Comprehensive needs assessment of Child/Adolescent to Parent Violence (CAPV) in London (MOPAC)

Privacy Notice for the needs assessment

How we collect and use personal information

The Mayor’s Office for Policing and Crime (MOPAC) is the data controller for the personal information provided to undertake a needs assessment in relation to Child/Adolescent to Parent Violence (CAPV), to understand the efficacy of interventions and other practice models so MOPAC can make decisions about how CAPV assistance is funded in the future. We make decisions about what data is collected and how it is used. We have asked Ecorys UK Limited (Ecorys UK) to collect and process this information on our behalf. Ecorys UK are therefore data processors.

We need to collect Personal Data to undertake the needs assessment. We need to understand demographic information, nature/level of harm and impact of CAPV on individuals and families the views and experiences of young people, parent/carers and community/residents affected by CAPV and related harm/criminality, including drivers/risk factors for CAPV at local level; practitioner perceptions relating to the nature of problem and response, including evolution and efficacy.

Your participation in this research project is voluntary, you do not have to take part. If you do take part and change your mind later on you can withdraw from the research project at any stage.


It would be helpful to start by explaining some key terms used in this policy:

We, us, our Mayor’s Office for Police and Crime (MOPAC)
Personal Data Any information relating to an identified or identifiable individual
Special category personal data Personal Data revealing racial or ethnic origin, political opinions, religious beliefs, philosophical beliefs or trade union membership Genetic and biometric data (when processed to uniquely identify an individual)
Data concerning health, sex life or sexual orientation
Data subject The individual who the personal data relates to

Scope of Personal Data to be processed

The Personal Data that Ecorys UK will be obtaining for this project will be for research purposes only (not operation purposes). This data will be as follows:

How we will use information about you and what is the lawful basis for processing the information.

  • What we use your Personal Data for
  • Our reasons
  • To conduct research to understand the drivers, prevalence and nature of CAPV in London, provide insight into the experiences of children and families who experience CAPV, improve understanding of the range and efficacy of practice models and interventions being used in London, and thus inform future commissioning, policy and strategy for CAPV in London.
  • The reports produced as a result of the research will not identify you, they will only use anonymous data.
  • This research will not have any direct effect on you although it may lead to changes in the way we approach issues related to CAPV.

Processing is necessary for the performance of a task carried out in the public interest. Where we process special category data this will be on the basis that the processing is necessary for archiving purposes in the public interest, scientific or historical research purposes or statistical purposes.

  • if while taking part in the surveys, interviews and/or focus groups Ecorys UK believe there to be a risk of serious harm to participants or anyone else, Ecorys UK will have to ask for help and this may involve giving information to support services such as information about: the child or vulnerable adult (e.g. name, gender), about their family/support network (e.g. their next of kin and contact details), about the concerns (e.g. what has happened/nature of the concern, dates and times of significant events), about the alleged abuser, if known, and about other agencies involved.
  • To protect an individual’s vital interests

Who we will make your Personal Data available to

We sometimes need to make Personal Data available to other organisations. This includes contracted partners (who we have employed to process your Personal Data on our behalf to undertake the research) and/or other organisations (with whom we need to share your Personal Data for specific purposes).

Where we need to share your Personal Data with others, we ensure that this data sharing complies with data protection legislation. For the purpose of this project:

We only allow our service providers to handle your Personal Data if we are satisfied they take appropriate measures to protect your Personal Data. We also impose contractual obligations on service providers to ensure they can only use your Personal Data for the purposes outlined above and to provide services to us.

If you would like more information about who we share our data with and why, please contact us (see ‘How to contact us’ below)

Personal Data will be held at Ecorys’ offices, by the partner academics and in the offices of our service providers. We will not transfer any information we process about you outside of the UK.

How long we will keep your Personal Data

We will only keep your Personal Data for as long as we need it for the purpose(s) of this piece of work, after which point it will be securely destroyed. Please note that, under Data Protection legislation, and in compliance with the relevant data processing conditions, Personal Data can be kept for longer periods of time when processed purely for archiving purposes in the public interest, scientific or historical research, and statistical purposes.

Personal Data will be held in accordance with processing requirements stipulated by us. Once the processing is complete at the end of July 2021, the data will be retained for 90 days, after which it will be destroyed using a secure process, when we instruct Ecorys UK to do so.
