Translation and validation of the Hindi version of the Geriatric Oral Health Assessment Index

doi: 10.1111/j.1741‐2358.2011.00609.x Translation and validation of the Hindi version of the Geriatric Oral Health Assessment Index Purpose: To translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into Hindi and assess its validity and reliability for use among people in India. Materials and Method: After translation into Hindi, a total of 385 participants aged 55+ demonstrated acceptable validity and reliability when used for people in India. Individual GOHAI items were recorded and summed as originally recommended. The questionnaire sought information about socio‐demographic characteristics and self‐reported perception of general and oral health. Clinical examination included assessment of periodontal status and number of decayed teeth, missing teeth, filled teeth and crowned teeth. Result: Mean GOHAI score was 40.9 (SD, 10.6; range, 12–60). Cronbach’s alpha for the GOHAI score was 0.88, indicating a high degree of internal consistency and homogeneity between the GOHAI items. The test–retest correlation coefficient for add‐GOHAI scores was 0.72, indicating good stability. Add‐GOHAI scores increased with poorer perceived general and oral health. Convergent validity, construct validity and discriminant validity of the GOHAI were demonstrated. Conclusion: It could therefore be used as a valuable instrument for measuring oral health–related quality of life for people in this region.

Gerodontology 2011; doi: 10.1111/j.1741‐2358.2009.00360.x
Factors associated with the oral health‐related quality of life in elderly persons in dental clinic: validation of a Mandarin Chinese version of GOHAI Objectives: To translate the original English version of Geriatric Oral Health Assessment Index (GOHAI) into Mandarin Chinese and assess its reliability and validity for use among the elderly in inland China and to explore the factors associated with oral health‐related quality of life (OHRQoL). Methods: The original English version of GOHAI was translated, back‐translated and cross‐culturally adapted. The psychometric properties of GOHAI‐M were assessed in a sample of 263 people aged 60 years and over and OHRQoL was examined in 221 subjects using GOHAI‐M. Multiple regression analysis was conducted. Results: Internal consistency of the GOHAI‐M was excellent (Cronbach’s α : 0.81). Split‐half reliability coefficient was 0.80, and item‐scale correlation coefficient ranged from 0.25 to 0.71. Self‐rated oral health was significantly associated with OHRQoL (r_s = 0.505, p < 0.01). The relation coefficient between GOHAI‐M and self‐perceived need for dental treatment and number of missing teeth were 0.231 and ?0.653, respectively (p < 0.05). Multiple regression analysis found that better OHRQoL was significantly associated with better self‐ratings of oral health (β = 0.497, p = 0.01), number of missing teeth (β = 0.187, p < 0.01) and life satisfaction (β = 0.132, p < 0.05). Conclusion: The Mandarin Chinese version of GOHAI demonstrates acceptable reliability and validity. OHRQoL is associated with self‐rated oral health, number of missing teeth and satisfaction with life.     

Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects

doi: 10.1111/j.1741‐2358.2011.00606.x Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects Objective: To evaluate the reliability and validity of the Japanese version of the Oral Health Impact Profile for edentulous (OHIP‐EDENT‐J) patients. Background: Oral Health Impact Profile for edentulous is an appropriate instrument for assessing the Quality of life (QOL) in edentulous patients. However, the reliability and validity of the Japanese version had not been evaluated. Methods: The study was conducted on 116 edentulous patients (Group A, requiring new dentures, n = 61; Group B, already having dentures, n = 55). Cronbach’s alpha (α) was used to measure internal consistency of the summary scores for OHIP‐EDENT‐J and various subscales in Groups A and B. The interclass correlation coefficient (ICC) and 95% confidence interval of the summary scores for OHIP‐EDENT‐J and subscales were calculated. The summary scores for OHIP‐EDENT‐J in Groups A and B were compared with evaluate content validity. The Spearman’s correlation coefficient between the summary scores for OHIP‐EDENT‐J and the satisfaction with dentures (100 mm VAS) was calculated for Groups A and B to evaluate concurrent validity. Results: The reliability of the summary scores for OHIP‐EDENT‐J was good (α = 0.93). The ICC of the summary scores for OHIP‐EDENT‐J was 0.85. Summary scores for OHIP‐EDENT‐J were significantly different (p = 0.027) between Group A and Group B, with Group A having the higher value. The Spearman’s correlation coefficient for the degree of satisfaction with dentures and the summary scores for OHIP‐EDENT‐J, calculated for Groups A and B (n = 107), was ?0.609. Conclusion: The OHIP‐EDENT‐J, a questionnaire on oral health–related QOL comprising 19 items, showed good reliability and validity for edentulous patients.     

