Psychometric evaluation of the Chinese version of the State Anxiety Scale for Children

The assessment of anxiety in children undergoing surgery must be addressed before any intervention can be appropriately planned, provided, and evaluated. The purpose of this study was to evaluate the psychometric properties of the Chinese version of the State Anxiety Scale for Children. Two hundred and thirty-seven children from a primary school and 112 children admitted for day surgery were recruited for this study. The instrument demonstrated adequate internal-consistency reliability, appropriate concurrent validity, and construct validity. Factor analyses further confirmed the construct validity of the scale, with a good fit between the factor structure of the scale and the observed data. Results suggest that the Chinese version of the State Anxiety Scale for Children can be used as a self-report assessment tool in measuring the anxiety level of Chinese children ages 7-12 years.     

Factorial structure of the Chinese version of the State Anxiety Scale for Children (short form)

Aim.  The present study aimed at examining the factorial structure of the Chinese version of the State Anxiety Scale (Short form), using exploratory and confirmatory analyses. Background.  The factorial structure of the short form of the Chinese version of the State Anxiety Scale for Children has neither been examined by using exploratory factor analysis nor been examined by confirmatory factor analysis. Consequently, whether the factor structure of the short form is congruent with the hypothesised configuration of the factor structure of the full form cannot be confirmed. Design.  Survey. Method.  A test–retest, within‐subjects design was employed. Two hundred children (7–12 years of age) admitted for surgery in a day surgery unit was invited to participate in the study. They were asked to respond to the Chinese version of the State Anxiety Scale (short form) before surgery and upon discharge home. Results.  The results of exploratory factor analysis showed that there are two factors underlying the short form, which is congruent with hypothesised configuration of the factor structure of the full form. Confirmatory factor analysis confirmed the construct validity, with a good fit between the factor structure of the short form and the observed data. Conclusion.  This study addressed a gap in the literature by examining the factorial structure of the short form. The results confirmed the factor structure of the short form is congruent with the hypothesised configuration of the factor structure of the full form. Relevance to clinical practice.  The availability of a valid, reliable and convenient instrument is crucial in evaluating the effectiveness of nursing interventions. The findings also suggest that the short form is an objective assessment tool and can be used by clinical nurses as objective assessment tool in measuring anxiety level of Chinese children in busy clinical settings, where time constraints make the use of the full form unfeasible.

cao x.y., Liu X.H., tian l. & guo y.q. (2013) Journal of Nursing Management  21 , 657–667 The reliability and validity of the Chinese version of nurses’ self-concept questionnaire Aim To examine the reliability and validity of the Chinese version of nurses’ self-concept questionnaire. Background Nurses’ self-concept is important to alleviate the current shortage of nurses. Nurses’ self-concept questionnaire is an effective instrument to measure nurses’ self-perception of professional competencies. However, the psychometric properties of the Chinese version have not been tested. Methods A two-stage research design was used in this study. At Stage 1347 registered nurses were recruited to establish the psychometric properties of the Chinese version. At Stage 2, a confirmatory factor analysis was used to examine the extracted factor structure from Stage 1 with 1017 respondents as a sample. Results The internal consistency of the Chinese version was 0.95 and the test–retest reliability was 0.83. The exploratory factor analysis extracted six dimensions. The findings at Stage 2 showed an acceptable model fit and discriminant validity. The Chinese version was a significant predictor of Maslach Burnout Inventory (β = −0.58; P = 0.00). Conclusions This study verified the psychometric properties of the Chinese version of nurses’ self-concept questionnaire. Implication for nursing management The Chinese version of nurses’ self-concept questionnaire will facilitate the evaluation of professional self-concept among nurses and help to develop the individualized self-concept strategies.

