Welcome to the Insomnia Severity Index (ISI) Calculator! Because when it comes to insomnia, even our calculators can’t count sheep to fall asleep. 😴🐑

Formula for Calculating Insomnia Severity Index (ISI):

ISI = (Q1 + Q2 + Q3 + Q4 + Q5 + Q6 + Q7) / 7

Categories of Insomnia Severity

ISI Score Insomnia Severity
0-7 No clinically significant insomnia
8-14 Subthreshold insomnia
15-21 Clinical insomnia (moderate)
22-28 Clinical insomnia (severe)

Hilarious ISI Examples

Different Methods to Calculate ISI

Method Advantages Disadvantages Accuracy
ISI Questionnaire Direct assessment of insomnia severity Subjective and reliant on self-reporting Moderate
Polysomnography (Sleep Study) Provides objective sleep data Complex, costly, and not practical for all High
Actigraphy Monitors sleep patterns and disturbances May not provide detailed insomnia assessment Moderate

Limitations of ISI Calculation Accuracy

  • Subjective Responses: ISI relies on self-reporting and may not fully reflect actual sleep behavior.
  • Varied Perceptions: Individuals may interpret the severity of their insomnia differently.
  • Temporary Factors: External factors can influence ISI scores on a given day.

Alternative Methods for Measuring Insomnia Severity

Method Pros Cons
PSQI (Pittsburgh Sleep Quality Index) Comprehensive sleep assessment Requires a longer questionnaire
Athens Insomnia Scale Identifies insomnia severity and types May not be as widely used as ISI
Insomnia Diary Tracks sleep patterns over time Requires daily record-keeping
