简要总结
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.
详细描述
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.

入选标准
- •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.
排除标准
- •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.
研究组 & 干预措施
TAF Incongruent (TAF-INC)
Active condition (TAF-INC) cognitive bias modification for interpretations (CBM-I), incorporates an obsessional thought meant to elicit either moral or likelihood TAF, followed by a sentence incongruent to TAF bias and meant to reduce the impact of the previous statement. Before moving on, participants must fill-in and correctly solve a key word important in the interpretation of the sentence. Participants then must correctly solve a short yes/no comprehension question to ensure understanding of the scenario.
干预措施: Cognitive Bias Modification (Other)
TAF Congruent (TAF-CON)
Maintenance/Control condition (TAF-CON) CBM-I, differs in that participants are provided with a sentence congruent with TAF bias. Again, participants were only able to move on when they correctly solved the key word and the accompanying yes/no comprehension question.
干预措施: Cognitive Bias Modification (Other)
Stress Management Psychoeducation
In the stress management psychoeducation (SMP) psychoeducation about stress and stress management are provided, similar in length to the obsessional thought and interpretations presented in the TAF-INC and TAF-CON. Like the other conditions there is a key word to solve, and participants were only able to move on when they correctly solved the key word and the accompanying yes/no comprehension question.

结局指标
主要结局
Change in Thought-Action Fusion Scale (TAFS) across Pre-training, Post-training, and 1-Month follow-up
时间窗: Pre-training, post-training (same day as pre-training), 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).
