Utility of Single Items within the Suicidal Behaviors Questionnaire-Revised (SBQ-R): A Bayesian Network Approach and Relative Importance Analysis.

The Suicidal Behaviors Questionnaire-Revised (SBQ-R) comprises four content-specific items widely used to assess the history of suicide-related thoughts, plans or attempts, frequency of suicidal ideation, communication of intent to die by suicide and self-reported likelihood of a suicide attempt. Each item focuses on a specific parameter of the suicide-related thoughts and behaviors construct. Past research has primarily focused on the total score. This study used Bayesian network modeling and relative importance analyses on SBQ-R data from 1160 U.S. and 1141 Chinese undergraduate students. The Bayesian network analysis results showed that Item 1 is suitable for identifying other parameters of the suicide-related thoughts and behaviors construct. The results of the relative importance analysis further highlighted the relevancy of each SBQ-R item score when examining evidence for suicide-related thoughts and behaviors. These findings provided empirical support for using the SBQ-R item scores to understand the performances of different suicide-related behavior parameters. Further, they demonstrated the potential value of examining individual item-level responses to offer clinically meaningful insights. To conclude, the SBQ-R allows for the evaluation of each critical suicide-related thought and behavior parameter and the overall suicide risk.

Associations among Distress Rumination, Somatic Anxiety, and Suicidal Ideation in Chinese College Students - Shandong Province, China, 2019-2020.

What is already known about this topic?: The literature has consistently demonstrated that distress rumination following a traumatic event has significant implications for mental health. However, the potential association between distress rumination and suicidality, as well as the underlying mechanisms driving this relationship, remains to be elucidated. What is added by this report?: The current study demonstrated a significant, positive correlation between distress rumination and suicidal ideation in college students who have encountered traumatic events. The findings indicate that somatic anxiety serves as a mediator between distress rumination and suicidal ideation. What are the implications for public health practice?: Interventions aimed at reducing somatic anxiety may contribute to a decrease in suicidal ideation. Assessing and addressing somatic anxiety symptoms in college students experiencing distressful rumination following traumatic events could potentially lower the risk of suicide.

Item Response Theory and Differential Item Functioning Analyses With the Suicidal Behaviors Questionnaire-Revised in US and Chinese Samples.

Background: Despite the widespread use of the Suicidal Behaviors Questionnaire-Revised (SBQ-R) and advances in item response theory (IRT) modeling, item-level analysis with the SBQ-R has been minimal. Aims: This study extended IRT modeling strategies to examine the response parameters and potential differential item functioning (DIF) of the individual SBQ-R items in samples of US (N = 320) and Chinese (N = 298) undergraduate students. Method: Responses to the items were calibrated using the unidimensional graded response IRT model. Goodness-of-fit, item parameters, and DIF were evaluated. Results: The unidimensional graded response IRT model provided a good fit to the sample data. Results showed that the SBQ-R items had various item discrimination parameters and item severity parameters. Also, each SBQ-R item functioned similarly between the US and Chinese respondents. In particular, Item 1 (history of attempts) demonstrated high discrimination and severity of suicide-related thoughts and behaviors (STBs). Limitations: The use of cross-sectional data from convenience samples of undergraduate students could be considered a major limitation. Conclusion: The findings from the IRT analysis provided empirical support that each SBQ-R item taps into STBs and that scores for Item 1 can be used for screening purposes.

Optimizing the Beck Scale for Suicide Ideation: An Item Response Theory Approach Among U.S. Military Personnel.

The Beck Scale for Suicide Ideation (BSS) is one of the most used and empirically supported suicide risk assessment measures for behavioral health clinicians and researchers. However, the 19-item BSS is a relatively long measure and can take 5 to 10 minutes to administer. This study used Item Response Theory (IRT) techniques across two samples of mostly U.S. military service members to first identify (n1 = 1,899) and then validate (n2 = 757) an optimized set of the most informative BSS items. Results indicated that Items 1, 2, 4, 6, and 15 provided a similar-shaped test information curve across the same range of the latent trait as the full-length BSS and showed reliable item functioning across participant characteristics. The sum score of these five items showed a linear score linkage with the full-scale score, ρ > 0.87, and was equally as sensitive as the full scale for prospectively predicting near-term suicidal behavior at 74% with a cut score ≥1 (equivalent to full-scale score ≥6). Results are consistent with those from civilian samples. In time- or length-limited assessments, using these five BSS items may improve administration efficiency over the full BSS, while maintaining classification sensitivity.This study suggests that summing Items 1, 2, 4, 6, and 15 of the Beck Scale for Suicide Ideation (BSS) is an acceptable approach for shortening the full-length measure.

