Scoring

The International Personality Item Pool assessment consists of 120 items designed to evaluate personality traits across five major factors: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Each item corresponds to one of these factors and is further categorized into specific facet traits. The scoring process involves a 1–5 Likert scale, with items either positively or negatively keyed to ensure balanced measurement.

Positive and negative keyed items

Each item in the International Personality Item Pool is scored on a 1–5 Likert scale, with scoring dependent on whether the item is positively or negatively keyed.

For positively keyed items, the following scoring is applied:

• Very inaccurate = 1
• Moderately inaccurate = 2
• Neither inaccurate nor accurate = 3
• Moderately accurate = 4
• Very accurate = 5

For negatively keyed items, the scoring is reversed:

• Very inaccurate = 5
• Moderately inaccurate = 4
• Neither inaccurate nor accurate = 3
• Moderately accurate = 2
• Very accurate = 1

Personality factors

The items in the International Personality Item Pool are also divided into five personality factors, each further categorized into six facet traits. Each facet is represented by four specific items in the questionnaire.

• For Openness, the facets and corresponding item numbers are as follows: Imagination (3, 33, 63, 93), Artistic Interests (8, 38, 68, 98), Emotionality (13, 43, 73, 103), Adventurousness (18, 48, 78, 108), Intellect (23, 53, 83, 113), and Liberalism (28, 58, 88, 118). These facets explore an individual's creativity, curiosity, and willingness to embrace new experiences.
• The Conscientiousness factor is measured by the facets of Self-Efficacy (5, 35, 65, 95), Orderliness (10, 40, 70, 100), Dutifulness (15, 45, 75, 105), Achievement Striving (20, 50, 80, 110), Self-Discipline (25, 55, 85, 115), and Cautiousness (30, 60, 90, 120). These facets reflect an individual's ability to organize, plan, and regulate impulses.

These traits represent an individual's tendency to prioritize social harmony, kindness, and empathy in their interactions.

The facets include Anxiety (1, 31, 61, 91), Anger (6, 36, 66, 96), Depression (11, 41, 71, 101), Self-Consciousness (16, 46, 76, 106), Immoderation (21, 51, 81, 111), and Vulnerability (26, 56, 86, 116).

Next steps after using the International Personality Item Pool

The International Personality Item Pool assessment provides a structured framework for evaluating personality traits, offering valuable insights into an individual's characteristics and tendencies. However, interpreting and applying these results requires careful consideration to ensure they are meaningful and beneficial. Below are the recommended steps for professionals to maximize the utility of the IPIP assessment.

Review results

Identify patterns within the 5 personality traits for the understanding of patients' broad traits; for a more comprehensive assessment, identify patterns within facets. This can be done in both mental health settings and non-clinical environments to help practitioners gain insight into aspects of an individual’s personality.

Discuss results with patient

Professionals can open a sensitive and nonjudgmental conversation to discuss the results. The professional will try to get a well-rounded understanding of the patient, considering the broader context of the person and the social determinants surrounding them.

The results can be used as an aid for clinical formulations, this can help to guide professionals in targeted interventions that are specific to the individual and their needs. It can also be used alongside other psychological assessment tools to further aid clinical formulations.
