Abstract
The 2010 Tonga Global School-based Student Health Survey (GSHS) was a school-based survey of students in Forms 2, 3, and 4.
The purpose of the GSHS is to provide data on health behaviors and protective factors among students to:
- Help countries develop priorities, establish programs, and advocate for resources for school health and youth health programs and policies;
- Allow international agencies, countries, and others to make comparisons across countries regarding the prevalence of health behaviors and protective factors; and
- Establish trends in the prevalence of health behaviors and protective factors by country for use in evaluation of school health and youth health promotion.

Sampling
Sampling Procedure
The 2010 TONGA GSHS employed a two-stage cluster sample design to produce a representative sample of students in forms. The first-stage sampling frame consisted of all schools containing any of forms. Schools were selected with probability proportional to school enrolment size. 24 schools were selected to participate in the TONGA GSHS.
The second stage of sampling consisted of randomly selecting intact classrooms (using a random start) from each school to participate. All classrooms in each selected school were included in the sampling frame. All students in the sampled classrooms were eligible to participate in the GSHS.
The Tonga GSHS was a school-based survey of students in Forms 2, 3, and 4. A two-stage cluster sample design was used to produce data representative of all students in Forms 2, 3, and 4 in Tonga.

Response Rate
For the 2010 TONGA GSHS, 2,211 questionnaires were completed in 24 schools. The school response rate was 100%, the student response rate was 80%, and the overall response rate was 80%.
Weighting
A weighting factor was applied to each student record to adjust for non-response and for the varying probabilities of selection. W = W1 * W2 * f1 * f2 * f3
W1 = the inverse of the probability of selecting the school;
W2 = the inverse of the probability of selecting the classroom within the school;
f1 = a school-level nonresponse adjustment factor calculated by school size category (small, medium, large). The factor was calculated in terms of school enrollment instead of number of schools.
f2 = a student-level nonresponse adjustment factor calculated by class.
f3 = a poststratification adjustment factor calculated by grade.

Type of Research Instrument
The GSHS uses a standardized scientific sample selection process; common school-based methodology; and core questionnaire modules, core-expanded questions, and country-specific questions that are combined to form a self-administered questionnaire that can be administered during one regular class period.
The TONGA GSHS questionnaire contained 89 questions addressing the following topics:
- Alcohol use
- Dietary behaviours
- Drug use
- Hygiene
- Mental health
- Physical activity
- Protective factors
- HIV infection
- Tobacco use
- Violence and unintentional injury
The questionnaire was developed by WHO and CDC once Tonga given their desirable and final questions as attached.

Data Processing
Cleaning Operations
The data set was cleaned and edited for inconsistencies. Missing data were not statistically imputed. Software that takes into consideration the complex sample design was used to compute prevalence estimates and 95% confidence intervals. GSHS data are representative of all students attending FORMS in TONGA.
