VPI Effects On Life Outcomes Research Articles

Quality of Life and Psychosocial Outcomes Among Children With Cleft Differences.

Introduction Velopharyngeal insufficiency (VPI) and craniofacial differences can lead to diminished speech and swallowing function resulting in communication and social challenges throughout childhood. To monitor changes in patients' psychosocial health and velopharyngeal function, the Pediatric Symptom Checklist (PSC) and Velopharyngeal Insufficiency Effects on Life Outcomes (VELO) survey tools can be utilized. This study aimed to investigate the relationship between VPI quality-of-life outcomes and psychosocial disturbances through a comparative analysis of PSC and VELO parental surveys among children followed by a craniofacial team. Methods A retrospective chart review was completed using data from asingle, multidisciplinary cleft and craniofacial team. Previously completed parental survey responses between 2010 and 2022 were collated and resultswere analyzed using a Spearman's rank correlation test (rs). Results There were 89 subjects who completed both surveys on the same day (n = 148 survey pairs (s)). Patients aged three to five years old (s = 88) had a mean VELO of 17.9 (0-65) and a mean PSC of 7.9 (0-27), while patients aged six to eight years old (s = 60) had a mean VELO of 16.6 (0-74) and a mean PSC of 12.0 (0-37). The strongest correlation observed for both age groups was between the total PSC and VELO Speech Limitations sub-scores (three to five years old: rs = 0.537, p < 0.001; six to eight years old: rs = 0.330, p = 0.010). Similarly, children in the six- to eight-year-old group with cleft lip and palate showed a correlation between the total PSC and VELO Speech Limitations (rs = 0.583, p < 0.001). Conclusion This study suggests arelationship between PSC and VELO scores among childrenages three to eight years old with cleft differences and demonstrates that specific domains within theVELO questionnaireshould be considered as being associated with a higher riskfor psychosocial impairment. Specifically, higher VELO Speech Limitations sub-scores may portend a greater risk for poor psychosocial outcomes supporting the importance of early interventions in this group.

Correlation of the Chinese velopharyngeal insufficiency-related quality of life instrument and speech in subjects with cleft palate.

ObjectiveAssessment of the hypothesized correlation between the Chinese Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument and measured speech parameters.MethodsA cross‐sectional study was conducted in the Oral Clefts Center of West China Hospital of Stomatology between January 2019 and December 2019. Speech parameters including speech intelligibility deficit, VPI severity, VP gap, and need for speech therapy were evaluated by speech‐language pathologists. All patients and their parents completed the VELO instrument. The correlation between aforementioned speech parameters and VELO scores was examined utilizing Spearman correlation coefficients. The reliability of VELO test–retest and parent proxy assessment was estimated utilizing intraclass correlation coefficients (ICC). A receiver operating characteristic curve was used to calculate the cutoff VELO score.ResultsOne hundred and forty patients with their parents were enrolled. The mean age was 12.58 ± 3.72 years. Both parent and youth VELO total and domain scores recorded moderate to strong correlations with all speech parameters (r > −.40, P ˂ .001) except the swallowing domain. Most VELO domain items have shown significant correlations with at least one speech parameter. Moreover, the scales of all speech parameters showed different VELO scores (P ˂ .001). The ICC reported test–retest correlation >.73 in all domains, and parent proxy correlation >.63 in most domains except the emotional and perception domains. The cutoff VELO score was 79.04 in parent version and 85.77 in youth version.ConclusionsThe correlations between VELO scores and measured speech parameters have provided evidence for test–retest and parent proxy reliability and criterion and construct validity of the Chinese version of the VELO instrument. A VELO score ≥79.04 (in parent version) or ≥85.77 (in youth version) mostly reflects proper speech‐related quality of life. Hence, this instrument could serve as a simple tool to help clinicians understand the social, emotional, and physical influences of VPI.

Quality of Life in Patients With Velopharyngeal Insufficiency in West China.

