Individual differences in free-range chicken systems are important factors influencing how birds use the range (or not), even if individuals are reared in the same environmental conditions. Here, we investigated how various aspects of the birds' behavioral and cognitive tendencies, including their optimism/pessimism, cognitive flexibility, sociability, and exploration levels, are associated with range use and how they may change over time (before and after range access). To achieve this, 100 White Leghorn laying hen chicks underwent three distinct behavioral/cognitive tests-the cognitive bias test, the detour test, and the multivariate test-prior to gaining access to the range, between 9 and 39 days of age. After range access was allowed (from day 71), birds' range use was evaluated over 7 nonconsecutive days (from 74-91 days of age). Subsequently, a subset of birds, classified as high rangers (n = 15) and low rangers (n = 15) based on their range use, underwent retesting on the same three previous tests between 94 and 108 days of age. Our results unveiled a negative correlation trend between birds' evaluation of the ambiguous cue and their subsequent range use (rho = -0.19, p = 0.07). Furthermore, low rangers were faster to learn the detour task (χ2 = 7.34, df = 1, p = 0.006), coupled with increased sociability during the multivariate test (rho = -0.23, p = 0.02), contrasting with their high-ranging counterparts, who displayed more exploratory behaviors (F[1,27] = 3.64, p = 0.06). These behavioral patterns fluctuated over time (before and after range access); however, conclusively attributing these changes to birds' aging and development or the access to the range remains challenging. Overall, our results corroborate that behavioral and cognitive individual differences may be linked to range use and offer novel perspectives on the early behavioral and cognitive traits that may be linked to range use. These findings may serve as a foundation for adapting environments to meet individual needs and improve animal welfare in the future.

BACKGROUND/OBJECTIVE
Promoting well-being is a key goal of cancer care, and it needs to be assessed using appropriate instruments. Flourishing is considered part of psychological well-being and it is commonly assessed with the Flourishing Scale (FS). To our knowledge, no studies have analyzed the psychometric properties of the FS in breast cancer patients. Our aim here was to provide validity evidence for use of the FS in this context.
METHOD
Participants were 217 Spanish women with breast cancer who completed the FS and other scales assessing positive psychology constructs (life satisfaction, positive affect, resilience, self-esteem, optimism) and indicators of psychological maladjustment (negative affect, depression, anxiety, and stress). The internal structure of the FS was analyzed using confirmatory factor analysis (CFA). We calculated the average variance extracted (AVE) to evaluate convergent validity, and both McDonald's omega and Cronbach's alpha coefficients to estimate reliability. Item analysis was performed by computing corrected item-total correlations. Validity evidence based on relationships with other variables was obtained through Pearson correlation analysis, controlling for age and cancer stage.
RESULTS
The CFA supported a single-factor structure, with adequate goodness-of-fit indices (CFI = 0.997, NNFI = 0.996, RMSEA = 0.069, and SRMR = 0.047) and standardized factor loadings ranging from 0.70 to 0.87. The value of the AVE was 0.63, and the reliability coefficient obtained with both procedures was 0.91. Corrected item-total correlations ranged from .62 to .78. Correlation analysis showed direct and strong associations between the FS score and scores on positive psychology constructs (range from 0.43 to 0.74), the strongest correlations being with positive affect and life satisfaction. The FS score was inversely correlated with scores on depression, anxiety, stress, negative affect, and pessimism (range from -0.14 to -0.52), the strongest association being with stress.
DISCUSSION
The FS is a useful tool for exploring well-being in the breast cancer context, providing useful information for psychological assessment.

OBJECTIVE
the aim of this study is to investigate the relationship between death distress, psychological adjustment, optimism, pessimism and perceived stress among nurses working during the COVID-19 pandemic.
METHOD
this study was designed as cross-sectional/cohort. The population of the study involved 408 nurses from Northern Cyprus, which are registered as full members of the Nurse Council. The sample comprised 214 nurses, who volunteered to participate in the study. The study data was collected using a web-based online survey (Demographic form, the Coronavirus Stress Measure, The Optimism and Pessimism Questionnaire, The Brief Adjustment Scale-6, The Death Distress Scale).
RESULTS
the results indicated that perceived stress significantly and negatively predicted optimism (β = -0.21, p < 0.001) and pessimism (β = 0.38, p < 0.001). Perceived stress had significant and positive predictive effects on psychological adjustment (β = 0.31, p < 0.001) and death distress (β = 0.17, p < 0.01). Further analysis results revealed that pessimism mediates the association of stress with psychological adjustment and death distress; however, optimism only mediates the effect of stress on psychological adjustment among nurses.
CONCLUSION
a low level of pessimism is effective in strengthening nurses' psychological adjustment skills againt perceived stress and death distress. Nurses should consider behavioral strategies to help reduce the level of pessimism during periods such as pandemics.
BACKGROUND
(1) High levels of perceived stress increased higher score of psychological adjustment. (2) Pessimism mediates the association of stress with adjustment and death distress. (3) Optimism only mediates the effect of stress on psychological adjustment among nurses.

