Huang X, Tao Z, Ngan P, Qin D, He H, Hua F. THE USE OF DENTAL PATIENT-REPORTED OUTCOMES AMONG COMPARATIVE OBSERVATIONAL STUDIES IN ORTHODONTICS: A METHODOLOGICAL STUDY. J Evid Based Dent Pract 2024; 24:101956. [PMID: 38401953 DOI: 10.1016/j.jebdp.2023.101956] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 10/19/2023] [Accepted: 11/07/2023] [Indexed: 02/26/2024]
Abstract
OBJECTIVE To identify and summarize the presence and characteristics of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs) within comparative observational studies published in 5 leading orthodontic journals. METHODS Electronic searching was performed to identify intervention (therapeutic or preventive) related comparative observational studies published in selected journals between 2015 and 2021. Two authors extracted the characteristics of each included study independently and in duplicate and summarized the dPROs and dPROMs used in these studies. All dPROs were classified into 2 general types (oral health-related quality of life [OHRQoL] and others), while dPROMs were divided into 3 categories (single-item questionnaires, generic multiple-item questionnaires, and specific multiple-item questionnaires). In addition, dPROMs were examined, if they evaluated the 4 dimensions of OHRQoL (oral function, orofacial pain, orofacial appearance, and psychosocial impact). RESULTS A total of 683 observational studies were eligible and included of which 117 (17.1%) used dPROs and dPROMs. Seven different dPROs (OHRQoL, patients' satisfaction with treatment, preferences, concerns, compliance, duration, and unwanted events) and 33 different dPROMs (including 8 single-item questionnaires, 11 generic multiple-item questionnaires, and 14 specific multiple-item questionnaires) were identified in these studies. OHRQoL was the most commonly used dPRO (92/117, 78.6%), while Oral Health Impact Profile 14 (OHIP-14) was the most frequently used dPROM (20/92, 21.7%). In terms of study design, cross-sectional studies had the highest proportion of dPRO usage (62/148, 41.9%), followed by cohort studies (63/505, 12.5%) and case-control studies (1/30, 3.3%). CONCLUSIONS Only one-sixth of comparative observational studies published in leading orthodontic journals could reflect patients' perspectives. Observational studies in orthodontics need to provide more patient-important information through the use of dPROs and dPROMs.

Abstract
OBJECTIVES To assess the change in Oral Health-Related Quality of Life (OHRQoL) following orthodontic treatment using the Malocclusion Impact Questionnaire (MIQ) and to test the responsiveness of MIQ to treatment-associated changes. METHODS A longitudinal prospective cohort study, in an orthodontic postgraduate centre, Kerala, India. Patients under 18 years were invited to complete the MIQ before the start of treatment (T0) and 1 month after treatment completion (T1). TheIndex of Orthodontic Treatment Need and Peer Assessment Rating (PAR) scores were assessed at both time periods as well as a global transition judgement at T1. RESULTS Two hundred and ten participants were recruited and 162 completed both questionnaires (45.1% males; 54.9% females; age = 12-18 years, mean = 16.8; SD = 1.7). There was large reduction in MIQ scores from T0 (mean = 28.1, SD = 6.1) to T1 (mean = 3.7, SD = 2.6). 53% reported a large improvement in oral health and related life quality after treatment, 32% minimal change, and 15% no change. None reported worsening in OHRQoL at T1. There was a significant positive correlation between change in MIQ score and change in PAR score (r = 0.358), pretreatment aesthetic component (rho = 0.467) and dental health component (rho = 0.491) of the index of orthodontic treatment (IOTN-DHC), and treatment time (rho = 0.502). Regression analysis revealed the change in PAR score and pretreatment IOTN-DHC to be independent predictors of change in MIQ score. Standardized effect size (4.0) and standardized response mean (2.9) were large and the minimal important difference was 7.7. Receiver operating characteristic analysis reported a high diagnostic accuracy of MIQ. CONCLUSIONS There was a significant improvement in OHRQoL following orthodontic treatment when assessed using a condition-specific measure for malocclusion. MIQ was found to be responsive to changes associated with orthodontic treatment.

Am J Orthod Dentofacial Orthop 2023; 164:314-324.e1. [PMID: 37409988 DOI: 10.1016/j.ajodo.2023.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 06/01/2023] [Accepted: 06/01/2023] [Indexed: 07/07/2023]
Abstract
INTRODUCTION This 2-arm parallel study aimed to compare and evaluate the efficiency of Hanks Herbst (HH) and Twin-block (TB) functional appliances in treating adolescents with Class II malocclusion. METHODS A parallel-group randomized controlled trial was undertaken in a single United Kingdom hospital. Eighty participants were recruited and randomized in a 1:1 ratio to receive either the HH or TB appliance. Eligibility criteria included children aged 10-14 years with an overjet of ≥7 mm without dental anomalies. The primary outcome was the time (in months) required to reduce overjet to normal limits (<4 mm). Secondary outcomes included treatment failure rates, complications and their impact on oral health-related quality of life (OHRQOL). Randomization was accomplished using electronic software with allocation concealed using sequentially numbered, opaque, and sealed envelopes. Blinding was only applicable for outcome assessment. Data were analyzed using descriptive statistics and regression analyses to detect between-group differences, including Cox regression for time to treatment success. RESULTS HH was significantly faster than TB in reducing the overjet to within normal limits (95% confidence interval [CI], -3.00 to -0.03; P = 0.046). Mean overjet reduction was more efficient with the HH than the TB appliance (ß = 1.3; 95% CI, 0.04-2.40; P = 0.04). Fifteen (37.5%) of the participants in the TB group and 7 (17.5%) in the HH group failed to complete the treatment (hazard ratio = 0.54; 95% CI, 0.32-0.91, P = 0.02). However, TB was associated with fewer routine (incidence rate ratio = 0.81; 95% CI, 0.7-0.9; P = 0.004) and emergency (incidence rate ratio = 0.1; 95% CI, 0.1-0.3; P = 0.001) visits. Chairside time was greater with the HH (ß = 2.7; 95% CI, 1.8-3.6, P = 0.001). Participants in both groups experienced complications with similar frequency. A greater deterioration in OHRQOL was found during treatment with the TB. CONCLUSIONS Treatment with HH resulted in more efficient and predictable overjet reduction than TB. More treatment discontinuation and greater deterioration in OHRQOL were observed with the TB. However, HH was associated with more routine and emergency visits. REGISTRATION ISRCTN11717011. PROTOCOL The protocol was not published before trial commencement. FUNDING No specific external or internal funding was provided. Treatment for participants was provided as part of routine orthodontic treatment in the hospital.

