Interpersonal relationships and suicidal ideation among Chinese youths: A network analysis

BackgroundSuicidal ideation is a noteworthy health problem that requires further study in the field of interpersonal relationships. The main scope of relationships include family, teachers, peers, and the Internet. However, few studies have considered the effects of interpersonal interactions. Based on the Interpersonal Theory of Suicide, this study explores the relation between different interpersonal relationships and suicidal ideation. MethodsA network analysis approach was used to test the relationships. Cross-sectional data (N = 1694; 52.1 % boys; Mage = 11.86 years, SD = 1.59) were collected from primary and secondary students in October–November 2022. Participants completed a survey including demographic part and questionnaires: Positive and Negative Suicide Ideation Inventory (PANSI), Interpersonal Needs Questionnaire (INQ), Family Adaptability and Cohesion Evaluation Scale (FACES II), Inventory of Parent and Peer Attachment (IPPA), Student-Teacher Relationship Scale (STRS) and Facebook Intensity Scale (FIS). ResultsAll variables showed a significant correlation in this inferred network. Family, teacher-student, and peer relationships are protective against suicidal ideation. The closeness of the teacher-student relationship showed the highest strength centrality. However, online interpersonal relationship is a risk factor for suicide. Thwarted belongingness and perceived burdensomeness are proximal factors of suicidal ideation that influenced all interpersonal relationships. LimitationsThe network analysis as a data-driven and exploratory method may be limited to provide exact cause and effect relationship. ConclusionsThis study shows that teacher-student connections may be more important than other relationships of young people. Improper peer and online interpersonal relationship could be risky for suicide. Further studies are needed to examine the role of these relationships elaborately.

Presenting a Causal Model of Suicidal Behavior Based on Early Childhood Trauma the Mediation of Thwarted Belongingness in Suicide Attempters in Tehran

Objective: According to reports, a suicide attempt is made every 40 seconds in the world, some of which have serious consequences for the attempter. The present study investigated the relationship between suicidal behavior in suicide attempters and early childhood trauma, with the mediation of thwarted belongingness. Materials and Methods: The current study is descriptive and correlational. A total of 365 patients who attempted suicide and were hospitalized at Baharloo Hospital in Tehran in 2022 were selected through convenience sampling. The Childhood Trauma Questionnaire (CTQ), Interpersonal Needs Questionnaire (INQ) for thwarted belongingness, and the Suicidal Behaviors Questionnaire-Revised (SBQ-R) were administered to the suicide attempters. The Sobel test was used to examine the mediation hypotheses, and structural equation modeling (SEM) was employed to evaluate the proposed model. Findings: The results showed that there are positive and significant relationships between Childhood trauma score and suicidal behavior (r=0.42, p<0.001), and thwarted belongingness and suicidal behavior (r=0.395, p<0.001). The model fit indices confirmed the path from Childhood trauma to suicidal behavior and the path from Childhood trauma with the mediation of thwarted belongingness. Conclusion: The results of this study showed that Childhood trauma plays a crucial role in suicidal behavior, both directly and indirectly through the mediation of thwarted belongingness. Therefore, teaching families and schools to prevent childhood traumas, as well as providing treatment for individuals with childhood traumas and addressing their interpersonal needs (thwarted belongingness), can effectively prevent and reduce suicidal behavior.

Understanding suicidal ideation-a network analysis of the Interpersonal Needs Questionnaire.

Identifying various interacting risk factors for suicidality is important to develop preventive measures. The Interpersonal-Psychological Theory of Suicidal Behavior (IPTS) postulates suicidal ideation resulting from the occurrence of Perceived Burdensomeness (PB) and Thwarted Belongingness (TB). Suicidal behavior ultimately occurs if people have a Capability for Suicide. In past studies, the validity of TB was often not empirically confirmed, questioning which of the aspects of TB are central and related to suicidal ideation and whether applied measurement methods adequately capture the construct. Using a sample of 3,404 individuals from different clinical and nonclinical settings, 30% (1,023) of whom reported suicidal ideation, two network analyses were conducted on the Interpersonal Needs Questionnaire (INQ) and a variable mapping suicidal ideation. Analyses revealed that some items of the INQ were not related to suicidal ideation and the most central items did not have the strongest associations to suicidal ideation. Based on these results, a shortened version of the INQ with the four items that showed the strongest associations with suicidal ideation in the network analyses was suggested.

