Does context matter in misophonia? A multi-method experimental investigation.

Introduction: Misophonia is a recently defined disorder in which certain aversive repetitive sounds and associated stimuli elicit distressing and impairing affective, behavioral, and physiological responses. The responses in misophonia may be stronger when the sound is produced by close friends and family, suggesting that the context in which a triggering cue occurs may have an important role in misophonia. As such, the goal of this study was to test experimentally whether the context of the sound source influences affective and psychophysiological responses to triggering stimuli in misophonia.

Detecting implicit racial bias in provider communication behaviors to reduce disparities in healthcare: Challenges, solutions, and future directions for provider communication training.

Since publication of Unequal Treatment by the Institute of Medicine in 2003, there has been a growing recognition of the role of provider implicit racial bias in patient care. Provider implicit racial bias has been consistently negatively associated with both care satisfaction and provider trust among racial/ethnic minority patients. This suggests provider implicit racial bias likely manifests through their communication behaviors, which in turn may offer a means of addressing racial disparities in healthcare and ultimately in health.

Assessing the coherence of narratives of traumatic events with latent semantic analysis.

Objective: Memories of traumatic events are thought to be less coherent than memories for nontraumatic events, and expressive writing about traumatic events may help create more organized, coherent memories. Investigations of traumatic memories have been hampered by limitations in conceptualizing and measuring memory organization and coherence. The objective of this investigation was to compare the coherence of written narratives of trauma and neutral memories and examine changes in coherence of trauma narratives as a function of repeated expressive writing about the trauma using an atheoretical, computational method for assessing the coherence of text.

Study protocol for investigating physician communication behaviours that link physician implicit racial bias and patient outcomes in Black patients with type 2 diabetes using an exploratory sequential mixed methods design.

Introduction: Patient-physician racial discordance is associated with Black patient reports of dissatisfaction and mistrust, which in turn are associated with poor adherence to treatment recommendations and underutilisation of healthcare. Research further has shown that patient dissatisfaction and mistrust are magnified particularly when physicians hold high levels of implicit racial bias. This suggests that physician implicit racial bias manifests in their communication behaviours during medical interactions.

Resting Heart Rate Variability (HRV) in Adolescents and Young Adults from a Genetically-Informed Perspective.

Reduced heart rate variability (HRV) is associated with cardiac morbidity, mortality, and negative psychopathology. Most research concerning genetic influences on HRV has focused on adult populations, with fewer studies investigating the developmental period of adolescence and emerging adulthood. The current study estimated the genetic and environmental contributions to resting HRV in a sample of twins using various HRV time domain metrics to assess autonomic function across two different time measurement intervals (2.

Effect of expressive and neutral writing on respiratory sinus arrhythmia response over time.

Background And Objectives: Parasympathetic activity, as indexed by respiratory sinus arrhythmia (RSA), underlies key aspects of emotional and cognitive self-regulation. Examining time-varying RSA response during expressive writing about trauma may help inform theory about mechanisms of this intervention. The present study investigated changes in RSA during expressive writing.

Latent Semantic Analysis: A new measure of patient-physician communication.

Rationale: Patient-physician communication plays an essential role in a variety of patient outcomes; however, it is often difficult to operationalize positive patient-physician communication objectively, and the existing evaluation tools are generally time-consuming.

Objective: This study proposes semantic similarity of the patient's and physician's language in a medical interaction as a measure of patient-physician communication. Latent semantic analysis (LSA), a mathematical method for modeling semantic meaning, was employed to assess similarity in language during clinical interactions between physicians and patients.

Alexithymia predicts arousal-based processing deficits and discordance between emotion response systems during emotional imagery.

Alexithymia is believed to involve deficits in emotion processing and imagery ability. Previous findings suggest that it is especially related to deficits in processing the arousal dimension of emotion, and that discordance may exist between self-report and physiological responses to emotional stimuli in alexithymia. The current study used a well-established emotional imagery paradigm to examine emotion processing deficits and discordance in participants (N = 86) selected based on their extreme scores on the Toronto Alexithymia Scale-20.

Acoustic startle and prepulse inhibition predict smoking lapse in posttraumatic stress disorder.

Most smokers who attempt to quit lapse within the first week and are ultimately unsuccessful in their quit attempt. Nicotine withdrawal exacerbates cognitive and attentional problems and may be one factor in smoking relapse. The startle reflex response and prepulse inhibition (PPI) of the response are sensitive to arousal and early attentional dysregulation.

Enhancing the benefits of written emotional disclosure through response training.

Writing about a personal stressful event has been found to have psychological and physical health benefits, especially when physiological response increases during writing. Response training was developed to amplify appropriate physiological reactivity in imagery exposure. The present study examined whether response training enhances the benefits of written emotional disclosure.

Efficacy of a workbook to promote forgiveness: a randomized controlled trial with university students.

Objective: The present study investigated the efficacy of a 6-hour self-directed workbook adapted from the REACH Forgiveness intervention.

Method: Undergraduates (N = 41) were randomly assigned to either an immediate treatment or waitlist control condition. Participants were assessed across 3 time periods using a variety of forgiveness outcome measures.

A test of Spielberger's state-trait theory of anger with adolescents: five hypotheses.

Spielberger's state-trait theory of anger was investigated in adolescents (n = 201, ages 10-18, 53% African American, 47% European American, 48% female) using Deffenbacher's five hypotheses formulated to test the theory in adults. Self-reported experience, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) responses to anger provoking imagery scripts found strong support for the application of this theory to adolescents. Compared with the low trait anger (LTA) group, adolescents with high trait anger (HTA) produced increased HR, SBP, and DBP, and greater self-report of anger to anger imagery (intensity hypothesis) but not greater self-report or cardiovascular reactivity to fear or joy imagery (discrimination hypothesis).

