Illicit Drug Use,Cognitive Distortions,and Suicidal Ideation Among Homeless Youth: Results From a Randomized Controlled Trial

Illicit drug use and cognitive distortions confer significant risks to youth suicidal thoughts and behaviors. However, there has been limited evidence regarding the efficacy of suicide prevention interventions with homeless youth, especially studies testing whether such interventions can reduce the risk for suicidal ideation associated with illicit drug use. Suicidal homeless youth (N = 150) between the ages of 18 to 24 years were recruited from a drop-in center. Youth were randomly assigned to Cognitive Therapy for Suicide Prevention (CTSP) + Treatment as Usual (TAU) or TAU alone. Youth reported their illicit drug use, cognitive distortions, and suicidal ideation 4 times over 9 months. A multiple-group multilevel structural equation model showed that higher illicit drug use at baseline predicted a slower reduction in cognitive distortions and suicidal ideation in the TAU group. These associations were not found in the CTSP + TAU group, suggesting an interruption of such risk from illicit drug use. Findings suggest that CTSP can reduce the risk of illicit drug use as a treatment barrier towards cognitive distortions and suicidal ideation among homeless youth, with implications to improve treatment efforts and to reduce premature mortality in a vulnerable population.

Validation and study of psychometric properties of a French version of the Highly Sensitive Person Scale (HSPS-FR)

IntroductionThe Highly Sensitive Person Scale based on the sensory-processing sensitivity is a self-assessment questionnaire consisting of 27 items. The scale is designed in order to identify individuals with high sensitivity.ObjectiveThe objective was to develop a French version of the scale. We tested its internal consistency and test-retest reliability on a French population sample. Another aim of this study was also to question the multidimensionality of the scale, for which several different models are suggested within the literature.MethodAfter translation and back-translation, a validation study was conducted on 814 adults. They were invited to complete an online questionnaire during the lockdown implemented due to COVID 19, between March 31st and May 11th (2020).ResultsThe internal reliability of the French version of HSPS was very good, with a Cronbach's alpha of .90, as was that of the factors. Correlations between factors were significant (p < .001). The intra-class correlation (ICC) for test-retest was .889 (0.874–0.903; 95% confidence interval). Factor analyses suggested a 4-factors structure, mixing the models found in the literature.ConclusionsThis study focused on a French adaptation of the HSPS scale. The results showed good psychometric qualities and stayed true to the original HSPS scale. The scale could be useful both to practitioners in their clinical practice and to researchers in fundamental research.     

中国情境下公共服务动机的理论构建与绩效转换机制

准确把握基层公职人员的公共服务动机是提升工作绩效、完善人力资源管理的重要前提。现有公共服务动机研究忽略了中国情景的特殊性, 对公共服务动机的微观激发机制及其消极绩效影响也关注不足。本研究从中国情景下公共服务动机的概念、核心构成要素、激发机制以及绩效结果入手, 从三个方面系统地构建适合中国场景的公共服务动机理论：第一, 将公共服务动机视为混合动机概念, 基于扎根理论的定性方式识别基层公务员公共服务动机的构成要素与核心内涵, 并据此开发本土化、多维度的公共服务动机量表; 第二, 从微观激发机制出发, 探讨受益人接触、自我倡议、观念反思等机制对个体公共服务动机的激发作用; 第三, 从积极影响和消极影响两个方面探讨公共服务动机与个体公务员行为间的关联及其机理。本研究既响应了国内公共管理学界长期以来发展本土理论的呼声, 亦为政府部门完善公共人事政策提供切实思路和实证依据。     

Assisted Suicide: Do We Own Our Bodies?

Abstract:  The ethics of physician‐assisted suicide is explored here in light of classic philosophical discussions of the ownership of one's body plus biblical discussions of the relationship of body and soul. Motives for individual and group suicide are brought to bear on bioethical principles such as that of autonomy. Ethical analysis is here challenged by the case of a 91 year‐old woman, Ragnhild, who lived after professional judgments that her life should be ended.     

