Judaism and Health: Reflections on an Emerging Scholarly Field

This paper surveys the field of Judaism and health. The authors trace the history of discourse on health and healing within Judaism, from the biblical and rabbinic eras to contemporary research and writing on Jewish bioethics, pastoral care, communal services, and aging, including congregational and community programming related to health and illness and the emergence of the Jewish healing movement. The work of the Kalsman Institute on Judaism and Health is described, focusing on efforts to unite these various threads into a scholarly field emphasizing basic and applied research on the instrumental functions of Jewish religious life for health and well-being.     

Experiences and perspectives of African American, Latina/o, Asian American, and European American psychology graduate students: A national study

A national, Web-based survey of 1,219 African American, Latina/o, Asian American, and European American psychology graduate students revealed both similarities and differences in experiences and perspectives. Mentoring was found to be the strongest predictor of satisfaction across groups. Academic supports and barriers, along with perceptions of diversity within the academic environment, were also important predictors of satisfaction. Students of color perceived less fairness of representation of their ethnic group within psychology than European American students, and a greater linkage between aspects of the graduate school experience and their ethnicity. Limitations of the study and implications for future research and action are discussed.     

The structure of vocational interests in Filipino adolescents

The structure of vocational interests was investigated in Filipino high school students (N = 503), who rated their interest in 303 culture-relevant occupational titles and 93 major fields of study. Item-level principal components analyses identified general interest, prestige, and sex-type dimensions, rather than Prediger's (1982) People/Things and Data/Ideas dimensions. Additional factor analyses were conducted to derive scales that measure more specific interests, including Unskilled/Semiskilled Labor, Male-dominated, Engineering/Technology, Science, Medical, Arts, Commerce, Government/Law, and Education. The interest scales showed some resemblance or overlap with Holland's types, and gender differences on the scales conformed to expectations. However, the relationships among the scales and occupations were better accounted for by prestige and sex-type than by People/Things and Data/Ideas dimensions or by Holland's circular model. Developmental, cultural, educational, and economic factors that might account for Filipino students' focus on prestige and sex-type were discussed.     

A mutual acculturation model of multicultural campus climate and acceptance of diversity

This study examines the relationship between college students' perceptions of their campus' multicultural climate and their acceptance of racial/ethnic diversity. A two-mediator model, based on acculturation principles, was successfully fit to survey data from 434 college students of diverse racial/ethnic heritage. Results showed that valuing positive interactions with members of ethnocultural groups other than one's own is a positive mediator and strength of ethnocultural identity is a (much less important) negative mediator of the relationship between student perceptions of multicultural campus programming and personal acceptance of diverse racial/ethnic groups. Furthermore, each mediator independently contributed to the prediction of such acceptance. Overall, the model accounts for about 25% of the variance in acceptance of diversity and was a better fit to the data than a reverse path model. Follow-up analyses, separately by ethnic group, showed that perceptions of campus programming predicted acceptance of diversity for the White subsample, but not for the Latino subsample. Nevertheless, the two acculturation-related constructs were important for both groups, with the model accounting for 28% and 24% of their respective variances in acceptance of diversity. Practical implications are drawn.     

