MS Self-Report Questionnaires: Fatigue and Sexual Function

Self-Report Questionnaires

Self-report questionnaires are used to measure a person’s perception of his/her own experiences and understanding of events. The purpose is to help individuals evaluate their health, emotions and/or experiences. The self-report evaluations can help people organize their experiences in a more meaningful way that can be shared with their healthcare providers. The reports create an opportunity to communicate sensitive topics with healthcare providers in a less threatening manner. Healthcare providers can then review the self assessments with their patients and if needed provide appropriate medical interventions.

There are several self-report questionnaires that are directly related to helping people with MS evaluate their condition and experiences. The Fatigue Severity Scale (FSS) and the MS Intimacy and Sexuality Questionnaire-19 (MSISQ-19) are two examples of self-report surveys that can help people with MS evaluate their levels of disease experiences. The results can then be shared with healthcare providers to help manage disease symptoms of MS. This document contains these two self-report questionnaires.

Fatigue Severity Scale (FSS)

Fatigue is recognized as the most common symptom experienced by people with MS. Some studies indicate that fatigue affects approximately 85% of the MS population and nearly 66% of this population experiences it daily. The Fatigue Severity Scale (FSS) was developed by Lauren Krupp, MD, a neurologist who specializes in MS, to address this overwhelming MS symptom. She and her colleagues designed a self-report survey that patients could complete and bring to appointments that would help providers in recognizing and diagnosing fatigue related symptoms of MS.

The self-report questionnaire is a 9 question survey that takes approximately 5 minutes to complete and score. This short survey can provide a wealth of clinical information on the severity of fatigue symptoms. The questionnaire addresses fatigue symptoms as they relate to physical functioning, exercise and work, and family or social life. The scoring is based on a scale ranging from 1 (strongly disagree with the statement) to 7 (strongly agree with the statement). The results are easy to score. The score is based upon an average of the responses to the questions (add up the circled number from each question and then divide by nine). The final number can then be compared to other diseases that are associated with fatigue. The final score is a good indicator of how each person rates their level of fatigue. This information should be shared with healthcare providers so appropriate interventions can be made.

Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19)

The effects of MS on intimacy and sexual functioning are a common problem. This problem affects nearly 91% of men and 80% of women who have MS. In addition to the problems of sexual dysfunction there tends to be a problem of sharing this concern with healthcare providers. To address this sensitive topic and to open dialog between people with sexual function problems and with their healthcare providers, Frederick Foley, PhD and Audrey Sanders, PhD developed a self-report questionnaire for patients. Drs. Foley and Sanders and their colleagues designed a 19 question self-report survey that people with MS could complete and then bring to their healthcare providers. The questionnaire addresses primary, secondary, and tertiary effects of MS on sexual functioning. The primary effects are related to impaired genital sensation and/or decreased sexual drive. The secondary effects focus on fatigue, bladder problems, and spasticity or muscle tightness. The tertiary effects are related to psychological distress and overall well-being like depression and feelings of a negative self-image. These three levels of functioning can have a negative impact on intimacy and sexual functioning.

The self-report questionnaire is a 19 question survey that takes approximately 15 minutes to complete. This survey provides the opportunity for people with MS who are having sexual functioning problems to address their concerns about sexuality and intimacy. The scoring is based on a scale ranging from 1 (never interfered with my sexual activity or satisfaction) to 5 (always interfered with my sexual activity or satisfaction). Questions are answered by placing a check mark in the number box that best corresponds with each person’s experience. The survey authors recommend that any question that is marked with a 4 or 5 should be discussed with providers. This survey can help healthcare providers address appropriate interventions for symptom management of sexual functioning concerns. 

MS Intimacy and Sexuality Questionnaire-19




The self-report questionnaires are designed to help people organize their thoughts and feelings about health concerns. The questionnaires should be considered tools that will help the patient and provider identify medical and other issues that can affect people with MS. They are not designed to diagnose a particular problem but to increase the understanding of MS symptoms and their relationship to each individual. It is important that patients share results from self-report surveys with their healthcare providers. Sharing results of self-report questionnaires can increase treatment effectiveness on symptom management.