Abstract
Objectives The study aimed to develop a regional version of the Malocclusion Impact Questionnaire (MIQ-Malayalam) for the Malayalam-speaking Indian population. Methods The English version of MIQ was translated into Malayalam through a rigorous translation process, followed by cross-cultural adaptation. Young people aged below 18 years who were just about to start orthodontic treatment were invited to complete the Malayalam version of MIQ along with the available native version of the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The MIQ-Malayalam was readministered after 14 days to assess test-retest reliability. Treatment need was assessed normatively using the Dental Health Component of the Index of Orthodontic Treatment Need (IOTN-DHC) and subjectively using Aesthetic Component of the Index of Orthodontic Treatment Need (IOTN-AC). Results A total of 210 subjects completed the questionnaires (males = 47.2%; females = 52.8%; age = 12-17 years, mean = 15 years and 3 months; standard deviation = 1.9) and 50 completed repeat questionnaires. Internal consistency and test-retest reliability were high (Cronbach’s alpha = 0.952; Intra-class Correlation Coefficient = 0.93). Exploratory factor analysis derived 4 factors with exclusion of 1 item. There were significant differences ( P < .05) in MIQ scores between IOTN-DHC subgroups, ensuring discriminant validity. There was a high correlation between total MIQ and total PIDAQ scores (rho = 0.884), while low between total MIQ and IOTN-AC scores (rho = 0.203). Conclusion The Malayalam version of MIQ was found to be valid and reliable and can serve as a useful condition-specific measure of oral health-related quality of life.

Abstract
Objectives:
Orthodontists generally recommend avoidance of certain foods during fixed appliance (FA) treatment, based on anecdotal information. This study aimed to identify the dietary preferences and experiences of patients undergoing FA treatment as a step toward the preparation of evidence-based dietary guidelines.
Material and Methods:
Questionnaires regarding dietary preferences and experiences of patients undergoing FA treatment were applied to a convenience sample of 38 adolescents (12 M; 26 F). Open-ended responses were summarized and visualized in a world cloud generator. 5-point Likert and Visual Analog Scales (VAS) were used to record the closed-ended responses. Descriptive statistics and multivariate analysis of variance were used to analyze questionnaire findings.
Results:
Lollies, apples, and nuts frequently caused problems with FA. The most frequent reason for avoiding certain types of food was worry about appliance breakage, followed by pain and sensitivity. VAS scores indicated that toffee and caramel scored highest (65.1% F and 54.1% M) for discomfort followed by corn on the cob (64.4% F and 48.7% M) and apples (56.6% F and 55.3% M). VAS scores did not differ significantly between the sexes (P > 0.05). Nearly, a quarter of the sample reported that FA negatively affected their eating behaviors, causing pain and discomfort during eating. No sex differences (P > 0.05) were found for negative experiences with food.
Conclusion:
Dietary preferences and experiences of patients undergoing FA treatment were identified concerning a New Zealand diet profile. A future study with a larger sample size will help formulate evidence-based dietary guidelines during FA treatment.

Abstract
INTRODUCTION The need to involve patients in developing and evaluating health care interventions is now well-recognized. This study assesses and refines the Orthodontic Treatment Impact Questionnaire for use as a patient-reported outcome in an interventional clinical trial to evaluate and compare any orthodontic interventions. METHODS The face and content validity of a previously developed questionnaire were tested in 2 focus groups involving adolescents aged 11-17 years. They were wearing a range of orthodontic appliances and at different treatment stages. A similar cross-sectional convenience sample completed the questionnaire during routine appliance adjustment appointments. A Rasch model, using item response theory, was used for item reduction, assessment of the response format, and differential item functioning. Spearman's rank correlation was used to assess construct validity, Cronbach α for internal consistency and reliability, and intraclass correlation coefficient for test-retest reliability. RESULTS Seven adolescents (4 females, 3 males) were involved in the initial testing; 181 (117 females, 64 males; mean age, 14.7 ± 1.5 years) completed the questionnaire once and 41 twice. The initial measure demonstrated a misfit to the Rasch model. Ten of the original 31 items had disordered thresholds and were removed. The 5-point scale was changed to a 3-point scale. None of the participants demonstrated a misfit to the model. Construct validity (P = 0.480), internal consistency (Cronbach α = 0.827) and test-retest reliability (intraclass correlation coefficient = 0.85; 95% confidence interval, 0.73-0.92) were good. CONCLUSIONS The initial Orthodontic Treatment Impact Questionnaire was tested and modified using item response theory. The modified questionnaire demonstrated good construct validity, reliability, and internal consistency. Further testing to assess generalizability and longitudinal responsiveness is required.

