Symptom awareness and blood glucose estimation in diabetic adults

Self-regulation of diabetes depends in part on common-sense models of symptoms and blood glucose fluctuations. Symptom perception and subjective estimation of blood glucose were studied in 52 adult, difficult-to-control, non-insulin-dependent diabetics using a structured interview and laboratory blood-glucose measurement. Most patients believed they could detect hyperglycemia. Symptoms linked by patients to hyperglycemic and hypoglycemic episodes did overlap with symptoms traditionally associated with those states. Some patients may experience dysphoria during glycemic swings to which multiple symptom labels are applicable, although prominent exceptions and idiosyncratic symptoms were evident. Estimation of current blood glucose using an ordinal scale suggested some capacity for discriminating blood glucose levels. Numerical estimates of Chemstrip values were correlated with actual values, but far too inaccurately for purposes of self-regulation. Research is needed to clarify whether subjective symptom perception and blood glucose estimation helps or hinders self-regulation of diabetes.     

Individual differences in adolescents' sympathetic and parasympathetic functioning moderate associations between family environment and psychosocial adjustment

The present study tested whether individual differences in autonomic nervous system functioning interact with environmental risk factors to predict adolescents' psychosocial functioning. The authors assessed skin conductance and respiratory sinus arrhythmia at rest and during laboratory stressors in 110 14-year-olds. Subsequently, adolescents and their mothers provided both questionnaire and daily diary data (over 10 days) on emotional and interpersonal functioning. The authors found stronger associations between environmental risk factors (having a single-mother household or a mother with high internalizing problems) and psychosocial outcomes (externalizing problems, daily negative affect, and daily interaction quality) among youths with specific patterns of tonic and stress-induced sympathetic and parasympathetic nervous system activity, but the pattern of moderating effects differed between boys and girls. The findings support the notion that individual differences in autonomic functioning index variation in youth's susceptibility to environmental risk factors.     

Prenatal auditory experience and its sequelae

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we present computational tests of the hypothesis that this early exposure to severely degraded auditory inputs serves an adaptive purpose—it may induce the neural development of extended temporal integration. Such integration can facilitate the detection of information carried by low-frequency variations in the auditory signal, including emotional or other prosodic content. To test this prediction, we characterized the impact of several training regimens, biomimetic and otherwise, on a computational model system trained and tested on the task of emotion recognition. We find that training with an auditory trajectory recapitulating that of a neurotypical infant in the pre-to-postnatal period results in temporally extended receptive field structures and yields the best subsequent accuracy and generalization performance on the task of emotion recognition. This strongly suggests that the progression from low-pass-filtered to full-frequency inputs is likely to be an adaptive feature of our development, conferring significant benefits to later auditory processing abilities relying on temporally extended analyses. Additionally, this finding can help explain some of the auditory impairments associated with preterm births, suggests guidelines for the design of auditory environments in neonatal care units, and points to enhanced training procedures for computational models.     

The short-form Buss-Perry Aggression Questionnaire (BPAQ-SF): a validation study with federal offenders

The 12-item short form of the Buss-Perry Aggression Questionnaire (BPAQ-SF) was originally developed by Bryant and Smith (2001) and modified and confirmed using confirmatory factor analysis with mentally ill offenders by Diamond, Wang, and Buffington-Vollum (2005). In the current study, construct validity of the BPAQ-SF was assessed with a sample of 1,181 male and 435 female general population federal offenders. Confirmatory factor analysis supported the four-factor structure. Tests confirmed factorial invariance across gender for all loadings and covariances. Reliabilities were found to be adequate and comparable to those found in the studies cited above. Concurrent validity was supported by high correlations between the subscales of the BPAQ-SF and several relevant subscales on the Personality Assessment Inventory (PAI). In addition, those offenders with prior history of violence, head injuries, childhood abuse, residential treatment, custody, or foster care as a child had higher scores on the BPAQ subscales.

Transference Focused Psychotherapy for Patients with Comorbid Narcissistic and Borderline Personality Disorder

Clinical experience involving the treatment of patients with comorbid borderline and narcissistic personality disorders suggests that this patient population is among the more difficult to treat within the personality disorder spectrum. In this article, we present refinements of Transference Focused Psychotherapy (TFP) based on our clinical experience with and research data on patients with comorbid narcissistic personality disorder/borderline personality disorder (NPD/BPD). We briefly review object relations formulations of severe narcissistic pathology, as well as recent research in attachment and the allied concept of mentalization, which have provided a new lens through which to view narcissistic disorders. The research findings from two randomized clinical trials demonstrating the efficacy and effectiveness of TFP are presented. The data from the two Randomized Clinical Trials (RCT) allowed for the study of the characteristics of the subgroup of borderline personality disorder patients who have comorbid NPD/BPD. Findings on comorbidity, attachment status, capacity for mentalization, and level of personality organization of borderline patients with comorbid NPD/BPD, compared with borderline patients without comorbid narcissistic pathology (BPD), are presented. Clinical implications of the observed group differences are discussed, with a focus on refinements in the technique of TFP. Clinical case material is presented to illustrate the specific challenges posed by narcissistic patients to carrying out TFP in each phase of treatment.     

Emotion Regulation Across the Life Span: An Integrative Perspective Emphasizing Self-Regulation,Positive Affect,and Dyadic Processes

In this commentary, we build upon the papers featured in this 2-part special issue to advance an integrative perspective on emotion regulation that emphasizes the developmentally specific goal-contexts of emotional phenomena. We highlight the importance of (1) multilevel longitudinal investigations of interactions among biological, affective, cognitive, and behavioral processes with respect to emotion regulation; (2) the integration of emotion-regulation processes with self-regulatory processes across the life course; (3) the dynamic relationship between positive and negative affect and their respective influence on regulatory processes; and (4) greater consideration of the dyadic context of emotion-regulation processes. From this perspective, the optimal developmental outcome with respect to emotion regulation is not affective homeostasis, but rather a dynamic flexibility in emotional experience, the ability to pursue and prioritize different goals, and the capacity to selectively and proactively mobilize emotions and cognitions in the service of context-specific and developmentally specific goals.     

Integrating Diverse Developmental Perspectives on Emotion Regulation

Emotion regulation has been studied in diverse ways within different subdisciplines of psychology—most notably social development, personality and individual differences, social psychophysiology, interpersonal relationships, and stress and coping. The goal of this Special Issue is to demonstrate the value of integrating these diverse approaches for building multilevel, lifespan models of emotion regulation. We review each of the contributions to this special issue, highlighting recurring themes and previewing our own perspective on directions for future theory and research.
