Does motivation and effort predict improvement on psychosocial functioning in schizophrenia (SZ)?

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
