Personality tests to pursue (or avoid): Find the right personality, behavioral tests for your company “For the MBTI, the evidence says not very, no, no and not really.” “In social science, we use four standards: are the categories reliable, valid, independent, and comprehensive?” Adam Grant, a professor of industrial psychology at the University of Pennsylvania’s Wharton School, wrote in an essay on the subject.
Many researchers, however, have long questioned the MBTI’s scientific merit. The company’s website boasts the assessment has a 90% accuracy rating and a 90% average test-retest correlation, “making it one of the most reliable and accurate personality assessments available.” The test sorts people into one of 16 four-letter personality types based on their preferences for Sensing (S) or Intuition (N), Extraversion (E) or Introversion (I), Thinking (T) or Feeling (F), and Judging (J) or Perceiving (P). It’s also one of the most regularly debunked. The Myers-Briggs Type Indicator is one of the most popular personality tests in the world.
But sample type had no effect on the reliability estimation for OHS-S (short-form), and field of study had no effect for both short and long form reliability estimates.Watch Video: The Myers-Briggs type indicator is still popular, but is it accurate? In addition, it was concluded that number of items had a statistically significant effect on the reliability estimation in terms of heterogeneity of true effect sizes, and sample type had a statistically significant effect on the reliability estimation for OHS (long-form). As a result of the research, it was found that the mean alpha was. The effect of moderator variables on variability in reliability estimations as effect size was examined by Analog ANOVA.
In the data analysis, reliability generalization based on meta-analysis was used. Of 95 Cronbach's Alpha coefficients obtained from 92 studies that were selected according to criteria were included in the meta-analysis. A number of criteria have been set to determine the studies to be included in meta-analysis. In addition, how different moderator variables affect reliability coefficients was examined. The purpose of this study was to analyze the meta-analytical reliability generalization of short form and long form of the Oxford Happiness Scale (OHS) for Turkish sample.
