RESUMO

Objective: Medical students' health and resilience have increasingly been the subject of current research in recent years. A variety of interventions are recommended to strengthen resilience or its known or suspected influencing factors, although the literature shows that the evidence on the effectiveness of the interventions is inconsistent. The present study investigated whether gratitude is a direct protective factor for resilience in medical students or whether resilience factors (optimism, self-efficacy, social support) and stress mediate the effects of gratitude on resilience. Methods: 90 medical students at Witten/Herdecke University took part in the study that determined their gratitude, resilience, optimism, self-efficacy, social support and stress levels using validated questionnaires (GQ-6, RS-25, LOT-R, SWE, F-SozU, PSS). Correlations were analyzed using Pearson correlation coefficients. In addition, a multivariate regression analysis and a path analysis were calculated to determine the direct and indirect effects of gratitude on resilience. Results: Multivariate regression analysis showed that only optimism, social support and stress were significantly associated with resilience (B=0.48, 95% CI: 0.31, 0.66; B=0.23, 95% CI: 0.01, 0.44 and B=-0.02, 95% CI: -0.03, -0.001, respectively). The direct effect of gratitude on resilience was minimal and not significant in the path analysis. However, there was an indirect effect of gratitude on resilience (B=0.321; p<0.05). Mediation via the optimism variable was mainly responsible for this effect (indirect effect B=0.197; p<0.05). Conclusion: This study shows that gratitude has only a minimal direct influence on resilience. However, results indicate that optimism as a mediating factor strengthens the resilience of medical students. Against this background, it may be useful to integrate interventions that promote an optimistic attitude into medical studies in order to strengthen the mental health of future doctors in the long term.

RESUMO

Across three studies, we explored the link between an abstract mindset and subjective well-being (SWB) in participants with real and/or perceived financial scarcity. In Studies 1 and 2, samples presented real objective financial vulnerability: Adolescents from lower-middle income districts (Study 1; N = 256), and adults without higher education and with very low incomes (Study 2; N = 210). In Studies 1 and 2 participants completed a survey including measures of thinking style and SWB. In Studies 2 and 3 perception of financial difficulty and SWB were also measured. Study 3 (N = 161) used a sample of university students and employed an experimental design manipulating participants’ thinking style (i.e., concrete versus abstract mindset conditions); additionally, all participants were induced to perceive financial scarcity. Correlations revealed a significant and positive relationship between an abstract thinking style and SWB (Studies 1 and 2). Thus, these results showed that a relatively more abstract thinking style was associated with greater life satisfaction. In Studies 2 and 3 mediation analyses indicated that adults who presented a more abstract thinking style, perceived lower financial difficulties and then reported greater SWB. Overall, given that an abstract thinking style can be induced, these results offer a new intervention approach for improving the SWB of people living in situations of financial scarcity. (AU)

RESUMO

This article aimed to explore the feasibility and clinical utility of the online Unified Protocol to improve emotional regulation with women diagnosed with breast cancer. Method. Research with a quantitative, exploratory, descriptive, and interactive approach, with a quasi-experimental design, pre-posttest for paired samples. Nine women with an average age of 53 years (SD= 9.5; range from 41 to 71) participated in a psychological intervention of 12 weekly 90-minute sessions. A statistically significant change (p < 0.05) between pre and post-test measurements in Anxiety (t= 2.777; p=.024), Quality of life (Z= -2.670; p=.008), Optimism (t= -2.785; p= .024) and Positive Affect (t= -3.834; p=.005) were found. The size of the effect was moderate in Optimism and big in Anxiety, Quality of life and Positive Affect. High levels of treatment satisfaction were found. The intervention was useful to improve the emotional regulation of women with a medical condition in a pandemic context. (AU)

RESUMO

BACKGROUND: Although there is a robust relationship among social trauma, optimism, and depression, the inner mechanism of this correlation remains unclear and need to be further explored. The mainly purpose of the current study was to investigate the relationship between social trauma, optimism, and depression among college students in China. More specifically, examined the moderating role of the optimism between social trauma and depression in Chinese college students. METHODS: A sample of 464 Chinese college students (54.7% female, Mage=19.29) from three universities were selected by the convenient sampling, and the Social Trauma Questionnaire (STQ), the Optimism Questionnaire (OPQ), and the Self-Rating Depression (SDS) were completed by these Chinese undergraduates. The descriptive statistics, Pearson correlations, and hierarchical regression analysis were used to examine the results. RESULTS: (1) The social trauma was positively associated with depression, whereas the optimism was negatively associated with social trauma, and depression; (2) The social trauma had a significant correlation with depression, and the optimism could moderate the relationship between social trauma and depression. More specifically, the further study showed that there was a significant positive relation between social trauma and depression under the low optimism level, however, there was a non-significant relation between social trauma and depression under the high optimism level. CONCLUSION: The optimism is the protective mechanism of college students' mental health (e.g., depression), it could weaken the trauma that associated with social trauma among college students.

