Development of the insight scale for affective disorders (ISAD): modification from the scale to assess unawareness of mental disorder

Disability and its correlates among persons with bipolar disorder: Exploratory findings from the bipolar disorder course and outcome study from India (BiD-CoIN study)

Aim

This study aimed to evaluate the disability and its correlates in persons with Bipolar Disorder during the remission phase.

Materials and Methods

As part of the multicentric study, 773 patients with bipolar disorder, currently in clinical remission, were evaluated for disability on the Indian Disability Assessment Evaluation Scale.

Results

About one-fifth of the participants had some level of disability in the domain of self-care, one-third had some level of disability in the interpersonal domain, one-fourth had some level of disability in communication and understanding, and a maximum proportion (43.7%) had some disability in the domain of work. Overall, about one-fifth (18.4%) were considered to have a benchmark disability (i.e., disability >40%). In terms of correlates, those with a disability had a short duration of current remission, a higher number of manic and mixed episodes, a higher mean number of total episodes, spent more time in the episodes, had lower severity of the depressive episodes, higher residual depressive and manic symptoms, had overall higher manic affective morbidity, had a higher level of cognitive deficits, and had poorer insight.

Conclusion

A significant proportion of patients with bipolar disorder have disability in work domain, and the presence of residual symptoms of either polarity are associated with higher level of disability.

Prevalence of mixed features in patients with first-episode depression: An exploratory multicentric study

Background and Aim

There is limited literature on the prevalence of mixed features in patients with depression, especially from countries in Asia. Our aim was to evaluate the prevalence of "mixed features" in patients with first-episode depression.

Materials and Methods

Patients with first-episode depression were evaluated for the presence of mixed features as per the Diagnostic and Statistical Manual (DSM)-5 criteria. They were additionally evaluated on Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS).

Results

About one-sixth (16%) of the patients fulfilled the DSM-5 criteria for the mixed features specifier. The most common manic/hypomanic clinical feature was increased talkativeness or pressure of speech, followed by elevated expansive mood (12.5%), and inflated self-esteem or grandiosity was the least common feature (8.7%). Those with mixed features had higher prevalence of comorbid tobacco dependence and psychotic symptoms. In terms of frequency of depressive symptoms as assessed on HDRS, compared to those without mixed features, those with mixed features had higher frequency of symptoms such as depressed mood, insomnia during early hours of morning, work and activities, agitation, gastrointestinal somatic symptoms, genital symptoms, hypochondriasis, and poorer insight.

Conclusion

Mixed features specifier criteria were fulfilled by 16% patients with first-episode depression. This finding suggests that the extension of this specifier to depression can be considered as a useful step in understanding the symptom profile of patients with depression.

Development and validation of the Schedule for the Assessment of Insight in Alcohol Dependence (SAI-AD): Dimensions and correlates of insight in alcohol use disorder

INTRODUCTION

The objectives of this study were to develop a multidimensional, clinician-rated scale that assess impaired insight into illness in patients with alcohol use disorder (AUD) and to examine its reliability, validity and internal structure. Moreover, we investigated the relationships of overall insight and its dimensions with demographic and clinical characteristics in AUD.

METHODS

We developed the Schedule for the Assessment of Insight in Alcohol Dependence (SAI-AD), based on scales that has already been used in psychosis and other mental disorders. Sixty-four patients with AUD were assessed with SAI-AD. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships.

RESULTS

The SAI-AD demonstrated good convergent validity (r = -0.73, p < 0.001) and internal consistency (Cronbach's alpha = 0.72). Inter-rater and test-retest reliabilities were high (intra-class correlations 0.90 and 0.88, respectively). Three subscales of SAI-AD were identified which measure major insight components: awareness of illness, recognition of symptoms and need for treatment, and treatment engagement. Higher levels of depression, anxiety and AUD symptom severity were associated with overall insight impairment but not with recognition of symptoms and need for treatment, or with treatment engagement. Illness duration was specifically and positively associated with the treatment engagement component of insight.