Validity and reliability of the Oral Impacts on Daily Performance (OIDP) scale in the elderly population of Bosnia and Herzegovina

doi: 10.1111/j.1741‐2358.2011.00584.x Validity and reliability of the Oral Impacts on Daily Performance (OIDP) scale in the elderly population of Bosnia and Herzegovina Objectives: To adapt the Oral Impacts on Daily Performance (OIDP) index for elderly people in Bosnia and Herzegovina and test its validity, reliability and responsiveness to change. Background: Clinical measures alone may not be adequate for assessing the oral health of individuals. Subjective oral health indicators tested within a particular cultural context may not be relevant across cultures. Materials and methods: The study population comprised 231 free‐living adults aged 65 years or older. The OIDP was cross‐culturally adapted from English into the Serbian language and its psychometric properties were tested. Data were collected using a clinical examination and a questionnaire containing the OIDP. Results: In terms of reliability, Cronbach’s alpha coefficient was 0.82 and the intraclass correlation coefficient 0.88. The very high correlation of OIDP with self‐rated oral health (r = 0.78) verified criterion validity, while construct validity was demonstrated through its significant and graded associations with other subjective health measures. OIDP change scores on a treated subsample showed moderate effect size (0.59) and were associated with perceptions of oral health change, providing evidence for its responsiveness to change. Conclusion: The Bosnian version of the OIDP showed satisfactory validity, reliability and responsiveness to change confirming its appropriateness for use among older populations in Bosnia and Herzegovina.     

Application of short-form oral health impact profile on elderly Japanese

Objectives: The purpose of this study was to use the oral health impact profile (OHIP‐14) to evaluate the impact of oral disease on the quality of life of a group of independently‐living elderly persons in an urban area of Japan. Subjects: A total of 1244 participants of the Senior Citizen's College, who attended the lectures once a week. They were community‐dwelling, independently‐living people over 60 years of age. Measurements: Japanese version of the short‐form OHIP‐14. Results: Internal reliability for the 14 items overall was very high (Cronbach's α = 0.95). Report of ‘painful aching’ and ‘uncomfortable to eat’ were the two most highly scored items using the mean sum OHIP‐14 score. A multiple logistic regression analysis indicated that the sum OHIP‐14 score had significant associations with self‐assessment of general health, dental status, and a perceived need for dental treatment. However, age, gender, dissatisfaction with financial status or education level was not significantly associated with the sum OHIP‐14. Compared with that of other countries, the items were ranked similarly, whereas the perceived magnitudes of the problems were quite different from other population. Conclusions: The OHIP‐14 in Japanese had a high internal reliability, was significantly associated with dental status and comparable ranking for items when compared with studies from other countries.     

Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City,India

doi: 10.1111/j.1741‐2358.2012.00651.x Oral health‐related quality of life and nutritional status of institutionalized elderly population aged 60 years and above in Mysore City, India Objective: To assess whether oral health–related quality of life (OHRQoL) is associated with nutritional status in the institutionalised elderly population of Mysore. Background: Malnutrition in the elderly has an evident impact on their general health and quality of life. Analysis of data of the Geriatric Oral Health Assessment Index (GOHAI) and their association with the Mini Nutritional Assessment (MNA) results improves our understanding of the complex relationship between oral health and malnutrition. Materials and methods: The study was conducted among the institutionalised elderly population in Mysore city, Karnataka. Data on socio‐demographic, oral health status were gathered. OHRQoL was evaluated using GOHAI, and malnutrition risk using MNA. Results: Out of 141 elderly, 41.1% were men and 58.9% were women with mean age of 72.2 ± 7.5 years. Mean GOHAI score was 47.03 ± 9.2, with 69.5% had low perception of oral health. Mean MNA score was 9.91 ± 2.4, 15.6% were malnourished, 52.5% were at risk of malnutrition and 31.9% were adequately nourished. A strong association was found between the mean GOHAI and MNA scores. Conclusion: Oral health–related quality of life was associated with nutritional deficit, and it requires a greater integration between dentistry and nutrition in the health promotion of older adults.     