50 Neuropsychological Functioning in Depression, Borderline Personality Disorder, and Suicidality

Objective:Depression and borderline personality disorder (BPD) are frequently comorbid psychiatric disorders that reliably share deficits in executive functioning (EF). In addition to EF, meta-analytic evidence indicates that processing speed and verbal memory are also affected in depression and BPD, but the impact of BPD further spans the domains of attention, nonverbal memory, and visuospatial abilities. Suicidality is a notable phenotypic commonality in depression and BPD. Neuropsychologically, there are consistent discrepancies between individuals who have and have not thought about suicide in global cognitive functioning, as well as between those who have attempted suicide and those who have just thought about suicide in EF. This study aims to replicate the effect size differences between these groups and explore whether neuropsychological functioning relates to dimensional measures of psychopathology.Participants and Methods:Right-handed women between the ages of 18 and 55 were recruited into one of three diagnostic groups: a) current major depressive episode (MDD; n=22); b) current major depressive episode with comorbid BPD (MDD+BPD; n=19); and c) absence of current major depressive episode and BPD (controls; n=20). Groups were also classified based on historical suicide attempt and on the presence or absence of historical suicidal ideation. Exclusions included bipolar disorder, neurodevelopmental disorder, moderate/severe brain injury, neurological illness, serious physical illness, eating disorder, and moderate/severe alcohol/substance use disorder. Participants were administered the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD), Beck Depression Inventory (BDI-II), Interpersonal Needs Questionnaire (INQ), UPPS-P Impulsive Behavior Scale, Everyday Memory Questionnaire, Brief Visuospatial Memory Test (BVMT), California Verbal Learning Test (CVLT), Delis-Kaplan Executive Function System (D-KEFS) Color-Word Interference Test, D-KEFS Trail Making Test, D-KEFS Verbal Fluency, Wechsler Adult Intelligence Scale-IV Coding and Digit Span subtests, Wechsler Memory Scale-IV Logical Memory, and Wechsler Test of Adult Reading.Results:With one exception, analyses of raw scores indicated there were no significant neuropsychological differences between groups based on diagnosis, historical suicidal ideation, and suicide attempt (p>.05). However, individuals with MDD+BPD, historical suicidal ideation, or suicide attempt endorsed more memory complaints than the other groups with large effect size differences. Differences in self-reported impulsivity indicated large effects between controls and MDD+BPD, moderate to large effects when comparing controls to MDD and MDD to MDD+BPD, and moderate effects among the suicidal ideation and suicide attempt groups. Impulsivity was rated highest in those with MDD+BPD, historical suicidal ideation, or suicide attempt. These analyses applied false-discovery rate correction and adjusted for age. Using ridge regressions to separately predict depressive symptoms, BPD symptoms, and suicide risk factors, neuropsychological indices were most associated with suicide risk factors and explained 22.8% of INQ variance. Conversely, these indices explained 9.6% of ZAN-BPD variance and 0.6% of BDI-II variance.Conclusions:The neuropsychological literature on BPD describes moderate crosscutting neuropsychological dysfunction, and clarifying the distinct cognitive alterations associated with comorbid psychiatric disorders and suicide phenomena offers novel avenues of research for investigating their mechanisms. While neuropsychological functioning may not strongly relate to psychiatric symptomatology, it may contribute to meaningful algorithms of suicide risk in individuals with depression and BPD.

Suisid düşüncelerinde sosyal medya kullanımı ve kişilerarası faktörlerin önemi

Aims: Every year, more than 800. 000 individuals die by suicide as a global public health issue In our study, we aimed to evaluate the relationship between suicidal ideation and interpersonal needs, acquired suicidal efficacy, and social media use in the context of Psychological Suicide Theory. 
 
