RESUMO
Postural control is a skill associated with most motor activities and is essential for the performance of activities of daily living. People with intellectual disabilities (ID) present postural control deficits that can be attributed to several causes. The aim of this study was to determine whether postural control and physical fitness could explain the cognitive impairment and support needs in this population. A cross-sectional pilot study was conducted with 18 people with ID. Data collection was based on assessments for postural control (Mini BESTest and Berg Balance Scale) and physical fitness (Senior Fitness Test). The data were analyzed using linear regression models. Anticipatory postural adjustments were associated with support needs, explaining up to 45% of these. Consecutive postural adjustments and upper limb strength were less significantly associated with support needs. However, none of the variables used explained cognitive impairment in ID. Knowledge of the relationships and behavior of the different measurement tools is essential for the development of appropriate interventions in this population.
RESUMO
Clinical tests for the evaluation of balance in people with intellectual disability that have been most commonly used depend on the subjective evaluation of the evaluator, easily reach the ceiling effect and are poorly sensitive to small changes; but new tests have been developed, such as the Six Spot Step Test. The aim of this study was to determine the validity and within-day and day-to-day test-retest reliability of the Six Spot Step Test in people with intellectual disability. A descriptive cross-sectional study was conducted with 18 people with intellectual disability. The participants conducted the Six Spot Step Test three times and a set of five clinical tests for the balance assessment. The relative reliability was excellent (Intraclass Correlation Coefficient (ICC) = 0.86 - 0.97), and the absolute reliability ranged between 4.7% and 7.3% for coefficient variation and between 0.6 and 1.2 for the standard error of measurement. Linear regression models showed that that test can explain the results of the Timed Up & Go, Four Square Step Test and the Berg Balance Scale. The Six Spot Step Test proved to be as valid and reliable for the evaluation of dynamic balance in people with intellectual disability as the most frequently used tests for the clinical evaluation of postural control.
RESUMO
INTRODUCTION: Allergen immunotherapy is a long-term treatment that has been associated with patient adherence issues. The aim of the study was to increase the knowledge on compliance of patients allergic to house dust mites, receiving sublingual immunotherapy (SLIT). METHODS: A retrospective observational study was performed in 53 Spanish allergy units. We enrolled patients undergoing the SLIT treatment for house dust mites including a scheduled control visit 12 months after initiating the therapy. We conducted a comprehensive assessment of compliance using three methods. In the first step, an allergist evaluated the patients according to the results of an interview and the existing medical records. The subjects taking more than 80% of the overall prescription were defined as compliant. The remaining noncompliant patients were divided into groups taking less than 25%, 25-50%, and 50-80% of the prescribed SLIT. In the second stage, we conducted the Morisky-Green test. Finally, the noncompliant patients were asked to fill a self-report assessment form. Data were stratified into age groups. The potential factors affecting compliance were also investigated. RESULTS: Overall, 380 subjects participated in the study. The compliance rate was 79.7%, and the treatment discontinuation rate was 22.5%, while 66.8% of patients were adherent (both compliant and continuing with the treatment). The results showed that children were the most compliant and adolescents the least compliant (86.6% and 60.9%, respectively). The main reason for noncompliance was "forgetting some doses" in 31.0% of the children, 48.0% of the adolescents, and 53.2% of the adults. Compliance was associated with the following factors: age, number of annual control visits, and reduction in symptomatic medication. CONCLUSION: Our results showed that two out of three patients with house dust mite-induced allergic rhinitis adhered to the SLIT treatment. Multidisciplinary and integral solutions are needed to improve the compliance, with special attention paid to adolescents. FUNDING: Stallergenes Greer Spain.

Chronic Obstructive Pulmonary Disease (COPD) impairs quality of life and presents symptoms that affect the lives of patients. Our study analysed the degree of concordance between the patients and their pulmonologists in the perception of the severity of symptoms. A cross-sectional, descriptive, multicentre study was conducted in patients with COPD. From a list of 10 symptoms (cough, dry mouth, chest pain, expectoration, wheezing/whistling in the lungs, depression/sadness/discouragement, fatigue/tiredness/general lack of energy, anxiety/nervousness, breathlessness/shortness of breath upon exertion and difficulty sleeping/sleep disorders) each investigator and patient assessed those which, in their opinion, most concerned or affected the patient. A total of 450 patients were included in the study (91.3% males, 66.7 years old (SD = 10.2), FEV1(%) 51.7% (SD = 12.7%)). At an aggregate level, breathlessness/shortness of breath, fatigue/tiredness and coughing were identified by patients and physicians as being the most relevant symptoms. However, according to the concordance analysis conducted with individual pairs (each pulmonologist with his/her patient), only 52.8% coincided when identifying the symptom that most concerned or affected the life of the patient. The concordance analysed by the Kappa index between patients and physicians was poor (<0.42). The degree of physician-patient concordance was greater in patients with more severe COPD. The patients and their pulmonologists identified the same three main symptoms of COPD but showed low concordance when assessing the impact of the symptoms of the illness.

