Psychometric properties and measurement invariance of Depression,Anxiety and Stress Scales (DASS-21) across cultures

Cross-culturally measurement invariant instruments are useful for the assessment of mental symptoms across cultures. The current study aimed to investigate the psychometric properties and measurement invariance of the Depression, Anxiety and Stress Scales (DASS-21) (DASS) across Pakistan and Germany. German participants were recruited through an online survey (N = 1323), while Pakistani participants were recruited through online survey or paper-and-pencil survey (N = 1841). The DASS-21 showed good reliability, construct and structure validity in both countries. The DASS-21 indicated partial weak (stress subscale) and partial strong measurement invariance (depression and anxiety subscales) between both countries. Latent mean comparison of depression and anxiety symptoms between Pakistani and German students indicated that Pakistani university students experience more symptoms of depression and anxiety. Results suggest that the DASS-21 could be used in Pakistan and Germany, but caution should be taken when making direct comparisons between the two countries.     

The Bioterrorism Threat and Dual-use Biotechnological Research: An Israeli Perspective

Israel has a long history of concern with chemical and biological threats, since several hostile states in the Middle East are likely to possess such weapons. The Twin-Tower terrorist attacks and Anthrax envelope scares of 2001 were a watershed for public perceptions of the threat of unconventional terror in general and of biological terror in particular. New advances in biotechnology will only increase the ability of terrorists to exploit the burgeoning availability of related information to develop ever-more destructive bioweapons. Many areas of modern biological research are unavoidably dual-use by nature. They thus have a great potential for both help and harm; and facilitating the former while preventing the latter remains a serious challenge to researchers and governments alike. This article addresses how Israel might best (1) prevent hostile elements from obtaining, from Israel’s biological research system, materials, information and technologies that might facilitate their carrying out a biological attack, while (2) continuing to promote academic openness, excellence and other hallmarks of that system. This important and sensitive issue was assessed by a special national committee, and their recommendations are presented and discussed. One particularly innovative element is the restructuring and use of Israel’s extensive biosafety system to also address biosecurity goals, with minimal disruption or delay.     

Garner interference and temporal information processing

The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment.     

Consciousness and control in task switching

Participants were required to switch among randomly ordered tasks, and instructional cues were used to indicate which task to execute. In Experiments 1 and 2, the participants indicated their readiness for the task switch before they received the target stimulus; thus, each trial was associated with two primary dependent measures: (1) readiness time and (2) target reaction time. Slow readiness responses and instructions emphasizing high readiness were paradoxically accompanied by slow target reaction time. Moreover, the effect of task switching on readiness time was an order of magnitude smaller then the (objectively estimated) duration required for task preparation (Experiment 3). The results strongly suggest that participants have little conscious awareness of their preparedness and challenge commonly accepted assumptions concerning the role of consciousness in cognitive control.     

The self and the brand

Whereas [Oyserman, D. 2009. Identity-based motivation: Implications for action-readiness, procedural-readiness, and consumer behavior. Journal of Consumer Psychology. (this issue)] highlights the importance of identity motivation, this commentary suggests that the interesting questions for consumer researchers are not about identity per se, but about the relationship between the self and brand-related consumption. Two broad areas of investigation that can form an agenda for further research are proposed. The first area concerns the relationship among brands, identity and goals. The second area concerns the potential negative effects of identity on brand choice and on perceptions of identity-related behavior. Consumer researchers are best positioned to pursue issues dealing with the intersection of identity and brands, which can lead to both theoretical and substantive insights.     

Prevention of school bullying: The important role of autonomy‐supportive teaching and internalization of pro‐social values

Background. This study examined students’ perceptions of autonomy‐supportive teaching (AST) and its relations to internalization of pro‐social values and bullying in class. Aims. We hypothesized that: (1) teachers’ AST, which involves provision of rationale and taking the student's perspective, would relate positively to students’ identified internalization of considerateness towards classmates, and would relate negatively to external regulation (considerateness to obtain rewards or avoid punishments); (2) students’ identified regulation would relate negatively to self‐reported bullying in class, whereas external regulation would relate positively to bullying; and (3) the relation between teachers’ AST and student bullying would be mediated by students’ identification with the value of considerateness towards others. Sample. The sample consisted of 725 junior high school students (50% females) in Grades 7 and 8 from 27 classes in four schools serving students from lower‐middle to middle‐class socioeconomic backgrounds. Method. The participants completed questionnaires assessing the variables of interest. Results. Correlational analysis supported the hypotheses. Moreover, mediational analyses using hierarchical linear modelling (HLM) demonstrated that identified regulation mediates the negative relation between AST and self‐reported bullying in class. The mediational hypothesis was supported at the between‐class level and at the within‐class level. Conclusions. The findings suggest that school policy aimed at bullying reduction should go beyond external control that involves external rewards and sanctions and should help teachers acquire autonomy‐supportive practices focusing on students’ meaningful internalization.
