Reliability and validity of a Dutch Lymphoedema Questionnaire: Cross-cultural validation of the Norman Questionnaire

OBJECTIVE

To perform the cross-cultural validation process of the Dutch Norman Questionnaire (NQ), a questionnaire for the detection and characterisation of breast-cancer related lymphoedema (BCRL) using self-reported signs and symptoms.

METHODS

Test-retest reliability and construct (including convergent, divergent and known-groups validity), face and content validity were examined in breast cancer patients with (n = 30) and without (n = 30) lymphoedema. For concurrent validity, first, agreement between the diagnostic item of the NQ and a clinical diagnosis were analysed. Second, correlations between NQ scores and clinical arm volume assessment were tested.

RESULTS

Test-retest reliability was found to be strong to very strong (ICC 0.79-0.96) in the lymphoedema group and moderate to very strong ( ICC 0.64-0.99) in the non-lymphoedema group. Seventeen out of 20 hypotheses on convergent and divergent validity were accepted. There was good face, content and known-groups validity as well. For concurrent validity, agreement between evaluation methods was only 0.462. Moderate correlations were found between 6 out of 9 symptom scores (r = 0.422-0.630) of the NQ and clinical assessment.

CONCLUSION

The Dutch NQ is a reliable and valid questionnaire for the characterisation of BCRL using self-reported signs and symptoms. Only moderate agreement for the detection of BCRL was found.

Translation, Cross-cultural Adaptation and Reliability of Brazilian portuguese version of the DRAM Questionnaire for Psychometric Evaluation in Low Back Pain

Objective  Based on studies regarding pain physiology and its relation to emotional distress conditions, psychological evaluation became essential to determine the most favorable patient profiles to distinct therapeutic approaches. The Distress Risk Assessment Method (DRAM) has been developed as a screening instrument for patients with lumbar pain, classifying them in subgroups as normal, at risk, distressed somatic and distressed depressive, based on the two components of DRAM scores (Modified Somatic Perception Questionnaire [MSPQ] and Zung questionnaires). The objective of the present study is to translate and culturally adapt the DRAM to the Brazilian Portuguese language, and to determine the reliability of the final version.

Methods  As proposed by the International Quality of Life Assessment (IQOLA) method, a Brazilian Portuguese version of the DRAM has been applied to a sample of 85 individuals from 3 participant centers.

Results  The results confirmed the reliability and reproducibility of the DRAM in its Brazilian Portuguese final version: Cronbach alpha of 0.815 (MSPQ) and 0.794 (Zung) and intraclass correlation coefficient (ICC) of 0.688 (MSPQ) and 0.659 (Zung).

Conclusion  The presented DRAM version in Brazilian Portuguese is reliable and is available to clinical practice use.

Cross-cultural validation of the French version of the Lymphedema Functioning, Disability and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL)

PURPOSE

Upper limb lymphedema is a vexing morbidity that can occur after the treatment for breast cancer. The Lymphedema Functioning, Disability and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL) is a valid and reliable tool assessing problems in functioning in patients with breast cancer-related lymphedema. Until now, a French-language version was lacking. The aim of this study was to perform a cross-cultural validation of the French version of the Lymph-ICF-UL questionnaire.

METHODS

A forward-backward translation process between the original language (Dutch) and the target language (French) was performed. Psychometric properties of this final French version were examined in 50 participants.

RESULTS

Intraclass correlation coefficients for test-retest reliability ranged from 0.66 to 0.95. Cronbach's alpha coefficients for internal consistency were higher than 0.77. Face and content validity were very good because the scoring system was clear for all participants (100%), questions were understandable (100%), and all complaints due to BCRL were mentioned by 78% of the participants. Construct validity was moderate. Convergent validity was established since 3 out of 5 expected domains of the Lymph-ICF-UL showed a moderate correlation with expected domains of the 36-item Short-Form Health Survey. There was satisfactory divergent validity as 6 out of 9 hypotheses assessing divergent validity were accepted.

CONCLUSION

The French version of the Lymph-ICF-UL is a reliable and valid questionnaire and ready for use in clinical as well as in scientific practice.Implications for rehabilitationSince the introduction of more effective treatment modalities increasing the number of breast cancer survivors, the amount of patients dealing with lymphedema is rising likewise up to a pooled incidence rate of more than 16% of the women treated for breast cancer.The French version of the Lymph-ICF-UL is a reliable and valid questionnaire for assessing problems in functioning of patients with breast cancer-related lymphedema of the arm and/or hand.As the questionnaire provides patient information in the different domains of the International Classification of Functioning, Disability and Health, it facilitates evaluating the impact of breast cancer-related lymphedema on daily functioning.Based on the outcomes of the Lymph-ICF-UL treatment goals can be set, where after the questionnaire can be used to monitor long-term results of this treatment and self-care.

Perceived barriers to and facilitators of physical activity in people with knee osteoarthritis: Development of the Evaluation of the Perception of Physical Activity questionnaire

BACKGROUND

The physical activity (PA) level of individuals with knee osteoarthritis is lower than in the general population. International recommendations recommend a non-pharmacological intervention including a self-management education program, weight loss and an adapted exercise program. However, we have no scale assessing the perceived barriers to and facilitators of PA in this population.

OBJECTIVE

We constructed and validated a self-administered questionnaire assessing perceived barriers to and facilitators of regular practice of PA in people with knee osteoarthritis.

METHODS

Semi-structured interviews identified 24 barriers and facilitators. We developed a 24-item questionnaire, Evaluation of the Perception of Physical Activity (EPPA) that was completed by 548 individuals with knee osteoarthritis, to assess acceptability, construct validity, internal consistency and convergent validity. Participants also completed the Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and International Physical Activity Questionnaire (IPAQ). Reliability and sensitivity to change were evaluated in a second group of 168 people with knee osteoarthritis at a 3-week spa therapy resort.

RESULTS

Factorial analysis identified 17 items grouped into 4 subscales (Barriers, Facilitators, Motivation and Beliefs). The internal consistency was good for Barriers, Facilitators and Motivation subscales (Cronbach α>0.70) and intermediate for the Beliefs subscale (Cronbach α=0.64). The EPPA subscale scores were significantly correlated with KOFBeQ and WOMAC scores but not associated with IPAQ physical activity level. Reliability was good for all subscales, with intraclass correlation coefficients>0.60. A sensitivity to change was found for only the Beliefs subscale, with a moderate effect size.

CONCLUSIONS

The EPPA questionnaire has good psychometric properties and can help guide the management of knee osteoarthritis. It can be used in research for evaluating the perception of physical activity.

How to best measure quality of life in coeliac disease? A validation and comparison of disease-specific and generic quality of life measures

OBJECTIVE

Health-related quality of life (HRQoL) is an important outcome in chronic disease. Generic HRQoL questionnaires may not adequately reflect disease-specific challenges in coeliac disease. We investigated whether disease-specific HRQoL questionnaires add relevant information to generic measures that will better help to identify patients experiencing problems.

PATIENTS AND METHODS

We performed a cross-cultural validation of the Celiac Disease Quality Of Life-survey (CD-QOL), next we developed and validated a new disease-specific HRQoL questionnaire, and finally compared their predictive validity with the disease-generic RAND SF-36/SF-12 in 825 patients (mean age: 56.1±15.8 years) with (reported) biopsy-proven coeliac disease. Internal consistency and convergent, discriminative and predictive validity of the questionnaires was determined.

