B. The findings have been too inconsistent to draw any conclusions.
C. While the effects of divorce are negative on children, the effects on the spouses are generally positive.
D. Due to modern acceptance of divorce, there has been an ongoing decrease in the negative effects of divorce.

Correct answer: A

Rationale: The correct answer is A because it highlights a crucial factor that makes it challenging to establish a clear cause and effect relationship between divorce and the psychological functioning of family members. Preexisting behavioral abnormalities in either the parents or the children may influence both the likelihood of divorce and the psychological functioning of family members. Choice B is incorrect as it generalizes the findings without specifying the key issue of preexisting conditions. Choice C is incorrect as it oversimplifies the effects of divorce on family members. Choice D is incorrect as it presents a broad statement without addressing the complexities involved in determining the effects of divorce.
