[Some Key Steps for App Design]. / Des repères pour la conception des apps ?

Objective To propose some key steps to facilitate the process of creating mental health smartphone applications (apps). Methods Brief presentation of the potential interest of apps and proposition of key steps for the creation of apps. The paper is based on a narrative review, a testimonial experience and some expert works. Results Apps have ubiquitous features that are particularly appealing for the mental health field. Potentially connected to multiple technologies, mobile and available at all times, they allow great design flexibility. In order to increase the chances of effectiveness and good dissemination of a given app, 9 principles could usefully guide the design of apps, in particular a good integration of end users around well-defined target objectives during the entire process of creating such tools. Conclusion The proposed key steps could facilitate the process of creating mental health apps.

Augmentation of Psychotherapy through Alternative Preconscious Priming: A Case Series Exploring Effects on Residual Symptoms.

The current paper describes a case series using a new strategy for facilitating change based on Augmentation of Psychotherapy through Alternative Preconscious Priming (APAP) (1) in the treatment of eight treatment-resistant patients suffering from social phobia or generalized anxiety disorder. The patients had previously only shown a partial response to cognitive behavioral therapy (CBT) despite good treatment adherence. The patients completed APAP using a computerized program, which consisted of three steps during which alternative, more functional thoughts and beliefs relevant to the idiosyncratic difficulties experienced by the patients were formulated. Subsequently, these formulations were recorded and mixed with masking relaxing music, which the patient listened to in a passive state twice daily for 20 min for a period of 8 weeks. This case series aimed to assess the effect and acceptability of APAP using quantitative and qualitative measures administered before, after, and 16 weeks' posttreatment. Results showed a reduction in dysfunctional idiosyncratic thoughts reported by most patients, as well as mild improvements in anxiety and important improvements in quality of life. APAP could be a valuable addition to CBT by facilitating or enhancing cognitive and symptom change. Further studies are needed to confirm these promising results.

[The changes in values and beliefs through the first 50 years of the department of Psychiatry at the University of Montreal]. / Le changement de nos valeurs et certitudes au long de ce demi-siècle.

This essay attempts to describe and discuss the major changes in values and fundamental beliefs related to clinical practice within the Département de psychiatrie de l'Université de Montréal since its creation fifty years ago.Being an essay, the methods include shared recollections, discussions with colleagues, especially between the co-authors, and the study of some documents related to the practice of psychiatry 40 to 50 years ago.Five major axes of change are proposed: 1- From psychoanalysis to brain diseases, 2- From "Can a non-physician practice psychoanalysis?" to "Can a psychiatrist still perform psychotherapy?" 3- From continuity of care to episodes of treatment, 4- From treatment first to repeated assessments of patients, 5- From love that can heal and repair to a taboo of love.Finally it is suggested that the increasing emphasis on psychopharmacology and on DSM classifications has contributed to a shift from attempts to understand the intimate nature of symptoms and suffering to a priority given to rather mechanical clinical assessments in search of "objective" criteria.

Venlafaxine versus applied relaxation for generalized anxiety disorder: a randomized controlled study on clinical and electrophysiological outcomes.

Some components of generalized anxiety disorder, such as physical symptoms, are thought to reflect autonomic nervous system arousal. This study primarily assessed the relationships between psychophysiological and clinical measures using venlafaxine extended release or applied relaxation, and secondarily, the impact of combination treatment in patients not remitting after 8 weeks. Fifty-eight patients were randomly assigned to 8 weeks of treatment with either venlafaxine or applied relaxation (Phase I). Non-remitted patients received combination treatment for an additional 8 weeks (Phase II). Assessments included the Hamilton Anxiety Scale (HAM-A), Beck Depression Inventory, Penn State Worry Questionnaire and the Stroop Color-Word Task coupled with electrophysiological measures (skin conductance and frontalis electromyography (EMG)). In Phase 1, a time effect was found for the clinical and skin conductance measures. Thirteen patients from each group were in remission. In Phase 2, seven additional patients remitted. Baseline psychophysiological measures were not associated with baseline clinical variables or with clinical outcomes. Independently of treatment allocation, a reduction in frontal EMG values at week 4 was significantly associated with a decrease in HAM-A scores at week 8. At week 4, responders from the applied relaxation group had lower electrophysiological activity than the venlafaxine group. Baseline psychophysiological measures were not linked with clinical measures at study inclusion or with treatment response. Frontal EMG response at week 4 is a possible predictor of treatment response. Treatment combination enhances treatment response after initial failure.