This study aimed to investigate the quality of life (QOL) of patients with cleft lip and palate and velopharyngeal insufficiency (VPI) in relation to sex, age, age at initial cleft lip surgery, and age at initial cleft palate surgery. This is a cross-sectional study. The study was conducted in a tertiary medical center. The participants were caregivers of 72 patients with cleft lip and palate and VPI aged 4 to 20 years. Participants completed the Chinese version of the caregiver report of the VPI Effects on Life Outcomes (VELO) questionnaire. The Mann-Whitney U test was used to evaluate the patients' sex, age, age at initial cleft lip repair, and age at initial cleft palate repair in relation to VELO total score and domains. Spearman correlation analysis was completed including all study variables. Associations between the study variables and the VELO total score were tested using a generalized linear mixed model. In the univariate analysis, patients' age and age at initial cleft palate surgery influenced the QOL of patients with VPI. There were no differences in the VELO total score or domains based on sex or age at first cleft lip surgery. In the generalized linear mixed model, patients older than 8 years had higher VELO total scores. By caregiver report, the QOL of patients under age 8 years with VPI was lower than older patients. In addition, the caregiver impact domain was higher for parents of children who had their initial cleft palate surgery at age 2 years or younger.

Is High-Intensity Speech Intervention Better? A Comparison of High-Intensity Intervention Versus Low-Intensity Intervention in Children With a Cleft Palate.

Purpose The purpose of this study was to compare the effect of speech intervention provided with a low intensity with speech intervention provided with a high intensity on the speech and health-related quality of life (HRQoL) in Dutch-speaking children with a cleft palate with or without a cleft lip (CP ± L) between 4 and 12 years. Method A longitudinal, prospective, randomized controlled trial with a multiple baseline design was used. Twelve children with a CP ± L (M age = 8.0 years, SD = 1.54) were divided into two groups using block randomization stratified by age and gender: One group received low-intensity speech intervention (LISI; n = 6) and one group received high-intensity speech intervention (HISI; n = 6). Children in the LISI group received intervention with a session duration of 1 hr, a dose frequency of 1 session per week, and a total intervention duration of 10 weeks. Children in the HISI group received intervention with a session duration of 1 hr, a dose frequency of 5 sessions per week, and a total intervention duration of 2 weeks. The cumulative intervention intensity was kept constant. Both groups received identical therapy programs provided by the same experienced speech therapist. Perceptual speech assessments were performed on baseline and posttreatment data points. Changes in HRQoL were assessed using the Velopharyngeal Insufficiency Effects on Life Outcomes (VELO) questionnaire. Both groups were compared over time using (generalized) linear mixed models. Results No significant Time × Group interactions were observed for the percentage of correctly produced consonants at the word and sentence levels, indicating no differences in evolution over time among the two groups. The variables speech understandability, speech acceptability, and the total VELO scores significantly improved following HISI, but not following LISI. Conclusions Children in the HISI group made equal and, for some variables, even superior progress in only 2 weeks of therapy compared to children in the LISI group who received 10 weeks of therapy. HISI is a promising strategy to improve speech outcomes and HRQoL in a shorter time period.

Nepali Linguistic Validation of the Velopharyngeal Insufficiency Effects on Life Outcomes Instrument: VELO-Nepali.

