Behavior and Behavior Mechanisms, Hypertension
Conditions
Brief summary
This study aims to examine the feasibility and effectiveness of written behavioural persuasion techniques intervention to encourage treatment initiation and follow-up for hypertension management among the untreated hypertension population of the SEACO cohort.
Detailed description
Each household is given a unique identifier called house\_id in the SEACO database. The randomisation will be computer-generated according to their house\_id with a ratio of 1:1. During the house visit, participants' blood pressure will be taken three times, and the final reading will be the average of the second and third readings. Participants will be assessed based on the inclusion and exclusion criteria, i.e., age 35 years and above, blood pressure reading and reported not being diagnosed with or treated for hypertension. At the end of the house visit, all participants will receive a standard referral leaflet, and participants randomised to the intervention group will receive an additional written behavioural persuasion leaflet.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants who see a doctor because of high blood pressure | Follow-up after 4-6 weeks receiving the leaflet | The number of participants who see a doctor because of high blood pressure |
| Participants' intention to go see the doctor about their blood pressure (6-point Likert scale) | Follow-up after 4-6 weeks receiving the leaflet | 6-point Likert scale (strongly agree, moderately agree, somewhat agree, somewhat disagree, moderately disagree, strongly disagree) to measure participants' intention to go see the doctor about their blood pressure - I intend to go to the doctor about my blood pressure, I plan to go to the doctor about my blood pressure, I want to go to the doctor about my blood pressure) |
| Participants' awareness of receiving the written communication during the health visit and their perceptions of the leaflets (6-point Likert scale) | Follow-up after 4-6 weeks receiving the leaflet | 6-point Likert scale (strongly agree, moderately agree, somewhat agree, somewhat disagree, moderately disagree, strongly disagree) to measure participants' awareness of receiving the leaflets during the health visit and their perceptions of the leaflets' content, usefulness, impact on seeking medical attention, and aesthetic appeal - The leaflets contain useful information, The leaflet was helpful. It made it easier for me to see a doctor and manage my blood pressure/ It would make it easier for me to see a doctor and manage my blood pressure, The leaflet was persuasive. It made me want to see a doctor for my blood pressure, I like the colour and design of the leaflet. |
| 12-item Health Literacy score | Follow-up after 4-6 weeks receiving the leaflet | 12-item Health Literacy is a validated, self-reported instrument used to measure health literacy (HL). The index value for HL is obtained where 0 represents the lowest HL and 50 the highest HL |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time taken for clinic visit (week) | Follow-up after 4-6 weeks receiving the leaflet | Time taken (week) for participants to go see a doctor because of high blood pressure after receiving the leaflet |
| Blood pressure status during clinic visit | Follow-up after 4-6 weeks receiving the leaflet | Participants' self-reported blood pressure status during the visit to the clinic/doctor (low, normal, high) |
