Five-year follow-up of first-episode depression treated with psychodynamic psychotherapy or antidepressants.

Psychiatry Res 2019 Feb 28;275:27-30. Epub 2019 Feb 28.

Psychiatric Unit, San Luigi Gonzaga University Hospital, Regione Gonzole 10, 10043, Orbassano, Turin, Italy; Department of Neuroscience, University of Turin, Via Cherasco 15, 10126, Turin, Italy.

Short-term psychodynamic psychotherapy (STPP) both combined with medication and alone has been shown to be effective in major depressive disorder (MDD). However, few studies compared STTP and pharmacotherapy in monotherapy during acute phase and there is lack of data concerning the prevention of recurrences. The aim of this retrospective study was to evaluate the clinical course of patients who achieved remission from their first life-time major depressive episode after treatment with antidepressant (AD) therapy or brief dynamic therapy (BDT), a specific type of STPP, examining the recurrence rates during a 5-year treatment-free period.

Department of Psychiatry and Biobehavioral Sciences, UCLA Integrated Substance Abuse Programs, University of California Los Angeles, 11075 Santa Monica Blvd., Suite 200, Los Angeles, CA 90025, USA. Electronic address:

Studies on the relationships between marijuana use and quality of life have reported mixed findings. Based on a survey of 123 marijuana users conducted in Los Angeles during 2017-2018, we investigated the relationships between marijuana use frequency, severity of marijuana-related problems, and health-related quality of life (HRQoL). Results indicated that (1) marijuana use frequency was positively related to severity of marijuana-related problems; (2) severity of marijuana-related problems was negatively related to mental domain of HRQoL but was not significantly related to physical domain of HRQoL; and (3) marijuana use frequency was positively associated with mental health symptoms and physical health conditions, and both in turn were negatively linked to mental and physical domains of HRQoL, respectively.

Department of Psychology, University of Illinois at Chicago, IL, USA; Department of Psychiatry and Behavioral Sciences, Northwestern University, Chicago, IL, USA. Electronic address:

Heightened responsivity to unpredictable, and perhaps predictable, threat characterizes some internalizing disorders and may be vulnerability factors for psychopathology as well. However, few studies have directly tested whether individual differences in unpredictable and/or predictable threat responding longitudinally predict symptoms of psychopathology and functional outcomes. Examining functioning is particularly important given that functioning is separable from symptoms of psychopathology. Read More

Subjective social status via mediation of childhood parenting is associated with adulthood depression in non-clinical adult volunteers.

Psychiatry Res 2019 Feb 25;274:352-357. Epub 2019 Feb 25.

Department of Psychiatry, Tokyo Medical University, 6-7-1 Nishishinjuku, Shinjuku-ku, Tokyo 160-0023, Japan. Electronic address:

Subjective social status (SSS) is associated with major depression, but its association with depressive symptoms remains unknown. In this study, we hypothesized that SSS mediates the effects of the quality of parenting (care and overprotection) on self-esteem and depressive symptoms in adulthood in non-clinical self-selected adult volunteers, and this hypothesis was verified by covariance structure analysis. The following questionnaire surveys were conducted on 404 Japanese non-clinical adult volunteers: Patient Health Questionnaire-9 (PHQ-9), SSS, Parental Bonding Instrument (PBI), and Rosenberg Self-Esteem Scale (RSES).

Perceived childhood adversities: Impact of childhood trauma to estimated intellectual functioning of individuals with bipolar disorder.

Psychiatry Res 2019 Feb 20;274:345-351. Epub 2019 Feb 20.

Laboratory of Molecular Psychiatry, Hospital de Clínicas de Porto Alegre, Programa de Pós-Graduação em Psiquiatria e Ciências do Comportamento, Universidade Federal do Rio Grande do Sul, Rua Ramiro Barcelos, 2350, Prédio Anexo, Porto Alegre, Rio Grande do Sul 90035-903, Brazi. Electronic address:

Maltreatments in childhood may have implications for neurodevelopment that could remain throughout life. Childhood trauma seems to be associated with the onset of bipolar disorder (BD), and its occurrence might accentuate the overall disease impairments related to cognitive deficits in BD. We aimed to evaluate the effects of a history of childhood trauma to estimated intellectual functioning (IQ) of individuals with BD. Read More

Mapping cortical surface features in treatment resistant schizophrenia with in vivo structural MRI.

Psychiatry Res 2019 Feb 14;274:335-344. Epub 2019 Feb 14.

Cognition Schizophrenia and Imaging Lab, Department of Psychosis Studies, Institute of Psychiatry, Psychology and Neuroscience, King's College London, UK.

Decreases in cortical volume (CV), thickness (CT) and surface area (SA) have been reported in individuals with schizophrenia by in vivo MRI studies. However, there are few studies that examine these cortical measures as potential biomarkers of treatment resistance (TR) and treatment response (NTR) in schizophrenia. This study used structural MRI to examine differences in CV, CT, and SA in 42 adults with schizophrenia (TR = 21, NTR = 21) and 23 healthy controls (HC) to test the hypothesis that individuals with TR schizophrenia have significantly greater reductions in these cortical measures compared to individuals with NTR schizophrenia.

Internalizing symptoms and chronotype in youth: A longitudinal assessment of anxiety, depression and tripartite model.

Psychiatry Res 2019 Feb 27;272:797-805. Epub 2018 Dec 27.

Department of Psychology, University of Illinois at Urbana-Champaign, 603 E. Daniel St. Champaign, IL 61820, USA.

Biological rhythm theories highlight the reciprocal relations between dysregulated circadian patterns and internalizing psychopathology. Chronotype characterizes individuals' diurnal preference, as some exhibit more morningness or eveningness. Previous research suggests that eveningness prospectively predicts depression in adolescence. Read More

Do different factors influence whether girls versus boys meet ADHD diagnostic criteria? Sex differences among children with high ADHD symptoms.

Psychiatry Res 2019 Feb 27;272:765-773. Epub 2018 Dec 27.

Social, Genetic, and Developmental Psychiatry Centre (SGDP), Institute of Psychiatry, Psychology & Neuroscience, King's College London, DeCrespigny Park, Denmark Hill, London SE5 8AF, UK.

We investigate if different factors influence whether girls versus boys meet diagnostic criteria for attention-deficit/hyperactivity disorder(ADHD) among children with high ADHD symptoms. Participants were 283 children aged 7-12 from a population-based study. Girls and boys meeting diagnostic criteria for ADHD, based on an objective investigator-based interview, were compared to children who did not meet criteria despite high symptoms on a rating-scale measure of ADHD.

Stress reactivity in healthy child offspring of parents with anxiety disorders.

Psychiatry Res 2019 Feb 3;272:756-764. Epub 2019 Jan 3.

University of Ottawa, Ottawa, Ontario, Canada; Institut du savoir Montfort, Ottawa, Ontario, Canada.

Several studies suggest that anxiety disorders (AD) involve dysregulation of the autonomic nervous system (ANS) and hypothalamic-pituitary (HPA) axis. However, it is unknown if alterations in these biological systems are premorbid markers of AD risk or a state-dependent feature of anxiety. This study examined ANS and HPA-axis response to a laboratory stressor in healthy child offspring of parents with (n = 55) and without (n = 98) a history of AD. Read More
