Validity And Reliability of The Thai Version of The Family Dermatology Life Quality Index

The study "Validity And Reliability of The Thai Version of The Family Dermatology Life Quality Index" aimed to assess the validity and reliability of the Thai version of the Family Dermatology Life Quality Index (FDLQI). The study included 100 family members accompanying 92 patients with dermatological diseases. The results showed a positive correlation between FDLQI and the global question of their Quality of Life (QoL) scores (rs=0.695, P<0.001), and between FDLQI and severity of the patient's disease (rs=0.578, P<0.001) as evaluated by family members. The FDLQI showed high internal consistency (Cronbach’s alpha=0.84) and test-retest reliability (ICC= 0.85). The study concluded that the Thai version of FDLQI demonstrated acceptable validity and reliability and can be used to assess the QoL of family members of patients with any dermatological diseases.
