About this study
Official title: Bridging the Knowing-Doing Gap: Implementing a Structured Reinforcement Programme on Micro-Skills in Motivational Interviewing for Primary Care Healthcare Professionals in Control of Blood Pressure Among Patients With Hypertension
The goal of this clinical trial is to improve hypertensive patients' systolic blood pressure (SBP) through increased application of MI micro-skills by mitigating known implementation barriers through a structured reinforcement programme delivered via digital nudges to Primary Care Healthcare Professionals (HCPs).
Secondary goals include examining implementation outcome measures through validated instruments, and participants' confidence levels in the application of MI that will be measured by a pre-and-post intervention short survey.

The main questions it aims to answer are:
- In primary care HCPs previously trained in MI, does undergoing a structured reinforcement program on MI micro-skills, compared to no reinforcement, result in lower patient SBP within 17 weeks of intervention commencement?
- How did intervention group participants' anticipated acceptability, appropriateness and feasibility compare with their perceptions after experiencing the intervention?
- Does confidence in the application of motivational interviewing (MI) change following the intervention among healthcare professionals in the intervention group?
Researchers will compare HCPs assigned to the intervention group with those assigned to the control group to determine whether structured reinforcement improves MI practice and is associated with differences in patient blood pressure outcomes.
Participants will:
- Be randomly assigned to either an intervention group or a control group.
- Complete electronic questionnaires at baseline and after the intervention period.
- If assigned to the intervention group, participate in a community of practice through the Teams channel and receive a structured reinforcement programme consisting of digital nudges delivered through a Microsoft Teams channel over 17 weeks.
- The digital nudges consist of bite-sized infographic-based learning materials focused on MI micro-skills and key principles.
Patient blood pressure data from eligible patients with hypertension managed by participating healthcare professionals will be extracted from routine clinical records in a de-identified manner for analysis.
Read the detailed description
This pilot two-arm parallel-group randomized controlled trial evaluates the effectiveness of a structured reinforcement programme designed to support the application of Motivational Interviewing (MI) micro-skills among primary care healthcare professionals (HCPs).
Although MI is an evidence-based approach for supporting positive health behaviour changes in patients, its implementation in routine clinical practice remains challenging due to competing priorities, time constraints, the complexity of MI techniques, and limited opportunities for reinforcement following formal training. This study seeks to address the "knowing-doing gap" by providing structured reinforcement after initial MI training.
Eligible doctors and nurses who have previously attended an introductory MI training workshop will be randomized to either an intervention group or a control group. Randomization will be stratified by profession to ensure balanced representation of doctors and nurses across study arms.
Participants assigned to the intervention group will receive a structured reinforcement programme delivered through a Microsoft Teams channel over a 17-week period. The intervention consists of bite-sized infographics focused on MI micro-skills and key principles. During the initial phase, participants will receive digital nudges twice weekly, followed by weekly reinforcement reminders for the remainder of the intervention period. Participants in the control group will continue with usual practice during the study period and will receive access to the educational materials after study completion.
Patient-level outcomes will be assessed using de-identified routine clinical data from eligible patients with hypertension managed by participating healthcare professionals. These data will be extracted by a Trusted Third Party (TTP) and analyzed at the study-arm level. Healthcare professional outcomes will include implementation outcomes and confidence in the application of MI.
The study aims to determine whether structured reinforcement improves the implementation of MI micro-skills in routine primary care practice and whether this is associated with improvements in systolic blood pressure outcomes among patients with hypertension.

Digital Nudges for Motivational Interviewing (MI) Micro-Skills ReinforcementBehavioural
A 17-week structured reinforcement programme delivered via digital nudges on Microsoft Teams comprising bite-sized infographic-based learning materials, and periodic reinforcement reminders designed to support the application of Motivational Interviewing (MI) micro-skills in routine primary care practice.
| Study group | Role | What they receive |
|---|---|---|
| Intervention Group | Experimental | Participants will receive a structured reinforcement programme on Motivational Interviewing (MI) micro-skills delivered through digital nudges and infographics via a Microsoft Teams channel over a 17-week period, in addition to usual practice. Receives: Behavioral: Digital Nudges for Motivational Interviewing (MI) Micro-Skills Reinforcement |
| Control Group | No intervention | Participants will continue with usual practice during the study period and will not receive the MI micro-skills reinforcement programme. Following study completion, participants will be provided access to the educational materials. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Systolic Blood Pressure
Change in systolic blood pressure (mmHg) from the index consultation (baseline) to the most recent routine-care blood pressure reading taken at least four weeks after the index consultation and within twelve weeks of the index consultation among eligible hypertensive patients managed by participating healthcare professionals.
Measured: Baseline and up to 12 weeks after the index consultation
Secondary outcomes (4)
Acceptability of Intervention Measure (AIM)
Perceived acceptability of the structured reinforcement programme on Motivational Interviewing (MI) micro-skills, measured using the four-item Acceptability of Intervention Measure (AIM). Anticipated acceptability will be assessed at baseline prior to intervention commencement, and experienced acceptability will be assessed after completion of the 17-week intervention. Higher scores indicate greater perceived acceptability.
Measured: Baseline and Week 17 (end of intervention)
Intervention Appropriateness Measure (IAM)
Perceived appropriateness of the structured reinforcement programme on Motivational Interviewing (MI) micro-skills, measured using the four-item Intervention Appropriateness Measure (IAM). Anticipated appropriateness will be assessed at baseline prior to intervention commencement, and experienced appropriateness will be assessed after completion of the 17-week intervention. Higher scores indicate greater perceived appropriateness.
Measured: Baseline and Week 17 (end of intervention)
Feasibility of Intervention Measure (FIM)
Perceived feasibility of the structured reinforcement programme on Motivational Interviewing (MI) micro-skills, measured using the four-item Feasibility of Intervention Measure (FIM). Anticipated feasibility will be assessed at baseline prior to intervention commencement, and experienced feasibility will be assessed after completion of the 17-week intervention. Higher scores indicate greater perceived feasibility.
Measured: Baseline and Week 17 (end of intervention)
Confidence in Applying Motivational Interviewing (MI)
Self-reported confidence in applying Motivational Interviewing (MI) in routine clinical practice, measured using a study questionnaire administered before and after the intervention.
Measured: Baseline and Week 17 (end of intervention)
