Mixed and Match vs One-size-fits-all

March 22, 2022 updated by: Dr Katherine Lam, The Hong Kong Polytechnic University

Mixed and Match Versus One-size-fits-all: A Randomized Controlled Trial of Self-determination Theory on a Menu of Smoking Cessation Options (SDTM) Among Adult Smokers

Most existing smoking cessation services are based on '5A's' and '5R's' models which are recognized by the World Health Organization as a standardized tool for smoking cessation. While there are more techniques that are known to be effective and could be incorporated in existing smoking cessation interventions to further promote their effectiveness. This study is to examine the effectiveness SDTM in assisting adult smokers in Hong Kong to quit.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A randomized controlled trial (RCT) will be conducted. One-hundred adult smokers aged 25 or above will be recruited from smoking hotspots in Hong Kong. Participants in the intervention group will be contacted by our trained research assistant to receive a telephone counselling session at baseline. Participants can choose to receive their own smoking cessation treatment options from our menu. Control group participants will only receive a self-help quitting leaflet

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Self-reported abstinence at 6-month follow-up
Time Frame: At 6-month follow-up
participants will be asked about their self-reported abstinence in the past 7 and 30 days
At 6-month follow-up
Biochemically validated abstinence
Time Frame: At 6 months follow-up
validate the self-reported abstinence if the level of carbon monoxide in expired air was less than 4 parts per million and saliva cotinine level was less than100 ng/mL in parallel tests
At 6 months follow-up
Self-efficacy at 6-month follow-up
Time Frame: At 6-month follow-up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
