BACKGROUND: Alienation is derived from dissimilation in philosophy. It is practically defined as the subjective state of individuals who develop negative feelings such as social isolation, uncontrollable and meaningless sense, oppression, and self-alienation because they are alien to others, the society, nature and themselves, and even feel controlled.OBJECTIVE: To investigate alienation from psychological perspective, aiming to construct and verify the theoretical hypothesis of alienation, thereby working out...

BACKGROUND: Alienation is derived from dissimilation in philosophy. It is practically defined as the subjective state of individuals who develop negative feelings such as social isolation, uncontrollable and meaningless sense, oppression, and self-alienation because they are alien to others, the society, nature and themselves, and even feel controlled.OBJECTIVE: To investigate alienation from psychological perspective, aiming to construct and verify the theoretical hypothesis of alienation, thereby working out alienation scale for adolescent students. DESIGN:Cross-sectional investigation.SETTING:National Key Research Center of Basic Psychology and National Key Liberal Arts of Southwest Normal University. PARTICIPANTS: The investigation was carried out from March to June 2000. The method of cohort stratified random sampling was adopted and the questionnaire was administered to adolescent students in Chongqing City and Lanzhou City. Inclusion criteria: volunteer students of grade one in junior high school to grade four in colleges. Exclusion criteria: Those who had incomplete data or had differences of more than 6 points in the total scores for three matched lie-testing questions in the questionnaire. A total of 1502 pieces of questionnaire were collected (including 1 066 questionnaires used for exploratory factor analysis and 436 questionnaires for verifying factor analysis); the age of the students covered the whole range of adolescence, and the boy-to-girl ratio in each grade was matched. METHODS:We combined literature analysis, investigation research and interview. The details are as follows: First, theoretical hypothesis was put forward based on literature analysis; then related variances were collected through interviews and open questionnaires, which were compared with the items in scales used home and abroad at present so as to work out predicting questions for adolescence alienation questionnaire. Finally, 52 items were screened out and used to construct the preliminary questionnaire. The formal alienation scale was made after standardized designation of behavioral variances, and verified for alienation analysis in adolescent students. MAIN OUTCOME MEASURES: Behavioral apparent variances were collected based on interviews and open questionnaires, and used as psychological potential variances after statistical processing. RESULTS: Data of 1502 pieces of questionnaire were analyzed. ① The correlation coefficient of each item in the scale was over 0.35. ② The correlation coefficient of each item with the dimension was over 0.30, with statistical significance (P < 0.01). ③ The reliability coefficient of each item was over 0.39 with great significance (P < 0.01). ④ Alienation was displayed in three dimensions: social alienation, interpersonal alienation and surrounding alienation, which were associated with the corresponding dimensions of related scales (P < 0.05-0.01). ⑤Alienation could be divided into 9 levels: sense of meaninglessness, sense of self alienation, isolation, nature alienation, parent alienation, environmental alienation, sense of uncontrollability and social alienation. Parameters that accorded with the theoretical hypothesis and used for verifying analysis were proved rational. Based on the analysis of the 9 first-rank factors, second-rank structural model of 3 unrelated factors were obtained using main component analysis and the maximum variance cross rotation with the optimal coefficients of simulated parameters of: X2/df=4.87;GFI=0.94;AGFI=0.90;RMR=0.05;NFI=0.93;NNFI=0.92;CFI=0.95;IFI=0.95. CONCLUSION: Alienation scale has been proved to be reliable and valid. It can be used to assess alienation in adolescent students and has potential value of application in healthy psychological development and psychological education.

背景:疏离来自于哲学中的异化。疏离感的操作性定义为个体与周围的人、社会、自然以及自己等各种关系网络之间,由于正常的关系发生疏远,甚至被支配、控制,从而使个体产生了社会孤立感、不可控制感、无意义感、压迫拘束感、自我疏离感等消极的情感。目的:从心理学的角度对疏离感进行探讨,构建疏离感的理论并对理论假设进行验证,编制青少年学生疏离感测量量表。设计:横断面调查。单位:西南师范大学全国重点学科“基础心理学研究中心”和西南师范大学全国重点文科研究基地“西南民族教育与心理研究中心”。对象:本调查于2000-03/06进行,采用整群分层随机抽样的方法,选取重庆市和甘肃省兰州市的青少年学生进行集体施测。纳入标准:自愿参加测试的初一到大学四年级的学生。排除标准:所填写问卷中3对测谎题配对总分数相差超过6分及有缺失数据者。共收回有效问卷1502份(包括探索性因素分析所用问卷1066份和验证性因素分析所用问卷436份),学生年龄构成基本覆盖了整个青少年期。每个年级男女生比率基本相同。方法:文献分析法、调查研究法和个别访谈法相结合。具体程序为:先通过文献分析法构建理论假设,再通过访谈和开放式问卷搜集行为变量,同时参照国内外有关量表的项...