TMD and GOHAI indices of Brazilian institutionalised and community-dwelling elderly

Rationale and objectives: Considering the controversy in the literature regarding several aspects of temporomandibular dysfunction (TMD) in elderly populations and the absence of reliable data on elderly Brazilians in this field, this study consisted of an evaluation of TMD prevalence and the self‐perception of oral health among institutionalised and community‐dwelling elderly in São José dos Campos, Brazil. Methods: Two hundred and fifteen community‐dwelling and 185 institutionalised elderly people were evaluated by the Helkimo anamnestic (Ai) and clinical dysfunction (Di) indices and answered a questionnaire using the Geriatric Oral Health Assessment Index (GOHAI). Results: The major prevalence of TMD symptoms was for the Ai0 (symptom‐free) group (69.5%), while the major prevalence of clinical signs was for the DiI (mild) group (56%). Women presented a higher AiII classification than men (χ² test, p = 0.049). Community‐dwelling elderly presented a significantly lower Ai0 classification than the institutionalised ones (Two ratios equality test, p < 0.001). There was no relationship between the institutionalised status and the clinical dysfunction index for Di0 and DiIII classification (Two ratios equality test, p = 0.194 and 0.535 respectively). The institutionalised elderly presented greater (One‐way anova = 0.005) self‐perception of oral health (33.45) than did the community‐dwelling group (32.66). There were only weak Pearson’s correlations among the anamnestic (?33.0%) or clinical (?14.7%) findings by the TMD and GOHAI indices. Symptom‐free (Ai0) institutionalised elderly presented better scores in all GOHAI dimensions and elderly representing an absence of clinical TMD signs (Di0) presented higher GOHAI physical dimension scores in both groups. Conclusions: The prevalence of TMD symptoms among this sample of elderly individuals was relatively low, self‐perception of oral health was reasonable and a weak, inverse correlation was found between TMD signs and symptoms and elderly self‐perception of oral health measured by the GOHAI index.     

Impact of new prostheses on the oral health related quality of life of edentulous patients

Objective: A study was conducted to evaluate the impact of the placement of complete dentures by using the Global Oral Health Assessment Index (GOHAI). Background: Oral health quality of life indicators can be used to evaluate the effects of dental treatments. Material and methods: The 26 participants were treated in a French University Clinic during 2002. They were randomly divided into two groups. Each group received new prostheses, but evaluation of the quality of life was made at different periods [baseline, denture placement (group 1), 6 and 12 weeks (group 2) after placement]. A questionnaire was used to collect information on patient's satisfaction with the previous and new prostheses. Nonparametric tests were used to test the relationships between patients’ satisfaction or baseline data and GOHAI variations with time as well as to compare mean values of GOHAI within each group. Results: At baseline, the impact of oral health problems was apparent; the mean GOHAI‐Add score was 45.8 (10.2). Six weeks after placement of the new denture, there was no difference in GOHAI scores compared with the initial assessment. An improvement in GOHAI score was observed 12 weeks after the participants received their new dentures (p < 0.05). Change in GOHAI‐Add scores was negatively correlated with the initial GOHAI‐Add score. Patients who preferred the new prosthesis enjoyed a positive change in GOHAI scores (p < 0.001). There was a relationship between participants’ satisfaction with the new dentures and change in GOHAI scores (p < 0.05). Conclusion: The GOHAI can be used to evaluate needs for and effect of the making of new complete dentures.

