The paper demonstrates the use of couple data as a methodological tool. Using Straus's Conflict Tactics Scale as an example, it is shown that couple data may be used for the evaluation of scale items and for the assessment of the validity of frequency estimates of violence and its relationship with other variables. The results provide clear evidence that aggregate husband-wife data cannot substitute for couple data.