Impact of predatory threat on fear extinction in Lewis rats

Humans with post-traumatic stress disorder (PTSD) are deficient at extinguishing conditioned fear responses. A study of identical twins concluded that this extinction deficit does not predate trauma but develops as a result of trauma. The present study tested whether the Lewis rat model of PTSD reproduces these features of the human syndrome. Lewis rats were subjected to classical auditory fear conditioning before or after exposure to a predatory threat that mimics a type of traumatic stress that leads to PTSD in humans. Exploratory behavior on the elevated plus maze 1 wk after predatory threat exposure was used to distinguish resilient vs. PTSD-like rats. Properties of extinction varied depending on whether fear conditioning and extinction occurred before or after predatory threat. When fear conditioning was carried out after predatory threat, PTSD-like rats showed a marked extinction deficit compared with resilient rats. In contrast, no differences were seen between resilient and PTSD-like rats when fear conditioning and extinction occurred prior to predatory threat. These findings in Lewis rats closely match the results seen in humans with PTSD, thereby suggesting that studies comparing neuronal interactions in resilient vs. at-risk Lewis rats might shed light on the causes and pathophysiology of human PTSD.Following a severe traumatic event, some individuals manifest a syndrome, known as post-traumatic stress disorder (PTSD), characterized by repeated painful recollection of the trauma, avoidance of trauma reminders, intrusive thoughts, startle, hyperarousal, and disturbed sleep. Lifetime prevalence of PTSD ranges from 1.4% to 11.2% in representative samples (Afifi et al. 2010). Review of heritability studies indicate that there is a significant genetic component to PTSD (Nugent et al. 2008) as shared genes explain approximately 25%–38% of variability in PTSD symptom clusters and total symptoms (Afifi et al. 2010). Moreover, PTSD heritability coincides with that of other psychiatric conditions such as generalized anxiety, panic disorder, and depression (Chantarujikapong et al. 2001; Fu et al. 2007), suggesting that these disorders gain expression through common biological pathways.Although our understanding of PTSD has improved recently, we still have a limited grasp of the factors that predispose some to be at risk for PTSD, as well as those contributing to PTSD expression following trauma. In part, this situation results from the ethical limitations associated with human studies. For example, humans cannot be randomly assigned to trauma, and, importantly, the invasive techniques required to study the pathophysiology of PTSD can be used only in animals. Thus, a promising approach toward understanding the underlying pathophysiology of PTSD would be to study the disease in a valid animal model of the human syndrome.Fortunately, much work has already been performed to define an animal model of PTSD that reproduces the salient features of the human syndrome (see Adamec et al. 2006; Cohen et al. 2006a; Siegmund and Wotjak 2006). The most promising research has focused on the impact of exposing rodents to species-relevant threatening stimuli that mimic the kind of life-and-death circumstances that precipitates PTSD in humans. Indeed, rodents exposed to predators or their odor develop long-lasting (3 wk or more) manifestations of anxiety as seen in a variety of behavioral assays including the elevated plus maze (EPM), social interaction test, and acoustic startle (Adamec and Shallow 1993; Blanchard et al. 2003; Adamec et al. 2006). The inherent strength of this species-relevant stimulus was demonstrated in studies where predator odor served as an unconditioned stimulus to support cued or contextual fear conditioning (Blanchard et al. 2001; McGregor et al. 2002). As is the case with human PTSD, differential vulnerability to predatory threat was also observed in rodents. In one study, for instance, the propensity of different strains of rats to develop extreme behavioral manifestations of anxiety (EBMAs) as a result of predatory threat has been characterized, revealing that a much higher proportion (50%) of Lewis rats (an inbred strain) develops EBMAs as a result of an intense predatory threat compared with 10% of Fisher rats and 20% of Sprague–Dawley rats (Cohen et al. 2006b).Although these results are promising, it remains unclear whether Lewis rats also exhibit traits that parallel the pathophysiology of human PTSD. One such factor, thought to play a particularly critical role in the persistence of PTSD, is a compromised ability to extinguish fear memories (for review, see Quirk and Mueller 2008). Two main lines of evidence support this notion. First, in functional imaging studies, the brain structures that normally support fear expression and extinction (for review, see Pape and Pare 2010) show abnormal activity patterns in PTSD (Rauch et al. 2006; Shin et al. 2006; Bremner et al. 2008; Milad et al. 2009). Second, several studies have reported that individuals with PTSD are deficient at extinguishing classically conditioned fear responses (Orr et al. 2000; Peri et al. 2000; Blechert et al. 2007; Milad et al. 2008, 2009). Of particular interest, a study of identical twins discordant for trauma exposure has revealed that this extinction deficit was not a pre-existing condition but developed as a result of trauma (Milad et al. 2008). Given the possibility that an inability to extinguish fear might contribute to the maintenance of PTSD, we therefore tested whether Lewis rats reproduced the properties of extinction seen in human PTSD.     

Ethnic Differences in Parents' Attitudes toward Girls' Use of Aggression

Few studies have attempted to explain ethnic differences in female aggression. The degree to which ethnic differences exist in the influence of parents' approval of aggression on their preadolescent daughters' use of physical, verbal, and relational aggression was explored in a sample of 97 parent-child dyads. Results indicate that European American parents were more disapproving of their daughters' aggressive behavior than were African American parents. Parents' attitude toward aggression was predictive of European American girls' use of physical and verbal aggression and African American girls' use of relational aggression. Implications for aggression prevention and intervention for girls are discussed.     

Effect of Short-Term Training on Reaching Behavior in Infants: A Randomized Controlled Clinical Trial

The purpose of this study was to test the effect of short-term training on reaching behavior in infants at the onset of reaching. The study was a single-blind, parallel group design, randomized controlled clinical trial. Thirty healthy infants were randomly assigned to a social control group (n = 15) or a reaching training group (n = 15). Infants began the study up to 3 days after the onset of reaching and were assessed three times across 2 days: pretraining (before training), posttraining 1 (after 1 session of training), and posttraining 2 (after 3 sessions of training). The reaching training group received 3 sessions of training by a physical therapist while the control group received a similar amount of time sitting in the therapist's lap. The data were analyzed using repeated-measures analyses of variance, and independent-samples tests with Bonferroni adjustments. Short-term training resulted in increased frequency of object contacts, shorter and smoother reaches, and improved hand positioning. The few short training sessions likely provided opportunities for infants to explore and learn to select movements from their existing movement repertoire. These results demonstrate that adaptive changes in infants' novel behaviors can emerge rapidly, and highlight the need for increased understanding of how to most effectively time early interventions.     

The Bulimia Workshop: A Unique Integration of Group Treatment Approaches

The time constraints of weekly group therapy and the slow evolution of group cohesion attenuate the direct confrontation that is essential with bulimic patients. Consequently, a three-phase, multidimensional group program was devised to accelerate the treatment process. Treatment begins with an intensive weekend workshop during which members formulate contracts for interrupting the binge–purge cycle and changing symptomatic behavior. During a follow-up session problems in fulfilling the contracts are dealt with and successes are reinforced, in the final phase, group members convene without their therapists to provide peer support, reevaluate contracts, and share feelings regarding treatment progress. The unique implications for treatment process and therapist interventions prompted by this new format are discussed, and preliminary research findings are highlighted.
