PIEs in practice - by theme

NB: This page is in draft only.   Apologies for any delays or confusion, if you have found your way here, expecting more.

As with some other pages here, this section on PIEs in practice is being radically re-shaped, and over this period there may be many links which do not yet work. You will find some of theme gathered in a more eccentric selection, under 'Case studies and practice examples'  (HERE) almost all cases the items can still be found by browsing the main menus, or by searching the Library.


Time and again we have to stress that the phrase 'a psychologically informed environment', a 'PIE' -  both the general idea, and the framework that gradually emerged, to explain it - came into being first simply as an attempt to describe what we found actually happening already in some 'frontline' services.

We found - and so tried to describe this - in particular in homelessness services, as this was where, for historical reasons, much of the most inventive and engaged work with those most excluded was to be found, in the first years of the 21st century.

In consequence, the idea was taken up most enthusiastically there; and this has sometimes been understood as meaning that a PIE is something particular to homelessness services.

Nevertheless, the origins of this approach, and the thinking behind these first attempts to describe it and tease out the key features, go back far further, into the history of social psychiatry in the mid-20th Century (and beyond); and those developing PIEs can draw inspiration form emerging practice across a very wide range of services, client groups, and philosophies of care.

Here, simply for convenience, we divide these examples of practice into three broad clusters:

  • those that are primarily case studies of particular services;
  • those that focus on particular user groups, needs or settings; and finally
  • those that explore the connections and overlaps between the PIEs framework and other models or attempts to summarise 'what works', often in more specific contexts.

PIEs case studies – a selection of new and used material

NB: this collection of pages, and selection of examples, is incomplete. We are still gathering some of the material; but this will take some time; and these links and this material will be built up in stages. But the themes we currently propose to use are:

  • Introducing the PIE approach : HERE
  • The built environment and adaptations : HERE
  • Using the whole environment: HERE
  • Outreach, pathways, environments without buildings : HERE
  • PIEs, communities and a sense of belonging : HERE
  • Clubhouses, cores, and campus models : HERE
  • PIEs in therapy settings : HERE
  • 'Psychologically informed business environments' : HERE
  • Whole system PIEs  : HERE
  • PIEs and ‘exclusion-informed research’ HERE
