Insomnia is prevalent in up to 40% of breast cancer survivors. Few studies have examined pessimism and dietary factors as risk factors for insomnia among breast cancer survivors. We leveraged a cohort of 2944 breast cancer survivors who enrolled in the Women’s Healthy Eating and Living study; these survivors provided dietary, insomnia, mental health, demographic, and lifestyle information at baseline and at 1- and 4-year follow-up assessments. Insomnia symptoms were assessed using the Women’s Health Initiative (WHI)-Insomnia Rating Scale, and pessimism was assessed using the Life Orientation Test Revised (LOT-R). Total calorie intake and acid-producing diets were assessed using 24 h dietary recalls. Multivariable-adjusted generalized estimating equation (GEE) models were used to test the independent and joint effects of psychological and dietary factors on insomnia. In the multivariable model, women in the third tertile of pessimism had greater odds (OR = 1.57 95% CI [1.37−1.79]) of insomnia when compared to women in the lowest tertile. Total calorie intake and acid-producing diets were each independently and significantly associated with insomnia symptoms. Further, pessimism and calorie intake/acid-producing diets were jointly associated with insomnia. For instance, women with pessimism scores in tertile 3 and total calorie intakes < median reported 2 times the odds (OR = 2.09; 95% CI [1.51−3.47]) of insomnia compared to women with pessimism score in tertile 1 and calorie intakes < median. Our results highlight the need for patient care regarding mental health, and recommendations of healthy dietary intakes for breast cancer survivors.

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 ( = 13.54 years, = 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.

OBJECTIVE
To test whether 2 conceptually overlapping constructs, dispositional optimism (generalized positive expectations) and optimistic bias (inaccurately low risk perceptions), may have different implications for smoking treatment engagement.
METHOD
Predominantly Black, low-income Southern Community Cohort study smokers (n = 880) self-reported dispositional optimism and pessimism (Life Orientation Test-Revised subscales: 0 = neutral, 12 = high optimism/pessimism), comparative lung cancer risk (Low/Average/High), and information to calculate objective lung cancer risk (Low/Med/High). Perceived risk was categorized as accurate (perceived = objective), optimistically-biased (perceived < objective), or pessimistically-biased (perceived > objective). One-way ANOVAs tested associations between dispositional optimism/pessimism and perceived risk accuracy. Multivariable logistic regressions tested independent associations of optimism/pessimism and perceived risk accuracy with cessation motivation (Low/High), confidence (Low/High), and precision treatment attitudes (Favorable/Unfavorable), controlling for sociodemographics and nicotine dependence.
RESULTS
Mean dispositional optimism/pessimism scores were 8.41 ( = 2.59) and 5.65 ( = 3.02), respectively. Perceived lung cancer risk was 38% accurate, 27% optimistically-biased, and 35% pessimistically-biased. Accuracy was unrelated to dispositional optimism ((2, 641) = 1.23, = .29), though optimistically-biased (vs. pessimistically-biased) smokers had higher dispositional pessimism ((2, 628) = 3.17, = .043). Dispositional optimism was associated with higher confidence (Adjusted odds ratio [A] = 1.71, 95% CI [1.42, 2.06], < .001) and favorable precision treatment attitudes (A = 1.66, 95% CI [1.37, 2.01], < .001). Optimistically-biased (vs. accurate) risk perception was associated with lower motivation (A = .64, 95% CI [.42, .98], = .041) and less favorable precision treatment attitudes (A = .59, 95% CI [.38, .94], = .029).
CONCLUSIONS
Dispositional optimism and lung cancer risk perception accuracy were unrelated. Dispositional optimism was associated with favorable engagement-related outcomes and optimistically-biased risk perception with unfavorable outcomes, reinforcing the distinctiveness of these constructs and their implications for smoking treatment.

Review
Shortage of organ donors is the most important obstacle standing in the way of lifesaving organ transplantation in a myriad of patients suffering from end-stage organ failure. It is vital that the transplant societies and associated appropriate authorities develop strategies to overcome the unmet needs for organ donation. The power of prominent social media (SoMe) platforms such as Facebook, Twitter, and Instagram, which reach millions of people, can increase awareness, provide education, and may ameliorate the pessimism toward organ donation among the general population. Additionally, public solicitation of organs may be helpful for waitlisted candidates for organ transplantation, who cannot find a suitable donor among near relations. However, the use of SoMe for organ donation has several ethical issues. This review attempts to highlight the advantages and limitations of using social media in the context of organ donation for transplantation. Some suggestions on the best utilization of social media platforms for organ donation while balancing ethical considerations have been highlighted here.

BACKGROUND
Optimism is a disposition characterised by positive future expectancies, while pessimism is characterised by expecting the worst. High optimism and low pessimism promote the health of older adults and may potentiate full engagement in life. We identified socioeconomic, behavioural, and social factors associated with optimism and pessimism in older adults.
METHODS
Participants included 10,146 community-dwelling, apparently healthy Australian adults aged 70 years and over from the ASPREE Longitudinal Study of Older Persons (ALSOP). Optimism and pessimism were measured using the revised Life Orientation Test. Cross-sectional ordinal logistic regression was used to determine the socioeconomic, behavioural, and social health factors associated with optimism and pessimism.
RESULTS
Higher education, greater physical activity, lower loneliness, and volunteering were associated with higher optimism and lower pessimism. Low social support was associated with higher pessimism. Higher socioeconomic advantage, greater income, and living alone were associated with lower pessimism. Women were more optimistic and less pessimistic than men. The association of age, smoking status, and alcohol consumption with optimism and pessimism differed for men and women.
CONCLUSIONS
Factors associated with higher optimism and lower pessimism were also those demonstrated to support healthy ageing. Health-promotion action at the individual level (e.g., smoking cessation or regular physical activity), health professional level (e.g., social prescribing or improving access and quality of care for all older adults), and community level (e.g., opportunities for volunteer work or low-cost social activities for older adults) may improve optimism and reduce pessimism, possibly also promoting healthy ageing.

