Table 3 Odds ratios of having 1 up to 4 MHD (mental health disturbances); 1 up to 3 MHD/4 MHD; and odds ratios of being in a higher numbered category (having 1 MHD more) by exposure type as compared to the province of Hainaut adjusted for sex, age and educational level at 5 and 14 months after the disaster

From: Does exposure type impact differentially over time on the development of mental health disturbances after a technological disaster?

  4. 3Proportional odds model (ordinal cumulative logit model).
  5. Use of weighted data for the reference population, the province of Hainaut, weight for the Ghislenghien population =1.
  6. The reference category is ‘having no MHD’.
  7. Quest.1: Ghislenghien n = 966 (direct witness SHD: n = 79, direct witness NSHD: n = 559, indirect witness: n = 328), Province of Hainaut n = 1231.
  8. Quest.2: Ghislenghien n = 499 (direct witness SHD: n = 43, direct witness NSHD: n = 290, indirect witness: n = 166), Province of Hainaut n = 1231.
