This cross-sectional study was approved by the ethical committee of the Faculty of Dentistry/Faculty of Pharmacy, Mahidol University in accordance with the ethical standards laid down in the 1964 World Medical Association Declaration of Helsinki and its later amendments and was registered with Thai Clinical Trials Registry. Based on the results of Marshall et al. [Parents (father or mother) of autistic people, aged < 35 years, from Mahidol University dental hospital and members of the Autism online community, which consisted of Thai parents of autistic people, were invited to participate in this study. All participants were contacted individually via phone calls and briefed about the research objective and the procedures of the study by a single operator. Then, they were allowed to ask questions about this study if any. Subsequently, informed consent was obtained from all parents before enrolling them in the study. Parents who were blind, deaf, had language difficulties, or unable to read and understand Thai language were excluded.The online questionnaire survey was conducted via Surveymonkey.com (Survey Monkey Inc., California, USA) and was divided into two primary components. The first component was designed to collect data concerning the parents and their autistic children, including their advanced BGT experience. Parents were divided into two subgroups, viz., the “Experience group” and the “No experience group,” according to their child’s advanced BGT experience (PRBD, OS, or GA) based on the AAPD behavior guidance for pediatric dental patients published in 2020 [The validity of the questionnaire was evaluated using the index of item-object congruence (IOC) from three pediatric dentists. The IOC for each question had a score of 0.67–1.00. The reliability of the questionnaire was checked by 10 parents who were invited to complete the questionnaire and were retested after a month. The intraclass correlation coefficient values ranged from 0.8 to 1.0.Parents were required to complete both component 1 and component 2 before submitting the online questionnaire. After watching each random advanced BGT video clip, they had to rate the VAS to represent their level of acceptance within 15 s and had 3 min to comment on each BGT after watching each technique before moving to the next technique. Then, the parents continued performing the same steps until they completed all three advanced BGTs.
