Description
Family adaptation to child developmental disability is a dynamic transactional process that has yet to be tested in a longitudinal, rigorous fashion. In addition, although children with developmental delays frequently have behavior problems, not enough research has examined possible underlying mechanisms in the relation between child developmental delay, adaptation and behavior problems. In the current study, factor analysis examined how best to conceptualize the construct of family adaptation to developmental delay. Also, longitudinal growth curve modeling tested models in which child behavior problems mediated the relation between developmental risk and indices of family adaptation. Participants included 130 typically developing children and their families (Mental Development Index [MDI] > 85) and 104 children with developmental delays and their families (MDI < 85). Data were collected yearly between the ages of three and eight as part of a multi-site, longitudinal investigation examining the interrelations among children's developmental status, family processes, and the emergence of child psychopathology. Results of the current study indicated that adaptation is best conceptualized as a multi-index construct. Different aspects of adaptation changed in unique ways over time, with some facets of adaptation remaining stable while others fluctuated. Child internalizing and externalizing behavior problems were found to decrease over time for both children with developmental delays and typically developing children. Child behavior problems were also found to mediate the relation between developmental risk and family adaptation for over half of the mediation pathways. Significant mediation results indicated that children with developmental delays showed higher early levels of behavior problems, which in turn was associated with more maladaptive adaptation. These findings provide further evidence that families of children with developmental delays experience both positive and more challenging changes in their families over time. This study implies important next steps for research and clinical practice in the area of developmental disability.

Description
When people pick up the phone to call a telephone quitline, they are taking an important step towards changing their smoking behavior. The current study investigated the role of a critical cognition in the cessation process--self-efficacy. Self-efficacy is thought to be influential in behavior change processes including those involved in the challenging process of stopping tobacco use. By applying basic principles of self-efficacy theory to smokers utilizing a telephone quitline, this study advanced our understanding of the nature of self-efficacy in a "real-world" cessation setting. Participants received between one and four intervention calls aimed at supporting them through their quit attempt. Concurrent with the initiation of this study, three items (confidence, stress, and urges) were added to the standard telephone protocol and assessed at each call. Two principal sets of hypotheses were tested using a combination of ANCOVAs and multiple regression analyses. The first set of hypotheses explored how self-efficacy and changes in self-efficacy within individuals were associated with cessation outcomes. Most research has found a positive linear relation between self-efficacy and quit outcomes, but this study tested the possibility that excessively high self-efficacy may actually reflect an overconfidence bias, and in some cases be negatively related to cessation outcomes. The second set of hypotheses addressed several smoking-related factors expected to affect self-efficacy. As predicted, higher baseline self-efficacy and increases in self-efficacy were associated with higher rates of quitting. However, contrary to predictions, there was no evidence that overconfidence led to diminished cessation success. Finally, as predicted, shorter duration of quit attempts, shorter time to relapse, and stronger urges all were associated with lower self-efficacy. In conclusion, understanding how self-efficacy and changes in self-efficacy affect and are affected by cessation outcomes is useful for informing both future research and current quitline intervention procedures.

Description
Externalizing behaviors are pervasive, widespread, and disruptive across a multitude of settings and developmental contexts. While the conventional diathesis-stress model typically measures the disordered end of the spectrum, studies that span the range of behavior, from externalizing to competence behaviors, are necessary to see the full picture. To that end, this study examined the additive and nonadditive relations of a dimension of parenting (ranging from warm to rejecting), and variants in dopamine, vasopressin, and neuropeptide-y receptor genes on externalizing/competence in a large sample of predominantly Caucasian twin children in toddlerhood, middle childhood, and early adolescence. Variants within each gene were hypothesized to increase biological susceptibility to both negative and positive environments. Consistent with prediction, warmth related to lower externalizing/higher competence at all ages. Earlier levels of externalizing/competence washed out the effect of parental warmth on future externalizing/competence with the exception of father warmth in toddlerhood marginally predicting change in externalizing/competence from toddlerhood to middle childhood. Warmth was a significant moderator of the heritability of behavior in middle childhood and early adolescence such that behavior was less heritable (mother report) and more heritable (father report) in low warmth environments. Interactions with warmth and the dopamine and vasopressin genes in middle childhood and early adolescence emphasize the moderational role gene variants play in relations between the rearing environment and child behavior. For dopamine, the long variant related to increased sensitivity to parent warmth such that the children displayed more externalizing behaviors when exposed to rejection but they also displayed more competence behaviors when exposed to high warmth. Vasopressin moderation was only present under conditions of parental warmth, not rejection. Interactions with neuropeptide-y and warmth were not significant. The picture that emerges is one of gene-environment interplay, wherein the influence of both parenting and child genotype each depend on the level of the other. As genetic research moves forward, gene variants previously implicated as conferring risk for disorder should be reexamined in conjunction with salient aspects of the environment on the full range of the behavioral outcome of interest.

