Clinical and cognitive insight in panic disorder: phenomenology and treatment effects in internet cognitive behavior therapy

Clinical observations suggest that individuals with panic disorder (PD) vary in their beliefs about the causes of their panic attacks. Some attribute these attacks to psychological factors, while others to physiological or medical factors. These beliefs also extend to whether individuals perceive panic attacks as dangerous. In other areas of psychiatric nosology, these phenomena are commonly called clinical insight (recognition of disorder and the need for treatment) and cognitive insight (the ability to reflect on one's beliefs). Despite its importance, limited research exists on insight in PD and its relation to symptoms and treatment outcomes. This study examines clinical and cognitive insight in 83 patients with PD who received internet-based cognitive behavioral therapy, investigating their relationship with symptoms, treatment outcomes, and changes in insight. We assessed patients using interview and self-report measures of insight and symptoms. Clinical and cognitive insight were correlated and both constructs improved significantly during treatment. Good clinical insight pretreatment was positively correlated with more severe pretreatment symptoms. Pretreatment clinical and cognitive insight were not correlated with symptom change or attrition. Greater change in clinical and cognitive insight was related to greater change in symptoms. The findings highlight the significance of clinical and cognitive insight in PD, and the importance of distinguishing between them. This suggests the need to develop interventions according to patients' level of insight, particularly focusing on those lacking insight. Further research is essential to advance our understanding of the relationship between insight and the phenomenology and treatment of PD.

'Excessive and Unreasonable': The Relation Between Clinical Insight and Clinical Correlates and Treatment Outcomes in Obsessive-Compulsive Disorder Across the Life Course

Individuals with mental disorders possess varying levels of clinical insight-the degree to which one understands that they are afflicted with a mental disorder and that their symptoms are manifestations of this psychopathology. Although clinical insight in OCD is thought to play an especially important role in determining various clinical characteristics and treatment outcomes, insight has not been sufficiently addressed developmentally, the importance of which this review will elucidate. Findings from this review suggest that clinical insight is typically associated with more complex cases and worse treatment outcomes across the life course, and also reveal nuances between pediatric and adult OCD cases with low insight. Implications of these findings, future research directions, and recommendations for the field are discussed.

Examining the relationship between cognitive factors and insight in panic disorder before and during treatment

Individuals with Panic Disorder (PD) often have impaired insight, which can impede their willingness to seek treatment. Cognitive processes, including metacognitive beliefs, cognitive flexibility, and jumping to conclusions (JTC) may influence the degree of insight. By understanding the relationship between insight and these cognitive factors in PD, we can better identify individuals with such vulnerabilities to improve their insight. The aim of this study is to examine the relationships between metacognition, cognitive flexibility, and JTC with clinical and cognitive insight at pretreatment. We investigate the association among those factors' changes and changes in insight over treatment. Eighty-three patients diagnosed with PD received internet-based cognitive behavior therapy. Analyses revealed that metacognition was related to both clinical and cognitive insight, and cognitive flexibility was related to clinical insight at pre-treatment. Greater changes in metacognition were correlated with greater changes in clinical insight. Also, greater changes in cognitive flexibility were related to greater changes in cognitive insight. The current study extends previous studies suggesting potential relationships among insight, metacognition, and cognitive flexibility in PD. Determining the role of cognitive concepts in relation to insight may lead to new avenues for improving insight and can have implications for engagement and treatment-seeking behaviors.

Clinical insight level predicts successful quit or control attempts during the first three months of outpatient addiction treatment

INTRODUCTION

Low clinical insight in psychiatry is defined as poor recognition of one's mental illness, including disability to self-evaluate symptom severity. It has been reported as common in addiction and is associated with lower treatment compliance. Longitudinal studies suggest that low clinical insight could be linked to more relapse. However, association with successful quit attempts remains unknown.

OBJECTIVE

Our objective was to examine the prospective link between baseline clinical insight level and self-reports of successful attempts to quit / control use during the first 3 months of outpatient addiction treatment.

METHODS

Participants were recruited from the ADDICTAQUI cohort at outpatient treatment intake for substance or behavioral addictions. They completed a baseline evaluation using the Addiction Severity Index (ASI), the Mini International Neuropsychiatric Interview (MINI), and the modified Hanil Alcohol Insight Scale (m-HAIS) with a follow-up ASI 3 months later. Data were analyzed using multiple logistic regression and non-parametric tests.

