RESUMO

BACKGROUND: Preschool psychiatric symptoms significantly increase the risk for long-term negative outcomes. Transdiagnostic hierarchical approaches that capture general ('p') and specific psychopathology dimensions are promising for understanding risk and predicting outcomes, but their predictive utility in young children is not well established. We delineated a hierarchical structure of preschool psychopathology dimensions and tested their ability to predict psychiatric disorders and functional impairment in preadolescence. METHODS: Data for 1253 preschool children (mean age = 4.17, s.d. = 0.81) were drawn from three longitudinal studies using a similar methodology (one community sample, two psychopathology-enriched samples) and followed up into preadolescence, yielding a large and diverse sample. Exploratory factor models derived a hierarchical structure of general and specific factors using symptoms from the Preschool Age Psychiatric Assessment interview. Longitudinal analyses examined the prospective associations of preschool p and specific factors with preadolescent psychiatric disorders and functional impairment. RESULTS: A hierarchical dimensional structure with a p factor at the top and up to six specific factors (distress, fear, separation anxiety, social anxiety, inattention-hyperactivity, oppositionality) emerged at preschool age. The p factor predicted all preadolescent disorders (ΔR2 = 0.04-0.15) and functional impairment (ΔR2 = 0.01-0.07) to a significantly greater extent than preschool psychiatric diagnoses and functioning. Specific dimensions provided additional predictive power for the majority of preadolescent outcomes (disorders: ΔR2 = 0.06-0.15; functional impairment: ΔR2 = 0.05-0.12). CONCLUSIONS: Both general and specific dimensions of preschool psychopathology are useful for predicting clinical and functional outcomes almost a decade later. These findings highlight the value of transdiagnostic dimensions for predicting prognosis and as potential targets for early intervention and prevention.

RESUMO

OBJECTIVE: Lower neural response to reward predicts subsequent depression during adolescence. Both pubertal development and biological sex have important effects on reward system development and depression during this period. However, relations among these variables across the transition from childhood to adolescence are not well characterized. METHOD: Depressive symptoms, pubertal status, and the reward positivity (RewP) event-related potential component, a neural indicator of reward responsivity, were assessed in 609 community-recruited youth at 9, 12, and 15 years of age. Structural equation modeling was used to examine concurrent and prospective relations within and between depression and reward responsiveness as well as the influence of pubertal status and biological sex on these variables across assessments. RESULTS: Stability paths for depression, the RewP, and pubertal status were significant across assessments. Compared with male participants, female participants reported more advanced pubertal status at all assessments, a smaller RewP at age 9, and higher levels of depression at age 15. More advanced pubertal status was associated with a larger RewP at age 15. Most importantly, there were bidirectional prospective effects between the RewP and depression from ages 12 to 15; a lower RewP at age 12 predicted increases in depression at age 15, whereas increased depression at age 12 predicted a lower RewP at age 15. CONCLUSION: These findings indicate that there are bidirectional prospective effects between reward responsiveness and depression that emerge between ages 12 and 15. This may be a crucial time for studying bidirectional reward responsiveness-depression associations across time.

RESUMO

In this article, we consider an often overlooked model that combines mediation and moderation to explain how a third variable can relate to a risk factor-psychopathology relationship. We refer to it as moderation and mediation in a three-variable system. We describe how this model is relevant to studying vulnerability factors and how it may advance developmental psychopathology research. To illustrate the value of this approach, we provide several examples where this model may be applicable, such as the relationships among parental externalizing pathology, harsh parenting, and offspring psychopathology as well as between neuroticism, stressful life events, and depression. We discuss possible reasons why this model has not gained traction and attempt to clarify and dispel those concerns. We provide guidance and recommendations for when to consider this model for a given data set and point toward existing resources for testing this model that have been developed by statisticians and other methodologists. Lastly, we describe important caveats, limitations, and considerations for making this approach most useful for developmental research. Overall, our goal in presenting this information to developmental psychopathology researchers is to encourage testing moderation and mediation in a three-variable system with the aim of advancing analytic strategies for studying vulnerability factors.

