The timeline followback spousal violence interview to assess physical aggression between intimate partners: Reliability and validity

The psychometric properties of the Timeline Followback Spousal Violence interview (TLFB-SV), a calendar method used to assess daily patterns and frequency of spousal violence, were evaluated. Men (N = 104) entering a spousal violence treatment program, along with their female partners, were interviewed with the TLFB-SV at pretreatment, posttreatment, and quarterly thereafter for 1 year and asked to identify days of male-to-female and female-to-male physical aggression that had occurred between them. For posttreatment and follow-up interviews, participants maintained a weekly diary, in which they catalogued the days on which acts of spousal violence occurred. The subscale scores derived from the TLFB-SV, the proportion of days of any violence, and proportion of days of severe violence for each partner were calculated for each assessment interval. The TLFB-SV subscales had excellent temporal stability and concurrent and discriminant validity. Interpartner agreement on TLFB-SV subscale scores and agreement between partners on days when spousal violence occurred was low at pretreatment, but was high for the other assessment periods.
