Worry Exposure versus Applied Relaxation in the Treatment of Generalized Anxiety Disorder

Hoyer, Jürgen, Beesdo, Katja, Gloster, Andrew T., Runge, Juliane, Höfler, Michael, Becker, Eni S. 13 February 2014 (has links) (PDF)
Background: Worry exposure (WE) is a core element of cognitive-behavioral treatment for generalized anxiety disorder (GAD). Its efficacy as a stand-alone treatment method (without further cognitive-behavioral therapy interventions) has never been tested.We aimed to examine whether WE alone is as efficacious as the empirically supported stand-alone treatment for GAD, applied relaxation (AR). Methods: In a randomized controlled study, 73 outpatients meeting DSM-IV criteria for GAD as primary diagnosis were allocated to either WE or AR or a waiting list control group; in a 2nd randomization procedure the waiting list subjects were reallocated to WE or AR. The treatment was manualized (15 sessions with WE or AR), included 6-month and 1-year follow-ups, as well as last observation carried forward and completer analyses, and was controlled for allegiance effects.The Hamilton Anxiety Rating Scale and the State-Trait Anxiety Scale were used as primary outcome measures. Self-report scales of anxiety, worrying and depression including negative metacognition about worrying and thought suppression served as secondary outcome measures. Results: The dropout rate was moderate. The pre-/posttreatment effects were high for the Hamilton Anxiety Rating Scale (standardized mean difference >1) and for the State-Trait Anxiety Inventory (standardized mean difference >0.87). The proportion of patients reaching high end state functioning was 48% (WE) and 56% (AR). WE and AR did not differ with regard to dropout rate or treatment effects. The treatment effects were stable at 6 month and 1 year follow-up. Conclusion: This is the first study to show that a stand-alone exposure in sensu technique – WE – is efficacious in the treatment of GAD. Both AR and WE seem to represent effective principles of change in GAD. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

O Labirinto em T elevado (LTE) é um teste que avalia separadamente dois subtipos de ansiedade: a ansiedade generalizada e o pânico, respectivamente através da avaliação dos comportamentos defensivos de esquivas inibitórias e das fugas. Assim, este estudo teve por objetivo investigar o envolvimento de receptores 5-HT1A no HV sobre a manifestação dos transtornos de ansiedade generalizada (TAG) e pânico (TP) no LTE, tendo como parâmetro a ativação de receptores gabaérgicos (GABAA) nessa área do hipocampo. Foram conduzidos dois experimentos em ratos Wistar: o Experimento 1, visando avaliar o efeito do midazolam (10, 20 ou 40nmol) - um benzodiazepínico que potencializa a ação do GABA em receptores GABAA; e o Experimento 2, para avaliar o efeito de 8-OH-DPAT (0,6, 3 ou 15nmol) – um agonista de receptores 5-HT1A. Animais dos grupos controles nos dois experimentos foram tratados com salina. Dez minutos após as microinjeções foram submetidos ao LTE para avaliação das latências (em segundos) para esquivas e fugas. Imediatamente após, os animais foram colocados no centro da arena para avaliação da atividade motora (número de quadrados percorridos). Os resultados apontaram que a maior dose de midazolam microinjetada no hipocampo ventral causou ansiólise, comprovada pela diminuição na latência das esquivas em relação aos animais controles e àqueles tratados com 10nmol do mesmo fármaco. Resultado semelhante foi constatado nas três doses de 8-OH-DPAT. Não se observou qualquer alteração nas fugas, e nem na atividade motora dos animais tratados com qualquer um dos fármacos testados. Essas evidências comportamentais indicam que a ativação de receptores 5-HT1A no HV diminuiu o comportamento de esquiva dos animais, sem afetar as respostas de fugas, semelhantemente ao que se observou em decorrência da ação do midazolam sobre receptores GABAA. Esses resultados indicam um envolvimento desses receptores na regulação do TAG, mas não do TP. / The little is known about the serotoninergic activity on 5-HT1A receptors in the ventral hippocampus in the regulation of different types of anxiety. The Elevated T Maze (ETM) is a test that evaluates separately two subtypes of anxiety: generalized anxiety and panic, respectively by evaluating the defensive behaviors of inhibitory avoidance and escapes. Therefore this study aimed to investigate the involvement of 5-HT1A receptors in VH on the manifestation of generalized anxiety disorder (GAD) and Panic (PD) in ETM, having as parameter the activation of gabaergic receptors (GABAA) in that area of the hippocampus. Two experiments were conducted in rats: Experiment 1, to evaluate the effect of midazolam (10, 20 or 40nmol) – a benzodiazepine that potentiates the action of the GABA on GABAA receptors; and Experiment 2 to evaluate the effect of 8-OH-DPAT (0.6, 3 or 15nmol) - an agonist of 5-HT1A receptors. Animal control groups in both experiments were treated with saline. Ten minutes after microinjection, the animals were submitted for evaluation to the ETM latencies (in seconds) for avoidances and escapes. Immediately after, the animals were placed in the center of the arena to eavaluation of motor activity (number of covered squares). The results showed that the highest dose of midazolam microinjected in the ventral hippocampus caused anxiolysis, evidenced by the decrease in latency of avoidances compared to controls and those treated animals 10nmol of the same drug. A similar result was observed at all three doses of 8-OH-DPAT. There was no change in the escapes, nor the motor activity of animals treated with any of the drugs tested. These behavioral evidence indicates that activation of 5-HT1A receptors in VH decreases the behavior of avoidance of the animals without affecting the escape response, similar to what was observed due to the action of midazolam on the GABAA receptors. These results indicate an involvement of these receptors in the regulation of GAD, but not of PD.

