Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The primary intervention drew on sensory integration theory (Bundy, Lane, & Murray, 2002). Five components built on an approach adapted from Anzalone and Williamson (2000) were considered as follows with a hypothetical example : 1) Observing and reframing sensory processing challenges in context (e.g., the child has an extreme reaction to the vacuum cleaner due to auditory over-responsiveness). The mother and the therapist, together, observed and discussed the behavior and developed management strategies. 2) Modifying the environment to reduce contributing sensory input (e.g., close doors to place a barrier between the child and the vacuum cleaner). 3) Modifying the activity to minimize unpleasant sensations (e.g., vacuum when the child is not home). 4) Managing the activity (e.g., use visuals to prepare for vacuuming; use calming sensory activities). 5) Promoting agency in the child in response to sensory challenges (e.g., teach the child to turn on a favorite TV show during vacuuming)..Four sessions occurred in the home for an hour once a week at a convenient time nominated by the family. The mother was the focus of the intervention, discussing intervention strategies and how they could be applied in the context of family routines. Sessions occurred over a four week period, however final scheduling was responsive to family needs.
A second intervention was provided to all participants based on the “Being Responsive” (Braithwaite, Keen, & Rodger, 2004) program. The program outlines four roles and six strategies to promote responsiveness and encourage interaction that are common in autism early intervention programmes (Roberts and Prior, 2006) . In this study, the program was modified, identifying and applying specific roles and strategies to manage the target behaviour of concern. The four intervention sessions occurred in the home, with the mother the focus of intervention in coaching/consultation model. The focus of the sessions were to identify how to apply strategies to increase responsiveness in the context of family routines. The mother applied the strategies identified with the child in the main, with some modelling or demonstration by the therapist as needed.
A fidelity checklist was completed by an independent rater, unfamiliar with the study. The rater completed the checklist after listening to a randomly selected audio recording of one session for each participant.
Two weeks break occurred between the two interventions which were randomly allocated to order of intervention for each participant.

Outcomes
Primary outcome [1] 296796 0
An individualized VAS was developed for each participant to rate behaviors that interfered with family routines that could be linked with sensory processing challenges. The VAS was programmed into an electronic handheld device (Palm Z22) using The Experience Sampling Program (ESP, Barrett & Barrett, 2005). Mothers received training with the Palm and were encouraged to find a suitable time to rate their perceptions of the child’s behavior each day. The VAS was anchored at both ends by statements relevant to the target behavior; specific criteria describing the target behavior were displayed each time the VAS was opened. The language and phrasing of these descriptors was developed collaboratively with the mothers to ensure focus on the same behavior over time. Mothers moved a slider along the VAS to reflect their perceptions of the behavior over the whole day generating a score out of 100.
Timepoint [1] 296796 0
The primary outcome was measured repeatedly over the baseline and intervention phases of the study, consistent with single case experimental design methodology. Mothers were asked to rate behaviour and their stress on a daily basis during the active phases of the study.

Eligibility
Key inclusion criteria
staff provided study information to parents of children newly diagnosed with ASD. Families were assessed on entry to the study and included if their child was between 3 and 5 years of age and had: (1) atypical sensory processing on the Infant Toddler Sensory Profile (ITSP, Dunn, 2002); (2) a behavior, nominated by the family that interfered with daily routines that was logically linked with sensory challenges (judged by the therapist); (3) autistic disorder based on scores on the Autism Diagnostic Observation Schedule(Lord, Rutter, & Le Couteur, 1995) administered by a psychologist trained to research reliability level; and (4) global developmental delay confirmed by clinic reports provided by parents.
Minimum age
3 Years
Maximum age
5 Years
Sex
Both males and females

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation to order of intervention was concealed from the families and the therapists. On confirmation of meeting the entry criteria, an independent researcher allocated to order of intervention using a random number generator.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random number generator was used for sequence generation

Efficacy
Statistical methods / analysis
Visual analysis of graphed repeated measures data from visual analogue scale outcome measure. Single case experimental design standards recommend 3 replications of a functional relationship between the introduction of intervention and behaviour change. Based on this requirement a minimum of 3 participants were required.
