Social media as an incubator of personality and behavioral psychopathology: Symptom and disorder authenticity or psychosomatic social contagion?

There has been an increasing recognition among both medical and psychological professionals, as well as the public media, of a concerning trend for child and adolescent users of audiovisual-based, algorithmic social media platforms (e.g., TikTok) to present with or claim functional psychiatric impairment that is inconsistent with or distinct from classic psychiatric nosology. In this short communication, we provide a detailed historical overview of this transdiagnostic phenomenon and suggest a conceptual model to organize thinking and research examining it. We then discuss the implications of our suggested model for accurate assessment, diagnosis, and medical-psychiatric treatment. We believe there is an urgent need for focused empirical research investigation into this concerning phenomenon that is related to the broader research and discourse examining social media influences on mental health.

An integrative evolutionary framework for psychopathology.

The field of psychopathology is in a transformative phase, and is witnessing a renewed surge of interest in theoretical models of mental disorders. While many interesting proposals are competing for attention in the literature, they tend to focus narrowly on the proximate level of analysis and lack a broader understanding of biological function. In this paper, we present an integrative framework for mental disorders built on concepts from life history theory, and describe a taxonomy of mental disorders based on its principles, the fast-slow-defense model (FSD). The FSD integrates psychopathology with normative individual differences in personality and behavior, and allows researchers to draw principled distinctions between broad clusters of disorders, as well as identify functional subtypes within current diagnostic categories. Simulation work demonstrates that the model can explain the large-scale structure of comorbidity, including the apparent emergence of a general "p factor" of psychopathology. A life history approach also provides novel integrative insights into the role of environmental risk/protective factors and the developmental trajectories of various disorders.

Individual- and family-level associations between child psychopathology and parenting.

Parenting can protect against the development of, or increase risk for, child psychopathology; however, it is unclear if parenting is related to psychopathology symptoms in a specific domain, or to broad liability for psychopathology. Parenting differs between and within families, and both overall family-level parenting and the child-specific parenting a child receives may be important in estimating transdiagnostic associations with psychopathology. Data come from a cross-sectional epidemiological sample (N = 10,605 children ages 4-17, 6434 households). Parents rated child internalizing and externalizing symptoms and their parenting toward each child. General and specific (internalizing, externalizing) psychopathology factors, derived with bifactor modeling, were regressed on parenting using multilevel modeling. Less warmth and more aversive/inconsistent parenting in the family, and toward an individual child relative to family average, were associated with higher general psychopathology and specific externalizing problems. Unexpectedly, more warmth in the family, and toward an individual child relative to family average, was associated with higher specific internalizing problems in 4-11 (not 12-17) year-olds. Less warmth and more aversive/inconsistent parenting are broad correlates of child psychopathology. Aversive/inconsistent parenting, is also related to specific externalizing problems. Parents may behave more warmly when their younger children have specific internalizing problems, net of overall psychopathology.

Middle-childhood executive functioning mediates associations between early-childhood autism symptoms and adolescent mental health, academic and functional outcomes in autistic children.

BACKGROUND: Executive functioning (EF) varies in children with autism spectrum disorder (ASD) and is associated with clinical symptoms, academic, and adaptive functioning. Here, we examined whether middle-childhood EF mediates associations between early-childhood autism symptoms and adolescent outcomes in children with ASD. METHODS: The Pathways in ASD Cohort comprising children recruited at the time of ASD diagnosis (at 2-4 years-of-age) and followed prospectively across eight subsequent timepoints over ~10 years was used. A subset of Pathways participants (n = 250) with Behavior Rating Inventory of Executive Function (BRIEF)-Parent Form data from at least one timepoint when participants were school-aged was analyzed. A mediation framework was used to examine whether BRIEF-measured EF across age 7-10 years (middle-childhood) mediated associations between early-childhood autism symptoms (measured using the parent-report Social Responsiveness Scale across age 2-6 years) and clinical, academic, and functional outcomes, indexed at age >10-11.8 years (early-adolescence) using the Child Behavior Checklist (CBCL)-Internalizing and Externalizing Scales, Academic Performance from the Teacher's Report Form, and Vineland Adaptive Behavior Scales. Models were rerun substituting clinician-rated and teacher-rated measures, where possible. RESULTS: Mediation models indicated a significant indirect effect of middle-childhood EF on associations between early-childhood autism symptoms and externalizing behavior, academic performance, or adaptive functioning in early adolescence; kappa squared (κ2 ) effect sizes ranged from large to small. Model findings were stable across raters. Middle-childhood EF did not mediate associations between early-childhood autism symptoms and adolescent internalizing behavior. CONCLUSIONS: Among children with an ASD diagnosis, middle-childhood EF may be one pathway through which early-childhood autism symptoms influence a variety of outcomes in early-adolescence. An experimental study targeting middle-childhood EF to improve adolescent academic, emotional/behavioral, and adaptive functioning is needed to evaluate the clinical meaningfulness of these findings.