RESUMO

Irritability encompasses both normative misbehavior in early childhood and clinically significant problems across development. Recent studies have distinguished between tonic (i.e., persistently angry or grumpy mood) and phasic (i.e., temper tantrums or outbursts) forms of irritability and shown that they have different implications for psychopathology and functioning. However, data on this distinction in young (i.e., preschool aged) children are nonexistent. We utilized data from a longitudinal study of a community sample of 462 3-year-olds followed to age 15. We conducted confirmatory factor analysis (CFA) using items from a diagnostic interview and several parent-report inventories and examined concurrent and prospective associations with clinically relevant variables. The CFA identified dimensions consistent with tonic and phasic irritability. Tonic irritability was independently associated with concurrent parent-reported temperamental negative affectivity and surgency, and depressive and oppositional defiant (ODD) disorders, and predicted higher rates of disruptive behavior disorders (DBD) and suicidal behavior in later childhood and adolescence. Phasic irritability was independently associated with concurrent laboratory observations of child impulsivity, parent-reported temperamental negative affectivity, surgency, and low effortful control, maladaptive parenting, and generalized anxiety disorder (GAD), attention-deficit hyperactivity disorder (ADHD), and ODD, but it did not predict later psychopathology. Tonic and phasic irritability are separable in 3-year-old children, but their correlates and outcomes are not as distinct as in older youth. This may reflect the greater difficulty characterizing normative and pathological irritability in the preschool period.

RESUMO

Tests of statistical interactions (or tests of moderation effects) in personality disorder research are a common way for researchers to examine nuanced hypotheses relevant to personality pathology. However, the nature of statistical interactions makes them difficult to reliably detect in many research scenarios. The present study used a flexible, simulation-based approach to estimate statistical power to detect trait-by-trait interactions common to psychopathy research using the Triarchic model of Psychopathy and the Psychopathic Personality Inventory. Our results show that even above-average sample sizes in these literatures (e.g., N = 428) provide inadequate power to reliably detect trait-by-trait interactions, and the sample sizes needed to detect interaction effect sizes in realistic scenarios are extremely large, ranging from 1,300 to 5,200. The implications for trait-by-trait interactions in psychopathy are discussed, as well as how the present findings might generalize to other areas of personality disorder research. We provide recommendations for how to design research studies that can provide informative tests of interactions in personality disorder research, but also highlight that a more realistic option is to abandon the traditional approach when testing for interaction effects and adopt alternative approaches that may be more productive.

RESUMO

OBJECTIVE: Irritability is a common and clinically important problem in children and adolescents and a risk factor for later psychopathology and impairment. Irritability can manifest in both tonic (e.g., irritable, touchy mood) and phasic (e.g., temper outburst) forms, and recent studies of adolescents suggest that they predict different outcomes. However, no studies have examined whether tonic and phasic irritability are empirically distinguishable in 6-year-old children and whether they have distinct correlates and outcomes. METHOD: We utilized data from a longitudinal study of an unselected community sample of four hundred fifty-two 6-year-olds followed at 3-year intervals to age 15. We conducted confirmatory factor analysis (CFA) using relevant items from a diagnostic interview and several parent-report inventories. RESULTS: The CFA identified dimensions that were consistent with tonic and phasic irritability. Tonic irritability was independently associated with concurrent parent-reported temperamental negative affectivity and internalizing and externalizing disorders at age 6 and predicted higher rates of internalizing psychopathology, and suicidal ideation, in adolescence. Phasic irritability was independently associated with concurrent parent-reported temperamental negative affectivity, surgency, and low effortful control, maladaptive parenting styles and practices, and externalizing disorders at age 6, and predicted higher rates of externalizing psychopathology in adolescence. CONCLUSIONS: Tonic and phasic irritability in 6-year-old children appear to be distinguishable constructs with different temperament and parenting correlates and psychopathological outcomes. Distinguishing these components has implications for research on the etiology and pathophysiology of irritability and developing effective treatments.

