The article draws primarily from the behavioral findings (mainly psychiatric and psychological observations) and points out the important relationships between attention-deficit/hyperactivity disorder (ADHD) symptoms and time orientation. Specifically, the authors argue that there is a significant overlap between the symptoms of ADHD and Present Hedonism. Present Hedonism is defined by Zimbardo's time perspective theory and assessed by Zimbardo Time Perspective Inventory. Developmental data on Present Hedonism of males and females in the Czech population sample (N=2201) are also presented...

Boredom proneness has been linked to various forms of cognitive and affective dysregulation including poor self-control and mind-wandering (MW), as well as depression and aggression. As such, understanding boredom and the associated cognitive and affective components of the experience, represents an important first step in combatting the consequences of boredom for psychological well-being. We surveyed 1928 undergraduate students on measures of boredom proneness, self-control, MW, depression and aggression to investigate how these constructs were related...

Social conflict is a predominant stressor in humans and is associated with increased risk for developing psychological illnesses including depression and anxiety. Overwhelmingly, more women suffer from these disorders, which may be due to increased stress sensitivity. Like humans, rodents experience a myriad of physiological and behavioral sequelae due to prolonged stress exposure. Although the motivation for social conflict may differ between humans and rodents, female rodents may provide an opportunity to explore the underlying mechanisms by which stress confers risk for psychopathology in women...

Previous research has demonstrated that veterans with posttraumatic stress disorder (PTSD) are at higher risk for aggression, hostility, and anger, potentially leading to problems with the law or disciplinary action while in the military. There have been calls for increased consideration of the unique aspects of the judicial system in legal matters with veterans involved. The bulk of the research so far has considered the link between PTSD, traumatic brain injury (TBI), and combat exposure, but little is known about the potential role of chronic pain and Military Sexual Trauma (MST) in a veteran's experience of anger, aggression, and discipline while in the military and legal concerns...

There is an increasing interest in psychological research on shame experiences and their associations with other aspects of psychological functioning and well-being, as well as with possible maladaptive outcomes. In an attempt to confirm and extend previous knowledge on this topic, we investigated the nomological network of shame experiences in a large community sample (N = 380; 66.1% females), adopting a multidimensional conceptualization of shame. Females reported higher levels of shame (in particular, bodily and behavioral shame), guilt, psychological distress, emotional reappraisal, and hostility...

Individuals are not merely subject to their social environments; they choose and create them, through a process called social environment (or social niche) construction. When genotypes differ in social environment-constructing behaviors, different genotypes are expected to experience different social environments. As social experience often affects behavioral development, quantitative genetics and psychology theories predict that genetic variation in social environment construction should have an important role in determining phenotypic variation; however, this hypothesis has not been tested directly...

Objective: Traumatic stressors and other forms of adversities, especially when experienced during childhood, shape aggressive behavior. Effects of differential dimensions of impulsivity on the relationship between psychological trauma, reactive aggression (defensive survival response to threat), and appetitive aggression (the pleasure of attacking and fighting) have not yet been assessed. Method: Using structural equation modeling, we sought to uncover precursors of reactive and appetitive aggression investigating a sample of 94 adult individuals with refugee status...

The gut microbiome is a diverse, host-specific, and symbiotic bacterial environment that is critical for mammalian survival and exerts a surprising yet powerful influence on brain and behavior. Gut dysbiosis has been linked to a wide range of physical and psychological disorders, including autism spectrum disorders and anxiety, as well as autoimmune and inflammatory disorders. A wealth of information on the effects of dysbiosis on anxiety and depression has been reported in laboratory model systems (e.g., germ-free mice); however, the effects of microbiome disruption on social behaviors (e...

Parents interact with their environment in important ways that may impact their ability to parent their children positively. The current study uses data from the age 3 wave of the Fragile Families and Child Wellbeing study to investigate whether neighborhood processes and community participation relate to internal control, and whether these three variables are associated with child maltreatment behaviors. Using structural equation modeling, the direct and indirect effects of the environment (neighborhood disorder, social control, and social cohesion) and community participation on child maltreatment are tested...

