Which theorist's model is Dr. J most likely practicing from when he exaggerates couples' arguments and fears of divorce?

Dr. J is most likely practicing from the model of Haley when he exaggerates couples' arguments and fears of divorce. This approach comes from Strategic Family Therapy, which aims to create change through the use of tactics that disrupt maladaptive patterns. One common technique in this model is to amplify the presenting issues or conflicts within a couple's relationship to highlight extremes and elicit a change in their interaction patterns.

By exaggerating the arguments and fears, Dr. J may draw attention to the underlying problems that are often dismissed or minimized by the couple. This technique can help the couple see their situation from a different perspective, making it possible for them to recognize the dysfunction in their communication and ultimately work towards resolving their issues.

The other theorists listed focus on different aspects of family therapy. For example, Bowen's model emphasizes understanding family systems and intergenerational dynamics rather than exaggeration of issues. Minuchin concentrates on structural aspects of family interactions, while Straus tends to focus on communication and conflict behavior more broadly. Therefore, the strategic approach embodied in Haley's model best aligns with the described behavior of Dr. J.