Growing points in attachment disorganization: looking back to advance forward.

In this special issue paper we reflect on the next generation of attachment research with a focus on disorganization, a central but still poorly understood topic in this area. We suggest that progress will be facilitated by a return to attachment theory's evolutionary roots, and to the emphasis on biological function that inspired Bowlby's original thinking. Increased interdisciplinary cross-fertilization and collaborations would enable novel and generative research on some of the long-standing questions surrounding attachment disorganization. Accordingly, we present an agenda for future research that encompasses contributions of modern ethology and neurobiology, novel hypotheses based on the concept of adaptive decanalization, connections with neurodevelopmental vulnerability and risk for mental disorders such as schizophrenia, and the possibility of sex differences in the behavioral manifestations of attachment disorganization. We believe that these avenues of theory and research offer exciting potential for innovative work in attachment disorganization in the years ahead.

Feasibility of training service providers on the AMBIANCE-Brief measure for use in community settings.

The Atypical Maternal Behavior Instrument for Assessment and Classification-Brief (AMBIANCE-Brief) was developed to provide a clinically useful and psychometrically sound assessment of disrupted parenting behavior for community practitioners. With prior evidence of this tool's reliability and validity in laboratory settings, this study aimed to determine whether providers from family service agencies could become reliable in the use of the level of disrupted communication following a brief training. Providers (N = 46) from three agency sites participated in a 2-day AMBIANCE-Brief training and, at the end of the training, coded eight videotaped mother-child interactions. Novice participant coding was compared to expert consensus ratings using intraclass correlations. On average, participants' interrater agreement was good (ICCmean  = .84, SD = 0.10), with 89% meeting the reliability standards of ICC ≥ .70. In response to queries, 100% of participants indicated that they would recommend the AMBIANCE-Brief training to their colleagues, 85% reported that the AMBIANCE-Brief measure would be useful or very useful for their clinical practice, and 56% of participant clinicians believed that parents would find the measure acceptable or very acceptable for integration into intervention or support planning. Altogether, these findings speak to the feasibility of using the AMBIANCE-Brief in community settings. Future studies are needed in diverse clinical and community contexts to evaluate whether use of this assessment tool can inform more targeted interventions tailored to the specific needs of families.

El Instrumento Abreviado para Evaluación y Clasificación de la Conducta Materna Atípica (AMBIANCE-Abreviado; Madigan, Bronfman, Haltigan y Lyons-Ruth, 2018) se desarrolló para ofrecer a quienes practican en la comunidad una evaluación clínicamente útil y sicométricamente acertada de la conducta de crianza trastornada. Con la anterior evidencia de la confiabilidad y validez de esta herramienta en el marco de los laboratorios (Cooke, Eirich, Racine, Lyons-Ruth y Madigan, 2020), este estudio se propuso determinar si se podría confiar en quienes proveen el servicio como parte de las agencias de servicio a las familias después de un breve entrenamiento. Los proveedores (N = 46) de tres lugares de agencias participaron en un entrenamiento de dos días sobre AMBAIANCE-Abreviado y, al final del entrenamiento, codificaron ocho interacciones madre-niño grabadas en video. Se comparó la forma de codificar de los novatos con el puntaje consenso de los expertos usando correlaciones dentro de clases. El acuerdo entre los evaluadores fue bueno (ICC media = .84, SD = 0.10), con un 89% de los participantes que lograron el estándar de confiabilidad de ICC > .70. En respuesta a preguntas, el 100% de los participantes indicó que ellos recomendarían el entrenamiento de AMBIANCE-Abreviado a sus colegas, 85% reportó que la medida AMBIANCE-Abreviado sería útil o muy útil en su práctica clínica, y 56% creían que los progenitores encontrarían la medida aceptable o muy aceptable para ser integrada en la intervención o el planeamiento de apoyo. En conjunto, estos resultados hablan de la factibilidad de usar AMBIANCE-Abreviado en el marco comunitario.

