The improvement of data acquisition and computer heavy methods in recentyears has paved the way for completely digital healthcare solutions. Digitaltherapeutics (DTx) are such solutions and are often provided as mobileapplications that must undergo clinical trials. A common method for suchapplications is to utilize cognitive behavioral-therapy (CBT), in order toprovide their patients with tools for self-improvement. The Swedish-basedcompany Alex Therapeutics is such a provider. They develop state-of-theartapplications that utilize CBT to help patients. Among their applications,they have one that aims to help users quit smoking. From this app, they havecollected user data with the goal of continuously improving their servicesthrough machine learning (ML). In their current application, they utilizemultiple ML methods to personalize the care, but have opened up possibilitiesfor the usage of reinforcement learning (RL). Often the wanted behavior isknown, such as to quitting smoking, but the optimal path, within the app, forhow to reach such a goal is not. By formalizing the problem as a Markovdecision process, where the transition probabilities have to be inferred fromuser data, such an optimal policy can be found. Standard methods of RL arereliant on direct access of an environment for sampling of data, whereas theuser data sampled from the application are to be treated as such. This thesisthus explores the possibilities of using RL on a static dataset in order to inferan optimal policy. A double deep Q-network (DDQN) was chosen as the reinforcement learningagent. The agent was trained on two different datasets and showed goodconvergence for both, using a custom metric for the task. Using SHAPvaluesthe strategy of the agent is visualized and discussed, together with themethodological challenges. Lastly, future work for the proposed methods arediscussed. / Förbättringar av datainsamling och datortunga metoder har på senare år banatväg för helt digitala vårdlösningar. Digitala terapier (DTx) är sådana lösningaroch tillhandahålls ofta som mobila applikationer. Till skillnad från andrahälsoappar måste DTx-applikationer genomgå klinisk prövning. En vanligmetod för sådana applikationer är att använda kognitiv beteendeterapi (KBT)för att ge patienter verktyg för självförbättring. Det svenskbaserade företagetAlex Therapeutics är en sådan leverantör. De utvecklar moderna applikationersom använder KBT för att hjälpa patienter. Bland deras appar har de förrökavvänjning. Från denna har de samlat in användardata med målet attkontinuerligt förbättra tjänsten via maskininlärning (ML). I sina nuvarandetillämpning använder de flera ML metoder för att personifiera vården, menhar öppnat möjligheter för användningen av Reinforcement learning (RL)(förstärkningsinlärning). Ofta är det önskade beteendet känt, t.ex att slutaröka, men den optimala vägen, inom appen, för hur man når ett sådant mål ärinte känt. Genom att formalisera problemet som en Markovsk beslutsprocess(Markov decision process), där övergångssannolikheterna måste härledas frånanvändardata, kan en sådan optimal väg hittas. Standardmetoder för RLär beroende av direktåtkomst till en miljö för att samla data. Dock skulleanvändardatan som samlats in från appen kunna behandlas på samma sätt.Detta examensarbete undersöker möjligheten att använda RL på statisk dataför att dra slutsatser om en optimal policy. Ett double deep Q-network (DDQN) (dubbelt djupt Q-nätverk) valdes somagent. Agenten tränades på 2 olika datasets och visar bra konvergens förbåda, med hjälp av ett anpassat mått för evaluering. SHAP-värden beräknadesför att visualisera agentens strategi. Detta diskuteas tillsammans med demetodologiska utmaningarna. Till sist behandlas framtida arbete för de föreslagnametoderna.

