Group/Cohort Intervention/treatment
Cases
Women referred to two academic centres for the diagnosis and treatment of endometriosis.
 Other: Pittsburgh Sleep Quality Index.
Pittsburgh Sleep Quality Index is an effective instrument used to measure the quality and patterns of sleep of patients. It allows evaluating "poor" from "good" sleep by assessing seven domains. A total score ≤ 5 indicated good sleep quality while a total score > 5 was indicated poor sleep quality.

Other: Epworth sleepiness scale.
Epworth sleepiness scale is an 8-item questionnaire developed to measure average daytime sleepiness. A total score ≥ 10 indicates excessive daytime sleepiness.

Other: Insomnia Severity Index.
Insomnia Severity Index is a 7-item questionnaire developed to measure insomnia. A total score between 0 and 7 correspond to not clinically significant insomnia, between 8 and 14 to subthreshold insomnia, between 15 and 21 to clinical insomnia (moderate), between 22 and 28 to clinical insomnia (severe).

Other: The Endometriosis Health Profile.
The Endometriosis Health Profile is a patient generated instrument that evaluates disease-specific health-related quality of life in patients with endometriosis. The questionnaire is administrable to all patients with endometriosis and it consists in 30 items divided in 5 domains (pain, control and powerlessness, emotional well-being, social support and self-image). Each scale for each domain is comprised between 0 (indicating the best health status) and 100 (indicating the worst health status).
Controls
Women referred to our Institutions because of routine gynaecologic consultations.
 Other: Pittsburgh Sleep Quality Index.
Pittsburgh Sleep Quality Index is an effective instrument used to measure the quality and patterns of sleep of patients. It allows evaluating "poor" from "good" sleep by assessing seven domains. A total score ≤ 5 indicated good sleep quality while a total score > 5 was indicated poor sleep quality.

Other: Epworth sleepiness scale.
Epworth sleepiness scale is an 8-item questionnaire developed to measure average daytime sleepiness. A total score ≥ 10 indicates excessive daytime sleepiness.

Other: Insomnia Severity Index.
Insomnia Severity Index is a 7-item questionnaire developed to measure insomnia. A total score between 0 and 7 correspond to not clinically significant insomnia, between 8 and 14 to subthreshold insomnia, between 15 and 21 to clinical insomnia (moderate), between 22 and 28 to clinical insomnia (severe).

Primary Outcome Measures :
  1. Quality of sleep. [ Time Frame: Cases were administered and fulfilled the questionnaires at the moment of being scheduled for surgery (3-4 months before the operation). Controls were administered and fulfilled the questionnaires after routine gynaecologic consultation. ]
    Quality of sleep was assessed by using the Pittsburgh Sleep Quality Index.


Secondary Outcome Measures :
  1. Average daytime sleepiness. [ Time Frame: Cases were administered and fulfilled the questionnaires at the moment of being scheduled for surgery (3-4 months before the operation). Controls were administered and fulfilled the questionnaires after routine gynaecologic consultation. ]
    Average daytime sleepiness was assessed by using the Epworth sleepiness scale.

  2. Insomnia. [ Time Frame: Cases were administered and fulfilled the questionnaires at the moment of being scheduled for surgery (3-4 months before the operation). Controls were administered and fulfilled the questionnaires after routine gynaecologic consultation. ]