Psychotherapy Augmentation through Preconscious Priming.

OBJECTIVE: To test the hypothesis that repeated preconscious (masked) priming of personalized positive cognitions could augment cognitive change and facilitate achievement of patients' goals following a therapy. METHODS: Twenty social phobic patients (13 women) completed a 36-weeks study beginning by 12 weeks of group behavioral therapy. After the therapy, they received 6 weeks of preconscious priming and 6 weeks of a control procedure in a randomized cross-over design. The Priming condition involved listening twice daily with a passive attitude to a recording of individualized formulations of appropriate cognitions and attitudes masked by music. The Control condition involved listening to an indistinguishable recording where the formulations had been replaced by random numbers. Changes in social cognitions were measured by the Social Interaction Self Statements Test (SISST). RESULTS: Patients improved following therapy. The Priming procedure was associated with increased positive cognitions and decreased negative cognitions on the SISST while the Control procedure was not. The Priming procedure induced more cognitive change when applied immediately after the group therapy. CONCLUSION: An effect of priming was observed on social phobia related cognitions in the expected direction. This self administered addition to a therapy could be seen as an augmentation strategy.

Cognitive behavioral management of Tourette's syndrome and chronic tic disorder in medicated and unmedicated samples.

OBJECTIVE: Cognitive behavior therapy (CBT) and medication can be administered in combination in treating tic disorders but there are no studies evaluating the effectiveness of CBT with and without medication. The current study compares the efficacy of CBT in combination with medication and without medication. METHOD: CBT was administered in a consecutively referred sample of 76 people diagnosed either with Gilles de la Tourette Syndrome or chronic tic disorder. The sample was divided into a medicated and a non-medicated group. Twenty three were stabilized on medication and 53 were not receiving medication. Measures administered pre- and post-CBT in both groups included: main outcome measure of Tourette Syndrome Global Scale and measures of mood. RESULTS: Repeated measures analysis of variance on the initial sample revealed no difference between medicated and non-medicated groups in outcome. A further analysis comparing the 23 receiving medication with 23 not receiving medication matched on baseline clinical variables also yielded no significant group differences, either in treatment outcome on main tic outcome measures or on other clinically relevant questionnaires. DISCUSSION: CBT for tic disorders is an effective treatment administered either in combination with medication or alone.

Does the form or the amount of exposure make a difference in the cognitive-behavioral therapy treatment of social phobia?

Exposure is considered to be an essential ingredient of cognitive-behavioral therapy treatment of social phobia and of most anxiety disorders. To assess the impact of the amount of exposure on outcome, 30 social phobic patients were randomly allocated to 1 of 2 group treatments of 8 weekly sessions: Self-Focused Exposure Therapy which is based essentially on prolonged exposure to public speaking combined with positive feedback or a more standard cognitive and behavioral method encompassing psychoeducation, cognitive work, working through exposure hierarchies of feared situations for exposure within and outside the group. The results show that the 2 methods led to significant and equivalent symptomatic improvements which were maintained at 1-year follow-up. There was a more rapid and initially more pronounced decrease in negative cognitions with the Self-Focused Exposure Therapy, which included no formal cognitive work, than with the more standard approach in which approximately a third of the content was cognitive. In contrast, decrease in social avoidance was more persistent with standard cognitive-behavior therapy which involved less exposure. The results indicate that positive cognitive change can be achieved more rapidly with non cognitive methods while avoidance decreases more reliably with a standard approach rather than an approach with an exclusive focus on exposure.

Treatment of panic disorder with agoraphobia: randomized placebo-controlled trial of four psychosocial treatments combined with imipramine or placebo.

Few randomized controlled trials have included panic disorder patients with moderate to severe agoraphobia. Therefore, this population was studied using pharmacotherapy as well as psychotherapy. At the time of the study, imipramine was widely used as a pharmacological treatment. Also, current practice guidelines for patients with panic disorder find selective serotonin reuptake inhibitors and tricyclic antidepressants roughly comparable in terms of efficacy. Therefore, the main objective of this study is to compare four psychosocial treatments-cognitive and graded in vivo exposure treatments, graded in vivo exposure, cognitive treatment, and supportive therapy-to evaluate the benefits of combining cognitive therapy with exposure in vivo. These treatments were combined with imipramine or placebo for a total of eight experimental conditions. Participants presented moderate to severe agoraphobia. The method involved a randomized, double-blind, placebo-controlled trial with 137 participants who completed a 14-session protocol involving the treatments just mentioned. Measures were taken at baseline and posttreatment and at 3-, 6-, and 12-month follow-up. All treatment conditions were statistically and clinically effective in reducing self-reported panic-agoraphobia symptoms over the 1-year follow-up. No statistical differences were observed between imipramine and placebo conditions. This study found that all treatment modalities helped reduce panic and agoraphobic symptomatology over a 1-year follow-up period. These surprising results support the need to document the relations among the various components of an intervention. This would make it possible to assess the relative efficacy of the treatment components rather than of the intervention as a whole.

