Mobile Interpretation Bias Modification Clinical Trial

Summary

The Mobile-Interpretation Bias Modification clinical trial aims to examine the efficacy of a brief mobile phone delivered interpretation bias modification to reduce anxiety sensitivity cognitive concerns and suicidal ideation in National Guard Personnel. The investigators propose a randomized controlled trial testing the efficacy, acceptability, and usability of M-IBM with a sample of 114 National Guardsmen with current suicidal ideation and elevated anxiety sensitivity cognitive concerns. Participants will complete assessments, receive assistance on installing M- IBM on their phone, complete an M-IBM intervention session, and complete post-intervention assessments. Baseline measures of psychopathology, and usability/acceptability of M-IBM will be obtained during the initial session. In addition, 1-month, and 3-month follow-ups would be scheduled to examine changes in psychopathology. The investigators hypothesize that those randomized to M-IBM will experience reductions in anxiety sensitivity cognitive concerns, suicidal ideation. In addition participants will find M-IBM acceptable and easy to use.

Conditions

• Anxiety Sensitivity
• Suicidal Ideation

Interventions

BEHAVIORAL

M-IBM

In this paradigm, an ambiguous word or two-word phrase related to ASCC is followed by a sentence that resolves the word-sentence meaning as threatening or benign. For example, participants are presented with an ambiguous word or two-word phrase for 1 second. On half the trials the combination of the word/phrase and sentence creates a benign meaning (as in the previous example). On the other half of trials this combination creates an anxious-threat meaning Participants are required to judge the relatedness of the word/phrase and the sentence. Participants are given feedback during training such that judging the anxious-threat combinations to be "unrelated" and the benign combinations as being "related" would produce a "correct" response. In contrast, if participants produce an "incorrect" response they see "incorrect".

BEHAVIORAL

Control-IBM

Placebo IBM where sentences are not related to anxious threat meaning of cue word.
