This study updated the findings of the Second Responder Programs on Repeat Incidents of Family Abuse systematic review and meta-analysis.


The objective of this study is to update and extend the findings of the prior second responders systematic review and meta-analysis in addressing Second Responder Programs on Repeat incidents of Family Abuse. This is done by synthesizing the results of published and unpublished second responder evaluations through October of 2021. This review also examines the use of victim services as a secondary outcome and incorporates a number of additional moderator analyses. Five new studies were identified between 2004 and 2019, all of which contained sufficient data for the calculation of at least one effect size. Along with the 10 studies included in the prior review, a total of 15 studies and 29 distinct effect sizes were analyzed across three outcome constructs. Effect sizes were calculated as logged odds ratios and results were synthesized using random effects models with restricted maximum likelihood estimation. Results were exponentiated to represent the percentage point difference in the odds of a given outcome for treatment groups relative to control groups. (Published Abstract Provided)
