ERP Exposure Homework Worksheet: Tracking SUDS During Exposure Practice

This worksheet guides clients through a high-resolution monitoring protocol essential for effective Exposure and Response Prevention (ERP). The layout provides a structured 60-minute log, requiring clients to document their Subjective Units of Distress (SUDS) in 10-minute increments from the beginning of the task to the conclusion. A critical clinical component of this tool is its focus on “within-session habituation”—the biological process where anxiety naturally peaks and then declines when an individual remains in the presence of a trigger without performing compulsions. By requiring ratings at 10, 20, and 30-minute intervals, the worksheet helps clients move from a state of “escape-oriented” thinking to one of “curious observation.”

The structured layout is designed to facilitate “Inhibitory Learning” by providing immediate visual evidence of the anxiety arc. By documenting SUDS ratings (0–10) over a full hour of practice, the worksheet serves as an empirical record of the client’s growing distress tolerance. This process is essential for helping clients recognize that while anxiety is uncomfortable, it is not a permanent state and will inevitably dissipate if safety behaviors are withheld. By externalizing the time-limited nature of distress, clients gain the clinical self-efficacy necessary to stay “in the heat” of an exposure until new learning occurs.

How This Worksheet Can Be Used

Tracking Habituation Cycles:
Therapists use the worksheet to determine if a client is staying in an exposure long enough for learning to happen. If SUDS ratings drop significantly between the 20 and 50-minute marks, the clinician can confirm that habituation is occurring and reinforce the client’s commitment.

Identifying “Compulsion Interference”:
This tool is highly effective for identifying subtle safety behaviors. If a client’s SUDS ratings remain at a 10 for the entire 60 minutes without any decline, the clinician can use the “Comments” section to investigate if the client was performing mental rituals or neutralizing thoughts during the practice.

Treatment Adjustment:
Clients use the worksheet to provide “raw data” for session reviews. By analyzing the “difficulty comments” alongside the numerical data, the therapist can decide if the current task is appropriately challenging or if the exposure hierarchy needs to be adjusted.

Benefits of the ERP Exposure Homework Worksheet

• Provides a granular, 10-minute interval structure for precise distress monitoring.
• Supports the “Inhibitory Learning” model by visualizing the natural decline of anxiety.
• Identifies the “Peak Distress” point, helping clients anticipate and prepare for high-arousal moments.
• Encourages “Behavioral Persistence” by requiring a full 60-minute evaluation period.
• Builds clinical self-efficacy by proving that distress is time-limited and tolerable.
• Reduces “Recall Bias” by prompting the client to record feelings in real-time rather than after the fact.

Integrating This Tool into Clinical Work

Integrating the ERP Exposure Homework Worksheet is most effective when clinicians emphasize that “the drop is the goal.” Clinicians should guide clients to set an alarm for every 10 minutes during their homework to ensure the SUDS ratings are recorded accurately. In the “Comments” section, the clinician should help the client differentiate between “physical difficulty” (e.g., heart racing) and “mental difficulty” (e.g., the urge to wash). It is vital to validate that the “Beginning” score is often the most intimidating; by consistently reviewing these logs, the clinician reinforces the idea that the client has the power to outlast their anxiety, leading to a more autonomous and resilient recovery.
