    Differential Relationships of Hope and Optimism with Adjustment in Breast Cancer Patients
    (2012-03-20) Rock, Emily E.; Rand, Kevin L.; Stewart, Jesse C.; McGrew, John H., 1953-
    Psychological and marital adjustment are two important outcomes for patients with breast cancer. Personality traits, such as hope and optimism, may influence adjustment to adversity. It was hypothesized that patient and partner hope and optimism would differentially predict patient marital and psychological adjustment. Measured variable path analysis with 56 patient-partner dyads found that patient and partner hope equally predict patient marital adjustment, while there was a trend for patient optimism predicting patient psychological adjustment. These results suggest that hope and optimism differentially predict adjustment outcomes, and that the partner also has a role in the patients’ adjustment. Regression analyses were used to examine the hypothesis that discrepancies in patient and partner personality would result in maladjustment. No interaction effects were found predicting patient psychological adjustment. Three out of six interactions were found for patient marital adjustment. These analyses suggest that complementary personality styles among couples coping with breast cancer may result in optimal patient marital adjustment.

    Dyadic influence of hope and optimism on patient marital satisfaction among couples with advanced breast cancer
    (Springer, 2014-09) Rock, Emily E.; Steiner, Jennifer L.; Rand, Kevin L.; Bigatti, Silvia M.; Department of Psychology, School of Science
    PURPOSE: An estimated 10-40 % of breast cancer (BC) patients report negative changes to their partnered relationships. Literature suggests that for these patients, marital satisfaction is related to depression and other quality of life factors which are associated with survivorship and treatment response. However, existing literature does not provide a clear explanation of the factors that strengthen vs. create strain in couples facing cancer. Given the benefits of a satisfying relationship to patient quality of life, it is important to better understand factors that put patients at greater risk for marital difficulties. This study examined the differential and combined roles of hope and optimism among BC patients and their partners on patient marital satisfaction. METHOD: Fifty-six breast cancer patient-partner dyads completed study questionnaires as part of a larger study. Regression analyses were used to examine the main and interaction effects of patient and partner hope and optimism on patient marital satisfaction. RESULTS AND CONCLUSION: Higher patient and partner hope predicted greater patient marital satisfaction, whereas optimism did not. These results are divergent from the literature on optimism and well-being, which shows the importance of studying these two traits concurrently. Interaction effects suggest certain combinations of patient and partner hope and optimism are more beneficial than others for patient marital satisfaction and suggest a dyadic approach is important for investigation of well-being in breast cancer.

    Everyone Wants An "A": The Role of Academic Expectations in Academic Performance
    (2019-08) Fortney, Sarah Katherine; Rand, Kevin L.; Cyders, Melissa; Stewart, Jesse C.
    Expectations are a key aspect of human success and behavior that predict outcomes in a variety of settings, including academics. Trait expectations (e.g., hope and optimism) and previous experiences appear relevant to the formation of specific expectations. Specific expectations predict outcomes, with positive expectations predicting better outcomes. In academics, positive specific expectations predict improved academic performance; however, there are aspects of this relationship that are unclear. This study sought to examine the formation of specific academic expectations and the relationship between these expectations and academic performance. The current study aimed to replicate previous research about the unique influences of academic expectations, expand this knowledge by examining possible mechanisms of the relationship between academic expectations and academic performance, and test how previous academic experience affected this relationship. Results of this study showed that previous GPA and optimism, but not hope, predicted academic expectations. Academic expectations predicted academic performance, but this relationship was not mediated by study time or stress. Finally, previous GPA moderated the relationship between academic expectations and academic performance, such that the positive association between academic expectations and academic performance was stronger for those with poorer prior performance.