Description
Latinx sexual minority adults experience diverse types of discrimination, including heterosexism and ethnic/racial discrimination, which may contribute to worse physical health. Yet little research has examined how intersectional forms of discrimination, for example, discrimination within another marginalized community contribute to physical health. Greater experiences of discrimination can lead to greater psychological distress which may then exacerbate physical symptoms. It was hypothesized that the association between intersecting forms of discrimination and physical symptom severity would be mediated by psychological distress. Participants (N = 369) identified as Latinx/Hispanic/Latino and as a sexual or gender minority. Data were collected via a self-report web-based survey. Using structural equation modeling, this study tested two theory-informed structure equation models (SEM) proposing pathways between perceived general and within-group discrimination (i.e., Model 1 = racism and racism within LGBTQ+ community; Model 2 = heterosexism and heterosexism within ethnic/racial community), psychological distress (i.e., anxiety and depression), and physical symptom severity. Both structural models demonstrated good fit to the data. As hypothesized, heterosexist discrimination (β = .184, p = .007) and racist discrimination (β = .284, p = .001) significantly predicted higher physical symptom severity in their respective models. Depression symptoms significantly mediated the association between ethnic/racial discrimination and physical symptom severity (β = .189, p = .003). Similarly, greater frequency of heterosexism within one’s ethnic/racial community was indirectly related with worse physical symptoms severity via depression (β = .200, p = .002). No other indirect effects were significant. Findings from this study support that Latinx sexual minority adults may be at risk for discrimination from outside and within their own minority groups which has detrimental effects on health. Noteworthy, depressive symptoms appeared to mediate the effects of heterosexism in one’s ethnic/racial group on physical symptoms. These results highlight how overlapping forms of stigma have differential effects on health via psychological distress. These findings have important clinical and scientific implications in understanding how overlapping forms of discrimination affect health among Latinx sexual minority adults.

Description
Research examining the psychosocial correlates of mental and behavioral health among Latinx populations during the COVID-19 pandemic is limited. This is problematic given that Latinx communities in the U.S. find themselves at the intersection of worse COVID-19-related mortality, mental health distress, and health outcomes. These COVID-19 related disparities came at a time when U.S. Latinxs were already experiencing a disproportionate burden of mental health and substance use disease. Health disparities research has largely focused on Latinxs as a monolithic group, yet in doing so, the intersectionality of race, ethnicity, and socioeconomic status on health are overlooked. It is critical to understand the mental health needs of Latinxs in light of the current COVID-19 pandemic as well as the challenges and potential barriers to services experienced by these communities to better meet their unique needs. Therefore, Study 1 aimed to investigate differences on pandemic-related stressors along economic, emotional, and physical domains, psychological distress, and substance use, based on Latinx ethnicity. The second aim of Study 1 was to identify the most significant pandemic-related stressors and challenges faced by specific Latinx subgroups. Study 2 built off of the results from Study 1. Specifically, Study 2 investigated the association between pandemic-related economic, emotional, and physical stressors examined in Study 1 to various health and mental health outcomes including, psychological distress, alcohol use, and drug use, reported during the pandemic by different Latinx ethnic groups.

