“…An example of a successful endeavour to generalise this experience is the study of De Groot and Mezzich on the issues of psychiatric statistics published as a chapter in the special International Statistical Institute Centenary Volume. 2 This review had been used at one time for analysis of the application of statistical methods in the Soviet psychiatric literature of the 1980's. 1 The present study had been undertaken with a view to proceed with comparing the Russian experience in psychiatric statistics with the international one and to follow up dynamics of both during the period 'bf 10 yeai:s. However, this journal was not appropriate for the subsequent (1990) comparative assessment since it's character had changed considerably owing to predominance of neurological subjects.…”

A comparative study was carried out to determine the trend in the use of statistical methods in the papers published in the leading Russian, American and British psychiatric journals of the 1980 -90 -ies. Within 10 years the quota of papers with statistic s increased considerably in the American and British journals (from 58.6% to 67.6%), especially in the Archives of General Psychiatry (88%). Qualitative changes were notable as well, tending towards the use of nonordinary innovative methods, As regards the Russian psychiatric papers the use of statistical methods was a rare occurrence (21.8% in 1980s), that never changed within 10 years.

“…Another possibility is that inconsistent findings may be due to changes that have happened in both statistical theory and practice as computer hardware and software were being developed (Altman, 1991; Hand & Sham, 1995). Occasionally, these issues have been examined by evaluating statistical errors (White, 1979), statistical contents (De Groot & Mezzich, 1985; McGuigan, 1995; Nieminen, 1995), the use of statistical techniques (Everitt & Landau, 1998; Hokanson et al, 1986) or even the role of statisticians generally (Hand & Sham, 1995; Pocock, 1980) from published psychiatric articles. However, nobody seems to have explored the use of statistical methods and the characteristics of the data from published suicide seasonality studies.…”

The effect of seasons on suicides has been suggested repeatedly. In order to reveal a true seasonal pattern, an appropriate statistical technique, which is sensitive to a specific type of cyclic variation in the data, must be chosen. This study is a review of the use of statistical techniques for seasonality and of some important characteristics of study samples that were evaluated from 46 original suicide seasonality articles published in major psychiatric journals. The results showed that statistical techniques were applied in a majority of articles, but they were commonly lacking regarding analyses, which compared seasonal patterns among subgroups of a population. In recent studies more sophisticated statistical techniques were utilized for seasonality, like spectral analyses, as compared with earlier studies, in which the emphasis was on chi-square tests. Lack of reporting essential features of the data, such as the sample size and monthly values of suicides, were frequent. The calendar effect was adjusted only in 11 studies. Some recommendations concerning the methodological and reporting issues are summarized for future articles on the seasonal affect on suicides.

Psychiatry is the medical speciality that deals with mental disorders. In early medieval times, beating, incarceration, and restraint were the “treatments” endured by the majority of the mentally ill, and a more enlightened perspective has evolved only slowly over the intervening 600 years. In the twentieth century, psychiatry struggled to attain scientific respectability by making quantitative observations on mentally ill patients, and subjecting these observations to a variety of statistical methodology ranging from simple descriptive techniques to complex multivariate analyses.
