Infant Behavior Questionnaire-Revised (IBQ-R; short form) was used to assess effortful control (12 items) and activity level (3 items). The IBQ-R measures early temperament-based inhibitory control,a key component of executive function as children mature. Scores range from 1 to 7, with higher scores indicating greater frequency of behaviors. IBQ-R scores were measured at baseline and then again at study completion (180 days post randomization). The scores were calculated as a change between two time points (the IBQ-R value at 180 days minus the IBQ-R value at baseline).

Bayley Scales of Infant and Toddler Development, third edition, (Bayley-III) is an instrument designed to measure the developmental functioning of infants and toddlers between the ages of 1 month and 42 months (age adjustments for prematurity are accommodated with the tool). It provides age specific composite scores for cognitive (91 items,score min 55 max 145), language (98 items, score min 47 max 153), and motor (138 items, score min 46 max 154) skills. For all scales, higher scores are better and lower scores indicate possible delay/deficit. Bayley-III scores were measured at baseline and then again at study completion (180 days post randomization). The scores were calculated as a change between two time points (the Bayley-III value at 180 days minus the Bayley-III value at baseline).

The following sleep characteristics were captured based on caregiver-report: nocturnal sleep duration (hours), daytime sleep duration (hours), total sleep duration within a 24-hour period (hours). Larger values represent more time spent in each type of sleep. BISQ scores were measured at baseline and then again at study completion (180 days post randomization). The scores were calculated as a change between two time points (the BISQ value at 180 days minus the BISQ value at baseline).

Changes in body composition from baseline to 6 months post-randomization (weight, recumbent length, head circumference, mid-upper arm circumference, triceps and subscapular skinfolds). These measurements were converted to z scores for corrected age based on Child Growth Standards from the World Health Organization. The z-score indicates the number of standard deviations away from the mean. A z score of 0 is equal to the mean of a reference population (children the same age and sex). Values less than 0 indicate values lower than the reference population, while values greater than 0 indicate values higher than the reference population.

Timeframe: 180 days post-randomization

Population: The number analyzed for the competence and ASD scales differs from the overall number analyzed due to missing data on these two scales.

BITSEA measures socioemotional development in toddlerhood. Scores were summed to provide competence (range: 0-22) and problem (range: 0-62) scores, respectively. The problem scale is further divided into subscales: externalizing (6 items; range: 0-12), internalizing (8 items; range: 0-16), and dysregulation (8 items; range: 0-16). Additionally, 14 items comprise a red flag scale (range: 0-28). Eight items from the competence and nine items from the problem subscales are indicative of behaviors often seen in children with ASD. Each of the 17 ASD items was dichotomized to illustrate the presence (1) (i.e., competence items absent, problem items present) or absence (0) (i.e., competence items present, problem items absent) of each ASD behavior. Items were then summed to derive an ASD score (range: 0-17). Higher competence scores represent better functioning, whereas higher problem (including the problem subscales), red flag, and ASD scores were indicative of poorer functioning.

The PDDST-II is a clinically derived, caregiver-completed screener to assist in differentiating an ASD diagnosis from other disorders in children with developmental concerns, including those born preterm. The PDDST-II comprised 14 yes/no items that indicate the presence (1) or absence (0) of developmental concerns. Items were summed (possible range: 0-14) and higher scores represented greater developmental concern.

Larger values represent more time spent in each type of sleep. BISQ scores were measured at baseline and then again at post-intervention follow-up (approximately 8 months after the trial ended).

Timeframe: Long-term effect (approximately 8 months) after intervention completion

Long-term (26-32 months of age) executive function outcomes. This will be evaluated using scores on the Behavior Rating Inventory of Executive Function - Preschool Version (BRIEF-P). The BRIEF-P yields five clinical scales, each measuring a different aspect of executive function: inhibit, shift, emotional control, working memory, and plan/organize. The clinical scales merge to create four broad indices of executive function: inhibitory self-control, flexibility, emergent metacognition, and global executive composite. A t-score of 50 is equal to the population mean with scores below 50 indicating better executive function, and scores above 50 indicating worse executive function for each reported aspect.

OTHER_PRE_SPECIFIED outcome

Timeframe: Long-term effect (approximately 8 months) after intervention completion

Long-term (26-32 months of age) outcomes. This will be evaluated using scores on the Communicative Development Inventory (CDI). On this measure, caregivers selected the number of words from a list of 100 common words that their child used. Scores reflect the total number of words, from the list of 100, that the child used.
