Dumpen och 2forty2 är grupper som ägnar sig åt att bedriva en digital pedofiljakt och att exponera förövare på sina digitala plattformar. Syftet med denna studie var att undersöka hur Dumpen och 2forty2 på sina hemsidor och Instagram-konton dels presenterar sig själva, dels på vilka grunder man berättigar sitt agerande. Genom en kvalitativ innehållsanalys av datamaterial från Dumpens hemsida och 2forty2´s Instagram-konto har syftet undersökts. Fynden från innehållsanalysen har sedan presenterats och jämförts med tidigare forskning och för studien aktuella kriminologiska teorier. I resultaten går att urskönja hur grupperna uppkommit utifrån en misstro till rättsväsendet, omvärldens uppmärksamhet och egna upplevelser av sexuella övergrepp. Avslutningsvis presenteras en bild kring hur grupperna verkar, presenterar sig och bakomliggande orsaker, samt förslag på framtida forskning kring dessa typer av grupper.

Problem Based Learning (PBL) has been fully or partly adopted by several medical and dental schools throughout the world, but only few attempts have been made to adjust this method to Distance Learning (DL) environments. It appears that the interaction demands of PBL could not be easily facilitated by the technologies used for DL in the past. The recent introduction of Virtual Learning Environments or Virtual Classrooms, is suggested by many as the development that could allow Distance Learning to utilise highly structured collaborative learning methods such as PBL. A literature review and two pilot studies were undertaken, in an attempt to investigate the possibility of adjusting an existing in-classroom PBL model to Internet-based environments for distance learning. There is a strong need of a conceptual theoretical framework and research results to support the function and effectiveness of distance learning in health education. Drop-out rates are still high in all kinds of distance education. Accreditation, team-work and personal contact, appear to be factors of importance for increasing motivation and minimising drop-out rates in distance learning. During the pilot studies it was evident that both postgraduate and undergraduate students were very positive towards the PBL method, as they experienced it while working over the network. However, it is very difficult to introduce inexperienced students to PBL through distance. Students? competence with computers seems to be an important factor for the success of a virtual classroom and their computer literacy has to be objectively assessed prior to any course. Significant differences were identified between in-classroom and over the Internet communication. These differences, although measured in the quantity of interaction, appear to influence the quality and depth of discussion as well. Tutor involvement was higher in the Internet discussions than the in-classroom ones. It was concluded that an entirely Internet-based PBL course is possible, if properly organised. However, such a model might constitute a compromise over the quality standards of in-classroom PBL, at least with the currently available Internet technology. A hybrid approach, which will combine personal contact with network-based interaction, might be the safest and most beneficial option right now. / <p>Note: The papers are not included in the fulltext online.</p>

The purpose of this research was to investigate the effect that mode of test administration could have on computerised assessment results involving proctored and unproctored test conditions. Two South African test instruments, the Learning Potential Computerised Adaptive Test (LPCAT) and the Career Preference Computerised Adaptive Test (CPCAT) were used in the study. A quantitative, quasi-experimental design was used, and a convenience sample for LPCAT (N=82) and CPCAT (N=81) consisted of employees in the hospitality industry. Using a within-participants design, the dependent t-test was used for statistical analysis. For the total group the LPCAT results yielded no statistically significant differences between the mean scores for the two different modes of administration. For the total group the CPCAT results yielded statistically significant differences in the mean scores per mode of administration for five out of 34 dimensions, however, for the majority of the CPCAT sub-dimensions, the mode of administration did not impact on results. It was concluded that mode of administration did not impact on the cognitive test scores and only to a very limited degree on the non-cognitive test scores. Based on the results the null hypotheses for the effect of mode of administration were not rejected. / Industrial & Organisational Psychology / M.A. (Industrial and Organisational Psychology)

