First Episode Psychosis Following COVID-19 Vaccination: a Case Report.

Vaccines are crucial to ending the COVID-19 pandemic. An mRNA-based COVID-19 vaccine can cause mild to moderate side effects. A number of cases of cardiac, gastrointestinal, and psychiatric side effects have been reported as rare side effects associated with the COVID-19 vaccine. This article presents a patient, who after the second injection of the mRNA-based COVID-19 vaccine, immediately developed anxiety, nonspecific fear, and insomnia as the prodromal phase of psychosis. Starting from the second week, the patient manifested delusions of persecution, delusions of influence, thoughts insertion, and delusional behaviour, culminating in the suicide attempt. The duration of psychosis was eight weeks, and symptom reduction was observed only after the gradual administration of antipsychotics over four weeks. The investigations of the patient did not support any structural changes of the brain, any severe medical conditions, a neurological abnormality, a confusion or a state of unconsciousness or alterations in laboratory tests. Psychosis due to the use of alcohol or psychoactive substances was excluded. The psychological assessment of the patient demonstrated the endogenous type of thinking, and the patient had schizoid and paranoid personality traits strongly associated with schizophrenia. This case indicates a strong causal relationship between the mRNA-based COVID-19 vaccine injection and the onset of psychosis. We intend to follow up this case for possible development of schizophrenia and understand that the COVID-19 vaccine could possible play a trigger role in the development of primary psychosis. Longer-term supporting evidence is needed to estimate the prevalence of psychosis following vaccination with the mRNA-based COVID-19 vaccine.

Determinants of Anxiety in the General Latvian Population During the COVID-19 State of Emergency.

Background: The COVID-19 pandemic and its restrictive public health measures have seriously affected mental health of society. Social, psychological, and health-related factors have been linked to anxiety in the general population. Aim: We investigate the association of various sociopsychological and health-related determinants of anxiety and identify the predicting factors for anxiety in the general population during the COVID-19 state of emergency from in Latvia. Methods: We conducted an online survey using a randomized stratified sample of the general adult population in July 2020 for 3 weeks. Anxiety symptoms were measured using the State-Trait Anxiety Inventory (STAI-S). Sociodemographic, health-related, sociopsychological characteristics and suicidality were identified using the structured questionnaire. The statistical analysis included Pearson's chi-square test, post hoc analysis, and binomial logistic regression. Results: The weighted study sample included 2,608 participants. The mean STAY-S score of the total sample was 22.88 ± 12.25. In the total sample, 15.2% (n = 398) of participants were classified as having anxiety. The odds ratio (OR) of having anxiety was higher in females (OR = 2.44; 95% CI 1.75-3.33) and people who had experienced mental health problems in the past (OR = 1.45; 95% CI 1.03-2.04), had suicide attempt in the past (OR = 1.68; 95% CI 1.08-2.59), were worried about their health status due to COVID-19 (OR = 1.64; 95% CI 1.36-1.16), were worried about stigmatization from others if infected with COVID-19 (OR = 1.18; 95% CI 1.03-1.35), were worried about information regarding COVID-19 from the Internet (OR = 1.24; 95% CI 1.08-1.43), persons who were lonely (OR = 1.90; 95% CI 1.54-2.34), and persons with negative problem orientation (OR = 1.26; 95% CI 1.06-1.51). Protective factors were identified as having good self-rated general health (OR = 0.68, 95 % CI 0.58-0.81), maintaining a daily routine (OR = 0.74, 95 % CI 0.61-0.90), having financial stability (OR = 0.66, 95 % CI 0.55-0.79), and having good psychological resilience (OR = 0.90, 95 % CI 0.87-0.94). Conclusions: This is the first study to report a prevalence of anxiety in the general population of Latvia. Certain factors that predict anxiety, as well as protective factors were identified.

Characterisation of a conspiracy believers and their mental health during the COVID-19 emergency state in Latvia.