doi: 10.1111/j.1741‐2358.2012.00613.x
Derivation of the short form of the Oral Health Impact Profile in Spanish (OHIP‐EE‐14) Background and Objective: The Oral Health Impact Profile is the most frequently used and validated of the Oral Health Quality of Life instruments. Several short versions have been developed; and a validation of the OHIP‐49 in Spanish has been published. The objective was to develop the short version of the Oral Health Impact Profile in Spanish (OHIP‐EE‐14). Methods: Cross‐sectional study. One hundred and thirty‐one persons aged ≥60 years attending a social centre for the elderly, residents of a nursing home and persons seeking dental care at a dental school in Mexico City were interviewed and examined. The validity of each of the 49 questions was evaluated, and, to construct the short version, 14 items were selected. The perceived need for dental treatment, number of teeth, presence of coronal caries, root caries, presence of dental plaque and utilisation of removable prosthesis were measured. Internal consistency, repeatability and discriminant validity were calculated. Results: The OHIP‐EE‐14 was reliable (Cronbach’s‐α = 0.918, ICC = 0.825). Significant associations were found between OHIP‐EE‐14 and the number of teeth and perceived need for dental treatment. Conclusions: The OHIP‐EE‐14 is a reliable and valid instrument and can be used in subjects aged 60 years and over from Mexico City.     

Ontwikkeling van de Gedragsobservatieschaal Psychomotorische therapie voor demente ouderen (GPMT-dem).

PDevelopment of the Behaviour observation scale for Psychomotor Therapy for elderly people with dementia (BPMT-dem).Reliability and concurrent validity This article describes the development of the Behaviour observation scale for Psychomotor Therapy for elderly people with dementia (BPMT-dem). This scale was developed in the late 1980s in order to evaluate the effect of psychomotor group therapy on the cognitive, social, and emotional functioning of elderly people with dementia within the therapy situation. The currently described research investigates inter-assessor reliability and internal consistency of the ten subscales (such as memory, orientation, contact with others, initiative, anxious behaviour, aggressive behaviour) and three domains, as well as the scale’s correlation with other observation scales (concurrent validity) in two different patient groups. The first group consisted of clients receiving psychomotor therapy in a nursing home or a psychiatric hospital (N = 130). Inter-assessor reliability (Cohen’s kappa) varied between 0.27 and 1.00, the internal consistency of the subscales (Cronbach’s alpha) was calculated between 0.46 and 0.86, and that of the domains between 0.76 and 0.81. Based on the findings of this study 15 of the original 88 items were removed, 5 items were moved to other subscales and the text of 2 items was changed. Next, the subscale internal consistency and concurrent validity of this modified (73-item version) BPMT-dem was investigated in a group of 41 elderly participating in a support programme in meeting centres for elderly people with dementia and their caregivers. Cronbach’s alpha for the subscales in this study was calculated between 0.47 and 0.86. To determine concurrent validity, the BPMT-dem was compared with (subscales of) the Assessment Scale for Elderly Patients (ASEP), Behavioural assessment for Intramural Psychogeriatrics (BIP), Brief Cognitive Rating Scale (BCRS) and the Cornell Scale for Depression in Dementia. Correlations with related BPMT-dem subscales varied between 0.38 and 0.75. The inter-assessor reliability and concurrent validity of the 73-item version of the BPMT-dem are satisfactory. The internal consistency of 6 subscales is sufficient, and recommendations are proposed to improve the consistency of the remaining subscales. Further research to test the unidimensionality and scalability of the subscales of the BPMT-dem, as well as the effect of the recommended reformulation and removal of items, is recommended. Before the instrument can be used in actual practice, the psychometric qualities of the BPMT-dem73 need to be studied in a larger and in terms of severity of dementia more heterogeneous study sample, so that statements can also be made on which norms to use in various subgroups of elderly with dementia.