Fear is an innate emotion and an adaptive response to provide protection from potential harm. When fear is excessive and out of proportion in relation to the confronted situation, it can lead to the development of an anxiety disorder. Many individuals feel anxious at some point, but not all experience clinical anxiety or meet the diagnostic criteria of an anxiety disorder. Still, anxiety disorders are the most prevalent form of psychiatric disorder in the general population. More often than not people suffering from one anxiety disorder also present other psychiatric conditions. As of today, cognitive and behavioural treatments have been tested and found to positively affect anxiety disorders, making them the treatment of choice. Nevertheless, many patients do not seek or receive adequate treatment. One common critique of the research trials from which the recommendations for treatments stem is the use of a single protocol targeting only one diagnosis. This is because many people suffer from comorbidities. Another problem connected to the recommendation that cognitive behavioural therapy (CBT) should be the treatment of choice for anxiety disorders is the lack of therapists with adequate training. One possible way of dealing both with the shortcoming of therapists and making CBT more accessible is the use of the Internet. Internet-based CBT (ICBT) has been tested in numerous trials during the last 15 years, showing positive outcomes for a large variety of disorders. Many ICBT trials also make use of a single protocol. Another way of dealing with comorbidities might be to tailor the treatment to let characteristics and preferences of the patient guide the design of the protocol. Little is known about possible effects of tailoring the ICBT, the effects of therapeutic relationships in ICBT, and the effectiveness and cost-effectiveness of these treatments. This thesis is based on three studies on two separate randomized controlled trials (RCTs) using the same set of modules accessible for the tailored protocol. Study I was an RCT investigating treatment effects up to two-year after completion, showing favourable outcomes of the treatment in a self-recruited sample at all measure points. Study II was a secondary analysis exploring possible relations between working alliance and treatment outcome for participants in the treatment group recruited for Study I indicating that working alliance predict outcome in this tailored treatment. The second RCT was an effectiveness trial (Study III) analysing treatment effects and cost-effectiveness of the treatment up to one year post treatment in a primary-care population. This study showed positive treatment effects both regarding symptom reduction and cost-effectiveness, and that effects were sustained at one year post treatment. Conclusions drawn from these studies are that individually tailored ICBT seems to be a feasible approach for patients with anxiety disorders regardless of comorbidities, and a responsible choice in terms of societal costs. / Rädsla är en medfödd känsla och en adaptiv respons för att skydda organismen från potentiell skada. När rädslan blir överdriven och oproportionerlig i relation till den konfronterade situationen, kan det leda till utvecklandet av ångestsyndrom. Många personer upplever någon gång ångest, men inte alla upplever klinisk ångest eller uppfyller de diagnostiska kriterierna för något ångestsyndrom. Trots detta är ångest det vanligaste psykiatriska tillståndet i befolkningen i stort och oftast uppfyller personer som lider av ett ångestsyndrom även andra  psykiatriska tillstånd. Till dags dato har både kognitiva och beteendeinriktade behandlingar testats och visat sig verksamma vid ångestproblem, vilket gjort dem till de behandlingar som rekommenderas för dessa tillstånd. Trots god effekt av behandling söker många patienter ändå inte hjälp, alternativt erhåller inte adekvat