The Diagnostic Interview Schedule for Children (DISC-2.1) in Spanish: reliability in a Hispanic population.

The reliability across time, informants and interviewers of the Spanish translation of the DISC-2.1 was tested on a Puerto Rican Hispanic sample using a test-retest design. Levels of reliability between clinic and community samples and between younger and older children were compared to explore the sources of low reliability for certain psychiatric disorders. Parents' reports tended to be more reliable than those of their children, although the difference was less obvious with older children. Reliability was generally higher for the externalizing disorders and when the second interviewer was a psychiatrist rather than a lay interviewer.

The prevalence of women with breast implants in the United States--1989.

Most estimates of the number of women with breast implants appear to be extrapolations of industry or clinical data. While both provide valuable information, the former about the total number of devices ever produced or sold and the latter about the cumulative number of surgeries performed, neither can be used to directly estimate the prevalence of women with silicone gel or saline implants. In 1989, Market Facts, Inc., conducted a mail survey of 40,000 households chosen as representative of the population of the United States and received responses from 70.7%. Overall, the prevalence was 8.08 per 1,000 women with about 60% of the devices reportedly implanted for cosmetic reasons. The procedure was more common among Whites of the higher socio-economic classes. Based upon the results of this survey, the total number of US women in 1989 with breast implants was estimated to be 815,700 (95% confidence interval: 715,757-924,729).

Depressive symptoms and depressive diagnoses in a community population. Use of a new procedure for analysis of psychiatric classification.

A multivariate classification technique was used to examine whether depressive symptoms and symptoms frequently associated with depressive disorders would cluster into recognizable syndromes that parallel traditional DSM-III psychiatric diagnoses. An analysis was made of all respondents in the Epidemiologic Catchment Area (ECA) project of the Piedmont region of North Carolina who reported suffering from depressive symptoms (n = 406) at the second wave of the ECA study. The analysis identified five profiles of symptoms that adequately described the interrelationships of the symptoms as reported in the population. One profile included a set of symptoms nearly identical to the symptoms associated with the DSM-III classification of major depression. Other depressive syndromes emerged and included a premenstrual syndrome among younger women and a mixed anxiety/depression syndrome. The existence of these other depressive syndromes may explain the present discrepancy in the epidemiologic literature between a high prevalence of depressive symptoms and a low prevalence of traditional depressive diagnoses in community populations.

Estimates of the prevalence of childhood maladjustment in a community survey in Puerto Rico. The use of combined measures.

A two-stage epidemiologic survey was carried out on a probability sample of the population aged 4 through 16 years in Puerto Rico. The survey used the Child Behavior Checklist as a screening instrument, and prevalence rates were estimated on the basis of clinical diagnoses and other measures provided by child psychiatrists during the second stage. Maladjustment was operationally defined through the use of combined measures, including DSM-III diagnosis and a scale of functional impairment. Data were provided on the demographic correlates of maladjustment and on the comorbidity of DSM-III diagnostic domains. The prevalence rates obtained vis-à-vis the availability of mental health services on the island reflected a major public health problem.

Malignant melanoma in the elderly.

Advancing age is associated with poorer prognosis in malignant melanoma. We studied 3,872 cases of malignant melanoma to evaluate whether the effect of age could be analyzed relative to sex, tumor depth, primary site, and other clinical and pathologic variables. The sex distribution by age shows a slight female predominance in the early and late decades but male predominance in the middle years. The percentage of patients with metastatic disease at initial diagnosis did not vary with age, despite greater diameter and depth of lesions in the older patients. In fact, in the older age groups, initial nodal metastasis occurred slightly less frequently. Trunk primaries decreased in frequency with increasing age, while extremity lesions remained relatively constant, and face, nose, and ear lesions increased. This was in part related to the histopathologic type, as lentigo maligna lesions increased in frequency with age, superficial spreading lesions were somewhat less frequent in the older age group and nodular types were fairly constant. On the basis of both Clark's level and Breslow thickness, there was an increasing proportion of deeper penetrating lesions in the older age group. The mean diameter of these lesions on the skin surface was also greater for the older patients. This would suggest that lesions in the older individual remain confined to the local site longer, penetrate and spread, but do not necessarily metastasize more rapidly. Cox model regression analysis of survival time within stage showed that age was highly significant as a poor prognostic factor. Though the adverse relation of advancing age with survival was partially explained by predominance of other unfavorable factors, such as primary site, depth of lesion, or histologic type, age remained an independent poor prognostic factor (chi 2 = 5.3; P = .02) for death due to melanoma.

Somatization disorder in a US southern community: use of a new procedure for analysis of medical classification.

The authors examine somatization disorder in a community population, using grade of membership analysis, a new multivariate analytical technique for the analysis of medical classification. The technique is used to examine whether somatic symptoms will cluster into a clinical syndrome resembling somatization disorder, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), if no a priori assumptions are made about the interrelationship of somatic symptoms or their clustering into clinical syndromes. Grade of membership analysis is applied to all respondents in the US National Institute of Mental Health Epidemiological Catchment Area Project of the Piedmont region of North Carolina reporting three or more somatic symptoms from the somatization disorder section of the Diagnostic Interview Schedule. The analysis indicates that seven 'pure' types, roughly analogous to clusters in cluster analysis, best describe the interrelationship of the symptoms included in the analysis. One 'pure' type in the analysis is nearly identical to DSM-III somatization disorder and is associated with demographic characteristics consistently found among patients with DSM-III somatization disorder. The present results demonstrate that symptoms associated with this disorder do cluster in a highly predictable fashion and represent a strong validation of the natural occurrence of an entity resembling somatization disorder.

Psychiatric disorders. A rural/urban comparison.

We studied rural/urban differences in the prevalence of nine psychiatric disorders from a community survey (part of the Epidemiologic Catchment Area Program) of 3,921 adults living in the Piedmont of North Carolina. Crude comparisons disclosed that major depressive episodes and drug abuse and/or dependence were more common in the urban area, whereas alcohol abuse/dependence was more common in the rural area. When prevalence for these disorders was stratified for age, sex, race, and education (factors that may confound urban/rural comparisons), a number of significant differences were identified, such as higher prevalence of major depression in female and white subjects and higher prevalence of alcohol abuse/dependence in the less educated subjects. A logistic-regression analysis was used to determine if significant urban/rural differences persisted when these potential confounders were controlled. Major depressive disorders were found to be twice as frequent in the urban area in this controlled analysis.

A statistical analysis of the classification of depression in a mixed community and clinical sample.

Depressive symptoms in three samples are assessed using grade-of-membership analysis to clarify the distribution of depressive symptoms across traditional affective diagnoses. The technique is used to examine whether depressive symptoms and symptoms frequently associated with depressive disorders cluster into recognizable syndromes or pure types that parallel current operational diagnoses. Three hundred and ninety subjects were studied to address the question: among a mixed population with a range of depressive symptoms, will syndromes resembling endogenous depression and demoralization emerge from the range of presentation of depressive symptoms? A single pure type is nearly identical to the DSM-III classification of major depression with melancholia. No such pure type emerged that resembled demoralization.
