Cognate Patient Care Insight Scale

Study Overview
=================
Brief Summary
-----------------
Schizophrenia is a disease of young adults that affects 1% of the general population. According to numerous studies, it has been estimated that between 50% and 80% of patients with schizophrenia do not consider to have a mental disorder and are therefore not aware of their disorders. A poor degree of insight is associated with poor compliance, a higher number of re-hospitalizations, altered social and relational functioning, and a higher number of suicides and violent behaviors. This is why insight, which is an essential dimension of psychopathology, must be evaluated, as it depends to a large extent on the therapeutic alliance, adherence to treatment, likelihood of relapse and prognosis.

Detailed Description
-----------------
Evaluation (test, re-test) This new tool for assessing insight will allow for a discrepancy in assessment and a more refined assessment with a view to developing specific care for the patient and / or the relative with regard to the three dimensions Evaluated: disease, treatment and functional implications

Official Title

Design Details

Primary Purpose: Other
Intervention Model: Single Group Assignment
Interventional Model Description: One arm in this study comprising 119 patients and one of their relatives
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: patients with schizophrenia and their designated relatives<br>Evaluation of the patient's insight (an inclusion phase, followed by two evaluation phases on D0 and D7) by the patient, his / her close and two caregivers (inter-judicial fidelity) | Other: Assessment of the insight of schizophrenic patients by themselves, their relatives and caregivers<br>* This study will evaluate the insight of the patient, something carried out in common practice within the Eastern Pole (CH Le Vinatier). This assessment will take place in the specific services where patients are cared for. It will make it possible to evaluate insight more closely by comparing the opinions of the three actors. There is no risk in this study. The study will be carried out over 2 years with a recruitment of 119 patients responding to the diagnosis of schizophrenia, taken care of within the Eastern Pole (Intra and Extrahospital services).<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Concurrent validity of the hetero-evaluation scale by studying its correlation with the results obtained, for the same persons, on the SUMD scale (Scale to Assess Unawareness of Mental Disorder) | Correlation higher than 0.40 in the Bravais-Pearson test between the caregiver's hetero-evaluation scale and the Scale to Assess Understanding of Mental Disorder (SUMD) | two years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correlation greater than 0.40 to inter-judge fidelity to Cohen's Kappa test | Inter-judicial fidelity will be measured with Cohen's Kappa test, which is a coefficient to measure the agreement between two qualitative variables with the same modalities. Conventionally, it is used to measure the degree of concordance between the stages Awarded by two judges. It can also be applied to measure an intra-observer agreement. The closer the ratio is to 1, the closer the gap between the observed chord proportion and the theoretical proportion of random chords approaches the gap between the perfect tuning of the two observers and their random match. The coefficient is always between -1 and 1 (maximum agreement). | two years | 
| Cronbach's alpha coefficient with a value of 0.7 measuring internal consistency | Internal consistency will be measured with the Cronbach alpha coefficient, sometimes referred to simply as the coefficient. Which is a statistic used especially in psychometrics to measure the internal consistency (or reliability) of the questions asked during a test (the answers to the questions on the same subject to be correlated). Its value is between 0 and 1, being considered acceptable from 0.7. It therefore allows estimation of the fidelity of the score to a test. | two years | 
| Correlation greater than 0.40 at the Bravais-Pearson test measuring test fidelity, re-testing | This coefficient makes it possible to detect the presence or absence of a linear relationship between two continuous quantitative characters. To calculate this coefficient, one must first calculate the covariance. Covariance is the mean of the product of deviations from the mean. The linear correlation coefficient of two characters X and Y is equal to the covariance of X and Y divided by the product of the standard deviations of X and Y. It can be shown that this coefficient varies between -1 and +1 | two years |
