(1>通过生态化识别获取用户回溯事件前的心理状态,实现对于事件影响的准确刻画。家庭暴力受害者的抑郁程度显著高于对照组(t =4.08, p<0.01 >,自杀可能性显著高于对照组(t=2.138 p<0.01>,生活满意度显著低于对照组用户(t =3.087, p<0.01,同时家庭暴力受害者的宜人性(t(1282)=7.071, p<0.01 >,尽责性较低(t(1282)=5.351, p<0.01>,神经质较高(t(1282)=-7.268, p<0.01>。该结果与以往研究结论相符。同时,由于生态化识别可以确认用户在经历事件前的心理状态,因此可以得出,受害者在家庭暴力后出现心理健康的消极变化,以及尽责性、神经质的变化;而受害者在受到家庭暴力前就己经展现出较低的宜人性及开放性。

(2)通过生态化识别方法测量失独用户的语言使用变化趋势,实现对失独用户的心理变化的纵向追踪。失独用户的心理健康状态略差于对照组用户,具体表现为使用更少的积极情绪词(t(452)=3.643, p<0.001,更多的消极情绪词尤其是悲伤词与死亡词(t(452)=3.643, p<0.001,该发现与以往研究结论相符。进一步,研究发现失独用户使用更多的家庭词(t(452)=3.643, p<0.001,且家庭词在失独后逐渐减少;失独用户的消极情绪词逐渐减少,而悲伤词维持不变(p>0.05 > ;失独用户在失独后短期内高频使用宗教词(t(166.053)=4.287, p<0.001,并在1年后恢复与对照组相同频率。



Other Abstract

The self-reporting method is the most widely used and most controversial measurement in psychological research. Although the self-reporting method is easy to operate and with high reliability and validity, it couldn't avoid the influence of the participants' motivation, the degree of cooperation, and the low reliability on retrospective research. This study proposes a new method of automatic recognizing psychological traits utilizing machine learning algorithm一Ecological Recognition (ER). ER refers to use ecological data and the machine learning algorithm to predict the psychological traits without contacting the participants. The new method can overcome the shortcomings of the traditional measurement methods, especially the studies of major life events. Through three horizontal researches, the current study verified the validity of ER on examining short-term effects, tracking the trajectory of the long-term impact, and identifying of psychological traits when self-report was not doable. Major life events like domestic violence, loss of the only child, and graduation and marriage of the novel protagonists were studied.

The results of the three studies are shown as follows:

(1)Study 1 examined the validity of ER by identifying the short-term effect of domestic violence. By measuring the psychological traits exactly before the event, we found a consistent conclusion with previous studies that the DV victims have higher level of depression and suicide probability, and a lower level of life satisfaction. The DV victims were lower scored in Agreeableness and Conscientiousness, while higher in Neuroticism. Further, as we measured the exact mental state before the event, it can be inferred that the victim had a poorer mental health after the domestic violence, as well as a decrease in Conscientiousness and an increase in Neuroticism afterwards.

(2) Study 2 examined the validity of ER by tracking the long-term trajectory of mental status after the loss of the only child. The mental status of the lost-only-child users were slightly worse than that of the control group, which is characterized by the use of fewer positive emotional words, and more negative emotional words, especially sad words and death words. Further, the study found that the lost-only-child users used more family words, and it gradually decrease after the loss; the use of negative emotional words gradually decrease, while the use of sad words remain unchanged; the lost-only-child users temporarily increased the frequency of using religious words and returned to normal after 1 year.

(3) Study 3 intended to test the validity of ER by identifying the character development of the protagonists in the "Ordinary World", Sun Shao'an and Sun Shaoping, whom cannot self-report for sure. Consistent with the novel scene, Shaoan has supreme extroversion, high conscientiousness and openness; Shaoping has high openness, conscientiousness and extroversion. Further, we examined the impact of graduation and marriage on personality development. Shaoan decreased in Agreeableness and increased in Neuroticism after got married; Shaoping got higher openness and lower Neuroticism after graduation, which is consistent with the conclusions of the similar life events in foreign studies.

The above three studies utilized several life events to prove the validity of the ER method. Compared with the traditional psychological measurement methods, the ER method can measure the psychological traits retrospectively and without contact, which is suitable for studies where the samples are hard to gain, the participants are not cooperated, and the mental status before the life events are difficult to backtrack. Combining with the traditional method, the ER method could effectively enlarge the application range and improve efficiency of the psychometry.
