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.

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. [ABSTRACT FROM AUTHOR]

Background: Various psychotropic prescription drugs are known to have potential for misuse. Among teenagers, non-medical use of prescription drugs may predate illicit drug use or occur concomitantly., Aims: Our aim was to examine prescriptions of psychotropic medications among drug crime offenders and non-criminal controls in a psychiatric inpatient cohort of 13-17-year-olds. Our research question was: were prescribed psychotropic and potentially addictive drugs associated with later drug crime offending., Methods: Our sample was of all 60 adolescents who had been convicted of a drug crime by young adulthood with a twice-sized control group, matched for gender, age and family-type, from a cohort of 508 adolescents consecutively admitted to a psychiatric inpatient care in Finland between April 2001 and March 2006. Adolescence-related information on substance use and psychiatric disorders was obtained by semi-structured interviews. Follow-up information on crimes and medication purchases was obtained from Finnish nationwide registers. The association of studied factors to drug crime offending was examined using stepwise binary logistic regression analysis., Results: 75% of drug crime offenders and 47% of non-criminal controls had used addictive psychotropic medications during the follow-up period (p < 0.001). 74% of all drug crime offenders' purchases of prescribed addictive drugs occurred within the year preceding drug crimes. Of addictive drugs, the use of clonazepam and gabapentinoids was most likely to associate with drug crime offending (AOR 7.77, p < 0.001). Conduct and substance use disorders diagnosed in adolescence (AOR 3.49, p = 0.010; AOR 2.34, p = 0.050) were predictors for drug crime offending., Conclusions: Our findings suggest that, when treating young adults with conduct disorder and a history of substance use, physicians should prescribe addictive medications with caution, favouring instead non-addictive medications complemented by psychosocial interventions., (© 2022 The Authors.

This study examined the associations of psychiatric disorders, suicidal behavior and family-related characteristics during adolescence, to subsequent experiences of hospital-treated physical, or sexual assaults, among 508 young adults with a history of psychiatric inpatient care at adolescence (aged 13-17 years). Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) based adolescent psychiatric disorders were assessed at index hospitalization using Schedule for Affective Disorder and Schizophrenia for School-Age children, Present and Lifetime version (K-SADS-PL). Treatment episodes for assaults were obtained from the health care register, provided by the Finnish National Institute for Health Welfare. About 14.4% of the participants had experienced physical or sexual assault during their lifetime. Results of logistic regression analysis indicated that anxiety disorder (odds ratio [OR] = 9.6) and nonsuicidal self-injury (OR = 3.7) in adolescence for males, and personality disorder (OR = 3.4) for females, were associated with increased likelihood for subsequent assault exposure leading to hospitalization. These findings can be used in targeting vulnerable adolescents and designing primary prevention strategies., (© Copyright 2021 Springer Publishing Company, LLC.)

Objective: To analyze an association of eating disorders (EDs) to reproductive health outcomes among former adolescent psychiatric inpatients, hospitalized between the ages 13 and 17 years. The register-based follow-up information on psychiatric comorbidity and use of prescribed addictive psychotropic medication up to early adulthood were also explored., Methods: A total of 31 (10.3%) women with a diagnosed ED were identified from the initial sample of 300 female adolescents, treated in psychiatric inpatient care between 2001 and 2006. The K-SADS-PL and EuropASI research instruments were used to gather information during the adolescent psychiatric hospitalization. The follow-up data for reproductive health outcomes and psychiatric comorbidity up to early adulthood were obtained from the national health care registers. Information on prescribed addictive psychotropic medication was provided by the Social Insurance Institution of Finland. In analyses, EDs were categorized into anorexia nervosa (AN) and other EDs (OED). AN accounted for 58.1% of all EDs. Of OEDs, the majority (69.1%) were bulimia., Results: None of the women with AN, but 53.8% of those with OED had undergone medical abortions by early adulthood. Childbirths were emphasized in women with OED (61.5%) and a history of hospital-treated poisonings in women with AN (55.6%). High nicotine dependence in adolescence (30.8%) was a characteristic of women with OED., Conclusion: Our study findings suggest that OED may expose affected women to various unfavorable reproductive health outcomes, particularly women with a history of psychiatric admissions. Recognizing the differences in young women with different subtypes of ED is important when discussing contraception and pregnancy.

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.)

Background: Maternal depression is common during pregnancy, affecting 10-15% of mothers. In previous reports, the offspring of antenatally depressed mothers have had an elevated risk for antisocial, criminal and violent behaviour in adolescence, and for borderline personality features in childhood, but long-term outcomes are unknown. Aims: To study whether the adult offspring of antenatally depressed mothers have an elevated risk for antisocial (ASPD) or borderline personality disorder (BPD) when followed until mid-adulthood. Methods: In the general population-based Northern Finland 1966 Birth Cohort, mothers of 12,058 children were asked during mid-gestation if they felt depressed. Of the mothers, 14% reported being depressed. The offspring were followed for 49 years. The diagnoses of in- and outpatient-treated ASPD and BPD in the offspring were detected using the Finnish Care Register for Healthcare. Maternal antenatal smoking, newborn´s low birthweight or short gestational age, father's social class, and family type at birth were considered as confounding variables. Logistic regression analyses on the potential confounders were performed. Maternal postnatal depression and paternal ASPD information was not available. Results: In the male offspring of antenatally depressed mothers, the risk for ASPD was elevated (adjusted odds ratio 5.6; 95% confidence interval 1.8-17.8), but not in female offspring. The risk for BPD was not elevated in the offspring of antenatally depressed mothers in this study. Conclusions: The sons of antenatally depressed mothers had an increased risk for ASPD. Prevention and treatment of antenatal depression might present an opportunity to decrease the risk of antisocial personality in the offspring.

