Measuring Efficacy with Psychometric Instruments

Psychometric instruments are used in the NHS, the voluntary sector and in research to assess therapeutic effectiveness. I digitalised some of these questionnaires as many people use the internet as a starting point in their healing journey. All the instruments below are based on self reported data which means they represent a subjective snapshot in time. This means the scores are likely to fluctuate over time and depend on how you feel.

Depression and Anxiety

The most common and widely used in the NHS instruments are the Patient Health Questionnaire (PHQ-9) and the Generalised Anxiety Disorder (GAD-7) (NHS, 2012). These instruments help practitioners to assess the severity of depression and anxiety. The Clinical Outcome in Routine Evaluation (CORE-OM) instrument assesses general wellbeing, problems/symptoms, functioning and risks.

Trauma and Stress

The Impact of Event Scale – Revised (IES-R) assess the presence of post traumatic stress (NHS, 2015).


The Dyadic Assessment Scale (DAS) helps to differentiates positive dyadic adjustment from distressed couples. It has a cut-off score where separation may be likely. There are four subscales: consensus, satisfaction, cohesion and affectional expression.

Gender Incongruence

The International Classification of Diseases 11th Revision (ICD-11) has taken a massive steps to de-pathologise transgender health by re-categorising gender incongruence as a sexual health condition (WHO, n.d.). Gender incongruence was never a disorder but ICD-10 and DSM-V had classified it as such which caused a lot of problems for transgender people being further stigmatised by the medical profession. Therefore the ‘Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults’ (GIDYQ-AA) is based on this old thinking of psychiatry. It doesn’t account for gender diversity and sees transgender as a move from male to female or from female to male. This excludes non-binary, agender and intersex experiences which don’t fit under this understanding. As the most frequented questionnaire on my website I believe it may has a value for some of the visitors. Here are two versions of this instruments: female assigned gender at birth / male assigned gender at birth

Personality Inventory and Anger Management

The Personality Inventory for DSM-V (PID-5) is an exhaustive instrument with 220 items and 25 sub-scales assessing “emerging measures” for further research and clinical evaluation (American Psychiatric Association, n.d.). The Anger Management Scale (AMS) assesses escalating strategies, negative attribution, self awareness and calming strategies which are contributing factors to anger management.
