RESUMO

The COVID-19 pandemic and its lockdown in March 2020 have led to changes in lifestyle and increased levels of anxiety, depression, and fatigue. This survey examined a number of factors (anxiety state, sleep quality, daily activities, mental load, work-related variables) influencing mental and physical fatigue during lockdown and how these relations have evolved one year later. A cohort of 430 workers and 124 retirees were recruited in April-May 2020 (lockdown period, data set 1), and a subsample (133 workers and 40 retirees) completed the same questionnaire in April-May 2021 (data set 2). Linear regression models showed a significant subjective increase in both physical and mental fatigue in both worker and retiree groups during lockdown, and a supplementary increase in physical fatigue and anxiety level in spring 2021 compared to the lockdown period. During lockdown, anxiety level, concerns about COVID-19, work flexibility, mental load, and sleep metrics were associated with the evolution of fatigue among workers. For retirees, only anxiety and physical activity levels were linked to changes in physical fatigue. In April-May 2021, the only associations which remained significant were those in workers between fatigue and anxiety level and workload. These findings suggest that the increased fatigue levels during the lockdown are likely due to the swift and significant changes in daily routines (such as sleep patterns and work dynamics) and psychological states (including increased anxiety and concerns) prompted by the sanitary crisis. On the other hand, the increase in fatigue observed one year after the beginning of the pandemic seems to result from more psychological factors associated with the health situation.

RESUMO

OBJECTIVE: Evidence-based practice (EBP) is an approach that encourages clinicians to base their practice on evidence to improve the quality of patient care and reduce uncertainty in their clinical decisions. However, the state of knowledge and practice of neuropsychologists in French-speaking countries is still unknown. This study aimed to find out what these neuropsychologists know about EBP and whether they use it. METHOD: A questionnaire with 39 questions for French-speaking neuropsychologists was distributed. The questions focused on neuropsychologists' knowledge and use of EBP and information that guide their clinical decisions. RESULTS: A total of 392 respondents started the survey. The data show that only 35% correctly defined EBP and there was confusion between this practice and the strict use of research data. In practice, their decisions are influenced by multiple factors, including the patient's difficulties and advice from peers. Regarding the research, a significant proportion of the sample stated that they did not search the scientific literature frequently. Barriers to accessing scientific information and ineffective article-reading behavior were highlighted. CONCLUSION: A lack of knowledge of EBP among French-speaking neuropsychologists was observed. Furthermore, the factors influencing their decision-making do not clearly fit the definitions of EBP. Information-seeking behaviors show several weaknesses and barriers to the integration of scientific evidence into practice. These results are like those of other studies conducted among psychologists or in other health professions. We will discuss possible courses of action that could be implemented to improve the knowledge and use of EBP.

RESUMO

While aging has been associated with decreased retrieval of episodic memory details, subjective ratings about memory quality seem to remain stable. This suggests that subjective memory judgments are based on different information according to age. Here, we tested the hypothesis that older people would rather base their subjective judgments on the retrieval of personal elements (such as emotions and thoughts), whereas younger people would rather base their judgments on the retrieval of event-related elements (such as time, place, and perceptual details). Sixty participants (20 to 79 years old) performed eight actions in a virtual apartment and were then asked to verbally recall each action with a maximum of associated elements and to rate the subjective quality of their memories. The elements reported were classified into "person-related" and "event-related" categories. Executive functions, memory performance on traditional memory tasks, and subjects' perception of memory functioning were also evaluated. Results revealed that aging was associated with reduced retrieval of event-related elements, which was explained by decreasing executive resources. However, age did not affect the retrieval of person-related elements, and the subjective memory judgments of older people were not based on these elements to a greater extent than those of younger people. Finally, our results highlight the value of virtual reality (VR) in memory evaluations since subjects' perception of memory functioning was associated with their performance in the VR task but not in traditional memory tasks.

