Observational StudyPromoting Resilience in Teens With ASD

The web-based growth mindset intervention, called Project Personality, is delivered entirely via Qualtrics and takes approximately 30 minutes to complete. All intervention activities are self-administered by youth and delivered in a web-based format, including illustrations and audio-recordings of text. Intervention content is designed to maximize relevance for youths experiencing symptoms of depression, including excessive sadness and hopelessness.

The Sharing Feelings Intervention is delivered entirely via Qualtrics, is self-administered by youth, and takes approximately 30 minutes to complete. It is structurally similar to the growth mindset intervention, but it is designed to mimic supportive therapy (ST). The goals of the ST intervention is to encourage youths to identify and express feelings to close others; the intervention does not teach or emphasize specific skills or beliefs. In previous clinical trials, ST has resulted in significantly fewer reductions in youth internalizing problems compared to cognitive-behavioral and growth mindset interventions.

The intervention includes five components: 1. An introduction to the brain, including a lesson on the concept of neuroplasticity, describing how and why our behaviors are controlled by thoughts and feelings in their brains, which have potential for change; 2. Written testimonials from older youths who describe their beliefs that people's personal traits (e.g., sadness, anxiety) are malleable, given the brain's plasticity; 3. Additional vignettes written by older youths, describing times when they used "growth mindsets" to persevere through social and emotional setbacks; 4. A summary of selected scientific studies suggesting that personality can, and often does, change in positive ways over time; and 5. An exercise in which the participants write notes to younger students, drawing on scientific information to describe the malleability of people's personal traits (i.e., a "self-persuasion" exercise).

The ST SSI is designed to control for nonspecific aspects of intervention, including engagement in a computer program. It includes the same number of reading and writing activities as the web-based growth mindset intervention; it also mirrors the web-based growth mindset intervention as closely as possible, including vignettes written by older youths who describe times when they benefited from sharing their feelings with friends or family.