Relationships between Geriatric Oral Health Assessment Index scores and general physical status in community-dwelling older adults

doi: 10.1111/j.1741‐2358.2011.00597.x Relationships between Geriatric Oral Health Assessment Index scores and general physical status in community‐dwelling older adults Objective: The aim of this study was to investigate the relationships between Geriatric Oral Health Assessment Index (GOHAI) and general physical status among community‐dwelling older adults. Background: Geriatric Oral Health Assessment Index is a patient‐centred assessment of oral health for older adults. We hypothesised that GOHAI is a significant indicator of general physical status of older adults. Methods: This study included 354 adults (age, ≥65 years) living independently. Body mass index, handgrip strength and one‐leg standing time with eyes open were used to evaluate the general physical status. Spearman’s rank correlation coefficients were calculated to examine the relationships between the GOHAI scores, its three subdivided categories (physical function, psychological function and pain and discomfort) and each physical status measurement. A stepwise linear regression model was applied with each physical status measurement as the dependent variable and the GOHAI scores and its subdivisions as the principal independent variable. Results: Positive correlations were found between the GOHAI scores, its three subdivided categories and handgrip strength. The physical function category positively correlated with one‐leg standing time. The GOHAI and the pain and discomfort category scores were retained in the final models of stepwise regression for handgrip strength, and significant relationships persisted after adjustments for demographic, psychosocial, medical and dental status. Conclusion: The GOHAI scores and its pain and discomfort category score may be significant indicators of body muscle strength.     

Oral health‐related quality of life of older people from three South American cities

Objective: To describe subjective oral health status and its association with overall health conditions and socioeconomic factors in the elderly (60 years and older) living in the capital cities with the oldest average populations in South America. Background: Oral diseases are a public health problem, frequently neglected in older adults. In recent years, the subjective assessment of psychological and social consequences of the problems related to oral health has been valued. One of the instruments used to estimate the Oral Health‐Quality of Life is the Geriatric Oral Health Assessment (GOHAI). Material and methods: Representative samples from SABE study (1999–2000) of Santiago (n = 1301), Buenos Aires (n = 1043), and Montevideo (n = 1450) aged 60 and over community‐dwelling people. We assessed OH‐QoL (GOHAI), self‐reported missing teeth, denture use, and self‐rated‐health, among other indicators. Logistic regression models(GOHAI < 58) for each city, adjusted by sex and age, were applied. Results: GOHAI average scores were higher in Montevideo (54.8 ± 6.1) than in Buenos Aires (53.1 ± 7.4) and Santiago (49.9 ± 8.6). A pronounced gradient of the oral condition and GOHAI scores were observed within the three‐cities. Denture use ‐less prevalent in Santiago and more common among women‐ is a protective factor against a poor OH‐QoL. Conclusion: Socioeconomic inequalities in oral health status and OH‐QoL are observed in the three cities. The increasing life expectancy emphasizes the need to integrate prevention and treatment efforts, as a way to improve OH‐QoL over the course of a lifetime.     

The development of the SGI-16: a shortened sensory gating deficit and distractibility questionnaire for adults with ADHD

The Sensory Gating Inventory (SGI) is a questionnaire composed of 36 items designed to investigate abnormal perception related to the inability to control sensitivity to sensory stimuli frequently reported in adult with ADHD. This questionnaire can be considered too lengthy to be taken by people with ADHD, and a shortened version is needed. One hundred and sixty-three adults with ADHD responded to the SGI-36. An item reduction process took into account both the results of statistical analyses and the expertise of a steering committee. Construct validity, reliability, and external validity were tested for a short version (16 items). The structure of the SGI-16 was confirmed by principal components factor analysis. Cronbach’s alpha coefficients ranged from 0.78 to 0.89. The SGI-16 dimension scores were highly correlated with their respective SGI-36 dimension scores. The SGI-16 seems to be both appropriate and useful for use in clinical practice to investigate perceptual abnormalities in adults with ADHD.     

