Control Over Shopping Decisions

What it measures

A four-item scale measuring a consumer's subjective sense of control over their shopping and spending decisions during a specific shopping episode. Items assess confidence in decision-making quality, self-determination of what to buy, control over purchasing, and financial self-control. Designed for retail and in-store shopping research, the scale captures the felt autonomy and competence dimension of the shopping experience.

Representative items

• I am confident about my ability to make good shopping decisions today.
• I decided on my own what to buy today.
• I was in control of what I purchased today.
