A Comparison of Three Child OHRQoL Measures.

Comparing oral health-related quality of life (OHRQoL) measures can facilitate selecting the most appropriate one for a particular research question/setting. Three child OHRQoL measures Child Perceptions Questionnaire (CPQ11⁻14), the Child Oral Health Impact Profile (COHIP) and the Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) were used with 335 10- to 13-year-old participants in a supervised tooth-brushing programme in New Zealand. The use of global questions enabled their validity to be examined. Assessments were conducted at baseline and after 12 months. All three measures had acceptable internal consistency reliability. There were moderate, positive correlations among their scores, and all showed differences in the impact of dental caries on OHRQoL, with children with the highest caries experience having the highest scale scores. Effect sizes were used to assess meaningful change. The CPQ11⁻14 and the CARIES-QC showed meaningful change. The COHIP-SF score showed no meaningful change. Among children reporting improved OHRQoL, baseline and follow-up scores differed significantly for the CPQ11⁻14 and CARIES-QC measures, although not for the COHIP-SF. The three scales were broadly similar in their conceptual basis, reliability and validity, but responsiveness of the COHIP-SF was questionable, and the need to compute two different scores for the CARIES-QC meant that its administrative burden was considerably greater than for the other two measures. Replication and use of alternative approaches to measuring meaningful change are suggested.

Oral-Health-Related Quality of Life in Children and Adolescents.

This article describes child oral health-related quality of life measures and provides some examples of their use in determining the effect of clinical interventions, such as dental treatment under general anesthesia, orthodontic treatment, and treatment of orofacial clefting.

Surgical Care for School-Aged Youth With Cleft: Results From a Multicenter, Prospective Observational Study.

OBJECTIVE: To explore factors related to completion of surgery recommendations among children with cleft lip and palate (CLP) or cleft palate only (CPO). DESIGN: Multicenter prospective longitudinal cohort study (2009-2015). SETTING: Six cleft centers in the United States. PATIENTS/PARTICIPANTS: A diverse sample of 1186 youth aged 7.5 to 18.5 years with CLP or CPO and a caregiver. RESULTS: Data were collected from child-caregiver dyads at baseline and up to 3 follow-up visits. Of the 765 surgeries recommended during the study period, 83 were postponed and 597 were completed; this represents a completion rate of 78%. There were multiple reasons identified by patients for why the remaining 85 recommended surgeries were not completed. Children with nonprivate insurance were more likely to postpone recommended surgeries. Hispanic/Latino and Asian children had fewer surgeries compared to whites/Caucasians. Greater severity in rated speech differences was associated with more surgeries. Among participants who had completed all recommended surgeries, providers rated over 86% as having normal or mildly different facial appearance and 83% as having a normal or mild speech intelligibility rating. Similarly, caregivers rated 80% of facial appearance and 78% of speech positively. Approximately 25% of children had an additional surgical recommendation at the end of the study. CONCLUSIONS: The majority of surgical recommendations were completed with positive outcomes in facial appearance and speech intelligibility by provider and caregiver ratings. Several factors contributed to surgical recommendations not being completed and the results underscore the importance of examining socioeconomic and demographic disparities in surgical care.

Challenges in conducting multicentre, multidisciplinary, longitudinal studies in children with chronic conditions.

