    Developing a valid and reliable self-efficacy in clinical performance scale

    INTERNATIONAL NURSING REVIEW, Issue 2 2009
    F. Cheraghi phd
    Aim:, This paper describes the development and testing of the Self-Efficacy in Clinical Performance (SECP) instrument for nursing students. Background:, Accurate measurement of self-efficacy can be used to predict nursing students' clinical performance. The literature review indicated there is no existing self-efficacy in clinical performance instrument for Iranian nursing students. Methods:, To clarify the concept of self-efficacy in clinical performance, 28 semi-structured interviews and three focus groups were conducted. A self-efficacy framework with well-developed theoretical constructs was formed. A review of literature and content analysis of the interview transcripts identified subscales and items to be included in the instrument. Then, a methodological design was used. The SECP was developed into 69 Likert-format items, which were evaluated by 20 nursing experts in the form of content validity index. The scale's validity and reliability were tested in a randomized sample of 207 final year nursing students. Findings:, The final scale consists of four dimensions with 37 items. The overall scale internal reliability had , = 0.96; the dimensions Cronbach's , ranged from 0.90 to 0.92. Test,retest reliability with a 2-week time interval was: r = 0.94. In addition, concurrent validity was obtained (r = 0.73, P = 0.01). Conclusions:, The SECP has demonstrated evidence of content validity, construct validity, concurrent validity, internal consistency reliability and stability. Statistical analysis provided an objective tool for assessing nursing students' self-efficacy in clinical performance. It may have been fruitful to further test the instrument with students from other years of their education. [source]

    A psychometric evaluation of the Chinese version of the Cardiovascular Limitations and Symptoms Profile in patients with coronary heart disease

    Aims and objectives., The aim of this study was to translate from English and evaluate the validity, reliability and cultural relevance of the Cardiovascular Limitations and Symptoms Profile (CLASP) as a health-related quality-of-life (HRQL) measure in Chinese patients with coronary heart disease. Background., Improvement in HRQL is increasingly used as a primary outcome in determining the treatment benefit using a generic instrument. However, disease-specific instruments are being cited as more responsive and sensitive in detecting even the smallest changes in health status. Therefore, valid and reliable disease-specific measures for patients with coronary heart disease are now being developed and evaluated. Design., Questionnaire design. Methods., The translation equivalence and content validity of the Chinese version of CLASP were evaluated by an expert panel. Measurement performance was tested on a convenience sample of 369 Chinese coronary heart disease patients. Results., The instrument demonstrated good content validity (content validity index 0ˇ94), acceptable internal consistency (>0ˇ70), except for two subscales of angina and tiredness and significant positive correlations among the subscales of CLASP, Hospital Anxiety Depression Scale and the Short Form 36 Health Survey. Principal components analysis revealed nine factors that together explained 69% of the variance. Conclusions., The results of this study support that CLASP is a valid and reliable disease-specific health status measure for Chinese patients with coronary heart disease. However, further item modifications and testings are needed when considering the cross-cultural context. Relevance to clinical practice., The use of disease-specific HRQL measures could effectively evaluate nursing interventions in clinical practice. Further validations of CLASP among different diagnostic groups, such as patients with heart failure and those who have survived an acute myocardial infarction, would provide further empirical support for its use with all patients with heart disorders.

