The quality of assessment of patients with chest pain: the development of a questionnaire to audit the nursing assessment record of patients with chest pain.

The quality of nursing and medical records has been a source of concern for many years (Audit Commission 1995). This study has two main purposes: firstly, to design an audit questionnaire to evaluate the quality of nursing assessment records of patients with chest pain; and secondly, to make some tentative conclusions about the quality of nursing assessment of patients with a chest pain in order to pinpoint areas that need further study. A sample of 30 patients was selected for this study on the basis of some well-defined inclusion criteria. The nursing assessment notes of these patients were evaluated using the audit questionnaire. It was found that the questionnaire was effective in gleaning appropriate information from the nursing notes to be able to derive some tentative conclusions about the quality of nursing assessment of patients with chest pain, i.e., on the whole nursing assessment was found to be superficially carried out, potentially making errors of omission and commission likely to occur. The inter-rater reliability of the questionnaire was found to be good. The questionnaire also seems to measure what it purports to measure (i.e. has content validity). However, this needs to be further checked by using a larger sample.

Comparing doctor- and nurse-led care in a sexual health clinic: patient satisfaction questionnaire.

BACKGROUND: A new model of comprehensive care nurse-led clinics has enabled experienced genitourinary medicine nurses to co-ordinate the first-line, comprehensive care of female patients presenting with sexually transmitted infections and other sexual health conditions and issues. AIM: This paper describes the development of a patient satisfaction questionnaire to compare the satisfaction of women attending nurse-led or doctor-led clinics at a central London genitourinary medicine clinic. METHODS: A previously validated questionnaire was adapted using the findings of qualitative interviews exploring patient expectations of the service. The draft questionnaire was tested for internal consistency, sub-scale homogeneity, construct validity and stability. The final version consisted of a 34 item, five-point Likert scale, which was found to be both reliable (Cronbach's alpha 0.91) and stable (test-retest 0.95). There was some evidence of construct validity. The questionnaire was then distributed to a convenience sample of 132 women attending a nurse-led clinic and 150 seen at a doctor-led clinic. RESULTS: There was a 90% response rate. The median total satisfaction scores, out of a total of five, were 4.47 and 4.30 for the nurse-led and doctor-led groups, respectively (P = 0.05). Significantly higher scores on the sub-scales measuring quality and competence of technical care (P < 0.001), provision of information (P = 0.01) and overall satisfaction (P = 0.01) were seen for the nurse-led group. No significant differences were found in the sub-scales measuring service attributes and specific attributes of interpersonal relationships. CONCLUSION: The rigorous development, piloting and testing phases of this satisfaction questionnaire led to reliable and valid results. This study demonstrated that nurse-led clinics within this service are an acceptable alternative to the existing doctor-led clinics.

Itch characteristics in Chinese patients with atopic dermatitis using a new questionnaire for the assessment of pruritus.

BACKGROUND: Although pruritus is the predominant and commonest feature of atopic dermatitis, its clinical characteristics have not been explored. OBJECTIVE: To characterize the clinical pattern and sensory and affective dimensions of the itch experience utilizing a comprehensive itch questionnaire. METHODS: A structured itch questionnaire based on the McGill pain questionnaire was given to 102 Chinese patients with known atopic dermatitis. RESULTS: There were 100 patients with atopic dermatitis who fully filled the questionnaire. In 87% of the patients pruritus appeared on a daily basis. It had a prolonged duration (mean duration 10.7 7.3 years). It involved all body areas mostly in the lower limbs (83%), flexures (76%), upper limbs (71%) and neck (65%). Itch intensity during its peak was nearly twice higher than the itch of a mosquito bite. Itching was most frequent at night (65%), and 84% of patients reported of difficulty falling asleep. Daily life activities which increased the severity of itch were sweat in 96%, dryness in 71%, stress in 71% and physical effort in 73%. The major factors which were found to reduce the intensity of pruritus included: bathing with cold water in 55% and cold ambient environment in 56%. Associated symptoms were heat sensation (51%), sweating (40%) and pain in the pruritic area (45%). The various anti-pruritic therapies had limited long-term effect. The pruritus was bothersome (52%) and a major distress to the patient. The affective score correlated to itch intensity during its peak (r = 0.4, P < 0.001). CONCLUSIONS: The study provided a detailed description of pruritus in atopic dermatitis with new data on affective and sensory dimensions and associated symptoms. The questionnaire was found to be a useful tool in characterization of itch.

