Cognitive behaviour therapy (CBT) for depression by computer vs. therapist: patient experiences and therapeutic processes

This case series compares patient experiences and therapeutic processes between two modalities of cognitive behaviour therapy (CBT) for depression: computerized CBT (cCBT) and therapist-delivered CBT (tCBT). In a mixed-methods repeated-measures case series, six participants were offered cCBT and tCBT in sequence, with the order of delivery randomized across participants. Questionnaires about patient experiences were administered after each session and a semi-structured interview was completed with each participant at the end of each therapy modality. Therapy expectations, patient experiences and session impact ratings in this study generally favoured tCBT. Participants typically experienced cCBT sessions as less meaningful, less positive and less helpful compared to tCBT sessions in terms of developing understanding, facilitating problem-solving and building a therapeutic relationship.

Sialic acids in biological and therapeutic processes: opportunities and challenges

It is now well documented that carbohydrates play multiple roles in biological processes, and hence are interesting targets for chemical biology and medicinal chemistry programmes. This review focuses on a subset of carbohydrates, specifically sialic acid containing carbohydrates. It highlights their occurrence and diversity, and presents evidence for their roles in a range of biological pathways. It illustrates that they are targets for novel medicinal chemistry strategies for a range of therapeutic areas, including cancer and immunity. Case studies highlight opportunities and challenges in this area, and sialic acid based drugs that have entered clinical practice, and are promising candidates for future disease intervention schemes, are discussed. The review concludes by highlighting perspectives and emerging roles for these targets.

Narratives of healing: a case study of a young Liberian refugee settled in Australia

The Tree of Life group program is a narrative-based expressive arts intervention, designed to target the psychological difficulties faced by young people from refugee backgrounds. This study utilised a case study methodology to investigate the experience of a single adolescent from a Liberian background resettled in Australia, who participated in a manualised version of the Tree of Life program. The case study aimed to identify the underlying therapeutic processes that enabled the participant to adopt a preferred self-narrative. The participant was observed to demonstrate positive gains as a result of program participation. Five therapeutic factors were identified as particularly salient to the program’s success: the exploration of alternative stories of self; the fostering of group cohesion; the provision of corrective emotional experiences; the experience of outsider witnesses; and the instillation of hope. These factors were discussed in relation to working with young people from refugee backgrounds. Recommendations for future implementation of the Tree of Life program are provided.

La contribution des attentes à la régulation de la douleur

L’expérience de douleur et la réponse à son traitement sont teintées par les facteurs psychologiques, parmi lesquels figurent les attentes. Cette thèse propose de raffiner la compréhension de l’effet des attentes sur la régulation de la douleur par l’entremise de deux études quantitatives. D'abord, une étude expérimentale explore l'impact des attentes sur l'analgésie induite par contre-stimulation. Des volontaires sains ont été assignés à une condition contrôle ou à l’un des trois groupes au sein desquels les attentes étaient évaluées (attentes a priori) ou manipulées par l’entremise de suggestions (hyperalgésie ou analgésie). La douleur, l’anxiété et le réflexe nociceptif de flexion en réponse à des stimulations électriques ont été mesurés avant, pendant et après l’application d’un sac de glace. Les résultats suggèrent que les attentes a priori prédisent l’amplitude de l’analgésie, tandis que les attentes suggérées parviennent à potentialiser ou à bloquer les mécanismes endogènes d'inhibition de la douleur déclenchés par la contre-stimulation, indépendamment du niveau d’anxiété. Ensuite, une étude clinique se penche sur l'apport des attentes aux issues thérapeutiques de patients traités en centres multidisciplinaires de gestion de la douleur chronique. Préalablement au traitement, les attentes des patients quant aux résultats anticipés après six mois de traitement ont été évaluées. Les changements dans l’intensité douloureuse, les symptômes dépressifs, l’interférence de la douleur et la dramatisation face à la douleur, ainsi que l’impression de changement et la satisfaction face au traitement ont été évalués au suivi de six mois. Les résultats d'analyses de modélisation par équations structurelles appuient la relation prédictive entre les attentes et les issues thérapeutiques et soulignent l’impression de changement du patient comme variable médiatrice de cette association. En plus de se montrer supérieur à un modèle alternatif, ce modèle s'est avéré pertinent à travers différents sous-groupes. Dans l'ensemble, cette thèse contribue à démontrer le rôle déterminant des attentes dans le contexte de la douleur, tant au niveau physiologique que thérapeutique. Les conclusions qui se dégagent de cet ouvrage entraînent des retombées non négligeables et réitèrent la nécessité de considérer la perspective du patient afin d'optimiser les soins destinés au soulagement de la douleur.