The Suicidal Behaviors Questionnaire-Revised (SBQ-R) and its Chinese version (C-SBQ-R): Further validity testing using the culture, comprehension, and translation bias procedure.

The Suicidal Behaviors Questionnaire-Revised (SBQ-R), a 4-item instrument for assessing and screening suicide-related thoughts and behaviors, has been translated into several different languages. In this study, we examined the psychometric properties of the SBQ-R and a new Chinese version of the instrument (C-SBQ-R) for college student samples. We used the culture, comprehension, and translation bias (CCT) procedure to examine the responses of independent Chinese college student samples who completed the C-SBQ-R (N1 = 298) and the SBQ-R (N2 = 292) and a U.S. college student sample (N3 = 320) who completed the SBQ-R. We found that the samples' C-SBQ-R and SBQ-R scale scores showed acceptable internal consistency reliability estimates, factor structures, and concurrent validity estimates. Measurement invariance was established across groups differing in (a) language but not culture, (b) culture but not language, and (c) both language and culture. Receiver operating characteristic curve analysis results showed that the cutoff score of 7 was similar for both the C-SBQ-R and the SBQ-R in screening for suicide-related thoughts and behaviors. Our findings provided empirical support that the psychometric properties of the C-SBQ-R and the SBQ-R are similar; both could be used to assess the suicide-related thoughts and behaviors constructs.

Religious affiliation and suicidality among college students in China: A cross-sectional study across six provinces.

BACKGROUND: Several past studies indicated that religious beliefs, orientation, and practice are protective of suicide. Findings from recent studies in China suggest that religiosity may contribute to increased suicidality. However, few studies have examined the associations between religious affiliation across different faiths and suicidality in China. OBJECTIVE: The current study examines the association between religious affiliation and suicidality among college students in six provinces in China. METHODS: We conducted a cross-sectional study involving 11,407 college students from six universities in Ningxia, Shandong, Shanghai, Jilin, Qinghai, and Shaanxi. We collected the data between October 2017 and March 2018 using self-report questionnaires. They included self-report measures of depression, psychache, hopelessness, self-esteem, social support, and life purpose. RESULTS: Participants with a Christian affiliation had 1.5 times (95% CI: 1.14, 1.99, p = 0.004) higher odds of indicating an elevated suicide risk, 3.1 times (95% CI: 1.90, 5.04, p<0.001) higher odds of indicating a previous suicide attempt, and increased overall suicidality (B = 0.105, p < 0.001) after accounting for demographic and risk/protective factors. Christians also scored the highest in depression, psychache, hopelessness, and the lowest social support, self-esteem, and purpose in life. Muslims reported decreased suicidality (B = -0.034, p = 0.031). Buddhism/Daoism yielded non-significant results in the multivariate analyses. CONCLUSIONS: Christian college students reported increased suicidality levels, perhaps due to public policies on religion. The decreased suicidality levels among Muslims may be attributed to higher perceived social support. The associations between religious affiliation and suicidality, depression, and hopelessness contrast sharply with US samples. This finding may be influenced by interactions between the religious denomination, individual, and social/political factors. This conclusion includes the possibility of anti-religious discrimination, which this paper did not investigate as a possible mediator and therefore remains a conjecture worthy of future investigation.

Psychological characteristics of suicide attempters among undergraduate college students in China: a cross-sectional study.