Description
Among Latinxs living in the United States (U.S.), AfroLatinx individuals are more susceptible to dying from COVID-19 because of pre-existing health conditions such as diabetes, heart disease, and hypertension (Chapman, 2020). These health disparities, in turn, have been associated with economic inequalities AfroLatinx communities face in the U.S. due to discrimination and racism (Weinstein et al., 2017). Scholars have called attention to the need to focus on AfroLatinx populations, given the systematic denial of AfroLatinx experiences in the psychological literature (Sanchez, 2021) and the systemic and institutional barriers AfroLatinx face when seeking physical and mental health support (Borrell, 2005). Using Borrell's (2005) framework for studying the determinants of health disparities affecting AfroLatinxs, in Study 1, I examined the association between individual characteristics (e.g., socioeconomic indicators), psychosocial factors (e.g., economic distress), and contextual factors (e.g., discrimination) reported by AfroLatinx adults and emotional and physical health problems during the COVID-19 pandemic. As an expansion of Borrell's model, I also examined whether having a pre-existing condition can help explain mental health distress above and beyond other determinants of health disparity. Study 2 built on the first study by helping identify the specific areas of stress and needs identified by AfroLatinxs during the COVID-19 pandemic. The second aim of Study 2 was to determine the more frequent and effective strategies AfroLatinxs with pre-existing conditions used to cope with COVID-19-related stressors and needs.

Description
Adolescent substance use carries a considerable public health burden, and early initiation into use is especially problematic. Research has shown that sensation seeking traits increase risk for substance use experimentation, but less is known about individual and contextual factors that can potentially protect against this risk. This study utilized a longitudinal sub sample of youth (N=567) from a larger study of familial alcoholism to examine sensation seeking in early adolescence (ages 10-15) and its relations to later substance use experimentation. Hypotheses tested whether individual executive control, parenting consistency, neighborhood disadvantage, and neighborhood ethnic concentration moderated sensation seeking’s effects on substance use experimentation using multilevel zero-inflated Poisson modeling. Across models, higher levels of sensation seeking were predictive of a higher likelihood of having initiated substance use, but sensation seeking was not significantly related to the number of different substance use classes tried. Only neighborhood disadvantage emerged as a significant moderator of the path from sensation seeking to substance use initiation. The strength of sensation seeking effects on substance use initiation increased as neighborhood disadvantage decreased below average levels, with the most advantaged neighborhoods exhibiting the strongest link between sensation seeking and substance use. There was also a trend towards the most disadvantaged neighborhoods exhibiting increased sensation seeking effects on substance use initiation. These results highlight the importance of focusing on relatively more advantaged areas as potentially risky environments for the externalizing pathway to substance use.

Description
Pediatric obesity is a public health concern due to its elevated prevalence rates and its relation to concurrent and long-term physical and psychosocial consequences. Pediatric obesity has been found to be associated with problem behaviors, albeit with inconsistent findings. The mechanism of this relation is unclear. It is possible that they have a shared etiology. Self-regulation and parenting practices are two factors that have been implicated in the development of problem behaviors and are garnering evidence for their relation with pediatric obesity. The goal of the present study was to examine whether self-regulation (SREC), positive behavior support (PBSEC), and coercive limit-setting (CLSEC) in early childhood are shared etiological factors of pediatric obesity and problem behaviors. Using multinomial logistic regression the likelihood of belonging to four outcome groups (Comorbid, Problem behavior only, Overweight only, and Typically developing) at age 10 based on these factors was assessed. Analyses controlled for intervention group assignment, child gender, child African-American or Bi-racial, child Hispanic, cumulative risk, child body size impression at age 2, and parent body size impression at baseline. In the models examining SREC alone, for every 1 standard deviation increase in SREC, there was a reliable reduction in the odds of the child belonging to the comorbid and problem behavior only groups at age 10, compared to the typically developing group (OR = 0.386, 95% CI [0.237, 0.628], OR = 0.281, 95% CI [0.157, 0.503], respectively). This relation was maintained when SREC was in the same model as PBSEC and CLSEC. PBSEC and CLSEC alone did not impact the likelihood of belonging to any of the outcome groups. A significant interaction was found between SREC and CLSEC, such that at high levels of both SREC and CLSEC the odds of a child belonging to the overweight only group at age 10 increased, compared to the typically developing group. Results highlight CLSEC as a parenting practice that may place a highly regulated child at risk for becoming overweight. Overall, the findings suggest that problem behaviors and pediatric obesity do not have a shared etiology.

