#1
REVIEW
Annabel Broyd, Ryan P Balzan, Todd S Woodward, Paul Allen
This paper examines the evidence that delusions can be explained within the framework of a neurocognitive model of how the brain assesses certainty. Here, 'certainty' refers to both low-level interpretations of one's environment and high-level (conscious) appraisals of one's beliefs and experiences. A model is proposed explaining how the brain systems responsible for assigning certainty might dysfunction, contributing to the cause and maintenance of delusional beliefs. It is suggested that delusions arise through a combination of perturbed striatal dopamine and aberrant salience as well as cognitive biases such as the tendency to jump to conclusions (JTC) and hypersalience of evidence-hypothesis matches...

OBJECTIVE: This study examined the effects of disaster-related prenatal maternal stress on infant temperament and whether the sex of the infant or the timing of the stressor in pregnancy would moderate the effects. METHODS: Mothers' objective experiences of a sudden-onset flood in Queensland, Australia, their subjective emotional reactions, and cognitive appraisal of the event were assessed. At 6 months postpartum, 121 mothers reported their infant's temperament on the 5 dimensions of the Short Temperament Scale for Infants...

Ingroup perception or the views people with depression have about their group, may influence their vulnerability to social identity threat and lead to enhanced stress reactions and impaired performance. It is unclear how ingroup perception can influence stress appraisals in performance situations among people with a history of depression who are currently in remission. We investigated the impact of ingroup perception on primary stress appraisal, i.e. how threatening a test situation is perceived, as well as on secondary stress appraisal, or perceived coping resources...

Field-based trials are crucial for successfully achieving the goals of plant breeding programs aiming to screen and improve the salt tolerance of crop genotypes. In this study, simulated saline field growing conditions were designed using the subsurface water retention technique (SWRT) and three saline irrigation levels (control, 60, and 120 mM NaCl) to accurately appraise the suitability of a set of agro-physiological parameters including shoot biomass, grain yield, leaf water relations, gas exchange, chlorophyll fluorescence, and ion accumulation as screening criteria to establish the salt tolerance of the salt-tolerant (Sakha 93) and salt-sensitive (Sakha 61) wheat cultivars...

Posttraumatic stress disorder (PTSD) is a clinical condition that occurs after a discrete traumatic event, such as an accident or assault. Research into PTSD has primarily been adult-focused; however, there is a growing body of evidence evaluating the theory and treatment of PTSD in young children. Consequently, cognitive behavior therapy (CBT) interventions for PTSD in youth have been developed that focus on 3 core components of the cognitive model-a disorganized memory of the trauma, maladaptive appraisals of the trauma and its effects (meanings), and dysfunctional coping mechanisms (management)...

Being unemployed and looking for a job has become a source of stress for many people in several European countries. However, little attention has been paid to the impact of this stressful situation on the individuals' psychophysiological stress responses. The aim of this study was to investigate the effect of being an unemployed job seeker on cognitive threat appraisal and cardiac responses to a psychosocial stressor. We exposed a group of unemployed job seekers (N = 42) and a matched group of unemployed non-job seekers (N = 40) to a standardized social stressor in form of job interview, the Trier Social Stress Test...

Patients with hypogonadism are at increased risk of cardiac and metabolic diseases. However, the pathogenesis of increased cardiometabolic risk in patients with hypogonadism is not clear. Oxidative stress plays an important role in the pathogenesis of cardiometabolic diseases. This study aimed to investigate possible differences in oxidative stress conditions between patients with hypogonadism and healthy controls. In this study, 38 male patients with congenital hypogonadotrophic hypogonadism (CHH) (mean age: 21...

In Part 1 of this paper, we discussed emerging evidence suggesting that a general psychopathology or 'p' factor underlying the various forms of psychopathology should be conceptualized in terms of the absence of resilience, that is, the absence of positive reappraisal mechanisms when faced with adversity. These impairments in the capacity for positive reappraisal seem to provide a comprehensive explanation for the association between the p factor and comorbidity, future caseness, and the 'hard-to-reach' character of many patients with severe personality pathology, most notably borderline personality disorder (BPD)...

