Psychometric Evaluation of the ACHIEVE Assessment.

ABSTRACT: Objective: There has been a significant change within clinical practice in childhood disability from "treating" at the level of body function to ecological approaches that address the child's involvement in everyday life. Clinical assessment, and robust tools to support this, are of key importance. The aim of this study was to assess the psychometric properties of the ACHIEVE Assessment in a clinical dataset. The ACHIEVE assessment is a parent and teacher report of participation in home, school and community settings, important contributory factors for participation, and environmental factors. Design: ACHIEVE scores of children were collected from parents and teachers. The Rasch Rating Scale Model produced model estimates with WINSTEPS software. Setting: Clinical rehabilitation settings in Scotland (United Kingdom). Subjects: 401 parents and 335 teachers of 402 children participated resulting in a final sample of 736 responses. Children (78% male) were 4-17 years old (mean 7.91 years SD 2.61). Children had a range of disabilities including Developmental Coordination Disorder, Autism Spectrum Disorder, and Attention Deficit Hyperactivity Disorder. Results: The study includes a large clinical sample of children with disabilities. The results demonstrate that the ACHIEVE Assessment can provide unidimensional measurements of children's participation and important contributory factors for participation. Differential item functioning analysis indicated majority of items were comparable between parent and teacher report. Conclusions: The results confirm evidence of appropriate psychometric properties of the ACHIEVE Assessment. ACHIEVE is a comprehensive tool that enables identification of patterns and issues around participation for clinical and research purposes.

Project description:BackgroundBack pain is an important public health problem and the leading cause of adult disability worldwide and is rising among schoolchildren populations. Despite numerous studies reporting on back care interventions in pediatric population; there is currently no existing theory-based instrument to assess impact and outcome of these programs. This paper reports on development and psychometric testing of a theory based back-care behavior instrument for use among elementary schoolchildren.MethodsThis was a three-phases study that included the following steps: a) a literature research to review existing instruments that assess healthy spine-related behavior in elementary schoolchildren; b) development of a new instrument namely the Back-care Behavior Assessment Questionnaire (BABAQ) based on the Social Cognitive Theory and existing instruments, and c) conducting a cross sectional study to test psychometric properties of the BABAQ by estimating the content validity ratio (CVR), the content validity index (CVI), performing confirmatory factor analysis (CFA), reliability analysis, and convergent validity as estimated by the Average Variance Extracted (AVE).ResultsFirst, a questionnaire (the BABAQ) was developed. It contained of 49 items tapping into 5 pre-defined constructs (skills, knowledge, self-efficacy, expectation beliefs, and behavior). Then, 610 fifth-grade female schoolchildren were entered into a cross sectional study and they completed the BABAQ. The CVR and the CVI of the questionnaire was found to be ≥0.54 and > 0.7, respectively. The CFA confirmed the five constructs and showed good fit for the data. The intraclass correlation (ICC) and the Cronbach's alpha coefficients for the BABAQ were 0.84 (P < 0.001) and 0.93, respectively. The convergent validity as measured by the AVE also showed satisfactory results.ConclusionThe findings suggest that the Back-care Behavior Assessment Questionnaire (BABAQ) is a valid instrument for measuring healthy spine-related behaviors among schoolchildren.

Project description:BackgroundPatient-reported outcome (PRO) instruments provide robust and effective means of evaluating patients' treatment experience; however, none adequately cover experience using self-injection devices with enhanced features, such as an electromechanical autoinjector (e-Device). The aim of this study was to develop a PRO instrument that accurately assesses patient experience of using an e-Device and to evaluate its psychometric properties.MethodsA mixed-methods approach was taken; two parallel, targeted literature reviews were conducted to identify relevant concepts and existing self-injection PRO instruments that could be adapted. Patient feedback obtained from two focus groups was used to inform initial instrument development. The pilot instrument was then administered in a multicenter, open-label, phase 3 clinical study in which patients self-injected certolizumab pegol using an e-Device, to gather evidence of its psychometric qualities. Exit interviews were conducted with a sub-sample of patients enrolled in the study to confirm the appropriateness and clarity of the items included and cognitively debrief the instrument. Confirmatory factor analysis (CFA) was conducted on all items, and each domain's internal consistency was measured using Cronbach's ɑ.ResultsThe literature searches identified several e-Device-specific concepts related to device features, device function, side effects/reactions/pain, confidence, and interference/convenience in daily life. Seven existing PRO instruments were identified. The Self-Injection Assessment Questionnaire (SIAQ), containing pre- and post-injection questionnaire modules, was selected as most suitable and adapted using feedback from 19 patients in the two focus groups to form the pilot Assessment of Self-Injection (ASI) questionnaire. CFA resulted in some changes to the grouping of items in the post-injection module domains following psychometric evaluation of the ASI. Internal consistency was satisfactory for all pre- and post-injection domains (ɑ > 0.8). Cognitive debriefing results from 12 patient exit interviews confirmed the ASI's appropriateness and clarity.ConclusionsThe ASI was developed iteratively with patient input and was evaluated in its intended clinical context of use. Psychometric analyses indicated promising cross-sectional results; the ASI was well understood and considered relevant by patients self-injecting using the e-Device, suggesting that it could be used in real-world settings to aid with clinical decision making.Trial registrationNCT03357471.