RESULTS

Two Dutch versions of the CD-QOL were validated, consisting of 14 and six items, respectively (CD-QOL-14-NL, CD-QOL-6-NL). We developed and validated the CeliacQ-27, which has 27-items across three subscales (Limitations, Worries and Impact on daily life), and a short seven-item version, the CeliacQ-7. All questionnaires had excellent psychometric properties and differentiated well between active disease and clinical remission and strict versus poor dietary adherence. The added value of the disease-specific questionnaires to the generic HRQoL measure to the explained variance of symptom burden and dietary adherence was limited.

CONCLUSION

HRQoL in patients with coeliac disease can easily be assessed by brief generic as well as disease-specific measures. Disease-specific questionnaires, however, provide more explicit information on disease-relevant areas of functioning.

Reliability and Validity of the Turkish Reflux Symptom Index

OBJECTIVE

To validate and assess reliability of the Turkish Reflux Symptom Index (T-RSI).

STUDY DESIGN

Cross-sectional case-control study.

MATERIALS AND METHODS

A Turkish version of the original American English RSI was developed. One hundred thirty-two patients with a Reflux Finding Score (RFS) > 7, and 162 healthy controls (HC) with RFS ≤7 were included in the study. To assess reliability, the T-RSI was scored twice, within a 7-14 day window. For construct validity, the scores obtained in the study group were compared to the scores from the HC group. A correlation between RSI and RFS was assessed to determine content validity. Finally, sensitivity and specificity of the index was calculated using a receiver operating characteristic curve analysis.

RESULTS

The T-RSI showed excellent internal consistency (Cronbach`s α = 0.912). Item-total correlation coefficients ranged between 0.572 and 0.773. The Pearson product-moment correlation test indicated that the T-RSI is a reliable tool (r = 0.931, n = 107, P < 0.001). There were significant difference between the study group and the HC group for the mean RSI scores (18.15 ± 7.31 and 7.88 ± 5.32, P < 0.001 respectively). The mean RFS score in the patients was 12.57 and the correlation between RFS score and RSI score was high (r = 0.704). According to the receiver operating characteristic curve analysis the area under curve of the T-RSI was 0.892. The optimal cut-off value was 12.5 with a sensitivity of 82.6% and a specificity of 84.6%.

CONCLUSION

The T-RSI is an easily administered, reliable, and valid instrument for assessing symptoms thought to be related to laryngopharyngeal reflux. A score of T-RSI greater than 12.5 is similar to an RSI score of >13 considered symptomatic for laryngopharyngeal reflux.

Cross-cultural adaptation and psychometric properties of the Dutch version of the Hand Function Sort in patients with complaints of hand and/or wrist

BACKGROUND

Musculoskeletal complaints of arm, neck, and shoulder (CANS) can lead to loss of work productivity. To assess the functional consequences of impairments in work, patient-reported outcomes can be important. The Hand Function Sort (HFS) is a 62-item pictorial questionnaire that focuses on work task performance. The aims of this study were the cross-cultural adaptation of HFS into HFS-Dutch Language Version (HFS-DLV) (Part I) and determining construct validity, internal consistency, test-retest reliability, responsiveness and floor/ceiling effects of HFS-DLV (Part II).

METHODS

I: Translation into Dutch using international guidelines. II: Construct validity was assessed with Spearman's correlation coefficients between the HFS-DLV and the Dutch version of the QuickDASH, PRWHE, PDI, RAND-36, NRS-pain, and work ability score. Internal consistency was assessed using Cronbach's α and reliability by a test-retest procedure. A global rating scale of change was used after 4-8 weeks of hand therapy to determine responsiveness.

RESULTS

I: Forty patients were included, and no items were changed. II: 126 patients with hand, wrist, and/or forearm disorders classified as specific or nonspecific CANS. Six predefined hypotheses (50%) were confirmed. Cronbach's α: 0.98. Test-retest reliability: ICC of 0.922. AUC of 0.752. There were no floor/ceiling effects.

CONCLUSIONS

I: Translation process into the HFS-DLV went according to plan. II: For construct validity, the presumed direction of correlations was correct, but less than 75% of hypotheses were confirmed. Internal consistency was high, suggesting redundancy. Reliability and responsiveness of the HFS-DLV were good. HFS-DLV can be used in research or clinical practice for Dutch patients with CANS, to evaluate self-reported functional work ability.

Australian mental health caregiver burden: a smallest space analysis

OBJECTIVES

To explore Australian mental health carers' prioritisation of key elements of caregiving and establish the extent to which particular issues contribute to carer burden.

DESIGN

Cross-sectional survey.

SETTING

All Australian States and Territories.

PARTICIPANTS

Responses were received from 231 Australian mental health caregivers.

MAIN OUTCOME MEASURES

The Involvement Evaluation Questionnaire was used to assess caregiver burden.

RESULTS

Smallest space analysis identified three distinct regions, which we conceptualise as: 1) promoting the safety and health of mental health consumers; 2) impact of caring on caregivers' personal lives and 3) enabling daily living functional recovery of mental health consumers. The analysis demonstrates that carers are most concerned with enabling daily living functional recovery, for which the mean value was considerably higher than the personal impact and promoting safety and health regions. In terms of the individual questionnaire items, the issues of most importance are assisting with self-care, worrying about consumers' future, finances and general health, encouraging consumer involvement in activities and concerns over the treatment consumers are receiving.

CONCLUSION

Caregiving often came at significant personal cost. The burden that results from caring for mental health consumers could perhaps be alleviated through the expansion of psychiatric disability services, increasing government financial support and providing tailored psychosocial interventions that meet the needs of families.

Psychometric properties of the Mandarin Chinese version of the KIDSCREEN-52 health-related quality of life questionnaire in adolescents: a cross-sectional study

PURPOSE

To evaluate the psychometric properties of the Mandarin Chinese version of KIDSCREEN-52 health-related quality of life (HRQOL) questionnaire.

METHODS

We conducted a cross-sectional study with two cohorts of school-based data in the urban areas of Weifang, China. 4385 and 841 representative adolescents aged 11-17 years have recruited into the baseline and test-retest group, respectively. Psychometric analyses included feasibility, item and dimension properties, reliability, construct validity, measurement invariance, convergent and discriminant validity, and known-group validity.

RESULTS

The response rates of both baseline and test-retest surveys were more than 90%. Low missing values were found (0.02-1.92%) across ten dimensions. The measurement properties of items were satisfactory. Noteworthy ceiling effects were observed for ten dimensions (6.75-31.84%), while the observed floor effects were negligible (0.02-1.37%). Internal consistency was robust with Cronbach's alpha (0.819-0.959), while the test-retest reliability was acceptable with the ICCs (0.724-0.849). Confirmatory factor analysis confirmed the ten-dimensional structure and supported the configural and metric invariance across gender and age groups. The Pearson correlation coefficients between the KIDSCREEN-52 and the PedsQL™ 4.0 were stronger in comparable dimensions than those in less comparable dimensions, demonstrating the convergent and discriminant validity. In most dimensions, statistically significant and medium or large effect size differences were found across socioeconomic and mental health status, supporting the known-group validity.

