Validation of the Test of Visual Perceptual Skills-Third Edition in patients with stroke

Purpose: The Test of Visual Perceptual Skills-Third Edition (TVPS-3) with seven subscales has been used to assess visual perception in patients with stroke. The purpose of this study was to investigate ecological validity, convergent validity, and discriminative validity of the TVPS-3 in patients with stroke.

Methods: One hundred patients were assessed with the TVPS-3, two measures of activities of daily living, and two cognitive measures. To examine ecological validity, we calculated correlations (Pearson’s r) among the TVPS-3 and two measures of activities of daily living. To examine convergent validity, correlations (r) were estimated among the TVPS-3 and two cognitive measures. To examine discriminative validity, independent t-test was used to compare the two groups with different levels of disability and to detect whether there were statistically significant differences in the TVPS-3 between these groups.

Results: The correlations were 0.21–0.48 among the TVPS-3 and two measures of activities of daily living. The correlations were 0.29–0.68 among the TVPS-3 and two cognitive measures. Between the two groups, the t-test results showed statistically significant difference (p?<?0.05) for the overall scale and the five subscales of the TVPS-3.

Conclusions: The TVPS-3 has acceptable convergent validity, ecological validity, and discriminative validity and is useful to assess the visual perception in patients with stroke.

• Implications for rehabilitation

• The Test of Visual Perceptual Skills-Third Edition is a motor free visual perception test, which is an adequate tool for use in patients with stroke.

• The Test of Visual Perceptual Skills-Third Edition showed acceptable ecological validity, convergent validity, and discriminative validity in patients with stroke.

Assessing the Validity of a Multidisciplinary Mini-Clinical Evaluation Exercise

Construct: The purpose of this study was to provide validity evidence for the mini-clinical evaluation exercise (mini-CEX) as an assessment tool for clinical skills in the workplace. Background: Previous research has demonstrated validity evidence for the mini-CEX, but most studies were carried out in internal medicine or single disciplines, therefore limiting generalizability of the findings. If the mini-CEX is to be used in multidisciplinary contexts, then validity evidence should be gathered in similar settings. The purpose of this study was to gather further validity evidence for the mini-CEX but in a broader context. Specifically we sought to explore the effects of discipline and rater type on mini-CEX scores, internal structure, and the relationship between mini-CEXs and OSCEs in a multidisciplinary context. Approach: During clerkship, medical students completed eight different rotations (family medicine, internal medicine, surgery, psychiatry, pediatrics, emergency, anesthesiology and obstetrics and gynecology). During each rotation, mini-CEX forms and a written examination were completed. Two multidisciplinary OSCEs (in Clerkship Year 3 and start of Year 4) assessed clinical skills. The reliability of the mini-CEX was assessed using Generalizability analyses. To assess the influence of discipline and rater type, mean scores were analyzed using a factorial analysis of variance. The total mini-CEX score was correlated to scores from the students' respective OSCEs and corresponding written exams. Results: Eighty-two students met inclusion criteria for a total of 781 ratings (average of 9.82 mini-CEX forms per student). There was a significant effect of discipline (p < .001, = .16), and faculty provided lower scores than nonfaculty raters (7.12 vs. 7.41; p = .002, = .02). The g-coefficient was .53 when discipline was included as a facet and .23 when rater type was a facet. There were low, but statistically significant correlations between the mini-CEX and scores for the 4th-year OSCE Total Score and the OSCE communication scores, r(80) = .40, p < .001 and r(80) = .29, p = .009. The mini-CEX was not correlated with the written examination scores for any of the disciplines. Conclusions: Our results provide conflicting findings for validity evidence for the mini-CEX. Mini-CEX ratings were correlated to multidisciplinary OSCEs but not written examinations, supporting the validity argument. However, reliability of the mini-CEX was low to moderate, and error accounted for the greatest amount of variability in scores. There was variation in scores due to discipline and resident raters gave higher scores than faculty. These results should be considered when considering the use of the mini-CEX in different contexts.     

Psychometric properties of the Five-Digit Test in patients with stroke

Purpose: To examine the ecological validity, predictive validity, and responsiveness of the Five Digit Test (FDT) in patients with stroke. Methods: We included inpatients with stroke (n?=?144, 114 and 105 in the ecological validity, predictive validity, and responsiveness analysis, respectively) in the study. At admission, the FDT and Barthel Index (BI) were assessed; at discharge, the FDT, BI, Postural Assessment Scale for Stroke Patients (PASS), and Mobility Subscale of the Stroke Rehabilitation Assessment of Movement (MO-STREAM) were assessed. Results: In the ecological validity analysis, the scores of the selective and alternating attention indices of the FDT were moderately correlated with those of the BI at admission and discharge (Spearman ρ?=?–0.38 to –0.45). In the predictive validity analysis, the scores of the two attention indices of the FDT at admission were moderately correlated with the scores of the BI, PASS, and MO-STREAM at discharge (ρ?=?–0.33 to –0.45). In the responsiveness analysis, the two attention indices of the FDT between admission and discharge had large differences (success rate difference?=?0.56–0.67, Wilcoxon Z?=?–5.90 to –6.60). Conclusion: Our results indicate that the selective and alternating attention indices of the FDT have acceptable ecological validity, predictive validity, and good responsiveness in patients with stroke.

