Implicit Encouragement: Enhancing Youth Productivity when Recounting a Stressful Experience

Rapport building with adolescents to enhance reporting and disclosure

Adolescents comprise a vulnerable population that is exposed to crime and also may be reluctant to disclose full details of their experiences. Little research has addressed effective ways of increasing their willingness to disclose and provide complete reports. Strategies that improve honesty and report completeness in other age groups have not been evaluated to determine whether they are similarly effective at increasing adolescents' reporting. In the current study, we tested whether rapport building techniques, modified from those commonly used with children and adults to address reasons why adolescents are likely reluctant, enhance the amount of detail adolescents provide about prior experiences. The participants, 14- to 19-year-olds (N = 125), completed an online questionnaire regarding significant events (e.g., big argument with family member) they experienced during the last 12 months. After a delay, they completed a remote interview asking them to recount details of one of the events. The interview began with either standard rapport building composed of largely yes/no questions about the adolescents' background or one of two expanded rapport building phases: open-ended (questions about the adolescents' backgrounds that required narrative answers) or enhanced (open-ended questions paired with the interviewer also sharing personal information). Although only adolescents in the standard condition showed age-related increases in information disclosed, overall adolescents in the enhanced condition provided significantly longer and more detailed narratives than adolescents in the other conditions. This effect was largest for the youngest adolescents, suggesting that mutual self-disclosure may be especially beneficial for eliciting honest complete reports from adolescents about salient prior experiences.

Stress and working memory in children and adolescents: Insights from a multisystem approach

Despite considerable research with adults suggesting that acute stress negatively affects working memory (WM), a core cognitive function, few studies have assessed these effects in youths. Studies that have been conducted have produced null findings, although these studies did not measure stress via multiple systems (e.g., hypothalamic-pituitary-adrenal [HPA] axis and sympathetic nervous system [SNS]) or include wide developmental age ranges. In the current study, we examined the links between acute stress and WM in 8- to 15-year-olds. Youths completed the Trier Social Stress Test-Modified, during which repeated saliva samples were collected to measure responses of the HPA axis (cortisol) and SNS (salivary alpha-amylase). Immediately afterward, youths completed the n-back task, an established measure of WM. Accuracy and false alarm (FA) scores were computed to explore whether associations between arousal and WM differed when WM versus only the inhibitory control facet of WM processes were considered. Relations varied as a function of age, physiological system, and type of WM process. Accuracy improved and FA scores deceased as age and SNS reactivity increased, particularly in combination. Moreover, when arousal was higher according to only one physiological system (HPA axis or SNS), FA scores were lower, but when arousal was driven by both systems or low in both systems, FA scores were higher. Together, results highlight the need for more complex investigations of stress and WM across development that take into account system-specific responses and multiple facets of WM.
