Mental health
Why mental health?
Mental health problems are classed as a ‘specific condition’ outcome measure and are very common among people with substance misuse disorders. Questionnaires are helpful pointers to comorbidity and useful for monitoring symptom severity. It is, therefore, suggested that mental health measures are used to supplement the core addiction outcome measures. The recommended scales, built into Take-a-Test, are…
For depression and anxiety the PHQ9 and GAD7
For post traumatic stress disorder the PCL
For psychosis the PB16
For emotional over expression the BPC
Patient Health Questionnaire - PHQ9 and Generalised Anxiety Disorder - GAD7
Depression and anxiety are commonly associated with addiction problems and they so often go together that it is convenient to have companion scales. Caution interpreting scores with substance dependence. Popular measures in both primary care and specialist services. The diagnosis of depression or anxiety must be confirmed by qualified mental health professional.
Timeframe :: The last 14 days
Completion time :: Brief.
PHQ9 Scoring :: Each item is scored on a four point scale: 0= 'not at all' 1= 'several days' 2= 'more than half the days' 3= 'nearly everyday'. PHQ9 total scores range from 0 to 27
Cut-off score :: Higher scores reflect a greater symptom severity: 0 to 9 minimal symptoms; 10 to 14 minor depressive symptoms; 15 to 19 moderate severity; 20 to 27 severe depression. Scoring for a tentative diagnosis is more complicated and various methods have been suggested of which a requirement for at least five items to score ≥2 is the simplest.
GAD7 Scoring :: Each item is scored on a four point scale: 0= 'not at all' 1= 'several days' 2= 'more than half the days' 3= 'nearly everyday'. GAD-7 total scores range from 0 to 21
Cut-off score :: Higher scores reflect a greater symptom severity: 0 to 5 minimal symptoms; 6 to 10 mild severity; 11 to 15 moderately severe anxiety; 15 to 21 severe anxiety
