Many recent studies have suggested that deficits in dietary-based omega-3 poly unsaturated fatty acids may make an etiological contribution to mood disorders and that supplementation with omega-3 poly unsaturated fatty acids may provide a treatment strategy (Hagg, 2003; Parker, Gibson, Brotchie, Rees, & Handzi-Pavlovic, 2006; Vaddadi, 2006). However, a few studies did examine the relationship between daily food intake and mood disorders. Thus, we surveyed students with regard to these relationships. Two hundred and forty eight university students completed the SDS and eighty item food appetite survey. Results showed that low-depression group tended to favor fish and deep yellow vegetables more than the high-depression group. These results suggest that a preference for fish and deep yellow vegetables relates to depression. Antioxidative effects of these foodstuffs may facilitate antidepressive effects of omega-3 poly unsaturated fatty acids.

The current study experimentally manipulated the process in which two types of products were provided: one had a characteristic design but its use was not readily apparent (the product requiring familiarization, or PRF) while the other had a general design and its use was readily apparent (the self-explanatory product, or SEP). The aim of this study was to investigate differences between the PRF and SEP in terms of the value of an emotional connection, the value of familiarization, and desire to buy. Results indicated that the PRF significantly induced both an emotional connection and familiarization more than the SEP did, but the desire to buy the two products did not differ significantly. The current results did not experimentally indicate whether an emotional connection or familiarization leads to a desire to buy. In addition, this study analyzed the association between formation of impressions of a PRF and the emotional connection or familiarization with that product. Results indicated that a more novel PRF resulted in a stronger emotional connection and increased familiarization. A bland impression diminished familiarization, but individual differences in a bland impression were not associated with an emotional connection. Impressions of the novelty of a PRF may be associated with encounters with that product overall while a bland impression may be specifically associated with certain encounters with that product.◆本研究では、デザインが特徴的で一見して使途がすぐにわからない商品(経験ブロバイダー商品)と、一般的なデザインで使途がすぐにわかる同じカテゴリの商品(対照商品)を呈示することで経験プロバイダーを実験的に操作し、これらの商品に対して、実験参加者の情緒的経験価値と関係的経験価値、および、購買意欲に違いが認められるのかを検証した。その結果、経験プロバイダー商品は対照商品よりも有意に情緒的経験価値と関係的経験価値を生じさせたが、それらの商品の購買意欲には違いが認められなかった。これらの結果から、経験価値が購買意欲の違いを生み出すかどうかを実験的に明らかにすることはできなかった。また、本研究で用いられた経験ブロバイダー商品の印象構造が情緒的経験価値と関係的経験価値とどのように関連するのかを検討した。その結果、これらの商品に対して斬新な印象を抱く人ほど、情緒的経験価値と関係的経験価値が高まり、柔和な印象を抱く人ほど関係的経験価値は低下するが、柔和な印象の個人差は情緒的経験価値と関連がないことが示された。これらの結果は、経験ブロバイダー商品に対する印象には、経験価値全般と関連するもの(斬新な印象)もある一方、経験価値と特異的に関連するもの(柔和な印象)もあることを示唆する。

Type D personality has recently attracted attention as a psychological factor closely related to the onset and progression of coronary heart disease (CHD). The purpose of the present research was to develop the Japanese version of Type D scale and to evaluate its validity and reliability. Participants (N=291; 133 CHD patients, 158 normal adults) completed questionnaires including the Japanese version of the Type D Scale (DS14), Hospital Anxiety and Depression Scale (HADS), Kikuchi's Social Skills Scale-18 (Kiss-18), and Negative Emotional Suppression Tendency Scale. Exploratory factor analysis of Japanese DS14 revealed two factors (social inhibition: SI, and negative affectivity: NA) comprised of 14 items. Confirmatory factor analysis indicated an adequate index of fitness. In addition, the scale had an acceptable internal consistency (Cronbach's alpha, SI=.862, and NA=.799), as well as adequate reliability. These results indicate that the Japanese version of DS14 is a clinically useful scale for evaluating Type D personality in patients with CHD.
