GAD and health anxiety
How you do anything is how you do everything. - Zen Proverb
Here are a series of assessment questionnaires and handouts for Generalized Anxiety Disorder and Health Anxiety Disorder. Note that the 2010 Increasing Access to Psychological Therapies "IAPT Data Handbook" recommends using the GAD-7 to monitor progress in Generalized Anxiety Disorder and the short 18-item version of the Health Anxiety Questionnaire to monitor Health Anxiety progress.
GAD, 2 question screen - answering "yes" to either of the two screening questions on this sheet suggests it's worth checking for a diagnosis of full Generalized Anxiety Disorder (GAD) - for example by using the GADQ (see below).