Oral health-related quality of life--associations with oral health and conditions in Swedish 70-year-old individuals

doi: 10.1111/j.1741‐2358.2011.00495.x Oral health–related quality of life – associations with oral health and conditions in Swedish 70‐year‐old individuals Objective: The aim of this study was to evaluate oral health–related quality of life (OHRQoL) in relation to different chronic oral conditions and perception of oral health among elderly individuals. Background: Health‐related quality of life is important to assess and understand the impact of different diseases and conditions on individuals’ well‐being. Material and methods: Randomly selected 70‐year‐old individuals (N = 561) were included in this analysis. They were clinically examined and answered a questionnaire. Variables used were perceived oral health, satisfaction with appearance of teeth, problems with chewing and dry mouth, burning mouth syndrome, dental anxiety and dental visiting habits. To measure the participants′ perception of the impact of oral conditions on their well‐being, the Oral Health Impact Profile (OHIP‐14) was used. Results: The OHIP‐14 distribution of sum of scores showed a floor effect but revealed acceptable psychometric properties with regard to reliability and validity. Multivariable logistic regression revealed three highly predictive variables for individuals with high OHIP‐14 scores: using dentures, having chewing problems and being dissatisfied with appearance of teeth. Conclusion: Use of dentures, having chewing problems and being dissatisfied with appearance of teeth are associated with high OHIP‐14 sums, indicating strong influence on OHRQoL.     

Validation of the Brazilian versions of two inventories for measuring oral health‐related quality of life of edentulous subjects

doi: 10.1111/j.1741‐2358.2010.00417.x
Validation of the Brazilian versions of two inventories for measuring oral health‐related quality of life of edentulous subjects Objectives: To analyse the validity of the Brazilian versions of OHIP‐EDENT and GOHAI as assessment tools of edentulous subjects’ OHRQoL. Background: Inventories for measuring oral health‐related quality of life (OHRQoL) are important in clinical studies regarding oral rehabilitation. However, there is a need for comprehensive validation after translation into different cultural settings. Materials and methods: The sample comprised of 100 complete denture wearers (29 men, 71 women, mean age of 65.2 ± 9.9 years). The associations between each OHRQoL inventory and other variables served as measurements of construct validity. Data analysis comprised the Spearman correlation test as well as multiple regression using the OHRQoL inventories as dependent variables and the other scales as determinants. Results: Both OHRQoL inventories showed good correlation with denture satisfaction, whereas lower correlation coefficients were found among the inventories and the HAD subscales. Denture satisfaction alone explained 48% and 39% of the variance found for the OHIP‐EDENT and GOHAI, respectively, as assessed by multiple regression. A smaller effect was found for OHIP‐EDENT. Conclusion: Both OHIP‐EDENT and GOHAI showed good construct validity for measurement of OHRQoL of edentulous subjects.     

Validation of a Sinhalese translation of the Oral Health Impact Profile-14 for use with older adults

Objective : To test the psychometric properties of a Sinhalese translation of the OHIP‐14 scale for use among older adults in Sri Lanka. Design : A cross‐sectional survey. The English version of the OHIP‐14 was translated in to Sinhalese, pre‐tested and subsequently administered to the subjects by a trained interviewer. Setting : Moratuwa — a densely populated urban area in the Western province of Sri Lanka. Subjects: 585 individuals aged 60 years and above. Main outcome measures : Reliability of the translated scale was assessed in terms of internal consistency using Cronbach's alpha. Construct validity was evaluated by examining the associations between perceived oral health status, perceived need for dental care and the OHIP scores. Results : Cronbach's alpha of the translated scale was 0.93. Corrected item‐total correlation coefficients ranged from 0.53–0.80. The highly significant associations between perceived oral health status, perceived need for dental care and the OHIP scores support the construct validity of the translated scale. Conclusion : The Sinhalese translation of the OHIP‐14 is a valid and reliable instrument to measure oral health related quality of life in older adults of Sri Lanka.     

Development and Validation of a Questionnaire Assessing Fears and Beliefs of Patients with Knee Osteoarthritis: The Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ)

Objective

We aimed to develop a questionnaire assessing fears and beliefs of patients with knee OA.

Design

We sent a detailed document reporting on a qualitative analysis of interviews of patients with knee OA to experts, and a Delphi procedure was adopted for item generation. Then, 80 physicians recruited 566 patients with knee OA to test the provisional questionnaire. Items were reduced according to their metric properties and exploratory factor analysis. Reliability was tested by the Cronbach α coefficient. Construct validity was tested by divergent validity and confirmatory factor analysis. Test–retest reliability was assessed by the intra-class correlation coefficient (ICC) and the Bland and Altman technique.

