Prospective study on health-related quality of life, oral mucositis and oral health on during treatment of head and neck cancer.

BACKGROUND: Few studies have examined health related Quality of Life (HR-QoL) during the treatment of head and neck cancer (HNC) with even fewer focusing on the impact of oral mucositis (OM) on HR-QoL. Studies performed during treatment of HNC makes it possible to follow fluctuations in HR-QoL, OM and other treatment related side effects. The aim was to prospectively analyze HR-QoL, changes in clinical variables and the impact of OM on HR-QoL during HNC treatment. MATERIALS AND METHODS: Patients were recruited before commencing curative cancer treatment and were given professional oral care weekly during oncologic treatment. HR-QoL was reported before, during (week 2, 4 and 6) and three months after treatment using the EORTC Quality of Life questionnaires C30 and H&N35 and the stimulated whole salivary secretion rate was determined at the same time-points. OM (erythema and ulceration) was registered using the Oral Mucositis Assessment Scale (OMAS), at baseline, weekly during treatment and post treatment. Differences in HR-QoL between different timepoints were analyzed. To analyze the impact of OM on HR-QoL the patients were categorized into two groups: no/mild OM (OMAS ulceration score 0-1) or severe OM (OMAS ulceration score ≥ 2) and HR-QoL was compared between the two OM groups at three timepoints during treatment. RESULTS: Fifty-seven patients (43 men, 14 women), with a mean age of 58 years were included. Patients reported progressively impaired HR-QoL, with peak issues noted at weeks 4 and 6, particularly in social eating, senses, appetite loss, sticky saliva, and decreasing salivary secretion rates were determined. Patients with severe OM reported worse HR-QoL compared to those with no/mild OM. Persistent problems 3 months post treatment were appetite loss, dry mouth, senses (smell and taste) and problems with social eating. CONCLUSION: Patients experienced exacerbated symptoms and problems weeks 4 and 6 of oncological treatment, especially among those with severe OM, stressing the importance of clinically monitoring the patients to reduce and alleviate their symptoms. Persistent problems three months post treatment are likely associated with the reduced salivary secretion rate indicating that patients should be monitored also after completed oncological treatment.

Salivary, lacrimal and nasal (SALANS) measure to assess side effects following radioactive iodine treatment: development, psychometric properties, and factor structure.

PURPOSE: This study aimed to develop and psychometrically evaluate a patient-reported outcome measure (PROM), SAlivary, LAcrimal, NaSal (SALANS), to document patients' symptoms after radioactive iodine (RAI) treatment for differentiated thyroid cancer (DTC). METHODS: We generated and iteratively revised SALANS items based on expert input, focus group discussions and feedback from cognitive testing (n = 17). We administered an initial SALANS measure with 39 items to patients diagnosed with DTC in the past two years (n = 105). Exploratory factor analysis (EFA) examined the factor structure of the SALANS items. We assessed the consistency reliability and related the total and subscale scores of the final SALANS to existing PROMs to assess validity. RESULTS: The final SALANS consisted of 33 items and six subscales (sialadenitis, taste, xerostomia, dry eyes, epiphora, and nasal) with six factors extracted by EFA. The six subscales demonstrated good internal reliability (α range = 0.87-0.92). The SALANS total score showed good convergent validity with the Xerostomia Inventory (r = 0.86) and good discriminant validity with a measure of spirituality (r = - 0.05). The mean SALANS total score was significantly higher (d = 0.5, p < 0.04) among patients who had RAI compared to those who did not have RAI. CONCLUSION: Preliminary evidence suggests that SALANS is a novel and reliable PROM to assess the type and frequency all symptoms experienced after RAI treatment for DTC. Future work is needed to further validate and develop the scale.

The evaluation of clinical factors affecting oral health impacts on the quality of life of Iranian elderly patients visiting dental clinics: A cross-sectional study.

