Self-evaluated anxiety in the Norwegian population: prevalence and associated factors

Prevalence of psychological distress in nurses, physicians and leaders working in intensive care units during the COVID-19 pandemic: a national one-year follow-up study

OBJECTIVE

To report and compare psychological distress as symptoms of anxiety, depression and post-traumatic stress among intensive care units' (ICU) nurses, physicians and leaders at 12 months after the baseline survey (spring 2020), during the COVID-19 pandemic in Norway. Furthermore, to analyse which baseline demographic and COVID ICU-related factors have a significant impact on psychological distress at 12 months.

DESIGN

Prospective, longitudinal, observational cohort study.

SETTING

Nationwide, 27 of 28 hospitals with COVID ICUs in Norway.

PARTICIPANTS

Nurses, physicians and their leaders. At 12 month follow-up 287 (59.3%) of 484 baseline participants responded.

PRIMARY AND SECONDARY OUTCOME MEASURES

Symptoms of anxiety and depression using the Hopkins Symptoms Checklist-10 (HSCL-10). Symptoms of post-traumatic stress using the post-traumatic stress disease checklist for the Diagnostic and Statistical Manual of Mental Disorders 5 (PCL-5).Demographics (included previous symptoms of anxiety and depression) and COVID ICU-related factors (professional preparations, emotional experience and support) impacting distress at 12 months.

RESULTS

Psychological distress, defined as caseness on either or both HSCL-10 and PCL-5, did not change significantly and was present for 13.6% of the participants at baseline and 13.2% at 12 month follow-up. Nurses reported significantly higher levels of psychological distress than physicians and leaders. Adjusted for demographics and the COVID ICU-related factors at baseline, previous symptoms of depression and fear of infection were significantly associated with higher levels of anxiety and depression at 12 months. Previous symptoms of depression, fear of infection and feeling of loneliness was significantly associated with more symptoms of post-traumatic stress.

CONCLUSION

One year into the COVID-19 pandemic 13.2% of the ICUs professionals reported psychological distress, more frequently among the nurses. Fear of infection, loneliness and previous symptoms of depression reported at baseline were associated with higher levels of distress. Protective equipment and peer support are recommended to mitigate distress.

Psychological responses and associated factors during the initial lockdown due to the corona disease epidemic (COVID-19) among Norwegian citizens

BACKGROUND

Ongoing COVID-19 studies pay little attention to the risk or protective factors related to psychological stress.

AIMS

This study aims to estimate the prevalence of anxiety, depression and insomnia during the initial phase of the COVID-19 outbreak, and explore factors that might be associated with these outcomes.

METHODS

A population-based cross-sectional survey was conducted using snowball-sampling strategy. Participants from 18 years or older filled out an anonymous online questionnaire.

RESULTS

A total of 4527 citizens filled out the questionnaire. Prevalence rates were; insomnia 31.8%, anxiety 17.1% and depression 12.5%. Risk factors associated with anxiety, depression and insomnia were being single (OR = 0.75, OR = 0.57, OR = 0.59), unemployed (OR = 0.47, OR = 0.53, OR = 0.73), financial concerns (OR = 1.66, OR = 2.09, OR = 1.80) at risk for complication from COVID-19 (OR = 1.63, OR = 1.68, OR = 1.60), and being generally worried due to the COVID-19 (OR 0 3.06, OR = 1.41, OR = 1.74).

CONCLUSION

Being single, unemployed, at risk of health complications, or having concerns because of financial or other consequences of the pandemic are associated with mental health adversities such as anxiety, depression and insomnia during a pandemic lockdown.

High Perceived Stress and Low Self-Efficacy are Associated with Functional Somatic Disorders: The DanFunD Study

Objective

Several psychological factors have been proposed to be associated with functional somatic disorders (FSD) including functional somatic syndromes, such as irritable bowel, chronic widespread pain, and chronic fatigue. However, large randomly selected population-based studies of this association are sparse. This study aimed to investigate the association between FSD and perceived stress and self-efficacy, respectively, and to investigate if FSD differed from severe physical diseases on these aspects.