RESULTS

Lower clinical insight level at baseline was associated with less successful quit / control attempts during the first 3 months of outpatient treatment compared to a higher clinical insight level, controlling for sociodemographic factors, baseline addiction severity, and comorbidities (n = 54; exp(B) = 0.76; p (FDRcor) = 0.033).

CONCLUSION

Poor clinical insight may be a barrier to treatment success, and future studies should examine underlying mechanisms.

Novel Clinical Insights into Spinal Hemangioblastoma in Adults: A Systematic Review

BACKGROUND

Hemangioblastomas (HBs) are well-vascularized, benign central nervous system tumors and the third most common primary spinal cord tumor after astrocytoma/ependymoma, occurring sporadically or as a part of autosomal dominant von Hippel-Lindau disease, in which tumors are often multiple and prone to relapse. Spinal HBs are commonly located in the cervical cord and associated with a syrinx formation. Owing to location and growth trends, they may cause significant neurological deficit, impairing quality of life. We conducted a systematic review to understand better clinical insights into spinal HB in adults and compare spinal HB versus posterior cranial fossa HB.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for conducting systematic reviews, we reviewed the English-language literature on adult spinal HB in the MEDLINE/PubMed database over the last 40 years.

RESULTS

We reviewed 237 articles on adult spinal HB and analyzed national and continental distribution, clinical symptoms, tumor location and presence of syringomyelia, treatment strategies and postoperative complications, histology and immunochemistry, and treatment outcomes. We compared individual characteristics in sporadic and von Hippel-Lindau disease spinal HBs. Finally, we compared features of posterior cranial fossa and spinal HBs.

CONCLUSIONS

Spinal cord HBs most commonly have a dorsal intramedullary location. Total surgical tumor resection is the first treatment option; preoperative embolization may be performed to reduce intraoperative bleeding and surgical time. HBs located in the spine have decreased mortality and rate of infection, but increased rates of cardiopulmonary complications compared with HBs in the posterior cranial fossa.

Clinical insight, cognitive insight and metacognition in psychosis: Evidence of mediation

OBJECTIVE

Schizophrenia is increasingly understood as an interactive network of disturbances in different elements of self-awareness. In this study we have examined the relationship between disturbances in two forms of awareness: cognitive insight and clinical insight by exploring whether their relationship is mediated by a third form of larger awareness: metacognition.

METHODS

Participants were 41 outpatients with schizophrenia and 37 outpatients with early episode psychosis gathered in Moscow, Russia. Metacognition was assessed with the Metacognition Assessment Scale - Abbreviated. Verbal memory and positive symptoms were assessed for use as additional mediators.

RESULTS

Mediation analyses revealed that after accounting for the effects of positive symptoms and verbal memory, the relationship between the self-reflection domain of cognitive insight and clinical insight was significantly mediated by overall metacognitive capacity. Further, positive symptoms were a significant mediator between the cognitive insight self-reflection domain and clinical insight. Neither metacognition nor positive symptoms or verbal memory were found to mediate the relationship of the cognitive insight domain of self-certainty with clinical insight.

CONCLUSIONS

Decrements in some forms of ability to reflect upon one's thinking may reduce the ability to form complex and integrated ideas of oneself and others, leading to less coherent and complete accounts of the experience of schizophrenia.

The role of illness engulfment in the association between insight and depressive symptomatology in schizophrenia

Good clinical insight in schizophrenia tends to be associated with better outcomes, but also with increased depression. We hypothesized that illness engulfment, a process whereby an individual's self-concept becomes defined solely by illness and the 'patient identity' becomes primary, is a mediating and/or moderating factor in the association between insight and depressive symptomatology in schizophrenia. Mediation and moderation analyses were conducted using the PROCESS macro on data from 140 individuals with enduring schizophrenia who completed measures of the insight dimension of 'Awareness of Illness and Need for Treatment' (AINT), the Calgary Depression Scale, and the Modified Engulfment Scale. There was a significant indirect effect of AINT, mediated through engulfment, on depressive symptomatology (95% CI = 0.017 to 0.143), independent of duration of illness and current severity of positive symptoms. Moderation analysis revealed a significant interaction effect between level of engulfment and AINT, on depressive symptomatology, b = 0.005, t (134) = 2.814, p < .01, 95% CI = 0.002 to 0.009, controlling for the duration of illness and current severity of positive symptoms. At low levels of engulfment, higher AINT was associated with lower depression scores; while at high levels of engulfment, higher AINT was associated with higher depression scores. Illness engulfment may be an important process by which insight influences mood in schizophrenia. Insight interventions that also target engulfment may reduce the risk of increased depressive symptomatology.