CONCLUSIONS

Insight is a multidimensional construct in AUD and its major components appear to be associated with different clinical aspects of the disorder. The SAI-AD is a valid and reliable tool for the assessment of insight in AUD patients.

Prevalence and association of comorbid substance dependence on the course and outcome of bipolar disorder: Findings from the bipolar disorder course and outcome study from India (BiD-CoIN study)

AIM

To evaluate the prevalence of substance use disorder (SUD) and its association with the course and outcome of bipolar disorder (BD).

MATERIALS AND METHODS

A total of 773 patients with BD were recruited from 14 centers in different parts of India, and they were evaluated for the prevalence of comorbid substance dependence, course and outcome, subjective cognitive functioning, and disability.

RESULTS

About one-fourth (22.9%) of the participants had one or more substance dependence. In terms of specific substance of abuse, 136 (17.6%) had nicotine dependence, 80 (10.3%) patients had alcohol dependence, 13 (1.7%) had cannabis dependence, and nine (1.2%) had opioid dependence. Compared to those without comorbid substance dependence, those with a dual diagnosis (i.e., using at least one substance in a dependent pattern) were less educated, more often males, more often currently single, more often employed, had a lower number of depressive episodes per year of illness, had a higher number of manic and mixed episodes per year of illness in the first 5 years of illness, had a higher level of disability, and more often had a history of hospitalization and a history of receiving electroconvulsive therapy (ECT); also, a higher proportion of them had manic predominant polarity, more often had recurrent mania course, and were more often receiving a combination of lithium and valproate.

CONCLUSION

About one-fourth of BD patients have comorbid SUDs, and presence of SUD has a negative impact on the course and outcome of BD.

Factors associated with lifetime suicide attempts: findings from the bipolar disorder course and outcome study from India (BiD-CoIN study)

AIM

To evaluate the risk factors associated with lifetime suicide attempts in bipolar disorder (BD) patients.

METHODOLOGY

773 BD patients with a duration of illness of at least ten years, currently in clinical remission, were evaluated for suicidal attempts in their lifetime. Those with and without lifetime suicide attempt(s) were compared for various demographic and clinical risk factors.

RESULTS

242 (31.3%) patients had a history of at least one lifetime suicide attempt. Compared to those without lifetime suicide attempts, those with suicidal attempts were less educated, were more often females, spent more time in episodes, and had a significantly more number of total episodes (in the lifetime, first five years of illness, and per year of illness), had significantly more number of total depressive episodes (in the lifetime, first five years of illness, and per year of illness), spent more time in depressive episodes, had more severe depressive episodes, more often had depression as the first episode in the lifetime, spent more time in mania/hypomania/mixed episodes, had higher residual depressive and manic symptoms, more often had rapid cycling affective disorder pattern in the lifetime, use of cannabis in dependence pattern, had poorer insight into their illness and had a higher level of disability (especially in three out of the four domains of Indian disability evaluation assessment scale).

CONCLUSIONS

About one-third of the patients with BD have at least one-lifetime suicidal attempt, and those with suicide attempts usually have a poorer course of illness.

Suicidal Ideation in Bipolar Disorder: The Relation with Clinical and Sociodemographic Variables

INTRODUCTION

Bipolar disorder (BD) has the highest risk of suicide among all mental disorders. Thus, identifying factors related to suicidal ideation is essential for a better assessment of the risk of suicide in BD.

OBJECTIVE

To analyze the relationship between suicidal ideation and clinical and sociodemographic characteristics in BD patients.

METHOD

This is a cross-sectional study that included eighty individuals with BD. Information regarding sociodemographic data and history of attempted suicide were collected, and the Hamilton Depression Scale, Young Mania Rating Scale, Positive And Negative Syndrome Scale/positive symptom subscale, Clinical Global Impressions Scale for use in bipolar illness, Insight Scale for Affective Disorders, and Barratt Impulsiveness Scale were administered. The presence and severity of suicidal ideation were assessed using the Beck Scale for Suicidal Ideation.

