Behavioral Outcomes Research Articles

Research participant perceptions of personal utility in disclosure of individual research results from genomic analysis.

This article elaborates research participant perspectives on the communication of individual research results from genomic analyses. While most analyses focus on how to communicate results from the perspectives of clinicians or researchers, there is insufficient data on user perspectives and how this information may be used, valued, and interpreted by patients and their families. The concept of personal utility, which considers factors related to quality of life, including on how information may impact the person's future decisions, has been shown to be particularly relevant to understand research participant perspectives and to move beyond clinical and analytic utility factors such as mortality and morbidity. This article draws from qualitative research of research participants awaiting genomic results in the case of sudden cardiac death. Our results show perspectives of personal utility in communication of genomic results, including cognitive, behavioral, and affective outcomes. Cognitive outcomes include gain of information, improved knowledge of etiology and inheritance characteristics, and curiosity for what might be found. Behavioral outcomes include being able to plan life decisions, while affective outcomes include various coping strategies used. We will also discuss the value of knowing negative results and incidental findings from the research participant's perspective. This contribution gives suggestions on best practices to guide genome analysis returns, including incorporating participant wishes on individualized communication at the consent stage; developing relational autonomy approaches; and engaging them throughout the research trajectory.

The influence of positivity and self-efficacy beliefs on family functioning among young adults in Italy and Colombia.

Research suggests that positivity and self-efficacy beliefs may impact adaptive behavior and developmental outcomes, such as social adjustment and subjective wellbeing. The present study explored the effect of positive dimensions (positivity and self-efficacy beliefs) and individual characteristics (gender, type of country, age, and sexual orientation) on family cohesion and flexibility in a group of Colombian and Italian young adults. An online survey was administered to 949 Colombian and 2,073 Italian people aged between 18 and 40 years (M age = 24.3; SDage = 4.5; 67% women). A mediational model was performed to test the influence of positivity on family functioning via the mediational role of self-efficacy beliefs, analyzing the moderated effects of gender, type of country, sexual orientation, and age. Filial self-efficacy mediated the effect of positivity on family functioning, showing stronger paths in men and Colombian participants than in women and Italian counterparts. Regulatory self-efficacy mediated the associations between positivity and family functioning for both genders and types of countries. The results suggest that positivity and self-efficacy beliefs may allow families to engage in more adaptive family functioning across countries and genders. Further research should focus on implications from a cross-national perspective to examine other culture-specific factors that may impact family adjustment.

The effects of technostressors on work and non-work outcomes in hybrid work

ABSTRACT While employees use information and communication technology (ICT) to support hybrid work, such ICT can result in technostressors. Drawing upon the challenge-hindrance stressor framework, we conceptualise availability and efficient communication as the challenge technostressors, and interruption as the hindrance technostressor. We then develop a theoretical model based on conservation of resources theory to assess their effects on behavioural and psychological outcomes in both work and non-work domains. Survey data were collected from 437 Chinese employees who engaged in hybrid work. The results show that availability and efficient communication enhance perceived location/schedule flexibility, while interruption reduces perceived schedule flexibility. Furthermore, while perceived location flexibly only increased work performance, perceived schedule flexibility increased work/non-work performance and reduced work/non-work exhaustion. Lastly, significant differences were found between those under high and those under low hybrid work. Our study contributes to the literature by clarifying the antecedents and outcomes of location/schedule flexibility in the context of hybrid work. Our study provides important practical suggestions related to the management of hybrid work.

Impacts on Atlantic Killifish from Neurotoxicants: Genes, Behavior, and Population-Relevant Outcomes.

