This experiment examined six short texts for their effectiveness in inducing positive or negative mood in an online environment. Compared to two control groups, the texts successfully changed mood in the desired direction for mood measured on a single-item self-report scale. In accordance with previous research, negative mood was induced more effectively than positive mood. In addition to the self-report mood measure, two non-self-report mood measures are used; namely, word-pleasantness ratings and subjective probabilities of negative life-events. Pleasantness ratings of uncommon words seemed to be a suitable measure for mood, whereas subjective probabilities of negative life-events were not.

This study examines how occupational future time perspective (OFTP) affects organizational citizenship behaviour (OCB) and job satisfaction. OFTP reflects how much time and how many opportunities people perceive themselves as having left in their occupational future. OCB comprises extra-role behaviours that aim to support other individuals in the organization (OCBI) and the organization as a whole (OCBO). Socioemotional selectivity theory posits that people with an open-ended OFTP strive for knowledge-oriented goals (i.e. OCBO). In contrast, people with a constrained OFTP strive for emotion-oriented goals (i.e. OCBI). Thus, the more people perceive their OFTP as open-ended, the more they should show OCBO rather than OCBI. Applying a motivational OFTP approach to job satisfaction, the greater the open-ended people's OFTP, the more they should be satisfied with their job if they show more OCBO than OCBI because they can pursue their own goals. Findings support our hypotheses for people's perceived remaining opportunities in their occupational future. Herein, we discuss theoretical and practical implications of these findings.

Abstract

Trust has been found to be crucial for consumer behaviour towards online shops. However, existing studies on the role of trust in electronic commerce are mainly based on ad hoc scales to measure trustworthiness, merely rely on self‐reported consequences of trust such as intention to buy, and focus on low‐risk products.
In a web‐based study, 634 participants interacted with a provider of medical goods, that is a simulated online pharmacy. The study develops and employs a psychometrically sound scale for assessing perceived trustworthiness of online shops. Moreover, it examines the impact of trustworthiness on both consumers' intended and actual behaviour towards online shops.
Results show that trustworthiness promotes both intention to buy and actual financial risk taking. Perceived risk was not found to moderate the relationship between trustworthiness and intention to buy. Instead, trustworthiness partially mediated the influence of perceived risk on intention to buy. The results from the scale development challenge multidimensional conceptualizations of trust; comparing this finding with other studies suggests that the duration of the relationship might moderate the dimensionality of trust.

Introduction: Craving alcohol is a core symptom of alcohol use disorder (AUD) and an important target for treatment. A new line of treatment for AUD aims at overriding the urge to consume alcohol by changing implicit cognitions via approach bias modification (ApBM). In a prior study, we tested a variant of ApBM called imaginal retraining, which reduced craving. As addiction and body-focused repetitive behaviors (BFRBs) share important symptoms (e.g., inability to resist urges), for the present study we merged imaginal retraining with a technique aimed at BFRB, called decoupling, to augment treatment effects. We hypothesized that the new technique, which is called 3P, would lead to a greater reduction in craving relative to (active) control conditions. Methods: The study was conducted online. Data from 227 participants were considered. Participants were randomized to 1 out of 5 conditions. Craving for alcohol before and after the brief intervention was the primary outcome. Results: Only the 3P condition lessened craving by approximately one third at an almost medium effect size (improvement: 34.5%, p = 0.003, d = 0.458). Effects were significantly larger relative to the wait-list control and two active control conditions (p's < 0.02; greater reduction than imaginal retraining at a small but nonsignificant effect size). Discussion/Conclusion: If replicated, the combination of imaginal retraining and decoupling (3P) represents a promising, easy-to-implement self-help technique to reduce immediate craving. Long-term effects in participants with formally diagnosed AUD have not yet been investigated.

This study looks into the role that eye contact plays in helping people to control themselves in social settings and to avoid breaking social norms. Based on previous research, it is likely that eye contact increases prosocial behavior via heightened self-awareness and increased interpersonal synchrony. In our study, we propose that eye contact can also support constructive social behavior by causing people to experience heightened embarrassment when they are breaking social norms. We tested this in a lab experiment (N = 60) in which participants read insults at the experimenter (i.e., they exhibited norm breaking behavior). In the experimental condition, participants maintained eye contact with the experimenter. In the control condition, the experimenter did not maintain eye contact. We measured embarrassment with a self-report measure, heart rate to capture arousal, and two observational indicators of embarrassment (hesitation and laughter). In line with our hypotheses, having eye contact during norm breaking behavior as compared to no eye contact led to a stronger increase in self-reported embarrassment, a higher heart rate as well as more hesitation and more laughter. We conclude that eye contact does indeed lead to more embarrassment, while breaking social norms. This implies that eye contact gives people the power to punish norm breaking in others by inducing an aversive emotional experience.