RESUMO

BACKGROUND: Cognitive difficulties are a frequent complaint in long COVID and persist for more than a year post- infection. There is a lack of evidence-based data on effective intervention strategies. Non-pharmacological intervention programs that are used with other neurological populations have not yet been the subject of controlled trials. COVCOG is a multicentric, randomized trial comparing cognitive intervention and a cognitive-behavioural counselling. METHODS/DESIGN: Patients with long covid are selected and recruited at least three months post-infection. Patients are randomised in a 1:1 ratio into the cognitive (neuropsychological psychoeducation) and affective (emotion management with cognitive-behavioural counselling) intervention arms. The inclusion of 130 patients is planned. The cognitive intervention includes psycho-educational modules on fatigue and sleep, attention and working memory, executive functions and long-term memory. The affective intervention includes modules on emotion recognition and communication, uncertainty management and behavioral activation. The main objective is to reduce cognitive complaints 2 months after the intervention. A Follow-up is also planned at 8 months. DISCUSSION: Given the long-term effects of Covid on cognition and the negative effects of cognitive impairment on quality of life and social participation, it is important to determine whether low-dose, non-pharmacological interventions can be effective. The trial will determine which of the usual types of intervention is the most effective. TRIAL REGISTRATION: Clinicaltrials.gov Number: NCT05167266 (21/12/ 2021).

RESUMO

ABSTRACTThis study aimed to validate a French version of the Autobiographical Recollection Test (ART), a 21-item self-report questionnaire developed by Berntsen, D., Hoyle, R. H., & Rubin, D. C. (2019; The Autobiographical Recollection Test (ART): A measure of individual differences in autobiographical memory. Journal of Applied Research in Memory and Cognition, 8(3), 305-318) examining the subjective quality people attribute to their autobiographical memories. It measures seven distinct but correlated dimensions of memories' quality varying between individuals: vividness, narrative coherence, reliving, rehearsal, visual imagery, scene, and life-story relevance. 373 participants aged from 18 to 87 years old were invited to complete the questionnaire by rating on a 7-point Likert scale the degree to which they agree with each item. Demographic data and information about their perception of their memory functioning and satisfaction were also collected. Confirmatory factor analysis confirmed the initial seven-factor structure of the ART. Moreover, results showed desirable psychometric properties, with good internal consistency (.94) and test-retest reliability (.83). This scale was also correlated with participants' perception of memory functioning in daily life. However, there was no correlation with age, confirming prior studies showing that the subjective quality of autobiographical memories does not decline with age. This study thus provides proof of the good psychometric properties of the French version of the ART and promotes its use to explore the subjective quality of autobiographical memories in clinical populations.

RESUMO

This randomized controlled trial explored the effects of parental reminiscing training on preschoolers' memory and metacognition among French-speaking White parents and their typically developing children (24 females, 20 males; Mmonths = 49.64) in Belgium. Participants were assigned, with age stratification, to the immediate intervention (n = 23) or waiting-list group (n = 21). The assessments were conducted by blind evaluators before the intervention, immediately after, and 6 months later. Resulting specifically from the intervention, parents sustainably improved their reminiscing style (e.g., greater provision of feedback and use of metamemory comments). The effects of the intervention on children's outcomes were, however, less clear. Based on the social-constructivist approach, such effects could be expected to occur later.

RESUMO

BACKGROUND: Given the importance of communication skills in the psychologist-patient relationship, several training programs have been proposed. Cumulative microtraining (CMT) has shown positive impacts on communication skills in previous studies. METHODS: The aim of this naturalistic pre-post study was to test the feasibility of a hybrid CMT program and obtain preliminary data on its impact on communication skills in French-speaking third-year psychology students. The training included an e-learning curriculum and role plays. Pre-post measures included recorded peer-to-peer role plays and self-assessments by participants themselves using the Calgary Cambridge Grid (n = 38) and assessed by an independent rater (n = 29) with a checklist focused on objective behaviors and the CARE questionnaire measuring perceived empathy. RESULTS: The results showed increases in most communication skills at different levels. Summarizing, paraphrasing, and structuring skills were significantly increased after training (all P ≤ 0.001), as were self-reported measurements (all P < 0.001), and empathy and confidence assessed by an independent rater (all p < 0.05). CONCLUSION: This study provides new evidence on the impact of CMT, including e-learning and role plays, on both self-rated assessments and assessments by an independent rater who measured communication and empathy in a population of French-speaking students. These findings highlight the importance of implementing such instruction in initial training despite the cost involved. It demonstrates the feasibility of its inclusion in university curriculum, facilitated by the adaptation of theoretical aspects of teaching in e-learning.

