“…These data included self-report, parent rating, and peer nomination measures of depression collected on 882 young adolescents over four waves that were 6 months apart. The self-report was the Children's Depression Inventory (CDI; Kovacs, 1985); parent ratings derived from a parent version of the CDI (Wierzbicki, 1987); and peers provided information using the Peer Nomination Index of Depression (PNID; Lefkowitz & Tesiny, 1980). The sample contained 452 boys (51%) and 430 girls (49%).…”

Coping with longitudinal data in research on developmental psychopathology

Like many developmental psychopathology researchers, I began my career wishing I had longitudinal data. With longitudinal data, I felt I would be one step closer to identifying the predictors, and perhaps the causes, of childhood psychopathology. At the very least, I would no longer be obliged, at the end of every paper, to issue the standard apology for having derived all my conclusions from cross-sectional studies. Now, fortunate enough to have accumulated longitudinal data, I spend much of my time coping with their incumbent frustrations. In this article, I have two primary goals. One is to outline some of the problems often associated with the analysis of longitudinal data. The second is to suggest some methodological and statistical approaches that might be helpful in coping with these problems. In this effort, I use examples drawn from my work on depression in children; however, the general points should be relevant to other areas of developmental psychopathology as well.Underlying many longitudinal data analytic problems is the stability of the construct of interest. Throughout this article, I use the term stability to mean the constancy of individual differences over time. According to this definition, high stability suggests that individuals who score high on a construct (relative to their peers) at one point in time continue to score high (relative to their peers) at subsequent points in time. Conversely, individuals who score low (relative to their peers) continue to score low. I do not use the term to refer to the constancy of an individual's scores relative to his or her self over time. Thus complete and perfect stability can exist despite the fact that every individual's score changes over time, as long as all of these changes occur in the same direction and to the same extent (Nesselroade, 1988(Nesselroade, , 1991.In psychopathology research, measures of disorders often show rather high levels of stability over time, a phenomenon that becomes problematic when one attempts to predict or explain change in such measures. Predicting change in a highly stable phenomenon can be frustrating (if not pointless). The problem becomes evident in the classic regression approach to non-experimental, longitudinal data. Let us imagine a study in which the investigator hypothesizes that stressful life events at time 1 (represented by S 1 ) generate or predict depression at time 2 (D 2 ). The investigator wants to control (statistically) for prior levels of depression (D 1 ). A regression approach to this problem would be symbolized as D 2 = β 0 + β 1 D 1 + β 2 S 1 , in which the size and significance of β 2 would be taken as support for the hypothesis. A problem emerges when D is highly stable. As the correlation between D 1 and D 2 increases, D 1 explains more and more of the variance in D 2 (i.e., β 1 gets quite large), leaving less variance for S 1 to explain (i.e., β 2 becomes quite small). For example, if depression has a stability of .5, the range of possible values for β 2 extends from 0 to as high as .75. I...

“…The CDI-parent takes approximately 10 minutes to complete, and items are presented on a 4 point Likert scale. The psychometric properties of this test are good as indicated by strong correlations between the CDI-parent and both the children's and teacher's version of this instrument (Wierzbicki, 1987).…”

“…It would be interesting to determine whether a parental measure that specifically assesses depression instead of a broad band questionnaire would improve the predictive ability. Research on the English version of the parent version of the CDI (CDI-P) resulted in a high degree of internal consistency, good test-retest reliability, and a moderately high degree of convergent validity (Cole, Truglio, & Peeke, 1997;Kazdin, French, Unis, & Esveldt-Dawson, 1983;Wierzbicki, 1987). In future research it might be interesting to further investigate the role of parent reports.…”

Introduction. In order to set up an effective early-detection of depressive symptoms in youngsters, the current study aims to investigate whether two measure moments of the Children's Depression Inventory (CDI) improve screening and whether a multi-informant procedure is superior compared to a single-informant procedure thereby controlling for comorbid symptoms. Method. Youngsters (10-15 years) filled in the CDI and an Anxiety Scale at Time 1 and the CDI and Youth Self Report one week later. Next, a structured clinical interview was administered. The Child Behaviour CheckList was filled in by the parents. Results. Two measure moments of the CDI are not more accurate in capturing disordered mood changes. Furthermore, parent reports were no significant contributor to the variance over and above the CDI. Discussion. A second moment does not increase screening accuracy. Further research on setting up an effective multistage screening procedure for depressive symptoms for youngsters is however necessary.
