The Influence of the Big Five Personality Factors on Mental Health Before and During the COVID-19 Pandemic: A Prospective Study.

The Big Five personality factors (PF) are considered to be predictive of mental health problems, but it is unclear if these factors equally contributed to mental health problems during the COVID-19 pandemic compared to before the pandemic. This prospective study aimed to fill this knowledge gap. For this purpose data was extracted from the population-based LISS-panel.

The effects of potentially traumatic events on the recovery from pre-existing anxiety and depression symptomatology and the risk of PTSD.

Aim: The extent to which recent potentially traumatic events (PTEs) hinder the recovery from pre-existing mental health problems is largely unknown. The same applies to the extent to which non-recovery from pre-existing mental health problems increases the risk of posttraumatic stress disorder (PTSD). The aim of the present study is to gain insight in these effects.

Data of the multi-wave population-based prospective Victims in Modern Society (VICTIMS) study on potential traumatic events, social support, mental health, coping self-efficacy and services use.

We present the data of the first six annual surveys of the large prospective population-based Dutch VICTIMS-study that started in 2018. Each survey systematically examines exposure to potential traumatic events in the past 12 months, including time of event and amount of stress during the event. Furthermore, each survey assesses anxiety and depression symptomatology, lack of social support, physical, mental, work, partner/family, religious, legal, administrative and financial problems, and problem-related services use.

The prevalence of anxiety and depression symptoms (ADS), persistent and chronic ADS among the adult general population and specific subgroups before and during the COVID-19 pandemic until December 2021.

Background: It is unclear to what extent the prevalence of moderate and severe anxiety and depression symptoms (ADS) is higher during the first 20 months after the COVID-19 outbreak than before the outbreak. The same holds for persistent and chronic ADS among the adult general population and subgroups (such as employed, minorities, young adults, work disabled).

Methods: Data were extracted from six surveys conducted with the Dutch longitudinal LISS panel, based on a traditional probability sample (N = 3493).

The impact of pre- and post-trauma financial problems on posttraumatic stress symptoms, anxiety and depression symptoms, and emotional support: A prospective population-based comparative study.

Potentially traumatic events (PTEs) are associated with a higher risk of mental health problems and a lack of emotional support. The extent to which pre- and/or post-trauma financial problems further increase this risk, while controlling for pre-trauma mental health problems and lack of support and compared to nonvictims, is largely unknown. To better understand this risk, data was extracted from four surveys of VICTIMS study using the Dutch population-based longitudinal LISS-panel.

Validation of the 2 × 24 h recall method and a 7-d web-based food diary against doubly labelled water in Danish adults.

The European Food Safety Authority has suggested that EU countries implement the 2 × 24 h diet recall (2 × 24 h DR) method and physical activity (PA) measurements for national dietary surveys. Since 2000, Denmark has used 7 d food diaries (7 d FD) with PA questionnaires and measurements. The accuracy of the reported energy intakes (EI) from the two diet methods, pedometer-determined step counts and self-reported time spent in moderate-to-vigorous PA (MVPA) were compared with total energy expenditure measured by the doubly labelled water (TEEDLW) technique and with PA energy expenditure (PAEE), respectively.

To what extent do post-traumatic mental health and other problems reflect pre-existing problems? Findings from the prospective comparative population-based VICTIMS-study.

Background: Findings from prospective studies question the assumption that mental health problems observed in traumatized adults mainly reflect the effects of potentially traumatic events.

Aims: Aim of the present comparative prospective study is to clarify the extent to which victims of potentially traumatic events with mental health, social, financial, and/or legal problems, already suffered from such problems before these events.

Method: Data was extracted from three surveys of the prospective VICTIMS-study (T1 = 2018, T2 = 2019, T3 = 2020), conducted with the population-based longitudinal LISS-panel.

Social network responses to victims of potentially traumatic events: A systematic review using qualitative evidence synthesis.

