Chapter 2 52 Dropout and completion Measured from the point at which clients committed themselves to participation, dropout from IMR was 51%; measured from the moment of actual participation, it was 45%. The number of participants per IMR group at the start ranged from six to twelve, and the number in the last sessions from three to nine. Four groups were “closed groups” (no new influx at dropout); two groups had “rolling admissions”. Defined as > 70% participation, completion of IMR was 49%; measured from the moment of actual participation, it was 55%. If program completion is defined as having received all IMR modules (5), the completion rate was 44%; measured from the moment of actual participation, it was 49% (see Participant Flow, above, and Figure 1). Duration While the average length required per module lay between three and four 90minute sessions, it could vary between groups between one and eight sessions, according to the module and the group’s preference or specific challenges. The durations of the IMR training for the six groups were 8, 11, 12, 13, 15 and 17 months (M = 12.7 months, SD = 2.87). Completers’ characteristics at baseline Significantly more women than men completed IMR, and, at baseline, completers scored significantly better than non-completers on the client and clinician versions of the IMR scale. An association between completion and source of income showed that those in employment, those receiving unemployment benefit and those receiving invalidity benefit had a significantly greater chance of completing IMR than those receiving social security benefit. To us, this suggests that people who dropped out were at a greater distance from everyday working life, and possibly have more problems in maintaining structured and social activities than completers. There were no significant differences between completers and non-completers on the baseline scores of the Recovery Markers Questionnaire (RMQ) or the Global Assessment of Functioning scale (GAF). Neither were there associations between completion with living situation, education level, native country, diagnosis, period of start of problems, length of treatment, number of admissions, and length of hospitalization, see Table 1.
