Data-driven learning is a sub-discipline of corpus linguistics that makes use of the analyses and tools of corpus linguistics in foreign and second language classroom (Johns, 1991; Johns & King, 1991). With this approach, learners become researchers rather than passive recipients of language rules (Johns, 1991). This study was an investigation of the impact of this approach as a form of written corrective feedback for in-service teachers of English participating in an online writing course at a teacher training institute in Japan. Data-driven learning is commonly utilized in conventional, face-to-face classrooms, or computer lab settings in which there is close direction from the instructor on how to interpret the output of a corpus query. The purpose of this study was to investigate how data-driven learning can be implemented in a blended online environment by providing training to develop the participants’ corpus competence (Charles, 2011; Flowerdew, 2010), which is defined as the ability to interpret data obtained from querying a corpus. This competence has been associated with becoming familiar with corpus methods, which include interpreting concordances, and in turn can aid in accurately repairing writing errors. This training, while initially presented in a face-to-face session at the beginning of the course, was sustained with support from resources on the course’s Moodle website and my comments in Microsoft Word documents. In addition, I applied a fine-grained approach to the analysis of the to examine the quality of participants’ interpretation of concordances. The mixed method triangulation convergence design (Creswell & Plano Clark, 2007, 2011) used in this study was based on data from four sources to examine the effectiveness of data-driven learning in an online environment as well as to observe how the participants interpreted concordances. One data set involved an analysis of the participants’ responses in drafts of their own writing to concordance-based feedback. The participants were given a prefabricated concordance, which was a concordance I generated. That concordance was attached to an error in the participants’ document and the participants used the information provided by the concordance to repair their writing error. The resulting data set, which contains the concordance, along with before and after comparisons of the writers’ repairs, shows how the participants’ interpretations of concordances aided the repairs. With the evidence of several trials over the course of four writing assignments, it was possible to see how the participants used the supplied concordance to repair their writing errors and in turn revealed their degree of corpus competence. A second data set obtained from think-aloud protocols from select participants was utilized to reveal how they interpreted the concordance during an error-repair task. This data revealed what kind of thought processes or noticing that occurred in this task. A third piece of evidence was derived from data obtained from the Moodle website via log files and other resources such as online documents and training quizzes. The purpose was to document which resources the participants accessed relating to data-driven learning training to investigate if those resources aided in their development of corpus competence. The fourth piece of evidence was a quiz developed online to compare the participants with a standard set of items. The quiz was used to investigate which participants successfully or unsuccessfully interpreted the concordances. This instrument, which was analyzed with the Rasch model, allowed for further comparison between the participants’ skill of interpreting concordances. These four data sources were triangulated and in the final analysis cross-referenced to examine how data-driven learning can be successfully applied in a blended online learning environment and how the training of corpus competence aided the learners in interpreting the concordances. / Teaching & Learning

Syftet med denna uppsats var att undersöka sociometerteorins sociologiska relevans, förenlighet med flerdimensionella och hierarkiska modeller av självbild samt mätinstrumentet Revised Janis and Field Scales mätegenskaper. En enkät administrerades till 225 studenter vid Karlstads universitet, varav 140 respondenter var kvinnor och 85 var män. Resultatet visar att principiell komponentanalys i huvudsak replikerar valideringsstudien från 1984 medan Raschanalys visar att mätinstrumentet har stora och allvarliga problem och behöver revideras innan användning eller kasseras. Vidare är den modell över självbilden som mätinstrumentet är avsett att fånga föråldrad och inaktuell. Resultatet visar även att sociometerteorin kan relateras till symbolisk interaktionism och därmed har en sociologisk relevans men att förenligheten med modeller över självbilden är begränsad till huruvida teorin kan anses beskriva mekanismen bakom den sociala självbilden. Diskussionen avhandlar självkänslans självuppfyllande profetia, att självhjälpsindustrin, media och allmänhet etiketterar företeelser som och tillskriver begreppet betydelse och relevans varpå det beforskas vidare trots att forskningsfältet verkar befinna sig i ett degenerativt tillstånd. Vidare diskuteras att självkänsla och självbild ej är utbytbara begrepp eftersom det senare begreppet har prediktiv validitet (dvs. har visats förutsäga andra utfall). Slutligen ges ett förslag att antingen rikta fokus mot att studera självmedkänsla, socialt stöd, socialt kapital, självbild och subjektivt välmående istället för det för närvarande fruktlösa självkänslabegreppet, eller att utveckla begreppet teoretiskt innan fler kvantitativa studier utförs. Ytterligare slutsatser och implikationer av uppsatsen diskuteras. / The purpose of this thesis was to