BACKGROUND: There is a need to understand the psychological characteristics of suicide attempters to prevent future suicide attempts. This study aims to examine potential differences between individuals who have attempted suicide and those who have not done so, on several risk and protective measures. METHOD: Participants were 11,806 undergraduate students from seven provinces in China, of which 237 reported a non-fatal suicide attempt. We used the random numbers generator function within the SPSS to randomly select a control subset of 1185 participants to be used as the comparison group based on a 1:5 case-control ratio. Scores on three commonly used risk measures (depression, hopelessness, and psychache) and three protective measures (social support, self-esteem, and purpose in life) for suicidality were adopted to compare the responses of the two groups. RESULTS: Suicide attempters had indicated higher Median scores for all three risk factor measurements. Suicide attempters also reported significantly lower Median scores for all three protective factor measurements compared to non-suicide attempters. The results suggest that the suicide attempters' group had higher risks of suicidality compared to the non-attempter group. CONCLUSIONS: Suicide attempters continued to report higher scores of risk factors and lower scores of protective factors, indicating that they may continue to be at a higher likelihood of a suicide attempt. Key protective factors should be identified for each individual in order to deliver appropriate clinical interventions to reduce their risk of reattempting.

The Reasons for Living Inventory for Young Adults (RFL-YA-II).

Suicide remains the second leading cause of death among young adults aged 15 years and older. Given its negative impact, it is essential to conduct studies that offer a greater understanding of the reasons young adults give for not engaging in suicide-related behaviors. The Reasons for Living Inventory for Young Adults is designed to explore this idea. This novel 24-item instrument measures four protective dimensions of reasons: Peer Acceptance and Support, Family Sources of Support, Faith-Related Support, and Personal Perceived Strength. The current investigations include two validation studies designed to examine further the psychometric properties of this instrument. Participants were undergraduate students at a state university in the U.S. Southwest. The first aim of the study was to evaluate the dimensionality of the instrument. We used confirmatory and bifactor confirmatory factor analyses to address this goal. The second aim was to examine the evidence for reliability estimates and concurrent validity. Results from both studies provided adequate support for a four-factor model across methods, acceptable internal consistency reliability, and concurrent validity for the dimensions of this instrument.Public Significance Statement: Suicide remains a significant mental health concern for young adults. The present studies found empirical support for the psychometric properties of a new measure for assessing four dimensions of the target construct: Peer-Acceptance and Social Support, Family Sources of Support, Faith-Related Support, and Personal Perceived Strength.

Using Contemporary Psychometric Methods to Construct and Validate Scores on a Short-Form Version of the Psychological Strain Scales.

BACKGROUND: The 40-item Psychological Strain Scales (PSS) was developed to measure four dimensions of psychological strains based on the Strain Theory of Suicide. Although the PSS has been increasingly used in recent years, the dimensionality and scoring of the PSS remained to be thoroughly examined using the Item Response Theory (IRT) approach. METHODS: Data came from a large sample of 11,412 Chinese undergraduate students. A bifactor-IRT model, specifying one general strain factor and four specific strains factors, was examined for fit to the sample data. A detailed item analysis, with analysis of the differential item functioning (DIF) of the items across gender, was undertaken to evaluate the dimensionality of the PSS. The associations among the PSS scale scores with scores on the concurrent measures, assessing psychache and suicidal behaviors, were examined. RESULTS: IRT-derived specific bifactor indices showed that the PSS was unidimensional, and thus the PSS total scores should be reported. Unidimensional subset of 5 items identified (Item 9, Item 12, Item 14, Item 16, and Item 20), using bifactor-IRT modeling and incremental validation, were selected to construct a potential short form of the PSS (PSS-SF). The PSS-SF scale scores demonstrated strong psychometric properties and associations with scores on the concurrent measures assessing relevant constructs. LIMITATIONS: This study used cross-sectional data from a non-clinical sample of Chinese undergraduate students. CONCLUSIONS: The PSS-SF should be considered as a unidimensional instrument with potential in enhancing our understanding and measurement of psychological strains with reduced response burden.

Evaluation of the psychometric properties of the Multidimensional Revenge Attitudes Inventory-21.

Despite a few hypothesized associations between revenge and suicide in the suicide literature, the potential of revenge as a multidimensional construct related to suicide has remained unexplored. Using data from undergraduate samples across 2 studies, we examined support for the psychometric properties and nomological network of scores on the Multidimensional Revenge Attitudes Inventory-21 (MRAI-21), a new self-report instrument composed of 3 dimensions: craving for revenge, revenge rumination, and suicide-related revenge. Results from Study 1 (N = 510), suggested that a 3-factor oblique solution obtained through contemporary factor analytic methods provided the best fit for the sample data. Estimates of internal consistency reliability for the MRAI-21 scale scores were above .90. In Study 2 (N = 380), we examined internal consistency reliability estimates for 6 concurrent self-report measures and conducted convergent validity analyses using latent variable modeling with scores on the MRAI-21 and concurrent measures. Results showed that scores on all instruments had adequate estimates of reliability and revealed a unique network of correlates for each of the MRAI-21 scale scores. Findings suggest that revenge can be measured as a multidimensional construct within the context of suicide; future directions and clinical implications are discussed.