 Methods: This cross-sectional study was conducted with 450 individuals. Participants were contacted through online platforms (Whatsapp and e-mail). The sociodemographic form (gender, age, education, income level, which social media platforms they prefer, their daily social media usage time, what kind of news they follow on social media), Interpersonal Needs Questionnaire (INQ), Acquired Suicide Capability – Fear of Death Scale, (ACSS-FAD), Beck Hopelessness Scale (BHS) and Social Media Use Scale were applied to the volunteers who gave consent to participate in the study. The research was approved by the Kırıkkale University Faculty of Medicine Non-Interventional Research Ethics Committee. 
 
 Results: A total of 450 individuals, 308 (68.4%) women and 142 (31.6%) men, participated in the study, with an average age of 26.19± 7.81. 9.3% (n=42) of the participants had a history of suicide attempt. It was learned that 50.7% of the participants drew their attention to the news of suicide on social media, and 22.4% of them followed the news of suicide. it was observed that those who had suicide attempts had significantly higher scores on the SMUIS and INQ (p= 0.002, p= 0.000). Those who followed suicide news on social media were found to have substantially higher SMUIS, INQ, and ACSS-FAD scores (p= 0.000, p= 0.000, p= 0.029). Hierarchical regression analysis was utilized to evaluate factors assumed to have an effect on acquired suicidal efficacy. According to this; social media use was found to be effective on acquired suicide capability- death fearlessness (β=.295, t(450)=6.01, p

Spanish Validation of the Interpersonal Needs Questionnaire and the Acquired Capability for Suicide Scale Among Mexican University Students.

the rate of death by suicide has increased in Mexico, representing a significant public health problem. To prevent and treat this phenomenon, it is crucial to identify reliable suicide risk factors among Mexicans. The Interpersonal Theory of Suicide has demonstrated empirical support for the role of thwarted belongingness, perceived burdensomeness, and acquired capability in the development of suicidal desire and behaviors. The measure of the theory's constructs-the Interpersonal Needs Questionnaire (INQ) and the Acquired Capability for Suicide Scale (ACSS)-has also shown good psychometric qualities. translate, culturally adapt and validate these instruments. 495 university students from Mexico City participated in two independent samples (n = 239; n = 256). For the INQ, the available version in Spanish was used. For the ACSS, the most current version in English was used. Based on the results from the first sample, items were modified, eliminated, or added for the second sample. the INQ demonstrated good fit (RMSEA = .054, TLI = .97, IFI = .97, NFI = .95) with an internal consistency of .77 and .87 for thwarted belongingness and perceived burdensomeness, respectively. The ACSS obtained similar results (RMSEA = .011, CFI = .99, TLI = .99, IFI = .99, NFI = .91); the internal consistency was .77. the Spanish version of the instruments display good psychometric properties and can be used to measure the constructs of the interpersonal theory of suicide. However, further replication is needed to support generalizability in other Spanish-speaking populations.

Autistic traits and self-harm in adolescents: a study on interpersonal psychological theory of suicide

BackgroundThe purpose of the study was to investigate whether autistic traits predicted the presence and recurrence of self-harm and to determine any relationship mediated by the Interpersonal Psychological Theory of Suicide (IPTS), which composed of the social influence of negative life experiences on suicide, is referred to as "acquired capability", while proximal social risk factors are referred to as "thwarted belonging and perceived burdensomeness."ResultsWe evaluated any interaction with the Autistic Quotient (AQ) score and self-harm whether it was explained by the thwarted belonging/perceived burdensomeness in the Interpersonal Needs Questionnaire (INQ), victimization in the Olweus Bully/Victim Questionnaire (OBVQ), and maltreatment in the Childhood Trauma Questionnaire (CTQ). Communication and social skill as autistic traits predicted the presence of self-harm, yet the association vanished after including thwarted belonging and perceived burdensomeness, which are independent predictors of the presence of self-harm. Social skill and the sum score of autistic traits predicted the recurrence of self-harm, and the prediction was mediated largely by thwarted belonging and much less by perceived burdensomeness.ConclusionsThe unique interaction of autistic traits and IPTS increases the risk of self-harm. Within autistic traits, social skills, in particular, are likely associated to attempts at self-harm through acquired capability. The results of this research were identified as attention to loneliness and social support may be helpful in reducing self-harm in adolescents with autistic traits.

