- Internet-delivered cognitive behaviour therapy (ICBT) has existed for 20 years and there are now several controlled trials for a range of problems. In this paper, we focused on recent meta-analytic reviews of the literature and found moderate to large effects reported for panic disorder, social anxiety disorder, generalized anxiety disorder, posttraumatic stress disorder, and major depression. In total, we reviewed 9 recent meta-analytic reviews out of a total of 618 meta-analytic reviews identified using our search terms. In these selected reviews, 166 studies were included, including overlap in reviews on similar conditions. We also covered a recent review on transdiagnostic treatments and 2 reviews on face-to-face v. internet treatment. The growing number of meta-analytic reviews of studies now suggests that ICBT works and can be as effective as face-to-face therapy.

Tidskriftsartikel (refereegranskat)abstract
- This overview focuses on the cognitive transition between normal aging and dementia. Numerous studies indicate that individuals who will go on to develop dementia show cognitive deficits many years before the time at which a clinical diagnosis could be rendered. The degree of preclinical impairment is remarkably similar for tasks assessing episodic memory, executive functioning, and perceptual speed, consistent with the view that multiple brain alterations occur prior to clinical disease onset. Although most research in this area has dealt with Alzheimer disease (AD), several recent reports indicate that the pattern of preclinical impairment is very similar in the second largest dementia disorder, vascular dementia (VaD). This is important because currently the possibility for interventions to postpone disease onset is greater in VaD than in AD. Despite pronounced preclinical cognitive deficits in dementia, the performance distributions between cases and controls are largely overlapping, hampering the ability to identify high-risk individuals. To alleviate this problem, future research should evaluate hybrid models for the prediction of dementia. In such models, multiple indicators of cognitive functioning should be included along with markers from other domains that have been linked to subsequent dementia (such as brain imaging, genetics, and lifestyle variables). To the extent that these categories of variables add unique variance, classification accuracy will increase and the overlap in performance scores between incident cases and controls will decrease, thereby enhancing clinical usefulness. This approach would also facilitate the examination of interactive effects among classes of preclinical markers.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: Little research has focused on the relation of immigration and suicidal behaviour in youth. Nevertheless, the impact of migration on the mental health of youth is an issue of increasing societal importance. This review aimed to present studies on the prevalence of suicidal behaviour in immigrant youth in various countries and to provide possible explanations for suicidal behaviour in immigrant youth, especially regarding acculturation.METHODS: The review included a literature search to locate articles on the subject of suicidal behaviour in immigrant youth in the context of acculturation.RESULTS: Studies on suicidal behaviour in culturally diverse youth are few and most of the existing research does not differentiate ethnic minorities from immigrants. Studies on epidemiology and on specific risk factors were found regarding various immigrant youth including Hispanics in the United States, Asians in North America and Europe, as well as comparative studies between different immigrant groups in specific countries.CONCLUSIONS: The relation between immigration status and suicidal behaviours in youth appears to vary by ethnicity and country of settlement. Time spent in the new country as well as intergenerational communication and conflicts with parents have, in many of the studies, been related to suicidality in immigrant youth. Summing up, there is a clear and urgent need to further pursue the work in this field, to develop targeted public health interventions as well as psychosocial treatment for preventing suicide in these youth.

The contribution of social factors to the development of schizophrenia: A review of recent findings
- 2007

