E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of the study is to determine whether low dose amitriptyline (10-20 mg nightly) in chronic insomnia coexisting with medical conditions is as effective as CBT-I in improving subjective sleep.
|

E.5 End points |
E.5.1 | Primary end point(s) |
The main objective of the study is to determine whether low dose amitriptyline (10-20 mg nightly) in chronic insomnia coexisting with medical conditions is as effective as CBT-I in improving subjective sleep. |
De belangrijkste studie-parameter is de gemiddelde subjectieve Insomnie Ernst score, gemeten met de Insomnia Severity index (ISI). Primair eindpunt is bij 12 weken. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Secondary objectives include (1) investigating the long-term efficacy of amitriptyline in comparison to CBT-I, (2) determining the effect on daytime symptoms and functioning, (3) determining whether the medication is well tolerated (safe) (4) identifying mediators and moderators of treatment outcome |
Secundaire uitkomstmaten betreffen slaapkwaliteit, gekwantificeerd als slaap efficiëntie en vragenlijsten omtrent klachten en functioneren overdag (vermoeidheid, emotionele klachten, fysiek functioneren, beperkingen in het functioneren). Mogelijke moderatoren zijn pijn, type insomnia, behandelvoorkeur, causale attributies omtrent insomnia, disfunctionele gedachten en houdingen ten aanzien van slap, pre slaap gerelateerde arousal. Tevens worden negatieve gebeurtenissen, en behandelevaluatie (bijwerkingen, withdrawal symptomen en therapietrouw) gemeten. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
10 assessments will take place: at baseline, at start treatment, 6, 12 and 14 weeks, and the responders during follow-up (i.e. reduction on ISI <8 until relapse) at 2, 4, 6 , 8 , 10 and 12 months post treatment. A one-week sleep diary is requested at start treatment,12 weeks, and 12 months post treatment. |
10 evaluaties zullen plaatsvinden: op de basislijn, voor de start van de behandeling, bij 3, 6, 12 en 14 weken na de start van de behandelingen. De responders tot terugval vervolgd worden op 2, 4, 6, 8, 10 en 12 maanden post behandeling. Een slaapdagboek van één week wordt ingevuld bij de start van de behandeling, bij 12 weken, en 12 maanden na behandeling. |
