An investigation of COVID-19 related worry in a United States population sample.

BACKGROUND: Although general anxiety has increased markedly since the onset of the COVID-19 pandemic, little has been reported about the demographic distribution of COVID-19 related worry, its relationship with psychological features, and its association with depression symptoms in the United States (US). METHODS: 2117 participants, selected to represent the age, gender, and race/ethnic distributions of the US population, completed an online survey. Analysis of variance and correlation analyses were used to assess relationships between the COVID-19 related worry score and demographic characteristics, past psychiatric diagnoses, personality dimensions, and current psychological symptoms. Logistic regression was used to evaluate the association between the COVID-19 worry score and depression symptoms. RESULTS: The COVID-19 worry score was markedly higher in younger (18-49 year-olds) than older participants, and moderately higher in men, those who were married or cohabiting, with post-college education, and/or living in large urban areas. The COVID-19 worry score also was markedly higher in those who reported having been diagnosed with a psychiatric disorder. The COVID-19 worry score correlated with neuroticism, current psychological symptoms, and COVID-19 risk and COVID-19 behavior scores. The COVID-19 worry score was associated with current depression symptoms (OR = 1.10, 95% CI = 1.09-1.11; p < 0.001) in univariable models and remained significant after adjustment for other correlates of depression, including COVID-19 risk. CONCLUSIONS: In this US sample, the COVID-19 worry score was inversely related to age, strongly related to psychological symptoms, and independently associated with depression symptoms. These findings have implications for the community mental health response to the COVID-19 pandemic in the US.

Contamination-related behaviors, obsessions, and compulsions during the COVID-19 pandemic in a United States population sample.

BACKGROUND: Contamination-prevention behaviors such as mask wearing and physical distancing are crucial to reduce coronavirus transmission during the COVID-19 pandemic. We hypothesized that engagement in these behaviors could provoke obsessions and phobias in vulnerable individuals in the community. METHODS: A total of 2117 participants, systematically selected to represent the age, gender, and race distributions of the US population, completed an online survey that assessed demographic characteristics, clinical features, COVID-19 risks, and COVID-19 contamination-prevention behaviors. Logistic regression was used to estimate the magnitude of the relationships between the COVID-19 behavior score and clinically significant contamination obsessions, contamination compulsions, and pre-COVID-19 to current change in obsessive-compulsive symptom scores. RESULTS: The COVID-19 behavior score was significantly associated with contamination obsessions (odds ratio (OR) = 1.15, 95% CI = 1.12-1.16; p < 0.001) and contamination phobias (OR = 1.14, 95% CI = 1.12-1.16; p < 0.001). The COVID-19 behavior score also was associated with pre-pandemic to current increase in the overall obsessive-compulsive symptom score (OR = 1.16, 95% CI = 1.09-1.23; p < 0.001), as well as increase in obsessive-compulsive symptom score excluding washing items (OR = 1.13, 95% CI = 1.07-1.19; p < 0.001). The magnitude of these relationships did not appreciably change, after adjustment for other variables associated with the outcomes. Moreover, the relationship was significant in those with or without OCD, and in individuals with different levels of doubt and COVID-19 risk. CONCLUSIONS: Contamination safety measures are critical for reducing the spread of COVID-19 in the community. However, they may be related to the development of contamination-related symptoms and OCD in vulnerable individuals, complicating the diagnosis and treatment of mental disorders during this period.
