NCT02615717

Brief Summary

Threat-related attentional biases have been identified as a possible precursor to the onset and maintenance of posttraumatic stress disorder (PTSD). As a result, protocols such as Attention Bias Modification (ABM) have been developed and utilized to treat these attentional biases in adults diagnosed with PTSD. However, to-date, ABM protocols have not been examined for use specifically among victims of sexual assaults. Participants are 20 undergraduate women enrolled in a Midwest university. The efficacy of ABM in this population will be assessed, as will the relationship between ABM and PTSD symptom clusters and outcome variables such as anxiety and depression scores.

Outcome Measures

Primary Outcomes (1)

  • Clinician-Administered PTSD Scale (CAPS-5)

    Assesses symptoms and severity of Posttraumatic Stress Disorder Range: 0-80; total score utilized. Higher values indicate higher severity Subscales are summed to create a total score; subscales made up of different facets of PTSD.

    within three days

Secondary Outcomes (3)

  • PTSD Checklist (PCL-5)

    within three days

  • Patient Health Questionnaire (PHQ-9)

    within three days

  • Beck Anxiety Inventory (BAI)

Study Arms (2)

Attentional Bias Modification

EXPERIMENTAL

In the ABM treatment condition, participants will have four 20-minute in-lab treatment conditions across two weeks. Within these Attention Bias Modification sessions, participants will be presented with a fixation cross for 500 ms. The fixation cross will then be replaced with a word pair consisting of either a threat/neutral pair or a neutral/neutral word for 500 ms, followed by a probe in the location of one of the two words (80% threat/neutral pairs, 20% neutral/neutral pairs; the target will always appear in the location of the neutral word).

Behavioral: Attention Bias Modification

Attentional Control Condition

ACTIVE COMPARATOR

Participants will have four 20-minute in-lab treatment conditions across two weeks. Within the Attention Bias Modification control sessions, participants will be presented with a fixation cross for 500 ms. The fixation cross will then be replaced with a word pair consisting of either a threat/neutral pair or a neutral/neutral word for 500 ms, followed by a probe in the location of one of the two words (80% threat/neutral pairs, 20% neutral/neutral pairs; the target appears in the location of the neutral word in 50% of the trials. Complete Stroop and 3-back task, etc.
