Abstract

Olfactory dysfunction can have a negative impact on emotional well-being. The aim of the present study was to examine associations between olfactory deficits and two affective personality characteristics (trait anxiety/trait depression).

A questionnaire study was conducted with a total of 116 participants (33 classified as anosmic, 40 as hyposmic, and 39 as normosmic). All participants gave self-reports on two facets of trait depression (dysthymia, euthymia) and trait anxiety (arousal, worrying). Due to the fact that in all three groups, trait depression and anxiety were substantially correlated, analyses of covariance were conducted.

After controlling for trait depression, anosmic and hyposmic patients showed lower trait arousal compared to normosmic controls (partial η ²?=?.05). After controlling for trait anxiety, patients scored higher on dysthymia (partial η ²?=?.06).

This study underlines the importance of statistically isolating specific associations between each of these affective personality characteristics and olfactory dysfunction.

The present findings suggest that olfactory dysfunction can have opposite effects on facets of trait depression and trait anxiety.

嗅觉功能障碍中的情感性人格特征:心境恶劣和觉醒的作用

嗅觉功能障碍会对情绪健康产生负面影响。本研究的目的是研究嗅觉缺陷与两种情感人格特征(特质焦虑/特质抑郁)之间的关系。对116名参与者进行问卷调查研究(33名被分类为嗅觉缺失，40名被分类为嗅觉缺失，39名被分类为正常)。所有参与者都对特质抑郁(心境恶劣、心境愉悦)和特质焦虑(兴奋、担忧)的两个方面进行了自我报告。由于在所有三组中，特质性抑郁与焦虑均存在显著相关，因此进行协方差分析。在控制特质抑郁后，嗅觉缺失和低嗅觉缺失患者的特质唤醒比正常对照组低(部分η 2?=? 0.05)。在控制特质焦虑后，患者在心境恶劣方面得分更高(部分η 2?=?.06)。这项研究强调了统计分离这些情感人格特征和嗅觉功能障碍之间特定关联的重要性。目前的研究结果表明，嗅觉功能障碍可能对特质抑郁和特质焦虑有相反的影响。
