Quality-of-life before and after cognitive behavioral therapy (CBT) in patients with intra-oral injection phobia

Effect of a hospital-based oral health-education program on Iranian staff: evaluating a theory-driven intervention

BACKGROUND

Tooth decay and periodontitis are among the most prevalent dental diseases globally with adverse effects on an individual's general health. Recently the prevalence of dental caries has decreased significantly, but caries epidemiology remains a major problem in dental public health. This study investigated the impact of an oral health education intervention on Theory of Planned Behavior (TPB) variables, and whether changes in these variables persisted and were associated with changes in identified oral health behaviors at 2-month follow-up.

METHODS

This descriptive pre/post test study was conducted with 160 staff in the Baqiyatallah Hospital in Tehran. Six hospital wards were selected using a randomized multi-stratified sampling frame. The size for each cluster was calculated as 22 with each ward being allocated to either the intervention or the control arm of the study. Self-report questionnaires were used to evaluate socio-demographic factors, dental attendance as well as the constructs of the augmented TPB model (attitudes, subjective norms, perceived behavioral control intentions). The intervention was an educational program based on TPB constructs delivered via direct training to half the participants. The control group was provided with usual training only. The independent-samples T-test, Repeated-Measures one-way ANOVA, and matched T-test with the significance level set at p < 0.05 were applied.

RESULTS

Findings revealed significant variations between the two groups immediately after the educational intervention concerning the attitudes, subjective norms, perceived behavioral control, intentions to seek treatment, oral health behavior as well as decayed, missing, and filled teeth and bleeding on probing (p<0.001). Two months after the intervention, except for the brushing construct (p = 0.18), the differences between the two groups were all statistically significant (p<0.001).

CONCLUSION

Our findings affirm the positive effect an oral health education program has on enhancing the attitudes, subjective norms, perceived behavioral control, intentions and behavior of staff in this hospital. The results of our study confirm that developing and applying an educational intervention in accordance with the theory of planned behavior can lead to significant changes in the knowledge, attitudes, and behavior of hospital staff regarding preventing tooth decay.

Outcome of Chair-Side Dental Fear Treatment: Long-Term Follow-Up in Public Health Setting

Aim

Purpose of this practice and data-based study was to evaluate the outcome of dental fear treatment of patients referred to the Clinic for Fearful Dental Patients (CFDP) in the primary oral health care, City of Oulu, Finland, during period 2000–2005.

Methods

A psychological approach including behavioral interventions and cognitive behavioral therapy (BT/CBT) was used for all participants combined with conscious sedation or dental general anesthesia (DGA), if needed. The outcome was considered successful if later dental visits were carried out without any notifications in the patient records of behavioral problems or sedation. Data collection was made in 2006; the average length of the observation period from the last visit in the CFPD to data collection was 2 y 3 m (SD 1 y 5 m). All information was available for 163 patients (mean age 8.9 y at referral). Study population was dominated by males (58.0%). Cause for referrals was mostly dental fear (81.0%) or lack of cooperation.

Results

The success rate was 69.6% among females and 68.1% among males. Success seemed to be (p=0.053) higher for those treated in ≤12 years compared with the older ones. The participants, without need for dental general anesthesia (DGA) in the CFDP, had significantly a higher success rate (81.4%) compared with those who did (54.8%, p < 0.001). Use of conscious oral sedation (p=0.300) or N₂O (p=0.585) was not associated with the future success.

Conclusions

A chair-side approach seems successful in a primary health care setting for treating dental fear, especially in early childhood. Use of sedation seems not to improve the success rate.

Can a brief psychological intervention improve oral health behaviour? A randomised controlled trial

Background

Dental caries is a major public health issue affecting a large proportion of the general population. The disease is associated with behavioural factors and is thus preventable to a high degree. Individuals may need assistance to be able to change their oral health behaviour. There is a lack of such interventions for adults affected by severe caries. The aim of the study was to evaluate the effect of Acceptance and Commitment Therapy (ACT), a form of cognitive behavioural therapy, on oral health behaviour in young adults with poor oral health.

Methods

The study included a two group parallel randomised controlled trial at general dental clinics, with young adults, 18–25 years of age, ≥ two manifest proximal dental caries lesions (n = 135); 67 were treated with ACT and 68 with standard disease information only, respectively. Primary outcomes: oral health behaviours (tooth-brushing, flossing, use of toothpicks, and additional fluoride use). The CONSORT principles for RCTs were used, including intention-to-treat and per protocol analyses. The Chi-square, Mann-Whitney, and Wilcoxon Signed Rank tests were applied, including effect sizes.

Results

The study groups did not differ with regard to oral health behaviour variables at baseline. The intervention group improved all their oral health behaviours significantly over time (effect sizes, 0.26–0.32), while the control group showed improved behaviours on two measures (flossing and additional use of fluoride, effect sizes, 0.22–0.23).

Conclusions

By testing a psychological intervention on young adults (18–25 years of age) with a high prevalence of caries, we found an immediate positive effect with improved oral health behaviours.

Effect of cognitive-behavioral therapy for anxiety disorders on quality of life: a meta-analysis

OBJECTIVE

Although cognitive-behavioral therapy (CBT) is effective for treating anxiety disorders, little is known about its effect on quality of life. To conduct a meta-analysis of CBT for anxiety disorders on quality of life, we searched for relevant studies in PubMed, PsycINFO, and the Cochrane Library and conducted manual searches.

METHOD

The search identified 44 studies that included 59 CBT trials, totaling 3,326 participants receiving CBT for anxiety disorders. We estimated the controlled and within-group random effects of the treatment changes on quality of life.

RESULTS

The pre-post within-group and controlled effect sizes were moderately strong (Hedges's g = 0.54 and Hedges's g = 0.56, respectively). Improvements were greater for physical and psychological domains of quality of life than for environmental and social domains. The overall effect sizes decreased with publication year and increased with treatment duration. Face-to-face treatments delivered individually and in groups produced significantly higher effect sizes than Internet-delivered treatments.

CONCLUSION

CBT for anxiety disorders is moderately effective for improving quality of life, especially in physical and psychological domains. Internet-delivered treatments are less effective than face-to-face treatments in improving quality of life.