PURPOSE: The objective of this study was to investigate the psychosocial factors associated with violence by women against their children, using a household survey. METHODS: Households in two neighborhoods in Juiz de Fora, Brazil, with different socioeconomic profiles, were selected through probability sampling and surveyed. A total of 446 women with children up to 18 years of age were interviewed. A sociodemographic questionnaire, the CTSPC (Parent-Child Conflict Tactics Scales), the CES-D (Center for Epidemiologic Studies Depression Scale) and the AUDIT (Alcohol Use Disorders Identification Test) were applied...

BACKGROUND: Prenatal maternal obesity has been linked to adverse childhood neuropsychiatric outcomes, including increased symptoms of attention deficit hyperactivity disorder (ADHD), internalizing and externalizing problems, affective disorders and neurodevelopmental problems but few studies have studied neuropsychiatric outcomes among offspring born to very severely obese women or assessed potential familial confounding by maternal psychological distress. METHOD: We evaluated neuropsychiatric symptoms in 112 children aged 3-5 years whose mothers had participated in a longitudinal study of obesity in pregnancy (50 very severe obesity, BMI ⩾40 kg/m2, obese class III and 62 lean, BMI 18...

Caregivers of individuals with intellectual and developmental disabilities (IDD) often end up having their medical and psychological well-being compromised due to the stressful nature of caregiving, especially when those in their care engage in aggressive behavior. In this study, we provided caregivers with mindfulness-based training to enable them to better manage their psychological well-being and, through this, to also enhance specific indices of quality of life of the individuals in their care. Thus, the aim of the present study was to evaluate in a randomized controlled trial (RCT) the comparative effectiveness of Mindfulness-Based Positive Behavior Support (MBPBS) and Training-as-Usual (TAU) for caregivers in a congregate care facility for individuals with severe and profound IDD...

Fournier's gangrene is a severe polymicrobial necrotizing fasciitis of the perineal, genital, or perianal regions. The classic presentation is severe pain and swelling with systemic signs. Crepitus and cutaneous necrosis are often seen. Characteristic CT findings include subcutaneous gas and inflammatory stranding. Unless treated aggressively, patients can rapidly become septic and die. Factitious Disorder is the falsification of one's own of medical or psychological signs and symptoms. Many deceptive methods have been described, from falsely reporting physical or psychological symptoms, to manipulating lab tests, or even injecting or ingesting foreign substances in order to induce illness...

Most patients with dementia have some behavioural and psychological symptoms. While aggression and agitation are easily recognised, symptoms such as apathy may be overlooked. Behavioural and psychological symptoms should be managed without drugs whenever possible. Although there is little evidence to support their use, antipsychotic drugs are often prescribed to people with dementia. Before prescribing it is important to exclude other causes of altered behaviour, such as pain or infection. Some symptoms may be artefacts of memory loss rather than psychosis...

Post-traumatic stress disorder (PTSD), a condition that disproportionately affects military veterans, is associated with heightened rates of aggression and suicide. Although experience with firearms is common among this population, virtually nothing is known regarding who is more likely to own a firearm and whether firearm ownership is differentially associated with psychological and behavioral risk factors among veterans with PTSD. Of 465 veterans (79% male) entering PTSD treatment, 28% owned a firearm (median number of firearms among owners = 3, range = 1-40)...

Hypersexuality, or extreme normophilic sexual urges and behaviors, is a controversial construct that was recently considered as a candidate disorder for the DSM-5 and was rejected. It was also rejected for inclusion in Section III (Conditions for Further Study). Nonetheless, it has been found to be an important predictor of recidivism among sex offenders, and it continues to be discussed widely in the literature. In the present study, we investigated the developmental roots of this construct in a sample of 529 adult male sexual offenders, who were administered the Multidimensional Assessment of Sex and Aggression...

BACKGROUND: Adolescence is a stressful period where important biological, psychological and social changes occur. Adolescents are particularly vulnerable during this developmental period and can use various strategies to deal with daily stress, such as substance use or externalizing behaviors. In previous studies, stress in adolescents with externalizing behaviors was often linked to ineffective cognitive coping strategies (i.e., constructive thinking) and overlooking the biological aspects involved in stress management such as neuroendocrine regulation...
