Use of the Clark-Madison Test of Oral Language with the hearing-impaired: a content validity and comparative study.

This study examined the content validity of the Clark-Madison Test of Oral Language (CMTOL) as a measure of nonwritten expressive language with hearing-impaired children. Twenty severely hearing-impaired children were administered the CMTOL using total communication. All test administrations were considered valid. The content of the test was generally found to be valid. The content validity of selected items is discussed. A comparison of the performance of the hearing-impaired to a group of normal-hearing respondents revealed a different profile of strengths and weaknesses than did intragroup analysis.

Teaching Engagement and Caregiving Help in the Intensive Care Unit (TEACH-ICU) Scale: Content Validity.

BACKGROUND: Having family members provide care to their loved ones in the intensive care unit (ICU) is a beneficial yet seldom implemented approach. For family members to perform caregiving, nurses must be willing to teach, and such willingness is a developing area of research. OBJECTIVES: To adapt an instrument validated in family members, the Family Willingness for Caregiving Scale, to address nurses' willingness to teach family members caregiving skills. METHODS: Purposive and snowball sampling were used to recruit 10 expert ICU nurses through the American Association of Critical-Care Nurses' research website and social media platforms. The researchers conducted cognitive interviews with the nurses to address the instrument's content validity. RESULTS: The scale was refined based on the participants' feedback. Items were deleted, added, and revised. Furthermore, scale instructions were adjusted to emphasize the willingness to teach families of patients receiving mechanical ventilation. Qualitative themes emerged related to barriers to family engagement, including time constraints, patient acuity, and nurse and family characteristics. CONCLUSIONS: Content validity of the scale was assessed, with future research aimed at pilot testing and evaluating construct validity before using the scale as a research instrument. Practical implications include using the scale as an evaluation tool to determine nurses' willingness to teach family members about caregiving. After evaluation, various strategies could be incorporated to enhance family engagement in adult ICUs.

Content validity, face validity and comprehensiveness of generic quality-of-life measures in adults and children with rare genetic conditions and their carers: a think aloud qualitative study.

PURPOSE: This study aims to assess the content validity, face validity and comprehensiveness of the: (a) EQ-5D-5L, EQ-HWB, and ASCOT SCT4, for adults with rare genetic conditions; (b) the EQ-5D-5L, EQ-HWB, and ASCOT-carer for carers of adults or children with rare genetic conditions; and (c) the EQ-5D-Y-5L carer proxy-complete for children with rare genetic conditions. METHODS: In total, 60 qualitative think-aloud interviews were conducted in Australia and England to understand individuals' thought process during the completion of the QoL measures. Participants were subsequently led through a semi-structured discussion. Transcripts were analysed for whether participants demonstrated understanding of the measures and thematic analysis was conducted on responses to the semi-structured discussion. RESULTS: The majority of participants showed good understanding and supported the validity of the measures for people experiencing rare conditions. For carers, however, a broader evaluative space than health-related QoL was preferred. Several non-health domains were identified as important to both patients and carers, including treatment availability, impact on employment and finance, information and uncertainty, medication and carer burden, impact of passing on a condition, relationships and social connection, and experience with the healthcare system. CONCLUSION: This study provides some support for the face validity and comprehensiveness of the measures for people experiencing rare conditions. However, several participants felt that the narrow health domains were inadequate to capture the breadth of their lived experience. Future research should explore the extent to which the measures capture differences and changes in the QoL domains identified as important to patients and carers.

Healthcare needs scale for patients with HIV/AIDS: content validation.

The authors of this study adapted Peters' (1987) community health specifications of patients' nursing requirements so they could be applied to patients with HIV/AIDS in hospital, dedicated outpatient HIV clinic, home care, and long-term care settings. The authors then collected validity evidence on the revised specifications, developed a sample of 62 multiple-choice items, and obtained content-related validity evidence via a judgmental review panel. The results produced: (a) a set of specifications for the environmental, psychosocial, physiological, and health behaviors domains; and (b) a 44-item scale of patient characteristics related to four levels of healthcare needs.

Patient-reported outcome measures for depression or anxiety symptoms in patients with cardiovascular disease: A COSMIN systematic review.

