Randomized clinical trial of total vs. subtotal hysterectomy: validity of the trial questionnaire.

BACKGROUND: To ensure the internal validity of a trial it is recommended to undertake a validation study of the method measuring the outcome. AIMS: To validate a self-administered, postal questionnaire (http://www.gyncph.suite.dk/praes/gimbel/gihtm) used for measuring the outcomes of a randomized clinical trial of total vs. subtotal abdominal hysterectomy. METHODS: A study of the content validity (10 patients) and a combined qualitative and quantitative validation study (20 patients) were performed. RESULTS: The median kappa of the 74 questions was 0.71 (range 0.22-1.00) and the median overall agreement was 0.76 (range 0.25-1.00). Five questions (7%) had kappa values below 0.40, 11 questions (15%) between 0.40 and 0.60, and 58 questions (78%) above 0.61. Three questions with a kappa value below 0.40 had an overall agreement of 0.75 or more. Significant logical inconsistencies were found in five questions, where the operation method was expected to be known. The qualitative validation resulted in a total of 80 comments. The number of comments for any given subject ranged from 0 to 12. The comments could be grouped and processed into four categories. CONCLUSIONS: The agreement was high. Inconsistencies regarding questions on the operation methods were found. Potential problems were identified in five questions (7%). The validation studies resulted in some changes to the questionnaire and we became aware of areas in which caution should be taken in the interpretation of the results of the randomized trial.

Child's health self-concept scale: its development and psychometric properties.

The Child's Health Self-Concept Scale (CHSCS) is an instrument designed to measure the collection of perceptions a child has concerning health and health-related behaviors. Its development was based on perceptions of children regarding "healthy" and "unhealthy" children. The original instrument was critiqued, revised, and tested. The estimation of reliability and validity was accomplished through a sample of 940 children. Critical analyses of the findings led to the conclusions that the CHSCS had moderate stability and high internal consistency reliability, evidence of content validity, but no evidence of construct validity. Additional research is needed to evaluate its potential usefulness for nursing research and practice.

Construction and validation of a body image rating scale: a preliminary study.

PURPOSE: To construct and validate a preliminary version of a scale for use in routine screening of body image disturbances in nursing practice. METHODS: A five-stage procedure consisting of item construction, analysis of content validity, analysis of reliability, analysis of construct validity, and analysis of the discriminant validity of the scale. FINDINGS: At the end of the current stage of development, the preliminary version of the scale consisted of 23 items, demonstrating stability, adequate internal consistency, and discriminant validity between subjects in the upper and lower groups of scores. CONCLUSIONS: Although the psychometric properties of the scale have been delineated, the scale needs further psychometric evaluation and testing in different settings/samples so its clinical validity and reliability can be confirmed. PRACTICE IMPLICATIONS: The preliminary version of the body image rating scale has the potential to provide the nurse with reliable and valid information about a person's mental image of his/her own body. Using it can help nurses to identify possible body image disturbances and to plan individual nursing interventions.

[Development of a self-administered questionnaire to assess women's satisfaction with maternity care].

OBJECTIVES: We describe the development and the validation of a French self-administered questionnaire which measures women satisfaction concerning care given during pregnancy. The analysis includes pregnancy monitoring, hospitalization for delivery and homecoming. METHODS: We considered the content validity, internal-consistency and the reproducibility by test-retest estimates. This survey also compared the characteristics of respondents and non-respondents. RESULTS: Response rate was 61% and the rate of reply per question was greater than 90%. Eleven dimensions are identified by principal-components analysis. Ten of them had good Cronbach's alpha coefficients (0.58 to 0.83). The convergence between open comments and questions and between the different methods to measure satisfaction was good. The test-retest estimates for each dimension were correct. CONCLUSION: This questionnaire is reliable. It is a valid tool for evaluation of satisfaction after pregnancy. Designed to be sent to the woman's residence 2 months after childbirth, it can be easily used in common practice.

Pressure ulcer scale for healing: derivation and validation of the PUSH tool. The PUSH Task Force.

Measuring progress toward healing is fundamental to the management of pressure ulcers. A method to assess progress of an individual ulcer over time is lacking. Given the limitations of currently available instruments and the need for a precise and practical method of monitoring healing in clinical practice, the National Pressure Ulcer Advisory Panel initiated the development of a new tool for measuring pressure ulcer healing. The key elements in developing an instrument include simplicity of use in clinical settings, validity for measuring whether ulcers are improving or worsening, and sensitivity to changes in the ulcer between observations. A new tool incorporating surface area, exudate amount, and surface appearance is proposed. Content validity, correlation validity, prospective validity, and sensitivity to change can be met by the proposed Pressure Ulcer Scale for Healing instrument.