BACKGROUND: The PERFORM Questionnaire is a 12-item scale developed for assessing fatigue in cancer patients in the clinical practice. It has advantages over other tools in that it is short and includes beliefs and attitudes of patients about fatigue. It was psychometrically validated in cancer patients with and without anemia. PURPOSE: We evaluated the usefulness of the PERFORM scale to measure fatigue in a large study focusing exclusively on anemic patients. METHODS: This was an observational, multicenter, prospective, 3-month study in cancer patients with hemoglobin (Hb)≤11 g/dl. Fatigue was assessed using the PERFORM questionnaire. The overall score ranges from 12 (no fatigue) to 60 (maximum fatigue). RESULTS: We included 667 patients: 54.1 % women, mean age 60 (standard deviation, 12) years. A highly significant, but mild correlation was observed between low baseline Hb and high patient perception of fatigue (r with PERFORM score=-0.215, p < 0.0001). Of the patients, 65.8 % improved Hb level during follow-up (increase of ≥1 g/dL and/or achieving >11 g/dL), which translated into a significant improvement in the PERFORM score [mean (95 % confidence interval (CI)] change, -1.2 (-0.04 to -2.4), whereas more fatigue was observed in patients without improvement in Hb [change (95 % CI) in PERFORM, +3.3 (1.5 to 5)]. In a multivariate linear regression analysis, the independent factors associated to fatigue at 3 months were a low Hb level, a low Karnofsky index, active chemotherapy, cancer treatment with palliative intention, and transfusion need in the last 3 months. CONCLUSIONS: Minimal increases or decreases in Hb of ≥1 g/dL were associated with meaningful changes in patient-perceived fatigue as measured with the PERFORM questionnaire. In addition to anemia severity, other factors such as active chemotherapy and advanced disease contribute to perception of fatigue by cancer patients.

BACKGROUND: Satisfaction with treatment is a patient-reported outcome shown to be associated with the patient's health-related decisions and treatment-related behavior, thereby influencing the chances of successful treatment, and is especially relevant in long-term treatment, such as allergen-specific immunotherapy (AIT). OBJECTIVE: We sought to assess the psychometric properties of the Satisfaction Scale for Patients Receiving Allergen Immunotherapy (ESPIA) questionnaire so as to determine the satisfaction of patients receiving AIT treatment. METHODS: An observational, longitudinal, multicenter study was performed on patients with allergic rhinitis (AR) undergoing AIT treatment. Sociodemographic, clinical, and patient-centered health outcomes data were gathered at the study visits. Feasibility, reliability, validity, and sensitivity to change of the prevalidated version of the ESPIA questionnaire were assessed. RESULTS: Four hundred twenty-nine patients were included (52.2% women, 33.6 years of age, 54.5% of the cases with intermittent AR and 62.5% with moderate AR). Low levels of missing items and ceiling/floor effects were found for the overall score of the ESPIA questionnaire. The overall Cronbach α value and intraclass correlation coefficient were 0.90 and 0.92, respectively. The overall score for the ESPIA questionnaire was strongly associated with months receiving AIT, AR type and intensity, presence of conjunctivitis, self-perceived health status, effect of AR on daily life, and expectations about the AIT treatment. The pattern of correlations obtained with other patient-centered health outcomes was consistent with expectations. The ESPIA questionnaire also showed good sensitivity to change for improved health status. CONCLUSION: The ESPIA questionnaire to assess patient satisfaction with respect to AIT treatment presented satisfactory psychometric properties for its use in clinical practice.