Methods

This cross-sectional study included a random sample of the adult Danish population (n = 9656). FSD were established using self-reported questionnaires and diagnostic interviews. Perceived stress was measured with Cohen's Perceived Stress Scale and self-efficacy with the General Self-Efficacy Scale. Data were analysed with generalized linear models and linear regression models.

Results

FSD were associated with higher perceived stress and lower self-efficacy, especially for the multi-organ and the general symptoms/fatigue FSD types and for chronic fatigue. However, controlling for the personality trait neuroticism altered the associations with self-efficacy so it became insignificant. The analysis did not support an important interaction between perceived stress and self-efficacy on the likelihood of having FSD. Individuals with FSD presented levels of perceived stress that were not equal, ie higher, to those in individuals with severe physical diseases.

Conclusion

FSD were positively associated with perceived stress and negatively associated with self-efficacy. Our study may point to stress being part of the symptomatology of FSD. This underlines the severity of having FSD and stresses the relevance of the resilience theory in the understanding of the condition.

Prevalence of anxiety disorders and association to socioeconomic position. Results from the Lolland Falster Health Study

PURPOSE

The purpose of this study is to describe the prevalence of anxiety disorders in a general population and the association to socioeconomic position (SEP), which has not been described in a Danish context before.

MATERIAL AND METHODS

We present data on anxiety symptoms from respondents in the rural-provincial Lolland-Falster population Health Study (LOFUS). Analyses of the questionnaire responses to the Anxiety Symptom Scale were done by descriptive statistics and logistic regression analyses adjusted for sex and age.

RESULTS

14,834 LOFUS respondents who completed the Anxiety Symptom Scale were included; According to the original algorithm 371 (2.5%) had an anxiety disorder. The adjusted odds ratios (aOR) for anxiety disorder were strongly associated to SEP. We found aOR for anxiety to be: 3.8 (confidence interval (CI 95%) 2.54 - 5.92) for respondents with no postsecondary education compared to those with 3+ years of postsecondary education; 11.9 (CI 8.89 - 16.01) for respondents temporarily out of a job compared to those working; 9.4 (CI 6.06 - 14.51) for those experiencing constant financial strain compared to those not experiencing financial strain. Relaxing the criteria for anxiety to item 10 > 1, the prevalence raised to 3.9%. The association was unchanged related to education; however, the aOR dropped to 9 and 8 respectively, for being temporally out of job, or in financial strain every month- when doing same comparisons.

CONCLUSIONS

The 14-day prevalence of anxiety disorder seems low but strongly associated to SEP especially for individuals temporarily out of a job or experiencing financial strain.

A cross-sectional study of mental health-, posttraumatic stress symptoms and post exposure changes in Norwegian ambulance personnel

Background

Posttraumatic stress disorder (PTSD) has been shown to be elevated among first responders (Emergency Medical Services, fire service, police force) compared to the general population. Examining the prevalence of mental health issues in a work force with an elevated occupational risk is fundamental towards ensuring their wellbeing and implementing safeguard measures. The goal of this study is therefore to report the prevalence of depression, anxiety, posttraumatic development, and PTSD in Norwegian ambulance personnel.

Methods

This study is a cross-sectional, anonymous, web-based survey (Questback®), performed among operative personnel employed in the Emergency Medical Services in the Regional Health Trust of Central Norway between 18. February and 9. April 2021. The study was sent to 1052 eligible participants. Questions reported demographic data, a traumatic events exposure index, Patient Health Questionnaire-9 (Depression), Generalized Anxiety Disorder-7 scale, Posttraumatic symptom scale (PTSD) and Posttraumatic change scale.

