Objective: To analyze the use of prescribed psychotropic medication in subjects with personality disorder (PD) diagnosed in early adulthood., Methods: The study population consisted of former adolescent psychiatric inpatients (N=508). 63 had a diagnosis of PD, including with borderline PD (BPD) (N=38) and other PD (OPD) (N=25). DSM IV-based psychiatric diagnoses in adolescence were based on the Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL). The information on in-or outpatient hospital treatments until the end of 2016 were extracted from the National Care Register for Health Care. Lifetime data on purchases of physician-prescribed psychotropic medications was obtained from the Social Insurance Institution of Finland., Results: 98.4% (N=62) of subjects with PD had purchased at least one type of psychotropic medication during the follow-up period. The use of non-opioid analgesics and antipyretics was over twice as common among subjects with BPD than subjects with OPD (57.9% vs.28.0%, p=0.020). Anxiolytic use was 1.5 times more common among subjects with BPD than subjects with OPD (65.8% vs. 40.0%, p=0.044) CONCLUSIONS: Psychotropic medication use was common among subjects with PD. The use of non-opioid analgesics, antipyretics and anxiolytics was more common among subjects with BPD., (Copyright © 2020. Published by Elsevier B.V.)

Objective: To examine the association of personality disorders (PDs) to deaths of drivers in fatal motor vehicle accidents (FMVAs) and analyze gender differences in lifetime psychiatric disorders and medico-legal findings at the time of accident., Method: The study sample consisted of 4810 Finnish drivers killed in FMVAs in Finland between 1990 and 2011. Doctor-diagnosed PD was found in 146 drivers (118 men and 28 women). The information of psychiatric morbidity was obtained from the Finnish Care Register for Health Care., Results: The proportion of deceased drivers with PDs had increased significantly over the study period, particularly among females and those with PD not otherwise specified (NOS). Suicidality and use of medication affecting driving ability were more common among females with PD compared to males with PD. 88% of all deceased drivers with PD had comorbid psychiatric disorders., Conclusion: Our findings indicate that PDs may predispose drivers to FMVAs, particularly females. This study emphasizes the importance of evaluating the fitness-to-drive of subjects with PD and especially comorbid substance use disorders, which may relate to an increased risk of fatal motor accidents., (© 2019 John Wiley & Sons A/S.

We examined the association of bullying behavior in adolescence to personality disorder (PD) diagnosed in early adulthood. The study sample consisted of 508 adolescents (300 girls, 208 boys) who were admitted to psychiatric inpatient treatment between April 2001 and March 2006. Data were based on semi-structured K-SADSPL-interviews and hospital treatments extracted from the Care Register for Health Care (CRHC). At the end of 2013, details of psychiatric diagnoses recorded on hospital discharges and outpatient visits were extracted from the CRHC. This study showed that female victims of bullying have an almost fourfold likelihood of developing a PD later in life compared to adolescents with no involvement in bullying behavior. Most of the females had Borderline PD. Female adolescents diagnosed with anxiety disorder during adolescence had an over threefold risk of developing a PD during late adolescence or early adulthood. Conversely, we found no associations between bullying involvement among men in adolescence and subsequent PDs. Bullying victimization may influence the development of PDs among females. Adolescent services should pay particular attention to female victims of bullying and those displaying symptoms of anxiety disorders.

