To develop the Finnish version of the Orofacial Esthetic Scale (OES-Fi) and the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ-Fi) and estimate the psychometric properties of these instruments applied to adult Finns.
The English versions of the instruments were translated into Finnish and back-translated. Thereafter, OES-Fi and PIDAQ-Fi were established in a pilot study. The factorial validity was estimated using Confirmatory Factor Analysis (CFI, TLI, SRMR) in independent samples (Test and Validation samples). The measurement invariance of the factorial models was tested using multigroup analysis (ΔCFI). Convergent validity [Average Variance Extracted (AVE)] and reliability [Composite Reliability (CR) and α] were estimated.
A total of 3636 individuals [mean age = 32.0 (SD = 11.6) years, 75% women] participated in the study. After refinements, the factorial model of the instruments showed an adequate fit to the data (CFI ≥0.94, TLI ≥0.90, SRMR ≤0.07) and showed measurement invariance in two independent samples (|ΔCFI| <0.01). Convergent validity (AVE = 0.54-0.82) and reliability ( = 0.86-0.94) were adequate.
The data obtained using OES-Fi and PIDAQ-Fi were valid and reliable. Thus, these instruments could be useful for evaluating individual satisfaction with orofacial appearance and the psychosocial impact of dental aesthetics in a clinical or research setting.
开发芬兰版的口腔美学量表（OES-Fi）和口腔审美心理社会影响问卷（PIDAQ-Fi），并评估这些工具在成年芬兰人中的心理测量学特性。
将工具的英文版本翻译成芬兰语并回译。此后，在试点研究中建立了 OES-Fi 和 PIDAQ-Fi。使用验证性因素分析（CFI、TLI、SRMR）在独立样本（测试和验证样本）中评估结构效度。使用多组分析（ΔCFI）测试因子模型的测量不变性。评估收敛效度[平均方差提取（AVE）]和可靠性[综合可靠性（CR）和α]。
共有 3636 名个体[平均年龄 32.0（SD=11.6）岁，75%为女性]参加了这项研究。经过改进，这些工具的结构模型与数据具有较好的拟合度（CFI≥0.94，TLI≥0.90，SRMR≤0.07），并在两个独立样本中具有测量不变性（|ΔCFI|＜0.01）。收敛效度（AVE=0.54-0.82）和可靠性（=0.86-0.94）良好。
使用 OES-Fi 和 PIDAQ-Fi 获得的数据有效且可靠。因此，这些工具可用于在临床或研究环境中评估个体对口颌面部外观的满意度和口腔审美心理社会影响。
