 In a 12-week study, the study team is using a factorial design to test the effects of three intervention components: peer norming, default option, and sign effect. The intervention components are delivered via email messaging. To address the default bias, email messages reframe treatment use as an opt-out as opposed to opt-in behavior, thus nudging students to seek help. Students are able to check a box to opt out of receiving treatment linkage. Those who do not opt-out receive, without any purposeful action, continued assistance connecting to treatment. For the sign effect, messages emphasize the negative consequences of untreated EDs to engender urgency. Students in conditions with peer norming see how their levels of eating disorder symptoms results from widely-used, validated measures included in the baseline survey compare with average symptom levels among other undergraduates with data taken from national surveys previously conducted by the study team. Follow-up data is being collected at weeks 6 and 12. Intervention components are operationalized in electronic messages delivered over 12-weeks anticipated: January-May 2015.
