Final answer:
The least major life event on the Social Readjustment Rating Scale (SRRS) is minor violations of the law, which have a value of 11 life change units (LCUs), indicating a minimal impact on stress levels.
Step-by-step explanation:
The Social Readjustment Rating Scale (SRRS), developed by psychiatrists Thomas Holmes and Richard Rahe, is a tool used to measure the amount of stress in people's lives by assigning numerical values, or life change units (LCUs), to 43 different life events that require varying degrees of personal readjustment. The event with the least amount of LCUs, considered the least major life event, is minor violations of the law, which is assigned a value of 11 LCUs. This suggests that while it is a life change that requires adjustment, it's considered to have the smallest impact on stress levels when compared to other life events listed in the SRRS.
