DBT Diary Card

What is the DBT Diary Card?

The DBT diary card is the primary between-session self-monitoring tool in Dialectical Behavior Therapy, developed by Dr. Marsha M. Linehan. Clients complete it daily, recording their emotions, urges, target behaviors, and which DBT skills they practiced. The therapist reviews it at the start of each individual session to guide the treatment agenda and identify behavioral patterns.

Unlike scored assessments such as the PHQ-9 or GAD-7, the diary card does not produce a single composite score or severity classification. Instead, it provides a rich daily record that reveals patterns across time: which emotions precede target behaviors, which skills the client gravitates toward, and whether urges are decreasing with treatment.

The diary card is a core component of standard DBT. Without it, the therapist lacks the session-to-session behavioral data needed to conduct chain analyses, reinforce skills use, and prioritize the treatment hierarchy.

What Does the DBT Diary Card Track?

Emotions and Urges

Daily ratings on a 0-to-5 scale for key emotions such as sadness, anger, shame, anxiety, and joy, along with urges to self-harm or use substances. The numeric ratings let therapists spot escalation patterns before they reach crisis levels. When a client's urge-to-self-harm ratings creep from 2 to 4 over several days, that trajectory is visible on the diary card before it manifests as a behavioral incident.

Target Behaviors

Specific behaviors the client and therapist have collaboratively identified for monitoring. These typically include self-harm acts, substance use, and therapy-interfering behaviors (missing sessions, not completing homework, dissociating during sessions). Target behaviors are tracked as yes/no occurrences or frequency counts, creating a concrete behavioral record.

Skills Used

Checkboxes for skills practiced from all four DBT modules. Mindfulness skills include Wise Mind, Observe, Describe, Participate, Non-judgmental stance, One-mindful, and Effective. Distress Tolerance covers TIPP, STOP, Pros and Cons, Radical Acceptance, Distraction, and Self-soothe. Emotion Regulation includes ABC PLEASE, Opposite Action, Check the Facts, and Build Mastery. Interpersonal Effectiveness encompasses DEAR MAN, GIVE, FAST, and Validation techniques.

Medication Compliance

Simple yes/no tracking of whether prescribed medications were taken as directed each day.

Using the Diary Card in DBT Sessions

The diary card drives the session agenda in standard DBT through a strict priority hierarchy. The therapist reviews it at the start of each session to identify, in order: life-threatening behaviors since the last session, therapy-interfering behaviors, and quality-of-life-interfering behaviors. This hierarchy ensures the most critical clinical issues are addressed first, regardless of what the client might prefer to discuss.

Skills coaches also reference the diary card during between-session phone coaching calls. It provides context for what skills the client has already tried, what emotional states they are managing, and where coaching can be most effective.

Over weeks and months, the aggregated diary card data reveals treatment trends that would be invisible in a single session. Therapists can see whether overall skills use is increasing, which skill modules the client underutilizes, and whether the frequency and intensity of target behaviors are declining with treatment.

Paper vs. Digital Diary Cards

Traditional paper diary cards are a single-page weekly grid that clients fill out by hand and bring to each session. They are functional but have practical limitations: clients lose them, forget to bring them, or fill them out retroactively from memory right before the appointment. Handwriting legibility varies, and there is no way to aggregate data across weeks without manual effort.

Digital diary cards address these issues. Automatic daily reminders prompt completion in real time, reducing retrospective bias. Trend visualizations across weeks reveal patterns that are invisible on paper. The therapist has access to the data before the session starts, and aggregated reports can show emotion and urge trajectories, skills use frequency, and target behavior trends over the full course of treatment.

Some DBT programs prefer paper for philosophical reasons — the act of hand-writing can itself be a mindfulness practice. The clinical content should be identical regardless of format; the difference is in compliance rates, data accessibility, and trend visibility.
