Ethnographic perspectives of mothers and professionals on including children with disabilities in oral health in the Kingdom of Saudi Arabia.

BACKGROUND: Children with disabilities generally face poorer oral health outcomes compared with their non-disabled peers due to a range of factors including inadequate oral hygiene, infrequent dental visits and systemic barriers in accessing care. AIM: This ethnographic study explored the perspectives of caregivers and professionals to identify the ways that children with disabilities are included in oral health. DESIGN: A purposive sample of 10 caregivers, all mothers with disabled children aged 9-15 years, five healthcare providers and five educators in Saudi Arabia, participated. Data collection used participant observation and semi-structured in-depth interviews. Data were analysed using reflexive thematic analysis. RESULTS: The findings suggest that mothers lacked a supportive environment to develop their skills and knowledge about oral health care, preventing them from including their children in oral health. Inaccessible services added to the exclusion of both mothers and children. Some dental professionals exhibited poor communication skills and discriminatory attitudes towards the children and problematising mothers. Educators tended to discuss disabled children in terms of inability, displaying a deficit approach to impairment. CONCLUSIONS: The evidence suggests the exclusion of mothers from oral health. This has an impact on how they enable their children. Recommendations include adopting a social model of disability in dental education and policies in Saudi Arabia to address inequalities. Provision of support, education and focusing on societal barriers moves towards inclusion rather than conceptualising disability as an individual problem.

Using a theoretically informed process evaluation alongside a trial to improve oral health for care home residents.

BACKGROUND: Poor oral health is common among older adults residing in care homes impacting their diet, quality of life, self-esteem, general health and well-being. The care home setting is complex and many factors may affect the successful implementation of oral care interventions. Exploring these factors and their embedded context is key to understanding how and why interventions may or may not be successfully implemented within their intended setting. OBJECTIVES: This methodology paper describes the approach to a theoretically informed process evaluation alongside a pragmatic randomised controlled trial, so as to understand contextual factors, how the intervention was implemented and important elements that may influence the pathways to impact. MATERIALS AND METHODS: SENIOR is a pragmatic randomised controlled trial designed to improve the oral health of care home residents in the United Kingdom. The trial uses a complex intervention to promote and provide oral care for residents, including education and training for staff. RESULTS: An embedded, theoretically informed process evaluation, drawing on the PAHRIS framework and utilising a qualitative approach, will help to understand the important contextual factors within the care home that influence both the trial processes and the implementation of the intervention. CONCLUSION: Utilising an implementation framework as the basis for a theoretically informed process evaluation provides an approach that specifically focuses on the contextual factors that may influence and shape the pathways to impact a given complex intervention a priori, while also providing an understanding of how and why an intervention may be effective. This contrasts with the more common post hoc approach that only focuses on implementation after the empirical results have emerged.

Setting the context for a complex dental intervention of role substitution in care homes: Initial process evaluation findings.

OBJECTIVES: SENIOR (uSing rolE-substitutioN In care homes to improve oRal health) is a randomised controlled trial designed to determine whether role substitution could improve oral health for this population. A parallel process evaluation was undertaken to understand context. This paper reports on the first phase of the process evaluation. BACKGROUND: The oral health and quality-of-life of older adults residing in care homes is poorer than those in the community. Oral health care provision is often unavailable and a concern and challenge for managers. The use of Dental Therapists and Dental Nurses rather than dentists could potentially meet these needs. MATERIALS AND METHODS: Semi-structured interviews were conducted with 21 key stakeholders who either worked or had experience of dependent care settings. Questions were theoretically informed by the: Promoting Action on Research Implementation in Health Services (PAHRIS) framework. The focus was on contextual factors that could influence adoption in practice and the pathway-to-impact. Interviews were fully transcribed and analysed thematically. RESULTS: Three themes (receptive context, culture, and leadership) and 11 codes were generated. Data show the complexity of the setting and contextual factors that may work as barriers and facilitators to intervention delivery. Managers are aware of the issues regarding oral health and seek to provide best care, but face many challenges including staff turnover, time pressures, competing needs, access to services, and financial constraints. Dental professionals recognise the need for improvement and view role substitution as a viable alternative to current practice. CONCLUSION: Although role substitution could potentially meet the needs of this population, an in-depth understanding of contextual factors appeared important in understanding intervention delivery and implementation.

