About this study

A two-stage qualitative and quantitative study to provide insight into consumers' awareness of energy in alcoholic beverages, and how energy labelling effects consumer behaviour.

Read the detailed description

Rationale: In 2016/2017, one in five (19.5%) New Zealand adults (≥15 years and older) had an alcohol drinking pattern that carriers a risk of harming the drinker or another, and one in three (32.9%) young adults aged 18 to 24 years are hazardous drinkers. To reduce alcohol-related harm and help New Zealanders make positive decisions about their alcohol use, strategies are needed that not only inform them about health risks but also alter the environment they find themselves in on a daily basis. Unlike most packaged food products, alcoholic beverages are not required to present a statement of the composition of the product, such as amount of alcohol, energy or the nutrient content. It has been suggested that in the absence of this information, consumers of alcohol have no idea how much energy, alcohol or kilojoules they are consuming. Research indicates that nutrition labelling of food and non-alcoholic beverage products does impact consumer perceptions and product evaluations. A recent poll by Stuff showed that 83% of 3,300 New Zealanders indicated that they want to know what they are consuming and supported placement of ingredients and nutritional information on alcohol products.

Objectives: To provide insight into consumers' awareness of energy in alcoholic beverages, and in their views on energy labelling of alcoholic beverages. The project also aims to explore the effects of different types of energy labelling on consumers alcohol purchase behaviour.

Design: Two-staged qualitative and quantitative study.

  • Qualitative stage: Focus groups.
  • Quantitative stage: Four-arm randomised controlled trial. This qualitative stage aims to test the effects of three different types of alcohol energy labels on alcoholic beverages on (online) purchase behaviour, compared to a control (no label) condition, using an 'online shopping cart'.

Recruitment: Panel.

Sample size: Qualitative stage: n=36 (six focus groups with six people per group); Quantitative stage: n=600 (n=150 participants per experimental condition).

What is being measured

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

  1. Consumer online purchasing behaviour

    Consumer online purchasing behaviour assessed on an 11-point Juster scale (where 1 = no chance/almost no chance and 11 = certain/practically certain

    Measured: Measured immediately after randomization

Secondary outcomes (7)
  1. Purchase behaviour

    Number of alcoholic beverage(s) bought in the online shopping cart

    Measured: Measured immediately after randomization

  2. Perceived and estimated energy content of displayed product

    Assessed using a seven-point scale ranging from "very low" to "very high" and the estimated energy content of the product

    Measured: Measured at randomization

  3. Perceived confidence in estimating energy content of displayed product

    assessed using a seven-point scale ranging from "not confident at all" to "very confident"

    Measured: Measured immediately after randomization

  4. Intention to consume displayed product

    Assessed using a seven-point scale ranging from "would decrease consumption level" to "would increase consumption level"

    Measured: Measured immediately after randomization

  5. Attitudes towards displayed product

    On a seven-point rating scale participants will be asked whether they believe the displayed alcoholic product was expensive/cheap, unattractive/attractive, low quality/high quality, unhealthy/healthy, and taste bad/good.

    Measured: Measured immediately after randomization

  6. Support for displayed label

    On a seven-point rating scale participants will be asked whether they would support the implementation of the displayed label

    Measured: Measured at randomization

  7. Attitudes towards alcohol

    Assessed using the Scale for Measurement of Attitudes Towards Alcohol, a tool used to i) assess people's risk profile regarding the use of alcohol and ii) identify the factors that contribute to determining their attitudes

    Measured: Measured immediately after randomization

Questions about this trial

What is this clinical trial studying?

A study testing Intervention in people with Consumption, Alcohol and Drinking, Alcohol, run by University of Auckland, New Zealand at 1 site in New Zealand.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

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

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

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?

Consumer online purchasing behaviour (time frame: Measured immediately after randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03553043, which also lists 2 linked publications.

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 19 Aug 2021; AzTrials last refreshed its copy on 7 Nov 2026.
