Once these categories had been developed and defined, two authors (RS, MW) reviewed the transcripts and assigned each participant to a patterns of change category that in their judgment, best represented the participant's changes in alcohol use over the course of the study period.
The patterns of change in drug use will be presented using the same categories as in the changes in alcohol use (see above): Pattern A (no/low risky use → no/low risky use).
No changes in alcohol use or criminal involvement were obtained.
This study examined alcohol use from pre-adolescence to mid-adolescence and determined the influence of hypothesized covariates on changes in alcohol use rates during this developmental period.
13-year changes in alcohol use related to changes in fibrinogen.
As such, changes in alcohol use cannot be analysed using parametric statistical tests.
Changes in alcohol use disorders (AUDs) over time correlate with baseline levels of alcohol use (Dawson et al., 2007) and with major depression (Greenfield et al., 1998).
This may reflect a change in alcohol consumption patterns.
A change in alcohol consumption patterns associated with the GFC has been described in other countries [ 21].
This review also noted a general lack of evidence related to alcohol use patterns in contemporary adolescents.
