Validating a measure of children's monitoring-blunting coping styles in dental situations

Cross-cultural adaptation, validity and reliability of the Chinese Version of Miller Behavioral Style Scale

BACKGROUND

Health education basing on patients' information-seeking styles can improve the effectiveness of health education and patients' health outcomes. The Miller Behavioral Style Scale (MBSS) is widely used to identify individual's information-seeking styles, but the Chinese version is lacking. The study aim was to translate and culturally adapt the MBSS into Chinese version and test the content validity, construct validity and internal consistency reliability of the Chinese version of MBSS (C-MBSS).

METHODS

The forward-back-translation procedure was adopted in the translation of the MBSS. Content validity was assessed in a panel of experts. In a sample of 1343 individuals including patients, patients' caregivers, university students, and medical staff, reliability and construct validity were assessed using Cronbach's alpha coefficient and factor analysis. The measurement invariance across samples was tested using multigroup confirmatory factor analysis (MGCFA). Floor and ceiling effects were checked.

RESULTS

The C-MBSS achieved conceptual and semantic equivalence with the original scale. The item-level content validity index (I-CVI) of each item ranged from 0.78 to 1, and the averaging scale-level content validity index (S-CVI/ Ave) was 0.95. The exploratory factor analysis resulted in 2-factor assumption for each hypothetical threat-evoking scenario. Confirmatory factor analysis demonstrated a good fit between theoretical model and data, which provided confirmatory evidence for the second-order factor structure of 2-factor solution (Monitoring and Blunting). The Cronbach's alpha coefficients for the Monitoring and Blunting sub-scales of the C-MBSS were 0.75 and 0.62 respectively. MGCFA results supported the measurement invariance for the Monitoring sub-scale of the C-MBSS across samples. No floor or ceiling effects occurred.

CONCLUSIONS

This study indicates that the C-MBSS has good content and construct validity. The Monitoring sub-scale of the C-MBSS had acceptable internal consistency reliability while the Blunting sub-scale had unsatisfactory one, which suggest that the Monitoring sub-scale of the C-MBSS can be used to identify individuals' information-seeking styles in Chinese contexts across different populations.

What the child "SAID" to the dentist: A UK randomized controlled trial

BACKGROUND

The electronic Survey of Anxiety and Information for Dentists (eSAID) allows children to tell dentists about their feelings and coping preferences. It is a computer "quiz" with 26 questions and free-text responses that produces a report for the children that they can then hand to their dentist. This is the first study to report the use of eSAID in a hospital paediatric dental clinic.

METHODS

This was a randomized controlled trial to evaluate whether children thought that eSAID benefitted them, made them less anxious, and improved cooperation and their treatment satisfaction. Fifty-one children aged 8-13 years were randomized to complete either eSAID or a control version in the waiting room before their scheduled dental appointment. The study group had a 26-item questionnaire; the control had only two items. Both groups scored their anxiety on a 7-point anxiety scale at the start and again at the end of the quiz. All subjects handed the resultant eSAID report as a printout to their dentist. Dental treatment proceeded as planned. After treatment, each child reported how they thought the eSAID quiz had benefitted them by scoring on a 10 cm Visual Analogue Scale and their satisfaction on the Modified Treatment Evaluation Inventory. The operating dentists scored the children's cooperation using a 10 cm Visual Analogue Scale.

RESULTS

Overall, the baseline anxiety levels were low (study: mean 1.2; control: mean 1.5). The study group's post-survey anxiety reduced by 0.4, whereas controls' increased by 0.2; this difference is statistically significant (p = .04). However, it made no difference to the children's self-reported benefit (p = .30), satisfaction (p > .05), or cooperation (p = .34).

CONCLUSIONS

eSAID reduced pre-treatment anxiety but made no difference to children's perceived benefit, satisfaction, or cooperation. Future study should include known anxious children.

Validation and randomized control trial of the e-SAID, a computerized paediatric dental patient request form, to intervene in dental anxiety

BACKGROUND

A rationale for, and pilot of a children's patient request form developed specifically for dental visits, has been previously reported. The SAID (survey of anxiety and information for dentists) is a questionnaire with three embedded subscales: dental anxiety, coping style and dental neglect. It includes children's requests for emotional support, information and treatment. The main, but not sole, response format is a facial image scale. A randomized control trial of a computer version is now reported. The aims were to validate items in the e-SAID, and to assess it as an intervention in dental anxiety.