Translation and validation of Arthritis Impact Measurement Scales 2 into Chinese: CAIMS2.

OBJECTIVE: To evaluate the validity, reliability, and cultural relevance of the Arthritis Impact Measurement Scales 2 (AIMS2) as a health assessment tool for Chinese-speaking patients with arthritis. METHODS: The cultural relevance, language equivalency, and content validity of the AIMS2, Chinese version (CAIMS2) were evaluated by an expert panel. Measurement performance was tested on 240 subjects (rheumatoid arthritis = 81, osteoarthritis = 77, healthy = 82). Subjects (n = 175) were retested within 2 weeks for testing of reliability. RESULTS: Three items were modified and 2 items were added, as suggested by the expert panel. Interitem reliability was satisfactory (intraclass correlation coefficient 0.8552-0.9594). Test-retest reliability of the CAIMS2 subscales ranged from 0.770 to 0.952 in subjects in whom the CAIMS2 was self administered. Significant score differences between patients with arthritis and healthy subjects were found in all 12 subscales, except for the support from family and friends and tension subscales. CAIMS2 subscale scores correlated with clinical and laboratory measures of disease activity and patients' perceived quality of life as measured using the Chinese version of the World Health Organization Quality of Life instrument. CONCLUSION: Empirical data support CAIMS2 is a valid and reliable health status measure for Chinese speaking patients with arthritis.

Reliability and validity of the Family Eating and Activity Habits Questionnaire.

OBJECTIVE: The purpose of this work was to develop and test an instrument that will identify the factors that facilitate childhood obesity and monitor the environmental changes and family behavior modifications associated with weight loss. DESIGN AND METHODS: The relevant factors that affect obesity and weight loss in children were divided into four scales: activity level, stimulus exposure, eating related to hunger, and eating style. We designed a questionnaire to be completed by the parents of the obese child aged 6-11 years. Scores accumulated were calculated separately for each member of the family. Higher numerical scores reflected less appropriate eating patterns. The questionnaire reliability (test-retest), internal consistency and ability to discriminate obese vs normal-weight children's behaviors was tested using a pilot population of 40 mothers not enrolled in a formal weight loss program. The questionnaire reliability (parents' report and spouse report) and predictive validity was tested using a selective population: 60 parents of obese children enrolled in a clinical intervention intended to treat childhood obesity with an environmental approach vs a dietary approach. RESULTS: The content validity of the questionnaire was evaluated by a team of ten experts. Cronbach's alpha was calculated to test internal consistency. Mean r was 0.83. Pearson's correlation coefficients were computed between test and retest scores for individual items and for the total score, and ranged from 0.78 to 0.90 (median 0.84) (P < 0.01 for all). Total score test-retest r was 0.85 (P < 0.01). The total family score was also higher in the families with an obese child compared to families with a normal-weight child, P < 0.01. No significant differences were noted between parent report and spouse report scores. The construct validity of the questionnaire was also supported by its high sensitivity to weight loss treatment. Weight loss in the child correlated highly with improvement in questionnaire score. CONCLUSIONS: The Family Activity and Eating Habits Questionnaire is reliable and internally consistent, and it is useful as an optional tool for planning an intervention program for childhood obesity.

The development and testing of an instrument to measure self-efficacy in individuals with epilepsy.

The purpose of this study was to develop and test an instrument to measure self-efficacy in persons with epilepsy. With Bandura's self-efficacy theory serving as the conceptual basis for instrument development, the study was divided into two phases, an instrument development phase and a reliability and validity assessment phase. In phase one, self-efficacy and epilepsy literature along with discussions with epilepsy patients served as sources for item derivation. A panel of experts reviewed the instrument for content validity. In phase two, testing of the instrument for reliability and validity was done using different groups of epilepsy patients. Reliability coefficients ranged from .81 for test-retest reliability to .93 for internal consistency. A strong positive correlation between self-efficacy and social support (r = .48, p less than .001) and between self-efficacy and self-management (r = .50, p less than .001) provided evidence to support the construct validity of the instrument.