Validity of the Birchwood insight scale in patients with schizophrenia spectrum- and bipolar disorders

The aim of this study is to investigate the validity of the Norwegian version of the Insight Scale (IS) in large and representative samples of patients with schizophrenia spectrum disorders, bipolar I disorder and bipolar II disorder. A total of 997 participants were included (schizophrenia spectrum disorders: 557; bipolar I disorder: 282; bipolar II disorder: 138). Confirmatory factor analysis was conducted to investigate the construct validity and bivariate correlational analysis was applied to investigate convergent validity. Confirmatory factor analyses indicated a reasonable model fit to the original three-factor subscale structure of the IS in all three diagnostic groups. The IS total score and its subscales correlated significantly with both the insight items in the Young Mania Rating Scale and the Positive and Negative Syndrome Scale in both schizophrenia spectrum disorders and bipolar I disorder. In the bipolar II disorder group, however, the IS subscales correlated poorly with both the observer-rated measures. Our study supports the construct validity of the IS in both schizophrenia spectrum disorder- and bipolar disorder populations. The study also demonstrates that patients' self-reports of insight correspond to observer-based single item ratings of insight in bipolar I disorder and schizophrenia spectrum disorders.

Clarifying associations between cortical thickness, subcortical structures, and a comprehensive assessment of clinical insight in enduring schizophrenia

BACKGROUND

The relationship between poor insight and less favorable outcomes in schizophrenia has promoted research efforts to understand its neurobiological basis. Thus far, research on neural correlates of insight has been constrained by small samples, incomplete insight assessments, and a focus on frontal lobes. The purpose of this study was to examine associations of cortical thickness and subcortical volumes, with a comprehensive assessment of clinical insight, in a large sample of enduring schizophrenia patients.

METHODS

Two dimensions of clinical insight previously identified by a factor analysis of 4 insight assessments were used: Awareness of Illness and Need for Treatment (AINT) and Awareness of Symptoms and Consequences (ASC). T1-weighted structural images were acquired on a 3 T MRI scanner for 110 schizophrenia patients and 69 healthy controls. MR images were processed using CIVET (version 2.0) and MAGeT and quality controlled pre and post-processing. Whole-brain and region-of-interest, vertex-wise linear models were applied between cortical thickness, and levels of AINT and ASC. Partial correlations were conducted between volumes of the amygdala, thalamus, striatum, and hippocampus and insight levels.

RESULTS

No significant associations between both insight factors and cortical thickness were observed. Moreover, no significant associations emerged between subcortical volumes and both insight factors.

CONCLUSIONS

These results do not replicate previous findings obtained with smaller samples using single-item measures of insight into illness, suggesting a limited role of neurobiological factors and a greater role of psychological processes in explaining levels of clinical insight.

Dimensions of insight in schizophrenia: Exploratory factor analysis of items from multiple self- and interviewer-rated measures of insight

OBJECTIVE

Insight in schizophrenia is regarded as a multidimensional construct that comprises aspects such as awareness of the disorder and recognition of the need for treatment. The proposed number of underlying dimensions of insight is variable in the literature. In an effort to identify a range of existing dimensions of insight, we conducted a factor analysis on combined items from multiple measures of insight.

METHOD

We recruited 165 participants with enduring schizophrenia (treated for >3years). Exploratory factor analysis was conducted on itemized scores from two interviewer-rated measures of insight: the Schedule for the Assessment of Insight-Expanded and the abbreviated Scale to assess Unawareness of Mental Disorder; and two self-report measures: the Birchwood Insight Scale and the Beck Cognitive Insight Scale.

RESULTS

A five-factor solution was selected as the best-fitting model, with the following dimensions of insight: 1) awareness of illness and the need for treatment; 2) awareness and attribution of symptoms and consequences; 3) self-certainty; 4) self-reflectiveness for objectivity and fallibility; and 5) self-reflectiveness for errors in reasoning and openness to feedback.

CONCLUSIONS

Insight in schizophrenia is a multidimensional construct comprised of distinct clinical and cognitive domains of awareness. Multiple measures of insight, both clinician- and self-rated, are needed to capture all of the existing dimensions of insight. Future exploration of associations between the various dimensions and their potential determinants will facilitate the development of clinically useful models of insight and effective interventions to improve outcome.

