*1: K6 = Scale to measure the levels of depression and anxieties

Respondents reply to each question of a six-item questionnaire concerning the frequencies with which they felt depressed or anxious during the past 30 days (such as "Have you felt extremely nervous?" or "Have you felt desperate and helpless?”). This survey targets people aged 16 or older to ascertain whether any mood or anxiety disorder poses a problem in their daily lives, based on their responses.
