Abstract

本研究は,社交不安障害の維持要因であるコストバイアスと,抑うつ症状と関連する不合理な信念を取り上げ,双方の認知が社会不安と関連する程度の違いについて検討することが目的であった.調査の回答に同意の得られた大学生201名を対象に質問紙調査を行った.分析の結果,コストバイアスと不合理な信念は,ともに社会不安・抑うつ症状と中程度の正の相関関係が認められた.また,不合理な信念の影響を制御した際の偏相関係数は,コストバイアスと社会不安の関係が強いことを示した.一方,コストバイアスを制御した際の偏相関係数から,不合理な信念と社会不安の関係の弱まることが示唆された.すなわち,社会不安においては,社会的状況に特化した認知が強く関係することが認められた.以上から,SAD症状の改善には,コストバイアスを低減させる認知療法などのアプローチが有効であると示唆された.

Social Anxiety Disorder (SAD) is known as the most common type of Anxiety Disorder. In recent studies, it was suggested the cost and probability bias is considered to be a maintaining factor of SAD symptoms. Especially, previous research revealed that the reduction of cost bias was highly related to the improvement of SAD symptoms. In SAD, previous studies also suggested that depressive symptoms often occur secondarily. It was also reported that depressed patients held irrational belief and it could lead to their negative mood. However, the difference of correlationship among cost bias, irrational belief, and SAD symptoms has not been understood in detail. In this study, the purpose was to examine the difference of correlationship among cost bias, irrational belief, and social anxiety. Undergraduate students (n=201) completed a set of questionnaires : the Social Cost/Probability scale (SCOP) ; the Short Fear of Negative Evaluation scale (SFNE) ; the Liebowitz Social Anxiety Scale (LSAS); the Japanese Irrational Belief Test (JIBT) ; and the Self-Rated Depression Scale(SDS). First, correlation analysis revealed that there was a moderate positive correlationship among each measure. Second, partial correlation coefficients among each measure by controlling JIBT were calculated. The results indicated that cost bias related to social anxiety independently. Third, partial correlation coefficients between each measure by controlling SCOP indicated that there was a weak relationship between irrational belief and social anxiety. These results indicated that cost bias which is the specific cognitive bias in social anxiety is strongly rerated to SAD symptoms. On the other hand, it was a suggested that there was a spurious correlation between irrational belief and social anxiety. Based on these findings, the importance to assess and improve the specific cognitive bias in SAD was indicated.
