Effects of single trial of heart-rate biofeedback during ramp bicycling exercise

We examined whether a single trial of heart-rate biofeedback was effective to attenuate heart-rate responses during ramp exercise despite a lack of biofeedback conditioning. 35 healthy women exercised in two trials while they tried to attenuate their heart rate by watching biofeedback signals or they only exercised without biofeedback signals (Control trial). 17 subjects were able to attenuate the heart rate during Biofeedback trial (Can group) whereas the remaining subjects were not (Cannot group). In the Can group, the magnitude of heart-rate attenuation in all exercise time was equivalent to 11+/-3% of the preexercise heart rate. Since the heart-rate reduction was similar to that achieved after the heart-rate biofeedback conditioning in previous studies, it is likely that the single trial of heart-rate biofeedback was effective for almost half the subjects to attenuate the heart-rate responses during ramp exercise.     

Adaptive automation, trust, and self-confidence in fault management of time-critical tasks

An experiment on adaptive automation is described. Reliability of automated fault diagnosis, mode of fault management (manual vs. automated), and fault dynamics affect variables including root mean square error, avoidance of accidents and false shutdowns, subjective trust in the system, and operator self-confidence. Results are discussed in relation to levels of automation, models of trust and self-confidence, and theories of human-machine function allocation. Trust in automation but not self-confidence was strongly affected by automation reliability. Operators controlled a continuous process with difficulty only while performing fault management but could prevent unnecessary shutdowns. Final authority for decisions and action must be allocated to automation in time-critical situations.     

Self-compassion and responses to negative social feedback: The role of fronto-amygdala circuit connectivity

ABSTRACT

Self-compassion has been shown to have significant relationships with psychological health and well-being. Despite the increasing growth of research on the topic, no studies to date have investigated how self-compassion relates to neural responses to threats to the self. To investigate whether self-compassion relates to threat-regulatory mechanisms at the neural level of analysis, we conducted a functional MRI study in a sample of college-aged students. We hypothesized that self-compassion would relate to greater negative connectivity between the ventromedial prefrontal cortex (VMPFC) and amygdala during a social feedback task. Interestingly, we found a negative correlation between self-compassion and VMPFC-amygdala functional connectivity as predicted; however, this seemed to be due to low levels of self-compassion relating to greater positive connectivity in this circuit (rather than high levels of self-compassion relating to more negative connectivity). We also found significant relationships with multiple subcomponents of self-compassion (Common Humanity, Self-Judgment). These results shed light on how self-compassion might affect neural responses to threat and informs our understanding of the basic psychological regulatory mechanisms linking a lack of self-compassion with poor mental health.

Personality Dysfunction and the Management of Chronic Medical Illness: A Community Health Sample

The purpose of this study was to determine the influence of personality disorders on perceived health status, self-efficacy for management of the chronic illness, and physician perception of patient health. A total of 607 patients with self-identified chronicillness(es) volunteered to participate in the study. Out of this sample, 147 had collaborative physician data indicating a chronic illness. The final sample was 143 due to incomplete data. Results suggested that maladaptive personality characteristics, as measured by the Short-Form of the Coolidge Axis II Inventory (SCATI), were related to a number of important factors that influence self-management of chronic illnesses. When the personality constellations were broken into 3 groups (normal, subclinical, and clinical) significant differences were found on the 3 groups of dependent variables (Subjective Health, Self-Efficacy, Physician Appraisal) for the different personality disorders. These data provide useful information on several factors that influence effective disease management. Clinical implications and directions for future research are provided.     

Personality Disorders in Older Adult Inpatients with Chronic Mental Illness

It has been hypothesized that some types of personality disorders tend to remit with age whereas others may become more prominent. The present study determined the prevalence and nature of 13 personality disorders with a self-report inventory (Coolidge Axis II Inventory) in an older group of chronically mentally ill inpatients (N = 30, mean age = 63 years) and a younger group of similar patients (N = 30, mean age = 39 years). All patients met DSM-IV criteria for either Schizophrenia, Schizoaffective Disorder, Bipolar Disorder, or recurrent severe Major Depression with psychotic features. The prevalence rate of personality disorders was high for both groups: 58% for the older sample and 66% for the younger group. The younger group was more likely to be diagnosed Antisocial, Borderline, Passive-Aggressive, Sadistic, and Schizotypal, but the groups were not different in the rates of Obsessive-Compulsive Disorder. This study supports the hypothesis that some personality disorders remit with age. However, no evidence was found to suggest that other personality disorders become more prominent in older adult psychiatric populations. Suggestions for future research are offered.     

Mental Health Inventory for Infants: Scale Development and Japanese Infants’ Characteristics

Early detection and treatment promote positive outcomes in mental health problems among infants. This study developed a simple and reliable screening inventory for infants’ mental health. Participants were 579 primary caregivers who had Japanese infants aged 2–6 years. Participants evaluated their children using the Mental Health Inventory for Infants (MHII; developed in this study), which contains 24 items. Exploratory factorial analysis identified the MHII factor structure; confirmatory factorial analysis examined its factorial validity. Internal consistency and criterion-related validity were also examined. Irritability (8 items), somatic symptoms (6 items), and signs of insecurity (4 items) were identified as factors in the MHII; each of these factors measures a critical aspect of infants’ mental health. The MHII’s internal consistency and scale homogeneity were acceptable; its criterion-related validity was supported. In this study, male infants exhibited greater irritability and less insecurity than females. The present results support the MHII’s reliability and validity; additionally, they indicate that caregivers may use the MHII to quickly screen for three critical aspects of infants’ mental health. We expect that the MHII will be used for early detection of mental health difficulties in infants to facilitate treatment.
