About the HMS

The Homicidality Modifiers Scale (HMS) assesses factors that can influence some domains of homicidality.  It covers the domains of:

  1. impulsive homicidality
  2. hopelessness
  3. loss of enjoyment
  4. overwhelmed feeling

For each domain covered, it assesses:

  1. the severity of each domain
  2. the ability to experience / resist the domain
  3. the loss of desire to experience / resist the domain
  4. how much memories impacted the domain
  5. how much events outside the patient’s control impacted the domain
  6. how much events within the patient’s control impacted the domain

Use to Clinicians

The answers to items 4 through 6 above provide the clinician with information about critical target domains. This helps the clinician to understand and to assist the patient in coping with these memories and events. The HMS sometimes provided an early warning sign of impending worsening of homicidality before it became apparent in other ways. This was particularly true of question 3 – “the loss of desire to hold back the impulse to plan or to act in any way to kill someone”. We suspect that the change in the score on this question may consistently precede other changes in homicidality, during deterioration in a subject with Impulse Attack Homicidality Disorder (as is true in Impulse Attack Suicidality Disorder). Question 3 also lagged behind improvement in other areas and was one of the last questions in that domain to fully resolve.

The HMS may be particularly helpful in assessing impulsive homicidality and hopelessness in a way that is very sensitive to change and may provide an early warning sign of impending worsening of homicidality before it becomes apparent in other ways.
