Primary

Measure	Time frame
Changes in the NRS score for willingness to try LAI treatment if recommended by a physician (Q4), assessed before video viewing, after video (I), and after video (II).	—

Secondary

Measure	Time frame
As secondary outcomes, the associations between willingness to initiate LAI treatment assessed by a Numerical Rating Scale (NRS) and Ten Item Personality Inventory Japanese version (TIPI-J) scores, Positive and Negative Syndrome Scale scores, age, sex, and duration of illness will be examined. In addition, changes in the NRS scores for three questionnaire items will be examined across three time points: before video viewing, after viewing video (I), and after viewing video (II). The items are (Q1) "LAI treatment is effective in preventing relapse", (Q2) "Receiving LAI treatment is expected to stabilize daily life", and (Q3) "I feel reassured about receiving intramuscular injections".	—
