IMPROVING LIFE SATISFACTION AND JOB SATISFACTION OF EMPLOYEES, THROUGH AN INTERVENTION TO THE SUPERVISORS

Abstract

The purpose of this research was to analyze the effectiveness of an intervention program to the supervisors, based on positive psychology and social skills, to improve life satisfaction and job satisfaction of their direct employees belonging to a public sector organization. To analyze the effectiveness of the intervention program, a quasi-experimental design with an inactive-control group was used. The intervention program was applied to a sample of immediate supervisors of a public organization of the health sector. Two groups were formed by the human resource unit: an experimental group of seven supervisors, and an inactive control group of eight supervisors. The effectiveness was evaluated in the direct subordinates (N=41) of the supervisors belonging to the experimental group, and in the subordinates (N=36) of the supervisors belonging to the control group. The intervention program lasted a total of one month and three weeks. Data analysis evidenced that the Factorial MANOVA 2X2 was statistically significant. When performing univariate contrasts, ANOVA interaction effect showed a statistically significant increase in life satisfaction and job satisfaction of the subordinates of those supervisors who received the intervention (experimental group), relative to the subordinates of the control group. Additionally, the effect sizes were of medium to high magnitude, depending on the index used for its estimation. Deploying efforts in supervisors intervention will bring benefits for their direct subordinates, such as a better evaluation of life satisfaction and job satisfaction.
