Validity of the Dictionary of Occupational Titles as applied to construction site workers in Hong Kong.

This study was designed to examine the content validity of the Dictionary of Occupational Titles (D.O.T.) as applied to construction site workers in Hong Kong. The study was divided into the First Expert Panel Review, the Second Expert Panel Review and the Field Study. The results indicated that (i) 15 out of the 55 items of the D.O.T. were identified as insignificant job requirements, and 14 items other than those suggested by the D.O.T. were identified as significant job requirements by the First Expert Panel; (ii) criteria of 20 out of the 40 items of the job requirements as suggested by the D.O.T. were identified as different from the ones suggested by the Second Expert Panel; and (iii) criteria of 4 items were found to be different among the D.O.T., the Second Expert Panel and the Field Study. The results of this study substantiate the claim that the validity of the D.O.T. is questionable, and research on a larger scale should be implemented to further examine the validity of the D.O.T.

The development of a maternal satisfaction scale for caesarean section.

Satisfaction has become an important outcome measure. The purpose of this study was to develop a valid, reliable maternal satisfaction scale for women undergoing caesarean section. After Research Ethics Board approval, each patient gave verbal consent. To ensure face validity, patients were interviewed before and after caesarean section. Interviewing until no new items were generated ensured content validity. A draft scale using a 7 point Likert scale was given to 115 patients. Items endorsed by less than 15% of patients were deleted. Item-total correlations, principal component and factor analysis were performed and items in factors with less than three items or complex loadings excluded. Correlating the new scale to a Visual Analogue Scale (VAS) for satisfaction assessed construct validity. Reliability, as measured by internal consistency, was tested using Cronbach's alpha. Twenty-five women were interviewed for item generation. Patients were both nulliparous and multiparous and all received regional anaesthesia for elective or non-emergent caesarean section. Six items of the 33 on the draft scale were excluded because of lack of endorsement. Five items were excluded after principal component and factor analysis and two after item-total correlations. The correlation between the scale total and the VAS was 0.48. Cronbach's alpha was 0.82 for the total scale. Maternal sense of control was the item most related to satisfaction. This scale provides more detailed information than a simple VAS. In the population studied, this tool was found to be a valid and reliable method for assessing maternal satisfaction in women undergoing non-emergent caesarean section.

Transcranial Photobiomodulation Variables Assessment Battery: Development and Validation.

Transcranial photobiomodulation (tPBM) response variability is partly driven by biophysical characteristics such as skin tone and hair properties that attenuate photon penetration, and by lifestyle factors including sleep quality, alcohol use, and nicotine consumption that disrupt the mitochondrial and vascular pathways on which tPBM acts. To date, no validated self-report tool exists to capture these moderators systematically. To address this gap, the tPBM Variables Assessment Battery was developed and psychometrically evaluated. It integrates adapted versions of established measures (Brief Pittsburgh Sleep Quality Index, E-cigarette Dependence Scale, Hair Scale Assessment PRO, Monk Skin Tone Scale, and Heaviness of Smoking Index), validated wellbeing evaluators (Ryff's Psychological Wellbeing), and custom measures (Hairstyle Classification, Hair Color Classification). Face and content validity met recommended expert thresholds, internal consistency was acceptable across adapted subscales, and criterion validity analyses confirmed meaningful associations between the lifestyle components and PROMIS-10 global health outcomes. The battery is low-burden, digitally deployable, and psychometrically defensible, offering a practical tool for characterizing the variables most likely to moderate tPBM response in home-use studies.

The validity and reliability of the Knowledge of Women's Issues and Epilepsy (KOWIE) Questionnaires I and II.

The Knowledge of Women's Issues in Epilepsy (KOWIE) Questionnaires I and II were developed to assess what women with epilepsy (WWE) and practitioners know about relevant topics and concerns. Prior to disseminating any tool, an instrument should be both valid and reliable. The purpose of this study was to report the validity and reliability of the KOWIE Questionnaires I and II. To establish validity, the original KOWIE was sent to five experts who critiqued the relevance of each item. A content validity inventory (CVI) was developed later and sent to 20 additional epilepsy experts across the country. Tool stability was evaluated by test-retest procedures. Patients and practitioners completed corresponding tools on day one, and 24 hours later, on day two. Participants were asked to not review information on the topic of interest until after study procedures were completed. Sixteen of 20 expert responses were included in data analysis; 4 were excluded due to incomplete data. The CVI correlation coefficient was 0.92. Test-retest results from all 9 patients and 18 of 20 healthcare professionals were included in data analysis. Correlation coefficients were 0.88 and 0.83 for the KOWIE I and II, respectively, confirming these questionnaires are valid and reliable. While future knowledge may require altering both tools, the current instrument may be used as an assessment tool and guide intervention as it pertains to outcomes in WWE.

