Expectancy-Value-Cost

The EVC scale was developed based on the Expectancy-Value model to understand motivational factors. This brief 10-item scale is designed to be a rapid measure reflecting student's perceptions of the extent they think they can be successful and the extent that they think a task is worthwhile. This scale allows differentiation between three separate motivational factors (expectancy, value, and cost). Additional research on the cost factor has been done, and a cost scale was developed to contribute to research on the Expectancy-Value Model. There are four subscales in the cost scale: task effort cost, outside effort cost, loss of valued alternatives cost, and emotional cost.