Objetivou-se verificar a viabilidade de uma proposta de aperfeiçoamento a distância para a prática psicológica no atendimento à Enurese (EN) em Serviços-escola, Unidades Básicas de Saúde e consultórios particulares, situados em diferentes regiões do país e se o tempo de experiência dos psicólogos participantes da proposta estava relacionado com algumas variáveis como: o número de contatos de supervisão, o tempo para alta dos clientes, as variações nos escores de problemas de comportamento dos clientes e da intolerância dos pais deles. Foram participantes (N=40) psicólogos de diferentes regiões do país, de ambos os sexos, divididos em dois grupos conforme sua experiência, sendo G1: menos de 10 anos (n=27) e G2: mais de 10 anos (n=13). Os participantes receberam treinamento e supervisão num programa de Educação a Distância (EAD) e atenderam crianças ou adolescentes com queixa de EN. As informações e as questões relativas ao atendimento foram comunicadas ao participante, através da internet, pela qual ele também ofereceu respostas e subsídios para sua prática. Os participantes tiveram total liberdade de consultar o supervisor quantas vezes desejassem para solucionar questões ou buscar orientação. O atendimento que desenvolveram se deu através de intervenção comportamental com uso de aparelho nacional de alarme. A Escala de Intolerância foi utilizada para avaliação dos pais, e para avaliar os filhos utilizou-se o Inventário de Comportamentos da Infância e Adolescência CBCL e o Registro simples de \"molhadas\" (descontrole enurético) ao longo do atendimento. Os resultados foram de dois tipos: dos participantes psicólogos e de seus clientes e pais. Foram comparados os números médios de contatos entre os psicólogos e o supervisor, dos dois diferentes grupos de experiência, e os escores obtidos nos instrumentos de avaliação dos clientes aplicados antes e após a intervenção, a fim de verificar a efetividade do tratamento, além do decréscimo do número de molhadas durante este. Do total de participantes, 15 concluíram o tratamento de seus clientes tendo eles atingido os critérios de sucesso e alta, dois tiveram clientes que concluíram sem sucesso, 13 descontinuaram o tratamento, quatro não conseguiram clientes e seis permanecem atendendo seus clientes que não finalizaram o tratamento ao final da coleta dessa pesquisa. O G1 atingiu alta no tratamento com uma média de 20,1 (dp=9,96) contatos para supervisão ix em 20,4 semanas(dp=5,27). O G2 alcançou alta com média de 10,0 contatos (dp=5,30) em 20,4 semanas (dp=7,13). Observou-se, nos clientes, significativa redução nos escores na escala total de problemas de comportamento dos clientes e de intolerância de seus pais em ambos os grupos de participantes após o tratamento. Os resultados deste estudo são inferiores aos obtidos no atendimento com supervisão presencial realizados no país, mas aproximam-se deles, justificando portanto o seu uso. Esses dados demonstram a viabilidade dessa modalidade de atendimento / The objective was to examine feasibility of a distance improvement program of psychological practice in treating Enuresis (EN) in School-services, Basic Health Units, and private offices, located in different areas of the country and if the amount of experience time of the participating psychologists was in any way related to variables such as: the number of supervision contacts, time for client discharge, and intolerance of their parents. Participants were (N=40) psychologists from different regions of the country, from both genders, divided into two groups according to their experience, where G1: under 10 years (N=27), and G2: over 10 years (N=13). Participants received training and supervision in a Distance Learning program (EAD) and treated children or adolescents complaining about EN. Treatment information and related questions were made known to the participant through the internet, where answers and practice aid were also offered. Participants were totally free to consult with supervisor as many times as desired to solve issues or seek guidance. Developed treatment was performed by behavioral intervention with the use of national alarm device. Throughout treatment, the Intolerance Scale was used for parent evaluation, and the Child Behavior Checklist CBCL, as well as bedwetting Record for evaluating the children. Results were of two kinds: of participating psychologists and their clients and parents. The average number of contacts between participating psychologists and their supervisors, of the two experience groups, and pre and post treatment scores obtained in client evaluation instruments were compared in order to check treatment effectiveness, as well as the decrease in bedwetting throughout it. Of the total number of participants, 15 concluded treatment with client achieving success criteria and discharge, two had clients concluding without success, 13 discontinued treatment, four did not obtain clients, and six remained treating clients who had not finish treatment at the end of data collection for this research. G1 obtained treatment discharge with an average of 20.1 (SD=9.96) contacts for supervision in 20.4 weeks (SD=5.27). G2 obtained treatment discharge with an average of 10.0 contacts (SD=5.30) in 20.4 weeks (SD=7.13). Clients were observed to have a significant decrease in total behavior problems scale scores and parent intolerance in both groups of participants xi after treatment. Results of this study are inferior to the ones obtained in treatment with face to face supervision performed in the country, but are close, therefore justifying their use. Such data demonstrates feasibility for this treatment modality

The fields of psychology and rhetoric share the goal of improving human mental health and behavior through persuasion. This thesis traces the history of rhetoric and psychology theory, focusing on the parallel theories of Nienkamp's internal rhetoric and Herman's dialogical self. Both theories model the human mind as having multiple psyches that actively interact to interpret human experience and project human behavior. I conclude with a case study of anorexic patients using ethos, pathos, and logos in dialectical behavior therapy (DBT), arguing that principles of rhetoric can help patients with mental disorders cognitively realign their thinking more effectively than drug treatments can.

