FIGURE 1—

Schematic of Markov microsimulation model used to estimate the potential costs and health benefits of school-based eating disorder screening.

Note. ED = specified eating disorder; OSFED = other specified feeding or eating disorders. “Specified” ED represents anorexia nervosa, bulimia nervosa, or binge-eating disorder. Students move between each health state (circle) based on probabilities derived from the literature. Arrows indicate pathways between heath states. Dashed lines indicate pathways modified by screening: (1) stay healthy for another year, (2) develop ED, (3) develop OSFED, (4) remain ill for another year, (5) progress to ED, (6) partially recover from ED, (7) recover, (8) relapse, and (9) remain recovered for another year.
