Four distinct subtypes of adolescent impulsivity were identified via latent profile analysis, each variably associated with specific dimensions of sleep quality, suggesting targeted intervention strategies tailored to specific 'impulsivity subtype-sleep problem' profiles.
Key Findings
Results
Latent profile analysis identified four distinct subtypes of adolescent impulsivity in the sample.
The four subtypes were: mean-low (20.9%), balanced (29.9%), motor-impulsivity (33.9%), and unplanned-cognitive impulsivity (15.4%)
The study was conducted across 17 secondary schools in northeastern Sichuan Province using random cluster sampling
A total of 6,974 questionnaires were collected in this multicenter cross-sectional study
Impulsivity was measured using the Barratt Impulsiveness Scale (BIS-11) and latent profile analysis was conducted using Mplus 8.3
Results
The motor-impulsivity subtype was more strongly associated with subjective sleep quality compared to the unplanned-cognitive impulsivity subtype.
OR = 1.36, 95% CI: 1.228–1.504 for subjective sleep quality
Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI)
Multiple logistic regression was conducted using SPSS 24.0
The motor-impulsivity subtype was the largest group, comprising 33.9% of the sample
Results
The motor-impulsivity subtype showed a stronger association with sleep disturbance compared to the unplanned-cognitive impulsivity subtype.
OR = 1.59, 95% CI: 1.418–1.776 for sleep disturbance
This was the strongest odds ratio among the sleep dimensions examined for the motor-impulsivity subtype
Comparisons were made relative to the unplanned-cognitive impulsivity subtype as reference group
Results
The motor-impulsivity subtype was more strongly associated with daytime dysfunction compared to the unplanned-cognitive impulsivity subtype.
OR = 1.40, 95% CI: 1.293–1.513 for daytime dysfunction
Motor-impulsivity subtype showed significant associations across three sleep dimensions: subjective sleep quality, sleep disturbance, and daytime dysfunction
Motor-impulsivity was the most prevalent subtype at 33.9% of the sample
Results
The unplanned-cognitive impulsivity subtype uniquely showed significant correlations with sleep efficiency and sleep time.
OR = 0.81, 95% CI: 0.764–0.867 for sleep efficiency
OR = 0.88, 95% CI: 0.820–0.944 for sleep time
The direction of these odds ratios (below 1.0) indicates a distinct pattern compared to the motor-impulsivity subtype associations
The unplanned-cognitive impulsivity subtype comprised 15.4% of the sample, the smallest subtype
Results
Different subtypes of adolescent impulsivity were variably associated with specific dimensions of sleep quality rather than sleep quality as a unitary construct.
Motor-impulsivity was associated with subjective sleep quality, sleep disturbance, and daytime dysfunction
Unplanned-cognitive impulsivity was uniquely associated with sleep efficiency and sleep time
The mean-low and balanced subtypes served as comparison groups in the analysis
PSQI components assessed included subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbance, use of sleeping medication, and daytime dysfunction
What This Means
This research suggests that not all impulsive behavior in teenagers is the same — it can be broken down into at least four distinct patterns or 'subtypes.' Using data from nearly 7,000 middle and high school students across 17 schools in western China, researchers identified groups they labeled as mean-low, balanced, motor-impulsivity, and unplanned-cognitive impulsivity. Each of these groups had different relationships with specific aspects of sleep problems, rather than impulsivity simply being linked to 'bad sleep' in general.
Specifically, teenagers whose impulsivity was primarily expressed through physical or motor behavior (acting without thinking about physical actions) were more likely to report poor subjective sleep quality, more sleep disturbances during the night, and greater difficulty functioning during the day. In contrast, teenagers whose impulsivity was more related to poor planning and cognitive control showed a different pattern — they were more likely to have problems with sleep efficiency (the proportion of time in bed actually spent sleeping) and with total sleep time. This suggests these two types of impulsive teenagers are struggling with different kinds of sleep problems.
This research matters because it challenges a one-size-fits-all approach to addressing sleep and behavior problems in adolescents. Rather than treating 'impulsivity' and 'poor sleep' as single, uniform problems, these findings suggest that interventions might be more effective if they are tailored to match the specific type of impulsivity a teenager shows with the specific sleep problem they are most likely to experience. This could help schools, clinicians, and parents better target support for teenagers at risk.
