Belowground insect herbivory induces systemic volatile emissions that strengthen neighbouring plant resistance aboveground.

Plants transmit ecologically relevant messages to neighbouring plants through chemical cues. For instance, insect herbivory triggers the production of herbivore-induced plant volatiles (HIPVs), which can enhance neighbouring plant defences. HIPVs are emitted from directly damaged plant tissues and from systemic, nondamaged tissues. Although volatile-mediated interplant interactions have been observed both above- and belowground, it remains unknown whether belowground herbivory induces systemic HIPVs aboveground that influence neighbouring plants. To explore how belowground herbivory affects interplant interactions aboveground, we characterised systemic HIPVs from squash induced by belowground striped cucumber beetle (Acalymma vittatum) larval herbivory. We exposed squash 'receiver plants' to systemic HIPVs or volatiles from nondamaged plants. We then measured herbivore resistance by challenging 'receiver plants' with aboveground-feeding herbivores: adult beetles (A. vittatum) or squash bugs (Anasa tristis). We discovered belowground-damaged plants emitted more (E)-ß-ocimene, a key volatile from the systemic HIPV blend, than nondamaged controls, and that exposure to systemic HIPVs enhanced neighbouring plant resistance to aboveground squash bugs, but not adult beetles. Further investigations into the mechanism of interplant interaction revealed ß-ocimene alone can elicit plant resistance against squash bugs. Overall, our findings reveal a novel form of volatile-mediated interactions between plants spanning across aboveground-belowground plant systems.

Developmental stasis, sensitivity, and disturbance: Linking concepts to analytic methods using impulsivity and alcohol use.

The goals of this article are to (a) describe and contrast conceptual characteristics of periods of developmental sensitivity, disturbance, and stasis, and (b) translate these concepts to testable analytic models with an example dataset. Although the concept of developmental sensitivity is widely known, the concepts of developmental stasis and disturbance have received less attention. We first define the concepts and their principles and then, using repeated measures data on impulsivity and alcohol use from adolescence to young adulthood, propose the dual latent change score (LCS) growth model as one analytic approach for evaluating evidence for key characteristics of these developmental concepts via examination of intraindividual time-varying associations.

Understanding heterogeneity in pathways between interparental conflict and children's involvement: The moderating role of affect-biased attention.

The study examined the moderating role of children's affect-biased attention to angry, fearful, and sad adult faces in the link between interparental conflict and children's distinct forms of involvement. Participants included 243 preschool children (Mage  = 4.60 years, 56% female) and their parents from racially (48% African American, 43% White) and socioeconomically (median annual household income = $36,000) diverse backgrounds. Data collection took place in the Northeastern United States (2010-2014). Utilizing a multi-method, multi-informant, longitudinal design, attention away from anger selectively amplified the link between interparental conflict and children's subsequent coercive involvement (ß = -.15). Greater attention to fear potentiated the pathway between interparental conflict and children's later cautious (ß = .14) and caregiving involvement (ß = .15). Findings are interpreted in the context of environmental sensitivity models.

Interparental conflict as a quadratic predictor of children's reactivity to interparental conflict and school adjustment: Steeling effects or risk saturation?

This study examined interparental conflict as a curvilinear predictor of children's reactivity to interparental conflict and, in turn, their school problems across three annual measurements. Participants included 243 preschool children (Mage  = 4.60 years; 56% girls) and their parents from racially (e.g., 48% Black; 16% Latinx) diverse backgrounds. Interparental conflict was a significant quadratic predictor of children's emotional reactivity (ß = .23) and behavioral dysregulation (ß = .27) to conflict over a 1-year period. The robust association between interparental conflict and behavioral dysregulation weakened at high levels of interparental conflict. In contrast, interparental conflict more strongly predicted children's emotional reactivity as conflict exposure increased. Children's emotional reactivity, in turn, predicted their greater school problems 1 year later (ß = .25).

Delineating the developmental sequelae of children's risky involvement in interparental conflict.

