Validation and application of an instrument for measuring patient relatives' perception of quality of geriatric care.

OBJECTIVE: To test and validate a questionnaire concerning patient relatives' perception of the quality of geriatric care. DESIGN: Three anonymous questionnaire studies. SETTINGS: A community-based geriatric care organization and a university hospital in Sweden. STUDY PARTICIPANTS: Three hundred and eighteen relatives of patients within the geriatric care organization and 38 relatives of patients at the university hospital. MAIN OUTCOME MEASURES: A questionnaire composed of eight quality of care indices and an overall quality rating. Reliability and validity estimates were compared between the results from the three surveys. RESULTS: Internal reliability estimates for all indices were >0.65 and consistent over time. Inter-index correlations were >0.60 between certain indices, indicating some overlap. Second order factor analysis resulted in three distinct index groupings: personnel, relative's role, and care content. These three dimensions summarize relatives' perceptions of the quality of geriatric care. CONCLUSIONS: There is a need for a confidential patient relatives' questionnaire in geriatric care. The results revealed good questionnaire reliability and validity. The questionnaire needs to be tested in larger, independent samples in order to validate the indices further.     

Development and validation of a questionnaire measuring hospital consumer satisfaction

This study describes the process of development of a new instrument for measuring patient satisfaction with hospital care in Italy. The self-administered questionnaire included a total of 48 items, -contributing to the construction of 8 scales, each of them describing a specific area of interest such as medical care and nursing, several aspects of organisation, comfort and overall outcome of care. Psychometric characteristics of the questionnaire were in terms of acceptability, validity, reliability and the ability to discriminate different levels of satisfaction in various patient groups. Psychometric analyses resulted in a convincing construct validity and reliability, as described by the Cronbach Alpha coefficient estimates [range 0.73-0.95]. The high compliance obtained (67.3%) can be considered a sign of good acceptability of the questionnaire and of its mode of administration. These analyses demonstrate a good performance of the questionnaire in terms of both validity and reliability, suggesting that this instrument can represent a solid base for future applications.     

Measuring job satisfaction in residential aged care.

BACKGROUND: Staff satisfaction has received increasing recognition as an important factor influencing service quality and in particular the quality of residents' lives in residential aged care facilities, where staff typically have a long-term and close relationship with residents. Consequently, a valid and reliable instrument is required to assess staff satisfaction in this particular context. OBJECTIVE: This paper aims to assess the factor structure, reliability, and validity of the Measure of Job Satisfaction (MJS) instrument when used in residential aged care facilities. DESIGN: A cross-sectional survey design was used to collect the required information, and a stratified random sampling method was utilized to select facilities. Exploratory and confirmatory factor analyses were conducted to assess the factor structure of staff satisfaction via the MJS. SETTING: Both high and low care residential aged care facilities in Western Australia. STUDY PARTICIPANTS: Nine hundred and eighty-three staff (including the Director of Nursing, manager, registered nurses, enrolled nurses, nursing assistants, and therapists) in 70 residential aged care facilities. RESULTS: An acceptable five-factor (22-item) measurement model was derived. The Cronbach's alpha reliability levels range from 0.86 to 0.95. Convergent and discriminant validity are also satisfactory. CONCLUSION: This investigation has confirmed that a modified MJS is a reliable and valid instrument for assessing staff satisfaction in residential aged care settings.     

User satisfaction is influenced by the interval between a health care service and the assessment of the service

In order to improve the quality of patient care, questionnaires are often used to identify user’s experiences and evaluations, but only a few studies have examined whether measuring user satisfaction at different time points influences the assessment of health care. Several studies have shown equivalency between paper and electronic patient reported outcomes; however, none of these studies have considered the fact that electronic questionnaires are usually completed at the hospital, while paper questionnaires are typically completed at home weeks after the visit. In order to ensure that the comparison of results collected by the two different methods are not biased, the aim of this study was to determine if the interval between an outpatient visit and the assessment of the quality of care influences user satisfaction and to compare response rates between questionnaires completed at different times. In a follow-up study, parents from a paediatric outpatient clinic in Denmark were quasi-randomised to 1 of 3 groups: group 1 completed an electronic questionnaire on a touch screen computer in the outpatient clinic and a paper questionnaire 3–6 weeks after the visit; group 2 completed a paper questionnaire in the outpatient clinic and a paper questionnaire 3–6 weeks after the visit; and group 3 completed a paper questionnaire 3–6 weeks after the visit. A total of 1148 parents completed at least 1 questionnaire. User satisfaction was significantly lower when the assessment was made after a visit to the outpatient clinic compared to an assessment made at the clinic. The response rates of questionnaires completed at the clinic were significantly higher than the response rates of questionnaires completed after the visit. Both the timing of surveys and response rates need to be taken into consideration when planning user surveys. Outcomes from surveys conducted at different times are not readily comparable.     