BACKGROUND: Allergen-specific immunotherapy (SIT) is a treatment capable of modifying the natural course of allergy, so ensuring good adherence to SIT is fundamental. Up until now there has not existed an instrument specifically developed to measure patient satisfaction with SIT, although its assessment could help us to comprehend better and improve treatment adherence and effectiveness. The aim of this study was to develop an instrument to measure adult patient satisfaction with SIT. METHODS: Items were generated from a literature review, focus groups with allergic adult patients undergoing SIT, and a meeting with experts. Potential items were administered to allergic patients undergoing SIT in an observational, cross-sectional, multicenter study. Item reduction was based on quantitative and qualitative criteria. A preliminary assessment of feasibility, reliability, and validity of the retained items was performed. RESULTS: An initial pool of 70 items was administered to 257 patients undergoing SIT. Fifty-four items were eliminated resulting in a provisional instrument with 16 items. Factor analysis yielded four factors that were identified as perceived efficacy, activities and environment, cost-benefit balance, and overall satisfaction, explaining 74.8% of variance. Ceiling and floor effects were negligible for overall score. Overall score was associated with the type and intensity of symptoms. CONCLUSION: This is the first attempt to develop a satisfaction with SIT measure from the perspective of the allergic patient, and evidence has been found in favor of its reliability and validity.
RESUMO
BACKGROUND: Exacerbations are a frequent cause of morbidity and mortality in COPD. It is crucial to identify risk factors for failure after treatment of exacerbations of COPD. This study evaluates the COPD severity score (COPDSS) as a predictor of clinical failure, together with other severity, activity and quality of life measurements, in patients with exacerbated COPD. METHOD: Multicenter, prospective, observational study in ambulatory patients with exacerbation of COPD. The patients completed the COPDSS, the London Chest Activities of Daily Living (LCADL) and the EuroQol 5D (EQ-5D). A follow-up visit was scheduled one month after presentation with the exacerbation to assess the clinical evolution. RESULTS: A total of 346 patients were included (mean age 68.5 years (SD=9.5 years and 90.7% male) and mean FEV(1)(% predicted) 46.9% (SD=17)). After one month, 28.2% of episodes were classified as failures, with half of them requiring hospital admission. Patients who failed were more frequently active smokers, with more severe dyspnoea at presentation and worse lung function. They had significantly worse scores of COPDSS, LCADL, EQ-5D index and EQ-5D visual analogue score (VAS) and shorter mean time walking per day. ROC analysis of relationship between COPDSS and failure gave AUC 0.72, which improved only to 0.77 when the other significant variables in univariate analysis were considered. CONCLUSIONS: Clinical failure after ambulatory treatment of exacerbation of COPD is frequent. Usual markers of severity (impaired lung function, active smoking and severe dyspnoea) are associated with failure; however, a short severity questionnaire (COPDSS) provides better predictive value than the usual variables.

PURPOSE: Fatigue is a symptom with a relevant impact on the daily lives of cancer patients and is gaining importance as an outcome measure. The Perform Questionnaire (PQ) is a new scale originally developed among Spanish-speaking patients for the assessment of perception and beliefs about fatigue in cancer patients. METHODS: An observational longitudinal multicenter study was carried out on cancer patients with fatigue. Fatigue-specific measures (FACT-F), generic health-related quality-of-life measures (NHP), and PQ were gathered at baseline and 3 months later. Feasibility, reliability (internal consistency and test-retest), validity, sensitivity to change, and minimally important differences were analysed. RESULTS: Four hundred thirty-seven patients were included in the study: 60.5% were women, the mean age was 59.1 years, the mean time from diagnosis was 2.2 years, 33.6% of patients had breast cancer, and 29.1% had anaemia (haemoglobin (Hb) <11 g/dL). Low levels of missing items and ceiling/floor effects (<10%) were found. The overall Cronbach's alpha and intraclass correlation coefficient were 0.94 and 0.83, respectively. The PQ score was associated with fatigue intensity, the need for a caregiver, and the Hb level. Its association was stronger with the FACT-F than with non-specific health measures (NHP). The PQ showed good sensitivity to change for improved and worsening health status. A minimally important difference of 3.5 was estimated in patients whose Hb level had improved by at least 1 g/dL. CONCLUSIONS: The PQ measured the attitudes and beliefs about fatigue among cancer patients in clinical practice and showed good psychometric properties among Spanish-speaking patients.