RESULTS

All regression models significantly predicted suicidal ideation. In the model that had the lowest AIC score and the highest cross-validity, the severity of depressive and of manic symptoms (standardized β = 0.49, p < 0.001; standardized β = 0.42, p = 0.007), the insight level (standardized β = - 0.38, p = 0.012) and previous suicide attempt (standardized β = 0.20, p = 0.036) acted as predictors of suicidal ideation, while degree of impulsivity (β standardized = 0.13, p = 0.229) and educational level (standardized β = - 0.16, p = 0.108) did not give a significant contribution.

CONCLUSION

According to our results, more severe depression and mania symptoms, higher level of insight and a history of suicide attempt indicate the occurrence of suicidal ideation in BD.

Prevalence of psychotic symptoms and their impact on course and outcome of patients with bipolar disorder: Findings from the Bipolar Disorder Course and Outcome study from India (BiD-CoIN study)

AIM

Most of the available data on the prevalence and impact of psychotic symptoms on the course of bipolar disorder (BD) is from Western countries. We aimed to study the prevalence of at least one psychotic episode in the lifetime in patients with BD and its association with the long-term course and outcome.

METHODOLOGY

773 patients recruited as part of the Bipolar Disorder Course and Outcome study from India (BiD-CoIN study) were divided into 2 groups, based on the presence or absence of at least one psychotic episode in the lifetime.

RESULTS

326 (42.2%) patients had at least one psychotic episode in their lifetime. At least one psychotic episode in the lifetime was associated with overall more severe illness in terms of lower age of onset, a higher number of episodes in the first 5 years of illness; higher rates of BD-II, a higher rate of lifetime history of at least 1 suicide attempt, lifetime history of hospitalization, history of receiving Electroconvulsive Therapy, and a higher prescription rates of antipsychotics. However, presence of psychotics symptoms was associated with better cognitive functioning.

CONCLUSIONS

Our findings suggest that the presence of psychotic symptoms during episodes in patients with BD is associated with poorer course of BD.

Insight in nonpsychotic disorders: A new model of insight and a systematic review of measures

OBJECTIVE

There is substantial research examining insight in psychotic disorders and in some nonpsychotic disorders. However, there has been little attention given to many nonpsychotic disorders. Research on insight in psychosis distinguishes between cognitive and clinical insight. In most studies examining insight in nonpsychotic disorders, definitions and assessments of insight vary significantly. The purpose of this review is to suggest a definition of insight in nonpsychotic disorders such that it can be used across different disorders.

METHOD

We systematically review the extant literature of insight in nonpsychotic disorders and analyze the assessments used in order to determine how well they capture these two types of insight. Then, we discuss how these two constructs can provide better understanding of the phenomenology of insight in nonpsychotic disorders.

RESULTS

The systematic search resulted in 99 articles. These articles used 17 different methods of measuring insight, containing 127 questions. Results of the content analysis of items suggested that measures of insight used in nonpsychotic disorders do not distinguish between cognitive and clinical insight, but that most questions (90%) can indeed be reliably differentiated.

CONCLUSION

We provide a multidimensional model of cognitive and clinical insight in nonpsychotic disorders, emphasizing the complexity of assessment and the importance of accurately defining insight. Such definitions have important theoretical and clinical implications, offering a better understanding of the concept of insight in nonpsychotic disorders.

Application of the Delphi Method in the Study of Depressive Disorder

Depressive disorder is a common mental disorder that has a high prevalence and low visiting rate, which caused patients years lived with disability. Due to the complexity of the depressive disorder, the Delphi method is a better choice compared with other commonly used methods, which provides a new perspective for the prevention and treatment of depression. This article will summarize the clinical studies of depressive disorders using the Delphi method from four perspectives, and summarize the advantages and disadvantages of the Delphi method in depressive disorders research, arguing that the Delphi method can cross the gap between clinical research and clinical practice, and is a highly practical part of the research process.

