Academic literature on the topic 'Hypomanic checklist'

Background: Undiagnosed and therefore inadequately treated hypomanic symptoms may be a leading cause of drug resistance in depression diagnosed as unipolar (major depressive disorder, MDD). The purpose of the IMPROVE study was to identify the rate of misdiagnoses in patients with treatment-resistant MDD by screening for the presence of previous hypomanic episodes, and to study the characteristics of those patients with a positive history of hypomania. Methods: Patients attending 29 psychiatric units throughout Italy with a diagnosis of MDD who were resistant to anti-depressant treatment were included in this multicentre, observational single visit study. The Hypomania Checklist 32 (HCL-32) was administered to detect underlying bipolarity. Results: Among the 466 enrolled patients, 256 (57.40%) were positive at screening for a previous hypomanic episode (HCL-32 ≥12), therefore suggesting a misdiagnosis. These patients scored higher than those with a negative history in both the “active/elated hypomania” (11.27±3.11 vs 3.57±3.05; P<0.0001) and “irritable/risk-taking hypomania” (2.87±2.03 vs 2.06±1.73; P<0.001) HCL-32 sub-scales. Patients with a positive history of hypomania were younger, had a higher number of previous depressive episodes and a higher frequency of comorbid conditions compared to those with a negative history. Conclusions: This study suggests that screening for hypomania in MDD-resistant patients facilitates identification of a notable proportion of undiagnosed cases of bipolar spectrum disorder. Patients with a positive history of hypomania at screening had a demographic/clinical bipolar-like profile that included young age, higher number of previous depressive episodes and higher frequency of comorbid conditions. They also had both higher active and irritable hypomania symptom scores.

BackgroundThere are no existing longitudinal studies of inflammatory markers and atopic disorders in childhood and risk of hypomanic symptoms in adulthood. This study examined if childhood: (1) serum interleukin-6 (IL-6) and C-reactive protein (CRP); and (2) asthma and/or eczema are associated with features of hypomania in young adulthood.MethodParticipants in the Avon Longitudinal Study of Parents and Children, a prospective general population UK birth cohort, had non-fasting blood samples for IL-6 and CRP measurement at the age of 9 years (n = 4645), and parents answered a question about doctor-diagnosed atopic illness before the age of 10 years (n = 7809). These participants completed the Hypomania Checklist at age 22 years (n = 3361).ResultsAfter adjusting for age, sex, ethnicity, socio-economic status, past psychological and behavioural problems, body mass index and maternal postnatal depression, participants in the top third of IL-6 values at 9 years, compared with the bottom third, had an increased risk of hypomanic symptoms by age 22 years [adjusted odds ratio 1.77, 95% confidence interval (CI) 1.10–2.85, p < 0.001]. Higher IL-6 levels in childhood were associated with adult hypomania features in a dose–response fashion. After further adjustment for depression at the age of 18 years this association remained (adjusted odds ratio 1.70, 95% CI 1.03–2.81, p = 0.038). There was no evidence of an association of hypomanic symptoms with CRP levels, asthma or eczema in childhood.ConclusionsHigher levels of systemic inflammatory marker IL-6 in childhood were associated with hypomanic symptoms in young adulthood, suggesting that inflammation may play a role in the pathophysiology of mania. Inflammatory pathways may be suitable targets for the prevention and intervention for bipolar disorder.

Background: A number of studies have documented high levels of hypomanic symptoms in those diagnosed with depression, suggesting a potential misdiagnosis of bipolar disorder as unipolar depression. Research suggests that undergraduate students have high levels of depression, but whether such misdiagnosis occurs in this population has not been examined. The aim of this study was therefore to examine levels of hypomania in undergraduate students reporting diagnosed depression. Methods: An international sample of undergraduate students completed the 32-item Hypomania Checklist (HCL-32). A cohort was analysed for this study, consisting of female undergraduate students reporting a formal diagnosis of depression (n=28). Results: Participants scored high on the HCL-32, with a mean total score of 19.9 (SD=5.4) out of 32. Overall, 85.7% (n=24) scored equal to or above the original cut off point of 14 suggested for bipolar II disorder. Conclusions: Two possible conclusions are suggested by this study. Firstly, there are high levels of hypomanic symptoms in undergraduate students diagnosed with depression, suggesting that a formal diagnosis of bipolar disorder should be pursued in those with high scores. Alternatively, the cut-off points previously suggested for the HCL-32 may not be accurate for use with undergraduate students.