Molecular, cellular, and organismal alterations are important descriptors of toxic effects, but our ability to extrapolate and predict ecological risks is limited by the availability of studies that link measurable end points to adverse population relevant outcomes such as cohort survival and growth. In this study, we used laboratory gene expression and behavior data from two populations of Atlantic killifish Fundulus heteroclitus [one reference site (SCOKF) and one PCB-contaminated site (NBHKF)] to inform individual-based models simulating cohort growth and survival from embryonic exposures to environmentally relevant concentrations of neurotoxicants. Methylmercury exposed SCOKF exhibited brain gene expression changes in the si:ch211-186j3.6, si:dkey-21c1.4, scamp1, and klhl6 genes, which coincided with changes in feeding and swimming behaviors, but our models simulated no growth or survival effects of exposures. PCB126-exposed SCOKF had lower physical activity levels coinciding with a general upregulation in nucleic and cellular brain gene sets (BGS) and downregulation in signaling, nucleic, and cellular BGS. The NBHKF, known to be tolerant to PCBs, had altered swimming behaviors that coincided with 98% fewer altered BGS. Our models simulated PCB126 decreased growth in SCOKF and survival in SCOKF and NBHKF. Overall, our study provides a unique demonstration linking molecular and behavioral data to develop quantitative, testable predictions of ecological risk.

Mastery performance‐goal orientation objective test: goal orientation profiles

AbstractThe Mastery Performance‐Goal Orientation Test (MP‐GOT) assesses performance‐ and mastery‐orientation along a single bipolar dimension. In Study 1 (n = 198) we explored its psychometric properties and determined whether its results were related to learning. In addition, we employed Latent Profile Analysis to explore goal orientation profiles. In Study 2 (n = 1689) we explored whether goal orientation scores were related to cooperation and whether the goal orientation profiles identified in Study 1 were replicated. In both studies, reliability of the MP‐GOT was high, and a 4‐profile solution was retained. Mastery‐oriented participants tend to obtain higher learning scores (Study 1) and higher cooperation scores (Study 2). MP‐GOT has the potential to be a useful instrument for measuring goal orientation and its relation to relevant behavioral outcomes.

The foundations and applications of teaching environmental problems: paradigms, learning domains, worldviews, and how they interact

While environmental problems are urgent in modern society, they are especially difficult to tackle because of their normative and politically controversial nature. Universities may choose different theoretical paradigms for the teaching of environmental problems. However, limited theoretical and/or practical analysis has been undertaken of the theoretical and normative paradigms underlying education on environmental problems. How do we know if educational approaches sufficiently equip students to deal with environmental issues? This article provides a taxonomy for mapping both environmental paradigms and learning outcomes, allowing for a thematic content analysis of the programs of a Dutch university that focuses on environmental problems. The main findings are that, while the course guides are overall highly internally coherent, there are disciplinary silos where the different disciplines teach from different paradigmatic presuppositions. Furthermore, the programs are very cognitive-centered, leaving little room for affective, social, and behavioral learning outcomes, despite the importance of these in higher education. This cognitive bias is relevant for all paradigmatic outlooks, but especially for the more mechanistically oriented paradigms. While understandable from the substance of these paradigms, multimodality in pedagogy and learning outcomes is needed for a comprehensive education.

Scheduled feeding improves behavioral outcomes and reduces inflammation in a mouse model of Fragile X syndrome.

Fragile X syndrome (FXS) is a neurodevelopmental disorder caused by the abnormal expansion of CGG repeats in the fragile X mental retardation 1 (FMR1) gene. Many FXS patients experience sleep disruptions, and we sought to explore these symptoms along with the possible benefits of a scheduled feeding intervention using the Fmr1 knockout (KO) mouse model. These mutants displayed clear evidence for sleep and circadian disturbances including delay in the onset of sleep and fragmented activity rhythms with increases in cycle-to-cycle variability. The Fmr1 KO mice exhibited deficits in their circadian behavioral response to light with reduced masking, longer time to resetting to shifts in the LD cycle, altered synchronization to a skeleton photoperiod and lower magnitude light-induced phase shifts of activity rhythms. Investigation of the retinal input to the surprachiasmatic nucleus (SCN) with the neurotracer cholera toxin (β subunit) and quantification of the light-evoked cFos expression in the SCN revealed an abnormal retinal innervation of the SCN in the Fmr1 KO, providing a possible mechanistic explanation for the observed behavioral deficits. Interestingly, disruptions in social and repetitive behavior correlated with sleep duration and fragmentation. Understanding the nature of the deficits, we decided to apply a scheduled feeding regimen (6-hr/18-hr feed/fast cycle) as a circadian-based strategy to boast circadian rhythms independently of light. This intervention significantly improved the activity rhythms and sleep in the mutants. Strikingly, the scheduled feeding ameliorated social interactions and reduced repetitive behaviors as well as the levels of Interferon-gamma and Interleukin-12 in the Fmr1 KO mutants, suggesting that timed eating may be an effective way to reduce inflammation. Collectively, this work adds support to efforts to develop circadian based interventions to help with symptoms of neurodevelopmental disorders.

