A narrative systematic review of changes in mental health symptoms from before to during the COVID-19 pandemic.

The onset of the COVID-19 pandemic raised concerns regarding population-wide impacts on mental health. Existing work on the psychological impacts of disaster has identified the potential for multiple response trajectories, with resilience as likely as the development of chronic psychopathology. Early reviews of mental health during the pandemic suggested elevated prevalence rates of multiple forms of psychopathology, but were limited by largely cross-sectional approaches. We conducted a systematic review of studies that prospectively assessed pre- to peri-pandemic changes in symptoms of psychopathology to investigate potential mental health changes associated with the onset of the pandemic (PROSPERO #CRD42021255042). A total of 97 studies were included, covering symptom clusters including obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), fear, anxiety, depression, and general distress. Changes in psychopathology symptoms varied by symptom dimension and sample characteristics. OCD, anxiety, depression, and general distress symptoms tended to increase from pre- to peri-pandemic. An increase in fear was limited to medically vulnerable participants, and findings for PTSD were mixed. Pre-existing mental health diagnoses unexpectedly were not associated with symptom exacerbation, except in the case of OCD. Young people generally showed the most marked symptom increases, although this pattern was reversed in some samples. Women in middle adulthood in particular demonstrated a considerable increase in anxiety and depression. We conclude that mental health responding during the pandemic varied as a function of both symptom cluster and sample characteristics. Variability in responding should therefore be a key consideration guiding future research and intervention.

Course and clinical correlates of obsessive-compulsive disorder with or without comorbid personality disorder.

BACKGROUND: Personality disorders (PDs) are often comorbid with obsessive-compulsive disorder (OCD) which may influence symptom presentation and course. This investigation sought to examine the impact of comorbid PDs on clinical presentation and symptom chronicity in a large, prospective longitudinal OCD study. METHODS: Participants (n = 263) were treatment-seeking adults with a primary diagnosis of OCD separated into two groups: individuals with and without a co-occurring PD. We conducted two-tailed t-tests to compare symptom severity, functioning, and quality of life between the OCD + PD group (n = 117) and the OCD w/o PD group (n = 146). Chronicity analyses were conducted to compare the amount of time in-episode for OCD and major depressive disorder (MDD) between the two groups. RESULTS: The OCD + PD group reported greater OCD and depression severity, lower levels of psychosocial functioning and worse quality of life than the OCD w/o PD group. The OCD + PD group exhibited greater OCD and MDD symptom chronicity; over 5 years the OCD + PD group spent 16.2 % weeks longer at full criteria for OCD and three times as many weeks in episode for MDD than the OCD w/o PD group. LIMITATIONS: Focusing on PDs as a group limited our ability to make observations about specific PDs. Further, the participants in our sample were predominantly White and all were treatment seeking which limits the generalizability of our findings. CONCLUSIONS: Our results suggest that those with OCD and comorbid PDs present with greater overall impairment and may require additional considerations during treatment conceptualization and planning.

Personality traits as predictors of OCD remission: A longitudinal study.

BACKGROUND: Personality traits may confer vulnerability to psychopathology. However, few studies have examined the association between personality traits and obsessive-compulsive disorder (OCD) course. The present study investigates personality traits, OCD symptom severity, and illness duration as a predictor of OCD remission. METHODS: 166 treatment-seeking adults with OCD, recruited as part of the Brown Longitudinal Obsessive-Compulsive Study, completed the NEO Five-Factor Inventory 3 (NEO-FFI) and were in episode for OCD at time of NEO-FFI completion. Participants were followed for up to 3 years. RESULTS: Results suggest individuals with OCD had a 21 % likelihood of reaching remission over the course of 3 years. Greater OCD symptom severity and longer illness duration were associated with a decreased likelihood of remission. Among the five factors of personality, only low extraversion was associated with a decreased rate of remission. Neuroticism, openness, agreeableness, and conscientiousness were not associated with remission. LIMITATIONS: As this was an observational study, treatment was not controlled precluding examination of treatment on course. Further, data collected on age of onset and symptom severity during follow up were retrospective and therefore are also subject to recall bias. CONCLUSIONS: Our findings provide preliminary support that personality traits are potential factors impacting course and symptom presentation. Future research is necessary to determine the mechanisms in which personality traits may influence the presentation and course of OCD.