L'Instrument d'Evaluation et de Classification-Brève du Comportement Maternel Atypique (AMBIANCE-Bref; Madigan, Bronfman, Haltigan, & Lyons-Ruth, 2018) a été développé afin d'offrir une évaluation du comportement de parentage perturbé, cliniquement utile et saine du point de vue psychométrique, pour les acteurs communautaires. Avec des preuves préalables de la fiabilité et de la validité de cet outil en laboratoire (Cooke, Eirich, Racine, Lyons-Ruth, & Madigan, 2020), cette étude s'est donné pour but de déterminer si les prestataires des agences de service à la famille pouvaient devenir fiables pour son utilisation après une formation courte. Des prestataires (N = 46) de trois sites d'agence ont participé à une formation AMBIANCE-Bref de deux jours et à la fin de la formation ont codé huit interactions mère-enfant filmées. Le codage du participant débutant a été comparé aux évaluations par consensus d'expertes en utilisant des corrélations intraclasses. Le coefficient d'objectivité était bon (moyenne des coefficient de corrélation intraclasse [ICC] = 84, SD = 0,10), avec 89% des participants remplissant les standards de fiabilité d'ICC ICC ³,70. En répondant aux questions, 100% des participants ont indiqué qu'ils ou elles recommanderaient la formation AMBIANCE-bref à leurs collègues, 85% ont indiqué que la mesure AMBIANCE-bref serait utile ou très utile pour leur pratique clinique, et 56% ont déclaré qu'ils ou elles croyaient que les parents trouveraient cette mesure acceptable ou très acceptable pour une intégration à une intervention ou le plan de soutien. Au total, ces résultats parlent de la viabilité de l'utilisation de l'AMBIANCE-bref dans des contextes communautaires.

Les progrès dans la réalisation de la classification quantitative de la psychopathologie.

Shortcomings of approaches to classifying psychopathology based on expert consensus have given rise to contemporary efforts to classify psychopathology quantitatively. In this paper, we review progress in achieving a quantitative and empirical classification of psychopathology. A substantial empirical literature indicates that psychopathology is generally more dimensional than categorical. When the discreteness versus continuity of psychopathology is treated as a research question, as opposed to being decided as a matter of tradition, the evidence clearly supports the hypothesis of continuity. In addition, a related body of literature shows how psychopathology dimensions can be arranged in a hierarchy, ranging from very broad "spectrum level" dimensions, to specific and narrow clusters of symptoms. In this way, a quantitative approach solves the "problem of comorbidity" by explicitly modeling patterns of co-occurrence among signs and symptoms within a detailed and variegated hierarchy of dimensional concepts with direct clinical utility. Indeed, extensive evidence pertaining to the dimensional and hierarchical structure of psychopathology has led to the formation of the Hierarchical Taxonomy of Psychopathology (HiTOP) Consortium. This is a group of 70 investigators working together to study empirical classification of psychopathology. In this paper, we describe the aims and current foci of the HiTOP Consortium. These aims pertain to continued research on the empirical organization of psychopathology; the connection between personality and psychopathology; the utility of empirically based psychopathology constructs in both research and the clinic; and the development of novel and comprehensive models and corresponding assessment instruments for psychopathology constructs derived from an empirical approach.

