|dc.description.abstract||Previous studies have identified occupational burnout and frustration of needs as
major variables influencing police personnel's quality of work-life and psychological
well-being in Nigeria. Less research attention has focused on how perceived
organisational support may affect the extent to which psychological needs and job
demands are related with quality of work life and psychological well-being. These
connections have implications for enhancing the well-being of police personnel,
especially in Nigeria. This study, therefore, investigated the extent to which psycho-situational
factors (psychological needs and job demands) predicted police personnel's
quality of work life and psychological well-being. It also examined the mediating roles of
perceived organisational support on the relations of psychological needs and job demands
to quality of work life and psychological well-being. The research employed a cross-sectional survey research design. Using
proportionate and simple random sampling techniques, 1,952 police personnel (867
females; 1085 males) with a mean age of 37.24 (SD=8.14) from 6 police headquarters in
the 6 south-western states in Nigeria participated in the study. The study instruments
were Basic Psychological Needs Scale (α=.87), Job Demands Scale (α=.78), Perceived
Organisational Support Scale (α=.81), Work-Related Quality of Life Scale (α=.85), and
Psychological Well-being Scale (a=.85). Six hypotheses were tested using hierarchical
multiple regression and structural equation modelling.
Results indicated that psychological needs significantly predicted quality of work
life such that police personnel who had opportunities to satisfy their psychological needs
tended to report a high quality of work life [β=.40; ΔR$^2$ =.15; F(8, 1943)=55.70, p<.01].
However, job demands did not have a significant influence on police personnel's quality
of work life [β=-.04, p>.05; ΔR$^2$ =.00; F(9, 1942)=49.82, p<.01].
The results further revealed that satisfaction of psychological needs significantly predicted police
personnel's level of psychological well-being [β=.28; ΔR$^2$ =.08; F(8, 1943)=26.35,p<.01],
while job demands led to a significant decrease in the level of psychological well-being
of police personnel [β=-.11,p<.01; ΔR$^2$ =.07; F(9, 1942)=26.34,p<.01].
The results of the mediation analysis, using structural equation modelling, showed that perceived
organisational support enhanced the extent to which psychological needs increased police
personnel's level of quality of work life; but it did not enhance the level at which job
demands reduced quality of work life of police personnel (x$^2$=0.00; df= 0; p<.001;
CFI=0.92; GFI=1.00; AGFI=0.96; RMSEA=0.04; NFI=1.00; TLI=1.00).
Perceived organisational support increased the extent to which psychological needs enhanced the
level of psychological well-being of police personnel; but it, however, reduced the level
at which job demands decreased their level of psychological well-being
(x$^2$=3.56; df=1; CFI=0.97; GFI=0.99; AGF/=0.99; RMSEA=0.03; NFI=1.00; TL/=0.98).
The findings of this study indicate that perceived organisational support and
satisfaction of basic psychological needs are important factors in police personnel's
quality of work life and psychological well-being. In order to enhance the quality of work
life and psychological well-being of police personnel, it is recommended that the
Ministry of Police Affairs in Nigeria should provide opportunities and support that
guarantee the satisfaction of their basic psychological needs.||en_US