RESUMO

BACKGROUND: Stigmatization toward psychosis is persistent among mental health professionals (MHPs) and negatively impacts the patients' outcomes. One suggested way of reducing stigmatization is to expose MHPs to simulations of psychotic symptoms. This approach has been associated with an increase in empathy, but also with an increase in the desire of social distance. The addition of an empathic task (ET) has been suggested to neutralize this effect on social distance. The present study aims to (1) examine the effect of a remotely administered 360° immersive video (360IV) simulation on empathy and stigma among psychology students and (2) replicate the neutralizing effect of an ET on social distance. Finally, the potential role of immersive properties on changes will also be explored. METHODS: A 360IV simulating auditory hallucinations was constructed in collaboration with patient partners. 121 psychology students were allocated to one of three conditions: (i) exposure to the 360IV, (ii) exposure to the 360IV and to an ET (360IV + ET), and (iii) no exposure (control). Measures of empathy and stigma (stereotypes and social distance) were collected before and after the interventions. RESULTS: An increase of empathy was observed in the 360IV and 360IV + ET conditions compared to the control condition. There was an increase of stereotypes in all conditions and no effect on social distance. CONCLUSIONS: This study confirms the effectiveness of a 360IV simulation intervention in increasing empathy in psychology students but questions its efficacy in reducing stigma.

RESUMO

The influence of parental reminiscing style (the way parents discuss past events with their children) on the development of children's autobiographical memory has been well documented. The specific mechanisms involved in this effect, however, remain unknown. We explored the association between specific components of parental reminiscing and preschoolers' episodic memory. Fifty-three parent-child dyads (MChild Age = 53.13 months, 29 females) from Belgium were tested twice within a delay of about nine months. At the first time point, parental reminiscing style was assessed via a parent-child discussion of a prior standardised event (a museum visit) focusing on both the structure of parental interactions and the addressed content. At each time point, children were administered with story-recall tasks in the form of true-false recognition about previously heard stories. Generalised linear mixed-effect models were conducted on an item-by-item basis. Results indicated that parental reminiscing is associated with preschoolers' recognition memory performance at both time points, but not all reminiscing components equally influence children's performance. Specifically, parents' concretisations and metamemory talk were found to impact children's memory. The identification of these components provided insights for exploring the processes underlying the reminiscing-memory influence (in-depth encoding of information, binding processes, and metacognition).

RESUMO

Cancer can provoke fatigue, sleep disturbances, and emotional distress. Hypnosis interventions have shown positive short-term effects on these symptoms. However, less is known about their long-term effects. This study assessed the short- and long-term effects of a group intervention combining self-care and self-hypnosis on these symptoms in posttreatment cancer patients. Ninety-five female cancer survivors were randomized to either a hypnosis group intervention or wait-list control. Results showed significant decreases in fatigue, sleep difficulties and emotional distress after intervention for the hypnosis group intervention in comparison to the wait-list control. Most of these positive effects were maintained at 1-year follow-up. Most participants received the hypnosis group intervention approximately 10.65 months after diagnosis, and it is possible that delivering the intervention earlier after diagnosis could have achieved a more robust impact. Further studies are needed to replicate these results in comparison to an active control condition and investigate the best time postdiagnosis for initiating the intervention.

RESUMO

The present study examined the evolution observed in amnesic patients' use of motor fluency when making recognition memory decisions. In this experiment, 9 patients with amnesia and 18 matched controls were presented with two recognition memory tasks composed of 3 types of items: (1) natural words, (2) nonwords difficult to pronounce, and (3) nonwords easy to pronounce, the latter having been shown to be processed in a surprisingly fluent manner as long as participants can articulate them at a subvocal level (i.e., oral motor fluency). Our results provide evidence that the motor-movement manipulation was successful to induce a fluency effect. More specifically, data revealed that both amnesic patients and control participants showed a pattern of response consistent with the use of fluency as a cue to memory for studied items. However, only control participants relied on fluency to increase their rate of "yes" responses for unstudied items. These results suggest that patients with amnesia set a more conservative response criterion before relying on oral motor fluency, showing a pattern consistent with the idea that fluency is only used as a cue to memory when it exceeds a certain threshold. These findings are discussed in terms of adaptative metacognition strategies implemented by amnesic patients to reduce fluency-based memory errors as well as in terms of the variations that seem to occur in these strategies depending on the type of fluency that is experienced.