Predominant polarity in bipolar disorder: Findings from the bipolar disorder course and outcome study from India (BiD-CoIN study)

AIM

This cross-sectional study aimed to assess the predominant polarity (PP) in patients with bipolar disorder (BD) and the factors associated with PP.

METHODOLOGY

For this study, 773 participants with at least 10 years of illness, were recruited from 14 centres, were evaluated using the National Institute of Mental Health- Retrospective Life Charts to assess the course of illness and PP was determined by both Barcelona proposal and the Harvard Index.

RESULTS

According to Barcelona proposal for PP, 20.6% of the patients belonged to depressive PP, 45.8% belonged to manic PP and 33.6% belonged to indeterminate polarity. According to Harvard index of PP, 31.6% of the patients belonged to depressive PP, 56.1% belonged to manic polarity and 12.3% of the patients could not be categorized into any of these categories and hence, were considered to have indeterminate polarity. Those with depressive PP were more often having BD-II, had later age of onset, spent more time in episodes, had higher residual depressive symptoms, had lower residual manic symptoms, more often had depression as the first lifetime episode, and less often had at least one psychotic episode.

CONCLUSION

In the Indian subcontinent, although the prevalence of PP is influenced by the definition used, the most common PP is that of mania.

A comparative study evaluating insight in different phase of illness among patients with bipolar disorder by using multiple scales

AIM

This cross-sectional study aimed to evaluate insight and its correlates among patients with bipolar disorder (BD).

METHODOLOGY

180 patients with BD were evaluated on Scale to Assess Unawareness of Mental Disorders (SUMD), Insight scale for affective disorders (ISAD), Mood Disorders Insight Scale (MDIS), and Beck Cognitive Insight Scale (BCIS).

RESULTS

About half of the patients were in clinical remission (N = 94; 52.2%), one-fifth (N = 37; 20.55%) were in the phase of mania and one-fourth (N = 49; 27.2%) were in a depression. There was no significant difference in the level of insight between those in clinical remission and those in depression except for one of the domains of BCIS. Patients with mania had poorer insight compared to those in remission and depression. In terms of association of insight as assessed by different scales, in the whole sample and all the three subgroups, SUMD current and past scores had a significant positive correlation with the ISAD total score. In the whole sample, among patients currently in remission and those currently in depression, ISAD total score had significant negative correlation with MDIS total score. Poorer insight as assessed on SUMD (current and past), ISAD and MDIS was associated with poorer medication adherence.

CONCLUSION

The present study demonstrates that patients with mania have poor insight when compared to the patients in clinical remission and depression. The present study also demonstrates that the assessment of clinical insight is not affected much by the type of scale used.

A Real-World Study of the Association between a Brief Group Psychoeducation and the Course of Bipolar Disorder

Although pharmacotherapy is considered the first-line treatment for bipolar disorders (BD), adjunctive psychoeducation has proven its effectiveness in improving self-management of the disease and reducing relapse rates. Few studies have evaluated the effect of brief group psychoeducation on pragmatic variables, such as the number of hospitalizations. The aim of the present study was to assess the mid-term effect of a four-session group psychoeducation on course-related variables in BD. Thirty-two individuals with BD were included in the study. Sixteen were exposed to psychoeducation and were matched to sixteen nonexposed individuals who received their usual treatment. Both groups were compared on insight, treatment adherence, change in the number of hospitalizations and visits to the emergency services, occurrence rate after intervention, and time to the first psychiatric hospitalization and the first urgent attendance. There was a significant reduction in the mean number of hospitalizations and urgent attendances in the exposed group in comparison to the nonexposed group. The first urgent attendance was significantly sooner in the nonexposed cohort. There were no differences between groups in any of the other variables. This intervention has shown benefits for pragmatic variables of the disease course and may be a feasible and cost-effective intervention to routinely implement in the management of BD.