Psychological characteristics of eating disorders as evidenced by the combined administration of questionnaires and two projective methods: the Tree Drawing Test (Baum Test) and the Sentence Completion Test.

The objective of this study is to examine psychological/psychopathological characteristics of eating disorders and their subtypes through a combined administration of questionnaires and projective tests. Three questionnaires (Eating Disorder Inventory - 2, Social Adaptation Scale, Southern California University Eating Disorder Inventory - Revised) and two projective tests (the Tree Drawing Test [TDT, Baum Test], and the Sentence Completion Test [SCT]) were administered to 126 female patients between the ages of 15 and 30 years, with eating disorders according to DSM-IV criteria at our outpatient clinic, and to 54 sex- and age-matched control subjects. The purging subtypes of eating disorders (anorexia nervosa - binge-eating/purging type [ANBP] and bulimia nervosa - purging type [BNP]) were clearly differentiated from the controls, both by the questionnaires and the projective tests. Compared with the controls, ANBP/BNP showed more problematic profiles across the three questionnaires, drew smaller and poorer trees in TDT to a more left location on the drawing paper, and gave fewer positive, and more negative responses in SCT. In contrast, few significant differences were found between anorexia nervosa- restricting type (ANR) and the controls, and between ANBP and BNP. As a trend, however, ANR was consistently located between the controls and ANBP/BNP across the whole questionnaires and projective tests.

Development and validation of an audit instrument: the Prostate Outcomes Questionnaire.

OBJECTIVE: To develop a short, patient-based questionnaire for auditing the outcomes of treatment for benign prostatic hyperplasia (BPH) and to evaluate the acceptability, reliability and validity of the measure. PATIENTS AND METHODS: Data from a long research questionnaire used in the Oxford/North West Thames Prostatectomy Study were analysed to identify the subset of items which contained the most scientifically sound indicators of outcome. Items were selected on the basis of standard psychometric analyses to develop a short questionnaire, the Prostate Outcomes Questionnaire (POQ), a 27-item instrument covering urinary symptoms, complications after surgery, quality of life and patient satisfaction with outcome. The POQ was field tested for acceptability, reliability and validity in a postal survey of 125 men undergoing transurethral resection of the prostate for BPH from seven hospitals in south-east England. RESULTS: The POQ was highly acceptable to patients, as indicated by a 95% response rate, the absence of 'floor' and 'ceiling' effects and a low proportion of missing data. It showed excellent internal consistency reliability (Cronbach's alpha of 0.82-0.93 for the five summary scales and a mean item-total correlation of 0.56) and test-retest reliability (test-retest correlations for items were 0.40-1.00, with a mean test-retest correlation of 0.85, and for summary scales of 0.91-0.95). Construct validity was confirmed by: high intercorrelations between the five summary scales and the total score (0.88-0.95), with a pattern of intercorrelations among specific subscales that showed item-convergent and discriminant validity; higher scores for patients who reported an improvement after surgery than in those who were not improved (P < 0.001); the expected gradient of scores for patients reporting different levels of symptom distress (P < 0.001); high correlations with the longer parent questionnaire (0.75-0.88); and low to moderate correlations with the Nottingham Health Profile and Activities of Daily Living scores (0.15-0.67), with the pattern of correlations providing evidence of scale convergent and discriminant validity. Correlations with age and social class were low, suggesting that responses were not biased by sociodemographic factors. CONCLUSION: The POQ is a practical and scientifically sound patient-based measure of outcome after treatment for BPH which can be used for routine audit. It takes < 5 min to complete, is feasible for routine monitoring of large numbers of patients by postal survey, and is accompanied by a Users' Manual which provides practical help in conducting a local patient survey, and a computer program for scoring data. Most importantly, the POQ has been shown scientifically to perform well, having met standard psychometric criteria for reliability and validity.

Cross-cultural adaptation of the Nordic musculoskeletal questionnaire.

