Research Instruments

Research, Training & Educational Programs are all part of the package that IDRAAC offers to the Lebanese public in particular and to the Arab speaking public in general.
IDRAAC has worked since 1980 on adapting several internationally recognized instruments to the Arabic language for use in mental health research and practice.

Following is a list of the research instruments that IDRAAC has adapted to Arabic and has used in its research over the years, including ones for which IDRAAC has been designated as an official training center (CIDI training).

All these tools listed below are not to be used without authors’ permission.

The translation into Arabic is only used for research purposes. Any clinical use requires formal permission from the authors of that instrument.

AD8 Dementia Screening Interview

The AD8: The Washington University Dementia Screening Test, also known as “Eight-item Interview to Differentiate Aging and Dementia” (AD8), is a short and simple to use instrument that an informant or older adult can complete. The AD8 contains 8 items that test for memory, orientation, judgment, and function.

It is a 22-item questionnaire to measure the subjective burden of caregivers in five domains (general strain, isolation, disappointment, emotional involvement, and environment). Respondents rate the frequency with which items apply to them on a 4-point scale, ranging from "not at all" to "often".

Child Depression Inventory (CDI), (by M. Kovacs)

A self-rating scale designed to be used with children and adolescents who have Major Depression. It is useful as a screening tool for depression and it is sensitive to changes in the clinical condition. There is a child and a parent version.

Clinical Dementia Rating Scale (CDR)

The Clinical Dementia Rating or CDR is a numeric scale used to quantify the severity of symptoms of dementia. Using a structured-interview protocol developed by Charles Hughes, Leonard Berg, John C. Morris and other colleagues at Washington University School of Medicine, this scale assesses a person’s cognitive and functional performance in six areas: memory, orientation, judgment and problem solving, community affairs, home & hobbies, and personal care.

Composite International Diagnostic Interview (CIDI)

The World Mental Health WMH-CIDI is a comprehensive, fully-structured interview designed to be used by trained lay interviewers for the assessment of mental disorders according to the definitions and criteria of ICD-10 and DSM-IV. It is intended for use in epidemiological and cross-cultural studies as well as for clinical and research purposes. The diagnostic section of the interview is based on the World Health Organization's Composite International Diagnostic Interview (WHO CIDI, 1990).

    The WMH-CIDI allows the investigator to:
  • Measure the prevalence of mental disorders
  • Measure the severity of these disorders
  • Determine the burden of these disorders
  • Assess service use
  • Assess the use of medications in treating these disorders
  • Assess who is treated, who remains untreated, and what are the barriers to treatment

When choosing to become part of the WMH-CIDI community you are presented with a unique opportunity of administering the instrument in its PAPI (paper and pencil) form or in its computerized form [more commonly referred to as a Computer Assisted Personal Interviewing (CAPI)].

Cornell Scale for Depression in Dementia

The CSDD is a 19-item instrument specifically designed for the rating of symptoms of depression in demented patients. The severity of each item is rated according to three explicitly defined grades: absent, mild or intermittent, and severe.

Diagnostic Interview for Genetic Studies (DIGS)

The Diagnostic Interview for Genetic Studies (DIGS) was developed by the National Institute for Mental Health (NIMH) in the USA, for the specific field of genetic studies. DIGS is used to assess the phenotypes of most psychiatric disorders. A team of experts from IDRAAC (Lebanon) and Weill Cornell Medical College (Qatar) translated and adapted the DIGS 4.0 into Arabic as a first step towards an enhanced line of genetics research in the region. Special training is needed before using this instrument. For a sample of the Arabic DIGS please Click Here. For the full version of the Arabic DIGS please contact us at

Diagnostic Interview Schedule (DIS)

The DIS is a structured interview developed at Washington University at St. Louis (USA) and the National Institute of Mental Health (NIMH, USA). The DIS is designed to be used by lay interviewers in epidemiological studies. It provides diagnoses in mental health according to the Diagnostic and Statistical Manual of Mental Disorders (DSM, American Psychiatric Association). IDRAAC adapted the first version of DIS to Arabic in 1982, has trained people on its use and has used this instrument in several research projects.

Hypomania Checklist-32 (HCL) was developed by Angst et al., in 2005 to “identify hypomanic components in patients with major depressive disorder in order to help clinicians to diagnose Bipolar Disorder II and other Bipolar spectrum disorders”. The main 32 items- which requires a yes/no answer- specifically probe for behaviours, emotions and thoughts typically observed in hypomanic states (e.g. ‘I need less sleep’ or ‘I am less shy or inhibited’) and the questionnaire refers to ‘a period when [you] were in a “high” state’ (mania), in the last four months. The questionnaire also includes items about the duration of such ‘highs’, as well as the current and habitual mood.

War Events Questionnaire (WEQ), (by EG. Karam, R. Al- Atrash, S. Saliba, N. Melhem, D. Howard)

The WEQ covers a wide variety of war events. The list of specific war events included in the questionnaire represents events that occur frequently in war situations.
Part I inquires about the occurrence of specific war events like house damage, physical injury, kidnapping and business loss.
In Part II, events like displacement, water and electricity shortages, going to the shelter, etc.. that occur rather frequently and repeatedly for the same individual are inquired about. Since perception of war events is seen by many authors to be an important factor in the study of war stressors, the WEQ also assesses the subject’s perception of the war events they have been exposed to. To each war event inquired about in part I, the interviewee gives a score from 0 to 10, depending on how traumatic the event was perceived by that subject. Thus, every war event gets two numerical values, one pre-set and one given by the interviewee. To know more please refer to: Social Psychiatry & Psychiatric Epidemiology, 1999, Vol. 34(5): 265-274. EG. Karam, R. Al-Atrash, S. Saliba, N. Melhem, D. Howard.