RESUMO

BACKGROUND AND OBJECTIVES: The Best Possible Self (BPS) has been found to be an effective manipulation to temporarily improve optimism and affect. The BPS has been used in different formats. In some versions, participants just write about their best possible future, while in others this is combined with imagery. An imagery only version has not been tested yet. The aim of the current study was to examine the effectiveness of three different versions of the BPS and their equivalence in improving optimism and affect. METHODS: In an online study format, participants (N = 141) were randomly assigned to one of four conditions: (1) writing and imagery BPS; (2) writing BPS; (3) imagery BPS; and (4) a typical day (TD) control condition. RESULTS: Results showed that each BPS condition significantly improved optimism (i.e. increased positive future expectancies and decreased negative future expectancies) and affect (i.e. increased positive affect and decreased negative affect). Equivalence testing showed that all online BPS conditions were equivalent in increasing optimism and affect, thereby confirming that both the writing and imagery elements of the BPS can independently from each other increase optimism and positive affect in a healthy population. LIMITATIONS: Only the immediate effects of the BPS formats on increasing optimism and affect were measured. CONCLUSIONS: The BPS manipulation can be employed in different ways for potential future exploration, depending on the research question, design and context and/or E-mental health applications for the treatment of individuals suffering from psychological complaints.

RESUMO

Anxiety remains understudied in family carers of people with dementia. Understanding factors that moderate the relationship between stressors and anxiety symptoms in this population is critical to inform interventions. This study examined whether generic experiential avoidance (AAQ-II) and experiential avoidance specific to caregiving-related thoughts and feelings (EACQ) moderate the relationship between subjective burden (ZBI-12) and anxiety symptoms (GAD-7) in carers of people with dementia. The first model (R2 = .66, ∆R2 = .03) exploring the moderating effect of AAQ-II demonstrated a significant interaction term between AAQ-II and subjective burden. The second model (R2 = .53, ∆R2 = .03), exploring the moderating effect of EACQ, demonstrated a significant interaction term between EACQ and subjective burden. These results provide evidence that carers with higher levels of experiential avoidance may be particularly prone to the negative effect of subjective burden on anxiety symptoms. Clinical implications for assessment of experiential avoidance and its treatment in carers of people with dementia are discussed.

RESUMO

People have been shown to be optimistically biased when their future outcome expectancies are assessed. In fact, we display optimism bias (OB) toward our own success when compared to a rival individual's (personal OB [POB]). Similarly, success expectancies for social groups we like reliably exceed those we mention for a rival group (social OB [SOB]). Recent findings suggest the existence of neural underpinnings for OB. Mostly using structural/functional MRI, these findings rely on voxel-based mass-univariate analyses. While these results remain associative in nature, an open question abides whether MRI information can accurately predict OB. In this study, we hence used predictive modelling to forecast the two OBs. The biases were quantified using a validated soccer paradigm, where personal (self versus rival) and social (in-group versus out-group) forms of OB were extracted at the participant level. Later, using gray matter cortical thickness, we predicted POB and SOB via machine-learning. Our model explained 17% variance (R2 = 0.17) in individual variability for POB (but not SOB). Key predictors involved the rostral-caudal anterior cingulate cortex, pars orbitalis and entorhinal cortex-areas that have been associated with OB before. We need such predictive models on a larger scale, to help us better understand positive psychology and individual well-being.

RESUMO

BACKGROUND: Negative emotional eating (EE) is associated with unfavorable behavioral and health outcomes. Understanding its association with positive factors, such as optimism, may shed light into novel interventions. We examined the association between optimism and negative EE in US Caribbean Latinx adults, a population disproportionately exposed to adversity. METHOD: This cross-sectional analysis used data from the Latino Health and Well-being Study (21-84 years; n = 579). Optimism was measured with the Life Orientation Test-Revised version. EE was measured with the Three-Factor Eating Questionnaire R18-V2. Adjusted Poisson models with robust error variance estimated prevalence ratios (PR). RESULTS: The proportion of individuals reporting high EE was greater in the low (39.0%) and moderate (36.8%) optimism groups than that in the high optimism group (24.8%; p = 0.011). Individuals with high optimism (vs. low) were less likely to report high EE over no EE (PR = 0.68; 95% CI = 0.53-0.88). CONCLUSION: High optimism was negatively associated with high EE. Future studies are needed to confirm our findings and test interventions promoting optimism for preventing negative EE in US Caribbean Latinx adults.

