Influência do uso de psicoativos na autopercepção da memória: análise durante a pandemia de SARS-CoV-2

O presente estudo teve como objetivo verificar a influência do uso de psicoativos na autopercepção da memória retrospectiva e prospectiva durante a pandemia de SARS-CoV-2. Trata-se de um estudo transversal, observacional e analítico conduzido em 2020 com a população brasileira. A pesquisa foi realizada por meio do preenchimento de questionários digitais contendo perguntas referentes a dados sociodemográficos, conhecimentos relacionados à pandemia, uso e frequência de substâncias psicoativas e o protocolo Prospective and Retrospective Memory Questionnaire (PRMQ-10). Os resultados foram analisados por estatística descritiva e pela regressão linear múltipla, com um nível de significância de 5%. Participaram 361 pessoas, sendo a maioria do gênero feminino, com ensino superior completo, que não pertenciam ao grupo de risco para a COVID-19 e que residiam com pessoas deste grupo. Quanto à frequência do uso de substâncias psicoativas, a maioria da amostra fez uso durante a pandemia de SARS-CoV-2 de forma esporádica. A frequência de uso de remédios com e sem prescrição foi capaz de prever a pontuação total do PRMQ-10, evidenciando que o uso de substâncias psicoativas utilizados interferiram na autopercepção da memória retrospectiva e prospectiva.

Caregiving during the Covid-19 pandemic: Factors associated with caregiver stress and cognition

Caregivers are critical in helping persons with dementia (PWD) live at home longer, but the caregiving experience is associated with increased risk of physical (Vitaliano et al., 2003; Son et al., 2007; Fonareva & Oken, 2014) and cognitive decline among caregivers (Pertle et al., 2015; Lathan et al., 2016; Vitaliano et al., 2017). The present study examined the caregiver experience during the time of the Covid-19 pandemic including factors associated with caregiver stress, burden, and self-reported cognition (i.e., prospective and retrospective memory errors). In a sample of 56 caregivers of PWD, caregiver stress was positively associated with reports of greater life change resulting from Covid-19 and a greater frequency of care recipient depressive and disruptive behaviors; however, caregiver stress was not associated with care recipient memory problems. Additionally, caregiver burden was negatively associated with ratings of preparedness for the pandemic, but not with availability of support services or the amount of time spent caregiving. Further, frequencies of prospective and retrospective memory mistakes were positively associated with perceived stress, but not with caregiver burden. These findings reveal that caregivers of PWD report greater experiences of stress associated with the Covid-19 pandemic and other facets of their caregiving responsibilities (e.g., care recipient depressive and disruptive behaviors, frequency of memory mistakes). This work is a first step in identifying areas in which caregivers need assistance and expanding the literature on caregiver cognition by measuring self-reported everyday memory performance.

The Independent and Joint Effects of Different Childhood Abuse Types on Subjective Prospective and Retrospective Memory Impairment During Pregnancy

Background and Objective: Childhood abuse is considered a risk factor in various health outcomes during pregnancy. However, no study has explored the relationship between childhood abuse and memory impairment during pregnancy. This study is the first to explore the relationship between childhood abuse and subjective memory impairment.Participants, Setting, and Methods: A total of 1,825 pregnant women were recruited from a comprehensive hospital in Shandong province, China, and completed a questionnaire survey. Multivariable linear regression analysis was used to explore the relationship between childhood abuse and subjective prospective and retrospective memory.Results: Pregnant women with high total childhood abuse scores had high prospective and retrospective memory impairment. Among pregnant women reporting only emotional abuse, only physical abuse, or only sexual abuse, women reporting only emotional abuse were found to have high prospective and retrospective memory impairment. Women with all three childhood abuse types also had high prospective and retrospective memory impairment.Conclusion: Women who experienced childhood abuse, especially childhood emotional abuse, had high subjective memory impairment during pregnancy. It is important to ask pregnant women about their experiences of childhood abuse, especially emotional abuse, during early prenatal care, as such abuse is likely to have negative effects on memory during pregnancy.

Individual Differences in Memory and Attention Processes in Prospective Remembering

Successful prospective memory (PM) involves not only detecting that an environmental cue requires action (i.e., prospective component), but also retrieval of what is supposed to be done at the appropriate moment (i.e., retrospective component). The current study examined the role of attention and memory during PM tasks that placed distinct demands on detection and retrieval processes. Using a large-scale individual differences design, participants completed three PM tasks that placed high demands on detection (but low demands on retrieval) and three tasks that placed high demands on retrieval (but low demands on detection). Additionally, participants completed three attention control, retrospective memory, and working memory tasks. Latent variable structural equation modeling showed that the prospective and retrospective components of PM were jointly influenced by multiple cognitive abilities. Critically, attention and retrospective memory fully mediated the relation between working memory and prospective memory. Furthermore, only attention uniquely predicted PM detection, whereas only retrospective memory uniquely predicted PM retrieval. These findings highlight the value of independently assessing different PM components and suggest that both attention and memory abilities must be considered to fully understand the dynamic processes underlying prospective remembering.

A Standardized Prospective Memory Evaluation of the Effects of COVID-19 Confinement on Young Students

The restriction imposed worldwide for limiting the spread of coronavirus disease 2019 (COVID-19) globally impacted our lives, decreasing people’s wellbeing, causing increased anxiety, depression, and stress and affecting cognitive functions, such as memory. Recent studies reported decreased working memory (WM) and prospective memory (PM), which are pivotal for the ability to plan and perform future activities. Although the number of studies documenting the COVID-19 effects has recently blossomed, most of them employed self-reported questionnaires as the assessment method. The main aim of our study was to use standardized tests to evaluate WM and PM in a population of young students. A sample of 150 female psychology students was recruited online for the administration of two self-reported questionnaires that investigated psychological wellbeing (DASS-21), prospective, and retrospective memory (PRMQ). Subjects were also administered two standardized tests for WM (PASAT) and PM (MIST). We found increased anxiety, depression, and stress and decreased PM as measured by self-reports. The perceived memory failures agreed with the results from the standardized tests, which demonstrated a decrease in both WM and PM. Thus, COVID-19 restriction has strongly impacted on students’ mental health and memory abilities, leaving an urgent need for psychological and cognitive recovery plans.
