Intervento / TrattamentoIntervento / Trattamento |
|---|---|
|
Sperimentale: Gain-Framed
Participants receive messages that highlight the potential benefits of engaging in a specific behaviour (i.e., what positive outcomes they could experience from consuming milk and milk products).
|
Participants will be randomised to one of five message conditions.
Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day).
Participants in the Gain-Framed message condition will receive message content that highlights the potential benefits of consuming milk and milk products (i.e., high protein content, stronger hair and nail etc.)
|
|
Sperimentale: Loss-Framed
Participants receive messages that highlight the potentially loses of not engaging in a specific behaviour (i.e., what they could lose from not consuming milk and milk products).
|
Participants will be randomised to one of five message conditions.
Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day).
Participants in the Loss-Framed message condition will receive message content that highlights the potential losses of not consuming milk and milk products (i.e., lack of essential nutrients, less calcium).
|
|
Sperimentale: Self-Regulatory Efficacy
Participants receive messages that provide them with tips and strategies on how to engage in the consumption of milk and milk products (i.e., recipes, meal planning etc.)
|
Participants will be randomised to one of five message conditions.
Each condition will receive a total of four emailed messages on four consecutive days (i.e., 1 message per day).
Participants in the Self-Regulatory Efficacy message condition will receive information pertaining to how to include milk and milk products within their diet.
This information will come in the form of recipes, meal planning, food combining etc.
|
|
Sperimentale: Gain-Framed + Self-Regulatory Efficacy
Participants receive messages that highlight the potential benefits of engaging in a specific behaviour (i.e., what positive outcomes they could experience from consuming milk and milk products) and these messages also provide tips and strategies on how to engage in the consumption of milk and milk products (i.e., recipes, meal planning etc.).

Changes from baseline in calcium from dairy at 1 and 4-week follow up
Lasso di tempo: Baseline, 1-week follow-up, 4-week follow-up
|
Calcium consumed from dairy was assessed using a modified version of the "Calcium Calculator™" developed by the British Columbia Dairy Foundation.
The original tool assesses consumption of calcium from a comprehensive list of 30 commonly consumed calcium containing products.
For this study individuals were asked to indicate the portions they ate of 10 dairy products included in the list.
An explanation of a portion was provided for each item.
Milligrams of calcium consumed by participants on the previous day was determined for baseline, week 1 and week 4 follow-up.

Self-Regulatory Efficacy
Lasso di tempo: Baseline, Immedately after the Intervention (1-day), 4-Week Follow-Up
|
Changes in participants self-regulatory efficacy beliefs was assessed using an 18-item measure at baseline, 1-day after completion of the intervention and at 4-week follow-up.
Self-regulatory efficacy beliefs items were context specific.
Responses were scored on a scale of 0% (not at all) to 100% (extremely confident) with response options in 10% increments.

Outcome Expectations
Lasso di tempo: Baseline, Immedately after the Intervention (1-day), 4-Week Follow-Up
|
Changes in participants outcome expectations was assessed at baseline, 1-day after completion of the intervention and at 4-week follow-up.
The perceived likelihood of positive (16 items) and negative (5 items) outcomes occurring as a result of consuming milk and milk products was assessed using a 21-item measure.
Responses were scored on a 9-point scale from 1 (very unlikely) to 9 (very likely).

Outcome Values
Lasso di tempo: Baseline, Immedately after the Intervention (1-day), 4-Week Follow-Up
|
Changes in participants outcome values was assessed at baseline, 1-day after completion of the intervention and at 4-week follow-up.
The perceived value of positive (16 items) and negative (5 items) outcomes occurring as a result of consuming milk and milk products was assessed using a 21-item measure.
Responses were scored on a 9-point scale with a range of 1 (little value to me) to 9 (high value to me).