<b><i>Introduction:</i></b> Imaginal retraining is a self-help technique that adapts the principles of approach bias modification to the imagination. Imaginal retraining has been shown to reduce craving and addictive behaviours in 3 randomized controlled trials (RCTs) on problematic alcohol consumption, overweight, and tobacco use. To date, there have been no studies evaluating the long-term efficacy of the intervention. The aim of the present study was to generate first hypotheses on the long-term efficacy of imaginal retraining in smokers in a controlled 1-year follow-up study. <b><i>Materials and Methods:</i></b> We recontacted the 345 participants who had taken part in an RCT on imaginal retraining for smokers 1 year later. The survey was carried out online and assessed craving for tobacco (primary outcome), smoking behaviour, well-being, and subjective appraisal. Individuals who applied the technique at least once during the previous year were categorized as the training group, whereas participants who never performed the training were categorized as the no-training group. Data were analysed using linear mixed models (LMMs). The study was preregistered as DRKS00021044. <b><i>Results:</i></b> The completion rate was 45.5%. Less than 40% used the intervention at least once in the previous 12 months. LMM analyses showed a significant reduction in craving for tobacco for the training compared to the no-training group after 1 year. No significant group differences emerged in smoking behaviour, depressive symptoms, or quality of life. Subjective appraisal of the intervention was favorable, similar to the initial study. <b><i>Conclusion:</i></b> The present study provides preliminary support for the long-term efficacy of imaginal retraining on craving for tobacco but not on smoking behaviour, highlighting the importance of multimodal treatment concepts in smoking cessation that target a variety of maintaining factors. Future studies need to investigate the long-term efficacy of the intervention in prospective RCTs that test alternative ways of conveying the technique to improve adherence.

Momentan besteht hohes wissenschaftspolitisches Interesse an der Entwicklung von Forschungsinfrastrukturen in allen Wissenschaftsbereichen. Wir plädieren dafür, ein national gefördertes Onlinelabor für die psychologische Forschung in diesen Diskurs einzubringen. Dieses Labor sollte einen großen Teilnehmerpool, notwendige Software-Tools, edukative Komponenten (Methodenberatung) sowie Schnittstellen zu Datenarchiven zur Verfügung stellen. Die Vorteile einer solchen Einrichtung werden auf der Basis von Effizienzbetrachtungen sowie methodischen und forschungsethischen Überlegungen verdeutlicht. Abschließend diskutieren wir mittelfristige Entwicklungspotenziale eines Nationalen Onlinelabors. ; There currently is a high level of science policy interest in the development of research infrastructures in all scientific areas. We propose to promote the idea of a national online laboratory within this discourse. This laboratory should provide access to a large participant pool, should offer software tools, provide education on Internet-based research methodologies, and should interface with data archives. We spell out the advantages of such a facility on the basis of efficiency concerns as well as considerations concerning research methodology and research ethics. We conclude with a discussion of mid-term developmental potentials of a nationally funded online laboratory.

Objectives: Medical residency is a challenging phase that puts the mental health of resident physicians at risk. This study explores the effects of a tailored mindfulness-based program on the positive mental health of resident physicians. Methods: We conducted a longitudinal randomized controlled trial with an active control group. The intervention group took part in an 8-week mindfulness-based program (MBP) that included a course book and was followed by a 4-month maintenance phase. The control group only received the course book for self-study. Participants were assessed at 0, 2, 6, and 12 months. Assessments included self-report measures (positive affect, life-satisfaction, self-compassion, flourishing, self-esteem, feeling loved, self-attributed mindfulness, time perception, "Muße" (i.e., feeling at ease and free of pressure), thriving at work, job satisfaction, self-efficacy, self-esteem), as well as Goal Attainment Scaling. Results: A total of 147 resident physicians were randomly assigned to either the intervention or the control group. In linear mixed models, we found small to medium effects for the interaction of time × group across various time points for self-compassion, flourishing, mindfulness, Muße, thriving at work, and indirect negative affect with effect sizes ranging between d = 0.25 and 0.88. Goal Attainment Scaling revealed a greater goal attainment in the intervention group compared to the control group (d = 1.50). Conclusions: We conclude that a tailored MBP may improve certain aspects of resident physicians' positive mental health. Trial Registration: DRKS00014015 05/24/2018.
