Details and patient eligibility

About

This investigation examines the efficacy of a brief, one-session computerized interpretation bias modification paradigm (CBM-I) in the reduction of intolerance of uncertainty. Intolerance of uncertainty is a risk factor for the development and maintenance of various forms of psychopathology.

Enrollment: 79 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Elevated IU interpretation bias at pre-intervention.

Exclusion criteria

• None.

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

79 participants in 2 patient groups

Active IU CBM-I

Experimental group

Description:

This paradigm was designed to train individuals to endorse benign interpretations of ambiguous information and reject negative/threatening interpretations of ambiguous information. Participant's baseline interpretation bias was measured at baseline. Participants then underwent two training phases in which their responses were either reinforced (i.e., they were told they were correct) or punished (i.e., they were told that they were incorrect). Interpretation bias was measured again at post-training.

Treatment:

Behavioral: Active IU CBM-I

Control CBM-I

Sham Comparator group

Description:

This paradigm was identical to the active condition except that the word/sentence pairings used were not relevant to IU and/or anxiety.

Treatment:

Behavioral: Control CBM-I
