Abstract
BACKGROUND The relationships between cognitive and personality profile in teenagers with and without ADHD were assessed. METHOD Two groups of teenagers, one with ADHD (N = 135; mean age = 13.93) and another group without ADHD (N = 199, mean age = 14.29) were evaluated using the K-BIT and 16PF-APQ tests. RESULTS In cognitive variables, the results revealed that the ADHD group returned higher scores in the Matrices subtest and the IQ test. In personality variables, the group with ADHD exhibited higher scores in Tough-Mindedness and lower scores in Self-Control than the group without the disorder. The canonical correlation analysis applied to each group revealed a differing pattern of interrelationships between the cognitive-personality variables in the two groups. In adolescents with ADHD, we observed that higher scores in cognitive variables were associated with a more extroverted personality and less self-control, while in adolescents without ADHD, higher scores in cognitive variables were associated with less tough-mindedness and lower levels of self-control. CONCLUSIONS The cognitive and personality variables of adolescents with and without ADHD differ. These results will be useful for establishing a cognitive and personality profile for this section of the population. The educational implications of the study are under discussion.

Emotional stability is related to 2D:4D and social desirability in women: Possible implications on subjective well-being and psychopathology. PLoS One 2021; 16:e0248368. [PMID: 33690629 PMCID: PMC7942991 DOI: 10.1371/journal.pone.0248368] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Accepted: 02/23/2021] [Indexed: 01/07/2023] Open
Abstract
Emotional stability-Neuroticism is a complex construct influenced by genetics and environmental factors. Women tend to exhibit higher neuroticism scores than men, which may be associated with an increased risk of suffering from some common mental conditions. Some authors have pointed out the influence of sex hormones, since they induce sexual differentiation of the brain that can lead to sex-specific behaviors. 2D:4D digit ratio is commonly used as a marker of prenatal sex hormones. In this study we analyzed whether there was an association between 2D:4D and personality measured through the BFQ in a homogeneous sample of 101 young women college students. We found a positive association between 2D:4D and emotional stability, as well as with its subdimensions emotion control and impulse control. This association could be quadratic and nonlinear. However, no association was found with the other four dimensions. We also measured anxiety, depression and global life satisfaction, variables related to neuroticism. We observed that emotional stability is positively associated to social desirability and global life satisfaction, and negatively related to anxiety and depression. On the other hand, we did not find any association between 2D:4D and anxiety, depression, and global life satisfaction. These results can be linked to other aspects such as subjective well-being and psychopathological symptoms. This study may help to better understand how these constructs are related and could lead to future projects to elucidated how these variables influence personality.

Abstract
Objective: The study examined how the interplay between maternal ADHD symptoms and maternal inhibitory control and child ADHD is related to parenting behaviors. Method: The sample included 141 mothers and their 8- to 12-year-old children, 61 children with ADHD and 80 without. Parenting was measured using self-reports (i.e., overreactive and lax parenting) and observation (i.e., negative and supportive parenting). Maternal inhibitory control was measured using a neurocognitive task. Hierarchical multiple regressions were conducted to predict parenting, controlling for child sex, conduct behaviors, and parenting distress. Results: Interactions between maternal ADHD symptoms and maternal inhibitory control suggested that hyperactive-impulsive symptoms were linked to parenting negativity only when inhibitory control was low, and maternal inattention symptoms were related to lax parenting only when maternal inhibitory control was high or when children did not have ADHD. Conclusion: Results indicate the importance of maternal regulation processes in the mechanisms linking maternal ADHD with parenting.

Temperamental risk factors in young adults with ADHD symptoms. CURRENT PROBLEMS OF PSYCHIATRY 2021.

Abstract
Abstract
Introduction: In recent years, numerous studies have focused on the analysis of the primary mechanisms and forms of therapy in children and adolescents with attention deficit hyperactivity disorder (ADHD). The analysis of such topics among similarly diagnosed young adults is only beginning to gain popularity. The present article attempts to answer the question of whether the level of individual temperament traits will predict an increase in the severity of ADHD symptoms in young adults.
Materials and methods: The questionnaire study involved 111 young adults aged from 18 to 28 (M= 23; SD= 2.12; 70 women and 41 men). Fifty-one people were included in the clinical group, and sixty were qualified for the control one. The participants of the study completed a health questionnaire and a structured diagnostic interview on ADHD symptoms in adults (DIVA 2.0) and a questionnaire for the diagnosis of basic, biologically determined dimensions of human personality (FCZ-KT (R)).
Results: The results indicate a significant role of four temperament traits that may be considered as specific risk factors for the aggravation of ADHD symptoms. These include briskness, rhythm, endurance and activity.
Conclusions: In Strelau’s Regulatory Theory of Temperament, the variability of temperament traits (in the Polish population) is attributed in 44% to genetic factors. The remaining 56% indicate non-genetic factors. The obtained results may indicate which factors are important in therapeutic work both in the group of young adults with ADHD symptoms, and may also constitute a source of information for parents or teachers regarding younger children with these symptoms.

