The HidroQoL
PROM, Hyperhidrosis
The HidroQoL was developed in 2014 with qualitative patient and expert input. An 18-item questionnaire with three response options resulted. Following qualitative development, the initial validation was based on two observational studies. Overall, the instrument showed very good measurement properties supporting its use in clinical practice in order to assess the impact of HH on Quality of Life (QoL) [For this reason, the HidroQoL is a well-developed and validated PROM, which measures the QoL impacts in HH. With two main domains and 18 items in total, the questionnaire is short enough to exclude irrelevant topics but still is able to comprehensively assess the impact that HH has. The first domain with six items evaluates the impact of the condition on daily life activities (such as hobbies). The second domain captures the psychosocial life of the affected individuals (such as personal relationships) (see Fig. Main domains of the Hyperhidrosis Quality of Life Index (HidroQoL)
