Meteorosensitivity as a mediator between affective temperaments and insomnia among women

Abstract

BackgroundThe main purpose of this cross-sectional study was to evaluate the associations between affective temperaments and insomnia symptoms in women and to examine meteorosensitivity as a mediator in this relationship.Participants and procedureFor this study, 446 healthy women were recruited from a nonclinical population via an online recruitment platform. The participants’ ages ranged from 18 to 65 years (M = 29.67, SD = 8.39). The Polish version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire was used to assess affective temperaments (depressive, cyclothymic, hyperthymic, irritable and anxious). Meteorosensitivity was assessed through the Polish adaptation of the METEO-Q questionnaire. Insomnia was evaluated by the Athens Insomnia Scale.ResultsPositive correlations with insomnia were found for meteorosensitivity, depressive, cyclothymic, irritable, and anxious temperaments, while insomnia negatively correlated with hyperthymic temperament. Meteorosensitivity showed positive correlations with depressive, cyclothymic, irritable, and anxious temperaments. No correlation between me-teorosensitivity and hyperthymic temperament was found in the studied group. Based on the regression coefficients, meteorosensitivity, cyclothymic temperament and anxious temperament were found to be significant predictors of insomnia. Mediation analyses indicated that cyclothymic and anxious temperaments affected insomnia symptoms both directly and indirectly through meteorosensitivity as a mediator.ConclusionsThe results indicated a significant relationship between affective temperaments and insomnia symptoms, including the role of meteorosensitivity dimension as a mediator. These findings suggest that mood-related affective temper-aments can also be associated with meteorosensitivity and jointly affect the level of insomnia symptoms in women.