BACKGROUND: Reports in the literature have identified a need for internationally standardized and reliable measurements to analyse musculoskeletal symptoms. Screening of musculoskeletal disorders may serve as a diagnostic tool to evaluate the work environment. The Nordic general questionnaire is a standardized instrument used to analyse musculoskeletal symptoms in an ergonomic or occupational health context. PURPOSE: To translate and adapt a version of the Nordic general questionnaire into Brazilian Portuguese and evaluate its reliability. METHOD: The cross-cultural adaptation was performed according to internationally recommended methodology, using the following guidelines: translation; back-translation; committee review; and pretesting. First, the questionnaire was independently translated into Portuguese by two teachers and one doctor, and a consensus version was generated. Second, two other translators performed a back-translation independently from one another. This version was then submitted to a committee, consisting of six specialists in the area of knowledge of the instrument, to evaluate its equivalence to the original instrument. The final version was pretested on 20 subjects randomly selected in an outpatient clinic. Reliability was assessed by a test-retest procedure at 1-day intervals using the Kappa coefficient in a group of 40 subjects. The Kappa agreement values were calculated for each one of the four questions of the questionnaire. The agreement among the same observers was substantial, varying from 0.88 to 1, according to the Kappa values. RESULTS: these demonstrated strong agreement of the instrument, suggesting that the Brazilian version of the "Standardized Nordic Questionnaire" offers substantial reliability.

Coping with illness-related problems in persons with progressive muscular diseases: the Swedish version of the Ways of Coping Questionnaire.

One of the most widely used self-assessment inventories of coping is the Ways of Coping Questionnaire. The aims of the study were to describe coping with illness-related problems in persons with muscular diseases and to investigate the influence of demographic variables. Also, the reliability of the Swedish version of the Ways of Coping Questionnaire was to be evaluated. Forty-four persons with muscular dystrophy and 32 persons with postpolio syndrome, along with a comparison group of 214 students, completed the questionnaire. The findings of this study show that there are some different coping patterns in students as compared with persons with chronic disease. The coping strategy Distancing was used more and the strategy Accepting Responsibility used less frequently in the chronic disease groups and may be an expression of the inevitable physical limitations caused by the progressiveness of muscular dystrophy and postpolio syndrome. Furthermore, persons with muscular dystrophy also used less problem-focused coping in the form of Confrontive Coping and Planful Problem Solving when compared with the postpolio and student groups. In addition, women in the three groups employed the strategy of Seeking Social Support more often than did men. Regarding the psychometric properties of the Swedish version of the Ways of Coping Questionnaire, internal consistency was acceptable for the total score, but lower and not acceptable for several of the subscales. In the student group, but not in the chronic disease groups, there were low correlations between subscales, which indicate discriminative ability. More research is necessary to further investigate the reliability and validity of the Swedish version of the Ways of Coping Questionnaire before this instrument can be used routinely to assess coping patterns in patients with chronic disease.

A screening questionnaire for body dysmorphic disorder in a cosmetic dermatologic surgery practice.

BACKGROUND: Dermatologic surgeons frequently see patients with body dysmorphic disorder, a distressing or impairing preoccupation with a nonexistent or slight defect in appearance. Recognition of this disorder is essential to avoid unnecessary and generally unsatisfying surgical outcomes, but no screening tools are available for use in a dermatology setting. OBJECTIVE: To develop and validate a brief self-report questionnaire to screen for body dysmorphic disorder in dermatology settings. METHODS: A questionnaire was developed and its sensitivity and specificity determined in 46 subjects, using a reliable clinician-administered diagnostic interview for body dysmorphic disorder. The interrater reliability of a defect severity scale was also determined (n = 50). RESULTS: The self-report questionnaire had a sensitivity of 100% and a specificity of 93%. The interrater reliability (ICC) of the defect rating scale was.88. CONCLUSIONS: This brief questionnaire was a highly effective screening tool for body dysmorphic disorder in a cosmetic dermatology setting. Use of this questionnaire may help identify patients with this syndrome.

Development and validation of the Migraine-Specific Quality of Life Questionnaire.

This paper describes the development and validation of a migraine-specific quality-of-life instrument that is capable of measuring health-related quality-of-life impairments attributed to migraine. Item selection, item reduction, and pretesting and finalization of items during the instrument development phase resulted in a total of 16 questions which were incorporated into the Migraine-Specific Quality of Life Questionnaire (Version 1:0) (1992 Glaxo Wellcome Inc). Three meaningful dimensions were hypothesized: Role Function-Restrictive, Role Function-Preventive, and Emotional Function. In the instrument validation phase, the Migraine-Specific Quality of Life Questionnaire was mailed to 1109 migraine patients, providing a response rate of 45% (n = 458). Initial psychometric evaluation of the questionnaire indicated that it possessed adequate reliability with Cronbach's alpha for the three dimensions ranging between 0.70 to 0.85. The Migraine-Specific Quality of Life Questionnaire possessed adequate content and criterion validity. All but three items satisfied the test of construct validity. In conclusion, the Migraine-Specific Quality of Life Questionnaire has acceptable psychometric properties and can be used to estimate the effect of migraine and its treatment on the patient's health-related quality of life.

