Psychometric Instruments: What are they?

Psychometric Instruments: What are they?

Psychometric instruments are often used in the NHS, the voluntary sector and in research to assess therapeutic effectiveness. Clients are usually filling in paper forms in regular intervals to see if therapy is helping. I digitalised some of these forms as many people use the internet as a starting point in their healing journey. All these psychometric instruments are based on self reported data which means they represent a snapshot of how the person felt in that moment of filling them in. Psychometric instruments are not a diagnosis, but are often used as a tool in addition to other diagnostic assessment methods.

Depression, Anxiety and Post-Traumatic Stress

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

Gender Dysphoria/Gender Incongruence

It is important to note that 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. Nonetheless, I learnt that some people found this questionnaire useful as a starting point. Therefore 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.
