Journal article (peer-reviewed)abstract
- A computerized paradigm was created to allow for testing in the laboratory whether increasing systematicity helps the recruiter make better selection decisions. Participants were introduced to the job and the applicants on the computer screen and asked to select who they thought should be considered for the job and who should not. Level of systematicity, i.e. the extent to which the recruitment is methodical and uses prepared tools, was manipulated between subjects. Depending on experimental condition participants were helped by means of a tool for extracting judgment criteria (job analysis) and a tool for making judgments related to selected criteria (including calculation of a final score). The general prediction that increased systematicity leads to the selection of more qualified candidates was supported by the results, particularly when the motivation to put time and effort into the task was higher. The results support the claim from Industrial/Organizational psychologists that systematicity is a desirable characteristic in selection processes. The fact that increasing systematicity led to better selection decisions in a controlled laboratory experiment, along with process-related measures, suggests that this kind of paradigm could be useful when evaluating new tools for improving selection decisions, before they are tested in large (and costly) field studies of actual personnel selection.

Is reliability compromised towards the end of long personality inventories?
- 2019
-
In: European Journal of Psychological Assessment. - : Hogrefe Publishing Group. - 2151-2426 .- 1015-5759. ; 35, s. 14-21

Journal article (peer-reviewed)abstract
- During very long self-rating sessions there is a risk that respondents will be tired and/or lose interest. Is this a concern for users of long personality inventories, such that the reliability becomes threatened in the latter half when respondents have made hundreds of personality self-ratings? Two thousand three hundred and fifty two volunteers completed long (≈ 500 items) personality inventories on the Internet, where items were presented in a unique random order for each participant. Perhaps counterintuitively, there was no evidence that reliability is threatened as respondents approach the end of a long personality inventory. If anything, the ratings in the second half of the inventories had higher reliability than ratings in the first half. Ratings were quicker towards the end of the inventories, but equally reliable. The criterion validity, estimated using Paunonen’s Behavior Report Form, was maintained too. The current results provide little reason to mistrust responses to items that appear towards the end of long personality inventories.

Is the general factor of personality based on evaluative responding? Experimental manipulation of item-popularity in personality inventories.
- 2016

In: Personality and Individual Differences. - : Elsevier BV. - 1873-3549 .- 0191-8869. ; 96, s. 31-35

Journal article (peer-reviewed)abstract
- The general factor of personality (GFP) is understood as a hierarchically superordinate factor, which suggests that it and the subordinate personality traits are mutually dependent on one another. If a personality inventory captures the subordinate traits the GFP should appear too. Likewise, manipulating the GFP should affect the subordinate traits and vice versa. The current study was an attempt to uniquely affect the size of the GFP by manipulating the evaluativeness of the inventory. First we estimated a general factor in a standard (evaluative) personality inventory, and found it to be robust. Then we estimated it in an inventory with evaluatively neutralized items, and found it to be unreliable. Finally, the neutralized inventory was made evaluative again. As expected, the GFP reappeared, suggesting the increased evaluative content to be the cause. Results are discussed in relation to personality assessment and to higher order factors in personality theory. It is suggested that for determining whether the GFP exists or not researchers should turn to other measures than personality inventories.

Self-control depletion impairs goal maintenance : A meta-analysis
- 2017
-
In: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564. ; 58:4, s. 284-293
-
Journal article (peer-reviewed)abstract
- Initial exertion of self-control has been suggested to impair subsequent self-regulatory performance. The specific cognitive processes that underlie this ego depletion effect have rarely been examined. Drawing on the dual-process theory of executive control (Engle & Kane, ; Kane & Engle, ), the current meta-analysis revealed that initial self-control exertion impairs participants' capacities of maintaining the task goal but its effect on capacities of resolving response competition is in need of further investigation. Our results are more consistent with recent theoretical views that consider ego depletion as a switch cost and a result arising from reduced motivation to engage in further self-control.

One-pot synthesis of cellulose-templated copper nanoparticles with antibacterial properties
- 2017
-
In: Materials letters (General ed.). - : Elsevier BV. - 0167-577X .- 1873-4979. ; 187, s. 170-172
-
Journal article (peer-reviewed)abstract
- We report a facile in situ synthesis of spherical copper nanoparticles (NPs) templated by a gelled cellulose II matrix under alkaline aqueous reaction conditions. In under 20 min, the hybrid material could be obtained in a one-pot reaction. Field-emission scanning electron microscopy (FE-SEM) revealed that the polycrystalline NPs of 200–500 nm were well distributed in the regenerated cellulose matrix. The average Cu crystallite size was of the order of 20 nm, as estimated from both X-ray diffraction (XRD) and FE-SEM. XRD data also indicated that the composite contained up to approximately 20% Cu2O. In suspensions containing the hybrid material, growth of Escerichia coli and Staphylococcus aureus strains was inhibited by 80% and 95%, respectively, after 72 h. The synthesis procedure offers a general approach to designing various low-cost hybrid materials of almost any shape, and the concept could be extended to utilization areas such as catalysis, functional textiles, and food packaging as well as to electronic applications.