Migraine therapy: development and testing of a patient preference questionnaire.

OBJECTIVES: To develop and test a patient preference questionnaire in migraine. METHODS: A user-friendly, self-administered questionnaire was developed to assess the relative importance of aspects of migraine therapy to patients. It was tested in a convenience sample of 66 migraineurs. The questionnaire has five sections: patient preference, migraine history, demographics, usual behavior during an attack, and migraine impact on cognition and functionality. It employs a special reverse-ranking technique to quantify preferences. RESULTS: Sixty-six migraineurs participated: 86% were women, 53% had not consulted their doctor about migraine in the previous year; and only 51% took prescribed medication, the majority (52%) at the start of a migraine. "A medication that can be taken any time during a migraine attack" was ranked most important by 20% of the migraineurs, one that decreases pain from the unbearable level in 30 minutes by 17%, and one that relieves pain completely within 2 hours by 15%. Not being able to think or concentrate with severe symptoms was reported by 71%. Optional activities were impeded by migraine in 83% of subjects, but required activities in only 60%. CONCLUSIONS: The patient preference questionnaire is readily completed by subjects and reveals that the dimensions of relief preferred by patients can be addressed by a self-report questionnaire.

Reproducibility and validity of the secondary level School-Based Nutrition Monitoring student questionnaire.

OBJECTIVE: To evaluate the reproducibility and validity of the School-Based Nutrition Monitoring (SBNM) secondary level student questionnaire. DESIGN: Reproducibility was evaluated using a test-retest study design by administering the questionnaire on the same day (morning and afternoon, n=254) and, when appropriate, 9 to 14 days apart (n=259). Validity was assessed by comparing foods selected on the questionnaire with foods reported from a single 24-hour recall covering the same referent period (yesterday) in 209 students. SUBJECTS/SETTING: Eighth grade students in middle schools from central Texas were used: male and female, approximately 75% white, for the reproducibility study, with 15% Hispanic, 6% African American; for the validation study, approximately 38% white, 41% Hispanic, and 17% African American. STATISTICAL ANALYSIS: Spearman rank order correlation, kappa statistic, and percentage agreement were used for both reproducibility and the validation. RESULTS: For the reproducibility study, agreement for questions about food intake "yesterday" were 70% to 98%, with kappa statistics ranging from 0.54 to 0.93 and correlations between 0.66 and 0.97. Questions on recent physical activity had high agreement (66% to 89%) as did "usual" physical activity items, weight loss, and food selection behaviors. Nutrition knowledge items showed relatively weaker reliability: agreements ranged from 47% to 92%, with kappa statistics between 0.30 and 0.56. Attitude questions had weaker agreement (50% to 87%), kappa statistics (0.27 to 0.52), and correlations (0.33 to 0.63). For the validation study, correlation coefficients ranged from 0.32 for breads to 0.68 for milk and beans. Percentage agreement ranged from 38% for breads to 89% for gravy. APPLICATIONS/CONCLUSIONS: Most questions on the SBNM secondary questionnaire were found to have acceptable reproducibility, whereas validation of food choice behaviors showed results similar to or better than other dietary assessment instruments for this age group. This questionnaire is a useful epidemiologic tool for surveillance, assessing broad intervention effects among groups or providing needs assessment data on selected nutrition and physical activity-related constructs.

Evaluation of the construct validity of the DASH questionnaire by correlation to the SF-36.

The construct validity of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire was evaluated by examining its correlation to the Medical Outcomes Study Short Form-36 (SF-36). The study sample was 90 patients seen at the upper-extremity clinic of a university-based orthopedic practice. Patients were asked to complete a packet that included the DASH and SF-36 questionnaires. Pearson correlation coefficients of the DASH questionnaire to the SF-36 subscales ranged from -0.36 to -0.62. The DASH questionnaire had fewer ceiling and floor scores than most of the SF-36 subscales. These results support the DASH questionnaire as a valid measure of health status useful in patients with a wide variety of upper-extremity complaints.