Development and validation of the schedule for the assessment of insight in eating disorders (SAI-ED)

This study examined the reliability, validity and internal structure of the newly developed, interview-based Schedule for the Assessment of Insight in Eating Disorders (SAI-ED) and the relationships of insight with demographic and clinical characteristics in EDs. Ninety-four female patients - 44 with anorexia nervosa (AN) and 50 with bulimia nervosa (BN) - were assessed with SAI-ED. The Brown Assessment of Beliefs Scale was used to evaluate convergent validity of SAI-ED. Hierarchical cluster analysis and multidimensional scaling were used to identify insight components and assess their inter-relationships. The final 8-item SAI-ED demonstrated good psychometric properties. Inter-rater and test-retest reliabilities were high. Three subscales of SAI-ED were identified which measure major insight components: awareness of illness, awareness of symptoms, and treatment engagement. Patients with AN had significant lower score on SAI-ED than patients with BN. Impaired insight was associated with: (a) lower current and lowest lifetime BMI and more severe dietary restrain in AN, (b) illness duration, severity of overall ED symptoms, body-related concerns and obsessionality in BN. Insight is a multidimensional construct in EDs associated with different clinical aspects in AN and BN. The SAI-ED is a valid and reliable tool for the assessment of insight in EDs patients.

Clinical and Cognitive Correlates of Insight in Bipolar Disorder

Insight is greatly impaired in Bipolar Disorder (BD), especially during mania. Cognitive impairment is also present in BD. Despite that, few studies have investigated a possible association between these two aspects. The main goal of the current study is to compare BD affective states regarding performance in cognitive testing and investigate clinical and cognitive predictors for insight loss in BD. The study investigated a sample of 65 patients who were evaluated in one of the BD phases (mania, euthymia or depression). All the subjects underwent neuropsychological evaluation and completed the Insight Scale for Affective Disorders (ISAD). The relationship between level of insight and clinical/cognitive variables was analyzed through multiple regression models. No significant differences were found among BD phases regarding performance on cognitive testing. Insight was more impaired in mania then in depression or euthymia. Predictors for loss of insight were: severity of manic symptoms and impairments in selective attention (Symbol search test), divided attention (Trail making test) and inhibition (Stroop test). The sample size is a potential limitation of the current study. Nevertheless, the results suggest this had limited impact, with group differences being detected for a number of variables. The results found have important clinical importance, suggesting, for example, that rehabilitation of specific cognitive skills may improve insight in BD.

The Barcelona Orthorexia Scale (BOS): development process using the Delphi method

PURPOSE

Orthorexia nervosa is a currently investigated eating disorder proposed by US physician Steve Bratman, defined as pathological fixation on eating healthy food. This study aimed to develop, by consensus of experts, the basic items for a new questionnaire to evaluate some defining psychological features of orthorexia nervosa in English and Spanish language, the so-called Barcelona Orthorexia Scale (BOS).

METHODS

The initial item pool was composed of 105 items divided into six different content areas. To analyse the content of the items, a three-round Delphi study was developed, in which participants had to evaluate the representativeness and clarity of each item. Participants were chosen because of their knowledge on orthorexia and/or eating disorders.

RESULTS

58 experts, from 17 different countries, participated in the initial round and 30 in the last round. Items were added, rephrased, changed into another content area, modified or eliminated according to the participants' suggestions, partly due to the group's response, analysed statistically, and partly due to participants' recommendations.

CONCLUSIONS

64 items were obtained, with two versions in Spanish and English. The future BOS aims to provide a possible solution to the shortage of valid instruments to evaluate psychological features of orthorexia and to promote research on this field. Further analysis regarding validity and reliability is necessary to prove the BOS' value on this matter.

