Using Diary Cards in DBT: A Digital Approach
The diary card is one of the most important tools in dialectical behavior therapy. Clients fill it out daily, tracking emotions, urges, skills used, and target behaviors. Therapists review it at the start of each session to set the agenda and identify patterns.
In theory, it's elegant. In practice, paper diary cards are a mess.
The paper diary card problem
Clients forget to bring them. They lose them. They fill them out retroactively in the waiting room (which defeats the entire purpose of daily tracking). The data they contain is trapped on a single piece of paper that can't be aggregated, analyzed, or compared over time.
Even when a client diligently fills out their paper diary card every day and brings it to session, the therapist reviews it visually, tries to spot patterns across seven days of handwritten entries, and then moves on. There's no longitudinal view. Last month's diary cards are in a file somewhere, disconnected from this week's.
For a modality that's fundamentally about identifying patterns, tracking change, and reinforcing skill use, this is a significant limitation.
There's also a supervision issue. In a standard DBT consultation team, therapists discuss cases and review treatment progress. But if the diary card data exists only on paper forms scattered across client files, it's nearly impossible to present longitudinal patterns to your consultation team. You're reduced to summarizing from memory, which is exactly the kind of subjective clinical judgment that DBT was designed to augment with data.
What digital diary cards solve
Compliance. A push notification on the client's phone at 8 PM saying "Time for your diary card check-in" gets completed at dramatically higher rates than a paper form sitting in a purse or backpack. The client's phone is in their hand. The diary card takes 2-3 minutes. The reminder reduces the biggest barrier to diary card compliance: forgetting.
Accuracy. Same-day digital entries reflect what actually happened. Retrospective paper entries filled out three days later reflect what the client remembers happened, filtered through whatever mood they're in when they fill it out. Digital entries with timestamps provide more accurate data.
Longitudinal tracking. When diary card entries live in a database, they can be charted over time. You can see a client's urge intensity trending down over six weeks. You can see that skill use increases after specific sessions. You can identify that emotional dysregulation spikes consistently on certain days of the week. Paper can't do any of this.
Session efficiency. Instead of spending the first 10 minutes of a DBT session manually reviewing a paper diary card, you pull up a chart that shows the week's entries at a glance. Emotions, urges, target behaviors, and skills used — all visualized. You identify what needs attention in seconds instead of minutes, and you spend the saved time on actual therapy.
What a digital diary card should track
The standard Linehan diary card tracks several categories. A digital version should include all of them, formatted for quick daily completion:

Emotions. Primary emotions experienced that day, with intensity ratings (0-5 or 0-10). Digital sliders or tap-to-rate interfaces are faster than handwriting numbers.
Urges. Self-harm urges, substance use urges, or other target behavior urges, with intensity ratings. These are the highest-priority items for session agenda-setting.
Target behaviors. Did the target behavior actually occur? Binary (yes/no) tracking per day. If yes, the context matters, but the binary tracking provides the longitudinal data.
Skills used. Which DBT skills did the client practice? A checklist format works well digitally — the client taps the skills they used rather than writing them out. This tracks skill generalization over time.
Medication compliance. If applicable, tracking whether prescribed medications were taken.
Overall misery rating. A single daily 0-10 rating that captures general distress level. This is the simplest longitudinal measure and often the most revealing over time.
The couples diary card comparison
For therapists doing DBT-informed couples work, digital diary cards enable something paper can't: side-by-side daily comparison between partners.
When both partners complete diary cards independently, aligning their entries by date reveals relational dynamics that neither partner's individual data shows. On the same day, one partner reports high urges and low skill use while the other reports low distress — what happened in the interaction between them?
This comparison only works digitally. Paper diary cards would need to be manually aligned, which no therapist has time for.
Implementation in practice
Introduce the digital diary card the same way you'd introduce the paper version: as a collaboration tool that helps both of you track what's happening between sessions.
"I'm going to set you up with a daily check-in on your phone. It's basically the diary card we've been using, but digital — so you won't forget to bring it, and I can see your trends over time instead of just this week."
Most clients prefer the digital version once they try it. It's faster, it's on their phone, and the reminder means they actually do it consistently.
Set the reminder time collaboratively. Some clients prefer end-of-day (reflecting on the whole day). Some prefer multiple check-ins. For urge tracking specifically, a midday and evening prompt often captures more accurate data than a single end-of-day recall.
Reading the data over time
After 2-3 weeks of consistent digital diary card entries, patterns start to emerge. This is where digital tracking transforms from a compliance tool into a clinical tool.
Look for: emotion intensity trends (are they stabilizing?), urge frequency and intensity (declining, stable, or increasing?), skill use patterns (which skills is the client actually using? which ones never get checked?), and day-of-week patterns (does distress spike on specific days?).
These patterns inform treatment planning directly. If a client consistently reports high distress on Sundays, that's a discussion about what Sundays involve. If they're using distress tolerance skills but never emotion regulation skills, that suggests where to focus skills training.
The trend data also creates powerful moments in therapy. Showing a client that their average urge intensity has dropped from 7.2 to 4.1 over eight weeks is more motivating than saying "it seems like things are getting better." The concreteness matters, especially for clients with BPD, who often have difficulty recognizing their own progress due to emotional volatility in the moment. A bad day can make a client feel like nothing has changed — but the data tells a different story.
Theracharts includes diary card tracking as part of its assessment and form system, with daily push notification reminders through the client portal, emotion and urge sliders, skill use checklists, and longitudinal trend charts. For couples, diary entries align by date for side-by-side comparison. The data flows directly into the session — no paper required. Clients can also use the free DBT Skills Finder between sessions — a quick flowchart that helps them pick a skill for what they're feeling in the moment, with no account required.