RESUMO

Emotional distress, communication, and dyadic coping difficulties are common among cancer patients and their partners. Hypnosis-based interventions can improve emotional distress in patients. We designed a group intervention combining self-hypnosis and self-care techniques. We hypothesized an effect of the intervention on emotional distress, conjugal communication, and dyadic coping, considered in patients and their partners. Our exploratory controlled study included 55 women with cancer and 55 partners. Participants completed questionnaires before and after the intervention, which was delivered to patients only. No significant effect of the intervention was revealed for patients or partners. Positive correlations between patients' and partners' communication and dyadic coping were revealed. However, to address couples' or partners' difficulties, interventions specifically designed for couples or partners must be tested.

RESUMO

While occasional déjà vu is benign in the general population, rare neuropsychological cases with persistent déjà vu have been described in the literature. We report the case of MN, a 25-year-old woman, who suffered a cerebral haemorrhage in the right thalamo-callosal region and experienced recurrent déjà vu episodes. Through clinical interviews and memory tasks related to déjà vu, we assumed that source memory errors and an inappropriate feeling of familiarity (measured by the number of false recognitions) were critically involved in MN's déjà vu. Based on this, we developed the first neuropsychological intervention dedicated to déjà vu. The rationale was to train MN to detect elements that could produce an inappropriate feeling of familiarity and to promote metacognitive awareness about déjà vu. This intervention was effective at reducing the frequency of déjà vu episodes in MN's daily life, as well as the number of false recognitions in memory tasks. In addition to its clinical contribution, this single-case study contributes to the limited literature on patients whose déjà vu is not related to epileptic abnormalities and medial temporal brain damage, and provide supportive evidence of the role of an erroneous feeling of familiarity and of metacognitive processes in déjà vu.

RESUMO

We tested whether changes in attribution processes could account for the developmental differences observed in how children's use fluency to guide their memory decisions. Children ranging in age from 4 to 9 years studied a list of familiar or unfamiliar cartoon characters. In Experiment 1 (n = 84), participants completed a recognition test during which the perceptual fluency of some items was enhanced using a prime. In Experiment 2 (n = 96), participants completed a source recollection judgment on their recognition decisions. Primed items were recognized at a higher rate than unprimed items. However, while young children rely on fluency for all items, older children use fluency only for unfamiliar items. This pattern came together with a reduction in familiarity-based-but not recollection-based-memory responses.

RESUMO

OBJECTIVE: Recent studies in Alzheimer's disease (AD) have suggested that AD patients are not always able to rely on their feeling of familiarity to improve their memory decisions to the same extent as healthy participants. This underuse of familiarity in AD could result from a learned reinterpretation of fluency as a poor cue for memory that would prevent them to attribute a feeling of fluency to a previous encounter. The primary goal of this study was to determine whether AD patients could relearn the association between processing fluency and past exposure after being repeatedly exposed to situations where using this association improves the accuracy of their memory decisions. METHOD: Thirty-nine patients with probable AD were recruited and asked to complete several recognition tests. During these tests, participants were put either in a condition where the positive contingency between fluent processing and previous encounters with an item was systematically confirmed (intervention condition) or in a condition where there was no correlation between fluency and prior exposure (control condition). The efficacy of the intervention was evaluated at three time points (baseline, posttest, and 3-month follow-up). RESULTS: Our results indicated that all AD patients do not benefit to the same extent from the training. Two variables appeared to influence the likelihood that participants increase and maintain their reliance on the fluency cues after the intervention: the ability to detect the fluency manipulation and the preservation of implicit metacognitive skills. CONCLUSION: These findings indicate the importance of metacognition for inferential attribution processes in memory.