CONCLUSION

These findings demonstrate that the Mandarin Chinese version of KIDSCREEN-52 seems to work well in a Chinese context, and is a psychometrically valid and reliable HRQOL instrument.

Validation of the French version of the LEIPAD in community-dwelling people aged 80 years and above

Background

Few studies have addressed health-related quality of life in community-dwelling individuals aged 80 years and above and very few self-assessment quality of life questionnaires have been formally validated in these populations. This study aimed to validate a French version of the LEIPAD, a self-administered questionnaire assessing the health-related quality of life of people aged 80 years and over.

Method

A cross-sectional study of people aged 80 years and over living at home in France was conducted. All subjects recruited were sent a letter explaining the study and requesting their consent to take part. Those who accepted then received the questionnaires, including the LEIPAD, which assesses health-related quality of life in the subjects aged 65 years and above. We assessed its psychometric properties: data completeness, score distribution, floor and ceiling effects, internal consistency, item-total correlations, inter-scale correlations, reliability and convergent validity with the Medical Outcome Study Short-Form 36 (SF-36).

Results

The results obtained from 184 older people (mean age of 83.9 years, standard deviation 3.3) showed very good acceptability (missing data between 1.1% and 11.4% for LEIPAD scales) Factor analysis of the instrument confirmed the multi-dimensional structure in seven independent scales similar to the original version. Good internal consistency (Cronbach’s alpha ranging from 0.68 to 0.87) and strong test-retest reliability of the LEIPAD scales (intraclass correlation coefficients ranging from 0.77 to 0.95) were found. Convergent validity with the SF-36 showed moderate to strong correlations, consistent with the hypotheses stated.

Conclusions

The validation of this specific questionnaire will make it possible to investigate individually the health-related quality of life of French older people living at home and will enable French-speaking investigators to contribute to national and international research projects.

Health-related quality of life in Switzerland: normative data for the SF-36v2 questionnaire

Purpose

Health-related quality of life (HRQOL) is an important concept to describe well-being of the general population and persons with diseases. The short form-36 (SF-36) is a widely used questionnaire assessing self-reported HRQOL in eight health domains. The aims of this study were to provide normative data for the SF-36 version 2 (SF-36v2) for all language regions in Switzerland and weighting coefficients to calculate two summary measures for physical and mental health.

Methods

A random representative (regarding age, sex, and language region) sample of people living in Switzerland aged 18–75 years in 2015 was eligible for our questionnaire survey. We calculated the eight health domain subscales for different subsamples based on sociodemographic characteristics. Two summary measures for physical and mental health were derived using data-based factor score coefficients and calculated for the subsamples.

Results

A total of 1209 persons completed the SF-36v2 (mean age 48.7 years, 58.1% women). The SF-36v2 was valid and reliable in Switzerland. Physical health was better in men (p = 0.012) and younger persons (p < 0.001). Mental health was better in men (p < 0.001) and older persons (p < 0.001). Regarding regional differences, we found better physical (p = 0.002) and mental (p < 0.001) health in German speaking persons compared to French and Italian speaking persons.

Conclusions

This paper presents the first SF-36v2 normative data for Switzerland, which are based on a recent study in a representative sample. Our normative data and weighting coefficients will enable future studies to compare HRQOL assessed by the SF-36 in healthy and diseased persons to a representative Swiss sample.

CROSS-CULTURAL ADAPTATION TO BRAZILIAN PORTUGUESE OF AN INSTRUMENT TO ASSESS TEASING DURING PHYSICAL/SPORTS ACTIVITY AMONG BRAZILIAN ADOLESCENTS

OBJECTIVE

To translate and adapt a questionnaire aimed to evaluate teasing during the practice of physical/sports activities in the adolescent population.

METHODS

The whole process had six stages: four translations, elaboration of a synthesis version, two back-translations, evaluation by a committee of experts, test of pre-final version with the target population, and presentation of final version to a committee of experts. Thirty-eight adolescents aged between 11 and 18 years participated in the pre-final version test, all of them from the 6th grade of elementary school to senior year of high school in a public school of the state of Santa Catarina.

RESULTS

The steps were strictly followed and then the need for change in the instrument emerged. The questions were altered according to discrepancies observed in back-translations, as well as suggestions by specialists to improve understanding and/or clarity and notes of adolescents participating in the pre-final test.

CONCLUSIONS

The instrument was translated into Portuguese and adapted to the Brazilian context according to the reality and culture of adolescents aged 11 to 18 years old, with possible understanding failures in younger age groups.

The moderating effect of social support on the relationship between physical health and suicidal thoughts among Chinese rural elderly: A nursing home sample

Suicide rate is relatively high among Chinese rural elderly. While there has been some exciting work on reporting and preventing suicide among community-dwelling elderly, only a few published studies have addressed the issues of rural nursing homes in China. This study aimed to investigate the relationship among perceived social support, physical health, and suicidal thoughts of the elderly living in Chinese rural nursing homes. It also examined the moderating effects of social support on the path from physical health to suicidal thoughts of the rural institutional elderly in China. This study investigated 205 participants aged 60 years and above in Chinese rural nursing homes. Participants' suicidal thoughts, perceived social support, and physical health were assessed. This study conducted descriptive analysis, Student's t-test, and Pearson's chi-square test to test how physical health and social support predicted suicidal thoughts, as well as the moderating effects of family's, friends', and others' social support on physical health and suicidal thoughts. Both physical health and perceived social support were significantly related to suicidal thoughts. Perceived social support from family, friends, and significant others moderated the relationship between physical health and suicidal thoughts. Findings of this study suggested that increasing social support and improving physical health would be effective in both suicide prevention and intervention for the residents in Chinese rural nursing homes.

Measurement invariance of the SF-12 among different demographic groups: The HELIUS study

AIM

To investigate whether items of the SF-12, widely used to assess health outcome in clinical practice and public health research, provide unbiased measurements of underlying constructs in different demographic groups regarding gender, age, educational level and ethnicity.

METHODS

We included 23,146 men and women aged 18-70 of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish, or Moroccan origin from the HELIUS study. Both multiple group confirmatory factor analyses (MGCFA), with increasingly stringent model constraints (i.e. assessing Configural, Metric, Strong and Strict measurement invariance (MI)), and regression analysis were conducted to establish comparability of SF-12 items across demographic groups.

RESULTS

MI regarding gender, age and education was tested in the ethnic Dutch group (N = 4,615). In each subsequent step of testing MI, change in goodness-of-fit measures did not exceed 0.010 (RMSEA) or 0.004 (CFI). Moreover, goodness-of-fit indices showed good fit for strict invariance models: RMSEA<0.055; CFI>0.97. Regarding ethnicity, RMSEA values of metric and subsequent models fell above 0.055, indicating violation of measurement invariance in factor loadings, thresholds and residual variances. Regression analysis revealed possible age-, education- and ethnicity-related DIF. Adjustment for this DIF had little impact on the magnitude of age and educational differences in physical and mental health, but ethnic inequalities in physical health-and to a lesser extent mental health-were reduced after DIF adjustment.

