Use of the 50-item International Personality Item Pool-Five Factor Model measure (Goldberg, 1999) can be a hindrance for researchers when dealing with participants that are less than enthusiastic about completing long questionnaires. The Mini-IPIP scales was developed specifically for this purpose. This newly developed assessment has been shown equally reliable and valid across the five measures in only 20-items.
The Mini-IPIP Personality Scale (Donnellan et al., 2006) is a derivative of the 50-item IPIP-FFM (Goldberg, 1999). It was published by the APA in the journal article presented in Psychological Assessments (Donnellan et al., 2006) that introduced the assessment tool. The Mini-IPIP is not available from any other source and does not have an online availability (apart from researcher published sites used for this specific research). Like the other assessments derived from the IPIP, it is in the public domain. Therefore, it has no cost associated with administration and it is self-scored with no means of electronic scoring at this time.
The Mini-IPIP (Donnellan et al., 2006) tests Big Five factors of personality; Extroversion, Agreeableness, Conscientiousness, Neuroticism and Intellect/Imagination. It uses a Likert scale in answering 20 items designed to predict levels of each of the five factors. The IPIP-FFM (Goldberg, 1999) 50-item questionnaire is one of many “short” forms of the more comprehensive IPIP-NEO containing 300 items used for the same purpose. Gosling, Rentfrow and Swann (2003) reduced the measure to only ten items creating the Ten-Item Personality Inventory (TIPI) noting a loss in psychometric quality. Donnellan (2006) sought to create the Mini-IPIP in order to slim down the 300-item original to only 20 items while still maintaining the reliability and validity represented in the other Five Factor Models. Its primary use is for research purposes where participants would already have multiple assessments to complete and/or limited time to complete the assessment. It could have potential use as a practical assessment tool in conceptualizing and treatment planning where several assessments may be used and clients are short on patience for such tools.
The Mini-IPIP (Donnellan et al., 2006) is a 20-item assessment used to measure levels of the Big Five Personality Factors. In the longer IPIP-FFM, there are ten items for each factor. The Mini-IPIP gleaned four items to represent each factor. It tests Extroversion (i.e. Am the life of the party), Agreeableness (i.e. Sympathize with others’ feelings), Conscientiousness (i.e. Get chores done right away), Neuroticism (i.e. Have frequent mood swings) and Intellect/Imagination (i.e. Have a vivid imagination). It is a self-report inventory and answered via a five point Likert scale which, in turn, is administrator scored. While there are no published qualifications to administer this assessment, one can assume that some...
