Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The following stages of the study will generally take place during two to three weekly
visits to the child's home, dependent on family availability. All participants will progress through the following phases. Procedures will be implemented by a Masters level behavior therapist, under the supervision of a Registered Psychologist and Board Certified Behavior Analyst (BCBA)

Assessment
- Interview with parents to gather more information regarding child's feeding habits,
routines, mealtime problem behaviours and parent's feeding goals. An overall list of
12 target foods will be developed.
- Caregiver will complete the Behavioural Pediatrics Feeding Assessment Scale
(BPFAS)
- Meal observation - the caregiver will be instructed to present foods to their child,
one at a time, from an initial group of 4 target foods. They will otherwise be
instructed to act as they usually would. This meal will continue for up to 15 min, or
may end early if the caregiver requests to do so.
-
Intervention
Intervention sessions will generally be conducted by the behavior therapist 2-3 times per week, depending on
family availability. The length of each meal session will be limited to 20 minutes.
Each meal session will generally involve a group of four foods, and all foods will
initially be presented in pea-size bites. Caregivers will be requested to sit at the
table and participate in each session.
If a child leaves the table during any meal session, the experimenter will remove
access to toys or other activities and state "it's our meal time now". If the child does
not return to the table within 5-minutes, the session will be terminated for that day.
The interventions will be introduced in the following order. If after at least three
meals, the child is not consuming at least 80% of foods, we will proceed to the next
listed intervention.
Intervention A. Repeated Exposure
During repeated exposure, four foods will be prepared and ready. The experimenter
will use flashcards to randomly choose a different food to present to the child, one at
a time. The experimenter will place the food on a small plate in front of the child,
with the instruction "Try ___". The food may be presented on a spoon to the child
where required (e.g., yoghurt). If the child approaches (e.g., tastes, licks) or accepts
the food within 15-seconds, the experimenter and caregiver will provide praise
specific to the child, for instance "well done [child's name], you are doing so great".
If the child has placed the food in their mouth, after 15-s the experimenter will
instruct the child to 'show me' and check that the child has swallowed the bite of food
(praise provided). If the child has not swallowed the bite of food, they will be
instructed again to do so.
If the child does not approach or accept the food within 15-s of acceptance the
experimenter will remove the food with no comment, and then present the next food
with instruction.
Procedural integrity (i.e., treatment fidelity) will be monitored by measuring experimenter behavior against a checklist that outlines the components of treatment.

After an initial session, behavioural skills training (BST) will be used to teach parents
to conduct repeated exposure sessions on days where the experimenter is not
present. Behavioural skills training will involve reading written instructions together,
the experimenter modelling the procedures, and the caregiver and experimenter (or
child) role-playing the procedures. Caregiver adherence will be monitored by reminders (e.g., text message or email), as well as the caregiver completing a brief data sheet for each meal session.

Intervention A+B: Repeated exposure + Modelling
Repeated exposure will continue as above, though modelling will be involved as an
additional component.

Throughout the session, the experimenter and caregiver will now also have plate/s
containing the target foods and will eat small pieces. At regular time they will
express positive responses such as "oh this [name of food item] is delicious".
As described above, parents will then be instructed to add modelling to sessions
where the experimenter is not present.

Intervention A+B+C: Repeated exposure+ Modelling + Reinforcement
To identify reinforcement that is most relevant to the child, we will conduct an
assessment known as a Functional Analysis. A functional analysis looks to identify
potential reasons for food refusal, which are commonly a) caregiver attention, b)
escape from eating (the meal ending or food removed), and/or c) access to preferred
foods or activities (e.g., providing chips instead, turning TV on).
Information used from the initial interview and prior meal sessions will be used to
develop two conditions:

• CONTROL condition: the reported consequences of food refusal are absent. If the
caregiver highlighted that attention and preferred foods are often provided upon
food refusal, this condition would involve providing attention and preferred foods
continuously.

• TEST condition: the reported consequences of food refusal are present in this
condition. In comparison to the control condition example, the test condition would
involve the caregiver providing attention and a preferred food upon every instance
of food refusal.

The assessment would involve 5-minute conditions, rotating between the control and
test condition. If we see higher levels of problem behaviour in one condition over
another, this indicates potential events that are motivating for the child (such as
attention). If we do not see changes in the level of behaviour across conditions, we
will conduct further interview with the caregiver and modify conditions.
Once we have identified the relevant reinforcer, further intervention sessions will
involve providing this reinforcer upon acceptance of bites of food. The session will
continue to involve repeated exposure and modelling as described previously.
However, the child will be instructed at the start of sessions that "taking a bite" will
result in "________" (supported by a visual where required). During the session, if
the child accepts the bite within 15-s, praise will be provided as previously described,
as well as access to the reinforcer (e.g., attention and a bite of preferred food). If the
child does not accept the bite within 15-s, it will be removed with no comment and
the next food will be presented.
If this intervention level is effective for the child, we will continue with caregiver
training as described for the previous phases. As reinforcement is more detailed,
training is likely to require more time than previous interventions.
If this intervention level is not effective for the child, we will attempt further sessions
with a higher level of reinforcement (e.g., larger bites of preferred food), or reduce
the eating expectations (e.g., touching the food to the mouth results in
reinforcement). If modified procedures do not result in improvements within three
further meals, we will end the study for the child. If the caregiver consents, we will
assist with referral to an appropriate provider (e.g, speech language therapy, child
development team).
End of the study

The study will end for the child when they consume at least 80% of bites, during at
least three meals which involve 12 target foods, or by November 15th 2019,
whichever occurs earlier
At the end of the study, The BPFAS will be provided to the caregiver to be
completed again
The caregiver will be asked to complete a brief satisfaction survey
Follow-up
The experimenter will visit the family 1 and 3 month(s) after intervention. The
caregiver will be asked to conduct a meal during each visit, using foods that were
previously used during the intervention, as well as new foods.