Measure and integral with purely ordinal scales

We develop a purely ordinal model for aggregation functionals for lattice-valued functions, comprising as special cases quantiles, the Ky Fan metric and the Sugeno integral. For modelling findings of psychological experiments like the reflection effect in decision behaviour under risk or uncertainty, we introduce reflection lattices. These are complete linear lattices endowed with an order reversing bijection like the reflection at 0 on the real interval [−1,1]. Mathematically we investigate the lattice of nonvoid intervals in a complete linear lattice, then the class of monotone interval-valued functions and their inner product.

Stressful life events and suicidal behaviour in countries with different development levels: Nicaragua,El Salvador,Chile and Spain

This paper presents a study conducted on 709 Latin American undergraduates from four countries with different development levels (Nicaragua, El Salvador, Chile and Spain). The intention of this paper is to value the differences in the number and characteristics of stressful life events (SLE) suffered by the participants. Another purpose is to confirm the relation between SLE and suicidal conduct in Spanish cultural contexts, through the study of a multicultural sample of Spanish‐speaking university students, and finally, to isolate the SLE that allow predicting a later suicidal conduct to a greatest extent. The information was collected by means of a self‐applied questionnaire. The results indicate a greater presence of SLE among those who live in countries with lower development levels and among those who have attempted committing suicide. It is observed that the fact of having suffered certain SLE—physical or sexual mistreatment, excessive alcohol or drug consumption and having left home during childhood or adolescence—aid in the prediction of later suicidal conducts in the studied samples.

Perfectionism, anger, and anger rumination

Anger and anger rumination are considered to be detrimental to both physical and psychological well being. Furthermore, perfectionism, as a personality construct, seems to be related to various types of maladjustment. Whereas perfectionism has been characterized as being positive when an individual derives pleasure from striving for excellence yet recognizes and accepts individual limitations, it is deemed negative when the individual has unrealistic expectations and is never satisfied with his or her performance. The present study examined whether positive and negative perfectionism was associated with anger and anger rumination. The Farsi version of the Positive and Negative Perfectionism Scale and the Farsi version of the Anger Rumination Scale, as well as Spielberger's State-Trait Anger Scale were completed by 384 Iranian students. Results showed that anger and anger rumination were, as expected, associated negatively with positive perfectionism and associated positively with negative perfectionism. Positive perfectionism enables individuals to strive for success in a flexible manner and, thus, to experience satisfaction and pleasure rather than dissatisfaction, frustration, and anger. Conversely, negative perfectionism makes individuals vulnerable to emotional distress such as predisposition to experience anger and anger rumination through setting high standards for performance, overgeneralization of perceived failures, negative self-evaluation, self-blame, and measuring self-worth in terms of unachievable goals of accomplishment and productivity. Hence, perfectionism may be regarded as having both adaptive and maladaptive aspects with regard to health.     

Dynamics of choice: a tutorial

Choice may be defined as the allocation of behavior among activities. Since all activities take up time, choice is conveniently thought of as the allocation of time among activities, even if activities like pecking are most easily measured by counting. Since dynamics refers to change through time, the dynamics of choice refers to change of allocation through time. In the dynamics of choice, as in other dynamical systems that include feedback, change is away from perturbation and toward a steady state. Steady state or equilibrium is assessed on a longer time scale than change because change is only visible on a smaller time scale. When we compare laws of equilibrium, such as the matching law with laws of dynamics, two possibilities emerge. Self-similarity occurs when the same law can be seen across smaller time scales, with the result that the law at longer time scales may be understood as the expression of its application at smaller time scales. Reduction occurs when the dynamics at a small time scale are incommensurate with the dynamics at longer time scales. Then the process at the longer time scale is reduced to a qualitatively different process at the smaller time scale, as when choice is reduced to switching patterns. When reduction occurs, the dynamics at the longer time scale may be derived from the process at the smaller time scale, but not the other way around. Research at different time scales is facilitated by the molar view of behavior.