The present study examined the developmental value of parsing different forms of children's risky involvement in interparental conflict as predictors of children's subsequent psychological adjustment. Participants included a diverse sample of 243 preschool children (Mage = 4.6 years) and their mothers across two measurement occasions spaced 2 years apart. Three forms of risky involvement (i.e., cautious, caregiving, and coercive) were identified using maternal narratives describing children's emotional and behavioral reactivity during and immediately following interparental conflict. Utilizing a multimethod, multi-informant design, findings revealed that each form of involvement prospectively predicted unique configurations of children's developmental outcomes. Greater coercive involvement was associated with higher levels of externalizing problems, callous and unemotional traits, and extraversion. Higher levels of caregiving involvement were linked with greater separation anxiety. Finally, cautious involvement predicted more separation anxiety and social withdrawal.

Maternal and paternal unsupportive parenting and children's externalizing symptoms: The mediational role of children's attention biases to negative emotion.

This study examined children's duration of attention to negative emotions (i.e., anger, sadness, fear) as a mediator of associations among maternal and paternal unsupportive parenting and children's externalizing symptoms in a sample of 240 mothers, fathers, and their preschool children (Mage = 4.64 years). The multimethod, multi-informant design consisted of three annual measurement occasions. Analysis of maternal and paternal unsupportive parenting as predictors in latent difference changes in children's affect-biased attention and behavior problems indicated that children's attention to negative emotions mediated the specific association between maternal unsupportive parenting and children's subsequent increases in externalizing symptoms. Maternal unsupportive parenting at Wave 1 predicted decreases in children's attention to negative facial expressions of adults from Wave 1 to 2. Reductions in children's attention to negative emotion, in turn, predicted increases in their externalizing symptoms from Wave 1 to 3. Additional tests of children's fearful distress and hostile responses to parental conflict as explanatory mechanisms revealed that increases in children's fearful distress reactivity from Wave 1 to 2 accounted for the association between maternal unsupportive parenting and concomitant decreases in their attention to negative emotions. Results are discussed in the context of information processing models of family adversity and developmental psychopathology.

Defense Suppression through Interplant Communication Depends on the Attacking Herbivore Species.

In response to herbivory, plants emit volatile compounds that play important roles in plant defense. Herbivore-induced plant volatiles (HIPVs) can deter herbivores, recruit natural enemies, and warn other plants of possible herbivore attack. Following HIPV detection, neighboring plants often respond by enhancing their anti-herbivore defenses, but a recent study found that herbivores can manipulate HIPV-interplant communication for their own benefit and suppress defenses in neighboring plants. Herbivores induce species-specific blends of HIPVs and how these different blends affect the specificity of plant defense responses remains unclear. Here we assessed how HIPVs from zucchini plants (Cucurbita pepo) challenged with different herbivore species affect resistance in neighboring plants. Volatile "emitter" plants were damaged by one of three herbivore species: saltmarsh caterpillars (Estigmene acrea), squash bugs (Anasa tristis), or striped cucumber beetles (Acalymma vittatum), or were left as undamaged controls. Neighboring "receiver" plants were exposed to HIPVs or control volatiles and then challenged by the associated herbivore species. As measures of plant resistance, we quantified herbivore feeding damage and defense-related phytohormones in receivers. We found that the three herbivore species induced different HIPV blends from squash plants. HIPVs induced by saltmarsh caterpillars suppressed defenses in receivers, leading to greater herbivory and lower defense induction compared to controls. In contrast, HIPVs induced by cucumber beetles and squash bugs did not affect plant resistance to subsequent herbivory in receivers. Our study shows that herbivore species identity affects volatile-mediated interplant communication in zucchini, revealing a new example of herbivore defense suppression through volatile cues.

Chemical Cues from Entomopathogenic Nematodes Vary Across Three Species with Different Foraging Strategies, Triggering Different Behavioral Responses in Prey and Competitors.