RESUMO

The current study examined changes in the agreement, stability, and concurrent and predictive validity of parent- and self-reports on a frequently used measure of youth anxiety symptoms, the Screen for Child Anxiety Related Emotional Disorders (SCARED), from age 9 to 15. A community sample of 531 families (youth, mothers, and fathers) completed the SCARED and a semi-structured diagnostic interview when children were ages 9, 12, and 15. Agreement between youth and each parent on youth anxiety symptoms was weak at age 9 (r = 0.12-0.17), but moderate at age 12 (r = 0.31-0.36) and 15 (r = 0.31-0.46); mother-father (r = 0.50-0.53) agreement was greater than youth-parent agreement at every wave. Stability of youth-reported symptoms was low between age 9 and 12 (r = 0.25), but much higher from age 12 to 15 (r = 0.57); mother- and father-reported youth anxiety symptoms demonstrated high stability (r = 0.53-0.74) at both intervals. Self- and parent-reported youth symptoms were both significantly associated with youth anxiety disorder status, cross-sectionally and prospectively. When considered simultaneously at age 9, only parent-reported anxiety symptoms uniquely predicted concurrent and subsequent youth anxiety diagnoses. However, by age 12, parent- and youth-reported anxiety symptoms were each independently associated with concurrent and subsequent anxiety diagnoses. Agreement, stability, and concurrent and predictive validity of youth self-reported anxiety symptoms are poorer than parent-reports in middle childhood, but comparable by middle adolescence. However, all reporters provide unique information about youth anxiety at each of the developmental periods examined.

RESUMO

Although concurrent associations between parent and child posttraumatic stress symptoms (PTSS) have been well-documented, few longitudinal studies have examined bidirectional influences by modeling the effects of both parent and child PTSS simultaneously over time. The current study examines patterns of PTSS in children and their mothers beginning in preschool and continuing through elementary school age (ages 4-9 years) in a large, heterogeneous sample (N = 331 mother-child dyads). Mothers reported on their own and their child's posttraumatic stress symptoms. A random intercept cross-lagged panel model (RI-CLPM) was used to examine associations between symptoms across six time points. Results indicated that maternal and child symptoms were associated with each other at concurrent time points and tended to fluctuate in a synchronized manner relative to their overall mean symptom levels. Longitudinal cross-lagged paths were significant from mother to child, but non-significant from child to mother, suggesting that mothers' symptom fluctuation at one time point predicted significant fluctuation in children's symptoms at the subsequent time point. The concurrent co-variation of maternal and child symptoms and the predictive nature of maternal symptom flare-ups have important implications for both maternal and child mental health interventions and underscore the importance of attending to mothers' symptomatology early in treatment.

RESUMO

Few investigations have directly compared personality and internalizing symptoms stability within the same sample and have not included personality facets. This study examined rank-order stability and mean-level change of Big Five domains, facets of neuroticism and extraversion, and internalizing symptoms in a sample of 550 adolescent females. Personality and symptoms were assessed every nine months for three years. Three year rank-order stability was higher for personality domains and facets compared to symptoms. Notable exceptions included lower stability of depressivity and positive emotionality facets. Facets and symptoms showed similar mean level change. Overall, we observed modest and variable temporal differences between symptoms and traits; symptoms exhibited high rank-order stability and low mean-level change, but domains and facets were generally more stable.

RESUMO

OBJECTIVE: The long-term clinical and functional outcomes of preschool-age irritability are unknown. This study examined longitudinal associations of preschool irritability with psychiatric disorders and functional impairment assessed in adolescence in a large community sample. METHOD: A total of 453 children were assessed at age 3 and again at ages 12 and/or 15. At age 3, parents were interviewed about their child's irritability, other psychiatric symptoms, and functional impairment with the Preschool Age Psychiatric Assessment (PAPA). In adolescence, both parents and youths were interviewed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime (K-SADS-PL) to assess youth psychopathology and functional impairment; youths also completed the UCLA Life Stress Interview (LSI) to assess different domains of functioning. Lastly, youths and parents completed the Children's Depression Inventory 2 (CDI 2) and the Screen for Child Anxiety Related Disorders (SCARED). RESULTS: Irritability at age 3 predicted internalizing and externalizing disorders in adolescence; parent-reported anxiety and depressive symptoms; and greater functional impairment, including poorer peer functioning, poorer physical health, and antidepressant and educational service use, even after controlling for baseline psychiatric disorders. All longitudinal associations persisted after further adjusting for well-established early life risk markers for psychopathology. CONCLUSION: The findings of this study underscore the clinical significance and predictive power of preschool irritability and provide support for its use in large-scale identification and intervention efforts.