Development and psychometric testing of a novel food service satisfaction questionnaire for food service staff of aged care homes

Background

Food service staff are integral to delivery of quality food in aged care homes yet measurement of their satisfaction is unable to be performed due to an absence of a valid and reliable questionnaire. The aim of this study was to develop and perform psychometric testing for a new Food Service Satisfaction Questionnaire developed in Australia specifically for use by food service staff working in residential aged care homes (Flinders FSSQFSAC).

Methods

A mixed methods design utilizing both a qualitative (in-depth interviews, focus groups) and a quantitative approach (cross sectional survey) was used. Content validity was determined from focus groups and interviews with food service staff currently working in aged care homes, related questionnaires from the literature and consultation with an expert panel. The questionnaire was tested for construct validity and internal consistency using data from food service staff currently working in aged care homes that responded to an electronic invitation circulated to Australian aged care homes using a national database of email addresses. Construct validity was tested via principle components analysis and internal consistency through Cronbach’s alpha. Temporal stability of the questionnaire was determined from food service staff undertaking the Flinders FSSQFSAC on two occasions, two weeks apart, and analysed using Pearson’s correlations.

Results

Content validity for the Flinders FSSQFSAC was established from a panel of experts and stakeholders. Principle components analysis revealed food service staff satisfaction was represented by 61-items divided into eight domains: job satisfaction (α=0.832), food quality (α=0.871), staff training (α=0.922), consultation (α=0.840), eating environment (α=0.777), reliability (α=0.695), family expectations (α=0.781) and resident relationships (α=0.429), establishing construct validity in all domains, and internal consistency in all (α>0.5) except for “resident relationships” (α=0.429). Test-retest reliability coefficients ranged from 0.276 to 0.826 dependent on domain, with test-retest reliability established in seven domains at r>0.4; an exception was “reliability” at r=0.276.

Conclusions

The newly developed Flinders FSSQFSAC has acceptable validity and reliability and thereby the potential to measure satisfaction of food service staff working in residential aged care homes, identify areas for strategic change, measure improvements and in turn, improve the satisfaction and quality of life of both food service staff and residents of aged care homes.

     

Questionnaire to assess patient satisfaction with pharmaceutical care in Spanish language.

OBJECTIVE: To develop and validate a questionnaire, in Spanish, for assessing patient satisfaction with pharmaceutical care received in community pharmacies. DESIGN: Selection and translation of questionnaire's items; definition of response scale and demographic questions. Evaluation of face and content validity, feasibility, factor structure, reliability and construct validity. SETTING: Forty-one community pharmacies of the province of Santa Fe. Argentina. PARTICIPANTS: Questionnaire administered to patients receiving pharmaceutical care or traditional pharmacy services. MAIN OUTCOME MEASURE: Pilot test to assess feasibility. Factor analysis used principal components and varimax rotation. Reliability established using internal consistency with Cronbach's alpha. Construct validity determined with extreme group method. RESULTS: A self-administered questionnaire with 27 items, 5-point Likert response scale and demographic questions was designed considering multidimensional structure of patient satisfaction. Questionnaire evaluates cumulative experience of patients with comprehensive pharmaceutical care practice in community pharmacies. Two hundred and seventy-four complete questionnaires were obtained. Factor analysis resulted in three factors: Managing therapy, Interpersonal relationship and General satisfaction, with a cumulative variance of 62.51%. Cronbach's alpha for the whole questionnaire was 0.96, and 0.95, 0.88 and 0.76 for the three factors, respectively. Mann-Whitney test for construct validity did not showed significant differences between pharmacies that provide pharmaceutical care and those that do not, however, 23 items showed significant differences between the two groups of pharmacies. CONCLUSION: The questionnaire developed can be a reliable and valid instrument to assess patient satisfaction with pharmaceutical care in community pharmacies in Spanish. Further research is needed to deepen the validation process.     

