these findings provide further evidence that the isi is a reliable and valid instrument to detect cases of insomnia in the population and is sensitive to treatment response in clinical patients. ).10,15–17 the insomnia severity index (isi) is a brief instrument that was designed to assess the severity of both nighttime and daytime components of insomnia. two samples were thus formed for the present paper: a community sample including 959 individuals (with and without insomnia) selected from the adult population to participate in the epidemiological study,22,23 and a clinical sample, including 183 individuals with insomnia enrolled in a treatment study21 and 62 healthy controls (without insomnia) enrolled in one of several cross-sectional studies. participants (with and without insomnia) in the clinical sample completed a daily sleep diary24 for a 2-week period as part of their initial evaluation. criterion validity was examined by comparing agreements between the classification of patients as insomniacs or good sleepers based on the original isi cutoff scores (i.e., < 8, no insomnia, 8–14, sub-threshold insomnia, > 14, moderate to severe insomnia) and the classification of patients derived from an external criterion (i.e., the semi-structured interview for the clinical sample and the response to a yes-no question from the survey assessing the presence of sleep difficulties for the community sample).
these results are not unexpected given the clinical nature of the sample (all participants met criteria for an insomnia diagnosis). a subsample of 146 participants from the clinical sample who received treatment completed the isi before and after treatment. a cutoff score of 10 appears to be the best compromise to achieve optimal balance between sensitivity and specificity in a population-based sample. the measurement of insomnia remains a challenge for clinicians and investigators. likewise, with the upcoming dsm-v and expanded focus on dimensional assessment, instruments assessing insomnia symptoms along several dimensions (severity, duration, impact) may prove most helpful to assist clinicians in making a diagnosis.
the study comprised 16,401 participants without chronic spinal pain at baseline who were followed for â¼11 years. subthreshold insomnia comprised those with only daytime impairment or one or more nighttime symptoms.
in multivariable regression analysis using people without insomnia as reference, people with subthreshold insomnia or insomnia had relative risks (rrs) of chronic spinal pain of 1.29 (95% confidence interval [ci] 1.21â1.38) and 1.50 (95% ci 1.34â1.68), respectively. the rrs for people with one nighttime symptom were 1.30 (95% ci 0.83â2.05) for waso-insomnia, 1.32 (95% ci 1.06â1.65) for ema-insomnia, and 1.70 (95% ci 1.32â2.18) for sol-insomnia, respectively. these findings suggest that the risk of chronic spinal pain is highest among persons with insomnia subtypes characterized by sleep onset latency or among those having insomnia symptoms in all parts of the sleep period.
some suggestions based on your insomnia severity index total score: if you fit in the ‘no clinically significant insomnia’ or ‘subthreshold insomnia’ individuals with scores at the subthreshold level (8-14) were about equally divided between those with (44%) and without sleep difficulties (56%). people were categorized into ‘no insomnia symptoms’, ‘subthreshold insomnia’, and ‘insomnia’. subthreshold insomnia comprised those with only daytime, insomnia severity index, insomnia severity index, insomnia severity index score, insomnia severity index score interpretation, insomnia severity index (isi) pdf.
