    Expectancy in Pelvic Organ Prolapse Surgery and Recovery: Factor Structure and Validity
    (2019-08) Touza, Kaitlin Kyna; Rand, Kevin L.; Mosher, Catherine E.; Hirsh, Adam T.; Williams, Jane R.
    Women describe pelvic organ prolapse (POP) surgery as difficult to recover from. Expectancy is related to recovery in other surgeries but has not been examined in POP. There is no established measure of surgery expectancy or utility in women with POP. This research had four aims: 1) to establish the factor structure of a new measure of POP surgery expectancy; 2) to establish predictive validity of the expectancy measure by examining its ability to predict self-rated recovery over time; 3) to establish concurrent validity of the expectancy measure; and 4) to examine the ability of utility to predict additional variance in recovery. Exploratory factor analysis revealed a three-factor solution. Factors are conceptualized as: 1) Bladder/Bowel Function; 2) Sexual Function; and 3) Physical Function. Bladder/Bowel Function correlated with optimism and self-efficacy (r = .17, p = .03 and r = .27, p = .00, respectively). Physical Function was predictive of recovery at 42 days (standardized coefficient = .25; p < .05). However, these factors were generally poor and inconsistent predictors of recovery. Utility did not predict additional variance in recovery. Potential explanations for the poor predictive ability of the measure are discussed. The development of a measure that amends these limitations may still be beneficial. Further, exploring and establishing the relationship between surgery expectancy, utility, and recovery may guide physician-patient discussions and lead to improved surgical outcomes.

    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.
