Attrition and grouping of persons in different phases of the study with people with ID, MID, BIF and LP.

Figure 2
People with BIF gave open answers to four questions about ‘things that bring joy and satisfaction’ (n = 117; 267 answers); ‘the most successful things in life’ (n = 102; 149 answers); ‘things that have failed’ (n = 86; 87 answers); and ‘things that are difficult’ (n = 92; 112 answers). This figure shows the five most commonly answered categories for each question.
