Introduction Previous research suggests that motivational factors relate to psychosocial functioning in SZ, both concurrently (Tobe et al. Compr Psychiat 2016; 65 103-109) and at follow-up (Fervaha et al. Acta Psychiat Scand 2014; 130 290-299). Importantly, no study has examined the influence of baseline motivation on the rate of change in response to rehabilitation Objectives 1. To study the relationship between baseline measures of motivation/ effort with psychosocial functioning at follow-up 2. To examine if motivation/ effort predict individual change in psychosocial functioning Methods Participants Table 1 summarizes the sample characteristics Results Figures 1 and 2 show individuals slopes for PSP and FAST, with a thick red line representing the average group slopes. For both PSP and FAST, models with only time as the independent variable and random intercepts indicated that time was a significant predictor ( PSP: t=10.65, p<.0001; FAST: t =-6.13, p<.0001). Baseline motivation/ effort → follow-up psychosocial functioning No significant correlations were found for neither PSP scores ( QLS: ρ=-.018, S=2343.3, p=.93, IMI: P=.23, t=1.09, p=.28, effort: ρ=.001, S=2297.3, p=.99) nor FAST scores ( QLS: ρ=-.16, S=2674.9, p=.45, IMI: P=-.02, t=-0.09, p=.92, effort: ρ=.07, S=2128, p=.72). Motivation → change in psychosocial functioning For PSP, the interaction model (Table 2) shows that the interaction of effort and timepoint significantly predicts PSP scores Variable Frequency Mean/ percentage Standard deviation Age 30 40.97 12.9 Gender 30 Male 19 63% Female 11 37% Years of Education 24 11.42 3.06 Diagnosis 30 … Schizophrenia 23 73% … Schizoaffective disorder 7 23% Figure 1.

Finally, unlike previous studies, basal motivation did not predict follow-up psychosocial functioning Disclosure of Interest None Declared
