High Anger Expression is Associated with Reduced Cortisol Awakening Response and Health Complaints in Healthy Young Adults
2016
AbstractThe extant evidence suggests a robust positive association between expression (anger expression-out) and suppression (anger expression-in) of anger and compromised health. Nevertheless, the underlying psychobiological mechanisms which explain these relationships are not well understood. This study examined whether anger expression would predict general health, cortisol awakening response (CAR) and evening cortisol levels in a community sample of 156 healthy young adults of both genders. Participants were distributed into two groups according to their anger expression scores: high and low anger expression (HAE and LAE, respectively). Findings indicated that those with HAE had worse s…
Genome-wide association data provide further support for an association between 5-HTTLPR and major depressive disorder.
2013
Abstract Background Dysfunctions of serotonergic neurotransmission are supposed to be involved in the pathogenesis of psychiatric disorders such as major depressive disorder (MDD). The concentration of serotonin (5-hydroxytryptamine, 5-HT) in the synaptic cleft is essentially regulated by the 5-HT transporter (5-HTT). A length polymorphism repeat in the 5-HTT promoter region, termed 5-HTTLPR, has been commonly investigated for an association with psychiatric disorders. Methods Genotyping of the 5-HTTLPR is time-consuming and technically challenging. Recently, a two-SNP haplotype was identified that tags the 5-HTTLPR at r 2 =0.775. This allows extraction of 5-HTTLPR genotype information from…
Meaning in life moderates hopelessness, suicide ideation, and borderline psychopathology in participants with eating disorders: A longitudinal study
2020
Participants with eating disorders (EDs) experience identity problems, hopelessness, and suicide ideation. Research has confirmed the link between the experience of low meaning in life (MIL) and psychopathology. However, there is a lack of research focusing on MIL in ED. Objectives The objectives of this study are as follows: (a) to analyze whether MIL at baseline moderates the association between ED psychopathology at baseline and borderline symptoms, hopelessness, and suicide ideation at follow-up and (b) to analyze whether MIL moderates the association between suicide ideation, hopelessness, and borderline symptoms at baseline and at the 7-month follow-up. Method The sample was composed …
Mood-congruent bias and attention shifts in the different episodes of bipolar disorder
2013
An "affective" go/no-go task was used in the different episodes of bipolar patients (euthymic, depressed, and manic) to examine (1) the presence of a mood-congruent attentional bias; and (2) the patients' ability to inhibit and invert associations between stimuli and responses through blocks. A group of healthy individuals served as controls. Results revealed a mood-congruent attentional bias: patients in the manic episode processed positive information faster, whereas those in the depressive episode processed negative information faster. In contrast, neither euthymic patients nor healthy individuals showed any mood-congruent biases. Furthermore, there was a shift cost across blocks for hea…
Attention orienting and inhibitory control across the different mood states in bipolar disorder: An emotional antisaccade task
2013
An antisaccade experiment, using happy, sad, and neutral faces, was conducted to examine the effect of mood-congruent information on inhibitory control (antisaccade task) and attentional orienting (prosaccade task) during the different episodes of bipolar disorder (BD) - manic (n=22), depressive (n=25), and euthymic (n=24). A group of 28 healthy controls was also included. Results revealed that symptomatic patients committed more antisaccade errors than healthy individuals, especially with mood-congruent faces. The manic group committed more antisaccade errors in response to happy faces, while the depressed group tended to commit more antisaccade errors in response to sad faces. Additionall…
The Outcome Questionnaire 45.2. Italian validation of an instrument for the assessment of phychological treatments
2008
SummaryAims– The Outcome Questionnaire (OQ-45.2; Lambertet al., 2004) was designed to measure important areas of functioning (symptoms, interpersonal problems and social role functioning) that are of central interest in mental health. The crosscultural validity of the OQ-45.2 in the Italian population has been examined by comparing the psychometric properties and equivalence in factor structure and normative scores of the Italian OQ with the original American version.Method– Data were collected at university (N=461), in community (N=61) and in three mental health care organisations (N=301).Results– Results showed that the psychometric properties of the Italian OQ were adequate and similar t…
Relationship Between Regional Cerebral Blood Flow and Electrocorticographic Activities Under Sevoflurane and Isoflurane Anesthesia
2010
The aims of this study are (1) to assess the effects of volatile anesthetics on regional cerebral blood flow (rCBF) and electrocorticography (ECoG), and (2) to investigate the relationship between rCBF and ECoG influenced by volatile anesthetics. The authors measured rCBF using laser Doppler flowmetry and ECoG simultaneously and continuously from the same cortex during craniotomy, using the specially arranged probe. Patients received intravenous anesthetics with nitrous oxide until craniotomy, and after opening of dura, volatile anesthetic, either isoflurane or sevoflurane, was started and was gradually increased for the measurement. Four of the nine cases (44.4%) of the sevoflurane group s…
Mood, cognitive structuring and medication adherence
2018
A study with a placebo was conducted. Healthy university students were given a placebo and were told to make one pill every day for a week. Participants were informed that the medicine improved mood. The extent to which they conformed to this instruction was treated as an index of compliance. Our results show that for women, but not for men, positive mood and cognitive structuring or negative mood and lack of cognitive structuring significantly predicted participants' compliance. A new model of medication adherence, based on the role of the patient's mood and cognitive structuring processes in decision making is presented in the paper.
Neural correlates of interference inhibition, action withholding and action cancelation in adult ADHD
2011
Attention-Deficit/Hyperactivity Disorder (ADHD) is marked by inhibitory and attentional deficits which can persist into adulthood. Those deficits have been associated with dysfunctional fronto-striatal and fronto-parietal circuits. The present study sought to delineate neural correlates of component specific inhibitory deficits in adult ADHD using functional magnetic resonance imaging (fMRI). 20 adult ADHD patients and 24 matched healthy controls were included. Brain activation was assessed during three stages of behavioral inhibition, i.e. interference inhibition (Simon task), action withholding (Go/no-go task) and action cancelation (Stop-signal task). Behaviorally, ADHD patients were aff…
The latent nature of prolonged grief - A taxometric analysis: Results from a representative population sample
2017
Individuals suffering from prolonged grief disorder (PGD) show severe grief reactions after the death of a significant other, even beyond a period of grieving that is within a person's cultural and religious context. In addition to this core element, PGD can manifest in various ways. Symptoms may include persistent preoccupation, intense emotional pain, or impairment in important life domains. The symptoms, furthermore, have to be of culturally or religiously inappropriate extent or severity, taking into account different norms of grieving. PGD is discussed as a distinct diagnostic category in the revision of the International Classification of Diseases (ICD-11). Nosology of PGD has been hi…
