社会经济不平等对个体生命史策略的影响——国家发展水平的调节作用

经济不平等不仅是经济问题,也会对个体心理行为产生诸多影响。前人认为,经济不平等会强化个体阶层提升意愿。结合生命史理论,研究提出高不平等将使个体偏好后代质量而非数量,以实现阶层提升,且这一现象在高发展水平国家中更为明显。基于开源数据,通过国家/个人两个水平上的分析发现,在高发展水平国家,经济不平等降低了国家生育率,并使个体更关切后代教育。研究结果可为理解特定经济环境下的个体心理和行为提供参考。     

Using baseline to diagnose internal states? Listen closely

Little is known about the mechanisms underlying how interviewers establish and monitor baselines of respondent behaviour. This study addresses this knowledge gap by characterising the practice of establishing baselines and measuring the accuracy of interviewer judgements based on assessments of baseline and departure behaviours. Eighteen professional interviewers viewed two videos of naturalistic interviews, reported the cues they perceived as informative for establishing and assessing a baseline, and diagnosed respondents' internal states. Participants reported multiple cue types as informative, but predominantly relied on non‐verbal cues. Overall, participants were sensitive to 27% of respondents' identified internal states but showed improvement over time. They achieved a hit rate of 20% during early interview stages and a hit rate of 33% during late stages. Although non‐verbal cues dominated reports, attending to verbal cues afforded participants greater efficiency in identifying respondent internal states. Implications and recommendations for practice are discussed.     

Childhood obesity and parental reflective functioning: Is there a relation?

Background/ObjectiveIn recent decades, the prevalence of childhood obesity has increased, with the major implications for public health. However, the factors that contribute to obesity in children are still poorly understood. The present study aimed to investigate the role of parental reflective functioning (PRF) in childhood obesity.MethodIn a cross-sectional design, 120 sets of parents of 60 children (n = 30 with obesity, age range 6–11) were recruited by local paediatricians. Parents completed the Parental Reflective Functioning Questionnaire. Children's and parents’ weight (assessed by BMI), as well as their socio-economic status (SES), were assessed to explore the contribution of PRF in the prediction of children's weight, controlling for parents’ weight and SES.Resultst-test showed significant differences with medium effect sizes in BMI, SES and PRF between parents of children with and without obesity. The best model resulted from hierarchical multiple regression analyses and showed that mothers’ PRF predicted children's BMI above and beyond the prediction by parents’ BMI and SES.ConclusionsLow maternal PRF could be an important target for intervention strategies, highlighting the need to consider parental responses to children's emotions in the treatment of childhood obesity, particularly in parents with low SES and high BMI.     

The relationship between childhood abuse and depression in a sample of Chinese people who use methamphetamine

Background/ObjectivePrevious studies have shown that childhood abuse is associated with symptoms of depression. This study aims to examine the prevalence of childhood abuse or neglect and its correlation with depression among a sample of Chinese people who use methamphetamine.MethodPeople who use methamphetamine (MA) (N = 1,173) were recruited from government-operated drug rehabilitation centres in Anhui province, China. Participants were assessed using the short form of Childhood Trauma Questionnaire and the Beck Depression Inventory-II for childhood abuse or neglect and depression symptoms.ResultsA total of 44.6% of people who use MA reported moderate/severe childhood abuse or neglect, and 56.9% of this sample were diagnosed with depression. Emotional abuse, sexual abuse, emotional neglect and physical neglect were revealed to increase the risk of depression. Multivariable regression analyses showed that depression scores were significantly predicted by gender, duration of drug use, sexual abuse and emotional neglect (model R² = .08, p < .001). The interaction between emotional neglect and duration of drug use on the depression was statistically significant.ConclusionsThese analyses indicate that sexual abuse and emotional neglect increase the severity of depression in individuals who use MA in drug rehabilitation centres of China.

Survey Satisficing Biases the Estimation of Moderation Effects

Survey satisficing in online data collection biases the estimation of treatment effects in many ways. Extending the findings of a previous study, which demonstrated that satisficing biased the estimation of main treatment effects, this study also shows that satisficing distorts the estimation of moderation effects. Targeting Japanese adults’ attitudes toward food, this study tests how the effect of country of production (Japan vs. China) is moderated by preexisting ethnocentric attitudes. The results show that while nonsatisficers predictably adjust their attitude toward food based on their preexisting ethnocentric attitude, satisficers stick to their initial stereotypical response. That is, the theoretically predicted moderation effect was observed among nonsatisficers, but not among satisficers, which indicates that satisficing biases not only the estimation of a treatment effect but also that of a moderation effect.     

Gene therapy: ethical issues

To discern the ethical issues involved incurrent gene therapy research, to explore theproblems inherent in possible future genetherapies, and to encourage debate within thescientific community about ethical questionsrelevant to both, we surveyed American Societyof Human Genetics scientists who engage inhuman genetics research. This study of theopinions of U.S. scientific experts about theethical issues discussed in the literature ongene therapy contributes systematic data on theattitudes of those working in the field as wellas elaborative comments. Our survey finds thatrespondents are highly supportive of thepotential use of somatic cell gene therapy tocure serious diseases in adults and children aswell as prospective offspring. A clearmajority, however, believe that using suchgenetic techniques for enhancement purposes isunacceptable. Delineating the line betweendisease/disorder and improvement/enhancementposes a problem not easily resolved and oneconducive to the growth of slippery-slopeapprehensions. The majority of respondents alsoadvocate germ-line therapy, in theory at least,and under similar restrictions, but theyrecognize the roadblock that the existence ofunanticipated negative consequences currentlypresents. Another complex matter involvestrying to determine appropriate reasons forchoosing target diseases for research, forwhich the dichotomy between rare single-geneand common multifactorial diseases reveals anongoing dilemma.     

问卷调查中被试不认真作答的控制与识别

问卷调查是心理与教育领域十分常见的数据收集方法, 而被试的不认真作答可能导致问卷数据失真。回顾已有研究发现:(a)不认真作答可以从外在作答模式和内在产生原因两个方向进行定义; (b)不认真作答的常见事前控制方法主要包括降低任务难度以及提高被试作答动机两大类; (c)事后识别方法主要包括嵌入识别量表、作答模式识别、反应时识别三大类。今后的研究中应基于作答机制的研究优化与开发控制方法, 检验作答识别方法的跨情境适用性并开发新方法, 并对局部不认真的识别与处理进行更深入的探讨。     

Do patients suffering from chronic diseases retrospectively overestimate how healthy they were before they fell ill?

Background/Objective: To examine the impact of a disease on a person's subjective health state, patients are often asked to assess their current health state and to retrospectively assess how healthy they were before they fell ill. The objective of this study was to test whether patients generally overestimated the quality of their pre-disease health. Method: Six samples of patients with chronic diseases (cancer patients, cardiovascular patients, and patients diagnosed with sarcoidosis, N between 197 and 1,197) were analyzed. The patients assessed their current health states and their health states at the time before diagnosis. The retrospective scores were compared with matched data from general population studies. Results: In three of the six studies, the retrospective health ratings of the patients were significantly higher than the general population norms (effect sizes between 0.24 and 0.46), two studies yielded nonsignificant effects, and in one study there was an opposite trend. The general overestimation of pre-disease health was more pronounced in older patients as compared with younger ones, and it was more pronounced when global health/quality of life was to be assessed. Conclusions: Retrospective assessments of pre-disease health states are not appropriate for assessing disease-related changes in a person's health state.
