What is the definition of instrumental values of choice? How to measure it?

Welcome.

I am deeply grateful.

Instrumental values refer to the values that serve as means to achieve other desirable ends or goals. They guide behavior and actions, contrasting with terminal values, which are valued for their own sake. For example, honesty is an instrumental value because it fosters positive relationships, leading to the terminal value of happiness.

Measuring instrumental values can involve qualitative methods such as surveys or interviews, where individuals express the importance of specific values in achieving their goals. Quantitative approaches may include rating scales to assess the perceived utility of various values in decision-making processes.
