Borderline personality disorder and emotion regulation: insights from the Polyvagal Theory

The current study provides the first published evidence that the parasympathetic component of the autonomic nervous system differentiates the response profiles between individuals diagnosed with borderline personality disorder (BPD) and controls. Respiratory sinus arrhythmia (RSA), a non-invasive marker of the influence of the myelinated vagal fibers on the heart, and heart period were collected during the presentation of film clips of varying emotional content. The BPD and control groups had similar initial levels of RSA and heart period. However, during the experiment the groups exhibited contrasting trajectories, with the BPD group decreasing RSA and heart period and the control group increasing RSA and heart period. By the end of the experiment, the groups differ significantly on both RSA and heart period. The correlation between the changes in RSA and heart period was significant only for the control group, suggesting that vagal mechanisms mediated the heart period responses only in the control group. The findings were consistent with the Polyvagal Theory [Porges, S. W. (1995). Orienting in a defensive world: Mammalian modifications of our evolutionary heritage: A Polyvagal Theory. Psychophysiology, 32, 301-318; Porges, S. W. (2001). The Polyvagal Theory: Phylogenetic substrates of a social nervous system. International Journal of Psychophysiology, 42, 123-146; Porges, S. W. (2003). Social engagement and attachment: A phylogenetic perspective. Annals of the New York Academy of Sciences, 1008, 31-47.], illustrating different adaptive shifts in autonomic state throughout the course of the experiment. The BPD group ended in a physiological state that supports the mobilization behaviors of fight and flight, while the control group ended in a physiological state that supports social engagement behaviors. These finding are consistent with other published studies demonstrating atypical vagal regulation of the heart with other psychiatric disorders.     

Jung's dissociable psyche and the ec-static self

Abstract :  Much of Jung's later work assumes that the self is an  a priori  phenomenon in which centripetal dynamics dominate. There is, however, another current in Jung's writings which recognizes the self to be an emergent phenomenon. This view is increasingly prevalent in post-Jungian discourse, and Louis Zinkin's exploration of a post-Jungian-constructivist model of the self can be seen as part of this tendency.
My paper privileges an emergent understanding of the self by focusing on the 'unravelling', 'de-centring', centrifugal experiences of otherness in the psyche. It offers a post-Jungian reading of a number of writers who have been influenced by the psychoanalyst Jean Laplanche and proposes a model of the self which focuses on our fantasies, terrors and longings about coming undone and bringing others undone.
This model is then linked to Judith Butler's understanding of the self as an ec-static phenomenon, in which the self is, of necessity, outside itself, such that 'there is no final moment in which my return to myself takes place'. I suggest that Jung's early clinical researches into the dissociability of the psyche and the clinical tools which he developed as a result of this work are especially suitable for engaging with these emergent, centrifugal dynamics.     

Religious Perfectionism Scale Among Believers of Multiple Faiths in China: Development and Psychometric Analysis

In China, many people are converting to various world religions. Nonetheless, religious adherence for them, as with many people, can still function as a double-edged sword with regards to mental health. In particular, religious perfection can become either a healthy commitment or a rigid outlook that leads to distress. Thus, we developed the Religious Perfectionism Scale (RPS) from Chinese religious believers. In the first phase (N = 171), we collected qualitative data through an open-question survey from different religious groups (i.e., Buddhism, Protestantism, and Islam). Then, we developed an item pool based on themes that emerged from these qualitative data. In the second phase, participants (N = 1055) were randomly split into two subsamples. Exploratory factor analyses were performed on the first subsample (N = 519) to select the scale items. The nine-item RPS subsequently includes two dimensions—Zealous Religious Dedication and Religious Self-Criticism. Confirmatory factor analyses (CFA) were performed on the second subsample (N = 536) to cross-validate the factor structure. Results indicate that the internal consistency reliability for the RPS subscale scores was all adequate. Furthermore, the construct validity of the RPS was supported through its correlations with measures of perfectionism perceived to have come from God (or a higher power), psychological indicators, and a personality variable (i.e., discipline) in expected directions. Results of the psychometric evaluations of this newly developed scale suggest that the RPS is a promising measure in that it can facilitate future research that leads to a more comprehensive understanding of the impact of religious perfectionism on psychological well-being.

     

The impact of self-efficacy on behavior change and weight change among overweight participants in a weight loss trial.

Despite considerable clinical interest, attempts to link perceived self-efficacy with successful weight control have had mixed success. Definitive data on prospective associations between self-efficacy and weight loss are particularly sparse. This study examined relationships between self-efficacy beliefs, weight control behaviors, and weight change among individuals participating in a weight loss trial (N = 349, 87% women). Cross-sectionally, eating and exercise self-efficacy beliefs were strongly associated with corresponding weight loss behaviors. Self-efficacy beliefs prospectively predicted weight control behavior and weight change during active treatment but not during follow-up. Mediational models indicate that people's weight control behaviors mediate the impact of self-efficacy on weight change.