RESUMO

The COVID-19 pandemic has had a profound impact on the lives of individuals, families, and communities around the world with constraints on multiple aspects of daily life. The purpose of the present study was to identify specific profiles of pandemic-related experiences and their relation to psychosocial functioning using the 92-item Epidemic-Pandemic Impacts Inventory (EPII). Data were collected as part of a cross-sectional, online survey of adults (18+) residing in the Northeast region of the United States (N = 652) and recruited via online advertisements. Person-centered latent class analysis (LCA) was applied to 38 pandemic-related experiences that showed a significant bivariate correlation with perceived stress. Measures of psychosocial risk were also obtained. Results revealed five unique profiles of respondents based on patterns of pandemic-related experiences. Three profiles representing about 64% of the sample were characterized by moderate to high exposure to adverse experiences during the pandemic and were more likely to screen positive for depression, anxiety, and posttraumatic stress. These profiles were differentiated by sociodemographic differences, including age, caregiving, and employment status. Two profiles differentiated by age and caregiver status represented about 36% of the sample and were characterized by relatively low exposure to adverse experiences and lower risk for psychosocial impairment. Findings support the EPII as an instrument for measuring tangible and meaningful experiences in the context of an unprecedented pandemic disaster. This research may serve to identify high-risk subpopulations toward developing public health strategies for supporting families and communities in the context of public health emergencies such as the COVID-19 pandemic.

RESUMO

Studies linking child maltreatment to abnormal neurophysiological responses to emotional stimuli and mental health impairment have not specifically explored these patterns in young children exposed to intimate partner violence (IPV). The present study examined two neurophysiological indicators, resting-state electroencephalography and an emotion event-related potential (ERP) in 21 IPV exposed and 30 nonexposed children ages 4-6 years recruited from the community and domestic violence shelters. Frontal alpha asymmetry (FAA) was assessed while at rest. FAA is often associated with avoidant/withdrawn behavior and increased risk of IPV-related mental health conditions (e.g., depression). Additionally, the late positive potential (LPP) ERP component, reflecting motivated attention, was acquired in the context of an age-appropriate affective oddball paradigm with low probability animal pictures as targets and human facial expressions (angry, happy, neutral) as distracters. Results demonstrated that IPV-exposed children, compared with nonexposed children, exhibited lower left FAA during resting state and reduced LPPs to oddball targets and affective faces relative to neutral faces in the oddball task. Together, these results suggest neural patterns associated with a blunted response to emotional stimuli and withdrawal tendencies, respectively, in young children exposed to IPV. Implications for emotional socialization in this vulnerable population are discussed.

RESUMO

PURPOSE: Maternal adverse childhood experiences (ACEs) and intimate partner violence (IPV) are temporally distinct risk factors that negatively impact mothers and their offspring. Risk associated with ACEs and IPV begin during pregnancy, a period of increased physical and psychological demands. The current study examined a person-centered method to empirically identify profiles of pregnant women based on type and severity of ACEs and past-year IPV. Profiles were then differentiated on psychosocial functioning indicators. METHODS: A primarily Latinx, low socioeconomic sample of women (n = 225) completed measures assessing ACEs and past-year IPV, perceived and experienced stress, emotion regulation, and trauma-related symptoms during their third trimester. Latent profile analysis (LPA) was used to identify unique profiles of women based on seven dimensional indicators reflecting threat- and deprivation-based ACEs and IPV. RESULTS: A 4-class solution best fit the data: (1) low probability of ACEs or IPV (64.9%), (2) childhood neglect-only (20.4%), (3) childhood abuse/neglect (10.2%), and (4) polytrauma characterized by a combination of childhood abuse, neglect, and IPV (4.4%). Women with the "childhood abuse/neglect" or "polytrauma" profiles reported more stress and symptoms than women with the "low exposure" profile. Women in the "childhood neglect-only" profile were generally similar to women in the "low exposure" profile, but did report greater difficulties in emotion regulation. CONCLUSIONS: These results suggest that childhood abuse and IPV, exposure types involving threat, are potent correlates of stress, emotion regulation, and mental health difficulties during pregnancy. However, exposure characterized by deprivation alone generally did not increase difficulties.