Toward precision therapeutics: general and specific factors differentiate symptom change in depressed adolescents.

BACKGROUND: The longitudinal course of multiple symptom domains in adolescents treated for major depression is not known. Revealing the temporal course of general and specific psychopathology factors, including potential differences between psychotherapies, may aid therapeutic decision-making. METHODS: Participants were adolescents with major depressive disorder (aged 11-17; 75% female; N = 465) who were part of the IMPACT trial, a randomized controlled trial comparing cognitive behavioral therapy, short-term psychoanalytic psychotherapy, and brief psychosocial intervention. Self-reported symptoms at baseline and 6, 12, 36, 52, and 86 weeks postrandomization were analyzed with bifactor modeling. RESULTS: General psychopathology factor scores decreased across treatment and one-year follow-up. Specific melancholic features and depressive cognitions factors decreased from baseline to 6 weeks. Conduct problems decreased across treatment and follow-up. Anxiety increased by 6 weeks and then reverted to baseline levels. Obsessions-compulsions did not change. Changes in general and specific factors were not significantly different between the three psychotherapies during treatment. During follow-up, however, conduct problems decreased more in brief psychosocial intervention versus cognitive behavioral therapy (1.02, 95% Bayes credible interval 0.25, 1.96), but not versus short-term psychoanalytic psychotherapy. CONCLUSIONS: The clinical response signature in this trial is best revealed by rapid reductions in depression symptoms and general psychopathology. Protracted improvements in general psychopathology and conduct problems subsequently occur. Psychosocial treatments for adolescent depression have comparable effects on general and specific psychopathology, although a psychoeducational, goal-focused approach may be indicated for youth with comorbid conduct problems.

Attachment security differs by later autism spectrum disorder: A prospective study.

Although difficulties with social relationships are key to autism spectrum disorder (ASD), no previous study has examined infant attachment security prior to ASD diagnosis. We prospectively assessed attachment security at 15 months in high-risk infants with later ASD (high-risk/ASD, n = 16), high-risk infants without later ASD (high-risk/no-ASD, n = 40), and low-risk infants without later ASD (low-risk/no-ASD, n = 39) using the Strange Situation Procedure. High-risk/ASD infants were disproportionately more likely to be classified as insecure (versus secure) and more likely to be classified as insecure-resistant (versus secure or avoidant) than high-risk/no-ASD and low-risk/no-ASD infants. High-risk infants with insecure-resistant attachments were over nine times more likely to receive an ASD diagnosis than high-risk infants with secure attachments. Insecure-resistant attachment in high-risk infants suggests a propensity toward negative affect with the parent in conditions of stress. Insecure-resistant attachment may prove useful as a potential early index of propensity toward ASD diagnosis in high-risk siblings, while insecure-resistant attachment in the context of emergent autism may contribute to difficulties experienced by children with ASD and their families.

Antecedents of attachment states of mind in normative-risk and high-risk caregiving: cross-race and cross-sex generalizability in two longitudinal studies.

BACKGROUND: Longitudinal investigations of relatively large typical-risk (e.g., Booth-LaForce & Roisman, 2014) and higher-risk samples (e.g., Raby et al., 2017; Roisman et al., 2017) have produced evidence consistent with the claim that attachment states of mind in adolescence and young adulthood, as measured by the Adult Attachment Interview (AAI), are associated with the quality of caregiving experienced during childhood. None of these studies, however, has examined whether such associations are consistent across sex and/or race, as would be expected in light of the sensitivity hypothesis of attachment theory. METHODS: We examine whether sex or race moderates previously reported links between caregiving and AAI states of mind in two longitudinal studies (pooled N = 1,058) in which caregiving was measured either within (i.e., observed [in]sensitive care) or outside (i.e., childhood maltreatment) of the normative range of caregiving experiences. RESULTS: Hierarchical moderated regression analyses in both longitudinal cohorts provided evidence that maternal insensitivity and experiences of maltreatment were prospectively associated with dismissing and preoccupied states of mind in adolescence, as hypothesized. Moreover, these associations were generally comparable in magnitude for African American and White/non-Hispanic participants and were not conditional on participants' biological sex. CONCLUSIONS: Both maternal insensitivity and the experience of maltreatment increased risk for insecure attachment states of mind in adolescence. Moreover, our analyses provided little evidence that either participant race or participant sex assigned at birth moderated these nontrivial associations between measures of the quality of experienced caregiving and insecure attachment states of mind in adolescence. These findings provide support for the sensitivity hypothesis of attachment theory and inform the cultural universality hypothesis of attachment processes.