Internet-based cognitive behavior therapy (ICBT) has the potential of providing many patients with an effective form of psychological treatment. However, despite helping to improve mental health and well-being, far from everyone seem to benefit. In some cases, negative effects may also emerge. The overall aim of the present thesis was to establish the occurrence and characteristics of such incidents in ICBT using a combination of quantitative and qualitative methods. Study I determined deterioration, non-response, and adverse and unwanted events in a sample of 133 patients undergoing ICBT for social anxiety disorder. The results indicated that up to 6.8% fared worse during the treatment period, depending on the self-report measure and time point, as determined using the Reliable Change Index (RCI), while the non-response rate was between 29.3 to 86.5% at post treatment assessment, and 12.9% experienced other negative effects. Study II investigated the responses to open-ended questions on adverse and unwanted events among 556 patients in four separate clinical trials of ICBT; social anxiety disorder, panic disorder, major depressive disorder, and procrastination. In total, 9.3% reported negative effects, with a qualitative content analysis revealing two categories and four subcategories; patient-related, i.e., gaining insight and experiencing new symptoms, and treatment-related, i.e., difficulties applying the treatment interventions and problems related to the treatment format. Study III explored the number of patients achieving reliable deterioration, as determined using the RCI on the individual raw scores of 2866 patients from 29 clinical trials of ICBT. The results showed that the deterioration rate was higher among patients in a control condition, 17.4%, in comparison to treatment, 5.8%. Predictors were related to decreased odds of deterioration for patients receiving treatment; clinical severity at pre treatment assessment, being in a relationship, having a university degree, and being older. As for the control condition, only clinical severity at pre treatment assessment was associated with decreased odds of deterioration. Study IV examined a newly developed self-report measure for monitoring and reporting adverse and unwanted events, the Negative Effects Questionnaire. The results suggested a six-factor solution with 32 items; symptoms, quality, dependency, stigma, hopelessness, and failure. One-third of the patients reported experiencing unpleasant memories, stress, and anxiety, with novel symptoms and a lack of quality in the treatment and therapeutic relationship having the greatest negative impact. The general finding of the present thesis is that negative effects do occur in ICBT and that they are characterized by deterioration, non-response, and adverse and unwanted events, similar to psychological treatments delivered face-to-face. Researchers and clinicians in ICBT are recommended to monitor and report negative effects to prevent a negative treatment trend and further the understanding of what might contribute to their incidents. Future research should investigate the relationship between negative effects and treatment outcome, especially at follow-up, to examine if they are transient or enduring. Also, interviews could be conducted with those achieving reliable deterioration to explore if and how it is experienced by the patients and to see if it is attributed to the treatment interventions or other circumstances. / Internetbaserad kognitiv beteendeterapi (IKBT) har goda förutsättningar att kunna bli en form av psykologisk behandling som på ett effektivt sätt hjälper patienter med att hantera sin psykiska ohälsa och förbättra sitt välmående. Trots detta är det dock långtifrån alla som tycks bli bättre. För en del kan det till och med resultera i negativa effekter. Det övergripande syftet med denna avhandling har således varit att undersöka förekomsten av sådana fall och hur dessa uttrycks, såväl med kvantitativa som kvalitativa metoder. Studie I fastställde andelen försämrade, oförändrade samt andra ogynnsamma eller oönskade händelser bland 133 personer som behandlades med IKBT för social ångest. Resultatet visade att uppemot 6,8 % försämrades under sin behandlingsperiod beroende på vilket självskattningsformulär respektive tidpunkt som studerades, beräknat enligt metoden Reliable Change Index (RCI). Likaså var 29,3 % till 86,5 % oförändrade vid eftermätningen samt att 12,9 % rapporterade andra former av negativa effekter. Studie II undersökte svaren på öppna frågor som gällde ogynnsamma eller oönskade händelser bland 556 patienter i fyra olika kliniska studier med IKBT; social ångest, paniksyndrom, egentlig depressionsepisod och prokrastinering. Totalt sett rapporterade 9,3 % att de hade erfarit negativa effekter, vilka analyserades med hjälp av kvalitativ innehållsanalys. Två övergripande