Representing common ‘control variables’ in social research, the main variables included in this study were the sex of the survey respondent ([1] if female), age group (18–24, 25–34, 35–44, 45–59, 60+ and 0–4 and 5–17 if respondents reported on illness episodes of minors under their supervision), education (number of completed years of formal education), language ability ([1] if respondent spoke the main language of Thai/Lao in the respective study site), ethnicity ([1] if respondent belonged to the majority ethnic Thai/Khon Mueang groups in Chiang Rai or Lao Loum in Salavan), religion ([1] if respondent belonged to the majority religion of Buddhism in either site), occupation (comprising different types of precarious and secure employment such as daily labourers and drivers vs. contractual employees and government workers), housing conditions (on an ordinally decreasing scale from [1] stone, [2] wood and [3] natural materials), a wealth index (calculated on a scale from [0–1] of ownership of 16 common household assets and amenities such as a fridge and a rice cooker) and specific assets and amenities that likely influenced treatment‐seeking behaviour (electricity at home, water access, owning a motor vehicle) and the respondents' distance to the nearest markets and healthcare sources.…”
