Internet-based, culturally sensitive, problem-solving therapy for turkish migrants with depression: Randomized controlled trial

Background: Turkish migrants living in the Netherlands have a high prevalence of depressive disorders, but experience considerable obstacles to accessing professional help. Providing easily accessible Internet treatments may help to overcome these barriers. Objective: The aim of this study was to evaluate the effectiveness of a culturally sensitive, guided, self-help, problem-solving intervention through the Internet for reducing depressive symptoms in Turkish migrants. Methods: A two-armed randomized controlled trial was conducted. The primary outcome measure was the severity of depressive symptoms; secondary outcome measures were somatic symptoms, anxiety, quality of life, and satisfaction with the treatment. Participants were assessed online at baseline, posttest (6 weeks after baseline), and 4 months after baseline. Posttest results were analyzed on the intention-to-treat sample. Missing values were estimated by means of multiple imputation. Differences in clinical outcome between groups were analyzed with a t test. Cohen's d was used to determine the between-groups effect size at posttreatment and follow-up. Results: Turkish adults (N=96) with depressive symptoms were randomized to the experimental group (n=49) or to a waitlist control group (n=47). High attrition rates were found among the 96 participants of which 42% (40/96) did not complete the posttest (6 weeks) and 62% (59/96) participants did not complete the follow-up assessment at 4 months. No significant difference between the experimental group and the control group was found for depression at posttest. Recovery occurred significantly more often in the experimental group (33%, 16/49) than in the control group (9%, 4/47) at posttest (P=.02). Because of the high attrition rate, a completers-only analysis was conducted at follow-up. The experimental group showed significant improvement in depression compared to the control group both at posttest (P=.01) and follow-up (P=.01). Conclusions: The results of this study did not show a significant effect on the reduction of depressive symptoms. However, the effect size at posttest was high, which might be an indicator of the possible effectiveness of the intervention when assessed in a larger sample and robust trial. Future research should replicate our study with adequately powered samples. © Burçin Ünlü Ince, Pim Cuijpers, Edith van 't Hof, Wouter van Ballegooijen, Helen Christensen, Heleen Riper

Guided self-help on the internet for turkish migrants with depression: the design of a randomized controlled trial

Background The Turkish population living in the Netherlands has a high prevalence of psychological complaints and has a high threshold for seeking professional help for these problems. Seeking help through the Internet can overcome these barriers. This project aims to evaluate the effectiveness of a guided self-help problem-solving intervention for depressed Turkish migrants that is culturally adapted and web-based. Methods This study is a randomized controlled trial with two arms: an experimental condition group and a wait list control group. The experimental condition obtains direct access to the guided web-based self-help intervention, which is based on Problem Solving Treatment (PST) and takes 6 weeks to complete. Turkish adults with mild to moderate depressive symptoms will be recruited from the general population and the participants can choose between a Turkish and a Dutch version. The primary outcome measure is the reduction of depressive symptoms, the secondary outcome measures are somatic symptoms, anxiety, acculturation, quality of life and satisfaction. Participants are assessed at baseline, post-test (6 weeks), and 4 months after baseline. Analysis will be conducted on the intention-to-treat sample. Discussion This study evaluates the effectiveness of a guided problem-solving intervention for Turkish adults living in the Netherlands that is culturally adapted and web-based

Working with pain : sustainable work participation of workers with chronic nonspecific musculoskeletal pain