investigate the sociometer theory’s sociological relevance, compatibility with multidimensional and hierarchical models of the self-concept and the measurement instrument Revised Janis and Field Scales measurement properties. A questionnaire was administered to 225 students at Karlstad University, of whom 140 respondents were female and 85 were male. The results shows that the principal components analysis in general replicates the validation study from 1984 while Rasch analysis demonstrates that the measurement instrument have major and severe problems and needs to be revised before use or discarded. Furthermore, the model of self-concept that the measurement instrument is intended to capture is outdated and obsolete. The results also shows that the sociometer theory can be related to symbolic interactionism and thus have a sociological relevance but that the compatibility with models of the self-concept is limited to whether the theory can be regarded as describing the mechanism behind the social self-concept. The discussion treats a self-fulfilling prophecy of self-esteem, that the self-help industry, media and public label phenomena as and ascribes the concept meaning and relevance whereon it is further researched despite that the research field seems to be in a degenerative state. Furthermore, self-esteem and self-concept are not interchangeable concepts since the latter concept has predictive validity (i.e. has been shown to predict other outcomes). Finally, a proposition is made to either direct focus at researching self-compassion, social support, social capital, self-concept and subjective well-being instead of the currently fruitless self-esteem concept, or to develop the concept theoretically before conducting more quantitative studies. Further conclusions and implications of the thesis are discussed.

This study investigated the difficulty order of 38 grammar structures obtained from an analysis of multiple-choice items using a Rasch analysis. The order was compared with the order predicted by processability theory and the order in which the structures appear in junior and senior high school textbooks in Japan. Because processability theory is based on natural speech data, a sentence repetition test was also conducted in order to compare the result with the order obtained from the multiple-choice tests and the order predicted by processability theory. The participants were 872 Japanese university students, whose TOEIC scores ranged from 200 to 875. The difficulty order of the 38 structures was displayed according to their Rasch difficulty estimates: The most difficult structure was subjunctive and the easiest one was present perfect with since in the sentence. The order was not in accord with the order predicted by processability theory, and the difficulty order derived from the sentence repetition test was not accounted for by processability theory either. In other words, the results suggest that processability theory only accounts for natural speech data, and not elicited data. Although the order derived from the repetition test differed from the order derived from the written tests, they correlated strongly when the repetition test used ungrammatical sentences. This study tentatively concluded that the students could have used their implicit knowledge when answering the written tests, but it is also possible that students used their explicit knowledge when correcting ungrammatical sentences in the repetition test. The difficulty order of grammatical structures derived from this study was not in accord with the order in which the structures appear in junior and senior high school textbooks in Japan. Their correlation was extremely low, which suggests that there is no empirical basis for textbook makers'/writers' policy regarding the ordering of grammar items. This study also demonstrated the difficulty of writing items testing the knowledge of the same grammar point that show similar Rasch difficulty estimates. Even though the vocabulary and the sentence positions were carefully controlled and the two items looked parallel to teachers, they often displayed very different difficulty estimates. A questionnaire was administered concerning such items, and the students' responses suggested that they seemed to look at the items differently than teachers and what they notice and how they interpret what they notice strongly influences item difficulty. Teachers or test-writers should be aware that it is difficult to write items that produce similar difficulty estimates and their own intuition or experience might not be the best guide for writing effective grammar test items. It is recommended to pilot test items to get statistical information about item functioning and qualitative data from students using a think-aloud protocol, interviews, or a questionnaire. / CITE/Language Arts

Many researchers have highlighted the need for students to have a willingness to communicate (WTC) in second and foreign language classrooms. WTC is important because it is believed that WTC leads to eventual communication both inside and outside the classroom. Previous research into WTC has centered mainly on the use of structural models and trait, self-reported measurements of WTC, but recent research has shown that WTC is also heavily dependent on the situation. However, very few studies recognize this and have, thus, not employed situational measurements of WTC. After a thorough review of WTC literature, 13 pertinent constructs were modified to reflect the situation in the foreign language classroom. These were related to constructs of the classroom, beliefs about communication; self-determined motivation; self-perceived competence; communication anxiety and willingness to communicate. A preliminary study employing exploratory factor analysis