The study addresses the characteristics potentially predictive of non-response to a health survey among 2500 24-year-old males, on whom a notable amount of other data was available. The overall non-response rate was 40%, part of which was due to the unreachability of some subjects: 4% of the questionnaires were returned because of unknown addresses. Some (n = 39) of the respondents had concealed the identification number in the questionnaire, which made it impossible to link these data to those collected before in their cases. We were therefore able to use effectively the data on 1450 (58%) responding subjects in this paper. Failure to respond was more common among the subjects who had lived in towns in their youth, had not grown up in a complete family, whose socioeconomic status of the family was unknown, and whose mother was young and had a low educational level. Poorer-than-average school performance at elementary school was also predictive of a high non-response rate. Non-response was heavily associated with previous non-response to a health inquiry. Some aspects of health and behaviour in adolescense, such as smoking at the age of 14, were related to non-response to this survey, too. The non-response was higher than average among those subjects who had suffered from mental disorders (serious mental disorders, less serious mental disorders such as neurotic disorders, adjustment reactions, and psychosomatic disorders and mental retardation). The young men who were employed, were students or were doing military service at the age 24 responded better than those who were unemployed or at disability pension.

The Lundby Study is a prospective, psychiatric-epidemiological study of a normal population that has been repeatedly examined over a period of 25 years. Experienced psychiatrists made home visits and collected the basic information through personal examinations adding supplementary data from other relevant sources. The present book contains point prevalence data of mental disorders such as neuroses, psychoses, organic brain syndromes, psychosomatic disorders, psychopathy, mental retardation, alcoholism, mental complaints, and also of various personality traits in a normal population at two points of time, 15 years apart. Together with earlier published incidence studies the present monograph is intended to give as complete a picture as possible of the mental morbidity in a total population. Our most conspicuous finding was the increase over time of the prevalence of neurotic illnesses. Depressive illnesses represented the largest increase. In the male sex the rate of Neurosis trebled from Time 1 to Time 2, although the female preponderance still remained. Psychopathy and Alcoholism, on the other hand, were very markedly male disorders. A description of how the investigations were performed is included and also a list of publications originating from the Lundby Study. This book will be of interest to physicians and psychiatrists interested in epidemiology and also to governmental planners and social scientists.

The Facial Discrimination Task (FDT) (Erwin, R.J., Gur, R.C., Gur, R. E., Skolnick, B., Mawhinney-Hee, M., Smailis, J., 1992. Facial emotion discrimination: I. Task construction and behavioural findings in normal participants. Psychiatry Research 42, 231-240.) consists of standardized black-and-white photographs of Caucasian actors exhibiting happy, sad, and neutral faces. Originally designed for brain-imaging research in emotion recognition in schizophrenia and major depression, it has since been successfully employed in emotion recognition studies on mental retardation and psychosomatic disorders. This article presents new basic psychometric data from three studies with a total of 401 college undergraduates. Content validity, item reliability (test-retest, item-total correlation, item difficulty) and test reliability (internal consistency) were established. Happy and sad items were easier to agree upon than neutral ones. In general, happy items had the highest validity, highest test-retest reliability, and highest item-total correlations. Recognition errors of neutral items were biased toward negative affect. Advantages and limitations of the FDT for clinical research applications are discussed.

Whether the Psychopathology Inventory for Mentally Retarded Adults (PIMRA) could detect specific psychopathological disorders was investigated in 652 subjects with different levels of mental retardation living in the community or in residential facilities. An exploratory factor analysis was carried out to check the scale organization of PIMRA. The Anxiety, Adjustment Disorder, Somatoform Disorder, and Soundness Scales were confirmed by 4 corresponding factors; the Psychosexual Disorder Scale was replaced by a factor specific to gender identity problems, and the Schizophrenia Scale by two factors concerning isolation and bizarre behaviors, respectively. The items of the Depression Scale were distributed over the three factors concerning anxiety, adjustment, and psychosomatic disorders, while the items of the Personality Disorder Scale were scattered over almost all the factors. Moreover, 55 subjects with anxiety disorders and 49 with depression were compared to 50 control subjects of the same age, intelligence level, and gender ratio but without dual diagnosis and obtained significantly higher factorial scores both on the overall scale and on the factors specifically related to their disorders. PIMRA has been found to show good construct validity. These results could be considered particularly valid as they were obtained from a large sample comprising different levels of mental retardation and thus showing all possible psychopathological behaviors.