Dit proefschrift is een van de eerste studies specifiek gericht op mensen die blijven werken met chronische pijn aan het bewegingsapparaat. Unieke kennis over duurzame arbeidsparticipatie van werknemers met chronische pijn werd vergaard. Doel van dit promotieonderzoek was meer inzicht te krijgen in de groep mensen die werkt met pijn en te achterhalen hoe zij in staat zijn ondanks hun klachten te blijven werken. In het proefschrift staan kenmerken en determinanten beschreven van werknemers die doorwerken met chronische pijn, waardoor een completer beeld is ontstaan van arbeidsparticipatie bij mensen met chronische pijn aan het bewegingsapparaat. Uit de vergelijking van mensen die doorwerken ondanks chronische pijn en mensen met arbeidsverzuim die in revalidatiebehandeling komen met chronische pijn blijkt dat deze groepen op diverse factoren significant verschillen. In het onderzoek werd onder andere aangetoond dat de motivatie voor werk, zelfmanagementvaardigheden en het belang dat wordt toegekend aan pijn, belangrijke factoren zijn die werken met chronische pijn faciliteren. Chronische pijn op zichzelf is vaak niet de reden voor arbeidsverzuim, maar meestal spelen persoonlijke- en omgevingsfactoren daarin een beslissende rol. Deze factoren kunnen dienen als aangrijpingspunt voor het verhogen van duurzame inzetbaarheid en preventie van arbeidsverzuim van mensen met chronische pijn aan het bewegingsapparaat. De effectieve manier waarop deelnemende werknemers in het onderzoek met hun pijn omgingen en productief bleven, kan anderen inspireren aan het werk te blijven. Daarnaast biedt het onderzoek een nieuw referentiekader voor de bedrijfs-, verzekerings-, en revalidatiegeneeskunde. This thesis was one of the first studies that focused specifically on people who continued work with chronic nonspecific musculoskeletal pain (CMP), and collected (identified) unique data concerning sustainable work participation of workers with CMP. It provides a large range of characteristics of workers with CMP who continued work despite pain, which has added to our understanding of sustainable work participation in people suffering from CMP. Comparison of workers who continued work with CMP with sick listed workers with CMP admitted for rehabilitation revealed that these groups differ significantly on several factors. In this thesis, evidence was found that the workers’ motivation to work, self-management skills, and the attributed importance of pain on their (working) lives are important factors to manage staying at work with CMP. It is recommended to be aware of the fact that CMP standing on itself is often not the reason for sick leave and disability, but regularly personal and environmental factors play an additional decisive role. Because these factors can be influenced, they offer opportunity to promote staying at work. In the process of guiding workers back to work, the results of the project ‘Working with pain’ may be used. The findings of this thesis potentially contribute to promotion of sustained work participation and prevention of sick-leave in workers with CMP. The effective way workers in this project coped with CMP and remained productive, may inspire others in their efforts to stay work. Finally, this thesis offers a new reference for rehabilitation-, occupational-,and insurance medicine.

Defining benzodiazepine dependence: The confusion persists

Contains fulltext : 22415.pdf (publisher's version ) (Open Access)Little consensus exists on the risk of benzodiazepine (BZD) dependence. We investigated how often BZD dependence and related concepts have been defined in the literature on BZD effects in humans. In addition, the definitions of BZD dependence were compared in order to assess the similarity of contents. From a total of 250 papers (published between 1988 and 1991) 51 provided 126 dependence-related definitions. Six studies referred to the DSM definitions and one to the WHO definition. The obsolete concept of addiction was frequently defined (n=13), with little consensus about its meaning. Psychological and physical dependence were defined fairly often (n=29), also with low levels of consensus. We conclude that the discussion on the risk of BZD dependence would be well-served by attempting to improve consensus first. This may lead to more meaningful data on the incidence, prevalence and relevant co-factors of BZD dependence. An outline for criteria for benzodiazepine dependence is presented

Tryptophan depletion affects the autonomic stress response in generalized social anxiety disorder

in generalized social anxiety disorder (gSAD), serotonergic dysfunctions are found, as well as abnormalities of the autonomic nervous system (ANS) in basal conditions and of the hypothalamic pituitary adrenal (HPA) axis in response to psychological challenges. These findings raise the question whether these phenomena are interrelated. Therefore we designed a study in which two groups with nine pair wise age and gender matched gSAD patients (total of 10 men and 8 women), who were successfully treated with a selective serotonin reuptake inhibitor (SSRI), underwent a tryptophan depletion challenge (TD) or a placebo condition. ATD procedure temporarily decreases serotonergic neurotransmission. In order to activate the stress system the TD/placebo challenge was combined with a public speaking task. We assessed ANS responses, as measured with the promising new marker salivary alpha-amylase (sAA), and HPA-axis responses, as measured with salivary cortisol. The most important result was that the TD group showed a significant larger sAA response to the public speaking task as compared to the placebo group, reflecting hyperresponsivity of the ANS in this group, whereas no differences were seen in cortisol responses. This suggests that in gSAD there is a vulnerability of the ANS more than the HPA-axis. (C) 2009 Elsevier Ltd. All rights reserved
