行为安全“2-4”模型的扩充版

现有的行为安全\"2-4\"模型已能够精确定位事故\"管理漏洞\"原因的具体位置和内容,但由于未考虑事故发生内、外部组织因素的影响,因此尚不能全面揭示事故发生的原因。以行为安全\"2-4\"模型为基础,提出了包含几类影响因素在内的扩充版行为安全\"2-4\"模型,并应用该模型对国家标准给出的事故原因进行了重新归类,将事故责任者进行了科学定义与分类,同时基于该模型得到了事故预防线路图。研究得到的扩充版行为安全\"2-4\"模型增加了\"内部影响链\"和\"外部影响链\",这两条链中的动作发出者会通过确定的路线来影响事故的发生;应用该模型将国家标准给出的12种事故原因归为直接、间接、根本、内部影响以及外部影响原因;按照事故的责任与原因相对应原则,将事故责任者分为直接、间接、主要、内部影响以及外部影响责任者5类;将该模型中的事故、损失等不安全方面分别改为安全业绩、收益等安全方面后得到了事故预防图,可为事故预防提供借鉴。

Development of a shortened center for epidemiological studies depression scale for assessment of depression in rheumatoid arthritis.

Objective: The purpose was to develop a short-form version of the Center for Epidemiologic Studies Depression Scale (CES-D) for the identification of persons with major depressive disorder (MDD) within a population with rheumatoid arthritis (RA). Study Design: Data were analyzed from 337 persons with RA. Forty-six participants met the diagnostic criteria for MDD; 291 participants were classified in the non-MDD category (including 21 participants with dysthymia and 18 participants with minor depressive disorder). A short-form version of the CES-D was developed, and multiple cutoff scores were examined. Results: A cutoff score of ≥5 from a 9-item, short-form CES-D was found to be generally as efficient as the more commonly used full-scale cutoff score of ≥16 for classifying participants with MDD within an RA population. Although the shortened CES-D scale (cutoff score ≥5) was slightly more sensitive, it also exhibited slightly less specificity than the full-scale cutoff score of ≥16. Conclusion: The results suggest that a short-form CES-D can be used to screen for MDD within an RA sample with a degree of efficiency that is generally comparable to that of the full-scale instrument.

Further Validity Evidence for the Teacher Version of the Child Symptom lnventory-4.

The reliability and validity of the teacher version of the Child Symptom Inventory-4 (CSI-4) was examined in 248 boys referred for evaluation of behavioral and emotional problems. The CSI-4 is a behavior rating scale whose items correspond to the symptoms of DSM-IV-defined disorders. The results indicated satisfactory internal consistency reliabilities for most symptom categories, and CSI-4 scores converged and diverged in a theoretically consistent manner with respective scales of the Teacher's Report Form (Achenbach, 1991), the IOWA Conners Teacher's Rating Scale (Loney & Milich, 1982), and the Diagnostic Interview for Children and Adolescents-Revised Parent Version (DICA-P; Reich, Shayka, & Taibleson, 1991). Correlations between teacher and parent CSI-4 ratings were low to moderate, whereas all correlations between teacher ratings and child self report were very low (rs     

La mesure de perfectionnisme: Validation canadienne-fran?aise du Positive and Negative Perfectionism Scale.

The purpose of this study was to verify the validity of a French version of the Positive and Negative Perfectionism Scale developed by L. A. Terry-Short (1995). This instrument measures the type as well as the level of perfectionism in adolescents. The instrument was first administered to 734 7th, 9th, and 11th grade students. Four weeks later, 596 Ss were invited to answer the questionnaire once more. The factorial structure, temporal stability and internal consistency of each subscales of the translated version of the instrument correspond to those of the original version.

Validation chez les adolescents d'une version francophone d'un instrument de mesure de la peur du jugement négatif d'autrui.

The popularity of the Fear of Negative Evaluation scale (FNE; Watson & Friend, 1969) stems from the centrality of this construct in personality, social and clinical psychology. In order to meet the needs of the Francophone researchers community, Kéroack, Boisvert, and Prévost (1987) traduced the short version of this instrument. Since social anxiety is most salient in adolescence, there is a need for normative and psychometric data for this population. This research aims at documenting the psychometric properties and norms for Francophone adolescents. Five hundred and seventy-eight participants aged from 14 to 19 years completed the French versions of the short FNE and the Social Avoidance and Distress scale. The factorial structure, the internal consistency and the convergent validity analyses confirm the traduction's quality and the questionnaire's validity. Norms are presented separately for females and males. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Screening for posttraumatic stress disorder: An evaluation of two self-report scales among crime victims.

The validity of the Impact of Events Scale (IES) and the Posttraumatic Stress Disorder (PTSD) Symptom Scale, Self-Report version (PSS-SR) was examined among crime victims. Both instruments performed well as screeners for PTSD. For the IES, sensitivity ranged between .93 and 1.00; for the PSS-SR, sensitivity ranged between .80 and .90. Specificity for the IES ranged between .78 and .84 and for the PSS-SR ranged between .84 and .88. Some individual items from the 2 scales performed just as well as the total scales. The authors conclude that either of these short self-report instruments or their individual items are suitable as screeners for PTSD, specifically in settings where mental health professionals are unavailable. Cross-validation of these results is necessary because of the small sample size in this study. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