CONCLUSIONS

We found no evidence of violation of measurement invariance of the SF-12 regarding gender, age and educational level. If minor DIF would remain undetected in our MGCFA analyses, we showed that this would have negligible effect on the magnitude of demographic health inequalities. Regarding ethnicity, the SF-12 was not measurement invariant. After accounting for DIF, we observed a reduction of ethnic inequalities in health, in particular in physical health. Caution is warranted when comparing SF-12 scores across population groups with various ethnic backgrounds.

The Global Spine Care Initiative: a narrative review of psychological and social issues in back pain in low- and middle-income communities

PURPOSE

The purpose of this review was to describe psychological and social factors associated with low back pain that could be applied in spine care programs in medically underserved areas and low- and middle-income countries.

METHODS

We performed a narrative review of cohort, cross-sectional, qualitative and mixed methods studies investigating adults with low back pain using Medline and PubMed were searched from January 2000 to June 2015. Eligible studies had at least one of the following outcomes: psychological, social, psychosocial, or cultural/ethnicity factors. Studies met the following criteria: (1) English language, (2) published in peer-reviewed journal, (3) adults with spinal disorders, (4) included treatment, symptom management or prevention.

RESULTS

Out of 58 studies, 29 were included in this review. There are few studies that have evaluated psychological and social factors associated with back pain in low- and middle-income communities, therefore, adapting recommendations from other regions may be needed until further studies can be achieved.

CONCLUSION

Psychological and social factors are important components to addressing low back pain and health care providers play an important role in empowering patients to take control of their spinal health outcomes. Patients should be included in negotiating their spinal treatment and establishing treatment goals through careful listening, reassurance, and information providing by the health care provider. Instruments need to be developed for people with low literacy in medically underserved areas and low- and middle-income countries, especially where psychological and social factors may be difficult to detect and are poorly addressed.

Short Mood and Feelings Questionnaire for screening children and adolescents for plastic surgery: cross-cultural validation study

CONTEXT AND OBJECTIVE

Patient-reported outcome measurements assessing the emotional state of children and adolescents who seek plastic surgery are important for determining whether the intervention is indicated or not. The aim of this study was to cross-culturally adapt and validate the Short Mood and Feelings Questionnaire (child/adolescent and parent versions) for Brazilian Portuguese, test its psychometric properties and assess the emotional state of children and adolescents who seek plastic surgery. DESIGN AND SETTING: Cross-cultural validation study conducted in a plastic surgery outpatient clinic at a public university hospital.

METHODS

A total of 124 consecutive patients of both sexes were selected between September 2013 and February 2014. Forty-seven patients participated in the cultural adaptation of the questionnaire. The final version was tested for reliability on 20 patients. Construct validity was tested on 57 patients by correlating the Short Mood and Feelings Questionnaire (child/adolescent and parent versions) with the Strengths and Difficulties Questionnaire and the Rosenberg Self-Esteem scale.

RESULTS

The child/adolescent and parent versions of the Short Mood and Feelings Questionnaire showed Cronbach's alpha of 0.768 and 0.874, respectively, and had good inter-rater reliability (intraclass correlation coefficient, ICC = 0.757 and ICC = 0.853, respectively) and intra-rater reliability (ICC = 0.738 and ICC = 0.796, respectively).

CONCLUSIONS

The Brazilian-Portuguese version of the Short Mood and Feelings Questionnaire is a reproducible instrument with face, content and construct validity.The mood state and feelings among children and adolescents seeking cosmetic surgery were healthy.

Examining diabetes distress, medication adherence, diabetes self-care activities, diabetes-specific quality of life and health-related quality of life among type 2 diabetes mellitus patients

•

A five-factor theoretical model is proposed.

•

The SEM model evaluated relationships among three endogenous and two exogenous variables.

•

Higher levels of medication adherence had a significant direct effect on diabetes distress.

•

Self-care activities had significant direct effect on diabetes distress and HRQoL.

•

Diabetes-specific QoL had a significant effect on HRQoL.

Aims

Health-Related Quality of Life (HRQoL) has been increasing attention in health outcome studies. Factors that individually influence HRQoL, diabetes self-care behaviors, and medication adherence have been widely investigated; however, most previous studies have not tested an integrated association between multiple health outcomes. The purpose of this study was to formulate a hypothetical structural equation model linking HRQoL, diabetes distress, diabetes self-care activities, medication adherence and diabetes-dependent QoL in patients with Type 2 Diabetes Mellitus (T2DM).

Methods

A cross-sectional study design was employed, and 497 patients with T2DM were recruited from outpatient clinics in three public hospitals and one government clinic. The patients completed a series of questionnaires. The hypothetical model was tested using Structural Equation Modeling (SEM) analysis.

Results

The values of the multiple fit indices indicated that the proposed model provided a good fit to the data. SEM results showed that medication adherence (MMAS) had a significant direct effect on diabetes distress (PAID) (Beta = −0.20). The self-care activities (SDSCA) construct was significantly related to PAID (Beta = −0.24). SDSCA was found to have a significant relationship with HRQoL (SF-36) (Beta = 0.11). Additionally, diabetes distress had a significant effect (Beta = −0.11) on HRQoL of patients. Finally, ADDQoL had a significant effect on HRQoL (Beta = 0.12).

Conclusions

The various health outcome indicators such as self-care behaviors, diabetes distress, medication adherence and diabetes-dependent QoL need to be considered in clinical practice for enhancing HRQoL in those patients.

The economic burden of adult asthma in Cyprus; a prevalence-based cost of illness study

Background

Asthma is one of the main non-infectious diseases of the respiratory system with substantial economic burden worldwide. The objective of this study was to estimate the economic burden of adult asthma in Cyprus during 2015.

Methods

A retrospective probabilistic prevalence-based cost of illness model was developed to calculate the economic burden of asthma including direct and indirect costs. The bottom-up approach (person-based data) was used for the calculation of direct costs while for the calculation of indirect costs the approach of human capital was employed. In addition, bootstrapped sensitivity analysis with 1000 bootstrap simulations was performed in order to calculate a 95% Confidence Interval (CI).

Results

Mean patient cost of asthma in Cyprus in 2015 was estimated at €579.64 (95% CI: €376.90–€813.68). Direct costs accounted for 82.08% of the overall expenses, €475.75 per patient (95% CI: €296.94–€697.69). Indirect costs of €103.89 (95% CI: €49.59–€181.46) accounted for 17.92% of the overall expenses.

Conclusion

This was the first study in Cyprus, which used bootstrapped prevalence-based cost of illness model to estimate the cost of asthma. This study confirms that asthma is an expensive disease for the society. In addition, it provides important information and analysis of the economic consequences of asthma to policy makers in order to strengthen surveillance of the disease as well as draft the national health policy accordingly.

Validation of the Italian Version of the Caregiver Abuse Screen among Family Caregivers of Older People with Alzheimer's Disease

Introduction. Elder abuse is often a hidden phenomenon and, in many cases, screening practices are difficult to implement among older people with dementia. The Caregiver Abuse Screen (CASE) is a useful tool which is administered to family caregivers for detecting their potential abusive behavior. Objectives. To validate the Italian version of the CASE tool in the context of family caregiving of older people with Alzheimer's disease (AD) and to identify risk factors for elder abuse in Italy. Methods. The CASE test was administered to 438 caregivers, recruited in the Up-Tech study. Validity and reliability were evaluated using Spearman's correlation coefficients, principal-component analysis, and Cronbach's alphas. The association between the CASE and other variables potentially associated with elder abuse was also analyzed. Results. The factor analysis suggested the presence of a single factor, with a strong internal consistency (Cronbach's alpha = 0.86). CASE score was strongly correlated with well-known risk factors of abuse. At multivariate level, main factors associated with CASE total score were caregiver burden and AD-related behavioral disturbances. Conclusions. The Italian version of the CASE is a reliable and consistent screening tool for tackling the risk of being or becoming perpetrators of abuse by family caregivers of people with AD.

