CBCL Behavior Problems of Post-Institutionalized International Adoptees

With the increase in international adoptions during the last decade, many researchers have investigated the developmental outcomes of these adoptees, including their extreme behaviors. Collectively, these results have not always appeared consistent across studies, perhaps because studies have used children reared in institutions or not, the institutional environments vary in severity, children spend different lengths of time in the institution and are assessed at different ages, and studies use different outcome measures. In an attempt to discern more order in the literature, this review focuses on 18 studies, each of which used the Child Behavior Checklist, and their outcomes are viewed with respect to these parameters. Results suggest that the major factor contributing to extreme behaviors is age at adoption, with those adopted after 6/18 months having more behavior problems, especially Internalizing, Externalizing, and Attention problems. Generally, samples of post-institutional children have more problems than samples of mixed or non-institutional internationally adopted children, and some problems are more likely to be manifest in adolescence, suggesting the effects of deficient early experiences are not simply the persistence of learned behavior but more general dispositions that become more noticeable or severe during adolescence. Findings are discussed in terms of early deficient social–emotional caregiver–child interactions that characterize most institutional environments as a possible major cause of later difficulties in post-institutionalized children.     

The Relationship Between Childhood Onset Obesity and Psychopathology in Adulthood

We administered the Symptom Checklist (Derogatis, 1975; SCL-90-R) to 37 obese subjects in outpatient treatment for obesity. Patients with early onset obesity demonstrated a greater frequency and higher levels of emotional distress and psychiatric symptomatology than patients with late onset obesity. Individuals who developed obesity in childhood showed more psychopathology than those who developed obesity later in life. Overall, these findings support the belief that obesity is characteristically associated with greater internal psychological conflict. These findings further suggest that childhood obesity could serve as a predictor variable for possible future psychological disturbance in obese populations.     

Reclaiming Culture: Reculturation of Transracial and International Adoptees

The cultural experiences of transracial and international adoptees (TRIAs) are uniquely affected by their adoption across cultures and racial/ethnic groups. Upon adoption, TRIAs typically identify quickly with their adoptive parents’ White culture but may eventually seek to reclaim their birth culture. Current terminology used to describe cultural identifications and changes (e.g., acculturation, enculturation) does not adequately depict the reclamation of birth culture by TRIAs. The authors describe a new term for this process called reculturation.     

Parental Psychopathology and Paternal Child Neglect in Late Childhood

We aimed at determining the association of both severity of paternal and maternal substance use disorder (SUD) and psychiatric disorders with paternal child neglect severity during late childhood. The sample comprised 146 intact SUD (n=71) and non SUD (n=75) families with a 10–12 year old female or male biological offspring. The average age of fathers, mothers, and children was 44 (SD=5.9), 42 (SD=4.78), and 11 (SD=.79) years, respectively. The ethnic composition was 85% Caucasian and 15% African American. The results showed that paternal and maternal SUD and psychiatric disorders severity was correlated with paternal child neglect severity. However, paternal psychopathology failed to achieve significance in the regression analyses. Severity of maternal, especially severity of antisocial personality disorder symptoms was associated with paternal child neglect. These results are discussed within the framework of evolutionary psychology research examining paternal investment in the offspring. Implications for the necessity of identifying parental psychopathology and an integrated treatment approach are discussed.     

The Structure of Psychopathology in a Community Sample of Preschoolers

Despite growing interest in the development of alternative diagnostic classification systems for psychopathology in young children, little is known about the adequacy of the DSM symptom structure for describing psychopathology in this population. This paper examines the fit of the DSM-IV emotional (ED) and disruptive behavior disorder (DD) symptom structure in a community sample of 796 4-year-old children. Using the parent-report Child Symptom Inventory (CSI), the best model fit for ED included separate factors for Social Phobia, Separation Anxiety Disorder, Generalized Anxiety Disorder, and Major Depressive Disorder. For DD, the best model included separate Attention Deficit Hyperactivity Disorder-Inattentive type (ADHD-I), Attention Deficit Hyperactivity Disorder-Hyperactive/Impulsive type (ADHD-HI), and Oppositional Defiant Disorder diagnoses. These findings support using DSM-IV nosology to classify EDs in a community sample of preschool children, and suggest differentiation of ADHD into ADHD-I and ADHD-HI.

