About this study

Dental and health anxiety are common and potentially distressing problems, for both patients and health care providers. Anxiety has been identified as a barrier to regular dental visits and as an important target for enhancement of oral health-related quality of life. possible groups, (1) high dental anxiety and (2) low dental anxiety. The study aimed to develop and evaluate a computerized cognitive-behavioral therapy dental anxiety intervention (C-CBT) that could be easily implemented in dental healthcare settings.

A cognitive-behavioral protocol based on psychoeducation, exposure to feared dental procedures, and cognitive restructuring was developed. A randomized controlled trial was conducted (N=151) to test its efficacy. Consenting adult dental patients who met inclusion (e.g., high dental anxiety) and exclusion criteria were randomized to one of two groups, (1) immediate treatment (IT) (n=74) or (2) a waitlist control (WL) (n=77).

Read the detailed description

Analyses of covariance (ANCOVAs) based on intention to treat analyses were used to compare the two groups on dental anxiety, fear, avoidance, and overall severity of dental phobia. Baseline scores on these outcomes were entered into the analyses as covariates.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Computerized Dental Anxiety TreatmentBehavioural

    The Computerized Dental Anxiety Treatment Program consists of treatment modules that are be delivered through a computer. The modules use Cognitive Behavioral Therapy (CBT) to assist the participant in preparing a personal plan for managing his/her dental anxiety. The program incorporates a range of CBT techniques, including cognitive restructuring, exposure, and motivational interviewing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Modified Dental Anxiety Scale

    The Modified Dental Anxiety Scale a five-item self-report measure that assesses fear of dental procedures, including drilling, scaling and polishing (i.e., cleaning), and local anesthetic injections. Sample items include, "If you went to your dentist for treatment tomorrow, how would you feel?" and "If you were about to have your tooth drilled, how would you feel?" Items are rated on a five-point Likert-type scale ranging from 1 (not anxious) to 5 (extremely anxious). Scale 0-25. We considered patients who scored > 19 on the MDAS at baseline or endorsed at least two MDAS items > 4 to have high dental anxiety.

    Measured: Change from one week before dentist appointment to 1 month after dentist appointment

Secondary outcomes (3)
  1. Change in Clinical Severity Rating for Specific Phobia Module of Anxiety Disorders Interview Schedule for DSM-IV

    The Anxiety Disorders Interview Schedule for DSM-IV is a semi-structured diagnostic interview for assessing DSM-IV criteria for current anxiety, depressive, somatoform, and substance use disorders. For the present investigation, only the specific phobia module of the ADIS-IV was administered to assess the presence and severity of a current diagnosis of dental phobia. Various aspects of dental phobia were assessed using the specific phobia module of the ADIS-IV. Interviewers assessed participants' anxiety and avoidance of dental procedures on scales that ranged from 0 (none) to 8 (very severe). They also rated patients' overall distress and impairment due to their dental phobia symptoms and assigned a clinician's severity rating (CSR) that also ranged from 0 (none) to 8 (very severe); a CSR > 4 indicated that the participant met criteria for diagnosis of dental phobia.

    Measured: Change from one week before dental appointment to one-month after dental appointment

  2. Change in Fear Rating for Specific Phobia Module of Anxiety Disorders Interview Schedule for DSM-IV

    The Anxiety Disorders Interview Schedule for DSM-IV is a semi-structured diagnostic interview for assessing DSM-IV criteria for current anxiety, depressive, somatoform, and substance use disorders. For the present investigation, only the specific phobia module of the ADIS-IV was administered to assess the presence and severity of a current diagnosis of dental phobia. Various aspects of dental phobia were assessed using the specific phobia module of the ADIS-IV. Interviewers assessed participants' anxiety and avoidance of dental procedures on scales that ranged from 0 (none) to 8 (very severe). They also rated patients' overall distress and impairment due to their dental phobia symptoms and assigned a clinician's severity rating (CSR) that also ranged from 0 (none) to 8 (very severe); a CSR > 4 indicated that the participant met criteria for diagnosis of dental phobia.

    Measured: Change from one week before appointment to one month after appointment

  3. Change in Avoidance Rating for Specific Phobia Module of Anxiety Disorders Interview Schedule for DSM-IV

    The Anxiety Disorders Interview Schedule for DSM-IV is a semi-structured diagnostic interview for assessing DSM-IV criteria for current anxiety, depressive, somatoform, and substance use disorders. For the present investigation, only the specific phobia module of the ADIS-IV was administered to assess the presence and severity of a current diagnosis of dental phobia.