The objective of the study was to validate the Spanish version of the Liverpool Adverse Events Profile (LAEP). An observational, cross-sectional, multicenter study was carried out on patients with epilepsy treated with a stable dose of antiepileptic drugs. Patients completed the LAEP, Quality of Life in Epilepsy Inventory-31 (QOLIE-31), and Hospital Anxiety and Depression Scale (HADS). Two hundred sixty-six patients were recruited. The LAEP was completed in a short time, perceived as easy to complete, and there was no relevant information missing. Ceiling/floor effects were negligible. Internal consistency (Cronbach's alpha=0.84) and test-retest reliability (ICC=0.81) were satisfactory. LAEP scores consistently correlated with QOLIE-31 (r=0.71) and HADS (r=0.52-0.63) scores. When the LAEP was used to discriminate between patients with and without adverse events, the scores on the QOLIE and HADS corresponded. The Spanish version of the LAEP scale exhibits adequate psychometric properties, suggesting that it is an appropriate instrument to measure adverse events among Spanish-speaking patients with epilepsy.

OBJECTIVES: Existing instruments that measure the impact of cancer-related fatigue on health-related quality of life do not usually incorporate the attitudes, beliefs and perspectives of patients. This study aimed to develop an instrument to measure the impact of cancer-related fatigue on the health-related quality of life of cancer patients. METHODS: Items were generated from a literature review, focus groups of cancer patients and meetings with oncologists. Potential items were administered to cancer patients to facilitate item reduction, which was based on clinimetric and psychometric analyses and qualitative criteria. A preliminary assessment of feasibility, reliability and validity of the retained items was performed. RESULTS: An initial pool of 75 items was administered to 238 cancer patients. Fifty items were eliminated after statistical analysis and 13 in response to expert opinion, resulting in a provisional instrument with 12 items in 3 dimensions. These displayed acceptable internal consistency (Cronbach's alpha, 0.78-0.92) and their overall score was associated with fatigue intensity, extent of disease, intention of treatment and need of caregivers. CONCLUSION: The newly developed questionnaire, which measures the impact of cancer-related fatigue on oncology patients, has shown satisfactory feasibility, reliability and validity.

OBJECTIVES: To develop and validate an instrument to measure health-related quality of life (HRQOL) specific to patients with allergic rhinitis (AR) and primarily for use in Spanish and Spanish-speaking populations. METHODS: An initial item pool was generated from literature review, focus groups with AR patients, and consultations with clinical experts. Item reduction was performed using clinimetric and psychometric approaches after administration of the item pool to 400 AR patients. The resulting instrument's internal consistency, test-retest (2-4 weeks) reliability, known groups and convergent validity, and sensitivity to change were tested in a longitudinal, observational, multicenter study in 210 AR patients who also completed the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). RESULTS: The new questionnaire took a mean (SD) of 7.1 (5.4) minutes to answer. Floor and ceiling effects were less than 15% on all dimensions. Cronbach's alpha values and intraclass correlation coefficient values for six of the sevendimensions and the overall score exceeded 0.70. Statistically significant differences (P < 0.01) were observed on all ESPRINT-28 dimensions and the overall score between patients with mild (mean overall score 1.97, SD 0.99), moderate (mean overall score 2.78, SD 0.88), and severe AR (mean overall score 3.89, SD 0.87). Patients with persistent AR had worse scores (P < 0.05) on all dimensions than patients with intermittent AR. Correlations between the ESPRINT-28 and the RQLQ were generally as expected. Effect sizes for score changes between the two study visits ranged from 0.96 to 1.76 for individual dimensions and the overall score. CONCLUSIONS: This new, Spanish-developed instrument to measure HRQOL in AR patients has shown good reliability, validity, and sensitivity to change. It has also proved easy to use and administer.