BACKGROUND: Depression and anxiety are common in patients with cardiovascular disease (CVD), but the measurement quality of patient-reported outcome measures (PROMs) used in this population remains unclear. This review aimed to evaluate the methodological quality, measurement properties, and certainty of evidence for depression and anxiety PROMs in adults with CVD and to inform instrument selection. METHODS: Following COSMIN and PRISMA guidance, four databases were searched from inception to February 2026. Studies assessing measurement properties of PROMs in adults with CVD were included. Methodological quality was evaluated using the COSMIN Risk of Bias checklist, and certainty of evidence was graded using an adapted GRADE approach. RESULTS: Sixty-six studies assessing 38 PROMs were included, comprising 29 generic and 9 CVD-specific instruments. Six PROMs met COSMIN Category A criteria: Cardiac Depression Scale-Short Form, Patient Health Questionnaire-9, Beck Depression Inventory-II, Hospital Anxiety and Depression Scale, Generalized Anxiety Disorder-7, and Major Depression Inventory. Four instruments were classified as Category C because of insufficient structural validity. Content-validity evidence was largely indeterminate or of limited certainty. Only 24 studies used confirmatory factor analysis or Rasch analysis, and no study assessed measurement error or responsiveness. Cross-cultural validity evidence was scarce. CONCLUSIONS: Six PROMs met Category A criteria, but selection should remain purpose- and context-specific. Particular attention should be given to somatic symptom overlap and intended clinical use. Further validation should prioritize content validity, measurement invariance, responsiveness, measurement error, and clinimetric performance.

Critical insights on the application of the theory of planned behaviour to food handlers' food safety practices.

Foodborne diseases remain a significant public health concern, often linked to unsafe food-handling practices. The Theory of Planned Behaviour (TPB) is widely used to predict and explain food safety behaviours, yet its application in this field has not been systematically and in-depth evaluated. This review evaluated how the TPB has been applied to study food handlers' behaviour, focusing on methodological approaches, use of the TACT (Target, Action, Context, and Time) framework, validity, elicitation studies, and reliability. Seventeen studies were included following a systematic search of four databases (Scopus, Web of Science, Wiley Online Library, and Taylor & Francis Online). Data were extracted on behaviour definition, aim of study, main findings, use of indirect and direct TPB measures, use of elicitation studies, internal consistency, content validation, analytical methods used, and any extensions to the original TPB framework. Key elements related to adherence to core TPB principles and measurement practices were extracted using a Checklist. Most studies used direct measures of TPB constructs, and only a few reported procedures for content validation. Considerable variability was found in the reporting of key measurement and psychometric practices. Five studies fully applied the TACT framework, while nine incorporated additional factors such as knowledge and moral norms. Elicitation studies were conducted in five cases where indirect measures were employed. Analytical approaches were mainly based on multiple linear regression, with limited use of more advanced techniques such as structural equation modeling. Twelve studies reported internal consistency results. Overall, the review highlights opportunities to strengthen methodological practices in future TPB research on food safety. Greater attention to conducting and reporting content validation, full application of the TACT framework, reporting of internal consistency, and consistent inclusion of elicitation studies when using indirect measures may enhance transparency, reinforcing the credibility and trustworthiness of research findings. A major methodological limitation of this review was that screening and data extraction were conducted by a single reviewer and no formal quality or risk-of-bias assessment of the included studies was performed. Despite these limitations, the findings provide practical guidance for the development and validation of TPB-based questionnaires and may support more robust food safety research, interventions, and policy initiatives aimed at improving food handlers' practices.

Measurement of safe sex behavior in adolescents and young adults.

The aim of this project was to develop an instrument to measure use of safe sex practices among adolescents and to conduct initial evaluation of the psychometric properties of the instrument. The Safe Sex Behavior Questionnaire (SSBQ) was designed to measure the frequency of use of safe sex practices and was assessed for content validity, reliability, and construct validity through a series of tests. The content validity index computed for the SSBQ was 98%. Initial reliability computed for sums of items of the total scale was .82 among 89 college freshmen. Using a second sample of 531 subjects, the SSBQ was factor-analyzed separately for males and females and five similar factors emerged for each gender. Reliability coefficients for sums of salient items for each factor ranged from .52 to .85. Using a third sample of 174 subjects, construct validity was assessed by correlating the SSBQ with measures of general assertiveness and general risk-taking. The resulting correlations were appreciable and in the predicted directions, thus providing support for the construct validity of the instrument.