Forskningsöversikt (refereegranskat)abstract
- Objective: To investigate recent evidence suggesting that social factors are causally related to the development of schizophrenia. Method: I conducted a sytematic review of MEDLINE to identify possibly relevant studies. The search was limited to peer-reviewed studies and review articles appearing in English-language journals since 1996. Studies were included if they used standardized diagnostic criteria for schizophrenia or standardized assessment instruments for psychotic symptoms. Results: Studies of migrants to western Europe provide compelling support for the notion that social factors contribute to the development of schizophrenia. Findings such as excessively high risk for schizophrenia in second-generation immigrants are difficult to explain solely in terms of biological or genetic factors. A growing number of studies implicate childhood exposure to social adversity as a risk factor for schizophrenia, although few studies have used prospective designs. The increased incidence of schizophrenia risk associated with urban birth and (or) urban upbringing suggests possible social causation, but these findings are more ambiguous. Thus far, no studies have explored actual mechanisms by which exposure to social factors might generate psychotic symptoms, although animal experiments suggest that social defeat or social exclusion may cause dopamine dysregulation or sensitization. Conclusions: The accumulating evidence suggesting a role for social factors in the development of schizophrenia arises primarily from studies of migrants conducted in Europe. The mechanisms by which social factors exert their influence remain unknown. Future investigations of social causation should clarify the temporal relation between exposure to social defeat and (or) social adversity and the development of psychotic symptoms.

Psychiatric disorder in detained male adolescents as risk factor for serious recidivism
- 2011

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: A growing body of research consistently shows that detained minors bear substantial mental health needs. However, the relation between mental disorder and criminal recidivism has largely remained unexplored. Our study examines whether psychiatric disorders increase the likelihood of recidivism after controlling for time at risk, criminal history, and the presence of other disorders.METHOD: Participants (n = 232) were detained male adolescents from all 3 youth detention centres in Flanders, Belgium, who were interviewed with the Diagnostic Interview Schedule for Children, Version IV. Two to 4 years later, information on serious recidivism was retrieved from the official judicial registration system. Serious recidivism was defined as having at least one arrest charge for violent, severe property crime, or substance-related offences.RESULTS: Serious recidivism was high, with 81% (n = 191) of the participants being rearrested. Psychiatric disorders predicted neither serious recidivism in general nor violent and severe property recidivism. However, other drug use disorder (OR 2.41; 95% CI 1.22 to 4.75) and general comorbidity (OR 2.64; 95% CI 1.40 to 4.99) were significantly predictive of substance-related recidivism.CONCLUSION: Common psychiatric disorders in detained male adolescents do not significantly increase the likelihood of subsequent arrests, with the exception that substance use disorders appear to increase the risk of later substance-related recidivism. Effective treatment of these disorders may prevent detained juveniles to experience the detrimental outcomes associated with substance-related crimes as adults (for example, mental illness).

Forskningsöversikt (refereegranskat)abstract
- OBJECTIVE: To provide a best estimate of the prevalence of psychiatric disorders among detained male adolescents, with particular emphasis on impairment, multi-informant assessment, and race or ethnicity.METHOD: Computer-assisted searches were executed to identify relevant studies.RESULTS: Fifteen studies using adolescents as informants met inclusion criteria (n = 3401), of which only 2 reported within a subsample on parent-derived diagnoses. The mean prevalence of any disorder was 69.9% (95% CI 69.5% to 70.3%); with conduct disorder occurring most frequently (46.4%, 95% CI 45.6% to 47.3%), followed by substance use disorder (45.1%, 95% CI 44.6% to 45.5%), oppositional defiant disorder (19.8%, 95% CI 19.2% to 20.3%), and attention-deficit hyperactivity disorder (13.5%, 95% CI 13.2% to 13.9%). Although lower, rates for internalizing disorders were still substantial, with any anxiety disorder found in 15.9% (95% CI 15.6% to 16.1%), major depression in 12.0% (95% CI 11.7% to 12.2%), and posttraumatic stress disorder in 9.6% (95% CI 9.2% to 10.0%). Three studies reported on psychotic disorders, finding low rates (1.35%, 95% CI 1.32% to 1.39%). Estimates of prevalence were only marginally different when impairment was not required, while consistency between adolescents and parents was poor. Findings on the relations between race or ethnicity were too scarce and inconsistent to interpret.CONCLUSION: Detained male adolescents bear substantial mental health needs, emphasizing the need to organize effective mental health services for this troubled group. However, our knowledge on mental disorders in detained youth should be enhanced, in particular regarding the reliability of adolescents, compared with parent report, and whether clinically relevant differences exist by race or ethnicity.