Cognitive effects of early life exposure to PCBs: Sex-specific behavioral, hormonal and neuromolecular mechanisms involving the brain dopamine system.

Endocrine-disrupting chemicals (EDCs) are environmental toxicants that disrupt hormonal and neurodevelopmental processes. Among these chemicals, polychlorinated biphenyls (PCBs) are particularly concerning due to their resistance to biodegradation and tendency to bioaccumulate. PCBs affect neurodevelopmental function and disrupt the brain's dopamine (DA) system, which is crucial for attentional, affective, and reward processing. These disruptions may contribute to the rising prevalence of DA-mediated neuropsychiatric disorders such as ADHD, depression, and substance use disorders. Notably, these behaviors are sexually dimorphic, in part due to differences in sex hormones and their receptors, which are targets of estrogenic PCBs. Therefore, this study determined effects of early life PCB exposure on behaviors and neurochemistry related to potential disruption of dopaminergic signaling. Male and female Sprague Dawley rats were exposed to PCBs or vehicle perinatally and then underwent a series of behavioral tests, including the sucrose preference test to measure affect, conditioned orienting to assess incentive-motivational phenotype, and attentional set-shifting to evaluate cognitive flexibility and response latency. Following these tests, rats were euthanized, and we measured serum estradiol (E2), midbrain DA cells, and gene expression in the midbrain. Female rats exposed perinatally to A1221 exhibited decreased sucrose preference, and both male and female A1221 rats had reduced response latency in the attentional set-shifting task compared to vehicle counterparts. Conditioned orienting, serum estradiol (E2), and midbrain DA cell numbers were not affected in either sex; however, A1221-exposed male rats displayed higher expression of estrogen receptor alpha ( Esr1 ) in the midbrain and non-significant effects on other DA-signaling genes. Additionally, E2 uniquely predicted behavioral outcomes and DAergic cell numbers in A1221-exposed female rats, whereas DA signaling genes were predictive of behavioral outcomes in males. These data highlight sex-specific effects of A1221 on neuromolecular and behavioral phenotypes.

Physical and Social Servicescape: Impact on Customer Affection and Behavior at Full-Service Restaurants

ABSTRACT This study utilizes Stimulus Organism Response (SOR) theory to examine how customer, employee, and physical servicescape affect consumer behavior in full-service restaurants, as well as how customer affection mediates, and gender moderates these effects. We managed to collect 308 valid responses, which we further analyzed through structural equation modeling. The data supported the idea that customers, employees, and physical servicescape favorably affect customer affection, which in turn influences revisit intentions and WoM. Customer affection also mediates the effects of the three servicescape dimensions on WoM and revisit intentions. Males were more affected by employee servicescape and customer affection. Whereas females had a larger effect of customer servicescape on customer affection; other differences were insignificant. Within the SOR theory, we added customer affection as a mediator and gender as a moderator between servicescapes’ dimensions and behavioral outcomes (e.g. WoM and revisit intentions).

Alterations in cortical and subcortical neuroanatomy and associations with behavior in females with fragile X syndrome.

