Had a great time joining my first podcast a few months back with Bethan for Optimism Sci! We chatted about research on sleep, emotions, and how social media and smartphones fit into the mix. 🛌📱😊

Overall, these findings suggest that sleep quality and adaptive emotion regulation hold independent roles in reducing emotional inertia. Both are key to emotional wellbeing, but don't rely on each other.

Emma Sullivan @emmacsullivan.bsky.social · Jan 6

Interestingly, the association between greater adaptive ER strategy use and lower NA inertia was observed regardless of participants' sleep quality.

Emma Sullivan @emmacsullivan.bsky.social · Jan 6

We found that better sleep quality was linked to lower NA inertia. In other words, good sleep helps reduce the persistence of negative affect over time.

Emma Sullivan @emmacsullivan.bsky.social · Jan 6

In this online study (N = 245), we used a validated film clip task to index NA inertia. Sleep quality and use of adaptive emotion regulation strategies were measured using questionnaires.

Emma Sullivan @emmacsullivan.bsky.social · Jan 6

We know that good sleep and using adaptive emotion regulation strategies can help reduce negative affect persistence (NA inertia). But do they work in concert to reduce NA inertia?

Emma Sullivan @emmacsullivan.bsky.social · Jan 6

Emotional inertia- when negative feelings persist over time- has been linked to poorer wellbeing. But we know little about the mechanisms underlying this link.

I'm excited to share that the second study of my PhD, exploring the links between emotion regulation, sleep quality, and emotional inertia, has been published in Cognition & Emotion!

Emotional inertia is independently associated with cognitive emotion regulation strategies and sleep quality*

Emotional inertia (i.e. the tendency for emotions to persist over time) is robustly associated with lower wellbeing. Yet, we know little about the mechanisms underlying this relationship. Good qual...

Is a sleep intervention delivered by non-expert practitioners feasible for youth mental health? https://buff.ly/4dRXRPP

Emma Sullivan finds that CBT for insomnia (delivered by assistant psychologists) is a feasible intervention for young people w mental health & sleep difficulties.