[Cross-cultural adaptation and validation of the PROMIS Global Health scale in the Portuguese language]

This study aimed to perform the cross-cultural adaptation and validation of the Patient-Reported Outcomes Measurement Information System (PROMIS) Global Health scale in the Portuguese language. The ten Global Health items were cross-culturally adapted by the method proposed in the Functional Assessment of Chronic Illness Therapy (FACIT). The instrument's final version in Portuguese was self-administered by 1,010 participants in Brazil. The scale's precision was verified by floor and ceiling effects analysis, reliability of internal consistency, and test-retest reliability. Exploratory and confirmatory factor analyses were used to assess the construct's validity and instrument's dimensionality. Calibration of the items used the Gradual Response Model proposed by Samejima. Four global items required adjustments after the pretest. Analysis of the psychometric properties showed that the Global Health scale has good reliability, with Cronbach's alpha of 0.83 and intra-class correlation of 0.89. Exploratory and confirmatory factor analyses showed good fit in the previously established two-dimensional model. The Global Physical Health and Global Mental Health scale showed good latent trait coverage according to the Gradual Response Model. The PROMIS Global Health items showed equivalence in Portuguese compared to the original version and satisfactory psychometric properties for application in clinical practice and research in the Brazilian population.

Developing an Instrument to Measure Keyboarding Style: Obtaining Content Validity

There is no observational instrument that can be used to document hand and finger use during computer keyboarding that may put a user at risk for musculoskeletal disorders of the upper extremity (MSD-UE). This paper describes a method used to obtain content validity for a new observational instrument, the PeCKS (Evaluation of Personal Computer Keyboarding Style), which can be used to document and assess these parameters of keyboarding style. Parameters of keyboarding style that might be risk factors for MSD-UE were developed through a review of the literature and interviews with MSD-UE experts. From these parameters a beta-1 version of the PeCKS was created and sent to seven experts to rate the content. Intraclass correlation coefficients were calculated to establish the agreement between raters concerning each parameter's importance as a risk factor for MSD-UE. There was good agreement among the raters about the importance of each parameter in the PeCKS (beta-1) and for the overall instrument. The instrument was subsequently modified and refined based on the experts' feedback.

Body Dysmorphic Symptoms Scale for patients seeking esthetic surgery: cross-cultural validation study

CONTEXT AND OBJECTIVE

Rhinoplasty is one of the most sought-after esthetic operations among individuals with body dysmorphic disorder. The aim of this study was to cross-culturally adapt and validate the Body Dysmorphic Symptoms Scale.

DESIGN AND SETTING

Cross-cultural validation study conducted in a plastic surgery outpatient clinic of a public university hospital.

METHODS

Between February 2014 and March 2015, 80 consecutive patients of both sexes seeking rhinoplasty were selected. Thirty of them participated in the phase of cultural adaptation of the instrument. Reproducibility was tested on 20 patients and construct validity was assessed on 50 patients, with correlation against the Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder.

RESULTS

The Brazilian version of the instrument showed Cronbach's alpha of 0.805 and excellent inter-rater reproducibility (intraclass correlation coefficient, ICC = 0.873; P < 0.001) and intra-rater reproducibility (ICC = 0.939; P < 0.001). Significant differences in total scores were found between patients with and without symptoms (P < 0.001). A strong correlation (r = 0.841; P < 0.001) was observed between the Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder and the Body Dysmorphic Symptoms Scale. The area under the receiver operating characteristic curve was 0.981, thus showing good accuracy for discriminating between presence and absence of symptoms of body dysmorphic disorder. Forty-six percent of the patients had body dysmorphic symptoms and 54% had moderate to severe appearance-related obsessive-compulsive symptoms.

CONCLUSIONS

The Brazilian version of the Body Dysmorphic Symptoms Scale is a reproducible instrument that presents face, content and construct validity.

International SF-36 reference values in patients with ischemic heart disease

PURPOSE

International reference data for the SF-36 health survey (version 1) are presented based on a sample of 5508 adult patients with ischemic heart disease.

METHODS

Patients with angina, myocardial infarction and ischemic heart failure completed the SF-36. Data were analyzed by diagnosis, gender, age, region and country within region and presented as mean ± standard deviation (SD), minimum, maximum, 25th, 50th and 75th percentile of the physical (PCS) and mental component summary (MCS) measures.

RESULTS

Mean PCS scores were reported as being more than one SD below the normal range (standardized mean of 50 ± 10) by more than half of the patient subgroups (59 %) with all of the mean MCS scores falling within the normal range. Patients with angina and patients with ischemic heart failure reported the poorest mean PCS scores with both diagnoses reporting scores more than one SD below the standardized mean. Females, older patients (especially >70 years) and patients from Eastern Europe reported significantly worse mean PCS scores than male, younger and non-Eastern European patients. The cardiac diagnosis had no effect on the mean MCS scores; however, females, younger patients (especially <51 years) and patients from Eastern Europe reported significantly worse mean MCS scores than male, older and non-Eastern European patients.

CONCLUSIONS

These international reference SF-36 values for patients with IHD are useful for clinicians, researchers and health-policy makers when developing improved health services.

Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS): Brazilian Portuguese translation, cultural adaptation and validation

OBJECTIVE

To translate, culturally adapt, and validate a Brazilian Portuguese version of the Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder (BDD-YBOCS).

METHODS

Ninety-three patients of both sexes seeking rhinoplasty were consecutively selected at the Plastic Surgery Outpatient Clinic of the Universidade Federal de São Paulo, Brazil, between May 2012 and March 2013. The BDD-YBOCS was translated into Brazilian Portuguese. Thirty patients participated in the cultural adaptation of the scale. The final version was tested for reliability in 20 patients, and for construct validity in 43 patients (correlation of the BDD-YBOCS with the Body Dysmorphic Disorder Examination [BDDE]).

RESULTS

Total Cronbach's alpha was 0.918. The BDD-YBOCS had excellent inter-rater (intra-class correlation coefficient [ICC] = 0.934; p < 0.001) and intra-rater reliability (ICC = 0.999; p < 0.001). Significant differences in BDD-YBOCS scores were found between patients with and without BDD symptoms (p < 0.001), and among patients with different levels of BDD severity (p < 0.001). A strong correlation (r = 0.781; p < 0.001) was observed between the BDDE and the BDD-YBOCS. The area under the receiver operating characteristic curve was 0.851, suggesting a very good accuracy for discriminating between presence and absence of BDD symptoms.

CONCLUSION

The Brazilian Portuguese version of the BDD-YBOCS is a reliable instrument, showing face, content and construct validity.

Quality of life from a randomized trial of open and endovascular repair for abdominal aortic aneurysm

Background

Long-term survival is similar after open or endovascular repair of abdominal aortic aneurysm. Few data exist on the effect of either procedure on long-term health-related quality of life (HRQoL) and health status.