Heterogeneity and Subtyping in Attention-Deficit/Hyperactivity Disorder-Considerations for Emerging Research Using Person-Centered Computational Approaches. Biol Psychiatry 2020; 88:103-110. [PMID: 31924323 PMCID: PMC7210094 DOI: 10.1016/j.biopsych.2019.11.002] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Revised: 11/01/2019] [Accepted: 11/02/2019] [Indexed: 11/22/2022]
Abstract
Few if any experts believe that existing psychiatric diagnostic categories included in DSM and ICD are actually discrete disease entities. Attention-deficit/hyperactivity disorder (ADHD) is emblematic of the problems in the existing psychiatric classification system. ADHD symptoms reliably cluster into two correlated dimensions in factor analysis. However, children with ADHD vary considerably in their symptom profiles, symptom trajectories, clinical outcomes, and biological and psychological correlates. Thus, the field has sought alternative approaches that harness the dimensions of emotional, cognitive, and behavioral functioning that underlie ADHD and other existing psychiatric categories to create informative phenotypes that improve clinical prediction and clarify etiology. Within ADHD, cognitive (neuropsychological) and temperament/personality features have received considerable attention. In some cases, subphenotypes based on these features appear to improve on existing classifications and could eventually be translated into clinical practice. This review summarizes findings from subphenotyping efforts in ADHD that use cognitive, emotion-related, and other features to highlight major considerations for research applying person-oriented approaches to inform an improved psychiatric nosology. Considerations related to feature selection, validation of newly proposed divisions, defining populations of interest, and incorporating a developmental perspective are discussed.

Abstract
Objective: We computationally analyze the language of social media users diagnosed with ADHD to understand what they talk about, and how their language is correlated with users' characteristics such as personality and temporal orientation. Method: We analyzed approximately 1.3 million tweets written by 1,399 Twitter users with self-reported diagnoses of ADHD, comparing their posts with those used by a control set matched by age, gender, and period of activity. Results: Users with ADHD are found to be less agreeable, more open, to post more often, and to use more negations, hedging, and swear words. Posts are suggestive of themes of emotional dysregulation, self-criticism, substance abuse, and exhaustion. A machine learning model can predict which of these Twitter users has ADHD with an out-of-sample AUC of .836. Conclusion: Based on this emerging technology, conjectures of future uses of social media by researchers and clinicians to better understand the naturalistic manifestations and sequelae of ADHD.

J Med Internet Res 2019; 21:e11837. [PMID: 31025955 PMCID: PMC6658222 DOI: 10.2196/11837] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Revised: 12/19/2018] [Accepted: 02/03/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND There are many empirical studies that demonstrate the associations between problematic internet use, psychopathological symptoms, and personality traits. However, complex models are scarce. OBJECTIVE The aim of this study was to build and test a mediation model based on problematic internet use, psychopathological symptoms, and personality traits. METHODS Data were collected from a medical addiction center (43 internet addicts) and internet cafés (222 customers) in Beijing (mean age 22.45, SD 4.96 years; 239/265, 90.2% males). Path analysis was applied to test the mediation models using structural equation modeling. RESULTS Based on the preliminary analyses (correlations and linear regression), two different models were built. In the first model, low conscientiousness and depression had a direct significant influence on problematic internet use. The indirect effect of conscientiousness-via depression-was nonsignificant. Emotional stability only affected problematic internet use indirectly, via depressive symptoms. In the second model, low conscientiousness also had a direct influence on problematic internet use, whereas the indirect path via the Global Severity Index was again nonsignificant. Emotional stability impacted problematic internet use indirectly via the Global Severity Index, whereas it had no direct effect on it, as in the first model. CONCLUSIONS Personality traits (ie, conscientiousness as a protective factor and neuroticism as a risk factor) play a significant role in problematic internet use, both directly and indirectly (via distress level).

Abstract
The National Institute of Mental Health launched the Research Domain Criteria (RDoC) initiative to better understand dimensions of behavior and identify targets for treatment. Examining dimensions across psychiatric illnesses has proven challenging, as reliable behavioral paradigms that are known to engage specific neural circuits and translate across diagnostic populations are scarce. Delay discounting paradigms seem to be an exception: they are useful for understanding links between neural systems and behavior in healthy individuals, with potential for assessing how these mechanisms go awry in psychiatric illnesses. This article reviews relevant literature on delay discounting (or the rate at which the value of a reward decreases as the delay to receipt increases) in humans, including methods for examining it, its putative neural mechanisms, and its application in psychiatric research. There exist rigorous and reproducible paradigms to evaluate delay discounting, standard methods for calculating discount rate, and known neural systems probed by these paradigms. Abnormalities in discounting have been associated with psychopathology ranging from addiction (with steep discount rates indicating relative preference for immediate rewards) to anorexia nervosa (with shallow discount rates indicating preference for future rewards). The latest research suggests that delay discounting can be manipulated in the laboratory. Extensively studied in cognitive neuroscience, delay discounting assesses a dimension of behavior that is important for decision-making and is linked to neural substrates and to psychopathology. The question now is whether manipulating delay discounting can yield clinically significant changes in behavior that promote health. If so, then delay discounting could deliver on the RDoC promise.
