Based on the theoretical foundations of the caregiving system model, which holds that prosocial behavior can be conceptualized in relation to a neurobiological stress-buffering mechanism, we addressed the question of whether daily volunteering yields buffering effects in terms of suppressing a neuroendocrine response (i.e., salivary cortisol) to daily stressors. We used daily diary data from the second wave of the National Study of Daily Experiences (NSDE II), which is part of the Midlife in the United States study (MIDUS II), a nationally representative survey of middle-aged and older adults.
