Internet Cognitive Behavioral Therapy With or Without Face-to-Face Psychotherapy: A 12-Weeks Clinical Trial of Patients With Depression.

Depressive disorders are a curable, global health problem. However, most patients remain untreated, and more and more patients use internet-based interventions, but it is unclear whether it is beneficial for ongoing face-to-face psychotherapy. Thus, we compared the outcome of internet cognitive behavioral therapy (ICBT) with (ICBT+) or without (ICBT) additional face-to-face outpatient psychotherapy in adult patients with moderate to severe depressive disorder. For this longitudinal interventional clinical trial (NCT02112266), 168 of 252 online recruited adults with depressive symptoms received ICBT+ (n = 96) or ICBT (n = 72). Demographics (sex, age, age at first depressive episode, years of education, duration of depressive symptoms) were assessed and compared between groups. All patients underwent ICBT for 12 weeks. Quality of life (QoL) and severity of depressive symptoms were assessed within each group at three time points [baseline (T0), postinterventional after ICBT at 12 weeks (T1), and for follow-up at 6 months (T2)] using the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF) global score to assess QoL as primary and the Beck Depression Inventory (BDI-II) to assess self-rated depressive symptoms as secondary outcome variables, respectively. Differences were assessed between groups using t test and over time using repeated-measures analysis of variance. Data of intention-to-treat analysis are given as mean ± SD. Group differences were assumed at p < 0.05. Partial η2 is given as effect size. Demographic data, QoL, and depressive symptoms did not differ between groups (ICBT+/ICBT) at baseline (T0). Patients of both groups suffered from moderate to severe depressive disorders and gained improved QoL scores (WHOQOL-BREF-global: p < 0.001, η2 = 0.16), as well as experienced decreased depressive symptoms (BDI-II: p < 0.001, η2 = 0.2) after 12 weeks of ICBT compared to baseline. Patients without additional face-to-face outpatient psychotherapy lost QoL-albeit not significant-and had increased depressive symptoms (BDI: p = 0.02, η2 = 0.04) at 6 months' follow-up. Thus, ICBT is suitable for psychiatric treatment, although additional face-to-face outpatient psychotherapy helps stabilizing long-term outcome.

Trichotillomania: the impact of treatment history on the outcome of an Internet-based intervention.

BACKGROUND: Many patients suffering from trichotillomania (TTM) have never undergone treatment. Without treatment, TTM often presents with a chronic course. Characteristics of TTM individuals who have never been treated (untreated) remain largely unknown. Whether treatment history impacts Internet-based interventions has not yet been investigated. We aimed to answer whether Internet-based interventions can reach untreated individuals and whether treatment history is associated with certain characteristics and impacts on the outcome of an Internet-based intervention. METHODS: We provided Internet-based interventions. Subjects were characterized at three time points using the Massachusetts General Hospital Hairpulling Scale, Hamilton Depression Rating Scale, and the World Health Organization Quality of Life questionnaire. RESULTS: Of 105 individuals, 34 were untreated. Health-related quality of life (HRQoL) was markedly impaired in untreated and treated individuals. Symptom severity did not differ between untreated and treated individuals. Nontreatment was associated with fewer depressive symptoms (P=0.002). Treatment history demonstrated no impact on the outcome of Internet-based interventions. CONCLUSION: Results demonstrate that Internet-based interventions can reach untreated TTM individuals. They show that untreated individuals benefit as much as treated individuals from such interventions. Future Internet-based interventions should focus on how to best reach/support untreated individuals with TTM. Additionally, future studies may examine whether Internet-based interventions can reach and help untreated individuals suffering from other psychiatric disorders.

E-mail support as an adjunct to cognitive-behavioral group therapy for social anxiety disorder: Impact on dropout and outcome.

