Abstract Background Development is rapid in the first years of life. Developmental delays appearing during this critical period have the potential to persist throughout the child’s life. Available standardized assessments for this age record a child’s ability to successfully complete discrete skills but fail to capture whether the child incorporates those skills into daily routines that are meaningful to the child and family. The Infant Toddler Activity Card Sort (ITACS) is a newly developed photograph-based early intervention tool to measure the participation-related concept of activity competence using caregiver report. The purpose of the present study was to use Rasch analysis to determine if ITACS items comprehensively measure the construct of child activity competence. Results A total of 60 child/caregiver dyads participated. The dichotomous caregiver-reported responses (present vs. absent) on the 40 individual ITACS items were used in Rasch analysis, and three iterations of the model were completed. The final model included 51 child/caregiver dyads and 67 ITACS assessments with a good spread of individual ability measure (6.47 logits). All items demonstrated adequate infit except for “sleeping” (range 0.68–1.54). Five items (sleeping, eating at restaurants, brushing teeth, crawling, and interact with pets) demonstrated high Mean Square (MNSQ) outfit statistics and one (take a bath) demonstrated low MNSQ outfit. ITACS items demonstrated a good spread of item difficulty measures (6.27 logits), and a clear ceiling was observed. Three activity items (smiling, breastfeeding, and playing with adults) were rarely endorsed as concerns. The activities most likely to be reported as challenging were “crying/communicating” and “going to school”. Person and item reliability statistics were adequate (0.79 and 0.80, respectively). The separation between individuals and between items were adequate to good (1.96 and 1.99, respectively). Conclusions Findings indicate that ITACS items are measuring a unidimensional construct--activity competence in early childhood. The Rasch analysis of caregiver responses suggest that some activities are more likely to be considered challenging and may be important targets for intervention. These results provide evidence to further validate the ITACS as a caregiver report measure and support its use in the early intervention setting to facilitate caregiver driven goal development.

Abstract Background The Catquest-9SF questionnaire is a patient reported outcome measure that quantifies the visual benefits from cataract surgery. The purpose of this study was to translate and adapt the Catquest-9SF questionnaire for France, to assess its psychometric properties via Rasch analysis, and to assess its validity when completed using an electronic notepad. Methods The Catquest-9SF questionnaire was translated following the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Catquest-9SF and clinical data were collected from patients before and after routine cataract surgery. All questionnaire data were collected via an electronic notepad. Rasch analysis was performed to assess psychometric properties, and sensitivity to change was analysed for patients with complete paired pre- and post-operative questionnaires. Results A complete filled-in preoperative questionnaire was obtained for 848 patients. Rasch analysis showed good precision (person separation: 2.32, person reliability: 0.84), ordered category probability curves, no item misfit, and unidimensionality. The respondents were slightly more able than the level of item difficulty (targeting: −1.12 logits). Sensitivity was analysed on 211 paired questionnaires, and the postoperative questionnaires showed a clear ceiling effect. The effect size was 2.6. The use of an electronic notepad for completing the questionnaire worked out very well after some adjustments. Conclusions The French version of Catquest-9SF has good psychometric properties and is suitable for use in French-speaking patients. The use of the Catquest-9SF questionnaire in an electronic format showed good validity.

<p>The School Attitude Assessment Survey-Revised (SAAS-R) was developed by McCoach &amp; Siegle (2003b) and validated in Spain by Author (2014) using Classical Test Theory. The objective of the current research is to validate SAAS-R using multidimensional Rasch analysis. Data were collected from 1398 students attending different high schools. Principal Component Analysis supported the multidimensional SAAS-R. The item difficulty and person ability were calibrated along the same latent trait scale. 10 items were removed from the scale due to misfit with the Rasch model. Differential Item Functioning revealed no significant differences across gender for the remaining 25 items. The 7-category rating scale structure did not function well, and the subscale goal valuation obtained low reliability values. The multidimensional Rasch model supported 25 item-scale SAAS-R measures from five latent factors. Therefore, the advantages of multidimensional Rasch analysis are demonstrated in this study.</p>

Rasch modeling was used to examine the 25-item Connor-Davidson Resilience Scale within adults ( n = 410) in a weight management program. Rasch analysis assessed model-data fit, item difficulty and person’s resilience level, an item-person map to evaluate relative distribution items and persons, and rating scale function. Four misfit items were identified and removed. Item difficulty ranged from 1.25 to 1.19 logits (higher logit values indicate more difficult items). Persons’ resilience level had wide distribution (resilience = 2.27 ± 1.56 logits). Item difficulty levels did not adequately assess higher resilience levels. An improved inventory that measures a wider range of resilient behaviors would improve measurement quality.

A validation study the Iranian Modified Barthel Index (MBI) in hospitalized acute stroke elderly by classical test theory approach and investigate Rasch analysis for both Iranian version MBI and BI and compare the hierarchical item difficulty of them. Face-to-face interview with 100 geriatric stroke inpatients 60+ or their caregivers was done in a cross-sectional study. First, construct validity of MBI analyzed by the classical test theory, then Rasch analysis were done for BI and MBI. The reliability of the Iranian MBI was significant at 0.955. One factor achieved by the variance of 83.2%. In Rasch analysis for MBI, the most difficult item was stair climbing, whereas the simplest items were bowel and bladder control. In BI, the most difficult items were toilet use and ambulation. The Iranian MBI is very accurate and reliable; therefore the use of MBI to measure better outcomes in stroke elderly inpatients is recommended comparing with BI.

