The cross-sectional study was conducted amongst thirty eight government supporting staff who mainly doing sedentary task in Malaysia Maritime Enforcement Affair Division (MMEAD) (49%) and Ministry of Health (MOH) (51%) in Putrajaya. The investigation aims to determine the association between working postures and musculoskeletal disorders (MSD) among office workers where all respondents were selected in 5 sections; administrative (64%), financial (12%), counter/assistant (12%), human resources management (6%) and procurement section (6%). Self-reported questionnaires using Nordic questionnaire were used in this investigation. Besides, posture analysis was done based on Rapid Upper Limb Assessment (RULA) and office ergonomics checklist adapted from Texas Department of Insurance, Division of Workers Compensation (2008) were used as the instrumentations of this investigation. Face validity and reliability testing for the questionnaire and intra tester reliability for the posture assessment was done to ensure true quality of the results and analysis. From the analysis, the highest prevalence of MSD complained is lower back pain (LBP) 57.9% while the lowest prevalence is elbow pain (EP) 2.6%. Result shows 31.6% of the respondents believe the pain is caused by working activities. Based on the ergonomics checklist, MMEAD shows the highest mean (64.84%) of non compliance, where all the workstations scored more than 50% compared with MOH. Based on RULA observation, most of the workstation scores in action level 3 (grand score 5-6). In conclusion, the high complained of MSD is due to awkward postures, unsuitable workstation and lack of knowledge related to the areas to apply in everyday routine and it shows that working postures have a direct contribution on MSD complained by the office workers in Putrajaya.

BACKGROUND: Musculoskeletal disorders (MSDs) represent one of the leading causes of occupational injury and disability. Awkward body posture while typing is associated with MSDs among the computer users. RULA (rapid upper limb assessment) is a subjective observation method of posture analysis for use in ergonomics investigations of workplaces where work-related upper limb disorders are reported. To date, no data available on reliability and validity of RULA among the bank employee’s using computers. OBJECTIVE: To examine the validity and reliability of RULA among the bank employees’ using computers.  MATERIALS AND METHODS: A sample of bank employee were recruited by simple random sampling technique to take part in this validity and reliability study. All anthropometric measurement was taken before the beginning of the study including age, height and weight. The concurrent validity of RULA was established with the criterion referenced, Rapid Entire Body Assessment (REBA). Principal investigator recorded both the scores of RULA and REBA to estimate the concurrent validity. Intra-rater reliability of RULA was established by the principal investigator across two trials on the same group of participants in the same environmental condition and same timings with a gap of 2 days. Inter–rater reliability of RULA was established by the principal investigator and another researcher on the same group of participants with in the same environmental conditions and same with a gap of 2 minutes. RESULT: Total 301 Participants were recruited in this study, in which 170 participants were males, and other 131 were females. Concurrent validity of RULA with the criterion measure REBA is found to be good as measured by spearman’s rank correlation test, ρ=0.91 (p<0.001). Intra-and inter-rater reliability of RULA is found to excellent with ICC=0.92 (0.90-0.94) and 0.91 (0.89-0.93) respectively. CONCLUSION: Validity and reliability of RULA have been established among the bank employees’ using computers. There exists good validity and excellent reliability among them.

Purpose The goal of this clinical focus article is to illustrate how speech-language pathologists can document the functional language of school-age children using language sample analysis (LSA). Advances in computer hardware and software are detailed making LSA more accessible for clinical use. Method This clinical focus article illustrates how documenting school-age student's communicative functioning is central to comprehensive assessment and how using LSA can meet multiple needs within this assessment. LSA can document students' meaningful participation in their daily life through assessment of their language used during everyday tasks. The many advances in computerized LSA are detailed with a primary focus on the Systematic Analysis of Language Transcripts (Miller & Iglesias, 2019). The LSA process is reviewed detailing the steps necessary for computers to calculate word, morpheme, utterance, and discourse features of functional language. Conclusion These advances in computer technology and software development have made LSA clinically feasible through standardized elicitation and transcription methods that improve accuracy and repeatability. In addition to improved accuracy, validity, and reliability of LSA, databases of typical speakers to document status and automated report writing more than justify the time required. Software now provides many innovations that make LSA simpler and more accessible for clinical use. Supplemental Material https://doi.org/10.23641/asha.12456719

Traditionally, speech-language pathologists (SLP) have been trained to develop interventions based on a select number of perceptual characteristics of speech without or through minimal use of objective instrumental and physiologic assessment measures of the underlying articulatory subsystems. While indirect physiological assumptions can be made from perceptual assessment measures, the validity and reliability of those assumptions are tenuous at best. Considering that neurological damage will result in various degrees of aberrant speech physiology, the need for physiologic assessments appears highly warranted. In this context, do existing physiological measures found in the research literature have sufficient diagnostic resolution to provide distinct and differential data within and between etiological classifications of speech disorders and versus healthy controls? The goals of this paper are (a) to describe various physiological and movement-related techniques available to objectively study various dysarthrias and speech production disorders and (b) to develop an appreciation for the need for increased systematic research to better define physiologic features of dysarthria and speech production disorders and their relation to know perceptual characteristics.

Abstract. This study examines the psychometric properties of the IQCODE and its applicability in the Iranian elderly population. A group of 95 elderly patients with at least 4 years of formal education who fulfilled the criteria of DSM-IV-TR for dementia were examined by the MMSE and the AMTs. The Farsi version of the IQCODE was subsequently administered to their primary caregivers. Results showed a significant correlation ( p = .01) between the score of the questionnaire and the results of the MMSE ( r = −0.647) and AMTs ( r = −0.641). A high internal reliability of the questionnaire was confirmed by Cronbach’s alpha coefficient (α = 0.927) and test-retest reliability by correlation coefficient ( r = 0.81). This study found that the IQCODE has acceptable psychometric properties and can be used for evaluating the cognitive state in the elderly population of Iran.

This study introduces the psychometric qualities of the Job Stressor Appraisal Scale (JSAS), a part of the Job Stress Battery, which comprehensively measures job stress in terms of job stressors, moderators, and strains. The JSAS measures employees’ appraisals of job stressors by considering both their frequency and intensity. To test its psychometric qualities, we administered the JSAS to a sample of 1,069 employees in Turkey. Factor analysis revealed a 5-factor structure, with 43 items explaining 46.1% of the variance. Cronbach’s α coefficients of the factors and the total scale varied between .66 and .93. In terms of construct and convergent validities, results generally showed significant correlations in the expected directions. These findings obtained on the validity and reliability of the scale imply good psychometric qualities.
