OBJECTIVE: To evaluate the concurrent validity of the Arm Motor Ability Test (AMAT) using the Fugl-Meyer Assessment (FMA) as the criterion measure of poststroke upper limb motor impairment. DESIGN: Upper limb motor impairment and arm ability of 30 chronic stroke survivors were assessed with the FMA and AMAT, respectively. Spearman's correlation coefficients were generated relating the components of FMA and AMAT. Scatterplots were generated to provide qualitative assessments of the relationship between FMA and AMAT. Bar graphs of FMA and AMAT normalized to their maximum scores were generated to compare the levels of motor status measured by each instrument. RESULTS: All components of AMAT correlated highly with FMA total (r = 0.92-0.94; P < 0.001). AMAT functional ability and AMAT quality of movement were linearly related with FMA total. However, AMAT time of performance exhibited significant ceiling and floor effects with respect to FMA. Normalized AMAT scores were generally lower than normalized FMA scores (P < 0.001), with the greatest difference in scores observed in subjects with more severe motor impairments. CONCLUSION: This study demonstrates a high degree of concurrent criterion validity of the AMAT. However, AMAT tends to underestimate the arm motor status of those with more severe motor impairments.  相似文献

Background

To achieve the goal of increasing the proportion and duration of breastfeeding in Taiwan, it is essential to assess the role of attitudes in determining which method of infant feeding will be chosen. Understanding maternal attitudes toward infant feeding methods may have utility in the development and implementation of public health policy and interventions facilitating increasing breastfeeding rates. However, no validated instrument to assess breastfeeding attitudes is available in Chinese for use in Taiwan.

Objective

To translate the Iowa Infant Feeding Attitude Scale (IIFAS) into Chinese and assess its psychometric properties among Taiwanese breastfeeding women.

Design

Methodological study.

Setting

One public hospital in Taichung city, Taiwan.

Participants

A convenience sample of 140 in-hospital breastfeeding women was recruited.

Methods

The IIFAS was translated into Chinese using forward translation, back-translation, semantic equivalence, and pilot testing. Predict validity and internal consistency was assessed. The final sample consisted of 120 women (14% attrition) that were interviewed by telephone at 6 weeks postpartum to record the breastfeeding duration and infant feeding method.

Results

One item was modified to better reflect the item content. In-hospital IIFAS scores significantly predicted breastfeeding duration as well as exclusive breastfeeding at 6 weeks postpartum. The Cronbach's alpha coefficient for internal consistency was 0.74.

Conclusions

This study provides evidence that the Chinese version of the IIFAS can be considered valid and reliable scale for assessing attitudes toward breastfeeding among breastfeeding women in Taiwan.  相似文献

Background

Taiwan is facing the dilemma of a rapidly growing elderly population and there is a perceived need for greater gerontological education. Several universities have recently started providing elective gerontological certification programs. In order to provide useful and sufficient information to increase students’ knowledge and attitudes, to develop a reliable and valid instrument is essential and helpful for faculty as well as the program director to pinpoint students’ strengths and weaknesses.

Objective

To assess the reliability and validity of a Chinese version of Kogan's Attitudes toward Older People (KAOP) among medical and nursing students at a medical university.

Method

A two-phase data collection design was used. Two weeks following the first completion, another KAOP form, was given. Content validity, construct validity, internal consistency, and stability reliability were assessed. The final sample consisted of 275 students.

Results

Scores were between 34 and 238. The study sample reported slightly positive attitudes (144.3 ± 17.89), with half of the subjects (50.1%) above average. All of the 34 items were found to have significant item-to-total correlations (p < .05). Two factors were extracted, Appreciation and Prejudice. The Prejudice and Appreciation contributed 33.6% and 21.1% to the variance. The Cronbach's alpha was .82 for the total scale (.83 for Prejudice, .81 for Appreciation). Stability was 0.86 for Prejudice and 0.91 for Appreciation.