RESUMO

OBJECTIVES: Emotion dysregulation during pregnancy may impede women's capacity to navigate increased stressors during this period and may elevate risk for psychosocial impairment, especially for socioeconomically disadvantaged or racially marginalized women. Valid and efficient assessment of emotion dysregulation is needed. METHODS: We used Item Response Theory (IRT) to examine the Difficulties in Emotion Regulation Scale (DERS) in 248 low income, primarily Latina/x pregnant women, to compare the short forms relative to the full DERS. RESULTS: IRT indicated that the short forms exhibited modest reliability, but also indicated a substantial decrease in information (i.e., reliability) for the short forms compared with the full DERS. IRT indicated that the DERS-16 appeared more reliable (conserve more information) relative to the other short forms, the DERS-SF and DERS-18. CONCLUSION: Findings suggest that clinicians and researchers use the full DERS when time permits and the DERS-16 when needing a briefer version.

RESUMO

BACKGROUND: Depression is thought to generate stressful life events. However, other internalizing symptoms such as anxiety or post-traumatic stress and individual difference variables such as personality traits and alcohol use may contribute to stressful life events. Whether stress generation is specific to depression or generalized to these other variables is unclear. Therefore, we tested whether stress generation was depression specific or generalizable to anxiety, PTSD, alcohol use, neuroticism, and extraversion. DESIGN: Two-wave longitudinal study with a five-year follow-up. METHODS: 917 young adults completed measures of internalizing symptoms, alcohol use, neuroticism, and extraversion during college and five years later along with an interview-based measure of life events. RESULTS: Symptoms of depression, anxiety, PTSD, and neuroticism exhibited bivariate predictive effects on interpersonal-dependent events. When considering internalizing symptoms in the aggregate, stress generation was specific to symptoms rather than neuroticism. Furthermore, interpersonal-dependent life events mediated Time 1 internalizing symptoms predicting Time 2 symptoms. CONCLUSION: Our results indicate that stress generation applies to internalizing symptoms broadly rather than specifically to depression. Moreover, neuroticism was no longer a significant predictor of life events when examined with internalizing symptoms simultaneously. These results support the value of integrative models that test numerous factors predicting stressful life events.

RESUMO

[Correction Notice: An Erratum for this article was reported online in Psychological Methods on Sep 24 2020 (see record 2020-72092-001). In the article "Do Simple Slopes Follow-Up Tests Lead Us Astray? Advancements in the Visualization and Reporting of Interactions," by Megan C. Finsaas and Brandon L. Goldstein (Psychological Methods, advance online publication. April 20, 2020. http://dx.doi.org/10.1037/ met0000266), Figure 5 contained an error. The second sentence of the caption of Figure 5 should read: "The left plot depicts the region of significance when life stress is acting as the moderator, and the right when neuroticism is acting as the moderator." All versions of this article have been corrected.] Statistical interactions between two continuous variables in linear regression are common in psychological science. As a follow-up analysis of how the moderator impacts the predictor-outcome relationship, researchers often use the pick-a-point simple slopes method. The simple slopes method requires researchers to make two decisions: (a) which moderator values should be used for plotting and testing simple slopes, and (b) which predictor should be considered the moderator. These decisions are meant to be driven by theory, but in practice researchers may use arbitrary conventions or theoretical reasons may not exist. Even when done thoughtfully, simple slopes analysis omits important information about the interaction. Consequently, it is problematic that the simple slopes approach is the primary basis for interpreting interactions. A more nuanced alternative is to utilize the Johnson-Neyman technique in conjunction with a regression plane depicting the interaction effect in three-dimensional space. This approach does not involve picking points but rather shows the slopes at all possible values of the predictor variables and gives both predictors equal weight instead of selecting a de facto moderator. Because this approach is complex and user-friendly implementation tools are lacking, we present a tutorial explaining the Johnson-Neyman technique and how to visualize interactions in 3-D space along with a new open-source tool that completes these procedures. We discuss how this approach facilitates interpretation and communication as well as its implications for replication efforts, transparency, and clinical applications.