To address substantial gaps in the literature on neuroanatomical variations in females with fragile X syndrome (FXS). Surface-based modeling techniques were applied to the magnetic resonance imaging of 45 females with FXS (mean age = 10 years 9 months, range 6 years-16 years 4 months, SD = 2 years 9 months) and 33 age-matched and developmentally matched females without FXS to elucidate differences in cortical gray matter volume, surface area, and thickness. Gray matter volumes in subcortical regions were examined to ascertain differences in subcortical volume. In females with FXS, cortical volume was greater bilaterally in the occipital pole and smaller in the right postcentral gyrus. Seven regions demonstrated lower surface area in participants with FXS, while cortical thickness was significantly greater over the posterior and medial surfaces in the group with FXS. Subcortical region of interest analyses demonstrated greater volume in the caudate nucleus, globus pallidus, and nucleus accumbens in the group with FXS. Global gray matter volume, pial thickness, and surface area were associated with behavioral outcomes in the group with FXS but not in the comparison group. Females with FXS demonstrated unique cortical and subcortical gray matter anatomy relative to a matched comparison group. These findings may be relevant to the pathogenesis of the FXS behavioral phenotype and provide insights into behavioral interventions targeted to this population.

Differential Impact of Adolescent or Adult Stress on Behavior and Cortical Parvalbumin Interneurons and Perineuronal Nets in Male and Female Mice.

Stress has become a common public health concern, contributing to the rising prevalence of psychiatric disorders. Understanding the impact of stress considering critical variables, such as age, sex, and individual differences, is of the utmost importance for developing effective intervention strategies. Stress effects (daily footshocks for 10 days) during adolescence (postnatal day [PND] 31-40) and adulthood (PND 65-74) were investigated on behavioral outcomes and parvalbumin (PV)-expressing GABAergic interneurons and their associated perineuronal nets (PNNs) in the prefrontal cortex of male and female mice 5 weeks post stress. In adulthood, adolescent stress induced behavioral alterations in male mice, including anxiety-like behaviors, social deficits, cognitive impairments, and altered dopamine system responsivity. Applying integrated behavioral z-score analysis, we identified sex-specific differences in response to adolescent stress, with males displaying greater vulnerability than females. Furthermore, adolescent-stressed male mice showed decreased PV+ and PNN+ cell numbers and PV+/PNN+ colocalization, while in females, adolescent stress reduced prefrontal PV+/PNN+ colocalization in the prefrontal cortex. Further analysis identified distinct behavioral clusters, with certain females demonstrating resilience to adolescent stress-induced deficits in sociability and PV+ cell number. Adult stress in male and female mice did not cause long-lasting changes in behavior and PV+ and PNN+ cell number. Our findings indicate that the timing of stress, sex, and individual variabilities seem to be determinants for the development of behavioral changes associated with psychiatric disorders, particularly in male mice during adolescence.

Outcomes that Matter to Youth and Families in Behavioral Health Services.

Patient-centered outcomes research helps youth and families using behavioral health services make informed decisions about treatments to help them achieve the outcomes most important to them. However, there are few efforts to identify the outcomes valued by youth and families systematically. This project aimed to support the development of behavioral health services that deliver outcomes valued by families by identifying the outcomes that youth and young adults with behavioral health needs and caregivers say matter most to them. We engaged 34 youth and young adults (YYA) with behavioral health needs, alongside 42 caregivers from six U.S. regions, in two rounds of one-hour virtual focus groups. The initial round involved participants identifying what they hoped to gain from using behavioral health services for personal, familial, and parental or child well-being and the attributes of positive service experiences. We coded responses using qualitative analytical software, culminating in synthesized reports. Subsequently, the second round entailed participants' review and refinement of initial findings. Across sessions, each group reported the top three outcomes deemed most important for children, YYA, parents, families, and their service experiences. YYA identified being understood by others, improving their interpersonal relationships, and feeling heard as the highest priority behavioral health service outcomes. Caregivers of children and youth with behavioral health needs identified having accessible services that meet their needs, having providers that collaborate effectively with parents and other service systems, and experiencing consistent and continuous behavioral health care for their child as the most important behavioral health service outcomes. Both YYA with behavioral health needs and caregivers of children and youth prioritized gaining the necessary knowledge, resources, and tools to support their or their child's behavioral health. Additionally, both participant groups emphasized the importance of effective communication with providers, within their families, and with peers. Minimizing judgment and stigma from society, providers, and other professionals also emerged as a critical outcome for these groups. It is essential for research and policy development to focus on and cater to the outcomes that are important and valued by YYA and their families to maximize family engagement in care.