A critical review of published competency-to-confess measures.

The development of standardized assessments for competency-to-confess evaluations has remained largely neglected for the last several decades. Groundbreaking research was conducted on Miranda waivers during the late 1970s, but researchers have failed to sustain programmatic research. This critical review focuses on four published Miranda measures (Comprehension of Miranda Rights, Comprehension of Miranda Rights-Recognition, Comprehension of Miranda Vocabulary, and Function of Rights in Interrogation). When evaluated by contemporary standards, the validation of these measures is very limited. Major improvements are needed for interrater reliability, test-retest reliability, content validity, construct validity, and criterion-related validity.

Psychometric properties of Aquarel. a disease-specific quality of life questionnaire for pacemaker patients.

In cardiac pacing current clinical practice permits the use of ventricular or atrioventricular-synchronous pacemakers. However, it is not known which type of pacemaker results in superior clinical and patient outcomes. To date, there is no feasible and validated disease-specific questionnaire for pacemaker patients to assess quality of life (QoL) available. The Aquarel questionnaire was developed as a disease-specific extension to the Short-Form-36 (SF-36). A cross-sectional study was carried out in 74 pacemaker patients to evaluate validity and reliability of this instrument. Items were selected and scales constructed based on factorial analysis. Internal consistency, content validity and test-retest reliability were moderate to excellent. Correlations with the SF-36 scales, pacing mode and functional tests were as hypothesized, demonstrating the individual value and distinctiveness of the Aquarel subscales. The results support the feasibility and usefulness of evaluating QoL in pacemaker patients when using Aquarel as an extension to the SF-36.

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.

Self-defense and martial arts evaluation for college women: preliminary validation of perceptions of dangerous situations scale.

Martial arts and self-defense programs train fearful people, especially women, to be more competent and confident to defend themselves in dangerous situations. However, there are no validated instruments to evaluate the effectiveness of programs purporting to teach self-protection. The Perceptions of Dangerous Situations Scale (PDSS), composed of fear, likelihood and confidence subscales, was developed and validated for university women. Participants were 368 university women, ages 17 to 45 years (M age = 20.7 years). Content validity of the PDSS was established through an expert panel, and construct validity was established through principal components analysis and determination of instructional sensitivity. Reliability was established through alpha coefficients. The PDSS, when used with university women, offers promising measurement opportunities in self-defense and martial arts settings.

Guidelines for developing, evaluating, and revising the classification of personality disorders.

The authors suggest ways to improve the classification of personality disorders by changing the way the classification is developed, evaluated, and modified. Specific proposals are intended to establish a system that can be evaluated and revised so that it successively approximates a valid system. The importance of stating the principles underlying the classification is emphasized. These principles include: the conception of personality disorder underlying each diagnosis, the structure used to define diagnoses, the nature of diagnostic items, and the model for organizing diagnostic decisions. A distinction is drawn among the theoretical, measurement, and diagnostic models underlying each diagnosis. The substantive aspects of the classification are discussed in terms of the evidence required to validate diagnostic concepts. It is argued that the first step in developing a classification is to ensure the content validity of diagnostic concepts because this is a prerequisite for other components of validity. Evaluation and revision of the classification are discussed in terms of the importance of convergent and discriminant evidence. It is recommended that the classification be evaluated and revised using criteria derived from the theoretical and measurement models associated with each diagnosis. It is also recommended that the classification be evaluated in terms of the degree to which diagnostic constructs are consistent across clinicians, different sets of diagnostic exemplars, and different samples of patients. Realization of these aims should provide a classification that may be verified, modified, or disproved in the scientific tradition.

The development of a cognitive scale for functional bowel disorders.

