Burden Scale (BS)
This BS is an original version. The 16-item rating scale was developed originally for Thai caregivers by Professors Tinakon & Nahathai Wongpakaran. It has 5 response options in Likert type, from 0 = never to 4 always. The minimum score is 0; maximum 64. The internal consistency was 0.86 (Cronbach’s alpha) when testing among 137 family caregivers of older persons who visited a geriatric psychiatry clinic.
Caregivers’ burden can be interpreted as follow;
0 = none, 1-6 = low, 7-27 = medium, 28-33 = high, and 34-64 = extremely high.

This shorter version (BS-12) was first time introduced at IPA Spain 2019, September.
