We applied a computationally practical form of probit analysis for multiple response variables to data on early childhood development of four psychiatric disorders: disruptive disorders (DD-attention deficit disorders, oppositional defiant disorder, conduct disorder); adjustment disorders (ADJ); emotional disorders (ED-all anxiety disorders, depression); and other DSM-III-R Axis I disorders (OTHER). In addition to estimating the intercept slope and higher order polynomial terms for each age versus diagnosis regression, we estimated simultaneously the correlation among the four diagnostic categories. We then took into account the correlation found among these four diagnostic categories when testing the hypothesis of no age effect, which would have been ignored in a piecemeal univariate approach. Regression lines for diagnostic prevalence indicate a linear increase for OTHER disorders, and a curvilinear increase for ED. We then used expected frequencies of individual response patterns (that is, the 2(4) = 16 possible diagnostic combinations) in obtaining more precise estimates of diagnostic comorbidity and its relation to age. We further generalize the Bock and Gibbons model to alternative specification of the random-effects distribution (that is, they assumed multivariate normality), illustrate how one can estimate the random-effects distribution empirically, and study the robustness of parameter estimates to specification of the random-effects distribution.
While several surveys have shown that psychiatric disorders are common in non-psychiatric hospital departments, information on the course of psychiatric morbidity during the hospital stay is still lacking. Therefore, in two medical hospital departments in Austria we investigated the course of illness in 265 patients staying in the hospital for more than four weeks. Patients were interviewed using the Clinical Interview Schedule. At admission, prevalence of all psychiatric disorders was 46.0%. During the four weeks after admission, mentally well were discharged from hospital more frequently than mentally ill. Among those staying in the hospital after four weeks, prevalence was 51.4%. In the intervening period, the incidence (9.5%) was slightly lower than the rate of remission (12.4%). At both assessments, organic mental illness was the most frequent diagnosis followed by neurotic and adjustment disorders. Thus, in spite of the slightly higher rate of remission than incidence, the overall psychiatric prevalence increased during the first four weeks after admission because of the earlier discharges of the mentally well. In conclusion, our results show that point-prevalence surveys not regarding disease course give an incomplete impression of psychiatric morbidity in non-psychiatric hospital departments.
BACKGROUND: The authors examined recent changes in the number and proportion of patients prescribed antidepressants by psychiatrists in outpatient private practice and characterized antidepressant prescription patterns by patient age, sex, race, payment source, and clinical diagnosis. METHODS: The authors analyzed physician-reported data from the 1985 and 1993-1994 National Ambulatory Medical Care Survey, focusing on visits to physicians specializing in psychiatry. Logistic regressions were used to examine associations between survey year and antidepressant prescription, adjusting for the presence of other variables. RESULTS: The proportion of outpatient psychiatric visits in which an antidepressant was prescribed increased from 23.1% (95% confidence interval [CI], 19.7%-26.5%) in 1985 to 48.6% (95% CI, 47.5%-49.7%) in 1993-1994. After controlling for several patient variables, psychiatric patients were approximately 2.3 (95% CI, 1.8-2.9) times more likely to receive an antidepressant in 1993-1994 than in 1985. In 1993-1994, selective serotonin reuptake inhibitors accounted for approximately half of the psychiatric visits with an antidepressant prescription. Increases in the rate of antidepressant prescription were particularly evident for children and young adults; whites; new patients; and patients with adjustment disorders, personality disorders, depression not otherwise specified or dysthymia, and some anxiety disorders. CONCLUSIONS: During the late 1980s and early 1990s, there was a significant increase in the prescription of antidepressants by office-based psychiatrists. This increase was greatest for patients with less severe psychiatric disorders.