- No recent meta-analysis has examined the effects of cognitive-behavioural therapy (CBT) for adult depression. We decided to conduct such an updated meta-analysis. Methods: Studies were identified through systematic searches in bibliographical databases (PubMed, PsycINFO, Embase, and the Cochrane library). We included studies examining the effects of CBT, compared with control groups, other psychotherapies, and pharmacotherapy. Results: A total of 115 studies met inclusion criteria. The mean effect size (ES) of 94 comparisons from 75 studies of CBT and control groups was Hedges g = 0.71 (95% CI 0.62 to 0.79), which corresponds with a number needed to treat of 2.6. However, this may be an overestimation of the true ES as we found strong indications for publication bias (ES after adjustment for bias was g = 0.53), and because the ES of higher-quality studies was significantly lower ( g = 0.53) than for lower-quality studies ( g = 0.90). The difference between high- and low-quality studies remained significant after adjustment for other study characteristics in a multivariate meta-regression analysis. We did not find any indication that CBT was more or less effective than other psychotherapies or pharmacotherapy. Combined treatment was significantly more effective than pharmacotherapy alone ( g = 0.49). Conclusions: There is no doubt that CBT is an effective treatment for adult depression, although the effects may have been overestimated until now. CBT is also the most studied psychotherapy for depression, and thus has the greatest weight of evidence. However, other treatments approach its overall efficacy.

Using qualitative research to inform mental health policy
- 2008
-
Ingår i: Canadian journal of psychiatry. - 0706-7437. ; 53:3, s. 137-144
-
Forskningsöversikt (refereegranskat)abstract
- This article offers examples of the ways in which qualitative methods have informed, and may inform, mental health policy in Canada and beyond. Three initial uses of these methods are identified: to generate hypotheses to be tested by other means; to explore the subjective experiences and everyday lives of people with mental illnesses; and to investigate processes of recovery and the active role of the individual in recovery. Given the recent focus in mental health policy in Canada, the United States, and around the world on transforming mental health systems to promote recovery and the emphasis recovery places on the individual's own first-hand perspective, we argue that qualitative methods will become increasingly useful as psychiatry shifts away from symptom reduction to enabling people to live satisfying, hopeful, and meaningful lives in the community.

A Prospective Study of Childhood Predictors of Traumatic Brain Injuries Sustained in Adolescence and Adulthood
- 2020
-
Ingår i: Canadian journal of psychiatry. - : SAGE Publications. - 0706-7437 .- 1497-0015. ; 65:1, s. 36-45

Tidskriftsartikel (refereegranskat)abstract
- Objective: Traumatic brain injuries (TBIs) are sustained by approximately 17% of males in the general population, many of whom subsequently present mental disorders, cognitive, and physical problems. Little is known about predictors of TBIs and how to prevent them. The present study aimed to determine whether inattention-hyperactivity and/or all externalizing problems presented by boys at age 10 predict subsequent TBIs to age 34 after taking account of previous TBIs and family social status (FSS). Method: 742 Canadian males were followed, prospectively, from age 6 to 34. Diagnoses of TBIs were extracted from health files, parents-reported sociodemographic and family characteristics at participants' age 6, and teachers-rated participants' behaviors at age 10. Separate logistic regression models predicted TBIs sustained from age 11 to 17 and from age 18 to 34. For each age period, two models were computed, one included previous TBIs, inattention-hyperactivity, FSS, and interaction terms, the second included previous TBIs, externalizing problems, FSS, and interaction terms. Results: In models that included inattention-hyperactivity, TBIs sustained from age 11 to 17 were predicted by age 10 inattention-hyperactivity (odds ratio [OR] = 1.46, 1.05 to 2.05) and by TBIs prior to age 11 (OR = 3.50, 1.48 to 8.24); TBIs sustained from age 18 to 34 were predicted by age 10 inattention-hyperactivity (OR = 1.31, 1.01 to 170). In models that included all externalizing problems, TBIs from age 11 to 17 were predicted by prior TBIs (OR = 3.66, 1.51 to 8.39); TBIs sustained from age 18 to 34 were predicted by age 10 externalizing problems (OR = 1.45, 1.12 to 1.86). Neither FSS nor interaction terms predicted TBIs in any of the models. Conclusions: Among males, using evidence-based treatments to reduce inattention-hyperactivity and externalizing problems among boys could, potentially, decrease the risk of TBIs to age 34. Further, boys who sustain TBIs in childhood require monitoring to prevent recurrence in adolescence.

