- Changes in cannabis consumption during the global COVID-19 lockdown: The International COVISTRESS StudyPublication . Salles, Juliette; Yrondi, Antoine; Marhar, Fouad; Andant, Nicolas; Dorlhiac, Raimundo Avilés; Binh, Quach; Jiao, Jiao; Antunes, Samuel; Ugbolue, Ukadike Chris; Guegan, Julien; Karine, Rouffiac; Pereira, BrunoIntroduction: COVID-19 lockdown measures have been sources of both potential stress and possible psychological and addiction complications. A lack of activity and isolation during lockdown are among the factors thought to be behind the growth in the use of psychoactive substances and worsening addictive behaviors. Previous studies on the pandemic have attested to an increase in alcohol consumption during lockdowns. Likewise, data suggest there has also been a rise in the use of cannabis, although it is unclear how this is affected by external factors. Our study used quantitative data collected from an international population to evaluate changes in cannabis consumption during the lockdown period between March and October, 2020. We also compared users and non-users of the drug in relation to: (1) socio-demographic differences, (2) emotional experiences, and (3) the information available and the degree of approval of lockdown measures.Methods: An online self-report questionnaire concerning the lockdown was widely disseminated around the globe. Data was collected on sociodemographics and how the rules imposed had influenced the use of cannabis and concerns about health, the economic impact of the measures and the approach taken by government(s).Results: One hundred eighty two respondents consumed cannabis before the lockdown vs. 199 thereafter. The mean cannabis consumption fell from 13 joints per week pre-lockdown to 9.75 after it (p < 0.001). Forty-nine respondents stopped using cannabis at all and 66 admitted to starting to do so. The cannabis users were: less satisfied with government measures; less worried about their health; more concerned about the impact of COVID-19 on the economy and their career; and more frightened of becoming infected in public areas. The risk factors for cannabis use were: age (OR = 0.96); concern for physical health (OR = 0.98); tobacco (OR = 1.1) and alcohol consumption during lockdown (OR = 1.1); the pre-lockdown anger level (OR = 1.01); and feelings of boredom during the restrictions (OR = 1.1).Conclusion: In a specific sub-population, the COVID-19 lockdown brought about either an end to the consumption of cannabis or new use of the drug. The main risk factors for cannabis use were: a lower age, co-addictions and high levels of emotions.
- Perceived discrimination based on the symptoms of covid-19, mental health, and emotional responses–the international online COVISTRESS surveyPublication . DAMBRUN, Michael; Bonetto, Eric; MOTAK, Ladislav; Baker, Julien S.; Bagheri, Reza; Saadaoui, Foued; Rabbouch, Hana; Zak, Marek; Nasir, Hijrah; Mermillod, Martial; Gao, Yang; Antunes, Samuel; Ugbolue, Ukadike Chris; Pereira, Bruno; Bouillon-Minois, Jean-Baptiste; Nugier, Armelle; Clinchamps, Maëlys; Dutheil, FrédéricBackground Despite the potential detrimental consequences for individuals’ health and discrimination from covid-19 symptoms, the outcomes have received little attention. This study examines the relationships between having personally experienced discrimination based on the symptoms of covid-19 (during the first wave of the pandemic), mental health, and emotional responses (anger and sadness). It was predicted that covid-19 discrimination would be positively related to poor mental health and that this relationship would be mediated by the emotions of anger and sadness. Methods The study was conducted using an online questionnaire from January to June 2020 (the Covistress network; including 44 countries). Participants were extracted from the COVISTRESS database (Ntotal = 280) with about a half declaring having been discriminated due to covid-19 symptoms (N = 135). Discriminated participants were compared to non-discriminated participants using ANOVA. A mediation analysis was conducted to examine the indirect effect of emotional responses and the relationships between perceived discrimination and self-reported mental health. Results The results indicated that individuals who experienced discrimination based on the symptoms of covid-19 had poorer mental health and experienced more anger and sadness. The relationship between covid-19 personal discrimination and mental health disappeared when the emotions of anger and sadness were statistically controlled for. The indirect effects for both anger and sadness were statistically significant. Discussion This study suggests that the covid-19 pandemic may have generated discriminatory behaviors toward those suspected of having symptoms and that this is related to poorer mental health via anger and sadness.
- The major worldwide stress of healthcare professionals during the first wave of the COVID-19 pandemic – the international COVISTRESS surveyPublication . Couarraze, Sébastien; Delamarre, Louis; Marhar, Fouad; Quach, Binh; Jiao, Jiao; Avilés, Raimundo; Saadaoui, Foued; Liu, Andy Su-I; Dubuis, Benoït; Antunes, Samuel; Andant, Nicolas; Pereira, Bruno; Ugbolue, Samuel C; Baker, Julien S.; Clinchamps, Maëlys; Dutheil, FrédéricThe COVID-19 pandemic has initiated an upheaval in society and has been the cause of considerable stress during this period. Healthcare professionals have been on the front line during this health crisis, particularly paramedical staff. The aim of this study was to assess the high level of stress of healthcare workers during the first wave of the pandemic.
- The Portuguese Third Version of the Copenhagen Psychosocial Questionnaire: Preliminary Validation Studies of the Middle Version among Municipal and Healthcare WorkersPublication . Cotrim, Teresa P.; Bem-Haja, Pedro; Pereira, Anabela; Fernandes, Cláudia; Azevedo, Rui; Antunes, Samuel; Pinto, Joaquim S.; Kanazawa, Flávio; Souto, Isabel; Brito, Elisabeth; Silva, Carlos FernandesA third version of the Copenhagen Psychosocial Questionnaire (COPSOQ III) was developed internationally aiming to respond to new trends in working conditions, theoretical concepts, and international experience. This article aims to present the preliminary validation studies for the Portuguese middle version of COPSOQ III. This is an exploratory cross-sectional study viewing the cross-cultural adaption of COPSOQ III to Portugal, ensuring the contents and face validity and performing field-testing in order to reduce the number of items and to obtain insight into the data structure, through classic test theory and item response theory approaches. The qualitative study encompassed 29 participants and the quantitative one 659 participants from municipalities and healthcare settings. Content analysis suggested that minor re-wording could improve the face validity of items, while a reduced version, with 85 items, shows psychometric stability, achieving good internal consistency in all subscales. The COPSOQ III Portuguese middle version proved to be a valid preliminary version for future validation studies with various populations, able to be used in correlational studies with other dimensions.