Description
The purpose of this study was to examine if certain child demographics and risk modifiers of the child (i.e., anxiety sensitivity, depressive symptoms, anxiety control, and social competence) predict program response to a Child Anxiety Indicated Prevention and Early Intervention protocol (Pina, Zerr, Villalta, & Gonzales, 2012). This anxiety protocol focused on cognitive behavioral techniques (e.g., systematic and gradual exposure) that used culturally responsive implementation strategies (Pina, Villalta, & Zerr, 2009). The current study aims to investigate specific predictors of program response to this anxiety protocol. First, it was of interest to determine if child demographics and risk modifiers of the child at baseline would predict program response to the early anxiety intervention protocol. Second, it was of interest to see if an interaction with one of the four risk modifiers at baseline and sex or protocol condition would predict program response to the early anxiety intervention protocol. This study included 88 youth (59.14% Hispanic/Latino and 40.9% Caucasian) who were recruited through referrals from public schools and randomized to one of two protocol conditions (i.e., child-only or the child-plus-parent protocol), which had varying levels of mothers’ participation within the Child Anxiety Indicated Prevention and Early Intervention protocol (Pina et al., 2012). Participants ranged from 6 to 17 years of age (M = 10.36, SD = 2.73), and 48.9% were boys. The four risk modifiers were assessed using the Childhood Anxiety Sensitivity Index (CASI; Silverman, Fleisig, Rabian, & Peterson, 1991), Children's Depression Inventory (CDI; Kovacs, 1981), Anxiety Control Questionnaire for Children-Short Form (ACQ-C-S; Weems, 2005), and Social Competence scale from the Child Behavior Checklist (CBCL; Achenbach & Resorla, 2001). Program response was measured by pre-to-posttest changes in anxiety outcomes. Regarding the first aim, each of the four risk modifiers was related to pre-to-posttest changes in program response outcomes. Regarding the second aim for interactions between each of the four focal predictors, sex and protocol condition emerged as moderators. These results have potential implications for clinicians and researchers interested in understanding why some children might experience more or less change when participating in an early intervention protocol for anxiety.

Description
Over 25% of children in the United States suffer from a chronic illness, and close to 70% of all childhood deaths are due to chronic illness. Prevalence of childhood chronic illness continues to increase, and as a result, the pervasiveness of parents faced with stress associated with caregiving for their child with a chronic illness is also rising. The Stress Process Model (SPM) conceptualizes the caregiving experience as a multidimensional process influenced by the caregiving context, primary and secondary stressors, resources, and caregiver outcomes. Utilizing the SPM, the goals of this study were to examine the relations between caregiving stress (role overload and role strain) and resources (instrumental support, social support, and positive attitudes) and psychological outcomes (depression and anxiety) to determine whether resources moderated the associations between caregiving stress and psychological outcomes.
Participants included 200 parent caregivers of a child with a chronic illness. Participants responded to an online survey that measured demographics, role overload (Role Overload scale), role strain (The Revised Caregiver Burden Measure), instrumental support and social support (Medical Outcomes Survey), positive attitudes about caregiving (Brief Assessment Scale for Caregivers), depression (Patient Health Questionnaire-9), and anxiety (Generalized Anxiety Disorder scale-7). Pearson correlations and six hierarchical regression models were tested to examine caregiving stress, resources, and psychological outcomes.
Consistent with the study hypotheses, positive correlations between caregiving stress (role overload and role strain) and depression and anxiety were found. Negative correlations were found between resources (instrumental support, social support, positive attitudes) and depression and anxiety. Both instrumental support and social support had negative moderating effects on the relations between role overload and psychological outcomes (depression and anxiety). Positive attitudes also negatively moderated the relations between role strain and psychological outcomes. Thus, when participants reported high instrumental and social support, they also reported low depression and anxiety, even when role overload was high. Participants also reported low anxiety and depression when they reported high positive attitudes, even when role strain was high. Implications of these findings are discussed.