behandling. En vanlig kritik mot den forskning från vilka behandlingsrekommendationerna för ångestsyndrom stammar är att många använt en manual eller ett protokoll som riktar sig mot bara en diagnos. Detta på grund av den stora komorbiditeten. Ett annat problem kopplat till rekommendationerna att kognitiv beteendeterapi (KBT) ska vara förstahandsval vid behandling av ångest är bristen på behandlare med adekvat utbildning. Ett möjligt sätt att göra KBT mer tillgängligt är att använda Internet. Internet- förmedlad KBT (IKBT) har prövats i ett stort antal studier de senaste 15 åren dessa har visat positiva resultat vid ett stort antal psykiatriska tillstånd. Flertalet av dessa studier har dock använt ett enda behandlingsprotokoll. En annan möjlighet att hantera komorbiditet kan vara att skräddarsy behandlingen för att låta patientens egenskaper och preferenser vara med och styra utformningen av behandlingsprotokollet. Möjliga effekter av att skräddarsy IKBT är relativt lite undersökt, likaså effekterna av terapeutiska relationer i IKBT samt klinisk effektivitet och kostnadseffektiviteten för dessa behandlingar. Denna avhandling bygger på tre studier från två randomiserade kontrollerade studier med samma uppsättning av moduler tillgängliga för att skräddarsy behandlingsprotokollen. I Studie I undersöktes behandlingseffekter upp till två år efter avslutad behandling i en självrekryterad grupp patienter. Studie II var en sekundäranalys av behandlingsgruppen från Studie I där eventuella samband mellan arbetsallians och behandlingsresultat undersöktes. Den andra randomiserade kontrollerade studien var en prövning av huruvida denna behandling var effektiv för en klinisk population (Studie III) rekryterad via primärvården. Förutom behandlingseffekter undersöktes även kostnadseffektiviteten upp till ett år efter behandlingsavslut. De slutsatser som dras utifrån dessa studier är att skräddarsydd IKBT verkar vara en framkomlig väg för patienter med ångest oavsett komorbiditet, att arbetsalliansen kan vara en faktor som påverkar utfallet, samt att det är ett ansvarsfullt val vad gäller samhälleliga kostnader.

Sömnsvårigheter inklusive insomni är ett utbrett problem för stora delar av befolkningen. Personer med insomni tenderar att oroa sig över sin sömn och har dysfunktionella antaganden kring sömnbristens konsekvenser. Studiens huvudsakliga syfte var att undersöka om skillnader i utfall mellan två behandlingsmetoder för insomni kunde tillräknas en exponeringseffekt. Studiens hypoteser var: 1a) Patienter som deltar i sömnrestriktion kommer få en större reducering av oro över sin sömn. 1b) Det finns ett samband mellan hög följsamhet till behandlingsmetoden och minskad oro över sömnen. 2) En kraftigare exponering medför lägre följsamhet till behandlingsmetoden. 3) Det finns ett samband mellan minskad oro över sömnen och minskade insomnisymptom. Data användes där 185 deltagare randomiserats till någon av KBT-behandlingarna för insomni sömnkomprimering (n=93) och sömnrestriktion (n=92). Oron hade minskat för studiedeltagarna fem veckor efter behandlingsstart men inga signifikanta skillnader påträffades mellan grupperna. Ett signifikant samband observerades mellan minskning av insomnisymptom och oro över sömnbrist. Slutsatser från uppsatsen är det redan etablerade sambandet mellan oro och insomni bekräftas. Studien kunde inte bekräfta hypotesen att exponering leder till minskad oro. Vidare forskning rekommenderas för att avgöra hur exponering kan användas för patienter med insomni för att möjliggöra effektivare behandlingsmetoder. / Sleep impairments including insomnia is a widespread problem affecting a large quantity of the population. Insomnia patients tend to worry about their sleep and having dysfunctional beliefs about sleep deficit consequences. The main purpose of this study was to examine if differences in results between two treatment methods could be attributed to effects of exposure. The hypotheses in the study were: 1a) Patients who participate in sleep restriction will have a greater reduction of sleep-related worry. 1b) There is a correlation between high compliance to the treatment methods and reduced sleep-related worry. 2) A greater exposure induces lower compliance to the treatment methods. 