Powe conceptually defined "cancer fatalism" and developed the Powe Fatalism Inventory (PFI) to operationalize cancer fatalism. Researchers report disparate underlying factor structures, and sparse evidence supports the validity and reliability of the PFI. Therefore, the purpose of this study was to examine the psychometric properties of the PFI. Specifically, we aimed to examine its (a) underlying dimensions, (b) internal consistency, and (c) construct validity. We recruited 400 post-menopausal women, 50-64 years old, for a study on mammographic breast density. Women completed the 15-item PFI and the 8-item Champion Breast Cancer Fear Scale (CBCFS). We conducted item analyses and exploratory factor analysis and evaluated different factor structures. We estimated internal consistency and conducted Pearson correlations between PFI and CBCFS scores to examine construct validity. We found a two-factor solution. Factor 1, Predetermination, had an eigenvalue of 5.2 and explained 43% of the variance with factor loadings ranging from -0.59 to -0.83. Factor 2, Pessimism, had an eigenvalue of 4.5 and explained 15.2% of the variance with factor loadings ranging from 0.63 to 0.77. Both factors together explained 58.2% of the variance. There were no cross-loading items and no item loadings below 0.4. The two subscales both had alphas of .89. Cancer fatalism scores were positively related to fear scores (317, < .001, 95% CI: .222, .406). Using PFI responses from postmenopausal women, we determined that the two-factor solution was the most parsimonious yet theoretically sound factor structure underlying the 15 items of the PFI. The subscales Predetermination (Factor 1; six items) and Pessimism (Factor 2; nine items) were internally consistent with the evidence of the construct validity.

Review
BACKGROUND
Adhering to varenicline has been shown to significantly improve the chances of successfully quitting smoking, with studies indicating a twofold increase in 6-month quit rates. However, despite its potential benefits, many individuals struggle with maintaining good adherence to varenicline; thus there is a need to develop scalable strategies to help people adhere. As a first step to inform the development of an intervention to improve adherence to varenicline, we conducted a rapid literature review to identify: 1) modifiable barriers and facilitators to varenicline adherence, and 2) behaviour change techniques associated with increased adherence to varenicline.
METHODS
We searched MEDLINE, Embase, APA PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials for relevant studies published between 2006 and 2022. Search terms included "varenicline," "smoking cessation," and "adherence," and their respective subject headings and synonyms. We screened and included studies reporting modifiable determinants of adherence to varenicline and then assessed quality, extracted modifiable determinants and mapped them to the Theoretical Domains Framework version 2 and the Behaviour Change Technique Taxonomy version 1.
RESULTS
A total of 1,221 titles were identified through the database searches; 61 met the eligibility criteria. Most of the studies were randomized controlled trials and predominantly focused on barriers to varenicline. Only nine studies explicitly mentioned behaviour change techniques used to help varenicline adherence. Eight domains were identified as barriers to varenicline adherence (behavioural regulation, memory, goals, intentions, beliefs about capabilities, beliefs about consequences, optimism/pessimism, and environmental context) and five as facilitators (knowledge, behavioural regulation, beliefs about capabilities, social influences, and environmental context).
CONCLUSIONS
This study identifies barriers and facilitators that should be addressed when developing a complex adherence intervention tailored to patients' needs based on modifiable determinants of medication adherence, some of which are under- used by existing adherence interventions. The findings from this review will inform the design of a theory-based healthbot planned to improve varenicline adherence in people undergoing smoking cessation treatment.

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.

BACKGROUND
Perceptions of personal attributes as less malleable are associated with more severe depression symptoms and less active coping in youth. Perceptions of depression itself as relatively fixed have been linked to more severe depression symptoms; however, it is not known how beliefs about depression relate to active and avoidant coping behaviors in particular.
METHODS
We gathered information about beliefs about depression and activation and avoidance behaviors among 104 adolescents with high depression symptoms. The primary depression belief examined was prognostic pessimism, or the belief that depression is relatively permanent. We calculated correlations between this belief and activation and avoidance/rumination behaviors.
RESULTS
Prognostic pessimism was negatively correlated with behavioral activation scores (r = -0.31; p = .001), and was positively correlated with behavioral avoidance/rumination scores (r = 0.30; p = .002).
LIMITATIONS
This data was cross-sectional, and relied on self-report measures of depression beliefs and behaviors.
CONCLUSIONS
Adolescents who believe that depression is relatively permanent might feel less motivated to engage in effortful activation behaviors, instead favoring avoidance. These results may help elucidate the ways in which malleability beliefs relate to mental health outcomes among adolescents, and highlight prognostic pessimism as a potential treatment target for reducing depressogenic behaviors.

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.

Depression is a psychiatric disorder characterized by anxiety, pessimism, and suicidal tendencies, which has serious impact on human's life. In this paper, we use Granger causality index based on polynomial kernel as network node connectivity coefficient to construct brain networks from the magnetoencephalogram (MEG) of 5 depressed patients and 11 healthy individuals under positive, neutral, and negative emotional stimuli, respectively. We found that depressed patients had more information exchange between the frontal and occipital regions compared to healthy individuals and less causal connections in the parietal and central regions. We further analyzed the topological properties of the network revealed and found that depressed patients had higher average degrees under negative stimuli ( = 0.008) and lower average clustering coefficients than healthy individuals ( = 0.034). When comparing the average degree and average clustering coefficient of the same sample under different emotional stimuli, we found that depressed patients had a higher average degree and average clustering coefficient under negative stimuli than neutral and positive stimuli. We also found that the characteristic path lengths of patients under negative and neutral stimuli significantly deviated from small-world network. Our results suggest that the analysis of polynomial kernel Granger causality brain networks can effectively characterize the pathology of depression.