Cognitive-behaviour therapy and skilled motor performance in adults with chronic tic disorder.

The first aim of the present study was to compare performance of people with tic disorders (TD) and controls on executive function and a range of skilled motor tests requiring complex performance, guided movements, hand co-ordination, and fine control of steadiness. The second aim was to investigate the effect of cognitive behaviour therapy (CBT) on motor performance. A total of 55 patients with TD were recruited at baseline from participants in a behavioural management programme. A comparison group of 55 patients suffering from a variety of habit disorders (HD) involving complex manual movements, were matched on age and level of education to 34 non-psychiatric controls. Participants were evaluated pre- and post-treatment and post-waitlist with a neuropsychological evaluation focusing on executive function (Wisconsin Card Sorting Test, WCST) and skilled motor performance (Purdue Pegboard, Hole Steadiness Test, and the Groove Test). Results revealed WCST scores in the normal range, while motor performance differed significantly on the Purdue Pegboard Tests in both TD and HD as compared to the control group. Cognitive-behavioural treatment selectively improved motor performance in both clinical groups compared to waitlist control, and this improvement related to clinical outcome measures.

Swiss psychiatrists beliefs and attitudes about cannabis risks in psychiatric patients: ideologically determined or evidence-based?

The objective of this survey was to assess the beliefs of Swiss psychiatrists about the risks associated with cannabis, and to assess their prohibitive attitudes toward their patients. Eighty-two doctors agreed to fill-up the questionnaire. Cluster analysis retained a 3-cluster solution. Cluster 1: "Prohibitionists" believed that cannabis could induce and trigger all forms of psychiatric disorder, and showed a highly prohibitive attitude. Cluster 2: "Causalists" believed that schizophrenia, but not other psychiatric disorders, could be induced and triggered. Cluster 3: "Prudent liberals" did not believe that psychiatric disorders could be induced by cannabis, and were generally less prohibitive.

Cognitive behavioural therapy for weight gain associated with antipsychotic drugs.

BACKGROUND: Overweight and obesity are common concerns in individuals with severe mental disorders. In particular, antipsychotic drugs (AP) frequently induce weight gain. This phenomenon lacks current management and no previous controlled studies seem to use cognitive therapy to modify eating and weight-related cognitions. Moreover, none of these studies considered binge eating or eating and weight-related cognitions as possible outcomes. AIM: The main aim of this study is to assess the effectivity of cognitive and behavioural treatment (CBT) on eating and weight-related cognitions, binge eating symptomatology and weight loss in patients who reported weight gain during AP treatment. METHOD: A randomized controlled study (12-week CBT vs. Brief Nutritional Education) was carried out on 61 patients treated with an antipsychotic drug who reported weight gain following treatment. Binge eating symptomatology, eating and weight-related cognitions, as well as weight and body mass index were assessed before treatment, at 12 weeks and at 24 weeks. RESULTS: The CBT group showed some improvement with respect to binge eating symptomatology and weight-related cognitions, whereas the control group did not. Weight loss occurred more progressively and was greater in the CBT group at 24 weeks. CONCLUSION: The proposed CBT treatment is particularly interesting for patients suffering from weight gain associated with antipsychotic treatment.

Eating and weight related cognitions in people with Schizophrenia : a case control study.