Comparative responsiveness of the disabilities of the arm, shoulder, and hand, the carpal tunnel questionnaire, and the SF-36 to clinical change after carpal tunnel release.

PURPOSE: The objective of this study was to compare the responsiveness (ability to accurately detect change) of 3 self-administered questionnaires to changes produced by carpal tunnel release. METHOD: The Disabilities of the Arm, Shoulder and Hand (DASH), the Brigham and Women's Carpal Tunnel Questionnaire, and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were completed by 34 subjects before surgery and at 6 and 12 weeks after carpal tunnel release. RESULTS: The instrument most sensitive to clinical change at 12 weeks as judged by effect size and standardized response means was the Carpal Tunnel Questionnaire (effect size/standardized response means, 1.71/1.66) followed by the DASH (1.01/1.13) and the Medical Outcomes Study 36-Item Short-Form Health Survey bodily pain (0.57/0.52) and role physical (0.39/0.39) subscales. There was good correlation between DASH and Carpal Tunnel Questionnaire change scores (Spearman correlation coefficient 0.87). CONCLUSIONS: The Carpal Tunnel Questionnaire is the most sensitive to clinical change, but the DASH is sufficiently responsive for use in outcome studies of carpal tunnel syndrome done 12 or more weeks after surgery.

[Using the Lequesne questionnaires for patients with hip and knee disabilities in daily routine to reflect the quality of outcome in rehabilitation].

AIM: Studies in rehabilitation research put great value on patients' self-assessment. Patients with hip or knee diseases who need an orthopaedic rehabilitation suffer mainly pain, reduction of walking distance and other disabilities that impact on the activities of daily life. The Lequesne scores for the hip and knee are an indicator to show the degree of disabilities. The aim of the study was to prove that the Lequesne indices are reliable instruments for the individual to express the outcome of rehabilitation. We tested the Lequesne indices in daily clinical work, in the handling and in the acceptance. METHOD: Since May 1999 the rehabilitation center Bad Eilsen uses the Lequesne questionnaires as self-report questionnaire instruments for patients with hip and knee disabilities. 145 patients with hip and 122 patients with knee diseases filled in the questionnaires correctly and handed them back. RESULTS: The Lequesne indices are able to show developments in both directions; improvement as well as change for the worse. The Lequesne questionnaires are helpful to complete the common clinical parameters. CONCLUSION: Using the Lequesne questionnaires as a self-report instrument in our daily routine we are able to obtain a good reflection of individual health condition and the quality of outcome in rehabilitation.

[Motivation for psychosomatic-psychotherapeutic treatment of vocational stresses -- development and validation of a questionnaire].

BACKGROUND: There is a lack of questionnaires assessing the motivation of inpatients to scrutinize occupational stresses and deal with them as part of their psychotherapeutic treatment. Work-related stress contributes significantly to the development of mental disorders. Vocational reintegration is an outcome criterion for the success of vocational rehabilitation. Patients are often not motivated for dealing with occupational stresses during inpatient medical rehabilitation. Therefore it is necessary to assess patient motivation at the beginning of treatment, in order to assign them to specific interventions, e. g. promoting motivation. METHOD: A questionnaire (Fragebogen zur berufsbezogenen Therapiemotivation -- FBTM) consisting of 84 items was developed, based on published questionnaires for psychotherapy motivation. 283 psychosomatic rehabilitation inpatients were administered the FBTM, subsequently analyzed by item and factor analyses. Based on a second sample (n = 282) confirmatory factor analyses and validation of the questionnaire were executed. RESULTS: Item and factor analyses revealed a four factor structure. 24 items constituted the subscales that could be described as "intention to change", "wish for pension", "negative treatment expectations" and "active coping". Reliability (Cronbach's Alpha) was satisfactory with coefficients between 0.69 and 0.87, and only low correlations could be found between the four subscales. Correlations with other measures were most pronounced for the subscale "intention to change". Some significant but low correlations could be reported between the FBTM and a standardized questionnaire of psychotherapy motivation (FMP). Confirmatory factor analyses of a second sample (n = 282) confirmed the original four factors. First evidence of sensitivity could be observed in a sample of patients who took part in an intervention promoting work-related therapy motivation during psychosomatic inpatient rehabilitation. CONCLUSIONS: The FBTM is a reliable and valid instrument assessing work-related therapy motivation of inpatients, as a relevant therapeutic measure in psychosomatic rehabilitation. Further validation, especially the analysis of predictive validity is desirable.

