Improving medication adherence by using practitioner nonverbal techniques: a field experiment on the effect of touch

Area of Science:

• Health Psychology
• Behavioral Medicine

Background:

• The influence of touch on compliance is well-documented in social psychology.
• Its application and impact within healthcare settings require further investigation.

Purpose of the Study:

• To evaluate the effect of a brief tactile intervention by general practitioners on patient medication adherence.
• To assess patient perceptions of practitioner concern and competence following the tactile intervention.

Main Methods:

• Six general practitioners were instructed to either touch or not touch patients on the forearm for 1-2 seconds.
• Patients with mild pharyngitis were verbally prompted to adhere to antibiotic prescriptions.
• Medication adherence and patient perceptions were assessed one week post-consultation.

Main Results:

• Touch significantly increased medication adherence in both male and female patients.
• The positive effect of touch on adherence was more pronounced in male patients.
• Patients in the 'touch' condition perceived practitioners as more concerned and slightly more competent.

Conclusions:

• A simple, brief tactile intervention can enhance patient medication adherence in a primary care setting.
• This nonverbal technique offers practical benefits for healthcare providers aiming to improve patient compliance.
• The findings suggest touch positively influences patient-provider relationships and adherence outcomes.