Newcastle satisfaction with nursing scales: an instrument for quality assessments of nursing care.

OBJECTIVES--To test the validity and reliability of scales for measuring patients' experiences of and satisfaction with nursing care; to test the ability of the scales to detect differences between hospitals and wards; and to investigate whether place of completion, hospital, or home influences response. DESIGN--Sample survey. SETTING--20 wards in five hospitals in the north east of England. PATIENTS--2078 patients in general medical and surgical wards. MAIN MEASURES-- Experiences of and satisfaction with nursing care. RESULTS--75% of patients approached to complete the questionnaires did so. Construct validity and internal consistency were both satisfactory. Both the experience and satisfaction scales were found to detect differences between randomly selected wards and hospitals. A sample of patients (102) were sent a further questionnaire to complete at home. 73% returned this; no significant differences were found in either experience or satisfaction scores between questionnaires given in hospital or at home. CONCLUSION--Scales to measure patients' experiences of and satisfaction with nursing in acute care have been developed and found to be valid, reliable, and able to detect differences between hospitals and wards. Questionnaires can be given before patients leave hospital or at home without affecting scores, but those given at home have a lower response rate.     

Developing and validating a novel staff questionnaire to identify barriers and enablers to nutrition and mealtime care on hospital wards

Aims

Improving hospital nutrition and mealtime care is complex and often requires multifaceted interventions and implementation strategies to change how staff, wards and systems operate. This study aimed to develop and validate a staff questionnaire to identify multilevel barriers and enablers to optimal nutrition and mealtime care on hospital wards, to inform and evaluate local quality improvement.

Methods

Literature review, multidisciplinary focus groups and end-user testing informed questionnaire development and establishment of content and face validity. To determine the construct validity, the questionnaire was administered to ward staff working in five wards across two facilities (acute hospital, rehabilitation unit). Exploratory factor analysis was used to estimate the number of factors and to guide decisions about whether to retain or reject individual items. Scale reliability was assessed using Cronbach's alpha.

Results

The questionnaire was completed by 138 staff, with most respondents being nurses (57%) and working in the acute care facility (76%). Exploratory factor analysis supported construct validity of four of the original seven subscales. The final questionnaire consisted of 17 items and 4 sub sub-scales related to (1) Personal Staff Role; (2) Food Service; (3) Organisational Support, and (4) Family Involvement; each sub-scale demonstrated good reliability with Cronbach's alpha values all >0.70.

Conclusion

This novel and brief questionnaire shows good reliability and preliminary evidence of construct validity in this small sample. It provides a potentially useful instrument to identify barriers and enablers to nutrition and mealtime care from the staff perspective and inform where improvement efforts should be focused.     

The quality of health care and patient satisfaction: an exploratory investigation of the 5Qs model at some Egyptian and Jordanian medical clinics

PURPOSE: To examine the major factors affecting patients' perception of cumulative satisfaction and to address the question whether patients in Egypt and Jordan evaluate quality of health care similarly or differently. DESIGN/METHODOLOGY/APPROACH: A conceptual model including behavioural dimensions of patient-physician relationships and patient satisfaction has been developed. As the empirical research setting, this study concerns three hospitals in Egypt and Jordan. The survey instrument in a questionnaire form was designed to achieve the research objectives. A total of 48 items (attributes) of the newly developed five quality dimensions were identified to be the most relevant. A total of 224 complete and usable questionnaires were received from the in-patients. FINDINGS: Hospital C has above-average total and dimensional qualities and patients are the most satisfied in accordance with all dimensions of services. Hospitals A and B have under-average total qualities as the majority of patients are not satisfied with services. Comparing hospitals A and B, in the majority of dimensions (with the exception of Q5), the quality in hospital B is higher than in hospital A. Patients' satisfaction with different service quality dimensions is correlated with their willingness to recommend the hospital to others. A cure to improve the quality for health-care services can be an application of total relationship management and the 5Qs model together with customer orientation strategy. PRACTICAL IMPLICATIONS: The result can be used by the hospitals to reengineer and redesign creatively their quality management processes and the future direction of their more effective health-care quality strategies. ORIGINALITY/VALUE: In this research a study is described involving a new instrument and a new method which assure a reasonable level of relevance, validity and reliability, while being explicitly change-oriented. This study argues that a patient's satisfaction is a cumulative construct, summing satisfaction with five different qualities (5Qs) of the hospital: quality of object, processes, infrastructure, interaction, and atmosphere.     