Including the siblings of youth substance abusers in a parent-focused intervention : a pilot test of the best plus program

Substance use is common among young people and can escalate into significant problems for affected individuals and their families. Family responses can influence the course of youth substance use and its consequences for family members, including parents and siblings. Family-level interventions developed to date have neglected the important role that siblings can play. This article describes a pilot test of an intervention designed to assist parents and siblings affected by youth substance use and related problems. The BEST Plus intervention consisting of professionally-led, multifamily groups sequenced over eight sessions is described with reference to the intended therapeutic processes. Professionally observed and self-reported changes for family participants including siblings suggested that the program had a beneficial therapeutic impact. This evaluation of early impacts suggests the BEST Plus program
offers a promising means of assisting families to respond to substance use problems in young people.

Family recovery from youth substance use related problems : a pilot study of the BEST plus program

Youth substance use related problems are increasingly common, and families experience considerable stress in attempting to cope with these problems. A pilot study of 34 Australian parents from 21 families (38% sole parent families) participating in an 8-week group program, designed to assist families recover from youth substance use related problems, provided the context to explore family change processes. Participants reported a number of significant improvements over the course of the four groups that ran from late 2003 and through 2004. Regression analyses found general support for the program logic model in identifying significant associations between program-targeted parent changes and post-program improvements in stress symptoms and cohesive family behaviors. The study's limitations are noted.

Adolescent depressive disorders and family based interventions in the family options multicenter evaluation: study protocol for a randomized controlled trial

Background
There is increasing community and government recognition of the magnitude and impact of adolescent depression. Family based interventions have significant potential to address known risk factors for adolescent depression and could be an effective way of engaging adolescents in treatment. The evidence for family based treatments of adolescent depression is not well developed. The objective of this clinical trial is to determine whether a family based intervention can reduce rates of unipolar depressive disorders in adolescents, improve family functioning and engage adolescents who are reluctant to access mental health services.

Methods/Design
The Family Options study will determine whether a manualized family based intervention designed to target both individual and family based factors in adolescent depression (BEST MOOD) will be more effective in reducing unipolar depressive disorders than an active (standard practice) control condition consisting of a parenting group using supportive techniques (PAST). The study is a multicenter effectiveness randomized controlled trial. Both interventions are delivered in group format over eight weekly sessions, of two hours per session. We will recruit 160 adolescents (12 to 18 years old) and their families, randomized equally to each treatment condition. Participants will be assessed at baseline, eight weeks and 20 weeks. Assessment of eligibility and primary outcome will be conducted using the KID-SCID structured clinical interview via adolescent and parent self-report. Assessments of family mental health, functioning and therapeutic processes will also be conducted. Data will be analyzed using Multilevel Mixed Modeling accounting for time x treatment effects and random effects for group and family characteristics. This trial is currently recruiting. Challenges in design and implementation to-date are discussed. These include diagnosis and differential diagnosis of mental disorders in the context of adolescent development, non-compliance of adolescents with requirements of assessment, questionnaire completion and treatment attendance, breaking randomization, and measuring the complexity of change in the context of a family-based intervention.

A longitudinal evaluation of the resilient families randomized trial to prevent early adolescent depressive symptoms

This study aimed to evaluate whether an intervention prevented the development of depressive symptoms through the early years of secondary school (Grades 7 to 9 - mean ages 12.3 to 14.5 years) in Victoria, Australia. Twelve schools were randomized to a universal preventative intervention (including a student social relationship/emotional health curriculum, and parent/caregiver parenting education); 12 were randomized as control schools. Multivariate regression analyses used student self-report to predict depressive symptoms at 26-month follow-up (13-months after intervention completion) from baseline measures and intervention status (N = 2027). There was no overall intervention effect on depressive symptoms. However, intervention students with moderate symptoms whose parents attended parent education events had a significantly reduced risk of depressive symptoms at follow-up. Future evaluations of interventions of this type should investigate: therapeutic processes; methods to increase recruitment into effective parent education events; and the potential to target assistance to students with high depressive symptoms.

