Biological and Psychological Manifestations of Religion Supplement for Psycholsocial Manifestations of Religion Substudy ( 6/2009 - 7/2009 )
Our parent study has two arms: (a) A 20-page questionnaire returned in 2006 by 10,988 Seventh-day Adventist assessing early, lifetime, and current stress, discrimination, and trauma history, many varieties of religious belief and experience, multiple possible mediating pathways, and quality of life; (b) A subsample of 508 who in 2007 completed the 20-page questionnaire and attended a clinic where a variety of biometric, biologic, cognitive, and performance measures were collected to assess allostatic load. The second wave of measurement begins fall 2009 for the questionnaire and 2010 for the clinic. This supplement request deals only with the questionnaire study. Our original plan was to send questionnaires to a random sample of 4,500 from the 10,988 in hopes of 3,000 being returned. Now we propose sending questionnaires to all 10,988 in hopes getting back 7,300 completed questionnaires. Our rationale: (a) some analysis subgroups would be too small for adequate power if we only had an N of 3000; (b) for possible longer term studies beyond the lifetime of this grant, we need as many as possible to counter some of the effects of attrition; (c) some events of interest, e.g. new divorce, are of low incidence (123 per 1000 in the last year in our mean age 63 sample) and we would not have sufficient cases occurring between 2006 and 2009 for strong analysis with only 3,000; the recent economic downturn provides an opportunity to study the effects of job and/or income loss but the incidence of these problems is unknown and could be low in our well educated sample. Thus, a larger sample makes it more likely that we will be able to study this. All of our national consultants have urged us to expand our sample. Additionally, our data set is strong for the study of Black-White health disparities as we over sampled Blacks (n = 3,754 vs. 6,534 Whites). To accelerate and increase the excellence of our work in these areas, we propose: adding additional senior consultants with expertise in the area of health disparities; increasing time commitment of a junior investigator in this area and providing him with additional mentoring; adding two half-time doctoral students, each charged to write a paper aided by mentors) in the health disparities and religion area; and increasing statistical and secretarial support.