The relationship between insight and affective temperament in bipolar disorder: an exploratory study

INTRODUCTION

In recent years, the association between temperament and clinical characteristics of mood disorders has been studied. Most bipolar patients show deficits in their awareness of signs and symptoms. The relationship between affective temperament and insight in bipolar patients has not been carried out in the literature so far.

OBJECTIVE

To evaluate the relationship between affective temperament and insight in bipolar disorder.

METHOD

A group of 65 bipolar patients were followed during a year. Patients underwent a clinical assessment and were diagnosed using criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). Insight was evaluated through the Insight Scale for Affective Disorders (ISAD), and affective temperament, through the TEMPS-Rio de Janeiro. The relationship between affective temperament and insight was explored with Spearman rho correlations between scores on each item of the ISAD and on the TEMPS-Rio de Janeiro subscales.

RESULTS

In euthymic phases, bipolars with depressive temperament were associated with a higher level of insight about the consequences of the disorder; when in mania, patients showed better insight about having an affective disorder, presenting psychomotor alterations, and suffering from guilt or grandiosity. Similarly, bipolar patients with higher scores of anxious temperament, when in mania, had better insight on alterations in attention. Bipolar patients with higher scores of hyperthymic temperament, when in mania, showed the worst insight about thought disorder.

CONCLUSION

In addition to being determined by the phase of the disease and several varying symptoms, the level of insight in bipolar patients is also influenced by affective temperament.

Clinical correlates of loss of insight in bipolar depression

INTRODUCTION

Affective state may influence insight, especially regarding mania. Nevertheless, studies have so far suggested that depression seems not to significantly impair insight. To the best of our knowledge, this study pioneers the evaluation of how insight variations in bipolar depression correlate with clinical variables.

METHOD

A group of 165 bipolar patients, 52 of whom had depressive episodes according to DSM-5 criteria, were followed during a year. All patients underwent clinical assessment, and insight was evaluated through the Insight Scale for Affective Disorders (ISAD). Repeated-measures ANOVA was calculated comparing scores on the four ISAD factors (insight into symptoms, the condition itself, self-esteem and social relationships) in order to investigate differences in insight according to different objects. Correlational analysis explored which clinical symptoms were linked to reduced insight.

RESULTS

Worse total insight correlated with suicide attempt/ideation and fewer subsyndromal manic symptoms such as mood elevation, increased energy and sexual interest. Worse self-esteem insight was associated with not only suicide ideation/attempt but also with activity reduction and psychomotor retardation. Worse symptom insight also correlated with psychomotor retardation. Better insight into having an affective disorder was associated with more intense hypochondria symptoms. Finally, worse insight into having an illness was associated with psychotic episodes.

CONCLUSION

Our study found that symptoms other than psychosis - suicide ideation, psychomotor retardation and reduction of activity and work - correlate with insight impairment in bipolar depression.

The influence of current mood state, number of previous affective episodes and predominant polarity on insight in bipolar disorder

BACKGROUND

Although many studies have explored the effect of current affective episodes on insight into bipolar disorder, the potential interaction between current mood state and previous affective episodes has not been consistently investigated.

OBJECTIVE

To explore the influence of dominant polarity, number of previous affective episodes and current affective state on insight in bipolar disorder patients in euthymia or mania.

METHODS

A total of 101 patients with bipolar disorder were recruited for the study, including 58 patients in euthymia (30 with no defined predominant polarity and 28 with manic predominant polarity) and 43 in mania (26 with no defined predominant polarity and 17 with manic predominant polarity). Patients underwent a clinical assessment and insight was evaluated through the Insight Scale for Affective Disorders.

RESULTS

Bipolar disorder patients in mania had worse insight than those in euthymia, with no effect of dominant polarity. In addition, positive psychotic symptoms showed a significant effect on insight and its inclusion as a covariate eliminated differences related to mood state. Finally, the number of previous manic or depressive episodes did not correlate with insight level.