Demoralization in Schizophrenia: A Pathway to Suicidal Ideation?

Introduction: Individuals with schizophrenia are at increased risk for suicide, and the Demoralization Hypothesis states that non-delusional awareness of one’s social, cognitive, or occupational deterioration elicits depression and hopelessness. Both depression and hopelessness are established risk factors for suicide and are features of schizophrenia. The present study investigated whether insight into one’s schizophrenia yields suicidal ideation, specifically by way of thwarted belongingness and perceived burdensomeness, which are constructs related to demoralization and measured by the Interpersonal Needs Questionnaire (INQ). Methods: Three separate models explored the mediating role of INQ scores on suicidal ideation in 99 participants with schizophrenia. With suicidal ideation entered as the dependent variable and INQ scores entered as the mediator, the first model included insight as the independent variable, the second included cognitive functioning, and the third included cognitive deterioration post-illness-onset. Results: Consistent with our hypothesis, INQ scores related to suicidal ideation (B = .03, SE = .01, p < .001). However, neither insight, cognitive functioning, nor cognitive deterioration predicted INQ scores or suicidal ideation. Additionally, INQ scores did not mediate relationships with suicidal, ideation. Conclusion: Although INQ scores led to increased suicidal ideation, neither insight into illness, current cognitive functioning, nor shift in functioning led to increased INQ scores. Implications are discussed, and future directions are proposed.

Negative Urgency, (Lack of) Premeditation, and Sensation Seeking: Indirect Relationships with Suicidal Ideation through Thwarted Interpersonal Needs

Objective Differences in how impulsivity is conceptualized, along with a myopic focus on impulsivity’s relationship with historical suicidal behaviors, have resulted in limited implications made from prior research regarding impulsivity and suicidal thoughts and behaviors. The current study investigated the indirect effect facets of impulsivity may have on suicidal ideation, specifically, through thwarted interpersonal needs. Methods Participants were N = 424 undergraduate students who completed a cross-sectional survey. Participants completed the Urgency, Premeditation, Perseverance, Sensation Seeking, Impulsive Behavior Scale (UPPS), the Adult Suicide Ideation Questionnaire (ASIQ), and the Interpersonal Needs Questionnaire (INQ). Parallel mediation models were run to examine the relation between facets of impulsivity, perceived burdensomeness, thwarted belongingness, and suicidal ideation. Results Thwarted belonginess and perceived burdensomeness significantly accounted for the variance in the relation between negative urgency and suicidal ideation. Neither thwarted belongingness nor perceived burdensomeness significantly explained variance in the relation between (lack of) premeditation and suicidal ideation. Conversely, perceived burdensomeness and thwarted belonginess significantly explained the inverse relation between sensation seeking and suicidal ideation (i.e., greater sensation seeking was related to lower perceived burdensomeness and thwarted belongingness and in turn lower suicidal ideation). Conclusion Negative urgency, in particular, is related to suicidal ideation through thwarted interpersonal needs. Future research should continue to differentiate between various types of impulsivity and its relationship with both suicidal ideation and behaviors utilizing both cross-sectional and ambulatory assessments of these constructs. HIGHLIGHTS Negative urgency is related to suicidal ideation. Negative urgency is related to thwarted interpersonal needs. Thwarted interpersonal needs partially explain the relation between negative urgency and suicidal ideation.

Development of a suicidal tendency model in borderline personality disorder patients based on perceived burden and suicidal acquisition capacity through pessimistic attribution style