OBJECTIVE: The importance of psychosocial factors in patients with Functional Bowel Disorders (FBD) has been well-established. However, most psychosocial measures used in research with FBD patients were not designed or validated on this population. A recent international team report recommended that psychosocial measures be developed to increase our understanding and treatment of FBD. The purpose of this study was to develop a reliable and valid instrument designed specifically to assess cognitions of patients with FBD. METHOD: An initial set of 204 scale items was generated from a large pool of thought diaries from patients diagnosed with FBD. Items were additionally refined using several methods, including consultation with a multidisciplinary team of international experts on FBD. The remaining 95 items were administered, along with a set of validating questionnaires, to a new sample of 75 FBD patients in Canada and the United States. RESULTS: The findings indicate that the final 25-item scale has high reliability (Cronbach's alpha = .93; inter-item correlation = .36); high concurrent criterion validity evidenced by the correlation of the scale with a global rating of life interference caused by bowel symptoms (r = .71; p<.001); acceptable convergent validity evidenced by the correlation of the scale with the Dysfunctional Attitudes Scale (r = .38; p<.01); high content validity and face validity; and minimal social desirability contamination (r = .15; NS). CONCLUSIONS: The Cognitive Scale for Functional Bowel Disorders is a valid and reliable scale that can be used as an outcome measure in evaluating the efficacy of different forms of psychotherapeutic intervention for FBD, and can also serve as a helpful assessment tool for health professionals working with patients diagnosed with FBD.

Classification of nursing interventions for care of the integument.

The Classification of Nursing Interventions research team at The University of Iowa, College of Nursing is building a taxonomy of nursing interventions that will include all of the direct care treatment activities that nurses perform on behalf of patients. This report describes the study in which 12 nursing interventions and their associated activities for care of the integument were extracted from a large database and validated through a two-round Delphi survey. Using an adaptation of Fehring's model for determining diagnostic content validity of nursing diagnoses, a definition, critical activities, and supporting activities were developed for each of the following interventions: Bathing, Bedrest Care, Hair Care, Nail Care, Oral Health Maintenance, Oral Health Promotion, Oral Health Restoration, Positioning, Pressure Management, Skin Care--Topical Treatments, Skin Surveillance, and Wound Care. Further research is needed to validate supporting activities and to continue classifying interventions and activities that nurses use in treating impaired skin integrity (potential and actual) and altered oral mucous membrane integrity (potential and actual).

An instrument for assessment of subjective visual disability in cataract patients.

AIMS/BACKGROUND: The construction and validation of an instrument for the assessment of subjective visual disability in the cataract patient is described. This instrument is specifically designed for measuring the outcome of cataract surgery with respect to visual disability. METHODS: Visually related activities thought to be affected by cataract were considered for the questionnaire. These were reduced by pilot study and principal components analysis to 18 items. A patient's assessment of his/her ability to perform each task was scored on a four point scale. Scores were averaged to create an overall index of visual disability, as well as subscale indices for mobility related disability, distance/lighting/reading related disability, and near and related tasks visual disability. The questionnaire, administered verbally is entitled "The Visual Disability Assessment (VDA)". Reliability testing included test-retest reliability, interobserver reliability (p, the intraclass correlation coefficient), and internal consistency reliability (Cronbach's alpha). Construct validation, the process for proving that a test measures what it is supposed to measure, included consideration of content validity, comparison with the established Activities of Daily Vision Scale (ADVS) and empirical support with factor analysis. RESULTS: For the four indices, interobserver reliability varied from 0.92 to 0.94, test-retest reliability varied from 0.96 to 0.98, and internal consistency reliability varied from 0.80 to 0.93. The VDA compared favourably with the ADVS by correlation, but Bland-Altman analysis demonstrated that the two instruments were not clinically interchangeable. Factor analysis suggests that all test items measure a common theme, and the subgroupings reflect common themes. CONCLUSIONS: The VDA is easy to administer because it has a short test time and scoring is straightforward. It has excellent interobserver, test-retest, and internal consistency reliability, and compares favourably with the ADVS, another test of visual disability. Factor analysis demonstrated that the 18 items measure a related theme, which can be assumed to be visual disability. The VDA is a valid instrument which provides a comprehensive assessment of visual disability in cataract patients and is designed to detect changes within a patient over time.