Work ability among hospital food service professionals: multiple associated variables require comprehensive intervention

The work of hospital food service is characterized by demands that can be associated with work ability - WA. The aim of this study was to evaluate factors associated with WA among hospital food service professionals and recommend intervention measures. This is a cross sectional study carried out in 2009, conducted in a hospital of Sao Paulo, Brazil. Participants were 76 (96.2%) of the eligible. They filled out a questionnaire including socio-demographic data, life styles, working conditions and WA. Multivariate linear regression analyses were performed. Factors associated with WA were age (p=0.051), over commitment (p=0.011), effort-reward ratio (p=0.002) and work injuries (p<0.001). In spite was a young population, age was associated with WA. Association with work injuries is consistent with the theoretical model that demonstrated that health status is the basis to maintain the WA. The association of effort-reward imbalance shows that issues related with work organization are relevant for these workers. The association of overcommittment suggests that workers recognize their responsibility with the therapeutic processes of patients. Results showed a number of features of different nature that should be taken into account when implementing measures to improve the WA, to be applied at different levels: individual, task and institutional.

Predicting Psychotherapy Dropouts: A Multilevel Approach

The role of therapeutic processes in predicting premature termination of psychotherapy has been a particular focus of recent research. The purpose of this study was to contrast outpatients who completed therapy and those who dropped out with respect to their self-reported in-session experiences of self-esteem, mastery, clarification and the therapeutic alliance. The 296 patients with mixed disorders were treated with an integrative form of cognitive–behavioural therapy without pre-determined time limit (M = 20.2 sessions). Multilevel analyses indicated that patients who did not completetreatment reported, on average, lower levels of self-esteem, mastery and clarification and lower ratings of their therapeutic alliance in treatment in contrast to patients who completed therapy. Patient-reported change in self-esteem experiences over the course of treatment turned out to be the strongest predictor of dropout from psychotherapy or successful completion. When dropout occurred before the average treatment length was reached, patients reported fewer clarifying experiences as early as the first session and their ratings of the therapeutic alliance were characterized by an absence of positive development. Both of these aspects seem to be involved in patients' decisions to leave treatment early. The findings underscore the importance of the therapeutic process in understanding the mechanisms behind treatment dropout. Copyright © 2014 John Wiley & Sons, Ltd.

Depth sensors-based upper limb motion capture system for functional neurorehabilitation

Versatile and accurate motion capture systems, with the required properties to be integrated within both clinical and domiciliary environments, would represent a significant advance in following the progress of the patients as well as in allowing the incorporation of new data exploitation and analysis methods to enhance the functional neurorehabilitation therapeutic processes. Besides, these systems would permit the later development of new applications focused on the automatization of the therapeutic tasks in order to increase the therapist/patient ratio, thus decreasing the costs [1]. However, current motion capture systems are not still ready to work within uncontrolled environments.

