Design outcomes

Primary

Measure	Time frame
Change in feasible knowledge of stigma toward people with mental health problems measured using the Mental Illness and Disorder Understanding Scale(MIDUS) from the baseline to the post intervention	—

Secondary

Measure	Time frame
Change in behavioural intention measured using the Reported and Intended Behaviour Scale (RIBS-J) and help seeking intention toward themselves and people with mental health problems measured using help seeking intention questionnaires (Rusch et al. Psychiatr Serv 2011) from the baseline to the post intervention, and the 1-month and 12-month follow-ups. Change in the MIDUS score from the baseline to the 1-month and 12-month follow-ups was also compared. We also intend to define 25% or more decrease of RIBS-J score (1SD change from Koike et al. EPS 2016) from the baseline to each follow-up as the increase of stigma, and compare the number of those who have increase of stigma between the groups.	—
