Psychometric properties of the faces version of the Malay-modified child dental anxiety scale

(1) Background: The present study aimed to examine the psychometric properties of the Persian adaptation of the Modified Dental Anxiety Scale (MDAS) in Iranian adolescents. (2) Methods: Adolescents with a mean age of 15.10 (n = 3197; 47.1% males) were recruited from Qazvin city of Iran using a stratified cluster random sampling technique. All children completed the five-item Persian MDAS and information related to background characteristics. Psychometric testing was conducted using classical test theory (CTT) and Rasch models. For CTT, an item-total correlation of >0.4 was considered satisfactory while for Rasch analysis, infit and outfit mean squares (Mnsq) ranging from 0.5–1.5 were considered satisfactory. Confirmatory Factor Analysis (CFA) was conducted to confirm the unidimensional structure of MDAS using various fit indices. Differential item functioning (DIF) was evaluated based on gender and time since last dental visit. Moreover, latent class analysis (LCA) was used to classify the participants into different levels of dental fear based on their pattern of responses. Both item level reliability using Cronbachs alpha (α) and test-reliability using intraclass correlation coefficients were evaluated. (3) Results: Item-total correlations ranged from 0.69–0.78, infit MnSq ranged from 0.80 to 1.11 and the range of outfit MnSq was 0.84–1.10. The data confirmed a one-factor structure of MDAS with satisfactory fit indices. DIF analysis indicated that the scale was interpreted similarly across the genders and time since dental visit groups. LCA analysis identified three levels, low, moderate and high levels of dental anxiety. The groups with moderate and high levels of dental anxiety had more females (44.6% and 36.7%) than the group with low level of dental anxiety (18.8%; p < 0.001). α of the total scale was 0.89 and item test-retest reliability ranged from 0.72–0.86. (4) Conclusions: The Persian MDAS was unidimensional with satisfactory psychometric properties evaluated using both CTT and Rasch analysis among Iranian adolescents. The scale was stable across the genders and individuals with different dental visiting patterns. The Persian MDAS also demonstrated excellent reliability.

ABSTRACT Aim This study focused on the Modified Dental Anxiety Scale to determine the prevalence of dental anxiety and assess the psychometric properties in Nigerian population. Materials and methods Included in the study were 619 participants (204 males and 415 females) chosen conveniently from among the dental patients, students of post basic nursing and staff nurses, all from University of Benin Teaching Hospital, Benin City, Nigeria. The mean age was 31.34 (11.77) years. Participants completed a questionnaire containing the Modified Dental Anxiety Scale. Results The prevalence of high dental anxiety was found to be 10.7% at the cut-off point ≥ 19. Cronbach's alpha for the present Nigerian sample was 0.80. Factor analysis revealed one factor with an eigenvalue greater than 2. This factor explained 55.9% of the variance of the items. In addition, the MDAS showed a significant difference between the genders, with the female (X̄ =13.86;SD= 4.64) reporting higher dental anxiety score than the male (X̄ =12.62;SD= 4.73). Conclusion MDAS demonstrated satisfactory and acceptable psychometric properties. Therefore, dental surgeons, clinical psychologists, psychiatrists and other therapists can use MDAS as an objective tool for detecting and possible management of high dental anxiety in Nigeria.

The Difference

Abstract Background Dental anxiety is associated with negative experiences of dental treatment and dental-visiting behavior. The Modified Dental Anxiety Scale (MDAS) is widely used for assessing dental anxiety. The study aims to establish the psychometric properties of a Chinese version of the MDAS based on the Taiwan sample (i.e., T-MDAS). Methods The T-MDAS and dental-visiting behavior and experience were assessed for 402 adult subjects recruited from community and clinical sites. The following psychometric properties were assessed: (a) internal consistency, (b) temporal stability, (c) criterion-related validity (i.e., the association with the score of Index of Dental Anxiety and Fear, IDAF-4C), (d) discrimination validity (i.e., the difference in scores between the subjects with and without a habit of a regular dental visit, and (e) the construct validity from a confirmatory factor analysis (CFA). Results. The T-MDAS showed good internal consistency (Cronbach’s α = 0.88) and temporal stability (ρ = 0.69, p < 0.001). The score was significantly correlated with the score of the IDAF-4C (ρ = 0.76, p < 0.001) and differed between subjects who regularly visited a dentist or not, supporting good criterion-related validity and discrimination validity. Results from CFA supports good construct validity. Furthermore, higher dental anxiety was related to the lack of a regular dental visit, feeling pain during treatment, and feeling insufficient skills and empathy of dentists. A higher proportion of high-dental anxiety subjects in female subjects (8.5%), compared to male subjects (5.0%), was noted. Conclusions The T-MDAS is a valid tool for assessing adult dental anxiety. The score is highly associated with dental-visiting behavior and experience of dental patients.

The study aims at identifying and highlighting dental anxiety in a group of young adults, analyzing patients� concerns about the main dental treatment procedures, and establishing statistical relationships between anxiety and gender, the background, level of education, socio-economic status and knowledge of habits of care and hygiene of oral cavity characteristic of the studied group. The study group consists of 150 female (50%) and male (50%) patients , aged between 20 and 40 years. The inclusion criteria in the batch were those related to the age range of 20 to 40 years.Two respondents (Corah�s Dental Anxiety Scale, Revised (DAS-R)) were given two questionnaires ( Corah�s Dental Anxiety Scale, DAS-R), and the second questionnaire contained 7 questions about the habits dental care). Most patients� concerns about the main procedures of dental treatment / other concerns are: dental extraction, material expenses, possibility of treatments and shame she felt oppressed health of the oral cavity. Regardless of the level of dental anxiety, the oral cavity hygiene habits are not properly performed by patients, with an increased tendency for them to be disregarded by patients with severe dental anxiety.