Abstract
Since the World Health Organization broadened its definition of health, beyond biological boundaries, to include physical, emotional, and social wellbeing. Oral health-related quality of life (OHRQoL) became common outcome measure in clinical trials and epidemiological studies in Dentistry and Medicine. It is not surprising, therefore, to see quality of life as one of the programs of the Saudi 2030 vision. That said, it can be difficult to interpret the findings of OHRQoL research if the measures used were not appropriately adapted and validated in the population being studied. In this review article, the concept of cross-cultural adaptation of OHRQoL and its use in the Saudi context, as applied to orthodontic research, was discussed. An electronic search in PubMed and MEDLINE databases was conducted. A second search was conducted to locate methodological papers discussing cross-cultural adaptation and translations. Appraisal of relevant research was conducted to provide a better understanding of the process of adapting OHRQoL measures to assess the impact of malocclusion and dentofacial abnormalities on quality of life. This review pointed out important methodological concerns that warrant considerations during the translation and adaptation of OHRQoL measures.

Abstract
OBJECTIVES To identify the existing OHRQoL instruments for adults, describe their scope (generic or specific), theoretical background, validation type and cross-cultural adaptation. METHODS A systematic search was conducted, and articles presenting validation of OHRQoL instruments in adults were included. Data were collected about the validation type: external validation (correlations/associations); or internal validation (factor analysis/principal components analysis, item response theory); and cross-cultural adaptation. RESULTS Of 3730 references identified, 326 were included reporting 392 studies. Forty-two original instruments were found among 74 different versions, 40 generic and 34 condition-specific. Locker's theoretical framework was the predominant model. The oral health impact profile (OHIP) presented 20 versions, with OHIP-14 being the most frequent (26.8%), followed by geriatric oral assessment index (GOHAI) (14.0%), OHIP-49 (11.7%) and oral impacts on daily performances (OIDP) (9.7%). Most studies focused on external validation (65.3%), while internal validation was reported in 24.8% (n = 26) of OHIP-14 studies, 50.9% (n = 28) of GOHAI and 21.1% (n = 8) of OIDP studies. Most internal validation studies were conducted in English-speaking countries (n = 33), and cross-cultural adaptation was mostly in non-English-speaking European countries (n = 40). CONCLUSIONS Many generic and condition-specific instruments were found, but few have gone through a rigorous internal validation process or have undergone cross-cultural adaptation. This, in turn, makes it difficult for researchers to choose an appropriate measure based on known psychometric properties. OHIP-14, OIDP and GOHAI seem to be the most widely validated instruments. Equalizing measurement properties for comparability are challenging due to theoretical heterogeneity. Future studies should assess psychometric properties, explore the factorial structure and work towards a consensus on critical issues.

Abstract
PURPOSE The sociodental model integrates clinical assessment, perceived impacts of malocclusion on quality of life, and behavioural propensity when prioritising orthodontic treatment. This study compares the effect of using different instruments to measure impact-related need on the assessment of orthodontic treatment need based on the sociodental framework. MATERIALS AND METHODS In this cross-sectional study, 206 Malaysian adolescents (age: 11-18 years) were screened in orthodontic clinics to identify those with normative need, oral impacts due to malocclusion, and having high and medium-to-high behavioural propensities. The Index of Orthodontic Treatment Need classified normative need. The Psychosocial Impact of Dental Aesthetics (PIDA) questionnaire and the Condition-Specific Child-Oral Impacts on Daily Performances (CS-OIDP) index measured oral impacts. Subjects' behavioural propensities for successful treatment outcome were based on the Basic Periodontal Examination and International Caries Detection and Assessment System. Data were analysed using the McNemar test. RESULTS The response rate was 99.0%. Estimates of normative need (89.7%) were significantly reduced under the sociodental model by 65.7% (p < 0.0001) when impact-related need was measured using PIDA, and by 41.7% (p < 0.0001) when measured using CS-OIDP. The difference between the results of the two instruments in proportions of identified need for orthodontic treatment was 24.0% (p < 0.0001). CONCLUSION For Malaysian adolescents, estimates of need for orthodontic treatment when assessed with the sociodental approach were substantially lower than normative clinical assessment and depended highly on the tools selected to assess the patient's impact-related need. Health policy makers should understand the implication of adopting one instrument or the other when estimating orthodontic treatment need.

Abstract
INTRODUCTION The relationship between malocclusion, orthodontic treatment, and oral health-related quality of life (OHRQOL) is complicated, with some traits, such as increased overjet, having a potentially greater adverse effect on an adolescent's OHRQOL. The aim of this study was to evaluate the impact of malocclusion and orthodontic treatment on OHRQOL in adolescents presenting with Class II Division 1 malocclusion and explore the relationship between OHRQOL using a condition-specific and generic instrument and occlusal outcome. METHODS Two groups of adolescents were recruited from a United Kingdom university hospital: a pretreatment group of adolescents with Class II Division 1 malocclusion and a treated (posttreatment) group whose Class II Division 1 malocclusion had been corrected. Self-reported OHRQOL was assessed using the malocclusion impact questionnaire (MIQ) and the short form of Child Oral Health Impact Profile questionnaires. Occlusion severity and outcome were assessed using Peer Assessment Rating scores. RESULTS A total of 241 participants (106 male; 135 female) were recruited. MIQ scores differed significantly between the pretreatment and posttreatment groups, with scores being 11.35 times lower posttreatment than pretreatment, after adjusting for age and sex (95% confidence interval, -17.28 to -5.42; P <0.001). Females had higher total MIQ scores by 2.6 (95% confidence interval, 0.38 to 4.82), which was statistically significant (P = 0.022). There was a moderate correlation between MIQ and Peer Assessment Rating scores, but this relationship strengthened when omitting the global MIQ questions (Spearman's correlation coefficient, 0.59). CONCLUSIONS Increased overjet was associated with impaired OHRQOL using a condition-specific measure. A deeper understanding of associations between malocclusion, orthodontic treatment, and OHRQOL would benefit from longitudinal evaluation.