Results

137 items were extracted from analysis of the interview data. Three Delphi rounds were needed to obtain consensus on a 25-item provisional questionnaire. The item-reduction process resulted in an 11-item questionnaire. Selected items represented fears and beliefs about daily living activities (3 items), fears and beliefs about physicians (4 items), fears and beliefs about the disease (2 items), and fears and beliefs about sports and leisure activities (2 items). The Cronbach α coefficient of global score was 0.85. We observed expected divergent validity. Confirmation factor analyses confirmed higher intra-factor than inter-factor correlations. Test–retest reliability was good, with an ICC of 0.81, and Bland and Altman analysis did not reveal a systematic trend.

Conclusions

We propose an 11-item questionnaire assessing patients'' fears and beliefs concerning knee OA with good content and construct validity.     

Basic Scale on Insomnia complaints and Quality of Sleep (BaSIQS): Reliability,initial validity and normative scores in higher education students

Based on successive samples totaling more than 5000 higher education students, we scrutinized the reliability, structure, initial validity and normative scores of a brief self-report seven-item scale to screen for the continuum of nighttime insomnia complaints/perceived sleep quality, used by our team for more than a decade, henceforth labeled the Basic Scale on Insomnia complaints and Quality of Sleep (BaSIQS). In study/sample 1 (n?=?1654), the items were developed based on part of a larger survey on higher education sleep–wake patterns. The test–retest study was conducted in an independent small group (n?=?33) with a 2–8 week gap. In study/sample 2 (n?=?360), focused mainly on validity, the BaSIQS was completed together with the Pittsburgh Sleep Quality Index (PSQI). In study 3, a large recent sample of students from universities all over the country (n?=?2995) answered the BaSIQS items, based on which normative scores were determined, and an additional question on perceived sleep problems in order to further analyze the scale’s validity. Regarding reliability, Cronbach alpha coefficients were systematically higher than 0.7, and the test–retest correlation coefficient was greater than 0.8. Structure analyses revealed consistently satisfactory two-factor and single-factor solutions. Concerning validity analyses, BaSIQS scores were significantly correlated with PSQI component scores and overall score (r?=?0.652 corresponding to a large association); mean scores were significantly higher in those students classifying themselves as having sleep problems (p?<?0.0001, d?=?0.99 corresponding to a large effect size). In conclusion, the BaSIQS is very easy to administer, and appears to be a reliable and valid scale in higher education students. It might be a convenient short tool in research and applied settings to rapidly assess sleep quality or screen for insomnia complaints, and it may be easily used in other populations with minor adaptations.     

Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia

doi:10.1111/j.1741‐2358.2009.00344.x
Oral health‐related quality of life in patients receiving home‐care nursing: associations with aspects of dental status and xerostomia Objective: To explore the differences in oral status, dental attendance and dry mouth problems between patients with long‐term disease with high and low scores on Oral Health Impact Profile 14 (OHIP 14) and how patients cope with oral problems such as xerostomia and a reduced ability to brush their teeth. Background: There has been a lack of studies of oral health and oral health‐related quality of life in the frail elderly within the community services. Materials and methods: A cross‐sectional questionnaire study was conducted with 137 patients receiving home‐care nursing. Structured interviews were conducted by student nurses using OHIP‐14, items from the Xerostomia Inventory and questions concerning dental visit habits, brushing of teeth and data from medical records. Results: Eighty‐three per cent of patients had natural teeth and 60% had only natural teeth. ‘Natural teeth only’ indicated a low score on OHIP‐14. Problems with brushing and items concerning xerostomia indicated a high score on OHIP‐14. Contrasts in the assessments concerning brushing of teeth and xerostomia indicated low priority from the patients themselves and the nursing staff. Conclusion: Community health services should focus upon oral health. Both patients and nurses should assess the need for regular brushing of teeth carried out by home‐care nurses. Assessment and treatment of dry mouth problems should have higher priority.
