Program evaluation of trauma-informed yoga for vulnerable populations

BackgroundTrauma is highly prevalent among vulnerable populations, including those who are incarcerated, in treatment for substance use, or seeking mental health services. Trauma-informed yoga seeks to create a safer yoga practice for individuals with a trauma history and may improve emotional and physical wellbeing. Thus, we conducted an evaluation of a trauma-informed yoga program to gain insight into participant experiences.MethodsTrauma-informed yoga classes were led by trained volunteers and held in three sectors that work with vulnerable populations: corrections and reentry, substance use treatment and recovery, and community and mental health. Data were collected via anonymous survey using a retrospective pre-post design. The survey instrument captured reasons for student participation and perceived effects of yoga on emotional and physical wellbeing.ResultsStudents were motivated to participate in yoga classes by expectations of physical, mental, and spiritual benefit. Students reported perceived improvements in emotional and physical wellbeing and greater use of self-regulation skills after starting yoga.ConclusionOur findings suggest trauma-informed yoga is perceived as beneficial by vulnerable individuals, especially those in the correctional system or recovering from substance use. Our results support the value of offering trauma-informed yoga in institutionalized and community settings. Improvements in emotional and physical wellbeing warrant formal study.     

Enhancing Recovery from Trauma: Facilitating a Mindfulness Skills Group on a Department of Veterans Affairs Inpatient PTSD Unit

Mindfulness and acceptance based treatments are being increasingly implemented for a variety of emotional and psychological related problems, including the impact of military and combat related trauma exposure. This article describes a mindfulness skills group as it was implemented on a sub-acute inpatient PTSD Unit at a Department of Veterans Affairs medical center, to demonstrate and explore the role of the mindfulness skills development in a group setting, for Post-Traumatic Stress Disorder and other trauma related problems.     

Bayesian Accelerated Life Testing under Competing Weibull Causes of Failure

Consider a J-component series system which is put on Accelerated Life Test (ALT) involving K stress variables. First, a general formulation of ALT is provided for log-location-scale family of distributions. A general stress translation function of location parameter of the component log-lifetime distribution is proposed which can accommodate standard ones like Arrhenius, power-rule, log-linear model, etc., as special cases. Later, the component lives are assumed to be independent Weibull random variables with a common shape parameter. A full Bayesian methodology is then developed by letting only the scale parameters of the Weibull component lives depend on the stress variables through the general stress translation function. Priors on all the parameters, namely the stress coefficients and the Weibull shape parameter, are assumed to be log-concave and independent of each other. This assumption is to facilitate Gibbs sampling from the joint posterior. The samples thus generated from the joint posterior is then used to obtain the Bayesian point and interval estimates of the system reliability at usage condition.     

Point estimation of the stress–strength reliability parameter for parallel system with independent and non-identical components

In this article, the estimation problem of the multicomponent stress–strength reliability parameter is considered where the stress and the strength systems have arbitrary fixed numbers of independent and non-identical parallel components. It is assumed that the distribution functions of the stress and the strength components satisfy the proportional reversed hazard rate model. The study is done in more details when the baseline distributions are exponential. Maximum likelihood and uniformly minimum variance unbiased estimators are obtained and compared. Also, Bayes and empirical Bayes estimators are discussed and Monte Carlo simulations are carried out to compare their performances.     

Inferences on stress–strength parameter based on GLD5 distribution

Let X and Y be independent random variables distributed as generalized Lindley distribution type 5 (GLD5). This article deals with the estimation of the stress–strength parameter R = P(Y < X), which plays an important role in reliability analysis. For this purpose, the maximum likelihood and the uniformly minimum variance unbiased estimators are presented in the explicit form. Moreover, considering Arnold and Strauss’ bivariate Gamma distribution as an informative prior and Jeffreys’ as noninformative prior, the Bayes estimators are derived. Various bootstrap confidence intervals are also proposed and, finally, the presented methods are compared using a simulation study.

Home sweet home? Home physical environment and inflammation in children

The home environment includes important social and physical contexts within which children develop. Poor physical home environments may be a potential source of stress for children through difficult daily experiences. Using a sub-sample from the Los Angeles Family and Neighborhood Survey (N = 425), we consider how the home physical environment affects stress-related immune system dysregulation in children ages 3–18 years. Results indicated that children in poorer quality homes had higher inflammation (measured by C-reactive protein). The associations were particularly strong for younger children. We also found that part of the home physical environment association with CRP worked through increased risk of obesity for children living in low-quality homes. Future research should assess how home physical environments could be improved to reduce stress and improve health outcomes in children.     

服务氛围与一线员工服务绩效:工作压力和组织认同的调节效应研究

在以往服务管理研究领域中,服务氛围在多个层面上对服务产出的促进作用得到了广泛认可.然而,当前较少有文献对这种积极作用发生的权变性予以关注.基于社会交换理论,本文从个体层面上研究了一线员工感知的服务氛围影响服务绩效的作用机制,旨在探讨员工在工作环境中的情感体验(工作压力感和组织认同感)对服务氛围与服务绩效之间关系的调节作用.研究利用我国银行业368名一线服务员工的问卷调查数据验证了所提出的假设,实证结果发现:(1)工作压力感负向调节服务氛围与角色外服务绩效之间的关系;(2)组织认同感对服务氛围与角色内/外绩效的关系均产生正向调节作用;(3)进一步的三项交互(Three-way Intenction)分析还发现:当组织认同感较高时,工作压力对服务氛围与角色外服务绩效之间关系的负向调节作用变弱.     

Social support,self-efficacy and gender as predictors of reported stress among inpatient caregivers

The study examined the predictive role of social support, self-efficacy and gender on self-reported stress among inpatients’ caregivers. One hundred and sixty eight (36 males and 132 females) inpatients’ caregivers were sampled from University of Nigeria Teaching Hospital (97) and Niger Foundation Hospital (71) all in Enugu, Nigeria. Three instruments were used for the data collection, namely, Multidimensional Scale of Perceived Social Support (MSPSS), New General Self Efficacy Scale (NGSES), and the Perceived Stress Scale (PSS). The study adopted a cross sectional design and Multiple Regression was used for data analysis. Results showed that social support negatively predicted inpatient caregivers’ reported stress (β = ?.28, p < .001). Gender significantly predicted stress among the inpatients’ caregivers (β = .35, p < .001). Findings were discussed and implications of the study highlighted.     

Moderators of the relationship between daily work stressors and mood

Consistent with recent data showing a relationship between daily stress and mood, the authors investigated whether job specific factors would moderate the relationship between daily work stress and daily mood. Forty-three subjects from one teaching hospital initially completed questionnaires assessing the hypothesized moderator variables (emotional and informational support from the supervisor, job involvement, co-worker satisfaction, supervision satisfaction, and satisfaction with the meaningfulness of work). Thereafter, they completed questionnaires at the end of each workday assessing the number and negative perception of daily work stress and daily mood. After controlling for the effects of the different number of days for which data were available for each subject, the results showed that job involvement and all three facets of job satisfaction (supervision, co-worker, and work itself) moderated the relationship between the negative perception of daily work stress and mood. Neither emotional nor informational support from the supervisor moderated this relationship. Likewise, none of these variables moderated the relationship between the number of daily work events and mood. The results are discussed in terms of further research on daily work stress, and expanding and refining the focus on moderator variables.
