Introduction: Atopic dermatitis (AD) is closely related to health related quality of life (HRQOL). The present study examined how "anxiety to itch" affects HRQOL by examing adult AD patients and healthy undergraduate students by using path analysis. Method: The participants were 42 adult AD patients (AD group: 15 male, 27 female; Mean age=29.12; SD=9.27) and 164 healthy undergraduate students (student group: 63 male, 101 female; Mean age=20.83; SD=3.57). "Anxiety to itch" was measured by using the Itch Anxiety Scale for Atopic Dermatitis (IAS-AD) that the author had made (Himachi et al., 2005). The reliability and validity of IAS-AD are confirmed. Scratching was measured by using a scratching checklist in daily life, and HRQOL was measured by using the Mos 36-Items Short-Form Health Survey (SF-36). Results: Each score of the scales was compared between the AD group and the student group by t test. The result revealed that the AD group showed significantly higher scores than the student group in the IAS-AD (t[55]=-11.89, p<0.001) and the scratching checklist (t[45]=-6.14, p<0.001). In addition, the general health (GH) score of SF-36 also showed that the AD group had significantly lower scores than the student group (t[204]=2.34, p<0.05). Because validity of the hypothesized model was demonstrated, analysis was conducted to test a difference between clinical and non-clinical groups in the structural parameters of the model, using the multiple-group procedure. Result of the multiple-group procedure indicated that the model procedure was a good fit (GFI: 0.96, AGFI: 0.89, CFI: 0.98, RMSEA: 0.046). The result of the present study revealed that IAS-AD contributed more strongly to scratching (path coefficient: 0.74, p<0.001) in the AD group than the student group. The influence of scratching on the score of bodily pain (BP), social functioning (SF), and mental health (MH) in AD group (BP: -0.40, SF: -0.41, MH: -0.41, p<0.01) was greater than that of in the student group (BP: -0.27, SF: -0.23, MH: -0.23, p<0.01). Conclusion: It is concluded that the AD patients significantly showed higher scores than healthy undergraduate students in "anxiety to itch" and scratching. Furthermore, it became clear that adult AD patients' scratching has more negative effect on mental aspects, such as SF and MH, compared with healthy students. It is necessary to examine the effect of the treatment which includes intervention in "anxiety to itch" for adult AD patients.

大学生のヘルスプロモーションを目的とした集団ストレスマネジメント教育がストレス反応の低減に及ぼす効果を検討した。大学１年生を対象に，ストレスのメカニズムについて理解を促した後，複数のリラクセーション技法（呼吸法，漸進的筋弛緩法，イメージ）を紹介し，その習得訓練を行った。時期を要因とする一要因分散分析の結果，実施1ヵ月後の心理的ストレス反応が実施前よりも減少する傾向にあった。しかし，訓練を完遂した学生とドロップアウトした学生の間でストレス反応に有意な差は認められなかった。かった。また，脈拍において有意な変化は認められなかった。

大学生を対象に，小児・児童期の家庭での食事環境において「雰囲気が良い」と認知した条件を明らかにし，食事場面における雰囲気の良さが親との心理的結合に及ぼす影響を検討した。母子結合性を従属変数，雰囲気の良さを規定する諸条件を独立変数とした重回帰分析を行った結果，母親との“仲の良さ”が最も大きな説明力を有し，母親側の“受け入れやすさ“が有する説明力は有意傾向であった。食事場面において，子どもが母親に対して安心感を持てる雰囲気を積極的に作ることが母子間の心理的結合性を強めることが示唆された。

成人型アトピー性皮膚炎患者の“痒みに対する不安”を測定するItch Anxiety Scale for Atopic Dermatitis (IAS-AD)を開発し，その信頼性と妥当性を検証した。探索的因子分析の結果，2因子17項目が抽出され，各因子の内的整合性は高かった。また，IAS-ADはSTAIと異なる不安を測定でき，かつアトピー性皮膚炎罹患の有無を予測することも可能であることが示された。

Objective : Atopic dermatitis (AD) is a chronic skin disorder. AD often develops between infancy and adolescence, runs a course of remissions and exacerbations. Originally, AD is child's skin disease. However, the number of AD patients is increasing. Adult AD patients generally show a high anxiety level. It is indicated that anxiety in adult patients causes high rate of scratching behavior. However, not much research on the anxiety to itch has been conducted enough in adult AD patients. The purpose of this study is to develop the Itch Anxiety Scale for Atopic Dermatitis (IAS-AD) to assess the anxiety to itch in adult AD patients. Method : The participants of this study were 294 undergraduate students. Forty-four undergraduate students were diagnosed as atopic dermatitis. The participant of this study completed the IAS-AD, the State-Trait Anxiety Inventory-form JYZ (STAI-JYZ), and the level of subjective itch by using Visual Analogue Scale (VAS). Results : Result of exploratory factor analysis revealed that the IAS-AD consisted of 17-items loading on two factors, which were named "Environmentally-induced type" and "Stress-induced type". Internal consistency of each factor was sufficiently high (α = 0.88-0.91). Result of t test revealed that undergraduate students with atopic dermatitis showed higher scores than healthy students in IAS-AD. In addition, a result of logistic regression analysis revealed that the IAS-AD predicted the morbidity of AD. Furthermore, for setting the cut-off point, ROC curve (Receiver operating characteristic curve) was calculated. Result of ROC analysis indicated that sensitivity and specificity were at their maximum when IAS-AD score was 37.5point. Therefore, the point of 37 was adopted as the cut-off point. Conclusion : It was concluded that the IAS-AD have high internal consistency and validity. It was suggested that the IAS-AD have potential significance for the clinical and research application. Finally, discussion was made on about IAS-AD with respect to severity of symptoms.
