A method for determining social interaction of a user wearing a hearing device which comprises at least one microphone and at least one classifier. The method comprises: receiving an audio signal from the at least one microphone and/or a sensor signal from the at least one further sensor; identifying, by the at least one classifier, one or more predetermined user activity values by evaluating the audio signal from the at least one microphone and/or the sensor signal from the at least one further sensor; and calculating a user social interaction metric indicative of the social interaction of the user from the identified user activity values, wherein the user activity values are assigned to predefined social interaction levels, and wherein the user social interaction metric is a function of the user activity values weighted with their respective contribution to each of the social interaction levels.