Access to oral health care services for children with disabilities: a mixed methods systematic review.

BACKGROUND: Children with disabilities experience poorer oral health and frequently have complex needs. The accessibility of oral health care services for children with disabilities is crucial for promoting oral health and overall well-being. This study aimed to systematically review the literature to identify the barriers and facilitators to oral health care services for children with disabilities, and to propose priority research areas for the planning and provision of dental services to meet their needs. METHODS: This was a mixed methods systematic review. Multiple databases searched included MEDLINE, Scopus, PsycINFO, EMBASE, and CINAHL. The search strategy included Medical Subject Heading (MeSH) terms related to children, disabilities, and access to oral health. Eligibility criteria focused on studies about children with disabilities, discussing the accessibility of oral health care. RESULTS: Using Levesque's framework for access identified barriers such as professional unwillingness, fear of the dentist, cost of treatment, and inadequate dental facilities. Facilitators of access offered insight into strategies for improving access to oral health care for children with disabilities. CONCLUSION: There is a positive benefit to using Levesque's framework of access or other established frameworks to carry out research on oral healthcare access, or implementations of dental public health interventions in order to identify gaps, enhance awareness and promote better oral health practices. The evidence suggests that including people with disabilities in co-developing service provision improves accessibility, alongside using tailored approaches and interventions which promote understanding of the importance of dental care and increases awareness for professionals, caregivers and children with disabilities.

Paediatric dentists' role in child protection practice: Progress over time?

BACKGROUND: Child maltreatment (abuse and neglect) is a global public health problem. Healthcare professionals must contribute to safeguarding and promoting the welfare of children at risk. AIM: To determine whether paediatric dentists' rates of child protection training, experience and practice have changed and to identify factors currently associated with maltreatment recognition and referral. DESIGN: A pre-piloted anonymous questionnaire was mailed to the UK-based British Society of Paediatric Dentistry members in 2005 (n = 789) and 2016 (n = 575). Analysis was conducted for practising dentists. RESULTS: Response rates were 66.3% in 2005 and 62.4% in 2016. Increases were observed in respondents' postgraduate child protection training (87.2% vs. 99.7%), multi-agency training (27.9% vs. 49.2%), ever suspected (67.9% vs. 82.3%) and ever referred child maltreatment (30.7% vs. 61.0%). The proportion who had suspected maltreatment but never referred a child reduced from 37.2% to 21.3%. Having referred more than five times in the preceding five years rose from 0.4% to 14.6% of respondents, yet those seeing children with neglected dentitions daily or more frequently remained unchanged. CONCLUSION: This repeated cross-sectional survey demonstrates a substantial improvement in UK paediatric dentists' training and practice, but a gap remains between suspecting and referring maltreatment concerns such that some children remain at risk.

Are oral health conditions associated with schoolchildren's performance and school attendance in the Kingdom of Bahrain? A life-course perspective.

BACKGROUND: The link between oral diseases and school performance and school attendance remains unclear among Middle Eastern children. AIM: To investigate the relationship of oral conditions with schoolchildren's school performance and attendance using the life-course approach. DESIGN: A cross-sectional study was conducted with 466 schoolchildren aged 7-8 years from Kingdom of Bahrain (KoB) and their parents. Questionnaire data on children's current and at-birth environmental characteristics were completed by their parents. Children's oral health measures, including ICDAS (International Caries Detection and Assessment System), PUFA (pulp, ulcer, fistula, abscess), and DDE (developmental defects of enamel) indices, were the exposure variables. School performance and school attendance data obtained from the school register were the outcome variables. The data were analysed using multivariate ordinal logistic regression. RESULTS: The odds of excellent school performance were significantly lower for children with untreated dentinal caries (OR = 0.98; 95% CI: 0.96-0.99). Children with caries-treated teeth showed greater odds of excellent school performance (OR = 1.41; 95% CI: 1.15-1.74). Disease Control and PreventionNone of the dental conditions were significantly associated with children's school attendance. A permissive parental style was associated with poor school attendance (OR = 2.63; 95% CI: 1.08-6.42). CONCLUSION: Dental caries was associated with poor school performance but not with school attendance. Treated caries was associated with good school performance.

