Improving Attentional and Cognitive Control in the Psychological Treatment of Intrusive Thoughts

The current study will examine whether enhancing attention regulation skills in a transdiagnostic intervention for repetitive negative thinking (RNT) will significantly improve the target of attentional/cognitive control. Phase 1 is an open pilot trial in which participants will be assigned to eight 60 minute sessions (over 8 weeks) of Emotion Regulation Therapy-Attention Regulation (AR-ERT). In Phase 2, participants will be randomly assigned (like the flip of a coin) to receive eight 60 minute sessions (over 8 weeks) of either: AR-ERT or Supportive Psychotherapy (SPT). The investigators will use a multi-method approach to measure attentional/cognitive control: (a) behavioral (i.e., eye tracking fixations and reaction time), (b) electrophysiological (i.e., event related potentials), and (c) self-report (i.e., perceived ability to shift and focus attention). They also will examine early signs of treatment efficacy of AR-ERT and SPT and target validation (i.e., whether changes in attentional/cognitive control correlate with changes in RNT and associated symptoms). Participants will receive assessments of these target and outcome measures at baseline (week 0), mid-treatment (week 4), post-treatment (week 8), and 3-month follow-up (week 20 - Phase 2 only). While most of these procedures are conducted virtually (e.g., therapy sessions), some (e.g., eye tracking and electrophysiological assessments) will be performed in-person. Findings could help identify a cross-cutting target that can be engaged to optimize treatment response for individuals with elevated RNT.