-
Tidskriftsartikel (refereegranskat)abstract
- To review findings with clinical relevance that add to knowledge about antisocial and aggressive behaviour among persons with schizophrenia. Method: Nonsystematic literature review. Results: Recent evidence shows that individuals who develop schizophrenia present cognitive deficits, psychotic-like experiences, and internalizing and externalizing problems from childhood onwards. Many of their relatives present not only schizophrenia-related disorders but also antisocial behaviour. While the increased risk of aggressive behaviour among persons with schizophrenia has been robustly established, recent findings show that by first contact with clinical services for psychosis, most people with schizophrenia who will engage in aggressive behaviour may be identified. At first episode, 2 distinct types are distinguishable: those who present a history of antisocial and aggressive behaviour since childhood and those who began engaging in aggressive behaviour as illness onsets. Antipsychotic medications and other treatments shown to be effective for schizophrenia are needed by both types of patients. Additionally, those with a history of antisocial and aggressive behaviour since childhood require cognitive-behavioural programs aimed at reducing these behaviours and promoting prosocial behaviour. Reducing physical victimisation and cannabis use will likely reduce aggressive behaviour. Evidence suggests that threats to hurt others often precede assaults. Conclusions: At first contact with services, patients with schizophrenia who have engaged in aggressive behaviour should be identified and treated for schizophrenia and for aggression. Research is needed to identify interactions between genotypes and environmental factors, from conception onwards, that promote and that protect against the development of aggressive behaviour among persons with schizophrenia.

-
Tidskriftsartikel (refereegranskat)abstract
- Objective: To examine associations of teacher-rated conduct problems (CP) and hurtful and uncaring behaviours (HUB) at age 6 and 10 with criminal convictions up to age 24 among 1593 males and 1423 females, and to determine whether aggressive behaviour at age 12 mediated the associations of CP and HUB with criminal convictions. Method: Teachers assessed HUB and CP at ages 6 and 10 and ratings above the 90th percentile at each age and within each sex were used to assign participants to 1 of 4 groups. Teachers assessed proactive, reactive, indirect, and verbal aggression at age 12. Juvenile and adult criminal records were obtained. Results: High CP and HUB males, aged 6, were 4 times more likely than males with lower ratings to acquire convictions for violent crimes and 5 times more likely to acquire convictions for nonviolent crimes by age 24. High HUB and CP females, aged 6, were 5 times more likely than females with lower ratings to have a conviction for a nonviolent offence by age 24. Among males, both aged 6 and 10, high HUB without CP were associated with elevations at risk of convictions for violent and nonviolent crimes, while among females the elevations at risk were limited to convictions for nonviolent crimes. Different types of aggressive behaviour mediated associations of high HUB and CP with subsequent criminal convictions, but not the association of HUB without CP and crime. Conclusions: Teachers in elementary schools rated behaviours that, from age 6 onward, significantly predicted criminal convictions into early adulthood.