To translate and validate the velopharyngeal insufficiency (VPI) effects on life outcomes (VELO) instrument into Nepali, and test its internal consistency and validity. Quality-of-life instrument translation and validation. Community served by Nepal's craniofacial referral hospital. Twenty-three postpalatoplasty children with VPI, 19 family guardians of VPI cases, and 29 non-VPI controls. The VELO instrument was translated to Nepali by 2 independent bilingual translators, reconciled, backward-translated, compared, and modified using patient cognitive interviews. All VPI children, guardians, and controls completed the VELO-Nepali. The VELO internal consistency was evaluated using Cronbach α coefficient. Concurrent validity and discriminant validity were assessed using 2-sample t test: assuming unequal variances. The VELO was translated and optimized using cognitive interviews. The VELO-Nepali demonstrated excellent internal consistency, with Cronbach α coefficients of 0.93, 0.94, and 0.90 for VPI cases, guardians of VPI cases, and non-VPI controls, respectively. The VELO-Nepali exhibited strong discriminant validity between VPI cases ( = 45.4, standard deviation [SD] = 22.1) and non-VPI controls ( = 84.9, SD = 12.3), (P < .001). The VELO-Nepali showed strong concurrent validity with similarities in VPI case scores ( = 45.4, SD = 22.1), and guardian scores ( = 52.9, s = 22.8; P = .473). The translated VELO-Nepali demonstrates strong internal consistency, discriminant validity, and concurrent validity, and can assess quality of life for Nepali VPI patients. This instrument represents the first VPI quality of life assessment validated in Nepali, and supports the feasibility of its implementation in other low- and low-middle-income countries.

The relationship between health-related quality of life and speech in patients with cleft palate

IntroductionIn health-care, current efforts focus on providing patient-centered care. Specifically for patients with velopharyngeal insufficiency, and by extent patients with cleft palate, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire (Skirko et al., 2012; 2013) allows the clinician to map the impact of speech and swallowing difficulties on the patient's health-related quality of life (HRQoL). The current study evaluated the hypothesized association between this speech-related HRQoL measure and perceptually and instrumentally assessed speech variables, to provide evidence for the construct validity of the Dutch version of the VELO questionnaire. Materials and methodsThirty participants, twenty-five patients with cleft palate and five controls, were enrolled. Perceptual speech assessment was conducted following the recently developed Belgian Dutch outcome tool for perceptual speech assessment in patients with cleft palate. In addition, nasalance values and the Nasality Severity Index (NSI) 2.0 were determined. The relationship between these speech outcomes and the scores on the VELO parent report was determined using Spearman rank-order correlation coefficients. ResultsModerate to strong correlations were found between the total score on the VELO parent report and five speech variables: the VPC-SUM score (rs = −0.476), speech understandability (rs = −0.657), passive CSC's (rs = −0.654), speech acceptability (rs = −0.591) and the need for C(L)P-related speech therapy (rs = −0.711). Furthermore, these variables were associated with at least one subscale of the VELO questionnaire. Discussion and conclusionCorrelations between speech outcomes and the Dutch version of the VELO questionnaire provide evidence for the construct validity of this version of the instrument. Furthermore, insights in these associations may lead the way to efficient therapy approaches, targeting speech features with the greatest impact on the patient's health-related quality of life.

Health-related quality of life in patients with cleft palate: Reproducibility, responsiveness and construct validity of the Dutch version of the VELO questionnaire

ObjectivesRecently, the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) questionnaire, which evaluates the impact of speech and swallowing difficulties on health-related quality of life (HRQoL) in patients with VPI (Skirko et al., 2012), was translated to Dutch (Bruneel et al., 2017). The purpose of this study was to evaluate the reproducibility, responsiveness and construct validity of this Dutch version of the questionnaire. MethodsTo evaluate the reproducibility, 50 parents and 14 children with cleft palate re-completed the questionnaire after two weeks. Thirty-five parents and 8 children with cleft palate completed the VELO questionnaire after one year for the evaluation of the responsiveness. The correlation between age and the VELO questionnaire (construct validity), and the internal consistency (Cronbach's α) were re-determined based on the responses of 73 parents and 24 children. ResultsBased on descriptive statistics, results of the Wilcoxon signed rank-test, and the absolute (SEM) and relative (ICC) consistency, the questionnaire showed good reproducibility. VELO scores did not significantly differ after one year, neither when performing separate analyses for the intervention (speech therapy) and the non-intervention group. Correlations indicated higher HRQoL, as perceived by the parents, with increasing age. The reverse was the case for the youth report. Cronbach's α showed excellent internal consistency for both reports. ConclusionsThe VELO questionnaire showed good reproducibility and internal consistency. Moreover, results reconfirmed the age effect on VELO scores. To understand the implications of the results regarding the questionnaire's responsiveness, future research should focus on the identification of factors influencing the patient's evolution in HRQoL.

