Final answer:
Cases requiring case management services after a family functioning assessment typically involve confirmed child maltreatment. Cases with no safety concerns or just positive caregiver feedback may not need immediate case management. However, school absenteeism could warrant case management depending on context and underlying issues.
Step-by-step explanation:
Following completion of a family functioning assessment - investigation, cases that will generally require opening for case management services are those where child maltreatment is confirmed (A). Case management services are important for ensuring child safety and welfare. They often entail working with families to address concerns, prevent further harm, and provide necessary support and resources. Case management may not be required for cases where there are no identified safety concerns (C) or where there are positives like caregiver testimonials (D). However, in certain circumstances, cases with issues such as children being absent from school (B) could also trigger a need for case management, especially if this absence is related to larger family or welfare issues.
For more information on child abuse and maltreatment, resources can be found through the U.S. Department of Health and Human Services which offer extensive data and support strategies related to child welfare. Additionally, research has illuminated the necessity of addressing barriers to success in case management, such as untreated trauma and intergenerational family dysfunction, to effectively support and assist children and families in achieving better outcomes.