Background and Aim: Borderline personality disorder is specifically separated from other mental disorders by its emphasis on successful suicide, non-suicidal self-injurious behaviors, and suicidal behavior as a diagnostic criterion. Therefore, the present study aimed to develop a model for suicide tendency in individuals with borderline personality disorder based on perceived burdensomeness and acquired capability for suicide through the use of deceitful documents. Methods: The research method was of correlation type with structural relationship path analysis plan, or modeling. The statistical population of the current study included all female and male adults aged 18 to 40 who referred to the psychiatric department of hospitals and psychiatric offices in Tehran during the year 2021, who received a diagnosis of borderline personality disorder and had a history of attempted suicide, suicidal tendencies, and There were suicidal thoughts. Sample get the method It was done purposefully through the screening of patients. The sample size was equal to 500 people, which was chosen according to Kline's theory to design structural equations. In this research, Beck's (1961) suicidal ideation questionnaires, suicidal behavior capacity (revised) by Osman et al. (2001), and Patterson et al.'s (1981) documentary styles and perceived burden with Interpersonal Needs Questionnaire (INQ) were measured. Data analysis in SPSS software AMOS It was done using the structural equation modeling method. Results: The results showed that the proposed research model had an acceptable fit. Therefore, the research model based on modeling the relationship between perceived burden and the acquired capacity of suicide with the desire to commit suicide through pessimistic attribution style was confirmed by using structural equation analysis. Also, the secondary results showed that there is a significant correlation between the predictor variables of the research with the tendency to commit suicide. In this way, the effect of perceived burden and acquired capacity of suicide with pessimistic attribution style was 0.25 and 0.30 respectively, which increased to 0.46 due to the facilitating role of pessimistic attribution style. Conclusion: Based on this, it can be concluded that the positive effect of the perceived burden and the acquired capacity of suicide on the desire to commit suicide is increased and facilitated by the style of pessimistic attributions. According to this result, the mediating role of pessimistic attributional style to facilitate the positive effect of predictor variables (perceived burden, and acquired suicidal capacity) on suicidal tendency in patients with borderline personality disorder was confirmed. This result indicates the possibility of combining Abramson's cognitive theory and Joyner's interpersonal relationships in explaining suicidal tendencies.

Measurement invariance of the Interpersonal Needs Questionnaire (INQ-15) across sexual orientation, gender identity, and race/ethnicity in a sample of sexual minority young adults.

Sexual minority (e.g., gay, lesbian, bisexual) people are at increased risk for suicidal thoughts and behaviors compared to their heterosexual peers. The interpersonal theory of suicide proposes that perceived burdensomeness and thwarted belongingness are central to the desire to die, and both are associated with suicidal ideation in sexual minority samples. The Interpersonal Needs Questionnaire (INQ) was developed to measure these risk factors and has become the most commonly used measure. However, it is unknown whether the INQ demonstrates similar measurement properties across subgroups of sexual minority people. Therefore, the goal of this study was to examine whether the 15-item version of the INQ exhibited measurement invariance (MI) across sexual orientation (gay/lesbian vs. bi +), gender identity (cisgender men vs. cisgender women vs. transgender/gender diverse individuals), and race/ethnicity (non-Latinx White individuals vs. people of color) in a sample of 792 sexual minority young adults (ages 18-29). A series of multigroup measurement invariance models indicated that the INQ-15 met strict invariance (i.e., equal factor loadings, item intercepts, and residual variances) across all three dimensions of identity. This indicates that it can be used and compared across diverse samples of sexual minority young adults. Results also indicated that perceived burdensomeness was greater for transgender/gender diverse individuals than for cisgender men and women, and that perceived burdensomeness and thwarted belongingness were greater for people of color than for non-Latinx White individuals. In contrast, gay/lesbian and bi + individuals did not differ. Additional research is needed to understand the factors that account for these group differences.

Development and initial validation of a parent report measure of youth belongingness and burdensomeness.

The Interpersonal Theory of Suicide (ITS) implicates thwarted belongingness and perceived burdensomeness as casually related to suicide desire. The self-report Interpersonal Needs Questionnaire (INQ) is the most commonly used measure to assess belongingness and burdensomeness, including in youth. No parent-report version of the INQ exists. The current study adapted the ten-item version of the INQ (INQ-10) for parent report of youth belongingness and burdensomeness, thereby moving ITS research in youth to a multi-informant measurement approach, and examined its factor structure and convergent and concurrent validity. Participants were 168 clinic-referred youths ages 9-17years (58.9% female; Mage =11.91) and their parents. Findings supported a two-factor structure of the parent INQ. In support of convergent and concurrent validity, parent-reported belongingness and burdensomeness were significantly associated with youth-reported belongingness and burdensomeness, suicide ideation, anxiety symptoms, depressive symptoms, and impairment. The current study provides initial support the INQ-parent version as a valid measure to complement youth self-reports of belongingness and burdensomeness.

