Healthy Eating Learning Program (HELP) Study for Children with Autism Spectrum Disorder
Scientific title
In children with Autism Spectrum Disorder and feeding difficulties, is traditional operant conditioning intervention more effective than novel systematic desensitisation intervention at improving dietary variety and nutrition, and decreasing maladaptive mealtime behaviours and parental stress?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm One: One-on-one behaviour modification therapy Run in an individual session for 1 hour per week over ten weeks (weekly schedule) or 10 times over one week (intensive schedule) Involves providing a verbal prompt to encourage consumption of spoonfuls of new food/s, with positive reinforcement (verbal and/or with toys etc) upon consumption of these foods. Parents initially observe from behind a one-way mirror and assist in collecting information about the behaviours they are observing in their child. As sessions continue, parents are transitioned into the room, and are trained to offer new foods and provide positive reinforcement by the end of the therapy block. Parents also receive standardised information about nutrition, behaviour management and feeding development. Arm Two: Systematic desensitisation therapy Run in an individual session for 1 hour per week over ten weeks (weekly schedule) or 10 times in one week (intensive schedule) Involves the child being exposed to gradually more challenging modelling and play with food (based on a sensory hierarchy of look>touch>smell>taste). Parents initially observe the sessions from behind a one-way mirror with a second therapist and assist in observing transitions and reactions in their children. As the block continues, parents are rotated in and out of the room to assist in modelling play using the sensory hierarchy. Parents also receive standardised information about nutrition, behaviour management and feeding development.

Comparator / control treatment
Natural control will be waiting for therapy. These children will either be offered input via an intensive schedule (as described above) or during a subsequent 10-week block. As recruitment for this study will occur in an ongoing fashion, there will be multiple opportunities to access therapy if it is not immediately available.

Outcomes
Primary outcome [1] 266835 0
Adequacy of diet and overall increase in dietary variety

Assessed via 3-day weighed food diary, modified Children's Dietary Questionnaire (Magarey et al. 1999)(food frequency questionnaire) and New Food Lists, where parents indicate in an ongoing fashion how many times their child is offered new foods and the number of acceptances or rejections

Secondary outcome [1] 276482 0
Improvement in mealtime behaviours (% desirable vs undesirable behaviours; mealtime duration)

Measured via Behaviour Pediatrics Feeding Assessment (Adapted from Crist et al. 2001), and self-developed HELP study: Eating Skills and Behaviours Questionnaire. Questionnaires involve parent-rated likert scales (parents rate level of concern).

Immediately post-intervention
3 months post-intervention
Secondary outcome [2] 276532 0
Improvement in mealtime interactions between parent and child

Measured via Dyadic Parent-Child Interaction Coding System (Revised) (Eyberg, 1994). A video-tape is taken of the parent interacting with their child in a non-food related activity, a parent offering their child a preferred food, and the parent offering their child a non-preferred food. All videos will be rated externally by the team psychologist who will not be working directly with the children involved.
Timepoint [2] 276532 0
3 months post-intervention
Secondary outcome [3] 276533 0
Improvement in parental stress (overall and mealtime specific)

Measured via self-developed HELP study: Parent percieved stress questionnaire and the Parenting Stress Index - Short Form.

Secondary outcome [4] 276534 0
Increased interest in trying unfamiliar foods

Measured with Children's Picky Eating Questionnaire (Adapted from Carruth and Skinner, 2000) and New Foods Lists, where parents indicate in an ongoing fashion how many times their child is offered new foods and the number of acceptances or rejections.

Eligibility
Key inclusion criteria
Children with a diagnosis of Autism Spectrum Disorder, or a pending diagnosis of Autism Spectrum Disorder

Limited dietary variety across core food groups: diet currently includes less than 10 foods which are predominantly carbohydrates, 10 foods which are predominantly proteins, and 10 fruits/vegetables; limited range of textures consumed; don’t eat an age-appropriate range of textures; limit diet to only 1 or 2 textures of foods; consume predominantly ‘easy-to-eat’ junk foods

Mealtimes are taking longer than 30 minutes

There are problematic behaviours at mealtimes, which are contributing to parental stress
Minimum age
1 Years
Maximum age
11 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Children who are medically unstable: this describes acutely unwell children who may experience a deterioration in health.

Children with documented aspiration on any solid food textures (children on modified liquids will be accepted)

Children with severe malnutrition, whose primary goal of nutrition could only be achieved by supplementary tube feeding

Children with gut malabsorption disorders, which are not well controlled or understood

Children with an allergy or current intolerance to more than 2 types of foods

Children whose primary health carer has a known/declared mental health condition

Children whose family’s primary language is that other than English or children identified as being of Aboriginal or Torres Strait Islander background

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomly generated numbers have been placed in sealed envelopes by a colleague who is not involved with the study. After children have received their initial assessment and are deemed eligible to receive intervention, the next envelope in the sequence will be opened.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated random number sequence will be used to allocate the numbers to sealed envelopes
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Inter-rater reliability for assessments where 10% of video-taped assessments requiring objective scoring will be reviewed by a blind clinician.

Coders for dietary variety measures and parent-child interaction measures will be blinded.
