Objective: To test whether a personality feedback intervention improves three domains of cancer self-management: self-awareness, self-efficacy, and positive affect., Methods: From 11/2020-02/2021, 372 adults diagnosed with cancer participated in a randomized controlled trial (RCT) of an intervention that entailed reading a brief personality-related excerpt during an online survey. Eligibility included self-reported age ≥ 18 years, current or past cancer diagnosis, and ability to read English. The survey included a baseline assessment with a personality questionnaire, then randomized participants to one of two groups. The intervention group (n = 184) received a personality feedback report with tailored self-care tips, whereas the control group (n = 188) received a generic reading on personality theory. At the end of the survey, participants completed outcome measures of self-awareness (primary), self-efficacy for illness management, and positive affect. General linear models tested between-group differences in changes from baseline to post-test on each outcome., Results: There was no intervention effect on self-awareness (primary outcome) or positive affect. However, compared to controls, intervention participants experienced a greater increase in self-efficacy for illness management (d = 0.33, p = 0.002), including in 2 of 3 constituent domains: self-efficacy for managing symptoms (d = 0.36, p < 0.001) and self-efficacy for managing treatments/medication (d = 0.22, p = 0.035)., Conclusion: Despite the primary outcome's null results, this was the first RCT of a personality feedback intervention to show improvements in self-efficacy for managing chronic illness. Given the important role of self-efficacy in self-management, the intervention has implications for other cancer outcomes. Follow-up studies on longer-term outcomes such as health behaviors and quality of life should be explored., Trial Registration: NCT04625439., (© 2024 The Author(s).

The Mini International Personality Item Pool (Mini-IPIP) is a brief measure of the Five-Factor Model of personality with documented validity in healthy samples of adults and could be useful for assessing personality in patient populations such as individuals with cancer. The purpose of this study was to examine the psychometric properties of the Mini-IPIP in 2 samples of adults with cancer. A sample of 369 (Sample 1) and a sample of 459 (Sample 2) adults with cancer completed an online survey including the Mini-IPIP. To assess criterion validity, Sample 2 completed measures of emotional distress. Analyses included internal consistency (Samples 1 and 2), confirmatory factor analyses (CFAs; Samples 1 and 2), and correlations and a structural regression model to examine the associations between the 5 personality factors and emotional distress (Sample 2 only). Results showed that the Mini-IPIP demonstrated levels of internal consistency and CFA model fit that were similar to previous validation studies conducted in the general population. Consistent with prior research and theory, this study also found that personality factors measured by the Mini-IPIP were associated with measures of emotional distress in Sample 2. These findings suggest the potential utility of the Mini-IPIP in both research and clinical settings involving individuals with cancer.

Personality is associated with health, but examinations in patients with illnesses are lacking. We aimed to determine whether personality-physical health associations differed between community and cancer samples. This cross-sectional study involved 168 participants without cancer, 212 men with prostate cancer, and 55 women with breast cancer. We examined whether the Big Five personality dimensions were associated with health behaviors and multiple health indicators. Higher conscientiousness and lower neuroticism were associated with better health behaviors and health ( r  = .31), with few differences between community and cancer samples. Findings call for research on the implications of personality in patients with serious illnesses.max  = .31), with few differences between community and cancer samples. Findings call for research on the implications of personality in patients with serious illnesses.

