Final answer:
The social worker should prioritize inquiring about the couple's coping styles and effectiveness, as these can significantly influence their marital dynamics and contribute to conflicts. This understanding is foundational to addressing the tensions in their relationship.
Step-by-step explanation:
When addressing the situation presented by the couple reporting increased marital conflicts, the social worker should first ask about the couple's styles of coping and their degree of effectiveness. These coping styles are critical to understanding how each individual deals with stress and how those methods are impacting their relationship. Inquiry into coping strategies provides insight into whether their current approaches are functional or contributing to the escalation in marital strife. Additionally, assessing communication can reveal dysfunctional patterns, but understanding their coping mechanisms can offer a more foundational perspective on the relationship dynamics. By addressing this, the social worker can identify the root of the issues and offer suitable recommendations for improving the couple's situation, which may range from individual coping strategies to joint communication enhancement techniques.
