To develop, validate, and apply an instrument for assessing the children's perception regarding pediatric dentist's appearance, based upon the influence of age, gender, previous dental experience, and anxiety.
Images and a nine-item questionnaire were developed. The acceptability, convergent-construct validity, and reliability based on reproducibility and internal consistency were evaluated. The validated instrument was applied in a cross-sectional study, with children (n=120) aged 7-12 years asked to evaluate images of pediatric dentists wearing different dental attire (A:all-white (control); B:printed coat and cap, colorful face mask; C:printed coat, cap and face mask; and D:white coat and cap, printed face mask). Children's age, gender, and previous dental experiences were collected with the guardians. The Children's Fear Survey Schedule-Dental Subscale assessed children's anxiety. Descriptive and inferential statistics were carried out (p<0.05).
The instrument showed excellent acceptability, construct validity with moderate and strong correlations (>0.40), satisfactory reproducibility (ICC >0.70), and internal consistency (Cronbach's alpha coefficient >0.70). Considering only the attire, the children's perceptions were more positive with the use of attire C and D (p<0.05). Intergroup analysis of all the variables did not identify a statistically significant difference (p>0.05). In the intragroup analysis, compared to attire A: younger children have higher perception scores to attire D; girls, children with previous experience and without anxiety favored attire C and D; and children without previous experience showed no difference in comparison to A but did between B and C (p<0.05).
The C and D attires promoted a more positive perception of the appearance of a pediatric dentist when compared to A; however, age, gender, previous dental experience, and anxiety did not influence the perception scores.
基于年龄、性别、先前的牙科经历和焦虑感的影响，开发、验证并应用一种评估儿童对儿科牙医外貌感知的工具。
制作了图像和九项问卷。评估了可接受性、聚合结构有效性以及基于再现性和内部一致性的可靠性。在一项横断面研究中应用了经过验证的工具，要求 7-12 岁的儿童（n=120）对佩戴不同牙科着装的儿科牙医图像进行评价（A：全白（对照）；B：印花外套和帽子，彩色面罩；C：印花外套、帽子和面罩；D：白色外套和帽子，印花面罩）。通过监护人收集儿童的年龄、性别和先前的牙科经历。使用儿童恐惧调查量表-牙科分量表评估儿童的焦虑感。进行了描述性和推断性统计分析（p<0.05）。
该工具表现出极好的可接受性、结构有效性，具有中度和强相关性（>0.40）、令人满意的再现性（ICC>0.70）和内部一致性（Cronbach's alpha 系数>0.70）。仅考虑着装，儿童对使用着装 C 和 D 的感知更积极（p<0.05）。对所有变量的组间分析未发现统计学上的显著差异（p>0.05）。在组内分析中，与着装 A 相比：年幼的儿童对着装 D 的感知评分更高；女孩、有先前经历且无焦虑感的儿童更喜欢着装 C 和 D；而无先前经历的儿童与 A 相比没有差异，但 B 和 C 之间存在差异（p<0.05）。
与 A 相比，C 和 D 着装使儿科牙医的外貌更受儿童欢迎；然而，年龄、性别、先前的牙科经历和焦虑感并未影响感知评分。
