So, What is the mYti© questionnaire?

mYti© is a personality and motivations assessment that provides insight into the way an individual gets things done and the way they behave under certain circumstances. Our assessment is not an aptitude test, but rather a questionnaire that allows the individual to position themselves. Often times tests are black and white and answering a question incorrectly means failing the test. There are no "wrong" answers with this assessment. What makes mYti© unique is that no two test results are the same. At Talentoday we believe each and every person is unique.

The psychometrics behind the questionnaire


The mYti© questionnaire, uses ipsative or "forced choice" questions: users are asked to choose between two options based on their personal preferences. This questionnaire format offers the dual advantage of minimizing acceptance and social desirability biases. Because there is no "right answer", the results accurately reflect the specific characteristic of the individual user and are free from social acceptance biases.


We cross-referenced the answers to the questionnaire's 128 questions in order to confirm their internal consistency. We then developed 28 personality and motivation criteria based on these results.

The 20 personality criteria were divided into 5 major categories, which we consider essential to a person's professional life: Communicate, Manage, Dare, Adapt, and Excel.

Scientific validation

The stability of Talentoday's mYti© tool is essential to obtaining reliable, consistent measurements. We have therefore taken measures to confirm the questionnaire's validity, accuracy and sensitivity.


The questionnaire results were calibrated using a large sample, which allowed us to standardize and ensure the psychometric validity of these results. Thanks to the quality of our database, the most recent calibration was conducted with a sample of 2,350,430 individuals.

We also calibrate to take into account differences due to cultural biases and due to the language in which the questionnaire was taken. We analyzed the trends by taking into account the respective cultures of each country in order to standardize and adapt their respective translations.

Internal consistency

Internal consistency evaluates the accuracy and reliability of a test, which is measured by Cronbach's alpha (1951) See: Cronbach's Alpha. This assessment tool is a calculation method for the covariance of the items and questions for each criterion, allowing us to measure their homogeneity. The higher the covariance, the more the obtained score corresponds to the measured data.

Cronbach's alpha is calculated using the following:

is the number of questions (items)

is the variance of the question's variance of a personality or motivation trait

is the variance of the question (item), i

The American Psychological Association recommends alpha greater or equal than 0.7. All the items in Talentoday's mYti© questionnaire have a Cronbach's alpha greater than 0.7.

The average alpha for each item in the questionnaire is 0.74.


The questionnaire's stability is measured by the consistency of the variance between an individual's results the first time t1 and the second time t2 taking the test. This test-retest method makes it possible to calculate a correlation coefficient r between the two assessments, t1 and t2. According to the American Psychological Association's recommendations, if this coefficient is high enough (r greater than 0.6), that means that the results were stable over the course of the subsequent six-month period, as defined by the personality and motivation measurements.

Note that after six months, certain criteria may change.

Test-retest analysis methodology:

  • Administer a test to a sample of users.
  • Re-administer the same test to the same group, six months later.
  • Calculate the correlation coefficients of the collected results.

We confirmed that the 28 mYti© criteria all presented a correlation greater than 0.6 in the retest at six months.

Predictive validity

A test is valid if it measures what it is supposed to measure. This validity defines the meaning of the scores: they reflect what they are supposed to measure, no more no less. Thanks to this validity, we can draw specific conclusions about an individual based on their score - in this case their personality and motivations.

A predictive validity study compares the results from the psychometric assessment tool and an external assessment index. We therefore calculated the correlation between the mYti© score and a second score, which evaluates the same measurements using a different method.

Predictive validity analysis methodology:

  • Administer the mYti© questionnaire to a sample of subjects.
  • Next, ask the managers of these subjects to assess them using a second questionnaire that evaluates the same measurements.
  • Finally, ask each subject to conduct a self-assessment using the second questionnaire.

After analyzing and comparing the results, the relationship between the mYti© scores, the managers' assessment scores and the self-assessment scores indicates a high degree of predictive validity.

Representativity of the dataset


Talentoday has a pool of over three million assessed candidates. Users are of all ages and categories: adolescents, students, employees, job seekers, and retirees. 160 nationalities are represented in this data.

People have taken the Talentoday questionnaire from from all over the world: America, Europe, Asia, Oceania, and Africa.

The sample meets representative criteria: 142 companies with over 200 employees (Apple, IBM, Walmart, etc.) and 402 universities with over 1,000 students (University of California, Berkeley, National University of Singapore, etc.). This diversity allows us to apply individual analysis to an extensive pool of candidates - the starting point for large-scale psychometrics.