Background: Geographic disparities in access to palliative care cause unnecessary suffering near the end-of-life in low-access U.S. states. The psychological mechanisms accounting for state-level variation are poorly understood. Objective: To examine whether statewide differences in personality account for variation in palliative care access. Design: We combined 5 state-level datasets that included the 50 states and national capital. Palliative care access was measured by the Center to Advance Palliative Care 2015 state-by-state report card. State-level personality differences in openness, conscientiousness, agreeableness, neuroticism, and extraversion were identified in a report on 619,387 adults. The Census and Gallup provided covariate data. Regression analyses examined whether state-level personality predicted state-level palliative care access, controlling for population size, age, gender, race/ethnicity, socioeconomic status, and political views. Sensitivity analyses controlled for rurality, nonprofit status, and hospital size. Results: Palliative care access was higher in states that were older, less racially diverse, higher in socioeconomic status, more liberal, and, as hypothesized, higher in openness. In regression analyses accounting for all predictors and covariates, higher openness continued to account for better state-level access to palliative care ( β  = 0.428, p  = 0.008). Agreeableness also emerged as predicting better access. In sensitivity analyses, personality findings persisted, and less rural states and those with more nonprofits had better access. Conclusions: Palliative care access is worse in states lower in openness, meaning where residents are more skeptical, traditional, and concrete. Personality theory offers recommendations for palliative care advocates communicating with administrators, legislators, philanthropists, and patients to expand access in low-openness states.

Context: Physician aid in dying is a controversial topic in the U.S., and legislation exists in some states. Personality traits are associated with preferences for end-of-life care and also tend to cluster systematically across states and other geographic regions. Such clustering of personality traits could relate to legislation including physician aid in dying., Objective: To determine whether average levels of personality traits in each U.S. state differ between states with and without physician aid in dying legislation., Methods: This secondary analysis of national surveys included data on state demographics, political leanings, and state-level averages of Five-Factor Model personality traits. Wilcoxon tests and logistic regression tests were used to assess whether state-level averages in personality traits differed across states with and without physician aid in dying legislation., Results: States with physician aid in dying legislation had significantly higher average levels of the trait of openness and significantly lower average levels of the trait of neuroticism. The association with openness was no longer significant after accounting for state conservative advantage., Conclusion: The social dialogue and potential controversy surrounding physician aid in dying may be linked to aggregate differences in state personality profiles. States with physician aid in dying legislation tend to be areas where constituents are on average more open minded and experience greater emotional stability. More work is needed to ascertain whether the experiences of receiving and providing end-of-life care may differ across these regions, particularly in relation to conversations around physician aid in dying., (Copyright © 2018 American Academy of Hospice and Palliative Medicine.

Objective: To evaluate the relationship between personality and emotional distress in prostate cancer. Neuroticism and introversion were hypothesized to be associated with clinically significant symptoms of emotional distress, including depression, anxiety, and suicidal ideation., Methods: Men with a history of prostate cancer (n = 212) completed an NIH-funded cross-sectional study using well-validated measures of personality, depression, anxiety, and suicidal ideation. Covariates were age, education, time since diagnosis, comorbidity, and presence of metastases., Results: Emotional distress was reported by 37% of participants, including depression (23%), anxiety (15%), and suicidal ideation (10%). As hypothesized, men who were more neurotic were more likely to report emotional distress (44.5% vs 26.9%; OR = 2.78, P = .004), depression (31.9% vs 11.8%; OR = 4.23, P = .001), and suicidal ideation (29.4% vs 9.7%; OR = 4.15, P = .001). Introverts were more likely to report emotional distress (45.2% vs 28.7%; OR = 2.32, P = .012) and depression (30.8% vs 15.7%; OR = 2.57, P = .014). Men with metastases were more likely to report emotional distress (51.7% vs 31.2%; OR = 4.56, P < .001)., Conclusions: Neuroticism and introversion were associated with clinically significant emotional distress in men with prostate cancer. Findings suggest that, in the context of treatment for prostate cancer, patient distress reflects disease characteristics (eg, metastases presence) as well as stable personality traits. Implications for clinical care are discussed., (Copyright © 2017 John Wiley & Sons, Ltd.)

