Changes in Social Responsiveness Scale-2 (SRS-2) score
Lasso di tempo: From baseline to end of study (6 months)
|
Changes in the SRS-2 score in the L. reuteri group compared to the placebo group. The SRS-2 is a 65-item questionnaire, with higher scores indicating greater social impairment and severity of autism-related traits. |

Change in Autism Diagnostic Observation Schedule, 2nd Ed (ADOS-2) Calibrated Severity Score (CSS) for Social Affect
Lasso di tempo: From baseline to end of study (6 months)
|
Change in ADOS-2 CSS for Social Affect in the L. reuteri group compared to the placebo group. ADOS-2 is a semi-structured, standardized assessment that observes social interaction, communication, play, and restricted or repetitive behaviors across five modules tailored to age and language level. Higher scores indicate a higher level of autism-related behaviors. |
From baseline to end of study (6 months)
|
|
Change in total Autism Diagnostic Observation Schedule, 2nd Ed (ADOS-2) score
Lasso di tempo: From baseline to end of study (6 months)
|
Change in total ADOS-2 score in the L. reuteri group compared to the placebo group. ADOS-2 is a semi-structured, standardized assessment that observes social interaction, communication, play, and restricted or repetitive behaviors across five modules tailored to age and language level. Higher scores indicate a higher level of autism-related behaviors. |
From baseline to end of study (6 months)
|
|
Change in GI symptoms
Lasso di tempo: From baseline to end fo study (6 months)
|
Change in GI symptoms, assessed by the 6 item Gastrointestinal Severity Index (6-GSI) in the L. reuteri group compared to the placebo group. 6-GSI is a six item questionnaire with total score 0-12 with higher scores indicating worse outcome. |
From baseline to end fo study (6 months)
|
|
Change in ABAS-2 score
Lasso di tempo: From baseline to end fo study (6 months)
|
Change in adaptive behaviour, assessed by the Adaptive Behavior Assessment System, Second Edition (ABAS-2) in the L. reuteri group compared to the placebo group. ABAS-2 is a 4-point rating scale with the scoring system divided into skill area scores (range 1 to 19), domain scores (range 40 to 160) and general adaptive composite (40 to 150). A higher score indicates a better outcome. |
From baseline to end fo study (6 months)

Change in Family Quality of Life
Lasso di tempo: From baseline to end fo study (6 months)
|
Change in family Quality of Life (QoL), assessed by the Pediatric Quality of Life Inventory™ Family Impact Module (PedsQL™ Family Impact Module), in the L. reuteri group compared to the placebo group. The range of the total score is 0-100 with a higher score indicating a better outcome. |
From baseline to end fo study (6 months)
|
|
Change in quality of sleep
Lasso di tempo: From baseline to end of study (6 months)
|
Change in sleep quality, assessed by the Children's Sleep Habits Questionnaire, in the L. reuteri group compared to placebo. The CSHQ is scored on 33 of 52 items, using a 1-3 scale, with total score range 33-99. A higher score indicates worse outcome and the cut-off of a total score of 41 or higher indicating potential sleep problems. |
From baseline to end of study (6 months)
|
|
Impact of dietary habits
Lasso di tempo: At baseline and end of study (6 months)
|
Impact of dietary habits, assessed by a Food Frequency Questionnaire (FFQ), on the gut microbiota profile and effect of the L. reuteri intervention. |
At baseline and end of study (6 months)
|
|
Changes in gut microbiota structure and composition
Lasso di tempo: Baseline, 3 and 6 months
|
Changes in the gut microbiota structure and composition and the effect of the L. reuteri intervention, assessed by metagenomic analysis of fecal samples |
Baseline, 3 and 6 months
