Brief Summary

Anxiety is the most common mental health problem in children and adolescents. This two-phased study will test the effects of an experimental computerized intervention aimed at reducing threat-based thinking (i.e., interpretation bias) in anxious youth. Participants in both the R61 (N=46) and R33 (N=72) trials will be youth ages 10 to 17 with a primary anxiety disorder (Separation, Social, Generalized). In the R61 trial, youth will be randomly assigned to receive 16 sessions over 4 weeks of either a personalized cognitive bias modification program for interpretation bias (CBM-I) or a computerized control condition (ICC). If CBM-I reduces interpretation bias significantly more than the ICC, the R33 trial will commence. In the R33, youth will be randomly assigned to either CBM-I or an equal amount of time in a cognitive restructuring intervention, which also aims to reduce threat-based thinking in anxiety. Please note that only the R61 phase of the trial has been completed and currently this record summary only reflects the R61 phase.

Outcome Measures

Primary Outcomes (3)

  • Change in Linguistic Interpretation Bias as Assessed by the Word-sentence Association Paradigm for Youth (WSAP-Y)

    The WSAP-Y is a computerized assessment of interpretation bias in which youth indicate whether word-sentence pairings are related. This measure provides information about the degree to which youth evidence interpretation bias, as well as a behavioral (reaction time) index for bias endorsement. For the primary outcome of percent threat interpretations endorsed, the possible range is 0 (zero) to 100%. Higher percentage indicates more threat interpretation bias (i.e., the youth endorsed a higher proportion of threat words as related to amiguous sentences); lower scores indicate lower threat interpretation bias. Greater decrease in the percent of threat interpretations endorsed and lower absolute scores indicate "better" outcome (i.e., more reduction in threat interpretation bias; less interpretation bias overall).

    6 weeks; post-intervention time point

  • Change in Visual Interpretation Bias as Assessed by the Ambiguous Faces Task

    Youth view faces portraying neutral expressions or subtle emotional expressions (i.e., morphed faces ranging in intensity of emotional valence). Youth categorization of faces as neutral or threatening provides their sensitivity and bias for reporting presence of threat. The criterion mean value in outcomes below reflects a score from -1 to 1, with higher negative numbers reflecting greater bias toward angry faces, and higher positive values approaching one reflecting a bias toward happy faces. Theoretically, higher positive values indicate "better" outcome such that youth have more positive bias toward facial stimuli. H

    6 weeks; post-intervention time point

  • Change in Self-reported Interpretation Bias as Measured by the Children's Automatic Thoughts Scale (CATS)

    The Children's Automatic Thoughts Scale is a youth self-report questionnaire which assesses presence and frequency of a variety of anxious thoughts from domains of: physical threat, social threat, personal failure, and anxious hostility. Total scores range from 0 to 160, with higher scores indicating more threat interpretation bias. Higher scores indicate "worse" outcome, or that youth self-report that they have more threatening thoughts and/or threatening thoughts at higher frequency; lower scores indicate "better" outcome or that youth self-report fewer threatening thoughts and/or threatening thoughts at lower frequency.

Study Arms (2)

Cognitive Bias Modification for Interpretations (CBM-I)

EXPERIMENTAL

Computerized 16-session intervention aimed at reducing interpretation bias. In this study, CBM-I is personalized to youth anxiety symptoms. During CBM-I sessions, youth indicate whether word-sentence pairs are related, and are provided with feedback aimed to reduce bias.

Other: Cognitive Bias Modification for Interpretations (CBM-I)

Interpretation Control Condition (ICC)

PLACEBO COMPARATOR

Computerized 16-session intervention that is not believed to significantly modify bias. In this study, youth see stimuli personalized to their anxiety symptoms. During ICC sessions, youth see word-sentence pairs and are required to indicate whether word and sentence are related, but are not provided with feedback that aims to "train" a reduction in interpretation bias.

Other: Interpretation Control Condition (ICC)

Interventions

Computerized intervention in which youth see word-sentence pairs personalized to their anxiety symptoms, and indicate whether these are related. Youth receive feedback aimed to reduce interpretation bias.

Also known as: Interpretation bias modification, Interpretation training
Cognitive Bias Modification for Interpretations (CBM-I)

Computerized control condition in which youth see word-sentence pairs personalized to their anxiety symptoms. Youth indicate whether these are related, but are not provided with feedback that aims to "train" a reduction in interpretation bias.

Interpretation Control Condition (ICC)

Eligibility Criteria

Age10 Years - 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • youth aged 10 to 17
  • diagnosed at study baseline with a primary "big three" anxiety disorder (Separation, Social, Generalized)
  • standard score greater than or equal to 85 on the Wide Range Achievement Test - Word Reading Subtest (to ensure ability to read stimuli during interpretation bias assessment and CBM-I/ICC), and estimated IQ standard score of at least 80 on the Wechsler Abbreviated Scale of Intelligence
  • youth and consenting parent/legal guardian speak sufficient English to complete consent/assent and study procedures
  • no concurrent psychosocial services during study participation to reduce likelihood that other interventions are responsible for change in primary or secondary outcomes
  • no psychotropic medications with no plans to start medications during study, or six weeks stable on SSRI or psychostimulant medication and dose with no plans to change medication/dose during study

You may not qualify if:

  • severe anxiety indicting that youth requires higher level of care (e.g., intensive treatment such as psychiatric hospitalization), significant diagnostic comorbidity (e.g., presence of psychosis or significant mood disorder), or another primary diagnosis that warrants alternate intervention
  • significant uncorrected vision impairment (e.g., uncorrected blindness) that precludes participation in CBM-I/ICC
  • safety concerns due to recent or acute suicidality with plan, intent, and/or attempt that warrants alternate intervention

Limitations and Caveats

The trial was funded in January 2020, and recruitment scheduled to begin in April 2020. COVID shutdowns in March 2020 led to delays in initiating recruitment, continued delays in recruitment, and COVID-related illnesses that led to enrolled participants rescheduling their in-person study visits beyond the initially scheduled 6 weeks of study participation for the first 2.5 years of recruitment. Our analytic method allows for controlling for number of days in study to address this.
