Time-varying and time-invariant dimensions of depression in children and adolescents: Implications for cross-informant agreement

Time-Varying and Time-Invariant Dimensions in Intolerance of Uncertainty: Specificity in the Prediction of Obsessive-Compulsive Symptoms

Intolerance of uncertainty (IU) is the tendency to respond negatively toward uncertain situations. IU consists of a Prospective factor (desire for predictability) and an Inhibitory factor (uncertainty paralysis) and is central to theoretical approaches to obsessive-compulsive disorder (OCD). However, time-invariant (TI) and time-varying (TV) components of IU and their association with OCD symptoms are not yet understood. The present study examined the association between TI and TV components of IU and OCD symptoms in community adults (N = 1,280) over a 5-month period. Latent variable models were fit to the data to examine the relative impact of TI and TV components of IU on OCD symptoms. As a test of specificity, models examining the association between TI and TV components of IU and depressive symptoms were also examined. The results showed that IU consists of significant TI and TV components, although the TI component accounted for most of the variance (76-84%) and was more strongly associated with OCD and depressive symptoms than the TV component. Furthermore, the TI component of IU was strongly associated with OCD symptoms when controlling for depressive symptoms, and the TI component of IU was strongly associated with depressive symptoms when controlling for OCD symptoms. A consistent pattern was observed for both Prospective and Inhibitory IU factors, with stable TI components demonstrating stronger relations with OCD and depressive symptoms than TV components. These findings have implications for conceptualizing the TI component of IU as a risk for OCD and other emotional disorders.

Greek Validation of the Factor Structure and Longitudinal Measurement Invariance of the Strengths and Difficulties Questionnaire-Self Report (SDQ-SR): Exploratory Structural Equation Modelling

The study examined the factor structure and longitudinal measurement invariance over three time points (1-year apart) of the Strengths and Difficulties Questionnaire-Self Report (SDQ-SR) for ratings provided by adolescents in Greece. It used exploratory structural equation modelling (ESEM) to achieve these two goals. At time point one, a total of 968 adolescents (males = 508, and females = 460) between 12 and 17.9 years completed the SDQ-SR. In relation to factor structure, ESEM tested the fit of one- to five-factor models. The findings were interpreted as indicating most support for the ESEM model with three factors (the factors being dysregulation, peer problems, and prosocial behaviour). This model showed support for configural invariance and full metric invariance across the three time points. Except for two thresholds, all other thresholds were also invariant across the three time points. Thus, there was good support for longitudinal measurement invariance. The implications of the findings for use of the SDQ-SR are discussed.

Disentangling trait, occasion-specific, and accumulated situational effects of psychological distress in adulthood: evidence from the 1958 and 1970 British birth cohorts

BACKGROUND

The trajectories of psychological distress differ between individuals, but these differences can be difficult to understand because the measures contain both consistent and situational features; however, in longitudinal studies these sources of information can be disentangled. In addition to occasion-specific features, interindividual differences can be decomposed into two sources of information: trait and carry-over effects between neighboring occasions that are not related to the trait (i.e. accumulated situational effects).

METHODS

To disentangle these three sources of variance throughout adulthood, the consistency (trait and accumulated situational effects) and occasion specificity of nine indicators of psychological distress from the Malaise Inventory were examined in two birth cohorts, the 1958 National Child Development Study (NCDS58), and the 1970 British Cohort Study (BCS70).

RESULTS

The scale was administered at ages 23, 33, 42, and 50 in NCDS58 (n = 7147), and at ages 26, 30, 34, and 42 in BCS70 (n = 6859). For each psychological symptom, more variance was consistent than occasion-specific. The majority of the consistency was due to trait variance as opposed to accumulated situational effects, indicating that an individual predisposed to be distressed at the beginning of the study remained more likely to be distressed over the whole period. Symptoms of rage were notably more consistent among males than females in both cohorts (78.1% and 81.3% variance explained by trait in NCDS58 and BCS70, respectively), and among females in the NCDS58 (69%).

CONCLUSIONS

Symptoms of psychological distress exhibited high stability throughout adulthood, especially among men, due mostly to interindividual trait differences.