Monisha J, Peter E, Ani GS. Is Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) Valid for the Indian Population?-A Psychometric Study. J Int Soc Prev Community Dent 2021; 11:207-215. [PMID: 34036084 PMCID: PMC8118045 DOI: 10.4103/jispcd.jispcd_443_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 01/19/2021] [Accepted: 02/15/2021] [Indexed: 11/05/2022] Open
Abstract
Objectives: A culturally adapted and validated Oral Health-Related Quality of Life (OHRQoL) inventory helps to reliably compare patient perceptions among different populations. The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) evaluates the impact of dental aesthetics on OHRQoL. This study aimed to develop a regional version of PIDAQ (PIDAQMal) for the Indian population and to assess differences in perceptions due to malocclusion in different population groups. Materials and Methods: PIDAQMal was derived through the translation process and pilot-tested to assess test–retest reliability. Psychometric properties were tested on 285 subjects (31.2% males, 68.8% females; age range 18–25 years). Normative treatment need was assessed using Index of Orthodontic Treatment Need (IOTN)-Dental Health Component and subjective assessment using IOTN-Aesthetic Component (AC) and Perception of Occlusion Scale (POS). PIDAQMal mean domain scores were compared with those of the previously validated versions to assess difference in perceptions. Results: Internal consistency and test–retest reliability were good (Cronbach’s α = 0.83–0.88; Intraclass Correlation Coefficient = 0.74–0.91). IOTN-AC and POS scores showed significant correlation with PIDAQMal scores ensuring convergent validity (P < 0.001). Discriminant validity was confirmed by statistically significant differences (P < 0.001) in PIDAQMal scores between subjects with no treatment need and moderate/definite need. Factor analysis derived four domains with one item showing cross-loading. Difference in mean domain scores among the previously validated versions of PIDAQ confirmed socio-cultural differences in perceptions due to malocclusion. Conclusion: PIDAQMal was found to be reliable and valid for the Indian subjects and can be used as a condition-specific OHRQoL measure. Socio-cultural differences in perceptions were brought to light using the translated scale.

Enhancing validity, reliability and participation in self-reported health outcome measurement for children and young people: a systematic review of recall period, response scale format, and administration modality. Qual Life Res 2021; 30:1803-1832. [PMID: 33738710 PMCID: PMC8233251 DOI: 10.1007/s11136-021-02814-4] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/03/2021] [Indexed: 12/17/2022]
Abstract
Introduction Self-report is the gold standard for measuring children’s health-related outcomes. Design of such measures is complex and challenging. This review aims to systematically appraise the evidence on recall period, response scale format, mode of administration and approaches needed to enable children and young people < 19 years to participate in valid and reliable self-reporting of their health outcomes. Method PsycInfo, Medline, CINAHL and Embase were searched from 1 January 1990 to 15 March 2020, and citation searching undertaken in Scopus. Articles were included if they were primary research or case reports of ≥ 3 participants reporting the following: recall period, response scale selection, administration modality. Quality was assessed using QualSyst, and results synthesised narratively. This review was conducted and reported according to PRISMA guidelines. Results 81 of 13,215 retrieved articles met the inclusion criteria. Children < 5 years old cannot validly and reliably self-report health outcomes. Face scales demonstrate better psychometric properties than visual analogue or Likert scales. Computerised and paper scales generally show equivalent construct validity. Children prefer computerised measures. Children ≤ 7 years old think dichotomously so need two response options. Those > 8 years old can reliably use a 3-point scale. Conclusion The results of this review have both clinical and research implications. They can be used to inform appropriate choice of PROM for use with CYP in the clinical setting. We also give eight recommendations for future development of self-reported outcome measures for children and young people. Supplementary Information The online version contains supplementary material available at 10.1007/s11136-021-02814-4.

Abstract
OBJECTIVE The FACE-Q Craniofacial Module for children and young adults is a patient-reported outcome measure (PROM) designed to measure outcomes for patients aged 8 to 29 years with facial conditions. The aim of this study was to establish content validity of a relevant subset of the module for its use in orthodontic patients with malocclusion. SETTING AND SAMPLE POPULATION Experts in orthodontics were emailed and invited to provide feedback through a Research Electronic Data Capture survey. Patient feedback was obtained through cognitive interviews with patients aged 8 to 29 years recruited from a university-based orthodontic clinic in Canada. MATERIALS AND METHODS Expert opinion and patient interviews were used to obtain feedback on the content of 4 appearance (face, smile, teeth and jaws) and 1 function (eating and drinking) scales hypothesized to be relevant to orthodontic malocclusions, and to elicit new concepts. Interviews were audio-recorded, transcribed, and coded using a line-by-line approach. RESULTS Twenty-one experts and 15 patients participated. Expert feedback led us to drop 9, retain 40, revise 4 and add 16 new items. At the conclusion of cognitive interviews no items were dropped, 55 were retained, 5 were revised and 8 new items were added. The final set of 68 items demonstrated content validity for orthodontic patients. CONCLUSION Expert feedback and cognitive interviews enabled us to revise and refine 5 scales as part of the FACE-Q Craniofacial Module for use in orthodontic patients. These scales were included in the internationalfield-test of the FACE-Q Craniofacial Module.

