I am conducting a study to explore the quality of mental health care services rendered by the public heath facilities with the aim of developing a progress monitoring tool to improve the services offered.
The development a tool to assess psychological constructs is a very delicate work. Since you are asking this basic question, I am assuming that you don't have the background. You would need to use Psychometric theory and a very strong group of consultants with experience in test development and a solid statistitian. Best wishes,

Further more, this stuy (https://journals.sagepub.com/doi/abs/10.2466/pr0.1998.83.1.371?journalCode=prxa) developed a five factor theory of personality to measure mental health. It measures life scale, life orientation , self-actualization, social interest, and self-control, so this may be of use as well.
The useful theory is death-anxiety related to all mental disorders. There are lots of scales measuring this already. Contact the authors to this paper. They may be on RG:

Abstract
Death anxiety is considered to be a basic fear underlying the development and maintenance of numerous psychological conditions. Treatment of transdiagnostic constructs, such as death anxiety, may increase treatment efficacy across a range of disorders. Therefore, the purpose of the present review is to: (1) examine the role of Terror Management Theory (TMT) and Experimental Existential Psychology in understanding death anxiety as a transdiagnostic construct, (2) outline inventories used to evaluate the presence and severity of death anxiety, (3) review research evidence pertaining to the assessment and treatment of death anxiety in both non-clinical and clinical populations, and (4) discuss clinical implications and future research directions. Numerous inventories have been developed to evaluate the presence and severity of death anxiety, and research has provided compelling evidence that death anxiety is a significant issue, both theoretically and clinically. In particular, death anxiety appears to be a basic fear at the core of a range of mental disorders, including hypochondriasis, panic disorder, and anxiety and depressive disorders. Large-scale, controlled studies to determine the efficacy of well-established psychological therapies in the treatment of death anxiety as a transdiagnostic construct are warranted.
