Abstract
Objective: The study aims to investigate the contributions of self-efficacy, motivation, religiosity, social support, optimism, and subjective well-being as factors affecting quality of life on individuals with transfermoral amputation. Through empowerment, it is expected that there will be an increase in independence and socioeconomy. The ultimate goal of the empowerment process is for independence.
 Methods: This study used observational analytic with cross-sectional approach. The sample in this study was 110 post-transfemoral amputation patients. Data taken from questionnaires of self-efficacy, motivation, religiosity, social support, optimism, subjective well-being and quality of life were analyzed using structural equation modeling.
 Results: There was no influence of motivation on quality of life (critical ratio [CR]=0.535 <1.96; p=0.592 <0.05). There was a statistically significant positive effect of self-efficacy on quality of life (CR=3.082> 1.96; p=0.002 <0.05). There was a statistically significant positive effect of religiosity on quality of life (CR=2.919> 1.96; p=0.004 <0.05). There was no influence from social support for quality of life (CR=0.082 <1.96; p=0.935 <0.05). There was a statistically significant positive effect of optimism on quality of life (CR=2.307> 1.96; p=0.021 <0.05). There was a statistically significant positive effect of subjective well-being on quality of life (CR=2.089> 1.96; p=0.037 <0.05).
 Conclusion: The quality of life of patients with post-transfemoral amputation is positively and significantly influenced by optimism, religiosity, self-efficacy, and subjective well-being.
Highlights
Amputation causes a change to the people such as physical change, social change, psychological change, and environmental change in the long term [1]
It is tested by analyzing the value of the critical ratio (CR) and p value of the data processing result compared with the required statistical limits, it is above 1.96 for the CR value and it is below 0.05 for p value
The discussion follows: SEM analysis result shows that the CR value on the influence of motivation on the subject well-being in the table is 2.158>1.96 with p=0.031
Summary
Amputation causes a change to the people such as physical change, social change, psychological change, and environmental change in the long term [1]. Amputation has a big effect on human life because it causes people to lose many physical functions and abilities which are commonplace. Amputation aims to save the patient’s life and body, there are still many things which have a negative impact on the patient. The effect of amputation is that patient senses losing self-confidence; many people lack of enthusiasm in living because they cannot act as usual due to losing their limbs. Loss of confidence will be increasingly felt if the patient previously has a high social status [3]
