DUAL DIAGNOSIS

Mentally ill chemical abusers or substance-abusing mentally ill persons2

DUAL DIAGNOSIS: The term “dual diagnosis” denotes the co-occurrence of substance abuse and severe mental illness.4

SUBSTANCE ABUSE: It refers to substance use disorders, which include abuse and dependence. 4

SEVERE MENTAL ILLNESS: It refers to long term psychiatric disorders, such as schizophrenia, that are associated with disability and that fall within the traditional purview of public mental health systems.4

In many ways dual diagnosis is an unfortunate misnomer2.

  • Because the individuals in this group (having dual diagnosis) are heterogeneous (It includes individuals with less disabling mental illnesses such as anxiety disorders, those with different severe illnesses such as schizophrenia and bipolar disorder, and those with either substance abuse or substance dependence) and tend to have multiple impairments (interacting disabilities, psychosocial problems, and disadvantages) rather than just two illnesses.4,2
  • There are other dual diagnosis populations, such as those with mental illness and developmental disabilities.

Nevertheless, the term dual diagnosis is a standard usage.2

NEGATIVE OUTCOMES OF DUAL DIAGNOSIS

Dual diagnosis is associated with a variety of negative outcomes, including:

  • higher rates of relapse 4
  • hospitalization7 and re-hospitalization2
  • violence and disruptive behavior and violence2, 8
  • incarceration 9
  • homelessness 10
  • serious infections such as HIV and hepatitis 11
  • familial problems2
  • decreased functional status2
  • medication noncompliance2

PREVALENCE

Experts have written, in effect, that dual diagnosis is an expectation, not an exception

It is now estimated that 60 to 90 percent of people seeking treatment at a mental health facility or a substance abuse facility facilities have dual disorders1

Whereas, another study has established that (about) 50 percent of individuals with severe mental disorders are affected by substance abuse 5

TREATMENT

One of the major difficulties in treating dual diagnosis is in engaging the patient in treatment. 13

  • SEPARATE SERVICES V/S INTEGRATED TREATMENT PROGRAMS: Current research also indicates that traditional, separate services for persons with dual disorders are ineffective and that integrated treatment programs that combine mental health and substance abuse interventions offer promise. 2,3
  • INTEGRATED TREATMENT: it means that the same clinicians or teams of clinicians, working in one setting, provide appropriate mental health and substance abuse interventions in a coordinated fashion4.
  • FAMILY INTERVENTIONS: address understanding and learning to cope with two inter-acting illnesses4.
  • MOTIVATIONAL INTERVENTIONS: involve helping the individual identify his or her own goals. They need to develop skills and supports to control symptoms and to pursue an abstinent lifestyle4.
  • COUNSELING: Effective programs provide some form of counseling that promotes cognitive and behavioral skills at this stage. 4