Suicidality among Chinese college students: A cross-sectional study across seven provinces.

BACKGROUND: Although the suicide rate in China has decreased over the past 20 years, there have been reports that the younger age group has been experiencing an increased incidence of completed suicide. Given that undergraduate groups are at higher risks of suicidality, it is important to monitor and screen for risk factors for suicidal ideation and behaviors to ensure their well-being. OBJECTIVE: To examine the risk and protective factors contributing to suicidality among undergraduate college students in seven provinces in China. METHODS: We conducted a cross-sectional study involving 13,387 college students from seven universities in Ningxia, Shandong, Shanghai, Jilin, Qinghai, Shaanxi, and Xinjiang. Data were collected using self-report questionnaires. RESULTS: Higher scores in the psychological strain, depression, anxiety, stress, and psychache (psychological risk factors for suicidality) and lower scores in self-esteem and purpose in life (psychological protective factors against suicidality) were associated with increased suicidality among undergraduate students in China. Demographic factors which were associated with higher risks of suicidality were female gender, younger age, bad academic results, were an only child, non-participation in school associations, and had an urban household registration. Perceived good health was protective against suicidality. CONCLUSIONS: Knowing the common risk and protective factors for suicidality among Chinese undergraduate students is useful in developing interventions targeted at this population and to guide public health policies on suicide in China.

A comparison between American and Chinese college students on suicide-related behavior parameters / Comparación entre estudiantes universitarios estadounidenses y chinos en parámetros de comportamiento relacionados con el suicidio

BACKGROUND/OBJECTIVE: The United States (US) and China are the two largest economies, but recent and directly comparable studies on suicide-related behaviors in the two countries are lacking. By using the Suicidal Behaviors Questionnaire-Revised (SBQ-R), item-level comparison was performed in assessing self-reported suicide-related behaviors between the US and Chinese undergraduates. METHOD: This study involved a total of 3,185 college students aged between 18 to 24 years (1,185 US college students, and 2,000 Chinese students who were randomly selected from a large sample of 11,806 Chinese college students). Participants filled out the 4-item SBQ-R. RESULTS: Participants' responses were compared by country and sex. There was a higher overall risk of suicide-related behaviors among US students (24.3%) compared to Chinese students (17.0%). US students also reported higher lifetime attempt, past-year ideation, and lifetime threat. US female college students reported the highest suicide-related behaviors compared to other sub-groups. CONCLUSIONS: There is a need to tailor specific interventions to alleviate college students' suicide-related behaviors in the US and China, with a particular focus on US females

Meaning in life as a protective factor against suicidal tendencies in Chinese University students.

BACKGROUND: A substantial increase in rates of suicide worldwide, especially among late adolescents and young adults, has been observed. It is important to identify specific risk and protective factors for suicide-related behaviors among late adolescents and young adults. Identifying specific factors across the masses, not only in the Western, but also in the Asian context, helps researchers develop empirically informed intervention methods for the management of protective and risk factors of suicide. METHODS: In the current study, 2074 students (706 males), filled out the Meaning in Life Questionnaire, with subscales of Search for Meaning (MLQ-S) and Presence of Meaning (MLQ-P); the Future Disposition Inventory-24 (FDI-24), with subscales of Positive Focus (PF), Suicide Orientation (SO), and Negative Focus (NF); and the Beck Hopelessness Scale (BHS). These scales measure protective and risk factors that are linked to suicidal behaviors; while suicidal behaviors were measured by the Suicidal Behaviors Questionnaire-Revised (SBQ-R). Mediation analyses were performed to test the models with both the MLQ-S and MLQ-P as the mediators between a) hopelessness, as measured by BHS and suicidal behaviors; and b) PF, SO, and NF, as measured by FDI-24, and suicidal behaviors. RESULTS: We found that only MLQ-P mediated the relation between hopelessness and suicidal behaviors; while both MLQ-P and MLQ-S mediated PF, SO, and NF (as measured by FDI-24), and suicidal behaviors, respectively. CONCLUSION: Meaning in life, including both the presence of meaning in life and search for meaning, can be good protective factors against suicidal behaviors.

