MOPTS III: A technique for measuring PTSD


A technique is presented that measures the severity of PTSD as a result of a traumatic event. The technique is exclusively based on the symptoms of PTSD as defined by DSM IV. The level of distress of each symptom is measured on an 8 point scale by Ordered Metric (OM) Scaling which is quick to use, efficient, easily understood and unbiased. It uses words in the language and does not require people to form an analogy between a quality and their level of distress. The scale is within a person’s natural span of measurement. (7 +/- 2). Each symptom is regarded as independent of all others so the sum of the scores provides an overall measure. The technique is designed for repeated use, thus it can monitor progress in treatment. It is also a diagnostic technique. The technique is designed in such a way that the user will have no feedback about the level of distress he/she is conveying and this makes it very difficult deliberately to gain seriously high scores. The technique is administered and evaluated via a laptop computer. It is not designed for use by children.
