How do you score on tests given to people with insomniaYou may know you’ve got insomnia. But could you prove it?

There is no lab test for insomnia that would back you up.

An overnight sleep study, then?

Maybe—but probably not. Sleep studies don’t discriminate very well between insomniacs and good sleepers.

Genetic factors?

There may be genetic markers associated with insomnia, but researchers have no definitive understanding of what they are or how they add up to insomnia. The diagnosis of insomnia disorder is still made subjectively, based on questions and answers about sleep.

The list of questions doctors often ask to make the determination is fairly short and sweet.  But researchers use pencil-and-paper tests to assess different aspects of sleep: sleep quality, insomnia severity, sleep reactivity, and sleep-related beliefs. If you’re unfamiliar with these questionnaires, you may find it interesting to look at them and see how you score.

At the Doctor’s Office

If you take your complaints about sleep to the doctor, he or she may attempt to rule out other disorders before asking questions related to insomnia. You’ll get a diagnosis of insomnia disorder if

  • you have trouble falling or staying asleep, or sleep that doesn’t feel restorative, at least 3 times a week,
  • your sleep problem has persisted for at least 3 months, and
  • you experience impairment(s) during the daytime: moodiness, for example, or trouble concentrating or a lack of stamina that interferes with social, occupational, and other types of functioning.

Researchers, however, use pencil-and-paper assessment tools to evaluate subjects’ sleep and sleep improvements. Following are some of these questionnaires, downloadable as PDF files.

Pittsburgh Sleep Quality Index (PSQI)

In 1989 University of Pittsburgh sleep scientists introduced the PSQI in an attempt to quantify an aspect of sleep acknowledged to be important but difficult to measure.

The scoring of the PSQI questionnaire—with 19 self-rated questions—is a bit involved, but explicit scoring instructions are given at the end of the test. (Five more questions are to be answered by your bed partner or roommate if you have one. But these questions are not scored.) The 19 self-rated questions are divided into 7 “component” scores. The component scores are then added together to get the global score, which can range from 0 to 21. A global score of over 5 is indicative of poor sleep quality.

Sample question: During the past month, how often have you had trouble sleeping because you wake up in the middle of the night or early morning?

Insomnia Severity Index (ISI)

Some people experience insomnia occasionally while others experience it practically every night. The severity of a person’s insomnia may predict how likely he or she is to respond to various treatments. So it’s seen as a key variable to take into account when diagnosing insomnia and recommending a treatment, and when assessing improvements in study participants’ sleep.

Scores on this 7-item ISI questionnaire range from 0 to 28. Trouble sleeping is considered to be severe enough to warrant a diagnosis of insomnia disorder if scores are 8 or higher.

Sample question: How worried/distressed are you about your current sleep problem?

Ford Insomnia Response to Stress Test (FIRST)

The FIRST is the newest of the tests, introduced in 2004. This questionnaire is said to measure people’s overall level of “sleep reactivity,” a trait hypothesized to increase the likelihood of a person’s sleep being disturbed during stressful situations. The claim is that people who score higher on the FIRST are more likely to develop persistent insomnia.

FIRST scores range from 9 to 36. Scores of 20 and above indicate that stressful situations experienced prior to sleep—or the anticipation of stressful situations ahead—may routinely knock your sleep off track and make you vulnerable to chronic insomnia. Access this questionnaire by looking at Table 1 on the third page of this article about stress-related sleep disturbance.

Sample questions: How likely is it for you to have difficulty sleeping (a) after an argument? (b) before having to speak in public?

Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS)

If you don’t sleep well, you may find yourself having negative thoughts about sleep. Over time, these thoughts may coalesce into ideas, attitudes, and beliefs about sleep that give rise physiological arousal, making it harder TO sleep. In turn, the sensations of increased warmth, muscle tension, and faster heart rate that accompany arousal reinforce the negative thoughts, giving rise to a vicious circle.

The 16-item DBAS identifies misconceptions about sleep and assesses how big a role these and other cognitive factors likely play in perpetuating a person’s insomnia. A high score suggests that dysfunctional beliefs and attitudes may be a significant component of your insomnia, amenable to treatment with cognitive therapies.

Sample item: When I sleep poorly on one night, I know it will disturb my sleep schedule for the whole week.

  1. I scored 24 on ISI 😦 What can I do? I tried seeing a psychiatrist, psychotherapist, a hypnotherapist and I dread sleep exactly the way you described it. I fear going to bed.

    CBT-i is so expensive in here, this also causes stress for me, cause I feel helpless and hopeless.

    1. Hi Jelena,

      I’m sorry to hear about your sleep problem and your high score on the ISI. You sound frustrated and scared, and that’s not a good place to be. But help is out there.

      I’d suggest you go through CBT-I because it’s now considered to be the most effective treatment for people with insomnia. Wherever you are, it may be that going through therapy with a behavioral sleep specialist would be too expensive.

      But there are several good CBT-I programs offered online, and they are fairly inexpensive. Here are three:

      https://www.sleepio.com/
      http://www.myshuti.com/
      http://www.cbtforinsomnia.com/

      If you live in the U.S., you could also go to the public library and check out some good books on CBT-I for free (and they might be available in other countries, too):

      The Insomnia Workbook, by Stephanie Silberman
      The Insomnia Answer, by Glovinsky and Spielman
      Overcoming Insomnia, by Edinger and Carney

      These books would lead you step by step through the CBT-I process.

      My book, The Savvy Insomniac, has a chapter on CBT-I, chapter 8. In it, I document my experience of going through CBT-I and the experience of 4 other insomnia sufferers who went through treatment with me. It might be helpful for you, particularly if you have a fear of sleeplessness or are anxious about trying sleep restriction therapy (usually offered as a part of CBT-I).

      There are many inexpensive ways to go through CBT-I. I hope you try one, because chances are you’ll benefit a lot.

      1. Thank you so much for getting back in touch!
        I will check all the books you recommend and will try to download yours on my Kindle. I live in Ireland, but hopefully they will be available here as well.

        Thank you again, and I hope I will succeeded in beating my fears!
        I
