Ilness Attitude Scale (IAS) Flow

Illness Attitude Scale flow

Introduction

The Illness Attitudes Scale (IAS) is a self-rated measure that consists of nine subscales designed to assess fears, attitudes and beliefs associated with hypochondriacal concerns and abnormal illness behaviour [1]. In the original list 9 subscales were distinguished. Subsequent validation studies lead to two subscales: disease anxiety and disease behavior [2,3]

The Illness Attitude Scale flow contains the Ilness Attitude Scale (IAS) questionnaire and associated calculation. After form submission, the Illness Attitude Scale calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the Illness Attitude Scale calculation.