Methods

Patients enrolled in a multicentre randomized clinical trial (DREAM trial; 2000–2003) in Europe of open repair versus endovascular repair (EVAR) of abdominal aortic aneurysm were asked to complete questionnaires on health status and HRQoL. HRQoL scores were assessed at baseline and at 13 time points thereafter, using generic tools, the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36®) and EuroQol 5D (EQ-5D™). Physical (PCS) and mental component summary scores were also calculated. Follow-up was 5 years.

Results

Some 332 of 351 patients enrolled in the trial returned questionnaires. More than 70 per cent of questionnaires were returned at each time point. Both surgical interventions had a short-term negative effect on HRQoL and health status. This was less severe in the EVAR group than in the open repair group. In the longer term the physical domains of SF-36® favoured open repair: mean difference in PCS score between open repair and EVAR −1·98 (95 per cent c.i. −3·56 to −0·41). EQ-5D™ descriptive and EQ-5D™ visual analogue scale scores for open repair were also superior to those for EVAR after the initial 6-week interval: mean difference −0·06 (−0·10 to −0·02) and −4·09 (−6·91 to −1·27) respectively.

Conclusion

In this study EVAR appeared to be associated with less severe disruption to HRQoL and health status in the short term. However, during longer-term follow-up to 5 years, patients receiving open repair appeared to have improved quality of life and health status.

Psychological distress, health, and socio-economic factors in caregivers of terminally ill patients: a nationwide population-based cohort study

PURPOSE

At some point in life, most people become caregivers to a terminally ill relative. Previous studies have shown that many caregivers experience psychological distress and declining physical health, but these studies have predominantly been conducted in specialized palliative care settings. Therefore, caregiver studies with a population-based approach are needed. We aimed to describe socio-economic characteristics, situational factors, pre-loss grief symptoms, depressive symptoms, caregiver burden, and health status in a general population of caregivers to terminally ill patients.

METHOD

We conducted a nationwide population-based cohort study. Caregivers were systematically recruited through patients registered with drug reimbursement for terminal illness in 2012. Data on socio-economic characteristics was mainly obtained from Danish registries, whereas data on situational factors, distress, and health was measured in questionnaires.

RESULTS

Of patients to responding caregivers (n = 3635), 89 % suffered from cancer, predominantly lung cancer (23 %). Of responding caregivers, 62 % were partners and 29 % were adult children. In total, one third of caregivers reported severe outcome, 15 % reported severe pre-loss grief symptoms, 16.1 % had moderate to severe depressive symptoms, and 12 % experienced high caregiver burden. Partners had the highest levels of pre-loss grief and depressive symptoms, while adult children reported the highest levels of caregiver burden.

CONCLUSIONS

From this cohort, which was estimated to be representative of caregivers to terminally ill relatives in the general population, we found high levels of pre-loss grief, depressive symptoms, and/or caregiver burden in one third of all caregivers. These findings call for increased focus on caregivers' need of support.

Cross-cultural adaptation and validation of the neonatal/infant Braden Q risk assessment scale

AIM

To translate into Brazilian Portuguese and cross-culturally adapt the Neonatal/Infant Braden Q Risk Assessment Scale (Neonatal/Infant Braden Q Scale), and test the psychometric properties, reproducibility and validity of the instrument. There is a lack of studies on the development of pressure ulcers in children, especially in neonates.

METHODS

Thirty professionals participated in the cross-cultural adaptation of the Brazilian-Portuguese version of the scale. Fifty neonates of both sexes were assessed between July 2013 and June 2014. Reliability and reproducibility were tested in 20 neonates and construct validity was measured by correlating the Neonatal/Infant Braden Q Scale with the Braden Q Risk Assessment Scale (Braden Q Scale). Discriminant validity was assessed by comparing the scores of neonates with and without ulcers.

RESULTS

The scale showed inter-rater reliability (ICC = 0.98; P < 0.001) and intra-rater reliability (ICC = 0.79; P < 0.001). A strong correlation was found between the Neonatal/Infant Braden Q Scale and Braden Q Scale (r = 0.96; P < 0.001).

CONCLUSION

The cross-culturally adapted Brazilian version of the Neonatal/Infant Braden Q Scale is a reliable instrument, showing face, content and construct validity.

The UP-TECH project, an intervention to support caregivers of Alzheimer's disease patients in Italy: preliminary findings on recruitment and caregiving burden in the baseline population

OBJECTIVES

The paper describes recruitment results and characteristics of the UP-TECH clinical trial sample, including level of care services use, informal caregiver burden and its determinants.

METHODS

UP-TECH is designed to test innovative care solutions for community-dwelling patients with moderate stage Alzheimer's disease and their caregivers in Italy. Four hundred and fifty patient-caregiver dyads were randomized into three arms receiving different combinations of services, composed of case management interventions, nurse visits, assistive technology and educational brochures. The research nurses administered a questionnaire comprising an in-depth socio-demographic assessment and several clinical scales, such as Novak's Caregiver Burden Inventory. Analyses of baseline data were conducted using uni- and bi-variate statistics. Linear regressions were computed to identify de-confounded correlates of caregiver burden.

RESULTS

Four hundred and thirty-eight patient-caregiver dyads were recruited and randomized. In our sample, patients are predominantly women (71.5%), with an average age of 81.5 years and a mean Mini-Mental State Examination score of 16.2. Caregivers are mostly women (66.2%) and offspring (55.7%), with a mean caregiver burden score of 27.6. They provide more than 50 hours of care per week, while receiving an almost negligible support from public services. Factors associated with caregiver burden are female gender, kinship and the patient's behavioral disturbances. The most important factor associated with lower burden is the employment of a live-in care worker.

CONCLUSION

The paper provides a comprehensive description of moderate stage Alzheimer's disease patients and their caregivers, suggesting useful markers of caregiver burden. The well-balanced randomization assures the reliability of the study data-set for prospective evaluation of care strategies.

Brazilian normative data for the Short Form 36 questionnaire, version 2

METHODS

The study Pesquisa Dimensões Sociais das Desigualdades (PDSD) (Social Dimensions of Inequalities) involves 12,423 randomly selected Brazilian men and women aged 18 years old or more from urban and rural areas of the five Brazilian regions, and the information collected included the SF-36 as a measure of health-related quality of life. This provided a unique opportunity to develop age and gender-adjusted normative data for the Brazilian population.

RESULTS

Brazilian men scored substantially higher than women on all eight domains and the two summary component scales of the SF-36. Brazilians scored less than their international counterparts on almost all of SF-36 domains and both summary component scales, except on general health status (US), pain (UK) and vitality (Australia, US and Canada).

CONCLUSION

The differences in the SF-36 scores between age groups, genders and countries confirm that these Brazilian norms are necessary for comparative purposes. The data will be useful for assessing the health status of the general population and of patient populations, and the effect of interventions on health-related quality of life.

Translation, cross-cultural adaptation and psychometric evaluation of yoruba version of the short-form 36 health survey

Background and objective

The Short-Form Health Survey (SF-36) is a valid quality of life tool often employed to determine the impact of medical intervention and the outcome of health care services. However, the SF-36 is culturally sensitive which necessitates its adaptation and translation into different languages. This study was conducted to cross-culturally adapt the SF-36 into Yoruba language and determine its reliability and validity.