Results

The response rate in this study was 45.5% (n = 479/1052). The mean age of respondents was 37.1 years (std. 11.1) and 52.8% (n = 253) were male. Of the respondents, 80.6% (n = 386) were married or had a partner, and 91.6% (n = 439) reported having access to a peer support programme, with 34.9% (n = 167) reporting that they had utilized peer support. In this study, 5% (n = 24) showed a prevalence of manifest posttraumatic stress disorder symptoms, while 8.6% (n = 41) reported moderate to severe depression and 2.9% (n = 14) presented moderate to severe symptoms of general anxiety. Of the respondents, 77.2% (n = 370) reported personal growth because of their work experiences.

Conclusions

This study indicates that Norwegian ambulance personnel report a prevalence of posttraumatic stress symptoms and depression, which is slightly higher for men, and lower for the female proportion in this study, when compared to an adult Norwegian population. The vast majority of respondents reported personal growth because of their work experience, and both the degree of peer support and having a partner seem to influence levels of posttraumatic stress and -development.

Cross-National Study of Worrying, Loneliness, and Mental Health during the COVID-19 Pandemic: A Comparison between Individuals with and without Infection in the Family

Objective: The objective of this study was to examine differences in worry, loneliness, and mental health between those individuals infected by COVID-19 or having someone their family infected, and the rest of the population. Methods: A cross-sectional online survey was conducted in Norway, UK, USA, and Australia during April/May 2020. Participants (n = 3810) were recruited via social media postings by the researchers and the involved universities. Differences between those with and without infection in the family were investigated with chi-square tests and independent t-tests. Multiple regression analyses were used to assess associations between sociodemographic variables and psychological outcomes (worry, loneliness, and mental health) in both groups. Results: Compared to their counterparts, participants with infection in the family reported higher levels of worries about themselves (p < 0.05) and their family members (p < 0.001) and had poorer mental health (p < 0.05). However, the effect sizes related to the differences were small. The largest effect (d = 0.24) concerned worries about their immediate family. Poorer psychological outcomes were observed in those who were younger, female, unemployed, living alone and had lower levels of education, yet with small effect sizes. Conclusions: In view of the small differences between those with and without infection, we generally conclude that the mental health effects of the COVID-19 situation are not limited to those who have been infected or have had an infection within the family but extend to the wider population.

Psychological distress and its associations with psychosocial work environment factors in four professional groups: A cross-sectional study

This study aimed to explore associations between psychosocial work environment factors and psychological distress in four groups of professionals in Norway. Eight hundred fifty-six professionals participated in this cross-sectional study 6 years after graduation. Data were analyzed with linear and logistic regression analyses. For the sample as a whole, higher psychological distress was associated with higher demands, lower support, lower job satisfaction, more work-home interaction problems, and lower coping in the job. Work-home interaction problems increased the likelihood of having case-level psychological distress. The strength of associations between psychological distress and other factors, such as demands, support, and coping in the job, varied by professional group. In conclusion, problems concerned with work-home interaction were generally associated with higher psychological distress. Between professional groups, other independent variables were differently associated with psychological distress. Work environment factors should receive continued attention in efforts to promote mental health.

State anxiety influences P300 and P600 event-related potentials over parietal regions in the hollow-mask illusion experiment

The hollow-mask illusion is an optical illusion where a concave face is perceived as convex. It has been demonstrated that individuals with schizophrenia and anxiety are less susceptible to the illusion than controls. Previous research has shown that the P300 and P600 event-related potentials (ERPs) are affected in individuals with schizophrenia. Here, we examined whether individual differences in neuroticism and anxiety scores, traits that have been suggested to be risk factors for schizophrenia and anxiety disorders, affect ERPs of healthy participants while they view concave faces. Our results confirm that the participants were susceptible to the illusion, misperceiving concave faces as convex. We additionally demonstrate significant interactions of the concave condition with state anxiety in central and parietal electrodes for P300 and parietal areas for P600, but not with neuroticism and trait anxiety. The state anxiety interactions were driven by low-state anxiety participants showing lower amplitudes for concave faces compared to convex. The P300 and P600 amplitudes were smaller when a concave face activated a convex face memory representation, since the stimulus did not match the active representation. The opposite pattern was evident in high-state anxiety participants in regard to state anxiety interaction and the hollow-mask illusion, demonstrating larger P300 and P600 amplitudes to concave faces suggesting impaired late information processing in this group. This could be explained by impaired allocation of attentional resources in high-state anxiety leading to hyperarousal to concave faces that are unexpected mismatches to standard memory representations, as opposed to expected convex faces.

