Study Arms (2)
Interpretation Bias Modification (IBM)
EXPERIMENTALTreatment consists of eight brief sessions. In Task 1, participants read unique scenarios ("You notice someone pointing in your direction"). A sentence meant to resolve the ambiguity will appear ("This person thinks they reco\_nize you"). After filling in the missing letter, the interpretation is reinforced by requiring the participants to correctly answer "yes" or "no" to a comprehension question ("Is this person mocking you?"). In Task 2, participants are shown a word denoting a threatening ("mocking") or benign ("cheerful") interpretation. Participants are presented with an ambiguous scenario ("You hear people at a nearby table laughing") and asked to denote whether the word and the sentence are related. Participants will receive positive or negative feedback based on their response.
Progressive Muscle Relaxation (PMR)
ACTIVE COMPARATORParticipants will receive eight brief sessions of PMR. They will listen to a PMR script (Kassinove \& Tafrate, 2002). Participants will be asked to make sure they are sitting comfortably, close their eyes, and systematically tense and release 10 different muscle groups.
Interventions
Eight 10-25 minute sessions of interpretation modification to reduce negative interpretation biases related to appearance.
Eight 15-minute sessions of progressive muscle relaxation (PMR).