    Hope, optimism, and hopelessness : conceptual distinctions and empirical associations with suicidal ideation
    (2018-12) Shanahan, Mackenzie Lynmarie; Rand, Kevin L.; Hirsh, Adam T.; Stewart, Jesse C.
    Trait expectancies are related to several aspects of psychological well-being. Specifically, hope, optimism, and hopelessness have been associated with positive and negative indicators of mental health, including suicidality. In addition to empirical similarities, these constructs also have substantial conceptual and measurement overlap. Moreover, while current literature suggests hope and optimism are unique constructs, the distinctions between hopelessness, hope, and optimism remain unclear. The main goals of the present study were: 1) to identify the best structural conceptualization of hope, optimism, and hopelessness; and 2) to apply this conceptualization to examine how different trait expectancies uniquely predict suicidal ideation. Undergraduate students (N= 456) completed a battery of questionnaires at two time points, two months apart. To achieve the first goal, a series of a priori factor models of hope, optimism, and hopelessness was tested using confirmatory factor analysis (CFA). CFA was also performed to confirm the best factor structure of suicidal ideation. Finally, using results from these CFAs, the differential relationships between trait expectancies and suicidal ideation were examined using latent variable path analysis. Results showed that hope, optimism, and hopelessness are best conceptualized as distinct but related constructs. Results also found that both hope and hopelessness predicted increased suicidal ideation over time; whereas, optimism was not predictive of suicidal ideation. Surprisingly, these results suggest that higher hope may be a risk factor for increased suicidal ideation among undergraduates.

    Intensive Treatment Near the End of Life in Advanced Cancer Patients
    (2016-04-07) Touza, Kaitlin Kyna; Rand, Kevin L.; Stewart, Jesse; Mosher, Catherine Esther; Grahame, Nicholas J.
    Many advanced cancer patients receive intensive treatment near the end of life (EOL). Intensive treatment near the EOL is often associated with worse outcomes, such as worse quality of life (QOL), greater distress in patients and caregivers, and higher health care costs. For cancers typically unresponsive to chemotherapy such as lung and gastro-intestinal (GI), the side effects of intensive treatment are endured without increasing survival time. To date, research on EOL care in advanced cancer patients has focused on patient prognostic understanding, physician communication, and patient distress. These factors do not fully explain why many patients receive intensive treatment near the EOL when there is no hope for cure. Hence, there is a need to better understand the factors that influence EOL treatment in order to improve patient and caregiver outcomes. Self-Regulation Theory (SRT) provides a framework that may help explain motivations and care decisions in this population. This study had two aims: 1) to examine the associations between EOL clinical encounters (i.e., EOL conversations with a physician) and treatment intensity in advanced cancer patients near the EOL; and 2) to examine the associations between important SRT constructs (i.e., goal flexibility, hope, and optimism) and treatment intensity in advanced cancer patients near the EOL. A sample of 76 advanced lung and GI cancer patients was recruited from Indiana University Simon Cancer Center. Hope predicted receiving chemotherapy closer to death (β = -.41, t (66) = -2.31, p = .025), indicating more intensive treatment near EOL. Other predictor variables were not significantly associated with intensive treatment. Implications and methodological limitations are discussed.

    Optimism and cardiovascular health: Longitudinal findings from the CARDIA Study
    (Wolters Kluwer, 2020) Boehm, Julia K.; Qureshi, Farah; Chen, Ying; Soo, Jackie; Umukoro, Peter; Hernandez, Rosalba; Lloyd-Jones, Donald; Kubzansky, Laura D.; Medicine, School of Medicine
    Objective: Favorable cardiovascular health is associated with greater longevity free of cardiovascular disease. Although the prevalence of cardiovascular health decreases with age, less is known about protective factors that promote and preserve it over time. We investigated whether optimism was associated with better cardiovascular health over a 10-year period. Methods: Participants included 3188 Black and White men and women from the Coronary Artery Risk Development in Young Adults study. Self-reported optimism was assessed in 2000 (this study's baseline) with the revised Life Orientation Test. Favorable cardiovascular health was defined by healthy status on five components of cardiovascular functioning that were repeatedly assessed through 2010 either clinically or via self-report (blood pressure, lipids, body mass index, diabetes, and smoking status). Linear mixed-effects models examined whether optimism predicted cardiovascular health over time, adjusting for covariates such as sociodemographic characteristics, health behaviors, health status, and depression diagnosis. Results: In models adjusting for sociodemographic characteristics, optimism was associated with better cardiovascular health across all time points (β = 0.08, 95% confidence interval = 0.04-0.11, p ≤ .001) but not with rate of change in cardiovascular health. Findings were similar when adjusting for additional covariates. Optimism did not interact significantly with race (p = .85) but did with sex, such that associations seemed stronger for women than for men (p = .03). Conclusions: Optimism may contribute to establishing future patterns of cardiovascular health in adulthood, but other factors may be more strongly related to how slowly or quickly cardiovascular health deteriorates over time.