-
Ingår i: Canadian journal of psychiatry. - 0706-7437. ; 45:4, s. 349-356
-
Tidskriftsartikel (refereegranskat)abstract
- Objective: To assess the associations between staff feelings toward patients and the patients' diagnoses, in view of the fact that clinical reports of such associations have not been corroborated by systematic research. Method: At 24 psychiatric units, 143 patients were assessed according to their personality organization, and staff feelings toward these patients were followed for 5 years. The feelings were reported on a feeling checklist twice yearly, and outcome was assessed as the effect size at year 5, using ratings on Kernberg's structural model complemented with ratings on Strauss-Carpenter's function scale. Results: The study showed that it was possible, using discriminant analyses, to separate diagnostic groups by the different feelings that they evoked in the staff: Patients with borderline personality organization (BPO) evoked fewer relaxed and more aggressive feelings, in contrast to patients with psychotic personality organization (PPO). In contrast to patients with neurotic personality organization (NPO), who evoked feelings of sympathy and helpfulness, PPO patients evoked more feelings of insufficiency and disappointment. A stepwise discriminant analysis of reactions to patients with positive treatment outcome separated the 3 personality organizations with 2 functions using only 2 feelings, "relaxed" and "objective. " The feeling relaxed separated the NPO patients from the BPO patients, and the feeling objective separated the PPO patients from the other groups. The patients' diagnoses accounted for larger proportions of variance in feelings for the patients with positive outcome. Conclusion: The results implied that the patients' different personality organizations evoked different staff feelings in this treatment context and that positive treatment outcome was associated with more pronounced and clear-cut staff reactions.

- To compare the prevalence rates of mental disorders among children of parents with bipolar disorder and of parents with no mental disorders.Method:Seventeen studies, meeting specific selection criteria, were included in the metaanalyses. Risks for mental disorders among children were estimated by aggregating raw data from the selected studies.Results:Results indicate that in comparison with children of parents with no mental disorders, children of parents with bipolar disorder are 2.7 times more likely to develop any mental disorder and 4.0 times more likely to develop an affective disorder. The metaanalyses indicate that during childhood and adolescence, the risks for any mental disorder and for affective disorders in children are consistently but moderately related to having a parent who suffers from bipolar disorder.Conclusions:Risk factors that could account for the psychopathology observed in children of bipolar parents are explored.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To compare frequencies of suicide attempt repetition in immigrants and local European populations, and the timing of repetition in these groups.METHOD: Data from 7 European countries, comprising 10 574 local and 3032 immigrant subjects, were taken from the World Health Organization European Multicentre Study on Suicidal Behaviour and the ensuing Monitoring Suicidal Behaviour in Europe (commonly referred to as MONSUE) project. The relation between immigrant status and repetition of suicide attempt within 12-months following first registered attempt was analyzed with binary logistic regression, controlling for sex, age, and method of attempt. Timing of repetition was controlled for sex, age, and the recommended type of aftercare.RESULTS: Lower odds of repeating a suicide attempt were found in Eastern European (OR 0.50; 95% CI 0.41 to 0.61, P < 0.001) and non-European immigrants (OR 0.68; 95% CI 0.51 to 0.90, P < 0.05), compared with the locals. Similar patterns were identified in the sex-specific analysis. Eastern European immigrants tended to repeat their attempt much later than locals (OR 0.58; 95% CI 0.35 to 0.93, P < 0.05). In general, 32% of all repetition occurred within 30 days. Repetition tended to decrease with age and was more likely in females using harder methods in their index attempt (OR 1.29; 95% CI 1.08 to 1.54, P < 0.01). Large variations in the general repetition frequency were identified between the collecting centres, thus influencing the results.CONCLUSIONS: The lower repetition frequencies in non-Western immigrants, compared with locals, in Europe stands in contrast to their markedly higher tendency to attempt suicide in general, possibly pointing to situational stress factors related to their suicidal crisis that are less persistent over time. Our findings also raise the possibility that suicide attempters and repeaters constitute only partially overlapping populations.