BackgroundHypomanic symptoms may be a useful predictor of mood disorder among young people at high risk for bipolar disorder.AimsTo determine whether hypomanic symptoms differentiate offspring of parents with bipolar disorder (high risk) and offspring of well parents (control) and predict the development of mood episodes.MethodHigh-risk and control offspring were prospectively assessed using semi-structured clinical interviews annually and completed the Hypomania Checklist-32 Revised (HCL-32). Clinically significant sub-threshold hypomanic symptoms (CSHS) were coded.ResultsHCL-32 total and active or elated scores were higher in control compared with high-risk offspring, whereas 14% of high-risk and 0% of control offspring had CSHS. High-risk offspring with CSHS had a fivefold increased risk of developing recurrent major depression (P=0.0002). The median onset of CSHS in high-risk offspring was 16.4 (6–31) years and was before the onset of major mood episodes.ConclusionsCSHS are precursors to major mood episodes in high-risk offspring and could identify individuals at ultra-high risk for developing bipolar disorder.

Background:The Hypomania Checklist HCL-32 (Angst et al. 2005) is still in development as a screening instrument for hypomania in depressed patients and as a research tool.Update:The original HCL-32 was slightly modified, omitting one tricky question on consequences (HCL-32 R1) and recently (HCL-32 R2) by adding two new symptoms (gambling and overeating). It is currently available in 27 languages.New investigations include a Europe-wide GAMIAN study, individual studies in Brazil, Tunisia, Lebanon, Turkey, Korea, Taiwan and China, and the ongoing worldwide multicentre BRIDGE study.Results:1.new data have been collected on the re-test reliability in China and Sweden and correlations with the Mood Disorder Questionnaire in Brazil;2.exploratory and confirmatory factor analysis re-confirmed a two-factor structure (elated/overactive vs. irritable/risk taking) of the self-assessed hypomanic syndrome, replicable in over 1500 subjects from the community and patients with mood disorders across all cultures so far analysed;3.total item scores have repeatedly been shown to be independent of the current mood state (normal, low, high);4.adolescents/young adults in love feel high, and score comparably to bipolar-II patients on the HCL-32 (Brand et al 2007);5.89% of bariatric patients were also found to be high scorers on the HCL-32 (Alciati et al. 2007);6.studies with the HCL-32 in subjects with alcohol use disorders (AUD) (previously shown to be strongly associated with bipolarity) are ongoing.Future goals:Trans-cultural comparisons and evaluation of the questions on the consequences of hypomania for case-definition.

IntroductionRecent epidemiological studies suggest that the prevalence of bipolar disorder might be misdiagnosed initially as unipolar depression due to the difficulty to detect episodes of hypomania. The Hypomania Checklist (HCL-32), validated in Spanish, is a self-report questionnaire with 32 hypomania items designed to screen for hypomanic episodes.ObjectivesTo examine the prevalence of hypomania in patients with unipolar depression. Corroborate the efficacy of the HCL-32 to detect symptoms of hypomania.MethodsThe presence of hypomanic symptoms was assessed by the HCL-32 in a sample of 128 subjects diagnosed with bipolar I disorder (n = 30), bipolar II disorder (n = 1), unipolar depression (n = 57), and anxiety disorder (n = 15) according to DSM-IV-TR criteria. A control group of healthy subjects was selected (n = 25).ResultsThe discriminative capacity was analyzed by the ROC curve. The AUC was 0.65 which did not indicate a good capacity. The sensitivity (S), specificity (E) and prevalence (P) of hypomania in unipolar patients for the following cut-off points were :14: S = 81.6%,95%CI(69.8, 93.5); E = 30.1%,95%CI(19.7,40.6); P = 74.1%; 15: S = 77.6%,95%CI(64.9,90.3); E = 37.4%,95%CI(26.3,48.4); P = 67.2%; 16: S = 59.2%,95%CI(44.4,73.9); E = 55.4%,95%CI(44.1,74.0); P = 51.7%; 17: S = 55.1%,95%CI(40.2,70.1); E = 57.8%,95%CI(46.6,69.1); P = 48.3%.ConclusionsThe HCL-32 has a high sensitivity but a low specificity as screening instrument. This might explain the high proportion of hypomania found in this study. The difference with previous studies is that our sample was heterogeneous, unstable and serious. This suggests that the HCL-32 is not valid for any psychiatric sample. Future research should develop more specific instruments with better external validity.

