Integrated Psychological Therapy for Chronic Schizophrenia

Study Overview
=================
Brief Summary
-----------------
Background: The chronic phase of schizophrenia (CS) that extremely affects the way people think, feel and act, underlines the need for effective interventions in patients affected by this disorder. The Integrated Psychological Therapy appears in clinical practice guidelines as the reference therapy in the treatment of this type of patients. In this paper authors propose to include in this program a new module focused on Emotional Management Therapy in order to reinforce its effectiveness. The aim of this study is to describe the design of a study protocol for a randomized controlled trial in which the objective is to assess the efficacy of this modified IPT program in patients with CS compared to treatment as usual (pharmacological treatment and social and leisure activities in a Day Care Center). Methods/design: This is a randomized study with pre and post-treatment assessment and with a 6- and 12-month follow-up. Patients are to be randomly assigned to one of two treatments: (1) a experimental group: integrated psychological therapy in conjunction with emotional management therapy (IPT+EMT), composed of 2-hour biweekly 60 group sessions for 32 weeks, in addition to the treatment as usual (TAU), or (2) a control group (treatment as usual). Participants in both groups will be evaluated at baseline (pre-treatment) and at post-treatment after 8 months. The primary outcome will be that patients in the experimental group will show a greater improvement over participants in the control group in reducing symptoms and increasing emotional abilities, as well as in improving their quality of life. The secondary outcome will be that these results will maintain at the 6- and 12-month follow-up in the experimental group.

Discussion: This study provides the description of a clinical trial based on specific psychological intervention (IPT+EMT) for patients with chronic schizophrenia, aiming to improve lasting clinical and functional outcome.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Frankfurt Complaint Questionnaire (FBF-3) | (Assessing change)This is a self-report test composed of 98 items measuring the presence of the basic symptoms of schizophrenia. These are subjectively experienced disturbances at different domains including perception, thought, processing, language and attention that it could be the neurobiological features of schizophrenia. It contains 10 subscales and 4 factors. We will use a validated version for the Spanish population, in which Cronbach's alpha was above .95 and the test-retest reliability was above .60 | Pretreatment-Posttreatment (8months)-1 month-3 months-6 months-12 months follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Screen for Cognitive Impairment in Psychiatry (SCIP) | (Assessing change)This test assesses cognitive impairment through five areas: immediate and delayed verbal learning, working memory, verbal fluency and information processing speed. It is used for identifying cognitive impairment. The test-retest reliability ranged from 74 to 90 and Cronbach's alpha was 73. | Pretreatment-Posttreatment (8 months)-1 month-3 months-6 months-12 months follow-up | 
| Wechsler Adult Intelligence Scale-Third Edition (WAIS-III) | (Assessing change)Short forms of this scale have been designed for patients with schizophrenia . It assess cognitive functioning. Scores on these short forms are correlated (0.91) with the overall intelligence quotient (IQ) of the full scale in clinical patients. | Pretreatment-Posttreatment (8 months)-1 month-3 months-6 months-12 months follow-up | 
| Wisconsin Card Sorting Test (WCST) | (Assessing change)This test assesses attention span, planning and execution, and hence is considered a valid measure of executive function. We used the version of the test standardised and benchmarked for the Spanish population by TEA Editions. | Pretreatment-Posttreatment (8 months)-1 month-3 months-6 months-12 months follow-up | 
| Social Functioning Scale (SFS) | (Assessing change)We will use the short version of the scale, validated in a Spanish clinical sample, with a Cronbach's alpha of 0.76. | Pretreatment-Posttreatment-1 month (8 months)-3 months-6 months-12 months follow-up | 
| Lancashire Quality of Life Profile (LQoLP) | (Assessing change)This instrument assesses patient satisfaction with various aspects of their life, work, leisure time, religion, finances, living situation, safety, family relations, social relations, and health, as well as global wellbeing and self-esteem. | Pretreatment-Posttreatment (8 months)-1 month-3 months-6 months-12 months follow-up |
