Motive-specific Intervention for Negative Symptoms in Schizophrenia (MoNSS)
Treating Negative Symptoms of Schizophrenia With a Motive-specific Intervention: A Randomised Controlled Trial
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Clinically relevant negative symptoms are present in almost 60% of all patients suffering from schizophrenia. Motivational deficits seem to be one of the main barriers in the process of "functional recovery" among those patients and have been shown to be very treatment resistant. Effects of pharmacological compounds are at best moderate. There are some psychotherapeutic intervention studies that show promise but further controlled trials are needed to clarify the specific treatment effects.
Therefore, patients shall be encouraged to remember memories that stand in an association with specific motives. Motives are conscious and unconscious affect-based needs that are activated by behavior and influence behavior toward specific incentives in specific circumstances. They influence the selection of everyday goals and have influence on the degree of the progress people are making towards these goals. The intervention is based on the assumption that a positive expectation of the future is constituted among others by positive experiences from the past and at the same time increases the motivation for future behaviour. The activation of specific, motive-associated memories from autobiographical memory and their transformation into images of the future by means of imaginative methods could be a possible way of strengthening certain motives and thus increasing motivation for certain behaviour. This is mainly because there is evidence that psychosis patients have difficulties specifically remembering memories, i.e. those that happened on only one day. In addition, there is a diminished ability to create specific images of their personal future.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Intervention group
Motive-specific intervention; three appointments within two weeks, 30-45 minutes per session.
|
Three appointments are made with the patients of the intervention group within two weeks.
With an adaptation of the Autobiographical Memory Test (AMT) participants will be asked to recall events from the past and to imagine future events.
The time frame of 45 minutes for each intervention must be strictly adhered to.
Patients are additionally asked to complete tasks between the sessions.
All appointments take place in the Psychiatric University Hospital directly on the ward.
|
ACTIVE_COMPARATOR: Control group
Supportive conversations; three appointments within two weeks; 30-45 minutes per session.
|
Since we want to check whether the patients benefit from the specific intervention and not only from getting more speaking time, patients without the motive-specific intervention should also be given three sessions, in which no intervention takes place.
They will be carried out in the sense of supportive conversations (i.e.
conversations that do not follow a specific psychotherapy concept).
All appointments take place in the Psychiatric University Hospital directly on the ward.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Reduction of negative symptoms measured with the Brief Negative Symptom Scale (BNSS)
Time Frame: Baseline
|
The primary outcome criterion is the change and expected reduction of the severity of the negative symptoms in schizophrenia patients before and after the three-week motive-specific intervention.
We compare the change of severity between the patients of the intervention group and those in the control group.
Negative symptoms are measured with the Brief Negative Symptom Scale (BNSS) and items are rated on a 7-point-scale (0 = absent, 6 = severe).
|
Baseline
|
Long-term Reduction of negative symptoms measured with the Brief Negative Symptom Scale (BNSS)
Time Frame: 4 weeks after end of the psychotherapeutic intervention
|
Another primary outcome criterion is the change of the severity of the negative symptoms in schizophrenia patients who have received the motive-specific intervention compared to the control group patients in a follow-up appointment four weeks after termination of the intervention.
Negative symptoms are measured with the Brief Negative Symptom Scale (BNSS) and items are rated on a 7-point-scale (0 = absent, 6 = severe).

4 weeks after end of the psychotherapeutic intervention

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Correlation between the severity of negative symptoms and explicit motives measured with the Questionnaire for the Zurich Model of Social Motivation
Time Frame: Baseline
|
Secondary outcome criterion is the statistical significance and quality of the relationship between negative symptoms (measured with the Brief Negative Symptom Scale; items are rated on a 7-point-scale with 0 = absent and 6 = severe) and explicit reported motives.
|
Baseline
|
Correlation between the severity of negative symptoms and implicit motives measured with the Multi Motive Gitter
Time Frame: Baseline
|
Another secondary outcome criterion is the statistical significance and quality of the relationship between negative symptoms (measured with the Brief Negative Symptom Scale; items are rated on a 7-point-scale with 0 = absent and 6 = severe) and implicit motives.