O conflito trabalho-família, que emerge da incompatibilidade das demandas entre estas esferas, tem sido associado a efeitos deletérios à saúde, afetando de forma assimétrica mulheres e homens. Há escassez de estudos desta natureza no Brasil e a realização desta investigação com dados do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) pretendeu contribuir para o conhecimento sobre determinantes sociais da saúde de adultos brasileiros, sob a perspectiva de gênero. O objetivo foi analisar as associações entre conflito trabalho-família e excesso de peso corporal e ansiedade em mulheres e homens no Brasil. Foram utilizados dados da linha de base da coorte ELSA-Brasil, realizada entre 2008 e 2010, quando foram coletados entrevistas, medidas e exames clínicos. Foram escolhidas e incluídas nas análises variáveis relacionadas aos domínios do trabalho e da família. Foram realizadas análises psicométricas de itens para mensurar o construto conflito trabalho-família, além de modelos de regressão logística para testes de associação entre exposição e desfechos. As análises foram estratificadas por sexo. Gênero foi a categoria analítica que orientou as discussões dos resultados, que estão apresentados sob a forma de três artigos para publicação em revistas de circulação nacional e internacional. O primeiro artigo apresenta a análise de propriedades psicométricas dos itens para mensuração do conflito entre trabalho e família, cujos resultados foram aceitáveis e deram origem às variáveis de exposição dos demais artigos. No segundo artigo foi testada a hipótese de associação entre conflito trabalho-família-tempo para si e transtorno de ansiedade generalizada (TAG). Os resultados evidenciaram associação positiva entre a percepção de alto conflito trabalho-família-tempo para si e TAG, de maior magnitude entre as mulheres. No terceiro artigo realizou-se o teste da hipótese de associação entre tempo insuficiente para cuidado pessoal e lazer e o excesso de peso corporal. Evidenciou-se associação positiva entre tempo insuficiente para o cuidado pessoal e lazer e a ocorrência de sobrepeso e obesidade entre mulheres que referiram maior jornada semanal de trabalho profissional. A abordagem do conflito entre trabalho e família e sua relação com desfechos de saúde deve ser aprofundada em estudos futuros.