BACKGROUND: Iran will soon have an aging population. Healthcare providers must consider factors affecting the quality of life for those 60 and older. Understanding oral health as one of these factors can improve the elderly's quality of life. Oral health-related quality of life (OHRQoL) is a crucial reflection of individuals' general well-being and their overall quality of life linked to health. This study aimed to evaluate the OHRQoL among elderly Iranians referring to Azad University of Medical Sciences in Tehran. METHODS: In this cross-sectional study, 171 individuals over 65 (93 men and 78 women) were evaluated using OHIP-14 and GOHAI-12 questionnaires to analyze their quality of life. Gender, age, systemic diseases, using medications and dentures, the number of remaining teeth, and oral lesions were recorded. Salivary flow and xerostomia were analyzed with the spitting method and xerostomia index questionnaire, respectively. Also, four main flavor solutions were used to evaluate the taste perception. Data were analyzed using PASS11 and p value < .05 was the significance level. RESULTS: Based on OHIP-14 and GOHAI-12, Iranian older people's quality of life can be affected by cardiovascular diseases, hypertension, xerostomia, and the number of remaining teeth (p < .05). The results also showed a significant correlation between the OHIP-14 and GOHAI-12 scores (p < .001). Both indexes revealed that the number of remaining teeth, xerostomia, salivary flow, and taste perception greatly influenced participants' quality of life. More remaining teeth, improved salivary flow, and better perception of sweetness and sourness were all linked to a higher quality of life, while increased xerostomia, reduced salivary flow, and bitter taste perception were linked to a decline in overall well-being. Cardiovascular diseases, hypertension, and medication use were also found to significantly impact quality of life. CONCLUSION: This study's results indicate that cardiovascular diseases, hypertension, dry mouth, and tooth loss can negatively impact the elderly's quality of life. So, improving both systemic and oral health is vital for enhancing life quality in this age group.

Self- reported oral health and oral health- related quality of life among patients with diabetes mellitus in a tertiary health facility.

BACKGROUND: Considering the inter-relationship between Diabetes Mellitus (DM) and oral tissues, assessment of oral health status in relation to glycemic control might be informative about the disease condition, which might be pivotal to appropriate management and ultimately improve life satisfaction. This study therefore aimed to assess the pattern of self-reported diabetes related oral conditions and oral health-related quality of life (OHRQoL) among patients with DM at the University College Hospital (UCH), Ibadan, Nigeria. MATERIALS AND METHODS: A cross- sectional study using an interviewer administered questionnaire was conducted among in- and out- patients being managed for DM by the Endocrinology unit of the hospital. Data collected included bio-data, medical history, self-reported oral conditions and dental service utilisation. The impact of oral health related quality of life was measured using OHIP-14. Oral examination was done to assess oral mucosal lesions and their oral hygiene status. Data was analysed using SPSS 21. RESULTS: Eighty-four patients with diabetes consisting 23 (27%) in-patients and 61 (63%) out-patients were enrolled. Males were 26(31%) and females 58(69%); their ages ranged from 22 to 88 years with a mean of 60.9 ± 12.8 years. Most (67%) of the participants had one or more self-reported oral complaints, dryness (20.4%) being the most common and bad breath (4.6%) as the least reported. Poor glycemic level was found to be higher among the in-patients (82%) with random blood glucose > 200 mg/dL during admission, compared to the out-patient participants (51%) who had fasting plasma glucose > 110 mg/dL. Their oral hygiene status was assessed using simplified oral hygiene index and documented as fair (65%), poor (25%) and good (10%). About two-thirds (61%) had ever visited a dentist, majorly due to toothache. Only the pain (21.9%) and physical disability (26.3%) components of OHIP-14 were mainly found to affect the participants' OHRQOL. CONCLUSIONS: This study found high rate of self- reported DM related oral conditions notably oral dryness, and periodontal diseases particularly as teeth mobility and spontaneous exfoliation. Nonetheless, most of the study participants had fair OHRQoL while its physical pain, functional limitation and psychological disability components were most reported.

