Factor similarity of the Conflict Tactics Scales across samples, spouses, and sites: Issues and implications

Wide variations in prevalence estimates of marital aggression point to the absence of a uniform and adequate definition of marital aggression. To focus on the construct validity of Straus' (1979) Conflict Tactics Scales, the most frequently used measure of marital aggression, two studies were conducted. Based on responses to the Conflict Tactics Scales, two consistent factors (viz. Physical and Psychological Aggression) emerged in separate samples of 187 couples seeking therapy for marital problems, and 398 nonclinic couples in beginning marriages. The factor structure was consistent across clinic and nonclinic samples, sex, geographical sites, time, and socioeconomic status. Implications for the measurement of interspousal physical aggression are raised (e.g., mild, moderate, and severe aggression load on the same factor) and appropriate directions for further research on the construct validity of the Conflict Tactics Scales are suggested (e.g., conducting similar factor analyses on aggressive couples).