RESUMO

Las personas con dolor crónico cambian la forma de realizar las actividades cotidianas, diferenciándose diversos patrones, entre ellos, la secuenciación de actividades (pacing). La bibliografía acerca de la relación entre pacing y afecto muestran resultados contradictorios. El objetivo de este estudio fue contrastar experimentalmente, en una muestra de 145 estudiantes, si la inducción de afecto positivo vs negativo influía en la elección del tipo de “pacing” (“pacingpara aumentar la productividad” y “pacingpara reducir el dolor”) cuando los participantes eran expuestos a dolor, controlando las variables optimismo y catastrofismo. Los resultados de la regresión logística multinomial no mostraron relación entre las variables. El pacing es una estrategia de intervención presente en todos los modelos de intervención en dolor crónico y, por tanto, es relevante seguir profundizando acerca del rol del afecto en relación al mismo.(AU)


People with chronic pain often change the way they carry out their daily activities according to different patterns, among which are pacing strategies. Cross-sectional studies on the association between pacing andaffectshow contradictory results. The study aim was to experimentally test whether the induction of positive affect vs negative affect would influence the choice of the type of pacing (pacing to increase productivity or pacing to reduce pain) when the participants were exposed to pain, while controlling for the variables optimism and catastrophism. The study participants comprised a sample of 145 undergraduates. The results ofmultinomial logistic regression showed that there was no association between the variables. Pacing is an intervention strategy in all chronic pain intervention models, and thus it is relevant to continue investigating the role of affect in relation to pacing.(AU)

RESUMO

COVID-19 in Malaysia has significantly affected the higher education system of the country and increased the level of distress among university students. Empirical evidence proposed that environment quality is associated with university students' life satisfaction during COVID-19. It was found that hope and optimism are linked with greater life satisfaction in general. Although past literature has reported the effects of hope and optimism on life satisfaction, there are limited studies examining the underlying mechanism among Malaysian private university students. Therefore, the current study offers the preliminary understanding of the intervening role of hope and optimism on the relationship between environmental quality and life satisfaction among private university students in Malaysia. A total of 133 private university students in Malaysia were recruited through homogenous convenience sampling. Partial least square structure equation modeling (SmartPLS) was used to analyze the mediation models. The results revealed that only hope mediated the relationship between environmental quality and life satisfaction, but not optimism. Hence, it is proposed that mental health providers should focus on providing hope-related interventions to university students in confronting COVID-19 challenges and ultimately improving life satisfaction.

RESUMO

Prior research has found the differential strength of optimism and pessimism in predicting physical health. However, whether similar findings would be obtained in predicting subjective well-being and the possible underlying mechanisms are still unclear. This study examined the relative strength of optimism and pessimism in predicting adolescent life satisfaction and depression, and further explored the possible mediating mechanisms from the perspective of emotion regulation. A sample of 2672 adolescents (Mage = 13.54 years, SD = 1.04; 55.60% boys) completed a survey assessing optimism and pessimism, the habitual use of reappraisal and acceptance strategies, life satisfaction, and depression. The results from dominance analysis revealed that the presence of optimism was more powerful than the absence of pessimism in predicting adolescent life satisfaction, while the absence of pessimism was more powerful than the presence of optimism in predicting adolescent depression. Moreover, mediation models showed that reappraisal and acceptance mediated both the link between optimism and life satisfaction and the link between pessimism and depression. These findings suggest possible avenues for intervening in different aspects of adolescent subjective well-being.

RESUMO

A large literature at the crossroads of biology and cognitive psychology has shown that individuals hold generally positive expectations about future events. Despite this evidence, to date it remains unclear whether optimism has positive or negative implications for entrepreneurial activities. We examine this question in the context of the Covid-19 pandemic, which provides a unique way to study the role of optimism on the (in)ability of firms to overcome exogenous shocks. Using a large-scale longitudinal survey covering 1,632 UK firms, we find that entrepreneurs who score high on optimism were more likely to innovate and make organizational changes to their firms during the Covid-19 outbreak. Moreover, optimistic entrepreneurs experienced higher revenue growth during the pandemic. Collectively, our study sheds light on one of the psychological factors explaining why some firms can prosper and some others struggle in the wake of an external shock.