Reliability and validity of the Chinese version of the Worry Scale

This article presents the findings on the development and validation of a Chinese version of the Worry Scale (WS), a measure of worry about hypoglycemia. A previously developed 16-item WS was back-translated and applied to 117 Chinese diabetic patients living in Hong Kong. An iterative process of factor and item analyses identified a unidimensional 10-item Chinese WS (WS-10), which accounted for 57.15% of the total variance. Cronbach's alpha was 0.91. Strong correlation was demonstrated between the WS-10 and WS with 16 items (r = 0.97, p = 0.000). Comparing the level of worry about hypoglycemia between Type 1 and Type 2 diabetic patients established a contrast-group validity of the WS-10 (p = 0.002). Criterion validity was established by correlating the WS-10 with the respondents' glycosylated hemoglobin (r = -0.29, p = 0.002). Test-retest reliability using intraclass correlation (ICC) was established, ICC(1, 1) = 0.68. As the clinical administration of this scale takes less than 5 min, the Chinese WS-10 offers a useful instrument to identify patients with high levels of worry about hypoglycemia for clinical and education interventions. It also provides public health nurses with a reliable and valid prepost measure of intervention effectiveness. The Chinese WS-10 will facilitate further research about the effects of worry concerning hypoglycemia on self-care behaviors with the Chinese populations.

The Persian version of the Berg Balance Scale: inter and intra-rater reliability and construct validity in elderly adults

Purpose: As a well-known measure for quantifying functional mobility in elderly persons, Berg Balance Scale (BBS) was used in the present study to evaluate its psychometric properties among a sample of 106 elderly individuals speaking Persian language. Method: After forward-backward translation process, videotapes were recorded from all participants while performing 14 tasks of the BBS. The volunteers were also asked to perform the Timed Up and Go (TUG) test at the same session. To determine inter and intra-rater reliability, the videotapes were viewed by two experienced therapists while one of the raters assessed the videotaped performance of the subjects on a second occasion. Results: Intraclass correlation coefficients (95% confidence interval) of 0.93 (0.87 0.96) and 0.95 (0.92 0.97) were obtained for inter and intra-rater reliability, respectively. Cronbach’s alpha was 0.62 which is marginally lower than the cut-off point of 0.70. Furthermore, there were no ceiling and floor effects for the Persian version. In terms of construct validity, the BBS had a negative and strong correlation with the TUG (r?=??0.74, p < 0.001). Conclusions: Acceptable levels of intra and inter-rater reliability with a moderate internal consistency and high validity were demonstrated for the Persian version of BBS.

Implications for Rehabilitation

• The results on psychometric properties of the Persian BBS are comparable with the Italian, Brazilian, Norwegian, Turkish and Taiwanese versions of BBS.

• The Persian BBS seems to be a reproducible and standardized clinical instrument for use in community-dwelling elderly population.

• The Persian BBS can be used in geriatrics clinical settings and future outcome researches to assess balance abilities of Iranian older adults.

The Psychometric Properties of Taiwanese Version of the Memorial Anxiety Scale for Prostate Cancer

ContextThe Memorial Anxiety Scale for Prostate Cancer (MAX-PC) has been used in different countries to assess the specific anxiety of patients with prostate cancer.ObjectivesThis research aims to test the reliability and validity of the Taiwanese version of the MAX-PC (MAX-PC-T).MethodsPatients with prostate cancer in the urology clinics of three hospitals are recruited via a convenience sampling. Patients completed the MAX-PC-T, Positive and Negative Affect Schedule (PANAS), and the Short Form (SF)-12 Health Survey. The internal consistency is tested to determine the reliability of the MAX-PC-T. The correlation among the MAX-PC-T, PANAS, and SF-12 is used to test concurrent and discriminant validity. Confirmatory factor analysis is performed to determine the convergent and discriminant validity of the scale.ResultsThe MAX-PC-T conforms to the three structures of the original MAX-PC, which includes the prostate cancer anxiety subscale, prostate-specific antigen anxiety subscale, and fear of recurrence subscale. The factor loading of the items in each subscale is >0.50. The MAX-PC-T was significantly negatively correlated with the positive affect subscale of the PANAS and the mental component summary of the SF-12 and significantly positively correlated with the negative affect subscale of the PANAS. Cronbach's α value of internal consistency is 0.94 in the MAX-PC-T.ConclusionThe MAX-PC-T demonstrates appropriate reliability and validity. It can be used with patients with prostate cancer to assess their specific anxiety.