Faculty and student perceptions of effective classroom teaching in nursing.

The purpose of this three-stage study was to identify and validate constructs which students use in differentiating among teachers. In stage I, six theoretical constructs thought to be involved in teaching effectiveness were identified; these were revised through a faculty content validity study. In stage II, a known-groups validity study, all items and constructs were found to be used by students in differentiating between good and poor teachers. In stage III, students' ratings of current teachers were collected and factor analyzed. Two factors, individualized prescriptive approach and systematic theoretical presentation, were identified. An analogy was drawn between these factors and elements of nursing process. The category structure which had been derived through the faculty content validity study was not supported.

Validating the content of pediatric outpatient medical records by means of tape-recording doctor-patient encounters.

Information in 51 tape-recorded physician-patient encounters was compared with information written in the patients' medical records. Diagnoses, chief complaints, scheduled appointments, non-drug therapy, and diagnostic studies were uniformly well-recorded. Medication names were well-recorded but dosages were not. Characteristics of care such as levels of function, probable cause of illness, reason for follow-up, and compliance were recorded poorly. Patients were more likely to known about and understand their diagnosis, and names, dosage, and intended function of their medications when this information was written in the record than when it was not. These findings indicate a relationship between the quality of medical records and the effectiveness of care.

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.

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.

An instrument for measuring cancer patients' preferences for support groups.

The purpose of this study was to develop a valid and reliable instrument to assess cancer patients' preferences for all types of social support and organizational features of cancer support groups. The content of the instrument was the result of a detailed analysis of four resources: (1) literature relating to cancer support group interventions, (2) program materials from existing groups, (3) interviews with individuals who developed or directed groups, and (4) interviews with patients who have participated in cancer support groups. A jury of six experts was used to establish content validity of the instrument. The reliability of the instrument was examined by measuring a sample of 258 cancer patients. The reliability coefficients of the instrument were all above .80, except for two types of social support (instrumental and informational-educational), which were .72 and .78, respectively. It was concluded that the instrument produces valid and reliable measurements of cancer patients' preferences for cancer support groups.

Development of the 'Activities of Daily Vision Scale'. A measure of visual functional status.

To develop a method for the evaluation of visual function in subjects with cataracts, the authors identified 20 visual activities and categorized them into five subscales (distance vision, near vision, glare disability, night driving, and daytime driving) that comprised the Activities of Daily Vision Scale (ADVS). Each subscale in the ADVS was scored between 100 (no visual difficulty) and 0 (inability to perform the activity because of visual difficulty). In 334 subjects scheduled for cataract extraction (mean age 75 +/- 9 years, 67% women), ADVS scores (mean +/- standard deviation) for each subscale ranged from 44 +/- 31 for night driving to 72 +/- 24 for near vision activities. When administered by telephone, inter-rater reliability coefficients (r) were 0.82 to 0.97 (P < 0.001) for each of the subscales, and test-retest reliability was 0.87 for the scale overall. Cronbach's coefficient alpha was very high for both the in-person (alpha = 0.94) and telephone (alpha = 0.91) formats. Criterion validity, the correlation between visual loss and ADVS score, was -0.37 (P < 0.001) when the ADVS was administered in person and -0.39 (P < 0.001) when it was administered by telephone. Content validity as assessed with factor analysis showed that 88% of the variance of the principal components weighted on one factor. The authors conclude that substantial visual disability is not captured by routine visual testing and that the ADVS is a reliable and valid measure of patient's perception of visual functional impairment.

Validity and reliability of the infant behavioral summarized evaluation (IBSE): a rating scale for the assessment of young children with autism and developmental disorders.

The Infant Behavioral Summarized Evaluation (IBSE) is a rating scale adapted from the Behavioral Summarized Evaluation (BSE) and specifically related to the assessment of behaviors of young children having autistic disorders. Content validity and reliability studies described in the paper were made from behavior ratings of videotapes for 89 children aged from 6 to 48 months. Results show a significant group of 19 items including some characteristic early autistic behaviors (communicative and social abnormalities) and some that are less commonly described in the syndrome (attentional, perceptive, and adaptive disorders). The value of the use of this scale for clinicians and professionals involved in behavioral evaluations and treatment of young children with developmental disorders and the necessity for further psychometric investigations are discussed.