CONCLUSIONS

Mania is a predictor of loss of insight into bipolar disorder. However, it is possible that its contribution is linked to the more frequent presence of psychotic symptoms in this state. Dominant polarity and number/type of previous affective episodes have a limited impact on insight.

Correlation Between Insight Level and Suicidal Behavior/Ideation in Bipolar Depression

Suicide is a relatively common outcome along the course of bipolar disorder. Studies have shown a positive correlation between ideation or attempts of suicide and higher insight in schizophrenic patients. Nevertheless there are still few studies that evaluate the relationship between suicide and insight in mood disorders. Evaluate the relationship between insight and suicidal ideation or behavior in bipolar depression. A group of 165 bipolar patients were followed up along 1 year. Each patient's mood was assessed in every consultation according to DSM-IV-TR criteria. Suicidal ideation and behavior were prospectively assessed through item 3 of HAM-D whenever a major depressive episode was diagnosed. Insight was evaluated through the Insight Scale for Affective Disorders. A history of suicidal attempts was associated with worse insight in 60 patients with one episode of bipolar depression. The difference remained even when the supposed effect of depression over insight was controlled. No correlation between current suicidal ideation and insight level was found though. Our results suggest that a history of suicide attempts may correlate with higher impairment of insight in bipolar depression. No relationship was found between current suicidal ideation and insight.

Scale development: ten main limitations and recommendations to improve future research practices

The scale development process is critical to building knowledge in human and social sciences. The present paper aimed (a) to provide a systematic review of the published literature regarding current practices of the scale development process, (b) to assess the main limitations reported by the authors in these processes, and (c) to provide a set of recommendations for best practices in future scale development research. Papers were selected in September 2015, with the search terms “scale development” and “limitations” from three databases: Scopus, PsycINFO, and Web of Science, with no time restriction. We evaluated 105 studies published between 1976 and 2015. The analysis considered the three basic steps in scale development: item generation, theoretical analysis, and psychometric analysis. The study identified ten main types of limitation in these practices reported in the literature: sample characteristic limitations, methodological limitations, psychometric limitations, qualitative research limitations, missing data, social desirability bias, item limitations, brevity of the scale, difficulty controlling all variables, and lack of manual instructions. Considering these results, various studies analyzed in this review clearly identified methodological weaknesses in the scale development process (e.g., smaller sample sizes in psychometric analysis), but only a few researchers recognized and recorded these limitations. We hope that a systematic knowledge of the difficulties usually reported in scale development will help future researchers to recognize their own limitations and especially to make the most appropriate choices among different conceptions and methodological strategies.

Insight in bipolar mania: evaluation of its heterogeneity and correlation with clinical symptoms

BACKGROUND

Studies on insight in bipolar mania are not numerous and usually consider insight as a unitary construct.

OBJECTIVE

Evaluate how different facets of insight are affected in bipolar mania and investigate correlations between insight for each specific object in bipolar disorder and manic symptomatology.

METHOD

A group of 165 bipolar patients were followed during a year, with 51 patients having manic episodes according to DSM-IV-TR criteria. Patients underwent a clinical assessment and insight was evaluated through the Insight Scale for Affective Disorders.

RESULTS

The study found that insight regarding symptoms is worse than insight of having bipolar disorder, social relationships and self esteem. Moreover, poor global insight (total ISAD) correlates with more severe changes in mood, speech and thought structure, with worse insight about symptoms correlating with the same alterations and also with more severe symptoms of agitation/energy.

LIMITATIONS

Although a large sample of bipolar patients was followed up, the final sample composed of patients with at least one manic episode was relatively smaller. Moreover, the fact that the study was performed in a university hospital may have led to selection biases.

CONCLUSION

Results suggest that patients with BD are reasonably capable of identifying that their condition implies consequences but have more impaired awareness of their energy and activity levels. A lower level of insight specifically about symptoms correlates with more severe symptoms of agitation/energy, which suggests a psychomotor nucleus able to impair insight in mania.

