Diminished effort on a progressive ratio task in both unipolar and bipolar depression

Abstract: Background Amotivation, or decisional anhedonia, is a prominent and disabling feature of depression. However, this aspect of depression remains understudied, and no prior work has applied objective laboratory tests of motivation in both unipolar and bipolar depression. Methods We assessed motivation deficits using a Progressive Ratio Task (PRT) that indexes willingness to exert effort for monetary reward. The PRT was administered to 96 adults ages 18–60 including 25 participants with a current episode of uni… Show more

“…We recently demonstrated using task-based fMRI that depression severity is related to blunted VS responses to monetary rewards across unipolar and bipolar depression (6); others have reported similar results across a diverse group of patients with MDD, SCZ, alcohol dependence, ADHD and healthy controls (10). These findings highlight the value of dimensional approaches in identifying common neurobehavioral brain abnormalities (11). …”

“…A few other studies have used various non-learning tasks and have suggested that individuals with MDD have low motivation for monetary reward214142; however, in these studies, the focus was also on responses at the outcome phase2223. Unlike the abundant literature about responses to reward outcome (particularly during reward learning), little is known about whether individuals with MDD have intact ability to process and compare values during decision-making when no learning is required.…”

“…Within these patient samples, relationship between reported anhedonic symptoms and effortful performance has been mixed. Several studies have reported expected negative associations between effortful responses and anhedonic symptoms (Hershenberg et al, 2016;Treadway et al, 2012a;Yang et al, 2014), yet in several instances there was either no observed relationship (CleryMelin et al, 2011) or a an unexpected positive relationship between effort and total BDI scores (Treadway et al, 2012a), although further analysis suggests this might be driven by a positive association between self-criticism end effortful performance (Hershenberg et al, 2016). Of these studies, only one study to date has also examined effort-related behavior in patients diagnosed with bipolar disorder (currently depressed), and observed a near identical pattern when compared with unipolar patients (Hershenberg et al, 2016).…”

“…This includes behavioral measures of effort expenditure (Gold et al, 2013;Hartmann et al, 2015;Hershenberg et al, 2016;Treadway et al, 2009;Wolf et al, 2014), affective responses to positive stimuli (Bylsma et al, 2008;Dichter et al, 2010;Gold et al, 2008), and reinforcement learning (Pizzagalli et al, 2008) as well as self-report measures that seek to dissociate aspects of anticipation, motivation and enjoyment (eg, Cooper et al, 2008;Gard et al, 2006).…”
