Title: A very good scientific guide
Review: As epidemiology and public health professor finally I found an excelent guide for planning and conducted research in the field of human sexuality. From the theory ( Chapter 2) to quantitative data analysis (Chapters 12 and 13), the Handbook of M. Wiederman and B.Whitley Jr. give the basic elements for a scientific research.Only a few critics words from an epidemiological perspective, I'm not agreed with the skeptical wiew about observational (non experimental) studies. The theoretical and empirical developement of epidemiology is a valid investigation way in human sexuality. Case-control,cohort studies, confounding bias control and interaction analisys are tools for a non interventional research, that avoid problems of internal validity, the serious troubles and artificiality of experimental approach.
