The association between sleep and physical activity has on a group-level been well-documented but seems to vary between individuals. Research addressing the problems of group-to-individual generalizability and temporal aspects within-individuals has been called for. The aim of the present study was therefore to investigate sleep and physical activity as a unique dynamic system, through utilizing novel time series analysis to explore the person-specific changes occurring in an insomnia-prone participant undergoing a CBT-I treatment. Intensive longitudinal data were gathered from a single participant carrying an activity tracker and were investigated with time-varying vector autoregressive modeling (TV-VAR). The hypotheses were that changes would be identified in the autoregressive and cross-lagged parameters of the two variables over time. The autoregressive parameter of total sleep time (TST) was expected to decrease from positive to zero or negative. A positive cross-lagged effect of daytime physical activity on TST the following night was expected to appear over the course of the intervention, and finally, if a positive cross-lagged effect of TST on physical activity the following day was identified in the beginning of the intervention, this effect was expected to decrease over time. For this participant, a slight decrease in the autoregression of TST during the time of the intervention could be observed, but the change seen was statistically insignificant. A significant decrease in the intercept of TST was identified, and the positive association between daytime physical activity and TST of the following night disappeared over time. TST could significantly predict physical activity of the following day, but in a pattern opposite of the expected; less sleep predicted more physical activity the following day and vice versa. In conclusion, the results highlight the benefits of using intensive longitudinal data to identify unique, patient-specific processes that would have been overseen in group-level data. ... |
