Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants who do not meet recommended Australian health guidelines for smoking, nutrition, alcohol or physical activity behaviours will be provided with feedback outlining the Australian recommendations and strategies that can assist the participant improve these behaviours. Based on participant responses during the baseline survey, brief, one-off feedback for the relevant health risk will appear on the iPad screen during the baseline survey for the participant to read.

For each of the health risk behaviours that participants do not meet recommended guidelines they will also be offered the following online and telephone interventions:

Online interventions:
QuitCoach program (smoking): The QuitCoach is an online program that provides individual, tailored advice and support to assist smokers to quit smoking. The QuitCoach takes about 15-20 minutes to complete and creates a personalised quitting plan by asking users to answer a series of questions about their smoking, plans to quit, motivation, confidence and past quit attempts. The QuitCoach is designed to be used multiple times and for the user to return to the online program to review their current situation.

Healthy Eating Quiz program (nutrition): The Healthy Eating Quiz is an online program that takes about 10-15 minutes to complete and examines the user’s intake of a variety of foods including vegetables, fruits, protein foods, grains, dairy, water, sauces and condiments. The Healthy Eating Quiz can be completed several times with the program providing the user with the option to have a reminder e-mail sent to them in one month to complete the quiz again.

THRIVE program (alcohol): THRIVE is an online program that involves a 5-10 minute session of motivational assessment and personalised feedback about the participant’s drinking behaviour, strategies for reducing alcohol consumption, and information on available support services. The THRIVE program examines the participant’s alcohol intake in the last 12 months, past drinking, drinking in the last 4 weeks, blood alcohol concentration and other students’ drinking. THRIVE can be used multiple times and allows the user to assess their current situation.

10,000 Steps program (physical activity): The 10,000 Steps online program takes about 10-15 minutes to complete and encourages participants to use a pedometer to record their daily step counts on their personal step log, indicate their goal steps and monitor their progress towards increasing physical activity. The 10,000 Steps program is designed to be used multiple times to monitor daily step counts and physical activity levels.

Telephone interventions:
NSW Quitline (smoking): The NSW Quitline offers multiple telephone counselling calls to smokers to encourage and support them to quit. The NSW Quitline will offer six proactive telephone counselling calls over a one month period to smokers who set a quit date. These calls will last about 5-10 minutes and be scheduled on the initial call, on the quit date, and at 3, 7, 14, and 30 days after the quit date.

Get Healthy Information and Coaching Service (nutrition and physical activity): The Get Healthy Information and Coaching Service offers a coaching program that includes 10 coaching telephone calls with a health coach over six months. During the first call the health coach will spend up to 20 minutes talking to the participant about nutrition and physical activity. During the first three months the health coach will make up to six telephone coaching calls which will last about 10-15 minutes. The health coach will provide the participant with up to four 10-15 minute telephone coaching calls during the last three months to offer support.

Alcohol Drug Information Service (alcohol):The NSW ADIS is a telephone service that provides callers information about their alcohol use and associated risks, advice about effective interventions for reducing or stopping alcohol use, and counselling tailored to the caller’s needs. During the 10-15 minute telephone call, the ADIS counsellors will provide personalised advice about the short-term and long-term effects of alcohol, effective interventions for reducing alcohol consumption and strategies for dealing with situations that trigger excessive alcohol use. The participant can call ADIS multiple times.

Intervention adherence: As part of the 6-month follow-up survey the number of intervention group participants who self-report using each of the online programs and/or telephone services in the past 6 months and exposure to these interventions will be determined.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
TAFE classes will be stratified into vocational type and randomly selected until 100 classes participate. TAFE classes will be matched in pairs according to age groups of students and type of course (e.g. Manufacturing and Engineering, Hairdressing and Beauty) and randomly allocated to either the intervention or control condition. Students will be approached during class and those who consent to take part in the trial will be enrolled and will initially be asked to complete the baseline survey using an iPad. A computerised random number function will be used to allocate TAFE classes into condition.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation by using a randomisation table created by computer software (i.e. computerised sequence generation). An independent statistician will generate the randomisation table.

Efficacy
Statistical methods / analysis
Descriptive statistics will be used to present baseline characteristics for the intervention and control groups. Logistic regression will be used to test if there is a statistically significant different change in the prevalence of smoking between the two treatment groups. The outcome in the model will be smoking status and the predictors will include time, group and an interaction term between time and group. The p-value associated with the interaction term will be used to determine if there was a statistically significant difference in change between the groups. Linear regression will be used to test if there is a statistically significant different change in the mean level of the nutrition, alcohol and physical activity outcomes between the groups. The outcome in the model will be the persons’ value of the measure post treatment and the predictors will include their baseline value and treatment group (i.e. Analysis of Covariance). The p-value associated with treatment group will be used to determine if there was a statistically significant difference in change between the groups. Both the logistic and linear regression models will also be fit within a Generalised Estimating Equation framework to adjust for the correlation of responses within classes.

Sample size: As there are 5 primary endpoints (smoking, alcohol consumption, fruit intake, vegetable intake and physical activity) an alpha level of 0.01 will be used to adjust for the multiple comparisons. The prevalence of daily smoking in the control group at follow-up is expected to be 22%. We will recruit 1012 TAFE students at baseline (i.e. 506 per condition). Allowing for 20% loss to follow-up at 6 months, data will be available for 405 participants per condition. With an expected intra-cluster correlation coefficient (ICC) of 0.005 this will give the study a design effect of approximately 1.04 and an effective sample size of 389 per group, which will provide 80% power to find an absolute difference of 9.5% (in daily smoking rates) between the groups at the follow-up visit. Allowing for a higher ICC for the continuous outcomes (0.01), the study will have 80% power to detect an absolute difference of 0.25 SD in these measures at the 1% significance level, which equates to a difference of approximately 1.25 standard drinks of alcohol, 0.25 pieces of fruit, 0.25 vegetables and 50 MET minutes of physical activity.
