Item Chinese Manual of the Model of Human Occupation Screening Tool (MOHOST)(School of Occupational Therapy, College of Medicine, National Taiwan University, 2009) Fan, Chia-WeiItem A Psychometric Study of the Model of Human Occupation Screening Tool (MOHOST)(2010) Fan, Chia-WeiObjective: This study examined the psychometric properties of the Model of Human Occupation Screening Tool (MOHOST) using item response theory and classical test theory approaches for clients with psychiatric disorders. Methods: Data, including demographic variables and scores on the MOHOST and a version of the Health of the Nation Outcomes Scale, were retrieved from case records of 1039 adult psychiatric service users. Results: Participants ranged in age from 18 to 102 and 57% were female and 43% were male. Most (94%) were unemployed, retired, or receiving other education or training. The items that make up each of the MOHOST subscales demonstrated good discriminant validity and excellent goodness of fit showing that the items measured the MOHO constructs unidimensionally. All subscales were able to distinguish clients into at least three statistically distinct strata and showed convergence with an independent measure of functioning. Conclusion: Findings from this study must take into account implicit limitations associated with the use of Rasch analysis and classical test theory. At the same time, results did support use of the MOHOST for research and clinical purposes. The MOHOST demonstrated good construct validity, item separation reliability, and concurrent validity. As a measure of occupational participation, the MOHOST offers practitioners and researchers a valid and reliable measure of volition, habituation, communication/interaction skills, process skills, motor skills, and environmental influences on participation.Item Motivational Change Over the Course of Hippotherapy: An Exploratory Study of Three Children with Autism(2010) Fan, Chia-WeiThis article describes the findings from a research study looking at the motivational pathways of children with autism while participating in a 16‐week hippotherapy intervention. The Pediatric Volitional Questionnaire (PVQ) was used to document quantitative data for the changes in motivation that each child experienced, and videotaping was used for qualitative information. The study found that the motivation of children with autism will take highly individual pathways over time, and will be dependent on environmental factors.Item Examining the Validity of the Model of Human Occupation Screening Tool: Using Classical Test Theory and Item Response Theory(2011) Fan, Chia-WeiIntroduction: This study examined the psychometric properties of the Model of Human Occupation Screening Tool, using both item response theory and classical test theory. Method: One hundred and one people with mental health problems, aged 18–65 years, were recruited. The Chinese version of the Model of Human Occupation Screening Tool, the National Taiwan University Hospital Symptom Checklist, the Volitional Questionnaire, the Assessment of Communication and Interaction Skills, and the Mini Mental State Examination were administered. Rasch analysis and correlational analysis were used to examine the construct, convergent, divergent validity and known group validity. Results: Rasch analysis confirmed that there were six subscales within the Chinese version of Model of Human Occupation Screening Tool. The Volitional Questionnaire strongly correlated with the volition subscale (r = 0.583). The Assessment of Communication and Interaction Skills strongly correlated with the communication and interaction subscale (r = 0.815). The Mini Mental State Examination was moderately correlated with the process subscale (ρ = 0.334) and the symptomatology was not associated with any of the subscales as expected. There were significant differences on selected subscale scores across four known groups of participants. Conclusion: The Chinese version of the Model of Human Occupation Screening Tool was valid when applied to people with mental health problems.Item Examining Occupational Changes in Patients in Low and Medium Secure Settings in England(2012-03) Fan, Chia-WeiItem The Science Behind Preparing Students for the National Examination(2012-04) Radloff, Jennifer C.Item Survey of Assessment Tools Taught in Entry-level Master's OT Programs across the United States(2012-04) Radloff, Jennifer C.Item Clinical Assessment of Modes - Therapist Outcomes Version (CAM-T): Communicating with Your Client(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Clinical Assessment of Modes—Observational Version (CAM-O): Communicating with Your Therapist—Observational Version(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Clinical Assessment of Modes - Client Preferences Version (CAM-C1): Communicating with Your Therapist(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Clinical Assessment of Modes - Client Outcomes Version (CAM-C2): Communicating with your Therapist (Mandarin Version)(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem The Test–Retest Reliability and the Minimal Detectable Change of the Purdue Pegboard Test in Schizophrenia(2013) Fan, Chia-WeiBackground/Purpose: The Purdue pegboard test is widely used in measuring the hand dexterity of patients with schizophrenia. In patients with schizophrenia, the test–retest reliability and minimal detectable change (MDC) of this test remain largely unknown, limiting the interpretability of this popular measure. The purpose of this study was to estimate the test–retest reliability and the MDC of the Purdue pegboard test for patients with schizophrenia. Methods: A total of 147 patients with schizophrenia participated in this study. The participants were administrated the five subtests of the Purdue pegboard test, three trials in a row at both of the two sessions 1 week apart. The intraclass correlation coefficient (ICC) was used to examine the test–retest reliability and the MDC was calculated on the basis of standard error of measurement. Results: The test–retest reliabilities of the five subtests were moderate to good (ICC = 0.73–0.88). The MDC (MDC%) was 3.0 (22.9%) for the dominant hand subtest, 3.1 (26.1%) for the nondominant hand subtest, 3.0 (31.7%) for the both hands subtest, 6.1 (17.7%) for the dominant + nondominant + both hands subtest, and 8.5 (35.3%) for the assembly subtest. Conclusion: Our results reveal that the Purdue pegboard test has moderate-to-good test–retest reliability but substantial random measurement error. These findings should enable clinicians and researchers to monitor and interpret the changes in the hand dexterity of patients with schizophrenia more accurately and confidently.Item Clinical Assessment of Modes - Client Outcomes Version (CAM-C2): Communicating with Your Therapist(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Evaluating the Psychometric Properties of a Clinical Vocational Rehabilitation Outcome Measurement: The Assessment of Work Performance(2013) Fan, Chia-WeiThis study examined the validity and reliability of the Assessment of Work Performance (AWP) using Rasch analysis. The AWP was administered to 365 clients with a variety of work-related problems. Rasch analysis and principal component analysis were used to examine the appropriateness of the rating scales and unidimensionality of AWP items. The person-response validity, internal consistency, targeting appropriateness, and differential item function were also analyzed. The Rasch analysis confirmed the 4-point rating scale, and the item set met the criteria of unidimensionality. The AWP exhibited satisfactory person-response validity and internal consistency. Among the three subdomains, the targeting of item-difficulty was sufficient in the motor skills and process skills subdomains. Differential item functioning was found across gender and diagnoses. This study presented evidence to support that the AWP functioned as a reliable and valid assessment in assessing work performance.Item Clinical Assessment of Modes - Client Outcomes Version (CAM-C2): Communicating with Your Therapist (Spanish Version)(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Clinical Assessment of Modes - Client Preferences Version (CAM-C1): Communicating with Your Therapist (Spanish Version)(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-WeiItem Clinical Assessment of Modes - Client Preferences Version (CAM-C1): Communicating with Your Therapist (Mandarin Version)(University of Illinois at Chicago, Department of Occupational Therapy, 2013) Fan, Chia-Wei