Os efeitos desejados ocorrem somente após administração crônica, em torno de 3 a 4 semanas após o início do tratamento, com aumento dos sintomas de ansiedade no início da terapia farmacológica, ocasionando a descontinuidade do uso desses fármacos. Além disso, há relatos de resistência a esse tipo de tratamento. Visando encontrar soluções para tais problemas, fundamentados em estudos que mostraram que mecanismos opioides favorecem a atividade inibitória da serotonina em neurônios da Substância Cinzenta Pereiaquedutal Dorsal que modulam a fuga/pânico, o presente estudo teve por objetivo investigar o efeito da Buprenorfina, um agonista parcial de receptores µ-opioide e antagonista de receptores κ-opioide, como agente ansiolítico e anti-pânico, como também avaliar se o efeito ansiolítico e antipânico da Fluoxetina seriam antecipados pela associação com a Buprenorfina. Foram realizados 3 experimentos utilizando ratos machos Wistar com peso médio de 200g no início das sessões experimentais: 1. Tratamento agudo com Buprenorfina IP nas doses (0,015mg/Kg, 0,03mg/Kg 0,3mg/Kg), tendo como controle positivo o Alprazolam IP (4mg/Kg); 2. Tratamento subcrônico 3 dias com Buprenorfina IP (0,3mg/Kg); 3. Tratamento agudo com Buprenorfina (0,3mg/Kg) - associado ao tratamento subcrônico com Fluoxetina 3 dias IP, (10mg/Kg). Após os tratamentos, os animais foram submetidos à avaliação comportamental no Labirinto em T Elevado (LTE) e, subsequentemente, ao Campo Aberto e no Teste de Transição Claro-Escuro. No experimento 1 o teste comportamental foi repetido 24 horas após a primeira avaliação comportamental. Os resultados mostraram que a Buprenorfina nas doses maiores diminuiu a latência das esquivas, sem alteração das fugas no LTE, diferentemente do que se constatou no tratamento agudo com o Alprazolam, o qual diminuiu também as esquivas, mas aumentou a latência nas fugas, efeitos esses interpretados respectivamente como, ansiolítico e panicolítico. Vinte e quatro horas depois não se constatou mais efeito do Alprazolam, e o efeito da Buprenorfina sobre as esquivas só foi identificado na maior dose e apenas na LB. Em nenhuma das duas situações houve aumento de atividade motora. No teste de Transição Claro-Escuro não se constatou efeito expressivo nas condições estudadas, apenas possibilitou a escolha da maior dose para a continuidade do estudo, já que a intermediária aumentou a atividade motora nesse teste 24h após a injeção. A Buprenorfina administrada subcronicamente também diminuiu as esquivas, sem afetar a latência das fugas e o comportamento motor no campo aberto. Também não se identificou alterações no Teste de Transição Claro-escuro. A Buprenorfina antecipou o efeito ansiolítico da Fluoxetina, sem afetar as respostas relacionadas com a manifestação do pânico. Entretanto não houve confirmação dos achados no outro teste de ansiedade. Conclui-se que a Buprenorfina, administrada de forma aguda e subcrônica, diminuiu os comportamentos defensivos relacionados com a ansiedade generalizada, e antecipou o efeito ansiolítico da Fluoxetina, podendo se constituir em uma opção relevante no tratamento dos transtornos de ansiedade na clínica, devido à sua baixa capacidade de causar efeitos adversos e também diante da possibilidade de antecipar os efeitos benéficos da fluoxetina, apenas com uma injeção / Antidepressant drugs such as selective serotonin reuptake inhibitors are used in the treatment of anxiety, panic and other mental disorders. The desired effects occur only after chronic administration, around 3 to 4 weeks after starting treatment, with increased anxiety symptoms at the beginning of pharmacological therapy, causing the discontinuation of the use of these drugs. In addition, there are reports of resistance to this type of treatment. Aiming to find solutions for such problems, based on studies that showed that opioid mechanisms favor the serotonin inhibitory activity in SCPD neurons that modulate scape / panic, the present study aimed to investigate the effect of Buprenorphine, a partial agonist of μ receptors - opioid and antagonist κ receptor - opioid as anxiolytic and anti-panic agents as well as assessing whether the anxiolytic and antipanic effect of Fluoxetine would be anticipated by association with Buprenorphine.Three experiments were performed using male Wistar rats weighing 200g at the beginning of the experimental sessions: 1. Acute treatment with Buprenorphine IP at doses (0,015mg / kg, 0,03mg / kg 0,3mg / kg) or Alprazolam IP (4mg / kg); 2. Subchronic treatment 3 days with Buprenorphine IP (0,3mg / kg); 3. Acute treatment with Buprenorphine (0,3mg / kg) - associated to the subchronic treatment with Fluoxetine 3 days IP, (10mg / kg). After the treatments, the animals were submitted to behavioral evaluation in the elevated T maze (LTE) and subsequently to the Open Field and the Light-Dark Transition Test. In experiment 1 the behavioral test was repeated 24 hours after the first behavioral evaluation. The results showed that Buprenorphine in the larger doses decreased the manifestation of the elusions, without alterations of the scapes in the LTE, differently from what was observed in the acute treatment with Alprazolam, which also reduced the elusive ones, but increased the latency in the scapes, interpreted respectively as anxiolytic and panicolitic. Twenty-four hours later no effect of Alprazolam was found, and the effect of Buprenorphine on the avoidance was only identified at the highest dose and only at LB. There was no increase in motor activity in either of the two situations. In the Light-Dark Transition test, no significant effect was observed in the conditions studied, it only allowed the choice of the highest dose for the continuity of the study, since the intermediary increased the motor activity in this test 24 hours after the injection.Subchronic administration of buprenorphine also decreased the avoidances without affecting the scapes and motor behavior in the open field. Also, no changes were identified in the Light-Dark Transition Test. Buprenorphine anticipated the anxiolytic effect of Fluoxetine, without affecting the responses related to the manifestation of panic. However, there was no confirmation of the findings in the other anxiety test. It was concluded that acute and subchronic administration of Buprenorphine decreased the defensive behaviors related to generalized anxiety, and anticipated the anxiolytic effect of Fluoxetine, which may constitute a relevant option in the treatment of anxiety disorders in the clinic due to the its low ability to cause adverse effects and also the possibility of anticipating the beneficial effects of fluoxetine with an injection alone

