| Primary | Change from baseline in the Expressive Language Sampling (ELS) mean Number of Different Words (NDW) score | Baseline, End of Treatment/Week 16 | The ELS is collected from shared interactions around a wordless picture book involving the participant and the examiner. The primary outcome measure will be Number of Different Words (NDW) derived from transcripts of audiorecorded samples of spoken language taken from two sampling contexts (conversation and narration), according to procedures described by Abbeduto and colleagues (Abbeduto et al., 1995; Kover et al., 2012). Samples are collected pre- and post- treatment using different books on each occasion. The mean of NDW in conversation and NDW in narration will be computed, and statistically adjusted through analysis of covariance for differences in talkativeness as outlined in Conners et al., 2018. The mean NDW score ranges from 1 to infinite/unspecified. An increase (positive change) in score from baseline to follow-up indicates improvement. The greater the increase, the greater the improvement. |
| Secondary | Change from baseline in the FXS-normed Aberrant Behavior Checklist - Community Edition (ABC-C) | Baseline, Week 8, End of Treatment/Week 16 | The ABC-C is a 58-item caregiver-rated behavior scale used to examine treatment effects on challenging behaviors for individuals with FXS in the following domains: (1) irritability, agitation, crying; (2) lethargy, social withdrawal; (3) stereotypic behavior; (4) hyperactivity, noncompliance; and (5) inappropriate speech. Analysis will be performed utilizing the Sansone et al. (2012) FXS-normed ABC scoring measures. |
| Secondary | Improvement of symptoms in FXS using the Clinical Impression - Improvement (CGI-I) scale | Baseline, Week 8, End of Treatment/Week 16 | The CGI is a clinician-rated scale utilizing history from the caregiver and incorporating it into a clinical rating, first for severity, and then for clinical follow-up. The CGI-S will be used at the baseline assessment to judge symptom severity as 1 = Normal, not at all ill; 2 = Borderline ill; 3 = Mildly ill; 4 = Moderately ill; 5 = Markedly ill; 6 = Severely ill; and 7 = Among the most extremely ill. The CGI-I will be used at the Week 8 and End of Treatment/Week 16 visits to judge the change in clinical impression as 1 = Very Much Improved; 2 = Much Improved; 3 = Minimally Improved; 4 = No Change; 5 = Minimally Worse; 6 = Much Worse; and 7 = Very Much Worse. |
| Secondary | Change from baseline in the Visual Analog Scale (VAS) | Baseline, Week 8, End of Treatment/Week 16 | The VAS will be used to measure the severity of three specific behavioral symptoms targeted in this study: behavior problems, language abilities, and eating behavior. For each behavior the caregiver is instructed to mark their impression of the behavior at the baseline visit and again at the Week 8 and End of Treatment/Week 16 visits. The calculated distance in cm between the visit marks thereby demonstrates whether each behavior stayed the same, improved, or worsened during the study and by how much. The scale is from 0 cm (defined as "worst behavior") to 10 cm ("behavior not a problem"). |
| Secondary | Change from baseline in the Vineland Adaptive Behavior Scales-Third Edition (VABS-III) Adaptive Behavior Composite Score | Baseline, End of Treatment/Week 16 | The VABS-III is a caregiver survey interview that measures the personal and social skills of individuals from birth through adulthood. It was designed to assess handicapped and non-handicapped persons in their personal and social functioning and is appropriate for individuals of all ages. The Adaptive Behavior Composite (ABC) score is calculated from the caregiver responses using age-adjusted scoring tables. ABC scores range from 20 to 160 and indicate low (20-70), moderately low (70-85), adequate (85-115), moderately high (115-130), or high (130-160) overall adaptive functioning. |
| Secondary | Change from baseline in the Anxiety Depression and Mood Screen (ADAMS) overall score | Baseline, Week 8, End of Treatment/Week 16 | The CSHQ consists of a series of questions relating to the sleep habits of children. It will be completed by caregivers of all participants, regardless of participant age, at the baseline, Week 8, and End of Treatment/Week 16 visits. |
| Secondary | Change from baseline in the Swanson, Nolan and Pelham Questionnaire (SNAP-IV) overall score | Baseline, Week 8, End of Treatment/Week 16 | The SNAP-IV, based on DSM-V criteria for ADHD, is a caregiver-rated questionnaire that effectively identifies those with and without ADHD and accurately predicts presentation specifier (inattention, hyperactivity/impulsivity, and combined). Its psychometric properties and clinical utility have been demonstrated in multiple studies since its introduction in 2001, and it has been found to be reliable and well validated with normative data from both parents and teachers. It will be completed by caregivers of all participants at baseline, Week 8, and End of Treatment/Week 16. |
| Secondary | Change from baseline in the Pediatric Quality of Life Questionnaire (PedsQL) Parent Proxy overall score | Baseline, Week 8, End of Treatment/Week 16 | The PedsQL Parent Proxy consists of a series of questions relating to a child's quality of life and is administered to the caregiver of the participant. The parent proxy module designed for children 8-12 years of age will be administered to the caregivers of all participants, regardless of participant age, because the questions therein are most appropriate for the overall study population's cognitive age and ability. It will be completed at the baseline, Week 8, and End of Treatment/Week 16 visits. For any participants not in school, questions pertaining to "school" will be replaced with references to "work" or other activities in their life. |
| Secondary | Change from baseline in the EuroQol-5D (EQ-5D) overall score | Baseline, Week 8, End of Treatment/Week 16 | This is a standardized instrument developed by the EuroQol Group as a measure of health-related quality of life that can be used in a wide range of health conditions and treatments. The EQ-5D consists of a descriptive system and the EQ VAS. We will use the EQ-5D-Y, EQ-5D-Y parent proxy, EQ-5D-3L, and EQ-5D-3L parent proxy depending on the participants age and ability. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale. This can be used as a quantitative measure of health outcome that reflects the patient's own judgement. The scores on these five dimensions can be presented as a health profile or can be converted to a single summary index number (utility) reflecting preferability compared to other health profiles. |