Abstract
INTRODUCTION Our study objectives were to evaluate the impact of malocclusion on oral health-related quality of life (OHRQOL) of adolescents aged 11-14 years in Ile-Ife, Nigeria. METHODS Two hundred adolescents completed the Child Perceptions Questionnaire: Impact Short Form (CPQ11-14-ISF:16) and the Malocclusion Impact Questionnaire (MIQ). The Aesthetic Component of the Index of Orthodontic Treatment Need scale was used to determine malocclusion severity. The effect of sex, age, and socioeconomic class on OHRQOL were determined with the Mann-Whitney U test, Kruskal-Wallis H test, correlation tests, and multiple regression analysis using SPSS (version 22.0; IBM, Armonk, NY). Statistical significance was set at P <0.05. RESULTS The CPQ11-14-ISF:16 and MIQ identified the impact of malocclusion on OHRQOL with mean (standard deviation) scores of 12.85 (10.17) and 8.33 (7.50), respectively. Sex, socioeconomic class, and malocclusion severity had no significant effect on OHRQOL (P >0.05); however, OHRQOL differed significantly between the age groups (CPQ11-14-ISF:16, P = 0.002; MIQ, P = 0.041). Multiple regression analysis showed that age was a significant predictor of OHRQOL determined with CPQ11-14-ISF:16 (standardized coefficients B score = -0.242, P = 0.001). MIQ demonstrated good criterion validity with CPQ11-14-ISF:16 (r = 0.59, P <0.001). CONCLUSIONS Both measures CPQ11-14-ISF:16 and MIQ identified the impact of malocclusion on the OHRQOL of adolescents. Sex, socioeconomic class, and malocclusion severity did not affect OHRQOL; however, age was a significant predictor of OHRQOL. Further studies among orthodontic patient populations are desirable.

Abstract
The provision of high-quality health care involves many different aspects, including safety, effectiveness, efficiency, and patient centredness. In order for care to be truly patient centred requires patients' views being sought and considered, and this may be achieved through patient-centred research. Patient-centred research is fundamentally important in contemporary health care and has many benefits; for example, it ensures that research is relevant, identifies those aspects of care that are important to patients, provides information that is important to current and future patients, and allows the integration of patients' views regarding how services may be enhanced in the future. This paper provides an overview of how we currently involve patients in orthodontic research, what this means to the specialty and how we can enhance patient involvement in the future.

Abstract
Background Complex psychological and physiological changes occur in women’s body during pregnancy. These changes affect both oral health status and oral health-related quality of life (OHRQoL). In almost all of the previous cross-sectional design studies on pregnant women, generic OHRQoL instruments have been used to measure OHRQoL. While such instruments may be reliable, they may not be appropriate to evaluate the OHRQoL in special populations like pregnant women. The purpose of this study was to investigate the self-perceived factors affecting the OHRQoL among pregnant women. Methods In this qualitative descriptive study, twenty- seven pregnant women were recruited from four healthcare centers located in Isfahan city, Iran. The interpretative phenomenological analysis was used to collect and analyze the data. Four criteria of credibility, dependability, transferability, and confirmability were implemented through established procedures to confirm the study rigor.
Results Three major themes and six sub-themes capturing the impacts of pregnancy on women’s OHRQoL were identified. They covered all areas of life, including daily life, psychological well-being, social life, physical impact, and also barriers to utilization of dental care services. Some new domains such as “dentists’ refusal to treat pregnant women”, “negative feelings about pregnancy” and “concerns about fetal health” were found as important factors which could influence the OHRQoL during pregnancy. Conclusion The findings help to better understand the oral health issues impacting women during pregnancy and to achieve person-centered care and improved oral health outcomes in pregnant women. The conceptual framework created based on the results of this study may help health care workers and policy makers for improving the health of pregnant women.

Abstract
Introduction The objective of this study was to assess pre-treatment quality of life and the relevant clinical variables in adult patients with malocclusion in order to improve orthodontic treatment strategies. Methods The study was conducted in 240 consecutive adult patients with malocclusions divided into two groups: patients for whom an orthodontic treatment plan was considered, and patients for whom an orthognathic treatment plan was selected. Patients were examined between December 2015 and February 2017, at the School of Dental Medicine, University of Belgrade. Malocclusion severity was recorded using the Peer Assessment Rating index pre-treatment score. Skeletal malocclusion parameters were measured using lateral cephalometric radiographs. Quality of life was assessed by means of a generic questionnaire (Medical Outcomes Study Short Form-36 (SF-36)), and the disease-specific Orthognathic Quality of Life Questionnaire (OQLQ). Results There were significant differences in the mean values of the OQLQ domain scores between orthodontic and orthognathic patients. Patients for whom orthodontic treatment was planned had statistically significantly lower scores in comparison to those for whom orthognathic treatment was planned. This was the case in all OQLQ domains except for “Awareness of facial deformity”. Statistically significant correlations (p<0.05) were presented between OQLQ scores and following demographic and clinical variables: gender, age, malocclusion severity, maxillary and mandibular sagittal, maxillary vertical, and lower incisor positions, intermaxillary angle, and the Beck Depression Inventory and Beck Anxiety Inventory levels. The independent predictors for the planning of orthodontic and orthognathic treatment in patients with malocclusion were two OQLQ domains, “Facial aesthetics” and “Awareness of facial deformity”, as well as total OQLQ score, after adjustment for demographic characteristics, skeletal parameters, anxiety and depression. Conclusions Our findings suggest that patients for whom orthodontic treatment was planned demonstrated better quality of life according to the OQLQ scores in comparison to those for whom orthognathic therapy was planned.

