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.

Directionality of change in obsessive compulsive disorder and depression over six years of prospective follow-up.

Major Depressive Disorder (MDD) is often comorbid with obsessive-compulsive disorder (OCD) yet little is known about the directionality of the association between OCD and depression symptoms. We aim to investigate the effect OCD symptoms has on depression symptoms and vice versa over an extended period of time. This is one of the first longitudinal studies to evaluate the relationship between OCD and depression in a large clinical sample. Participants (n = 324) were treatment-seeking adults with a primary diagnosis of OCD. OCD and depression symptoms were assessed annually over the six-year follow-up period. Random intercepts cross-lagged panel models (RI-CLPM) were conducted to compare unidirectional and bidirectional models over time. The best-fitting and most parsimonious model included paths with OCD symptoms predicting depression symptoms, but not vice versa. OCD symptom severity in a given year predicted next year depression severity. However, depression severity did not predict next-year OCD symptom severity in this sample. Our results suggest that depression severity may be secondary to OCD symptoms and treating OCD should be prioritized over treating depression.

Characteristics Associated With Loneliness and Coping Skills Utilization During the COVID-19 Pandemic.

Although stay-at-home orders and physical distancing measures are vital to managing the COVID-19 outbreak, there is concern these limitations on in-person contact may increase feelings of loneliness. The present study examined loneliness in relation to living situation, psychiatric symptoms, and coping skills utilization during the COVID-19 pandemic. The aim was to identify demographic and psychological factors that may contribute to greater feelings of loneliness. A sample of 125 adults (18 years and older) completed measures on loneliness, psychiatric symptoms, and coping skills in September 2020. Multiple regression analysis indicated living situation moderates the relationship between hours spent having remote conversations and loneliness. Remote conversation hours were associated with decreased loneliness in those living alone but was not associated with loneliness in those living with others. Multivariate regression analysis indicated that substance use and self-blame were associated with increased loneliness whereas the use of emotional support to cope with pandemic-related stress was associated with decreased loneliness. The current study highlights the importance of finding alternative ways to remain socially connected, particularly for those living alone. Increasing access to videoconferencing technology and promoting help-seeking behaviors may be a promising approach to manage loneliness during times of increased social isolation.

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.

Exposure and Response Prevention in the Treatment of Obsessive-Compulsive Disorder: Current Perspectives.

Numerous clinical trials support the efficacy of exposure and response prevention (ERP) for the treatment of obsessive-compulsive disorder (OCD). Accordingly, ERP has been formally recognized as a first-line, evidence-based treatment for OCD. This review discusses the theoretical underpinnings of the treatment from a behavioral and neurobiological perspective and summarizes the evidence supporting the efficacy of ERP across child and adult populations. Next, we discuss predictors of ERP treatment outcome and discuss implementation strategies designed to improve feasibility and adoption. Finally, strategies to improve treatment dissemination are discussed.

Investigating age-related changes in taste and affects on sensory perceptions of oral nutritional supplements.

BACKGROUND: sip feeds are oral nutritional supplements (ONSs) that are commonly prescribed to malnourished patients to improve their nutritional and clinical status. However, ONSs are poorly consumed and frequently wasted, with sweetness being identified as one of the factors leading to patients' dislike of ONSs. OBJECTIVES: to investigate if age affects sweetness thresholds and if this impacts upon perceived sweetness intensity, hedonic (sweetness and overall) and ranked preference of ONS products. DESIGN: prospective, observational. SUBJECTS: thirty-six young adults (18-33 years) and 48 healthy older adults (63-85 years). SETTING: Department of Food and Nutritional Sciences and the Clinical Health Sciences at the University of Reading. METHODS: detection and recognition threshold levels, basic taste identification and 'just about right' level of sweetness were examined. Three ONSs (chocolate, vanilla, strawberry) and sucrose solutions were evaluated for hedonic sweetness, overall hedonic liking, sweetness intensity and rank preference. RESULTS: significant differences were found in both sweetness detection and recognition thresholds (P = 0.0001) between young and older adults, with older adults more likely to incorrectly identify the taste (P = 0.0001). Despite the deterioration in sweetness sensitivity among the older adults, there were no significant differences found in sweetness intensity perceived for the ONS products presented (P > 0.05) when compared with the young adults. However, across both groups sweetness intensity was found to be correlated with overall product dislike across all flavour variants tested (R = 0.398, P = 0.0001). CONCLUSIONS: sweetness appears to be one of many factors contributing to the dislike of ONSs. Manufacturers are encouraged to reconsider the formulations of these products so that beneficial effects of ONSs can be delivered in a more palatable and acceptable form and wastage reduced.

Self-perceived musculoskeletal complaints: relationship to time use in women homemakers in Hong Kong.

OBJECTIVE: To examine patterns of time use and self-perceived musculoskeletal symptoms for women homemakers in Hong Kong using a cross-sectional survey. METHODS: A total of 216 women were selected from a women's center and a selected district by trained volunteers for a single interview using convenience sampling; 63 respondents had paid work and 153 were full-time homemakers. The study included a surveillance of self-reported musculoskeletal symptoms for the past 12 months and a time use log to report respondents' daily activities retrospectively during a 24-h reference day. RESULTS: Significant differences were found in the mean hours spent in paid work, outdoor activities, and passive leisure between respondents with paid and those with unpaid work (P = 0.000-0.021). Although the reported musculoskeletal problems were mostly mild to moderate, more than 60% of homemakers experienced at least one musculoskeletal symptom over the spine or upper or lower extremities in the 12 months prior to the survey. Homemakers were more likely to report discomfort in their upper back (OR = 2.70, 95% CI 1.27-5.71) and shoulder (OR = 3.50, 95% CI 1.21-10.19) while shopping; in their lower back (OR = 1.90, 95% CI 1.03-3.50), wrist (OR = 2.02, 95% CI 1.06-3.84), and hip (OR = 2.35, 95% CI 1.07-5.13) while washing utensils; and in their finger (OR = 1.45, 95% CI 1.03-2.03) and knee (OR = 1.84, 95% CI 1.19-2.82) during cleaning tasks. CONCLUSION: The results showed a high degree of musculoskeletal discomfort among women homemakers in Hong Kong. Modifying current participation in household chores like cleaning, washing utensils, and shopping is needed to reduce the risk of developing musculoskeletal problems in this population.
