A B S T R A C T PurposeTo assess the comprehension of common medical terms used in prostate cancer in patient education materials to obtain informed consent, and to measure outcomes after prostate cancer treatment. We address this issue among underserved, African-American men because of the increased cancer incidence and mortality observed in this population. Patients and MethodsWe reviewed patient education materials and prostate-specific quality-of-life instruments to identify technical terms describing sexual, urinary, and bowel function. Understanding of these terms was assessed in face-to-face interviews of 105, mostly African-American men, age Ն 40, from two low-income clinics. Comprehension was evaluated using semiqualitative methods coded by two independent investigators. Demographics were collected and literacy was measured. ResultsFewer than 50% of patients understood the terms "erection" or "impotent." Only 5% of patients understood the term "incontinence" and 25% understood the term "bowel habits." More patients recognized word roots than related terms or compound words (eg, "rectum" v "rectal urgency," "intercourse" v "vaginal intercourse"). Comprehension of terms from all domains was statistically significantly correlated with reading level (P Ͻ .001). Median literacy level was fourth to sixth grade. Prostate cancer knowledge was poor. Many patients had difficulty locating key anatomic structures. ConclusionLimited comprehension of prostate cancer terms and low literacy create barriers to obtaining informed consent for treatment and to measuring prostate cancer outcomes accurately in our study population. In addition, the level of prostate cancer knowledge was poor. These results highlight the need for prostate cancer education efforts and outcomes measurements that consider literacy and use nonmedical language.
We conducted a community based, randomized control trial of Promoting First Relationships (PFR; Kelly, Sandoval, Zuckerman, & Buehlman, 2008) to improve parenting and toddler outcomes for toddlers in state dependency. Toddlers (10 – 24 months; N = 210) with a recent placement disruption were randomized to 10-week PFR or a comparison condition. Community agency providers were trained to use PFR in the intervention for caregivers. From baseline to post-intervention follow-up, observational ratings of caregiver sensitivity improved more in the PFR condition than in the comparison condition, with an effect size for the difference in adjusted means post-intervention of d = .41. Caregiver understanding of toddlers’ social emotional needs and caregiver reports of child competence also differed by intervention condition post-intervention (d = .36 and d = .42) with caregivers in the PFR condition reporting more understanding of toddlers and child competence. Models of PFR effects on within-individual change were significant for caregiver sensitivity and understanding of toddlers. At the 6-month follow-up 61% of original sample dyads were still intact and there were no significant differences on caregiver or child outcomes, although caregivers in the PFR group did report marginally (p<.10) fewer child sleep problems (d = −.34).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