Chemical cues play important roles in predator-prey interactions. Semiochemicals can aid predator foraging and alert prey organisms to the presence of predators. Previous work suggests that predator traits differentially influence prey behavior, however, empirical data on how prey organisms respond to chemical cues from predator species with different hunting strategies, and how foraging predators react to cues from potential competitors, is lacking. Furthermore, most research in this area has focused on aquatic and aboveground terrestrial systems, while interactions among belowground, soiling-dwelling organisms have received relatively little attention. Here, we assessed how chemical cues from three species of entomopathogenic nematodes (EPNs), each with a different foraging strategy, influenced herbivore (cucumber beetle) and natural enemy (EPN) foraging behavior. We predicted these cues could serve as chemical indicators of increased predation risk, prey availability, or competition. Our findings revealed that foraging cucumber beetle larvae avoided chemical cues from Heterorhabditis bacteriophora (active-foraging cruiser EPNs), but not Steinernema carpocapsae (ambusher EPNs) or Steinernema riobrave (intermediate-foraging EPNs). In contrast, foraging H. bacteriophora EPNs were attracted to cues produced by the two Steinernema species but not conspecific cues. Notably, the three EPN species produced distinct blends of olfactory cues, with only a few semi-conserved compounds across species. These results indicate that a belowground insect herbivore responds differently to chemical cues from different EPN species, with some EPN species avoiding prey detection. Moreover, the active-hunting EPNs were attracted to heterospecific cues, suggesting these cues indicate a greater probability of available prey, rather than strong interspecific competition.

The Vestiges of Childhood Interparental Conflict: Adolescent Sensitization to Recent Interparental Conflict.

This study examined whether childhood interparental conflict moderated the mediational pathway involving adolescent exposure to interparental conflict, their negative emotional reactivity to family conflict, and their psychological problems in a sample of 235 children (Mage  = 6 years). Significant moderated-mediation findings indicated that the mediational path among Wave 4 interparental conflict during adolescence, change in youth negative reactivity (Waves 4-5), and their psychological problems (Waves 4-6) was significant for teens who experienced low, rather than high, levels of childhood interparental conflict (Waves 1-3). Supporting the stress sensitization model, analyses showed that adolescents exposed to high interparental conflict during childhood evidenced greater increases in negative reactivity than their peers when recent parental conflicts were mild.

Technological Advances to Address Current Issues in Entomology: 2020 Student Debates.

The 2020 Student Debates of the Entomological Society of America (ESA) were live-streamed during the Virtual Annual Meeting to debate current, prominent entomological issues of interest to members. The Student Debates Subcommittee of the National ESA Student Affairs Committee coordinated the student efforts throughout the year and hosted the live event. This year, four unbiased introductory speakers provided background for each debate topic while four multi-university teams were each assigned a debate topic under the theme 'Technological Advances to Address Current Issues in Entomology'. The two debate topics selected were as follows: 1) What is the best taxonomic approach to identify and classify insects? and 2) What is the best current technology to address the locust swarms worldwide? Unbiased introduction speakers and debate teams began preparing approximately six months before the live event. During the live event, teams shared their critical thinking and practiced communication skills by defending their positions on either taxonomical identification and classification of insects or managing the damaging outbreaks of locusts in crops.

Improved clinical outcomes among persons with HIV who quit smoking.

Quitting smoking among people living with HIV/AIDS (PLWHA) is a priority. However, PLWHA and clinicians working with PLWHA are reluctant to use tobacco use treatments out of concern that smoking cessation can diminish anti-retroviral therapy (ART) adherence and quality of life (QoL) and increase psychiatric symptoms. This secondary analysis from a placebo-controlled varenicline trial for tobacco dependence among PLWHA (N = 179) examined if smoking cessation at the end of treatment (EOT) was associated with changes in ART adherence, QoL, anxiety and depression symptoms, and varenicline side effects. ART adherence was not affected by smoking cessation (p > 0.05), remaining ≥98% for all participants. Across 8 QoL subscales, 7 remained unchanged over time across smokers and abstainers; side effects were not associated with cessation. Controlling for baseline smoking rate, adherence to varenicline/placebo and counseling, and treatment arm, participants who had quit smoking at EOT reported a significant reduction in depression (ß = -1.657, 95% CI: -2.893, -0.422, p = .009) and anxiety (ß = -1.434, 95% CI: -2.812, -0.56, p = .041) and increased life satisfaction (ß = 0.88, 95% CI: 0.21, 3.275, p = .027). When PLWHA quit smoking they may not experience adverse clinical outcomes including ART non-adherence and may experience beneficial psychological effects, supporting the use of FDA-approved smoking cessation treatments among PLWHA.

