Article Personal characteristics associated with the effect of childhood trauma on health John Muench 1 , Sheldon Levy 1 , Rebecca Rdesinski 1 , Rebekah Schiefer 1 , Kristin Gilbert 1 , and Joan Fleishman 1 Abstract Objective: This article will describe a pilot study to explore associations between adult attachment style, resilience, Adverse Childhood Experiences, and adult health. Method: A self-report survey was mailed to 180 randomly selected primary care patients and linked to a retrospective chart review. The patients met the following criteria: (1) enrolled for at least the previous year at their primary care clinic, (2) 21 years of age or greater, (3) English as their primary language, and (4) were seen by their provider on selected dates of the study. The survey was made up of three instruments: (1) the Adverse Childhood Experiences Questionnaire which consists of 10 questions about the respondent’s adverse experiences during their first 18 years of life; (2) the Relationship Scales Questionnaire which measures adult attachment style; and (3) the Connor–Davidson Resilience Scale, a self-report scale that measures individual’s perceptions of their resilience. For each returned questionnaire, we calculated a measure of medical complexity using the Elixhauser Comorbidity Index. Results: Of the 180 randomly selected patients from four clinic sites, 84 (46.6%) returned completed questionnaires. We found that Adverse Childhood Experience scores were significantly correlated with health and attachment style and trended toward association with resilience. 1 Department of Family Medicine, Oregon Health & Science University, Portland, OR, USA Corresponding Author: John Muench, Department of Family Medicine, Oregon Health & Science University, Portland, OR, USA.