On the Road to Recovery psychological therapy versus treatment as usual for forensic mental health patients: study protocol for a randomized controlled feasibility trial

BACKGROUND

On the Road to Recovery (OTRTR) is a brief low intensity group psychological therapy that aims to improve patients' insight into their mental disorder and develop adaptive coping skills to help manage distress. OTRTR is currently delivered in forensic mental health services in Scotland. However, to date, this therapy has not been evaluated as to its effectiveness or safety for forensic patients.

METHODS

This is a parallel-group feasibility randomized controlled trial with single-blind assessments comparing OTRTR therapy to treatment as usual (TAU) for forensic mental health patients. Fifty participants will be recruited from high, medium, and low secure forensic mental health services in Scotland. Participants will receive OTRTR for approximately 12 weeks or continue treatment as usual for 12 weeks. The trial's primary aims relate to testing the acceptability and feasibility of key trial procedures that would be necessary for a definitive RCT of OTRTR. The secondary aims include estimating therapeutic effect sizes on clinical outcomes including insight and coping skills. The study design also features an adverse event monitoring plan to estimate the safety of OTRTR for participants, as well as use of intensive longitudinal methods to identify "key ingredients" to the OTRTR therapy protocol.

DISCUSSION

This study will inform the design and sample size for a future full-scale randomized controlled trial (RCT), which will be conducted to determine the effectiveness of the On the Road to Recovery intervention in improving forensic mental health patients' clinical insight and coping skills.

The relationship between clinical insight and cognitive and affective empathy in schizophrenia

Background

Schizophrenia is often associated with poor clinical insight (unawareness of mental illness and its symptoms) and deficits in empathy, which are important for social functioning. Cognitive empathy has been linked to clinical insight while affective empathy and its role in insight and pathology have received mixed evidence.

Methods

Instruments assessing symptomatology (Positive and Negative Syndrome Scale; PANSS), clinical insight (Scales to assess awareness of mental disorders; SUMD), and cognitive and affective empathy were administered to 22 participants with first episode and chronic schizophrenia and 21 healthy controls. Self-report, parent-report, and performance based measures were used to assess cognitive and affective empathy (The interpersonal reactivity index; IRI/Reading the Mind in the Eyes Test/Faux Pas) to reduce bias and parse shared variance.

Results

Age of onset, gender, and symptomatology emerged as significant predictors of poor clinical insight. Additionally, the fantasy subscale of the IRI as reported by parents emerged as a positive predictor while the personal distress (parent report) subscale emerged as a negative predictor of awareness into mental illness. There were significant differences on performance-based measures of empathy between the control and schizophrenia groups.

Conclusion

Findings suggest that affective empathy is relatively intact across phases of illness whereas cognitive empathy abilities are compromised and could be targets for psychotherapy intervention.

Longitudinal trajectory of clinical insight and covariation with cortical thickness in first-episode psychosis

Among people with a first-episode of psychosis, those with poorer clinical insight show neuroanatomical abnormalities in frontal, temporal and parietal cortices compared to those with better clinical insight. Whether changes in clinical insight are associated with progressive structural brain changes is unknown. We aimed to evaluate 1) associations between clinical insight and cortical thickness at a baseline assessment, 2) covariation between clinical insight and cortical thickness across baseline, one-year and two-year follow-up assessments, and 3) the predictive value of clinical insight for cortical thickness at one-year and two-year follow-ups. Scale for the assessment of Unawareness of Mental Disorder ratings and magnetic resonance imaging scans were acquired at baseline, one-year, and two-year follow-ups in 128, 74, and 44 individuals with a first-episode psychosis, respectively. Cortical thickness metrics were then computed at baseline, one-year and two-year follow-ups and analyzed with linear mixed models. At baseline, clinical insight was not significantly associated with cortical thickness in any region. Longitudinal mixed effects models showed that a worsening in clinical insight between the one-year and two-year assessments was significantly associated with cortical thinning in dorsal pre-central and post-central gyri. Cortical thinning in left fusiform gyrus at two-years was predicted by poorer clinical insight at baseline. Results suggest that poor clinical insight soon after the onset of a first-episode psychosis may lead to progressive cortical changes in temporal lobe, while changes in clinical insight during the second year covary with cortical thinning in circumscribed dorsal frontal and parietal cortices.

