| Equation | (# participants) x (% participants who receive treatment solely because of the program) x (# QALY increase) x ($ QALY) |
| Explanation | This metric estimates the impact of post-traumatic stress disorder or depression treatment on lifetime health, estimated in terms of quality-adjusted life years (QALY). Number of participants: Reported by program. Percentage of participants receiving treatment solely because of program: [54%]. This is estimated by Constellation Fund staff based on data from SAMHSA (2017) which shows that 46% of individuals under 200% of the federal poverty level with any mental illness receive mental health care. Thus, we estimate that about 54% of participants would have not received treatment in the absence of the program. QALY increase: [0.15]. This is the value of the relief symptoms of severe mental illness from treatment of schizophrenia based on Andrews, Issakidis, C., Sanderson, S., Corry, J. & Lapsley (2004) and Carr, Lewin & Neil, 2006. $ value per QALY: [$50,000] Benefits are then discounted to present value based on the average age of participation to life expectancy. |
