A final set of 86 parent items, 65 physician items and 52 general public items were developed to represent the content domains.
As a result, for the purpose of this study, and from the review of literature, a list of parent involvement items for the questionnaire was prepared.
The loading of parent-rated item 10 ("fidgety") onto the emotional factor was also higher than that onto the predicted factor.
Content analysis of those data was carried out and results used to develop measures of parents' attitudes (6 items), subjective norms (7 items), perceived behavioural control (5 items) and behavioural intentions (3 items).
Future investigations of the similarities and differences in parent and teacher ratings could conduct latent class analysis on individual items of parent and teacher ratings, to identify whether parents and teachers are observing clusters of behavioural symptoms that fall into comparable groups.
The "Five to fifteen" (FTF) questionnaire [ 17] was developed in Scandinavia and consists of 181 parent assessed items covering the 8 developmental/neuropsychiatric domains "Motor control", "Executive function", "Perception", "Memory", "Language and speech", "Learning", "Social competence", and "Emotional/behavioral problems".
Second, we did not measure health literacy in this phase because we drew upon the responses of a wide range of parents in developing items for the cognitive interview and the subsequent field test.
Descriptive analysis was used for the information need of parents and for items about the actual information seeking behaviour, and parents' self-reported influence from the used information sources on their vaccination decision and their opinion of the NIP.
3) Habitual PA of parent was assessed using four items from the Behavioral Risk Factor Surveillance System, assessing frequency and duration (in 10-minute bouts or longer) of moderate and vigorous PA [ 45]. 4) Frequency of eating while watching TV was assessed with three items (mother, father, child, α =.681) from the Family Eating and Activity Habits Questionnaire [ 48].
4) SSB consumption of parent was assessed with one item: "Over the past week, how often did you drink regular soda or sugar-sweetened drinks?" Responses were given on an eight-point scale ranging from "Never" to "Every Day".