Objectives: Palliative medicine is a rewarding field, but providers encounter patient trauma on a routine basis. Compassion fatigue, marked by burnout, secondary traumatic stress, and low satisfaction may result. However, professionals differ markedly in how they respond to patient trauma. The objective of the current study was to determine whether personality traits of neuroticism and agreeableness relate to aspects of compassion fatigue, after accounting for time spent working in the field., Methods: Sixty-six palliative medicine physicians, nurses, social workers, and chaplains completed validated measures of personality traits, compassion fatigue, and work background., Results: Providers who had worked longer reported higher levels of satisfaction and lower levels of burnout. Neuroticism demonstrated strong significant associations with secondary traumatic stress and burnout ( Ps < .001). Agreeableness was significantly and strongly associated with compassion satisfaction ( P < .001). These associations held after accounting for years spent working in the field., Significance of Results: Personality traits of neuroticism and agreeableness may convey risk and resilience, respectively, for palliative care professionals. More research is needed to determine if assessing personality traits can help identify providers at risk for adverse reactions to patient trauma.

Affective forecasting often drives decision-making. Although affective forecasting research has often focused on identifying sources of error at the event level, the present investigation draws upon the "realistic paradigm" in seeking to identify factors that similarly influence predicted and actual emotions, explaining their concordance across individuals. We hypothesised that the personality traits neuroticism and extraversion would account for variation in both predicted and actual emotional reactions to a wide array of stimuli and events (football games, an election, Valentine's Day, birthdays, happy/sad film clips, and an intrusive interview). As hypothesised, individuals who were more introverted and neurotic anticipated, correctly, that they would experience relatively more unpleasant emotional reactions, and those who were more extraverted and less neurotic anticipated, correctly, that they would experience relatively more pleasant emotional reactions. Personality explained 30% of the concordance between predicted and actual emotional reactions. Findings suggest three purported personality processes implicated in affective forecasting, highlight the importance of individual-differences research in this domain, and call for more research on realistic affective forecasts.

Context: Increased focus on patient-centered care models has contributed to greater emphasis on improving quality of life at the end of life through personalized medicine. However, little is known about individual-level factors impacting end-of-life care preferences., Objectives: To examine whether the five-factor model of personality explains variation in preferences for end-of-life care in men with prostate cancer., Methods: Two hundred twelve men with a prostate cancer diagnosis (mean age = 62 years) completed a measure of the five-factor model of personality--spanning the personality dimensions of neuroticism, agreeableness, extraversion, openness, and conscientiousness--and reported on end-of-life care preferences. Cluster analyses were used to partition the sample into groups with similar care preferences. Analyses of variance and Chi-square tests were used to evaluate differences in care preferences among the groups., Results: Cluster analyses revealed three groups of participants: "comfort-oriented patients," "service-accepting patients," and "service-reluctant patients." Most (67%) were comfort oriented, preferring palliative care and opposing life support services. A subset of patients were service accepting (17%), preferring both palliative care and life support, or were service reluctant (16%), preferring neither. Service-reluctant patients endorsed significantly higher levels of neuroticism (emotional instability and negativity) than comfort-oriented patients. Comfort-oriented patients endorsed significantly higher levels of agreeableness than service-accepting patients and service-reluctant patients., Conclusion: Findings suggest that personality traits are associated with specific health care preferences. Individuals high on neuroticism are likely to report reluctance toward all forms of end-of-life care and may benefit from in-depth information about the process and likely outcomes of receiving life support and palliative care services., (Copyright © 2016 American Academy of Hospice and Palliative Medicine.

In a sample of 77 dyads, involving depressed patients at least 50 years of age and their family or friends (informants), patient illness burden and cognitive decline were associated with self-informant rating discrepancies for facets of Revised NEO Personality Inventory (NEO-PI-R) Openness and Extraversion. Informant judgments about Neuroticism and Conscientiousness were not associated with illness burden or cognitive function, underscoring the potential utility of risk-detection strategies that rely on informant-report in these two domains. Findings suggest the need for research on how patient illness severity and cognitive function affect how friends and family use or misuse information when making judgments about older depressed patients.