and Rasch analysis, followed by a main study conducted with and confirmatory factor analysis and Rasch analysis were undertaken with first- and second-year Japanese university students. The factor analysis was used to investigate the underlying structures of the factors and the Rasch analysis was used to determine fit, category functioning and dimensionality. Nine reliable and unidimensional factors were brought forward from the main study, which were Classroom Efficacy Factor and Classroom Affective Factor as the two classroom factors; Intrinsic Motivation for Communication, Introjected Regulation for Communication and External Regulation for Communication as the three self-determined motivation constructs, and finally, Self-Perceived Competence, Communicative Anxiety and Willingness to Communicate split in two subconstructs of pair/work and whole class activities. The second half the study was the formulation of a structural equation model using the above constructs to predict situational WTC. The model also included an often under-utilized resource, the teacher, who assessed the learners’ actual communication to identify if WTC leads to language use. All the fit indices in the final model (N = 376) were good, and the model included three additional paths. The model indicated that classroom constructs led to motivation and self-perceived competence, which predicted confidence. Motivation led directly to WTC and indirectly to WTC through confidence. Lastly, WTC predicted actual communication. The constructs in this study can be applied in other studies of situational WTC. This study helps to both expand our understanding of constructs affecting situational WTC and actual communication, and provides more validity to the construct of situational WTC. It also reaffirms the importance of what happens in the classroom, which is main arena for communication in the EFL setting. / Language Arts

Students who are the first in their families to attend college are less likely to earn a college degree as compared to their continuing-generation peers. In efforts to increase college graduation rates for first-generation college students, support programs designed to assist first-generation college students are increasing in numbers. These first- generation programs are relying on existing research to build effective curriculums. Even though an extensive body of literature exists in the fields of self-efficacy and first- generation college students, research investigating the self-efficacy of first-generation college students are extremely limited. The research is further limited when examining academic self-efficacy and generational status. The purpose of this study is to investigate if parental levels of education affect college students’ self-reported levels of academic self-efficacy. The following research questions guided this study: 1) Do survey response hierarchies differ between first-generation college students and their continuing- generation counterparts on a scale that measures academic self-efficacy?, 2) Do levels of item endorsability vary based upon parental levels of education? and 3) Do the results produced from the college student survey support the existing literature on first- generation college students and academic-self-efficacy? Quality control indicators were utilized to assess the soundness of the instrument and to ensure that the rating scale functioned appropriately. Variable maps were used to compare and contrast student responses and item hierarchies. Pairwise differential item functioning (DIF) was used to examine item endorsability based upon levels of parental education. Results encourage practitioners to be mindful of the importance of data-informed decision making.

Introduction Occupational therapists are concerned with enabling people to perform the daily life tasks they need, want, or are expected to perform for fullest possible integration into community living and participation in society. Children with mild disabilities have problems performing personal and instrumental activities of daily living (ADL) tasks at home or school, and that can limit their full integration and participation in their homes and school lives. There is a need, therefore, to identify their specific problems with ADL task performance so as to be able to develop effective interventions. Not only, there is a need for evidence related to effectiveness of occupational therapy interventions for children with mild disabilities, but also a need for valid occupational-therapy-specific evaluation tools for use with children. Purpose The purpose of this thesis was to contribute evidence to support the valid use of the Assessment of Motor and Process Skills (AMPS) with children, including children living in Middle Europe. More specifically, I aimed to evaluate validity evidence from different sources related to the use of the AMPS in occupation-based and occupation-focused evaluation and intervention. Method This thesis consisted of four studies, implemented in two phases. Phase one focused on evaluation of a) validity evidence of the AMPS scales in relation to internal structure and stability of item difficulty calibration values for a Middle European sample compared to samples from other world regions (Study I); b) the stability of the mean AMPS measures between typically-developing children from Middle Europe and from other world regions (Study II); and c) the sensitivity of the AMPS measures to discriminate between typically-developing children and children with and at risk for mild disabilities (Study III). Participants for phase one were from both Middle Europe and from other world regions and they were selected from the AMPS database, Ft. Collins, Colorado, USA. Data were analyzed using many-facet Rasch analyses, ANOVAs, regression