The present study evaluates the impact of semi-individualized e-mail support as an adjunct to cognitive behavioral group therapy (CBGT) for social anxiety disorder (SAD) on dropout and outcome. The effectiveness of additional semi-individualized e-mail support was evaluated for the whole sample and for a subsample of patients at risk of dropping out of therapy. A total of 91 patients with SAD were allocated either to the intervention condition (CBGT with e-mail support), or to the control condition (CBGT without e-mail support). Anxiety symptoms, depression, global symptomatology and life satisfaction were assessed at pretreatment, post-treatment and follow-up (3, 6 and 12 months). From pre-treatment to post-treatment, both groups improved significantly on all symptom measures. Therapy gains were maintained at the 1-year follow-up. Subsample analyses showed that CBGT+e-mail was more effective than CGBT alone in reducing symptom severity among patients missing at least two therapy sessions. Additionally, in this subgroup, those receiving additional e-mail support showed a tendency towards lower dropout rates. Based on the results of this study, semi-individualized e-mail support between sessions seems to enhance the effectiveness of CBGT for SAD patients at risk of dropping out of treatment and should be considered as an additional tool in clinical practice.

Which tinnitus-related characteristics affect current health-related quality of life and depression? A cross-sectional cohort study.

Tinnitus is sometimes associated with lower health-related quality of life (HRQoL) and depressive symptoms. However, only limited evidence exists identifying which tinnitus characteristics are responsible for these associations. The aim of this cross-sectional study was to assess associations between tinnitus, HRQoL, depressive symptoms, subjective tinnitus loudness and audiometrically assessed tinnitus characteristics (e.g., hearing threshold). Two hundred and eight outpatients reporting tinnitus completed questionnaires on tinnitus (Tinnitus Handicap Inventory, THI), HRQoL (World-Health-Organisation Quality of Life Short Form Survey, WHOQOL-BREF), and depressive symptoms (Beck Depression Inventory, BDI), and underwent audiometry. Patients with higher THI scores exhibited significantly lower HRQoL, and higher depression scores. THI total-score, THI subscales, and subjective tinnitus loudness explained significant variance of WHOQOL-BREF and BDI. Audiometrically measured features were not associated with WHOQOL-BREF or BDI. Overall, we confirmed findings that different features of tinnitus are associated with HRQoL and depressive symptoms but not with audiometrically assessed tinnitus characteristics. Consequently, physicians should evaluate THI total score, its sub-scores, and subjective tinnitus loudness to reliably and quickly identify patients who potentially suffer from depressive symptoms or significantly lower HRQoL. Supporting these patients early might help to prevent the development of reactive depressive symptoms and impairment of HRQoL.

Affective regulation in trichotillomania before and after self-help interventions.

OBJECTIVE: Trichotillomania (TTM) is characterized by recurrent hair-pulling behaviours that cause significant distress. Deficits in affective regulation have been reported in individuals with TTM. We aimed to investigate temporal stability of affective regulation in TTM individuals. METHODS: Eighty-one TTM individuals underwent an online intervention. Affective Regulation Scale (ARS), Massachusetts General Hospital Hair-Pulling Scale (MGH-HPS), and Beck Depression Inventory (BDI) scores were obtained at baseline, post-treatment (4 weeks), and follow-up (6 months). We examined the effect of phenotypes including hair-pulling severity and depressive symptoms on absolute and relative stability of affective regulation over time, using multiple linear and hierarchical regression analyses. RESULTS: The ARS total-score from the present TTM sample was significantly lower than the score from non-hair pullers (p < 0.001). ARS total-scores inversely correlated with the MGH-HPS total-scores at baseline (p = 0.001) and post-treatment (p = 0.02), and with BDI total-scores at all time-points (p < 0.001). Although ARS total-scores significantly increased, all ARS sub-scores, except guilt sub-scores, did not change over time, indicating absolute stability. Baseline ARS total-, and sub-scores (except tension) were found to predict their ARS follow-up scores (all p < 0.01), confirming relative stability (i.e., the extent to which the inter-individual differences remained the same over time). The relative stability of ARS total-scores and all but two sub-scores (irritability and guilt) were independent from BDI baseline scores. CONCLUSIONS: Individuals with TTM reported deficits in affective regulation that demonstrated mostly high relative stability and partly absolute stability. Therefore, targeting to improve affective regulation in individuals with TTM during therapy is warranted.

