Seasonal sensitivity in a high-latitude population and its relationship to adaptation variables and style of seasonal work organization

Abstract

This study is intended to determine the frequency of seasonal sensitivity in a sample of a Chilean high latitude (extreme southerly) population, and its correlation with labor activities involved in several types of shift work, with variables of general adaptation. A total of 465 participants took part in answering questionnaires to measure seasonality impacts through SPAQ (Seasonal Pattern Assessment Questionnaire), subjective happiness (Oxford scale), social adaptation (Bell), and anxiety and depression (MASQE30). The principal results indicate that the frequency of seasonal sensitivity in this sample was high, in a moderate level near the upper limit, and this is considered to have a significantly negative impact on daily life. Regarding seasonal patterns, the most common effect was in the summer profile, suggesting that people perceive benefits with the increase in sunlight, which correlates negatively with happiness. The analysis according to work-shift shows differential profiles for each one. These results are discussed relative to the importance for development of public policies to further the physical and mental health of extreme-southern populations.
