual and sexual minority men.

Pregnancy and the postpartum are generally characterized by positive feelings and expectations but they may also disguise maternal stress and difficulties. These are typical periods for the onset or relapse of psychiatric symptoms and disorders. Even though suicide during pregnancy and postpartum is rare, it is among the leading causes of maternal perinatal mortality.

To provide an overview on the risk of suicide during pregnancy and postpartum.

PubMed database was searched using combinations of the terms “suicide”, combined with “pregnancy” and “depression”.

The major risk factors for suicidal ideation are previous suicide attempts, self-harm, current or past history of psychiatric disorder, young maternal age, being unmarried, an unplanned pregnancy, substance use disorders, lack effective psychosocial support and discontinuation of psychotropic drugs. Pregnant women with suicidality behavior have also an increased risk for various adverse obstetric outcomes, including miscarriage, preterm delivery, maternal hemorrhage, and stillbirth. Furthermore, the postpartum period is often associated with the onset of mood and psychotic disorders with an increased risk of both suicide and infanticide. Women who have suffered from serious psychiatric conditions either after childbirth or in other phases of life should be informed about the possibility of relapse after subsequent pregnancies, thus presenting a higher risk of suicide.

During pregnancy and postpartum, it is fundamental to investigate suicide risk, including suicidal ideation, thoughts, and intent, especially (but not only) in women affected by mental pathology. Moreover, maternal suicide behaviour affects the child’s neuropsychological development and can also increase the infant´s suicide risk.

The lifetime prevalence of comorbid posttraumatic stress disorder (PTSD) in patients with bipolar disorder (BD) is approximately 20%. Guidelines for BD give adequate pharmacological treatment options when there is a ‘pure’ bipolar disorder but lack of treatment options when there is a comorbid disorder present.

The present study aimed to review the pharmacological treatment options for comorbid PTSD in patients with BD.

Literature research was conducted via PubMed, Embase and the Cochrane Library. Search terms included ‘bipolar disorder’, ‘posttraumatic stress disorder’, ‘PTSD’, ‘pharmacotherapy’ and ‘treatment’. Relevant studies were reviewed.

No randomized controlled trials have been conducted in patients with bipolar disorder and comorbid PTSD. Most studies included open-label studies and case-reports. No convincing scientific evidence for pharmacological treatment of comorbid PTSD in patients with BD was found. Selective serotonin reuptake inhibitors (SSRIs) are effective in the treatment of PTSD. However, SSRIs or other antidepressants are complicated due to potential induction of a manic episode or promote rapid cycling. Nevertheless, it is important to treat the bipolar patient with a mood stabilizer first before antidepressants are prescribed.

The findings of this study show that there is no convincing scientific evidence for the pharmacological treatment of comorbid PTSD in patients with bipolar disorder. Therefore, psychotherapy is preferable. When psychotherapy is not effective, pharmacotherapy can be considered. However, randomized controlled trials are needed to obtain scientific evidence for pharmacological treatment options.

Suicide rates in people diagnosed with a psychotic disorder can be up to 50 times higher than in the general population, with the lethality of attempts being significantly higher in this group, compared to people diagnosed with other psychiatric disorders. Furthermore, it is known that being male is associated with more serious suicide attempts and higher rates of completed suicides.

To reflect on the increased risk of suicide associated with psychotic disorders.

Case report and literature review.

Case report 40-year-old male, recently diagnosed with Schizophreniform Disorder and currently with persistent positive symptoms. He was admitted to our psychiatric hospitalization unit due to a voluntary overdose of almost 100 tablets (antihypertensives, antiarrhythmics, and benzodiazepines) and alcohol. He admits taking the pills with the aim of committing suicide. Literature review: - Around 10% of people diagnosed with schizophrenia commit suicide. - In young patients diagnosed with schizophrenia, suicide is the leading cause of death. - Between 15 and 65% of patients diagnosed with schizophrenia have depressive symptoms such as hopelessness. - Depressive symptoms in these patients seem to be directly proportionally with awareness of the disease (stigma, awareness of its severity and a sudden decrease in quality of life and social integration). - The risk of suicide increases especially in the first 10 years of the disease.

Psychosis is an important risk factor of suicide and active preventive measures should be carried out in these patients.

While it is well known that there is an interaction between sleep disorders and substance abuse, it is certainly more complex than was previously thought. The effects on sleep depend on the substance used, but it has been shown that both during use and in withdrawal periods consumers have various sleep problems, and basically more fragmented sleep. We know that sleep problems must be taken into account to prevent addiction relapses.

To explain the different sleep disorders caused by substances such as alcohol and cannabis

As an example of this, two cases are introduced: the first one, a 17-year-old boy, who is diagnosed with ADHD with daily cannabis use since the age of 14. As a result of reducing consumption, he presents an episode of sleep paralysis that he had not previously had. The second one is a 50-year-old man diagnosed with a personality disorder and with dependence on cannabis and alcohol for years. He currently has abstinence from alcohol for months and maintains daily cannabis use. However, he has long-standing sleep pattern disturbances and frequent depersonalization phenomena at night.

Alcohol at low doses has no clear effects on sleep architecture. At higher doses it decreases sleep latency, as well as awakenings. In chronic alcoholic patients, a decrease in deep slow sleep, and more fragmented sleep have been found. Cannabis withdrawal reduces sleep quality, increases latency, and produces strange dreams.

There is a positive relationship both between having a substance use disorder and suffering from a sleep disorder.

Traditional categorical classifications of personality disorders (PD) have been criticized for insufficient structural and cross-cultural validity. In the DSM-5 Section III, alternative model of the PDs (AMPD), the maladaptive personality traits are divided into five domains: negative affect, detachment, antagonism, disinhibition and psychoticism. The Personality Inventory for DSM-5 Brief Form (PID-5-BF) is a 25-item self-report questionnaire that measures the severity of each of these five domains. To date, no questionnaires assessing pathological personality traits following the AMPD have been validated in Russia.

This study aimed to investigate the factor structure of the Russian version of PID-5-BF.

Five hundred and 86 (female - 505 (86,2%), age - 18–77 years (M - 28.2, SD - 11.5)) consecutive inpatients with non-psychotic mental disorders were assessed with the Russian language version of the PID-5-BF. Exploratory structural equation modelling (ESEM) with Robust Diagonally Weighted Least Squares method of extraction and Robust Equamax rotation was performed in Factor v 11.04.02.

The results of the ESEM analysis showed good fit of the five-factor model (CFI - 0.982; TLI - 0.971; RMSEA (95% CI) - 0.036 (0.01-0.05). Most of the items had the highest factor loadings on their mother domains. However, two items showed weak loadings on their designated factors (<0.4), and attention seeking item had a primary load to (low) detachment instead of antagonism.

The PID-5-BF was found to be a valid and reliable tool for the evaluation of the AMPD trait domain