Refining the assessment of disrupted maternal communication: Using item response models to identify central indicators of disrupted behavior.

The Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; Bronfman, Madigan, & Lyons-Ruth, 2009-2014; Bronfman, Parsons, & Lyons-Ruth, 1992-2004) is a widely used and well-validated measure for assessing disrupted forms of caregiver responsiveness within parent-child interactions. However, it requires evaluating approximately 150 behavioral items from videotape and extensive training to code, thus making its use impractical in most clinical contexts. Accordingly, the primary aim of the current study was to identify a reduced set of behavioral indicators most central to the AMBIANCE coding system using latent-trait item response theory (IRT) models. Observed mother-infant interaction data previously coded with the AMBIANCE was pooled from laboratories in both North America and Europe (N = 343). Using 2-parameter logistic IRT models, a reduced set of 45 AMBIANCE items was identified. Preliminary convergent and discriminant validity was evaluated in relation to classifications of maternal disrupted communication assigned using the full set of AMBIANCE indicators, to infant attachment disorganization, and to maternal sensitivity. The results supported the construct validity of the refined item set, opening the way for development of a brief screening measure for disrupted maternal communication. IRT models in clinical scale refinement and their potential for bridging clinical and research objectives in developmental psychopathology are discussed.

Joint trajectories of depression and perfectionism across adolescence and childhood risk factors.

The codevelopment of symptoms of depression and socially prescribed perfectionism across adolescence (age 12-17) and non-age-overlapping childhood predictors (age 10-11) of joint trajectory group membership were examined in a sample of 700 Canadian youth. Results indicated that most adolescents (75.8%) followed a trajectory of low depression symptoms (low stable), whereas 15.7% followed an increasing trajectory (increasing), and 8.5% followed a trajectory that began high and decreased over time (high decreasing). More girls than boys were found in the increasing and high decreasing depression trajectories. Adolescents followed three distinct trajectories of socially prescribed perfectionism: 41.6% were in a low stable group, 40.5% in a moderate increasing group, and 17.9% in a high increasing group. Eight percent followed a high-risk dual trajectory of increasing depression and high increasing socially prescribed perfectionism. This joint trajectory was predicted by being bullied, anxious, and relationally aggressive (compared to the low-risk trajectory of low stable depression and perfectionism) at ages 10 and 11. These same predictors, along with poorer family functioning and lower family income, differentiated the joint high decreasing depression/high increasing perfectionism group from the low/low joint group, which comprised of 3.8% of the sample. The developmental progression was best characterized as depression leading to socially prescribed perfectionism. Implications for clinical practice are discussed.

Attachment states of mind and inferred childhood experiences in maltreated and comparison adolescents from low-income families.

This paper reports the first large-sample investigation of the maltreatment-related correlates of low-income adolescents' narratives about their childhood experiences with primary caregivers, as assessed with a modified version of the Adult Attachment Interview (AAI) and based on official reports of abuse and neglect (maltreated n = 214, nonmaltreated n = 140; M age = 16.7 years). Drawing on factor-analytic and taxometric evidence indicating that AAI narratives vary along two state of mind (i.e., dismissing and preoccupied) and two inferred childhood experience (i.e., maternal and paternal) dimensions, here we demonstrate that the experience of maltreatment, particularly when chronic, is associated with increased risk for dismissing and preoccupied states of mind and more negative inferred childhood experiences. Although such maltreatment-related associations were generally not specific to any of the four AAI dimensions, the experience of physical and/or sexual abuse was uniquely associated with preoccupied states of mind and negative inferred paternal experiences even after controlling for the other AAI dimensions. More extensive paternal perpetration of maltreatment also was uniquely related to more negative inferred paternal experiences.