The interplay of polygenic plasticity and adrenocortical activity as sources of variability in pathways among family adversity, youth emotional reactivity, and psychological problems.

This study examined the interplay between a polygenic composite and cortisol activity as moderators of the mediational pathway among family adversity, youth negative emotional reactivity to family conflict, and their psychological problems. The longitudinal design contained three annual measurement occasions with 279 adolescents (Mean age = 13.0 years) and their parents. Latent difference score analyses indicated that observational ratings of adversity in interparental and parent-child interactions at Wave 1 predicted increases in a multimethod, multi-informant assessment of youth negative emotional reactivity to family conflict from Waves 1 to 2. Changes in youth negative emotional reactivity, in turn, predicted increases in a multi-informant (i.e., parents, adolescent, and teacher) assessment of psychological problems from Waves 1 to 3. Consistent with differential susceptibility theory, the association between family adversity and negative emotional reactivity was stronger for adolescents who carried more sensitivity alleles in a polygenic composite consisting of 5-HTTLPR, DRD4 VNTR, and BDNF polymorphisms. Analyses of adolescent cortisol in the period surrounding a family disagreement task at Wave 1 revealed that overall cortisol output, rather than cortisol reactivity, served as an endophenotype of the polygenic composite. Overall cortisol output was specifically associated with polygenic plasticity and moderated the association between family adversity and youth negative emotional reactivity in the same for better or for worse manner as the genetic composite. Finally, moderator-mediated-moderation analyses indicated that the moderating role of the polygenic plasticity composite was mediated by the moderating role of adolescent cortisol output in the association between family adversity and their emotional reactivity.

Macroergonomic factors in the patient work system: examining the context of patients with chronic illness.

Human factors/ergonomics recognises work as embedded in and shaped by levels of social, physical and organisational context. This study investigates the contextual or macroergonomic factors present in the health-related work performed by patients. We performed a secondary content analysis of findings from three studies of the work of chronically ill patients and their informal caregivers. Our resulting consolidated macroergonomic patient work system model identified 17 factors across physical, social and organisational domains and household and community levels. These factors are illustrated with examples from the three studies and discussed as having positive, negative or varying effects on health and health behaviour. We present three brief case studies to illustrate how macroergonomic factors combine across domains and levels to shape performance in expected and unexpected ways. Findings demonstrate not only the importance of context for patients' health-related activities but also specific factors to consider in future research, design and policy efforts. Practitioner Summary: Health-related activities of patients are embedded in and shaped by levels of social, physical and organisational context. This paper combined findings from three studies to specify 17 contextual or macroergonomic factors in home- and community-based work systems of chronically ill patients. These factors have research, design and policy implications.

Mechanisms of Communicating Health Information Through Facebook: Implications for Consumer Health Information Technology Design.

