AbstractThe purposes of this study were to determine if there were differences in pain intensity scores, pain duration scores, mood states, and quality of life of oncology outpatients whose pain intensity scores were congruent with their family caregivers compared to patients whose pain intensity scores were non-congruent and to determine if there were differences in mood states, health status, and caregiver strain between family caregivers whose pain intensity scores were congruent with their family members and those family caregivers whose pain intensity scores were non-congruent. A total of 78 patient-caregiver dyads participated in the study. Patients completed a Demographic Questionnaire, a Cancer Pain Questionnaire, the Profile of Mood States, and the Multidimensional Quality of Life Scale-Cancer 2. Family caregivers completed a demographic questionnaire, the Profile of Mood States, the Caregiver Strain Index, and the Medical Outcome Study Short-Form Health Survey. Both patients and family caregivers rated the patient's pain intensity using a visual analogue scale (VAS). Patients in the non-congruent dyads (i.e. difference of >10 on the VAS score) had significantly more mood disturbance and a poorer quality of life than patients in the congruent dyads. Family caregivers in the non-congruent dyads had significantly higher caregiver strain score than caregivers in the congruent dyads. These findings suggest that differences in the perception of the pain experience between patients and their family caregivers is associated with deleterious outcomes for the patient and their family caregivers.