BACKGROUND: A wave of believers in conspiracies has emerged amid the COVID-19 crisis. The purpose of this study was to characterise an individual who believes in conspiracies and to discover whether believing in them is associated with mental health. METHODS: Data was collected as an online survey in a randomised, stratified cohort in July 2020 as a part of the National Research Program of Latvia. The precisely selected and segmented database corresponding to the general population of Latvia was used. Non-parametric tests to compare medians and Spearman correlation to measure the strength of the relationship were applied. RESULTS: The weighted study sample consisted of 2608 participants. A positive correlation was detected between age and belief in conspiracies among females (r = 0.061; p = 0.017). Median conspiracy theory points were significant as follows: individuals who have primary or high school education (p < 0.001) rather than higher education; females (p < 0.001) who resided in a town (p < 0.001) as opposed to occupying the capital; divorcees (p = 0.022) in contrast with those being in a relationship; along with those being unemployed (p < 0.001) compared to the employed, or students. Depressed respondents more often than healthy individuals believed that COVID-19 was created in a laboratory (p < 0.05), that this virus is a result of a 5G antenna (p < 0.05) and that it is a sign of divine power to destroy our planet (p = 0.001). CONCLUSION: The important messages conveyed to the public should be reviewed so that they are more relatable and comprehensible. Furthermore, additional attention should be paid to critical thinking in education programs.

Factors Related to COVID-19 Preventive Behaviors: A Structural Equation Model.

Background: While COVID-19 has rapidly spread around the world, and vaccines are not widely available to the general population, the World Health Organization outlines preventive behavior as the most effective way to limit the rapid spread of the virus. Preventive behavior is associated with a number of factors that both encourage and discourage prevention. Aim: The aim of this research was to study COVID-19 threat appraisal, fear of COVID-19, trust in COVID-19 information sources, COVID-19 conspiracy beliefs and the relationship of socio-demographic variables (gender, age, level of education, place of residence, and employment status) to COVID-19 preventive behavior. Methods: The data originate from a national cross-sectional online survey (N = 2,608) undertaken in July 2020. The data were analyzed using structural equation modeling. Results: COVID-19 threat appraisal, trust in COVID-19 information sources, and fear of COVID-19 are all significant predictors of COVID-19 preventive behaviors. Together they explain 26.7% of the variance of this variable. COVID-19 conspiracy beliefs significantly negatively predict COVID-19 threat appraisal (R 2 = 0.206) and trust in COVID-19 information sources (R 2 = 0.190). COVID-19 threat appraisal contributes significantly and directly to the explanation of the fear of COVID-19 (R 2 = 0.134). Directly, as well as mediated by COVID-19 conspiracy beliefs, threat appraisal predicts trust in COVID-19 information sources (R 2 = 0.190). The relationship between COVID-19 threat appraisal and COVID-19 preventive behaviors is partially mediated by fear of COVID-19 (indirect effect 28.6%) and trust in information sources (15.8%). Socio-demographic variables add very little in prediction of COVID-19 preventive behavior. Conclusions: The study results demonstrate that COVID-19 threat appraisal is the most important factor associated with COVID-19 preventive behavior. Those Latvian residents with higher COVID-19 threat appraisal, experienced higher levels of fear of COVID-19, had more trust in COVID-19 information sources, and were more actively involved in following COVID-19 preventive behaviors. COVID-19 conspiracy beliefs negatively predict COVID-19 threat appraisal and trust in COVID-19 information sources, but not the COVID-19 preventive behaviors. Socio-demographic factors do not play an important role here.

Factors related to depression, distress, and self-reported changes in anxiety, depression, and suicidal thoughts during the COVID-19 state of emergency in Latvia.

PURPOSE: Evidence suggests that the 2020 COVID-19 pandemic might have deleterious effects on the population's mental health and psychiatric outcomes. We examined the prevalence of depression, distress, and suicidal thoughts and their association with social and economic factors during the state of emergency in a nationwide representative sample of the general population in Latvia. MATERIALS AND METHOD: An online survey was conducted using a randomized stratified sample of the general adult population in July 2020 for 3 weeks. Distress, depression, suicidal thoughts, and self-reported changes in mental health were identified using a structured questionnaire. The statistical analysis included chi-square tests, analyses of variance, and multivariate forward-stepwise linear regressions. RESULTS: The study sample included 2608 respondents. Clinical depression was present in 5.75% and distress in 7.82%. Suicidal thoughts increased in 13.30% of those with a history of clinical depression, and 27.05% of those with a history of suicidal attempts. The variables that were associated with increases in self-reported anxiety, depressive thoughts, suicidal ideation, and being currently depressed/distressed included lower general health, increased fears of contracting COVID-19 or having family members contract it and die, history of suicidality, increased family conflicts, decreased religiosity, caring for a vulnerable person. Protective factors included positive changes in family relationships and economic situation, maintaining one's basic routine, and having more people living in the household. CONCLUSIONS: Further research and interventions should focus specifically on these factors. The study's findings can help to develop future strategies for management of psychological support for different groups in general population.
