DOI: 10.1002/gps.4818
Abstract: Motivational deficits are prevalent in patients with schizophrenia, persist despite antipsychotic treatment, and predict long‐term outcomes. Evidence suggests that patients with greater amotivation have smaller ventral striatum (VS) volumes. We wished to replicate this finding… read more here.

DOI: 10.1007/s00406-018-0918-y
Abstract: Amotivation is a major determinant of functional outcome in schizophrenia but it is understudied in the early course of illness. There is a paucity of longitudinal research investigating predictors of amotivation. In this study, we… read more here.

Effort-based decision-making impairment in patients with clinically-stabilized first-episode psychosis and its relationship with amotivation and psychosocial functioning
Sign Up to like & getrecommendations! Published in 2019 at "European Neuropsychopharmacology"
DOI: 10.1016/j.euroneuro.2019.03.006
Abstract: Effort-based decision-making has recently been proposed as a potential mechanism contributing to motivational deficits (amotivation) in psychotic disorder. Previous research has identified altered effort allocation in chronic schizophrenia, but produced mixed results regarding its relationship… read more here.

Abnormal cognitive effort allocation and its association with amotivation in first-episode psychosis
Sign Up to like & getrecommendations! Published in 2019 at "Psychological Medicine"
DOI: 10.1017/s0033291719002769
Abstract: Abstract Background Abnormal effort-based decision-making represents a potential mechanism underlying motivational deficits (amotivation) in psychotic disorders. Previous research identified effort allocation impairment in chronic schizophrenia and focused mostly on physical effort modality. No study has… read more here.

DOI: 10.1037/abn0000509
Abstract: Impaired cognition and amotivation are considered core features of psychotic disorders. Amotivation may manifest as reduced willingness to expend effort on cognitive tasks. It remains unclear whether reduced effort is responsible for any of the… read more here.

DOI: 10.1093/schbul/sbaa031.137
Abstract: Abstract Background Negative symptoms of schizophrenia are suggested to map onto two distinct factors – amotivation and diminished expression, which relate to different aspects of behaviour and neural activity. Most research in patients with schizophrenia… read more here.

DOI: 10.3389/fpsyt.2023.1123046
Abstract: Introduction Suboptimal effort-based decision-making with reduced willingness to expend effort for high-probability/high-value reward is observed in schizophrenia patients and is related to diminished motivation, but is understudied in schizotypy. This study aimed to examine effort-allocation… read more here.