kategorier och fyra subkategorier framkom; patientrelaterade, som ökad insikt respektive nya symptom, samt behandlingsrelaterade, som svårigheter att implementera behandlingsinterventionerna respektive problem med behandlingsformatet. Studie III utrönte andelen patienter som försämrades i enlighet med RCI, baserat på insamlad rådata från 2866 personer i 29 olika kliniska studier med IKBT. Resultatet visade att försämring var mer förekommande hos de som var i en kontrollgrupp, 17,4 %, jämfört med de som fick behandling, 5,8 %. Bland de som genomgick behandling existerade det även ett par prediktorer som innebar lägre odds för försämring; större svårigheter vid förmätningen, att befinna sig i en relation, att ha en universitetsutbildning respektive att vara äldre. För de som var i en kontrollgrupp var enbart större svårigheter vid förmätningen relaterat till lägre odds för försämring. Studie IV testade ett nykonstruerat självskattningsformulär; Negative Effects Questionnaire. Resultatet visade på en faktorlösning med sex faktorer och 32 påståenden; symptom, kvalitet, beroende, stigma, hopplöshet respektive misslyckande. En tredjedel av personerna svarade att de hade upplevt obehagliga minnen, stress och ångest, samtidigt som nya symptom och bristande kvalitet i både behandlingen respektive den terapeutiska relationen hade haft störst negativ inverkan på dem. Den generella slutsatsen av denna avhandling är således att negativa effekter förekommer i IKBT och att de kännetecknas av försämring, ett oförändrat tillstånd samt andra ogynnsamma eller oönskade händelser, något som liknar tidigare forskning av psykologisk behandling som bedrivs ansikte-mot-ansikte. Forskare och behandlare i IKBT rekommenderas att övervaka och rapportera negativa effekter i syfte att förhindra en negativ utveckling i behandlingen samt för att öka kunskapen om vad som kan bidra till deras förekomst. Framtida forskning bör undersöka relationen mellan negativa effekter och behandlingsutfall utifrån längre tidsperspektiv för att se om dess påverkan är övergående eller ihållande. Vidare kan till exempel intervjuer utföras med de patienter som har försämrats för att ta reda på om och hur det uppfattas samt huruvida det har förorsakats av behandlingen eller andra omständigheter. / <p>At the time of the doctoral defense, the following paper was unpublished and had a status as follows: Paper 4: In press.</p>

Text in English / In order to address the paucity of knowledge in regard to the psychological and physiological processes associated with lifelong weight loss (>20 years), this study adopts a qualitative approach informed by phenomenology to explore the experience of lifelong weight loss and maintenance of women who participated in the ITAND Programme. The research questions guiding the exploration of the current research are: (i) Which strategies from the ITAND Programme do women perceive as assisting with initial weight loss? (ii) What are the processes mediating lifelong weight loss? (iii) What strategies and skills mediate the maintenance of lifelong weight loss? (iv) What feelings or beliefs motivate women to continue attempts to lose weight after experiencing multiple failures on diets? and (v) Which psychological, cognitive and behavioural processes are identified as mediating lifelong weight loss? Eight overweight and obese women were invited to write their narratives and engage in interviews in regard to exploring their relationships with food, their bodies and their weight, after a period of more than 20 years following their participation in an integrative, transactional analysis, anti-diet programme (the ITAND Programme). Narratives were used to explore their beliefs about constructs, processes and strategies mediating long-term weight loss maintenance. The participants’ narratives and interviews were analysed through applying narrative analysis and interpretive phenomenological analysis. In addition to a non-diet paradigm, four processes definingweight loss maintenance were identified, including the adult learning process of transformative learning, the psychological process of transactional analysis, the physiological process of intuitive eating and the cognitive-behavioural processes relating to weight loss maintenance. This study contributes an integrative, transactional analysis, non-diet treatment model (ITAND model) which is enabled by the processes of transformative learning, intuitive eating and cognitive-behaviour modification to the successful long- term treatment of overweight and obesity. This model may be applied in whole or in part in a primary health care or community context. The findings of this study may be used to inform future research into the development and implementation of non-diet weight loss maintenance interventions in the treatment of overweight andobesity. / Psychology / D.Litt. et Phil.