The 25-item Phlegm Pattern Questionnaire (PPQ) has been widely used to examine the relationship between the phlegm pattern (PP), quality of life, tongue colour, vocal qualities, and dysfunctional breathing. However, the concerns of response burden and differences in the respondent’s abilities or item difficulty for the original version of the PPQ have not been sufficiently addressed. This study aimed to develop a short-form PPQ using Rasch analysis, an item response theory. Based on the retrospective data, the response order, differential item functioning (DIF), dimensionality, reliability, concurrent validity, and fitting errors were examined for 291 normal participants and 61 inpatients. The discriminative ability of the short-form PPQ was examined using receiver operating characteristic curve analysis. Along with Rasch analysis, another short-form PPQ was developed using equidiscriminative item-total correlation (EITC) analysis and the results between the two short-form PPQs were compared accordingly. Rasch analysis results suggested a 6-point response category for the PPQ, and finally, 8 items without fitting errors or DIF variability were selected for the PPQ (PPQ-8). The PPQ-8 had satisfactory reliability (person separation index = 2.23), unidimensionality (unexplained variance in the first contrast = 1.598), fitting levels (infit mean square, 0.80–1.39; outfit mean square, 0.79–1.34), sensitivity (70.5%), and specificity (76.5%). The PPQ-8 had a moderate discriminative ability of the PP (area under the curve = 0.759), and the cut-off point was 23. Although the 8-item PPQ developed using EITC analysis showed similar levels of reliability, validity, and discriminative ability of the PP to the PPQ-8, it could not present the information of item hierarchy and differences in the respondents’ abilities. In conclusion, the PPQ-8 by Rasch analysis is recommended for future use to evaluate the clinical severity of PP.

Early intervention (EI) therapy services aim to address family-centered goals to facilitate young children’s development and participation in meaningful life activities. Current methods to evaluate children in EI assess discrete developmental skills but provide little information on the child’s ability to successfully incorporate that skill in everyday life. Furthermore, traditional measures have limited opportunity for parent report, despite parent engagement being a critical component for successful implementation of EI services. A measure that involves parents in the therapeutic process to track family-driven EI goals related to a child’s occupational engagement in meaningful family activities and routines is desperately needed. Using a qualitative design and conventional content analysis, we identified 41 distinct activities of infant–toddlers from a cohort of 23 caregivers. Activity items were matched with photographs and validated with experts in pediatric rehabilitation using the Delphi method. The resulting 40 activity/photograph pairs were used to develop a new measure of pediatric occupational engagement, the Infant Toddler Activity Card Sort (ITACS).

While it is widely acknowledged that language development is delayed for the majority of individuals with fragile X syndrome (FXS), there has been limited research into how best to assess this area. This study aimed to deepen the understanding of standardized language assessment in FXS by addressing the three following objectives: (1) Examine the feasibility and validity of widely-used, standardized assessments in participants with FXS; (2) describe linguistic and cognitive profiles for a large sample of individuals with FXS; and (3) Compare results obtained from objective testing in clinic to those obtained using caregiver report. Results indicate that previous results indicating strong correlations between cognition and language results hold true across a wide range of ages as well as across multiple assessments, with an exception in very young children. Caregiver report tended to give lower estimates of language ability than what was found using an objectively administered assessment. Appropriate assessments remain difficult to find as a significant percentage of individuals scored at floor when scaled scores were calculated. Further, a sub-group of participants were coded for behavioral response to testing demands, the majority being able to complete a standardized assessment. These results speak to the need for assessments that provide a wider range of items so individuals can both achieve a valid score and demonstrate progress in their attainment of language skills.

Background A paucity of information exists on the psychometric properties of several balance outcome measures. With the exception of the Modified Functional Reach Test, none of these balance outcome measures were developed specifically for the population with spinal cord injury (SCI). A new balance assessment tool for people with SCI, the Activity-based Balance Level Evaluation (ABLE scale), was developed and tested. Objective The purposes of this study were: (1) to develop a scale capturing the wide spectrum of functional ability following SCI and (2) to assess the initial psychometric properties of the scale using a Rasch analysis. Design A methodological research design was used to test the initial psychometric properties of the ABLE scale. Methods The Delphi technique was used to establish the original 28-item ABLE scale. People with SCI at each of 4 centers (n=104) were evaluated using the ABLE scale. A Rasch analysis was conducted to test for targeting, item difficulty, item bias, and unidimensionality. An analysis of variance was completed to test for discriminant validity. Results The Rasch analysis revealed a scale with minimal floor and ceiling effects and a wide range of item difficulty capturing the large scope of functional capacity after SCI. Multiple redundancies of item difficulty were observed. Limitations All raters were experienced physical therapists, which may have skewed the results. The sample size of 104 participants precluded a principal component analysis. Conclusion Development of an all-inclusive clinical instrument assessing balance in the SCI population was accomplished using the Delphi technique. Modifications of the ABLE scale based on the Rasch analysis yielded a 28-item scale with minimal floor or ceiling effects. Larger studies using the revised scale and factor analyses are necessary to establish unidimensionality and reduction of the total item number.