The effects of intensive home treatment on self-efficacy in patients recovering from a psychiatric crisis

Background

This study evaluated whether providing intensive home treatment (IHT) to patients experiencing a psychiatric crisis has more effect on self-efficacy when compared to care as usual (CAU). Self-efficacy is a psychological concept closely related to one of the aims of IHT. Additionally, differential effects on self-efficacy among patients with different mental disorders and associations between self-efficacy and symptomatic recovery or quality of life were examined.

Methods

Data stem from a Zelen double consent randomised controlled trial (RCT), which assesses the effects of IHT compared to CAU on patients who experienced a psychiatric crisis. Data were collected at baseline, 6 and 26 weeks follow-up. Self-efficacy was measured using the Mental Health Confidence Scale. The 5-dimensional EuroQol instrument and the Brief Psychiatric Rating Scale (BPRS) were used to measure quality of life and symptomatic recovery, respectively. We used linear mixed modelling to estimate the associations with self-efficacy.

Results

Data of 142 participants were used. Overall, no difference between IHT and CAU was found with respect to self-efficacy (B = − 0.08, SE = 0.15, p = 0.57), and self-efficacy did not change over the period of 26 weeks (B = − 0.01, SE = 0.12, t (103.95) = − 0.06, p = 0.95). However, differential effects on self-efficacy over time were found for patients with different mental disorders (F(8, 219.33) = 3.75, p < 0.001). Additionally, self-efficacy was strongly associated with symptomatic recovery (total BPRS B = − 0.10, SE = 0.02, p < 0.00) and quality of life (B = 0.14, SE = 0.01, p < 0.001).

Conclusions

Although self-efficacy was associated with symptomatic recovery and quality of life, IHT does not have a supplementary effect on self-efficacy when compared to CAU. This result raises the question whether, and how, crisis care could be adapted to enhance self-efficacy, keeping in mind the development of self-efficacy in depressive, bipolar, personality, and schizophrenia spectrum and other psychotic disorders. The findings should be considered with some caution. This study lacked sufficient power to test small changes in self-efficacy and some mental disorders had a small sample size.

Post-Traumatic Stress Disorder and Associated Factors during the Early Stage of the COVID-19 Pandemic in Norway

The COVID-19 outbreak and the sudden lockdown of society in March 2020 had a large impact on people’s daily life and gave rise to concerns for the mental health in the general population. The aim of the study was to examine post-traumatic stress reactions related to the COVID-19 pandemic, the prevalence of symptom-defined post-traumatic stress disorder (PTSD), and factors associated with post-traumatic stress in the Norwegian population during the early stages of the COVID-19 outbreak. A survey was administered via social media channels, to which a sample of 4527 adults (≥18 years) responded. Symptom-defined PTSD was measured with the PTSD Checklist for the DSM-5. The items were specifically linked to the COVID-19 pandemic. We used the DSM-5 diagnostic guidelines to categorize participants as fulfilling the PTSD symptom criteria or not. Associations with PTSD were examined with single and multiple logistic regression analyses. The prevalence of symptom-defined PTSD was 12.5% for men and 19.5% for women. PTSD was associated with lower age, female gender, lack of social support, and a range of pandemic-related variables such as economic concerns, expecting economic loss, having been in quarantine or isolation, being at high risk for complications from COVID-19 infection, and having concern for family and close friends. In conclusion, post-traumatic stress reactions appear to be common in the Norwegian population in the early stages of the COVID-19 outbreak. Concerns about finances, health, and family and friends seem to matter.

COVID-19 and psychological distress in Norway: The role of trust in the healthcare system

Aim:

The study aims to examine groups at risk for psychological distress in connection with the COVID-19 outbreak, and the role of trust in the healthcare system as a possible moderator.