Internet-based self-help for trichotillomania: a randomized controlled study comparing decoupling and progressive muscle relaxation.

BACKGROUND: Trichotillomania (TTM) is characterized by recurrent hair-pulling that results in substantial hair loss. A previous pilot study demonstrated that the online self-help intervention 'decoupling' (DC) might be effective at reducing hair-pulling symptoms, with a stronger effect than progressive muscle relaxation (PMR). We aimed to extend these findings using a more robust randomized clinical trial design, including diagnostic interviews by phone, a 6-month follow-up and e-mail support. METHODS: One hundred five adults with TTM were recruited online and randomly allocated to either DC (n = 55) or PMR (n = 50). The intervention lasted 4 weeks, with severity of TTM assessed at 3 time points (before intervention, immediately after intervention and at the 6-month follow-up) using the Massachusetts General Hospital Hair-Pulling Scale (MGH-HPS). Both intention-to-treat and completer analyses were conducted. RESULTS: Intention-to-treat analysis demonstrated highly significant and comparable symptom reductions (MGH-HPS) in both the DC and PMR groups (p < 0.001, partial x03B7;2 = 0.31) that persisted through 6 months of follow-up. Participants' subjective appraisals favoured DC in some areas (e.g. greater satisfaction with DC than PMR). Completer analyses demonstrated the same pattern as the intention-to-treat analyses. CONCLUSIONS: Despite subjective appraisals in favour of DC, symptom reduction was comparable in the two groups. While the results suggest that even short Internet-based interventions like DC and PMR potentially help individuals with TTM, a partial effect of unspecific factors, like regression towards the mean, cannot be ruled out. Therefore, longitudinal studies with non-treated controls are warranted.

Neuroimaging in social anxiety disorder­a meta-analytic review resulting in a new neurofunctional model.

Social anxiety disorder (SAD) is one of the most frequent anxiety disorders. The landmark meta-analysis of functional neuroimaging studies by Etkin and Wager (2007) revealed primarily the typical fear circuit as overactive in SAD. Since then, new methodological developments such as functional connectivity and more standardized structural analyses of grey and white matter have been developed. We provide a comprehensive update and a meta-analysis of neuroimaging studies in SAD since 2007 and present a new model of the neurobiology of SAD. We confirmed the hyperactivation of the fear circuit (amygdala, insula, anterior cingulate and prefrontal cortex) in SAD. In addition, task-related functional studies revealed hyperactivation of medial parietal and occipital regions (posterior cingulate, precuneus, cuneus) in SAD and a reduced connectivity between parietal and limbic and executive network regions. Based on the result of this meta-analysis and review, we present an updated model of SAD adopting a network-based perspective. The disconnection of the medial parietal hub in SAD extends current frameworks for future research in anxiety disorders.

Factors associated with non-treatment or delayed treatment seeking in OCD sufferers: a review of the literature.

Obsessive-compulsive disorder (OCD) is a disabling disorder that can be successfully treated. However, a high percentage of sufferers neither ask for nor receive treatment for their symptoms, or they delay seeking treatment. The factors underlying the treatment-seeking behaviour of OCD patients are still not clear. This review includes 12 studies published before April 2014 that analyse the possible variables related to the delayed help-seeking behaviour of OCD patients. Studies showed that individuals who asked for help were more impaired and reported poorer quality of life. Help-seeking behaviour was associated with greater insight, severity, specific obsessive-compulsive symptoms, such as aggressive and other unpleasant obsessions, and comorbidity. Common barriers to seeking treatment were shame about the symptoms or about asking for treatment, not knowing where to find help, or inconveniences associated with treatment. Inconsistencies among the reviewed studies highlight the need to further evaluate the variables that keep OCD patients from seeking help. The review highlights the need for educational campaigns designed to detect underdiagnosed OCD individuals and improve access to mental health services, which could shorten delays in seeking treatment and, therefore, reduce the personal and financial costs of OCD. Guidelines for educational programs and future lines of research are discussed.

