Daily living skills scale: Development and preliminary validation of a new, open-source assessment of daily living skills.

Autistic individuals and individuals with a range of other neurodevelopmental conditions (NDD) often present with lower levels of daily living skills (DLS) when compared to their neurotypical peers. Importantly, lower levels of DLS have been linked to a range of negative outcomes, including lower rates of post-secondary education, lower employment rates, and higher daily support needs across autism and NDD. However, there are currently no open-source informant-reported instruments for capturing key aspects of DLS. This study describes the development, refinement, and initial psychometric evaluation of a new, relatively brief (53-item). Daily Living Skills Scale (DLSS) in a sample of 1,361 children aged 2-17 years, Confirmatory Factor Analysis demonstrated an excellent fit of unidimensional model to the data (CFI = 0.953, TLI = 0.951, RMSEA = 0.073 [95% CI: 0.071-0.074]). The single-factor CFA model showed evidence of measurement invariance of factor loadings, thresholds, and residual variance (strict invariance) across sex, age, race, and ethnicity. Model reliability and internal consistency were excellent (ω = 0.98; α = 0.97). Conditional reliability estimates indicated very good reliability (= 0.80) for the total DLS scale from very low (θ = -4.2) to high (θ = +2.4) scores. Conceptually derived self-care, homecare, and community participation subscales also showed strong reliability and internal consistency. With further replication, the EFS has excellent potential for wide adoption across research and clinical contexts.

A systematic review of functional analysis in pediatric feeding disorders.

We conducted a systematic review of the functional analysis of inappropriate mealtime behavior in peer-reviewed studies in PsycINFO, ERIC, PubMed, and the Journal of Applied Behavior Analysis between 2000-2016. We identified 18 studies involving 86 functional analyses. We coded descriptive data and calculated summary statistics in addition to conducting a quality appraisal of the literature. We identified escape, exclusively or in part, as the maintaining reinforcer for inappropriate mealtime behavior in 92% of cases. Results indicate that differentiated functional analyses of inappropriate mealtime behavior can be obtained, and outcomes are consistent with etiological theories of food refusal behavior. We discuss procedural differences across studies as well as directions for future research.
