| dc.description.abstract | Problematic substance use is one of the top disparities affecting Indigenous people.
Among non-Indigenous people, specific personality traits and drinking motives are associated
with problematic patterns of alcohol use. The Modified Drinking Motives Questionnaire –
Revised (MDMQ-R) is a measure for examining drinking motives among youth and adults.
Despite cross-cultural use, the MDMQ-R demonstrated a different factor structure among
Indigenous youth in Canada (Mushquash et al., 2014). The MDMQ-R has also been examined in
relation to personality traits, where findings suggest that specific personality traits and drinking
motives together are associated with problematic patterns of alcohol use. This study examined
the factor structure of the MDMQ-R in a substance use treatment-seeking sample of Indigenous
adults. Additionally, this study sought to understand how personality traits are related to
substance use motives. Sex differences regarding substance use motives were investigated as
well. As hypothesized, a three-factor structure solution received support, consistent with findings
among Indigenous youth. Hypotheses regarding personality traits were supported, whereby
positive reinforcement motives were associated with impulsivity and sensation-seeking traits,
and negative reinforcement motives were associated with hopelessness and anxiety sensitivity
traits. Sex was not predictive of higher scores on any MDMQ-R subscales. Examining the
MDMQ-R structure may provide culturally relevant information about the use of this measure with Indigenous populations in Canada. These findings may inform future research led by
Indigenous communities to understand better the needs of their members facing problematic
substance use. | en_US |
