Trial summary

Cancer of the oral cavity is one of the fastest growing cancers among men in Taiwan. Previous research has established a strong link between betel quid chewing, a common practice among Taiwanese men, and oral cancer. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 20 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 1. 47 participants will be invited to participate in a qualitative study that includes focus group and in-depth structured interviews that examine the social and cultural context that surrounds continued use and cessation of betel quid consumption. 2. 30 male and female healthy individuals who currently both chew betel quid and smoke cigarettes will be invited to attend 3 separate sessions at CMUH and complete a self-report questionnaire specifically designed to measure betel quid withdrawal symptoms, and the relationship between betel quid chewing and cigarette smoking withdrawal. This application represents the first step in the development of a multi-phase, multidisciplinary betel quid chewing research program.

Who may be able to join

  • Smoking and betel nut chewing habit and at least 20 years old to 65 years old and healthy people.

Who cannot join

  • 1. Less than 20 years old or greater than 65 years.

About this study

Cancer of the oral cavity is one of the fastest growing cancers among men in Taiwan. Previous research has established a strong link between betel quid chewing, a common practice among Taiwanese men, and oral cancer. However, despite the strong association, no attempt has been made to develop behavioral measures to facilitate betel quid cessation. This application extends upon existing collaboration between MD Anderson and China Medical University Hospital (CMUH) and seeks to characterize betel quid chewers and their withdrawal symptoms, in order to address an urgent cancer epidemiology issue in Taiwan.

Cancer of the oral cavity is one of the fastest growing cancers among men in Taiwan. Previous research has established a strong link between betel quid chewing, a common practice among Taiwanese men, and oral cancer. However, despite the strong association, no attempt has been made to develop behavioral measures to facilitate betel quid cessation. This application extends upon existing collaboration between MD Anderson and China Medical University Hospital (CMUH) and seeks to characterize betel quid chewers and their withdrawal symptoms, in order to address an urgent cancer epidemiology issue in Taiwan. In a two phase study, we will use a qualitative approach (guided focus group and interviews), followed by assessment of betel quid withdrawal in current chewers: 1) 47 participants will be invited to participate in a qualitative study that includes focus group and in-depth structured interviews that examine the social and cultural context that surrounds continued use and cessation of betel quid consumption, 2) 30 male and female healthy individuals who currently both chew betel quid and smoke cigarettes will be invited to attend 4 separate sessions at CMUH and complete a self-report questionnaire specifically designed to measure betel quid withdrawal symptoms, and the relationship between betel quid chewing and cigarette smoking withdrawal. This application represents the first step in the development of a multi-phase, multidisciplinary betel quid chewing research program. This program will enhance our understanding of the cultural and bio-behavioral aspects of betel quid chewing. Furthermore, it will lead to translational research projects that link behavioral findings to clinical treatments, and the eventual creation of a large scale, population-based prevention and education program.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02167295
Study groupRoleWhat they receive
Focus groupThe focus groups will consist of 6 to 8 persons each (N = 32). The focus group discussions will last for about 60 to 90 minutes. The discussion topics will be based on previous literature and experience and will include reasons for betel quid chewing or for quitting, pros and cons of betel quid chewing, barriers to and facilitators of abstinence, health beliefs and experiences about betel quid chewing and other issues.
In-depth interviews.We will conduct 15 one-to-one interviews, each lasts for about 45 to 60 minutes. Participants will be interviewed by a trained interviewer using a structured interview. The interview will be designed to collect information on socio-demographic background, current and/or former betel quid use, other substance use (smoking and/or alcohol consumption), as well as other variables including usage parameters, psychosocial and environmental influences on betel quid chewing, barriers to and interest in quitting, and knowledge of adverse effects on health.
Self-report questionnaireThis study is expected to enroll 30 participants who have smoking and betel nut chewing behaviors.Participants will complete 4 separate visits to CMUH, during which they will complete the same self-report questionnaire designed to measure withdrawal symptoms relating to betel quid chewing. To better measure betel quid withdrawal symptoms and to distinguish the 6 symptoms from those of smoking withdrawal, Participants will be required to attend one visit regular cigarette smoking and betel nut chewing behavior without restriction (as control), one visit after 12 hours of overnight betel quid deprivation (no cigarette deprivation), one visit after 12 hours of overnight cigarette deprivation (no betel quid deprivation), and one visit after 12 hours of both overnight betel quid and cigarette deprivation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Predictive validity of a self-reported measure of areca nut dependency scale.

    Measured: up to 28days

Secondary outcomes (1)
  1. Develop a self-report questionnaire that examines betel quid withdrawal

    To know reasons for betel quid chewing or for quitting, pros and cons of betel quid chewing, barriers to and facilitators of abstinence, health beliefs and experiences about betel quid chewing and other issues.And then, we propose to develop a self-report questionnaire that examines betel quid withdrawal among Taiwanese chewers who are also current cigarette smokers.

    Measured: focus group each lasts for about 60 to 90 minutes and one-to-one interviews each lasts for about 45 to 60 minutes.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive validity of a self-reported measure of areca nut dependency scale. (time frame: up to 28days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2015.