Oral health experiences and perceptions of children with disabilities in the Kingdom of Saudi Arabia.

BACKGROUND: The clinical focus on oral health means there is a scarcity of evidence from the perspectives of children with disabilities because of the continuing exclusion of their views from oral health research. This study takes a rights-based approach, aiming to give disabled children a voice by exploring their oral health perspectives and experiences. In order to do this, innovative and inclusive methods are needed. AIM: The aim was to include the voices of children with disabilities by representing their perspectives and experiences of oral health. DESIGN: An ethnographic study employed a purposive sample of 10 children between the ages of 9 and 15 years with a range of intellectual disabilities and physical impairments attending special centres in Riyadh, Saudi Arabia. All children in the sample were female. Pluralistic methods enabled the inclusion of children in the research. Thematic analysis was used to analyse the data. RESULTS: The study describes different inclusive methods to enable children's voices on oral health. Main themes were children's knowledge, and their oral health practices and experiences of visiting dental clinics. Children also described the physical barriers they experienced and their positive and negative feelings about oral health. CONCLUSIONS: The study highlights that including children with disabilities in oral health research is possible, but that researchers need to be creative and be able to work in tandem with children. One goal for dental research is to include all children as active participants, working with them as collaborators. This would help transform services and reduce children's oral health inequalities.

Cross-cultural adaptation of the Arabic version of the DHEQ-15.

OBJECTIVES: Many patients who suffer from Dentine Hypersensitivity (DH) often go undiagnosed because they do not consider DH as serious problem that requires treatment. The use of patient-reported outcome measures can help in diagnosis and management of DH problems. The aim of the present study was to adapt cross-culturally the original English version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) for use in Arabic-speaking countries. METHODS: An Arabic version of DHEQ-15 was first developed by forward-backward translation and piloted among a group of dental patients. A cross-sectional study design was then used to test the psychometric properties of the Arabic DHEQ-15 in a wider convenience sample of Libyan dental patients diagnosed with DH. Confirmatory factor analysis was used to test the three-dimensional distribution of the subscales. The significance level of all statistical tests was set at p ≤ 0.05. RESULTS: The Arabic DHEQ-15 demonstrated good face and content validity. A total of 462 participants aged, on average, 39.2 ± 12.9 years took part in the psychometric testing of the Arabic DHEQ-15. The overall Cronbach's alpha of the questionnaire was 0.91, and overall Interclass correlation coefficient (ICC) for test-retest repeatability was 0.914. Participants with more severe DH had a significantly higher DHEQ-15 score than those with less severe DH (p < 0.001). Those who reported better global rating of their oral health had lower scores on the Arabic DHEQ-15 (p < 0.001). Confirmatory factor analysis confirmed three subscales of the Arabic DHEQ-15. CONCLUSIONS: The Arabic DHEQ-15 has been developed and further testing has demonstrated acceptable levels of psychometric properties in an Arabic population. The Arabic DHEQ-15 is a reliable measure of the quality-of-life impact of DH for use with Arabic-speaking populations.

Do psychological factors predict changes in oral health-related quality of life and clinical status after periodontal treatment?

AIMS: To determine psychological factors predicting changes in OHRQoL and clinical status after periodontal treatment. METHODS: Cohort of 140 patients with chronic periodontitis receiving non-surgical treatment consisting of scaling, root surface debridement and instruction in plaque control. Participants self-completed questionnaires enquiring about sense of coherence, locus of control, self-esteem and task-specific self-efficacy before treatment, and the Oral Health Impact Profile-14 before treatment, at oral hygiene review and end of study. Relationships among OHRQoL, clinical changes, individual factors (demographic and psychological) and environmental characteristics were analysed using latent growth curve modelling guided by the Wilson and Cleary model. RESULTS: OHRQoL and periodontal status improved after treatment. Being male and having a greater sense of coherence predicted better OHRQoL before treatment. Stronger internal dimension of locus of control predicted a greater rate of improvement in OHRQoL, whereas greater external dimensions predicted a slower rate of improvement. Greater task-specific self-efficacy predicted less gains in probing attachment and reductions in probing depth. CONCLUSIONS: Knowledge of psychological factors may be helpful in explaining individual differences in OHRQoL and clinical responses to periodontal treatment, and in identifying where health-promoting interventions may strengthen relevant factors to improve these outcomes.