BACKGROUND: Allergic Rhinitis and its Impact on Asthma (ARIA) differentiates mild from moderate/severe patients on the basis of 4 severity items. The high prevalence of moderate/severe patients suggests the need to differentiate between them. OBJECTIVES: To identify the categorization that maximizes discrimination between moderate and severe allergic rhinitis (AR) by using ARIA guidelines. METHODS: Observational, cross-sectional study. Clinical characteristics, nasal symptoms (Total Symptom Score 4), and health-related quality of life (HRQL; Rhinoconjunctivitis Quality of Life Questionnaire and Short Form 12) were assessed. The association of severity items (sleep, daily activities/sport, work/school, and troublesome symptoms) with symptoms and HRQL was analyzed using linear regression models. ANOVA and effect sizes were used to assess differences in symptoms and HRQL among groups defined by the number of affected ARIA items. RESULTS: Nontreated patients (N = 141) with moderate/severe AR were studied. All severity items showed a similar independent association with symptoms and HRQL scores, and there were no interaction effects, indicating that categorization of patients into moderate and severe could be based only on the number of items affected. Effect sizes were highest between patients with 4 affected ARIA items and those with 3, 2, or 1 affected item (effect sizes greater than 0.8 in all comparisons using Rhinoconjunctivitis Quality of Life Questionnaire and Short Form 12 Physical Composite Summary, and greater than 0.5 using the Total Symptom Score 4; P < .001). CONCLUSION: Using ARIA severity items, the criterion that best discriminates AR severity is considering moderate those with 1 to 3 affected items and severe those with 4. CLINICAL IMPLICATIONS: Discrimination between patients with moderate and severe AR should help to obtain homogeneous populations for both research and clinical purposes.

BACKGROUND: High rates of missing, non-applicable items and insufficient reliability have been frequently reported as limitations of the generic Quality of Life questionnaires for older patients. The Nottingham Health Profile (NHP) might be more suitable as it contains easy to respond (yes/no) items covering moderate-to-severe health deterioration. OBJECTIVES: To assess feasibility, reliability and validity of the NHP in disabled, older patients. DESIGN: Cross-sectional study. SETTING: Acute care hospital. SUBJECTS: 134 inpatients aged >or=65 with severe disability, abnormal cognitive function, or other persistent health problems precluding their discharge. METHODS: The (interviewer-administered) NHP, Mini-Mental State Examination (MMSE), Barthel Index, and diagnostic information were recorded. RESULTS: Completion rates varied from 98% of the 49 patients with normal cognition (MMSE >or=21) and 86.3% of the 51 with moderate cognitive impairment (MMSE 10-20), to 5.9% of the 34 with severe cognitive impairment (MMSE<10). Cronbach's alpha of the total NHP score was near 0.9 (0.82 and 0.87 for patients with MMSE >or= 21 and 10-20, respectively; p = 0.291). The correlation between 'Physical Mobility' of the NHP and Barthel Index was also similar in both cognitive groups (0.39 and 0.40). CONCLUSION: Interviewer-administered NHP is suitable, reliable and valid, even in patients with moderate cognitive function.

OBJECTIVE: The international development of the Parents' Index of Quality of Life in Atopic Dermatitis (PIQoL-AD), a quality of life (QoL) instrument specific to parents of children with atopic dermatitis (AD) is described. METHOD: The instrument was developed simultaneously in several countries. Its content was derived from 65 qualitative interviews with parents in the UK, Netherlands and Italy. The measure was then produced for the UK, Netherlands, Italy, Germany, France, US and Spain. Field-test interviews were conducted with approximately 20 patients in each country to assess face and content validity. A two time-point survey was conducted with between 45 and 328 parents in each country to finalise the instrument through application of the Rasch model and to evaluate the psychometric properties of the final instrument. RESULTS: Application of the Rasch model to the survey data identified the final 28-item version. All language versions had good item fit, test-retest reliability (above 0.85), internal consistency and promising validity. CONCLUSIONS: The PIQoL-AD is a valuable instrument for inclusion in clinical trials and routine clinical practice. It provides distinct and complementary information to that of existing dermatology-specific measures and has been shown to be responsive to changes in QoL in clinical trials.

BACKGROUND: The measurement of patient satisfaction with pain medication (SPM) is a potentially useful aid for health care decision-making, but no validated measures for SPM are known. OBJECTIVE: This study aimed to develop an instrument to assess this patient-reported outcome in primary care and to evaluate whether it satisfactorily fulfilled the required psychometric properties (ie, reliability, validity, and sensitivity to change). METHODS: The measure's content was obtained from literature reviews, focus groups, and expert opinion. A preliminary version of 14 self-administered items was obtained and tested in a prospective study in patients receiving pain medication. Item-total statistics and factor analysis were performed to obtain the final version. The final version was psychometrically validated by assessing feasibility, internal consistency (Cronbach's alpha), convergent validity (multivariant methods), discriminant validity in patients presenting pain relief (receiver operating characteristic curves), test-retest reliability (using the intraclass correlation coefficient [ICC] in patients maintaining medication), and sensitivity to change (in patients changing medication). RESULTS: A total of 1119 patients were recruited (626 women [55.9%]; mean [SD] age, 47.6 [15.36] years; primarily suffering musculoskeletal injury [50.7%]). Four items were deleted from the preliminary version owing to low item-scale correlation and/or factor loadings. The final factor analysis confirmed a 4-factor solution, which explained 81.4% of the variance in questionnaire scores. Adverse events, speed/duration of effect, functional benefit, and overall satisfaction dimensions were identified. Cronbach's alpha and ICC for the 10-item final version were >0.80 for the summary score and all dimensions. Pain-related characteristics (intensity, frequency, and degree of pain relief), but not patient-related characteristics, were independently associated with the summary score. The area under the curve was 0.78 for the summary score. Effect sizes and standardized response mean were > or = 0.84 for the summary score and all dimensions. CONCLUSION: The SPM questionnaire appears to have good acceptability as well as satisfactory psychometric properties, based on these analyses.