Tidskriftsartikel (refereegranskat)abstract
- Objective:Nightmares are relatively common in patients experiencing psychosis but rarely assessed or treated. Nightmares may maintain persecutory delusions by portraying fears in sensory-rich detail. We tested the potential benefits of imagery-focused cognitive behavioural therapy (CBT) for nightmares on nightmare severity and persecutory delusions.Method: This assessor-blind parallel-group pilot trial randomized 24 participants with nightmares and persecutory delusions to receive CBT for nightmares delivered over 4 weeks in addition to treatment as usual (TAU) or TAU alone. Assessments were at 0, 4 (end of treatment), and 8 weeks (follow-up). Feasibility outcomes assessed therapy uptake, techniques used, satisfaction, and attrition. The primary efficacy outcome assessed nightmare severity at week 4. Analyses were intention to treat, estimating treatment effect with 95% confidence intervals (CIs).Results:All participants offered CBT completed therapy (mean [SD], 4.8 [0.6] sessions) with high satisfaction, and 20 (83%) participants completed all assessments. Compared with TAU, CBT led to large improvements in nightmares (adjusted mean difference = -7.0; 95% CI, -12.6 to -1.3; d = -1.1) and insomnia (6.3; 95% CI, 2.6 to 10.0; d = 1.4) at week 4. Gains were maintained at follow-up. Suicidal ideation was not exacerbated by CBT but remained stable to follow-up, compared with TAU, which reduced at follow-up (6.8; 95% CI, 0.3 to 3.3; d = 0.7). CBT led to reductions in paranoia (-20.8; 95% CI, -43.2 to 1.7; d = -0.6), although CIs were wide. Three serious adverse events were deemed unrelated to participation (CBT = 2, TAU = 1).Conclusions:CBT for nightmares is feasible and may be efficacious for treating nightmares and comorbid insomnia for patients with persecutory delusions. It shows promise on paranoia but potentially not on suicidal ideation.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To assess the impact on knowledge and attitudes of a tailored educational intervention on depression using a modified version of the Prochaska stages of change model, compared with standard continuing medical education, for general practitioners (GPs) in primary care in Iran. Method: Using a randomized controlled trial, a total of 192 GPs were evenly randomized to intervention or control arm. The topic for the educational intervention was depressive disorders. The participants were divided in to small and large groups, depending on their initial stage of change. The GPs' knowledge and skills regarding management of depressive disorders were assessed through a questionnaire with 7 multiple choice questions, 11 Likert statements, 3 case vignettes, and 1 essay question. Attitudes toward management of depressive disorders were also assessed. Both questionnaires were validated. Results: There was a significant improvement in knowledge mean scores regarding multiple choice and Likert questions (intervention effect 6%; P = 0.002), as well as for the case vignettes and essay question (intervention effect 12%; P = 0.011) in the intervention arm, in comparison with the control ann. There were significant changes in mean attitude scores in both study arms, but no difference between them. Conclusions: A theoretical model of medical learning and behavioural change can be used to devise educational formats that suit different stages of learning. Such tailored educational formats can improve GPs' knowledge and skills regarding management of depressive disorders.

Forskningsöversikt (refereegranskat)abstract
- Recent research has shown that depression, anxiety disorders, and psychosis are more common than previously supposed in elderly populations without dementia. It is unclear whether the frequency of these disorders increases or decreases with age. Clinical expression of psychiatric disorders in old age may be different from that seen in younger age groups, with less and often milder symptoms. Concurrently, comorbidity between different psychiatric disorders is immense, as well as comorbidity with somatic disorders. Cognitive function is often decreased in people with depression, anxiety disorders, and psychosis, but whether these disorders are risk factors for dementia is unclear. Psychiatric disorders in the elderly are often related to cerebral neurodegeneration and cerebrovascular disease, although psychosocial risk factors are also important. Psychiatric disorders, common among the elderly, have consequences that include social deprivation, poor quality of life, cognitive decline, disability, increased risk for somatic disorders, suicide, and increased nonsuicidal mortality.