No entanto, apesar de eficazes na terapêutica, esses fármacos apresentam limitações no seu uso, tais como: os efeitos desejados ocorrem somente após administração crônica, em torno de 3 a 4 semanas após o início do tratamento; a proporção relativamente alta de pacientes que não respondem à medicação e o frequente aumento nos níveis de ansiedade desse pacientes no início do tratamento, levando à descontinuidade do uso destas drogas. Nesse sentido, há grande interesse na busca de novas estratégias de tratamento, identificando outros sistemas de neurotransmissão que possam estar relacionados à etiologia e, consequentemente, ao tratamento desses transtornos de ansiedade. Estudos prévios apontaram o envolvimento de opioides endógenos na modulação da ansiedade. Mais especificamente em relação ao TP, já se constatou que mecanismos opioides favorecem a atividade inibitória da serotonina em neurônios da Substância Cinzenta Periaquedutal Dorsal (SCPD) que modulam a fuga/pânico, possivelmente por meio da formação de heterodímeros entre receptores 5-HT1A e μ-opioide. Com base em tais aspectos, o presente estudo teve por objetivo investigar o efeito da Buprenorfina, um agonista parcial de receptores µ-opioide e antagonista de receptores κ-opioide, sobre a manifestação de comportamentos defensivos relacionados com o TAG e com o TP. O uso de agonistas parciais justifica-se pela possibilidade de atenuar efeitos adversos sobrevindos do uso contínuo de agonistas plenos para os receptores µ-opioide, tais como a euforia, a tolerância e a dependência. Para isto, foram conduzidos dois experimentos utilizando ratos Wistar, seguindo-se em cada um deles dois tipos de avaliação: Teste de analgesia, como parâmetro da eficácia do fármaco e testes comportamentais Labirinto em T Elevado (LTE), Campo Aberto e Transição Claro-Escuro. No primeiro experimento foi implantado cirurgicamente um adesivo de Buprenorfina (5mg) entre a pele e o tecido subcutâneo, cujas avaliações foram conduzidas 27 horas após o implante. No segundo experimento utilizou-se um extrato liofilizado da Buprenorfina a partir dos adesivos, em 3 doses diferentes: 1,5 mg/kg; 3,0 mg/kg; 6,0 mg/kg. Todas as avaliações ocorreram 10 minutos após as injeções intraperitoneais. Os resultados mostraram que a Buprenorfina nas doses e vias estudadas desinibiu o comportamento de esquivas inibitórias no LTE e o comportamento motor dos ratos no Teste do Campo Aberto, mas não afetou as fugas no LTE e nem outras manifestações comportamentais no Teste de Transição Claro-Escuro, exceto no implante do adesivo, quando se observou ansiólise nesse teste. Na administração por via IP, esses resultados ocorreram em todos os testes, mas somente na reexposição, 24 horas após a primeira avaliação comportamental. Em conclusão, a Buprenorfina nas doses e vias estudadas apresentou efeito analgésico e desinibiu o comportamento de esquivas e o comportamento motor dos ratos, mas não afetou as fugas, o que indica seu envolvimento na modulação de comportamentos defensivos apenas relacionados com a manifestação da ansiedade generalizada. Nesta dissertação, para maior aprofundamento do tema, foi inicialmente apresentada uma fundamentação teórica geral sobre as variáveis sob foco de investigação. Na sequência, foi exposto um artigo contendo uma fundamentação teórica mais específica, a descrição metodológica, bem como a análise e discussão dos resultados dos experimentos realizados. / Antidepressant drugs such as the selective serotonin reuptake inhibitors (SSRI; examples: fluoxetine and escitalopram) are first choice drugs for treating Generalized Anxiety Disorders (GAD) and Panic Disorder (PD). However, in spite of being therapeutically effective, such drugs present use limitations, such as: the desired effects occur only after chronic administration, within 3 to 4 weeks after the beginning of treatment; a relatively high proportion of patients who do not respond to the drug and the frequent increase of anxiety levels of such patients at the beginning of the treatment, leading to discontinuity in the use of such drugs. Along these lines, there is a great interest in the search of new treatment strategies, identifying other neurotransmission systems which may be related to the etiology and, consequently, to the treatment of such anxiety disorders. Previous studies pointed to the involvement of endogenous opioids in anxiety modulation. More specifically in relation to PD, one has found out that opioid mechanisms favor the inhibitory activity of serotonin in periaqueductal grey matter (dPAG) neurons which modulate escape/panic, probably by means of the formation of heterodimers between 5-HT1A and μ-opioide receptors. Based on such features, this study was carried out aiming at investigating buprenorfine effects, a partial μ-opioide receptor agonist and κ- opioidereceptor antagonist, on the manifestation of defensive behaviors related to GAD and PD. The use of partial agonists is justified by the possibility of attenuating adverse effects occurred after the continuous use of full agonists for μ- opioidereceptors, such as euphoria, tolerance and dependence. Therefore, two experiments werecarread out using Wistar rat, each one followed by two assessment types: analgesia test, as efficiency parameter of the drug and behavioral tests the elevated T-maze (ETM), Open Field and Light-Dark Transition. In the first experiment was surgically implanted a buprenorfine patch (5 mg) between the skin and the subcutaneous tissue, whose assessments were carried out 27 hours after the implantation. In the second experiment was used a buprenorfine extract based on the patches, with three different doses: 1.5 mg/kg; 3.0 mg/kg; 6.0 mg/kg. All the assessments were carried out 10 minutes after the intra-peritoneal injections. The results showed that buprenorfine administered in the studied doses and means uninhibited the inhibiting escape behavior in LTE and the motor behavior of rat in the Open Field Test, but did not affect escapes in LTE nor in other behavioral manifestations in the Light-Dark Transition Test, with the exception of the patch implant, when we were observed anxiolysis in this test. In the IP administration, such results occurredin all the tests, but only in the re-exposure, 24 hours after the first behavioral assessment. In conclusion, buprenorfine administered in doses and methods produced analgesic effect and impaired of the avoidance, but did not affected the escapes, which shows the involvement of this drug in the modulation of defensive behaviors only related whit manifestation of generalized anxiety. In this dissertation, presented a general theoretical foundation on the variables focused on the investigation and afterwards, a paper with a more specific theoretical foundation, the methodological description, as well as the analysis and discussion of the results yielded in the conducted experiments.

