Defining and explaining race effects.

Research concepts cannot be materialized until and unless study variables are carefully selected and clearly defined. However, emphasis on variables is not limited to data collection. It should be envisioned from the start that the contents of the variables recorded are congruent with the statistical analysis suggested. These two processes require a comprehensive understanding of variables in epidemiology and biostatistics disciplines. In this article classifications are discussed keeping in view their utility in medical research.

Epidemiological research in mental disorders: lessons for the next decade of research--the NAPE Lecture 1999. Nordic Association for Psychiatric Epidemiology.

OBJECTIVE: To provide an overview of the progress in the field of epidemiology of mental disorders during the last decade, and to discuss challenges for the future. METHOD: Following a review of the achievements of psychiatric epidemiology, current shortcomings in the research and publications in the field are discussed. Suggestions for changes in research and solutions to current deficits are proposed. RESULTS: Future research needs to cover a broader spectrum of psychopathology, including inquiries into sub-threshold characterizations; explore etiopathogenic processes and pathways including genetic, neuroscientific and psychological factors for the onset and persistence of psychopathology; and provide a better assessment of help-seeking behaviors and service utilization. CONCLUSION: Future epidemiological research should strengthen the emerging collaborative links with the neurosciences, clinical research and public health by acknowledging the full range of available epidemiological designs and methods, beyond the current emphasis on large-scale, cross-sectional general population studies.
