Prompts to increase attendance in a community mental-health center.

The team called patients one to three days before their mental-health appointment. Each call lasted about thirty seconds. Staff read the same short script reminding people of the date and time.

They used an alternating-treatments design. Some weeks they made calls, other weeks they did not. More than one thousand appointments were tracked this way.

No-show rates dropped from about thirty percent to about twelve percent when calls were made. The clinic saved money after only six kept visits paid for the whole calling program.

The reminder worked for adults with many different diagnoses. The effect showed up right away and stayed strong across the whole study.

The result lines up with three later sign-prompt studies. Cooper et al. (1990) used posters to double condom pickups in bars. Sievert et al. (1988) used counter signs to boost salad sales. van Schrojenstein Lantman-de Valk et al. (2006) placed small prompts at cash registers and lifted food-bank donations. All show that a cheap, well-timed cue changes community health behavior.

Johnson et al. (2024) took the same idea into schools. They swapped the phone call for a weekly email prompt and raised preschool teachers’ correct instruction delivery. Gerald et al. (2019) used vibrating timer prompts to push staff data recording to ninety percent. Together these papers stretch the 1976 reminder trick from patient attendance to staff performance.

Burgio et al. (1986) paired a verbal prompt with praise and doubled nursing-home residents’ walking distance. Their method is cousin to the phone reminder: a brief antecedent cue plus a quick positive consequence. Both studies kept procedures simple and costs tiny.

You can copy this call script today. One aide can phone every client the day before session. Expect no-shows to fall by half. The calls pay for themselves after six kept appointments. Use the same logic with staff: a short email, text, or timer buzz can keep treatment fidelity high. Prompts are cheap, fast, and they work across settings, ages, and behaviors.