Generalized anxiety disorder and health care utilization

Kujanpää, T. (Tero) 02 August 2016 (has links)
Abstract Generalized anxiety disorder (GAD) is a mental health problem, which is characterized by excessive anxiety and worry, problems that are difficult to control. In the general population, the 12-month prevalence of GAD is 2-3%, with the lifetime prevalence being about 5%. However, GAD is more prevalent among primary care utilizers i.e. approximately 5-8% of them suffer from this disorder. Earlier studies have revealed GAD to be associated with a high utilization of health care resources. There were four goals of the present study; i) to investigate the prevalence of GAD among Finnish health care high utilizers, ii) to examine the association between GAD and utilization of different health care services at the population level, iii) to determine whether there would be any association between frequent utilization of health care services, GAD and somatic symptoms and iv) to compare the costs associated with GAD in secondary care in Finland with those attributable to major depressive disorder (MDD). In addition, the Finnish translation of the 7-item GAD scale (GAD-7) was validated. In a sample (n=150) of health care high utilizers in northern Finland, the prevalence of GAD was found to be 4%; GAD-7 was a valid instrument for detecting GAD in these subjects. In Northern Finland 1966 Birth Cohort, there was a significant association between GAD and health care utilization. Those subjects who screened positive for GAD with GAD-7 made 112% more total health care visits than other individuals. The results were statistically significant when controlled for potential confounders. Both GAD symptoms and physical symptoms were risk factors for frequent attendance of health care services, and the individuals who tested positive for GAD exhibited a higher rate of physical symptoms. Secondary care costs of all patients with a new diagnosis of GAD or MDD were calculated 2 years before and after the diagnosis date using the information from the Finnish Hospital Discharge Registers and National Hospital Benchmarking Database. Patients with a history of earlier depression or anxiety disorder had markedly higher costs compared with patients without psychiatric comorbidities. The highest mean individual costs (€19,538) during the 4-year follow-up were observed among patients with new onset of GAD but with a history of other anxiety disorders or MDD. / Tiivistelmä Yleistynyt ahdistuneisuushäiriö on mielenterveyden häiriö, jolle on ominaista ylenmääräinen ahdistuneisuus ja huolestuneisuus, joita on vaikea kontrolloida.