Impact of xerostomia and the use of dental prosthesis on the quality of life of elderly: a cross-sectional study

Aim: To evaluate the impact of xerostomia, edentulism, use of dental prosthesis, and presence of chronic diseases on quality of life in relation to oral health in institutionalized elderly individuals. Methods: This is a cross-sectional study. A questionnaire was administered containing the following instruments: Oral Health Impact Profile (OHIP-14), which measures the quality of life related to oral health; the Summated Xerostomia Inventory questionnaire (SXI-PL) for evaluation of xerostomia, sociodemographic data, clinical description, and patient-reported factors was assessed (edentulism, use of dental prostheses, and chronic diseases). Results: Most elderly individuals did not have any teeth in their mouths and used dental prosthesis. The impact on quality of life, considering the mean of the OHIP-14 scores, was positive in 58.3% of the elderly. Those who used a dental prosthesis were three times more likely to have their oral health negatively impacted (OR=3.09; 95%CI =1.17 8.11), compared to those who did not use, and individuals with xerostomia were more likely to have their oral health negatively impacted (OR=1.57; 95%CI=1.25-1.98) compared to those without xerostomia. There was no difference in the quality of life of individuals with and without chronic diseases. Conclusions: The feeling of dry mouth and use of dental prostheses negatively impacted the quality of life in relation to oral health of the elderly

Gender-wise comparison of oral health quality of life and its relationship with oral health parameters among elderly from Wroclaw, south-west Poland.

BACKGROUND: In recent years, there has been an increase of aging population with longer life expectancy in females. This study aims to compare some oral health parameters and quality of life in the elderly. METHODS: The survey involved 500 urban residents (Wroclaw, Poland) aged 65 and older, of both gender. Socio-demografic data were assessed by self-reported questionnaire. Clinical examination included oral health assessment by the World Health Organization criteria with extension and oral dryness (Chalacombe scale). Quality of Life (QoL) was evaluated using Euro-Quality of Life, Oral Health Impact Profile-14 and Patient Health Questionnaire-9, which were validated for the Polish population. The relationship strength between psychometric scale scores and sociodemographic and clinical factors was determined by calculating Spearman's linear correlation coefficient values and regression coefficient values. RESULTS: There was no gender-wise differences in oral health parameters, except for a higher number of decayed teeth in males (DT 1.9±3.2 vs 1.2±2.4; p = 0.34). Oral dryness was diagnosed significantly more frequently in females then males (36.9% vs. 25.5%; p = 0.076). The males were significantly more likely to have high treatment needs (36.1% vs. 26.9%; p = 0.032) and they required urgent dental treatment (7.2% vs. 2.8%; p = 0.022). There were no significant differences in terms of QoL evaluated by EQ-5D, EQ-5D VAS or OHIP-14 questionnaires between males and females (0.832±0.194 vs 0.855±0.197, 67.9±10.9 vs 66.1±18.6, 7.2±12.9 vs 8.5±14.0, respectively; p > 0.05). However, females presented the higher severity of depressive symptoms measured by the PHQ-9 questionnaire (4.0±4.1 vs. 2.8±3.8; p<0.001). CONCLUSION: It can be concluded that the independent predictors which significantly affect the high QoL scores on the EQ-5D scale were found to be female gender, age below 75, high or middle income, independence in daily life, a low number of comorbidities, lack of oral treatment needs.

Oral health-related quality of life in oral cancer patients: systematic review and meta-analysis.

Aim: The purpose of this meta-analysis was to evaluate the impact of oral health on quality of life in oral cancer patients (OCPs). Methods: PubMed, Scopus and Web of Science databases were searched for publications on oral health-related quality of life (OHRQoL) in OCP and the information was extracted according to the PRISMA guidelines. A random effect model was used to obtain the pooled standard mean differences of Oral Health Impact Profile (OHIP)-14 questionnaire responses in meta-analysis. Results: total of 12 research papers were analyzed and revealed poor OHRQoL in OCPs (standard mean difference: 2.53; 95% CI: 1.55-3.50; p < 0.00001) compared with healthy individuals due to the effects of oncotherapy. Moreover, OHRQoL deteriorated with combinations of different treatment modalities. Conclusion: Oral health and oncotherapy can affect the quality of life in OCPs.

