The construction of the Guilford-Martin Inventory of factors G-A-M-I-N

Abstract

Three hundred questionnaire items were constructed (these supposedly covered the behaviors composing the 5 traits) and administered to 250 men and 250 women college students. For item analysis of factors G, A, I, and N, extreme quarters of the distributions of scores were used as criterion groups. For factor M, the criterion groups were the 100 males scoring highest on the preliminary key for factor M and the 100 females scoring lowest on the key. Applying the Guilford abac method afforded scoring weights for each response to each item. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
