Agreement Between Test And Retest

A recent systematic review examined the psychometric properties of eleven labour productivity questionnaires [11]. For only four questionnaires, data are available on the reliability of absenteeism. However, for several reasons, we cannot compare our results with these questionnaires: no CCI or Kappa was performed [34,35,36], unknown type of CCI [37, 38] or any other recall period (3 months) and Kappa calculation (Absenteeism 0 vs. > 0 days) [39]. The reliability test study of 175 university students within three to nine months found correlations between 0.30 and 0.77 for the six evaluation categories (Bernard 1949). The reliability of the Inter-Scorer is high. Clarke et al. (1947) reported an approximate 85% agreement between two independent scorers in the P-F test. Lindzey (1954) conducted a validity study with thematic apperception (TAT) as a measure of the criterion and compared the results of the two tests.

He also compared the results of the P-F test between groups that were very high and very low in prejudices against minorities. It found that the results of the TAT and P-F tests were not correlated with extra-penalty and intropunity and that no difference was found between the high and weak groups. Other studies have independently evaluated the Kibler LSST. Gibson et al (1995) reported reliability of 0.81 to 0.94 and reliability of 0.18 to 0.92. T`Jonck et al (1996) reported similar ICCs for the reliability of intratesters (0.69 to 0.96) and CCIs for flight safety between 0.72 and 0.90. In addition to the reported reliability coefficients, Gibson et al (1995) and T`Jonck et al (1996) identified lower intra-test correlation and intertest coefficients with the Kibler 3 position. All researchers recognize the increased difficulty of touching the lower angle of the shoulder blade in position 3 due to the greater contraction of the muscles surrounding the shoulder blade (Kibler, 1998a; Gibson et al., 1995; T`Jonck et al., 1996). The adequacy of continuous variables was analyzed by the standard measurement error, sd being the SD of all participants obtained from an ANOVA analysis with the “SStotal” formula, and ICC is the repeat reliability coefficient [21]. The SEM has been transformed into the smallest verifiable changes at the individual level C_.

This number reflects the smallest individual change in a score that can be considered a real change about each measurement error within a person. The individual DEDC was transformed into A SDC for a group (SDC group) by dding the individual DEDC by √n. We proposed a positive rating for the agreement if the absolute measurement error (single DDC for change within individuals and DEDC group for group change) is below the minimum (MIC, see responsiveness) [27, 28]. WHO-5 is a one-dimensional generic questionnaire that reflects the mental well-being of construction over the past two weeks [5]. The scale was developed in 1998 and is widespread [6]. WHO-5 contains five positive formulations that are evaluated on a 6-point ordinal scale ranging from 5 “all the time” to “0 at no time.” Gross values between 0 and 25 are multiplied by 4 to obtain a percentage of points between 0 (worst) and 100 (best).