[The total laryngectomy patient: validation of the defining characteristics for the nursing diagnosis of "hindered communication"].

This study aimed at validating the defining characteristics of the nursing diagnosis "hindered communication" for patients submitted to total laryngectomy. The diagnostic content validation model (DCV) proposed by FEHRING (1986, 1987) was used. Data were collected by means of a Likert-type frequency scale consisting of twenty-six defining characteristics from the list of the North American Nursing Diagnosis Association (NANDA) and three fictional defining characteristics. Twenty-six clinical and faculty nurses participated in the study. The results showed a total DCV of 0.84 for larger defining characteristics and a total DCV of 0.69 for smaller defining characteristics. It was recognized that the study validated the defining characteristics preconized by NANDA for the nursing diagnosis "hindered communication".

Development of the sleep quality scale.

Sleep quality affects health and the overall quality of life. As the factors that influence sleep quality and their relative importance vary among individuals, a self-report method is essential. Although various questionnaires have been used to assess sleep quality, few all-inclusive assessment scales have been developed. Therefore, the purpose of this study was to develop an instrument for measuring sleep quality and to study its validity and reliability. A Sleep Quality Scale (SQS) was developed using item analysis and factor analysis on items with content validity. SQS, composed of 28 items and six factors, accounted for 62.6% of the total variance. The difference of SQS score between insomniacs and normal subjects confirmed the construct validity (t = -13.8, P = 0.000). Concurrent validity was identified by the significant correlation of SQS with the Pittsburgh Sleep Quality Index (r = 0.72, P = 0.000). The Cronbach's alpha coefficient was 0.92 for internal consistency and the correlation coefficient was 0.81 for test-retest reliability at a 2-week interval. The developed SQS was therefore confirmed to be a valid and reliable instrument for the comprehensive assessment of sleep quality.

Measuring parent satisfaction with a neonatal hearing screening program.

The primary aim of the present study was to investigate parent satisfaction with a neonatal hearing screening program through use of a valid and reliable questionnaire developed for this purpose (Parent Satisfaction Questionnaire with Neonatal Hearing Screening Program; PSQ-NHSP). Eighty parents whose children had received hearing screening participated in this study. High levels of satisfaction were reported with more than 90% of parents satisfied with all aspects of the program.The PSQ-NHSP was analyzed for validity and reliability and demonstrated excellent internal consistency reliability (sigma = 0.94) and excellent test-retest reliability (p = 0.97). Content validity of the PSQ-NHSP was partially established by reviewing available literature on parent satisfaction studies in other pediatric health-care service programs. Construct validity of the PSQ-NHSP was indicated by a significant positive relationship between overall satisfaction and the three specific dimensions in the questionnaire. The satisfaction questionnaire was found to be a useful instrument for identifying service shortfalls, and routine use of the PSQ-NHSP in other neonatal hearing screening programs is recommended.

[Elaboration and validation of an index for preeclampsia diagnosis].

OBJECTIVE: To build a consistent and valid preeclampsia diagnosis index (IDP) for its Spanish acronyms. PATIENTS AND METHOD: The study was done in a Gyneco-Obstetrics Hospital and a Family Medicine Unit from March 2000 to February 2001. Fifty items were chosen from the literature, with a design to validate diagnostic tests, which were assessed by family doctors and gyneco-obstetricians in regard to their appearance and content validity. Concurrent criterion validity. Golden standard: Two gyneco-obstetricians diagnosed pre-eclampsia (hypertension and proteinuria). Simultaneously a family doctor (in an independent and blinded way) questioned, examined and recorded laboratory data of 219 preeclamptic patients and 251 non preeclamptic patients. RESULTS: Preeclampsia diagnosis index is an additive index with 21 clinical and paraclinical parameters weighted according to their individual diagnostic capacity. It has two parts: The first one with 82% (95%CI 80-84) sensitivity; 93% (95%CI 91-95) specificity; the second one with 86% (95%CI 83-89) sensitivity; 75% (95%CI 65-85) specificity. CONCLUSIONS: Preeclampsia diagnosis index is easily applied and has immediate results, which makes easier the physician's decisions.