| Secondary | Change from baseline in the Care Related Quality of Life (CarerQoL) overall score | Baseline, Week 8, End of Treatment/Week 16 | The CarerQol was designed to measure and value the impact of providing informal care on carers. It combines a subjective burden measure that provides a comprehensive description of the caregiving situation (CarerQol-7D) with a valuation of informal care in terms of well-being (CarerQol-VAS). |
| Secondary | Change from baseline in The Memory Game | Baseline, End of Treatment/Week 16 | This is an online test developed in the Bolduc Laboratory done on a tablet at home. Participants are asked to remember association between sets of pictures. The test has been done in typical development and developmental delay for participants 4 years and up. The test has an online consent form followed by a short demonstration video. The participants are then shown pairs of pictures they must remember. Testing is performed right after the presentation and again 24 hours later. For the 24 hours testing, the participants/caregivers will receive an email reminder and will be invited to login to the Memory Game site to perform the association test this time without being shown the demonstration video. The testing takes about 20 minutes the first day and 7 minutes the second day. It will be completed before treatment starts and after treatment ends. |
| Secondary | Change from baseline in the Child Sleep Habits Questionnaire (CSHQ) overall score | Baseline, Week 8, End of Treatment/Week 16 | The CSHQ consists of a series of questions relating to the sleep habits of children. It will be completed by caregivers of all participants, regardless of participant age, at the baseline, Week 8, and End of Treatment/Week 16 visits. |
| Secondary | Change from baseline in the NIH Toolbox Picture Sequence Memory Test | Baseline, End of Treatment/Week 16 | This test involves recalling increasingly lengthy series of illustrated objects and activities around different themes (e.g., "playing at the park," "working on the farm") that are presented in a particular order on the screen. Encoding, storage, and retrieval of episodic memories depend on a neural network including the temporal lobe (especially the hippocampus), the prefrontal cortex, and limbic/temporal association areas. Patients with FXS perform approximately two standard deviations below normal on PSM, which demonstrates good feasibility, test-retest reliability in both healthy children and those with ID; and moderate correlation with FSIQ. |
| Secondary | Change from baseline in the NIH Toolbox Flanker Inhibitory Control and Attention Test | Baseline, End of Treatment/Week 16 | Flanker is a measure of inhibition and visual attention. On each trial, a central directional target is flanked by similar stimuli on the left and right. The participant chooses the direction of the central stimulus. On congruent trials, the flankers face the same direction as the target. On incongruent trials, they face the opposite direction. Patients with FXS demonstrate profound deficits on Flanker, performing about 7 standard deviations below normal, and significantly worse than IQ-matched controls with Down syndrome. This test demonstrates excellent test-retest reliability and correlates significantly with FSIQ and dialing functioning in children and adolescents with ID. |
| Secondary | Change from baseline in the NIH Toolbox Dimensional Change Card Sort Test | Baseline, End of Treatment/Week 16 | This is a measure of cognitive flexibility. Two target pictures are presented that vary along two dimensions (i.e., shape and color). Participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). "Switch" trials are also employed, in which the participant must change the dimension being matched. It demonstrates good test-retest reliability and correlates well with FSIQ in children and adolescents with ID, including FXS . |
| Secondary | Change from baseline in the NIH Toolbox List Sorting Working Memory Test | Baseline, End of Treatment/Week 16 | This test requires immediate recall and sequencing of different visually and orally presented stimuli. Pictures of different foods and animals are displayed with accompanying audio recording and written text (e.g., "elephant"), and the participant is asked to state the items in size order from smallest to largest, first within a single dimension (either animals or foods, called 1-List) and then on 2 dimensions (foods, then animals, called 2-List). The raw score is the number of items recalled and sequenced correctly. |
| Secondary | Change from baseline in the NIH Toolbox Pattern Comparison Processing Speed Test | Baseline, End of Treatment/Week 16 | This test measures speed of processing by asking participants to discern whether two side-by-side pictures are the same or not the same by touching "yes" or "no" (or a happy or frowning face for lower mental age). Participants' raw score is the number of items correct in a 90-second period. The items are designed to be simple to distinguish. |
| Secondary | Change from baseline in the NIH Toolbox Oral Reading Recognition Test | Baseline, End of Treatment/Week 16 | The participant is asked to read and pronounce letters and words as accurately as possible. The test administrator scores them as right or wrong. The items are administered by computer adaptive testing (CAT; continuously adapted depending on performance), and participant responses are scored by the examiner. For the youngest children, the initial items require identification of letters (as opposed to symbols) and identification of a specific letter in an array of 4 symbols. A theta score is calculated for this test. |
| Secondary | Change from baseline in the NIH Toolbox Picture Vocabulary Test | Baseline, End of Treatment/Week 16 | This measure of receptive vocabulary is administered in a CAT format. The respondent is presented with an audio recording of a word and four photographs on the screen and is asked to select the picture that most closely matches the meaning of the word. A theta score is calculated for this test. |
| Secondary | Change from baseline in the NIH Toolbox Speeded Matching Test | Baseline, End of Treatment/Week 16 | This test measures speed of processing by asking participants to discern whether four side-by-side pictures match the target image at the top of the screen. The items are presented one group at a time on the iPad screen, and the participant is given 119.999 seconds of actual presentation time (excluding transitions between items) to respond to as many items as possible (up to a maximum of 130). The items are designed to be simple so as to most purely measure processing speed. Speeded Matching gives a raw score, which is the number of items the participant correctly responds to (up to 130) in 119.999 seconds. |