[Insomnia in the general practitioner's office: from diagnosis to initial interventions]. / Insomnie in der Hausarztpraxis: von der Diagnostik zu ersten Interventionen.

Insomnia is the most frequent type of sleeping disorder and - following pain - the second most common symptom reported in the general practitioner's office. The prevalence of insomnia increases with age. Untreated, insomnia is regarded as risk factor for other comorbid somatic and mental disorders. Therefore, it is important to make a thorough diagnostic and differential diagnostic assessment. Particularly interventions aiming at improving sleep hygiene and therapy using sleep restriction can help alleviate insomnia. Pharmacologically, herbal drugs and antidepressants with sleep inducing effects can be used, for short-term treatment also benzodiazepine/gaba-ergic agonists.

Parmi les troubles du sommeil, l'insomnie est considérée comme la forme la plus commune et représente ­ après la douleur ­ le problème le plus fréquent dans le cabinet du médecin généraliste. La prévalence de l'insomnie augmente avec l'âge. Une insomnie non traitée représente un facteur de risque pour le développement d'une maladie somatique ou mentale. Un diagnostic différentiel et détaillé est donc essentiel. La discussion de mesures d'hygiène du sommeil et la restriction du sommeil dans le contexte d'une thérapie comportementale et cognitive sont des techniques efficaces pour améliorer la qualité du sommeil. Au niveau pharmacologique il est possible de prescrire des médicaments à base de plantes, des antidépresseurs ou, à court terme, des benzodiazépines.

California Psychotherapy Alliance Scale (CALPAS): psychometric properties of the German version for group and individual therapy patients.

BACKGROUND: Valid and internationally used instruments measuring therapeutic alliance are fundamental for psychotherapy research and practice. The main goal of this study was to validate a German version of the California Psychotherapy Alliance Scale (CALPAS) for the individual and the group therapy setting. METHODS: A total of 203 patients undergoing individual or group therapy filled out the CALPAS right after a therapy session. To test convergent and discriminant validity, a subsample of group therapy patients were handed out the Group Climate Questionnaire (GCQ) and a short form of the Symptom-Checklist (SCL-K-9). RESULTS AND CONCLUSION: The German version of the CALPAS showed good psychometric properties. Further, therapeutic alliance was found to be stronger in the individual than in the group context, suggesting a less central (or different) role played by group therapists. Clinical implications and possible focus of future research are discussed.

Increased cortical thickness in a frontoparietal network in social anxiety disorder.

Social anxiety disorder (SAD) is the second leading anxiety disorder. On the functional neurobiological level, specific brain regions involved in the processing of anxiety-laden stimuli and in emotion regulation have been shown to be hyperactive and hyper-responsive in SAD such as amygdala, insula and orbito- and prefrontal cortex. On the level of brain structure, prior studies on anatomical differences in SAD resulted in mixed and partially contradictory findings. Based on previous functional and anatomical models of SAD, this study examined cortical thickness in structural magnetic resonance imaging data of 46 patients with SAD without comorbidities (except for depressed episode in one patient) compared with 46 matched healthy controls in a region of interest-analysis and in whole-brain. In a theory-driven ROI-analysis, cortical thickness was increased in SAD in left insula, right anterior cingulate and right temporal pole. Furthermore, the whole-brain analysis revealed increased thickness in right dorsolateral prefrontal and right parietal cortex. This study detected no regions of decreased cortical thickness or brain volume in SAD. From the perspective of brain networks, these findings are in line with prior functional differences in salience networks and frontoparietal networks associated with executive-controlling and attentional functions.

[Obsessive compulsive disorder--intrusive thoughts, impulses and repetitive behaviours as an expression of a significant disease]. / Zwangsstörungen--wenn wiederholte gedanken, impulse und handlungen ausdruck einer erkrankung sind.