Relationships with the medical staff and aspects of satisfaction with care expressed by parents of children with cancer

Seventy-four parents of children with cancer were asked to characterize the behavior of medical staff members with whom they interacted. Seven empirically distinct dimensions of staff behavior relevant to their relationships with parents were identified, including information transmission, clarity and honesty of communication, acceptance of parental efficacy, resolution of conflicts, personal contact with parents, empathy with the child, and staff competence. With respect to their experiences with the treatment of their child, parents also were asked to indicate their satisfaction with the medical staff in terms of changes in their respect and/or anger for the medical staff, changes in feelings about doctors, support received from doctors and nurses, and stress resulting from tense relations with the staff. The seven dimensions of parent-staff relationships were used as predictors in a series of multiple regressions employing these satisfaction measures as criteria. The overall quality of the parent-staff relationship was best predicted by positive personal contact. The strongest predictor of whether or not parents felt increased anger was staff empathy with child. Increased respect for the medical staff was predicted by a combination of information transmission and perception of staff competence. Experience of support by parents was best predicted by information transmission and staff acceptance of parental efficacy in treatment and decision making. This complex pattern supports the usefulness of disaggregating measures of staff behavior and parent satisfaction when examining the relations between medical consumers and service providers.The data were gathered with the participation and support of a major university medical center and children's hospital, and a parent self-help organization, SHARE: Families of Children with Cancer. This report, and the larger study, is part of an action-research effort conducted jointly by SHARE, the hospital staff, and the investigators.     

Construction of a scale measuring inpatients' opinion on quality of care.

OBJECTIVE: To develop a reliable and valid measure of patient opinions on quality of hospital care. DESIGN: Issues of importance to patients and possible scale items were generated by literature review and non-structured interviews of patients, former patients, health care providers and researchers. Semi-structured interviews with inpatients and pilot studies were conducted to modify or remove ambiguous questions and reduce skewed responses. A study was then made to select from these questions relevant items and variables correlated to patient evaluation of quality of care. A principal-components analysis was performed to select items and assess construct validity. Cronbach's alpha coefficients were calculated to estimate the reliability of the scale. Time reliability and concurrent validity were also considered. SETTING: An 800-bed French short-stay teaching hospital in Paris. STUDY PARTICIPANTS: Five-hundred and thirty-four consecutive patients hospitalized in eight medical and surgical wards. RESULTS: A 26-item scale was developed. Component analysis indicated two subscales: 'medical information' and 'relationship with staff and daily routine'. Levels of reliability were satisfactory: Cronbach's alpha coefficient exceeded 0.87 for overall scale and subscales. Concurrent validity and time reliability were also satisfactory. Multivariate analysis showed that, taking into account patients and hospitalization characteristics linked to scores (age, health status, number of hospitalizations, comorbidity, time since diagnosis, admission pattern, private patient and difficulties reported by staff), these scores differed among departments. CONCLUSION: A reliable, valid measure of inpatients' opinions on quality of care has been developed in a French hospital and variables that have to be taken into account to compare hospital departments have been selected. Items selected in the scale emphasized the importance that patients give to receiving medical information.     