Joint trajectories of internalizing and externalizing problems in preschool children with autism spectrum disorder.

The co-occurring development of internalizing and externalizing problems were examined in an inception cohort of 392 children diagnosed with autism spectrum disorder at age 3 who were assessed on four occasions. Results indicated that internalizing and externalizing problems were stable over time and highly comorbid. Joint trajectory analysis suggested that 13% of the sample followed a dual high-risk trajectory. High risk was not found to be associated with intellectual ability or autism spectrum disorder symptom severity but was linked to lower income and gender: more girls than boys were found in the high/stable internalizing problems trajectory. The results suggest that 1 in 4 preschoolers followed a trajectory of internalizing or externalizing problems (or a combination of the two) that could be characterized as clinically elevated.

Correlates of Childhood vs. Adolescence Internalizing Symptomatology from Infancy to Young Adulthood.

In light of its associations with child and adolescent health and well-being, there remains a need to better understand the etiological underpinnings and developmental course of internalizing symptomatology in children and adolescents. This study leveraged intensive longitudinal data (N = 959; 49.6 % females) to test the hypothesis that internalizing symptoms in childhood may be driven more strongly by family experiences whereas internalizing symptoms in adolescence may derive more uniquely from familial loading for affective disorders (i.e., maternal depression). We evaluated the relative contributions of (a) family experiences (b) maternal depression, and (c) peer influences in testing this hypothesis. The results indicated that family predictors were more strongly correlated with childhood (relative to adolescent) internalizing symptoms. In contrast to previous findings, maternal depression also exhibited stronger associations with childhood internalizing symptoms. Although often overlooked in theories concerning potential differential origins of childhood vs. adolescent internalizing symptomatology, peer experiences explained unique variation in both childhood and adolescent internalizing problems.

Strategic considerations in the search for transactional processes: Methods for detecting and quantifying transactional signals in longitudinal data.

Over the last four decades the transactional model has emerged as a central fixture of modern developmental science. Despite this, we are aware of no principled approach for determining (a) whether it is actually necessary to invoke transactional mechanisms to explain observed patterns of stability in a given domain of adaptive functioning and (b) the extent to which transactional processes, once identified in aggregate, are accounted for by measured domains with which an aspect of adaptive functioning is theoretically in transaction. Leveraging the fact that transactional mechanisms produce excess stability in an outcome domain above and beyond autoregressive processes, along with the basic logic of mediational analysis, we introduce two novel indexes for studying transactional processes strategically. We apply these metrics to data from the NICHD Study of Early Child Care and Youth Development cohort on mother- and teacher-reported externalizing problems and social competence along with teacher-reported and objective assessments of academic skills acquired in Grades 1, 3, and 5. During this developmental period we find that (a) transactional contributions to stability are strongest for teacher-reported outcomes, next strongest for mother-reported outcomes, and relatively weak for objective assessments of academic skills and (b) observed maternal sensitivity (but not child-reported friendship quality) accounts for a modest proportion of the total transactional effects operative in most of the domains of adaptive functioning we studied. Discussion focuses on extending the logic of our approach to additional waves of measurement.

Identifying Trajectories of Borderline Personality Features in Adolescence: Antecedent and Interactive Risk Factors.

