Development of Job Design Indicators for Generation Y Nurses at Tertiary Level Hospitals under Ministry of Public Health in Thailand

Abstract

Background: Job design is an essential and integral part of human resource management that its effect in
motivation Generation Y nurses to enhance and improve their performance. Job design is very important for
nurses and the productivity of nursing organizations, while job design indicators remain unclear.
Aim: To develop job design indicators in addition to assessing and validating job design indicators for
Generation Y nurses at tertiary level hospitals.
Method: The sample of this study was 360 Generation Y nurses in nursing units at tertiary level hospitals
under Ministry of Public Health in Thailand. The scale development process applied the steps of scale
development by DeVillis1 as follows: 1) definition of operational terms; 2) creation of questions from the
definition of terms; formation of 16 indicators of three components; 3) content validity testing by five experts
with a CVI of 0.91; 4) determination of the internal consistency reliability with thirty Generation Y nurses
in nursing units with a Cronbach’s Alpha Coefficient of 0.85 and 5) testing of the construct validity by using
confirmatory factor analysis.
Results: The research instrument for measuring job design for Generation Y nurses in nursing units at tertiary
hospitals under Ministry of Public Health in Thailand consists of three components with 16 indicators: 1)
job characteristics (factor loading .67)was composed of five indicators, 2) social interactions (factor loading
.98) was composed of six indicators, and 3) growth and learning (factor loading .65) was composed of five
indicators. The confirmatory factor analysis model of job design for Generation Y nurses in nursing units at
tertiary hospitals was congruent with the empirical data (CMIN/df = 1.24, RMR=0.02, GFI=0.97, AGFI=0
.94, RMSEA= 0.03, CFI=0.99).
Conclusion: The developed instrument should be used to measure job design for Generation Y nurses in
nursing units and for policy formulation in redesigning jobs at tertiary hospitals under Ministry of Public
Health in Thailand.
