SAH isa trauma-informed 12-week intimate partner violence (IPV) intervention program.

SAH is a group trauma informed intervention that uses motivational strategies and self-monitoring of one's thoughts and responses. It provides a unique fusion of interventions for trauma and IPV and consists of 12 two-hour weekly sessions. Throughout the program, group members complete in-session practice exercises and are provided "practice assignments" to consolidate and apply information learned in group.

The Revised Conflict Tactics Scale (CTS2) is a 39-item measure of individual engagement in or experience of physical or psychological violence with an intimate partner. Each item is asked about both the respondent and the respondent's partner, for a total of 78 questions.The response options include 8 choices (Categories 1-7 and 0). An answer of Category 1 or 2 is coded as the corresponding number of times the specified incident occurred (once or twice in the past year). For Categories 3-5, the midpoint of the category is coded. For example: Category 3 (3-5 times) is coded as 4, Category 4 (6-10 times) is coded as 8, and Category 5 (11-20 times) is coded as 15. Category 6 (More than 20 times) should be coded as 25. Category 7 is given a score of 0 if scores for the previous year do not reflect abuse or conflict. Total scores can range from 0 to 975 and lower scores suggest less conflict.

The 7-item Restrictive Engulfment subscale of the Multidimensional Measure of Emotional Abuse (MMEA) will be used as an additional measure of psychological IPV. Each item has 7 potential responses from 0=never to 6= more than 20 times. Scores can range from 0 to 42, with higher scores being associated with more psychological IPV.

Scores range from 0 to 80 with higher scores associated with more PTSD symptoms. A total score of 33 or higher may indicate severe PTSD.

Alcohol use will be assessed by the Alcohol Use Disorders Identification Test (AUDIT). AUDIT has 10 questions and the possible responses to each question are scored 0, 1, 2, 3 or 4, with the exception of questions 9 and 10 which have possible responses of 0, 2 and 4. The range of possible scores is from 0 to 40 where 0 indicates an abstainer who has never had any problems from alcohol.
