Answer

Content Validity

Answer

Internal Consistency

Answer

Construct Validity

Question 2

A company uses the SPI as a pre-employment screening tool for a sales role. After one year, they find a strong positive correlation between high scores on the 'Ambition' scale and actual sales performance. This finding provides direct evidence for the scale's:

Question 3

Which of the following statistics is most commonly used to evaluate the internal consistency of a personality scale within the SPI, indicating how well the items on the scale measure a single, unified concept?

Accepted Answer

Cronbach's Alpha (α)

Answer

Pearson correlation coefficient (r)

Answer

Standard Error of Measurement (SEM)

Answer

T-score

Question 4

To establish the construct validity of the SPI's 'Sociability' scale, a research team administers it to a group along with another well-established test known to measure 'Gregariousness'. They find a high positive correlation between the two scales. This provides what specific type of validity evidence?

Accepted Answer

Convergent evidence

Answer

Discriminant evidence

Answer

Content-related evidence

Answer

Concurrent evidence

Question 5

During the initial development phase of the SPI, a panel of subject matter experts (SMEs) in personality psychology carefully reviews all proposed test questions. They are asked to rate each question on its relevance and representativeness of the specific personality facet it is intended to measure. This entire process is a critical step for establishing:

Accepted Answer

Content Validity

Answer