Perceived xerostomia, stress and periodontal status impact on elderly oral health-related quality of life: findings from a cross-sectional survey.

BACKGROUND: To investigate if self-perceived xerostomia and stress are significant variables on the Oral-Health Related Quality of Life (OHRQoL) of elderly patients, considering the periodontal status, oral hygiene habits and sociodemographic characteristics simultaneously. METHODS: The study cohort included 592 participants (320 females/272 Males), aged 65 years or older, representing the elder inhabitants of the Study of Periodontal Health in Almada-Seixal (SoPHiAS). Patients answered a socio-demographic and oral hygiene habits questionnaire. The Oral Health Impact Profile-14 (OHIP-14), Summated Xerostomia Inventory-5 (SXI-5) and Perceived Stress Scale-10 (PSS-10) were used. Full-mouth circumferential periodontal inspection was carried out. Multivariable regression analyses were used considering the level of periodontitis, clinical characteristics, the number of teeth, SXI, PSS-10, age, gender and oral hygiene habits. RESULTS: Self-perceived xerostomia and stress showed a positive significant correlation with OHRQoL and each of its domains. Multiple linear regression analysis demonstrated the significant impact of SXI-5 (B = 1.20, p <  0.001) and PSS-10 (B = 0.35, p <  0.001) on the OHRQoL. SXI-5 (Odds Ratio (OR) = 1.28, p <  0.001) and PSS-10 (OR = 1.03, p = 0.022) were associated with a more frequently affected OHRQoL. The number of missing teeth, being male, mean probing depth and mean clinical attachment loss were also significant towards a frequently affected OHRQoL. Conversely, age was negatively associated with a lower OHRQoL. CONCLUSION: Self-perceived xerostomia and stress are significant variables towards OHRQoL in elderly patients. Future studies should consider these self-perceived xerostomia and stress when investigating the impact of periodontitis and missing teeth on quality of life of older adults.

Effect of the sense of coherence and associated factors in the quality of life of head and neck cancer patients.

The sense of coherence (SOC) is a measure of global orientation regarding the ability of individuals to cope with stressful situations. The aim of the present study was to evaluate the association between SOC and quality of life (QoL) and clinical and sociodemographic characteristics among survivors of oral, oropharynx, hypopharynx, or larynx cancer. A cross-sectional study was conducted with 90 cancer patients in follow up at the Santa Maria University Hospital in southern Brazil who had completed conformal 3D radiotherapy at least three months earlier. QoL was assessed using the University of Washington Quality of Life (UW-QOL) questionnaire and SOC was measured using the Brazilian version of the SOC-13 questionnaire. Data on socio-demographic characteristics and the disease were obtained from patients' charts. Oral clinical conditions were also evaluated. Associations between exploratory variables and mean UW-QOL scores were evaluated through Poisson regression and the results were presented as rate ratios (RR) and 95% confidence intervals (CI). The mean overall UW-QOL score was 67.90 (± 18.71). Moderate and high SOC scores were associated with higher mean UW-QOL scores, that is, individuals with a stronger SOC demonstrated better QoL, (p < 0.05). Regarding the clinical variables, individuals with advanced stage cancer and those with hyposalivation and trismus had poorer QoL (p < 0.05). Patients with a greater SOC reported a better quality of life. Our findings show the importance of focusing on psychosocial factors, which can alleviate the impact caused by the disease and improve the QoL of these patients.

Xerostomia-related quality of life for patients with oropharyngeal carcinoma treated with proton therapy.