The Liar sentence , which reads ' is not true', can be used to produce an apparently valid argument proving that is not true and that is true. There has been increasing recognition of the appeal of contextualist solutions to the Liar paradox. Contextualist accounts hold that some step in the reasoning induces a context shift that causes the apparently contradictory claims to occur at different contexts. Attempts at identifying the most promising contextualist account often rely on , which seek to isolate a step at which the context cannot be claimed to have shifted or must have shifted. The literature contains a number of timing arguments that draw incompatible conclusions about the location of the context shift. I argue that no existing timing arguments succeed. An alternative strategy for assessing contextualist accounts evaluates the plausibility of their explanations of why the context shifts. However, even this strategy yields no clear verdict about which contextualist account is the most promising. I conclude that there are some grounds for optimism and for pessimism about the potential to adequately motivate contextualism.

BACKGROUND AND OBJECTIVES
Positive and negative changes in outlook represent psychological changes that are the results of the cognitive processing of stressful and traumatic events by an individual. The objectives of the study were (1) to determine the level of occurrence and types of positive and negative changes in connection with the COVID-19 pandemic among adults in Slovakia and (2) to study the role of personality factors such as hope (dispositional and perceived) and life orientation (optimism and pessimism) in the prediction of positive and negative changes in adults during the fourth pandemic wave.
METHODS
A Short Form of the Changes in Outlook Questionnaire (CiOQ-S), the Dispositional Hope Scale (DHS), the Perceived Hope Scale (PHS), and the Life Orientation Test (LOT-R) were administered. The research sample consisted of 102 participants, whose ages ranged from 20 to 65 years ( = 38.90, = 14.28). The research design was quantitative, exploratory, and confirmatory.
RESULTS
In total, 95% of participants reported positive changes related to COVID-19. Concurrently, up to 70% of these participants also reported negative changes from the impact of the pandemic. Only 25% of participants reported positive changes without noticing any negative perception of the consequences of the pandemic. Overall, 68% of participants reported negative changes related to COVID-19. Only 29% of participants reported negative changes without noticing any positive perception of the consequences of the pandemic. In total, up to 86% of participants agreed with experienced psychological changes (positive or negative) as a result of the COVID-19 pandemic. The high prevalence of positive changes along with the relatively high prevalence of negative changes related to the COVID-19 pandemic outline the question of whether reported positive changes represent real or illusory growth. Optimism and pessimism were found to be significant independent predictors of positive changes related to the COVID-19 pandemic. Hope was identified as a significant independent predictor of negative changes related to the COVID-19 pandemic.

INTRODUCTION
Recent meta-analytic research suggests that the absence of pessimism could be a stronger predictor of physical health than the presence of optimism. The present study examined the role of subjective well-being in the effects of optimism and pessimism on physical health in romantic couples. It was hypothesized that pessimism would be more strongly associated with both well-being and health than optimism, intra- and interpersonally. Subjective well-being was also expected to explain variance in the associations between optimism, pessimism, and health.
METHODS
A baseline sample of 153 opposite-sex couples completed various measures of subjective well-being (e.g., life satisfaction, positive and negative affect, and depressive symptoms) and physical health (e.g., subjective health, sleep efficiency, physical symptoms, cold symptoms, and chronic illness).
RESULTS
Results of actor-partner interdependence models showed that the absence of pessimism, but not the presence of optimism, was associated with better physical health at baseline and over time. Pessimism was also a stronger predictor than optimism of baseline levels in some indicators of subjective well-being. These effects were obtained intra- and interpersonally. Finally, subjective well-being explained variance in some of the effects of pessimism on levels of physical health. Implications for theory, research, and practice are discussed.

BACKGROUND
Mental health problems are very common among medical students, becoming a concern for health care professionals and educators. Despite the fact that there is a growing body of literature supporting the role of religiosity and spirituality (RS) on mental health and on positive psychology outcomes, little evidence is available among medical students, a population subjected to important distress.
AIMS
This study aimed to investigate the role of RS on the levels of optimism, pessimism, and happiness among Brazilian medical students.
METHODS
This is a cross-sectional study including medical students from the first to the eighth semester of a private medical school. The instruments used were: TOT-R for optimism and pessimism, Lyubomirsk and Lepper subjective happiness scale, and sociodemographic profile. The independent variables were Brazilian Portuguese Duke University Religiosity Scale for religiosity, Brief Spiritual Religious Coping (SRC) for negative and positive SRC; and Facit-Sp for spiritual well-being.
RESULTS
A total of 353 medical students were included (response rate 97.51%). Higher levels of intrinsic religiosity and peace were associated with greater happiness and optimism. However, negative SRC was associated with lower levels of happiness and optimism and higher levels of pessimism.
CONCLUSION
Medical students tend to use their RS as a resource for dealing with the challenges of medical school, influencing their happiness and optimism. In this context, it seems that religiousness acts in two different ways, not only have positive but also negative outcomes among the participants.
