Youth with Chronic Pain and Postural Orthostatic Tachycardia Syndrome (POTS): Treatment Mediators of Improvement in Functional Disability

Intensive pain rehabilitation programs are effective in increasing functioning for youth with chronic pain (CP). However, the utility of such programs for youth with CP and co-morbid postural orthostatic tachycardia syndrome (POTS) is rarely examined. In addition, studies examining mediators of treatment for CP are sparse. This paper compares treatment outcomes for youth with CP (n?=?117) and youth with CP?+?POTS (n?=?118). Additionally, depression and pain catastrophizing were tested as potential mediators of treatment effects. Significant treatment improvements were found for functional disability, depression, pain catastrophizing, and perceived pain intensity but with no differences between groups. Improvements in depressed mood, pain catastrophizing (helplessness subscale), and pain severity partially mediated functioning improvement. Pain severity was not a significant mediator in the CP?+?POTS group. We concluded that depression and pain catastrophizing, especially the helplessness domain, can impact functioning improvement in adolescents with CP and POTS and are particularly important to target in treatment.     

Gay Identity and HIV Risk for Black and Latino Men Who Have Sex with Men

Strong gay identity among white men who have sex with men (MSM) has been associated with decreased HIV risk, but data for black and Latino MSM (BLMSM) are inconclusive. We examined gay identity and HIV risk among BLMSM to inform social and structural HIV intervention strategies. BLMSM were administered a computerized survey as part of an HIV research study during 2011–2012 conducted in New York City. We used a brief scale of Gay Identity Questionnaire. After data analysis, Stage I (not fully accepting) and Stage II (fully accepting) gay identity were determined based on participant responses. We used logistic regression to calculate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the association between gay identity with HIV risk and social determinant factors. Among 111 self-identified BLMSM (median age = 32 years, 68.4% with some college or higher education), 34.2% reported receptive anal sex without condoms in the previous three months. Gay Identity Questionnaire Scale assessment indicated that 22 (19.8%) were Stage I, and 85 (76.6%) were Stage II in this BLMSM sample. Stage II gay identity was more likely seen among BLMSM with high involvement in the gay community (aOR 3.2; CI 1.00, 10.26) and less likely among BLMSM who exchanged sex for food or shelter (aOR 0.15; CI 0.02, 0.98). Fully accepting gay identity may be protective for BLMSM as it relates to transactional sex; these factors warrant further research and consideration as part of HIV prevention strategies.     

Asthma-specific cognitions,self-focused attention,and fear of negative evaluation in adolescents and young adults diagnosed with childhood-onset asthma

The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning.     

A longitudinal analysis of the relationship between self-compassion and the psychological effects of perceived stress

ABSTRACT

Self-compassion is consistently associated with psychological well-being, but most research has examined their relationship at only a single point in time. This study employed a longitudinal design to investigate the relationship between baseline self-compassion, perceived stress, and psychological outcomes in college students (n = 462) when the outcomes were measured both concurrently with perceived stress and after a lag of six months. Self-compassion moderated the effects of perceived stress such that stress was less strongly related to depression, anxiety, and negative affect among participants who scored high rather than low in self-compassion. Self-compassion also moderated the effects of perceived stress on depression and anxiety prospectively after six months. Self-compassion predicted positive affect but moderated the effects of perceived stress on positive affect in only one analysis. This study suggests that high self-compassion provides emotional benefits over time, partly by weakening the link between stress and negative outcomes.     

The City Infant Faces Database: A validated set of infant facial expressions

Adults need to be able to process infants’ emotional expressions accurately to respond appropriately and care for infants. However, research on processing of the emotional expressions of infant faces is hampered by the lack of validated stimuli. Although many sets of photographs of adult faces are available to researchers, there are no corresponding sets of photographs of infant faces. We therefore developed and validated a database of infant faces, which is available via e-mail request. Parents were recruited via social media and asked to send photographs of their infant (0–12 months of age) showing positive, negative, and neutral facial expressions. A total of 195 infant faces were obtained and validated. To validate the images, student midwives and nurses (n = 53) and members of the general public (n = 18) rated each image with respect to its facial expression, intensity of expression, clarity of expression, genuineness of expression, and valence. On the basis of these ratings, a total of 154 images with rating agreements of at least 75% were included in the final database. These comprise 60 photographs of positive infant faces, 54 photographs of negative infant faces, and 40 photographs of neutral infant faces. The images have high criterion validity and good test–retest reliability. This database is therefore a useful and valid tool for researchers.     

Viral videos and virtue: Moral elevation inductions shift affect and interpersonal goals in daily life

Laboratory studies suggest that witnessing virtuous acts triggers moral elevation, an emotion characterized by feeling uplifted and increased prosocial motives. However, it remains unknown whether regular inductions can increase elevation and prosocial motives in daily life without being vulnerable to habituation or adaptation effects. Participants (total N = 181) were randomly assigned to elevating vs. neutral or amusing inductions (video or recall tasks) for seven days (Study 1), ten days (Study 2), or 12 days over one month (Study 3). Multilevel growth models showed that relative to comparison conditions, elevation inductions increased daily elevation, positive affect, and prosocial outcomes (compassionate goals and affiliation), and decreased self-protective motives (self-image goals). Adaptation effects occurred for immediate responses when exercises occurred daily, but not when spaced out over time, and not for outcomes measured later each day. Results suggest benefits of brief, regular elevation experiences and have implications for interventions targeting specific emotions.

Regulation of low-threshold afferent activity may contribute to short-term habituation in Aplysia californica

The goal of this study was to characterize the contribution of a population of low-threshold mechanoreceptors to short-term habituation of siphon-elicited reflex responses in Aplysia californica. Since the location of their somata is unknown, we refer to them as the Unidentified Low-Threshold mechanoreceptors (ULTs). The ULTs operate in parallel to the higher-threshold and well-characterized LE sensory neurons, yet little is known regarding their contribution to behavioral plasticity. Using extracellular recordings from the siphon nerve, we found that habituation training that favors ULT activation resulted in a significant decrease in afferent activity at training intervals up to 1 min per stimulus (1 min ISI). To determine how this reduction impacts responses at other sites of the reflex network, we used intracellular recordings to measure training-induced changes in either L29 excitatory interneurons or LFS siphon motor neurons. With a 30s ISI, changes at both locations were training site-specific and matched the rate of change of afferent activity, implicating regulated sensory activity as a primary mechanism. With a shorter training interval (1s ISI), site-specificity of training was not observed in the L29s, but was still preserved in the motor neurons. For both, the rate of change during training was faster than the rate of change of afferent activity. Taken together, we conclude that regulation of low-threshold sensory neuron activity can play a significant role in short-term habituation, but other network processes may be recruited at more rapid training intervals.
