Primary |
Change in the Pittsburgh Sleep Quality Index (PSQI) total score |
The PSQI is a 9-item participant-reported measure that assesses sleep quality. Scores range from 0 to 21 points, with higher scores indicating poorer sleep quality. Scores = 5 are clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Primary |
Change in the Insomnia Severity Index (ISI) total score |
The ISI is a 7-item participant-reported measure that assesses insomnia symptoms. Scores range from 0 to 28 points (each item is rated 0-4), with higher scores indicating greater insomnia. Scores = 11 are clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Primary |
Change in actigraphic total sleep time (TST) |
Wrist actigraphy devices objectively assess TST, in minutes. TSTs < 360 min are considered clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Primary |
Change in actigraphic sleep efficiency (SE) |
Wrist actigraphy devices objectively assess SE as a % of time asleep while in bed. SEs < 85% are considered clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Primary |
Change in actigraphic sleep latency (SL) |
Wrist actigraphy devices objectively assess SL, in minutes. SLs > 30 min are considered clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Primary |
Change in actigraphic wake after sleep onset (WASO) |
Wrist actigraphy devices objectively assess WASO, in minutes. WASOs > 30 min are considered clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the Modified Fatigue Impact Scale (MFIS) total score |
The MFIS is a 21-item participant-reported measure that assesses how much fatigue impacts physical, cognitive, and psychosocial functioning. Scores range from 0 to 84 (each item is rated 0-4), with higher scores indicating a greater impact of fatigue. Scores = 38 are clinically significant. The scale has three subscales (Physical, 9 items; Cognitive, 10 items; and Psychosocial, 2 items). |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the Beck Depression Inventory - Fast Screen (BDI-FS) total score |
The BDI-FS is a 7-item participant-reported measure of depressive symptom severity. Scores range from 0 to 21 (each item rated 0-3), with higher scores indicating greater depressive symptom severity. Scores = 4 are clinically significant. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the MS Neuropsychological Screening Questionnaire (MSNQ) total score |
The MSNQ is a 15-item participant-reported measure of subjective cognitive dysfunction. Scores range from 0 to 60 (each item rated 0-4), with higher scores indicating greater perceived cognitive dysfunction. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the TestMyBrain Memorizing Words (MW) score |
TestMyBrain.org is an online platform that objectively assesses cognitive dysfunction. MW is a verbal paired associates test. Participants learn and memorize 25 word pairs and are asked to recall them after a delay. Higher scores indicate better verbal memory performance. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the TestMyBrain Memorizing Pictures (MP) score |
TestMyBrain.org is an online platform that objectively assesses cognitive dysfunction. MP is a visual paired associates test. Participants learn and memorize 24 pictures pairs and are asked to recall them after a delay. Higher scores indicate better visual memory performance. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the TestMyBrain Matching Shapes and Numbers (MSN) score |
TestMyBrain.org is an online platform that objectively assesses cognitive dysfunction. MSN is a speeded digit-symbol coding task. Participants use a key provided on the screen to quickly match 9 unique symbols with their correctly paired digits as quickly as possible. Higher scores indicate faster processing speed. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Change in the TestMyBrain Fast Choices (FC) score |
TestMyBrain.org is an online platform that objectively assesses cognitive dysfunction. FC is a choice reaction time test. Participants view arrows and quickly judge their direction. Higher scores indicate faster processing speed. |
Baseline (Week 1), Post-intervention (Week 6), and Follow-up (Week 12) |
|
Secondary |
Treatment Satisfaction Scale (TSS) total score (iSLEEPms group only) |
The TSS a 7-item participant-reported measure adapted from the Consumer Report Treatment Satisfaction Scale to assess satisfaction with iSLEEPms. The 7 items (each item rated 1 to 5) are averaged to calculate a total score, with higher scores indicating greater symptom improvement during the iSLEEPms program. |
Post-intervention (Week 6) |
|
Secondary |
iSLEEPms treatment adherence (iSLEEPMS group only) |
Treatment adherence will be assessed based on completion of each of the four weekly iSLEEPms modules, including completion of the online daily sleep diary form and weekly module. A total score will be determined based on the percentage of diary forms and weekly modules completed over four weeks. |
Post-intervention (Week 6) |
|
Secondary |
iSLEEPms treatment integrity (iSLEEPMS group only) |
Treatment integrity will be assessed based on coverage of coverage of 17 CBT-I elements, adapted from the Treatment Components Adherence Scale. A total score will be determined based on the percentage of elements covered over the four-week iSLEEPms intervention. |
Post-intervention (Weeks 6) |