[Evaluating the patient satisfaction questionnaire after inpatient treatment in phoniatrics and pediatric audiology--a contribution to quality control?].

PURPOSE: In Germany public hospitals are compelled to evaluate patient satisfaction with their treatment as a part of quality management. The purpose of this study was to assess by means of a short questionnaire inpatient satisfaction with medical care in a phoniatric-paedaudiologic department. MATERIALS AND METHODS: From April 1995 until March 1997, 638 patients underwent inpatient treatment for phoniatric or paedaudiologic diseases in our department. A confidential questionnaire was handed out to the patients or to accompanying parents. 13 questions covered different aspects of hospital treatment, such as satisfaction with diagnostic and therapeutic measures, nursing care, accommodation, catering and administration. The participants were asked to rate on a scale of 1 (very good) to 6 (very poor). RESULTS: 306 (48%) of the patients returned their questionnaires. 16% of them expressed substantial dissatisfaction both with administration and accommodation. Only 2.7% of the patients conveyed a poor overall impression of their inpatient treatment. 3% asserted they would not want to be treated in the department again as the inpatient. However, the mean overall assessment indicated a high degree of patient satisfaction. CONCLUSIONS: Although the self-explaining 13-item questionnaire is easy to evaluate at low cost, it appears to be an inadequate measuring device for routine assessment of inpatient satisfaction since only 48% of the questionnaires could be analysed.

Comparison of patient questionnaires, medical records, and plasma assays in assessing exposure to benzodiazepines in elderly subjects.

OBJECTIVE: Exposure in pharmacoepidemiologic studies can rely on various sources such as medical records, patient questionnaires, or plasma samples, which do not always concur. This study endeavored to compare sources of information on current exposure to benzodiazepines in elderly subjects. METHODS: In a study in a hospital admissions department, 1136 elderly subjects included in a case-control study each completed a structured questionnaire. In addition, an inspection of the medical records of each subject was performed, as well as screening of a plasma sample (high-pressure liquid chromatography--diode array detector) for current exposure to benzodiazepines. RESULTS: Benzodiazepines were found in the plasma of 33% of 1013 patients, in the records of 31% of patients, and in the questionnaires of 36% of 797 respondents. With use of the plasma results as a standard, questionnaires had 11% false positives and 28% false negatives; medical records had 14% false positives and 23% false negatives. The kappa for concordance between questionnaires and records was 0.63. Most of the errors were related to the unexpected presence in plasma of clorazepate, commonly used as a hypnotic agent. CONCLUSIONS: Patient recall and medical records are not reliable measures of current exposure to benzodiazepines in elderly persons, although this unreliability may be more marked with certain drugs used as hypnotic agents.

PrimeScreen, a brief dietary screening tool: reproducibility and comparability with both a longer food frequency questionnaire and biomarkers.

OBJECTIVE: Diet is an important determinant of health outcomes, but physicians have few ways to identify persons with suboptimal diets. The purposes of this study were to examine the reproducibility of a short dietary assessment questionnaire (PrimeScreen) and to compare its results with those of a longer food frequency questionnaire and with plasma levels of selected nutrients. DESIGN: Each subject completed two PrimeScreen questionnaires at an interval of 2 weeks and one full length, 131-item, semiquantitative food frequency questionnaire (SFFQ), and had a sample of blood drawn. We compared the PrimeScreen with two reference standards, the SFFQ and plasma levels of selected nutrients. SETTING: A large managed care organization in New England. SUBJECTS: A total of 160 men and women, aged 19-65 years, participated. RESULTS: For foods and food groups, the mean correlation coefficient (r) was 0.70 for reproducibility and 0.61 for comparability with the SFFQ. For nutrients, the mean r was 0.74 for reproducibility and 0.60 for comparability with the SFFQ. No substantial differences were evident by sex, race, body mass index, occupation or education. Correlation coefficients for the comparison of vitamin E, beta-carotene and lutein/zeaxanthin intakes from the PrimeScreen with plasma levels were 0.33, 0.43 and 0.43, respectively. These values were similar to those comparing the SFFQ with plasma levels. The median time to complete PrimeScreen was 5 min; 87% of participants required fewer than 10 min. CONCLUSIONS: A quick way to assess quality of diet among adults, PrimeScreen has adequate reproducibility and its results compare well with a longer food frequency questionnaire and biomarkers.