Objective: This study aimed to investigate the prevalence and impact of hypomanic symptoms among healthcare professionals (HCPs) working night shifts, focusing on behavioral, mental, and physical health outcomes, as well as stimulant use and attitudes toward night shifts. Methods: A cross-sectional study was conducted among HCPs from Shaikh Zayed Hospital, Lahore, using the validated Hypomania Checklist (HCL-32). The survey included questions on demographic and occupational factors, stimulant consumption, and hypomanic symptoms, rated on a five-point Likert scale. Data were analyzed using SPSS version 25 for descriptive and inferential statistics, with p < 0.05 considered significant. Ethical approval was obtained, and participant confidentiality was ensured. Results: Among 200 respondents, 22.5% consumed coffee, 10.5% smoked, and 7.5% used drugs, while alcohol use was low (2%). Positive impacts of night shifts included increased energy (71.5%), confidence (77.5%), and optimism (59.5%). Negative outcomes were significant, with 53.5% reporting exhaustion, 48% irritability, and 49.5% distractibility. Behavioral changes included greater sociability (58%) and a playful personality (70.5%). Conclusion: The findings emphasize the need for structured mental health support and policy interventions to enhance the well-being of HCPs while maintaining high standards of patient care.

AbstractBackgroundDSM-IV definition of hypomania of bipolar-II disorder (BP-II), which includes elevated/irritable mood change as core feature (i.e., it must always be present), is not based on sound evidence.Study aimFollowing classic descriptions of hypomania, was to test if hypomania could be diagnosed on the basis of its number (9) of DSM-IV symptoms, setting no-priority symptom.MethodsConsecutive 422 depression-remitted outpatients were re-interviewed by a mood specialist psychiatrist using the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinician Version [a semi-structured interview modified by Benazzi and Akiskal (J Affect Disord, 2003; J Clin Psychiatry, 2005) to improve the probing for BP-II] in a private practice. History of episodes of subthreshold (i.e., 2 or more symptoms) and threshold (i.e., meeting DSM-IV criteria of elevated mood plus at least 3 symptoms, or irritable mood plus at least 4) hypomania, lasting at least 2 days, and which were the most common symptoms during the episodes, were systematically assessed.ResultsBipolar-II disorder (BP-II) patients (according to DSM-IV criteria, apart from hypomania duration) were 260, and major depressive disorder (MDD) patients were 162. Mood change was present in all BP-II by definition. The most common symptoms were overactivity, which was present in almost all BP-II, followed by elevated mood and racing thoughts. ROC analysis of the number of hypomanic symptoms predicting BP-II found that a cut point of 5 or more symptoms over 9 had the best combination of sensitivity (90%) and specificity (84%), and the highest figure of correctly classified (87%) BP-II. History of episodes of 5 or more hypomanic symptoms was met by almost all BP-II.LimitationsSingle interviewer.ConclusionsFollowing classic descriptions of hypomania, not setting any priority among the three basic domains of hypomania (mood, thinking, behavior), results suggest that a cutoff number of 5 symptoms over 9 (of those listed by DSM-IV) could be used to diagnose hypomania of BP-II. Diagnosing hypomania by counting a checklist of symptoms should make it easier to diagnose BP-II, and should reduce the current high misdiagnosis of BP-II as MDD, significantly impacting the treatment of depression.

Background/Objectives: Lithium is the gold standard for treating Bipolar Disorder (BD), but its effectiveness varies widely. While clinical and environmental factors may influence response, it remains unclear if screening tools can reliably predict lithium response outcomes. This study explores this potential using two widely used screening instruments for BD. Methods: A total of 146 patients with BD were evaluated. Lithium response was assessed using the Alda Scale, while hypomanic and manic symptoms were characterized through the Hypomania Checklist-32 (HCL-32) and the Mood Disorder Questionnaire (MDQ). Group differences in HCL-32 and MDQ scores were analyzed using ANOVA, and a multivariate model was employed to identify predictors of lithium response. Results: Of the total sample, 46 (31.5%) patients were identified as lithium responders based on the Alda Scale. Responders exhibited significantly higher HCL-32 scores compared to non-responders (p = 0.023), while no differences were observed in MDQ scores or other sociodemographic characteristics. Linear regression analysis revealed that HCL-32 scores were a significant predictor of Alda Scale scores, with no associations found for age, gender, or MDQ scores. Conclusions: Our study underscores the importance of considering hypomanic symptoms when estimating lithium response in BD, particularly by utilizing the HCL-32 during screening.

