According to activity theory, what influences satisfaction during old age?

The correct answer highlights the central tenet of activity theory, which posits that a higher level and quality of engagement in activities leads to greater satisfaction and well-being in old age. This framework emphasizes that staying active—both physically and socially—contributes significantly to an individual's mental and emotional health as they age. In particular, engaging in various pursuits, whether they are hobbies, volunteer work, or social events, can enhance an older adult's sense of purpose and fulfillment.

While aspects like social interaction with family or being physically active are important in their own right, the core idea of activity theory stresses that the diversity and quality of those activities are what predominantly influence satisfaction. Therefore, it's the nature and extent of engagement in various activities that truly matter for achieving a fulfilling and satisfying experience during the later years of life.
