Use of the Brazilian version of the Interpersonal Negotiation Strategies Interview (INSI) in a child and adolescent sample: a pilot study.

Introduction: Interpersonal negotiation skills (INS) comprise actions used to solve social situations between interacting individuals involving different needs or desires. These abilities are part of one's social competence and may be impaired in some psychiatric conditions. There are few validated psychometric tools for measuring INS in the literature.

Disregarding Impairment in ADHD Diagnosis Inflates Its Prevalence.

fifth edition () diagnostic criteria for attention-deficit hyperactivity disorder (ADHD) has reemphasized impairment although many studies have demonstrated that such approach may inflate prevalence rates. However, there is no consensus on how impairment should be measured and a myriad of approaches in different studies make comparisons difficult. To investigate whether impairment measured using a previous validate quantitative measure modifies prevalence rates in a sample of Brazilian children and adolescents.

Mind-wandering, depression, anxiety and ADHD: Disentangling the relationship.

Background: Mind Wandering (MW) has been associated with ADHD in a very small number of studies with adults and children. However, anxiety and depression have also been associated with MW and both are often comorbid with ADHD. The aim of this study was to investigate the role of anxiety and depression in MW in patients with ADHD.

Impulsivity as an Endophenotype in ADHD: Negative Findings.

Impulsivity has a strong genetic component and is considered an endophenotype in many psychiatric disorders. Impulsivity in adult ADHD has become a focus of interest more recently because of its suggested prominence in this age. This study aimed to access self-reported impulsivity levels in biological parents of ADHD offspring, according to their status: non-ADHD (controls), remitted, nonremitted.

Transcultural adaptation to Portuguese of the Mind Excessively Wandering Scale (MEWS) for evaluation of thought activity.

Introduction: The concept of mind wandering refers to periods during which attention and content of thoughts depart from the original idea or activity being performed. The phenomenon occurs commonly in the general population and the Mind Wandering Excessively Scale (MEWS) evaluates its frequency, intensity and related negative outcomes.

Objective: To describe the cross-cultural adaptation of the MEWS.

Multilevel analysis of ADHD, anxiety and depression symptoms aggregation in families.

A strong genetic role in the etiology of attention-deficit hyperactivity disorder (ADHD) has been demonstrated by several studies using different methodologies. Shortcomings of genetic studies often include the lack of golden standard practices for diagnosis for ADHD, the use of categorical instead of a dimensional approach, and the disregard for assortative mating phenomenon in parents. The current study aimed to overcome these shortcomings and analyze data through a novel statistical approach, using multilevel analyses with Bayesian procedures and a specific mathematical model, which takes into account data with an elevated number of zero responses (expected in samples with few or no ADHD symptoms).

Is ADHD a risk factor independent of conduct disorder for illicit substance use? A meta-analysis and metaregression investigation.

Objective: To investigate meta-analytically if the association between ADHD and illicit substance use (ISU) is maintained when controlling for conduct disorder/oppositional-defiant disorder (CD/ODD).

Method: A systematic literature review was conducted through Medline from 1980 to 2008. Data extracted and selections made by one author were reviewed by another.