PURPOSE: We report longitudinal patient-reported quality-of-life (QoL) outcomes related to xerostomia in patients with oropharyngeal cancer treated with intensity-modulated proton therapy (IMPT). MATERIALS AND METHODS: Patients treated from May 2012 through December 2016 at a single institution for AJCC7 stage III-IV, M0 oropharyngeal cancer were given the 15-item Xerostomia-Related QoL Scale (XeQoLS) before, during, and for up to 2 years after treatment. We evaluated the evolution of xerostomia-related QoL over that time, and examined potential associations between those measures with clinical characteristics. RESULTS: Sixty-nine patients had XeQoLS scores at baseline and at least once either during or after treatment. The mean (±SD) XeQoLS score (0-4) was 0.24 ±â€¯0.57 at baseline. Subsequent scores were 2.00 ±â€¯1.01 at 6 weeks on treatment, and 1.03 ±â€¯0.76, 0.97 ±â€¯0.78, 0.82 ±â€¯0.69, and 0.70 ±â€¯0.75 at 10 weeks, 6 months, 1 year, and 2 years after treatment, respectively. All were statistically different from baseline (p < 0.001). Univariate analyses demonstrated associations between XeQoLS score and time (p < 0.0001 for each interval), baseline XeQoLS score (p < 0.0001), stage (p = 0.008), N status (p = 0.006), and mean oral cavity dose (p = 0.038), but not for age, sex, T status, receipt of chemotherapy, smoking history, disease site, laterality of neck irradiation, mean parotid dose, or mean submandibular dose. Multivariate analysis suggested that baseline XeQoLS scores, phase of treatment, and N status were associated with XeQoLS scores measured during treatment and recovery. CONCLUSIONS: Patients receiving IMPT reported the greatest xerostomia-related QoL impairment at 6 weeks on treatment, with a 49% improvement by 10 weeks after treatment; however, XeQoLS scores remained above baseline after 2 years. As we aim to establish the value of IMPT in oropharyngeal tumors to de-intensify treatment over conventional therapy, these data help inform discussions about xerostomia-related quality of life for patients with oropharyngeal cancer treated with IMPT.

Self-reported oral and general health related to xerostomia, hyposalivation, and quality of life among caries active younger adults.

Objective: The aim was to study prevalence of xerostomia, hyposalivation and quality of life among caries active younger adults.Materials and methods: A questionnaire regarding oral and general health, xerostomia and quality of life was mailed to 134 caries active (CA) and 40 caries inactive (CI) patients, 25-50 years of age (mean age 39.9 ± 6.2 years) treated at a Swedish Public Dental Service clinic, regarding oral and general health, xerostomia and quality of life. Caries data and unstimulated whole salivary flow rates were obtained from dental records.Results: The overall response rate was 69%. Dental records confirmed that CA patients had more decayed teeth over time than CI patients (p < .001). The CA group reported worse oral health (p < .001) and general health (p < .01), more xerostomia (p < .001) and lower salivary flow rate (p < .01) compared to CI patients. Xerostomia was inversely related to unstimulated whole salivary flow rates as well as to oral and general health (p < .01). There were no differences between groups in quality of life.Conclusion: Younger caries active adult patients reported significantly more xerostomia and hyposalivation compared to caries inactive patients. Xerostomia and hyposalivation were inversely related to perceptions of oral and general health, but not to quality of life.

Impact of xerostomia on the quality of life of patients submitted to head and neck radiotherapy

BACKGROUND: The aim of the present work was to evaluate the impact of xerostomia on the quality of life of patients who underwent radiotherapy in the head and neck region. MATERIAL AND METHODS: This was a cross-sectional, quantitative study. The sample comprised 40 patients whose xerostomia was classified through the xerostomia inventory and the quality of life evaluated through the oral health impact profile questionnaire (OHIP). RESULTS: The majority of participants were male (75%), mean age 58.7 years. According to the degree of severity of the xerostomia, the average score among the participants was 36 points, this being considered moderate xerostomia. A significant impact was observed, with the median score 11 points, with the highest scores in the domains related to functional limitation, physical pain and physical disability. The majority of the participants (97.5%) had reduced salivary flow after the end of radiotherapy. There was a significant positive correlation between the degree of xerostomia and reduced quality of life, Pearson correlation 0.5421, (p < 0.05). CONCLUSION: Based upon the results it is concluded that xerostomia has a negative impact on the quality of life of patients who undergo radiotherapy in the head and neck region

Oral Health-Related Quality of Life Among Publicly Insured Mental Health Service Outpatients With Serious Mental Illness.

