Increasing diversity in neuroimaging research: Participant-driven recommendations from a qualitative study of an under-represented sample.

Enhancing the generalizability of neuroimaging studies requires actively engaging participants from under-represented communities. This paper leverages qualitative data to outline participant-driven recommendations for incorporating under-represented populations in neuroimaging protocols. Thirty-one participants, who had participated in neuroimaging research or could be eligible for one as part of an ongoing longitudinal study, engaged in semi-structured one-on-one interviews (84 % under-represented ethnic-racial identities and low-income backgrounds).

A thematic analysis of stress, substance-cue, and neutral/relaxing events to inform approaches for improving treatment among Black adults who use substances.

Introduction: To inform approaches for adapting substance use treatment for Black adults, the aim of this study was to thematically analyze the stressors, triggers for substance use, and neutral/relaxing events reported among Black adults who participated in a lab paradigm.

Methods: The sample included 36 Black adults (mean age [years] = 37.47, SD = 7.

What's race got to do with it? Factors contributing to self-change from cocaine use disorder among Black adults.

Introduction: A substantial number of people with substance use disorders recover without formal treatment, though we know little about the process of self-change among Black adults with cocaine use disorder (CUD) and whether racism contributes to the development of CUD and these adults' process of self-change.

Methods: The study team conducted qualitative interviews with 29 Black adults using a narrative and phenomenological approach. At the time of the interview, all participants met criteria for DSM-5 CUD prior to the past year but did not meet criteria for CUD in the past year and reported that they reduced their cocaine use without formal treatment.

The System for Coding Interactions and Family Functioning (SCIFF) in low-income and urban adolescents.

Reliable, brief, and cost-effective methods to assess parenting are critical for advancing etiological research and translational efforts within parenting science. In the current study, we adapted the System for Coding Interactions and Family Functioning (SCIFF) for use among a sample of mostly racial minority adolescents aged 15 years old, growing up in a low-income urban setting. A multiethnic team coded videotapes of a family interaction task designed to elicit conflict.

Effects of Parenting and Community Violence on Aggression-Related Social Goals: a Monozygotic Twin Differences Study.

Community violence exposure and harsh parenting have been linked to maladaptive outcomes, possibly via their effects on social cognition. The Social Information Processing (SIP) model has been used to study distinct socio-cognitive processes, demonstrating links between community violence exposure, harsh parenting, and maladaptive SIP. Though much of this research assumes these associations are causal, genetic confounds have made this assumption difficult to rigorously test.

The role of ventral striatum in reward-based attentional bias.

Introduction: Models of attention suggest that endogenous and exogenous factors can bias attention. However, recent data suggest that reward can also enhance attention towards relevant stimulus features as a function of involuntary biases. In this study, we utilized the additional singleton task to determine the neural circuitry that biases perceptual processing as a function of reward history.

Neural Correlates of the Propensity for Retaliatory Behavior in Youths With Disruptive Behavior Disorders.

Objective: Youths with disruptive behavior disorders (DBD) (conduct disorder and oppositional defiant disorder) have an elevated risk for maladaptive reactive aggression. Theory suggests that this is due to an elevated sensitivity of basic threat circuitry implicated in retaliation (amygdala/periaqueductal gray) in youths with DBD and low levels of callous-unemotional traits and dysfunctional regulatory activity in the ventromedial prefrontal cortex in youths with DBD irrespective of callous-unemotional traits.

Method: A total of 56 youths 10-18 years of age (23 of them female) participated in the study: 30 youths with DBD, divided by median split into groups with high and low levels of callous-unemotional traits, and 26 healthy youths.