Validation of the Chinese Velopharyngeal Insufficiency Effects on Life Outcomes Instrument.

To translate the Velopharyngeal Insufficiency Effects on Life Outcomes (VELO) instrument into Chinese and test its psychometric properties. Quality of life instrument translation and validation. The original English version of the VELO instrument was translated into Mandarin, back-translated, and adapted among the Chinese population, based on the standardized guidelines for the cross-culture adaption process. Velopharyngeal insufficiency (VPI) patients were identified by a professional speech and language pathologist. Internal reliability of the VELO instrument was assessed by the Cronbach's α coefficient. Discriminant validity was tested by the Mann-Whitney U test. Construct validity was assessed by factor analysis. A total of 113 patients with VPI and 72 parents of the patients were enrolled. The mean age of the VPI patients was 14.8 years. Internal reliability was excellent; Cronbach's α coefficients were 0.92 and 0.94 for VPI patients and their parents, respectively. The Chinese VELO discriminated well between the VPI group and the controls, with a mean (standard deviation) score that was significantly lower for the VPI group (74.8 [25.7]) than the control group (98.0 [15.9]) (P < .001). The total scores and scores in the emotional domain or perception domain showed differences between VPI patients and their parents. Similar to the original study, the factor loading after rotation followed hypothesized domains largely, in spite of items from several domains loaded on the same factor. The translated Chinese version of the VELO instrument demonstrated an acceptable reliability, discriminant validity, and construct validity. These psychometric properties suggested theoretical evidence for the further use of the VELO instrument among Chinese patients with VPI. 3b Laryngoscope, 129:E395-E401, 2019.

Spanish Linguistic Validation of the Velopharyngeal Insufficiency Effects on Life Outcomes: VELO-Spanish.

Background:Quality of life (QOL) assessments are useful tools that measure a patient’s health status and monitor patient-reported outcome measures. This study highlights the process of linguistic validation of a QOL assessment to serve Spanish-speaking families and ultimately help decrease language barriers in the treatment of velopharyngeal insufficiency (VPI).Methods:The standardized linguistic validation process included forward and backward translation, reconciliation, and cognitive interviews with patients and families. Preliminary instrument test-retest measurement was assessed. Eligibility for cognitive interviews included families with familiarity of velopharyngeal insufficiency. Exclusion criteria included illiteracy and parent and child respondents who do not speak Spanish. Reliability was tested by intraclass correlation (ICC) on VPI Effects on Life Outcomes (VELO)–Spanish instruments completion on 2 measurements from the medical record.Results:The instrument was optimized through a standardized forward and backward translation process. Further problematic language was identified during cognitive interviews with families and their children. In the second interview, only minimal changes were needed. Twenty-one patients (8 males and 13 females) were included. Mean (SD) age was 8.0 (5.3) years (range, 3–21 years). The mean (SD) Velo-Spanish score was 65 (22.1); range 32.7–100. The VELO-Spanish instrument demonstrated excellent test–retest reliability [ICC = 0.91; n = 21 and internal consistency (α = 0.96)].Conclusions:The Spanish VELO has been developed and refined for use in Spanish-speaking populations as a VPI-specific QOL instrument. The linguistic validation process including cognitive interviews and initial reliability testing. The instrument may improve the understanding of patient-reported outcomes and potential disparities from linguistic and cultural barriers in VPI treatment

Health-related quality of life in patients with cleft palate: Validity and reliability of the VPI Effects on Life Outcomes (VELO) questionnaire translated to Dutch