Short musculoskeletal function assessment questionnaire: validity, reliability, and responsiveness.

BACKGROUND: A short questionnaire on functional status was designed for use in community-based outcome studies and in the management of individual patients who have musculoskeletal disease. As most musculoskeletal care is delivered in community practices, short, validated instruments are necessary to perform clinical studies on the effectiveness of treatment in this setting. METHODS: A forty-six-item questionnaire was created as an extension of the work to develop the longer, 101-item Musculoskeletal Function Assessment (MFA) questionnaire. The Short Musculoskeletal Function Assessment (SMFA) questionnaire consists of the dysfunction index, which has thirty-four items for the assessment of patient function, and the bother index, which has twelve items for the assessment of how much patients are bothered by functional problems. The SMFA questionnaire was evaluated for reliability, validity, and responsiveness in a population of 420 patients who had a musculoskeletal disease or injury. RESULTS: The SMFA questionnaire demonstrated excellent internal consistency and stability, with most values greater than 0.90. Content validity for the dysfunction and bother indexes was supported with very little skew (less than 1.00), few ceiling effects (less than 5 percent), and no floor effects. Convergent validity was supported with significant correlations between the SMFA dysfunction and bother indexes and the physicians' ratings of patient function (for example, activities of daily living, recreational and leisure activities, and emotional function [rho > or = 0.40]) and standard clinical measures (for example, grip strength and walking speed [r > or = 0.401). Convergent and discriminant construct validity of the SMFA indexes were demonstrated (p < 0.01) in comparisons with clinical, demographic, Short Form-36 (SF-36), and life-change data. The responsiveness of the SMFA questionnaire to change over time was demonstrated with standardized response means ranging from moderate (0.76) to large (-1.14) for patients who had changes in health status. CONCLUSIONS: The SMFA questionnaire may be used for clinical assessments of the impact of treatment in groups of patients who have musculoskeletal disease or injury. It also may be used in clinical settings to provide reliable and valid assessments of the health status of an individual patient.

Developing an outcomes infrastructure for nursing. The Outcomes Taskforce.

An infrastructure to support the evaluation of patient care sensitive to the intervention of nursing personnel is being developed within a major health maintenance organization. In addition to traditional administrative measures of care, the database infrastructure will include measures of the patient's functional status, knowledge and engagement in care and psychosocial well-being. These measures are believed to be particularly sensitive to the independent intervention of the nurse. Reported here are the structures in place to monitor and support the reliability and validity of the administrative data elements; algorithm elements created to account for missing data; the model for the first generation of successful practice reports and the results of a study establishing the content validity of the clinical data elements.

An evaluation of a measure of subjective oral health status in the UK.

OBJECTIVE: To evaluate the performance in the United Kingdom of an instrument to measure the subjective impact of oral conditions; that is, the functional restrictions and symptoms, as well as the disability and disadvantage experienced as a result of oral problems. BASIC RESEARCH DESIGN: The instrument tested was the Subjective Oral Health Status Indicators (SOHSI) that consists of a battery of eight subjective indicators and which has been developed and tested in Canada. A questionnaire containing these indicators was administered by post to two random samples of two hundred and fifty residents aged 60-65 years, one from an affluent and one from a deprived electoral ward in Liverpool. MAIN OUTCOME MEASURES: Reliability was assessed as test-retest, and internal consistency using Cronbach's alpha. Construct and concurrent validity were assessed by determining the association between the subjective indicators and dentate status, reported satisfaction and overall subjective assessment of oral health. The constituent concepts of the theoretical model on which the instrument is based were tested by correlating the subjective indicators and the self-reported number of teeth. CONCLUSIONS: The instrument was found to be reliable both in terms of test-retest reliability and internal consistency. It also demonstrated satisfactory construct and concurrent validity. Correlations between self-reported number of teeth and the subjective indicators confirm the strength of the theoretical model on which the instrument was based and provide further evidence of the content validity of this composite measure.

The UFS-QOL, a new disease-specific symptom and health-related quality of life questionnaire for leiomyomata.