The unique effects of maternal and paternal depressive symptoms on youth's symptomatology: Moderation by family ethnicity, family structure, and child gender

Drawing on five waves of longitudinal data from 392 families (52% female; mean age of wave 1 [Mage_W1] = 12.89, standard deviation [SD] = .48; Mage_W5 = 21.95, SD = .77; 199 European American and 193 Mexican American families; 217 intact and 175 stepfather families), this study documented transactional relations of mothers' and fathers' depressive symptoms with youth's symptomatology from early adolescence to young adulthood. Trait and time-varying cross-lagged models revealed that both mothers' and fathers' between- and within-person differences in depressive symptoms were associated with youth's internalizing and externalizing symptoms. Whereas each parent's depressive symptoms uniquely contributed to youth's internalizing symptoms, however, only mothers' depressive symptoms influenced youth's externalizing symptoms. Although reciprocal effects of youth's internalizing symptoms on parents' depressive symptoms were not significant, youth's externalizing symptoms predicted changes in mothers' depressive symptoms over time. Moderation analyses revealed distinct transactional patterns by family ethnicity and child gender, but not by family structure. This study revealed dynamic transactions among family members' symptomatology that point to opportune times and targets for intervention efforts aimed at mitigating the negative impact of parents' depressive symptoms on youth's adjustment.

Informant Discrepancies in Internalizing and Externalizing Symptoms in an At-Risk Sample: The Role of Parenting and School Engagement

A number of studies have used variable-centered approaches to examine informant discrepancies on children's behavior problems; however, few such studies have used person-centered approaches to explore patterns of informant discrepancies or correlates of discrepancies in informant symptom ratings. The present study addressed these gaps by examining profiles of informant agreement on internalizing and externalizing symptoms and examining whether two important contextual factors, parenting and school engagement, are associated with profile membership. Data from an at-risk, urban sample of youth participants (N= 346, M age = 12.47 ± 0.60 years, 56% male, and 75% Black), their caregivers, and one of their teachers were analyzed in the current study. Youth from 20 schools in a Mid-Atlantic state were screened for elevated levels of aggression and were selected to participate in the Early Adolescent Coping Power study. At baseline, youth, caregivers, and teachers reported on youth's internalizing symptoms and caregivers and teachers reported on youth's externalizing symptoms. Caregivers reported on their parenting; youth reported on their school engagement. Two internalizing symptoms profiles were identified: Low Symptoms Agreement and Youth-Reported High Somatization and Anxiety. Three externalizing symptoms profiles were identified: Low Symptoms Agreement, Teacher-Reported High Externalizing, and Caregiver-Reported High Externalizing. These profiles differed significantly on parenting behaviors and school engagement, shedding light on factors that may underlie informant discrepancies.

Data Harmonization: Establishing Measurement Invariance across Different Assessments of the Same Construct across Adolescence

Longitudinal measurement invariance is a major concern for developmental scholars who seek to evaluate the same underlying construct across time. Unfortunately, discontinuities in the expression of various psychological constructs, as well as essential changes in measurement that are necessitated by shifting developmental capacities and practice effects over time, make the task of establishing longitudinal invariance extremely difficult. Drawing on 5 waves of longitudinal data from 392 families (52% female; M_{age_W1} = 12.89, SD = .48; M_{age_W5} = 21.95, SD = .77; 199 European American and 193 Mexican American families), the current investigation sought to establish measurement invariance across developmentally appropriate changes in measures of depressive symptomatology from early adolescence through early adulthood. Using a combination of item parceling and the common and unique items from 2 assessment instruments for depressive symptoms, the data supported strong factorial invariance in youth's depressive symptoms across 5 waves of measurement. Findings suggest that traditional invariance approaches can be adapted to determine whether the same construct underlies different measurement instruments across time. This analytic strategy can allow researchers and clinicians to use more sophisticated techniques to understand changes in symptomatology regardless of changes in measurement or developmental capacity. Applying this approach to model patterns of depressive symptomatology from early adolescence to early adulthood has important clinical implications for elucidating periods when youth experience elevations in depressive symptoms and heightened needs for intervention services.