BACKGROUND: Patients with antipsychotic-induced weight gain (WG) regularly report on unsuccessful dietary trials, which suggests strong biological weight gain drive that is extremely hard to overcome with thoughts, such that behaviour doesn't change despite some intent to change. The purpose of the present study was to assess cognitions specifically related to restrained eating in severely overweight patients with schizophrenia treated with antipsychotic drugs. METHODS: Forty outpatients with schizophrenia and 40 controls without psychiatric disability were included. Both groups were composed of one subgroup severely overweight (defined as a BMI > 28), and a comparison sample (BMI<28). The revised version of the Mizes Anorectic cognitive questionnaire (MAC-R) was used in this cross-sectional case-control study. RESULTS: Gender was significantly related to eating disorders cognition, women scoring higher than men. Patients with schizophrenia in general scored higher on the MAC-R total scale and on the MAC-R subscale 2, the latter score representing rigid weight regulation and fear of weight gain. When comparing the two groups of subjects with BMI < 28, it appeared that patients with schizophrenia also scored higher on MAC-R total scale, the subscales 2 and 3, the latter subscale 3, indicating altered self control and self-esteem. CONCLUSION: As is the case in weight gain of subjects without schizophrenia, the present results suggest that the cognitive distortions, as assessed by the MAC-R, may play an important role in weight gain also in patients with schizophrenia, and in weight gain associated with antipsychotic pharmacotherapy. Particular attention to these processes may help to improve the management of antipsychotic drugs induced weight gain.

Binge eating symptomatology in overweight and obese patients with schizophrenia: a case control study.

OBJECTIVE: The purpose of this study was to assess whether severe overweight schizophrenic treated patients differ from controls and from pairs in binge eating symptomatology. METHOD: Current body mass index (BMI) and the binge eating status were assessed cross-sectionally in 40 schizophrenic outpatients and 40 non-psychiatric controls. In each group half of the subjects were severe overweight (BMI > or = 28) or obese. RESULTS: Pearson Chi-square analysis shows a higher number of subjects with binge symptomatology in the group of patients with schizophrenia having BMI > or = 28 (Pearson Chi-square = 8.67, p = 0.034). Among subjects with BMI > or = 28, 60% of patients with schizophrenia and 30% of controls have binge eating symptomatology. CONCLUSION: This result may odds to the understanding of weight gain associated with antipsychotics and underscores the importance of assessing binge eating behaviour during treatment and prevention of obesity in this population.

Prevalence of substance use in a Swiss psychiatric hospital: interview reports and urine screening.

BACKGROUND: Co-morbid substance misuse is common in psychiatric disorders, has potentially severe adverse consequences and may be frequently undetected. AIMS: To measure the prevalence of substance use among patients admitted to a Swiss psychiatric hospital and to examine the potential utility of routine urine drug screening in this setting. METHOD: 266 inpatients were included. 238 patients completed the interview and 240 underwent a urine drug screening. RESULTS: Lifetime prevalence of substance use among psychiatric patients was very high for alcohol (98%; 95% CI: 96-100), benzodiazepines (86%; 95% CI: 82-91) and cannabis (53%; 95% CI: 47-60), but also for "hard drugs" like cocaine (25% ; 95% CI: 19-30) or opiates (20%; 95% CI: 15-25). Regular current use of alcohol (32%; 95% CI: 26-38) or cannabis (17%; 95% CI: 12-22) was the most frequent. Substance use was associated with male sex, younger age, unmarried status and nicotine smoking. Urine screening confirms reports from patients on recent use, and remained positive for cannabis during hospitalisation, but not for cocaine nor for opiates. CONCLUSION: Substance use is frequent among psychiatric patients. Systematic interviewing of patients about their substance use remains essential, and is usually confirmed by urine screening. Urine screening can be useful to provide specific answers about recent use.

Brain-behavior relations during motor processing in chronic tic and habit disorder.

OBJECTIVE: This study examined electrophysiological indices of preparation (readiness potential, RP) and execution (movement-associated potential, MAP) during automated and controlled reaction time (RT) in 13 chronic tic disorder, 17 habit disorder, and 14 control participants. BACKGROUND: Both tic and habit disorders are hypothesized to involve states of heightened activation, which could impede initiation and the control of complex motor actions. METHOD: The electrophysiological signal was recorded from 4 electrodes (Fz, C3, C4, Pz) during a fixed 4-second foreperiod reaction time task. RESULTS: During automated responses, controls showed a shorter RP peak onset, and during controlled responses a longer MAP peak onset, compared with both clinical groups. The controls were the only group who showed a consistent linear relationship between RP and RT. CONCLUSIONS: Patients with chronic tic as well as habit disorder may not modulate cortical activation optimally in planning and executing both automated and controlled responses.

Perceived coercion and need for hospitalization related to psychiatric admission.