Project description:BackgroundThere are no clinical outcome assessment (COA) tools developed in accordance with Food and Drug Administration (FDA) guidance suitable for the evaluation of symptoms associated with respiratory syncytial virus (RSV) infection among infants. The Gilead RSV Caregiver Diary (GRCD) is being developed to fulfill this need; the present research evaluates the GRCD and documents its reliability, validity, and responsiveness among children < 24 months of age with acute RSV infection.MethodsA prospective, observational study was conducted in the United States during the 2014-2015 northern hemisphere winter season. Subjects were < 24-month, full-term, previously healthy infants with confirmed RSV infection and ≤5 days of symptoms. The GRCD was completed twice daily for 14 days by caregivers. Additional data were collected during the initial visit, subsequent visits, and end-of-study interview. Test-retest reliability (kappa and intraclass correlation coefficients [ICCs]), construct validity (correlations and factor analyses), discriminating ability (analyses of variance and chi-square), and responsiveness (effect sizes and standardized response means) were evaluated.ResultsA total of 103 subjects were enrolled (mean age 7.4 ± 5.3 months). GRCD items were grouped into different subscales according to question content, which, with the exception of the behavior impact domain (ICC = 0.43), demonstrated internal consistency (alphas = 0.78-0.94) and test-retest reliability (ICCs = 0.77-0.94). Hypothesized correlations with parent global ratings of RSV severity ranged from 0.45 to 0.70 and provided support for construct validity. Support for discriminating ability was limited. Effect sizes ranged from - 1.48 to - 4.40, indicating the GRCD was responsive to change.ConclusionsThese psychometric analyses support the validity, reliability, and responsiveness of the GRCD for assessing RSV symptoms in children < 24 months of age.

Project description:BackgroundAlthough a wide range of needs assessment tools for cancer patients have been developed, no standardized and commonly accepted instruments were recommended to use in clinical care. This systematic review was conducted to assess the quality of psychometric properties of needs assessment tools among cancer patients in order to help oncology healthcare professionals select the most appropriate needs assessment tools in routine clinical practice.MethodsSearches were conducted in the electronic databases of PUBMED from 1966, CINAHL from 1960, EMBASE from 1980 and PsychINFO from 1967 as well as additional sources. The quality of psychometric properties of the recruited needs assessment tools was evaluated using the agreed quality criteria for measurement properties of health status questionnaires.ResultsThirty-seven studies which evaluated the psychometric properties of 20 needs assessment tools were identified. Internal consistency was tested in 32 studies with 9 studies indicating negative rating and 4 studies intermediate rating. Less than half of the studies (13 studies) assessed test-retest reliability, and only 4 studies reported positive rating. Content validity was the most tested psychometric property appraised in 33 studies and indicated positive rating in all the evaluated studies. Structural validity was adequately evaluated in 28 studies with 23 studies reporting intermediate rating. More than half of the studies (29 studies) tested hypothesis testing and 13 studies were rated positive. Cross-cultural validity results were obtained in 13 studies with 7 studies showing negative rating. No data was available on measurement error and criterion validity. Only one study appraised responsiveness and showed intermediate rating. The Supportive Care Needs Survey-Short Form (SCNS-SF) is the most widely used instrument for needs assessment in cancer patients. It had strong evidence for internal consistency, content validity, structural validity and hypothesis testing, and moderate evidence for reliability and cross-cultural validity. Cancer Survivors' Unmet Needs Measure (CaSUN) reported strong or moderate evidence for internal consistency, reliability, content and structural validity, and hypothesis testing. Furthermore, Supportive Cancer Care Needs Assessment Tool for Indigenous People (SCNAT-IP) had strong evidence for content validity, and moderate evidence for internal consistency, structural validity and hypothesis testing.ConclusionsDespite several needs assessment tools exist to assess care needs in cancer patients, further improvement of already existing and promising instruments is recommended.

Project description:BACKGROUND:Although cervical cancer is ??the second most common tumor among Brazilian women, studies that evaluate the quality of life of these women are still scarce. This situation is explained by the lack of specific and validated tools for this purpose in Portuguese (Brazil). The aim of this study was to evaluate the psychometric properties of the Portuguese version of the FACT-CX (Functional Assessment of Cancer Therapy-Cervix) questionnaire in a population of Brazilian women with cervical cancer. METHODS:The psychometric properties of the FACT-CX questionnaire were tested in a sample of 100 women diagnosed with cervical cancer who were previously treated in the Barretos Cancer Hospital. We analyzed the internal consistency (Cronbach's alpha), reproducibility (intraclass correlation coefficient--ICC), confirmatory factor analysis, convergent validity (correlation with the SF-36 questionnaire), and discriminant validity by disease stage and two questions related to self-perception of health was also performed. RESULTS:The scales had Cronbach's alpha coefficients ranging from 0.61 to 0.80. However, three scales did not have a statistically significant coefficient greater than 0.70. The ICC ranged from 0.68 to 0.82 and all considered satisfactory. Factor analysis did not generate consistent components. The FACT-G and FACT-CX total scores had good internal consistency and reproducibility, and also correlated well with the General Health and Vitality scales of the SF-36. However, only two FACT-CX scales had a significant correlation with SF-36. Discriminant analysis showed that FACT-CX failed to discriminate groups according to clinical stage but was able to divide the women according to the self-perception of health. CONCLUSION:FATC-CX total score had good internal consistency, reproducibility and discriminant validity. In addition, it correlated well with General Health and Vitality scales of SF-36. However, three scales had questionable internal consistency and only two had significant correlation with SF-36.
