The STRAIN, or Stress and Adversity Inventory, is a NIMH/RDoC-recommended instrument that efficiently and reliably assesses a person’s cumulative exposure to life stress. The measure is entirely online and systematically inquires about a diverse array of acute life events (e.g., deaths of relatives, job losses, negative health events) and chronic difficulties (e.g., ongoing health problems, work problems, relationship problems, financial problems, etc.) that have implications for human health and well-being. Stressors occurring in early life (e.g., childhood maltreatment or neglect, parental loss/separation, etc.) are also queried in detail. Respondents are asked to rate the severity, frequency, timing, and duration of each stressor they endorse. Questions that are inappropriate (based on a participant’s demographic characteristics) are automatically omitted from the interview (e.g., female reproductive health questions for male participants, questions about children for persons without children). The instrument can be self-administered by users at a computer or can be administered by an interviewer who follows the simple on-screen prompts. Because the STRAIN is embedded in an automated, online interviewing environment, the interview can be completed almost anywhere, including in a clinic, research laboratory, or classroom. Presently, we have an adolescent version of the STRAIN (Adolescent STRAIN) and an adult version (Adult STRAIN), both of which are available in several languages (see below). Although the STRAIN was originally designed to assess stressors occurring over the entire lifespan, we have since developed additional versions that focus on the same stressors but over shorter time periods (e.g., past 6 months, past year; see below). To begin using the STRAIN, complete the STRAIN Setup Form.
The average time needed to complete the STRAIN is 18-25 minutes, depending on the population being interviewed. Because there are multiple follow-up questions for each endorsed stressor (i.e., that assess severity, frequency, timing, and duration), there are approximately 220 questions that can be asked in all. Based on this information, the system produces 455 variables that are used to assess an individual’s cumulative exposure to stress. Using this raw data, we can presently create more than 115 different cumulative life stress summary variables and life charts that summarize a person’s stress exposure. Analyses can in turn be based on a number of factors, including stressor severity and/or the timing of stress exposure (e.g., Early Adversity vs. Distant vs. Recent Life Stress). More sophisticated analyses can be performed by focusing on stressors occurring in particular life domains (e.g., Housing, Education, Work, Health, Marital/Partner) or that have particular core characteristics (e.g., Interpersonal Loss, Physical Danger, Humiliation, Entrapment, Role Change).
Other interview-based measures have been developed for assessing life stress that require an independent rating team. The STRAIN is not a substitute for these more involved systems but rather is an alternative that can be used when the goal is to collect substantial information about health-relevant stressors in a relatively quick, efficient, and reliable manner. The STRAIN accomplishes this goal by combining the sophistication of an interview-based measure of life stress with the simplicity of a self-report instrument.
