Accommodating Small Sample Sizes in Three-Level Models When the Third Level is Incidental

Small samples sizes are a pervasive problem when modeling clustered data. In two-level models, this problem has been well studied, and several resources provide guidance for modeling such data. However, a recent review of small-sample clustered data methods has noted that no studies have investigated methods for modeling three-level data with small sample sizes. Furthermore, strategies for two-level models do not necessarily translate to the three-level context. Moreover, three-level models are prone to small samples because the “small sample” designation is primarily based on the sample size of the highest level, and large samples are increasingly difficult to amass as one progresses up a hierarchy. In this study, we focus on the case when the third level is incidental, meaning that the third level is important to consider but there are no explicit research questions at the third level. This study performs a simulation study to examine the performance of seven methods for modeling three-level data with a small sample at the third level. A motivating educational psychology example is also provided to demonstrate how the choice of method can greatly affect results.     

The Interplay Between Housing Stability and Child Separation: Implications for Practice and Policy

Greater understanding of how residential stability affects child separation and reunification among homeless families can guide both child welfare and homeless policy and practice. This article draws upon two longitudinal studies examining services and housing for homeless families and their relationship to family and housing stability. Both studies were conducted in the same state at roughly the same time with similar instruments. The first study, examining families’ experiences and outcomes following entry into the homeless service system in three counties in Washington State, found that at 18 months following shelter entry, families that are intact with their children were significantly more likely to be housed in their own housing (46%) than families that were separated from one or more of their children (31%). The second study, a quasiexperimental evaluation of a supportive housing program for homeless families with multiple housing barriers, found that the rates of reunification for Child Protective Services (CPS)‐involved families receiving supportive housing was comparable to that for families entering public housing without services, but significantly higher than the rate of reunification for families entering shelter. Taken together, the findings from both studies contribute to the evidence underscoring the importance of housing assistance to homeless families involved in the child welfare system.     

Selling Innovations Like Soap: The Interactive Systems Framework and Social Marketing

Despite the popularity and noted utility of Wandersman and colleagues' (2008) Interactive Systems Framework, the literature currently provides a primary focus on delivery organizations’ and supportive stakeholders’ capacities and strategies to implement innovations, presenting a critical gap in understanding. Unfortunately, reflective of a larger void in community dissemination and implementation efforts, there is a more limited focus on the dissemination of innovations. This paper presents the social marketing literature as a supplement to the Prevention Synthesis and Translation System (PSTS), the system responsible for dissemination. The study and practice of innovation synthesis and translation is examined in the literature; and based on the conclusions drawn, social marketing theory is used to provide a systematic approach to improving dissemination within the Interactive Systems Framework. Specifically, three gaps related to the PSTS are identified in the literature that align with and can be filled using social marketing. Social marketing is defined and presented as a supplement by providing theory and practices, within a systems context, for effectively communicating and influencing change. By blending social marketing with the Interactive Systems Framework, the aim is to improve the understanding of strategic communication and its role in the effective dissemination, and subsequent implementation, of innovations.     

Partial replication of two rumination-related candidate gene studies

Two recent papers associated candidate genes with brooding rumination, a possible cognitive endophenotype for depression, in children ages 8–14 years. Stone et al. reported that BDNF val66met polymorphism predicted brooding in adolescence. Woody et al. reported that children carrying at least one copy of a CRHR1 TAT haplotype reported less brooding than their peers in the presence of maternal depression. We attempted to replicate and extend these findings in a sample of twins aged 12–16 years. We analyzed the BDNF val66met (rs6265) polymorphism and two (rs242924 and rs7209436) out of three single nucleotide polymorphisms (SNPs) that Woody et al. used to create a CRHR1 haplotype. We controlled for maternal history of depression and clustering within families. Unlike Stone et al., we found higher brooding among BDNF Met carriers. This main effect was qualified by an interaction with pubertal status, with the effect driven by more physically mature participants. Similar to Woody et al., we found an interaction between CRHR1 SNPs and maternal depression, with the homozygous minor genotype acting as a protective factor against brooding in the presence of maternal depression. Findings provide partial support for the influence of candidate genes in two environmentally sensitive systems on brooding.     

