Perfectionism, Negative Affect, Anxiety, and Self-evaluations for Brief Tasks

Perfectionism is a trait with multiple dimensions, which vary in terms of associated costs and benefits. Maladaptive perfectionism is related to neuroticism and involves self-criticism and perceptions of difficulty meeting high standards. In contrast, adaptive perfectionism is associated with conscientiousness and can be considered the healthy pursuit of high standards with minimal distress. Assessment of perfectionism has primarily been limited to self-report, so the present study investigated relationships between perfectionism dimensions and responses to a computerized search task in a sample of 133 undergraduates. In addition, friends and parents were asked to rate several traits of the participant using an online survey. The cost of errors for the task was manipulated, and maladaptive perfectionism subscales were hypothesized to predict worse performance and more task-related distress. Although neither maladaptive perfectionism nor adaptive perfectionism predicted task performance as hypothesized, maladaptive perfectionism predicted worse reactions: e.g., activated negative affect, frustration) to the task; however, incremental validity was limited. Unexpectedly, post-hoc analyses revealed that adaptive perfectionism predicted more frustration and less satisfaction for the task above and beyond conscientiousness. Informant ratings of participant personality traits demonstrated agreement, even for less observable measures, and achieved incremental validity beyond similar participant ratings in a few instances: e.g., task confidence). Informant ratings of personality seem to be useful supplements to self-report perfectionism measures. In addition, a brief task may not be suitable for observing the distinctive behavioral patterns of perfectionists. Although perfectionism dimensions overlap considerably with higher order personality constructs, they can provide unique information about meaningful outcomes. Recommendations for future research and implications are discussed

Interpersonal Constraint Conferred by Generalized Social Anxiety Disorder Is Evident on a Behavioral Economics Task

Although social anxiety disorder appears to confer impairment in friendships, evidence beyond selfreport is minimal. We used the flexible iterated prisoner’s dilemma as a simulated interaction with a friend with 27 individuals with the generalized type of social anxiety disorder and 23 demographically equivalent individuals without the disorder. Participants with generalized social anxiety disorder were less giving on the task. Lower giving was also moderately associated with interpersonal variables (e.g., coldness). A trend was also found for participants with generalized social anxiety disorder to show lower assertiveness on the task. The connection between generalized social anxiety disorder and friendship impairment appears likely to be partially explained by interpersonal constraint that is perceived by others as coldness and manifests in a behavioral economics task
