ABSTRACT Lack of insight in patients with bipolar I disorder has been associated with poor course and clinical outcome and compromised therapeutic compliance. Therefore, it is important to evaluate insight and use more specialized scales such as Mood Disorder Insight Scale (MDIS) in these patients. Our objective in this study was to assess validity and reliability of Persian version of MDIS.
A hundred forty five bipolar patients were selected from Iran Hospital of Psychiatry. They were interviewed by The Persian Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorder, 4th edition's (DSM-IV) axis I disorders (SCID-I) and the Scale to Assess Unawareness of Mental Disorder (SUMD). The translated version of MDIS in Persian was subsequently completed by patients.
The internal consistency was satisfactory (Cronbach alpha coefficients = 0.8). The test-retest reliability (coefficient alpha) was 0.95 (p < 0.01). Construct validity and concurrent validity were supported by factor analysis and Spearman rank correlation between MDIS and SUMD (0.85).
Persian version of the MDIS could be a useful instrument for assessing insight in patients with bipolar I disorder.

    ABSTRACT: The concept of insight as it applies to patients suffering from psychotic illness is reviewed. An exploratory study using structured interviews with patients recovering from psychotic illness indicated that the characteristics of insight fell into five main dimensions: (1) views about symptoms, (2) views about the existence of an illness, (3) speculations about etiology, (4) views about vulnerability to recurrence, and (5) opinions about the value of treatment. Some preliminary findings regarding the association of patterns of insight with diagnosis and chronicity of illness, and the implications of these findings for clinical work and for future research, are presented.

    ABSTRACT: The concept of insight into psychosis has received scant attention in the psychiatric literature. Drawing on sources such as phenomenology, clinical research and experimental psychology, it is proposed that insight is not an 'all-or-none' phenomenon but is composed of three distinct, overlapping dimensions, namely, the recognition that one has a mental illness, compliance with treatment, and the ability to relabel unusual mental events (delusions and hallucinations) as pathological. A scheme is proposed to standardise the assessment of insights to assist further research.

    ABSTRACT: It is frequently reported that patients with psychotic disorders have poor insight into their illness. Previous research has suggested that poor insight may have considerable power in predicting the long-term course of chronic mental disorders and an impact on patients' compliance with treatment plans. The authors, proposing that insight is best viewed as a multidimensional phenomenon, developed the Scale to Assess Unawareness of Mental Disorder, which samples discrete and global aspects of insight across a variety of manifestations of illness. This article reports on a reliability and validity study of the scale. The study subjects were 43 patients with schizophrenia and schizoaffective disorder. Various aspects of insight into illness were evaluated with the scale. In addition, ratings of psychopathology, course of illness, and compliance with treatment were made. Item variability was high and normally distributed, supporting the authors' contention that insight can be rated on a continuous rather than dichotomous scale. Results of the analyses examining the relations between the various dimensions of insight assessed and the psychopathology, course, and compliance variables were generally as hypothesized. Convergent validity with other global measures of insight was found, and aspects of poor insight were correlated with poorer compliance and course of illness. Examination of the interrelations among the four insight subscales revealed that these subscales sample independent phenomena. The Scale to Assess Unawareness of Mental Disorder has good reliability and validity and has certain advantages over previous measures of insight, suggesting the usefulness of a multidimensional view of this complex concept.
