Novel genome-wide associations for effort valuation and psychopathology in children and adults.

The Research Domain Criteria (RDoC) initiative was established by the US National Institute of Mental Health as a multilevel, disorder-agnostic framework for analysis of human psychopathology through designated domains and constructs, including the "Positive Valence Systems" domain focused on reward-related behavior. This study investigates the reward valuation subconstruct of "effort" and its association with genetic markers, functional neurobiological pathways, and polygenic risk scores for psychopathology in 1215 children aged 6-12 and their parents (n = 1044). All participants completed the effort expenditure for rewards task (EEfRT), which assesses "effort" according to two quantitative measures: hard-task choice and reward sensitivity. Genetic association analyses were undertaken in MAGMA, utilizing EEfRT outcome variables as genome-wide association studies phenotypes to compute SNP and gene-level associations. Genome-wide association analyses found two distinct genetic loci that were significantly associated with measures of reward sensitivity and a separate genetic locus associated with hard task choice. Gene-set enrichment analysis yielded significant associations between "effort" and multiple gene sets involved in reward processing-related pathways, including dopamine receptor signaling, limbic system and forebrain development, and biological response to cocaine. These results serve to establish "effort" as a relevant construct for understanding reward-related behavior at the genetic level and support the RDoC framework for assessing disorder-agnostic psychopathology.

It's Not Only Vaccine Hesitancy; It's Also Physician Hesitancy.

The danger of vaccine hesitancy is perhaps one of the most critical challenges we face as practitioners. This riveting narrative helps us find common ground and courage as it reaches into the hearts of those of us who have encountered parents who also want what's best for their child.

Initial Responsiveness to Reward Attainment and Psychopathology in Children and Adults: An RDoC Study.

The Research Domain Criteria (RDoC) initiative of the National Institute of Mental Health (NIMH) established a dimensional framework for understanding psychiatric constructs. Initial Responsiveness to Reward Attainment (IRRA) was identified as a dimensional construct relevant to several psychiatric disorders. The current study aimed to (1) examine IRRA as a predictor of psychopathology and impairment in children and their parents, and (2) examine the potential effects of sex and ancestry on the relationship between IRRA and psychopathology. Participants included 1127 children ages 6 to 12, and 1018 of their parents. Parents and children completed self-report measures of IRRA. Psychopathology and impairment were measured using self-report for adults, and parent-report and semi-structured interview for children. In adults, IRRA was significantly, but modestly, related to adaptive functioning. In children, IRRA was significantly, but modestly, related to overall, school, spare time, home, and peer functioning. Findings suggest IRRA may be a helpful construct for understanding adaptive functioning in adults and children, however it may be less helpful for understanding specific dimensions of psychopathology. Additionally, ancestry should be taken into consideration when examining how IRRA relates to psychopathology and functioning.

Effort valuation and psychopathology in children and adults.

BACKGROUND: The Research Domain Criteria initiative was launched by the US National Institute of Mental Health to establish a multi-level framework for understanding psychological constructs relevant to human psychiatric disorders, and identified 'effort valuation/willingness to work' as a clinically useful construct worthy of further study. This construct encompasses the processes by which the cost(s) of obtaining an outcome are calculated, and the tendency to overcome response costs to obtain a reinforcer. The current study aims to examine effort valuation as a correlate of psychopathology in children and adults, and the moderating effects of sex on this relationship. METHODS: Participants were 1215 children aged 6-12 and their parents (n = 1044). All participants completed the Effort Expenditure for Rewards Task as a measure of effort expenditure. Child psychopathology was measured via the Child Behavior Checklist, while adult psychopathology was measured via the Adult Self Report. Additionally, the Social Adjustment Inventory for Children and Adolescents and Injury Behavior Checklist were used to examine child social impairments/problem behaviors. RESULTS: In children, significant interactions between reward sensitivity and sex were observed in association with anxiety and thought problems, specifically at low reward sensitivity levels. In adults, main effects of effort expenditure were seen in drug and alcohol abuse, where higher effort was associated with higher degrees of abuse. CONCLUSIONS: These results establish effort valuation as a relevant psychological construct for understanding psychopathology, but with different profiles of associated psychopathology across sex in children and adults.

Toward the development of advocacy training curricula for pediatric residents: a national delphi study.

BACKGROUND: Training in child advocacy is now required in pediatric residency program curricula. No national consensus exists regarding the content of such advocacy training. OBJECTIVE: To identify an operational definition of advocacy, as well as knowledge, skills, and attitude objectives for advocacy training in pediatric residency programs. METHODS: Professionals experienced in pediatric advocacy and training (n = 53) were invited to participate in a sequence of surveys to define the content of a pediatric residency advocacy curriculum that would result in acquisition of appropriate knowledge, skills, and attitudes related to advocacy for children. Three rounds of surveys were distributed, collected, and analyzed using a modified Delphi technique, in which the results from an antecedent survey were used to refine responses in a subsequent survey. RESULTS: Participants (n = 36), comprising a group of experienced leaders with diverse training and experience in child advocacy and resident education, created a consensus definition for advocacy. They initially identified 179 possible objectives for advocacy curricula. Through the iterative process of the Delphi technique, 32 of those objectives were identified as necessary for inclusion in a child advocacy curriculum for pediatric residents. CONCLUSIONS: Using a modified Delphi technique, a group of experienced leaders in pediatric advocacy were able to reach consensus on an operational definition of child advocacy and a set of objectives for a resident advocacy curriculum. Programs may use these findings to assist in developing an advocacy curriculum based on their own faculty assets and community resources.
