Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Circadin melatonin 2mg prolonged release tablet is be taken orally after food and 1-2 hours prior to going to bed. Participants will be required to consume each of the respective treatments for a total of 8 weeks. Treatment intervention will commence at week 3 after the baseline run in period. As this a crossover study, the active melatonin treatment may be administered at either the first or second treatment intervention with each intervention 4 weeks in duration. The frist treatment intervention will commence at week 3 and end at week 6, with the second treatment intervention commencing at week 7 and finishing at week 10.
Intervention code [1] 266797 0
Treatment: Drugs
Comparator / control treatment
The control formulation matched active treatment for appearance and size consisting of Mannitol (106mg), Acacia (11mg) and Pure icing sugar (106mg). Both treatments were encapsulated in identical two-piece gelatin capsules and dispensed in identical containers, containing 30 capsules.
Both the active and placebo treatment was taken orally and 1-2 hours prior to habitual bedtime. Participants were directed to consume treatment for a total of eight weeks. Treatment intervention will commence at week 3 after the baseline run-in period. As this a crossover study, the placebo treatment may be administered at either the first or second treatment intervention with each intervention period four weeks in duration. The first treatment intervention will commence at week 3 and will end at week 6, with the second treatment intervention commencing at week 7 and finishing at week 10.

Outcomes
Primary outcome [1] 268985 0
Sleep onset latency
Timepoint [1] 268985 0
Mean sleep onset latency (minutes) will be measured continuously throughout the trial and over the 10 week period via Actigraphy. Sleep onset latency will be averaged over the baseline period and after each intervention period, respectively.
Primary outcome [2] 297319 0
Sleep quality: Sleep quality will be determined by global scores from the Pittsburgh sleep quality index (PSQI) questionnaire. The PSQI requires participants to subjectively rate their sleep quality in the previous month and will be used to determine treatment efficacy.
Timepoint [2] 297319 0
Sleep quality will be assessed pre and post baseline, and at the end of each treatment period. Consistent with other measures, sleep quality will be first assessed at baseline (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [1] 276753 0
Depression and Anxiety will be assessed with the use of paper and pen Hospital Anxiety and Depression Scale (HADS).
Timepoint [1] 276753 0
Depression and Anxiety will be assessed at four time points. The first takes place on their baseline assessment (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [2] 276754 0
General health and well being will be assessed with the use of a papper and pen questionnaire namely the SF-36 Health Related Quality of Life Questionnaire (SF-36).
Timepoint [2] 276754 0
General health and Well being will be assessed at four time points. The first takes place on their baseline assessment (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).
Secondary outcome [3] 320715 0
Mean sleep efficiency (%) determined by actigraphy.
Timepoint [3] 320715 0
Mean sleep efficiency (%): Sleep efficiency will be collected during baseline and throughout each treatment period. Sleep efficiency will be averaged over the baseline period and after each intervention period, respectively.
Secondary outcome [4] 320716 0
Daytime sleepiness as measured by the Epworth Sleepiness Scale (ESS)
Timepoint [4] 320716 0
ESS scores will be collected pre and post baseline and at the end of each treatment intervention, respectively. Consistent with other measures, ESS scores will be first assessed at baseline (week 0). The second takes place at the end of the baseline run-in period (week 2). The third at the end of treatment one (Week 6). The fourth at the end of treatment two (week 10).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Rehabilitation physicians and allied health staff will be responsible for approaching and informing ABI participants with sleep disturbance of the study. All participants will need to seek approval from their treating rehabilitation physician in order to participate in the study. Suitable candidates will be referred to a research assistance to determine study eligibility. Individuals meeting preliminary eligibility will be referred for a sleep physician consultation to further determine eligibility. Individuals meeting eligibility criteria will be encouraged to discuss participation with family, friends and other doctors not involved in the study before consenting.
The rehabilitation physician will be responsible for writing the treatment scripts (i.e., melatonin and placebo), but is blinded to treatment. Treatment randomization will be computer generated and recorded by the pharmacist not involved or associated with the study, with randomization sealed in opaque envelopes. Each envelope will indicate the order of treatment and the pharmacist not associated with the study will allocate treatment accordingly.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization was conducted by a researcher independent of the study, not involved with recruitment, testing or analysis. Block randomization was used (block size of 4) and six possible balanced permutations for assignment to the two conditions were each assigned an integer from one to six. Treatment conditions were assigned and sealed in an envelope ("M" for Melatonin first and "P" Placebo first). Participant codes were sequentially allocated as participants enrolled and treatments were dispensed by a pharmacist not affiliated with the study. Participants were randomized to receive melatonin or placebo treatment first at the end of the baseline period.
