Resumo

GUNGOR, Buket et al. The comparison of risky and ambiguity decision making and cool executive functions between patients with obsessive compulsive disorder and healthy controls. Arch. Clin. Psychiatry (São Paulo) [online]. 2018, vol.45, n.5, pp.112-118. ISSN 1806-938X.  https://doi.org/10.1590/0101-60830000000170.

Background:

Executive functioning has been evaluated in obsessive compulsive disorder (OCD). Cool and hot executive functioning discrimination provided a different way of conceptualising executive functions.

Objectives:

The aim of this study was to compare ambiguity and risky decision-making and cool executive functions in an OCD and a healthy control group. The relationship between decision-making and cool executive functioning was investigated.

Methods:

Sixty-two OCD patients and 48 healthy control participants were compared. Decision-making was measured using the Iowa Gambling Task. The cool executive functioning was assessed using the Stroop Test and the Wisconsin Card Sorting Task (WCST).

Results:

The OCD group completed the WCST and the Stroop Test statistically significantly with a lower score than that of the control group. The OCD group had impaired response inhibition and set-shifting that indicate impaired cool executive functioning. In contrast to a lack of a statistically significant difference, the risky decision-making performance was worse in the OCD group than in the healthy control group and in the unmedicated OCD patients than in the medicated OCD patients.

Discussion:

The OCD patients had a poorer performance in risky decision-making and cool executive functioning. There was a link between risky decision-making performance and impaired cool executive functions.