    Aim., To assess the psychometric properties of the Chinese version of the Satisfaction with the Nursing Home Instrument. Background., Resident's satisfaction has been regarded by the literature as a gold standard for quality of nursing home care. Accurate assessment of resident's satisfaction can provide valuable information for implementation of quality nursing home care. However, there is not a validated Chinese tool to serve the purpose. Design., A cross-sectional descriptive survey design. Methods., Content validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by the use of expert panel. Construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was determined by assessing the correlation between satisfaction with other theoretically related constructs. Internal consistency and stability of the Chinese version of the Satisfaction with the Nursing Home Instrument were determined by Cronbach's method and two-week test,retest reliability. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was assessed by confirmatory factor analysis. Testing was performed on a cluster sample of 330 residents from 16 nursing homes in Hong Kong. Results., The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated good content validity by having content validity index of 0ˇ93. High construct validity of the Chinese version of the Satisfaction with the Nursing Home Instrument was supported by its significant correlation with depression (r = ,0ˇ42, P = 0ˇ000), health-related quality of life (physical component) (r = 0ˇ16, P = 0ˇ042), health-related quality of life (mental component) (r = 0ˇ41, P = 0ˇ000) and global quality of care (r = 0ˇ49, P = 0ˇ000). The Chinese version of the Satisfaction with the Nursing Home Instrument demonstrated satisfactory internal consistency and good stability by having Cronbach's alpha of 0ˇ79 and intra-class correlation coefficient of 0ˇ94, respectively. The six-factor structure of the Chinese version of the Satisfaction with the Nursing Home Instrument was not fully supported by confirmatory factor analysis. Conclusions., The Chinese version of the Satisfaction with the Nursing Home Instrument is a useful instrument for assessing satisfaction of cognitively intact Chinese nursing home residents. Findings provided initial evidence on its validity and reliability. Further empirical testing is recommended to explore its factor structure. Relevance to clinical practice., The Chinese version of the Satisfaction with the Nursing Home Instrument can provide guidance to enhance delivery of high-quality nursing home care for the Chinese population.

    Validity of the Danish Prostate Symptom Score questionnaire in stroke

    ACTA NEUROLOGICA SCANDINAVICA, Issue 6 2009
    S. Tibaek
    Objective,,, To determine the content and face validity of the Danish Prostate Symptom Score (DAN-PSS-1) questionnaire in stroke patients. Materials and methods,,, Content validity was judged among an expert panel in neuro-urology. The judgement was measured by the content validity index (CVI). Face validity was indicated in a clinical sample of 482 stroke patients in a hospital-based, cross-sectional survey. Results,,, I-CVI was rated >0.78 (range 0.94,1.00) for 75% of symptom and bother items corresponding to adequate content validity. The expert panel rated the entire DAN-PSS-1 questionnaire highly relevant (S-CVI = 1.00). No experts suggested items omitted or improved. The response rate was 84% and face validity had an acceptable level of completed response for each symptom items (96,98%) and bother items (93,96%) indicating that all items were well interpreted. Conclusion,,, The DAN-PSS-1 questionnaire appears to be content and face valid for measuring lower urinary tract symptoms after stroke. [source]

    Item selection and content validity of the Critical-Care Pain Observation Tool for non-verbal adults

    Abstract Title.,Item selection and content validity of the Critical-Care Pain Observation Tool for non-verbal adults. Aim., This paper is a report of the item selection process and evaluation of the content validity of the Critical-Care Pain Observation Tool for non-verbal critically ill adults. Background., Critically ill patients experience moderate to severe pain in the intensive care unit. While critical care clinicians strive to obtain the patient's self-report of pain, many factors compromise the patient's ability to communicate verbally. Pain assessment methods often need to match the communication capabilities of the patient. In non-verbal patients, observable behavioural and physiological indicators become important indices for pain assessment. Method., A mixed method study design was used for the development of the Critical-Care Pain Observation Tool in 2002,2003. More specifically, a four-step process was undertaken: (1) literature review, (2) review of 52 patients' medical files, (3) focus groups with 48 critical care nurses, and interviews with 12 physicians, and (4) evaluation of content validity with 17 clinicians using a self-administered questionnaire. Results., Item selection was derived from different sources of information which were convergent and complementary in their content. An initial version of the Critical-Care Pain Observation Tool was developed including both behavioural and physiological indicators. Because physiological indicators received more criticism than support, only the four behaviours with content validity indices >0ˇ80 were included in the Critical-Care Pain Observation Tool: facial expression, body movements, muscle tension and compliance with the ventilator. Conclusion., Item selection and expert opinions are relevant aspects of tool development. While further evaluation is planned, the Critical-Care Pain Observation Tool appears as a useful instrument to assess pain in critically ill patients. [source]
