The Loneliness of Migraine Scale: A Development and Validation Study

Patients with migraine often isolate themselves during their attacks. This disease-related loneliness seems to reverberate interictal, as some patients report failing relationships, losing jobs, or suffering from reduced social contacts. We developed a 10-item self-report questionnaire, the loneliness of migraine scale (LMS), and conducted an online survey. The questionnaire comprised diagnostic questions for migraine, the loneliness of migraine scale, the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-8), and the Headache Attributed Lost Time Index (HALT-90). We computed item statistics, the psychometric properties of the LMS and assessed correlations between loneliness, migraine days, anxiety, and depression. We included 223 participants with (probable) migraine, reporting 8 ± 6 headache days with a disease duration of 11 ± 11 years. The mean scores of the HALT were 88 ± 52, of the GAD-7 10 ± 5, for PHQ-8 11 ± 6, and of the LMS 28.79 ± 9.72. Cronbach’s alpha for all ten items was 0.929. The loneliness scale correlated with the GAD-7 (r = 0.713, p < 0.001), with the PHQ-8 scale (r = 0.777, p < 0.001) and with migraine days (r = 0.338, p < 0.001). The LMS is a reliable and valid questionnaire measuring the loneliness of migraine patients. Feelings of loneliness were common and correlated highly with migraine days, anxiety, and depression.
