Identifying the nature of episodic memory deficits in Major Depressive Disorder using a Real-World What-Where-When task.

ABSTRACTDeficits in episodic memory have been reported in various psychiatric conditions, including Major Depressive Disorder (MDD). Many widely used episodic memory tests do not have the ability to distinguish between impaired memory of separate components of a real-life event (e.g., what happened, where it happened and when), and impaired binding of such real-life features. To address this issue, a naturalistic, real-world What-Where-When memory task was employed to assess the nature of episodic memory impairments in MDD. A validation study established that the task is sensitive to age-related episodic memory changes, and that intentional encoding does not invalidate the task. The main study then compared the performance of patients with depression and control participants on the intentionally encoded WWW task. Patients with MDD presented an overall episodic memory impairment arising from deficits in object memory and the ability to bind objects to temporal context. Taken together, our study confirms the episodic memory impairment in MDD, by providing evidence of deficient object memory and reduced ability to bind temporal context to objects in patients. Our naturalistic WWW task presents a promising approach for thorough identification of the nature of episodic memory impairments, under a real-world environment, in various conditions, including MDD.

Recovery Barrier Characterizations by Hospitalized Patients with Substance Use Disorders: Results from a Randomized Clinical Study on Inpatient Peer Recovery Coaching.

Patients hospitalized with medical complications from substance use disorder (SUD) encounter unique health problems that may complicate their recovery. Recovery barriers are not well understood in this population. The study objective is to characterize recovery barriers in this patient population. Participants (n = 96) in this six-month longitudinal study were randomized to a peer recovery coaching intervention or standard of care. The primary outcome measures were qualitative, open-ended questions addressing factors interfering with participants' recovery. Data were analyzed using content analysis. Themes were identified a priori using past research on recovery capital domains; these seven barriers were (1) psychological health difficulties, (2) physical health challenges, (3) lack of social support, (4) insufficient treatment or recovery support to maintain sobriety, (5) environmental and housing concerns, (6) deficits in coping skills, and (7) lack of meaningful activities. At baseline, the most common recovery barriers were in the environment and housing (28.1%), psychological health (27.1%), and social support (22.9%) domains. At six-month follow-up, participants were asked to describe barriers they felt they had made improvement in over the last six months. The primary themes that participants reported improvements in were treatment and recovery support to maintain sobriety (52.1%), coping skills (35.4%), and social support (27.1%). Hospitalization and participation in a randomized controlled trial may be a turning point in which to address recovery barriers for patients hospitalized with complications from SUD.

COVID-19 and influenza vaccine uptake in women with criminal-legal system involvement.

OBJECTIVE: Given their vulnerable health status and resource constraints, the perspectives of women with criminal-legal involvement (WCLI) are important but not usually represented in the literature on vaccine interest and vaccine hesitancy. This study aims to examine how the COVID-19 pandemic and vaccine affected the influenza vaccine uptake among WCLI. METHODS: A cross-sectional secondary analysis was conducted using data collected from the Tri-City study, which followed WCLI in three U.S. cities from 2019 to 2023. We mapped the distribution of influenza vaccine uptake in 2019-2023 and developed a composite outcome that reflected participants' patterns of Y/N to influenza vaccine, which were categorized into four groups: Influenza Vaccine Supportive, Influenza Vaccine Adaptive, Influenza Vaccine Discontinued, and Influenza Vaccine Resistant. RESULTS: Out of 507 people: 23.7% were Supportive, 8.5% Adaptive, 15.2% Discontinued and 38.3% Resistant. People who received the COVID vaccine had significantly lower odds of being identified as Discontinued (OR = 0.42, 95%CI = 0.20-0.87, p = .020) and Resistant (OR = 0.23, 95%CI = 0.13-0.43, p < .001), compared to the Supportive group. Mistrust toward COVID-19-related information was a significant independent predictor of being Adaptive (OR = 1.59, 95%CI = 1.08-2.35, p = .019), Discontinued (OR = 1.61, 95%CI = 1.15-2.25, p = .006), and Resistant (OR = 1.54, 95%CI = 1.19-2.00, p < .001) relative to Supportive. CONCLUSIONS: Vaccine hesitancy poses significant challenges to public health efforts, with apparent dampening effect across vaccines. Public health messaging and clinical interactions informed by best practices in communication tailored to the lived experience of all people, including women with criminal-legal system involvement, will be necessary to inform future interventions aimed at increasing vaccine uptake.

A Real-world What-Where-When Memory Test.

Episodic memory is a complex memory system which allows recall and mental re-experience of previous episodes from one's own life. Real-life episodic memories are about events in their spatiotemporal context and are typically visuospatial, rather than verbal. Yet often, tests of episodic memory use verbal material to be recalled (word lists, stories). The Real-World What-Where-When memory test requires participants to hide a total of 16 different objects in 16 different locations over two temporal occasions, 2 h apart. Another two hours later, they are then asked to recall which objects (What) they had hidden in which locations (Where) and on which of the two occasions (When). In addition to counting the number of correctly recalled complete what-where-when combinations, this task can also be used to test real-world spatial memory and object memory. This task is sensitive to normal cognitive aging, and correlates well with performance on other episodic memory tasks, while at the same time providing more ecological validity and being cheap and easy to run.