Assessment of working conditions in health care workers

OBJECTIVE: Validation and first use of a self-completed questionnaire to assess opinion on working conditions in health professionals. METHODS: The questionnaire consisted of 40 items. It was developed via review of the literature and two focus groups. A reliability test-retest study was performed on 45 health professionals with different roles. Factorial validity and internal consistency of each derived subscale were evaluated on a wide sample of 514 professionals. In addition, the opinion of the health care professionals was evaluated and possible relationships were tested between total and subscale scores and the following variables: age, sex, professional role and years in the job. RESULTS: Weighted kappa was higher than 0.60 for 95% of the items, higher than 0.70 for 43% and higher than 0.80 for 20%. Factor analysis revealed that six factors--work content and organisation, physical fatigue, relationships, mental stress, hours of work, and physical environment--explained 57% of total variance. Cronbach's alpha coefficient of the subscales ranged from 0.70 to 0.91. Low levels of satisfaction in dfferent job aspects were found among general hospital staff. They were particularly dissatisfied with personal growth and development, fairness in incentives, dissemination of information, environment, support of new ideas and skills, career opportunities. In particular, satisfaction differed among the various professional roles. DISCUSSION: The questionnaire was found reliable and had a coherent factor structure, with six factors or subscales that showed good internal consistency. This questionnaire may be useful to assess satisfaction with work in health care staff. The preliminary results of its use suggest that satisfaction with different aspects of work is low.     

Development of a French inpatient satisfaction questionnaire.

OBJECTIVE: To develop a brief French-language, generic, self-administered questionnaire to measure inpatient satisfaction. DESIGN: Issues relevant to patients were identified using three open-ended questions designed in accordance with the disconfirmation paradigm. The content of patients' responses was analysed and then supplemented by items taken from published instruments in order to generate a pool of 93 items. Twenty-nine items were selected following a strict procedure. Content validity was judged by comparing the questionnaire to existing instruments. Construct validity was supported by testing specific hypotheses derived from the literature and by performing principal component analysis. Reliability was estimated by calculating Cronbach's alpha. SETTING: A 2200-bed French teaching hospital. SUBJECTS: A mail survey was carried out on a random sample of 1000 inpatients within 2-4 weeks of discharge. Eligible subjects were medical, surgical and obstetrics inpatients who had stayed in the hospital for more than 24 hours. RESULTS: The participation rate (71%) and the completion rate (95%) were indicators of acceptability. There were modest differences between the questionnaire and published instruments (financial aspects, amenities). Construct representation by principal component analysis consisted of six scales which accounted for 58% of the variance in total satisfaction scores. The reliability estimates of internal consistency ranged from 0.67 to 0.86. CONCLUSION: We propose that the self-administered multidimensional inpatient satisfaction questionnaire provided encouraging preliminary psychometric information. This instrument is intended to involve patient feedback in a continuous quality health care improvement strategy.     

The development and piloting of an instrument to measure care staff attitudes towards child self-harm

Abstract

Child self-harm has been identified as an important issue within paediatric care, but the attitudes of care staff towards the topic have received limited investigation. The aim of this paper is the justification and development of an instrument to measure care staff attitudes towards child self-harm. By identifying the salient features of the phenomenon and incorporating them into a means of data collection, it is hoped that a more realistic picture of the clinical environment emerges. The main elements of the instrument are introduced in turn and its initial piloting is described. A questionnaire was developed based on a series of hypothetical case vignettes and subjected to a number of tests. The results of the pilot test indicated that the instrument shows high levels of reliability and would therefore prove useful in eliciting staff attitudes.     

A comparison of methods for measuring patient satisfaction with consultations in primary care

BACKGROUND: Attention needs to be paid to comparing and standardizing methodsfor measuring patient satisfaction with consultations in primarycare. OBJECTIVES: To compare the Medical Interview Satisfaction Scale (MISS) andthe Consultation Satisfaction Questionnaire (CSQ) in terms ofacceptability, distribution of responses, reliability and gatherevidence of validity. In addition, to compare the scores ofpatients completing the questionnaires immediately after theconsultation in the general practitioners' surgeries with thosecompleting the questionnaires later at home. METHODS: The two questionnaires were bound as a single instrument withorder determined at random. This was given to patients immediatelyafter their consultations in eight practices in South Glamorgan. RESULTS: One hundred and ninety-eight of 316 (63%) patients completedand returned questionnaires. The distributions of patient satisfactionscores for the two questionnaires were very similar. For theMISS: mean 76.7% (SD 11.4); for the CSQ mean 77.2% (SD 12.6).Correlations between sub-scales ranged from 0.58–0.84for the MISS and from 0.40–0.79 for the CSQ. The correlationbetween the overall scales was 0.82. Levels of reliability forthe scales and sub-scales were fair to good ranging from 0.78-0.96for the MISS and from 0.73–0.94 for the CSQ. CONCLUSIONS: The study does not identify one scale as being superior in pyschometricterms, however by demonstrating consistency of responses itprovides support for the scales as measures of patient satisfactionfor use in primary care. The level of inter-correlation suggeststhat the sub-scales may not be clearly independent of each otherand suggests that total scores may be preferred. Lower levelsof satisfaction are expressed if patients complete questionnairesat home rather than in general practitioners' surgeries. Keywords. Satisfaction, primary care, psychometric testing.     