BackgroundDisease-specific health-related quality of life (HRQOL) questionnaires provide the clinician with important information regarding the impact of the disease on functioning and well-being. For patients with velopharyngeal insufficiency (VPI), the VPI Effects on Life Outcomes (VELO) questionnaire was developed and validated in English by Skirko et al. (2012). However, a valid and reliable Dutch translation of this questionnaire is not available yet. MethodsThe English questionnaire was translated to Dutch following a forward-backward translation procedure. A linguistic validation and the evaluation of the internal consistency (Cronbach's α) of this Dutch version were performed based on the responses of 39 parents of patients with cleft (lip and) palate (mean age: 6.8 years) (parent report) and the responses of 14 patients older than 8 years (mean age: 9.5 years) (child report). Additionally, the concurrent validity was assessed by comparing the scores on the parent report to those on the pediatric voice handicap index. Furthermore, the validity of the parent proxy assessment and the relationship between age and responses on the VELO questionnaire were investigated. Based on the responses of an age and gender matched control group without cleft palate, the discriminant validity was evaluated. ResultsThe parent report was easy to complete for all parents. Nine of the fourteen (64%) patients were able to complete the child report independently. The median scores on the parent report and the child report were 82.7 and 95.1 respectively. The patient group had a significantly worse perception of HRQOL compared to the control group (p < 0.001; p = 0.029). There were no significant differences between the responses of the parent and their child's (p = 0.345). A significant positive correlation was found between the score on the parent report and the age of the patients (p = 0.001). Furthermore, a significant negative correlation was found between the parent report and the P-VHI (p < 0.001). Cronbach's α was 0.955 and 0.817 for the parent report and the child report respectively. ConclusionThe Dutch VELO questionnaire is a valid, reliable and user-friendly tool that provides important information about HRQOL in patients with cleft (lip and) palate.

Change in Quality of Life with Velopharyngeal Insufficiency Surgery.

(1) To define the minimal clinically important difference (MCID) of the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument, and (2) to test for the change in quality of life (QOL) after VPI surgery. Prospective observational cohort. VPI clinic at a tertiary pediatric medical center. Children with VPI and their parents completed the VELO instrument (higher score is better QOL) at enrollment and then underwent VPI surgery (Furlow palatoplasty or sphincter pharyngoplasty, n = 32), other treatments (obturator or oronasal fistula repair, n = 7), or no treatment (n = 18). They completed the VELO instrument again and an instrument of global rating of change in QOL at 1 year. The MCID was anchored to the global change instrument scores corresponding to "a little" or "somewhat" better. Within-group (paired t test) and between-group (Student t test) changes in VELO scores were tested for the VPI surgery and no treatment groups. The association between treatment group and change in VELO scores was tested with multivariate linear regression, adjusting for confounders. Follow-up was obtained for 37 of 57 (65%) patients. The mean (±standard deviation) change in VELO scores corresponding to the MCID anchor was 15 ± 13. The VELO score improved significantly more in the VPI surgery group (change, 22 ± 15; P < .001) than in the no treatment group (change, 9 ± 12; P = .04), after adjusting for confounders (P = .007 between groups). VPI surgery using the Furlow palatoplasty or sphincter pharyngoplasty improves VPI-specific QOL, and the improvement is clinically important.

Validated patient-reported outcome instruments for velopharyngeal insufficiency.

Velopharyngeal insufficiency (VPI) affects speech, swallowing, and many psychosocial aspects of life in a way best measured by quality-of-life (QOL) instruments. QOL instruments are patient-reported outcome instruments that provide a method of measuring the value that patients place on their health-related experiences. These instruments allow us to quantify patients' QOL during assessment as well as the clinical improvement that we seek with treatment. Two instruments have primarily been used in the VPI population: the Pediatric Voice Outcomes Survey (PVOS) and the VPI Effects on Life Outcomes (VELO) survey. Each has undergone a different level of assessment. The first step in using an instrument involves understanding how it functions. The PVOS was modified from an adult voice-specific functional status instrument. It was tested for reliability and validated against other patient-reported instruments and has been used to measure change in voice function with VPI surgery. The VELO was developed with comprehensive VPI-specific content and validated against several other measures important in VPI. It was found to be reliable and responsive to change in QOL. The VELO has several subscales (Speech Problems, Swallowing Problems, Situational Difficulty, Perception by Others, Emotional Impact, and Caregiver Impact) that can be used to understand the subtleties of QOL in patients with VPI. Comparison of the effect sizes shows that the VELO has a larger effect size (1.1) than the PVOS (0.6) and may be more capable of detecting change in QOL with treatment. These instruments can be useful for patient assessment, providing a framework for discussion and providing data for research.