Periodontal treatment, psychological factors and oral health-related quality of life.

AIMS: To determine changes in OHRQoL and clinical status after periodontal treatment and the factors predicting these changes. METHODS: Cohort of 140 patients with chronic periodontitis receiving non-surgical treatment. Participant self-completed questionnaires: Sense of Coherence, Locus of Control, Self-esteem and Task-specific Self-efficacy before treatment, and Oral Health Impact Profile at treatment, oral hygiene review and end of study. Relationships between OHRQoL, clinical data, individual and environmental characteristics were analysed with structural equation modelling guided by the Wilson and Cleary model. RESULTS: OHRQoL and the periodontal status improved after treatment. Greater sense of coherence and age, better periodontal status, lower DMFT and being male predicted better OHRQoL after treatment. Better task-specific self-efficacy and self-esteem, but worse plaque score predicted better end periodontal status. CONCLUSIONS: OHRQoL and periodontal status improved after periodontal treatment, and this was predicted by individual demographic and psychological factors. These factors may assist with case selection and as possible points for intervention to improve clinical and subjective outcomes of periodontal treatment.

Prevalence and factors associated with traumatic dental injuries among schoolchildren in war-torn Libya.

BACKGROUND/AIMS: No previous epidemiological study has investigated the prevalence and associated factors of traumatic dental injuries (TDIs) among Libyan children. Such information is required for the planning and evaluation of health services. The aim of this study was to assess the prevalence of TDIs and associated factors among 12-year-old schoolchildren in Benghazi, Libya. METHODS: Data for this study were collected as part of a comprehensive, cross-sectional survey investigating oral health status and treatment needs of 12-year-old schoolchildren in Benghazi, Libya, between December 2016 and May 2017. Sociodemographic information was collected through a dental health questionnaire. The children were assessed for oral health status, including TDIs according to modified World Health Organization (WHO) classification criteria, in their classroom by trained and calibrated examiners. Anthropometric measures, lip competence and overjet were all assessed and reported. History of TDIs was sought among those affected. Logistic regression models were applied for TDIs as an outcome variable. The statistical significance for all tests was ≤0.05. RESULTS: Data from 1134 participants were included in this study. TDIs were observed in 10.3% of the sample. Most of these TDIs were enamel fractures only (55.6%) and enamel and dentine fractures (35.9%). "Falling" was the most common cause of TDIs, accounting for 51% of cases. While increased overjet appeared to be associated with higher risk of TDIs (OR: 1.92; 95% CI: 1.29-2.86), being female (OR: 0.34; 95% CI: 0.22-0.53) and overweight (OR: 0.33; 95% CI: 0.13-0.83) were also associated with lower risk of having TDIs. CONCLUSIONS: This survey showed that a considerable proportion (10.3%) of 12-year-old Libyan children had TDIs, with relatively high unmet treatment needs. More efforts are required to develop effective prevention programmes and to enhance the provision of dental treatment of TDIs for Libyan children.

Measuring the symptomatic, physical, emotional and social impacts of dry mouth: A qualitative study.

OBJECTIVE: To explore the impacts of dry mouth in order to develop a comprehensive condition-specific OHRQoL measure. BACKGROUND: Dry mouth has been shown to have significant, if not more severe impacts on OHRQoL, than dental caries. Yet there remain few studies reporting on how to develop a comprehensive measure of the impact of dry mouth on OHRQoL. METHODS: This study was a qualitative study using semi-structured interviews. Data were collected from a purposive sample of 17 people with dry mouth (14 women, three men). The sample was drawn to capture a comprehensive range of impacts of dry mouth. These interviews were analysed using a framework approach informed by existing functionalist approaches to OHRQoL. RESULTS: Participants reported a huge range of symptoms associated with perceived dry mouth resulting in extensive impacts on physical, emotional (psychological) and social functioning. Dry mouth could also result in restrictions in social participation which, under some conditions, could be disabling. These impacts were modified by psychological, social and environmental factors. CONCLUSIONS: If we are to measure the impacts of oral conditions, it is important that this is done systematically and with reference to existing conceptual models of health. Current measures of the impact of dry mouth cover symptoms, discomfort and physical impacts along with some aspects of how people cope with the condition. This study proposes a more comprehensive approach that includes the full range of impacts people experience. Such an approach may enable us to focus on "downstream" and "upstream" interventions for dry mouth.

