BACKGROUND: Almost 25%of workers in the European Union suffer from back pain, and 23%complain of muscle pain. Sixty-two percent of workers carry out repetitive operations with their hands or arms, 46%work in painful or tired positions and 35%carry or handle loads. OBJECTIVE: This study aimed to translate, culturally adapt and validate the Italian version of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ-I). METHODS: Translation and cultural adaptation procedures followed international guidelines. Participants were recruited from among the personnel components of the Italian Air Force, who were between 18 and 65 years old. Cronbach’s alpha and the intraclass correlation coefficient (ICC) were calculated to assess internal consistency and stability, respectively. The CDMQ-I was administered together with the Visual Analogic Scale (VAS), and the validity was evaluated using Pearson’s correlation coefficient. RESULTS: All CDMQ-I items were either identical or similar in meaning to the original version’s items. The scale was administered twice with a retest after seven to 10 days to 66 participants. Cronbach’s alpha was higher than 0.761, and the ICC ranged between 0.737 and 0.952. Pearson’s correlation coefficient showed positive and significant correlations (p >  0.01). CONCLUSIONS: The study produced an Italian version of the CMDQ with good reliability and validity. This scale is a useful tool to investigate the frequency and intensity of musculoskeletal disorders in various categories of workers.

Today, many organizations have realized an important of pre-development process in order to compete with competitor through drastically introduce new product in the market. In view of that, understanding critical factors that contribute to successful pre-development process implementation is becoming the more important. However, most of past studies were conducted in large organization, very little has been done in small and medium enterprise (SMEs). SMEs have certain limitation in terms of their financial, human, technical, and resources that could hinder their progress towards implementing pre-development process. This paper reviews and analyses CSFs developed by previous authors in order to propose a set of CSFs which were thought to be critical for SMEs. After that the questionnaire developed in this study will be analysis using factors analysis and reliability test in order to examine construct validity and reliability. An initial draft of the questionnaire was developed based on the literature. The questionnaire was pre-tested by academicians and industry practitioners. After that the questionnaire was piloted at 55 food and beverage manufacturing SMEs to check its reliability by using Cronbach’s alpha value. In addition, principle component analysis was carried out to test the construct validity. All the factors in the survey instrument had a Cronbach’s alpha coefficient of more than 0.7 which may be considered satisfactory. Through factor analysis, all KMO values were found above acceptable value of 0.50. All Bartlett’s Test in this analysis was found to be significant. Therefore the instrument is valid and reliable and considered as satisfactory. Nine CSFs, which are believed suitable for SMEs have been proposed in this paper. Through systematic identification and validation, it is hope that the set of CSFs could be used as guides for SMEs to implement pre-development process successfully.

ABSTRACT Objective: To evaluate the psychometric properties in terms of validity and reliability of the scale Self-efficacy and their child's level of asthma control: Brazilian version. Method: Methodological study in which 216 parents/guardians of children with asthma participated. A construct validation (factor analysis and test of hypothesis by comparison of contrasted groups) and an analysis of reliability in terms of homogeneity (Cronbach's alpha) and stability (test-retest) were carried out. Results: Exploratory factor analysis proved suitable for the Brazilian version of the scale (Kaiser-Meyer-Olkim index of 0.879 and Bartlett's sphericity with p < 0.001). The correlation matrix in factor analysis suggested the removal of item 7 from the scale. Cronbach's alpha of the final scale, with 16 items, was 0.92. Conclusion: The Brazilian version of Self-efficacy and their child's level of asthma control presented psychometric properties that confirmed its validity and reliability.

The Impact

Introduction It is required to have validated instruments in health science students that identify unhealthy habits and assess the impact of educational interventions and programs aimed at promoting a healthy lifestyle. Objective To evaluate the validity and reliability of an instrument to measure medical students' lifestyles. Methods A lifestyle questionnaire was developed using the Delphi technique by a group of experts. The final questionnaire was applied to 332 students of the School of Medicine of the Ricardo Palma University in 2017. A preliminary examination was carried out to assess preconditions for construct validity—including the correlation matrix, the Kaiser Meyer Olkin statistic, and the Bartlett sphericity test. Factor analysis was used for construct validity, and the possible resulting factors were extracted through the principal component analysis. Cronbach's alpha coefficient was calculated to assess the instrument reliability. Results In this study, 41.6% of participants were men with a mean age of 20 years (standard deviation = 3). The preconditions for the factor analysis were a Kaiser Meyer Olkin coefficient = 0.773 and a significant Bartlett sphericity test. For the 47 items of the final questionnaire, the factor analysis showed an explained variance of 56.7% with eigenvalues greater than one. Cronbach's alpha was 0.78. The final questionnaire could assume values between -23 to 151 points. Based on a cut point of 71 points, the prevalence of students with an unhealthy lifestyle was 73.6%. Conclusion The developed instrument has acceptable validity and reliability to measure lifestyle in medical students. For external validation, studies in other university populations are suggested.

This study aims to investigate the construct validity and reliability of the checklist for qualitative analysis of the overhand serve in Volleyball. Fifty-five male subjects aged 13-17 years participated in the study. The overhand serve was analyzed using the checklist proposed by Meira Junior (2003), which analyzes the pattern of serve movement in four phases: (I) initial position, (II) ball lifting, (III) ball attacking, and (IV) finalization. Construct validity was analyzed using confirmatory factorial analysis and reliability through the Cronbach’s alpha coefficient. The construct validity was supported by confirmatory factor analysis with the RMSEA results (0.037 [confidence interval 90% = 0.020-0.040]), CFI (0.970) and TLI (0.950) indicating good fit of the model. In relation to reliability, Cronbach’s alpha coefficient was 0.661, being this value considered acceptable. Among the items on the checklist, ball lifting and attacking showed higher factor loadings, 0.69 and 0.99, respectively. In summary, the checklist for the qualitative analysis of the overhand serve of Meira Junior (2003) can be considered a valid and reliable instrument for use in research in the field of Sports Sciences.
