Co-occurrence of personality disorders with mood, anxiety, and substance use disorders in a young adult population.

The purpose of this study was to determine the co-occurrence of DSM- III-R personality disorders (PDs) with mood, anxiety, and substance use disorders in a young adult population. The members of the Northern Finland 1966 Birth Cohort Project, living in the city of Oulu with an age of 31 years (N = 1,609) were invited to participate in a two-phase field study. The SCID I and II were used as diagnostic instruments.

Somatization and alexithymia in young adult Finnish population.

Background: We assessed alexithymia and alexithymic features among young adult subjects with and without somatization symptoms in an epidemiological setting with a sample of young adults.

Methods: The sample consisted of urban 31-year-old subjects (N=1002). Data on somatization were gathered from a review of all public health outpatient records.

Comparison of hospital-treated personality disorders and personality disorders in a general population sample.

The distribution of personality disorders (PDs) was explored in hospital-treated subjects and in a population subsample. This study forms a part of the Northern Finland 1966 Birth Cohort study. Hospital case records of psychiatric treatment periods of all cohort members (n=11,017) were reviewed and re-checked against DSM-III-R criteria.

Reasons for the diagnostic discordance between clinicians and researchers in schizophrenia in the Northern Finland 1966 Birth Cohort.

Background: The diagnosis of schizophrenia by clinicians is not always accurate in terms of operational diagnostic criteria despite the fact that these diagnoses form the basis of case registers and routine statistics. This poses a challenge to psychiatric research. We studied the reasons for diagnostic discordance between clinicians and researchers.

The Hopkins Symptom Checklist-25 in screening DSM-III-R axis-I disorders.

Simple screening questionnaires for major psychiatric disorders are needed for epidemiological research and clinical work. We describe the characteristics of the Hopkins Symptom Checklist-25 (HSCL-25) as a screening instrument in a two-phase epidemiological survey using the Structured Clinical Interview for DSM-III-R (SCID) as a diagnostic tool. The material consisted of 1609 subjects aged 31 years who were asked to participate in a health survey.

Ability to speak at the age of 1 year and alexithymia 30 years later.

Objective: We studied the association between speech development in the first year of life and alexithymia in young adulthood.

Methods: The study forms a part of the Northern Finland 1966 Birth Cohort. The original material consisted of all liveborn children in the provinces of Lapland and Oulu in Finland with an expected delivery date during 1966.

Social situation of expectant mothers and alexithymia 31 years later in their offspring: a prospective study.

Objective: We studied the association between alexithymia in adulthood and social situation of the child's family at the time of the child's birth.

Methods: The study forms part of the prospective Northern Finland 1966 Birth Cohort Project. The original material consisted of all 12,058 live-born children in the provinces of Lapland and Oulu in Finland with an expected delivery date during 1966.
