Making it "EASI" for pediatricians to determine when toddler tantrums are "more than the terrible twos": Proof-of-concept for primary care screening with the Multidimensional Assessment Profiles-Early Assessment Screener for Irritability (MAPS-EASI).

BACKGROUND: Up to 20% of youth have impairing mental health problems as early as age 3. Early identification and intervention of mental health risks in pediatric primary care could mitigate this crisis via prevention prior to disease onset. The purpose of this study was to establish the feasibility and acceptability of implementing a brief transdiagnostic screening instrument in pediatric primary care for irritability and corollary impairment. METHOD: Five pediatric clinicians in a Midwest clinic implemented the Multidimensional Assessment Profiles-Early Assessment Screener of Irritability (MAPS-EASI) for toddlers (24-30 months) and their families. MAPS-EASI (psychometrically derived from the well-validated MAPS-Scales) includes six items (scored 0-5) about symptoms (e.g., tantrums, grumpy mood), context, and frequency and two items (scored 0-3) assessed impairment. Positive screens (MAPS-EASI ≥ 5 plus impairment ≥ 2) were referred to an evidence-based parenting intervention. We assessed reach and outcomes of MAPS-EASI screening. Follow-up interviews with clinicians assessed perspectives on irritability screening and MAPS-EASI implementation. RESULTS: Of 201 eligible families, 100 (49.8%) completed the screener for a 24- or 30-month well-child visit. Mean MAPS-EASI scores were 5.8 (SD = 3.2), mean impairment scores were 0.9 (SD = 0.9), and 24 (24.0%) screened positive. Clinicians indicated that irritability screening for toddlers was aligned with their prevention-oriented, developmentally based practice. MAPS-EASI had face validity and increased clinician decision-making confidence. Finally, clinicians identified barriers and facilitators to large-scale implementation. CONCLUSIONS: MAPS-EASI proved to be feasible and acceptable in pediatric primary care. Further tailoring will be needed as the MAPS-EASI processes are scaled out to new contexts and populations.

Toward an optimized assessment of adolescent psychopathology risk: Multilevel environmental profiles and child irritability as predictors.

Background: Adolescence is a developmental period during which youth experience vulnerability to psychopathology. To build the foundation for a parsimonious psychopathology risk calculator while capturing the complexity and dynamic nature of the environment, the current study aimed to identify distinct risk and resilience profiles with a wide range of environmental factors guided by Bronfenbrenner's biopsychosocial ecological system theory. The association between the early-mid childhood risk profiles and psychopathology in adolescence were examined. Moreover, the predictive utility of early childhood irritability was evaluated in addition to the risk profiles. Methods: The data from Future of Families and Child Wellbeing Study a nation-wide longitudinal study, were used in the latent profile analyses to identify the risk profiles with family, school, and neighborhood characteristics from 3 to 9 years old. To capture the socio-environmental and cultural nuances, we extracted three subsamples, including Black/African American (n = 2587), Hispanic/Latinx (n = 1577), and White (n = 776) for separate analyses. Risk profile memberships were used to predict adolescence psychopathology, including depression, anxiety, attention deficits, oppositional defiant disorder, and conduct disorder symptoms. The predictive utility of early childhood irritability above and beyond environmental risk profiles was evaluated using stepwise regression. Results: Three risk profiles were identified in the Hispanic/Latinx and Black/African American subsamples, while four profiles were identified in White subsample. Almost all risk profile membership predicted both internalizing and externalizing psychopathology, while some profiles are predictive of externalizing symptoms only. Higher level of irritability predicted higher symptomatology in all five mental health outcomes above and beyond the environmental profiles. Conclusions: Distinct risk and resilience profiles primarily driven by parent and family characteristics were identified for all three major race/ethnicity groups. Our findings lay the foundation for a more efficient multi-tiered information gathering process in mental health clinical settings to aid the decision making for intervention and prevention.

Developmentally specified characterization of the irritability spectrum at early school age: Implications for pragmatic mental health screening.