Background: A substantial number of qualitative studies examined how adult victims of potentially traumatic events (PTEs) experienced support provided by family members, friends, colleagues, and other significant others in the informal network. Importantly, the large majority of qualitative studies focused on the perceived support of victims of specific events such as sexual offences, partner violence, homicide, accidents and disasters. Although it is likely that across specific PTEs there are similarities as well as differences in experienced support from the informal network, to date no systematic review synthesized the results of qualitative studies on support from the informal network following various types of PTEs.

Increasing the Sales of Suboptimal Foods with Sustainability and Authenticity Marketing Strategies.

To reduce food waste, it is essential to motivate consumers to purchase and consume products that deviate from optimality on the basis of only cosmetic specifications (also called suboptimal products). Previous research has shown it to be challenging to motivate consumers to buy such suboptimal products. Sustainability or authenticity positioning of suboptimal products may be a promising avenue, but no research to date has examined their effects on consumer .

The prevalence, incidence, and risk factors of mental health problems and mental health service use before and 9 months after the COVID-19 outbreak among the general Dutch population. A 3-wave prospective study.

Objectives: Gain insight into the effects of the COVID-19 pandemic on the prevalence, incidence, and risk factors of mental health problems among the Dutch general population and different age groups in November-December 2020, compared with the prevalence, incidence, and risk factors in the same period in 2018 and 2019. More specifically, the prevalence, incidence, and risk factors of anxiety and depression symptoms, sleep problems, fatigue, impaired functioning due to health problems, and use of medicines for sleep problems, medicines for anxiety and depression, and mental health service.

Methods: We extracted data from the Longitudinal Internet studies for the Social Sciences (LISS) panel that is based on a probability sample of the Dutch population of 16 years and older by Statistics Netherlands.

Mental health problems among Dutch adolescents of the general population before and 9 months after the COVID-19 outbreak: A longitudinal cohort study.

The aim of the present study is to examine whether the COVID-19 pandemic has increased the risk of mental health problems (MHP) in adolescents nine months post-outbreak. For this purpose, a longitudinal cohort study was conducted based on a probability sample of the Dutch population. We compared the prevalence and incidence of MHP in 16-20 year-old adolescents in November-December 2020 (N = 251) with the prevalence and incidence in adolescents in November-December 2012 (N = 346) and November-December 2016 (N = 253).

Differences in mental health problems, coping self-efficacy and social support between adults victimised before and adults victimised after the COVID-19 outbreak: population-based prospective study.

Background: Victims of violence, accidents and threats are at risk for mental health problems. Lower coping self-efficacy and social support levels increase this risk. Although highly relevant, it is unknown if the coronavirus disease 2019 (COVID-19) pandemic amplifies these risks.

The use of professional help and predictors of unmet needs for dealing with mental health to legal problems among victims of violence, accidents, theft and threat, and nonvictims in the general population.

Aims: Victims of violence, accidents, theft, and serious threat (hereafter abbreviated as victims) are more than nonvictims at risk for problems in different domains, varying from mental health to legal problems. However, the extent to which victims with these problems compared to nonvictims with similar problems receive problem-related professional or formal help is unclear. It is unknown if predictors of unmet needs differ between victims and nonvictims.

Do initial mental health, somatic, and social problems predict postdisaster lack of social support in the medium term? A latent profile analysis.

Objective: Findings on the relationship between social support and mental health problems after potentially traumatic events vary across studies. Aim of our longitudinal study is to assess to what extent initial postdisaster mental health, somatic, and social functioning problems affect social support 1.5 years later.

The impact of the nutri-score on food choice: A choice experiment in a Dutch supermarket.

Front-of-package (FOP) nutrition labels are placed on products to help consumers make healthy food choices. A lab-in-field experiment was conducted to test the effectiveness of two FOP labels in promoting healthy food choices among Dutch consumers, and to examine whether dieters and health conscious shoppers are more likely to use the FOP labels. In addition, it was examined whether the placement of relatively "good" FOP label scores on products might inadvertently lead to increases in serving sizes.

Chronic mental health problems and use of mental health services among adults with and without adverse childhood experiences: a 6-year longitudinal population-based study.

Background: The negative effects of single and multiple adverse childhood experiences (ACE) on adult mental health are well-documented. However, little is known about the prevalence of chronic mental health problems (MHPs) and use of mental health services (MHSs) compared to adults without an ACE history.