Methods

Based on the International Quality of Life Assessment project guidelines, a sequence of translation, test of item-scale correlation, and validation was implemented for the translation of the Yoruba version of the SF-36. Following pilot testing, the English and the Yoruba versions of the SF-36 were administered to a random sample of 1087 apparently healthy individuals to test validity and 249 respondents completed the Yoruba SF-36 again after two weeks to test reliability. Data was analyzed using Pearson’s product moment correlation analysis, independent t-test, one-way analysis of variance, multi trait scaling analysis and Intra-Class Correlation (ICC) at p < 0.05.

Results

The concurrent validity scores for scales and domains ranges between 0.749 and 0.902 with the highest and lowest scores in the General Health (0.902) and Bodily Pain (0.749) scale. Scale-level descriptive result showed that all scale and domain scores had negative skewness ranging from −2.08 to −0.98. The mean scores for each scales ranges between 83.2 and 88.8. The domain scores for Physical Health Component and Mental Health Component were 85.6 ± 13.7 and 85.9 ± 15.4 respectively. The convergent validity was satisfactory, ranging from 0.421 to 0.907. Discriminant validity was also satisfactory except for item ‘1’. The ICC for the test-retest reliability of the Yoruba SF-36 ranges between 0.636 and 0.843 for scales; and 0.783 and 0.851 for domains.

Conclusion

The data quality, concurrent and discriminant validity, reliability and internal consistency of the Yoruba version of the SF-36 are adequate and it is recommended for measuring health-related quality of life among Yoruba population.

Validation of the Brazilian version of the Burn Specific Health Scale-Brief (BSHS-B-Br)

INTRODUCTION

Progressive increases in survival rates from burn trauma have shifted attention to patient rehabilitation and posttraumatic quality of life. The assessment of quality of life is strongly dependent on reliable instruments for its measurement. A literature review has revealed that the Burn Specific Health Scale-Brief (BSHS-B) questionnaire is the most commonly used instrument worldwide.

OBJECTIVES

The aim of this study was to translate the BSHS-B into the Portuguese language, adapt it culturally to the Brazilian population, and test its psychometric properties.

METHODS

The questionnaire was translated into Portuguese; culturally adapted; and tested for reproducibility, face validity, content validity, and construct validity. The translated version was tested on 92 patients with burns. Internal consistency was tested by means of Cronbach's alpha. Construct validity was performed by correlating the BSHS-B questionnaire with the Burn Specific Health Scale-Revised (BSHS-R), BurnSexQ-Escola Paulista de Medicina (EPM)/Universidade Federal De São Paulo (UNIFESP), the Rosenberg Self-Esteem Scale (RSES), and the Beck Depression Inventory (BDI).

RESULTS

Cronbach's alpha was 0.85. The Pearson correlation coefficients were significant at three time points of the reliability analysis. A significant correlation was observed between BSHS-B domains and BSHS-R, and between RSES and BDI domains. A significant correlation was also observed between BSHS-B and the BurnSexQ-EPM/UNIFESP social comfort and body image domains.

CONCLUSION

The BSHS-B questionnaire was translated into Portuguese. It is a reliable tool in this language, showing face, content, and construct validity. The modified instrument has been named BSHS-B-Br.

Outcomes of tricuspid annuloplasty with and without prosthetic rings: a retrospective follow-up study

BACKGROUND

The efficacies of tricuspid valve repair, risk factors for treatment failure and postoperative quality of life have not been thoroughly evaluated in patients with tricuspid insufficiency associated with rheumatic heart disease (RHD). We therefore reviewed our experience with ring and non-ring tricuspid annuloplasty for the treatment of functional tricuspid insufficiency (TI) in RHD.

METHODS

This retrospective, follow-up study involved 74 RHD patients who underwent either non-ring annuloplasty (De Vega procedure; 34 patients, 45.95 %) or ring annuloplasty (40 patients, 54.05 %) along with concurrent mitral or/and aortic valve replacement. Operation time, cardiopulmonary bypass time, aortic clamping time, intensive care unit stay and extubation time were recorded. Echocardiographic findings and Short Form (SF)-36 scores were compared between the two groups.

RESULTS

In hospital mortality and complications were similar in the two study groups (P = 0.6755). At 1 week, 1 month, 6 months, 1 year, 2 years and even longer after the operation, the Kaplan-Meier curve of freedom from mild and above recurrent TI showed significantly better efficacy in the ring annuloplasty group than the De Vega procedure group (log rank P = 0.0377). Risk factors for recurrent TI included high pulmonary artery systolic pressure (PASP) and non-ring annuloplasty (PASP: hazard ratio = 1.52; non-ring: hazard ratio = 1.42). The mental component summary score at 1 year after the operation did not significantly differ between the two groups (P = 0.6446), but the physical component summary score was significantly better in the ring annuloplasty group (P = 0.0037).

CONCLUSION

Compared with non-ring annuloplasty, ring annuloplasty was associated with improved survival, decreased TI recurrence and higher quality of life in RHD patients undergoing tricuspid valve repair combined with mitral and/or aortic valve replacement.

The relationships among social support and quality of life in persons living with HIV/AIDS in Jiangxi and Zhejiang provinces, China

Several empirical studies, particularly those conducted in developed countries, have linked social support to quality of life among persons living with HIV/AIDS (PLWA). However, few studies have been conducted in developing countries, such as China; therefore, the question of any association being present between social support and quality of life in PLWA in China remains unanswered. This retrospective cross-sectional study was conducted to examine the relationships between social support and quality of life among PLWA in the Jiangxi and Zhejiang provinces of China. A total of 377 PLWA participated in this study, and questionnaires used included demographics, the Chinese Medical Outcomes Study Short Form-36, and a Social Support Rating Scale, all of which were collected through face-to-face interviews between 1 March and 15 April 2013 in six different County Centers of Disease Control and Prevention in Jiangxi and Zhejiang provinces, and one hospital in the Jiangxi. The health-related quality of life score was 64.7±13.5 (out of a total score of 100), which was significantly lower than the national norm level of 78.2±15.9. The total score of social support was 29.4±7.8 (full score 66). The canonical correlation between social support and quality of participants' lives was shown to be statistically significant (p<0.0001). The relationship between subjective support and quality of life among PLWA was also significant (p=0.004). Subjective support and the use of social support showed a positive correlation with vitality, role-physical, and role-emotional, and a negative correlation with body pain. The current study suggests that PLWA with lower social support have diminished quality of life.

TuCASA questionnaire for assessment of children with obstructive sleep apnea: validation

OBJECTIVE

The aim of the present study was to validate The Tucson Children's Assessment of Sleep Apnea Study (TuCASA) questionnaire for use in the Brazilian population.

METHODS

Of the total 62 children who participated in the present study (27 girls), aged 4 to 11 years, 45 (72.6%) had sleep-disordered breathing (SDB) diagnosed by polysomnography, while 17 (27.4%) had no sleep disorders. Translation, back-translation, and pretesting were previously performed. The final Portuguese-language version of TuCASA was administered to the participants from May 2012 to August 2013. The interviewer was blinded to presence or absence of SDB. Cronbach's alpha for the overall scale (with 95% CI) and the effect of excluding any items were evaluated.