Conclusions

The Chinese version of the KAOP can be considered reliable and valid scale for assessing the attitudes toward older people.  相似文献

BACKGROUND: Social support is an important factor in the rehabilitation process, as it has a positive influence on patients' health, functioning and recovery. In particular, perceived social support and instrumental support are important after total hip or knee arthroplasty. However, nursing staff often appear to estimate the amount of support available to patients by number of visitors. Until now, no suitable Dutch-language scale was available to measure social support in orthopaedic patients. AIM: The aim of this paper is to describe the development and initial validity and reliability testing of the Groningen Orthopaedic Social Support Scale, a self-report questionnaire to measure social support in patients after total hip or knee arthroplasty. METHODS: A total of 119 people who had had arthroplasty completed the Groningen Orthopaedic Social Support Scale and a control scale. The reliability and validity of the questionnaire were analysed. RESULTS: Reliability of the Groningen Orthopaedic Social Support Scale can be considered satisfactory, with a Cronbach's alpha of 0.89. Analysis of construct validity by means of factor analysis yielded two factors: perceived social support and instrumental support. A Pearson's correlation between these subscales was moderate (r = 0.61 and statistically significant). Concurrent validity can be considered satisfactory, with a Pearson correlation of 0.72 (P < 0.001) between the Groningen Orthopaedic Social Support Scale and the control list. CONCLUSIONS: The Groningen Orthopaedic Social Support Scale can be considered suitable for measuring social support. It can be used to help nursing staff determine if a patient's need for social support is fulfilled, and to advise family and friends on the basis of the results. The questionnaire can also be used to establish the role of social support as a factor in supportive interventions during and after hospital stay.  相似文献

The Patient Learning Needs Scale: reliability and validity   总被引:1,自引:1,他引:1  
The article describes the development and initial psychometric evaluation of an instrument to measure patients' perceptions of learning needs at time of discharge from hospital to home. Evaluation of the Patient Learning Needs Scale was based on responses of 301 adults hospitalized with a medical or surgical illness. Factor analysis isolated seven subscales: medications, activities of living, feelings related to condition, community and follow-up, treatment and complications, enhancing quality of life and skin care. These seven factors accounted for 56.1% of the variance. Cronbach's alpha for the 50-item scale was 0.95.  相似文献

PurposeThe aim of this methodological study was to determine the validity and reliability of the Diabetes Self-Efficacy Scale adapted to the Turkish community.MethodsThe study sample was completed with 319 patients who had been diagnosed at least 1 year before and hospitalized in the Malatya Turgut Ozal Health Center and Malatya State Hospital in Turkey. A questionnaire that consists of items on sociodemographic characteristics, drug use and information about the disease of patients and the Diabetes Self-Efficacy Scale were used for data collection in the study. In reliability analysis of the scale, the Cronbach's α coefficient was calculated and item analysis method was utilized. Factor analysis was used for the construct validity, and Principal Component Analysis and Varimax Rotation method were used for analyzing the factor structures.ResultsAccording to data obtained in the study, item-total correlation of the items of the scale was found to be at an adequate level (0.297–0.803). The scale's Cronbach's α reliability coefficient was found to be 0.86, and there was one factor that explains 52.38% of the total variance with an eigenvalue was greater than 1.0. As a result of the analysis, the factor loadings of the items of the scale were found to be between 0.59 and 0.81.ConclusionDiabetes Self-Efficacy Scale is a valid and reliable instrument for determining the self-efficacy of patients and providing a proper care. It can be suggested to investigate and evaluate the consistency of the scale by applying it to broader sample groups representing different socioeconomic levels.  相似文献

Discomfort is a common problem for wheelchair users. Few researchers have investigated discomfort among wheelchair users or potential solutions for this problem. One of the impediments to quantitative research on wheelchair seating discomfort has been the lack of a reliable method for quantifying seat discomfort. The purpose of this study was to establish the test-retest reliability, internal item consistency, and concurrent validity of a newly developed Wheelchair Seating Discomfort Assessment Tool (WcS-DAT). Thirty full-time, active wheelchair users with intact sensation were asked to use this and other tools in order to rate their levels of discomfort in a test-retest reliability study format. Data from these measures were analyzed in SPSS using an intraclass correlation coefficient (ICC) model (2,k) to measure the test-retest reliability. Cronbach's alpha was used to examine the internal consistency of the items within the WcS-DAT. Concurrent validity with similar measures was analyzed using Pearson product-moment correlations. ICC scores for all analyses were above the established lower bound of .80, indicating a highly stable and reliable tool. In addition, alpha scores indicated good consistency of all items without redundancy. Finally, correlations with similar tools, such as the Chair Evaluation Checklist and the Short Form of the McGill Pain Questionnaire, were significant at the .05 level, and many were significant at the .001 level. These results support the use of the WcS-DAT as a reliable and stable tool for quantifying wheelchair seating discomfort. Its application will enhance the ability to assess and to research this important problem and will provide a means to validate the outcomes of specialized seating interventions for the study population of wheelchairs users.  相似文献

