“…Service user and service provider lists can be untrustworthy and problematic for audits, due to incomplete registers, inconsistency in the uptake to these registers, and variation in the documentation of the services provided [ 2 ]. We have previously highlighted the difficulties associated with obtaining a non-biased sample of children with ASD because of the lack of a national register [ 7 ]. It is not the intention of this paper to advocate for the development of a register, but to consider the challenges we faced in accessing a reliable sampling frame for an esoteric area of research.…”

A priori sample size calculations are used to determine the adequate sample size to estimate the prevalence of the target population with good precision. However, published audits rarely report a priori calculations for their sample size. This article discusses a process in health services delivery mapping to generate a comprehensive sampling frame, which was used to calculate an a priori sample size for a targeted clinical record audit. We describe how we approached methodological and definitional issues in the following steps: (1) target population definition, (2) sampling frame construction, and (3) a priori sample size calculation. We recommend this process for clinicians, researchers, or policy makers when detailed information on a reference population is unavailable.Electronic supplementary materialThe online version of this article (doi:10.1186/s13104-015-1247-0) contains supplementary material, which is available to authorized users.

“…Participation in school requires that students successfully navigate the school's physical, social and sensory context and meet the demands placed upon them by teachers and the school curriculum (Chapparo and Lowe, 2011). There is little evidence to guide the practice of professionals (including therapists and teachers) who may provide sensory supports to students with ASD in a school setting (Weeks et al, 2014). A school-based pilot study by used single system design research to evaluate the outcome of a sensory activity schedule (SAS), an intervention involving targeted opportunities to meet a student's sensory needs, in a school setting for students with ASD.…”

Purpose Sensory processing difficulties can negatively affect children with autism at school. There is limited evidence to guide practice in this area. The purpose of this study is to evaluate the efficacy of a sensory activity schedule (SAS) used in a school setting on task mastery and occupational performance in the classroom. Design/methodology/approach A randomised control trial (RCT) was conducted with 30 children to evaluate the efficacy of a school-based SAS. Children in the intervention group received SAS intervention and usual teaching. Children in the control group received only usual teaching. Outcome measures were the perceive, recall, plan and perform stage one procedural task analysis and goal attainment scaling. Findings Children in the intervention group demonstrated statistically significant improvements in school performance when compared with the control group in both outcome measures. Research limitations/implications This was a pilot study with small sample size, so results should be interpreted with caution. Further research is needed to replicate these findings. Practical implications A classroom-based SAS may have a positive effect on classroom performance for children with autism. This has implications for professionals who support children with autism and sensory processing difficulties in a school setting. Originality/value To the best of the authors’ knowledge, this study was the first of its kind in evaluating SAS intervention in a school setting using RCT methodology.
