The "real world" is a construct, and some peculiarities of scientific thought become more intelligible when this fact is recognized ... Einstein himself in 1926 told Heisenberg it was nonsense to found a theory on observable facts alone, saying "In reality the very opposite happens. It is theory which decides what we can observe." - D. O. Hebb
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).
GAD, questionnaire (GADQ) - a simple questionnaire for making a full diagnosis of GAD.
GAD-7 plus - here is the IAPT recommended GAD-7 plus the other basic IAPT measures, the PH-9 and phobia scales.
GAD, metacognitions (Wells) - GAD assessment scale developed by Wells. Includes measures of safety behaviours and metacognitions.
GAD, brief measure of worry (BMWS) - a PDF of an interesting worry questionnaire developed by the Australian Black Dog Institute.
GAD, assessment (PSWQ) - the Penn State Worry Questionnaire (PSWQ) is possibly the most widely used measures for GAD. Here is a copy with some scoring information on the third page.
GAD, weekly assessment (PSWQ-PW) - you may find an adapted "weekly" version of the PSWQ is easier to use when monitoring therapeutic progress. Here is the PSWQ-PW, again with some scoring information on the third page of the download.
GAD, worry record (Borkovec) - Tom Borkovec and colleagues reported that about 85% of worries/fears that a GAD sufferer experienced never happened. For the 10-15% that did happen, they routinely found that the difficulty was coped with much better than the sufferer feared. This Worry Record encourages people to check this out for themselves - a good behavioural experiment.
GAD, worry tree and reducing worry tendencies - the Worry Tree is a helpful two slide Powerpoint handout for dealing with immediate worries. The Reducing Worry Tendencies is similar but looks more at the medium term. Tom Borkovec's hopes for the value of emotional/interpersonal additional work still needs to be validated before being taken as routinely relevant.
GAD, Powerpoint miniatures (Borkovec) - in the autumn of 2004, I spent a week with Tom Borkovec at Penn State University in the US. This 12 slide Powerpoint presentation is a short talk I subsequently gave about the experience and about GAD.
Health anxiety questionnaire (HAQ) - this 21 item health anxiety questionnaire yields four subscales, which can make it easier therapeutically to target specific behaviours like reassurance seeking. The third page of the download gives some idea of likely scores in different disorders.
Health anxiety inventory (HAI) - the 18 item (short form) HAI is the disorder specific scale recommended by the NHS Improving Access to Psychological Therapies (IAPT) initiative. The third page of the download gives typical scores for a Health Anxiety group, a more general anxiety group, a control group, and so on. The Centre for Anxiety Disorders and Trauma website also provides freely downloadable copies of the short form of the HAI scored for a week or a month and the long form of the HAI also scored for these two different time frames.
Health anxiety rating scale (Wells) - this health anxiety assessment questionnaire developed by Adrian Wells can be useful, particularly with a CBT approach, when tackling and quantifying safety behaviours like checking and reassurance seeking.
Health anxiety thoughts record - this is a fairly classic cognitive therapy thoughts record adapted for health anxiety.
