  1. Data were compared by independent sample T test or one-way ANOVA
  2. PWMI  People with mental illness
  3. aThere were significant post hoc (LSD) tests between age (18–30 years) and age (61–75 years) (p = 0.015), between age (31–45 years) and age (61–75 years) (p < .001), between age (31–45 years) and age (> 75 years) (p = 0.028) and between age (46–60 years) and age (61–75 years) (p = 0.003), showing that the age group (> 60 years) has highest SDSC scores
  4. bThere were significant post hoc (LSD) tests between educational level (primary schools and below) and educational level (technical secondary school and junior college) (p = 0.001), between educational level (primary schools and below) and educational level (bachelor’s degree or above) (p = 0.030), between educational level (junior high school) and educational level (technical secondary school and junior college) (p = 0.004) and between educational level (high school) and educational level (technical secondary school and junior college) (p = 0.003), showing that the educational level group (technical secondary school and junior college) has lowest SDSC scores
  5. cThere were significant post hoc (LSD) tests between socioeconomic status (low class) and socioeconomic status (medium class) (p = 0.021) and between socioeconomic status (low class) and socioeconomic status (medium–high class and high class) (p = 0.010), showing that the educational level group (medium–high class and high class) has lowest SDSC scores
  6. dThere were significant post hoc (LSD) tests between contact or familiarity with PWMI group (no-contact or familiarity with PWMI) and contact or familiarity with PWMI group (contact or familiarity with PWMI) (p < 0.001), between contact or familiarity with PWMI group (no-contact or familiarity with PWMI) and contact or familiarity with PWMI group (all-contact or familiarity with PWMI) (p = 0.046), showing that the contact or familiarity with PWMI group (no-contact or familiarity with PWMI) has highest SDSC scores