Research into the pathophysiology and treatment of hypertrophic scar (HSc) remains limited by the heterogeneity of scar and the imprecision with which its severity is measured. The objective of this study was to test the interrater reliability and concurrent validity of the Cutometer measurement of elasticity, the Mexameter measurement of erythema and pigmentation, and total thickness measure of the DermaScan C relative to the modified Vancouver Scar Scale (mVSS) in patient-matched normal skin, normal scar, and HSc. Three independent investigators evaluated 128 sites (severe HSc, moderate or mild HSc, donor site, and normal skin) on 32 burn survivors using all of the above measurement tools. The intraclass correlation coefficient, which was used to measure interrater reliability, reflects the inherent amount of error in the measure and is considered acceptable when it is >0.75. Interrater reliability of the totals of the height, pliability, and vascularity subscales of the mVSS fell below the acceptable limit ( congruent with0.50). The individual subscales of the mVSS fell well below the acceptable level (< or =0.3). The Cutometer reading of elasticity provided acceptable reliability (>0.89) for each study site with the exception of severe scar. Mexameter and DermaScan C reliability measurements were acceptable for all sites (>0.82). Concurrent validity correlations with the mVSS were significant except for the comparison of the mVSS pliability subscale and the Cutometer maximum deformation measure comparison in severe scar. In conclusion, the Mexameter and DermaScan C measurements of scar color and thickness of all sites, as well as the Cutometer measurement of elasticity in all but the most severe scars shows high interrater reliability. Their significant concurrent validity with the mVSS confirms that these tools are measuring the same traits as the mVSS, and in a more objective way.  相似文献

Abstract The purpose of the present study was to determine the reliability and validity of the Sternal Wound Infection Prediction Scale. The tool was developed to fill the need for a quick and easy way to determine which patients are at risk of developing a sternal wound infection in order that preventive measures can be instituted. Data were collected by a retrospective chart review of 56 patient records, 27 who developed a sternal wound infection and 29 who did not. In this group of patients, obesity and diabetes were found to be statistically significant risk factors. Pharmacological support was found to be a clinically significant factor. Of the infected group, 68.4% of patients who developed a sternal wound infection were predicted to do so by the tool.  相似文献

Cognitive and behavioral impairment are a major source of disability in daily living of patients with traumatic brain injury (TBI). The Neurobehavioral Rating Scale-Revised (NRS-R) is a short, easy-to administer interview tool developed to improve assessment by clinicians. Data are available on its criterion validity and reliability, but the concurrent validity of the French NRS-R was not yet documented. OBJECTIVE: To assess the concurrent validity of the NRS-R with current psychometric tests. METHOD: One hundred and four patients with TBI enrolled in a community adjustment program underwent concurrent examination with the NRS-R, cognitive tests assessing memory, attention, and executive functions, and scales of anxiety (STAI) and depressive mood (CES-D). Intercorrelations were undertaken between these variables and the five factors of the NRS-R: F1, intentional behavior; F2, lowered emotional state; F3, survival-oriented behaviour/hightened emotional state; F4, arousal state; and F5, language. Patients were 82 men and 22 women, the mean age was 28.5 years, and 70% had severe TBI (Glasgow coma score [GCS] below 8 on admission). They were assessed 52 months on average after their injury. RESULTS: Factor F1 was correlated with results on the GCS (P<0.05), the Tower of London test (TL, P<0.01), the Trail Making Test (TMT, P<0.01), divided attention (DA) and inhibition (IN) subscales of the Zimmermann and Fimm's Attention battery (TEA) (P<0.01) and reverse digit span (DS, P<0.05). Factor F2 was positively related to age at injury, time since injury (TSI) (P<0.05) and CESD and STAI scores (P<0.001). Factor F3 was related to DA (P<0.01) TL scores and TSI (P<0.05). Factor F4 was related to TL, TMT, DA, flexibility, DS (P<0.05), TSI, duration of post-traumatic amnesia, CES-D score (P<0.05) and STAI scores (P<0.01). Factor F5 was related to GCS, DA (P<0.05), and reaction time on the subscales IN and Go/nogo (GO) of the TEA battery (P<0.01). The NRS-R total score was related to CESD, STAI scores, TMT score, DA (P<0.01) and TL score, IN and GO scores and TSI (P<0.05). DISCUSSION: As McCauley et al found with the English version of the NRS-R, significant relationships were found between NRS-R factor scores, cognitive tests and emotional scales. Relationships were also found between factor scores and indicators of injury severity and time since injury. These data suggest fair concurrent validity of the NRS-R.  相似文献