OBJECTIVE: To create and validate a questionnaire for assessing symptom severity and symptom impact on health-related quality of life for women with leiomyomata. METHODS: The questionnaire was derived from focus groups of women with leiomyomata. Content validity was established through cognitive debriefings of women with leiomyomata and review by expert clinicians. Patients for the validation study were recruited from five gynecologists' offices, an interventional radiology department, and a University campus. Instruments used for validation were the Short Form-36, Menorrhagia Questionnaire, the Revicki-Wu Sexual Function Scale, and a physician and a patient assessment of severity. Item and exploratory factor analysis were performed to assess the subscale structure of the questionnaire. Psychometric evaluation was conducted to assess reliability and validity. Test-retest was performed on a random subset of the sample within 2 weeks of the initial visit. RESULTS: A total of 110 patients with confirmed leiomyomata and 29 normal subjects participated in the validation. The final questionnaire consists of eight symptom questions and 29 health-related quality of life questions with six subscales. Subscale Cronbach's alpha ranged from 0.83 to 0.95, with the overall health-related quality of life score alpha = 0.97. The Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire subscales discriminated not only from normal controls but also among leiomyomata patients with varying degrees of symptom severity. Test-retest reliability was good with intraclass correlation coefficients of 0.76-0.93. CONCLUSION: The UFS-QOL appears to be a useful new tool for detecting differences in symptom severity and health-related quality of life among patients with uterine leiomyomata. Additional study is underway to determine the responsiveness of the UFS-QOL to therapies for leiomyomata.

The IBS-36: a new quality of life measure for irritable bowel syndrome.

OBJECTIVE: We aimed to develop and validate a quality of life instrument for patients with irritable bowel syndrome (IBS). METHODS: Using focus groups, existing questionnaires, and literature reviews, five IBS patients and nine gastroenterologists compiled and pilot tested for content validity a 70-item questionnaire. The questionnaire was then administered to 107 IBS patients, and using these data, the 70-item questionnaire was reduced to 36 questions through statistical and consensus methodology. The IBS-36 questionnaire was tested for construct validity, reliability, reproducibility, and responsiveness using a gold standard of structured interviews by three gastroenterologists, the Medical Outcomes Study Short Form Quality of Life Questionnaire, and the Coping Resource Inventory. RESULTS: The IBS-36 consists of 36 questions scored on a 7-point Likert scale. It has a very high internal consistency (Cronbach's alpha = 0.95) and a high test-retest reliability (Spearman's r = 0.92) and correlates as hypothesized with the Medical Outcomes Study Short Form Quality of Life Questionnaire (p < 0.001), McGill pain scores (p < 0.001), and IBS patient-reported sleep, symptom, and pain scores (ps = 0.030, <0.001, and <0.001, respectively). CONCLUSIONS: The IBS-36 addresses all areas of quality of life affected by IBS and is easy to administer and score. The IBS-36 is a well-validated, condition-specific quality of life measure for IBS patients that is sensitive to clinical intervention and highly correlated with established quality of life measures and patient-reported symptom scores.

The revised Personal Lifestyle Questionnaire for early adolescents.

The purposes of this study were to revise the Personal Lifestyle Questionnaire (PLQ), a measure of positive health practices, for use with early adolescents and to provide evidence of reliability and validity for the revised PLQ instrument. The sample consisted of 224 seventh and eighth graders who responded to the revised PLQ and instruments measuring three theoretically relevant variables. Relative to the revised PLQ, content validity was established, construct validity was determined by support of three hypotheses derived from theoretical propositions, and a two-factor solution was accepted in factor analysis procedures using principal components analysis with Varimax rotation. Acceptable reliabilities were obtained on the total revised PLQ and Factor 1; the reliability for Factor 2 fell slightly below the acceptable standard.

Maternal sensitivity and attachment security in Thailand: cross-cultural validation of Western measures.

The purpose of this study was to examine the psychometric properties of Thai versions of the Maternal Behavior Q-Sort (MBQS), Caldwell's HOME, and the Attachment Q-set (AQS). A sample of 110 Thai mother-infant dyads were studied. The Content Validity Index (CVIs) of the Thai MBQS, HOME and AQS were between 91% and 99%. Internal consistency of the HOME was .71. Interobserver reliability of the MBQS, HOME, and AQS were .95, .87, and .87, respectively. Convergent validity was supported by finding a positive correlation between the MBQS and the HOME (r = .29, p < .001). A positive correlation of .45 (p < .001) between the scores of the MBQS and the AQS indicated concurrent validity of these scales. Study findings indicate the Thai MBQS, HOME, and AQS are reliable and valid in this Thai sample and suggest that the Thai versions reflect concepts similar to those in the original English versions.