Deficits in gratification delay are associated with a broad range of public health problems, such as obesity, risky sexual behavior, and substance abuse. However, 6 decades of research on the construct has progressed less quickly than might be hoped, largely because of measurement issues. Although past research has implicated 5 domains of delay behavior, involving food, physical pleasures, social interactions, money, and achievement, no published measure to date has tapped all 5 components of the content domain. Existing measures have been criticized for limitations related to efficiency, reliability, and construct validity. Using an innovative Internet-mediated approach to survey construction, we developed the 35-item 5-factor Delaying Gratification Inventory (DGI). Evidence from 4 studies and a large, diverse sample of respondents (N = 10,741) provided support for the psychometric properties of the measure. Specifically, scores on the DGI demonstrated strong internal consistency and test-retest reliability for the 35-item composite, each of the 5 domains, and a 10-item short form. The 5-factor structure fit the data well and had good measurement invariance across subgroups. Construct validity was supported by correlations with scores on closely related self-control measures, behavioral ratings, Big Five personality trait measures, and measures of adjustment and psychopathology, including those on the Minnesota Multiphasic Personality Inventory-2-Restructured Form. DGI scores also showed incremental validity in accounting for well-being and health-related variables. The present investigation holds implications for improving public health, accelerating future research on gratification delay, and facilitating survey construction research more generally by demonstrating the suitability of an Internet-mediated strategy.

To examine whether adults with cancer view affective forecasting as important for treatment decisions, and to examine these perceptions among key subgroups. Adults with cancer (N = 376) completed a cross-sectional survey that included demographic and clinical characteristics, the IPIP five-factor personality measure, and a rating of the perceived importance of affective forecasting for cancer treatment decisions. Descriptive statistics characterized the importance of affective forecasting. Multivariate analyses examined whether health and personality variables were associated with affective forecasting importance. Most participants (89.6%) identified affective forecasting as important for treatment decisions. Affective forecasting was more likely to be rated as important among patients with prostate cancer (p <.001), patients lower in neuroticism (p =.02), and patients higher in agreeableness (p =.004). Conclusions/Implications: Patients believe it is important to understand how treatments will impact their emotional well-being. Oncology clinicians should discuss with patients these consequences during healthcare decision-making. [ABSTRACT FROM AUTHOR]

Self-complexity, the extent that people experience themselves as having a number of distinct and meaningful social roles, may have implications for young adults' socio-emotional adjustment to romantic life events. Based on prior research, we hypothesized that participants who reported lower self-complexity would have worse adjustment to a negative event (not having a date on Valentine's Day) but better adjustment to a positive event (having a date). Participants (N = 325) completed measures of self-complexity and depression symptom severity at study entry. Approximately a month later, at the end of the day on Valentine's Day, they completed a measure of emotion-regulation strategies and a reassessment of depression symptom severity. The hypothesized interaction was statistically significant; self-complexity was associated with better emotion-regulation (R 2 =.15, p <.001) and depression outcomes (R 2 =.05, p =.001) for non-daters, but worse outcomes for daters. Our findings suggest that self-complexity is related to self-regulation and has implications for adjustment to a range of life events. [ABSTRACT FROM AUTHOR]

Aim: Anger is a common reaction to cancer diagnosis which may impact patients’ perceptions of their prognosis and goals of care. This study tested the hypothesis that men with prostate cancer who are anger prone are pessimistic regarding their cancer prognosis. Methods: Two hundred and twelve men with a history of prostate cancer completed measures of personality traits, their prostate cancer prognosis, and their perception of their doctor’s assessment of their prognosis. Anger proneness was operationally defined by the presence of high levels (ie, above the medians) of neuroticism and disagreeableness. Results: One in 4 men with prostate cancer disagreed with their doctor about prognosis. Anger-prone participants endorsed more pessimistic perceptions of prognosis (P = .041). This significant association was maintained after accounting for potential confounders. Conclusion: Greater attention paid to patient anger regulation style and pessimistic perceptions will improve discussions about prognosis and goals of care among men with prostate cancer. Given recent calls for wider distress screening and earlier palliative care intervention in cancer settings, providers have an unprecedented opportunity to assess and respond to anger in the clinical setting. Communication could be improved through empathic statements that convey realistic optimism when appropriate, a commitment to the patient–provider relationship and a willingness to explore and address patient needs.

