A major challenge in linking conservation science and policy is deciding how, and when, to offer relevant science to decision-makers to have the greatest impact on decisions. This chapter argues it is a question of alignment – of selecting the right knowledge to address the needs of decision-makers, ensuring that knowledge is accessible to them, and articulating it within their decision-making processes. The chapter describes three mechanisms to enhance this alignment: decision support tools; active knowledge exchange mechanisms; and large-scale scientific assessments. For each, we provide examples and draw out guidelines regarding circumstances in which the mechanism is likely to be most effective. No single mechanism is consistently best at aligning evidence with policy and practice. Each has strengths and weaknesses, and can be applied in different circumstances and at different scales. The chapter ends with a call for these mechanisms that link synthesised evidence with policy and practice decisions to be funded sufficiently, alongside environmental research, to enable adherence to core values of salience, legitimacy, credibility and transparency.
Inconsistent findings have been reported on the role of comorbid alcohol
use disorders as risk factors for a persistent course of depressive and
anxiety disorders.
Aims
To determine whether the course of depressive and/or anxiety disorders is
conditional on the type (abuse or dependence) or severity of comorbid
alcohol use disorders.
Method
In a large sample of participants with current depression and/or anxiety
(n = 1369) we examined whether the presence and
severity of DSM-IV alcohol abuse or alcohol dependence predicted the
2-year course of depressive and/or anxiety disorders.
Results
The persistence of depressive and/or anxiety disorders at the 2-year
follow-up was significantly higher in those with remitted or current
alcohol dependence (persistence 62% and 67% respectively), but not in
those with remitted or current alcohol abuse (persistence 51% and 46%
respectively), compared with no lifetime alcohol use disorder
(persistence 53%). Severe (meeting six or seven diagnostic criteria) but
not moderate (meeting three to five criteria) current dependence was a
significant predictor as 95% of those in the former group still had a
depressive and/or anxiety disorder at follow-up. This association
remained significant after adjustment for severity of depression and
anxiety, psychosocial factors and treatment factors.
Conclusions
Alcohol dependence, especially severe current dependence, is a risk
factor for an unfavourable course of depressive and/or anxiety disorders,
whereas alcohol abuse is not.