OBJECTIVES: Conducting longitudinal, multicentre, multidisciplinary research for individuals with chronic conditions can be challenging. Despite careful planning, investigative teams must adapt to foreseen and unforeseen problems. Our objective is to identify challenges encountered and solutions sought in a recently completed observational, longitudinal study of youth with cleft lip and palate as well as their caregivers. METHODS: Data for analysis were derived from a 6-year, multicentre, prospective, longitudinal study of youth with cleft conducted from 2009 to 2015 that examined oral health-related quality of life and other related clinical observations over time in youth who had cleft-related surgery compared to those who did not. Youth and their caregivers participating in this study were followed at one of six geographically diverse, multidisciplinary cleft treatment centres in the USA. RESULTS: Establishing effective communication, ensuring protocol adherence, safeguarding data quality, recognizing and managing differences across sites, maximizing participant retention, dealing with study personnel turnover, and balancing/addressing clinical and research tasks were particularly exigent issues that arose over the course of the study. Attending to process, ongoing communication within and across sites, and investigator and clinician commitment and flexibility were required to achieve the stated aims of the research. CONCLUSION: Studying children with cleft and their caregivers over time created both foreseen and unforeseen challenges. Solutions to these challenges are presented to aid in the design of future longitudinal research in individuals with chronic conditions.

Oral health-related quality of life in youth receiving cleft-related surgery: self-report and proxy ratings.

PURPOSE: This paper evaluated the impact of cleft-related surgery on the oral health-related quality of life (OHRQoL) of youth with cleft over time. METHODS: Data were derived from a 5-year, multi-center, prospective, longitudinal study of 1196 youth with cleft lip and/or palate and their caregivers. Eligible youth were between 7.5 and 18.5 years old, spoke English or Spanish, and were non-syndromic. During each observational period, which included baseline, and 1- and 2-year post-baseline follow-up visits, youths and their caregivers completed the Child Oral Health Impact Profile, a validated measure of OHRQoL. Multilevel mixed-effects models were used to analyze the effects of receipt of craniofacial surgery on OHRQoL over time. RESULTS: During the course of this study a total of 516 patients (43 %) received at least one surgery. Youth in the surgery recommendation group had lower self- (ß = -2.18, p < 0.05) and proxy-rated (ß = -2.92, p < 0.02) OHRQoL when compared to non-surgical self- and proxy-rated OHRQoL at baseline. Both surgical and non-surgical youth (ß = 3.73, p < 0.001) and caregiver (ß = 1.91, p < 0.05) ratings of OHRQoL improved over time. There was significant incremental improvement (time × surgery interaction) in self-reported OHRQoL for youth postsurgery (ß = 1.04, p < 0.05), but this postsurgery increment was not seen in the caregiver proxy ratings. CONCLUSIONS: Surgical intervention impacts OHRQoL among youth with cleft. Youth who were surgical candidates had lower baseline self- and caregiver-rated OHRQoL when compared to non-surgical youth. Youth who underwent cleft-related surgery had significant incremental improvements in self-rated but not caregiver (proxy)-rated OHRQoL after surgery.

Minimally important difference of the Child Oral Health Impact Profile for children with orofacial anomalies.

BACKGROUND: The Child Oral Health Impact Profile (COHIP) is an instrument designed to measure the self-reported oral health-related quality of life of children between the ages of 8 and 15, including domains for oral health, functional well-being, social-emotional well-being, school environment and self-image. The purpose of this study was to estimate the minimally important difference (MID) of the COHIP for patients with cleft lip/palate. METHODS: Data from a 6-year, prospective, longitudinal cohort study of children with cleft lip/palate were analyzed to estimate the MID. Analysis was restricted to patients with data at baseline and first follow-up and not receiving a surgical intervention in the intervening years (N = 281). MIDs were estimated via the anchor-based method, using the Global Assessment of Change, and the effect size distribution method. RESULTS: Based on the distributional method, the minimally important differences were 0.16 (oral health), 0.12 (functional), 0.22 (social-emotional), 0.21 (school environment) and 0.19 (self-image). MID anchor estimates for COHIP domains ranged from -0.32 to 0.84. The anchor-based and effect size MID estimates for the overall COHIP score were 2.95 and 0.25, respectively. CONCLUSION: The minimally important difference of the Child Oral Health Impact Profile is recommended for interpreting clinically meaningful change in patients with cleft lip/palate.

Surgeon's and Caregivers' Appraisals of Primary Cleft Lip Treatment with and without Nasoalveolar Molding: A Prospective Multicenter Pilot Study.

