Adolescents will review five research protocols related to a fictitious disease ('meditis') and respond to a question about their willingness to participate in each research study (e.g., If you had meditis, would you agree to enroll in this study?; 1 = Definitely not to 7 = Definitely yes). Responses will be averaged across the five protocols and the minimum scale score is 1 and the maximum scale score is 7. Higher scores indicate greater willingness to participate in the research studies.

Adolescents will be asked to respond to 8 questions related to their perceptions of their relationship quality and communication with their parents (e.g., My parent gives me good advice; 1 = Strongly disagree; 2 = Disagree; 3 = Agree; 4 = Strongly agree). Responses will be averaged and the minimum scale score is 1 and the maximum scale score is 4. Higher scores indicate more positive perceptions of relationship quality.

Parents will be asked to respond to 6 questions that assess their positive attitudes about clinical trials (e.g., How do you feel about teens participating in clinical trials?; 1=Not good at all; 2=Not very good; 3=Not sure; 4=Good; 5=Very good). Responses will be averaged and the minimum scale score is 1 and the maximum scale score is 5. Higher scores indicate more positive attitudes toward clinical trials.

Parents will be asked to respond to 5 questions about their beliefs about pediatric clinical research (e.g., I believe that clinical trials can help teens; 1=Strongly Disagree; 2=Disagree; 3=Unsure; 4=Agree; 5=Strongly Agree). Responses will be averaged and the minimum scale score is 1 and the maximum scale score is 5. Higher scores indicate more positive beliefs about clinical trials.

Parents will be asked to respond to one question about the likelihood of allowing their child to participate in a clinical trial (i.e., If your child were asked to be in a clinical trial, how likely would you be to let them participate?; 1 = Not likely at all; 2 = Not very likely; 3 = Not sure; 4 = Likely; 5 = Very likely). Responses will be averaged and the minimum scale score is 1 and the maximum scale score is 5. Higher scores indicate greater likelihood of allowing child to participate in a clinical trial.

Parents will be asked to respond to 16 questions regarding their perceptions of the quality of communication with their adolescent (If my child were in trouble, she/he could tell me; 1 = Strongly Disagree, 2 = Disagree; 3 = Agree; 4 = Strongly Agree). Responses will be averaged and the minimum scale score is 1 and the maximum scale score is 4. Higher scores indicate more positive perceptions of relationship quality.

Participants will not have access to the educational website between the pre-test and post-test assessments. After completing the post-test questionnaires, participants in the wait-list control group will receive access to the intervention (DigiKnowIt News: Teen).