3a) There is a correlation between reduction of sleep-related worry and reduction of insomnia symptoms. Data consisted of 185 participants who was randomised into the CBT-treatments for insomnia sleep compression (n=93) or sleep restriction (n=92). A hypothesis was that sleep restriction implicate more exposure than sleep compression. Worry had decreased among participants after five weeks of treatment but no significant differences occurred between the groups. A significant correlation occurred between reduction of insomnia symptoms and reduction of worries regarding sleep deficit. Conclusions is that the already established correlation between worry and insomnia is confirmed. This study failed to confirm that exposure leads to reduced worry. Further research is advised to determine how exposure can be used for insomnia patients to enable more efficient treatment methods. / ClinicalTrials.gov Identifier: NCT02743338, CompRest - a Comparison Between Sleep Compression and Sleep Restriction for Treating Insomnia

Estratégias de comunicação para transmitir mensagens que expressam tanto as perdas associadas ao hábito de fumar quanto os ganhos obtidos ao parar de fumar têm sido usadas para reduzir o consumo de tabaco. Entretanto, poucos estudos têm avaliado o efeito de tais mensagens elaboradas para a cessação tabágica e ainda não existem conclusões claras sobre qual tipo de mensagem é mais eficaz para motivar as pessoas a parar de fumar. Objetivo: O estudo avaliou qual tipo de mensagem relacionada ao tabagismo (positiva ou negativa) foi mais eficaz para o recrutamento online de fumantes através do Facebook Advertising. Métodos: Anúncios contendo aspectos negativos do tabagismo e aspectos positivos da cessação foram criados e divulgados pelo Facebook Ads. Ao clicar nos anúncios, os usuários eram automaticamente direcionados para a intervenção “Viva sem Tabaco” (www.vivasemtabaco.com.br). O valor gasto na divulgação foi de 647,64 reais. Os dados foram extraídos da plataforma de anúncios do Facebook e dos logs de acesso do servidor. Os dados de logs foram tratados e analisados usando a linguagem de programação R. Resultados: O anúncio positivo atingiu 174.029 pessoas e o negativo atingiu 180.527 pessoas, que foram convertidos em 2.688 e 3.662 cliques, respectivamente. O custo do clique foi de R$0,12 para o anúncio positivo e de R$0,09 para o anúncio negativo. Conclusões: O anúncio negativo alcançou maior número de usuários, gerou mais cliques para o site e teve maior conversão em número de contas e plano de parada criados. Anúncios contendo aspectos negativos do tabagismo parecem ser mais custo efetivo para o recrutamento e engajamento de fumantes à intervenção. Além disso, o Facebook mostrou ser uma boa ferramenta de divulgação e recrutamento e pode ser uma solução para a dificuldade de alcançar fumantes para intervenções de cessação. / Introduction: Gain and loss-framed messages about smoking have been used to promote cessation. However, there are still no clear conclusions about what kind of message is more effective to motivate smokers to quit. This study compared the effectiveness of loss and gainframed messages on smokers’ online recruitment through Facebook Advertising. Methods: Loss and gain-framed messages about smoking were created and released by Facebook Ads. The users who clicked on the ads were automatically redirected to the "Live Without Tobacco" intervention (www.vivasemtabaco.com.br). The amount spent on disclosure was 647.64 Brazilian reals. Data were collected from Facebook Ads platform and from a relational database. Analyses were performed on the 6.350 users who clicked on one of the ads and on 1.731 that were redirected to the intervention. Results: Gain-framed ads reached 174,029 people and loss-framed ads reached 180,527, which were converted into 2.688 and 3,662 clicks, respectively. The cost of the click was R$0.12 for gain-famed ads and R$0.09 for the loss-framed. Conclusion: Loss-framed ads reached more users, got more clicks on the website, and had a greater conversion to the number of accounts and quit plans created. Loss-framed messages about smoking appear to be more cost effective for both recruitment and engagement of smokers to the intervention. Facebook has proven to be a good outreach and recruitment tool and can be a solution to the difficulty of reaching smokers for cessation interventions.