Obsessive-compulsive disorder (OCD) is common and associated with marked impairment and reduced quality of life. In the general practitioner's office as well as in the specialist's consultation, patients with OCD usually present intrusive thoughts (obsessions) and repetitive behaviours (compulsions). OCD sufferers generally recognize their obsessions and compulsions as irrational. Without treatment, OCD often takes a chronic course. Some basic aspects can help to identify patients suffering from OCD earlier and to initiate sufficient therapy. With evidence-based treatment with cognitive-behavioral therapy and adequate psychopharmacotherapy, many patients can achieve complete symptom remission. Initial treatment can be initiated in the general practitioner's office.

Le trouble obsessionnel-compulsif est une maladie mentale qui affecte la qualité de vie d'une manière significative. Dans le cabinet du médecin généraliste, mais aussi chez le spécialiste, les patientes souffrant de troubles obsessionnels-compulsifs décrivent souvent des pensées intrusives inhabituelles et des comportements répétitifs. Bien que les pensées obsessionnelles et les compulsions sont reconnues par les patients comme insensées, elles continuent à se manifester. Sans traitement, le trouble obsessionnel-compulsif devient souvent chronique. Des connaissances de base peuvent déjà aider les médecins à reconnaître le plus tôt possible les patients souffrant de troubles obsessionnels et à proposer un traitement approprié. Avec thérapie cognitivo-comportementale, qui peut être combinée avec un traitement pharmacologique, on obtient souvent une réduction significative, même complète des symptômes. Bien que ce traitement doive être effectué par des psychothérapeutes qualifiés, des premières mesures thérapeutiques peuvent déjà être utilisées par les médecins généralistes.

Evidence of frontotemporal structural hypoconnectivity in social anxiety disorder: A quantitative fiber tractography study.

Investigation of the brain's white matter fiber tracts in social anxiety disorder (SAD) may provide insight into the underlying pathophysiology. Because models of pathological anxiety posit altered frontolimbic interactions, the uncinate fasciculus (UF) connecting (orbito-) frontal and temporal areas including the amygdala is of particular interest. Microstructural alterations in parts of the UF have been reported previously, whereas examination of the UF as discrete fiber tract with regard to more large-scale properties is still lacking. Diffusion tensor imaging was applied in 25 patients with generalized SAD and 25 healthy control subjects matched by age and gender. By means of fiber tractography, the UF was reconstructed for each participant. The inferior fronto-occipital fasciculus (IFOF), originating from the frontal cortex similarly to the UF, was additionally included as control tract. Volume and fractional anisotropy (FA) were compared between the groups for both tracts. Volume of left and right UF was reduced in patients with SAD, reaching statistical significance for the left UF. Bilateral IFOF volume was not different between groups. A similar pattern was observed for FA. Reduced volume of the left UF in SAD fits well into pathophysiological models of anxiety, as it suggests deficient structural connectivity between higher-level control areas in the orbitofrontal cortex and more basal limbic areas like the amygdala. The results point to a specific role of the left UF with regard to altered white matter volume in SAD. However, results should be replicated and functional correlates of altered UF volume be determined in future studies.

General emotion processing in social anxiety disorder: neural issues of cognitive control.

Anxiety disorders are characterized by deficient emotion regulation prior to and in anxiety-evoking situations. Patients with social anxiety disorder (SAD) have increased brain activation also during the anticipation and perception of non-specific emotional stimuli pointing to biased general emotion processing. In the current study we addressed the neural correlates of emotion regulation by cognitive control during the anticipation and perception of non-specific emotional stimuli in patients with SAD. Thirty-two patients with SAD underwent functional magnetic resonance imaging during the announced anticipation and perception of emotional stimuli. Half of them were trained and instructed to apply reality-checking as a control strategy, the others anticipated and perceived the stimuli. Reality checking significantly (p<0.01) reduced activity in insular, amygdalar and medial thalamic areas during the anticipation and perception of negative emotional stimuli. The medial prefrontal cortex was comparably active in both groups (p>0.50). The results suggest that cognitive control in patients with SAD influences emotion processing structures, supporting the usefulness of emotion regulation training in the psychotherapy of SAD. In contrast to studies in healthy subjects, cognitive control was not associated with increased activation of prefrontal regions in SAD. This points to possibly disturbed general emotion regulating circuits in SAD.

