Worry and anger are associated with latent classes of problematic smartphone use severity among college students.

BACKGROUND

Problematic smartphone use (PSU) is associated with depression and anxiety symptom severity throughout the literature. However, many important psychopathology constructs have not been examined for associations with PSU severity. Worry and anger are two psychopathology constructs receiving little empirical scrutiny in relation to PSU, but theoretically should demonstrate significant relationships. Furthermore, few studies have used person-centered analyses, such as mixture modeling, to analyze possible latent subgroups of individuals based on PSU symptom ratings.

METHOD

We conducted a web survey of 300 American college students, using the Smartphone Addiction Scale-Short Version, Penn State Worry Questionnaire-Abbreviated Version, and Dimensions of Anger Reactions-5 Scale.

RESULTS

Conducting mixture modeling using latent profile analysis, we found most support for a three-class model of latent groups of individuals based on their PSU item ratings. Adjusting for age and sex, worry and anger scores were significantly higher in the more severe PSU classes.

DISCUSSION

Results are discussed in the context of uses and gratifications theory, as well as compensatory internet use theory, in terms of individual differences explaining excessive technology use.

LIMITATIONS

Limitations include the non-clinical nature of the sample.

CONCLUSIONS

Worry and anger may be helpful constructs in understanding the phenomenology of PSU, and psychological interventions for worry and anger may offset PSU.