Perceived Burdensomeness, Thwarted Belongingness, and Social Exclusion in Transgender Women: Psychometric Properties of the Interpersonal Needs Questionnaire.

Transgender women (TGW) experience serious psychiatric problems and high suicide rates. According to the interpersonal theory of suicide, thwarted belongingness and perceived burdensomeness play major roles in suicidality and can be measured by the Interpersonal Needs Questionnaire (INQ). However, no study has validated the use of the INQ in TGW. This study aimed to examine the psychometric properties of the INQ among TGW. We recruited 198 TGW (mean age 38.47 years) from Shenyang, China, using snowball sampling. The construct validity of the INQ was assessed through factor analysis, and convergent and divergent validity were examined through a structural equation model with other psychosocial factors. The construct validation analysis supported a three-factor model (perceived burdensomeness, thwarted belongingness, and social exclusion) with satisfactory fit indices: χ2/df = 1.54, RMSEA = 0.052, CFI = 0.931, TLI = 0.916, SRMR = 0.053. The thwarted belongingness was significantly associated with self-esteem and social support, and the social exclusion was significantly associated with loneliness, depression, entrapment, and defeat, suggesting satisfactory convergent and divergent validity for the three-factor model. The present findings indicate that for TGW, high social exclusion is important in assessing perceived interpersonal needs, while the notable deviation from previous two-factor model warrants further study.

Toward Understanding of Suicidality in a Spanish Clinical Population: Validation of the European Spanish Version of the Interpersonal Needs Questionnaire

Introduction: Suicidal ideation (SI) represents one of the most prominent predictors of suicidal behavior (SB). The Interpersonal Needs Questionnaire (INQ) was developed from the Interpersonal Theory of Suicide (ITS) to assess the 2 core drivers of SI proposed by the theory. Despite the relevance of suicide-related ideations and ITS, there is a lack of psychometric measures validated in clinical Spanish population that adequately evaluate SI components of ITS. Thus, the main aim of the study was to validate INQ-10 in a Spanish clinical sample including the genuine cultural and linguistic characteristics of European Spanish. Methods: 315 participants were included in the analyses; 149 of them consulted mental health services for the presence of suicide-related behaviors. A series of exploratory and confirmatory factor analyses were carried out to identify the factor solution. Bivariate and multivariate analyses were used to analyze psychometric properties. Finally, sensitivity and specificity properties were explored through receiver-operating characteristic analyses which also provided the cut-off values of the questionnaire. Results: An 8-item version demonstrated a good fit to the 2-factor solution. Likewise, this 8-item version showed good psychometric properties. Sensitivity and specificity indices of the version validated as well as the calculated cut-off points were excellent. Conclusions: The current results demonstrate the utility of an 8-item INQ European Spanish version as a valid measure of the current SI in Spanish clinical population. In addition, the validated form reflects the theoretical framework on which it was built.

The Interpersonal-Psychological Theory of Suicide in Medical Students: Comparisons of Individuals without Suicidality, Ideators, and Planners.

The aim of this study was to explore the interpersonal–psychological theory of suicide (IPTS) in medical students. Higher levels of thwarted belongingness and perceived burdensomeness were expected in medical students with suicidality compared with medical students without suicidality, and a high level of acquired capability was expected in planners compared with ideators. Recruited for the study were 178 undergraduate medical students at the Université Libre de Bruxelles (ULB): 95 subjects without suicidality, 24 subjects with lifetime suicidality, 28 subjects with recent suicidal ideation, and 26 planners. An ad hoc questionnaire evaluated the risk of suicide as well as the “Suicidal thoughts and wishes” item of the BDI-II. The Interpersonal Needs Questionnaire (INS) measured thwarted belongingness (TB) and perceived burdensomeness (PB). The Acquired Capability for Suicide Scale (ACSS) measured notably fearlessness of death or pain tolerance and depression was rated using the revised version of the Beck Depression Inventory (BDI). Cognitive–affective symptoms of depression (CA-BDI) were assessed using six items of the BDI. Analyses of variance showed significant differences between groups for TB and PB but not for ACSS. Analyses of covariance, controlling for the CA-BDI scores, confirmed the significance of differences in TB and PB. Post hoc tests showed that (1) high levels of TB were characteristic of subjects with recent suicidal ideation and planners compared with subjects without suicidality; and (2) high levels of PB were characteristic of planners compared with the three other groups. Among the three characteristics of the IPTS, PB could be a strong predictor of severe suicide risk in medical students.