Background: Our aim was to investigate which clinical and socio-demographic factors among adolescent psychiatric patient aged 13-17 are associated with a diagnosis of personality disorder (PD) in young adulthood after discharge from psychiatric hospitalization., Methods: The study sample consisted of 508 adolescents (ages 13-17) admitted to acute psychiatric impatient care between April 2001 and March 2006. DSM IV-based psychiatric diagnoses were obtained from the Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL). The information on hospital treatments either in out- or inpatient settings until the end of 2012 was extracted from the national Care Register for Health Care provided by the Finnish National Institute for Health and Welfare. The follow-up time was 9.2 years (mean, 95% CI 9.0-9.3 yrs)., Results: Altogether 57 (11.2%) of subjects were diagnosed PD in adulthood. Among girls with anxiety disorders in adolescence the risk for PD in adulthood increased to 4.39-fold (95% CI 2.02-9.53). Males with later PD were more likely to be admitted for hospital treatment from child welfare placements (OR 3.23, 95% CI 1.21-8.61). However, axis I disorders in adolescence was not associated with risk for PD among boys., Conclusions: The results indicate that risk of PD developing later in life is increased among girls with anxiety disorders. A child welfare placement associated with PD in males later in life. These associations in adolescents should be considered in clinical work., (Copyright © 2015 Elsevier Masson SAS.

Background: The association between childhood family structure and sociodemographic characteristics and personality disorders (PDs) in a general population sample was studied., Methods: This study is a substudy of the prospective Northern Finland 1966 Birth Cohort Project with 1588 young adult subjects. The case-finding methods according to the DSM-III-R criteria for PDs were: (1) Structured Clinical Interview for DSM-III-R (SCID) for 321 cases who participated in a 2-phase field study, (2) Finnish Hospital Discharge Register data, and (3) analysis of the patient records in public outpatient care in 1982-1997. Statistical analyses were performed on the association between PDs and family background factors., Results: Altogether 110 (7.0%) of the subjects had at least one probable or definite PD. After adjusting for confounders (gender, parental social class and parental psychiatric disorder) the results indicated that single-parent family type in childhood was associated with cluster B PDs in adulthood. Being an only child in childhood was associated with cluster A PDs. No special childhood risk factors were found for cluster C PDs., Conclusions: Results suggest that single-parent family type at birth and being an only child in the 1960s are associated with PD in adulthood. Further studies are needed to explore the psychosocial aspects of family environment which may nowadays promote vulnerability to PDs in adulthood.

The objective of this study was to describe the temperament dimension profiles assessed by the Temperament and Character Inventory (TCI) among young adults with the DSM-III-R personality disorder (PD). Our hypothesis was that PD clusters and separate PDs can be distinguished from one another by their specific temperament profiles. As a part of the 31-year follow-up survey of the prospective Northern Finland 1966 Birth Cohort, the cohort members living in the city of Oulu at the age of 31 years (n=1609) were invited to participate in a two-phase field study. The Structured Clinical Interview for DSM-III-R for PDs (SCID-II) was used as diagnostic instrument. The final study sample consisted of the 1311 subjects who had completed the Hopkins Symptom Check List-25 questionnaire for screening and had given a written informed consent. Of the 321 SCID interviewed subjects, 74 met the criteria for at least one PD and had completed the TCI. The mean TCI scores of subjects with PD and control subjects without PD (n=910) were compared. Low Novelty Seeking, high Harm Avoidance and low Reward Dependence characterized cluster A and C PDs. Subjects with a cluster B PD did not differ from controls, except for Novelty Seeking, which was high. The temperament dimensions could not distinguish different PDs very well, with the only exception of persons with obsessive-compulsive PD. PD clusters were associated with different profiles of temperament, lending some support for Cloninger's typology.

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. One hundred and seventy-seven out of 321 interviewed subjects met the criteria for mood, anxiety, or substance use disorders. Altogether 72 (41%) of the subjects with an Axis I disorder met the criteria for at least one PD. The weighted co-occurrence rate of any PD varied from 28% for mood disorders to 47% for anxiety disorders. PDs, especially those in Cluster C, are highly associated with Axis I psychiatric disorders in population.

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. A subsample of the cohort members living in Oulu (n=1609) were invited to a two-stage psychiatric field survey with Structured Clinical Interview for DSM-III-R (SCID) as a diagnostic method. The most common PDs in hospital-treated sample were cluster B PDs (erratic). In the population subsample, cluster C PDs (anxious) formed the majority.