White matter alterations in social anxiety disorder.

White matter architecture in patients with social anxiety disorder (SAD) has rarely been investigated, but may yield insights with respect to altered structural brain connectivity. Initial evidence points to alterations in the uncinate fasciculus (UF). We applied diffusion tensor imaging in 25 patients with SAD and 25 matched healthy subjects. Whole-brain fractional anisotropy (FA) maps were used for group comparison and voxel-wise correlation with psychometric and clinical measures. Additionally, a region-of-interest analysis of the UF was performed. Patients with SAD had reduced FA compared to healthy subjects in or near the left UF and the left superior longitudinal fasciculus. There were no regions with increased FA in SAD. In the region-of-interest analysis, a negative correlation between FA and trait anxiety was identified in the left and right UF in patients, but not in healthy subjects. No correlations with social anxiety scores were observed. The present study partially confirms previous results pointing to frontal WM alterations in or near the UF in patients with SAD. SAD-specific dimensional associations of FA with trait anxiety might reflect general pathological and/or compensatory mechanisms as a function of symptom severity in patients. Future studies should disentangle in which way the identified WM alterations match functional alterations.

Neural correlates of altered general emotion processing in social anxiety disorder.

Specific anxiety disorders are characterized by altered emotion processing of phobia-specific stimuli at the neurobiological level. Recent work has concentrated on specific anxiety-provoking stimuli; focusing on arousal- or fear-related brain areas such as the amygdala. We analyzed brain activation during the cued anticipation of unpleasant or uncertain emotional stimuli as a means of modeling an unspecific anxiety-laden situation. Sixteen patients with social anxiety disorder (SAD) and eighteen healthy control subjects completed a task during functional magnetic resonance imaging involving the anticipation of cued visual stimuli with prior known emotional valence (positive, negative, and neutral) or prior unknown/ambiguous emotional content. The anticipated stimuli had no social phobia specific content. During the anticipation of emotional stimuli of prior known negative and prior ambiguous emotional valence, brain activity in patients with SAD was increased in the upper midbrain/dorsal thalamus, the amygdala, and in temporo-occipital and parietal regions as compared to control subjects. Activity was decreased in SAD in left orbitofrontal cortex. Activations in the amygdala and in occipital regions correlated with trait anxiety and social anxiety measures. In conclusion, SAD was associated with enhanced activation in brain regions involved in emotional arousal as well as in attention and perception processing during the anticipation of non-specific, general emotional stimuli. Hence, our results suggest that patients with SAD not only have an altered processing of specific feared stimuli, but also a more generally disturbed emotion processing in basic neural pathways. These findings have implications for diagnostic models and the treatment of SAD.

Finger length ratio (2D:4D) in adults with gender identity disorder.

From early childhood, gender identity and the 2nd to 4th finger length ratio (2D:4D) are discriminative characteristics between sexes. Both the human brain and 2D:4D may be influenced by prenatal testosterone levels. This calls for an examination of 2D:4D in patients with gender identity disorder (GID) to study the possible influence of prenatal testosterone on gender identity. Until now, the only study carried out on this issue suggests lower prenatal testosterone levels in right-handed male-to-female GID patients (MtF). We compared 2D:4D of 56 GID patients (39 MtF; 17 female-to-male GID patients, FtM) with data from a control sample of 176 men and 190 women. Bivariate group comparisons showed that right hand 2D:4D in MtF was significantly higher (feminized) than in male controls, but similar to female controls. The comparison of 2D:4D ratios of biological women revealed significantly higher (feminized) values for right hands of right handed FtM. Analysis of variance confirmed significant effects for sex and for gender identity on 2D:4D ratios but not for sexual orientation or for the interaction among variables. Our results indirectly point to the possibility of a weak influence of reduced prenatal testosterone as an etiological factor in the multifactorially influenced development of MtF GID. The development of FtM GID seems even more unlikely to be notably influenced by prenatal testosterone.