BACKGROUND: Despite the increasing use of nasoalveolar molding in early cleft treatment, questions remain about its effectiveness. This study examines clinician and caregiver appraisals of primary cleft lip and nasal reconstruction with and without nasoalveolar molding in a nonrandomized, prospective, multicenter study. METHODS: Participants were 110 infants with cleft lip/palate (62 treated with and 48 treated without nasoalveolar molding) and their caregivers seeking treatment at one of six high-volume cleft centers. Using the Extent of Difference Scale, standard photographs for a randomized subset of 54 infants were rated before treatment and after surgery by an expert clinician blinded to treatment group. Standard blocked and cropped photographs included frontal, basal, left, and right views of the infants. Using the same scale, caregivers rated their infants' lip, nose, and facial appearance compared with the general population of infants without clefts before treatment and after surgery. Multilevel modeling was used to model change in ratings of infants' appearance before treatment and after surgery. RESULTS: The expert clinician ratings indicated that nasoalveolar molding-treated infants had more severe clefts before treatment, yet both groups were rated equally after surgery. Nasoalveolar molding caregivers reported better postsurgery outcomes compared with no-nasoalveolar molding caregivers (p < 0.05), particularly in relation to the appearance of the nose. CONCLUSIONS: Despite having a more severe cleft before treatment, infants who underwent nasoalveolar molding were found by clinician ratings to have results comparable to those who underwent lip repair alone. Infants who underwent nasoalveolar molding were perceived by caregivers to have better treatment outcomes than those who underwent lip repair without nasoalveolar molding. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Oral Health-Related Quality of Life and Self-Rated Speech in Children With Existing Fistulas in Mid-Childhood and Adolescence.

OBJECTIVE: To report the associations of oro-nasal fistulae on the patient-centered outcomes oral health-related quality of life and self-reported speech outcomes in school aged-children. DESIGN: Prospective, nonrandomized multicenter design. SETTING: Six ACPA-accredited cleft centers. PARTICIPANTS: Patients with cleft palate at the age of mixed dentition. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Prevalence of fistula and location of fistula (Pittsburgh Classification System). Patients were placed into one of three groups based on the following criteria: alveolar cleft present, no previous repair (Group 1); alveolar cleft present, previously repaired (Group 2); no congenital alveolar cleft (Group 3). Presence of fistula and subgroup classification were correlated to oral health-related quality of life (Child Oral Health Impact Profile [COHIP]) and perceived speech outcomes. RESULTS: The fistula rate was 5.52% (62 of 1198 patients). There was a significant difference in fistula rate between the three groups: Group 1 (11.15%), Group 2 (4.44%), Group 3 (1.90%). Patients with fistula had significantly lower COHIP scores (F1,1188 = 4.79; P = .03) and worse self-reported speech scores (F1,1197 = 4.27; P = .04). Group 1 patients with fistula had the lowest COHIP scores (F5,1188 = 4.78, P =.02) and the lowest speech scores (F5,1188 = 3.41, P = .003). CONCLUSIONS: Presence of palatal fistulas was associated with lower oral health-related quality of life and perceived speech among youth with cleft. The poorest outcomes were reported among those with the highest fistula rates, including an unrepaired alveolar cleft.

Caregiver responses to early cleft palate care: A mixed method approach.