OBJECTIVE: The study investigated factors associated with unmet need for dental care and oral health-related quality of life (OHQoL) among individuals with serious mental illness receiving outpatient care in a public mental health program serving a largely low-income population, mostly from racial-ethnic minority groups. METHODS: Cross-sectional interview data were collected from a convenience sample (N=150) of outpatients. Adjusted risk ratios (ARRs) and adjusted risk differences (ARDs) were estimated by logistic regression models to examine the independent contribution of sociodemographic and clinical factors to low OHQoL and past-year unmet dental need, defined as inability to obtain all needed dental care. RESULTS: More than half of participants reported low OHQoL (54%) and a past-year dental visit (61%). Over one-third (39%) had past-year unmet dental need. Financial barriers (ARR=3.16) and nonfinancial barriers (ARR=2.18) were associated with greater risk for past-year unmet dental need after control for age, gender, high dental anxiety, and limited English proficiency. ARDs for financial and nonfinancial barriers indicated absolute differences of 40 and 27 percentage points, respectively. Unmet dental need (ARR=1.31), xerostomia severity (ARR=1.20), and a schizophrenia spectrum diagnosis (ARR=1.33) were associated with low OHQoL, after control for age and current smoking, with ARDs ranging from 11 to 15 percentage points. CONCLUSIONS: Improving oral health promotion, oral health service access, and the integration of the mental and oral health systems may help reduce the high prevalence of low OHQoL in this population, given that low OHQoL is partly driven by unmet dental need.

Perceived Stress, Social Support, and Dry Mouth Among US Older Chinese Adults.

OBJECTIVES: Dry mouth is a common condition among older adults that negatively influences oral health, general health, and quality of life. The role of psychosocial factors in oral health conditions and diseases remains largely unknown. We conducted a study to examine the relationship between perceived stress and dry mouth among US older Chinese adults and further investigated the potential moderating role of social support and social strain from different sources in the relationship. DESIGN: Cross-sectional analysis. SETTING: Baseline of the Population Study of Chinese Elderly in Chicago, a community-engaged, population-based longitudinal study of health and well-being among community-dwelling US older Chinese adults. PARTICIPANTS: Individuals 60 years or older (N = 3157). MEASUREMENTS: Perceived stress was measured by the 10-item Chinese Perceived Stress Scale to evaluate the degree to which life situations were perceived as stressful during the preceding month on a 5-point scale, ranging from 0 ("never") to 4 ("very often"). Dry mouth was a binary self-reported outcome variable (1 = "dry mouth"). Social support was measured by the Health and Retirement Study's social support and strain scale from sources including spouse, other family members, and friends with a 3-point response set, ranging from 0 ("hardly ever") to 2 ("often"). Sociodemographics and disease processes were assessed as covariates. We conducted stepwise logistic regressions with interaction terms. RESULTS: Having higher levels of perceived stress was significantly associated with a higher likelihood of reporting dry mouth (odds ratio = 1.03; 95% confidence interval = 1.02-1.04). The effect of perceived stress on dry mouth may vary by levels of family and friend support. CONCLUSION: Perceived stress may influence dry mouth either directly or indirectly. To prevent or reduce dry mouth, in addition to disease processes, interventions need to consider psychosocial factors in dry mouth, especially perceived stress and social support, in this growing population.

Association between decrease in frequency of going out and oral function in older adults living in major urban areas.