analyses, related post-hoc tests, and effect size calculations. Phase two of the research project focused on evaluating validity evidence for the use of the AMPS as a standardized, occupation-based, and occupation-focused evaluation tool in the context of a feasibility study with children with mild disabilities implemented in a Swiss setting (Study IV). Data were analyzed based on feasibility objectives and the principles of deductive content analysis. The evaluation of validity evidence of the AMPS in relation to consequences of testing and test fairness was a focus of all studies (Studies I to IV). Results In Study I, data for 1346 participants from Middle Europe and 144,143 participants from other world regions were analyzed. The participants were between the ages of 3 and 103 years, and they were well or had a variety of diagnoses. The results revealed that overall the item difficulty calibration values of the AMPS remained stable and that only one out of 36 ADL items of the AMPS demonstrated DIF, but this DIF did not lead to DTF (i.e., all measures fell within 95% confidence bands). In Study II, data for 11,189 typically-developing children from Middle Europe and other world regions who were between the ages of 2 and 15 were analyzed. The results of ANOVAs revealed significant effects for mean ADL motor and for ADL process ability measures by region and a significant age by region interaction effect for mean ADL process ability. Out of 168 estimated contrasts between Middle Europe and the other world regions for mean ADL motor and ADL process ability, only seven were statistically significant (4.17%), and only two were more than ±1 SE from the international means. In Study III, regression analyses of data for 10,998 children, 4 to 15 years, who were typically-developing or with mild disabilities, revealed significant age by group interaction effects. Post hoc t tests revealed significant group differences in ADL ability at all ages beyond the age of 4. ADL process ability effect sizes were moderate to large at all ages and ADL motor ability effect sizes were mostly moderate to large age 6 and above. In Study IV, the use of the AMPS within the context of a feasibility study based on data of 17 Swiss children with mild disabilities was evaluated. The analyses revealed several strengths and problems that were related to the time, equipment, and materials for administering the AMPS, the adherence to standardized administration procedures, the scope of the AMPS as a test of ADL performance, and the reliable rating by the blinded rater. Conclusion This thesis provided evidence to support the validity of the AMPS measures and scales when used to evaluate quality of ADL task performance of persons from Middle Europe. Additionally, this thesis provided evidence that the international age-normative means of the AMPS are likely applicable to children from Middle Europe. Moreover, the findings supported the sensitivity of the AMPS measures to discriminate between typically-developing children and children with and at risk for mild disabilities. When it comes to implementation of the AMPS in the context of a feasibility study, the findings indicated both strengths and problems in using the AMPS as an outcome measure that need to be considered when planning further studies.

Functional vision refers to the use of vision to perform day-day tasks and is assessed by the ability to perform these tasks. Assessment of functional vision is an integral component of the management of children with visual impairment. The results of the assessment help in designing appropriate educational and rehabilitation intervention strategies. The L V Prasad-Functional Vision Questionnaire (LVP-FVQ) is a reliable and valid tool for assessing self-reported functional vision performance (FVP) in children. Self-reports are obviously the child's perception of his or her ability to perform certain tasks but they may not reflect actual performance. Various studies of FVP in adults have used actual performance measures of everyday tasks, but very few studies, even in adults with visual impairment, have compared self-reports and performance measures and none have included identical tasks on the 2 methods of assessment. To date, no study has assessed FVP using performance measures of daily tasks in the paediatric population. Therefore, the aims of the current study were: (1) To develop performance measures of FVP and compare them with self-reports of FVP from the LVP-FVQ in a prospective cohort of Indian school-going children with visual impairment. (2) To investigate the effect of a psychological attribute, self-concept, on self-reports, performance measures and the relationships between the 2 measures. (3) To investigate the relationship between clinical measures of vision and FVP. Performance measures of FVP for children with visual impairment were developed for 17 day to day tasks for comparison with self-reports of the same tasks for the LVP-FVQ. The LVP-FVQ was verbally administered by the researcher to 178 Indian school-going children aged between 8 and 17 years with visual impairment. Similarly, the performance of each of the tasks by these children was measured by the researcher. The performance measures for most of these tasks were recorded on continuous scales and later categorized to match the ordinal ratings from the LVP-FVQ. The self-report and performance measure ratings for the 17 tasks were then converted into the same metric using a Rasch model allowing an accurate picture of whether and how these two measures of FVP compared with each other. Rasch analysis was used to estimate the person ability and item difficulty for FVP from the 2 methods of assessment. Self-reports showed stronger correlations with performance measures of FVP than were