OBJECTIVE: This study sought to understand caregivers' (CGs') responses to early cleft lip/palate care for their infants. METHOD: A prospective, mixed methods multicenter longitudinal study was conducted among CGs (N = 118) seeking treatment for their infants' cleft lip and palate or cleft lip only at 1 of 6 cleft treatment centers in the United States. Participants were in 1 of 2 treatment groups: traditional care only or nasoalveolar molding (NAM) plus traditional care. The CGs completed semistructured interviews and standardized questionnaires assessing psychosocial well-being and family impact at 3 time points: the beginning of treatment (∼1 month of age), prelip surgery (∼3-5 months of age), and postpalate surgery (∼12-13 months of age). Multilevel modeling was used to longitudinally assess CGs' psychosocial outcomes. RESULTS: Although the first year was demanding for all CGs, NAM onset and the child's lip surgery were particularly stressful times. CGs used optimism, problem-solving behavior, and social support to cope with this stress. Qualitatively, CGs' ability to balance cleft treatment demands with their psychosocial resources and coping strategies influenced family adaptation. Qualitative and quantitative results indicated CGs of NAM-treated infants experienced more rapid declines in anxiety and depressive symptoms and better coping skills over time than CGs whose infants had traditional care. CONCLUSION: CGs of NAM-treated infants experienced more positive psychosocial outcomes than CGs whose infants had traditional care. Results from the mixed model support the family adjustment and adaptation response model as used in pediatric chronic condition research.

Communication Skills in Dental Students: New Data Regarding Retention and Generalization of Training Effects.

Previous studies have shown that a communications program using patient instructors (PIs) facilitates data-gathering and interpersonal skills of third-year dental students. The aim of this study was to address the question of whether those skills are retained into the students' fourth year and generalized from the classroom to the clinic. In the formative training phase, three cohorts of D3 students (N=1,038) at one dental school received instruction regarding effective patient-doctor communication; interviewed three PIs and received PI feedback; and participated in a reflective seminar with a behavioral science instructor. In the follow-up competency phase, fourth-year students performed two new patient interviews in the clinic that were observed and evaluated by clinical dental faculty members trained in communications. Mean scores on a standardized communications rating scale and data-gathering assessment were compared over training and follow-up sessions and between cohorts with a linear mixed model. The analysis showed that the third-year students' mean communication and data-gathering scores increased with each additional encounter with a PI (p<0.05) and that communication scores were not only maintained but increased during the fourth-year follow-up competency evaluations (p<0.05). Based on changes in the communications curriculum, prior instruction facilitated the students' clinical communication performance at baseline (p<0.05). This study suggests that the current Clinical Communications program improved students' data-gathering and interpersonal skills. Those skills were maintained and generalized through completion of the D4 students' summative competency performance in a clinical setting.

Coping With Cleft: A Conceptual Framework of Caregiver Responses to Nasoalveolar Molding.

OBJECTIVE: To present a conceptual framework of caregiver coping and adaptation to early cleft care using nasoalveolar molding. DESIGN: In-depth interviews were conducted at three time points with caregivers of infants with cleft lip or cleft lip and palate whose children had nasoalveolar molding to treat their cleft. Qualitative data were analyzed using modified grounded theory. RESULTS: Most caregivers expressed initial apprehension and anxiety about the responsibilities of care associated with nasoalveolar molding (e.g., changing and positioning tapes, cleaning the appliance). In subsequent interviews, caregivers often reported positive feelings related to their active participation in their child's treatment for cleft. These positive feelings were associated with increased self-esteem and feelings of empowerment for the caregivers. Although caregivers also identified burdens associated with nasoalveolar molding (e.g., stress related to lip taping, concerns about the appliance causing sores in their child's mouth, travel to weekly appointments), they tended to minimize the impact of these issues in comparison with the perceived benefits of nasoalveolar molding. CONCLUSIONS: Despite the increased burden of care, many caregivers of infants with cleft used nasoalveolar molding as a problem-focused coping strategy to deal with their child's cleft. Completing nasoalveolar molding was often associated with positive factors such as increased empowerment, self-esteem, and bonding with their infant.

Parent-Reported Family Functioning Among Children With Cleft Lip/Palate.

