I've seen many MRAs use "70% of the non-reciprocal violence is by women" study way too many times. In fact, I've used it several times. But while reading the study today, I realized that the study does not encompass all of the violence in relationships.

If you look at the Limitations section, you can see that:

The 3 questions included in the Add Health study do not capture all forms of violence that occur between relationship partners, including many of the more severe forms of partner violence on the Conflict Tactics Scale (e.g., used a knife or gun, choked, or burned). Questions about emotional, verbal, psychological, or sexual aggression were also not included. Similarly, only a single item assessed injury to victims and it focused on injury frequency and excluded injury severity and whether medical attention was needed or sought. Thus, it is unclear whether the data presented here would be similar had the violence and injury assessment been more thorough or if different forms of violence had been measured and analyzed separately.

While we know from PASK that, females are more likely to commit unidirectional violence than men%2C%2028.3%25%20was%20female%20to%20male%20(FMPV)), we really cannot use this study as it's actually incomplete and really misses many crucial forms of violence.