Assessing achievement for minimal academic competency. II. Validity and reliability.

Research was undertaken to develop, administer, and evaluate two forms of a criterion-referenced test instrument for measuring the competency status of students graduating from undergraduate programs in general dietetics. Involved in the evaluation of the final forms were 186 students graduating from fourteen college or university programs. Results are reported on the content validity, concurrent validity, reliability, and summary and individual test-item statistics. It is concluded that the test forms need further refinement and development and that the use of criterion-referenced evaluation tools to measure academic competency of students graduating in dietetics is needed.

[French-language adaptation of an evaluation test of knowledge meant for insulin-dependent children: methodology and value for research in clinical practice].

A measure of knowledge level of diabetic patients is useful in evaluating their educational needs as well as the impact of the educational programs specifically designed for them. The lack of such scales in French, led us to translate and validate an existing knowledge scale for diabetic children, the Test of Diabetes Knowledge (TDK) (Johnson et al.). After several translations and back translations, the 33 item scale was submitted to the staff members of a pediatric diabetology unit, to establish its content validity. An assessment the questionnaire was performed in a group of 49 children, aged 7.9 to 12.8 years. The mean duration of diabetes was 4.6 +/- 2.9 years and their scholastic level varied from 1st to 6th grades. Time spent in filling out the questionnaires was 12 to 25 minutes. Few missing values were noted. The reliability of the scale was excellent as shown by Cronbach's alpha coefficient: 0.83 for the overall scale, 0.72 for the general knowledge subscale (20 items) and 0.70 for the problem solving subscale (13 items). The level of correct responses was correlated with age and scholastic level (p < 0.0001), but not with sex, duration of diabetes, or HbA1c levels. This study shows that the French version of the TDK is a valid and reliable tool for measuring the level of knowledge in children and adolescents with diabetes. This scale provides the researcher and clinician with a tool that facilitates the performance of an educational diagnosis and the evaluation of educational programs based on the transmission knowledge.

Construction and validation of the Alberta Infant Motor Scale (AIMS).

The Alberta Infant Motor Scale (AIMS), an observational assessment scale, was constructed to measure gross motor maturation in infants from birth through independent walking. Based upon the literature, 58 items were generated and organized into four positions: prone, supine, sitting and standing. Each item describes three aspects of motor performance--weight-bearing, posture and antigravity movements. Content validation of the instrument was accomplished through a mail survey of Canadian pediatric physical therapists and consultation with an international panel of experts. Five hundred and six infants, age-stratified from birth through 18 months, participated in the reliability and validity testing of the AIMS. In addition, 20 infants who were experiencing abnormal motor development and 50 infants at risk for motor disorders were assessed and compared with the results of the full-term sample. Results to be presented include: 1) test-retest and inter-rater reliability estimates; 2) correlations between the AIMS and the Bayley and Peabody motor scores; and 3) scaling of the items along the age continuum for normal motor development.

Health status: types of validity and the index of well-being.

The concept of validity as it applies to measures of health and health status is examined in the context of a set of standard, widely accepted definitions of validity. Criterion validity is shown to be irrelevant to health status measures because of the lack of a single specific, directly observable measure of health for use as a criterion. To overcome this problem, the Index of Well-being has been constructed to fulfill the definition of content validity by including all levels of function and symptom/problem complexes, a clearly defined relation to the death state, and consumer ratings of the relative desirability of the function levels. Data from a two-wave household interview survey provide convergent evidence of construct validity by demonstrating an expected positive correlation of the Index of Well-being with self-rated well-being and expected negative correlations with age, number of chronic medical conditions, number of reported symptoms or problems, number of physician contacts, and dysfunctional status. Discriminant evidence of construct validity is demonstrated by predicted differences in correlation between concurrent Index of Well-being scores and self-assessed overall health status, and between the Index of Well-being scores and self-rated well-being on different days. A simple method of estimating a currently usable comprehensive population index of health status, the Weighted Life Expectancy, is described.
