Abstract Background Past research links hoarding disorder (HD) to indecisiveness and difficulty with decision-making. However, it remains unclear what contributes to difficulty making decisions in HD. Decision-making research suggests that some individuals have a maximizing decision-making style (seeking the best option through an exhaustive search of all existing alternatives) while others “satisfice” (choosing options that are satisfactory even without seeing all options). Past work has linked...

Abstract Internet-based cognitive-behavioral therapy (ICBT) with therapist support shows promise as a treatment for obsessive-compulsive disorder (OCD). Yet, not all patients respond to ICBT. It is therefore important to identify predictors of ICBT outcomes to determine who is likely to benefit. Relative to the large literature on predictors of outcomes for in person CBT for OCD, very few studies have investigated ICBT predictors. Therefore, we analyzed predictors of outcome in an open trial (n ...

Abstract Cross-sectional studies have reported failures in goal-directed planning in obsessive-compulsive disorder (OCD). It remains unclear whether these deficits confer vulnerability to developing OCD, or are a consequence of symptoms. The present study examined goal-directed learning before and after cognitive behavioral therapy (CBT), using treatment as a tool to reduce symptoms. Eighteen adult OCD patients undergoing 17 sessions of CBT completed an established task of model-based (i.e., goa...

Abstract In recent years, with scientific advances and growing understanding of neurobiological processes, biomedical explanations of psychiatric disorders, including obsessive-compulsive disorder (OCD), have become more prominent in research and in clinical care. Patient perceptions of biomedical models of OCD have been understudied, particularly in how they relate to patients’ beliefs about prognosis and treatment expectancy. The current study measured self-identified OCD patients’ (N = 130) c...

Abtract Introduction A single subanesthetic intravenous (IV) dose of ketamine leads to rapid anti-obsessional effects in obsessive-compulsive disorder (OCD) patients with near-constant intrusive obsessions, but these effects usually do not persist. We tested whether a brief course of exposure-based cognitive behavioral therapy (CBT) could extend ketamine’s effects in a two week pilot open trial and if this effect was maintained (without additional treatment) two weeks later. Our rationale was: 1...

BACKGROUND: Many individuals with obsessive-compulsive disorder (OCD) display behavioral avoidance related to their obsessional thoughts and compulsive behaviors. However, how these avoidance behaviors impact treatment outcomes with exposure and response prevention (EX/RP) remains unclear. We examined pretreatment avoidance behaviors as predictors of EX/RP outcomes. METHODS: Data came from a randomized controlled trial of augmentation strategies for inadequate response to serotonin reuptake inhi...