Methods:

Data were collected from a large sample of the Norwegian population (n = 4008) through the Norwegian Citizen Panel (NCP). A linear regression was conducted to examine the effects of COVID-19 related risk factors on psychological distress, using the 10-item Hopkins Symptom Checklist (HSCL-10). Finally, we conducted a moderation analysis to examine the interaction of trust in the healthcare system and COVID-19 related risk factors.

Results:

A linear regression showed that female gender, younger age, lower level of education, being infected with COVID-19, being medically vulnerable, working in the healthcare system, being in voluntary quarantine and having an immigrant background predicted mean HSCL-10 scores. The moderation analysis revealed that people in the medically vulnerable group, those below 61, and those in quarantine reported higher psychological distress when they also had lower trust in the healthcare system.

Conclusions:

Findings indicate important groups to take into consideration in mental healthcare strategies and policies. However, most participants in the current study reported psychological distress levels that were below the clinical cut-off, suggesting that the majority may have coped relatively well in the early stages of the pandemic.

Variations in psychiatric morbidity between traumatized Norwegian, refugees and other immigrant patients in Oslo

Background: There is a lack of clinical studies that focus on different psychiatric disorders after trauma and the relationship with migration status.Purpose: To examine differences in psychiatric morbidity in traumatized patients referred to psychiatric treatment in Southern Oslo.Materials and methods: Hundred and ten patients with trauma background attending an outpatient clinic in Southern Oslo were studied. Forty-four of the participants (40%) were ethnic Norwegians, 25 (22.7%) had refugee background and 41 (37.3%) were first- or second-generation immigrants without refugee background. Thorough diagnostic assessment was done by experienced psychiatrists through several structured clinical interviews and self-report questionnaires.Results: Ninety-eight patients (89%) were diagnosed with at least one Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) disorder. There was a clear difference in the presentation of certain psychiatric disorders between the groups. Ethnic Norwegian patients were more likely to have anxiety disorders: agoraphobia, social phobia and panic disorder than non-refugee immigrant patients. They also had higher rates of alcohol abuse/dependence. Somatoform pain disorder was more common in both the refugee and other-immigrant groups than among the ethnic Norwegian patients. The refugee patients had significantly more major depressive disorder, post-traumatic stress disorder (PTSD) and both co-occurring.Conclusion: Trauma is frequently associated with depression, anxiety disorders, somatoform pain disorder and PTSD in a clinical population. The clinical presentation and comorbidity of these disorders seem to vary significantly between traumatized patients with Norwegian, refugee and non-refugee immigrant backgrounds. After a major trauma, refugees may be at greater risk for both PTSD and depression than other immigrants and the native population.

Psychotropic effects of L-theanine and its clinical properties: From the management of anxiety and stress to a potential use in schizophrenia

Anxiety disorders are highly prevalent in modern societies, and are ranked the sixth most important contributor of non-fatal negative health outcomes. _L-theanine is an amino acid naturally found in green tea (Camellia sinensis) and some other plant extracts, and recent clinical studies have proposed promising adjuvant effects of _L-theanine for the negative impact of anxiety and psychological stress on health. In this integrative narrative review, we aimed to appraise and further discuss the effects of _L-theanine administration on anxiety disorders and psychological stress. Published data suggests that _L-theanine administered at daily doses ranging from 200 to 400 mg for up to 8 weeks are safe and induce anxiolytic and anti-stress effects in acute and chronic conditions. _L-theanine at doses lower and higher than these may also show promising therapeutic potential; however, a more thorough investigation through randomized double-blind placebo-controlled crossover clinical trials are necessary to elucidate its effects for longer periods, providing further insights for meta-analyses and the development of recommendation guidelines. Additionally, animal studies investigating a higher dosage, its combination with other pharmacological compounds and associated metabolic comorbidities are recommended, as cases of hepatotoxicity associated with the consumption of green tea extract have been reported.