OBJECTIVES: The clinical course of irritable bowel syndrome (IBS) remains poorly known. In 209 IBS patients meeting Rome II criteria (137 females and 72 males) we evaluated: (1). changes in frequency and intensity of abdominal pain/discomfort, abnormal number of bowel movements, loose or watery stools, defecatory urgency, hard or lumpy stools, straining during bowel movements, and feeling of incomplete evacuation); (2). use of resources, HRQoL, and psychological well being. METHODS: Observational, prospective, multicenter study. Symptoms were registered in a diary over two 28-day periods with an interval of 4 wk; direct resource use and indirect costs were noted weekly. Three HRQoL questionnaires were administered. RESULTS: High-intensity symptoms were present on more than 50% of the days. Sixty-one percent were classified in the same IBS subtype on both occasions (kappa= 0.48), while 49% had the same symptom predominance and intensity (kappa= 0.40). The greatest instability was observed among diarrhea (D-IBS) and constipation (C-IBS) subtypes: only 46% and 51% remained in the same pattern with a tendency to shift to alternating diarrhea/constipation subtype (A-IBS); however, practically no patient changed from D-IBS to C-IBS, or vice versa. The most reliable symptom characteristic was frequency, followed by intensity and number of episodes. Symptom frequency and intensity were directly related to resource use and HRQoL impairment. CONCLUSIONS: IBS symptoms are instable over time and variables in intensity. Many patients with D-IBS or C-IBS move to A-IBS; however, shift from D-IBS to C-IBS, or vice versa, is very infrequent.

OBJECTIVES: Diagnosis of irritable bowel syndrome (IBS) and other functional bowel disorders (FBD) is based on symptom evaluation. Clinical criteria have changed over time, yielding different proportions of subjects fulfilling diagnostic requirements. According to new diagnostic criteria (Rome II), subjects considered some years ago to have IBS no longer do so. The aim of this article is to evaluate how patients diagnosed as having IBS according to original Rome criteria have been split, and to which clinical diagnosis they belong today. METHODS: Two hundred and eleven subjects meeting original Rome IBS diagnostic criteria were studied: 65 also met Rome II criteria while 146 did not. Subjects were extracted from an epidemiological survey, using home-based personal interviews, on 2000 subjects randomly selected as representative of the Spanish population. Clinical complaints, personal well-being, resource utilization, and health-related quality of life (HRQOL) were compared. RESULTS: Of the subjects meeting original Rome but not Rome II criteria, the present diagnosis should be: 40%"minor" IBS (IBS symptoms of less than 12 wk duration), 37% functional constipation, 12% alternating bowel habit, 7% functional diarrhea, 3% functional abdominal bloating, and 1% unspecified functional bowel disorder (FBD). Thus, 52 subjects (36%) should not be diagnosed with IBS because they really had other FBD, 59 (40%) because of symptoms consistent with IBD diagnosis but not the required duration or frequency, and 35 (24%) because of symptoms consistent with some other FBD diagnosis but not meeting the required duration. Clinical complaints, personal well-being, resource utilization, and HRQOL were more severely affected in IBS than in other FBD as a group, and in "major" rather than in "minor" forms. CONCLUSIONS: Many subjects meeting original Rome criteria for IBS do not meet Rome II criteria: approximately one quarter of subjects do not have sufficient symptom duration or frequency to be diagnosed with IBS and almost half are now considered as having other ("major" or "minor") FBD.