Perusterveydenhuoltoon hakeutuvilla potilailla sen on todettu olevan muuta väestöä yleisempi n. 5-8 %:n täyttäessä diagnostiset kriteerit. Aiemmat tutkimukset ovat viitanneet yleistyneestä ahdistuneisuushäiriöstä kärsivien käyttävän usein runsaasti terveyspalveluita. Tämän tutkimuksen tarkoituksena oli selvittää yleistyneen ahdistuneisuushäiriön esiintyvyyttä terveyspalveluita paljon käyttävillä suomalaisilla henkilöillä, yleistyneen ahdistuneisuushäiriön yhteyttä erilaisten terveyspalveluiden käyttöön väestötasolla, yleistyneen ahdistuneisuushäiriön ja somaattisten oireiden yhteyttä terveyspalveluiden suurkäyttöön ja yleistyneeseen ahdistuneisuushäiriöön erikoissairaanhoidossa liittyviä kustannuksia vertaillen niitä masennukseen liittyviin kustannuksiin. Samalla validoitiin yleistyneen ahdistuneisuushäiriön seulontaan kehitetyn GAD-7 seulan suomenkielinen käännös. Joukossa pohjoissuomalaisia (n=150) terveyspalveluita paljon käyttäviä henkilöitä 4 %:lla todettiin yleistynyt ahdistuneisuushäiriö. Heillä GAD-7-kysely osoittautui toimivaksi seulontatyökaluksi. Pohjois-Suomen 1966 syntymäkohortissa väestötasolla tutkittaessa todettiin yleistyneeseen ahdistuneisuushäiriöön liittyvän runsasta terveyspalveluiden käyttöä. GAD-7-kyselyssä positiivisen testituloksen saaneilla oli kokonaisuudessaan 112 % enemmän terveyspalveluiden käyttöä. Tulokset olivat tilastollisesti merkitseviä myös huomioitaessa mahdolliset sekoittavat tekijät. Lisäksi sekä yleistynyt ahdistuneisuushäiriö että somaattiset oireet liittyivät terveyspalveluiden suurkäyttöön. Sairaaloiden poistoilmoitusrekisteriä ja kansallista sairaaloiden vertailutietokantaa hyödyntäen laskettiin uusien yleistyneen ahdistuneisuushäiriön ja masennuksen diagnoosin saaneiden potilaiden erikoissairaanhoidon kokonaiskustannukset 2 vuotta ennen ja jälkeen diagnoosin. Erityisen suuret kustannukset olivat niillä uuden diagnoosin saaneilla, joilla oli historiassa aiempi masennus tai ahdistuneisuushäiriö. Suurimmat keskimääräiset erikoissairaanhoidon kustannukset (19 538 €) todettiin niillä yliestyneen ahdistuneisuushäiriön diagnoosin saaneilla, joilla aiemmin oli todettu jokin muu ahdistuneisuushäiriö tai masennus.

