Item Analysis of English Final Semester Test

Numerous studies have been conducted on the item test analysis in English test. However, investigation on the characteristics of a good test of English final semester test is still rare in several districts in East Java. This research sought to examine the quality of the English final semester test in the academic year of 2018/2019 in Ponorogo. A total of 151 samples in the form of students’ answers to the test were analysed based on item difficulty, item discrimination, and distractors’ effectiveness using Quest program. This descriptive quantitative research revealed that the test does not have good proportion among easy, medium, and difficult item. In the item discrimination, the test had 39 excellent items (97.5%) which meant that the test could discriminate among high and low achievers. Besides, the distractors could distract students since there were 32 items (80%) that had effective distractors. The findings of this research provided insights that item analysis became important process in constructing test. It related to find the quality of the test that directly affects the accuracy of students’ score.

ANALYSIS OF MEASURES ITEMS IN DEVELOPMENT OF INSTRUMENTS SELF-ASSESSMENT (RASCH MODELING APPLICATION)

This analysis aims to determine the quality of the instrument items that have been developed in the empirical test phase one. Tests were carried out on 46 items to 219 respondents in SMA Ksatrya Jakarta. The item quality is seen from the fit or not fit and the level of difficulty of the item that has been developed. The fit or unfit criteria are seen in INFIT and OUTFIT, both MNSQ and ZSTD, and Pt-Measure Correlation values. The level of difficulty of the item is seen in the entry number column which is indicated by the magnitude of the logit value and has been sorted from the hardest to the easiest. Based on the results of analysis with the help of software winstep obtained 39 items statement fit with the model and the number of respondents 194, the three criteria above (MNSQ, ZSTD, and Pt.Measure Correlation) has been met. This means that 39 items are valid. The result of the analysis also shows the most difficult item sequence is item 5 with logit value 63,32, and the easiest item is item 44 with logit value 36,13. The resulting fit instrument must have gone through several stages of analysis. When there are items that are not fit, the item is issued, as well as the respondent. So that obtained a set of measuring instruments that are valid / fit with the model and can be used for the purposes of assessment. Keyword: self-assessment, infit, outfit, ZSTD, and Rasch Model.

A hierarchy of distress: Mokken scaling of the GHQ-30

BackgroundHierarchical cumulative scales are common and informative in psychology. The General Health Questionnaire (GHQ) does not appear to have been subjected to an analysis that examines the hierarchical and cumulative nature of its items. We report an analysis of data from the 30-item GHQ (GHQ-30) as part of the Health and Lifestyle Survey (HALS).MethodData from 6317 participants who completed the GHQ-30 as part of the HALS were analysed using the Mokken Scaling Procedure (MSP), which is a computer program that searches polychotomous data for hierarchical and cumulative scales on the basis of a range of diagnostic criteria.ResultsA final scale consisting of nine items from the GHQ-30 was obtained that, according to the criteria for a Mokken scale, was a reliable and very strong scale. The least difficult item in the scale is ‘been (un)able to face up to your problems?’ and the most difficult item is ‘felt that life isn't worth living?'ConclusionsItems from the GHQ-30 form a short hierarchical and cumulative scale. The majority of these items also appear in the GHQ-12. The nine-item GHQ shows better distribution properties than the GHQ-30 and compares very favourably with the GHQ-12.

Manual Ability Measure (MAM-16): A Preliminary Report on a New Patient-Centred and Task-Oriented Outcome Measure of Hand Function

The purpose of this study was to develop an easy-to-use and psychometrically sound outcome instrument that is task-oriented and patient-centred. One hundred fifteen patients with a variety of hand impairments completed a rating scale of perceived manual ability (i.e., the Manual Ability Measure). The first 70 patients also completed two other questionnaires about physical health and psychological well-being. Rasch Analyses were conducted to transform the ordinal ratings into linear measures; Rasch statistics were used to evaluate its measurement properties at both scale and item levels. Eighty-three original items were reduced to 16 common tasks; Rasch reliabilities were good; the easy-to-difficult item hierarchy makes sense clinically. Moderate correlations were found between manual ability, physical function and general sense of well-being. The results of this preliminary study suggest that the MAM is a promising outcome measure that has adequate psychometric properties and can be used to complement other objective clinical measurements.