Examining psychometric properties of the Interpersonal Needs Questionnaire among college students in India.

With the second-highest population in the world, suicide-related deaths in India are high, and adults under 30 are particularly at an increased risk. However, empirical examinations of factors contributing to suicide in India and assessments of reliability and validity of self-report measures assessing these constructs are rare. The present study examined the psychometric properties of the Interpersonal Needs Questionnaire (INQ). Undergraduate students in India (N=432) completed the INQ and questionnaires assessing suicidal ideation, depression, fearlessness about death, and pain tolerance. Confirmatory factor analyses of the 15-item INQ indicated that after removing three items assessing perceived burdensomeness, the two-factor structure of INQ demonstrated acceptable fit with good internal consistency for each of the subscales (α=.84-.90). In line with the interpersonal-psychological theory of suicidal behavior (IPTS), thwarted belongingness and perceived burdensomeness interacted to predict suicidal ideation. Additionally, these constructs were positively associated with suicidal ideation and depression, and weakly correlated with fearlessness about death and pain tolerance. Results support the relevance of the IPTS for understanding suicidal ideation among college students in India. The results suggest that modified INQ demonstrates strong internal consistency, as well as good construct, criterion, and discriminant validity among Indian college students.

Psychometric Properties of Interpersonal Needs Questionnaire-15 for Predicting Suicidal Ideation among Migrant Industrial Workers in China.

Objective: Interpersonal theories of suicide suggest that the Interpersonal Needs Questionnaire (INQ) can be used to measure suicidal ideation, but few studies have focused on migrant people, a group with a high prevalence of suicidal ideation. The aim of this study was to validate the psychometric properties of the INQ-15 and its prediction of suicidal ideation among migrant industrial workers in China. Method: A stratified multi-stage sample of 2023 industrial workers was recruited from 16 factories in Shenzhen, China. There were 1805 nonlocal workers, which we defined as migrant workers with a mean age of 32.50 ± 8.43 years old who were 67.3% male. The structure of the Chinese version of the INQ-15 and its correlation and predictive utility for suicidal ideation were examined through factor analysis, the Item Response Theory, the M2 test, logistic regression, and receiver operating characteristic (ROC) analysis. Results: Different from studies among various samples in which a two-factor solution is identified, results within this sample indicated three factors: perceived burdensomeness, thwarted belongingness, and social isolation. The model fit statistics of three-factor INQ were 0.075 for RMSEA, 0.945 for CFI, 0.932 for TLI, and 0.067 for SRMR. The model standard estimated factor loadings ranged from 0.366 to 0.869. The summed scores of INQ and perceived burdensomeness predicted suicidal ideation after controlling for sociodemographic characteristics such as age, gender, and income with AUC of 0.733 (95% CI: 0.712/0.754) and 0.786 (95% CI: 0.766/0.804). In the meantime, the comparison of the predictive ability between INQ total scores and PB scores was significant with p < 0.05. Conclusion: The INQ has good psychometric properties and can be used to assess how migrant workers living in the Shenzhen perceive meeting interpersonal psychological needs and shows good predictive ability of suicidal ideation. Perceived burdensomeness appears to play a role in suicide and may be a point of intervention, yet the notable deviation from previous findings and the relative weakness of two of the other factors warrant further study.

Comparison of Psychometric Characteristics for Five Versions of the Interpersonal Needs Questionnaire in Teenagers Sample.