    The Role of Trait and Specific Expectations in the Dysmenorrhea Experience
    (2024-08) Rogers, Sarah K.; Rand, Kevin L.; Mosher, Catherine E.; Stewart, Jesse C.; Chen, Chen X.
    Dysmenorrhea is the most common pain condition in reproductive-aged women and is characterized by pain during menstruation. Dysmenorrhea has far-reaching effects, such as increased psychological distress, increased relationship problems, reduced physical activity, and decreased sleep efficiency. It is the leading cause of absenteeism in this population. Though dysmenorrhea impacts many women and has such far-reaching effects, it has not been studied as extensively as other pain conditions, specifically regarding trait expectations and specific expectations. In other pain conditions, hope and optimism, the two most studied trait expectations, are protective factors for pain severity, interference, and the psychological effects of pain. Trait expectations additionally predict specific expectations, with hope predicting specific expectations related to the self, and optimism predicting specific expectations related to experiences. Both self- and experience-expectations predict outcomes, such as pain severity and pain tolerance. The current study sought to 1) examine the factor structure of specific expectations for dysmenorrhea; 2) examine the roles of trait and specific expectations in predicting dysmenorrhea; and 3) examine the roles of trait expectations and dysmenorrhea in predicting psychological adjustment. A longitudinal study of 389 menstruating women, over the age of 18, who could read and write English was conducted through CloudResearch. Confirmatory factor analysis and mixed latent- and measured-variable path analysis were used. Results indicated two distinct factors of specific expectations, pain-expectation and self- expectation. Hope predicted self-expectation, which predicted dysmenorrhea interference. Pain- expectation predicted dysmenorrhea severity and interference. Additionally, both hope and optimism predicted psychological adjustment. Dysmenorrhea interference predicted psychological distress. However, trait expectations did not predict dysmenorrhea. This study is the first to examine the associations among trait expectations, specific expectations, and dysmenorrhea and expands on the differences between dysmenorrhea and other pain conditions.

    Searching for Meaning in Life: The Moderating Roles of Hope and Optimism
    (2018-09) Fischer, Ian Charles; Rand, Kevin L.; Hirsh, Adam T.; Stewart, Jesse C.
    While research links the presence of meaning in life to better psychological well-being, the relationship between the search for meaning and psychological well-being is less clear. The search for meaning is generally thought to be psychologically distressing, but there is evidence that this process is moderated by the presence of meaning in life. Because the search for meaning in life can be considered a goal pursuit, goal-related personality traits may also moderate the relationship between the search for meaning and psychological well-being. The first aim of this cross-sectional study was to replicate the moderating effect of the presence of meaning on the relationship between the search for meaning and psychological well-being in a sample of undergraduates (N = 246). The second aim was to examine the potential moderating effects of hope and optimism on these relationships. As an exploratory third aim, this study examined whether there was a unique combination of the presence of meaning, the search for meaning, and hope or optimism that differentially predicted psychological well-being. Results suggest that optimism and the presence of meaning, but not hope, are significant moderators of the relationship between the search for meaning and psychological well-being. Implications and limitations of these findings are discussed.