RESUMO

The initial waves of the coronavirus pandemic amplified feelings of depression, psychological fatigue and pessimism for the future. Past research suggests that nostalgia helps to repair negative moods by boosting current and future-oriented positive affect, thereby strengthening psychological resilience. Accordingly, the present study investigated whether nostalgia moderated the relationship between pandemic experience and individual differences in mood and optimism. Across two studies we assessed psychosocial self-report data from a total of 293 online participants (22-72 years old; mean age 38; 109 females, 184 males) during the first two waves of the pandemic. Participants completed comprehensive questionnaires that probed state and trait characteristics related to mood and memory, such as the Profile of Mood States, Nostalgia Inventory and State Optimism Measure. Our findings indicate that during the initial wave of coronavirus cases, higher levels of nostalgia buffered against deteriorating mood states associated with concern over the pandemic. Nostalgia also boosted optimism for participants experiencing negative mood, and optimism predicted subjective mood improvement one week later. This shielding effect of nostalgia on optimism was replicated during the second wave of coronavirus cases. The present findings support the role of nostalgia in promoting emotional homeostasis and resilience during periods of psychological distress.

RESUMO

Objective: Positive psychosocial factors may protect against cardiovascular disease (CVD). We aimed to determine the association of optimism and pessimism with CVD events in community-dwelling older adults. Methods: 11,651 adults aged 70 years and over, participants of the ASPREE Longitudinal Study of Older Persons (ALSOP), were followed-up for 4.7 years (median). The association of optimism and pessimism (assessed as separate constructs by revised Life Orientation Test) and incident CVD events (composite and components) was assessed by Cox regression adjusted for demographic, socioeconomic and health factors. Results: No association was observed between optimism and pessimism with composite CVD events. Being more pessimistic was associated with a greater risk of fatal coronary heart disease, while being more optimistic was associated with a lower risk of non-fatal myocardial infarction. Conclusions: Optimism and pessimism may shape cardiovascular health of older adults; and we argue these psychosocial factors should be researched as separate constructs.

RESUMO

The Fatalism Scale is a valid and reliable instrument for measuring fatalistic beliefs about health. However, no previous studies have been conducted to verify its psychometric properties across different populations and, most importantly, during a public health emergency. Hence, this study aimed to examine the factorial structure, reliability, construct validity, and accuracy of measurement of the Fatalism Scale during the COVID-19 pandemic among Italian-speaking people. The total sample was comprised of 300 participants. Both exploratory and confirmatory factor analyses were performed. Construct validity was estimated by comparing fatalism scores with two theoretically-related constructs (i.e., optimism, locus of control). The test information function was analyzed to evaluate the accuracy of measurement based on item response theory (IRT). Differences in fatalism scores across gender were examined by performing MANOVAs. Results show a four-factor model: Luck, Powerlessness, Predetermination, and Pessimism with adequate fit indices and satisfactory internal consistency. Data support the expected relationships between fatalism subscales and related measures. The test information function and standard error curve provide the largest amount of information around = zero and two standard deviations above the mean in the latent trait. Significant differences across gender are observed in Luck and Pessimism subscales. Our study suggests that the Fatalism Scale is a valuable tool for assessing fatalism during an acute health crisis among Italian-speaking people. This instrument might be useful for assessing fatalism during future waves of the COVID-19 pandemic and other public health crises (AU)

RESUMO

This study examines the mediating role of work-to-family conflict and family-to-work conflict between the Big Five personality traits and mental health thereby enhancing theoretical development based upon empirical evidence. Integrating Conservation of Resources theory with the self-medication hypothesis, we conducted a mega-meta analytic path analysis examining the relationships among employees' Big Five traits, work-to-family conflict and family-to-work conflict, anxiety and depression, and substance use. We produced a ten-by-ten synthetic correlation matrix from existing meta-analytic bivariate relationships to test our sequential mediation model. Results from our path analysis model showed that agreeableness and conscientiousness predicted substance use via mediated paths through both work-to-family conflict and family-to-work conflict and sequentially through depression as well as through family-to-work conflict followed by anxiety. Extroversion and openness-to-experience had relatively weaker influences on substance use through work-to-family conflict, anxiety, and depression. Neuroticism was the strongest driver of the two forms of conflict, the two mental health conditions, and substance use. From this model it can be inferred that work-to-family conflict and family-to-work conflict may be generative mechanisms by which the impact of personality is transmitted to mental health outcomes and then to substance use when analyzed via a Conservation of Resources theory lens.