Barriers and facilitators for provision of oral health care in dependent older people: a systematic review.

OBJECTIVES: Provision of oral health care (OHC), including oral hygiene (OH) or oral/dental treatment, to dependent older people (DOP) is frequently insufficient. We aimed to assess barriers and facilitators perceived by different healthcare professionals towards providing OHC to DOP. MATERIALS AND METHODS: A systematic review was performed. Studies reporting on knowledge, attitudes, and beliefs acting as barriers and facilitators for provision of OHC were included. One database (PubMed) was searched and data extraction independently performed by two reviewers. Thematic analysis was used and identified themes translated to the domains and constructs of the theoretical domains framework (TDF) and aligned with the domains of the behavior change wheel (BCW). Analyses were stratified for the two target behaviors (providing oral hygiene and providing oral/dental treatment) and according to different stakeholders' perspective. For quantitative analysis, frequency effect sizes (FES) were calculated. RESULTS: In total, 1621 articles were identified and 41 (32 quantitative, 7 qualitative, 2 mixed method) studies included. Within these 41 studies, there were 7333 participants (4367 formal caregivers, 67 informal caregivers, 1100 managers of care, 1322 dentists, 340 DOP). Main barriers for providing OH were "lack of knowledge" (FES 65%, COM-B domain: capability, TDF domain: knowledge) and "patients refusing care" (62%, opportunity, environmental context and resources). Main facilitators were "OHC training/education" (41%, capability, skills) and "presence of a dental professional" (21%, opportunity, environmental context and resources). Main barriers for provision of dental treatment were "lack of suitable facilities for treatment/transportation of patients" (76%) and "patients refusing care" (53%) (both: opportunity, environmental context and resources). Main facilitators were "regular visiting dentist" (35%) and "routine assessment/increased awareness by staff" (35%) (both: opportunity, environmental context and resources). CONCLUSIONS: A number of barriers and facilitators for providing different aspects of OHC were identified for different stakeholders. CLINICAL RELEVANCE: Our findings help provide the evidence to develop implementation strategies for providing high-quality systematic OHC to DOP. REGISTRATION: This review was registered at Prospero (CRD42017056078).

Oral health-related quality of life after prosthodontic treatment for patients with partial edentulism: A systematic review and meta-analysis.

STATEMENT OF PROBLEM: Clinicians are currently unable to quantify the psychosocial, functional, and esthetic effects of prosthetic interventions to replace teeth. Understanding the effects of treatment to replace teeth on oral health-related quality of life (OHRQoL) is important for informed consent. A systematic review of the evidence of OHRQoL improvements with prosthodontic tooth replacement and a comparison of outcomes between treatment modalities is therefore indicated. PURPOSE: The purpose of this systematic review was to examine the OHRQoL of patients with partial edentulism after different dental prosthetic treatments. MATERIAL AND METHODS: Electronic database and manual searches were conducted to identify cohort studies and clinical trials reporting on the OHRQoL of individuals receiving implant-supported crowns (ISCs), implant-supported fixed dental prostheses (IFDPs), implant-supported removable dental prostheses (IRDPs), tooth-supported fixed dental prostheses (TFDPs), and removable partial dentures (RPDs). Two reviewers independently conducted article selection, data extraction, and quality assessment. Random-effects models were used to compare OHRQoL change scores (standardized mean change, 95% confidence intervals). RESULTS: Of the 2147 identified studies, 2 randomized controlled trials and 21 cohort studies met the inclusion criteria. Overall, studies were of low or moderate risk of bias. Pooled mean OHRQoL change ≤9 months was 15.3 for TFDP, 11.9 for RPD, and 14.9 for IFDP. Pooled standardized mean change OHRQoL change >9 months was 13.2 for TFDP and 15.8 for IFDP. Direct comparisons ≤9 months between TFDP against IFDP and RPD against IFDP significantly favored IFDP in both cases. CONCLUSIONS: TFDP and IFDP had short- and long-term positive effects on OHRQoL. RPDs positively affected OHRQoL in the short term. IFDP showed greater short-term improvement in OHRQoL than RPD and TFDP.