Does prior psychotherapy experience affect the course of cognitive-behavioural group therapy for social anxiety disorder?

OBJECTIVE: To examine whether and how different patterns of psychotherapy history (no prior therapy, successful therapy experience, and unsuccessful therapy experience) affect the outcome of future treatment among patients undergoing cognitive-behavioural group therapy for social anxiety disorder. METHOD: Fifty-seven patients with varying histories of psychotherapy participating in cognitive-behavioural group treatment for social anxiety disorder were included in the study. Symptom severity (including anxiety, depression, self-efficacy, and global symptom severity) was assessed at pre- and posttreatment. A therapist-rated measure of patient therapy engagement was included as a process variable. RESULTS: First-time therapy patients showed more favourable pretreatment variables and achieved greater benefit from group therapy. Among patients with unsuccessful therapy experience, substantial gains were attained by those who were able to actively engage in the therapy process. Patients rating previous therapies as successful could benefit the least and tended to stagnate. Possible explanations for group differences and clinical implications are discussed. CONCLUSIONS: Prior psychotherapy experience affects the course of cognitive-behavioural group therapy in patients with social phobias. While patients with negative therapy experience may need extensive support in being and remaining actively engaged, those rating previous therapies as successful should be assessed very carefully and may benefit from a major focus on relational aspects.

Perceived responsibility for change as an outcome predictor in cognitive-behavioural group therapy.

PURPOSE: The study of control beliefs in psychotherapy research has been neglected in the past years. Based on the evidence that some patients do not benefit enough from therapy because of inadequate expectancies regarding the responsibility and the mechanisms of therapeutic change, assessing control beliefs specific to the psychotherapy context and linking them to therapy outcome can help highlighting this specific aspect and reactivating a neglected field of clinical research. METHOD: Using a new validated instrument (Questionnaire on Control Expectancies in Psychotherapy, TBK), this study investigated whether and how perceived responsibility for change predicts favourable response to group cognitive-behavioural therapy in a sample of 49 outpatients with social anxiety disorder (SAD). Patient engagement and therapy-related self-efficacy were assessed as possible process variables. RESULTS: Among therapy-related control beliefs, low powerful others expectancies (towards the therapist) were found to be the strongest predictor for clinical improvement at follow-up. At a process level, analyses of mediation showed that powerful others expectancies predicted therapy engagement, which then influenced the degree of clinical improvement on social anxiety levels and global symptoms. The association between therapy-specific internality and outcome was confirmed for social anxiety at follow-up and was partially mediated by therapy-related self-efficacy. CONCLUSIONS: Findings confirm that therapy-related control beliefs predict psychotherapy process (patient engagement and therapy-specific self-efficacy) and outcome in cognitive-behavioural group therapy for SAD. Implications for clinicians and for future research are discussed.

Body image and transsexualism.

BACKGROUND: To achieve a detailed view of the body image of transsexual patients, an assessment of perception, attitudes and experiences about one's own body is necessary. To date, research on the body image of transsexual patients has mostly covered body dissatisfaction with respect to body perception. SAMPLING AND METHODS: We investigated 23 preoperative (16 male-to-female and 7 female-to-male transsexual patients) and 22 postoperative (14 male-to-female and 8 female-to-male) transsexual patients using a validated psychological measure for body image variables. RESULTS: We found that preoperative transsexual patients were insecure and felt unattractive because of concerns about their body image. However, postoperative transsexual patients scored high on attractiveness and self-confidence. Furthermore, postoperative transsexual patients showed low scores for insecurity and concerns about their body. CONCLUSIONS: Our results indicate an improvement of body image concerns for transsexual patients following standards of care for gender identity disorder. Follow-up studies are recommended to confirm the assumed positive outcome of standards of care on body image.
