What is the operational definition of commitment?

Answer 1

There is not, to my knowledge, any one single or over-arching operational deifinition/OD of 'commitment'. The nature of ODs, in psychology anyway, is that they vary according to the background of the researcher in question (amongst other things). You could consider many different aspects of commitment- I assume you're talking about commitment in terms of relationships, right?- and come up with an OD for each. For example, one that comes to mind is: Not having relations with other women/men. Then there's the more complex factor, difficult to operationalize, of 'mental infidelity', of thinking about being unfaithful with other people. Such variables strike me as far more difficult to operationalize [than the previous example].