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.

Various psychiatric problems in adolescence and early adulthood have been shown to associate with criminal behaviour. In this study the association of personality disorders (PDs) with criminal behaviour was examined in adolescents treated in psychiatric hospitals. The study sample consisted of 508 adolescents (age 13-17) admitted to acute psychiatric impatient care between April 2001 and March 2006. Crime data was obtained from the Finnish Legal Register Centre on September 2013. The Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL) was used to assess psychiatric diagnoses in adolescence. The information on PDs in early adulthood was based on follow-up information on psychiatric treatments in either out- or inpatient settings until the end of 2012, and was extracted from the National Care Register for Health Care provided by the Finnish National Institute for Health and Welfare. A total of 22 (39%) of the 57 subjects with PD had committed a crime. In women, the likelihood for violent criminality was significantly increased in those with Borderline PD (OR 6.09, CI 1.24-29.84, p=0.009) and was also associated with conduct disorder (OR 4.26, CI 1.38-13.19, p=0.012), child welfare placement (OR 11.82, CI 3.61-38.76, p<0.001) and parent's substance use disorder (OR 7.74, CI 2.30-26.10, p=0.001). In men, no association was observed between PD and any kind of criminal behaviour. Significant predictors for violent criminality in males were conduct disorder (OR 4.05, CI 1.75-9.38, p=0.001), substance use disorder (OR 2.51, CI 1.22-5.17, p=0.012) and special services at school (OR 2.58, CI 1.16-5.76, p=0.021). Females with Borderline PD showed an increased risk for violent offending. This suggests Borderline PD as a potential explanatory factor for violent assaults by females and highlights the importance of recognizing the risk for violence in young women with a Borderline PD., (Copyright © 2016 Elsevier Ireland Ltd.

The Temperament and Character Inventory (TCI) was developed to measure the following temperament dimensions: novelty seeking (NS), harm avoidance (HA), reward dependence (RD) and persistence (P). These four dimensions of temperament were originally proposed to be independent of one another. In this study the inter-relationships between the dimensions were studied with meta-analytic techniques. We also studied the effects of sociodemographic factors (location of the study, mean age and gender distribution) on correlations between temperament dimensions. We searched studies on healthy (non-clinical) populations that used the TCI (version 9), and that had a required sample size of at least 100. The search resulted in 16 articles. The resulted pooled correlation coefficient was medium level between NS and HA (-0.27). Correlations were small for HA-P (-0.20), NS-P (-0.14), NS-RD (0.10), RD-P (0.05) and HA-RD (0.04). In meta-regression, the correlation NS-P was significantly affected by the location of the study (Asian/other) and by the gender distribution of the sample. In the HA-P correlation, the mean age of the sample affected the correlation. In conclusion, we found a medium level negative correlation between NS and HA; other correlations between the dimensions were small. These findings mainly support Cloninger's theory of independent dimensions.

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.

Objective: We assessed the temperament profiles of young adult somatizers in an epidemiological setting. We hypothesized that somatizers would have a characteristic temperament profile., Methods: The sample consisted of 984 subjects at the age of 31 years. Data on somatization were gathered from a review of all public health outpatient records. Subjects with four or more somatization symptoms according to the DSM-III-R criteria were classified as somatizers. Temperament profiles were assessed using the Temperament and Character Inventory (TCI)., Results: Six males (1.3%) and 61 females (11.5%) met our criteria for somatization. Harm avoidance and reward dependence of the TCI profiles were associated with somatization symptoms in the whole sample. In logistic regression analysis, sex and psychological distress were associated with somatization but not with temperament profiles., Conclusion: We did not find a characteristic temperament profile for somatizers. This finding is in contrast to suggestions that somatization is associated with temperament profiles.

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.

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., Methods: The Northern Finland 1966 Birth Cohort (n = 11,017) was followed from mid-gestation to the end of the 31st year. Psychiatric outcome was ascertained through linkage to the national hospital discharge register containing clinical diagnoses made by the attending physician. The hospital notes of all subjects admitted to hospital during the period 1982-1997 due to psychiatric disorder were reviewed and 475 research, operational DSM-III-R diagnoses were formulated., Results: Ninety-six cases met operational criteria for schizophrenia. Fifty-five (57 %) had concordant diagnoses: both the clinical and research diagnoses were schizophrenia. Forty-one (43 %) had discordant diagnoses: the clinical diagnosis was other than schizophrenia (mainly schizophreniform or other psychosis). Discordant cases were more likely to be older at onset, experience a shorter treatment duration, fewer treatment episodes, and to have a comorbid diagnosis mental retardation., Conclusions: Clinicians do not make the diagnosis of schizophrenia as often as the application of operational criteria would suggest they should. The discordance between clinical diagnosis and the research, operational diagnosis is especially likely in cases having late onset and few contacts to psychiatric hospital.

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. The invitation included the HSCL-25 questionnaire. All "screen-positive" (HSCL-25 mean>/=1.55) subjects and every tenth "screen-negative" subject were invited to participate in the SCID interview. The sensitivity of the HSCL-25 for any present DSM-III-R axis-I psychiatric disorder was 48%. The specificity was 87%. The sensitivity of cases with comorbid psychiatric disorders was 100%. The HSCL-25 is a moderate instrument for screening with present axis-I DSM-III-R psychiatric disorders in a young adult population. It can be recommended for screening of psychiatric disorders.
