Overview of model characteristics per domain
Response variate Outcome variable Y Outcome categories j Model type Covariates
Knowledge Knowledge sufficiency (based on Q2-8) j = 1 ( “Sufficient”) if at least 6 out of 7 questions have been answered correctly; j = 0 “Insufficient”) Logistic regression with random effects Forest cover (%), Urbanisation level (scale 1–5); Previous education; Perceived susceptibility (knowing persons with LB).
Perceived severity Consequence of tick bite: disease or itch (based on Q5) j = 1 (“Disease” ), Logistic regression with random effects Forest cover (%), Urbanisation level (scale 1–5); Previous education; Knowledge score ≥5; Perceived susceptibility (knowing persons with LB).
j = 0 (“Itch” or “Not sure”)
Perceived susceptibility Can you get ill? (based on Q9) j = 2 (“Yes”), Ordered logit with random effects Forest cover (%), Urbanisation level (scale 1–5); Previous education; Knowledge score ≥6; perceived severity; Perceived susceptibility (knowing persons with LB); Protective behaviour.
j = 1 (“Not sure”),
j = 0 (“No”)
Perceived importance Body checks important? (based on Q10) j = 2 (“Very important”), Ordered logit with random effects Forest cover (%), Urbanisation level (scale 1–5); Previous education; Knowledge score ≥6; Perceived severity; Perceived susceptibility (Can you get ill and Knowing persons with LB).
j = 1 (“Somewhat important”),
j = 0 (“Not important”)
Protective behaviour Body check frequency (based on Q12) j = 2 (“Often”), Ordered logit with random effects Forest cover (%), Urbanisation level (scale 1–5); Previous education; Knowledge score ≥6; Perceived severity; Perceived susceptibility (Can you get ill and Knowing persons with LB);Perceived importance.
j = 1 (“Sometimes”),
j = 0 (“Never”)

All j = 0 are considered reference categories in each model.