Interpersonal Needs Questionnaire (INQ) is a self-report measure of perceived burdensomeness and thwarted belongingness with five versions in recent studies. There are five versions of INQ. But results from studies using different versions are quite different. Current suicide behavior among teenagers has attracted much attention. But which version is more suitable for teenage samples is still uncertain. It is important to compare the potential differences in different versions of INQ to identify the most psychometrically available version to predict teenagers' acquired capability for suicide and provide them with timely help to reduce teenagers' suicide rates. This study compared the construct validity, internal consistency, validity, and average test information of each version in the sample of teenagers. Results showed the 10-item version provided the most average test information in both thwarted belongingness subscale and perceived burdensomeness subscale, and the INQ-10 is more suitable for teenage samples.

Chinese versions of the Interpersonal Needs Questionnaire: Psychometric properties, measurement invariance across gender and cultures.

Associations between unmet interpersonal needs and different aspects of suicide have been observed in both Western and non-Western cultures using the Interpersonal Needs Questionnaire (INQ). However, measurement invariance is a prerequisite for comparing differences between culturally different groups, and to date, no studies have examined measurement invariance of INQ across cultures. This study aimed to (a) validate Chinese versions of the INQ, (b) assess measurement invariance across gender for the Chinese INQ, (c) assess measurement invariance across Australian and Chinese cultures for the INQ, and (d) comprehensively assess the association of interpersonal needs with suicide ideation. A sample of 469 Australian undergraduates and a sample of 854 Chinese undergraduates were used in this study. For testing measurement invariance across gender, the sample of Chinese undergraduates was split by gender into the Chinese male and Chinese female samples. Five versions of INQ (10-, 12-, 15-, 18- and 25-item) were tested. The 10- and 15-item Chinese INQ demonstrated adequate psychometric properties through various analyses (i.e., reliability, confirmatory factor analysis, and structural equation modeling) and also demonstrated measurement invariance across gender via multigroup confirmatory factor analysis. The 10-item INQ demonstrated measurement invariance across Australian and Chinese cultures. Of the two interpersonal factors, only perceived burdensomeness was significantly associated with suicide ideation. Multigroup structural equation modeling demonstrated that perceived burdensomeness may be a greater risk factor of suicide among Australian undergraduates than among Chinese undergraduates. Practical and theoretical contributions of this study are discussed.

Comfort Expressing Emotions and Suicide Ideation: Evidence of Indirect Effects Via Perceived Burdensomeness and Thwarted Belongingness

Objective Emotion regulation strategies and related constructs have been implicated both as risk and protective factors in a range of mental health outcomes among young adults. To expand upon this previous research, we examined comfort expressing four discrete emotions (i.e., love, happiness, sadness, and anger) as factors that protect against suicide ideation in young adults, within the context of the interpersonal theory of suicide. Method The sample consisted of 449 college students (73.1% female, 70.6% Hispanic, Mage = 20.5 years) taking part in a larger study of mood and well-being. Students were recruited from a psychology participant pool and completed self-report measures at a single time point for course credit. Comfort expressing emotions and suicide ideation were assessed using the Measure of Verbally Expressed Emotion (MoVEE) and Adult Suicidal Ideation Questionnaire (ASIQ), respectively. Perceived burdensomeness and thwarted belongingness were assessed using the Interpersonal Needs Questionnaire (INQ). Results Preliminary analyses revealed negative associations between comfort expressing all four emotions and suicide ideation (rs = −.13 to −.26). Results from structural equation modeling supported indirect effects from comfort expressing happiness and sadness to suicide ideation, via perceived burdensomeness and thwarted belongingness. An indirect effect was also identified from comfort expressing love to suicide ideation, via thwarted belongingness. Conclusions Results suggest that comfort expressing emotions (particularly sadness and happiness) is a protective factor against suicide ideation for young adults. These findings suggest that suicide-prevention efforts may wish to focus on increasing comfort expressing emotions to trusted support networks as potential intervention targets. HIGHLIGHTS Comfort expressing emotions is negatively associated with suicide ideation. Comfort expressing emotions is associated with belongingness and burdensomeness. Comfort expressing emotions may be a potential target for suicide prevention.
