This study aimed to characterize the association between paranoid ideation without psychosis (PIP) and suicide attempts in a general population. A total of 12,532 adults were randomly selected as the study sample through one-person-per-household method. Subjects completed a face-to-face interview. Among 12,532 subjects, 471 (3.76%) met criteria for the PIP group. The PIP group was younger with more divorced/widowed/separated and lower income than the non-PIP group. The PIP group showed more than fivefold higher lifetime suicide attempt (LSA) rates and ninefold multiple attempt rates than the non-PIP group. Among PIP symptoms, "spouse was being unfaithful" showed the strongest association with LSA (adjusted odds ratio [AOR], 4.49; 95% confidence interval, 2.95-6.85). Major depressive disorder (MDD) in combination with PIP was associated with a higher risk of LSA (AOR, 15.39; 95% confidence interval, 9.63-24.59) compared with subjects without MDD or PIP. In conclusion, PIP, especially "doubting spouse," was significantly associated with LSA. PIP in combination with comorbid MDD showed higher risk of LSA than subjects without PIP or MDD.

Background: Subthreshold hypomania is defined as a distinct period of elevated, expansive or irritable mood lasting for at least four days, but insufficient to fulfill the criteria of hypomania. This study aimed to investigate the association between suicidality and subthreshold hypomania in subjects with and without major depressive disorder (MDD).Methods: Face-to-face interviews were completed for 12,526 adults, randomly selected through a one-person-per-household method, using the Korean version of the Composite International Diagnostic Interview (K-CIDI) and a questionnaire relative to lifetime suicide attempts (LSA).Results: Of the 12,526 participants, 11,701 did not have MDD, and 825 were diagnosed with MDD. The MDD with subthreshold hypomania group (n = 72) revealed significantly higher rates of LSA and post-traumatic stress disorder (PTSD) than those without (n = 753). Compared to the no MDD without subthreshold hypomania group (n = 11,571), the no MDD with subthreshold hypomania group (n = 130) showed a significantly higher prevalence of suicidality and comorbid conditions. In multivariate logistic regression analyses of depressive symptoms, subthreshold hypomania was significantly associated with morning worsening of mood. The MDD with subthreshold hypomania group was significantly associated with LSA (AOR=16.82, 95% CI 9.81-28.83, p< 0.001), compared to the no MDD group without subthreshold hypomania. Compared to the MDD without subthreshold hypomania group, the MDD with subthreshold hypomania group revealed a significant association with LSA (AOR=2.08, 95% CI 1.20-3.62, p< 0.001).Conclusions: A history of subthreshold hypomania doubled the risk of LSA in patients with MDD compared to those without subthreshold hypomania.

Abstract Objective Somatic pain is an important risk factor for suicide and suicidal behaviors. However, the association between the number of somatic pain conditions and lifetime suicide attempts (LSA) has not been well established yet. Therefore, the objective of this study was to examine associations between LSA and multiple somatic pain (MSP), singe pain, and no pain in a nationwide survey. Methods A total of 12,532 adults were randomly selected from the population using the one-person-per-household method. Each participant completed a face-to-face interview using the Korean Composite International Diagnostic Interview (K-CIDI) with Suicide Module, and the Barratt Impulsiveness Scale 11 (BIS-11). The MSP was defined as pain in two or more parts of one's body, including abdominal pain, back pain, arthralgia, arm or leg pain, chest pain, headache, menstrual pain, dysuria, genital pain, and other pain. Results Among 12,532 subjects, 858 (6.85%) had MSP. Among the three groups (MSP, single pain, and no pain) of subjects, the MSP group had higher percentages of females, those with lower education, and divorced/widowed/separated individuals. However, there were no significant differences in monthly income or residence among the three groups. The MSP group showed four times higher suicide attempts and six times higher multiple attempts than did the no pain group. The BIS total score of the MSP group was the highest among the three groups. Genital pain showed the highest odds ratio for LSA. The higher the number of somatic pain, the higher the odds ratios were for LSA, major depressive disorder (MDD), and anxiety disorders. Subjects having both MSP and MDD showed a significant association with LSA (AOR = 14.78, 95% CI 10.08–21.67, p < 0.001) compared to those having neither somatic pain nor MDD. Conclusions MSP was significantly associated with LSA. It had greater prevalence among individuals reporting a higher number of somatic pain conditions and comorbid MDD. Highlights • Multiple somatic pain (MSP) is significantly associated with lifetime suicide attempt (LSA). • MSP group showed the highest impulsivity scores compared with single or no pain groups. • The higher the number of somatic pain, the higher the odds ratios were for LSA, major depressive disorder, and anxiety disorders. • Careful screening of suicide risks should be mandatory in patients with MSP and comorbid mental disorders.

Background: Alcohol-induced disinhibition (AID) is defined as a "loss of restraint over some form of behavior after drinking alcohol regardless of its amount". Although many previous studies have investigated on alcohol use disorder and suicide attempt, few studies have focused on AID and suicide.Methods: A total of 9461 adults who had a history of drinking completed a face-to-face interview using the Korean version of Composite International Diagnostic Interview (K-CIDI) with the Suicide Module, and Barratt Impulsiveness Scale 11 (BIS-11). In this study, we defined the AID group as those who had been involved with the two antisocial behaviors, including fights, being arrested or dangerous driving, according to the K-CIDI.Results: Among 9461 subjects, 564 were classified as the AID group (5.96%). The AID group had a significantly higher number of lifetime suicidal ideation, plan, attempt, and multiple attempts, and higher BIS-11 scores than non-AID group. The total scores of BIS-11 of the AID group reported the highest score compared with other psychiatric disorders. The AID group experienced more frequently three types of alcohol withdrawal symptoms, including nervousness, heart beating fast, and feeling weak. Compared with subjects without both AID and MDD, subjects with both AID and MDD showed significant association with a lifetime suicide attempt (AOR = 6.86, p < 0.001) and showed stronger association with multiple attempts (AOR = 10.38, p < 0.001).Conclusion: AID was associated with suicide attempt and impulsivity, and the both AID and MDD showed much stronger association with lifetime suicide attempt and multiple attempts.

Highlights • An anxiety attack means "a sudden attack of fear or intense anxiety". • Many people experienced anxiety attacks even without life-threatening situations. • Anxiety attacks were relevant to an increased suicide risk, especially without life-threatening situations and with comorbid MDD. Abstract Regardless of categorical diagnosis, many psychiatric patients suffer from sudden attack of fear or intense anxiety. In this study, we defined anxiety attacks to refer to these phenomena and investigated their association with depression and suicide attempts. A total of 12,532 adults randomly selected population through the one-person-per-household method completed a face-to-face interview using the Korean version of Composite International Diagnostic Interview (K-CIDI). A total of 5.88% reported to have experienced anxiety attacks. Among them, 46.5% reported to have experienced anxiety attacks without life-threatening situations. 'Anxiety attacks' group reported more suicidal ideation, plan, and attempts, which were even higher frequencies in 'anxiety attacks without life-threatening situations' group than 'anxiety attacks only with life-threatening situations' group and showed stronger association with lifetime suicide attempts when it had comorbid major depressive disorder (MDD) (AOR = 9.69, 95%CI 5.90–15.90), compared with 'never' group. There was no association between each symptom of patients with anxiety attacks and their lifetime suicide attempt. In conclusion, the finding suggests that there are as many individuals who experience anxiety attacks without life-threatening situations as those with life-threatening situations. And anxiety attacks appear to be relevant to an increased risk of suicide attempt, especially without life-threatening situations and with comorbid MDD. [ABSTRACT FROM AUTHOR]
