Hoarding behavior, Insomnia, ADHD, Sleep patterns, Compulsive hoarding, Attention-deficit hyperactivity disorder, Sleep disorder-Psychological aspects
Previous research has provided evidence for the relationship between obsessive compulsive disorder (OCD) and sleep disturbances. However, the relationship between hoarding disorder, which was previously classified as a subset of OCD, and sleep disturbances has been given limited attention. In order to explore the relationship between insomnia and hoarding behavior, factors associated with these phenomenon, including depression, anxiety sensitivity, attention deficit/hyperactivity disorder (ADHD), and daily schedule, were explored in three separate studies. The first included 472 nonclinical participants who completed a set of questionnaires online including the Saving Inventory Revised (SIR), the Beck Depression Inventory (BDI), the Insomnia Severity Index (ISI), and the Anxiety Sensitivity Index (ASI). The second study included 149 nonclinical participants who completed a set of questionnaires online including the SIR, the ISI, the Depression, Anxiety and Stress Scale (DASS) and the Attention Deficit/Hyperactivity Disorder Symptoms Scale (ADHDSS), and the third included 31 participants who were recruited from the previous study and tracked their daily routines. Correlations and regressions performed in each of these studies provided further support for the relationship between insomnia and hoarding behavior, and suggested that depression, anxiety sensitivity, and attention deficit/hyperactivity disorder (ADHD) symptoms may all contribute significant variance to this relationship, such that when the regression controlled for ADHD and depression, insomnia was no longer a significant predictor of hoarding severity .