OBJECTIVE: Previously, we showed that Get Busy Get Better (GBGB), a 10-session multicomponent home-based, behavioral intervention, reduced depressive symptom severity in older African Americans. As appraising the value of life is associated with depressive symptoms, this study examined whether GBGB enhanced positive appraisals of life and if, in turn, this mediated treatment effects on depressive symptoms. METHODS: Data were from a single-blind parallel randomized trial involving 208 African Americans (≥55 years old) with depressive symptoms (Patient Health Questionnaire, PHQ-9 ≥5)...

BACKGROUND: About 25% of the Indian population experience common mental disorders (CMD) but only 15-25% of them receive any mental health care. Stigma, lack of adequate mental health professionals and mental health services account for this treatment gap, which is worse in rural areas. Our project evaluated task shifting and mobile-technology based electronic decision support systems to enhance the ability of primary care health workers to provide evidence-based mental health care for stress, depression, and suicidal risk in 30 remote villages in the state of Andhra Pradesh, India...

Hysteresis losses in magnetic nanoparticles constitute the basis of magnetic hyperthermia for delivering a local thermal stress. Nevertheless, this therapeutic modality is only to be realised through a careful appraisal of the best possible intrinsic and extrinsic conditions to the nanoparticles for which they maximise and preserve their heating capabilities. Low frequency (100 kHz) hysteresis loops accurately probe the dynamical magnetic response of magnetic nanoparticles in a more reliable manner than calorimetry measurements, providing conclusive quantitative data under different experimental conditions...

Stress echocardiography is a widely available, safe, low-cost, versatile imaging modality which is becoming increasingly recognized as a valuable tool in the assessment of patients with native and prosthetic left-sided valvular heart disease. It provides a quantitative assessment to help guide clinical decision-making when discordance exists between symptoms and severity of valve disease. Exercise (treadmill or bicycle) remains the preferred stress modality, but pharmacological augmentation with dobutamine can be used if needed...

Despite decades of empirical literature documenting the harmful effects of frequent, intense, violent, and unresolved interparental conflict on children's adjustment, there is considerable variability in the extent to which marital conflict contributes to the development of children's emotional and behavioral problems. Past research has documented links between properties of interparental conflict itself (e.g., intensity, frequency), children's appraisals of conflict, and children's outcomes, yet less is known about the role of individual and family characteristics in predicting children's conflict appraisals...

BACKGROUND: The quality of parenting, neuroticism, and adult stressful life events are reportedly associated with depressive symptoms. However, previous studies have not examined the complex interaction between these three factors. In this study, we hypothesized that the quality of parenting (care and overprotection) acts on depressive symptoms through 'neuroticism' and the appraisal of adult stressful life events, and this hypothesis was verified by structural equation modeling. METHODS: Four hundred one participants from the general adult population were studied using the following self-administered questionnaire surveys: Patient Health Questionnaire-9 (PHQ-9), Parental Bonding Instrument (PBI), neuroticism subscale of the short version of the Eysenck Personality Questionnaire-revised (EPQ-R), and Life Experiences Survey (LES)...

Major depressive disorder is characterized by emotional dysfunction, but mood states in daily life are not well understood. This study examined complex explanatory models of daily stress and coping mechanisms that trigger and maintain daily negative affect and (lower) positive affect in depression. Sixty-three depressed patients completed perfectionism measures, and then completed daily questionnaires of stress appraisals, coping, and affect for 7 consecutive days. Multilevel structural equation modeling (MSEM) demonstrated that, across many stressors, when the typical individual with depression perceives more criticism than usual, he/she uses more avoidant coping and experiences higher event stress than usual, and this is connected to daily increases in negative affect as well as decreases in positive affect...

Objectives: We examine gender differences in the experienced burden of partner caregivers using the stress-appraisal model. Gender differences can be explained by differences in conditions of burden (primary stressors, help from others, hours of caregiving, and secondary stressors) and how strong their effects are. Method: The data are from the Netherlands' Older Persons and Informal Caregivers Survey-Minimum Data Set (N = 1,611 caregivers). We examine mediation and moderation effects using structural equation modeling...