Objectives: Mindfulness-based stress reduction (MBSR) is a promising intervention for older adults seeking to improve quality of life. More research is needed, however, to determine who is most willing to use the four techniques taught in the program (yoga, sitting meditation, informal meditation, and body scanning). This study evaluated the relationship between the Big Five personality dimensions (neuroticism, extraversion, openness to experience, conscientiousness, and agreeableness) and use of MBSR techniques both during the intervention and at a 6-month follow-up. The hypothesis was that those with higher levels of openness and agreeableness would be more likely to use the techniques. Methods: Participants were a community sample of 100 older adults who received an 8-week manualized MBSR intervention. Personality was assessed at baseline by using the 60-item NEO Five-Factor Inventory. Use of MBSR techniques was assessed through weekly practice logs during the intervention and a 6-month follow-up survey. Regression analyses were used to examine the association between each personality dimension and each indicator of MBSR use both during and after the intervention. Results: As hypothesized, openness and agreeableness predicted greater use of MBSR both during and after the intervention, while controlling for demographic differences in age, educational level, and sex. Openness was related to use of a variety of MBSR techniques during and after the intervention, while agreeableness was related to use of meditation techniques during the intervention. Mediation analysis suggested that personality explained postintervention MBSR use, both directly and by fostering initial uptake of MBSR during treatment. Conclusions: Personality dimensions accounted for individual differences in the use of MBSR techniques during and 6 months after the intervention. Future studies should consider how mental health practitioners would use these findings to target and tailor MBSR interventions to appeal to broader segments of the population.

Abstract: Recent studies on affective forecasting clarify that the emotional reactions people anticipate often differ markedly from those they actually experience in response to affective stimuli and events. However, core personality differences in affective forecasting have received limited attention, despite their potential relevance to choice behavior. In the present study, 226 college undergraduates rated their anticipated and experienced reactions to the emotionally-evocative event of Valentine’s Day and completed a measure of the Big Five personality traits – neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness – and their facet scales. Neuroticism and extraversion were associated with baseline mood, experienced emotional reactions, and anticipated emotional reactions. The present findings hold implications for the study of individual differences in affective forecasting, personality theory, and interventions research. [Copyright &y& Elsevier]

Gender and personality may individually impact end-of-life care. Men often receive more aggressive treatments than women near death, and personality – particularly openness – may be associated with increased care utilization when it diverges from traditional treatment norms. However, research has not examined the interaction of these variables in a dyadic context. This study examined the dyadic effects of patient gender and caregiver personality on end-of-life care. Using data from the VOICE randomized clinical trial, the present sample consisted of patient-caregiver dyads receiving outpatient care for advanced cancer in Sacramento and Western New York. Analyses assessed whether caregiver personality was associated with gender-based differences in patient chemotherapy or emergency department/inpatient visits in the 30 days before death. Logistic regression examined the interaction between caregivers' Big Five personality dimensions and patient gender while accounting for patient and caregiver demographic and health characteristics. Of a total of 134 patient-caregiver dyads, 19.4% (n = 26) of patients received chemotherapy and 47.8% (n = 64) had an emergency department/inpatient visit in the 30 days before death. Results demonstrated a significant interaction between caregiver openness and patient gender on receipt of chemotherapy (odds ratio = 0.07, p = 0.006). When caregivers were less open, men were more likely to receive chemotherapy near death, whereas when caregivers were more open, women were more likely to receive chemotherapy near death. Results suggest caregiver personality characteristics, particularly openness, might disrupt gender-based treatment norms at end-of-life. Findings demonstrate that patient and caregiver factors can interact to explain patient healthcare utilization. [ABSTRACT FROM AUTHOR]
