Dynamic of Change in Pathological Personality Trait Dimensions: A Latent Change Analysis Among at-Risk Women

Neuroendocrine and autonomic stress systems activity in young adults raised by mothers with mental health and substance abuse problems: A prospective cohort study

Among the well-known physiological consequences of early adverse environments is dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. A number of studies demonstrate that negative parenting and living with parents with a history of substance abuse and mental health problems may be associated with HPA axis dysregulation in children. In contrast, studies of more delayed effects in adult offspring, especially prospective, are still scarce. This study was a prospective longitudinal investigation of the association between maternal mental illnesses/substance abuse and maternal negative parenting/parental stress on one side and, on the other side, adult offspring outcomes 10 years later-specifically, we studied the activity of offspring's neuroendocrine (cortisol) and autonomic (heart rate) systems when exposed to a mild psychological stressor. Children of mothers with mental illnesses and/or substance abuse were exposed to more disadvantaged conditions (higher negative parenting and community violence). Despite this, maternal risk groups (having a mother with mental illnesses and/or substance abuse) were not associated with any of the indicators of stress systems activity. Regardless of the risk group, participants with dysregulated HPA axis activity experienced a higher level of negative parenting. Altogether, our study provides evidence that negative parenting may have long-lasting effects on stress-sensitive physiological mechanisms.

Diagnostic Agreement Between Clinicians and Clients: The Convergent and Discriminant Validity of the SWAP-200 and MCMI-III Personality Disorder Scales

A particularly controversial aspect in the field of personality assessment is the use of self-report measures, versus clinicians' evaluations, for diagnosing personality disorder (PD). No studies have systematically documented the agreement between these sources for the entire array of DSM-5 PDs using comprehensive measures and experienced clinicians' judgments. The present work fills this gap by indexing the agreement between patients' self-descriptions and clinicians' judgments, relying on standardized and thorough PD instruments. The Shedler-Westen Assessment Procedure-200 (SWAP-200; Westen & Shedler, 1999a, 1999b) and the Millon Clinical Multiaxial Inventory-III (Millon, Davis, & Millon, 1997) were both completed in a clinical series of 56 adult outpatients. Analyses highlighted moderate correlations between the two measures for the 10 DSM-5 PDs (Mdn = .35). Agreement was highest for psychological features that are more easily observable by the clinicians. Furthermore, results revealed problematic discriminant validity between the two instruments.

Changes in mental health outcomes with the intensive in-home child and adolescent psychiatric service: a multi-informant, latent consensus approach

This study investigates the Intensive In-home Child and Adolescent Psychiatric Service (IICAPS), a large-scale home-based intervention that collaboratively engages the family, school, and various other service providers (e.g. health practitioners or judicial systems) to prevent the hospitalization, institutionalization or out-of-home placement of children and adolescents with serious emotional disturbance. Multi-informant data (youth, parents and clinician) on the level of youth problem severity and functioning was gathered from 7169 youth and their families served by the IICAPS network, pre- and post-intervention. A newly developed "Multi-informant Latent Consensus" (MILC) approach was employed to measure mental health "baseline levels" and change, within a Structural Equation Modeling framework. The MILC approach demonstrated promise integrating information from multiple informants involved in the therapeutic process to yield a more accurate and systemic view of a child's level of functioning and problem severity than each report taken individually. Results indicated that the IICAPS family and community based intervention model led to a reduction of problem severity and improved functioning in children and adolescents with severe emotional disturbance.

Reciprocal influences between maternal parenting and child adjustment in a high-risk population: a 5-year cross-lagged analysis of bidirectional effects

This study examines longitudinally the bidirectional influences between maternal parenting (behaviors and parenting stress) and mothers' perceptions of their children's adjustment, in a multivariate approach. Data was gathered from 361 low-income mothers (many with psychiatric diagnoses) reporting on their parenting behavior, parenting stress, and their child's adjustment, in a 2-wave longitudinal study over 5 years. Measurement models were developed to derive 4 broad parenting constructs (involvement, control, rejection, and stress) and 3 child adjustment constructs (internalizing problems, externalizing problems, and social competence). After measurement invariance of these constructs was confirmed across relevant groups and over time, both measurement models were integrated in a single crossed-lagged regression analysis of latent constructs. Multiple reciprocal influences were observed between parenting and perceived child adjustment over time: Externalizing and internalizing problems in children were predicted by baseline maternal parenting behaviors, and child social competence was found to reduce parental stress and increase parental involvement and appropriate monitoring. These findings on the motherhood experience are discussed in light of recent research efforts to understand mother-child bidirectional influences and their potential for practical applications.

Capturing Age-group Differences and Developmental Change with the BASC Parent Rating Scales

Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998), Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. Importance of test-content parallelism for developmental studies is discussed.
