After 6months of Switch, significant and important reduction in
motivational deficits (d=-0.98,p=.02)and functional outcomes
(d-0.90,p=.04).
After 12 months of Switch, significant and important reduction in
motivational deficits (d=-0.90,p=0.05). Moderate improvement
on functional outcomes, but statistically non-significant (d=0.42,
p=.30).
6months after the end of Switch, moderate reduction in
motivational deficits (d=-0.50,p=.23)and functional outcomes
(d=0.66,p=.17), but statistically non-significant.
Zero effect on reported quality of life.Secondary analyses:
improvement on satisfaction regarding family relationships.
ØModerate to moderately severe motivational negative
symptoms became light to moderate.Participants in Switch
showed more autonomy in their daily life after the intervention.
ØNeed to work on the maintenance of the improvement and the
impact on reported quality of life.