Testing an Organizational Implementation Process Model Related to Teachers' Implementation-Related Attitudes and Behaviors: a Multilevel Mediation Analysis.

The effectiveness of school-based universal prevention programs is frequently diminished due to low-quality implementation. Organizational factors support high-quality implementation because of their broad influence across implementers. Conceptually, implementation leadership (i.e., behaviors that prioritize, reward, and support evidence-based practice [EBP] implementation) works to embed a favorable implementation climate (i.e., implementers' collective perceptions that their organization prioritizes, rewards, and support EBP implementation) leading to improved implementation citizenship behavior and attitudes toward EBP. This organizational implementation process model has some empirical support but has not been tested in a multilevel framework or related to hypothesized attitudinal and behavioral outcomes. The sample included 319 teachers across 39 US public elementary schools; all were implementing Schoolwide Positive Behavior Interventions and Supports. Multilevel mediation (level 1 = teacher, level 2 = school) was used to test the indirect association of implementation leadership on implementation-related attitudes and behaviors via implementation climate across two time points (fall and spring). At the school level, the organizational implementation process model was validated related to implementation citizenship behavior, but not attitudes toward EBP. At the teacher level, the process model was validated related to both outcomes, and there was a significant direct effect of implementation leadership on attitudes toward EBP. Developing strong leaders for implementation seems key to achieving high-quality EBP implementation. Implications for schools, principal training, and research are discussed.

Maternal dietary patterns and offspring behavioral problems.

Mental health problems often begin in early childhood and could predict psychiatric and behavioral outcomes. Prenatal factors such as maternal nutrition have an impact on neurodevelopment. This study aims to investigate the association between maternal dietary patterns and emotional and behavioral problems in 4-year-old children. Within a cohort of 205 mother-child pairs, three maternal dietary patterns were identified: 'Sweet and Superfluous', 'Fish and Vegetables' and 'Meat and Cereals'. Child behavior was evaluated by means of the Child Behavior Checklist 1.5-5 (CBCL 1.5-5), the Teacher's Report Form 1.5-5 (TRF 1.5-5), and the Behavior Rating Inventory of Executive Function - Preschool Version (BRIEF-P). Multivariable analysis determined associations between maternal dietary patterns and their children's behavior. Maternal adherence to the 'Sweet and Superfluous' pattern was positively associated with externalizing and depressive problems in children. The 'Meat and Cereals' pattern was linked to a higher risk for attention, hyperactivity and depressive problems as somatic complaints. Conversely, the 'Fish and Vegetables' pattern was associated with a reduced risk of hyperactivity problems. All these associations were more pronounced in girls than in boys. Maternal diet during pregnancy is associated with the emotional and behavioral development of children at 4 years of age. Previous research on prenatal dietary patterns and children's behavior is inconclusive. In our study, children of mothers who had higher intakes of sugar and processed foods during pregnancy were more likely to have emotional and behavioral problems at age 4, especially girls. A high-quality diet characterized by fish and vegetable consumption during pregnancy was associated with reduced anxiety and hyperactivity problems in girls. Our findings highlight the importance of prenatal nutrition for child neurodevelopment.

Should I stay (home) or should I go (party)? Examination of drinking as a mediator of the relationship between alcohol-related social media content and adherence to COVID-19 recommendations among college students.

