We next compared the following in terms of their association with young adult depression: (a) conduct problems ever or conduct problem trajectory classes; (b) depression in late childhood or early adolescence (age 10 and 13 MFQ scores).
Both groups achieved a conduct problems score in the normal range (scores >3 are indicative of dysfunction), but girls in the high-DHA group scored significantly higher compared with girls in the standard-DHA group (see web appendix B).
But more importantly, they hoped to determine whether the kids were developing any "conduct problems" as a result of their drug use.
Following prior research[ 6], we also created a lifetime conduct problems scale and a composite index of antisocial behavior.
A Clinical Psychiatric Officer was available on sight to handle mental health emergencies and to make referrals to the Regional Referral Hospital in case of a mental health emergency such as severe depression or conduct problem with a potential for harm.
Due to a highly skewed distribution, the conduct problem score was natural logarithmically transformed to obtain a closer to normal distribution.
The internal consistency estimate for the present sample was acceptable (α = 0.76) and the five items were added to give a total conduct problems score.
For some analyses, we combined the three 'high' conduct problem trajectory classes (EOP, CL and AO) to create a 'conduct problems ever' category, and contrasted this with the 'low' class.