OBJECTIVE: To examine family functioning related to sociodemographic and clinical characteristics in youth with cleft lip and/or palate (CL/P). DESIGN: Cross-sectional, multi-site investigation. SETTING: Six U.S. cleft centers. PATIENTS/PARTICIPANTS: A diverse sample of 1200 children with CL/P and their parents. MAIN OUTCOME MEASURE: Parents completed the Family Environment Scale (FES), which assesses three domains of family functioning: cohesion (or closeness), expressiveness (open expression of feelings), and conflict. Demographic and clinical characteristics were also assessed including race, ethnicity, type of insurance, and surgical recommendations. RESULTS: The FES scores for families seeking team evaluations for their youth with CL/P (mean age = 11.6 years) fall within the average range compared with normative samples. Families receiving surgical recommendations for their youth also had FES scores in the average range, yet families of children recommended for functional surgery reported greater cohesion, expressiveness, and less conflict compared with those recommended for aesthetic surgery (P < .05). For cohesion and expressiveness, significant main effects for race (P = .012, P < .0001, respectively) and ethnicity (P = .004, P < .0001, respectively) were found but not for their interaction. No significant differences were found on the conflict domain. Families with private insurance reported significantly greater cohesion (P < .001) and expressiveness (P < .001) than did families with public insurance. CONCLUSIONS: Family functioning across domains was in the average range. However, observed differences by race, ethnicity, type of insurance, and surgical recommendation may warrant consideration in clinical management for patients and families.

Assessment of presurgical clefts and predicted surgical outcome in patients treated with and without nasoalveolar molding.

Obtaining an esthetic and functional primary surgical repair in patients with complete cleft lip and palate (CLP) can be challenging because of tissue deficiencies and alveolar ridge displacement. This study aimed to describe surgeons' assessments of presurgical deformity and predicted surgical outcomes in patients with complete unilateral and bilateral CLP (UCLP and BCLP, respectively) treated with and without nasoalveolar molding (NAM). Cleft surgeon members of the American Cleft Palate-Craniofacial Association completed online surveys to evaluate 20 presurgical photograph sets (frontal and basal views) of patients with UCLP (n = 10) and BCLP (n = 10) for severity of cleft deformity, quality of predicted surgical outcome, and likelihood of early surgical revision. Five patients in each group (UCLP and BCLP) received NAM, and 5 patients did not receive NAM. Surgeons were masked to patient group. Twenty-four percent (176/731) of surgeons with valid e-mail addresses responded to the survey. For patients with UCLP, surgeons reported that, for NAM-prepared patients, 53.3% had minimum severity clefts, 58.9% were anticipated to be among their best surgical outcomes, and 82.9% were unlikely to need revision surgery. For patients with BCLP, these percentages were 29.8%, 38.6%, and 59.9%, respectively. Comparing NAM-prepared with non-NAM-prepared patients showed statistically significant differences (P < 0.001), favoring NAM-prepared patients. This study suggests that cleft surgeons assess NAM-prepared patients as more likely to have less severe clefts, to be among the best of their surgical outcomes, and to be less likely to need revision surgery when compared with patients not prepared with NAM.

Prevalence of persistent pain 3 to 5 years post primary root canal therapy and its impact on oral health-related quality of life: PEARL Network findings.

INTRODUCTION: The frequency of persistent pain 3-5 years after primary root canal therapy and its impact on the patient's perceived oral health-related quality of life was determined in a practice-based research network. METHODS: All patients presenting to participating network practices who received primary root canal therapy and restoration for a permanent tooth 3-5 years previously were invited to enroll. Persistent pain was defined as pain occurring spontaneously or elicited by percussion, palpation, or biting. The patient also completed an oral health-related quality of life questionnaire (Oral Health Impact Profile-14). RESULTS: Sixty-four network practices enrolled 1323 patients; 13 were ineligible, 12 did not receive a final restoration, and 41 were extracted, leaving 1257 for analysis. The average time to follow-up was 3.9 ± 0.6 years. Five percent (63/1257) of the patients reported persistent pain, whereas 24 of 63 (38%) exhibited periapical pathosis and/or root fracture (odontogenic pain). No obvious odontogenic cause for persistent pain was found for 39 of 63 (62%). Teeth treated by specialists had a greater frequency of persistent pain than teeth treated by generalists (9.3% vs 3.0%, respectively; P < .0001). Sex, age, tooth type, type of dentist, and arch were not found to be associated with nonodontogenic persistent pain; however, ethnicity and a preoperative diagnosis of pulpitis without periapical pathosis were. Patients reporting pain with percussion tended to experience pain with other stimuli that negatively impacted quality of life including oral function and psychological discomfort and disability. CONCLUSIONS: These results suggest that a small percentage (3.1%) of patients experience persistent pain not attributable to odontogenic causes 3-5 years after primary root canal therapy that may adversely impact their quality of life.

