Clinical Trial Summary

An important cognitive bias in many emotional disorders, particularly obsessive-compulsive disorder (OCD), is thought-action fusion (TAF). TAF describes the bias to interpret the presence of unwanted mental intrusions as morally equivalent to acting on them (TAF-M), and/or increasing the likelihood of the feared consequence occurring to either oneself (TAF-LS) or others (TAF-LO). The present study is designed to test the feasibility of a single session computerized cognitive bias modification for interpretations (CBM-I) to reduce TAF among individuals who reported obsessional intrusions. Participants will be randomized to (a) the TAF-incongruent condition (TAF-INC), designed to decrease TAF linked to obsessional thoughts, to (b) the TAF-congruent condition (TAF-CON), designed to render TAF-like interpretation of obsessional thoughts unchallenged, or to (c) a Stress Management Psychoeducation (SMP) condition, designed to provide information about stress reduction, but not target TAF directly.

Description:

Individuals who display at least mild obsessional and TAF symptoms will be invited to the current study. Participants will be randomized to one of the three interpretation training conditions: an TAF-INC, TAF-CON, or SMP. Before and after the training, participants will complete some self-report questionnaires and clinician administered measures. The computerized training will provide statements intended to activate the mechanisms involved in thought-action-fusion (TAF), which will almost always produce a negative outcome interpretation. It is hypothesized that through TAF-INC participants will learn alternative, more neutral, ways of interpreting the thoughts and lower the subject's TAF. The TAF-CON condition will receive the same statements as TAF-INC, but TAF-CON is designed to leave the interpretation of the scenarios unchallenged. The study will also include another comparison condition, SMP, to test if TAF-INC outperforms not only TAF-CON, but also stress reduction techniques provided in empirically supported psychological treatment. The SMP training will be similar in procedure and structure to the other two conditions, but it will provide psychoeducation about stress and stress management techniques.

Recruitment information / eligibility

• Est. completion date: December 31, 2019

• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• UWM undergraduates who were at least 18 years old who (i) score of at least 1 [A Little (Distressed or Bothered)] on the OCI-R obsessing subscale, and (ii) at least one TAFS item scored 3 (Agree) or 4 (Agree Strongly) were be eligible to participate in the study. A score of 1 or higher on the obsessing subscale of the OCI-R indicates the presence of obsessional intrusions, and was used as a cutoff in previous research (Siwiec et al., 2017). A score of 3 or above on an item of the TAFS indicates the participant agrees with and holds some pronounced TAF bias.

Exclusion Criteria:

• Individuals whose primary language is not English will not be included in the study. Assessment and training programs are all written in English (we are not able to present a version in another language) - it is important for participants to understand subtlety of slightly varying vignettes in the training program.

Intervention

Other:
• Cognitive Bias Modification
There is support that CBM-I may work through the process of cognitive restructuring, and specifically, threat reappraisal. Threat appraisal is a tendency to overestimate the likelihood of harm (i.e., likelihood bias) and/or the negative consequences of anticipated harm (i.e., Clark & Beck, 2010), producing avoidance, thus interfering with effectively reappraising threat, thereby creating a vicious cycle (Beck et al., 1985; Clark & Beck, 2010). CBM-I procedures ensure that an interpretation bias is triggered by the ambiguous scenarios, and participants are then guided to solve the key word in accordance with a healthy response (Grey & Mathews, 2000). The observed effects of CBM-I may stem from active generation of benign or positive meanings in response to ambiguous situations, where threats were previously interpreted (Beadel et al., 2014).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Thought-Action Fusion Scale (TAFS) across Pre-training, Post-training, and 1-Month follow-up	The Thought-Action-Fusion Scale (TAFS; Shafran et al., 1996) is a 19-item measure which assesses the degree to which importance and responsibility is lent to a variety of intrusive and distressing thoughts containing moral and likelihood themes. The measure uses a 5-point scale ranging from 0 (Disagree Strongly), to 4 (Agree Strongly). There are no cutoff scores but higher TAFS scores are indicative of higher rates of TAF cognitions (Shafran et al., 1996). In student and community samples the three-scale model (TAF-M, TAF-LS, TAF-LO) has displayed moderate to strong association between the scales (r=.25 - .69; Abramowitz et al., 2003; Bailey et al., 2014; Coles, Mennin, & Heimberg, 2001; Rassin, Merkelbach et al., 2001).	Pre-training, post-training (same day as pre-training), 1-Month Follow-up
Secondary	Change in Primary Obsession Evaluation of TAF Scale (POETS) across Pre-training, Post-training, and 1-Month follow-up	The Primary Obsession Evaluation of TAF Scale (POETS; Siwiec et al., 2017) is designed to assess the participant's TAF emotional and cognitive reactions toward a specific (primary) obsessional intrusion. A study clinician helps identify their primary obsessive thought using the Y-BOCS Obsession Checklist. The POETS uses a 7-point scale from 0 (Not Distressing at All), to 6 (Extremely Distressing), and incorporates 3 domains (5 questions each): (1) General Emotional Reactions, (2) Moral TAF, and (3) Likelihood TAF. The general emotional reaction domain gauges discomfort with the presence of the thought, the moral domain gauges the moral implications of the thought, and the likelihood domain gauges the belief to which the event will occur because of the thought.	Pre-training, Post-training (same day as pre-training), 1-Month Follow-up
Secondary	Change in Revised Obsessional Intrusions Inventory - Distress (ROII-Distress) across Pre-training, Post-training, and 1-Month follow-up	The Revised Obsessional Intrusions Inventory - Distress (ROII-Distress) is a 52-item self-report measure, modified (Siwiec et al., 2017) from the original ROII (Purdon & Clark, 1993, 1994), to assess how distressing various intrusive thoughts, images, and impulses would be to the participant in the event of their intrusion. The measure uses a 7-point scale from 0 (Not Distressing), to 6 (Extremely Distressing). Unlike the original ROII, the ROII-Distress does not use a time frame as the obsessive thoughts, images, or impulses may not have occurred yet, but asks instead of distress if the thought were to occur. In consideration of heterogeneity in obsessional intrusions across individuals, we computed an idiographic distress index, consisting of the 10-highest endorsed ROII-Distress items for each participant at pre-training.
