Final answer:
The single mother is experiencing role strain, which happens when the demands of a single role become too much to manage and cause an individual to feel overwhelmed.
Step-by-step explanation:
A single mother who is experiencing incompatibility within her status, such as not having enough time to both get adequate sleep and spend quality time with her children, may be experiencing role strain. This occurs when too much is required of a single role, leading an individual to feel overwhelmed by the duties expected of them, such as those of a parent, which may include cooking, cleaning, driving, and acting as a source of moral guidance. In contrast to role conflict, which arises when one has multiple roles with contradictory expectations, role strain focuses on the complications within a single role.
