Why the study?

While poor sleep is linked to higher risk of non-suicidal self-injury, the influence of non-suicidal self-injury on sleep patterns remained uninvestigated.

Does past non-suicidal self-injury predict current non-suicidal self-injury and poor sleep in adults?

Population

2374 adults

Comparison

Past non-suicidal self-injury exposure and associations with current non-suicidal self-injury and sleep patterns

Design

Cross-sectional and quasi-longitudinal study

Overview

Hypothesis-generating for sleep-NSSI links in young adults; leaves open causality and needs longitudinal confirmation before practice implications.

Structured PICO

Does past non-suicidal self-injury predict current non-suicidal self-injury and poor sleep in adults?

P
Population
2374 adults, mean age 27.58 years, 39.6% female
I
Intervention
Past non-suicidal self-injury (NSSI)
O
Outcome
Current non-suicidal self-injury (NSSI) and current subjective sleep patternspatient reported

Past non-suicidal self-injury is a strong predictor of current self-injury, whereas poor sleep has only a modest association.