O HCL-32 é um questionário de 32 itens, de auto-aplicação, onde os sintomas são avaliados através de respostas do tipo \"sim\" (presente ou típico) ou \"não\" (não está presente ou atípico). Além disso, o HCL-32 tem 8 seções para avaliar a gravidade e o impacto dos sintomas sobre os diferentes aspectos da vida do paciente. A pontuação é obtida pela soma das respostas positivas para os 32 itens sobre hipomania. A versão original do HCL-32 foi traduzido e adaptado para o português brasileiro. A primeira versão do HCL-32 foi traduzida por nós, revisados por especialistas em transtornos de humor, bem como por um professor de português brasileiro. Foi então retro-traduzida por um professor de inglês americano. Dos indivíduos inicialmente selecionados, foram excluídos 27, 11 devido à presença de comorbidades com abuso de substância, e 16 devido à incapacidade de preencher corretamente o questionário. Assim, nossa amostra final ficou composta por 81 pacientes com TB (37 TBI; 44TBII), 42 com TDM, e 362 sujeitos de uma população não clínica. A consistência interna foi elevada, com um alfa de Cronbach de 0,793 para todo o HCL-32 VB, indicando que os itens do questionário são suficientemente homogêneos. Indivíduos com TB tiveram a maior pontuação no HCL-32 VB. A média de respostas afirmativas foi significativamente diferente de acordo com o diagnóstico. Analisamos a capacidade em diferenciar os diagnósticos através da curva ROC. A área sob a curva foi de 0.702, indicando a boa capacidade da escala para distinguir entre diagnósticos. A melhor combinação de sensibilidade (0.75) e especificidade (0.58) ocorreu com uma pontuação acima de 18. Esta pontuação distinguiu entre pacientes com TB e TDM. Para comparar as propriedades discriminativas do HCL-32 VB e MDQ VB, foram calculadas a sensibilidade e especificidade de ambos os questionários. A HCL-32 VB teve uma sensibilidade de 0.75 e especificidade de 0.58. O MDQ teve sensibilidade de 0.70 e especificidade de 0.58. Assim, a HCL-32 BV apresentou maior sensibilidade, mas a mesma especificidade que o MDQ. A análise fatorial resultou em nove fatores com autovalores > 1, explicando 53,1% da variância total. De acordo com o teste Scree, foi preferida uma solução com três fatores. O primeiro fator, com autovalor de 4,90, explicou 15,3% da variância e foi composto por 10 itens. Essa subescala reflete questões relacionadas com ativação/elação. O segundo fator, com autovalor de 3,48 (10,88% da variância), composto por 11 itens e sua estrutura inclui questões relacionadas com \"irritabilidade / comportamento de risco\". O terceiro fator, com autovalor de 1,56 (4,87% da variância), ficou composto por cinco itens e sua estrutura reflete questões relacionadas com \"desinibição / ativação sexual. Os parâmetros psicométricos de HCL-32 VB sugerem que é um instrumento útil para a detecção de hipomania em pacientes com transtornos de humor. O HCL-32 VB é um questionário rápido de auto-aplicação e de fácil interpretação<br>The HCL-32 is a 32-item self-administered questionnaire where symptoms are assessed through yes (present or typical) or no (not present or untypical) answers. In addition, the HCL-32 has 8 other sections evaluating the severity and impact of the symptoms on different aspects of patient\'s life. The score is obtained by adding the positive responses to the 32 symptoms of hypomania. The original version of the HCL-32 was translated and adapted to Brazilian Portuguese .The first draft of the Brazilian version was translated by us, reviewed by experts in mood disorders, as well as by a Brazilian-Portuguese teacher. It was then back-translated by an English (American) teacher. Of the individuals initially enrolled, 27 individuals were excluded; 11 due to the presence of comorbidities with substance abuse, and 16 due to inability to properly fill the questionnaires. Accordingly, our final sample comprised of 81 patients with BP (37 BPI; 44 BPII), 42 with MDD, and 362 subjects from a nonclinical population. Internal consistency was high, with a Cronbach\'s alpha of 0.793 for the entire HCL-32 BV, indicating that the items of the questionnaire are sufficiently homogeneous. Individuals with BP had the highest HCL-32 BV scores. The mean number of affirmative responses to the list of symptoms was significantly different according to diagnosis. We analyzed the scale\'s discrimination for BP trough the ROC curve. The area under the curve was 0.702 indicating the good ability of this screening scale. The best combination of sensitivity (0.75) and specificity (0.58) happened with a score above 18. This score discriminates between BP patients and MDD. To compare the discriminative properties of HCL-32 BV and MDQ, we calculated the sensitivity and specificity of both questionnaires. The HCL-32 BV had a sensitivity of 0.75 and specificity of 0.58. The MDQ had sensitivity of 0.70 and specificity of 0.58. Hence, the HCL-32 BV showed higher sensitivity but the same specificity than the MDQ. The factor analysis resulted in 9 factors with eigenvalues > 1, explaining 53.1% of the total variance. According to the Scree test, a 3-factor solution was preferred. The first factor, with an Eigenvalue of 4.90, explained 15.3% of the variance and comprised 10 items . This subscales structure reflects questions related to active/elated symptoms. The second factor, with an Eigenvalue of 3.48 (10.88% of the variance), comprised 11 items and its structure includes questions associated with irritable/risk-taking items. The third factor, with an Eigenvalue of 1.56 (4.87% of variance), comprised 5 itens and its structure reflect questions related to disinhibition/activation sexual. The psychometric parameters of HCL-32 BV suggest it as a useful instrument for the detection of hypomania in patients with mood disorders. HCL-32 BV is a brief, self-administered questionnaire of easy application and interpretation