RESUMO

OBJECTIVE: Cancer has a lot of consequences such as fatigue, sleep disturbances, emotional distress, cognitive impairment and reduced physical activity. Some hypnosis-based psychological interventions showed positive effects on fatigue, sleep and emotional distress, but generally focused on breast cancer patients. Our study aimed at assessing the effects of a group intervention combining self-care and self-hypnosis on quality of life of cancer patients. METHODS: Our longitudinal randomized-controlled trial assessed the benefits of the intervention first on fatigue and secondly on associated symptoms (sleep, emotional distress, cognitive impairment and reduced physical activity) of post-treatment cancer patients, and investigated predictors of the evolution of fatigue. All variables were measured with questionnaires and an actigraph (for sleep and physical activity). RESULTS: Ninety five women with different cancers were included in our study. Group-by-time effects were showed for fatigue, sleep, emotional distress and cognitive functioning: symptoms have improved in the intervention group compared to wait-list control group. Three predictors of the evolution of fatigue were revealed: depression, anxiety and worry. CONCLUSIONS: Our group intervention had benefits for post-treatment cancer patients' quality of life. Impacting emotional distress could be important in order to decrease fatigue. Further studies are needed to replicate our results. This intervention could be easily implemented to improve quality of life of cancer patients. Registration: ClinicalTrials.gov (NCT03144154). Retrospectively registered on the 1st of May, 2017.

RESUMO

The integrative memory model formalizes a new conceptualization of memory in which interactions between representations and cognitive operations within large-scale cerebral networks generate subjective memory feelings. Such interactions allow to explain the complexity of memory expressions, such as the existence of multiples sources for familiarity and recollection feelings and the fact that expectations determine how one recognizes previously encountered information.

RESUMO

OBJECTIVE: The primary aim of this study was to test whether differences in the ability of amnesic and healthy participants to detect alternative sources of fluency can account for differences observed in the use of fluency as a cue for memory. METHOD: Patients with severe memory deficits and matched controls were presented with 3 forced-choice recognition tests. In each test, an external source of fluency was provided by manipulating the perceptual quality of the studied items during the test phase. The detectability of the perceptual manipulation varied in each test (i.e., a 10%, 20%, or 30% contrast reductions were given). RESULTS: The results indicated that all participants were able to rely on fluency when making recognition decisions as long as the perceptual manipulation remained unnoticed. It is interesting that our data also revealed that the level of contrast reduction at which the alternative source is detected differs between healthy controls and amnesic patients. Specifically, patients with amnesia appeared to disqualify fluency as a cue for memory even when the contrast reduction was moderate, whereas healthy participants disqualified fluency only when the contrast reduction was clearly visible. CONCLUSION: Overall, our results seem to suggest that the ability to use fluency is probably not impaired in amnesia but undergoes metacognitive changes resulting in the implementation of explicit or implicit strategies aiming at tracking alternative sources in order to reduce memory errors.

RESUMO

OBJECTIVE: The primary aim of this study was to test whether differences in the ability of patients with Alzheimer's disease (AD) and healthy participants to detect alternative sources of fluency can account for differences observed in the use of fluency-that is, the ease with which information is processed-as a cue for memory. METHOD: Twenty-two patients with AD and 22 matched controls were presented with three forced-choice visual recognition tests. In each test, an external source of fluency was provided by manipulating the perceptual quality of the items during the test phase. The detectability of the perceptual manipulation varied in each test (i.e., 10%, 20%, or 30% contrast reduction were given). RESULTS: Data indicated that AD patients rely on fluency in a similar extent than older adults as long as they demonstrate intact detection of differences in the perceptual quality of the items. Specifically, it appears that patients' ability to visually discriminate stimuli differing in terms of their perceptual quality is critical for patients to be able to implement strategies to appropriately use or correctly disqualify fluency during a recognition task. CONCLUSION: Overall, these findings suggest that the disruption of some basic cognitive processes could prevent AD patients to experience fluency in a similar extent than healthy controls. However, when the ability to detect differences in the perceptual quality of the stimuli was taken into account, patients appeared to be as able as controls to rely on fluency to guide their memory decisions.
