Fluid intelligence is defined as the ability to deal with new information. Contrary to crystallized intelligence, fluid intelligence is particularly vulnerable to decline associated with aging (Horn, 1985; Smits, Smit, Van den Heuvel, & Jonker, 1997). Fluid intelligence is assessed with the Raven Coloured Progressive Matrices (RCPM, Raven, 1995). The RCPM is a non-verbal visual test, assessing the ability for non-verbal and abstract reasoning. The original version of the RCPM consists of three sections, A, Ab, and B. Each subset contains 12 items, and each item consists of a drawing (matrix) of a pattern from which a section is missing. On the bottom of the page six patterns are printed, one of which fits in the missing section. The respondent has to choose which of the six alternatives fits best. Each correctly chosen pattern counts for one point, resulting in a total scale score ranging from 0 to 24. The items increase in difficulty, and so do the three sections. Previous studies show a strong correlation between test performance and level of education (Smits et al, 1997), intellectual and visual spatial capacities (Raven, 1984), and dementia (Gainotti, Parlato, Monteleone & Carlomagno, 1992).
Measurement instrument in LASA
In LASA, only subset A and B from the RAVEN are used, due to time limitations. This adaptation hardly affects the interpretation of the test performance, as pilot studies showed a very strong correlation between the sumscore of A, Ab and B and the sumscore of A and B ((r = 0.96) Deeg & Smit, 1993). If the response on one of the first three items of subset A is wrong, the interviewer gives feedback, until the object of the task is absolutely clear. At the baseline measurement, by means of three additional questions the respondents are asked to evaluate their performance on this test.
The total score on the RCPB consists of the sum of correct answers in sections A and B. Both sections consist of 12 items, resulting in a possible score range of 0-12 per section and 0-24 for the total score. If one or two items in a section are missing, these items are assumed to be 0. If more than two items in a section are missing, neither the score for that section nor the total score is computed.

(RAVEN ©, scoring protocol);
LASAB024 (main interview, in English / in Dutch)
The LASA022 files contain the scores on the individual items; the variable names for subset A are *RAVA1 for the first item to *RAVA12 for the last item; the variable names for subset B are *RAVB1 for the first item to *RAVB12 for the last item. The LASA222 files contain the sumscores. LASAB024 contains the scores on the evaluation of the Raven by the respondents (MECOG1, MECOG2, MECOG3).

Previous use in LASA
RCPM is often used as one of the indicators of verbal or fluid intelligence in studies on cognitive ageing (Aartsen et al., 2004; Zimprich et al., 2004), or as predictor of change in other domains of functioning (Aartsen et al, 2002; Van Schoor et al., 2002). It has also been investigated as dependent variable (Robitaille et al., 2013; Aartsen et al., 1998; Aartsen et al., 2002; Dik et al., 2003), or as a factor that was associated with other domains of functioning (Comijs et al., 2001).
