Hodges' Model: Welcome to the QUAD: Problem solving, case formulation and policy formulation

Hodges' model is a conceptual framework to support reflection and critical thinking. Situated, the model can help integrate all disciplines (academic and professional). Amid news items, are posts that illustrate the scope and application of the model. A bibliography and A4 template are provided in the sidebar. Welcome to the QUAD ...

Problem solving, case formulation and policy formulation

On W2tQ this year, and possibly in a previous paper, or conference presentation, I've stated that the nursing process is basically a problem solving algorithm. Nothing profound there of course. 

'Problem solving' is a developmental threshold and an evolutionary skill obvious in humans, with learning passed on across generations. Evidence of problem solving in animals and nature is becoming increasingly apparent; with examples over recent decades of problems solved not witnessed before.

In healthcare, and psychotherapy more specifically, we shift to case formulation. Again a step-wise process to arise at a sufficiently complete rationale for therapy. Ideally, this extends beyond the individual. As an parent, grandparent, guardian, teacher, supervisor ... teaches a child so therapy is an opportunity for learning and, it must be added, unlearning.

Returning to (and passing on):

Hague, R., & Harrop, M. (2007). Comparative Government and Politics (7th ed.). New York, NY: Palgrave Macmillan.

Chapter 18 (pp.377-395) concerns 'Public Policy'. Clearly, here there is a shift from the individual to the collective, population and citizenry. The chapter's second page on 'Initiation and Formulation' quickly provides a flowchart 'Figure 18.1 Stages of the policy process'. Box 18.1 informs readers about 'Rational and incremental models and policy-making' (p.380):
'The key contrast between the two models is this. The rational model views policy formulation as emerging from a systematic search for the most efficient means of achieving defined goals. By contrast, the incremental model sees policy as emerging from a compromise between actors who have goals which are ill-defined or even contradictory. Where the rational model seeks the best policy in theory, an incremental framework seeks out a practical policy acceptable to all the interests involved.' p.380.
The book highlights Simon (1983) as a source for the rational or synoptic model:
 
Simon H.A. (1983) Reason in human affairs. Oxford: Basil Blackwell.

Plus, for the incremental model:

Lindblom, C.E. 1979. Still muddling, not yet through. Public Administration Review 39: 517–526.

If needed, online, you will find accounts and diagrams on problem solving, the nursing process, case formulation and policy formulation. That's quite a family is it not? 

While not referred to as explicitly today, the nursing process (now routinized) should address parity and integrate care across mental and physical health. The individual (person, patient) should be assessed and care planned with their social and community context taken into account. Collaboration in care should help assure that this is indeed the case. The nursing process in the sociological domain acknowledges the role of parents, guardians, and families as informal carers. The social care sector can also be represented and further the objectives of a more open and integrated care community as per the local situation. While not added to the sciences domain; case formulation should also factor in the physical and political. 

Politically, are all instances of problem solving, and formulation recognised for their importance and influence on outcomes and effectiveness, economy, efficiency (another 'box' p.357), plus efficacy? Are services politically afforded the resources, as defined across the domains of Hodges' model required to deliver, improve and change (achieve sustainability, educational, preventive)? 

The elephant here of course are the determinantS. Ultimately, all these forms of problem solving should be at 'home' in the political domain, but they are rarely there. It is not just the practitioner who can make the difference - be the difference.

Enough of l-implementation

Policy needs to be fit for 21st century purposes, and not hollowed-out but allowed out - beyond the legislative walls where it can make a real difference.
