    Studysummary This study found that adults with trichotillomania or skin picking disorder experienced significantly poorer sleep quality, which was linked to various factors including age, stress, distress tolerance, impulsivity, and comorbid mental disorders. Our plain-language summary of this paper — not a Tressless recommendation.
    The study investigated sleep quality in individuals with trichotillomania (TTM) and skin picking disorder (SPD), including 150 participants (75 with TTM and 75 with SPD). It found that both conditions were associated with significantly poorer sleep quality compared to the general population. The severity of these disorders correlated with the degree of sleep disturbance, emphasizing the importance of addressing sleep issues in treatment. Poor sleep quality was linked to higher perceived stress, lower distress tolerance, and greater impulsivity. The study underscored the need for further research to explore the mechanisms linking these disorders with sleep quality.