BACKGROUND: Consumer health information technology (IT) solutions are designed to support patient health management and have the ability to facilitate patients' health information communication with their social networks. However, there is a need for consumer health IT solutions to align with patients' health management preferences for increased adoption of the technology. It may be possible to gain an understanding of patients' needs for consumer health IT supporting their health information communication with social networks by explicating how they have adopted and adapted social networking sites, such as Facebook, for this purpose. OBJECTIVE: Our aim was to characterize patients' use of all communication mechanisms within Facebook for health information communication to provide insight into how consumer health IT solutions may be better designed to meet patients' communication needs and preferences. METHODS: This study analyzed data about Facebook communication mechanisms use from a larger, three-phase, sequential, mixed-methods study. We report here on the results of the study's first phase: qualitative interviews (N=25). Participants were over 18, used Facebook, were residents or citizens of the United States, spoke English, and had a diagnosis consistent with type 2 diabetes. Participants were recruited through Facebook groups and pages. Participant interviews were conducted via Skype or telephone between July and September 2014. Data analysis was grounded in qualitative content analysis and the initial coding framework was informed by the findings of a previous study. RESULTS: Participants' rationales for the use or disuse of a particular Facebook mechanism to communicate health information reflected six broad themes: (1) characteristics and circumstances of the person, (2) characteristics and circumstances of the relationship, (3) structure and composition of the social network, (4) content of the information, (5) communication purpose, and (6) attributes of the technology. CONCLUSIONS: The results of this study showed that participants consider multiple factors when choosing a Facebook mechanism for health information communication. Factors included what information they intended to share, what they were trying to accomplish, attributes of technology, and attributes and communication practices of their social networks. There is a need for consumer health IT that allows for a range of choices to suit the intersectionality of participants' rationales. Technology that better meets patients' needs may lead to better self-management of health conditions, and therefore, improve overall health outcomes.

Metal switch-controlled myosin II from Dictyostelium discoideum supports closure of nucleotide pocket during ATP binding coupled to detachment from actin filaments.

G-proteins, kinesins, and myosins are hydrolases that utilize a common protein fold and divalent metal cofactor (typically Mg(2+)) to coordinate purine nucleotide hydrolysis. The nucleoside triphosphorylase activities of these enzymes are activated through allosteric communication between the nucleotide-binding site and the activator/effector/polymer interface to convert the free energy of nucleotide hydrolysis into molecular switching (G-proteins) or force generation (kinesins and myosin). We have investigated the ATPase mechanisms of wild-type and the S237C mutant of non-muscle myosin II motor from Dictyostelium discoideum. The S237C substitution occurs in the conserved metal-interacting switch-1, and we show that this substitution modulates the actomyosin interaction based on the divalent metal present in solution. Surprisingly, S237C shows rapid basal steady-state Mg(2+)- or Mn(2+)-ATPase kinetics, but upon binding actin, its MgATPase is inhibited. This actin inhibition is relieved by Mn(2+), providing a direct and experimentally reversible linkage of switch-1 and the actin-binding cleft through the swapping of divalent metals in the reaction. Using pyrenyl-labeled F-actin, we demonstrate that acto·S237C undergoes slow and weak MgATP binding, which limits the rate of steady-state catalysis. Mn(2+) rescues this effect to near wild-type activity. 2'(3')-O-(N-Methylanthraniloyl)-ADP release experiments show the need for switch-1 interaction with the metal cofactor for tight ADP binding. Our results are consistent with strong reciprocal coupling of nucleoside triphosphate and F-actin binding and provide additional evidence for the allosteric communication pathway between the nucleotide-binding site and the filament-binding region.

Deficiency of huntingtin has pleiotropic effects in the social amoeba Dictyostelium discoideum.

