Study Finds Alexithymia Linked to Insomnia in Female Teens with Depression

Reading Time: 2 minutes

A recent study has made significant strides in understanding the complex relationships between insomnia, alexithymia (the difficulty in identifying and expressing emotions), and major depressive disorder (MDD) in adolescents.

The research focused on the prevalence and associated factors of insomnia in Chinese adolescents diagnosed with MDD, with a particular emphasis on exploring the differences between male and female adolescents. The findings were published in the journal Psychology Research and Behavior Management

The study involved 329 adolescents diagnosed with MDD, drawn from seven hospitals in Anhui Province, China, between October 2020 and April 2022. The researchers used the Insomnia Severity Index Scale (ISI), the 20-item Toronto Alexithymia Scale (TAS-20), and the Center for Epidemiologic Studies of Depression Scale (CES-D) to assess insomnia, alexithymia, and depression symptoms, respectively.

The findings revealed that insomnia was prevalent among the participants, with no significant sex differences observed in its rates. However, the relationship between alexithymia and insomnia showed variation between the sexes. In female adolescents, alexithymia was significantly associated with insomnia, highlighting the need for tailored treatment strategies focusing on emotional regulation capabilities. This association was not observed in male adolescents.

Moreover, the study shed light on the various factors correlating with insomnia in adolescents with MDD, such as family relationships, perceived academic stress, and higher levels of depression and alexithymia. Particularly in female patients, both alexithymia and depression symptoms were found to be significant factors associated with insomnia, underscoring the intricate interplay between these conditions.

This research is pivotal in understanding the psychopathological mechanisms of insomnia in adolescents with MDD and underscores the importance of considering alexithymia in psychological interventions and treatments. It contributes to a more nuanced understanding of the gender differences in mental health issues among adolescents and the complex interplay between sleep disturbances, emotional processing, and depression. The findings have significant implications for developing more effective and targeted therapeutic strategies for managing insomnia in adolescents with MDD, particularly in addressing the emotional regulation capabilities in this demographic.

The study’s conclusions emphasise the critical role of alexithymia, especially in female adolescents with MDD, as a significant risk factor for insomnia. It points towards the need for future treatments of insomnia in adolescent MDD patients to design programmes that improve the ability of emotional regulation, thus providing new insights into the psychopathological mechanisms, treatments, and psychological interventions in adolescents with MDD.