METHOD

A total of 168 children aged 10-13, attending for routine dental checks in a community dental clinic, were randomly assigned to intervention (83) or control (85) groups. The intervention group completed the e-SAID, in which the first and last questions measured anxiety; and printed a summary of their responses for the dentist. Control group children completed the same anxiety questions, but with a time-lapse.

RESULTS

Means and SD were summarized for the 11 items showing a generally positive skew on the seven point scale. After removing the two-item dental neglect subscale, the anxiety and coping subscales were shown to be relatively independent (r = 0.14) and factorially pure. The intervention group mean anxiety score decreased following completion of the e-SAID, while the control group mean anxiety score increased with a small significant interaction effect; however, much of the change occurred in the positive-affect end of the scale.

CONCLUSIONS

Two problems are discussed: defining anxiety as a bipolar score; and some children being so keen to be assigned to the intervention group that they circumvented the computer allocation process. Children wanted to actively engage in discussion of their dental treatment. The e-SAID was an effective tool for that, regardless of initial low anxiety levels.

Can virtual nature improve patient experiences and memories of dental treatment? A study protocol for a randomized controlled trial

Background

Dental anxiety and anxiety-related avoidance of dental care create significant problems for patients and the dental profession. Distraction interventions are used in daily medical practice to help patients cope with unpleasant procedures. There is evidence that exposure to natural scenery is beneficial for patients and that the use of virtual reality (VR) distraction is more effective than other distraction interventions, such as watching television. The main aim of this randomized controlled trial is to determine whether the use of VR during dental treatment can improve the overall dental experience and recollections of treatment for patients, breaking the negative cycle of memories of anxiety leading to further anxiety, and avoidance of future dental appointments. Additionally, the aim is to test whether VR benefits dental patients with all levels of dental anxiety or whether it could be especially beneficial for patients suffering from higher levels of dental anxiety. The third aim is to test whether the content of the VR distraction can make a difference for its effectiveness by comparing two types of virtual environments, a natural environment and an urban environment.

Methods/design

The effectiveness of VR distraction will be examined in patients 18 years or older who are scheduled to undergo dental treatment for fillings and/or extractions, with a maximum length of 30 minutes. Patients will be randomly allocated into one of three groups. The first group will be exposed to a VR of a natural environment. The second group will be exposed to a VR of an urban environment. A third group consists of patients who receive standard care (control group). Primary outcomes relate to patients’ memories of the dental treatment one week after treatment: (a) remembered pain, (b) intrusive thoughts and (c) vividness of memories. Other measures of interest are the dental experience, the treatment experience and the VR experience.

The rationale and pilot study of a new paediatric dental patient request form to improve communication and outcomes of dental appointments

BACKGROUND

Children's unhappy visits to the dentist can negatively impact lifelong oral health. A possible intervention is to enhance empathy in the child patient-dental practitioner relationship through communication. The present paper presents a new instrument, the Survey of Anxiety and Information for Dentists (SAID), which targets children's dental anxiety, coping preferences and dental neglect, and offers children a change to request information and engage in treatment planning.

METHOD

Five children's focus groups pilot tested the content, wording and response format of a prototype patient request form, the SAID. Participants were 34 10- to 13-year-old children who individually completed the form then discussed it item by item in their small groups.

RESULTS

Children had no difficulty completing most items. They identified ambiguities, and items that were meaningless to them, and proposed a new item asking the dentist about their job. Children were polarized over the response format, but they were emphatic about passing the form directly to the dentist, and not to a receptionist or assistant, stressing the importance of having a conversation with their dentist.

CONCLUSIONS

Before the pilot, dentists had expressed concerns about the potential for words in the SAID-provoking negative feelings. Children, however, wanted and needed facts, so requested that dentists use plain language, not euphemisms, to describe problems and treatment options. We report their selected practical suggestions. SAID-informed negotiated care may promote more patient cooperation and satisfaction at appointments, and more attention to oral hygiene between appointments.
