Study to Validate the Questionnaire Called IDSIQ™ in Patients With Insomnia Disorder

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03056053
Recruitment Status : Completed
First Posted : February 17, 2017
Last Update Posted : July 24, 2019
Information provided by (Responsible Party):
Idorsia Pharmaceuticals Ltd.

Brief Summary:
The main study objective is to assess the content validity and the psychometric characteristics of the Insomnia Daytime Symptoms and Impacts Questionnaire™ (IDSIQ™).

Condition or disease Intervention/treatment Phase
Insomnia Disorder Drug: Zolpidem Phase 2

Detailed Description:

Zolpidem will be used as an active intervention to assess the sensitivity to change of IDSIQ™ in patients suffering from insomnia disorder.

IDSIQ™ will be administered during the screening period (within 14 days before enrollment in the study) and the treatment period (from Day 1 to Day 14). End of study (phone call) will take place 30-37 days after the end-of-treatment.

Arm Intervention/treatment
Commercially available zolpidem (5 or 10 mg) will be administered orally once daily during the treatment period (Day 1 to Day 14) following prescribing information from each country participating in this study
Drug: Zolpidem
Commercially available tablets of zolpidem (5 or 10 mg) for oral use
Other Names:
  • Ambien
  • Zolpidem generics
  • Stilnox

Primary Outcome Measures :
  1. Content validity of the IDSIQ™: scoring of items into domains [ Time Frame: During the screening period, i.e. within 14 days before Day 1 ]
    Content validity will be based on the combination of qualitative and statistical methods in order to generate a scoring algorithm

Secondary Outcome Measures :
  1. Psychometric validitiy of the IDSIQ™: Internal reliability [ Time Frame: During the screening period, i.e. within 14 days before Day 1 ]
    Internal consistency reliability assesses the extent to which the items correlate which each other within their domain and it is evaluated by correlation scores

  2. Psychometric validitiy of the IDSIQ™: Test-retest reliability [ Time Frame: During the screening period, i.e. within 14 days before Day 1 ]
    Test-retest reliability assesses the reproducibility of the domain scores during a specific time period of stable condition and it is evaluated by intraclass correlation coefficients

  3. Psychometric validitiy of the IDSIQ™: sensitivity to change [ Time Frame: At Week 1 and Week 2 ]
    Changes in the IDSIQ domain scores after 2 weeks of treatment with zolpidem compared to baseline (before zolpidem administration)
