Model-based recursive partitioning of extended redundancy analysis with an application to nicotine dependence among US adults

Extended redundancy analysis (ERA) is used to reduce multiple sets of predictors to a smaller number of components and examine the effects of these components on a response variable. In various social and behavioural studies, auxiliary covariates (e.g., gender, ethnicity) can often lead to heterogeneous subgroups of observations, each of which involves distinctive relationships between predictor and response variables. ERA is currently unable to consider such covariate-dependent heterogeneity to examine whether the model parameters vary across subgroups differentiated by covariates. To address this issue, we combine ERA with model-based recursive partitioning in a single framework. This combined method, MOB-ERA, aims to partition observations into heterogeneous subgroups recursively based on a set of covariates while fitting a specified ERA model to data. Upon the completion of the partitioning procedure, one can easily examine the difference in the estimated ERA parameters across covariate-dependent subgroups. Moreover, it produces a tree diagram that aids in visualizing a hierarchy of partitioning covariates, as well as interpreting their interactions. In the analysis of public data concerning nicotine dependence among US adults, the method uncovered heterogeneous subgroups characterized by several sociodemographic covariates, each of which yielded different directional relationships between three predictor sets and nicotine dependence.     

Adolescents’ Civic Commitments in Stable and Fledgling Democracies: The Role of Family,School, and Community

The authors examined the associations between adolescents’ perceptions of proximal processes in families, schools, and communities and their civic commitments (to the local community, nation, and conventional politics) in stable (Australia, United States) and fledgling (Bulgaria, Hungary) democracies in the mid-1990s. Results of multivariate analysis of covariance (MANCOVA) revealed that adolescents in the stable democracies reported higher levels of extracurricular participation, family emphasis on social responsibility, and community social capital compared to peers in the fledgling democracies. Using a multiple group regression approach, the authors found that in both types of polities, community social capital was positively associated with all three civic outcomes and a family ethic of social responsibility was positively associated with commitments to the local community and nation. However, whereas in the stable democracies, a democratic school climate was positively associated with commitments to the community and nation, in the fledgling democracies such school climates were positively associated with commitments to conventional politics.     

Caregiving for children through conflict and displacement: a pilot study testing the feasibility of delivering and evaluating a light touch parenting intervention for caregivers in the West Bank

A child's adjustment to wartime stress is reliant not only on individual responses and qualities, but very significantly on the availability of support that they may receive from their parent or caregivers and quality of relationships. Strengthening parental support has the potential to be valuable. A pilot two-arm randomised controlled trial investigated the feasibility of delivering and evaluating the “Caring for Children Through Conflict and Displacement” intervention with caregivers in the West Bank. Feasibility to recruit and train non-specialist staff on-the-ground to screen families for eligibility, collect outcome data, deliver the intervention and to recruit and retain families in the study were examined. Research staff and intervention facilitators were successfully appointed in the field, screened participants and delivered the intervention to 120 caregivers, collecting outcome measures pre-and post-delivery. All families completed the outcome measures, with very little missing data. This indicated that the intervention can be delivered feasibly and evaluated with families in this humanitarian context. Preliminary outcome data showed promise that the intervention may have the potential to both improve family functioning and reduce children's problem behaviour. Implications of family-focused initiatives, particularly within a conflict/post-conflict context for the prevention of several negative health and social outcomes directions, are discussed.     

Dimensions of Religion and Spirituality: A Longitudinal Topic Modeling Approach

In lieu of the traditional text data analysis methods, structural topic modeling was utilized to analyze the text contents of 255 self-report inventories of religion and spirituality (R/S) published from 1929 to 2017. The study had two objectives: (a) to clarify and identify the latent dimensions of R/S inherent in the items of the measures; and (b) to examine and demonstrate the usefulness of a longitudinal topic modeling in the study of R/S. We identified 5,617 unique text terms from the measures and fitted topic models on those terms to extract latent dimensions called topics. We also simultaneously analyzed the longitudinal effect of publication decade (i.e., 1950s–2010s) on the topics. A topic model with three topics was chosen to best support the data: Experience of Transcendence (Topic 1), Engagement in Transcendence (Topic 2), and Essence of Transcendence (Topic 3). In addition, the longitudinal analysis revealed that Topic 1 showed a continual increase over the decades, while Topics 2 and 3 both demonstrated a gradual decrease, in effect matching the general trend of Topic 1's increasing popularity in society and the academia.     