Perceptions of foundation dentists on minor oral surgery teaching in dental foundation training.

AIMS: The aim of this service evaluation was to explore the experiences of foundation dentists (FDs) during their dental foundation year (DFT) in the field of oral surgery and surgical extractions. METHODS: A phenomenological approach was taken aiming to explore the FDs' experiences through a qualitative design. All FDs in the region deemed eligible for the evaluation were invited to attend a semi-structured interview or answer a qualitative questionnaire when attending for their exit interview at the completion of DFT. The interviews were then transcribed and thematic analysis was undertaken. RESULTS: 79 FDs took part in the evaluation, representing 86% of trainees eligible for inclusion. Findings showed that not all FDs had the opportunity to undertake surgical extractions independently during the year. Data was analysed and 4 main themes generated when evaluating FDs' experiences; specific learning encounters, influence of the educational supervisor, supportive learning environment and ready for independent practice. CONCLUSIONS: This evaluation shows that there are a number of factors associated with FDs' experience during DFT, and not all FDs are leaving the training with a positive experience, with a query as to whether they are fulfilling the aims of training to become an "independent practitioner." It poses questions about what can be done to improve future training and what exactly does DFT need to achieve in terms of experience in surgical extractions.

Periodontitis and quality of life: What is the role of socioeconomic status, sense of coherence, dental service use and oral health practices? An exploratory theory-guided analysis on a Norwegian population.

AIM: To utilise Andersen's behavioural model for health services' use as the theoretical framework to examine direct and indirect relationships between population characteristics, oral health behaviours and periodontitis and oral health impacts. MATERIALS AND METHODS: The model was tested in a general adult population (n = 1,886) in Norway, using structural equation modelling. Socioeconomic status, sense of coherence (SOC), dental anxiety, perceived treatment need, oral health behaviours and oral health impact profile (OHIP-14) were collected through questionnaire. Periodontal examinations consisted of full-mouth recordings. RESULTS: Andersen's model explained a large part of the variance in use of dental services (58%) and oral health-related impacts (55%), and to a less extent periodontitis (19%). More social structure and stronger SOC was related to more enabling resources, which in turn was associated with more use of dental services. More use of dental services was related to more periodontitis and more periodontitis was associated with increased oral health impacts. A stronger SOC was associated with less oral impacts. There was no association between use of dental services and oral health impacts. CONCLUSIONS: The result demonstrated complex relationships between population characteristics, oral health-related behaviours and oral health outcomes. Socioeconomic factors and smoking were main predictors of periodontitis. Regular dental visiting habits did not, however, reduce the likelihood of periodontitis.

Young Adults' Experience of Appearance-Altering Orthognathic Surgery: A Longitudinal Interpretative Phenomenologic Analysis.

OBJECTIVE: To gain an experiential account of the processes of change associated specifically with orthognathic surgery. DESIGN: A qualitative design was used. Semistructured interviews were carried out with 7 participants approximately 1 week before and 6-8 weeks after surgery. The data were analyzed using interpretative phenomenologic analysis (IPA). SETTING: Participants were recruited from a NHS Dental Hospital. PARTICIPANTS: Patients aged 16 to 25 years scheduled to undergo orthognathic surgery on both the upper and lower jaws were purposively sought to participate. Seven participants aged between 18 and 25 years and who had undergone a bimaxillary osteotomy completed interviews (5 females and 2 males). RESULTS: Themes were identified in connection with the overall journey of treatment being a rite of passage; the treatment's role in raising awareness about the anomalies in appearance; the initial shock at the changes that followed surgery; the uncertainty about treatment; the impact of actual negative reactions of others; and the role of significant others in the decision-making process. CONCLUSIONS: Participants described undergoing a much more complex process of adjustment to change in appearance than has been identified elsewhere within the literature, and the study highlights the nuanced fashion in which both medical and parental communication influence patient expectation and experience of surgery. There is a need to improve communication between clinicians, families, and young adults seeking orthognathic surgery. Further studies are needed to investigate the processes associated with seeking to change facial appearance resulting from other forms of dentofacial condition.