OBJECTIVES: Developmentally specified measures that identify clinically salient irritability are needed for early school-age youth to meaningfully capture this transdiagnostic risk factor for psychopathology. Thus, the current study modeled the normal:abnormal irritability spectrum and generated a clinically optimized screening tool for this population. METHODS: The irritability spectrum was modeled via the youth version of the Multidimensional Assessment Profile Scales-Temper Loss Scale (MAPS-TL-Youth) in children (n = 474; 6.0-8.9 years) using item response theory (IRT). Both cross-cutting core irritability items from the early childhood version and new developmentally specific items were included. Items uniquely associated with impairment were identified and used to derive a brief, clinically optimized irritability screener. Longitudinal data were then utilized to test the predictive utility of this clinically optimized screener in preadolescence (n = 348; 8.0-12.9 years). RESULTS: Most children exhibit irritability regularly, but daily occurrence was rare. Of the top 10 most severe items from the IRT analyses, 9 were from the developmentally specific items added for the MAPS-TL Youth version. Two items associated with concurrent impairment were identified for the clinically optimized irritability screener ("Become frustrated easily" and "Act irritable"). The MAPS-TL-Youth clinically optimized screener demonstrated good sensitivity (69%) and specificity (84%) in relation to concurrent DSM 5 irritability-related diagnoses. Youth with elevated scores on the screener at early school age (ESA) had more than 7x greater odds of irritability-related psychopathology at pre-adolescence. CONCLUSIONS: The MAPS-TL-Youth characterized the developmental spectrum of irritability at ESA and a clinically optimized screener showed promise at predicting psychopathology risk. Rigorous testing of clinical applications is a critical next step.

Neural correlates of attachment in adolescents with trauma: a preliminary study on frustrative non-reward.

Despite the proposed early life origins of attachment style and its implications for risk for psychopathology, little is known about its neurodevelopmental course. Adolescence represents a key transition period when neural substrates of emotion regulation and reward undergo dramatic maturational shifts. Thus, maladaptive coping strategies associated with insecure attachment styles may have an exaggerated effect during adolescence. The current study, therefore, examined the neural correlates of insecure attachment in a diverse sample of adolescents using a frustrative non-reward task (i.e. repeatedly being denied an expected reward). Although there were no significant interactions in the whole-brain activation averaged over the course of the task, the use of complementary analytic approaches (connectivity, change in activation over the course of the task) revealed widespread alterations associated with avoidant attachment during the immediate reaction to, and ensuing recovery from, being denied a reward. Most strikingly, increased avoidant attachment, adjusting for anxious attachment, predicted functional connectivity and change in activity over time in amygdala-prefrontal and frontostriatal networks to reward blocked vs received trials. These patterns were in the opposite direction compared to those exhibited by adolescents lower in avoidant attachment. The findings suggest that negative emotional experiences, such as receiving frustrating feedback, may be uniquely aversive internal experiences for avoidantly attached adolescents and provide preliminary evidence that early coping strategies may persist into adolescence in the form of altered emotion- and reward-related neural patterns.

Neural mechanisms of reward processing in adolescent irritability.

Irritability is impairing and prevalent across pediatric psychiatric disorders and typical development, yet its neural mechanisms are largely unknown. This study evaluated the relation between adolescent irritability and reward-related brain function as a candidate neural mechanism. Adolescents from intervention-seeking families in the community (N = 52; mean age = 13.80, SD = 1.94) completed a monetary incentive delay task to assess reward anticipation and feedback (reward receipt and omission) during fMRI acquisition. Whole-brain analyses, controlling for age, examined brain activation and striatal and amygdala connectivity in relation to irritability. Irritability was measured using the parent- and youth-reported Affective Reactivity Index. Irritability was associated with altered reward processing-related activation and connectivity in multiple networks during reward anticipation and feedback, including increased striatal activation and altered ventral striatum connectivity with prefrontal areas. Our findings suggest that irritability is associated with altered neural patterns during reward processing and that aberrant prefrontal cortex-mediated top-down control may be related to irritability. These findings inform our understanding of the etiology of youth irritability and the development of mechanism-based interventions.

Lifespan differences in cortico-striatal resting state connectivity.

Distinctive cortico-striatal circuits that serve motor and cognitive functions have been recently mapped based on resting state connectivity. It has been reported that age differences in cortico-striatal connectivity relate to cognitive declines in aging. Moreover, children in their early teens (i.e., youth) already show mature motor network patterns while their cognitive networks are still developing. In the current study, we examined age differences in the frontal-striatal "cognitive" and "motor" circuits in children and adolescence, young adults (YAs), and older adults (OAs). We predicted that the strength of the "cognitive" frontal-striatal circuits would follow an inverted "U" pattern across age; children and OAs would have weaker connectivity than YAs. However, we predicted that the "motor" circuits would show less variation in connectivity strength across the lifespan. We found that most areas in both the "cognitive" and "motor" circuits showed higher connectivity in YAs than children and OAs, suggesting general inverted "U"-shaped changes across the lifespan for both the cognitive and motor frontal-striatal networks.
