Person-centred Practice Index
by
Dr Paul Slater
Background
 Person-centred Practice
 Evidence relating to Person-centred Practice
 A dearth of psychometrically acceptable
instruments to measure Person-centred Practice
Background
 The Proxy measures: PCNI/PCCI tools
measured:
1.
2.
3.
4.
Work Stress
Job Satisfaction
Organisational Traits
Perceptions of caring
 Proxy measures – not direct measures
Background Summary
 Need to develop a tool that effectively measures
person-centred practice
 Establish the psychometric properties of the
instrument
PCPI Development
 Instrument Design: 5 Stage Process

Exploration of Theoretical Principles
Mapping to sample (Delphi technique)
Questionnaire development
Testing for reliability and validity
Amendment and acceptance
Person-centred Practice Framework (PCPF)
Delphi Technique
Two stages:
1. To gain agreement on the 17 definitions of
PCPF
2. Gain consensus on questionnaire items aligned
to the definitions
Delphi Technique
 Definitions generated
 Sample: International Expert Panel (n = 36)

Delphi Technique
Definition rated on 4-point Likert scale
Consensus achieved at
 80% (Keeney et al 2011)
 Median of 3.25 (Green 1982)
 Accepted definitions removed at each round
Consensus
 Round 1 - 11 definitions accepted (n = 26)
 Round 2 – 2 definitions accepted (n = 21)
 Round 3 – 4 definitions accepted (n = 19)
Item generation
108 potential items generated
 PCPRG and Expert Panel (Research Week)
 5-point Likert Scale
 “How well the items accurately measure the
definition”
 Response rate n = 26
 14 items removed:
The Person-centred Practice
Index (PCPI)
 Maps directly to PCPF
 Comprises 94 closed question items
 Measuring 17 Constructs
 Rated on 5-point Likert Scale
The Person-centred Practice
Index (PCPI)
 Currently testing psychometric properties:
• Large scale study in 4 Trusts
• Registered Nurses
• Finalise instrument items
 Initial findings very encouraging
• Strong measures of reliability and validity
• Questionnaire available Nov 2013