Childhood Irritability: Predictive Validity and Mediators of Adolescent Psychopathology

Despite its transdiagnostic significance, there is modest evidence with respect to the predictive validity of childhood irritability, especially across developmental periods; similarly, little is known about explanatory factors underlying these predictions. This study had two goals: (1) to test the predictive validity of childhood irritability with respect to adolescent internalizing and externalizing problems, controlling for baseline ADHD and related psychopathology and (2) to test theoretically-derived family (i.e., parenting behavior, parenting stress) and social (i.e., peer status, social skills) constructs as explanatory factors of adolescent psychopathology. Two hundred thirty ethnically diverse (51.5% White) 5–10-year-old youth (32% female) with (n?=?121) and without (n?=?110) ADHD completed three separate laboratory-based assessments across six to seven years. Temporally-ordered predictors, putative mediators, and psychopathology outcomes were assessed using multiple informants (i.e., parent, teacher, youth) and methods (i.e., structured interviews, normed rating scales). Controlling for demographic factors, clinical correlates, and baseline psychopathology, childhood irritability uniquely predicted adolescent externalizing problems, but not internalizing problems. Next, analyses revealed that low social skills partially explained predictions of adolescent internalizing problems. However, family or social factors did not underlie predictions of adolescent externalizing problems. These preliminary findings support the predictive validity of childhood irritability with respect to early adolescent externalizing problems and implicate low social skills as a potentially unique mediator of internalizing outcomes. Intervention-induced improvements in social skills may minimize emergent psychopathology initiated by significant childhood irritability.

     

Early Childhood Adversities and Trajectories of Psychiatric Problems in Adoptees: Evidence for Long Lasting Effects

The aim of the present study is to investigate whether early childhood adversities determine the longitudinal course of psychiatric problems from childhood to adulthood; in particular if the impact of early maltreatment on psychopathology decreases as time passes. A sample of 1,984 international adoptees was followed (955 males and 1029 females; adopted at the mean age of 29 months). Parents provided information about abuse, neglect and number of placements prior to adoption at baseline and completed the Child Behavior Checklist or the Young Adult Behavior Checklist three times when their children were between 10 and 30 years of age. Multilevel analyses were performed to determine trajectories of psychiatric problems. Experience of early childhood adversity prior to adoption substantially increased the level of psychiatric problems, especially when maltreatment was severe. Moreover, the impact of early adversities on psychiatric problems remained markedly stable. This suggests that vulnerability of early-maltreated children persists even if they are taken out of their problematic environments and are raised in enriched circumstances.     

Unique Associations between Childhood Temperament Characteristics and Subsequent Psychopathology Symptom Trajectories from Childhood to Early Adolescence

Existing research suggests that temperamental traits that emerge early in childhood may have utility for early detection and intervention for common mental disorders. The present study examined the unique relationships between the temperament characteristics of reactivity, approach-sociability, and persistence in early childhood and subsequent symptom trajectories of psychopathology (depression, anxiety, conduct disorder, and attention-deficit hyperactivity disorder; ADHD) from childhood to early adolescence. Data were from the first five waves of the older cohort from the Longitudinal Study of Australian Children (n = 4983; 51.2% male), which spanned ages 4–5 to 12–13. Multivariate ordinal and logistic regressions examined whether parent-reported child temperament characteristics at age 4–5 predicted the study child’s subsequent symptom trajectories for each domain of psychopathology (derived using latent class growth analyses), after controlling for other presenting symptoms. Temperament characteristics differentially predicted the symptom trajectories for depression, anxiety, conduct disorder, and ADHD: Higher levels of reactivity uniquely predicted higher symptom trajectories for all 4 domains; higher levels of approach-sociability predicted higher trajectories of conduct disorder and ADHD, but lower trajectories of anxiety; and higher levels of persistence were related to lower trajectories of conduct disorder and ADHD. These findings suggest that temperament is an early identifiable risk factor for the development of psychopathology, and that identification and timely interventions for children with highly reactive temperaments in particular could prevent later mental health problems.     

