Why use the evaluation?

The IMPACT Toolkit takes the evaluation process one step further than any other perpetrator programme evaluation. Incorporating the quantitative measurement of the impact of the violent behaviour, it is the first tool to measure a change of the impact of violent/abusive behaviour as stated by the male programme participants and their (ex-) partners.

The outcomes you can evaluate with the IMPACT Toolkit are:

Behaviour change

  • Decrease in frequency, severity and types of violence by male participants in domestic violence intervention programmes towards their female partners or ex-partners
  • Changes in the impact of the violent/abusive behaviour on the victim/survivor



  • Increase in safety and feelings of safety by partners or ex-partners of men in programmes
  • Decrease in police callouts
  • Decrease in the partners or ex-partners feelings of fear/anxiety
  • Increase in the women’s well-being

Changes in the lives of children (as perceived by the parents)

  • Change of the children's situation (i.e. decrease of institution involvement)
  • Increase in children’s well-being
  • Decrease in impact of violent/abusive behaviour in children

Achievement of the hopes of clients and their partners/ex-partners

Attitude changes in male participants in domestic violence intervention programmes

  • Increase of their motivation to change
  • Increase in level of responsibility and accountability

Perceived changes as a result of the programme

In the final section of the questionnaire, there are two open questions. In the first one, the programmes are encouraged to be reflective, in that clients and (ex-) partners are asked if they feel there are any changes that the programme should make in order to help them better. In the second question, both parties are given space to offer information about anything else they would like to add.

All of those outcomes are retrieved

  1. At first contact
  2. At the beginning of the programme
  3. Halfway through the programme,
  4. At the end of the programme.
  5. At a six month follow-up after the programme is finished.

Both the male participants in the domestic violence intervention programme and their female partners or ex-partners fill out the questionnaires and thus give an insight into changes over time.

How is the IMPACT toolkit superior to other evaluation tools?

The Impact Outcome Monitoring Toolkit allows you to monitor and measure your programme outcomes in a standardized way, and to compare your programme outcomes with other programmes from your country or from other countries in the rest of Europe.

Additionally, the Impact Toolkit helps your programme to:

  • Develop a standardized procedure for contacting the (ex-) partners. Moreover, it also emphasises and enhances coordination of your PP with the victim/survivor services in your region.
  • Learn about your own self-evaluation process. Therefore, it helps you understand and overcome the flaws in your PP.
  • Gather quantitative and qualitative data about the programme outcomes, helping establish a follow-up procedure for the programme.
  • Develop a standardized reporting system, which is reader-friendly and targeted to your funders and donors.
  • Provide documentation of the process of evaluation you are using in your programme, which you can use to lobby at a local and national level.

How do you get started with the Impact Toolkit?

If you want to benefit from our toolkit:

  1. Contact the WWP EN Research and Development Manager Berta Vall Castelló at berta.vc(at)work-with-perpetrators.eu.

  • Training sessions on the Impact Toolkit for your staff.
  • Support on developing the outcome assessment of your programme.
  • Access to the online platform of the Impact Toolkit.
  • Access to yearly reports and PowerPoint presentations for your funders and government agencies (see section 3 for more information on the reports).
  • Access to a European dataset to compare PP across Europe (in development).