Validity and Responsiveness of VELO: A Velopharyngeal Insufficiency Quality of Life Measure

Test the Velopharyngeal Insufficiency (VPI) Effects on Life Outcomes (VELO) instrument for validity, reliability, and responsiveness. Observational cohort. Academic tertiary medical center. Children with VPI (n = 59) and their parents (n = 84) were prospectively enrolled from a pediatric VPI clinic. Pediatric speech language pathologists diagnosed VPI using perceptual speech analysis and rated VPI severity and speech intelligibility deficit (each as minimal, mild, moderate, or severe). All parents and youth 8+ years old (n = 24) completed the VELO instrument and other quality-of-life questionnaires at baseline; the first 40 subjects completed the VELO instrument again 2 weeks later. Treatments included Furlow palatoplasty (n = 20), sphincter pharyngoplasty (n = 14), or an obturator (n = 2), and 29 of 36 (81%) subjects completed the questionnaires 3 months posttreatment. VELO was tested with correlations for criterion validity against VPI severity, construct validity against speech intelligibility and velopharyngeal gap size, and concurrent validity against other quality-of-life measures (r > .40 demonstrating validity); for test-retest reliability using intraclass correlation (>.6 demonstrating reliability); and for responsiveness with the 3-month posttreatment measure using the paired t test. Parental responses are reported; youth responses showed similar results. The VELO instrument did not meet criterion validity (r = -.18, P = .10), or functional construct validity (r = -.37, P = .001), but did meet anatomic construct and concurrent validity (each r > .50, P < .01). VELO scores demonstrated excellent test-retest reliability (r = .85, P < .001) and responsiveness (baseline 54 ± 14 to posttreatment 70 ± 18, P < .001). VELO provides a VPI-specific quality-of-life instrument that demonstrates concurrent validity, test-retest reliability, and responsiveness to change in quality of life with treatment.

Validity and Responsiveness of VELO: A VPI QoL Instrument

Objective: In a study of patients with velopharyngeal insufficiency (VPI) diagnosed by pediatric speech pathologists, test the VPI Effects on Life Outcomes (VELO) instrument for criterion validity, construct validity, reliability, and responsiveness (ability to detect change in quality of life). Method: VPI subjects/parents completed the VELO at baseline, 2 weeks later, and 3 months posttreatment. Criterion-validity tested correlation between VELO score and VPI severity; construct-validity tested correlation with speech intelligibility. Test-retest reliability tested intraclass-correlation between baseline VELO score and 2-week score. Responsiveness tested mean baseline and posttreatment scores with the paired t test. Results: Parental responses are reported (n = 83); youth responses (obtained in 8+ year-olds only; n = 24) showed similar results. VPI severity (minimal n = 11, mild n = 31, moderate n = 27, severe n = 14) and speech intelligibility were rated by pediatric speech pathologists. The VELO instrument did not meet criterion validity (Spearman r = −0.21, P = .07) but did meet construct validity (Spearman r = −0.36, P = .001). VELO scores demonstrated excellent test-retest reliability ( r = 0.85, P &lt; .001, n = 40). Treatments included Furlow palatoplasty (n = 20), sphincter pharyngoplasty (n = 14), or an obturator (n = 2) with n = 28 (78%) completing the VELO posttreatment. The VELO showed responsiveness to treatment improving from baseline 54 ± 15 to posttreatment 70 ± 18 ( P &lt; .001). Conclusion: VELO provides a VPI specific quality of life instrument that demonstrates construct validity, test-retest reliability, and responsiveness to change in quality of life with treatment.
