This is a relatively early adolescent sample, as 46.9% of the sample was aged 12 at their baseline assessment. The interval between participants’ baseline assessment and their first follow-up assessment was, on average, 2.08 years (SD = .55). For simplicity, we refer to the baseline assessment and first follow-up assessment as Time 1 (T1) and Time 2 (T2), respectively, from this point forward.