Monitorización y optimización de terapias de tele-neurorrehabilitación cognitiva

El Daño Cerebral Adquirido (DCA) se define como una lesión cerebral que ocurre después del nacimiento y que no guarda relación con defectos congénitos o enfermedades degenerativas. En el cerebro, se llevan a cabo las funciones mentales superiores como la atención, la memoria, las funciones ejecutivas y el lenguaje, consideradas pre-requisitos básicos de la inteligencia. Sea cual sea su causa, todo daño cerebral puede afectar a una o varias de estas funciones, de ahí la gravedad del problema. A pesar de los avances en nuevas técnicas de intervención precoz y el desarrollo de los cuidados intensivos, las afectaciones cerebrales aún no tienen tratamiento ni quirúrgico ni farmacológico que permita una restitución de las funciones perdidas. Los tratamientos de neurorrehabilitación cognitiva y funcional pretenden, por tanto, la minimización o compensación de las alteraciones ocasionadas por una lesión en el sistema nervioso. En concreto, la rehabilitación cognitiva se define como el proceso en el que personas que han sufrido un daño cerebral trabajan de manera conjunta con profesionales de la salud para remediar o aliviar los déficits cognitivos surgidos como consecuencia de un episodio neurológico. Esto se consigue gracias a la naturaleza plástica del sistema nervioso, donde el cerebro es capaz de reconfigurar sus conexiones neuronales, tanto creando nuevas como modificando las ya existentes. Durante los últimos años hemos visto una transformación de la sociedad, en lo que se ha denominado "sociedad de la información", cuyo pilar básico son las Tecnologías de la Información y las Comunicaciones (TIC). La aplicación de estas tecnologías en medicina ha revolucionado la manera en que se proveen los servicios sanitarios. Así, donde tecnología y medicina se mezclan, la telerrehabilitación se define como la rehabilitación a distancia, ayudando a extender los servicios de rehabilitación más allá de los centros hospitalarios, rompiendo las barreras geográficas, mejorando la eficiencia de los procesos y monitorizando en todo momento el estado y evolución del paciente. En este contexto, el objetivo general de la presente tesis es mejorar la rehabilitación neuropsicológica de pacientes que sufren alteraciones cognitivas, mediante el diseño, desarrollo y validación de un sistema de telemedicina que incorpora las TIC para avanzar hacia un nuevo paradigma personalizado, ubicuo y ecológico. Para conseguirlo, se han definido los siguientes objetivos específicos: • Analizar y modelar un sistema de telerrehabilitación, mediante la definición de objetivos y requisitos de usuario para diseñar las diferentes funcionalidades necesarias. • Definir una arquitectura de telerrehabilitación escalable para la prestación de diferentes servicios que agrupe las funcionalidades necesarias en módulos. • Diseñar y desarrollar la plataforma de telerrehabilitación, incluida la interfaz de usuario, creando diferentes roles de usuario con sus propias funcionalidades. • Desarrollar de un módulo de análisis de datos para extraer conocimiento basado en los resultados históricos de las sesiones de rehabilitación almacenadas en el sistema. • Evaluación de los resultados obtenidos por los pacientes después del programa de rehabilitación, obteniendo conclusiones sobre los beneficios del servicio implementado. • Evaluación técnica de la plataforma de telerrehabilitación, así como su usabilidad y la relación coste/beneficio. • Integración de un dispositivo de eye-tracking que permita la monitorización de la atención visual mientras los pacientes ejecutan tareas de neurorrehabilitación. •Diseño y desarrollo de un entorno de monitorización que permita obtener patrones de atención visual. Como resumen de los resultados obtenidos, se ha desarrollado y validado técnicamente la plataforma de telerrehabilitación cognitiva, demostrando la mejora en la eficiencia de los procesos, sin que esto resulte en una reducción de la eficacia del tratamiento. Además, se ha llevado a cabo una evaluación de la usabilidad del sistema, con muy buenos resultados. Respecto al módulo de análisis de datos, se ha diseñado y desarrollado un algoritmo que configura y planifica sesiones de rehabilitación para los pacientes, de manera automática, teniendo en cuenta las características específicas de cada paciente. Este algoritmo se ha denominado Intelligent Therapy Assistant (ITA). Los resultados obtenidos por el asistente muestran una mejora tanto en la eficiencia como en la eficacia de los procesos, comparado los resultados obtenidos con los de la planificación manual llevada a cabo por los terapeutas. Por último, se ha integrado con éxito el dispositivo de eye-tracking en la plataforma de telerrehabilitación, llevando a cabo una prueba con pacientes y sujetos control que ha demostrado la viabilidad técnica de la solución, así como la existencia de diferencias en los patrones de atención visual en pacientes con daño cerebral. ABSTRACT Acquired Brain Injury (ABI) is defined as brain damage that suddenly and unexpectedly appears in people’s life, being the main cause of disability in developed countries. The brain is responsible of the higher cognitive functions such as attention, memory, executive functions or language, which are considered basic requirements of the intelligence. Whatever its cause is, every ABI may affects one or several functions, highlighting the severity of the problem. New techniques of early intervention and the development of intensive ABI care have noticeably improved the survival rate. However, despite these advances, brain injuries still have no surgical or pharmacological treatment to re-establish lost functions. Cognitive rehabilitation is defined as a process whereby people with brain injury work together with health service professionals and others to remediate or alleviate cognitive deficits arising from a neurological insult. This is achieved by taking advantage of the plastic nature of the nervous system, where the brain can reconfigure its connections, both creating new ones, and modifying the previously existing. Neuro-rehabilitation aims to optimize the plastic nature by inducing a reorganization of the neural network, based on specific experiences. Personalized interventions from individual impairment profile will be necessary to optimize the remaining resources by potentiating adaptive responses and inhibiting maladaptive changes. In the last years, some applications and software programs have been developed to train or stimulate cognitive functions of different neuropsychological disorders, such as ABI, Alzheimer, psychiatric disorders, attention deficit or hyperactivity disorder (ADHD). The application of technologies into medicine has changed the paradigm. Telemedicine allows improving the quality of clinical services, providing better access to them and helping to break geographical barriers. Moreover, one of the main advantages of telemedicine is the possibility to extend the therapeutic processes beyond the hospital (e.g. patient's home). As a consequence, a reduction of unnecessary costs and a better costs/benefits ratio are achieved, making possible a more efficient use of the available resources In this context, the main objective of this work is to improve neuro-rehabilitation of patients suffering cognitive deficits, by designing, developing and validating a telemedicine system that incorporates ICTs to change this paradigm, making it more personalized, ubiquitous and ecologic. The following specific objectives have been defined: • To analyse and model a tele-rehabilitation system, defining objectives and user requirements to design the different needed functionalities. • To define a scalable tele-rehabilitation architecture to offer different services grouping functionalities into modules. • To design and develop the tele-rehabilitation platform, including the graphic user interface, creating different user roles and permissions. • To develop a data analysis module to extract knowledge based on the historic results from the rehabilitation sessions stored in the system. • To evaluate the obtained results by patients after the rehabilitation program, arising conclusions about the benefits of the implemented service. • To technically evaluate the tele-rehabilitation platform, and its usability and the costs/benefit ratio. • To integrate an eye-tracking device allowing the monitoring of the visual attention while patients execute rehabilitation tasks. •To design and develop a monitoring environment that allows to obtain visual attention patterns. Summarizing the obtained results, the cognitive tele-rehabilitation platform has been developed and evaluated technically, demonstrating the improvements on the efficiency without worsening the efficacy of the process. Besides, a usability evaluation has been carried out, with very good results. Regarding the data analysis module, an algorithm has been designed and developed to automatically select and configure rehabilitation sessions, taking into account the specific characteristics of each patient. This algorithm is called Intelligent Therapy Assistant (ITA). The obtained results show an improvement both in the efficiency and the efficacy of the process, comparing the results obtained by patients when they receive treatments scheduled manually by therapists. Finally, an eye-tracking device has been integrated in the tele-rehabilitation platform, carrying out a study with patients and control subjects demonstrating the technical viability of the developed monitoring environment. First results also show that there are differences between the visual attention patterns between ABI patients and control subjects.