Psychiatric hospitalization constitutes a moment of major stress to the point that occurrences of posttraumatic stress disorders have been described. Feelings of coercion are usual, whatever the legal status of admission. Patients may also consider afterwards that they needed hospitalization even if they refused it initially. A cross-sectional survey has been conducted among the inpatients of a Swiss psychiatric hospital to assess their subjective view of admission with emphasis on legal status, perceived coercion and need for hospitalization. Eighty-seven questionnaires were completed and analyzed. Results indicated that 74% of patients felt that they had been under pressure to be hospitalized, whether or not they were involuntarily admitted. Seventy percent felt their admission was necessary. More involuntary patients reported a subjective lack of improvement. Clinicians could decrease feelings of coercion of their patients while discussing need for hospitalization, legal status and subjective feeling of coercion as different dimensions. An argument is presented to favor positive pressure from social environment over legal involuntary commitment in many hospitalizations.

Anticonvulsant drugs in the treatment of substance withdrawal.

Although detoxification cannot, in itself, be considered a treatment for addiction, it is one of the most pivotal phases. In order to facilitate entry into recovery and/or rehabilitation programs, a detoxification treatment has to be experienced as easy and safe by the patient. In consideration of the many inconveniences related to standard withdrawal treatments, there is an interest in developing alternative pharmacological strategies. The main rationales for using anticonvulsants in substance-abuse patients are their lack of addiction potential, evidence support a role of kindling mechanisms in withdrawal syndromes and their efficacy in comorbid psychiatric disorders. The available data currently support the utilization of carbamazepine as a treatment for detoxification from benzodiazepines, alcohol and opiates, and as a useful agent to reduce cocaine consumption. The use of valproate is well corroborated for alcohol detoxification and it seems to be a promising treatment for the reduction of cocaine use; however, it has been found to be ineffective against benzodiazepine withdrawal symptoms. Some preliminary data suggest that lamotrigine could be useful in opiate and cocaine dependence. Gabapentin shows potential as a treatment for cocaine dependence, and some case reports have stimulated interest in this agent for alcohol and benzodiazepine detoxification. Due to its particular pharmacological profile, topiramate is one of the most interesting newer anticonvulsants. It has been found to be efficacious in opiate and possibly benzodiazepine detoxification and also has theoretical potential as a preventive therapy.

[A few unresolved and frequent questions concerning anxiety and anxiety disorders]. / Quelques questions fréquentes ou non résolues concernant l'anxiété et les troubles anxieux.

The field of anxiety disorders shows a considerable evolution in the last decades concerning the overall conceptualization of the disorders and concerning their treatment. However many questions remain open. For instance, what is the importance of anxiety disorders in terms of public health? What is their influence on other factors affecting populations' health, e.g. substance abuse, and especially smoking? Questions also remain concerning the underlying mechanisms, whether biological or psychological. For instance, is it possible to identify cognitive schemas leading to pathological anxiety? What are the physiological manifestations of the hypervigilance and hyperreactivity that are described clinically? Despite the successive classifications, some issues are unsettled concerning the delimitation of anxiety disorders. For instance, do obsessive-compulsive disorders belong to anxiety disorders or preferably to a different family of mental disorders constituting a spectrum of obsessive-compulsive disorders? Several practical issues remain open for clinicians: what is the importance of specific therapeutic factors in cognitive-behavioral therapies? Is there a psychoanalytical method and a psychopharmacological therapy specific to anxiety disorders? Concrete questions also deserve attention in relation with therapeutic modalities. Are group treatments superior to individual ones? What is the role of emotion in cognitive-behavioral treatment? Is it useful to associate self-regulation strategies like meditation? Do self-help organizations, that are numerous and helpful in that field, have a role concerning psychotherapy?

[How hypervigilance and hyperreactivity clinically described in anxiety expressed physiologically?]. / Comment s'expriment physiologiquement l'hypervigilance et l'hyperréactivité décrites cliniquement pour l'anxiété ?

Anxious people often show a particular attentional focus towards potentially threatening stimuli. Like any other emotion, anxiety goes along with physiological reactions, which may be more or less noticeable, and may impair behavior and physical wellness. In view of the psychophysiological reactions related with anxiety and anxiety disorders, it seems important to examine potential correlations between psychophysiological activity and the phenomena of hypervigilance. In fact, selective psychophysiological activation has repeatedly been found as a reaction to pathology-specific threatening stimuli in patients with anxiety disorders, whereas their psychophysiological responses appeared often to be blunted when they were submitted to neutral stimuli.