Review
INTRODUCTION
The failed or partial implementation of clinical practices negatively impacts patient safety and increases systemic inefficiencies. Implementation of sepsis screening guidelines has been undertaken in many settings with mixed results. Without a theoretical understanding of what leads to successful implementation, improving implementation will continue to be ad hoc or intuitive. This study proposes a programme theory for how and why the successful implementation of sepsis screening guidelines can occur.
METHODS
A rapid realist review was conducted to develop a focused programme theory for the implementation of sepsis screening guidelines. An independent two-reviewer approach was used to iteratively extract and synthesise context and mechanism data. Theoretical context-mechanism-outcome propositions were refined and validated by clinicians using a focus group and individual realist interviews. Implementation resources and clinical reasoning were differentiated in articulating mechanisms.
RESULTS
Eighteen articles were included in the rapid review. The theoretical domains framework was identified as the salient substantive theory informing the programme theory. The theory consisted of five main middle-range propositions. Three promoting mechanisms included positive belief about the benefits of the protocol, belief in the legitimacy of using the protocol and trust within the clinical team. Two inhibiting mechanisms included pessimism about the protocol being beneficial and pessimism about the team. Successful implementation was defined as achieving fidelity and sustained use of the intervention. Two intermediate outcomes, acceptability and feasibility of the intervention, and adoption, were necessary to achieve before successful implementation.
CONCLUSION
This rapid realist review synthesised key information from the literature and clinician feedback to develop a theory-based approach to clinical implementation of sepsis screening. The programme theory presents knowledge users with an outline of how and why clinical interventions lead to successful implementation and could be applied in other clinical areas to improve quality and safety.

Randomized Controlled Trial
Prior research suggests that repetitive negative thinking (RNT) negatively impacts mental health by intensifying and prolonging emotional reactivity to stress. This study investigated whether an intervention designed to reduce RNT alters emotional reactivity. Young adults with high trait RNT (N = 79) were randomly allocated to an RNT-focused intervention (smartphone app-based, 10 days) or a waiting list before exposure to a standardized stressor. The pre-registered analysis did not reveal a significant condition * time interaction for negative affect. However, exploratory analyses showed that whilst initial increases in negative affect in response to the stressor did not differ between conditions, participants in the intervention condition reported less negative affect throughout the following recovery phase. Additionally, participants in the intervention condition appraised their ability to cope with the stressor as higher and reported less RNT in the recovery phase. In contrast, the intervention did not affect biological stress responses. The findings indicate that RNT-focused interventions might have positive effects on mental health by breaking the self-reinforcing cycle of RNT, negative affect and maladaptive appraisals in response to stress. However, as findings are partly based on exploratory analyses, further research is needed to confirm whether reduced subjective stress reactivity mediates the effects of RNT-focused interventions on psychopathological symptoms.

Reputations can foster cooperation by indirect reciprocity: if I am good to you then others will be good to me. But this mechanism for cooperation in one-shot interactions only works when people agree on who is good and who is bad. Errors in actions or assessments can produce disagreements about reputations, which can unravel the positive feedback loop between social standing and pro-social behaviour. Cooperators can end up punished and defectors rewarded. Public reputation systems and empathy are two possible mechanisms to promote agreement about reputations. Here we suggest an alternative: Bayesian reasoning by observers. By taking into account the probabilities of errors in action and observation and their prior beliefs about the prevalence of good people in the population, observers can use Bayesian reasoning to determine whether or not someone is good. To study this scenario, we develop an evolutionary game theoretical model in which players use Bayesian reasoning to assess reputations, either publicly or privately. We explore this model analytically and numerically for five social norms (Scoring, Shunning, Simple Standing, Staying, and Stern Judging). We systematically compare results to the case when agents do not use reasoning in determining reputations. We find that Bayesian reasoning reduces cooperation relative to non-reasoning, except in the case of the Scoring norm. Under Scoring, Bayesian reasoning can promote coexistence of three strategic types. Additionally, we study the effects of optimistic or pessimistic biases in individual beliefs about the degree of cooperation in the population. We find that optimism generally undermines cooperation whereas pessimism can, in some cases, promote cooperation.

