-56 survey101 for prisoners that adheres to the appreciative inquiry principles and was developed to identify the important qualities of a prison from the point of view of inmates or, i.e. the ‘things that really matter’ to prisoners (see also above, § 3.3.2; and in this series the Dossier).102 The idea is to better understand and improve prison life and its effects. To do so, the MQPL focuses on the dimensions of ‘respect, humanity, decency, help and assistance, staff–prisoner relationships, fairness, staff professionalism, security, prisoner safety, well-being and distress, personal development, family contact, and regime decency’.103 The MQPL survey that was used in a number of prison researches, including in Chile,104 Norway,105 Tunisia and France,106 can be used by NPMs to diagnose the presence of violence in prisons, to understand and document its negative effects107 and to find out ‘what really matters” for prisoners and their quality of life in prisons. NPMs could also dig deeper into the concepts behind the above-mentioned dimensions to better understand their interdependency and impact on everybody who lives and works in prison. GOOD PRACTICE NPM UK – The multiple-choice questionnaires for prisoners used by the HMIP of England and Wales during the course of each inspection, include, for example, detailed multiple-choice answer options for several questions on safety which are ‘ticked’ by the prisoners, thereby facilitating a consistent evaluation of the questionnaires according to common criteria.