Perception and use of the results of patient satisfaction surveys by care providers in a French teaching hospital.

OBJECTIVE: . The aim of this study was to assess clinical staff's opinions on the results of in-patient satisfaction surveys and their use within the quality improvement process. SETTING: The institution is a 2200-bed teaching hospital of tertiary health care employing 8000 professionals. Patient satisfaction surveys are carried out each year using a validated questionnaire mailed to a random sample of patients. The specific results of each department are sent to the medical and paramedical managers. METHODS: We conducted a questionnaire survey on 500 care providers randomly selected in every medical and surgical department. RESULTS: A total of 261 questionnaires were returned and analysed. Overall, 94% of responders had a favourable opinion of the patient satisfaction surveys. They considered that the patient was able to judge hospital service quality, especially in its relational, organizational, and environmental dimensions. The specific results for the department were less well known than the overall hospital results (60 versus 76%). These results were formally discussed in the department according to 40% of responders; 40% declared that these data resulted in improvement actions and considered that they led to modifications in their behaviour with patients. CONCLUSIONS: Despite a declared interest in satisfaction surveys, the results remain underused by hospital staff and insufficiently discussed within teams.     

Consumer evaluation of hospital foodservice quality: an empirical investigation

PURPOSE: The purpose of this article is to estimate the relationship between acute care consumers' satisfaction with hospital foodservices, foodservice characteristics, demographic and contextual variables. DDESIGN/METHODOLOGY/APPROACH: The acute care hospital foodservice patient satisfaction questionnaire was administered to 2347 patients in Queensland, Australia from 1996-2001. Regression analysis was conducted to measure the influence of 21 foodservice attributes and seven contextual/demographic items on overall foodservice satisfaction. FFINDINGS: Foodservice satisfaction was strongly associated with variety, flavour, meat texture, temperature, meal taste, and menu staff (p < 0.01). Consumers aged 70 years or more rated their overall satisfaction significantly lower than younger consumers (p < 0.01), but no statistically significant differences in overall ratings existed for other contextual or demographic groups. RESEARCH LIMITATIONS/IMPLICATIONS: This new foodservice instrument and the methods of analysis may be generalisable, but application is likely to be context-specific. Further applications of the instrument are required to produce greater confidence in its validity and reliability across different foodservice settings. PRACTICAL IMPLICATIONS: Global statements often used in health service satisfaction surveys (e.g. a single rating of "food quality") provide insufficient information to allow managers to adapt foodservices to suit consumers' preferences. ORIGINALITY/VALUE: Detailed information of the kind produced here is required for the formulation of managerial and sectoral policies to improve the quality of health and consumer nutrition care. The findings are noteworthy and, as far as the literature review showed, no previously published study has produced this level of detail on consumer preferences across foodservice attributes or their relationship to overall foodservice satisfaction.     

Development and validation of a core outcome measure for palliative care: the palliative care outcome scale. Palliative Care Core Audit Project Advisory Group.