Insight Across the Different Mood States of Bipolar Disorder

In bipolar disorder, levels of insight vary as a function of the mood state and appear to influence pharmacology compliance, quality of life, the presence of suicidal ideations, and aggressive behavior. To establish a comparison among different mood states in bipolar with regard to level of insight. Forty-eight patients were evaluated in different affective states (i.e., euthymia, mania, depression, and mixed state). Identifying information, sociodemographic data, and clinical records were recorded. The following scales were applied: Hamilton Depression Scale, Young Mania Rating Scale, Positive and Negative Syndrome Scale positive symptoms subscale, and Global Assessment of Functioning and Clinical Global Impressions Scale for use in bipolar disorder. Insight was evaluated using items 11 and 17 of the Young Mania Rating Scale and Hamilton Depression Scale, respectively. Insight in bipolar disorder was found to be more compromised during manic phases and mixed episodes than during periods of depression or euthymia. The factors associated with lower levels of insight were the following: shorter illness duration, older age, and greater severity in mania; the female gender and older age in depression; and shorter illness duration and more severe depressive symptoms in mixed episodes. In the same individual, levels of insight vary as a function of the affective state over the course of bipolar disorder and appear to be influenced by several clinical variables.

Insight in bipolar disorder: a comparison between mania, depression and euthymia using the Insight Scale for Affective Disorders

Objective: To evaluate whether having general insight into bipolar disorder and its symptoms is affected by the mood state of the patient, using the Insight Scale for Affective Disorders, a hetero-application scale for people with mood disorders.Methods: Ninety-five patients with bipolar disorder were evaluated and divided into different groups according to the mood state presented during assessment (i.e., euthymia, mania and depression). Sociodemographic and clinical data (Hamilton Depression Scale, Young Mania Rating Scale, and Clinical Global Impressions Scale) were recorded. Insight was evaluated using the Insight Scale for Affective Disorders.Results: Patients with bipolar disorder in mania show less insight about their condition than patients in depression or euthymia, and less insight about their symptoms than patients with depression, with the exception of awareness of weight change.Conclusions: Loss of insight during mania may have important implications for treatment compliance and adherence and needs to be taken into account in the clinical management of people with bipolar disorder.

Cross-cultural adaptation, validation and factor structure of the Insight Scale for Affective Disorders

BACKGROUND

In the last few decades, several tools for studying insight in bipolar disorders have been used. Olaya and colleagues developed the Insight Scale for Affective Disorders (ISAD), which consists of a scale measuring insight through hetero evaluation for patients with mood disorders. The objective of this work is to translate and adapt the original English version of the ISAD to Brazilian Portuguese (ISAD-BR) and to conduct an evaluation of its psychometric properties.

METHODS

Adaptation procedures included translation/back-translation and consultation with a panel of experts. 95 patients with the diagnosis of Type 1 bipolar disorder were evaluated with the final version of the ISAD-BR, which was applied, simultaneously, but independently, by two examiners. Internal consistency and inter-rater reliability were explored and the latent structure of the scale was investigated with principal axis factoring and promax rotation. A second-order factor analysis was conducted to test if the scale had a hierarchical factor structure.

RESULTS

The ISAD-BR showed good internal consistency and good inter-rater reliability. The analysis pointed to a four-factor solution of the ISAD-BR: awareness of symptoms associated with activity/energy; awareness of having a disorder; awareness of self-esteem and feelings of pleasure; and awareness of social functioning and relationships. The second order factor analysis indicated a hierarchical factor structure for the ISAD-BR, with the four lower-order factors loading on a single higher-order factor.

CONCLUSIONS

Insight into bipolar disorder is a multidimensional construct, covering different aspects of the condition and its symptomatology. Nevertheless, insight about activity/energy changes may be a crucial aspect of insight into bipolar disorder.
