The current study is based on analyses conducted from a previous study looking at the correlation between response inhibition (RI) and impulsivity with obsessive compulsion disorder (OCD). OCD is characterized by recurring and/or unwanted thoughts or sensations that may lead to compulsive behavior (American Psychiatric Association (APA), 2013). Although compulsive behaviors are premeditated while impulsive behaviors are not, literature has shown that impulsivity may predict OCD symptoms (Potenzia et al., 2009). The goal of our study was to evaluate which features of impulsivity (i.e., motor, non-planning, attention) were associated with OCD, after controlling for emotional symptoms like depression, anxiety, and stress (Carter et al., 2005).  We hypothesized that individuals with OCD would have significantly elevated impulsivity symptoms across all three domains (i.e., attention, motor, and non-planning) after controlling for emotional symptoms. The sample included 701 individuals from the University of Wisconsin-Milwaukee. To evaluate emotional and impulsivity symptoms, participants completed the Depression, Anxiety, and Stress Scale (DASS-21) and the Barratt Impulsiveness Scale (BIS), respectively.  To determine the influence of impulsivity on OC-severity the Obsessive-Compulsive Inventory Revised (OCIR) was used, a two-step hierarchical linear regression was run, where Step 1 included DASS-21, and Step 2 included BIS factors. The findings revealed that the non-planning factor was a significant predictor of OCIR symptoms over emotional symptoms (R2 Δ = 34.1, p=0.004). In contrast, neither the attention nor motor factor significantly predicted influence emotional symptoms (R2 Δ=0.000, p= 0.974, p= 0.981). The findings suggest that the individuals who are higher in symptoms of non-planning such as finding enjoyment of challenging tasks, demonstrate higher OC-symptoms.

  1. Great job on the poster and great job on participating in the symposium!
    Poster looks great – layout, flow and content. Voice over slide was too flat. I suggest you emphasize certain parts and change tone when needed to keep the attention of your audience.
    Nice graph. Please remember to add a sentence prior to showing your graph. You need to introduce your graph first.
    Missing acknowledgments section.
    I liked the statistical analysis.

  2. Thank you team, this is an interesting finding, and can be useful to those working with individuals struggling with OCD.
    Good work, and I’m sorry the pandemic prevented you from presenting in person.

    Take care, and Congratulations!

  3. Interesting topic! I was able to clearly understand the objective, hypothesis, and discussion (even though I have very limited knowledge about the topic) as they were described. I felt the poster had good visual flow. I could read through the concise bullet points without feeling overwhelmed.