Abstract
OBJECTIVE To translate and cross-culturally adapt the Malocclusion Impact Questionnaire (MIQ) into Chinese and to assess the psychometric properties of the Chinese version of the MIQ (MIQ/C) for use among adolescents with malocclusion in China. MATERIALS AND METHOD First, the MIQ/C was developed according to international guidelines. Then, the MIQ/C was filled out by 536 adolescents between 10 and 16 years of age. This study used exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity, internal consistency, and test-retest reliability to evaluate the psychometric properties of the MIQ/C. RESULTS Following EFA, three domains were extracted, accounting for 65.950% of the total variance. The CFA results showed that the fit indices of each factor in the three-factor model all reached the standard (chi-square/DF = 2.591, GFI = 0.919, TLI = 0.926, CFI = 0.928, RMSEA = 0.076). The scale evidenced a good relationship with the two global questions, indicating good convergent validity. The Cronbach alpha value and the intraclass correlation coefficients (ICC) value of the MIQ/C were 0.929 and 0.893, respectively. CONCLUSION The MIQ/C demonstrated good reliability and validity and can be further studied and applied in Chinese adolescents with malocclusion. CLINICAL RELEVANCE The MIQ/C can be applied to assess the psychosocial impact of malocclusion among Chinese adolescents.

Abstract
Introduction The malocclusion index questionnaire (MIQ) is widely used in research and clinical practice. To our knowledge, there are no studies of its use in Moroccan patients. Aim The objective of this study was to translate and culturally adapt the malocclusion impact questionnaire (MIQ) into Moroccan Arabic and to assess its reliability and validity among a sample of young Moroccan teenagers. The PIDAQ was cross-culturally adapted into Malay version by forward- and backward-translation processes, followed by psychometric validation. Materials and Methods The MIQ was cross-culturally adapted into Moroccan Arabic by forward- and backward-translation processes, followed by psychometric validations. The MIQ was completed by a representative sample of 94 Moroccan adolescents aged 12–17 years selected randomly from five public schools of Casablanca. Internal consistency reliability was determined from Cronbach's alpha, and the intraclass coefficient of the item scores was obtained in 1 month in a subset of 30 subjects. Data were analyzed using the Statistical SPSS software, version 16.0, SPSS Inc, Chicago, IL, USA. Results The MIQ was completed twice by each participant at one-month interval to assess test reliability; the intraclass coefficient was r = 0.958, showing an excellent reproducibility. The internal consistency demonstrated the reliability of the questionnaire with Cronbach's alpha coefficient of 0.917. The validity of the questionnaire was assessed by evaluation of the relationship between the total scores of the MIQ and normative need for orthodontic treatment according to ICON. The questionnaire showed an insignificant correlation (0.129, p < 0.05). Conclusion The Moroccan Arabic version of the MIQ was found to be reliable, whereas it has unacceptable validity according to ICON, and hence, it is unlikely to be a useful measure in orthodontic clinical trials for Moroccan adolescents.

Do malocclusion and orthodontic treatment impact oral health? A systematic review and meta-analysis. Am J Orthod Dentofacial Orthop 2020; 157:738-744.e10.

Abstract
INTRODUCTION Currently, there is limited evidence on the effects of malocclusion on oral health and whether the correction of malocclusion results in an improvement in oral health. In this review, we examined the evidence from randomized controlled trials and prospective cohort studies to provide information on any association between malocclusion and oral health and the effects of orthodontic treatment. METHODS We conducted this review in 2 parts: (1) we looked at the impact of malocclusion on oral health, and (2) we reviewed the evidence on the effect of orthodontic treatment on oral health. We searched for randomized controlled trials and prospective cohort studies. The searches were completed for articles published between January 1, 1990 and October 8, 2018 and covered Medline via Ovid, Embase, and the Cochrane Database of Systematic Reviews. References of included articles and previous systematic reviews were hand-searched. No language restrictions were applied. Two members of the study team assessed the quality of the studies using the Appraisal Tool for Cross-Sectional Studies to appraise the quality of studies in part 1. The assessment was performed at the study level. Two authors assessed each study independently, with a third author consulted when a disagreement occurred. For studies in part 2, we used the Newcastle-Ottawa scale to assess the risk of bias. When studies were included in a Cochrane review, we incorporated the risk of bias assessment. We developed data extraction forms for each area of oral health under investigation (trauma, quality of life, caries, and periodontal disease). Each author piloted the form, and we held discussions to inform any necessary refinements. We extracted data from studies into 2 × 2 tables, which provided a binary analysis of malocclusion vs the outcome of interest. If these data were not available from the published paper, then studies were not included in the meta-analysis. The authors were contacted when possible to request data in this format. RESULTS For part 1 of the study, we identified 87 studies. The overall quality was low. We could not include any of the data into an analysis because of a large variation in the nature of the studies, data collected, and outcome measures that were selected. For part 2 of the study, we found 7 studies; however, there were similar deficiencies in the data as in part 1, and thus, we could not reach any strong conclusions. CONCLUSIONS Overall, there is an absence of published evidence regarding the effects of malocclusion on oral health and the impact of orthodontic treatment on oral health.

Abstract
Background The Malocclusion Impact Questionnaire (MIQ) is a condition-specific measure that assesses the impact of malocclusion on Oral Health-Related Quality of Life (OHRQoL). The aim of this study was to cross-culturally adapt the original version of MIQ into Spanish and to assess the acceptability, reliability and validity of this version in the Chilean population. Methods The MIQ was cross-culturally adapted for the Spanish language for Chile using recommended standards for the linguistic validation of instruments. To assess its psychometric properties, a cross-sectional study was carried out with 219 children aged 10 to 16 years from public schools in Puerto Montt, Chile, who completed the Chilean versions of the MIQ (MIQCh) and the Child Perceptions Questionnaire 11–14 (CPQ11–14). The presence and severity of malocclusions was determined through the Dental Aesthetic Index by a trained dentist. The MIQ was administrated a second time two weeks later. The reliability of the scale was assessed by analysis of its internal consistency (Cronbach’s alpha) and reproducibility (Intraclass correlation coefficient – ICC). The validity of the construct was assessed by confirmatory factor analysis and known groups method. Criterion validity was assessed by calculating the Spearman correlation with the CPQ11–14. Results The content comparison of the back-translation with the original MIQ showed that all items except two were conceptually and linguistically equivalent. The cognitive debriefing showed a suitable understanding of the Chilean version. The MIQCh demonstrated good reliability, with Cronbach’s alpha coefficient of 0.85 and ICC of 0.91. A moderate correlation was found between the MIQCh and CPQ11–14 (0.58). In the known groups comparison, children who felt that their teeth bothered them and/or affected their life obtained significantly higher scores on the MIQCh. The OHRQoL was worse when the severity of the malocclusion was greater (p = 0.03). Conclusions The results support the applicability, reliability and validity of the Spanish version of MIQ for assessing OHRQoL in Chilean children with malocclusions.

