We report the trajectory of adaptive behavior from a prospective, longitudinal, natural history study.

We analyzed longitudinal Vineland Adaptive Behavior Scales, Second Edition domain-level standard scores and subdomain-level growth scale values (GSVs) obtained at baseline, 12 months, and 24 months. We assessed within-subject time effects and cross-sectional age effects using linear mixed effects models. This sample included 99 participants (baseline age = 8.83 ± 4.58 years). Within-subject standard scores decreased/remained constant for all domains: Communication (slope of within-subject mean-centered age = -0.33 [95% CI -1.08, 0.41]; p = 0.38), Socialization (-1.25 [-1.95, -0.56]; p < 0.001), and Daily Living Skills (-0.35 [-1.37, 0.67]; p = 0.50). However, subdomain GSVs showed within-subject growth across several categories. Receptive (5.26 [2.49, 8.02]; p < 0.001) and Written (2.79 [1.11, 4.47]; p = 0.001) Communication GSVs increased.

PMS is characterized by impaired adaptive behavior and slow, small gains in communication and daily living, but not socialization skills, as measured by subdomain GSVs.
