A New Adaptation of Integrated Psychological Treatment for Patients With Schizophrenia

A New Adaptation of Integrated Psychological Treatment for Patients With Schizophrenia

Integrated psychological treatment (IPT)—which was developed by a research group in Bern, Switzerland, for patients with schizophrenia—is a distinctive and practical approach to rehabilitation.1 What sets IPT apart from other treatments is that it can integrate classic approaches of developing social skills with new approaches of managing neurocognitive deficits and cognitive bias for patients with schizophrenia.

IPT also focuses on helping patients deal with the difficulties that they encounter on a daily basis. It is based on a hierarchical progression of learning that allows individuals to acquire skills that are essential for social functioning and to reappropriate meaningful social roles.2 The goal of IPT is to enhance psychosocial functioning and patients' abilities to cope with environmental stressors in their everyday lives. The first incarnation of IPT was published in the late 1970s,3 and the first IPT manual was printed in 1988 in German.4 The manual has since been translated into 10 languages, including English.

The effectiveness of IPT has been demonstrated in 30 independent evaluations worldwide and is documented in a meta-analysis in which IPT had greater positive mean effect sizes than placebo (group-attending attention training) or standard care.5 Findings from the analysis showed that all dependent variables, including psychopathology, neurocognitive deficits, and social behaviors, were positively affected. In addition, the beneficial effects of IPT increased during an average follow-up period of 8.1 months. These favorable effects were obtained at different stages of illness and in different clinical and organizational settings.

The results of a multisite implementation study (N = 55) in natural contexts involving 9 clinical settings in Quebec support these conclusions.6 Improvements were observed in general symptoms, cognitive and social functioning, and quality of life, despite differences among 9 groups of participants. The overall change was positive for patients in the early stages of the disease, for patients who had been treated for 5 to 10 years in a traditional outpatient clinic, and for patients who were receiving long-term care. In addition, skill levels continued to improve for 3 to 4 months after the intervention ended.

IPT is recommended as an effective intervention for patients with schizophrenia (in illness management and recovery skills practice).7 It does not, however, encompass all care that should be offered to these patients (ie, collaborative and optimal psychopharmacology, case management, assertive community treatment, psychotherapy, family psychoeducation, supported housing, and supported employment). For this reason, clinicians must offer IPT within the framework of a comprehensive care and rehabilitation process.

Basic principles of IPT

IPT is a cognitive-behavioral approach to rehabilitation. The content of clinical activities proposed under IPT combines the principles of neurocognitive remediation8,9 (including the concept of social cognition) and classic cognitive therapy,10,11 as well as social skills development and problem-solving approaches.12,13 The therapeutic activities of IPT make it possible for a clinician to intervene at a patient's level of cognitive dysfunctions (ie, lack of attention, poor working memory, deficit of executive functioning), false perceptions and interpretations (ie, positive symptoms, cognitive schema, emotional perception), social inabilities, and management of stressful and emotionally charged situations (ie, coping style).

The original IPT approach consisted of 5 modules.1 Later, a French version of IPT14 introduced an additional module, emotional management training (EMT).15 The new Quebec version of IPT, adapted from the French version, also includes EMT.16 It consists of 6 modules (Figure) [Figure restricted. Please see print edition for content.] of increasing complexity that are delivered to groups of 8 to 12 participants over 9 to 12 months (in 2-hour sessions twice weekly).14,16

The 6 modules are designed so that each builds on the previous module. Learning gradually takes place through a series of progressive and well-framed situations that are cognitively simple, have few social or emotional requirements, and direct the patient toward experimenting with increasingly complex situations with progressively greater relational and emotional demands. In this way, participants are gradually given exercises and placed in situations that require ever-greater skills and that increasingly approximate real life.

According to Brenner's model, improved cognitive and perceptual skills have a positive effect on social behavior by reducing environmental stressors and cognitive distractions.1 Improving patients' social skills and their ability to deal with the demands of everyday life also has a positive impact by reducing cognitive and perceptual difficulties and closing the cognitive-behavioral feedback loop required to maintain the functional behaviors that are needed for a better social life.