The COVID-19 pandemic impacted young people's drinking. Yet, despite social gatherings posing a known risk for increased contraction, some college students still congregated to drink. Furthermore, some students posted about these drinking events to their public and/or private social media feeds. It is crucial to understand the relationships between posting alcohol-related content (ARC), drinking and adherence to COVID-19 recommendations because they may have contributed to the spread of the virus. The current interval contingent, 14-day diary study assessed students' (N = 129) public and private ARC; their drinking; percentage of time wearing a mask and social distancing; and number of people they socialised with during drinking events (total crowd size) each day. Multilevel structural equation modelling was employed to examine relationships between ARC posting, drinking and behavioural outcomes. On days in which students posted both public and private ARC, they tended to drink more and in turn, reported attending gatherings with larger crowds. Curiously, on days in which students drank more, they indicated more mask wearing and social distancing, and on days in which students posted more private ARC, they also reported larger crowds. Finally, an indirect effect of drinking on the links between public and private ARC and mask wearing, social distancing and total crowd sizes emerged. Findings revealed students continued to post and drink socially despite the risks, which may have encouraged others within their networks to engage in similar risky behaviours. Future public health crises should balance young people's need for social connection with risk mitigation efforts.

A - 45 Duchenne and Becker Muscular Dystrophy: Sibling Case Studies

Abstract Objective Duchenne Muscular Dystrophy (DMD) is an X-linked recessive neuromuscular condition primarily affecting males. Progressive proximal muscle wasting and weakness is seen and a shortened life span can occur due to cardiac involvement. Becker Muscular Dystrophy (BMD) is a milder form of DMD. Non-progressive cognitive impairment (e.g., lower IQ) in DMD has been well established, while the cognitive profile in BMD is less known. DMD/BMD are caused by mutations in the dystrophin protein. Research suggests that mutations downstream of exon 63 in the DMD gene are associated with poorer cognitive outcomes compared to upstream 1–30. Our cases explore the association between genetic/medical factors upon cognitive and behavioral outcomes, and neuropsychological similarities/differences between DMD and BMD. Method The current sibling case studies include one BMD set (mutations at exon 45–49) and two DMD sets (exon 61–74, and 13, respectively). They are part of a larger IRB-approved research dataset. Notably in DMD set two, the siblings have different biological fathers. Results The BMD siblings have comparable neuropsychological profiles (e.g., below average IQ, academic challenges, attention/executive problems). In DMD set one, one sibling has average intelligence with no academic challenges, while the other sibling has a low average IQ with challenges in math and spelling. In DMD set two, one sibling has intact cognitive functioning, while the other sibling performs well below average across neurocognitive domains. Conclusions Our results indicate variabilities in DMD/BMD, highlighting the contributing role of established factors (e.g., mutation location) and additional non-DMD influences (e.g., genetic contributions from biological father) to understand neuropsychological profiles.

B - 22 Self-Reported Traumatic Brain Injury and its Biopsychosocial Risk Factors in Siblings of Individuals with Neurodevelopmental Conditions

Abstract Objective Siblings of individuals with neurodevelopmental conditions (NDCs) are situated within a complex system of transdiagnostic risk and resilience factors for poor psychosocial, cognitive and behavioral outcomes. Many such factors experienced by NDC siblings overlap with risk for traumatic brain injury (TBI) and correlate with poorer recovery trajectories. Method With data from an online self-report survey, the present study used Bayesian analyses to characterize and compare TBI and biopsychosocial risk factors amongst 632 siblings (207 NDC, 425 controls; mean age 20.54 years, range 10–30, 78.48% female), and examine correlations between clinical, biological, and social determinant of health variables. Results NDC siblings had a higher self-reported lifetime history of TBI compared to controls (14.98% versus 6.35%), with most NDC siblings reporting more than one TBI, and at an earlier mean age. TBI history was associated with psychiatric diagnoses and subclinical NDC features, including hyperactivity and impulsivity, inattention, conduct problems, and autistic traits. Family and structural factors related to TBI included poorer parent–child relationship, NDC diagnoses of autism or fetal alcohol spectrum disorder, minority ethnicity and lower income. Conclusions Findings have important clinical and policy implications for health literacy, TBI education and screening, development of prevention and intervention strategies, and implementation of family support to target social and structural determinants of health impacting NDC sibling wellbeing.