International confederation for cleft lip and palate and related craniofacial anomalies task force report: holistic outcomes.

Objective : This paper describes the process and outcomes of the 2013 American Cleft Palate-Craniofacial Association task force on Holistic Outcomes. The goals and membership of the task force are presented. Methods : Using internet communication, the group introduced themselves, shared ideas and information related to holistic assessment and implementation of using a validated holistic measure, the Child Oral Health Impact Profile (COHIP) at participating international sites. Results : Data from the sites were analyzed using descriptive statistics. Administration of the COHIP was successful. It varied from self-completion as well as verbal presentation due to language differences and a function of the short time period to complete collection. Additionally qualitative comments were reported by the task force site directors. Conclusions : Future directions for holistic assessment and communication among task force members and sites were discussed at the Congress and are presented in this report.

Examining factors associated with oral health-related quality of life for youth with cleft.

BACKGROUND: Patient-reported quality-of-life outcomes in cleft lip-cleft palate treatment are critical for evidence-based care. Scant data exist analyzing treatment from the patient's perspective. The authors examined the interrelationship among variables associated with oral health-related quality of life among youth with cleft. METHODS: As part of an ongoing longitudinal study, clinical evaluations and research questionnaire packets were completed before surgical recommendations were made (baseline). Participants completed the Child Oral Health Impact Profile, a validated oral health-related quality-of-life measure for children with cleft. During the baseline clinical evaluations, plastic surgeons determined whether surgical interventions were recommended within the year (expert determination represents a greater degree of current clinical need). General linear models incorporating surgical recommendation, gender, and age were fit for each subscale of and for the total Child Oral Health Impact Profile. Significant interaction terms were evaluated for their effect on the subscale. RESULTS: Baseline assessments were obtained from 1200 participants (mean, 11.8 years; 57 percent male). Participants with a surgical recommendation had lower quality of life on all but the self-esteem subscale compared with those without a surgical recommendation (p < 0.002). Two subscales had statistically significant age-sex interactions (p < 0.003), whereas another subscale had a statistically significant surgery by sex interaction term (p = 0.027). CONCLUSIONS: Overall, youth for whom surgery is currently recommended had lower oral health-related quality-of-life scores on the Child Oral Health Impact Profile Total scale than those with no surgical recommendation; older female subjects had lower quality-of-life scores than male subjects. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Examination of a theoretical model for oral health-related quality of life among youths with cleft.

OBJECTIVES: We evaluated relationships among physical and psychological indicators and oral health-related quality of life (OHRQOL) in youths with cleft. METHODS: We recruited youths aged 7 to 18 years with cleft palate (n = 282) or cleft lip and palate (n = 918) and their caregivers into a 5-year observational investigation at 6 US treatment centers from 2009 to 2011. At baseline, youths completed surveys to assess psychological status. After clinical evaluation, 433 youths received a recommendation for surgery. We developed structural models from the baseline data incorporating age, gender, race, and cleft diagnosis to examine direct relationships between depressive symptoms and, in separate models, self-concept and sense of mastery and OHRQOL. Subsequent models examined the possible mediating effect of surgical recommendation. RESULTS: Depressive symptoms were negatively and self-concept and self-efficacy were positively associated with OHRQOL. Surgical recommendation appeared to mediate the effect of psychological well-being, but not depression, on OHRQOL, even after adjustment for cleft diagnosis. In some models, individual-level characteristics were significant. CONCLUSIONS: Path analyses support the theoretical model and underscore the importance of examining positive psychosocial characteristics such as resiliency and self-concept in this patient population.

