Chapter 3: Positive Thinking: what are the common<br />

psychiatric characteristics <strong>of</strong> paintings?<br />

Chapter 3 summarises the review to identify the central importance <strong>of</strong> developing<br />

systematic, content-free assessments <strong>of</strong> psychiatric patients' paintings.<br />

Firstly the findings from the literature review showed the kinds <strong>of</strong> measurement<br />

which had been employed and had the best repeatability for a suitable test. <strong>The</strong>se<br />

selected papers will now be subjected to a further analysis designed to make some sense<br />

<strong>of</strong> their contradictions and put them on an equal footing, so as to find out what kind <strong>of</strong><br />

effects to expect. <strong>The</strong>n, the development <strong>of</strong> a novel instrument (the DAPA) for such<br />

assessments is presented.<br />

Meta Analysis <strong>of</strong> reliable studies identified by the literature review<br />

Analysis <strong>of</strong> tabulated categories and variables from the empirical literature was performed<br />

in 2 ways:<br />

1. <strong>The</strong> reliability and the validity <strong>of</strong> this classification system was qualitatively<br />

assessed in Chapter 2, by discussion and comparison between all studies on<br />

similar variables. This process <strong>of</strong> simplifying and displaying common themes<br />

was exploratory.<br />

2. A meta analysis was performed on studies that conformed to the minimum<br />

scientific criteria for <strong>quantitative</strong> work to complement the discursive assessment.<br />
