    Agreement between older adult patient and caregiver proxy symptom reports
    (Springer, 2022-05-14) Kroenke, Kurt; Stump, Timothy E.; Monahan, Patrick O.; Medicine, School of Medicine
    Background: Proxy report is essential for patients unable to complete patient-reported outcome (PRO) measures themselves and potentially beneficial when the caregiver perspective can complement patient report. In this study, we examine agreement between self-report by older adults and proxy report by their caregivers when completing PROs for pain, anxiety, depression, and other symptoms/impairments. Methods: Four PROs were administered by telephone to older adults and their caregivers followed by re-administration within 24 h in a random subgroup. The PROs included the PHQ-9 depression, GAD-7 anxiety, PEG pain, and SymTrak multi-dimensional symptom and functional status scales. Results: The sample consisted of 576 older adult and caregiver participants (188 patient-caregiver dyads, 200 patients without identified caregiver). The four measures had good internal (Cronbach's alpha, 0.76 to 0.92) and test-retest (ICC, 0.63 to 0.92) reliability whether completed by patients or caregivers. Total score and item-level means were relatively similar for both patient and caregiver reports. Agreement for total score as measured by intraclass correlation coefficient (ICC) was better for SymTrak-23 (0.48) and pain (0.58) than for anxiety (0.28) and depression (0.25). Multinomial modeling showed higher (worse) patient-reported scale scores were associated with caregiver underreporting, whereas higher caregiver task difficulty was associated with overreporting. Conclusion: When averaged over individuals at the group level, proxy reports of PRO scores by caregivers tend to approximate patient reports. For individual patients, proxy report should be interpreted more cautiously for psychological symptoms as well as when patient-reported symptoms are more severe, or caregiver task difficulty is high.

    The Association between Relationship Satisfaction Concordance and Breast Cancer Survivors’ Physical and Psychosocial Well-Being
    (MDPI, 2024-01-08) Vachon, Eric A.; Krueger, Ellen; Haggstrom, David A.; Champion, Victoria L.; School of Nursing
    The purpose of this article is to examine the association of relationship satisfaction concordance between breast cancer survivors (BCSs) and their partners with matched controls on physical and psychosocial outcomes. Dyads of BCSs, age-matched controls, and partners were recruited as part of a larger, cross-sectional QOL survey study. Relationship concordance was measured by the ENRICH marital satisfaction score, with each dyad's score equaling the absolute value of the difference in satisfaction between survivor/control and their partner (lower score = greater concordance). Dependent variables for survivors/controls were social constraint, physical function, depression, fatigue, attention function, and sleep disturbance. Relationship satisfaction and concordance were used as the primary independent variables, while controlling for dyad category, race, education, income, and age within multiple linear regression models. The sample consisted of 387 dyads (220 BCSs, 167 controls). Relationship satisfaction concordance ranged from 0 to 53.4 (mean = 10.2). The BCS dyads had significantly worse concordance (11.1) than the controls (9.1) (p = 0.050). Within the multiple regression models, lower concordance was significantly associated with increased social constraint (p = 0.029), increased depression (p = 0.038), and increased fatigue (p = 0.006). Poor relationship satisfaction and concordance were significantly associated with poor physical and psychosocial outcomes. The maintenance of relationships should remain a focus through difficulties of cancer and into survivorship for survivors, partners, and providers.
