What is the eNAPPA

eNAPPA is a valid, reliable and feasible instrument for the assessment of patient-related outcomes and severity of nail psoriasis to be used in clinical studies and daily practice.

eNAPPA is comprised of three components:

 1) NAPPA-QOL measuring nail-specific quality of life. It consists of 20 items that assess specific quality of life conditions in the past week. Answers are given in scales from 0 to 4.

2) NAPPA-PBI reflecting patient-relevant needs and treatment benefits. It consists of 24 items which assess patient-defined needs before and patient-rated benefits after treatment. Answers are given in scales from 0 to 4, and a global score is calculated based on the importance-weighted benefit items.

3) NAPPA-CLIN recording objective nail status. It assesses the least and the worst involved nail of both hands, or both feet, respectively. The scores range from 0 to 16 empirically.

How to use the eNAPPA

The NAPPA-QOL and NAPPA-PBI questionnaires are filled in by the patient himself. The questionnaire is self-explanatory; yet, patients can be supported if they are not able to fill it in by themselves.The NAPPA-CLIN is filled by the dermatologist or assisting persons. This part needs a basic understanding of clinical signs at the nails.

The three components (modules) have been developed and validated on an international basis. Thus, several language versions are available. The modules can be used independently from each other.