RESULTS

There was no difference among TuCASA items/score and the presence of SDB with either age or gender. The TuCASA had a Cronbach's alpha coefficient of 0.726 (95% CI 0.614 to 0.817), which denotes satisfactory internal consistency - a finding reinforced by evaluation of the effect of item exclusion on the questionnaire. Convergent validity was also satisfactory, in as much as most correlations were positive and significant.

CONCLUSION

The translated version of the TuCASA questionnaire was validated for Brazilian populations and proved to be a reliable, validated instrument that can be used in clinical practice for evaluation of children with symptoms of SDB.

Translation and psychometric properties of the persian version of the dialysis symptom index in hemodialysis patients

Background:

Hemodialysis patients have a high physical and psychosocial symptom burden. There is no valid and reliable tool for assessing symptoms of hemodialysis patients in Iran.

Objectives:

The aim of this study was to determine psychometric properties of the Persian version of the dialysis symptom index (DSI).

Patients and Methods:

The forward-backward procedure was applied to translate the DSI from English into Persian (Iranian language). The scale (Persian Version) was tested with a convenience sample of 95 patients with end-stage renal disease referred to main hemodialysis centers from December 2012 to June 2013. Validity was assessed using content, face and convergent validity. To test reliability, the kappa values were calculated for test-retest stability and the Cronbach alpha coefficients were also calculated for internal consistency.

Results:

The mean age of patients was 50.4 (SD = 15.72) years and % 61.1 of patients were male. The most commonly reported symptoms were fatigue, being irritable and nervous. Divergent validity was mostly supported by the pattern of association between DSI and SF-36 (r = -0.18– -0.48, P< 0.05). Cronbach’s alpha of the DSI was 0.90 and the weighted kappa ranged from 0.21 to 0.93, and it was greater than 0.4 for 25 of the 30 items.

Conclusions:

The Iranian version of the DSI had good psychometric properties and can be used to assess symptoms of hemodialysis patients.

The impact of significant other expressed emotion on patient outcomes in chronic fatigue syndrome

Objective: Previous literature has identified the importance of interpersonal processes for patient outcomes in chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), particularly in the context of significant other relationships. The current study investigated expressed emotion (EE), examining the independent effects of critical comments and emotional overinvolvement (EOI) in association with patient outcomes. Method: Fifty-five patients with CFS/ME and their significant others were recruited from specialist CFS/ME services. Significant other EE status was coded from a modified Camberwell Family Interview. Patient outcomes (fatigue severity, disability, and depression) were derived from questionnaire measures. Forty-four patients (80%) completed follow-up questionnaires 6-months after recruitment. Results: Significant other high-EE categorized by both high levels of critical comments and high EOI was predictive of worse fatigue severity at follow-up. High-critical EE was associated with higher levels of patient depressive symptoms longitudinally; depressive symptoms were observed to mediate the relationship between high critical comments and fatigue severity reported at follow-up. There were higher rates of high-EE in parents than in partners, and this was because of higher rates of EOI in parents. Conclusions: Patients with high-EE significant others demonstrated poorer outcomes at follow-up compared with patients in low-EE dyads. One mechanism for this appears to be as a result of increased patient depression. Future research should seek to further clarify whether the role of interpersonal processes in CFS/ME differs across different patient-significant other relationships. The development of significant other-focused treatment interventions may be particularly beneficial for both patients and significant others.

Understanding the experience of myotonic dystrophy. Mixed method study

Myotonic Dystrophy (DM) is a progressive multi-systemic disorder characterized by myotonia and muscle weakness where currently no effective treatment or cure to prevent or delay the disorder exists. This study used mixed methods to examine the experience of living with DM, in patients and their close relatives. Thirteen patients and eight next of kin responded completing Quality of Life and Psychological distress questionnaires in this cross-sectional study, and participating in a semi-structured interview. The findings indicate a higher level of anxiety and hopelessness in next of kin compared to patients, while patients were more depressed. Next of kin reported higher physical, but lower emotional quality of life than patients. Qualitative interviews confirmed the questionnaire findings. The findings from this study may be helpful in genetic counseling. Genetic counselors and geneticists should not only be aware of the burden of being a next of kin, but include discussions about opportunities to minimize the burden in families affected with DM. The findings may be of relevance in counseling for other types of neuromuscular disorders.

Effectiveness of gastric neurostimulation in patients with gastroparesis

BACKGROUND

Patients with gastroparesis have significantly delayed gastric emptying because of impaired nerve function. Gastric neurostimulation from Enterra Therapy provides electrical pulses to the stomach tissue that promotes stimulation of stomach smooth muscle, thereby enhancing gastric emptying. This study evaluates the effectiveness of Enterra Therapy (Medtronic, Minneapolis, Minnesota) in reducing symptoms and improving the quality of life of patients with drug-refractory gastroparesis.

MATERIAL AND METHODS

In this study 25 patients underwent minimally invasive, laparoscopic placement of the Enterra Therapy device. Patients were asked to rank their severity of symptoms and quality of life retrospectively by completing the Gastrointestinal Symptoms Rating Scale and Short Form 36 Health Survey with respect to their condition before and 6 months after initiation of Enterra Therapy.

RESULTS

Eighteen patients completed the surveys. Patients showed statistically significant improvement in their overall Gastrointestinal Symptoms Rating Scale scores and the mental health component of the Short Form 36 Health Survey.

DISCUSSION

Currently, Enterra Therapy has Humanitarian Use Device status, which means that more clinical evidence is needed to prove its effectiveness in gastroparesis. By showing that Enterra Therapy reduces symptoms of gastroparesis and improves patient quality of life, this study contributes to the increasing amount of data supporting its use and potential Food and Drug Administration approval.

Translation, adaptation and validation of a Portuguese version of the Moorehead-Ardelt Quality of Life Questionnaire II

The prevalence of obesity has increased worldwide. An assessment of the impact of obesity on health-related quality of life (HRQoL) requires specific instruments. The Moorehead-Ardelt Quality of Life Questionnaire II (MA-II) is a widely used instrument to assess HRQoL in morbidly obese patients. The objective of this study was to translate and validate a Portuguese version of the MA-II.The study included forward and backward translations of the original MA-II. The reliability of the Portuguese MA-II was estimated using the internal consistency and test-retest methods. For validation purposes, the Spearman's rank correlation coefficient was used to evaluate the correlation between the Portuguese MA-II and the Portuguese versions of two other questionnaires, the 36-item Short Form Health Survey (SF-36) and the Impact of Weight on Quality of Life-Lite (IWQOL-Lite).One hundred and fifty morbidly obese patients were randomly assigned to test the reliability and validity of the Portuguese MA-II. Good internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.80, and a very good agreement in terms of test-retest reliability was recorded, with an overall intraclass correlation coefficient (ICC) of 0.88. The total sums of MA-II scores and each item of MA-II were significantly correlated with all domains of SF-36 and IWQOL-Lite. A statistically significant negative correlation was found between the MA-II total score and BMI. Moreover, age, gender and surgical status were independent predictors of MA-II total score.A reliable and valid Portuguese version of the MA-II was produced, thus enabling the routine use of MA-II in the morbidly obese Portuguese population.
