Mindfulness And Physical Activity As Moderators Of Behavioral Inhibition Sensitivity And Psychological Distress, Edward Silber
Mindfulness And Physical Activity As Moderators Of Behavioral Inhibition Sensitivity And Psychological Distress, Edward Silber
LSU Master's Theses
Framed in Reinforcement Sensitivity Theory, the current study examined the moderating effects of mindfulness and moderate-to-vigorous physical activity (MVPA) on the relationship between behavioral inhibition system (BIS) sensitivity and psychological distress. Participants (N=183) were college students at a large public university in the Southeastern United States. Data were collected using an online survey with self-report questionnaires that demonstrated acceptable reliability. Data analysis utilized multiple linear regression models to test study hypotheses. Findings revealed a significant positive relationship between BIS sensitivity and psychological distress, with mindfulness and MVPA significantly moderating this association. Specifically, increased reports of mindfulness and MVPA …

Motivation deficits (i.e., avolition or amotivation) are a cardinal feature of schizophrenia spectrum disorders (SSDs) and are linked to worse functional outcomes. Accumulating evidence implicates underactive dopamine responses in reward areas of the brain (e.g., striatum) in the etiology of amotivation. Phasic dopamine firing in the striatum purportedly has a role in increasing the perceived value of a potential reward that, in effect, helps “push” the organism toward initiating and persisting in the action to pursue rewards. Previous research has suggested that eye blink rate (EBR) may be a reliable and valid index of striatal dopamine. Amotivation (clinician-rated and self-reported) …
