Assessing person-centredness: the Person-centred Practice Indexby 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: • 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
Delphi Technique Two stages: • To gain agreement on the 17 definitions of PCPF • Gain consensus on questionnaire items aligned to the definitions
Delphi Technique • Definitions generated • Sample: International Expert Panel (n = 36) • Recognised Expert in the field • At least one publication in area • Willing to participate • Expert in questionnaire development (stage II only)
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