RESUMO

OBJECTIVES: Research on older adults often focuses on mitigating health risks, and less is known about protective factors that contribute to longer, healthier lives. We examine longitudinal associations between psychological well-being and mortality among a national sample of older adults and test competing hypotheses about whether the education/mortality association depends on the level of psychological well-being. METHOD: We use six waves (2006-2016) of the Health and Retirement Study, a national sample of adults over age 50 (n = 21,172), with 14 years of mortality follow-up. Psychological well-being is measured up to three times and includes positive affect, life satisfaction, purpose in life, social support, and optimism. Discrete-time survival models examine (a) the association between time-varying psychological well-being and mortality, and (b) interactions between psychological well-being and education on mortality. RESULTS: Higher purpose in life, positive affect, optimism, social support, and life satisfaction predicted lower mortality. A 1 SD increase in most measures of psychological well-being was associated with a 2-4 year increase in life expectancy at age 50. Positive affect and purpose in life moderated the education/mortality association-the inverse association between education and mortality was stronger for those with high psychological well-being. CONCLUSIONS: We find strong evidence that psychological well-being predicts lower mortality risk and modifies the association between education and mortality. The inverse association between education and mortality becomes stronger at higher levels of purpose in life and positive affect. Therefore, efforts to promote life satisfaction, social support, and optimism may support longer lives without widening education disparities.

RESUMO

The current study sought to create a developmental bibliotherapy material database (DBMD) and examine the effectiveness of developmental bibliotherapy on subjective well-being of older adults living in nursing homes. Based on the reading needs of older adults, we developed a DBMD, which included 327 materials with five themes: Health Care, Current Affairs and Politics, Historical Biographies, Geriatric Culture, and Psychological Adjustment. Fifty-four single materials were randomly selected from the DBMD to perform the intervention. This study used a quasi-experimental, single-group pre-/post-survey approach. Sixty-four older adults participated in the study for 6 weeks. Immediately before and after the intervention, older adults completed the Optimism-Pessimism Scale and Memorial University of Newfoundland Scale of Happiness. There were significant improvements in older adults' optimistic tendency and subjective well-being (p < 0.05). Reading materials in the DBMD promoted older adults' optimistic attitude toward life, reduced negative emotions, and improved subjective well-being.

RESUMO

The replay of task-relevant trajectories is known to contribute to memory consolidation and improved task performance. A wide variety of experimental data show that the content of replayed sequences is highly specific and can be modulated by reward as well as other prominent task variables. However, the rules governing the choice of sequences to be replayed still remain poorly understood. One recent theoretical suggestion is that the prioritization of replay experiences in decision-making problems is based on their effect on the choice of action. We show that this implies that subjects should replay sub-optimal actions that they dysfunctionally choose rather than optimal ones, when, by being forgetful, they experience large amounts of uncertainty in their internal models of the world. We use this to account for recent experimental data demonstrating exactly pessimal replay, fitting model parameters to the individual subjects' choices.

RESUMO

Dispositional optimism is a potentially modifiable factor and has been associated with multiple physical health outcomes, but its relationship with depression, especially later in life, remains unclear. In the Nurses´ Health Study (n = 33,483), we examined associations between dispositional optimism and depression risk in women aged 57-85 (mean = 69.9, SD = 6.8), with 4,051 cases of incident depression and 10 years of follow-up (2004-2014). We defined depression as either having a physician/clinician-diagnosed depression, or regularly using antidepressants, or the presence of severe depressive symptoms using validated self-reported scales. Age- and multivariable-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (95% CIs) across optimism quartiles and for a 1-standard deviation (SD) increment of the optimism score. In sensitivity analyses we explored more restrictive definitions of depression, potential mediators, and moderators. In multivariable-adjusted models, women with greater optimism (top vs. bottom quartile) had a 27% (95%CI = 19-34%) lower risk of depression. Every 1-SD increase in the optimism score was associated with a 15% (95%CI = 12-18%) lower depression risk. When applying a more restrictive definition for clinical depression, the association was considerably attenuated (every 1-SD increase in the optimism score was associated with a 6% (95%CI = 2-10%-) lower depression risk. Stratified analyses by baseline depressive symptoms, age, race, and birth region revealed comparable estimates, while mediators (emotional support, social network size, healthy lifestyle), when combined, explained approximately 10% of the optimism-depression association. As social and behavioral factors only explained a small proportion of the association, future research should investigate other potential pathways, such as coping strategies, that may relate optimism to depression risk.