Huntingtin is a large HEAT repeat protein first identified in humans, where a polyglutamine tract expansion near the amino terminus causes a gain-of-function mechanism that leads to selective neuronal loss in Huntington's disease (HD). Genetic evidence in humans and knock-in mouse models suggests that this gain-of-function involves an increase or deregulation of some aspect of huntingtin's normal function(s), which remains poorly understood. As huntingtin shows evolutionary conservation, a powerful approach to discovering its normal biochemical role(s) is to study the effects caused by its deficiency in a model organism with a short life-cycle that comprises both cellular and multicellular developmental stages. To facilitate studies aimed at detailed knowledge of huntingtin's normal function(s), we generated a null mutant of hd, the HD ortholog in Dictyostelium discoideum. Dictyostelium cells lacking endogenous huntingtin were viable but during development did not exhibit the typical polarized morphology of Dictyostelium cells, streamed poorly to form aggregates by accretion rather than chemotaxis, showed disorganized F-actin staining, exhibited extreme sensitivity to hypoosmotic stress, and failed to form EDTA-resistant cell-cell contacts. Surprisingly, chemotactic streaming could be rescued in the presence of the bivalent cations Ca(2+) or Mg(2+) but not pulses of cAMP. Although hd(-) cells completed development, it was delayed and proceeded asynchronously, producing small fruiting bodies with round, defective spores that germinated spontaneously within a glassy sorus. When developed as chimeras with wild-type cells, hd(-) cells failed to populate the pre-spore region of the slug. In Dictyostelium, huntingtin deficiency is compatible with survival of the organism but renders cells sensitive to low osmolarity, which produces pleiotropic cell autonomous defects that affect cAMP signaling and as a consequence development. Thus, Dictyostelium provides a novel haploid organism model for genetic, cell biological, and biochemical studies to delineate the functions of the HD protein.

Beyond traditional advertisements: leveraging Facebook's social structures for research recruitment.

BACKGROUND: Obtaining access to a demographically and geographically diverse sample for health-related research can be costly and time consuming. Previous studies have reported mixed results regarding the potential of using social media-based advertisements to overcome these challenges. OBJECTIVE: Our aim was to develop and assess the feasibility, benefits, and challenges of recruiting for research studies related to consumer health information technology (IT) by leveraging the social structures embedded in the social networking platform, Facebook. METHODS: Two recruitment strategies that involved direct communication with existing Facebook groups and pages were developed and implemented in two distinct populations. The first recruitment strategy involved posting a survey link directly to consenting groups and pages and was used to recruit Filipino-Americans to a study assessing the perceptions, use of, and preferences for consumer health IT. This study took place between August and December 2013. The second recruitment strategy targeted individuals with type 2 diabetes and involved creating a study-related Facebook group and asking administrators of other groups and pages to publicize our group to their members. Group members were then directly invited to participate in an online pre-study survey. This portion of a larger study to understand existing health management practices as a foundation for consumer health IT design took place between May and June 2014. In executing both recruitment strategies, efforts were made to establish trust and transparency. Recruitment rate, cost, content of interaction, and characteristics of the sample obtained were used to assess the recruitment methods. RESULTS: The two recruitment methods yielded 87 and 79 complete responses, respectively. The first recruitment method yielded a rate of study completion proportionate to that of the rate of posts made, whereas recruitment successes of the second recruitment method seemed to follow directly from the actions of a subset of administrators. Excluding personnel time, the first recruitment method resulted in no direct costs, and the second recruitment method resulted in a total direct cost of US $118.17. Messages, posts, and comments received using both recruitment strategies reflected ten themes, including appreciation, assistance, clarification, concerns, encouragement, health information, interest, promotion, solicitations, and support. Both recruitment methods produced mixed results regarding sample representativeness with respect to characteristics such as gender, race, and ethnicity. CONCLUSIONS: The results of the study demonstrate that leveraging the social structures of Facebook for health-related research was feasible for obtaining small samples appropriate for qualitative research but not for obtaining large samples needed for quantitative research. The content of interactions with members of the target population prompted ethical deliberations concerning suitable target communities and appropriate boundaries between researchers and participants. Widespread replication of this method would benefit from a broad discussion among researchers, social media users, social media companies, and experts in research ethics to address appropriate protocols for such interactions.

Parent-child boundary dissolution and children's psychological difficulties: A meta-analytic review.