AIM: To examine the association between a decrease in the frequency of going out and oral function in independent older adults living in the urban area of Tokyo. METHODS: The participants analyzed were 785 older adults from the "Takashimadaira Study" (344 men and 441 women, age 77.0 ± 4.6 years). This study investigated the following items: decrease in frequency of going out; basic characteristics (sex, age); physical factors, such as oral function (difficulty chewing, difficulty swallowing, dry mouth); body pain; the Japan Science and Technology Agency Index of Competence; physical activities; psychological factors, such as the Geriatric Depression Scale-15 score; and social and environmental factors, such as the presence or absence of participation in organization activities. RESULTS: To investigate the factors associated with a decrease in frequency of going out, logistic regression analysis showed an association with age (OR 1.08, 95% CI 1.03-1.13), difficulty chewing (OR 2.41, 95% CI 1.52-3.83), dry mouth (OR 1.68, 95% CI 1.07-2.64), body pain (OR 1.78, 95% CI 1.14-2.78), Japan Science and Technology Agency Index of Competence scores (OR 0.91, 95% CI 0.84-0.99), physical activities (OR 0.99, 95% CI 0.98-1.00), Geriatric Depression Scale-15 scores (OR 1.13, 95% CI 1.05-1.21) and organization activities (OR 1.94, 95% CI 1.22-3.07). Covariance structural analyses showed that both "difficulty chewing" and "dry mouth" significantly affected "decrease in frequency of going out." In addition, decrease in frequency of going out was significantly affected by " Geriatric Depression Scale-15 scores" through oral function. CONCLUSIONS: The relationship between oral function and decrease in frequency of going out was clarified, after the multifaceted factors were adjusted. Geriatr Gerontol Int 2019; 19: 792-797.

Validating the Xerostomia Inventory in a radiation-induced xerostomia population in German language.

OBJECTIVES: Though xerostomia is a frequent oral symptom, there is no validated disease-specific questionnaire in German. The purpose of this study was to translate and validate versions of the Xerostomia Inventory and the Summated Xerostomia Inventory in a German-speaking population. PARTICIPANTS AND METHODS: Thirty-nine patients including 18 patients suffering from radiation-induced xerostomia enrolled in this study. Both questionnaires were translated into German language according to international accepted guidelines. For validation, we evaluated reliability, validity, and responsiveness using the COSMIN manual for cross-cultural adaptation. RESULTS: Cronbach's α was 0.92 for XI and 0.91 for SXI, showing both high internal consistency. Patients suffering from xerostomia showed significantly higher average scores demonstrating its discriminant validity. Confirmatory factor analysis showed excellent "goodness-of-fit" values for SXI and good to moderate values for XI, confirming the assumed factor structures. The Xerostomia Inventory and its summated version both showed excellent test-retest reliability in the non-xerostomia group (ICC = 0.85 and 0.84). CONCLUSIONS: The XI and SXI in their cross-cultural adapted versions are the first validated self-report assessments for xerostomia in German language. They are characterized by practical design and can be easily interpreted by the treating physician.

Personality, xerostomia and OHRQoL among 35-54-year-olds.

OBJECTIVE: Personality characteristics mean that people may interpret similar symptoms differently, complicating the measurement of self-reported oral health, and so we tested the hypothesis that controlling for aspects of personality makes a difference to the association between xerostomia and oral-health-related quality of life. MATERIAL AND METHODS: A cross-sectional study was conducted of a representative adult population sample in Dunedin (New Zealand). Data were collected on xerostomia, OHRQoL and personality characteristics, using (respectively) the 5-item Shortened Xerostomia Inventory (SXI), the OHIP-14 and the Positive and Negative Affect Schedule (PANAS). Negative binomial regression was used to model the association between the SXI and the OHIP-14 scores, and models with and without the PANAS score were compared. RESULTS: The participation rate was 51.3%, with complete OHIP-14 data available for 250 individuals (56.5% female). The SXI score (mean 6.9, sd 1.8) was strongly and positively associated with the OHIP-14 score (in both models), as was the PANAS negative affect score in the second model, which also explained slightly more of the observed variance than the first model. However, the difference in model deviance fell short of the amount required to reject the hypothesis that adding the PANAS variables to the model made a significant difference. CONCLUSIONS: Considering aspects of personality in investigating OHRQoL remains a theoretically important undertaking, but adjusting for it in analyses of associations between xerostomia and OHRQoL is unlikely to be necessary.
