Up to 16 weeks
Secondary Outcomes (3)

Study Arms (2)
Cohort 1: Juvenile Psoriatic Arthritis (jPsA)
EXPERIMENTALParticipants (aged greater than or equal to \[\>=\] 5 to less than \[\<\] 18 years) will receive ustekinumab at the dose and frequency as prescribed by their treating health care professional (HCP).
Cohort 2: Pediatric Psoriasis (PsO)
EXPERIMENTALParticipants (aged \>=6 to \<18 years) will receive ustekinumab at the dose and frequency as prescribed by their treating HCP.
Interventions
This study does not provide dosing instructions for ustekinumab but will engage participants who have been treated with ustekinumab by their corresponding HCPs independent of this study.
Eligibility Criteria
You may qualify if:
- Greater than or equal to (\>=) 5 to less than (\<) 18 years of age, inclusive, with a diagnosis of juvenile psoriatic arthritis (jPsA) (that is, International League Against Rheumatism \[ILAR\] or Vancouver criteria) by qualified health care professional (HCP)
- \>=6 to \<18 years of age, inclusive, with a diagnosis of pediatric psoriasis (PsO) by a qualified HCP
- Initiated ustekinumab treatment \>=16 weeks prior to enrollment and received 3 or more doses of ustekinumab prior to enrollment
- Parent(s) (preferably both if available or as per local requirements) (or their legally acceptable representative) must sign an informed consent form (ICF) indicating that he or she understands the purpose of, and procedures required for, the study and is willing to allow the child to participate in the study. Assent is also required of children capable of understanding the nature of the study (typically 7 years of age and older) as described in informed consent process
You may not qualify if:
- Has poor tolerability of venipuncture or lack of adequate venous access for required blood sampling
- Has any condition that, in the opinion of the investigator, participation would not be in the best interest of the participant (example, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments
