The K10 focuses on anxiety and depression. It has been validated for use in population surveys<br />

rather than primary care.<br />

‡<br />

Adapt for other substance misuse.<br />

#<br />

Validated using a pragmatic composite gold standard to check for tobacco use, alcohol and<br />

other drug misuse, problem gambling, and anger problems. Less reliable for exercise and eating<br />

5.4 Assessment tools: evidence review<br />

A systematic review of the evidence on brief assessment tools for common mental<br />

disorders in adults/pakeke was undertaken. ‘Brief’ was defined as taking 5 minutes<br />

or less to administer.<br />

The relevant evidence comprised 4 systematic reviews 65,176,310,311 and 27 primary studies<br />

(some of which were included in the systematic reviews), which evaluated a total of<br />

18 different assessment tools. Tools for which evidence of effectiveness was found are<br />

discussed below. For several tools there was insufficient evidence of validity in a primary<br />

care setting: details of other studies and tools evaluated can be found in evidence table<br />

4d on the <strong>New</strong> <strong>Zealand</strong> Guidelines Group (NZGG) website (http://www.nzgg.org.nz –<br />

enter ‘evidence tables’ into search box, then select publication by title).<br />