Reducing Stigma toward Sexual Minorities: Acceptance-Based versus Traditional Safe Zone Training.

Homophobia continues to exist in society. Homonegative attitudes are often implicit and can be acquired without direct training, which makes them particularly resistant to change. Relational Frame Theory (RFT) is a behavior analytic account of learning processes and can explain these processes of indirect learning. RFT also suggests therapeutic processes for dismantling stigma using a therapy model named Acceptance and Commitment Therapy (ACT). This paper reviews previous research on traditional multicultural training, and addresses its shortcomings. Specifically, this paper makes the argument that traditional models encourage experiential avoidance and thus further perpetuate the processes that maintain stigma. While a handful of studies have examined stigma interventions using ACT, no ACT studies have been completed specifically on the stigma towards gay and lesbian individuals. This paper concludes with a research proposal for such a study.

Exploring the role of therapy process and outcome in interventions that target adolescent identity and intimacy

This study examined the feasibility of using a session impact measure with a sample of 24 at risk high school students participating in an intervention targeting identity and intimacy. Three therapists led 3 intervention groups with the same format. The study investigated the impact of therapy process, including Group, Facilitator, Skills, and Exploration impacts as measured by the Session Evaluation Form (SEF). The study also investigated the differential impact of session process on intervention outcome as measured by the CPSS, EPSI, RAVS, EIPQ and Youth Report Form. Analyses were conducted using descriptive statistics, frequencies, one-way analysis of variance (ANOVA), and Chi square tests. The results supported the utility of the SEF and they tentatively supported the impact of the therapist on participants' perceptions of therapeutic processes and on intervention outcome. In particular, Group 1 performed better than Group 3. This study found that the SEF is a useful session impact measure. ^