Choice-justifications after allocating resources in helping dilemmas
- 2017

Journal article (peer-reviewed)abstract
- How do donors reason and justify their choices when faced with dilemmas in a charitable context? In two studies, Swedish students were confronted with helping dilemmas based on the identifiable victim effect, the proportion dominance effect and the ingroup effect. Each dilemma consisted of two comparable charity projects and participants were asked to choose one project over the other. They were then asked to provide justifications of their choice by stating the relative importance of different types of reasons. When faced with an identified victim dilemma, participants did not choose the project including an identified victim more often than the project framed statistically, but those who did emphasized emotional reasons (e.g., “Because I had more empathic feelings”), but not any other reasons, more than those choosing the statistical project. When faced with a Proportion dominance dilemma, participants more often chose the project with a high rescue proportion (e.g., you can save 100% out of 30) than the project with a low rescue proportion (e.g., you can save 4% out of 800), and those who did emphasized efficacy reasons (e.g., “Because my money can make a greater difference there”), but no other reasons, more than those favoring the low recue proportion project. Finally, when faced with an Ingroup dilemma, participants more often chose the project that could help ingroup-victims over the project that could help outgroup victims, and those who did emphasized responsibility reasons (e.g., “Because I have a greater obligation”), but no other reasons, more than those favoring outgroup projects. These results are consistent with and extend previous findings about how different helping effects are related to different psychological processes.

Emotional reactions, perceived impact and perceived responsibility mediate the identifiable victim effect, proportion dominance effect and in-group effect respectively
- 2015
-
In: Organizational Behavior and Human Decision Processes. - : Elsevier BV. - 0749-5978 .- 1095-9920. ; 127:March, s. 1-14
-
Journal article (peer-reviewed)abstract
- This study investigated possible mediators of the identifiable victim effect (IVE), the proportion dominance effect (PDE), and the in-group effect (IGE) in helping situations. In Studies 1-3, participants rated their emotional reactions (distress and sympathy toward the victims), perceived impact of helping, perceived responsibility to help, and helping motivation toward four versions of a helping situation. Gradually increasing victim identifiability in the helping situations primarily affected emotional reactions and sympathy completely mediated the IVE. Gradually making the reference-group smaller primarily affected perceived impact, and impact completely mediated the PDE. Gradually increasing in-groupness primarily affected perceived responsibility, and responsibility completely mediated the IGE. Study 4 included real monetary allocations and largely replicated the results using a between-subject design. Together, the results shed light on how contextual factors trigger help motivation, and indicate that different helping effects are primarily mediated by different mechanisms.

Judgments of warmth and competence in a computerized paradigm: Little evidence of proposed impression formation asymmetries
- 2017
-
In: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 12:4, s. 1-17
-
Journal article (peer-reviewed)abstract
- Much of what we know concerning impression formation is based on experimental methods where the participant receives a list of traits or behaviors and is asked to make trait judgments or meta-cognitive judgments. The present study aimed to put some well-known effects from the impression formation literature to a test in a more dynamic computerized environment, more akin to many real world impression formation scenarios. In three studies participants were introduced to multiple target persons. They were given information about the target persons’ behavior, one at a time, while making ratings of their warmth and competence, and their probability of performing related behaviors in the future. In neither of the studies the negativity effect of warmth or the positivity effect of competence were reproduced.

Adolescent and Family-Focused Cognitive-Behavioural Therapy for Paediatric Bipolar Disorders: A Case Series
- 2017
-
In: Clinical Psychology & Psychotherapy. - : Wiley. - 1099-0879 .- 1063-3995. ; 24:3, s. 589-617

Journal article (peer-reviewed)abstract
- Although pharmacological treatments can help alleviate mood symptoms in youth with paediatric bipolar disorder (PBD), residual symptoms still commonly persist. In many cases, these symptoms seriously affect the social and psychological development of children and adolescents suffering from PBD. Complementary interventions, such as psychosocial and psychoeducational treatments, can help children and their families manage mood regulation and other challenges throughout childhood and adolescence. However, most research on such interventions has focused on children, single-family psychoeducation, and individual cognitive behavioural therapy. The present study, conducted in Sweden, used a case-series design to explore whether child- and family-focused cognitive behavioural therapy (CFF-CBT) for PBD, adapted from children (8-12 years) to adolescents (13-18 years) and applied in a multi-family format, could help reduce symptoms, improve psychosocial functioning, increase parents' knowledge of and skills for coping with the disorder, and improve family expressed emotion for adolescents with PBD. Furthermore, we aimed to assess whether the effects of such CFF-CBT are maintained at a one-year follow-up. Seven adolescents and 11 parents in two multi-family groups received twelve sessions of CFF-CBT. Self-rating questionnaires and clinical observations were used to evaluate clinically significant changes for individual cases. The results suggest that CFF-CBT is feasible to deliver in an outpatient psychiatric setting and may be effective for developing parents' skills and knowledge for coping with PBD, increasing adolescents' psychosocial functioning, and improving family climate. The results are in line with previous findings on CFF-CBT for children with PBD, suggesting that CFF-CBT is a valuable adjunctive treatment for adolescents with PBD. Key Practitioner Message: Preliminary evidence indicates that CFF-CBT (RAINBOW) is both acceptable and an important complement to pharmacological treatment for adolescents suffering from paediatric bipolar disorder (PBD). Adolescent PBD populations show a high degree of comorbidity and individual clinical presentations that influence treatment results. Families show a large variation in ability to participate and benefit from RAINBOW treatment. Assessing and addressing pre-treatment environmental stressors and family climate during treatment is important for optimizing treatment effect. Symptoms of PBD fluctuate and new episodes can occur spontaneously. It is therefore important to follow PBD symptoms over time to draw more precise conclusions on treatment effects. When assessing treatment effects on psychiatric symptoms, social functioning, and family climate, it is important to use multiple rating sources, as ratings can vary considerably between adolescents, parents, and clinicians.