• Implications for Rehabilitation

• The Five Digit Test (FDT), an efficient and culture-free assessment tool, has been used to assess selective attention and alternating attention

• The selective index and alternating attention index of the FDT showed acceptable ecological validity, predictive validity, and good responsiveness in patients with stroke.

     

Reliability and validity of the UTBAS-TR (The Unhelpful Thoughts and Beliefs Scale-the Turkish version) in the Turkish population

Abstract

Purpose: This paper decribes the development of the Turkish adaptation of UTBAS (UTBAS-TR) and reports the results concerning its applicability and psychometric structure.

Method: The sample consisted of 81 males and 19 females diagnosed with developmental stuttering in two centres. Test-retest reliability score was obtained by correlating results of repeated aplications of the scale within a one-week interval and a paired t-test was calculated to see the differences in the total and UTBAS I, II and III scores. The internal consistency was assessed using the Cronbach’s alpha. Construct validity was also assessed by examining inter-scale correlations and with the correlations of the UTBAS-TR with two other scales (State-Trait Anxiety Inventory (STAI) and Beck Anxiety Inventory (BAI)).

Result: The internal consistency of the UTBAS-TR and the test and retest reliability score was stati?stically significant. The correlation between UTBAS-TR total score and the UTBAS-TR I, II and III correlations were high. A significant correlation was observed between UTBAS-TR total score with State Anxiety Inventory. However, the correlations between UTBAS-TR-Total Score and Trait Anxiety Inventory and Beck Anxiety Inventory were low.

Conclusion: The UTBAS-TR proved to be suitable for use with the Turkish population.     

Construct validation of the English version of Readiness for Interprofessional Learning Scale (RIPLS): Are Chinese undergraduate students ready for ‘shared learning’?

Interprofessional education has been receiving attention as a result of research suggesting the benefits of interpersonal collaboration in healthcare. In Hong Kong, the implementation of the Interprofessional Team-based Learning programme provides implicit call to study the psychometric properties of Readiness for Interprofessional Learning Scale (RIPLS) to clarify if this is a valid measure when used in the Chinese undergraduate healthcare context. This study examines the psychometric properties of RIPLS involving predominantly Chinese undergraduate healthcare students in Hong Kong. Using within- and between-network approaches to construct validity, we investigated the applicability of English version of RIPLS among 469 predominantly Hong Kong Chinese students who have competence in the English language. These participants were from complementary health professional programmes: biomedical sciences, chinese medicine, medicine, nursing, and pharmacy, from two universities in Hong Kong. The within-network test results indicated that RIPLS had good internal consistency reliability. Results of the confirmatory factor analysis lend support to the overall factor structure of hypothesized four-factor solution although one item obtained non-significant factor loading. The between-network test also suggests that various subscales of RIPLS correlated systematically with theoretically relevant constructs: collective efficacy, team impact on quality of learning, and team impact on clinical reasoning ability. The RIPLS is a valid measure to estimate the Chinese undergraduate healthcare students’ readiness to engage in interprofessional learning.     

Modification of the Diagnostic Content Validity Model

Diagnostic content validation of nursing diagnoses is a recommended means to confirm the defining characteristics necessary to establish a specific nursing diagnosis. The diagnostic content validity model has been used in numerous studies to develop lists of major and minor defining characteristics recommended by experts as being present in patients with specific diagnoses. The authors provide an overview of the diagnostic content validity model, review the meaning and purposes of content validity, discuss problems with information processing, and suggest revisions to the diagnostic content validity model. Incorporation of these changes may improve the usability of nursing diagnoses in clinical practice, education, and research.     

Adaptation and validation of the Iranian version of Angina Pectoris characteristics questionnaire

Research aimed at evaluating Angina Pectoris (AP) symptoms in patients with Coronary Heart Disease (CHD) requires a comprehensive assessment tool applicable to this population. Because no single existing measure assessed the full range of symptom characteristics important to our study, we combined two measures (the modified Rose Questionnaire (MRQ), and the Short Form‐McGill Pain Questionnaire (SF‐MPQ) and added one item to examine specific aspects of AP symptoms (Accompanying Symptom Checklist). The purposes of this study are: (i) to describe the process of translating the SF‐MPQ, MRQ and accompanying symptom checklist from English to the Farsi language; and (ii) to evaluate substantial psychometric works (content and construct validity) for the entire instrument and each part of it (SF‐MPQ, MRQ and accompanying symptom checklist). A cross‐cultural adaptation of the instrument was carried out before developing the final version of it. To these ends, one hundred and 10 CHD patients with AP were assessed by this hybrid measure in an initial study. An analysis of the results indicated that a content valid instrument had been developed. There was a significantly high correlation between scores in the SF‐MPQ and there were associations between items in the MRQ. The Iranian version of AP characteristics questionnaire is valid; it is capable of describing characteristics of AP symptoms. However, the reliability of the instrument needs to be assessed through further research.