Open-Trial Pilot of Parent-Child Interaction Therapy for Children With Autism Spectrum Disorder

In this pilot study, the effectiveness and feasibility of Parent-Child Interaction Therapy (PCIT) for decreasing disruptive behavior was evaluated in 17 young children with Autism Spectrum Disorder (ASD). PCIT is a behaviorally based play therapy which targets the parent-child relationship through live coaching of play interactions and the implementation of consistent discipline techniques. Following an average of 19 sessions, disruptive behavior as measured by multiple indices significantly decreased. Congruently, parents increased positive parental following skills and decreased negative parental leading skills across the course of treatment. In addition, parents reported increased levels of child functional communication and prosocial behavior. High levels of parent acceptability of the intervention were also noted. Effect sizes were medium to large across measured dependent variables, including parent report and behavioral observations. Implications for the clinical use of PCIT within an ASD population and future research with controlled outcome studies are discussed.     

‘I think a little bit of a kick is sometimes what you need’: Women’s accounts of whole-body scanning and likely impact on health-related behaviours

Objective: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image.

Design: Fourteen women aged 22–45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis.

Results: Scans did not look as expected, and participants expressed ‘surprise’ and ‘shock’. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too ‘real’ and ‘raw’. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning.

Conclusion: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.     

Examining the Merit of Grit in Women's Soccer: Questions of Theory,Measurement, and Application

The purpose of the current study was to examine the factorial validity of existing grit measures and to examine differences in the grit level of athletes across performance tiers (i.e., collegiate, professional, Olympic). Female soccer players (N = 305) of varying competitive levels completed measures of grit. Results revealed preliminary support for the 8-item Grit Scale factorial validity, as well as a significant age-adjusted difference in grit level between Division I and Division II collegiate athletes. Taken together, study results prompt questions regarding the theoretical underpinnings, and consequent measurement, of the grit construct in sport psychology practice.     

A Qualitative Study of Factors Influencing Decision-Making after Prenatal Diagnosis of down Syndrome

Previous research has identified twenty-six factors that may affect pregnancy management decisions following prenatal diagnosis of DS; however, there is no consensus about the relative importance or effects of these factors. In order to better understand patient decision-making, we conducted expansive cognitive interviews with nine former patients who received a prenatal diagnosis of DS. Our results suggest that patients attached unique meanings to factors influencing decision-making regardless of the pregnancy outcome. Nineteen of the twenty-six factors previously studied and four novel factors (rationale for testing, information quality, pregnancy experience, and perception of parenting abilities and goals) were found to be important to decision-making. We argue that qualitative studies can help characterize the complexity of decision-making following prenatal diagnosis of DS.     

Children’s Attitudes toward Aggression: Associations with Depression,Aggression, and Perceived Maternal/Peer Responses to Anger

Little is known about factors that influence children’s attitudes toward aggression, despite evidence that these attitudes are influential in promoting violent behaviors. The purpose of the present research was to examine the relation of self, peer, and parent social factors to school-age children’s maladaptive attitudes toward aggression. Specifically, symptoms of depression, peer overt aggression behaviors, and perceptions of maternal and peer responses to anger were evaluated as important factors associated with the use of aggression. These factors were examined separately for boys and girls, as research has consistently documented gender differences in the form and use of aggression. Hierarchical regression models were computed separately for boys and girls in grades three through five (N?=?167), with child-reported depression, peer-nominated overt aggression, and child-reported maternal and best friend responses to anger examined as predictors of maladaptive attitudes toward aggression. For girls, depressive symptoms positively predicted maladaptive attitudes toward aggression. For boys, the extent of peer-reported overt aggression (positively) and child-reported supportive maternal responses to the child’s anger (negatively) predicted maladaptive attitudes toward aggression. The value of examining social factors that relate to attitudes toward aggression is discussed as well as consideration of gender differences in these relations. In addition, discussion includes how these results highlight important targets for interventions that may be especially relevant for school-age girls and boys.
