Personality traits and coping compensate for disadvantageous decision-making in long-term alcohol abstinence.
OBJECTIVE
High relapse rate and extreme difficulty to maintain abstinence are core characteristics of alcohol dependence (AD). Previous studies have demonstrated a persistent decision-making (DM) deficit in AD. We aimed to reveal specific personality features and stress-coping mechanisms presumed to compensate for ineffective DM skills.


METHODS
Eighty-eight unmedicated patients with AD were enrolled. Intact general cognitive status was assured by IQ above 90. Forty-three patients had an average abstinence period of 12 weeks and were currently in an inpatient treatment program (short-term abstinence group, STA) and 45 patients were abstinent for at least 3 years (long-term abstinence group, LTA). The two groups were assessed using an integrative approach combining domains of DM, temperament and character dimensions and stress-coping measures.


RESULTS
Both groups performed at chance level with no linear improvement tendency on the gambling task assessing DM adequacy. The LTA group scored significantly higher on scales of self-directedness and cooperativeness. In contrast, levels of harm avoidance, emotion-oriented coping and perceived stress were significantly higher in the STA group.


CONCLUSIONS
Our findings provide new evidence for a persistent DM deficit with no learning effect in AD. Despite the deficit, alcohol-dependent patients can achieve LTA. STA patients perceive higher levels of stress and use non-adaptive coping strategies. We propose that the more adaptive personality profile of LTA patients contributes to the compensation of the trait-like DM deficit in alcoholism. These compensatory features represent promising new targets for preventive measures and therapeutic interventions in AD.
