Negative affectivity (NA) is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, and fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm. Individuals differ in negative emotional reactivity.〔Tellegen, A. (1985). Structures of mood and personality and their relevance to assessing anxiety, with an emphasis on self-report. In A. H. Tuma & J. D. Maser (Eds.), Anxiety and the Anxiety disorders, (pp. 681-706), Hilssdale, NJ: Erlbaum.〕 Trait negative affectivity roughly corresponds to the dominant personality factor of anxiety/neuroticism that is found within the Big Five personality traits as emotional stability. The Big Five are characterized as openness, conscientiousness, extraversion, agreeableness, and neuroticism. Neuroticism can plague an individual with severe mood swings, frequent sadness, worry, and also being easily disturbed.〔〔 Research shows that negative affectivity relates to different classes of variables: Self-reported stress and (poor) coping skills,〔 health complaints, and frequency of unpleasant events. Weight gain and mental health complaints are often experienced as well. People who express high negative affectivity view themselves and a variety of aspects of the world around them in generally negative terms.〔 Negative affectivity is strongly related to life satisfaction. Individuals high in negative affect will exhibit, on average, higher levels of distress, anxiety, and dissatisfaction, and tend to focus on the unpleasant aspects of themselves, the world, the future, and other people, and also evoke more negative life events. The similarities between these affective traits and life satisfaction have led some researchers to view both positive and negative affect with life satisfaction as specific indicators of the broader construct of subjective well-being. Negative affect arousal mechanisms can induce negative affective states as evidenced by a study conducted by Stanley S. Seidner on negative arousal and white noise. The study quantified reactions from Mexican and Puerto Rican participants in response to the devaluation of speakers from other ethnic origins.〔Seidner, Stanley S. (1991), Negative Affect Arousal Reactions from Mexican and Puerto Rican Respondents, Washington, D.C.: ERIC, ISBN ED346711 http://www.eric.ed.gov/ERICWebPortal/custom/portlets/recordDetails/detailmini.jsp?_nfpb=true&_&ERICExtSearch_SearchValue_0=ED346711&ERICExtSearch_SearchType_0=no&accno=ED346711〕 == Measurement == There are many instruments that can be used to measure negative affectivity, including measures of related concepts, such as neuroticism and trait anxiety. Two frequently used are: PANAS – The Positive and Negative Affect Schedule incorporates a 10-item negative affect scale. The PANAS-X is an expanded version of PANAS that incorporates negative affect subscales for Fear, Sadness, Guilt, Hostility, and Shyness. I-PANAS-SF - The International Positive and Negative Affect Schedule Short Form is an extensively validated brief, cross-culturally reliable 10-item version of the PANAS. Negative Affect items are Afraid, Ashamed, Hostile, Nervous and Upset. Internal consistency reliabilities between .72 and .76 are reported. The I-PANAS-SF was developed to eliminate redundant and ambiguous items and thereby derive an efficient measure for general use in research situations where either time or space are limited, or where international populations are of interest but where English may not be the mother tongue.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「negative affectivity」の詳細全文を読む スポンサード リンク