Reciprocal Relationships Between Parenting Behavior and Disruptive Psychopathology from Childhood Through Adolescence

Theoretical models suggest that child behaviors influence parenting behaviors, and specifically that unpleasant child behaviors coerce parents to discontinue engaging in appropriate discipline. This study examined reciprocal relationships between parenting behaviors (supervision, communication, involvement, timid discipline and harsh punishment) and child disruptive disorder symptoms (ADHD, ODD and CD) in a clinic-referred sample of 177 boys. Annual measures, including structured clinical interviews, were obtained from the beginning of the study (when boys were between the ages of 7 to 12) to age 17. Specific reciprocal influence was observed; only timid discipline predicted worsening behavior, namely ODD symptoms, and ODD symptoms predicted increases in timid discipline. Greater influence from child behaviors to parenting practices was found: ODD also predicted poorer communication and decreased involvement, and CD predicted poorer supervision. ADHD was neither predictive of, nor predicted by, parenting behaviors. The results are specifically supportive of a coercive process between child behaviors and parenting behaviors, and generally suggestive of greater influence of child behaviors on parenting behaviors than of parenting behaviors on child behaviors.     

The Development of Latent Dimensions of Psychopathology across Early Childhood: Stability of Dimensions and Moderators of Change

Recent research has described the structure of psychopathology as including one general and multiple specific factors, and this structure has been found in samples across development. However, little work has examined whether this structure is consistent across time, particularly in young children, within the same sample. Further, few studies have examined factors that influence the magnitude of the stability of latent dimensions of psychopathology. In the present study, we examine these issues in a community sample of 545 children assessed at ages 3 and 6. In addition, we explored child temperament, parental history of psychopathology, and parenting behaviors as potential moderators of the longitudinal stability of latent dimensions of psychopathology. We found that the same bifactor model structure identified at age 3 provided an adequate fit to the data at age 6. Further, our model revealed significant homotypic stability of the general, internalizing, and externalizing specific factors. We also found evidence of differentiation of psychopathology over time with the general factor at age 3 predicting the externalizing factor at age 6. However, we failed to identify moderators of the longitudinal associations between psychopathology latent factors. Overall, our results bolster support for the bifactor structure of psychopathology, particularly in early childhood.     

Clarifying the Placement of Obsessive-Compulsive Disorder in the Empirical Structure of Psychopathology

Recent work on the empirical structure of psychopathology has aimed to address some limitations that can arise from traditional categorical classification approaches. This research has focused on modeling patterns of co-occurrence among traditional diagnoses, uncovering a variety of well-validated dimensions (or spectra) of psychopathology, spanning common and uncommon mental disorders. A model integrating these empirically derived spectra (the Hierarchical Taxonomy of Psychopathology; HiTOP) has been proposed. However, the placement of obsessive-compulsive disorder (OCD) within this model remains unclear, as studies have variably found OCD to fit best as part of the Fear, Distress or Thought Disorder spectra. One reason for this may be the heterogeneity of symptoms experienced by individuals with OCD, which is lost when analysing categorical diagnoses. For example, different symptom clusters within OCD—such as washing and contamination versus obsessions and checking—may be differentially associated with different spectra in the HiTOP model. The aim of this study was to test this hypothesis. Data were collected in an anonymous online survey from community participants (n?=?609), largely with elevated symptoms of mental illness, and analyzed in a factor analytic framework treating OCD as a unitary construct and as four separate symptom clusters. The results indicated that OCD and its constituent symptom clusters had significant loadings of varying strength on the Fear and Thought Disorder spectra. These findings suggest that OCD may be best characterized as cross-loading on both the Fear and Thought Disorder spectra, and highlight the importance of accounting for diagnostic heterogeneity in future research.

     

The Logical Structure of International Trade Theory

In this paper the structuralist approach of theory reconstruction is applied to International Trade Theory. In the basic element the universal laws of the theory are stated and the general concepts are defined in terms of three sets and seven functions. Ricardo’s Theory of Comparative Advantage and the Factor Proportions Theory by Heckscher and Ohlin are reconstructed as specialisations of the basic element. Two intratheoretical constraints are formulated in order to ensure the consistency of the theory. A number of empirical studies are shown to be paradigmatic, successful or questionable applications of International Trade Theory. The reconstruction allows the assessment of the theory from a metatheoretical angle and illuminates the logical interdependencies of its components.