The Trauma and Suicide Potential Index-5: Psychometric Evaluation in College Samples.

We provide a brief description of the development of the Trauma and Suicide Potential Index-5 (TSPI-5) and report on the psychometric properties of scores from the new instrument. The TSPI-5 is designed to assess an individual's desire to attempt suicide due to experiencing a trauma. We examined the structure of the instrument in two independent undergraduate samples. Study 1 (N = 415) examined the structure of the TSPI-5 using exploratory structural equation modeling. Study 2 (N = 538) reexamined the instrument structure using the same modeling strategy and also examined other validity estimates. Study 1 demonstrated an adequate fit to the sample data (χ2 [1, N = 415] = 215.99, p < .001, comparative fit index (CFI ) = .969, Tucker-Lewis non-normed fit index (TLI) = .939, root mean squared error of approximation (RMSEA) = .319 [90% confidence interval (CI) = .283, .356], p < .001) and suggested evidence for unidimensionality. Study 2 confirmed the unidimensionality of the TSPI-5 as shown by acceptable fit estimates to the sample data, χ2 (5, N = 538) = 80.45, p < .001, CFI = .996, TLI = .99, RMSEA = .17 (90% CI = .140, .200), p < .001. Scale reliability estimates for the TSPI-5 were good in Study 1 (omega = .94) and Study 2 (omega = .96). The TSPI-5 is a brief unidimensional instrument and its scores demonstrated good reliability and validity for assessing suicide-related behaviors due to experiencing a trauma in undergraduate samples.

Dimensionality, Reliability, Invariance, and Validity of the Multidimensional Social Anxiety Response Inventory-21 (MSARI-21).

Research shows that social anxiety disorder (SAD) is prevalent in the United States, and could interfere with many aspects of a person's life. Although numerous psychological instruments have been developed to measure presence and intensity levels of social anxiety, these instruments fail to capture the range of responses individuals use to mitigate the negative affect associated with the anxiety, namely alcohol use and anger distress. Recently, the Multidimensional Social Anxiety Response Inventory-21 (MSARI-21) was developed to address this limitation and increase our understanding of the complexity of social anxiety. We expand on this work by evaluating the psychometric properties of the instrument, using a combination of exploratory structural equation and bifactor modeling, and item response techniques. Across 2 studies, data indicated the presence of a strong, 3-factor structure (i.e., anger distress, alcohol reliance, and social avoidance), strong internal consistency, and evidence of both convergent and discriminant validity. In addition, results showed that the MSARI-21 multidimensional structure was invariant across gender. We conclude that the MSARI-21 is a valid and valuable tool for assessing individuals' responses to social anxiety, and that future research should evaluate the instrument within other samples to ensure its utility across clinical and subclinical populations.

An Examination of the Psychometric Properties of the Reasons for Living Inventory within a Male Veteran Clinical Sample.

Elevated suicide risk among veteran populations remains a significant public health concern. However, few suicide assessment measures have been validated for veterans. The current study evaluated the reliability and validity of the Reasons for Living Inventory (RFL) scores among veteran populations. The participants included male veterans (N = 421) from a broad range of ages, combat exposures, and history of suicide attempts. Participants completed the RFL and a set of additional self-report measures of relevant constructs in a cross-sectional design. Estimates of internal consistency reliability were adequate for scores on all the original RFL subscale scores. Exploratory factor analysis (EFA) and exploratory bifactor (bi-factor EFA) analyses provided detailed information regarding the 6-factor solution from the original validation studies with the RFL. Additional analyses identified potential correlates for the RFL total and subscale scores. Secondary analyses showed support for evidence of known-groups validity for the RFL total scale score. Overall, this study provides initial support for the RFL as a reliable and valid measure of protective factors in veterans. Future studies may wish to consider further validation of the current findings.

Further psychometric analysis of the 20-item Partner Interaction Questionnaire in an adult sample of smokers.