Health-Related Communication of Social Media Influencers: A Scoping Review

ABSTRACT Social media influencers (SMIs) are an essential part of today’s digital media landscape and have the ability to significantly impact the health-related attitudes and behavior of their audiences. Despite an increasing number of studies, research has produced mixed results, and a comprehensive overview of the main findings is lacking. Therefore, the goal of this scoping review was to comprehensively map the literature focusing on SMIs and their health-related communication. Specifically, we analyzed the most frequently studied health topics and social media platforms, the methodological characteristics of the studies, as well as the communication techniques employed by SMIs, and the potential positive and negative effects of their communication on their audience. Additionally, we examined the major research gaps in this area. Altogether, we analyzed n = 116 empirical papers. The results reveal a wide range of different outcomes influenced by SMIs, including both positive and negative changes in health-related attitudes and behavioral intentions among their followers. Furthermore, our findings highlight the need for future research to prioritize experimental and longitudinal studies, investigate actual behavioral outcomes resulting from influencer content exposure, and closely examine the potential negative effects of SMIs’ health-related communication. More attention needs to be paid to health-related misinformation disseminated by SMIs. Lastly, this study identified several highly relevant health topics and social media platforms that should be the focus of future research.

Everyday conversations that impact health communication: developing and validating the everyday family health communication measure

ABSTRACT Research has shown that targeted, or episodic, conversations impact health behavior outcomes, like drinking, smoking, and sex, even later in life during emerging adulthood. However, little is truly known about families that engage in these episodic conversations. Research has speculated that the mundane everyday conversations may influence episodic communication and their subsequent behaviors. Therefore, steps were taken to better understand these everyday, or macro-level, health conversations. Study I operationalizes everyday family health communication that occurs within families to explore the if and why people subsequently engage in episodic health communication using a scale with 35 items developed from prior research. Participants (N = 163) completed a survey, which allowed for several factor analyses to narrow the measure down to 16 items. Study II validates the measure by examining the influence of everyday family health communication on targeted, episodic, health conversations, and health outcomes. Study II included 216 participants who responded to this new measure, as well as items pertaining to episodic communication (e.g. about alcohol or drug use) to assess the effects of everyday family health communication on episodic health communication within families. Results indicate that everyday family health communication was important in understanding family episodic communication about health behaviors and health behavior outcomes.

B - 18 Effect of Automatic Approach Tendency on Neural Dynamics in Heavy Drinkers: an ERP Study

Abstract Objective Automatic alcohol approach/avoidance tendencies play a major role in alcohol dependence, but associated interventions are seen to have negligible effects on relapse prevention due to a limited understanding and lack of focus on modulating associated neuro-cognitive mechanisms. The current work explores the automatic tendencies-based behavioral and event-related potential (ERP) differences and probes into the neurocognitive processes and responsible brain regions. Method The study was conducted in a laboratory setting on 19 heavy drinkers (Alc) and 20 non-drinkers (NAlc) males recruited using snowball sampling, where participants performed an Alcohol Approach-Avoidance Task (AAT), a task for assessing/categorizing participants with automatic approach (AAppr) and avoidance (AAvoi) tendencies toward alcohol during EEG recording. A 2 (group: Alc, NAlc) x 2 (automatic tendencies: approach, avoidance) ANOVA for behavioral outcomes and ANOVA with planned contrasts for Alc and NAlc, and AAppr and AAvoi groups comparisons were performed on early, mid, and late ERP measures. Results The group-tendency interaction significantly influenced behavioral AAT scores. At the neural level, the Alc and NAlc group differences were present at the occipital, parietal, and frontal sites. However, the AAppr and AAvoi group differences were only present at the frontal regions, and prominent for N100–200 and N350–450 amplitudes at the F4 electrode, an electrode sitting over the right dorsolateral prefrontal cortex (dLPFC), responsible for modulating attention, response inhibition, and decision-making processes. Conclusion The results clarify the role of frontal and right dLPFC areas in driving the differences in automatic tendencies by significantly suppressing the neural responses in heavy drinkers with approach but not avoidance tendencies.
