    Scope

    Notes

    In order to achieve the objectives of this survey, a nationally representative sample was targeted in order to achieve the necessary scope and coverage required for this

    national survey. The sample population consisted of 13,988 participants aged 18 years and old from 6,254 households that comprised of 434 sample clusters. The 434

    sample cluster populations consisted of 64 urban area and 370 rural or rural villages.

    In each sample cluster, 11 households were selected at random from each urban area and 15 households were selected at random from sample villages in rural areas.

    Seventeen sampling domains were considered in separate strata at the stage of sampling selection of clusters. The survey was designed to cover all private households including single member households. The exclusion criteria include household such as military barracks, prisons, hospitals and boarding houses.

    The scope of the survey is sufficiently wide to meet the objectives mentioned above. A random sample of 10710-targeted populations 18 year old and over, 6254 sample households and 434 sample clusters will be covered for collecting data through two main questionnaires, Form 1 and Form 2. Out of the 434 sample villages, 64 will be from urban area. Another 370 villages will be covered will be covered in Rural areas. 11 households will be selected at random from each sample village in urban areas and 15 households will be selected at random from sample village in rural areas. Table 1 below shows the number of excluded villages by province

    Seventeen domains were considered as separate strata at the stage of sampling selection of villages. The survey has been designed to cover all private households including single-member households. Persons living in institutional households like military barracks, prisons, hospitals and boarding houses will be excluded.

    The core questionnaire of Survey had as its primary objectives:

    1. Demographic information

    Sampling

    Sampling Procedure

    The sample population was representative of 12 individual provinces and five groups of provinces. The sample population was stratified in three stages. Initially, the whole sample population was divided by domain: urban and rural then by other criteria. All potential participants from each selected household were interviewed. In consideration of sampling techniques and the sample size (about 13,988 eligible participants 18 years of age and older), this survey report is considered a nationally representative survey of tobacco use among the general populations within the Royal

    Cambodian Kingdom (Please see external resources of Sampling Design and Sample Size in PDF format).
    Response Rate

    The end result of all interviewing yielded a 97% percent response rate.
    Weighting

    A list of households was compiled for every sample village (or segment of sample village) and was necessary

    to select sample households for use as an input to derive household weights. Because the sample was stratified by domain, it is not self-weighting. For reporting the national level results, sample weights were used. Variable weight is to be used to weigh records at the individual level.

    Survey instrument

    Questionnaires

    Two main questionnaires were canvassed for this survey. Form 1 (Listing of Households), Form 2 (Core Questionnaire)

    1. Form 1 was filled up for the listing of households in every sample village (or segment of sample village) only.

    2. Form 2 contains about 103 items including demographic characteristics, tobacco use, knowledge and attitudes about tobacco use, exposure to second hand smoke, smoking cessation activities, lifestyle habits, exposure to tobacco media advertisements, and other miscellaneous questions. Information was collected from sample households within sample village (or segment of sample village).

    Supervision

    In general, one supervisor is assigned to supervise several interviewers during the field operations. The major duties and responsibilities of supervisor in relation to the work of interviewers are the follows:

    The supervisor is responsible for ensuring that all the interviewers do the listing and interview work satisfactorily in time, effectively and completely in the selected areas.

    The supervisor is required to check all the questionnaires filled by interviewers.

    The supervisor visits the enumeration area to check the complete questionnaires and re-interview a few sample households to check whether the information the interviewers have collected are accurate, reliable and valid or not.

    The supervisor may provide to interviewers all necessary field supplies and questionnaires for fieldwork operation etc.

    The supervisor serves as a link between interviewers and survey coordinators. The supervisor must inform any problem or difficulty that you or interviewers encounter during the fieldwork operation and then deal with the problems. The supervisor must help interviewers assigned under you establish contact with village chiefs, commune chiefs, and other authorized representatives of the village, commune etc.

    The supervisor has to prepare a time schedule for meeting all interviewers at their respective assigned villages for checking the work done etc.
    Data Collection Notes

    A total of 86 interviewing staff and their supervisors were recruited and trained by the National Institute of Statistics and the Ministry of Planning. All staff members hired for data collection activities were trained covering the interview process (concepts, definitions) and filling out the questionnaires. All training of participating staff was completed within five days.

    Data processing

    Data Editing

    Manual processing of questionnaires verified status of completeness, correctness, and consistency of the data entries. The coding classification of Occupations and

    Industries was used and were developed for the Cambodian National Tobacco Survey. The coding and classification scheme were based on the UN International Standard Occupations Classification (ISOC) and UN International Standard Industrial Classification (ISIC) systems, respectively. Manual editing and coding were performed by four persons (one supervisor and three processors) all of them from NIS. They participated in editing and coding of many surveys conducted by NIS.

    Data appraisal

    Estimates of Sampling Error

    Substantial differences (sampling error of > 10%) results in the addition of sample points and subjects on a per domain basis until the comparability with current national data is achieved