Effects of smoking on the acoustic startle response and prepulse inhibition in smokers with and without posttraumatic stress disorder.

Rationale: Cigarette smokers smoke in part because nicotine helps regulate attention. Prepulse inhibition (PPI) of the startle reflex is a measure of early attentional gating that is reduced in abstinent smokers and in groups with attention regulation difficulties. Attention difficulties are found in people with posttraumatic stress disorder (PTSD).

Efficacy of a cognitive-behavioral treatment for insomnia and nightmares in Afghanistan and Iraq veterans with PTSD.

Objective: Sleep disturbances are a core and salient feature of posttraumatic stress disorder (PTSD). Pilot studies have indicated that combined cognitive-behavioral therapy for insomnia (CBT-I) and imagery rehearsal therapy (IRT) for nightmares improves sleep as well as PTSD symptoms.

Method: The present study randomized 40 combat veterans (mean age 37.

A startling absence of emotion effects: Active attention to the startle probe as a motor task cue appears to eliminate modulation of the startle reflex by valence and arousal.

Research has shown that during emotional imagery, valence and arousal each modulate the startle reflex. Here, two imagery-startle experiments required participants to attend to the startle probe as a simple reaction time cue. In experiment 1, four emotional conditions differing in valence and arousal were examined.

The effect of nicotine and trauma context on acoustic startle in smokers with and without posttraumatic stress disorder.

Rationale: Exaggerated startle response is a prominent feature of posttraumatic stress disorder (PTSD) although results examining differences in the acoustic startle response (ASR) between those with and without PTSD are mixed. One variable that may affect ASR among persons with PTSD is smoking. Individuals with PTSD are more likely to smoke and have greater difficulty quitting smoking.

Effects of posttraumatic stress disorder status and covert hostility on cardiovascular responses to relived anger in women with and without PTSD.

Previous literature has found greater heart rate (HR) and blood pressure (BP) responses during relived anger, and a positive association between covert hostility and relived anger, in male veterans with posttraumatic stress disorder (PTSD). This study investigated hostility and cardiovascular responses to a relived anger task in 120 women (70 with PTSD and 50 without PTSD). Women with PTSD reported greater hostile beliefs and covert hostility than non-PTSD controls, reported greater anger and anxiety during the anger recall task, and had higher resting HR.

Trait anxiety, disgust sensitivity, and the hierarchic structure of fears.

This paper describes an evaluation of Taylor's (1998) hierarchic model of fears and its relationship to trait anxiety and disgust sensitivity (DS). In Study 1 (N=420), a confirmatory factor analysis supported a hierarchic structure of fears. Next, an analysis using structural equation modeling indicated that trait anxiety is associated with claustrophobic and social fears, whereas DS is associated with all four fear subtypes examined (claustrophobic, social, blood-injection-injury and animal).

The effects of cigarette smoking on script-driven imagery in smokers with and without posttraumatic stress disorder.

The study investigated the effects of smoking a nicotinized or denicotinized cigarette on craving, affect and posttraumatic stress disorder (PTSD) symptoms while recalling neutral, stressful and traumatic events in smokers with and without PTSD. Smokers completed laboratory sessions during which they were presented with audiotapes of personalized scripts followed by smoking a cigarette. The effect of the script and cigarette conditions on dependent variables was evaluated.

Psychophysiological responses of female headache sufferers and controls using a picture-viewing paradigm.

Despite the advancement of the biopsychosocial model, the interrelationship between behavioral, emotional, and physiological factors in tension-type headache (TTH) remains unclear. Using a picture-viewing paradigm, the present study investigated differences between females with TTH and controls on physiological reactivity, affective valence and arousal, and oral motor habits. In addition, the concordance between EMG activity and self-reported oral habits (i.

Immediate antecedents of cigarette smoking in smokers with and without posttraumatic stress disorder: a preliminary study.

Using ambulatory methods for 1 day of monitoring, the authors of this study investigated the association between smoking and situational cues in 63 smokers with posttraumatic stress disorder (PTSD) and 32 smokers without PTSD. Generalized estimating equations contrasted 682 smoking and 444 nonsmoking situations by group status. Smoking was strongly related to craving, positive and negative affect, PTSD symptoms, restlessness, and several situational variables among PTSD smokers.

The effects of trauma recall on smoking topography in posttraumatic stress disorder and non-posttraumatic stress disorder trauma survivors.

Smoking topography was measured in trauma survivors with and without posttraumatic stress disorder (PTSD) after recalling trauma-related and neutral experiences. Analysis of covariance was performed on puff topography and mood measures using nicotine dependence scores and current major depressive disorder as covariates. Puff volumes were higher in the PTSD group than in the non-PTSD group.

Reactions to facial expressions: effects of social context and speech anxiety on responses to neutral, anger, and joy expressions.

Male and female participants (n=19) high or low in speech fear viewed pictures of faces posed in anger, neutral, and joyful expressions for 8s each. Zygomaticus major and corrugator supercilii EMG, skin conductance, and heart rate were measured during picture viewing, and subjective ratings were made after each picture. Compared to anger expressions, joy expressions were responded to with greater zygomatic EMG, less corrugator EMG, and greater heart rate and skin conductance.

Ambulatory monitoring and physical health report in Vietnam veterans with and without chronic posttraumatic stress disorder.

This study investigated the associations among PTSD, ambulatory cardiovascular monitoring, and physical health self-reports in 117 male Vietnam combat veterans (61 with PTSD and 56 without PTSD). PTSD was associated with health symptoms and number of current health conditions beyond the influence of several covariates. PTSD was associated with greater systolic blood pressure variability, and an elevated percentage of heart rate and systolic blood pressure readings above baseline.