A novel in vivo measure of cyberaggression

Cyberaggression (CA), or the use of information communication technologies to inflict harm on others, is an emerging public health crisis. Unfortunately, our current ability to assess CA in a research context remains limited, curtailing efforts to address this important issue. We sought to fill this gap in the literature by developing an adapted “chat” version of the Taylor aggression paradigm (TAP) that would more closely resemble a social gaming format (hereafter referred to as the TAP-Chat). In the TAP-Chat, participants have a chat function available to communicate with their (fictitious) co-player. Following loss trials in a competitive reaction time task, they receive a “mean chat” from their co-player. Participant messages to their (fictitious) co-player are then coded for aggressive content by a team of trained research assistants, and via automated linguistic analysis software (Linguistic Inquiry and Word Count). The current study evaluated the predictive utility of the TAP-Chat task in independent discovery and replication samples (N = 843 and N = 350, respectively). Participants’ publicly available tweets served as an important external criterion variable, along with a handful of self-report questionnaires assessing CA and related constructs. Analyses suggest that, although it can be completed in ∼13 min, the TAP-Chat predicts CA on Twitter and, to a lesser extent, as reported on questionnaires. Although there are still several issues to address, it is our hope that the research community will benefit from this straightforward behavioral assessment of CA.     

Self-Acceptance Group Therapy: A Transdiagnostic,Cognitive-Behavioral Treatment for Shame

Shame has broad importance to psychological problems. However, few interventions specifically address shame, and most of these have been designed to target shame in the context of particular disorders. Self-Acceptance Group Therapy (SAGT) was developed as a transdiagnostic shame-focused treatment, based on a cognitive-behavioral framework. SAGT is an 8-week treatment that involves psychoeducation and training in the use of cognitive and behavioral shame regulation and support-building skills in order to promote self-acceptance. After describing SAGT, the study presented used an open trial design to examine the utility of SAGT for addressing shame, self-acceptance, quality of life, and relevant psychological problems (e.g., depression, social anxiety). Twenty-four outpatients with elevated shame were assessed at pretreatment, posttreatment, and 1-month follow-up. By post-treatment, results revealed significant improvements in self-acceptance, shame, and borderline personality disorder (BPD) symptoms among treatment completers (n = 18), with all of these improvements maintained at follow-up. Additionally, significant improvements in quality of life, emotion dysregulation, depression, loneliness, and stress were observed at follow-up. Results provide preliminary support for SAGT’s utility in the treatment of shame and related pathology among diverse outpatients.     

Relationships Between Social Support,Internal Assets,and Life Satisfaction in Korean Adolescents

In previous literature, social support has been reported to have a significant, positive relationship with life satisfaction. However, few studies have examined this relationship among Korean youths and how their psychological functioning is associated with both social support and life satisfaction. This study investigated the associations between different sources of social support (i.e., family, peer, and teacher), psychological factors (i.e., self-efficacy and emotional regulation), and life satisfaction, in a sample of 1133 Korean adolescents. The possibility of sex differences in these relationships was also investigated. Results indicated that only family support had a direct relationship with life satisfaction for male adolescents; however, all three types of social support were found to have a significant, indirect relationship with life satisfaction for male adolescents through both psychological factors. In contrast, all three types of social support had a direct relationship with life satisfaction of female adolescents. Additionally, self-efficacy had a mediating effect on the relationship between the social support from family and teachers and life satisfaction of female adolescents. The results and implications of the study are discussed.     

What Does “Happiness” Prompt in Your Mind? Culture,Word Choice,and Experienced Happiness

What three words come to your mind in association with “happiness”? We analyzed the 1563 words reported by 521 Korean and American participants in this free association task. The most frequently endorsed word was “family” in Korea, whereas the most popular word among Americans was “smile.” The overall frequency of social words (e.g., relationships, social emotions) reported by Koreans was higher, and the most often mentioned relationship type differed between the two groups (family in Korea; friend in the US). Nonetheless, both in Korea and the US, individuals who mentioned more social words were significantly more satisfied with their lives. The amount of social support provision mediated the link between the number of reported social words and experienced happiness. Regardless of culture, a simple count of social words associated with happiness appears to offer a reasonably good clue for how happy the person actually is.     

A Narrative Analysis of Sibling Grief

Sibling grief is linked to serious physical and mental health outcomes, yet remains the least researched of all family bereavement. This exploratory study created a shared sibling grief narrative. Open-ended interviews were conducted with 27 participants who lost a sibling. Primary themes included Shared Life: Identity Within the Sibling Arrangement; Sibling Death: Pivotal Moments in Time; Life After Sibling Loss: Emotional Suffering, Life After Sibling Loss: Missing Roles & Changing Relationships; and The Sibling Lives On. The following study findings clarify the overlooked impact that sibling death has on the surviving sibling and demonstrate the crucial need for more sibling loss research.