Antecedentes: Se han desarrollado dos instrumentos de calidad de vida relacionada con la salud (CVRS) específicos para dermatitis atópica, el Quality of life Index for Atopic Dermatitis (QoLIAD), para uso en pacientes adultos, y el Parents' Index of Quality of Life in Atopic Dermatitis (PIQoL-AD), para padres de pacientes pediátricos. Objetivo: Validar las versiones españolas de ambos cuestionarios. Métodos: Se administraron los instrumentos en un estudio observacional, multicéntrico y prospectivo (2 visitas), a dos grupos de pacientes. El grupo 1 incluyó pacientes adultos con dermatitis atópica y el grupo 2 padres de niños con dermatitis atópica. Se administraron adicionalmente el Dermatology Life Quality Index (DLQI) y el Índice de Bienestar Psicológico (IBP). Para cada cuestionario se evaluaron: efectos suelo y techo, fiabilidad interna y test-retest, validez convergente-divergente y validez de grupos conocidos. Resultados: Se incluyeron 83 pacientes (grupo 1) y 153 padres/madres (grupo 2). Para ambos grupos: los efectos techo y suelo oscilaron entre 0 y 9,2%; los coeficientes alfa de Cronbach oscilaron entre 0,88 y 0,90 y los coeficientes de Spearman entre 0,88 y 0,90. Los coeficientes de correlación con los cuestionarios comparadores fueron 0,79 (QoLIAD-IBP), 0,76 (QoLIAD-DLQI) y 0,52 (PIQoL-AD e IBP). Las puntuaciones en el QoLIAD fueron peores cuando peor fue el estado de salud y la intensidad autopercibida de la dermatitis atópica. Las puntuaciones en el PIQoL-AD fueron peores cuando peor fue el estado de salud. En los adultos (QoLIAD) las puntuaciones de CVRS fueron peores cuando la dermatitis afectaba generalmente al rostro; por el contrario, las puntuaciones del PIQoL-AD fueron peores cuando afectaba en general a las manos. Conclusiones: Las versiones españolas de ambos cuestionarios han mostrado una fiabilidad y una validez satisfactorias para ser utilizadas en esta población (AU)

BACKGROUND: Disturbed bowel habit, diarrhoea or constipation is a key manifestation of irritable bowel syndrome (IBS). In some patients, diarrhoea and constipation alternate, giving rise to the so-called alternating subtype. AIMS: To assess IBS subtype breakdown (constipation (C-IBS), diarrhoea (D-IBS) or alternating (A-IBS)) according to the Rome II criteria and patients' self-assessment, the predominance in the alternating subtype (i.e. constipation, diarrhoea or neither), and the medical and personal impact, including health-related quality of life (HRQoL), of the different IBS subtypes. SUBJECTS AND METHODS: Two thousand individuals selected randomly to represent the general population were classified as potential IBS subjects (n = 281) or as non-potential IBS subjects (n = 1719) according to a validated questionnaire. Bowel habit classification was determined using the Rome II IBS supportive symptoms. RESULTS: Among 201 subjects meeting the Rome I criteria, 15% presented with D-IBS, 44% presented with C-IBS, 19% presented with A-IBS, and 22% presented with normal bowel habit. Among the 63 subjects meeting the Rome II criteria, 23% presented with A-IBS. According to the subjects' self-assessment, of those meeting the Rome I criteria, 16% considered themselves to have D-IBS, 66% to have C-IBS and 18% to have A-IBS. In subjects meeting the Rome II criteria, 24% considered themselves to have A-IBS. Among those classified with A-IBS by the Rome II criteria, most considered themselves to be constipated. Regardless of the subtype self-classification, most subjects reported a normal frequency of bowel movements. Clinical manifestations in A-IBS were very similar to those of C-IBS but with the added presence of defecatory urgency. Abdominal discomfort/pain and frequency of visits to physicians were greater in the A-IBS subtype than in the other two IBS subtypes. HRQoL was affected similarly in all IBS subtypes. CONCLUSIONS: Approximately one-quarter of subjects with IBS belong to the A-IBS subtype by the Rome II criteria, although the majority consider themselves to be constipated; indeed, clinical manifestations are more akin to the C-IBS subtype than to the D-IBS subtype. Abdominal discomfort/pain and frequency of visits to physicians are greater in the A-IBS subtype than in the other two IBS subtypes, while HRQoL is impaired similarly.