碩士<br>國立成功大學<br>行為醫學研究所<br>96<br>Background: Bipolar disorder is a serious and disabling psychiatric disease, encompassing a wide range of clinical features, characterized by emotional dysregulation, specific risk-taking behaviors, impulsivity, impaired interpersonal relationship and depressive symptoms. Previous studies on course of bipolar disorder showed that patients with bipolar II (BP II) had longer duration of symptomatic period, more rapid-cycling features, more chronic course of illness, more depressive episodes, more psychosocial impairment and greater use of mental health services compared to those with bipolar I disorder. Moreover, high suicide risk, more lethal suicidality and higher rates of complete suicide were found in BP II patients; the prevalence rate of suicide attempt in BPII was as high as the range of 25% and 50%, and without appropriate treatment about 10% to 15% BP II patients would die of suicide. Delaying the use of mood stabilizers at the beginning of the course would also increase suicide risk, deteriorate symptoms and worsen patients' function. In current clinical practice, misdiagnosis and inappropriate treatment of bipolar disorder is very common; especially for BP II, studies displayed that it took 12 years for these patients to receive the correct diagnosis and treatment. Thus in order to lower the suicide risk of BP, how to enhance the correct diagnostic rate of these patients demands immediate attention. The recognition of (hypo)manic episodes is essential for the correct diagnosis of BP. The Hypomania CheckList (HCL-32) is developed to increase the detection of suspected or manifest but mistreated BP cases. We aimed to determine the accuracy and validity of the Chinese version of the HCL-32 in an adult psychiatric setting. We also compared the results with prior studies carried out in a comparable sample. Methods: Patients suffering from mood disorders completed the HCL-32 before being interviewed with the Schedule for Affective Disorder and Schizophrenia-Lifetime (SADS-L) to make DSM-IV diagnosis. The 4 day duration criterion for hypomania was replaced by a 2-day cut-off for BPII. The internal consistency and discriminatory capacity of the HCL-32 were analyzed. Results: Of the 306 individuals enrolled, 21 were excluded due to comorbid substance abuse/ dependence (n=4), refusal or inability to fill out the HCL-32 (n=17). Thus, the study included 94 patients with BPI, 140 with BPII and 51 with unipolar depression for further statistical analyses. Results indicated high internal consistency of the Chinese version of the HCL-32. The dual factor structure was confirmed. A score of 14 or more on the HCL-32 total scale distinguished between BP and MDD yielding a sensitivity of 80% and specificity of 73%. This scale also distinguished between BPI and BPII with a sensitivity of 63% and a specificity of 74% for the cut-off score of 21. Limitations: The sample size of MDD patients needs to be increased. Conclusions: The Chinese HCL-32 is a useful screening tool for BP in a psychiatric setting. Its performance is also comparable to that reported in previous studies.

Abstract Many patients who present with depression have an undiagnosed disorder in the bipolar spectrum. Bipolarity is associated with more frequent depressive episodes, increased suicide risk, a higher prevalence of comorbid substance use disorders, and several general medical conditions (e.g., migraine and hypothyroidism). Antidepressant treatment of bipolar depression without mood stabilization often has a poor outcome. Cultural issues complicate the diagnosis of depression with mixed features and mild bipolar disorder. Systematic screening with rating scales like the 32-item Hypomania Checklist, the Mood Disorder Questionnaire, and the Clinically Useful Depression Outcome Scale supplemented with questions for Diagnostic and Statistical Manual of Mental Disorders, fifth edition, mixed features facilitate identification of bipolarity in depressed patients; but the utility of specific questionnaire items and optimal cut points vary by culture and gender. Social class and life stage matter: Specific manifestations of hypomania might be tolerated or even normalized among adolescents and members of the upper class. Biomarkers might soon aid in identifying bipolarity in depressed patients.