OBJECTIVE: To examine trajectories of adolescent borderline personality (BP) features in a normative-risk cohort (n = 566) of Canadian children assessed at ages 13, 14, 15, and 16 and childhood predictors of trajectory group membership assessed at ages 8, 10, 11, and 12. METHOD: Data were drawn from the McMaster Teen Study, an on-going study examining relations among bullying, mental health, and academic achievement. Participants and their parents completed a battery of mental health and peer relations questionnaires at each wave of the study. Academic competence was assessed at age 8 (Grade 3). Latent class growth analysis, analysis of variance, and logistic regression were used to analyze the data. RESULTS: Three distinct BP features trajectory groups were identified: elevated or rising, intermediate or stable, and low or stable. Parent- and child-reported mental health symptoms, peer relations risk factors, and intra-individual risk factors were significant predictors of elevated or rising and intermediate or stable trajectory groups. Child-reported attention-deficit hyperactivity disorder (ADHD) and somatization symptoms uniquely predicted elevated or rising trajectory group membership, whereas parent-reported anxiety and child-reported ADHD symptoms uniquely predicted intermediate or stable trajectory group membership. Child-reported somatization symptoms was the only predictor to differentiate the intermediate or stable and elevated or rising trajectory groups (OR 1.15, 95% CI 1.04 to 1.28). Associations between child-reported reactive temperament and elevated BP features trajectory group membership were 10.23 times higher among children who were bullied, supporting a diathesis-stress pathway in the development of BP features for these youth. CONCLUSIONS: Findings demonstrate the heterogeneous course of BP features in early adolescence and shed light on the potential prodromal course of later borderline personality disorder.

Infant attachment, adult attachment, and maternal sensitivity: revisiting the intergenerational transmission gap.

This study investigated the intergenerational transmission of attachment, utilizing the Adult Attachment Interview (AAI), the Strange Situation Procedure (SSP), and the Maternal Behavioral Q-Set (MBQS). We revisited fundamental questions in attachment theory and research by examining: (1) the level of intergenerational agreement between maternal attachment representations and infant attachment security, and (2) whether maternal sensitivity serves as an intergenerational mediator between adult and infant attachment security. Significant categorical matches between the AAI and the SSP as well as mean differences for MBQS scores between adult attachment secure-insecure groups were found. Consistent with earlier intergenerational research, maternal sensitivity only partially mediated the AAI-SSP link, indicating the transmission gap remains. Consistent with recent mediation studies, using more contemporary analytical techniques, it was confirmed that maternal sensitivity did mediate the direct pathway between AAI security and SSP security. Thus, the transmission gap appears somewhat different depending on the statistical method used to measure mediation. Post hoc analyses considered mothers' childhood experiences of separation/divorce and this helped make sense of intergenerational mismatches.

Antecedents of maternal sensitivity during distressing tasks: integrating attachment, social information processing, and psychobiological perspectives.

Predictors of maternal sensitivity to infant distress were examined among 259 primiparous mothers. The Adult Attachment Interview, self-reports of personality and emotional functioning, and measures of physiological, emotional, and cognitive responses to videotapes of crying infants were administered prenatally. Maternal sensitivity was observed during three distress-eliciting tasks when infants were 6 months old. Coherence of mind was directly associated with higher maternal sensitivity to distress. Mothers' heightened emotional risk was indirectly associated with lower sensitivity via mothers' self-focused and negative processing of infant cry cues. Likewise, high physiological arousal accompanied by poor physiological regulation in response to infant crying was indirectly associated with lower maternal sensitivity to distress through mothers' self-focused and negative processing of infant cry cues.

Infant attachment insecurity and dissociative symptomatology: findings from the NICHD Study of Early Child Care and Youth Development.

Based on data from the NICHD Study of Early Child Care and Youth Development (N = 1,149), the current article provides the first large-sample investigation of associations between different forms of infant attachment insecurity and dissociative symptomatology from childhood through midadolescence as measured by scales based on the mother, teacher, and youth self-report versions of the Achenbach System of Empirically Based Assessments. Findings did not replicate the previously reported and highly cited evidence that infant attachment disorganization is associated with dissociative symptomatology. In contrast, correlations of small magnitude were observed between infant avoidance and dissociative symptomatology, as assessed by teachers and mothers (but not self-report). Results were not moderated by contextual risk. Limitations of the study included the absence of measures of maltreatment and interpersonal trauma, leaving open the possibility that infant attachment disorganization is a diathesis for later dissociation in the context of severe and/or chronic trauma. Nevertheless, the present results strongly indicate the need for additional research exploring the possible role of environmental factors in the development of dissociative symptomatology.