Introduction The prevalence of depressive symptoms in persons with heart failure is higher than in age- and gender-matched populations not suffering from heart failure. Heart failure in itself is associated with an unpredictable trajectory of symptoms, a poor prognosis, high mortality and morbidity, and low health-related quality of life (HrQoL). With the addition of depressive symptoms to heart failure the negative health effects increase further. Though the negative consequences of depressive symptoms in heart failure are well known, there is a knowledge gap about the course of depressive symptoms in heart failure and about how to effectively manage these symptoms. Pharmacological treatment with serotonin reuptake inhibitors has not been able to demonstrate efficacy in persons with heart failure. In a few studies, cognitive behavioural therapy (CBT) delivered face-to-face, has demonstrated effects on depressive symptoms in persons with heart failure. However, currently there are barriers in delivering face-to-face CBT as there is a lack of therapists with the required training. As a solution to this, the use of Internet-based CBT (ICBT) has been proposed. ICBT has been shown to be effective in treatment of mild and moderate depression but has not been evaluated in persons with heart failure. Aim The overall aim of this thesis was to describe depressive symptoms over time and to develop and evaluate an ICBT intervention to treat depressive symptoms in persons with heart failure. Design and Methods The studies in this thesis employ both quantitative (Studies I, II and III) and qualitative (Studies II and IV) research methods. The sample in Study I (n=611) were recruited in the Netherlands. The participants (n=7) in Study II were recruited via advertisements in Swedish newspapers. Studies III and IV used the same cohort of participants (Study III n=50, Study IV n=13). These participants were recruited via an invitation letter sent to all persons who had made contact with healthcare services in relation to heart failure during the previous year, at the clinics of cardiology or medicine in four hospitals in southeast Sweden. Study I had a quantitative longitudinal design. Data on depressive symptoms was collected at baseline (discharge from hospital) and after 18 months. Data on mortality and hospitalisation was collected at 18 and 36 months after discharge from hospital. Study II employed three differentBehind the Screen2patterns of design, as follows: I) The development and context adaptation of the ICBT program was based on research, literature and clinical experience and performed within a multi-professional team. II) The feasibility of the program from the perspective of limited efficacy and function was investigated with a quantitative pre-post design. III) Participants’ experience of the ICBT program was investigated with a qualitative content analysis. Data on depressive symptoms was collected pre and post intervention. The time used for support and feedback was logged during the intervention, and qualitative interviews were performed with the participants after the end of the intervention. Study III was designed as a randomised controlled trial. A nine-week ICBT program adapted to persons with heart failure and depressive symptoms was tested against an online moderated discussion forum. Data on depressive symptoms, HrQoL and cardiac anxiety was collected at baseline (before the intervention started) and after the end of the intervention (approximately 10 weeks after the start of the intervention). Study IV had a qualitative design to explore and describe participants’ experiences of ICBT. The participants were recruited from within the sample in Study III and all had experience of ICBT. Data collection occurred after the ICBT program ended and was carried out using qualitative interviews by telephone. Results The mean age of the samples used in this thesis varied between 62 and 69 years of age. Concerning the symptom severity of heart failure, most persons reported New York Heart Association (NYHA) class II (40-57%) followed by NYHA class III (36-41%). Ischaemic heart disease was the most common comorbidity (36-43%). The vast majority had pharmacological treatment for their heart failure. Six percent of the persons in Study I used pharmacological antidepressants. In Studies II and III, the corresponding numbers were 43% and 18% respectively. Among persons hospitalised due to heart failure symptoms, 38% reported depressive symptoms. After 18 months, 26% reported depressive symptoms. Four different courses of depressive symptoms were identified: 1) Non-depressed 2) Remitted depressive symptoms. 3) Ongoing depressive symptoms. 4) New depressive symptoms. The highest risk for readmission to hospital and mortality was found among persons in the groups with ongoing and new depressive symptoms. A nine-week ICBT program consisting of seven modules including homework assignments on depressive symptoms for persons with heart failure was developed and tested. The RCT study (Study III) showed no significant difference in depressive symptoms between ICBT and a moderated discussion forum. Within-group analysis of depressive symptoms demonstrated a significant decrease of depressive symptoms in the ICBT group but not in the discussion forum group. The participants’ experience of ICBT was described in one theme: ICBT- an effective, but also challenging tool for self-management of health problems. This theme was constructed based on six categories: Something other than usual healthcare; Relevance and recognition; Flexible, understandable and safe; Technical problems; Improvements by live contact; Managing my life better. Conclusion After discharge from hospital, depressive symptoms decrease spontaneously among a large proportion of persons with heart failure, though depressive symptoms are still common in persons with heart failure that are community dwelling. Depressive symptoms in persons with heart failure are associated with increased risk of death and hospitalisation. The highest risks are found among persons with long-term ongoing depressive symptoms and those developing depressive symptoms while not hospitalised. ICBT for depressive symptoms in heart failure is feasible. An intervention with a nine-week guided self-help program with emphasis on behavioural activation and problem-solving skills appears to contribute to a decrease in depressive symptoms and improvement of HrQoL. When ICBT is delivered to persons with heart failure and depressive symptoms the participants requests that the ICBT is contextually adapted to health problems related to both heart failure and depressive symptoms. ICBT is experienced as a useful tool for self-care and something other than usual healthcare. ICBT also requires active participation by the persons receiving the intervention, something that was sometimes experienced as challenging.