Emotional and Behavioral Health Needs in Elementary School Students in an Underserved Hispanic Community

High rates of mental health problems in adolescents have been well documented; less is known about elementary school children in disadvantaged communities. We examined emotional and behavioral health needs in 202 third and fourth graders enrolled in a charter school in a largely Hispanic community. The child-reported Revised Child Anxiety and Depression Scale-25 and Teacher's Report Form were used to evaluate mental health needs as perceived by these children and their teachers. The prevalence of teacher-reported depression and child self-reported anxiety was 7.0% and 6.67%, respectively. Living in a single parent household was found to be a specific risk factor in that those children had higher rates of emotional and behavioral problems than children living with both parents. Evidence of higher depression and anxiety identified in this sample compared to national representative data suggests the need for development of culturally sensitive early prevention and intervention in this underserved community.

Problems with Rationales for Parceling that Fail to Consider Parcel-Allocation Variability

In structural equation modeling applications, parcels-averages or sums of subsets of item scores-are often used as indicators of latent constructs. Parcel-allocation variability (PAV) is variability in results that arises within sample across alternative item-to-parcel allocations. PAV can manifest in all results of a parcel-level model (e.g., model fit, parameter estimates, standard errors, and inferential decisions). It is a source of uncertainty in parcel-level model results that can be investigated, reported, and accounted for. Failing to do so raises representativeness and replicability concerns. However, in recent methodological literature (Cole, Perkins, & Zelkowitz, 2016 ; Little, Rhemtulla, Gibson, & Shoemann, 2013 ; Marsh, Ludtke, Nagengast, Morin, & von Davier, 2013 ; Rhemtulla, 2016 ) parceling has been justified and recommended in several situations without quantifying or accounting for PAV. In this article, we explain and demonstrate problems with these rationales. Overall, we find that: (1) using a purposive parceling algorithm for a multidimensional construct does not avoid PAV; (2) passing a test of unidimensionality of the item-level model need not avoid PAV; and (3) a desire to improve power for detecting structural misspecification does not warrant parceling without addressing PAV; we show how to simultaneously avoid PAV and obtain even higher power by comparing item-level models differing in structural constraints. Implications for practice are discussed.

Dynamic associations between borderline personality disorder and stressful life events over five years in older adults

The time course of borderline personality disorder (BPD) is far more variable than traditionally assumed. Shifting environmental conditions are theorized to account, at least in part, for fluctuations in symptom presentation over time. In the present study, we evaluated the reciprocal influences of stressful life events and borderline pathology in a representative community sample of 1,630 older adults assessed 3 times over 5 years. An autoregressive cross-lagged model revealed strong, but imperfect, stability in symptoms of BPD over the study time frame. After adjusting for this continuity in BPD, the prospective effect of life stress on borderline pathology was virtually nil, contrary to expectations. On the other hand, borderline pathology was prospectively related to subsequent dependent event (i.e., stressors to which individuals may have contributed), but not independent event (i.e., fateful stressors), exposure. This pattern of associations was consistent with a stress generation effect. We conclude that stressful life events do not substantially redirect the trajectory of BPD in older adults, possibly owing to inertia of borderline pathology at this developmental stage. Instead, symptoms of BPD seem to promote stress exposure, thereby setting the stage for continued social impairment and comorbid psychiatric problems.

Borderline personality disorder is equally trait-like and state-like over ten years in adult psychiatric patients

Borderline personality disorder (PD) has historically been cast as an unabating condition. Longitudinal data, however, support a more variable time course marked by remission and relapse. In the present study, we tested the possibility that borderline PD has both stable (i.e., consistently present across time and situation, as modern diagnostic systems stipulate) and dynamic (i.e., episodic and situational) elements. Participants were 668 patients from the Collaborative Longitudinal Personality Disorders Study who were administered semistructured diagnostic interviews 5 times over a decade. Trait-state-occasion modeling dissected borderline pathology into time-invariant (i.e., trait) and time-varying (i.e., state) components. Contradicting traditional views of PD intransigence, less than half of borderline PD variability (approximately 45%) was time-invariant (i.e., perfectly stable) over the study timeframe. Furthermore, we found that the time-invariant component of borderline pathology, which we termed borderline proneness, was very closely related (r = .81) to a previously validated Five Factor Model trait composite of borderline features. Moreover, the trait versus state components showed a clear pattern of discriminant validity in relation to several putative causal agents for borderline PD (i.e., environmental pathogens, temperament dimensions). We conclude that borderline pathology contains a stable core and sizable situational components, and that both elements relate systematically to normative personality dimensions and known risk factors. These findings have key implications for etiological research, prognosis, and treatment for borderline PD. (PsycINFO Database Record