INTRODUCTION
Major depressive disorder (MDD) is a common, frequently recurrent condition associated with decreased well-being and increased healthcare-related costs. Mixed-methods research provides multiple ways of illustrating the phenomenon to better understand patient experience, including where treatment is not working, referred to here as treatment-resistant depression (TRD).
METHODS
A mixed-methods study investigated the experiences of people with symptomatic MDD, symptomatic TRD or TRD in remission, surveying 148 adults recruited from English clinical sites to measure symptom severity (Patient Health Questionnaire-9 [PHQ-9]), HRQoL (EQ-5D-5L/World Health Organisation Brief Assessment of QoL [WHOQOL-BREF]) and work productivity/activity impairment (WPAI:D). Interviews with 26 survey respondents were analysed thematically. Integrated datasets explored areas of convergence and divergence, with concepts mapped against the EQ-5D-5L.
RESULTS
Qualitative data explained low WHOQOL-BREF domain scores and the interrelation of psychological, emotional, cognitive and physical difficulties. Tiredness, lack of energy and motivation impacted daily activities, socialising and career goals. Low work performance scores were explained by poor concentration, decision-making and motivation. Participants also described the influence of social support and housing insecurity. Only 19 % of HRQoL qualitative codes mapped to the EQ-5D-5L. Themes dominant in patients with TRD were inability to cope, self-care challenges, dissatisfaction with mental health services and treatment pessimism.
LIMITATIONS
Limited data collected on people with TRD in remission.
CONCLUSIONS
The EQ-5D-5L and WPAI:D likely underestimate how depression impacts the HRQoL and work of people with MDD or TRD. Qualitative data suggest increased distress for people with TRD compared to those with MDD. Clinical management and treatment access decisions should consider the broader impacts of depression and environmental factors affecting the patient's experience.

OBJECTIVES
Studies of retrospective personality change with dementia consistently find caregivers report large changes in personality (e.g., increases in neuroticism) of their care recipients compared to before dementia. This work seeks to replicate the established pattern of personality change, extend it to change in psychological distress, well-being, and social connection, and evaluate whether changes vary by stage of dementia.
METHODS
Caregivers of people with dementia (N = 188) reported on the psychological and social health of their care recipient currently and how they were before they developed dementia. Personality was measured as five factor model traits. Psychological distress was measured as symptoms of depression and anxiety, perceived stress, and pessimism. Psychological well-being was measured as purpose in life, life satisfaction, happiness, self-efficacy, and optimism. Social connection was measured as loneliness, belonging, social support, and social strain.
RESULTS
There were substantial increases in neuroticism (d = 1.14) and decreases in the other four personality traits (d range=-0.85 to -1.37). There were significant increases in psychological distress (e.g., d = 1.07 for depression) and substantial decreases in well-being (e.g., d=-1.18 for purpose in life) and social connection (e.g., d=-1.12 for belonging). Change was apparent across dementia stage and generally larger in more severe dementia.
DISCUSSION
In addition to personality, there are large retrospective changes in psychological distress, well-being, and social connection with dementia. These quantitative findings complement clinical observations of the natural history of psychosocial changes in people with dementia, and can inform families, clinicians, and researchers on commonly observed changes and improve interventions to mitigate dementia burden.

Review
Antisocial personality disorder and therapeutic pessimism - how can mentalization-based treatment contribute to an increased therapeutic optimism among health professionals?
Antisocial personality disorder (ASPD) is associated with therapeutic pessimism among health professionals. Several variables are associated with obstacles in therapist's willingness to treat ASPD. Variables that are relevant are (i) confusion associated with the term ASPD, (ii) characteristics of the disorder, (iii) attitudes, experiences, and knowledge clinicians possess, and (iv) insufficient management of countertransference. We assume that therapeutic pessimism is related to the lack of evidence-based, effective treatment for individuals with ASPD. This is problematic because ASPD is associated with large socio-economic costs and considerable suffering for the individual and the society. Mentalization-based treatment (MBT) was developed in treating borderline personality disorder (BPD) and is now considered an effective treatment for this group. Mentalization is defined as the process by which individuals make sense of themselves and others in terms of subjective states and mental processes. This ability affects an individual's psychological functioning, mental health, self-organization, and interpersonal relationships. The overall goal of MBT is to strengthen the individual's mentalizing abilities and facilitate more adaptive handling of problematic, internal states. Recently, a version of MBT tailored for individuals with ASPD (MBT-ASPD) has been developed. The purpose of this review is to investigate how MBT-ASPD relates to the major obstacles that contribute to the therapeutic pessimism toward this group. Despite a limited evidence base, preliminary studies indicate promising results for MBT-ASPD. More research is still required, this review suggests MBT-ASPD can contribute to increased therapeutic optimism and demonstrate specific characteristics of MBT-ASPD that contribute to management of therapeutic pessimism.

This work seeks to replicate the established pattern of personality change, extend it to change in psychological distress, well-being, and social connection, and evaluate whether changes vary by stage of dementia.
METHODS
Caregivers of people with dementia (=194) reported on the psychological and social health of their care recipient currently and how they were before they developed dementia. Personality was measured as five factor model traits. Psychological distress was measured as symptoms of depression and anxiety, perceived stress, and pessimism. Psychological well-being was measured as purpose in life, life satisfaction, happiness, self-efficacy, and optimism. Social connection was measured as loneliness, belonging, social support, and social strain.
RESULTS
There were substantial increases in neuroticism (=1.10) and decreases in the other four personality traits ( range=-.82 to -1.31). There were significant increases in psychological distress (e.g., =1.05 for depression) and substantial decreases in well-being (e.g., =-1.07 for purpose in life) and social connection (e.g., =-1.09 for belonging). Change was apparent across dementia stage and generally larger in more severe dementia.