In six studies, we find evidence of efficiency neglect: when thinking about the effects of population growth, people intuitively focus on increased demand while neglecting the changes in production efficiency that occur alongside, and often in response to, increased demand. In other words, people tend to think of others solely as consumers, rather than as consumers as well as producers. Efficiency neglect leads to beliefs that the real costs of some consumer goods are rising when they are actually decreasing and may contribute to antiimmigration sentiments because of the fear that increasing local population creates competition for fixed resources. We demonstrate that economic pessimism and antiimmigration sentiments are reduced when people are prompted to consider their own beliefs about increased productivity over time, but are unchanged when they consider their beliefs about increases in demand. Together, these findings shed light on people's lay economic theories and suggest promising interventions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE
: Environmental deprivation, a type of childhood maltreatment, has been reported to constrain the cognitive developmental processes such as associative learning and implicit learning, which may lead to functional and morphological changes in the ventral pallidum (VP) and pessimism, a well-known cognitive feature of major depression. We examined whether neonatal isolation (NI) could influence the incidence of learned helplessness (LH) in a rat model mimicking the pessimism, and the number of vesicular glutamate transporter 2 (VGLUT2)-expressing VP cells and Penk-expressing VP cells.
METHODS
: The number of escape failures from foot-shocks in the LH test was measured to examine stress-induced depression-like behavior in rats. The number of VGLUT2-expressing VP cells and Penk-expressing VP cells was measured by immunohistochemistry.
RESULTS
: In NI rats compared with Sham rats, the incidence of LH in adulthood was increased and VGLUT2-expressing VP cells but not Penk-expressing VP cells in adulthood were decreased. VGLUT2-expressing VP cells were decreased only in the LH group of NI rats and significantly correlated with the escape latency in the LH test.
CONCLUSION
: These findings suggest that the aberrant VP neuronal activity due to environmental deprivation early in life leads to pessimistic associative and implicit learning. Modulating VP neuronal activity could be a novel therapeutic and preventive strategy for the patients with this specific pathophysiology.

Mental Health and Quality of Life in Chronic Kidney Disease Patients with Mild-to-Moderate Depression: A Retrospective Cohort Study of Mindfulness-Based Stress Reduction Therapy.
BACKGROUND
Chronic kidney disease (CKD) patients may experience pessimism, and even despair, due to long-term nature of the condition, which increases the risk of depression. Mindfulness-based stress reduction (MBSR) can relieve depression. This retrospective cohort study aimed to investigate the effects of MBSR on mental health and quality of life in CKD patients with mild-to-moderate depression, so as to provide guidance for clinical nursing programs.
METHODS
The clinical data of 100 CKD patients with mild-to-moderate depression who were treated in Jiading District Central Hospital Affiliated Shanghai University of Medicine & Health Sciences from January 2021 to March 2023 were retrospectively analyzed. Based on nursing method received, the patients were divided into the conventional group (conventional management) and the MBSR group (MBSR therapy was implemented in addition to conventional management). After matching, there were 35 cases in each group. The scores for the self-rating depression scale (SDS), Connor-Davidson Resilience Scale (CD-RISC), Five-factor Mindfulness Questionnaire (FFMQ), Pittsburgh Sleep Quality Index (PSQI), and 36-item Short Form Health Survey (SF-36) were compared between the two groups.
RESULTS
After management, the SDS and PSQI scores of the MBSR group were lower than those of the conventional group, and the CD-RISC, FFMQ and SF-36 scores were higher than those of the conventional group (p < 0.05).
CONCLUSION
MBSR can improve the mental health, sleep quality, and quality of life of CKD patients with mild-to-moderate depression, and improve psychological resilience and mindfulness.

An elderly person is the subject of changes and development of the basic conditions of his life. Older patients may experience manifestations of social aging, in which some new areas of social reality remain unexplored for them. This article analyzes dispositional optimism and locus of control, as two personal characteristics closely related to the social and psychological aspects. The aim of the study was to examine the relationship between dispositional optimism and locus of control in young and old people. During the study, 115 elderly respondents from the Gerontological Center were surveyed. The average age was 70 [52-74]. A survey of 120 students of the Krasnoyarsk State Medical University of the first, second, third and fourth years, whose average age was 20 [19-25] was conducted. The majority of elderly patients were classified as having an external locus of control (54%), while 46% had an internal locus of control. Regarding optimism, 20% of older people were optimists, 73% were pessimists, and 7% of respondents had a combination of both optimism and pessimism. The majority of young respondents also fell into the category with an external locus of control (70%), while 30% had an internal locus of control. 73% of young people were optimists, 19% were pessimists, and 8% of respondents had a combination of both optimism and pessimism. In older people, there is an inverse relationship between the indicators - the level of internality is inversely proportional to the level of optimism, which is explained by the expectation that bad events will happen more often in the future than good ones. Accordingly, it is necessary to introduce practical recommendations.