Boundary dissolution has broadly been defined as the breakdown of boundaries and loss of psychological distinctiveness in the parent-child subsystem. Qualitative reviews have highlighted the developmental and clinical value of examining boundary dissolution as a multidimensional construct. Though prior work suggests patterns share minimal variance, research has yet to quantitatively synthesize the weighted effect of distinct patterns. The primary aim of this meta-analysis was to aggregate empirical research on associations between boundary dissolution patterns and children's internalizing and externalizing symptoms. Four patterns of boundary dissolution were identified across developmental, clinical, and family systems literatures: (a) enmeshment-entanglement and blurring of the intergenerational parent-child boundary through psychologically controlling and intrusive behaviors, (b) disorganization-chaotic parent-child boundary (e.g., inexplicable, contradictory behaviors, and responses) reflecting no coherent pattern of relating, (c) caregiving-child functions as a caregiver providing parents with instrumental and emotional support and guidance, and (d) coerciveness-child operates as a disciplinarian or authoritarian to intimidate and control parents. The meta-analysis reviewed 478 studies. Although each boundary dissolution pattern was associated with internalizing and externalizing symptoms, weighted effects across patterns significantly varied in magnitude. Regarding externalizing symptoms, the weighted effect of enmeshment was stronger relative to the weighted effect of caregiving. Turning to internalizing symptoms, the weighted effect of enmeshment was stronger than the weighted effect of caregiving and coerciveness. Additionally, the weighted effect of disorganization was stronger than the weighted effect of caregiving. The robustness of weighted effects depended on child, contextual, and methodological characteristics as well as time lag. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The COVID-19 Lived Experience Through the Eyes of Nursing and Social Work Students.

Purpose: The purpose of this study was to explore the lived experiences of nursing and social work students who were taking courses during the COVID-19 pandemic. Focus group discussions gave students a chance to express the pandemic's effects on their education and life. Methods: A hermeneutic phenomenological approach using Van Manen's Four Lifeworld Existentials guided this study. Using an open-ended format, interviews were conducted in 6 small groups ranging from 2 to 9 individuals, in person or via Zoom. The study was conducted from May to August 2022 in a university setting with 23 participants. Results: Ten existential themes emerged: Being Behind, Groundhog Day, Trying to Keep Up, Loss of Community, Fear of COVID, Being Alone, What is Self-Care?, Is This Career Right for Me?, What is Healthy?, and Access to Counseling. Conclusions: Participants indicated that the COVID-19 pandemic negatively impacted educational delivery, limiting learning opportunities and increasing feelings of isolation, stress, and anxiety. Implications for Education and the Future Workforce: Projected health-care workforce shortages may be exacerbated by students departing from the health-care professions as a result of increased burnout. Resilience training while in school is necessary to help promote coping, self-care strategies, and retention in the health-care professions.

A process model of parental executive functioning as a spillover mechanism linking interparental conflict and parenting difficulties across parenting domains.

There is a well-documented interdependency between destructive interparental conflict (IPC) and parenting difficulties (i.e., spillover effect), yet little is known about the mechanisms that "carry" spillover between IPC and parenting. Guided by a cascade model framework, the current study used a longitudinal, multimethod, multi-informant design to examine a process model of spillover that tested whether parental executive functioning (working memory, cognitive flexibility, inhibitory control) served as a mediator of the prospective associations between IPC and subsequent changes in parenting over a 2-year period. Mothers and fathers were separated into differentiated models and multiple domains of parenting were examined (i.e., authoritarian discipline and scaffolding behavior). Participants included 231 families (both mothers and fathers of preschoolers). Race was reported as White (62%), Black (21%), Mixed (8%), Asian (3%), or Other (6%) and 14% considered their ethnicity to be Hispanic/Latino. Median household income was $65,000. Results indicated that for fathers, IPC indirectly predicted domain-general parenting difficulties (increased authoritarian parenting and decreased scaffolding) via deficits in paternal cognitive flexibility (but not inhibitory control or working memory). In mothers, IPC directly predicted domain-specific parenting difficulties (decreased scaffolding only) that did not operate via maternal executive functions. Notably, these effects occurred over and above the influence of parental socioeconomic status. This study constitutes a first step toward documenting parental executive functioning as a mechanism underlying the spillover of IPC to the parent-child relationship. Family interventions intended to interrupt IPC spillover should emphasize father involvement and consider targeting parental executive functions as change mechanisms.
