Brief Summary:
The goal of the project is to test whether a single-session intervention teaching incremental theories of personality, or the belief that one's personality is malleable, can strengthen recovery from social stress and reduce the development of anxiety and depression during early adolescence. Results may suggest a scalable, cost-effective approach to improving youths' coping capacities and preventing adverse mental health outcomes over time.

Detailed Description:
Efforts to prevent and reduce mental health problems in youths have advanced greatly in recent years. However, these advances have not reduced rates of youth mental illness on a large scale. Thus, a great need exists for novel, scalable, and low-cost approaches to reducing mental health problems in youth. Ideally, such approaches would be mechanism-targeted: that is, they would act on specific developmental processes that underlie psychological disorders. The proposed research aims to address this need by testing whether a single-session intervention teaching incremental theories of personality, or the belief that one's personality is malleable—as opposed to entity theories of personality, or the belief that one's personality is fixed and unchangeable—can strengthen recovery from social stress and prevent the development of anxiety and depression during early adolescence. Compared to incremental theories, entity theories of personal traits have demonstrated cross-sectional and prospective relations with greater anxiety and depression in youths. Further, a single-session incremental personality theories intervention reduced the development of depressive symptoms in a community sample of adolescents, supporting these theories as powerful intervention and/or prevention targets, even when taught in a brief format. Specifically, this project has two aims. Aim 1 is to evaluate the effect of the implicit theories intervention on two candidate mechanisms of action, or targets, identified by prior research: arousal (measured via physiological reactivity following social stress) and loss (here, perceived loss of behavioral control) in youths 12-15 years of age. Following a lab-based social stress induction, I hypothesize that participants receiving the intervention will recover from stress more rapidly, as indicated by measures of arousal (heart rate variability; electrodermal activity levels) and self-reported loss (increased self-reported perceived control) compared to participants who do not receive the intervention. Aim 2 is to evaluate the effects of the single-session incremental theories intervention on anxiety and depression over a nine-month follow-up period. I will test whether the intervention, compared to a control protocol, reduces symptoms of anxiety an depression the development of anxiety and depression; I will also assess whether this change is a direct result of shifts in the two aforementioned targets (arousal; loss). I predict more positive trajectories in anxiety and depression for youth receiving the intervention, relative to those who do not receive the intervention, across nine months. I will also test whether these trajectories are mediated by changes in the targets described in Aim 1. Finally, regardless of outcomes for Aims 1 and 2, baseline, postintervention, and 9-month measures will be used to map links among implicit theories, interventions targeting those theories, social stress recovery, and youth anxiety and depression over time. Findings may suggest a cost-effective, scalable intervention that improves youth resiliency and mental health.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 96 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Participants (N=96), ages 12-15 will be randomized to receive one of two a 30-minute, computer-based programs: (1) a 'growth mindset' program, teaching that personal traits and characteristics are malleable; or (2) a control program, designed to mimic 'supportive therapy,' teaching the value of sharing one's feelings with close others.

Arm Intervention/treatment
Experimental: Implicit Theories of Personality Program
This program is self-administered, computer-based, and 30 minutes in length. Content is designed to maximize relevance for youths with internalizing distress. The program includes 5 elements: 1. An introduction the concept of neuroplasticity; 2. Testimonials from older youths describing beliefs that people's traits are malleable, given the brain's capacity for change; 3. Further vignettes by older youths describing times when they used "growth mindsets" to cope with peer rejection, hopelessness, and feared embarrassment; 4. A worksheet describing strategies for applying these principles to participants' lives; 5. An exercise wherein participants write notes to younger children, using newly-gleaned information about the malleability of personal traits to help them to cope with setbacks
Other: Implicit Theories of Personality Program
This 30-minute, self-administered computer program teaches youths that personality is malleable, as opposed to fixed, due to the human brain's constant potential for change and growth (i.e., neuroplasticity).
Other Name: Growth Mindset of Personality Program

Active Comparator: Control Program
The Control Program is a computer-based session of supportive therapy (ST), designed to encourage youths to identify and express feelings. ST does not teach specific skills or beliefs and has been shown to be less effective than cognitive-behavioral interventions in reducing youth internalizing distress. Here, ST was designed to control for nonspecific intervention elements (eg. completing an interactive computer program) and to encourage youths to share emotions with others. ST included the same number of reading/writing activities as the experimental program and took the same amount of time (30 mins.) to complete.
Other: Control Program
This 30-minute, self-administered computer program was designed to control for nonspecific aspects of completing a series of computer-based activities in the context of the present study. It was also designed to mimic 'supportive therapy' that youths might receive in usual care settings, stressing the importance of sharing one's feelings with close others.
Other Name: Supportive Therapy (ST) Program