RESUMO

BACKGROUND: Early irritability predicts a broad spectrum of psychopathology spanning both internalizing and externalizing disorders, rather than any particular disorder or group of disorders (i.e. multifinality). Very few studies, however, have examined the developmental mechanisms by which it leads to such phenotypically diverse outcomes. We examined whether variation in the diurnal pattern of cortisol moderates developmental pathways between preschool irritability and the subsequent emergence of internalizing and externalizing symptoms 9 years later. METHOD: When children were 3 years old, mothers were interviewed about children's irritability and completed questionnaires about their children's psychopathology. Six years later, children collected saliva samples at wake-up and bedtime on three consecutive days. Diurnal cortisol patterns were modeled as latent difference scores between evening and morning samples. When children were approximately 12 years old, mothers again completed questionnaires about their children's psychopathology. RESULTS: Among children with higher levels of irritability at age 3, a steeper diurnal cortisol slope at age 9 predicted greater internalizing symptoms and irritability at age 12, whereas a blunted slope at age 9 predicted greater externalizing symptoms at age 12, adjusting for baseline and concurrent symptoms. CONCLUSION: Our results suggest that variation in stress system functioning can predict and differentiate developmental trajectories of early irritability that are relatively more internalizing v. those in which externalizing symptoms dominate in pre-adolescence.

RESUMO

Social anhedonia is well established as a transdiagnostic factor, but little is known about its development. This study examined whether temperament and parenting in early childhood predict social anhedonia in early adolescence. We also explored whether the relationships between early predictors and social anhedonia are moderated by a child's sex. A community sample of children participated in laboratory observations of temperament and parenting practices at age 3 (n = 275). The participants returned at age 12 and completed the Anticipatory and Consummatory Interpersonal Pleasure Scale-Child Version (ACIPS-C). Our results indicated that, at age 3, lower observed sociability predicted higher levels of social anhedonia at age 12. These associations were moderated by child sex, such that males with diminished sociability reported greater social anhedonia. These findings indicate that predictors of early adolescent social anhedonia are evident as early as 3 years of age. However, these effects were evident only for males, suggesting that the pathways to social anhedonia in early adolescence differ as a function of sex.

RESUMO

Purpose: Childhood exposure to traumatic violence may shape how children respond to threatening faces and increase risk for psychopathology. Maltreated children may exhibit altered processing of threatening faces; however, the effects of witnessing intimate partner violence (IPV) on children's discrimination of facial expressions is under-studied. Emotional face processing differentially relates to psychopathology, with some evidence suggesting improved detection of angry faces in children with fear-related anxiety symptoms, whereas externalizing symptoms are associated with poorer detection of fearful faces and perhaps emotional faces broadly. Method: In this cross-sectional study, we examined discrimination of threatening emotional faces (angry, fearful) in relation to experiences of probable abuse and witnessing of physical IPV, as well as psychopathology. Children (N = 137, mean age = 5.01 years, SD = 0.81) completed a "face in the crowd task" designed to examine discrimination of angry and fearful faces. Children either searched for an angry face among fearful distractor faces or a fearful face among angry distractors. Probable child abuse, witnessed IPV, and symptoms were assessed in semi-structured maternal interviews. Results: Children who witnessed violence showed poorer accuracy when fearful faces were the target; however, effects for probable abuse were non-significant. Greater fear-related anxiety symptoms were associated with poorer accuracy for fearful faces. Externalizing symptoms were associated with poorer overall accuracy. Conclusions: Findings suggest that IPV and fear-related anxiety symptoms were associated with difficulty detecting fearful faces when angry distractors were present, consistent with prior research. Implications of violence- and symptom-associated deficits in emotional face processing are discussed.

RESUMO

BACKGROUND: Reward processing deficits have been implicated in the etiology of depression. A blunted reward positivity (RewP), an event-related potential elicited by feedback to monetary gain relative to loss, predicts new onsets and increases in depression symptoms. Etiological models of depression also highlight stressful life events. However, no studies have examined whether stressful life events moderate the effect of the RewP on subsequent depression symptoms. We examined this question during the key developmental transition from childhood to adolescence. METHODS: A community sample of 369 children (mean age of 9) completed a self-report measure of depression symptoms. The RewP to winning v. losing was elicited using a monetary reward task. Three years later, we assessed stressful life events occurring in the year prior to the follow-up. Youth depressive symptoms were rated by the children and their parents at baseline and follow-up. RESULTS: Stressful life events moderated the effect of the RewP on depression symptoms at follow-up such that a blunted RewP predicted higher depression symptoms in individuals with higher levels of stressful life events. This effect was also evident when events that were independent of the youth's behavior were examined separately. CONCLUSIONS: These results suggest that the RewP reflects a vulnerability for depression that is activated by stress.