- The Maternal Mental Health in Canada, 2018/2019, survey reported that 18% of 7,085 mothers who recently gave birth reported “feelings consistent with postpartum depression” based on scores ≥7 on a 5-item version of the Edinburgh Postpartum Depression Scale (EPDS-5). The EPDS-5 was designed as a screening questionnaire, not to classify disorders or estimate prevalence; the extent to which EPDS-5 results reflect depression prevalence is unknown. We investigated EPDS-5 ≥7 performance relative to major depression prevalence based on a validated diagnostic interview, the Structured Clinical Interview for DSM (SCID). Methods: We searched Medline, Medline In-Process & Other Non-Indexed Citations, PsycINFO, and the Web of Science Core Collection through June 2016 for studies with data sets with item response data to calculate EPDS-5 scores and that used the SCID to ascertain depression status. We conducted an individual participant data meta-analysis to estimate pooled percentage of EPDS-5 ≥7, pooled SCID major depression prevalence, and the pooled difference in prevalence. Results: A total of 3,958 participants from 19 primary studies were included. Pooled prevalence of SCID major depression was 9.2% (95% confidence interval [CI] 6.0% to 13.7%), pooled percentage of participants with EPDS-5 ≥7 was 16.2% (95% CI 10.7% to 23.8%), and pooled difference was 8.0% (95% CI 2.9% to 13.2%). In the 19 included studies, mean and median ratios of EPDS-5 to SCID prevalence were 2.1 and 1.4 times. Conclusions: Prevalence estimated based on EPDS-5 ≥7 appears to be substantially higher than the prevalence of major depression. Validated diagnostic interviews should be used to establish prevalence.

- OBJECTIVE: To investigate whether childhood sociodemographic factors and parental psychopathology affect suicide risk differently in men and women. METHOD: Cox regressions were used to calculate interaction effects of gender for childhood and parental risk factors for 8815 suicides (27% women) in a national cohort of 2.47 million people born between 1946 and 1968. RESULTS: Low parental socioeconomic status increased suicide risk only for men, hazard ratio (HR) = 1.22 (P = 0.003 for gender interaction), while living in a metropolitan area increased the risk only for women, HR = 1.42 (P < 0.001 for gender interaction). Parental psychotic or affective disorder increased suicide risk more strongly for women (HR = 2.08), than for men (HR = 1.52) (P = 0.004 for gender interaction). CONCLUSION: Growing up in an urban environment and parental psychotic or affective disorder are significant gender-related risk factors for suicide, both conveying higher risks in women. The mechanisms linking childhood urbanicity to increased risk of suicide in adult women stand out as an important research area for the future.

- To compare the risk of ectopic pregnancy among women with and women without antidepressant prescriptions around conception and examine whether this risk differs by prepregnancy depression status. Methods: We conducted a cohort study of all pregnancies between November 1, 2008, and September 30, 2015, identified in the nationwide (American) IBM® MarketScan® Databases. At least one day’s supply of antidepressants in the 3 weeks after a woman’s last menstrual period defined active antidepressant use around conception. At least one depression diagnosis in the year before the last menstrual period defined prepregnancy depression. Relative risk (RR) of ectopic pregnancy was estimated using unadjusted and inverse probability of treatment (IPT)-weighted log-binomial models. Results: Of the 1,703,245 pregnancies, 106,788 (6.3%) women had a prepregnancy depression diagnosis. Among women with a depression diagnosis, 40,287 (37.7%) had an active antidepressant prescription around conception; the IPT-weighted risk of ectopic pregnancy was similar among women who did and did not fill an antidepressant prescription around conception (IPT-weighted RR = 1.01; 95% CI, 0.93 to 1.10). Overall, the risk of ectopic pregnancy was higher among women who had a prepregnancy depression diagnosis than women who did not have a prepregnancy depression diagnosis (IPT-weighted RR = 1.09; 95% CI, 1.04 to 1.15). Conclusions: This study’s findings suggest that women who have a prepregnancy depression diagnosis are at a slightly increased risk of ectopic pregnancy, and among women who have a prepregnancy depression diagnosis, the use of antidepressants around conception does not increase the risk of ectopic pregnancy.
