    Depressive symptom clusters and 5-year incidence of coronary artery calcification: the coronary artery risk development in young adults study
    (American Heart Association, 2012) Stewart, Jesse C.; Zielke, Desiree J.; Hawkins, Misty A. W.; Williams, David R.; Carnethon, Mercedes R.; Knox, Sarah S.; Matthews, Karen A.; Psychology, School of Science
    Background: Because depression is a multidimensional construct and few studies have compared the relative importance of its facets in predicting cardiovascular risk, we evaluated the utility of depressive symptom clusters in predicting the 5-year incidence of coronary artery calcification (CAC). Methods and results: Participants were 2171 middle-aged adults (58% female; 43% black) from the Coronary Artery Risk Development in Young Adults (CARDIA) study who were free of cardiovascular disease. Depressive symptom clusters (z scores) were measured by questionnaires in 2000 to 2001, and CAC was measured by electron beam computed tomography in 2000 to 2001 and 2005 to 2006. There were 243 cases (11%) of incident CAC, defined as the absence of CAC at baseline and the presence of CAC at follow-up. Total depressive symptoms (odds ratio, 1.16; 95% confidence interval, 1.02-1.33; P=0.03) and the depressed affect cluster (odds ratio, 1.17; 95% confidence interval, 1.03-1.33; P=0.02) predicted incident CAC; however, the somatic, interpersonal distress, low positive affect, and pessimism clusters did not. The depressed affect-incident CAC relationship was independent of age, sex, race, education, and antidepressant use; was similar across sex and racial groups; and was partially accounted for by tobacco use and mean arterial pressure. Conclusions: In contrast to recent results indicating that the somatic cluster is the most predictive of cardiovascular outcomes, we found that the prospective association between depressive symptoms and incident CAC was driven by the depressed affect cluster. Our findings raise the possibility that there may not be 1 facet of depression that is the most cardiotoxic across all contexts.

    THE PREDICTIVE UTILITY OF ECOLOGICAL MOMENTARY ASSESSMENT MEASURES VERSUS RETROSPECTIVE SELFREPORT MEASURES: A QUALITATIVE LITERATURE REVIEW
    (Office of the Vice Chancellor for Research, 2011-04-08) Zielke, Desiree J.
    Proponents of ecological momentary assessment (EMA), in which repeated measures of variables are obtained in real-time from individuals in their environment, have asserted that the reliability and validity of self-reports obtained by this method are superior to those obtained by traditional retrospective assessments. Because this claim has not been adequately evaluated, we conducted a qualitative literature review to address the following question related to this assertion: Is the predictive utility of EMA self-reports superior to that of retrospective self-reports? We searched MedLine and PsycInfo for studies that obtained both EMA measures and retrospective measures of the same construct and examined the ability of EMA and retrospective measures to predict the same outcome. Eight studies were identified. One study examined two separate outcomes and therefore results are presented based on 9 findings. The studies revealed that EMA measures were stronger predictors of the outcome than retrospective measures in 5 (56%) findings. In 2 (22%) findings, retrospective measures outperformed EMA measures. Results of 2 findings were equivocal. In sum, the bulk of the evidence provides preliminary support for the notion that EMA measures have superior predictive utility as compared to retrospective measures; however, the type of outcome (biological vs. behavioral/subjective) may influence the pattern of results. There is a clear need for research to determine in which situations EMA or retrospective measures are stronger predictors of outcomes.