hypothesized. Similar to some studies in adults, binocular high-contrast visual acuity was found to be the single most significant predictor of a child's functional vision performance. Contrary to expectations, self-concept did not have a significant effect on the relationship between the 2 measures. A few reasons for the stronger than expected relationship between the 2 methods of assessment of FVP in children with visual impairment are suggested. Firstly, the use of identical tasks for self-reports and performance measures of FVP is likely to improve the relationship. Secondly, the LVP-FVQ was developed using focus groups of children with visual impairment, their parents, low vision specialists and rehabilitation professionals leading to good content validity. Since children were included in the development of the LVP-FVQ, the tasks were representative of a child's typical daily life. Thus, the performance measures were also suited to the day-day tasks of school-going children but were not tapping any social and psychological issues relating to visual impairment. Thirdly, the use of Rasch analysis which addresses many of the issues of unequal measurement and defines a hierarchy of items for self-reports and performance measures could have led to higher correlations in the present study. Finally, the high reliability and validity of self-reports and performance measures of FVP in the present study may have contributed to the higher than expected correlations. None of the demographic variables or self-concept affected the relationship between self-reports and performance measures of FVP, but self-concept had a weak significant association with self-reports. This result is unique to this study and warrants further investigation. Binocular high-contrast visual acuity alone, the most common visual function measured in ophthalmic clinics, explained between one-third and two-thirds of the variance in functional vision performance. This confirms the expected trend that with worse visual impairment, FVP is lower. The addition of the variable, self-concept, resulted in a very small increase in the variability explained for self-reported FVP. Similarly, the addition of other clinical measures of vision such as binocular low contrast visual acuity and colour vision resulted in a small increase in the variability explained for performance measures of FVP. The correlation between binocular high-contrast visual acuity and performance measures of FVP was statistically significantly higher than that between binocular high-contrast visual acuity and self-reports of FVP. There are a few possible reasons for this higher correlation. Firstly, performance measures are considered to be a more "objective" form of assessment, while self-reports are a child's perception of his or her ability and therefore lack a context, which may result in either over-estimation or under-estimation of actual ability. Furthermore, performance measures include dimensions such as the time taken to perform a task or other criteria specific to a task, while self-reports do not use such qualifiers. Secondly, the higher correlation may be the result of the visual complexity of some of the tasks. While self-concepts of children with visual impairment played a small but significant role in the self-reported FVP, studies in adults with visual impairment have suggested that other psychological factors such as mood, anxiety, motivation etc. are associated with an individual's perception of visual performance. Future studies are required to explore the possible role of these and other factors in FVP in Indian school-going children with visual impairment. This thesis makes a significant contribution to the field of paediatric low vision rehabilitation by providing performance measures of FVP and relating them to self-reports in children with visual impairment and their relationship with common measures of visual function. With self-reports, the child is reporting his or her perception of ability to complete a task, where performance measures examine the child's ability to complete a task by observing his or her performance. Thus, although the two methods are comparable, it is because of the different yields from each of these measures that they are not considered interchangeable. A combination of the 2 measures where practical would perhaps provide a richer depiction of the FVP of children with visual impairment. As developing countries such as India have limited resources allocated for eye care services where less than seven percent of the gross national product is spent on health care, self-reports can be utilized together with clinical measures of vision (mainly visual acuity) to assess the FVP in children with visual impairment in a community setting. However, both methods of assessment of FVP together with clinical measures of vision are essential if a comprehensive assessment of FVP is to be carried out in children with visual impairment. Information from these assessments can help clinicians better understand the functioning of children with visual impairment and incorporate them in the management of low vision in school-going children with visual impairment in India.