The World Wide Web provides a well standing environment in any kind of organizations for exposing online products and services. However, no one ensures that web products or services which provided by organizations or enterprises, would receive the proper visibility and accessibility by the internet users. The process of Search Engine Optimization examines usability in design, architecture and content that an internet-based system has, for improving its visibility and accessibility in the web. Successful SEO process in an internet-based system, which is set under the paternity of an organization, ensures higher recognition, visibility and accessibility for the web services that the system provides to internet users. The aim of this study characterized with a trinity of axes. In the first axe, an internet-based system and the web services that provides is examined in order to understand its initial situation regarding its visibility and accessibility in the web. In the second axe, the study follows a user-centric approach on how and in what way the examined system could be improved based on its users’ needs and desires. After the encapsulation of needs and desires that the users expressed as regards the usability of the system in design, architecture and content, the third axe takes place. In the third axe, the extracted needs and desires of users are implemented in the under-examined system, in order to understand if its visibility and accessibility has improved in the World Wide Web.For the completion of this trinity of axes, the Soft Systems Methodology approach is adopted. SSM is an action-oriented process of inquiry which deals with a problematic situation from the Finding Out about the situation through the Taking Action to improve it. Following an interpretative research approach, ten semi-structured interviews take place in order to capture all the participants’ perceptions and different worldviews regarding of what are the changes that they need and desire from the examined system. Moreover, in this study, the conduction of three Workshops, constitute a cornerstone for implementing systemically desirable and culturally feasible changes where all participants can live with, in order to improve system’s visibility and accessibility in the internet world. The results indicate that the adoption of participants’ needs and desires, improved the levels of usability, visibility and accessibility of the under examined internet-based system. Overall, this study firstly contributes to expand the knowledge as regards the process of improving the visibility and accessibility of internet-based systems and their web services in the internet world, based on a user-centric approach. Secondly, this study works as a practical toolbox for any kind of organization which intends to improve the visibility and accessibility of its current or potential web services in the World Wide Web.

The purpose of this research was to investigate the effect that mode of test administration could have on computerised assessment results involving proctored and unproctored test conditions. Two South African test instruments, the Learning Potential Computerised Adaptive Test (LPCAT) and the Career Preference Computerised Adaptive Test (CPCAT) were used in the study. A quantitative, quasi-experimental design was used, and a convenience sample for LPCAT (N=82) and CPCAT (N=81) consisted of employees in the hospitality industry. Using a within-participants design, the dependent t-test was used for statistical analysis. For the total group the LPCAT results yielded no statistically significant differences between the mean scores for the two different modes of administration. For the total group the CPCAT results yielded statistically significant differences in the mean scores per mode of administration for five out of 34 dimensions, however, for the majority of the CPCAT sub-dimensions, the mode of administration did not impact on results. It was concluded that mode of administration did not impact on the cognitive test scores and only to a very limited degree on the non-cognitive test scores. Based on the results the null hypotheses for the effect of mode of administration were not rejected. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)