Abstract
PURPOSE Several studies have shown that orthodontic anomalies may affect young people's Oral Health-Related Quality of Life (OHRQoL). The purpose the present study was to translate in the Greek language, culturally adapt and initially validate the CPQ11-14 ISF-16 for a Greek adolescent population with malocclusion. METHODS Following relevant methodological recommendations, after translation, the comprehensiveness of the Greek version of CPQ11-14 ISF-16 (CPQ11-14 ISF-16-GR) was verified in a pilot study of 20 Greek adolescents. The main study was undertaken in a sample of 200 adolescents that presented for an initial consultation at the Postgraduate Orthodontic Clinic. Cronbach's alpha was used to test internal consistency/reliability and Spearman's rho for criterion validity with the Oral Health Impact Profile (OHIP-14). Forty individuals completed the same questionnaires again after 3 weeks. Test-retest reliability was assessed using Intraclass Correlation Coefficient. Statistical tests were undertaken using SPSS (v. 24, IBM Corp., NY, USA). RESULTS The CPQ11-14 ISF-16-GR presented high internal consistency (Cronbach's alpha = 0.848 > 0.70) and very satisfactory Discrimination Index (DI = 0.47 > 0.30). Moreover, the CPQ11-14ISF-16 showed excellent criterion validity with OHIP-14 (rho = 0.719, p < 0.001). Test-retest reliability was at high levels as well (ICC = 0.719, p < 0.001). CONCLUSION The CPQ11-14 ISF-16-GR exhibits satisfactory psychometric properties to continue the investigation of OHRQoL in Greek adolescents with malocclusion. Further testing of is required in a variety of environments to increase generalizability and investigate the particular characteristics of CPQ application in malocclusion cases.

Rasch model of the child perceptions questionnaire in multi-country data. J Dent 2019; 93:103267. [PMID: 31866414 DOI: 10.1016/j.jdent.2019.103267] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2019] [Revised: 12/16/2019] [Accepted: 12/17/2019] [Indexed: 11/21/2022] Open
Abstract
OBJECTIVE To be fit-for-purpose, oral health-related quality of life instruments must possess a range of psychometric properties which had not been fully examined in the 16-item Short Form Child Perceptions Questionnaire for children aged 11 to 14 years (CPQ11-14 ISF-16). We used advanced statistical approaches to determine the CPQ's measurement accuracy, precision, invariance and dimensionality and analyzed whether age range could be extended from 8 to 15 years. METHODS Fit to the Rasch model was examined in 6648 8-to-15-year-olds from Australia, New Zealand, Brunei, Cambodia, Hong Kong, Malaysia, Thailand, Germany, United Kingdom, Brazil and Mexico. RESULTS In all but two items, the initial five answer options were reduced to three or four, to increase precision of the children's selection. Items 10 (Shy/embarrassed) and 11 (Concerned what others think) showed an 'extra' dependency between item scores beyond the relationship related to the underlying latent construct represented by the instrument, and so were deleted. Without these two items, the CPQ was unidimensional. The three oral symptoms items (4 Food stuck in teeth, 3 Bad breath and 1 Pain) were required for a sufficient person-item coverage. In three out of 14 items (21 %), Europe and South America showed regional differences in the patterns of how the answer options were selected. No differential item functioning was detected for age. CONCLUSION Except for a few modifications, the present analysis supports the combination of items, the cross-cultural validity of the CPQ with 14 items and the extension of the age range from 8 to 15 years. CLINICAL SIGNIFICANCE The valid, reliable, shortened and age-extended version of the CPQ resulting from this study should be used in routine care and clinical research. Less items and a wider age range increase its usability. Symptoms items are needed to precisely differentiate between children with higher and lower quality of life.

Abstract
OBJECTIVE To develop and validate a new psychometric tool for assessing malocclusion-related quality of life among older Indian adolescents. METHODS Item generation involved analysis of existing validated tools, followed by development of new items using various qualitative steps. A draft item pool of 41 questions was initially generated and subjected to item reduction through sequential steps involving two clinical studies to ensure reliability and validity. 431 subjects aged between 15 to 18 years took part in the validation study. Principal component analysis with varimax rotation was performed to get a psychometric tool with good factorial structure and maximum variance. RESULTS Rotated component matrix resulted in a 20 item psychometric tool containing 4 domains with a total variance of 61.57%. Inter item, item total correlation and Cronbach α (α = 0.88) ensured good reliability. A positive correlation of the scale with global question ensured convergent validity. Independent t test showed statistically significant difference (p< 0.05) between mean score of IOTN-DHC and DAI with MRQoLQ, ensuring good construct validity. CONCLUSIONS The newly developed psychometric tool is named as Malocclusion-Related Quality of Life Questionnaire (MRQoLQ) having 20 questions, including 2 socioeconomic items. The scale showed good reliability and initial validity, hence can be used among older adolescents with malocclusion to assess their malocclusion-related quality of life.