IPT subprograms

Module 1, cognitive differentiation, is intended to exercise basic cognitive functions (attention/concentration, memory, and the creation/manipulation of concepts) through abstract exercises in the form of learning games. These exercises solicit and improve patients' existing cognitive functions and permit the acquisition of compensatory strategies to reduce residual cognitive deficits. Module 1 not only stimulates cognitive functions, it also establishes the kind of safe learning environment that is essential for effective group processes, enabling participants to have successful experiences.2

Module 2, social perception, consists of participants working together to analyze images (slides or video sequences) that represent a variety of social situations. Initially, simple cognitive content and emotionally neutral situations give way to progressively more complex content in more emotionally charged situations. Participants are asked to describe objective aspects of the images and to interpret their content. The aims are to avoid inappropriate interpretations, focus on the objective aspects of the image, and correct mistaken cognitive schemata that often occur in patients with schizophrenia. Module 2 also allows facilitators to make an initial assessment of the cognitive schemata of participants that will have an impact on the way they manage their emotions and solve everyday problems (covered in modules 5 and 6).

Module 3, verbal communication, addresses patients' basic communication skills through learning games or role-playing. Participants acquire listening skills, develop understanding, and learn appropriate responses. Clinicians work with participants on the various communication deficits that are frequently observed in patients with schizophrenia (eg, poor language, loss of content, circumstantial language, perseveration). This is a key module in which greater demand is placed on individual participants, but in which progress is made toward establishing a cohesive spirit within the group. Thus, this module is well suited for exercises on acquiring new adjustment strategies proposed by clinicians.

Module 4, social skills, is a logical follow-up to the preceding module. It aims to develop an appropriate range of social skills in a variety of specific social situations. Participants are encouraged, according to their capacities and needs, to work through different social situations they encounter in their everyday lives using cognitive-behavioral techniques (eg, instructions, role-playing, modeling, repetition, reinforcement). This module is largely based on classic approaches to developing social skills.12,13

Module 5, emotional management, helps patients develop the best strategies for managing emotions. The depiction of an emotion presented in a given situation (in a slide or short video sequence) allows participants to do a detailed analysis of their emotional reactions, question the appropriateness of the strategies they have adopted, search for better-alternative strategies, and then experiment with the strategies they have selected.

This module is an essential element to strengthen the learning skills that are needed for the management of stressful situations. The emotional intensity of stressful situations can disrupt the learning processes of patients and may prevent them from applying the skills they acquired during previous modules. Module 5 provides more emotional stability for the patients in their everyday lives and facilitates the application of compensatory strategies that are specifically adapted to the emotional vulnerability and residual symptoms of patients. This module reinforces the exercises on perceptions and erroneous interpretations that began in module 2. Module 5 was inspired by Green and Nuechterlein's model (social cognition)8 and by cognitive-behavioral therapy principles.10

Module 5 is demanding in that it requires clinicians to possess a solid mastery of group facilitation skills. The challenge is to maintain the established theoretical framework while increasing the complexity (cognitive, perceptual, and social) of the situations presented.16

Module 6, problem solving, involves analyzing problems experienced by the participants. These situations are examined according to the following steps of problem solving: identify and analyze the problem, engage in the cognitive conceptualization of the problem, search for alternative solutions, discuss the solutions, select a solution, implement the solution, and evaluate the solution's effectiveness. This module requires participants to use the skills they have acquired in the preceding modules and proposes real-life situations and exercises that facilitate the transfer of learning skills. Table 1 provides some examples of the types of exercises used in each module.

Generalization and maintenance of learning skills

Despite making some tentative suggestions about how the newly acquired knowledge can be generalized and maintained, previous versions of IPT proposed few therapeutic activities for attaining this objective.1,14 The revised Quebec version of IPT (the result of an implementation study carried out in Quebec) seeks to fill this gap by using 3 additional therapeutic modalities16:

  • Exercises or tasks to be done at home.
  • Integration outings in the patient's day-to-day environment (in vivo sessions).
  • Additional booster sessions after completion of IPT.
