Inventory of Psychosocial Functioning (IPF)


Inventory of Psychosocial Functioning (IPF)


The IPF is an 80-item self-report instrument measuring PTSD-related functional impairment in the past 30 days. There are seven functional domains evaluated: romantic relationships, family relationships, work, friendships and socializing, parenting, education, and self-care. The IPF was developed to have high content validity, to not confound PTSD symptoms and related impairment, and to not require respondent attributions regarding the cause of impairment.

An abridged 7-item Brief Inventory of Psychosocial Functioning (B-IPF) is also available. This shorter instrument assesses PTSD-related functional impairment in the prior 30 days across the same domains that are assessed by the 80-item version of the IPF; each item on the B-IPF corresponds to one IPF functional domain.

Administration and Scoring

Both the IPF and the B-IPF are self-report measures suitable for clinical and research purposes.p>

For the IPF, respondents are asked a dichotomous yes/no question about the applicability of each domain in the past 30 days. If a functional domain is relevant, the respondent answers each question in that domain on a Likert-type scale ranging from 0="Never" to 6="Always".

Each domain scale is scored independently by summing all completed items (correcting for reverse coded items), dividing the total by the maximum possible domain scale score for the items included, and multiplying by 100. Each domain scale yields a score ranging from 0-100, with higher scores indicating greater impairment. As respondents only complete the domain scales that apply to them, to calculate the overall IPF score, the sum of all the completed IPF scale scores is divided by the number of scales completed.

As with the IPF, respondents only answer questions on the B-IPF pertaining to domains that have been relevant in the past 30 days. The B-IPF total score is calculated by summing the scale items completed by the respondent, dividing by the maximum possible score based upon the number of applicable items and multiplying by 100. B-IPF total scores represent an index of overall functional impairment, with higher scores indicating greater functional impairment.

Information about cutoff score ranges is included in the referenced articles below.

Sample Item

  • Item: [If the respondent has been in contact with friends in the past 30 days] I was willing to meet new people.
  • Response: 7-point Likert-type scale (0 = "Never"; 1-5 = "Sometimes"; 6 = "Always")
