Influence of the suspension of continued treatment with flurazepam and amobarbital on two discrimination learning schedules.
1977
The authors have studied the effect of the suspension of chronic treatment with flurazepam and amobarbital on the operant behavior of rats that for the first time were in the presence of two fixed-interval discrimination schedules. With the sound discrimination schedule, the responses emitted by the treated animals had characteristics similar to those of control animals. With the temporal discrimination schedule, though it is not possible to distinguish between learning rates, modifications in the intensity of the effect (increases in lever pressing) indicate that, considering the doses, the action of flurazepam is slight and that of amobarbital clear and statistically significant.
Syndrome profiles in alcoholism and panic disorder with or without agoraphobia
2002
It is proposed that alcoholism and panic disorder/agoraphobia demonstrate in part common genetic and environmental origins. Shared subthreshold symptom patterns in the parents' generation could confirm the proposed genetic role in alcoholism and panic disorder/agoraphobia, even if the parents do not fulfil the diagnostic criteria for a primary psychiatric diagnosis. This is the first family study of exploratively analyzing subthreshold symptoms in both disorders. The authors investigated families with panic disorder/agoraphobia and/or alcoholism with the Munich-Composite International Diagnostic Interview (M-CIDI). We documented the diagnoses according to Diagnostic and Statistical Manual o…
In search for predictive biomarkers: dissecting the molecular pathways in brain and blood underlying poor and good antidepressant treatment response
2018
Major depression poses a serious social and economic threat to modern societies, as it accounts for more lost productivity compared with any other disorder. There are currently two major problems calling for innovative research approaches: 1. The absence of biomarkers predicting antidepressant response and 2. The lack of conceptually novel antidepressant compounds. Identification of biomarkers could allow patient stratification and enable the selection of pathophysiologically distinct patient subgroups to allow optimized treatment choices based on biology. In search for conceptually novel antidepressants, the hippocampal dentate gyrus is a region of particular interest, as there is a large …
Plasma profile of pro-inflammatory cytokines and chemokines in cocaine users under outpatient treatment: influence of cocaine symptom severity and ps…
2014
The treatment for cocaine use constitutes a clinical challenge because of the lack of appropriate therapies and the high rate of relapse. Recent evidence indicates that the immune system might be involved in the pathogenesis of cocaine addiction and its co-morbid psychiatric disorders. This work examined the plasma pro-inflammatory cytokine and chemokine profile in abstinent cocaine users (n = 82) who sought outpatient cocaine treatment and age/sex/body mass-matched controls (n = 65). Participants were assessed with the diagnostic interview Psychiatric Research Interview for Substance and Mental Diseases according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition,…
Heart rate and blood pressure responses to a competitive role-playing game
2001
The effects of the outcome of competitive encounters on physiological parameters have been studied, especially testosterone levels, but hardly on other systems that, however, present a high sensitivity to stress. This study assessed the effect of a competitive game on heart rate (HR) and blood pressure (BP) in a sample of university students. In addition, the influence of anxiety and attributions of the outcome was also explored. Only winners significantly showed a rise in HR during the competition followed by a decrease along the posttask phase in addition to more internal attributions. On the contrary, the average HR for losers during the competition was lower compared with their baseline…
Willingness to Communicate in a Foreign Language: Evidence from Those Who Approach and Those Who Avoid L2 Communication
2014
It is still unclear why some learners are willing to communicate in a foreign language while others are disinclined to do so. One of the most promising paths of inquiry in this respect is the study of willingness to communicate (WTC), focusing on the volitional process of initiating, maintaining, and terminating communication. That is the reason why the main purpose of this paper is to investigate the testimonials of Polish students with persistently low or high L2 WTC scores obtained during their 3-year secondary grammar school experience. The qualitative results of the study appear to demonstrate that, independently from the individual’s general predilections towards communication in the …
Predictors of mental health during the COVID-19 pandemic in older adults: the role of socio-demographic variables and COVID-19 anxiety
2021
The objective of this study was to evaluate factors related to the mental health of Peruvian older adults during the COVID-19 pandemic. The study had a cross-sectional and observational design. A total of 274 older adults in Lima, Peru (Mage = 67.86) filled out a sociodemographic survey, the Coronavirus Anxiety Scale, Mental Health Inventory-5, Patient Health Questionnaire-2 item, and Generalized Anxiety Disorder Scale. A Structural Equation Model (SEM) was estimated to test an a priori model that relates the sociodemographic variables, COVID-19 Anxiety, psychological well-being, anxiety and depression. The model fit indices indicated a good fit to the data. The socio-demographic variables …
Excessiveness in Symptom-Related Thoughts, Feelings, and Behaviors: An Investigation of Somatic Symptom Disorders in the General Population.
2020
OBJECTIVE The diagnostic criteria of somatic symptom disorder (SSD) emphasize that somatic symptoms receive disease value once they are accompanied by excessive thoughts, feelings, or behaviors. The main objective of this study was to examine what constitutes excessiveness in psychological reactions to somatic complaints and how excessive symptom-related behavior influences self-reported health status and health care utilization. METHODS A national, representative general population survey was performed between January and March 2016 in Germany, including 2395 individuals older than 13 years. Self-report questionnaires (Somatic Symptom Scale-8, Somatic Symptom Disorder-B Criteria Scale) wer…
Coping strategies and postpartum depressive symptoms: A structural equation modelling approach.
2014
AbstractBackgroundVariables such as the mother's personality, social support, coping strategies and stressful events have been described as risk factors for postpartum depression. Structural Equation Modelling (SEM) analysis was used to examine whether neuroticism, perceived social support, perceived life events, and coping strategies are associated with postpartum depressive symptoms at the 8th and 32nd weeks.MethodsA total of 1626 pregnant women participated in a longitudinal study. Different evaluations were performed 8 and 32 weeks after delivery. Several measures were used: the Edinburgh Postnatal Depression Scale (EPDS), the Diagnostic Interview for Genetic Studies (DIGS), the Eysenck…
Timing of Early Maternal Mental Health and Child Cortisol Regulation
2015
Maternal mental health problems can negatively impact children's physiological stress regulation. Yet, little is known of their long-term effects, especially related to the timing of maternal symptoms. We examined how maternal mental health problems during pregnancy versus in the early postpartum period predict children's cortisol levels and diurnal patterns at 10–12 years. Participants were a selection (N = 102) of an original sample of 805 Finnish families, who were followed from the second trimester of pregnancy (T1) to child's age of 2 months (T2) and 12 months (T3), and again at child's age of 10–12 years (T4). Based on the timing of psychological distress and depressive symptoms (T1–T…
