Development,Feasibility, and Refinement of a Toxic Stress Prevention Research Program

Innovative interventions accessible to at-risk populations to prevent the intergenerational cycle of toxic stress are needed. This paper describes the iterative development of a community-based intervention, 2Gen Thrive, which was designed to prevent toxic stress and promote resilience by improving caregiver capacity to respond to children’s emotional, behavioral, and developmental needs. 2Gen Thrive leverages the collaboration between a Children’s Hospital and an Early Head Start/Head Start education center to help low-income, minority families thrive in the context of risk factors for toxic stress. In this paper, we focus on the process of developing, piloting, and refining our 2Gen Thrive preventive intervention research program, which has been developed following a community-based participatory research (CBPR) approach. The primary objective was to pilot test two prevention interventions we adapted for use in this target population: Classroom Theraplay, a classroom-wide intervention designed to prevent toxic stress among children exposed to adversity by fostering nurturing relationships with their teachers; and Dialectical Behavior Therapy Skills Training for Parents (DBT4P), a group intervention developed to bolster parental responsiveness by teaching Dialectical Behavioral Therapy (DBT) mindfulness and emotion regulation skills. We evaluated qualitative and process data as well as quantitative data from standardized instruments, including The Classroom Assessment Scoring System (CLASS), Patient Health Questionnaire (PHQ-9), Difficulties in Emotion Regulation Scale (DERS), and Parenting Stress Index (PSI/SF). Results demonstrate the feasibility, acceptability, and appropriateness of these preventive interventions delivered in the early education setting, and of conducting intervention research using a CBPR approach.     

The Children's Social Vulnerability Questionnaire (CSVQ): Validation,relationship with psychosocial functioning,and age-related differences

Background/Objective: Social vulnerability refers to difficulties detecting potentially harmful interpersonal situations. Although it is an important predictor of psychosocial and interpersonal difficulties in clinical samples, research investigating this construct is scarce. We aimed to (a) develop a brief measure for assessing social vulnerability in typically developing children, the Children's Social Vulnerability Questionnaire (CSVQ) (b) examine the relationship between social vulnerability and psychosocial functioning, (c) explore age-related differences, and (d) explore levels of social vulnerability amongst children with clinical needs. Method: Data were gathered on two samples. Participants were parents (n = 790) of elementary school-aged children (3-12 years), and parents and teachers of a second sample (n = 96). Results: Results provide strong reliability and validity evidence. Social vulnerability showed moderate relationships with emotional and behavioural problems, and only a weak relationship with social skills. Parents perceived greater social vulnerability in younger than older children, and amongst children with clinical needs. Parents’ and teachers’ scores were correlated. Conclusions: Social vulnerability is not simply a lack of social skill; rather, it is a valuable construct for understanding psychosocial risk, especially for young and clinical samples of children.     

Grouping, chunking, memory, and learning

An example of grouping is dividing a long series of digits into two or more smaller units by, for example, pausing for a short time between items within groups but for a longer time between groups. Grouping, virtually neglected in animal learning, was examined in each of five rat investigations reported here in which a series of two or more runway trials was either grouped together with or apart from a terminal large reward trial. It was found that running speed on early small reward trials in the series was greater when prior trials were grouped together with rather than apart from the terminal large reward trial and this when the intertrial interval was short, 20 sec, or long, 20 to 40 min. Three possible explanations of the present findings were examined: a reward schedule view, a rule-learning view, and an anticipation view based on memory. The most feasible of these explanations, it was suggested, was the anticipation view. According to this view, when prior trials are grouped together with a terminal large reward, there is a tendency for the rat to anticipate the terminal large reward well before its scheduled occurrence, elevating running speed on earlier small reward trials. Such anticipation occurs, it was suggested, because when trials are grouped together the memory of each reward event in the series is retrieved on each subsequent trial, including the remote terminal large reward trial, where it becomes a signal for large reward. Thus the present results implicate not merely adjacent associations—associations between adjacent events—but also the highly controversial remote associations—associations between two events separated not only in time but by one or more intervening events as well.     

Cooking Living Beings:

Bodies play important and diverse roles in Buddhist ethics. Drawing upon an Indian Mahāyāna Buddhist compendium of bodhisattva practice, this paper explores the role bodhisattva bodies play in the ethical development of other living beings. Bodhisattvas adopt certain disciplinary practices in order to produce bodies whose very sight, sound, touch, and even taste transform living beings in physical and moral ways. The compendium uses a common South Asian and Buddhist metaphor to describe a bodhisattva's physical and moral impact on others. Bodhisattvas are said to “cook living beings.” The paper considers how this metaphor suggests ways of nuancing modern Western conceptions of ethical self‐cultivation, particularly as articulated by Michel Foucault in his studies of the technologies of the self.     

Effect of age on dual-task performance in children and adults

Age effects on dual-task costs were examined in healthy adults (Exp. 1) and in typically developing children (Exp. 2). In both experiments, individual differences in performance on the single-task components were titrated so that any age differences in dual-task costs could not be attributed to differences in single-task performance. Dual-task costs were found, but there were no age-related differences in these costs in older relative to younger adults, in 7-year-old relative to 9-year-old children, or across all four age groups. The results from these experiments suggest that previously reported age differences in dual-task costs, in both healthy ageing and child development, may be due to a failure to adequately equate single-task difficulty.     

Same-gender stalking in Sweden and Australia

This study examined the phenomenon of same-gender stalking and sought to identify differences between same- and opposite-gender stalking cases. Ninety-four same-gender and 160 opposite-gender stalking cases from Sweden and Australia were compared on demographic, offense, clinical, and behavioral characteristics. The groups were largely similar, differing mainly in the nature of the prior relationship between stalker and victim and the stalker's motivation. The most notable distinction was the significantly greater prevalence of ex-intimate partner stalkers in the opposite-gender group (65%) versus the same-gender group (32%), leading to the exclusion of ex-intimates from the subsequent analysis to remove this potentially confounding variable. Amongst non-ex-intimates, same-gender stalkers were significantly more likely to be female and to stalk out of a sense of resentment and grievance. The results showed that the gender of the victim and perpetrator was less important to the course and conduct of a stalking episode than were the stalker's motivation and the nature of the prior relationship to the victim.     

Is longing only for Germans? A cross-cultural comparison of Sehnsucht in Germany and the United States

Sehnsucht, the longing or yearning for ideal yet seemingly unreachable states of life, is a salient topic in German culture and has proven useful for understanding self-regulation across adulthood in a German sample (e.g., Scheibe, Freund, & Baltes, 2007). The current study tested whether findings for German samples could be generalized to the more individualistic and agentic U.S. American culture. Four samples of U.S. American and German participants (total N = 1,276) age 18 to 81 years reported and rated their 2 most important life longings and completed measures of subjective well-being and health. Measurement equivalence was established at the level of factor loadings for central life longing characteristics. German and U.S. American participants did not differ in self-reported ease of identifying personal life longings or their intensity. In comparison to Germans, however, U.S. Americans associated life longings less with utopian, unattainable states and reported less salience of the concept in everyday life. Associations with measures of adaptation suggest that life longings can be both functional and dysfunctional for development in both cultures.
