Primary Outcome Measures
NameTimeMethod
Proportion of patients who reached a +2 or +1 on at least one goalMonth 12
Proportion of total goals achievedMonth 12
Overall GAS scoreMonth 12

Goal Attainment Scaling (GAS) is a patient-centric clinician-reported outcome measure utilized to select and scale goals, with higher scores indicating greater goal attainment.

An overall GAS score utilizing all goals set by a patient at each time point of interest will be calculated.

Frequency of selection of category of physical activityBaseline

Categories of the goals selected from the goal inventory

Monthly average of daily step countFrom Baseline to Month 12

The monthly average of daily step count (recorded by physical tracker) will be calculated using the total steps recorded in a 30-day period, accounting for the number of compliant days in that period.

Monthly average of daily Metabolic equivalent of tasks (MET)From Baseline to Month 12

Estimated by the physical activity tracker

Monthly average of daily activity countFrom Baseline to Month 12

Activity count includes: time spent in x, y, and z axes, vector magnitude counts, estimated calories, wear time, time spent in locomotion and non-locomotion. Counts will be averaged across the month.

Monthly average of daily Moderate and Vigorous Physical Activity (MVPA)From Baseline to Month 12

Summarized from MET data with time spent in moderate intensity, and vigorous intensity physical activity

Monthly average of daily intensity gradientFrom Baseline to Month 12

The intensity gradient is a measure of activity intensity distribution that reflects the distribution of intensity of physical activity by modeling the relationship between intensity and time.

Monthly average of weekly intensity gradientFrom Baseline to Month 12
Secondary Outcome Measures
NameTimeMethod
Change in HAL ScoreFrom Baseline to Month 12

Hemophilia Activities List (HAL) is a 42-item questionnaire to access patient ability across 7 domains: lying down/ sitting/ kneeling/ standing (8 items), functions of the legs (9 items), functions of the arms (4 items), use of transportation (3 items), self-care (5 items), household tasks (6 items), and leisure activities (7 items). Patients rate each question on a Likert scale ranging from 1 (impossible) to 6 (never). Several items have a "not applicable" option as well. There is also a visual analog scale allowing patients to self-report an overall score. A normalized total score (sum of all normalized domains) ranges from 0 (the worst possible functional status) to 100 (the best possible functional status)

Change in school/work hours missed as assessed by WPAI+CIQ:HSFrom Baseline to Month 12

The Work Productivity and Activity Impairment plus Classroom Impairment Questions: Hemophilia Specific (WPAI + CIQ: HS) is a 9-item questionnaire assessing the effect of hemophilia on patients' ability to work and/or attend classes.

Change in PROMIS Pain intensity scoreFrom Baseline to Month 12

Patient-Reported Outcome Measurement Information System (PROMIS): assessment of pain over the prior 7-day period (2 of the 3 questions) and right now (1 of the 3 questions), with patients rating their pain on a scale of 0 (had no pain) to 5 (very severe). Total score ranges from 0 to 15 and a higher score indicates worst pain intensity.

Change in PROMIS pediatric Pain intensity scoreFrom Baseline to Month 12

Assessment of the average pain over the prior 7-day period, with patients rating their pain on a scale of 0 (no pain) to 10 (worst pain they can think of). A higher score indicates worst pain intensity.

Change in PedHAL ScoreFrom Baseline to Month 12

Pediatric Hemophilia Activities List (PedHAL) is a 53-item questionnaire to access patient functional ability across 7 domains: lying down/ sitting/ kneeling/ standing (10 items), functions of the legs (11 items), functions of the arms (6 items), use of transportation (3 items), self-care (9 items), household tasks (3 items), and leisure activities and sports (11 items). Patients rate each question on a Likert scale ranging from 1 (impossible) to 6 (never). Several items have a "not applicable" option as well. There is also a visual analog scale allowing patients to self-report an overall score. A normalized total score (sum of all normalized domains) ranges from 0 (the worst possible functional status) to 100 (the best possible functional status).

Monthly total and average of daily time spent in different intensity levelsFrom Baseline to Month 12

Physical activity intensity defined as sedentary behavior, light intensity, moderate intensity, and vigorous intensity,

Monthly average of daily median activity count overall among moderate activities and among vigorous activitiesFrom Baseline to Month 12

Daily median time spent in moderate and vigorous physical activity will be averaged across the month

Monthly average of weekly power law exponent alphaFrom Baseline to Month 12
Mean change in total and joint domain scores of HJHSFrom Baseline to 12 months

The Hemophilia Joint Health Score (HJHS) assesses 6 index joints (left and right elbows, knees and ankles) and a global gait. For each of the 6 joints, the following items are scored: swelling (scored 0-3), duration of swelling (0-1), muscle atrophy (0-2), crepitus on motion (0-2), flexion loss (0-3), extension loss (0-3), joint pain (0-2), and strength (0-4). The HJHS provides a total score (0-124 points with higher score indicating worse joint health), joint specific scores (0-20 points), and a global gait score (0-4 points).

Change in productivity as assessed by WPAI+CIQ:HSFrom Baseline to Month 12

The Work Productivity and Activity Impairment plus Classroom Impairment Questions: Hemophilia Specific (WPAI + CIQ: HS) is a 9-item questionnaire assessing the effect of hemophilia on patients' ability to perform regular daily activities.

Change in impact on other activities as assessed by WPAI+CIQ:HSFrom Baseline to 12 months

The Work Productivity and Activity Impairment plus Classroom Impairment Questions: Hemophilia Specific (WPAI + CIQ: HS) is a 9-item questionnaire assessing the effect of hemophilia on patients' ability to perform other activities.