The short- and long-term effect of duloxetine on painful physical symptoms in patients with generalized anxiety disorder: Results from three clinical trials

Beesdo, Katja, Hartford, James, Russell, James, Spann, Melissa, Ball, Susan, Wittchen, Hans-Ulrich January 2009 (has links)
Generalized anxiety disorder (GAD) is associated with painful physical symptoms (PPS). These post hoc analyses of previous trial data assessed PPS and their response to duloxetine treatment in GAD patients. Studies 1 and 2 (n = 840) were 9- to 10-week efficacy trials; study 3 (n = 887) was a relapse prevention trial comprising a 26-week open-label treatment phase and a 26-week double-blind, placebo-controlled treatment continuation phase. Mean baseline visual analog scale scores (VAS, 0–100; n = 1727) ranged from 26 to 37 for overall pain, headache, back pain, shoulder pain, interference with daily activities, and time in pain while awake. In studies 1 and 2, improvement on all VAS scores was greater in duloxetine-treated than in placebo-treated patients (p ≤ 0.01). In study 3, pain symptoms worsened in responders switched to placebo compared with those maintained on duloxetine (p ≤ 0.02). In conclusion, duloxetine was efficacious in the short- and long-term treatment of PPS, which are common in GAD patients.

”Allergi mot ovisshet” : En kvalitativ dokumentstudie av målgruppens egna upplevelser av generaliserat ångestsyndrom (GAD) / "Allergy to uncertainty" : A qualitative documentary study of the target group's own experiences of Generalized Anxiety Disorder (GAD)

Jörgensen, Sofie, Rootzén, Andréas January 2022 (has links)
This study aims to gain an increased understanding of generalized anxiety disorder based on how the target group describe their experiences. The data was gathered through podcasts where people with GAD talked about their life situation, what strategies they use to manage general anxiety and what they think relieves general anxiety. The gathered data was then analyzed through a thematic analysis where four main themes were developed; a constant worry, managing stigma, controlling or avoiding and only relive, not cure. These themes were analyzed based on Goffman's theory of stigma and Gidden's theory of the risk society. The results show that people with GAD live with a constant anxiety that affects their entire life situation, such as their work, leisure, and social relationships. Their anxiety can be likened to an allergy to uncertainty as it´s triggered by something they cannot control. They feel stigmatized by others and feel that they often need to hide their stigma by living behind a facade. To deal with generalized anxiety, three different strategies are used, which are trying to control everything, avoiding anxiety by not exposing oneself to things that cause concern or by keeping oneself busy. However, these strategies can aggravate the condition but there are many things that can relieve general anxiety. The most prominent factors are medicine, therapy, emotional support and self-help such as exercise and meditation. But the results show that the symptoms persist despite great efforts and several treatments, which indicates that more research and more effective interventions are required. The study concludes that GAD is not only a problem that exists within the individual but also in interpersonal relationships and in the society. It also concludes that there must be a change in the structures of society regarding mental illness, and that interventions should not only be directed towards the individual but also towards the relatives. This because the results show that relatives are also affected and that their influence can both aggravate and improve the individual's condition. / Den här studien syftar till att få en ökad förståelse för generaliserat ångestsyndrom utifrån hur målgruppen själva beskriver sina upplevelser. Empirin samlades in genom poddar där personer med GAD berättade om sin livssituation, vilka strategier de använder för att hantera generell ångest och vad de anser lindrar generell ångest. Materialet analyserades genom en tematisk analys där fyra huvudteman togs fram; en konstant oro, hantera stigma, kontrollera eller undvika och endast lindra inte bota. Dessa teman analyserades utifrån Goffmans stigmateori och Giddens risksamhällesteori. Resultatet visar att personer med GAD lever med en konstant oro som påverkar hela deras livssituation, så som deras arbete, fritid och sociala relationer. Deras oro kan liknas med en allergi mot ovisshet då den triggas av sådant de inte kan kontrollera. De upplever sig stigmatiserade av andra och känner att de ofta behöver dölja sitt stigma genom att leva bakom en fasad. För att hantera generaliserad ångest används tre olika strategier vilka är att försöka kontrollera allt eller att undvika ångesten genom att inte utsätta sig för sådant som väcker oro eller att ständigt aktivera sig. Dessa strategier kan dock förvärra tillståndet, men det finns mycket som kan lindra generell ångest. De mest framträdande faktorerna är medicin, terapi, emotionellt stöd och självhjälp, som exempelvis meditation och träning. Resultatet visar dock att symtomen kvarstår trots stora ansträngningar och flertalet behandlingar vilket tyder på att mer forskning och effektivare interventioner krävs. Studien konkluderar att GAD inte enbart är ett problem som existerar inom individen utan även i mellanmänskliga relationer och i samhället som helhet. Därmed dras också slutsatsen att det måste ske en förändring i samhällsstrukturerna avseende psykisk ohälsa och att interventioner inte enbart bör riktas mot individen utan även anhöriga. Detta då resultatet visar att anhöriga också påverkas och att deras inflytande både kan förvärra och förbättra individens tillstånd.