Study of the reliability and validity of the Community Health Intensity Rating Scale (CHIRS) in the Turkish community

The purpose of this study was to examine the reliability and validity of the Community Health Intensity Rating Scale (CHIRS) that was translated into the Turkish language and applied in the Turkish community. The CHIRS is a tool that assesses the intensity of need for care of persons/families in the community. The original version of the tool was translated into Turkish, examined for face validity and language appropriateness by the Turkish experts, and then applied to 372 families living in Odemis, Turkey. Significant correlations were found between total scale score (TSS) and total number of household members, and between the TSS and the total number of visits to any health institution within the previous month. In addition, the self-health care needs evaluation scores supported predictive validity. For reliability, min-max values, standard errors and deviations, skewness, and kurtosis coefficients of parameter scores, domain scores, and TSS were examined. The mean TSS was 26.7 (+/- 5.32) and the mean age of the participants was 35.0 years. For internal consistency, Cronbach's alpha (.525) and Guttman split-half coefficient (.629) values were established for the TSS. In conclusion, the reliability and validity of the Turkish version of CHIRS have been established.

Validity and reliability of the Turkish translation of the Pediatric Evaluation of Disability Inventory (PEDI)

Purpose. To investigate the validity and reliability of the Turkish translation of the original Pediatric Evaluation of Disability Inventory (PEDI).

Method. On May 2003, we received permission from Boston University to translate and use the PEDI for Research purposes. PEDI Functional Skills scale and Caregiver Assistance scale was administered by physiatrists to 573 healthy Turkish children (295 males and 278 females; the age range: 7 months to 7½ years) in two different healthcare centres in Ankara. The Turkish translation of the PEDI was again administered to 102 children after five days in order to assess test-retest reliability. Intraclass correlation coefficients (ICC) and Cronbach's alphas (α) were calculated. The test-retest reliability was assessed by Spearman's correlation coefficient. Internal construct validity was assessed by using Rasch unidimensional measurement model.

Results. High Cronbach's α coefficients (≥0.98), high ICC values (≥0.96) and high Spearman correlation coefficients (≥0.86) were found. The internal construct validity was confirmed by good fit to the Rasch measurement model. The fit statistics conducted in the study was acceptable, except for some items.

Conclusions. The Turkish translation of the PEDI is valid and reliable for the Turkish child population. We believe that PEDI is a detailed and useful instrument for the evaluation of efficiency of pediatric rehabilitation programme.     

Adaptation and psychometric evaluation of the Swedish version of the Good Nursing Care Scale for Patients

The aim of this study was to adapt the instrument 'Good Nursing Care Scale for Patients' to Swedish conditions as a measure of patients' satisfaction, as well as estimating its reliability and validity. Following a pilot test, discussions in the author group, testing for readability among patients and judgement of content validity by a panel of experts, the final version was reduced to 72 items focusing on good caring. The refined instrument was assessed for internal consistency in 447 surgical in-patients, for 2 week test-retest reliability in 100 patients and subjected to orthogonal principal components factor analysis with varimax rotation, followed by second-order factor analysis. The internal consistency item-item correlation coefficient ranged from 0.15 to 0.91, correlation between each item and the total scale was >or=0.30 for 70 items, Cronbach's alpha coefficient for the final scale was 0.79 and test-retest reliability was 0.75. An orthogonal principal components factor analysis with varimax rotation was conducted on the final 71 items and the 15 first-order factors with eigenvalues >or=1 explained 66% of the total variance. A second-order factor analysis of these 15 factors as items resulted in a seven-factor solution. The total variance explained by the seven factors was 79%. Cronbach's alpha coefficient for the seven factors ranged between 0.32 and 0.95. The instrument seems reliable and valid to assess the patients' satisfaction with what happened during their hospital stay. To confirm the factor structure and improve factor consistency additional development and testing is suggested.     

Cross-validation and discriminant validity of Adolescent Health Promotion Scale among overweight and nonoverweight adolescents in Taiwan

This study used cross-validation and discriminant analysis to evaluate the construct and discriminant validity of Adolescent Health Promotion (AHP) scale between the overweight and nonoverweight adolescents in Taiwan. A cross-sectional survey method was used and 660 adolescents participated in this study. Cluster and discriminant analyses were used to analyze the data. Our findings indicate that the AHP is a valid and reliable scale to discriminate between the health-promoting behaviors of overweight and nonoverweight adolescents. For the total scale, cluster analyses revealed two distinct patterns, which we designated the healthy and unhealthy groups. Discriminate analysis supported this clustering as having good discriminant validity, as nonoverweight adolescents tended to be classified as healthy, while the overweight tended to be in the unhealthy group. In general, overweight adolescents practiced health-related behaviors at a significantly lower frequency than the nonoverweight. These included exercise behavior, stress management, life appreciation, health responsibility, and social support. These findings can be used to further develop and refine knowledge of adolescent overweight and related strategies for intervention.