The Developmental Psychopathology of Worry

Although childhood generalized anxiety disorder is generally understudied, worry, the cardinal feature of GAD, appears to be relatively common in youth. Despite its prevalence, there are few conceptual models of the development of clinical worry in children. The current review provides a framework for integrating the developmental psychopathology perspective, models of worry in adults, and data available on worry in children. General risk factors for the development of worry are considered, as well as potential pathways including genetics, temperament, cognitive, emotional and parenting influences, as well as the influence of cognitive development. Based on this review, it appears unlikely that main effects models will be able to explain the development of GAD or clinical worry in children and that a broad, complex model incorporating a number of factors and their interactions will best describe etiological and maintaining factors. With this perspective in mind, a number of suggestions for future work are offered.     

Parenting Stress and Childhood Psychopathology: An Examination of Specificity to Internalizing and Externalizing Symptoms

The purpose of this study was to examine if specificity exists between three factors of parenting stress (i.e., parental distress, parent–child (PC) dysfunctional interactions, and difficult child) and childhood internalizing and externalizing symptoms. The incremental validity of parenting stress beyond parental psychopathology was also examined. The sample was drawn from families of children aged 5–17 (N = 300), who sought treatment for their child from a community mental health clinic. Results indicated that the PC dysfunctional interactions factor showed specificity to internalizing symptoms when controlling for parental psychopathology. Parental distress did not show specificity or incremental validity and the difficult child factor was associated with both internalizing and externalizing symptoms when controlling for parental psychopathology. The influence of age, gender, and ethnicity on these associations is also presented, and findings are discussed in terms of how the results add to understanding the specific relations between parenting stress and child and adolescent symptoms.     

The Structure of Internalizing Disorders in Middle Childhood and Evidence for Personality Correlates

The current multi-method multi-informant investigation compared the fit of three competing models of internalizing problems in middle childhood: (1) a unitary factor model, (2) a two-factor model corresponding to the DSM-IV Anxiety/Depression distinction, and (3) a two-factor model corresponding to the Fear/Distress distinction observed in structural studies of adult psychopathology (Krueger Archives of General Psychiatry, 56:921-926, 1999); Slade and Watson Psychological Medicine, 36:1593-1600, 2006). In total, 346 youths (mean age = 9.51, SD = .78) and their adult caregivers (344 mothers, 227 fathers) reported on childhood internalizing symptoms and personality traits. Confirmatory factor analyses revealed adequate to good fit indices for all three models, although the unitary factor model provided the most parsimonious summary of the data. Although the structural analyses suggested that internalizing symptom subfactors were not clearly differentiated in middle childhood, hierarchical regression analyses revealed that personality dimensions uniquely predicted the Anxiety/Fear and Depression/Distress disorders. These results suggest that personality correlates differentiate childhood psychopathology structure before it is manifest at the symptom level.     

The Roles of Persistence and Perseveration in Psychopathology

Two constructs were hypothesized to be of importance in psychological disorders: persistence (the ability to keep going to reach a goal, even when the task is difficult or drawn out) and perseveration (the tendency to continue a behavior, even when it ceases to be effective or rewarding). These are contrasted with perfectionism (having high standards for oneself or others). A measure was developed to address these constructs (the Persistence, Perseveration and Perfectionism Questionnaire; PPPQ). The PPPQ was administered to 325 nonclinical participants, alongside a measure of psychological disturbance. Factor analysis resulted in a 22-item version of the measure, consisting of subscales with good psychometric properties corresponding to the 3 theoretical constructs. Persistence was associated with lower levels of psychopathology, whereas perseveration was associated with higher levels of psychopathology. Perfectionism was weakly associated with psychopathology. Further work is needed to develop these constructs with clinical groups, but the findings support the hypothesis that persistence is an adaptive construct whereas perseveration is maladaptive.