Sociala medier, självkänsla och ångestsymptom hos högstadieflickor

Raderius, Natalie January 2024 (has links)
Det finns en växande oro för den inverkan som sociala medier har på ungas psykiska hälsa. Sociala jämförelser och orealistiska skönhetsideal nämns ofta i relation till sådana samband. Flickor i tonåren rapporterar högre förekomst av psykiska besvär samt lägre självkänsla än pojkar. Syftet med föreliggande studie var att undersöka högstadieflickors användning av sociala medier (med fokus på Instagram och Snapchat) och huruvida denna är associerad med generaliserad ångest. Medieringsanalys användes för att testa om självkänsla kunde förklara det potentiella sambandet bland ett slumpmässigt urval unga flickor i Stockholms län (N = 1161; medelålder = 14 år). Urvalet baseras på sekundärdata från en studie av Nationellt centrum för suicidforskning och prevention (NASP). För att mäta ångest användes Generalized Anxiety Disorder 7-item scale (GAD-7). Självkänsla mättes med Rosenberg Self-Esteem Scale (RSES). Resultatet visade på små effekter men indikerar att det finns ett samband mellan flickornas ångest och tid på sociala medier, och att drygt hälften (51%) av sambandet kan förklaras genom att tid på sociala medier indirekt påverkade deras självkänsla negativt (β = 0,13; p < 0,001). Vidare antydde resultatet att flickor, vars självkänsla påverkades av sociala medier, ökade sin ångest med 1,16 GAD-poäng för varje extra 2,54 timmar på sociala medier, i kontrast till en ökning av 0,56 GAD-poäng hos flickorna med mer stabil självkänsla. Genom att få en ökad förståelse för det eventuella sambandet mellan flickors upplevda ångest och användning av sociala medier kan preventiva åtgärder, som exempelvis stärker deras självkänsla, utvecklas som ett led i att minska potentiella skadeverkningar av sociala medier.

Composite International Diagnostic Interview screening scales for DSM-IV anxiety and mood disorders

Kessler, Ronald C., Calabrese, Joseph R., Farley, P. A., Gruber, Michael J., Jewell, Mark A., Katon, Wayne, Keck Jr., Paul E., Nierenberg, Andrew A., Sampson, Nancy A., Shear, M. K., Shillington, Alicia C., Stein, Murray B., Thase, Michael Edward, Wittchen, Hans-Ulrich 26 November 2013 (has links) (PDF)
Background Lack of coordination between screening studies for common mental disorders in primary care and community epidemiological samples impedes progress in clinical epidemiology. Short screening scales based on the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI), the diagnostic interview used in community epidemiological surveys throughout the world, were developed to address this problem. Method Expert reviews and cognitive interviews generated CIDI screening scale (CIDI-SC) item pools for 30-day DSM-IV-TR major depressive episode (MDE), generalized anxiety disorder (GAD), panic disorder (PD) and bipolar disorder (BPD). These items were administered to 3058 unselected patients in 29 US primary care offices. Blinded SCID clinical reinterviews were administered to 206 of these patients, oversampling screened positives. Results Stepwise regression selected optimal screening items to predict clinical diagnoses. Excellent concordance [area under the receiver operating characteristic curve (AUC)] was found between continuous CIDI-SC and DSM-IV/SCID diagnoses of 30-day MDE (0.93), GAD (0.88), PD (0.90) and BPD (0.97), with only 9–38 questions needed to administer all scales. CIDI-SC versus SCID prevalence differences are insignificant at the optimal CIDI-SC diagnostic thresholds (χ2 1 = 0.0–2.9, p = 0.09–0.94). Individual-level diagnostic concordance at these thresholds is substantial (AUC 0.81–0.86, sensitivity 68.0–80.2%, specificity 90.1–98.8%). Likelihood ratio positive (LR+) exceeds 10 and LR− is 0.1 or less at informative thresholds for all diagnoses. Conclusions CIDI-SC operating characteristics are equivalent (MDE, GAD) or superior (PD, BPD) to those of the best alternative screening scales. CIDI-SC results can be compared directly to general population CIDI survey results or used to target and streamline second-stage CIDIs.