OBJECTIVES: To develop an outcome measure for patients with advanced cancer and their families which would cover more than either physical symptoms or quality of life related questions. To validate the measure in various specialist and non-specialist palliative care settings throughout the UK. DESIGN: A systematic literature review of measures appropriate for use in palliative care settings was conducted. In conjunction with a multidisciplinary project advisory group, questions were chosen for inclusion into the scale based on whether they measured aspects of physical, psychological, or spiritual domains pertinent to palliative care, and whether similar items had shown to be valid as part of another measure. A staff completed version was developed to facilitate data collection on all patients throughout their care, and a patient completed version was designed to enable the patient to contribute to the assessment of their outcomes when possible. A full validation study was conducted to evaluate construct validity, internal consistency, responsiveness to change over time, and test-retest reliability. Assessments were timed. SETTING: Eight centres in England and Scotland providing palliative care, including inpatient care, outpatient care, day care, home care, and primary care. PATIENTS: A total of 450 patients entered care during the study period. Staff collected data routinely on patients in care long enough to be assessed (n = 337). Of these, 262 were eligible for patient participation; 148 (33%) went on to complete a questionnaire. MAIN MEASURES: The Palliative Care Outcome Scale (POS), the European Organisation for Research on Cancer Treatment, and the Support Team Assessment Schedule. RESULTS: The POS consists of two almost identical measures, one of which is completed by staff, the other by patients. Agreement between staff and patient ratings was found to be acceptable for eight out of 10 items at the first assessment. The measure demonstrated construct validity (Spearman rho = 0.43 to 0.80). Test/re-test reliability was acceptable for seven items. Internal consistency was good (Cronbach's alpha = 0.65 (patients), 0.70 (staff)). Change over time was shown, but did not reach statistical significance. The questionnaire did not take more than 10 minutes to complete by staff or patients. CONCLUSION: The POS has acceptable validity and reliability. It can be used to assess prospectively palliative care for patients with advanced cancer.     

Evaluating family-centred service in paediatric oncology with the measure of processes of care (MPOC-20)

Background   In order to evaluate the family-centeredness of paediatric oncology services, a psychometrically sound measure of family-centred services is needed. We performed a comprehensive evaluation of the psychometric properties of the 20-item Measure of Processes of Care (MPOC-20) in parents of children undergoing treatment for cancer at five paediatric oncology centres in Canada.
Methods   The sample included 411 parents (80% response rate). Exploratory factor analysis was used to determine the best way to group the items into scales. Psychometric tests were used to examine data quality, targeting, internal consistency reliability, within-scale construct validity and known-groups validity.
Results   Exploratory factor analysis identified two factors: a summary measure of family-centred services and a scale measuring activities that meet parents' general informational needs. Scores spanned the entire scale range, floor and ceiling effects were low, and the sample distribution was not unduly skewed. Scales showed acceptable internal consistency reliability (Cronbach's alphas ≥0.93). Known-group hypotheses supported the scales' ability to differentiate between groups hypothesized to differ. Moderate effect sizes were found when MPOC-20 scale scores for parents and for children with good quality of life were compared with those with poor quality of life.
Conclusions   The MPOC-20 is the only evaluated instrument currently available to measure family-centred services in paediatric oncology. Paediatric cancer programmes can now use this tool to determine parental perception of the extent to which services are family-centred.     

Development of a soy food frequency questionnaire to estimate isoflavone consumption in US adults.

OBJECTIVE: To develop a dietary assessment instrument to measure soy food consumption and isoflavone intake and test it for reliability. DESIGN: A soy food frequency questionnaire, designed for use in this study, was administered twice to participants, separated by a 2-week interval. The questionnaire was tested for reproducibility of estimates of soy food consumption and isoflavone (genistein and daidzein) intake. SUBJECTS/SETTING: A convenience sample of 51 faculty, staff, and students was recruited from a naturopathic university. STATISTICAL ANALYSES PERFORMED: Intraclass correlation coefficients were used to assess reproducibility of estimates of soy food intake and genistein and daidzein intake. RESULTS: Correlation coefficients comparing mean soy food servings per month between the 2 administrations of the questionnaire ranged from 0.50 for soy yogurt to 0.89 for tempeh. Correlation coefficients for genistein and daidzein intake estimated by the 2 administrations of the questionnaire were the same: 0.89. Mean intake (+/- standard deviation) of genistein and daidzein was 7 +/- 10 and 4 +/- 6 mg/day, respectively. Fifteen soy foods contributed 95% of the total genistein and daidzein intake: tofu, soy yogurt, tempeh, soy milk, low-fat tofu, soy flour, miso, soy protein isolate, low-fat soy milk, veggie soy burger, textured vegetable protein, miso soup, cooked soybeans, soy hot dogs, and natto (fermented soy beans). APPLICATIONS: The soy food frequency questionnaire developed in this study provided highly reproducible estimates of soy food consumption and isoflavone intake. This instrument may be a useful tool in studies of the associations between isoflavone exposure and risk for chronic disease.
