Biased interpretation in perfectionistic concerns: an experimental investigation

Area of Science:

• Psychology
• Cognitive Science
• Clinical Psychology

Background:

• Perfectionism is linked to various psychological disorders.
• Understanding the cognitive processes, specifically biased information processing, is crucial for addressing perfectionism.
• The Frost Multidimensional Perfectionism Scale (FMPS) identifies different facets of perfectionism, including concern over mistakes.

Purpose of the Study:

• To investigate the relationship between heightened concern over mistakes in perfectionism and interpretation bias.
• To test the hypothesis that individuals with high concern over mistakes tend to interpret perfectionism-relevant situations negatively.

Main Methods:

• A quasi-experimental, within-subjects design was employed with 76 non-clinical participants.
• Participants rated the likelihood of positive and negative test sentences being implications of scenarios depicting protagonists falling short of their own high standards.
• A generalized linear mixed model was used for data analysis.

Main Results:

• Higher scores on the concern over mistakes subscale were significantly associated with a greater tendency to interpret scenarios negatively.
• Conversely, higher concern over mistakes scores correlated with a reduced tendency to interpret scenarios positively.
• This indicates a clear interpretation bias favoring negative outcomes in individuals with high concern over mistakes.

Conclusions:

• The study's findings support the cognitive-behavioral model of perfectionism.
• The results suggest that interpretation bias is a key cognitive process in perfectionism.
• Cognitive-behavioral therapy (CBT) for perfectionism should consider incorporating strategies to reduce interpretation bias.
