Final answer:
DeLongis et al.'s 1982 study explored how daily hassles relate to health status and found that these day-to-day stressors have a more considerable impact on psychological distress and physical health than major life events.
Step-by-step explanation:
In 1982, DeLongis et al. conducted a study focusing on the relationship of daily hassles, uplifts, and major life events to health status. This research is seminal in understanding how repeated small stressors, or daily hassles, can have a more significant impact on an individual's psychological distress and physical health than major life events. DeLongis and colleagues found that these daily hassles were more strongly associated with physical health problems than were life change events. Their work highlighted that the accumulation of daily minor stressors, particularly interpersonal conflicts, could lead to negative mood states and even physical health issues over time. This laid the groundwork for further exploration into how everyday stressors can contribute to chronic health conditions and psychological disorders.
