Information security is a significant challenge for information and communication technologies (ICT). This includes withstanding attempts of social engineering aimed at manipulating people into divulging confidential information. However, many users are lacking awareness of the risks involved with, for example, password security. In a field survey that tested reciprocal behavior in social interactions, 1,208 participants were asked to reveal their personal password. More than one third of the participants shared their password with an unknown interviewer. In line with the social norm of reciprocity, people were more willing to do so when they received a small incentive (i.e., a piece of chocolate) before they were asked to reveal personal information. Elicitation was even more successful when the incentive was given right before asking for the password. The results, including moderating factors (e.g., age, gender), are discussed in the light of security awareness of ICT users and the mechanisms of psychological persuasion. [less ▲]

Workplace mobbing is a serious phenomenon that is costly to organizations and has various negative consequences of those targeted. The main purpose of the present study was to develop and validate a new short scale of workplace mobbing experience in three different language versions (German, French, Luxembourgish). Data were collected via computer-assisted telephone interviews in a sample of 1500 employees working in Luxembourg (aged from 17 to 64; 52.7 % male) that was representative of the commuter structure of Luxembourg’s workforce. Confirmatory factor analysis showed that the newly developed 5-item scale has good psychometric properties and partial scalar measurement invariance for the three different language versions. Internal consistency was satisfactory (α = .73). Correlations and hierarchical regression analysis with different working condition scales and psychological health scales confirm the construct validity of the new questionnaire. Although the present findings are preliminary in nature, they nevertheless support the reliability and validity of the scale and its use in psychological research. [less ▲]

Intuitive eating has been described to represent an adaptive eating behaviour that is characterised by eating in response to physiological hunger and satiety cues, rather than situational and emotional stimuli. The Intuitive Eating Scale-2 (IES-2) has been developed to measure such attitudes and behaviours on four subscales: unconditional permission to eat (UPE), eating for physical rather than emotional reasons (EPR), reliance on internal hunger and satiety cues (RHSC), and body-food choice congruence (B-FCC). The present study aimed at validating the psychometric properties of the German translation of the IES-2 in a large German-speaking sample. A second objective was to assess levels of intuitive eating in participants with an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, or binge eating disorder). The proposed factor structure of the IES-2 could be confirmed for the German translation of the questionnaire. The total score and most subscale scores were negatively related to eating disorder symptomatology, problems in appetite and emotional awareness, body dissatisfaction, and self-objectification. Women with eating disorders had significantly lower values on all IES-2 subscale scores and the total score than women without an eating disorder diagnosis. Women with a binge eating disorder (BED) diagnosis had higher scores on the UPE subscale compared to participants with anorexia nervosa (AN) or bulimia nervosa (BN), and those diagnosed with AN had higher scores on the EPR subscale than individuals with BN or BED. We conclude that the German IES-2 constitutes a useful self-report instrument for the assessment of intuitive eating in German-speaking samples. Further studies are warranted to evaluate psychometric properties of the IES-2 in different samples, and to investigate its application in a clinical setting. [less ▲]

Introduction and objective: A new instrument to measure quality of work was developed in three languages (German, French and Luxembourgish) and validated in a study of employees working in Luxembourg. Methods and results: A representative sample (n = 1529) was taken and exploratory factor analysis revealed a six-factor solution for the 21-item instrument (satisfaction and respect, mobbing, mental strain at work, cooperation, communication and feedback, and appraisal). Reliability analysis showed satisfying reliability for all six factors and the total questionnaire. In order to examine the construct validity of the new instrument, regression analyses were conducted to test whether the instrument predicted work characteristics’ influence on three components of well-being—burnout, psychological stress and maladaptive coping behaviors. Conclusion: The present validation offers a trilingual inventory for measuring quality of work that may be used, for example, as an assessment tool or for testing the effectiveness of interventions.

The high levels of violence in video games have often been linked to an apparent decrease in empathy and increase in selfishness in Western society, yet surprisingly little research has been conducted on the role of empathy in the context of media. Through three empirical studies, this book explores the mechanisms behind moderating functions of empathy. The chapters discuss factors such as character played and players' interpretation of the character, as well as the effects of inducing empathy before playing a video game upon emotion, cognition and behaviour. The book reveals new insights that will inform the ongoing debates about the effects of violent media content. [less ▲]