Abstract
The aim of the study was to test the validity of the Malocclusion Impact Questionnaire (MIQ) in a NZ sample and to evaluate possible cross-cultural differences in MIQ data between a NZ and a UK sample. A cross-sectional, non-random sample of young people, aged 10–16 years, attending their first appointment at the orthodontic clinic of New Zealand’s National Centre for Dentistry were asked to complete a questionnaire. This consisted of the 17 item MIQ, the short form CPQ11-14-ISF16 and two global questions. Some basic demographic and clinical data were collected. Sixty-six participants completed the questionnaire; however, the data for 2 were excluded due to the number of incomplete responses. MIQ was found to have excellent internal consistency (Cronbach’s alpha 0.924), good construct validity (Spearman’s rho, 0.661 global Q1 ‘Overall, how much do your teeth bother you?’; 0.583 global Q2 ‘Overall, how much do your teeth affect your life?’). MIQ also demonstrated good criterion validity with CPQ11-14-ISF16 (Pearson rho, 0.625). The Rasch analysis confirmed that the questionnaire performed similarly and there was no differential item functioning between the two populations. The main differences between the samples were that the young people in NZ were less concerned about their malocclusion and reported lower item-impact scores compared with the young people in the UK.

Abstract
Background Oral health related quality of life (OHRQoL) research among children and adolescents in Lithuania is just starting and no measures have been validated to date. Therefore, this study aimed to validate a Lithuanian version of the full (37 items) Child Perceptions Questionnaire (CPQ11–14) within a random sample of children aged 11 to 14. Methods A cross-sectional survey among a randomly selected sample of schoolchildren (N = 307) aged 11 to14 was conducted. An anonymous questionnaire included the full CPQ11–14 and items on global life satisfaction, oral health and oral life quality self-rating. The questionnaire was translated into Lithuanian using translation guidelines. In addition, an item on the oral pain was modified identifying the pain location. Standard tests (Cronbach’s α, construct validity and discriminant validity), supplemented with both exploratory and confirmatory factor analyses, were employed for psychometric evaluation of the instrument. The questionnaire was also tested by comparison students’ and their parents’ (N = 255) responses about oral symptoms and functional limitations. Results The modified Lithuanian version of CPQ11–14 revealed good internal consistency reliability (Cronbach’s alpha for the total scale was 0.88). The measure showed significant associations with perceived oral health status and oral well-being, as well as with global life satisfaction (p < 0.01). Discriminant validity of the instrument was approved by comparison of children’s groups defined by self-reported caries experience and malocclusion. Factor analysis revealed a complex structure with two or three factors in each of four domains of the CPQ11–14. Excellent or acceptable levels of indices of model fitting with the given data were obtained for oral symptoms, functional limitations and emotional well-being domains, but not for the social well-being domain. A significant association between child and parental responses was found (intraclass correlation coefficient was 0.56 and 0.43, correspondingly in domains of oral symptoms and functional limitations). Conclusion The Lithuanian version of the CPQ11–14 (with a modified item that identifies location of oral pain) appears to be a valid instrument to be used in further studies for measuring OHRQoL among 11 to 14 year old children in Lithuania.

Abstract
OBJECTIVE To identify the generic or disease-specific pediatric quality of life (QoL) instruments used in oral health research among children and adolescents and to provide an overview of these QoL instruments. METHODS A systematic literature search was performed with multiple databases to identify the pediatric QoL instruments used in oral health research. RESULTS The literature search yielded 872 records; from these, 16 pediatric QoL instruments were identified that had been used among children and adolescents in oral health research. Of these, 11 were oral health-specific QoL instruments and five were generic instruments. Of the 11 oral health-specific QoL instruments, none were multiattribute utility instruments (MAUI), whereas of the five generic instruments, two (Child Health Utility 9D index and EuroQoL-5D youth) were classified as an MAUI. Except for one, all pediatric QoL instruments were published after the year 2000 and the majority originated from the USA (n = 8). Of the 11 oral health-specific QoL instruments, five instruments are designed for the respondent to be a child (i.e., self-report), one uses proxy responses from a parent or guardian, and five instruments have both self and proxy versions. Of the five generic QoL instruments, one uses proxy responses and the other four instruments have both self and proxy versions. CONCLUSIONS This review identified a wide variety of pediatric oral health-specific and generic QoL instruments used in oral health research among children and adolescents. The availability of these QoL instruments provides researchers with the opportunity to select the instrument most suited to address their research question.

Abstract
Objectives To identify key measures in predicting orthodontic treatment need and to propose a self-assessment instrument that improves treatment need assessment. Subjects and methods The study included 150 randomly selected 13-year-olds. A set of measures linked to a previous study on daily life impact of malocclusion was processed, resulting in an instrument, the Demand for Orthodontic Treatment Questionnaire (DOTQ), which was analysed regarding dimensionality, reliability and validity. Dental Health Component of the Index of Orthodontic Treatment Need (IOTN-DHC) grading, representing professionally assessed treatment need, were collected from dental records. The instrument's ability to predict treatment need was tested by randomly splitting the dataset into two subgroups, using multiple regression to predict DHC in one of the groups and the prediction equation to calculate predicted DHC in the other. The outcomes were then correlated to detect the predictive power of the DOTQ, and thereby the validity of the prediction. Results The DOTQ-measures were reliable and highly inter-correlated. A high, significant correlation was found between assessed and predicted treatment need for the subgroups (r = 0.59 and 0.49), confirming the validity of the prediction. Independent variables (the measures) explained 47 per cent (R = 0.69) of the variance in treatment need. Four measures contributed significantly to the prediction, with Treatment Demand being the most powerful predictor. Limitations The age group and response rate may raise some questions regarding the generalizability of the findings. Conclusions The DOTQ is able to predict treatment need as assessed by orthodontic consultants. Its incorporation in the treatment need assessment process will acknowledge patients' self-perceived impact of malocclusion.