The 20-item Partner Interaction Questionnaire (PIQ-20) is frequently used to assess social support for adults wanting to stop smoking. Given that social support may play a significant role in quitting success, there is a need to understand the structure and psychometric properties of assessment instruments designed to measure the construct of partner support. The current study examined the psychometric properties of the PIQ-20 when used to assess the frequency of partner behaviors. The study participants included 380 adult volunteers (M age = 41 years, SD = 12; 58% male). To assess internal consistency, we used both the traditional coefficient-alpha and the latent variable modeling composite reliability (coefficient-ρ) procedures. We conducted independent factor analytic methods to address issues of dimensionality and scoring of responses to the PIQ-20 items. Also, we used an item response theory modeling procedure to examine the specificity of scores on the items. Reliability estimates for the PIQ-20 subscale scores were adequate (values ≥.70). The bifactor analysis supported deriving a total score for each subscale. Item response theory modeling demonstrated that the discrimination (a-slope) parameter for each subscale item was significantly different from zero. The majority of items were associated strongly with their respective subscales. Twelve items were identified that could be adopted as a potential short form of the PIQ-20. The PIQ-20 or short form provides an opportunity for assessing positive and negative partner support simultaneously. There is empirical support for the dimensional structures and scoring of responses for both versions of the instrument. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The future disposition Inventory-24: reliability and validity estimates in a large sample of Chinese University students.

BACKGROUND: This study was designed to assess the factor structure, internal consistency reliability, and preliminary psychometric properties of the Chinese version of the Future Disposition Inventory-24 (FDI-24) in a large sample of Chinese university students. METHODS: We translated the English version of the Future Disposition Inventory-24 (FDI-24) into Chinese and examined its factor structure, estimates of internal consistency reliability, and psychometric properties in a representative sample of university students. In particular, students (N = 2,074) from two universities in Shandong Province in China were identified using the multi-stage stratified sampling method. In addition to the FDI-24, we collected preliminary data using self-report instruments that included the Beck Hopelessness Scale (BHS) and a general sociodemographic information questionnaire. RESULTS: The results of the internal consistency reliability estimates were adequate regarding the scores on the three FDI-24 subscales: Cronbach's alpha = .89-.97, Omega total = .85-.96, Revelle's Omega total = .88-.96, the greatest lower bound (GLB) = .89-.96 and Coefficient H = .86-.94. Bivariate correlation analyses showed evidence for criterion and discriminant validity. The 3-factor oblique-Geomin-rotation solution accounted for 62.92% of the total variance in the exploratory factor analysis (EFA). The exploratory structural equation modeling (ESEM) result showed that the 3-factor model provided adequate fit statistics for the sample data: the robust comparative fit index (R-CFI) was .959, robust Tucker Lewis index (R-TLI) was .946 and robust root mean square error of approximation (R-RMSEA) was .090. CONCLUSION: The FDI-24 has a satisfactory factor structure, reliability estimates, and satisfactory evidence of concurrent validity estimates for students with different demographic and cultural backgrounds. The FDI-24 holds promise for use in future investigations with Chinese students.

The Anxiety Depression Distress Inventory-27 (ADDI-27): New Evidence of Factor Structure, Item-Level Measurement Invariance, and Validity.

Three studies examining the factor structure and psychometric properties of the Anxiety Depression Distress Inventory-27 (ADDI-27) extended the initial instrument development studies for this recently introduced inventory. The ADDI-27 is an empirically derived short form of the Mood and Anxiety Questionaire-90 (MASQ-90) comprising three scales: Positive Affect, Somatic Anxiety, and General Distress. The main objectives of Study 1 (N = 700) were to examine the factor structure of the ADDI-27 and its measurement invariance across gender at the item level. The objective of Study 2 (N = 538) was to examine evidence for the convergent and discriminant validity of scores on the ADDI-27. The objective of Study 3 (N = 240) was to assess further evidence for the nomological network and convergent and discriminant validity of the ADDI-27 scores. Results of exploratory structural equation modeling yielded strong support for a 3-factor model, with approximate fit indexes meeting or exceeding the conventional cutoffs. With p ≤ .001 as the criterion for detecting noninvariance, results of measurement invariance analysis suggested that all of the ADDI-27 items were invariant across gender. Results of multivariate validity analyses across 2 studies provided support for the convergent and discriminant validity of scores on the ADDI-27 scales.