Evaluation of the similarities and differences in response patterns to the Pediatric Quality of Life Inventory and the Child Oral Health Impact Scores among youth with cleft.

PURPOSE: To examine (a) the pattern of responses to a generic health-related quality of life (HRQL) measure (Pediatric Quality of Life Inventory--PedsQL) and an oral health-related quality of life (OHRQoL) measure (Child Oral Health Impact Profile--COHIP), and (b) the associations of these scores with surgical recommendation status among youth with cleft. METHODS: Cross-sectional data (baseline) regarding clinicians' surgical recommendations and quality of life (QoL) measures were examined from an ongoing observational study on treatment outcomes. Approximately one-third of the racially and geographically diverse sample (N = 1,200; mean = 11.6 years) received surgical recommendations to correct either visible (aesthetic) or invisible (functional) defects. Effect sizes were used to quantify differences in QoL based on surgical recommendation and to compare the sensitivity of the PedsQL and COHIP subscales. Using Pearson coefficients, the scores of those recommended for surgery were compared with those without a surgical recommendation. RESULTS: A moderate correlation (0.52) was found between the total scores on the PedsQL and COHIP (p < 0.0001). Subscale correlations between the QoL measures ranged from 0.19 to 0.48 with the strongest correlation between the PedsQL Emotional (r = 0.47) and COHIP Socioemotional Well-being subscale. The effect size for the COHIP Socioemotional Well-being (0.39) was larger than the PedsQL Social/Emotional (0.07/0.11) subscale (Z = 5.30/Z = 4.64, p < 0.0001, respectively), and the total COHIP (0.31) was significantly greater than the total PedsQL scale (0.15, z = 2.65, p = 0.008). CONCLUSIONS: A significant relationship was found between generic HRQL, OHRQoL, and surgical needs among youth with cleft with the COHIP having larger effect sizes than the PedsQL among surgical groups.

Reliability and validity testing for the Child Oral Health Impact Profile-Reduced (COHIP-SF 19).

OBJECTIVES: This study assessed the reliability and validity of the Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) from the validated 34-item COHIP. METHODS: Participants included 205 pediatric, 107 orthodontic, and 863 patients with craniofacial anomalies (CFAs). Item level evaluations included examining content overlap, distributional properties, and use of the response set. Confirmatory factor analysis identified potential items for deletion. Scale reliability was assessed with Cronbach's alpha. Discriminant validity of the COHIP-SF 19 was evaluated as follows: among pediatric participants, scores were compared with varying amounts of decayed and filled surfaces (DFS) and presence of caries on permanent teeth; for orthodontic patients, scores were correlated with anterior tooth spacing/crowding; and for those with CFA, scores were compared with clinicians' ratings of extent of defect (EOD) for nose and lip and/or speech hypernasality. Convergent validity was assessed by examining the partial Spearman correlation between the COHIP scores and a standard Global Health self-rating. Comparisons between the COHIP and the COHIP-SF 19 were completed across samples. RESULTS: The reduced questionnaire consists of 19 items: Oral Health (five items), Functional Well-Being (four items), and a combined subscale named Socio-Emotional Well-Being (10 items). Internal reliability is ≥ 0.82 for the three samples. Results demonstrate that the COHIP-SF 19 discriminates within and across treatment groups by EOD and within a community-based pediatric sample. The measure is associated with the Global Health rating (P < 0.05), thereby indicating convergent validity. CONCLUSIONS: Reliability and validity testing demonstrate that the COHIP-SF 19 is a psychometrically sound instrument to measure oral health-related quality of life across school-aged pediatric populations.