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less. Marie Curie Debates about how best to test people from different contexts and backgrounds continue to hold the spotlight of testing and assessment. In an effort to contribute to the debates, the purpose of the study was to develop and evaluate the viability and utility of nonverbal figural reasoning ability items that were developed based on inspirations from African cultural artefacts such as African material prints, art, decorations, beadwork, paintings, et cetera. The research was conducted in two phases, with phase 1 focused on the development of the new items, while phase 2 was used to evaluate the new items. The aims of the study were to develop items inspired by African art and cultural artefacts in order to measure general nonverbal figural reasoning ability; to evaluate the viability of the items in terms of their appropriateness in representing the African art and cultural artefacts, specifically to determine the face and content validity of the items from a cultural perspective; and to evaluate the utility of the items in terms of their psychometric properties. These elements were investigated using the exploratory sequential mixed method research design with quantitative embedded in phase 2. For sampling purposes, the sequential mixed method sampling design and non-probability sampling strategies were used, specifically the purposive and convenience sampling methods. The data collection methods that were used included interviews with a cultural expert and colour-blind person, open-ended questionnaires completed by school learners and test administration to a group of 946 participants undergoing a sponsored basic career-related training and guidance programme. Content analysis was used for the qualitative data while statistical analysis mainly based on the Rasch model was utilised for quantitative data. The results of phase 1 were positive and provided support for further development of the new items, and based on this feedback, 200 new items were developed. This final pool of items was then used for phase 2 – the evaluation of the new items. The v statistical analysis of the new items indicated acceptable psychometric properties of the general reasoning (“g” or fluid ability) construct. The item difficulty values (pvalues) for the new items were determined using classical test theory (CTT) analysis and ranged from 0.06 (most difficult item) to 0.91 (easiest item). Rasch analysis showed that the new items were unidimensional and that they were adequately targeted to the level of ability of the participants, although there were elements that would need to be improved. The reliability of the new items was determined using the Cronbach alpha reliability coefficient (α) and the person separation index (PSI), and both methods indicated similar indices of internal consistency (α = 0.97; PSI = 0.96). Gender-related differential item functioning (DIF) was investigated, and the majority of the new items did not indicate any significant differences between the gender groups. Construct validity was determined from the relationship between the new items and the Learning Potential Computerised Adaptive Test (LPCAT), which uses traditional item formats to measure fluid ability. The correlation results for the total score of the new items and the pre- and post-tests were 0.616 and 0.712 respectively. The new items were thus confirmed to be measuring fluid ability using nonverbal figural reasoning ability items. Overall, the results were satisfactory in indicating the viability and utility of the new items. The main limitation of the research was that because the sample was not representative of the South African population, there were limited for generalisation. This led to a further limitation, namely that it was not possible to conduct important analysis on DIF for various other subgroups. Further research has been recommended to build on this initiative. / Industrial and Organisational Psychology

Context: Medical management for head and neck cancer (HNC) often includes neck dissection surgery, a side effect of which is shoulder dysfunction. There is no consensus for which patient-reported outcome measure (PRO) is most appropriate to quantify shoulder dysfunction in this population. Objective: The aims of this research study were to: (1) use Rasch methodologies to assess construct validity and overall appropriateness of test score interpretation of Disability of the Arm, Shoulder and Hand (DASH), QuickDASH, Shoulder Pain and Disability Index (SPADI) and Neck Dissection Impairment Index (NDII) in the HNC population; (2) determine appropriateness of use of University of Washington Quality of Life (UW-QoL) shoulder subscale as a screening tool for shoulder impairment; (3) recommend a new PRO, or combination of PROs, that more accurately portrays the construct of shoulder dysfunction in the HNC population. Design: One hundred and eight-two individuals who had received a neck dissection procedure within the past 2 weeks to 18 months completed the PROs. Rasch methodologies were utilized to address the primary aim of the study through consideration of scale dimensionality [principal components analysis, item and person fit, differential item functioning (DIF)], scale hierarchy (gaps/redundancies, floor/ceiling effects, coverage of ability levels), response scale structure, and reliability (person and item reliability and separation statistics). The secondary aim was addressed through correlational analysis of the UW-QoL (shoulder subscale), DASH, QuickDASH, SPADI and NDII. Results: The DASH did not meet criteria for unidimensionality, and was deemed inappropriate for utilization in this sample. The QuickDASH, SPADI and NDII were all determined to be unidimensional. All scales had varying issues with person and item misfit, DIF, coverage of ability levels, gaps/redundancies, and optimal rating scale requirements. The NDII meets most requirements. All measures were found to meet thresholds for person and item separation and reliability statistics. The third aim of this study was not addressed because the NDII was determined to be appropriate for this population. Conclusions: Rasch analysis indicates the NDII is the most appropriate measure studied for this population. The QuickDASH and SPADI are recommended with reservation. The DASH and the UW-QoL (shoulder subscale) are not recommended.