Theory of mind correlates with clinical insight but not cognitive insight in patients with schizophrenia

Research on the relationship between insight and social cognition, in particular Theory of Mind (ToM), in schizophrenia has yielded mixed findings to date. Very few studies, however, have assessed both clinical insight and cognitive insight when examining their relationships with ToM in schizophrenia. The current study thus investigated the relationship between clinical insight, cognitive insight, and ToM in a sample of 56 patients with schizophrenia and 30 healthy controls. Twenty-seven patients were classified as low in clinical insight according to their scores on the 'insight' item (G12) of the Positive and Negative Syndrome Scale (PANSS). Moreover, cognitive insight and ToM were assessed with the Beck Cognitive Insight Scale (BCIS) and the Yoni task, respectively. The results indicated that patients with poor clinical insight performed worse on tasks of second-order cognitive and affective ToM, while the ToM performance of patients with high clinical insight was equivalent to that of healthy controls. Furthermore, while clinical insight was correlated with ToM and clinical symptoms, cognitive insight did not correlate with clinical insight, ToM, or clinical symptoms. Clinical insight thus appears to be an important factor related to ToM in schizophrenia.

Factors predicting the presence of impaired clinical insight in liaison psychiatric patients assessed in the Emergency Room

OBJECTIVES

There are limited studies on the factors that can predict the presence of impaired clinical insight specifically in an Emergency Room (ER) psychiatric patient population. The objective of this study is to examine the factors that can predict the likelihood that a patient presenting to the ER will have impaired clinical insight.

METHODS

Nineteen independent demographic and clinical factors contained on data assessment tools for 337 patients assessed by the crisis team in the ER over 6 months were compiled and analysed using SPSS Version 20 with univariate analyses and logistic regression.

RESULTS

Patients who were unemployed or had a history of self-harm or had psychotic symptoms on mental state examination were about two, three and six times, respectively, more likely to have impaired clinical insight compared with those who were employed, had no history of self-harm or had no psychotic symptoms on mental state examination, controlling for other factors in the logistic regression model.

CONCLUSION

Patients who are unemployed, have a history of self-harm or have psychotic symptoms following as psychiatric assessment in the ER may benefit from an insight-oriented psychotherapy.

The relationship between cognitive insight and quality of life in schizophrenia spectrum disorders: Symptom severity as potential moderator

Cognitive insight is implicated in the formation and maintenance of hallucinations and delusions. However, it is not yet known whether cognitive insight relates to broader outcome measures like quality of life. In the current study, we investigated whether the component elements of cognitive insight-self-certainty and self-reflectiveness-were related to quality of life for 43 outpatients with schizophrenia or schizoaffective disorder. Cognitive insight was assessed using the Beck Cognitive Insight Scale (BCIS) while quality of life was assessed with Quality of Life Scale (QLS). We tested whether this relationship was moderated by clinical insight and symptom severity using the Scale to Assess Unawareness of Mental Disorder (SUMD) and the Positive and Negative Syndrome Scale (PANSS). We found that self- reflectiveness had an unmoderated positive relationship with quality of life. Self-certainty was associated with better quality of life for people with more severe symptoms. Theoretical and clinical implications of these findings are discussed and areas of future research are proposed.

Cognitive insight in schizophrenia patients and their biological parents: a pilot study

BACKGROUND

Clinical insight in schizophrenia patients is partly associated with familial environment but has been poorly studied to date. We aimed to explore (1) the relationship between parents' cognitive insight and their offspring's; (2) the relationship between parents' cognitive insight and their clinical insight into the disease of their offspring; and (3) the clinical and cognitive determinants of cognitive insight in parents.

METHODS

Cognitive insight was assessed in 37 patient-biological parent pairs/dyads with the Beck Cognitive Insight Scale (BCIS). Other measures included the Scale to assess Unawareness of Mental Disorder and cognitive assessments.

RESULTS

We found no significant association between parents' cognitive insight and their offspring's. Conversely, a positive association between parents' cognitive insight and parents' insight into their offspring's symptoms was found. Better awareness of their offspring's specific symptoms was associated with lower levels of overconfidence in one's beliefs and with BCIS total score. BCIS Self-Certainty and BCIS total score were associated with better executive functioning and verbal comprehension.

CONCLUSIONS

Better insight into their offspring's symptoms is associated with cognitive insight in biological parents of schizophrenia patients. Our results support the integration of cognitive intervention targeting parents' cognitive flexibility in family psychoeducational programs and provide an important first step towards developing a more refined understanding of the factors involved in insight into symptoms of illness in parents of schizophrenia patients.