Aims: Examine differences in the prevalence of chronic MHP and MHS use between adults without and with a single and multiple ACE history, and MHS use among ACE and no-ACE adults with chronic MHP.

Provision of social support by mayors in times of crisis: a cross-sectional study among Dutch mayors.

: During times of crisis, mayors may play an important role as public leaders and providers of social support to affected residents. However, empirical studies have not yet been conducted among the involved mayors about the support they provide and the factors associated with it. : The aim is to examine the support the mayors provided to the affected residents during crises and to test the possible determinants of this support.

Anxiety and depression symptoms, the recovery from symptoms, and loneliness before and after the COVID-19 outbreak among the general population: Findings from a Dutch population-based longitudinal study.

Objectives: Examine the effects of the COVID-19 pandemic on the mental health and loneliness in the general population. More specifically, the study focused on prevalence of anxiety and depression symptoms, the extent to which individuals with existing symptoms recovered or not, the prevalence of subtypes of loneliness, and the extent to which loneliness before and during this pandemic was associated with anxiety and depression symptoms.

Methods: Data was extracted from the longitudinal LISS panel, based on a probability sample of the Dutch population, with assessments on loneliness in October 2019 (T1) and June 2020 (T4), and anxiety and depression symptoms in November 2019 (T2), March 2020 (T3) and June 2020 (T4; Ntotal = 4,084).

Victims of medical errors and the problems they face: a prospective comparative study among the Dutch population.

Background: A large number of studies are devoted to medical errors, but only a few focused on the problem's victims of these errors face. Prospective comparative studies on this topic are absent. The aim of this prospective comparative study is to fill this gap of scientific knowledge that may help to improve the care for victims.

Sleep characteristics across the lifespan in 1.1 million people from the Netherlands, United Kingdom and United States: a systematic review and meta-analysis.

We aimed to obtain reliable reference charts for sleep duration, estimate the prevalence of sleep complaints across the lifespan and identify risk indicators of poor sleep. Studies were identified through systematic literature search in Embase, Medline and Web of Science (9 August 2019) and through personal contacts. Eligible studies had to be published between 2000 and 2017 with data on sleep assessed with questionnaires including ≥100 participants from the general population.

Anxiety and depression symptoms, and lack of emotional support among the general population before and during the COVID-19 pandemic. A prospective national study on prevalence and risk factors.

Background: The effects of the COVID-19 pandemic on the mental health and emotional support among the general population are unclear. We therefore assessed if the prevalence of high Anxiety and Depression Symptoms (ADS) levels and lack of Emotional Support (ES) increased, and if risk factors of ADS and ES changed.

Methods: Data was extracted from surveys conducted with the Dutch longitudinal population-based LISS panel (N = 3,983).

Does pre-event lack of emotional support increase the risk of post-event PTSD, anxiety, depression symptoms and lack of support? A comparative population-based study among victims of threat and violence.

Our knowledge about the effects of perceived emotional support on PTSD, anxiety and depressive symptoms after serious threat and violence is primarily based on post-event studies. Very little is known about the extent to which (1) victims lacking pre-event emotional support are more at risk of post-event symptoms and lack of post-event support than victims with pre-event emotional support, and (2) victims with pre-event emotional support and victims lacking emotional support are more at risk of post-event anxiety and depressive symptoms than nonvictims with similar pre-event support levels. For this purpose, we conducted a 2-wave prospective study (VICTIMS) using the Dutch population-based longitudinal LISS panel.

Pre-outbreak determinants of perceived risks of corona infection and preventive measures taken. A prospective population-based study.

Objectives: Assess how people perceive the risks of coronavirus infection, whether people take preventive measures, and which pre-outbreak factors contribute to the perceived risks and measures taken, such as pre-outbreak respiratory problems, heart problems, diabetes, anxiety and depression symptoms, loneliness, age, gender, marital and employment status and education level.

Methods: Data were collected in the longitudinal LISS panel, based on a random sample of the Dutch population. The coronavirus survey started on March 2, and the data collection ended on March 17 2020.
