Background: Rett syndrome (RTT) is a severe neurodevelopmental disorder characterized by regression of language and motor skills, cognitive impairment, and frequent seizures. Although the diagnostic criteria focus on communication, motor impairments, and hand stereotypies, behavioral abnormalities are a prevalent and disabling component of the RTT phenotype. Among these problematic behaviors, anxiety is a prominent symptom. While the introduction of the Rett Syndrome Behavioral Questionnaire (RSBQ) represented a major advancement in the field, no systematic characterization of anxious behavior using the RSBQ or other standardized measures has been reported. Methods: This study examined the profiles of anxious behavior in a sample of 74 girls with RTT, with a focus on identifying the instrument with the best psychometric properties in this population. The parent-rated RSBQ, Anxiety, Depression, and Mood Scale (ADAMS), and Aberrant Behavior Checklist-Community (ABC-C), two instruments previously employed in children with neurodevelopmental disorders, were analyzed in terms of score profiles, relationship with age and clinical severity, reliability, concurrent validity, and functional implications. The latter were determined by regression analyses with the Vineland Adaptive Behavior Scales-Second Edition (Vineland-II) and the Child Health Questionnaire (CHQ), a quality of life measure validated in RTT. Results: We found that scores on anxiety subscales were intermediate in range with respect to other behavioral constructs measured by the RSBQ, ADAMS, and ABC-C. Age did not affect scores, and severity of general anxiety was inversely correlated with clinical severity. We demonstrated that the internal consistency of the anxiety-related subscales were among the highest. Test-retest and intra-rater reliability was superior for the ADAMS subscales. Convergent and discriminant validity were measured by inter-scale correlations, which showed the best profile for the social anxiety subscales. Of these, only the ADAMS Social Avoidance showed correlation with quality of life. Conclusions: We conclude that anxiety-like behavior is a prominent component of RTT's behavioral phenotype, which affects predominantly children with less severe neurologic impairment and has functional consequences. Based on available data on standardized instruments, the ADAMS and in particular its Social Avoidance subscale has the best psychometric properties and functional correlates that make it suitable for clinical and research

Abstract
Medium- and long-term outcomes have been collected and described among survivors of neonatal intensive care units for decades, for a number of purposes: (1) quality control within units, (2) comparisons of outcomes between NICUs, (3) clinical trials (whether an intervention improves outcomes), (4) end-of-life decision-making, (5) to better understand the effects of neonatal conditions and/or interventions on organs and/or long-term health, and finally (6) to better prepare parents for the future. However, the outcomes evaluated have been selected by investigators, based on feasibility, availability, cost, stability, and on what investigators consider to be important. Many of the routinely measured outcomes have major limitations: they may not correlate well with long-term difficulties, they may artificially divide continuous outcomes into dichotomous ones, and may have no clear relationship with quality of life and functioning of children and their families. Several investigations, such as routine term cerebral resonance imaging for preterm infants, have also not yet been shown to improve the outcome of children nor their families. In this article, the most common variables used in neonatology as well as some variables which are rarely measured but may be of equal importance for families are presented. The manner in which these outcomes are communicated to families will be examined, as well as recommendations to optimize communication with parents.
