Is the diagnostic validity of the various disorders simply lacking empirical data for full substantiation, or does the overall conceptualization of the category have more fundamental problems, not reflecting the \u201ctrue\u201d nature of the phenomena? This paper argues the latter hypothesis. I review the historical development of the classification of PDD, summarize recent empirical data on issues of reliability and validity, and suggest a new approach to classification and understanding.<\/jats:p>\n
