The GAD-7 is a self-reported questionnaire for screening and severity measuring of generalised anxiety disorder (GAD), copyrighted by Pfizer. GAD-7 has seven items, which measure severity of various signs of generalized anxiety disorder according to reported response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day.” Assessment is indicated by the total score, which is made up by adding together the scores for all seven items.

The Outcome Rating Scale is an ultra-brief 4 item visual analogue scale that measures 4 domains; individual, interpersonal, social and overall, using 10cm lines in the paper version. Being quick to administer and score and with focus on more open areas rather than specific elements of distress it is ideal for use on a sessional basis in a wide variety of contexts.

The Emotional Needs Audit is a simple diagnostic questionnaire developed by the Human Givens Institute which helps to identify unmet need. A peer reviewed article has been published on its reliability and validity (see here) although there are no data available as yet about it as a measurement of change in treatment.

The Pragmatic research Network 14 item measure (PRN-14) is based on the evolution of the work around the ENA, described above. Through an iterative process of development, including factor analysis, use of focus groups and continuing feedback from users the measure has matured to its current form. It's in use in the UK and USA. In addition to items concerned with unmet need, other items around functioning, which are more sensitive to change, are included. Currently research is in progress to look at the sensitivity of the instrument to change in treatment and how well it correlates with other well validated instruments.
