To evaluate the Dental Hygienist Beliefs Survey (DHBS) and the test-retest reliability of DHBS in a group of general dental patients.
The DHBS, which is a questionnaire constructed to assess patients' specific attitudes towards dental hygienists (DHs), was distributed together with the Dental Anxiety Scale adapted to specifically assess fear of DH treatment (DHAS). It was hypothesized that DHBS would correlate with DHAS and gender. The questionnaires were consecutively distributed to 80 patients at their first visit and after a clinical examination performed by a DH student. Retest assessments of DHBS were conducted approximately two weeks later in conjunction with the next visit at the DH student and before treatment (scaling session). The final study sample included 77 adult general dental patients in treatment at an education clinic for DH students.
The results verified a statistically significant correlation between DHBS and DHAS. The DHBS sum of scores showed high internal consistency with Cronbach's a coefficient of 0.88 and 0.91 at the first and second assessments, respectively, and the test-retest reliability of the DHBS was acceptable with intraclass correlation coefficient of 0.76. No statistically significant association was found between DHBS and gender.
The results suggest that the DHBS is a reliable and stable scale to use to assess patients' specific attitudes towards DHs. Moreover, DH beliefs are associated with fear of DH treatment.
评估牙科保健员信念调查（DHBS）在一组普通牙科患者中的重测信度。
DHBS 是一个专门用来评估患者对牙科保健员（DH）特定态度的问卷，与专门评估对 DH 治疗恐惧的牙科焦虑量表（DHAS）一起发放。假设 DHBS 将与 DHAS 和性别相关。问卷连续分发给 80 名首次就诊的患者，并由 DH 学生进行临床检查后。大约两周后，在 DH 学生的下一次就诊和治疗前（洁牙阶段）进行 DHBS 的重测评估。最终研究样本包括在 DH 学生教育诊所接受治疗的 77 名成年普通牙科患者。
结果验证了 DHBS 与 DHAS 之间存在统计学显著相关性。DHBS 总分显示出较高的内部一致性，第一次和第二次评估的 Cronbach's a 系数分别为 0.88 和 0.91，DHBS 的重测信度可接受，组内相关系数为 0.76。DHBS 与性别之间无统计学显著关联。
结果表明，DHBS 是一种可靠且稳定的量表，可用于评估患者对 DH 的特定态度。此外，DH 信念与对 DH 治疗的恐惧有关。