Using classification and regression tree modelling to investigate response shift patterns in dentine hypersensitivity.

BACKGROUND: Dentine hypersensitivity (DH) affects people's quality of life (QoL). However changes in the internal meaning of QoL, known as Response shift (RS) may undermine longitudinal assessment of QoL. This study aimed to describe patterns of RS in people with DH using Classification and Regression Trees (CRT) and to explore the convergent validity of CRT with the then-test and ideals approaches. METHODS: Data from an 8-week clinical trial of mouthwashes for dentine hypersensitivity (n = 75) using the Dentine Hypersensitivity Experience Questionnaire (DHEQ) as the outcome measure, were analysed. CRT was used to examine 8-week changes in DHEQ total score as a dependent variable with clinical status for DH and each DHEQ subscale score (restrictions, coping, social, emotional and identity) as independent variables. Recalibration was inferred when the clinical change was not consistent with the DHEQ change score using a minimally important difference for DHEQ of 22 points. Reprioritization was inferred by changes in the relative importance of each subscale to the model over time. RESULTS: Overall, 50.7% of participants experienced a clinical improvement in their DH after treatment and 22.7% experienced an important improvement in their quality of life. Thirty-six per cent shifted their internal standards downward and 14.7% upwards, suggesting recalibration. Reprioritization occurred over time among the social and emotional impacts of DH. CONCLUSIONS: CRT was a useful method to reveal both, the types and nature of RS in people with a mild health condition and demonstrated convergent validity with design based approaches to detect RS.

Online support groups for head and neck cancer and health-related quality of life.

PURPOSE: To investigate the association between using online support groups (OSGs) and health-related quality of life (HRQoL), and the psychosocial factors that may influence this association among individuals with head and neck (H&N) cancer. METHOD: A sample of 199 persons with H&N cancer using four OSGs completed an online questionnaire using six pre-validated measures for social network, self-efficacy, anxiety and depression, adjustment, empowerment and quality of life. In addition, socio-demographic as well as illness-related and OSGs-related information was collected. RESULTS: Participants who had better HRQoL had been using OSGs for a longer time than those who had worse HRQoL (B = 0.07, p < 0.05). Depression and adjustment were the only direct mediators in this association, whereas self-efficacy, anxiety and empowerment appeared as indirect mediators. CONCLUSION: Participation in OSGs was found to be associated to better HRQoL either directly or indirectly through decreasing depression, anxiety and the negative adjustment behaviours and increasing self-efficacy and empowerment of the users. The study presented a potential model of pathways linking OSG use and HRQoL for those with H&N cancer. However, the model needs to be tested in future longitudinal studies and the associations proposed need to be explored in greater detail.

Development of a decision aid for children faced with the decision to undergo dental treatment with sedation or general anaesthesia.

BACKGROUND: Decision aids are tools used to help individuals faced with difficult healthcare decisions. They help patients further understand the treatment options available and encourage the sharing of information between patients and clinicians. AIM: To develop a decision aid for young patients faced with the decision to undergo dental treatment with inhalation sedation, intravenous sedation, or general anaesthesia (GA). DESIGN: Qualitative interviews with dental patients (aged 10-16 years), and their parents/guardians were used to inform the content of a draft decision aid. Following further revisions, a pilot evaluation of the decision aid was conducted. Patients referred for dental treatment with sedation or GA were recruited from a UK dental hospital. Patients (n = 15) and parents/guardians (n = 13) assigned to the intervention group received the decision aid and routine clinical counselling, whereas patients (n = 17) and parents/guardians (n = 13) in the control group only received routine clinical counselling. Participants completed measures of knowledge, decisional conflict, and dental anxiety. RESULTS: Knowledge scores were significantly higher for participants who received the decision aid when compared to standard care. There were no other significant differences between groups. CONCLUSIONS: A decision aid was successfully developed, and initial findings suggest such tools could be beneficial to dental sedation or GA patients and their parents/guardians. Further research is required on the use of such tools in primary care settings, with particular attention to the impact of the decision aid on attendance and completion rates of treatment.
