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.

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.

Towards Higher Psychometric Properties: Testing the Psychological Strain Scales with Larger Samples.

This study aimed to further test the psychometric properties of the Psychological Strain Scales (PSS) with larger samples. A cluster sampling method was employed to recruit 13,250 college students from seven provinces in China. Descriptive statistics, item statistics, Cronbach's alpha, factor analysis, and correlation analysis were evaluated. Cronbach's alpha coefficient was 0.958 and Guttman's split-half coefficient was 0.866. All the item-total correlations were larger than 0.45 except one. Results from Exploratory Factor Analysis and Confirmatory Factor Analysis supported the four dimensions of psychological strains (value strain, aspiration strain, deprivation strain, and coping strain). The PSS was strongly correlated to the Depression, Anxiety, and Stress Scale (DASS-21), which was commonly used to measure risk for suicide and was predictive ofsuicidality as measured by the SBQ-R. The PSS was a self-report instrument with high reliability and validity which could be applied for extensive use in research to measure psychological strains.HighlightsThis is the first study testing the psychometric properties of the PSS in an unusually large sample.Confirmatory factor analysis was applied to provide empirical evidence to the four-factor structure of the PSS.Psychological strains were found to be significantly correlated with depression, anxiety, and stress symptoms and predictive of suicidality.

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.

Depression, Anxiety, and Stress as a Function of Psychological Strains: Towards an Etiological Theory of Mood Disorders and Psychopathologies.

BACKGROUND: The etiological factors of mood disorders and psychopathologies are understudied. In this paper, we explored whether social psychological strains are related to depression, anxiety, and stress in non-clinical populations. METHODS: 6,305 college students (39.3% men; 60.7% women) from six Chinese provincial-level jurisdictions completed a paper-and-pencil survey with Psychological Strain Scales (PSS-40) and Depression, Anxiety, and Stress Scales-21 (DASS-21), both validated in Chinese populations. RESULTS: Both PSS-40 and DASS-21 have high internal consistency reliabilities, and are highly correlated with each other. Hence, Chinese college students with greater psychological strains (value, aspiration, deprivation, or coping) have greater depression, anxiety, and stress. These results still held after controlling for relevant socio-demographic variables in the multiple regression models. LIMITATIONS: This was a cross-sectional study, and the sample only included several provinces in mainland China, not a representative sample of all of them. CONCLUSIONS: Mood disorders and psychopathologies are linked to suicidal thoughts and behaviors. The results of this study extend the Strain Theory of Suicide from explaining the risk factors of suicidality to mood disorders and psychopathologies. Hence, these findings can inform prevention measures among college students, and possibly the general population.

A comparison between American and Chinese college students on suicide-related behavior parameters.

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.

ANTECEDENTES/OBJETIVO: Estados Unidos y China son las dos economías mundiales más grandes, pero faltan estudios recientes y comparables sobre comportamientos relacionados con el suicidio entre ambos países. Mediante el Suicidal Behavior Questionnaire-Revised (SBQ-R) se realizó una comparación a nivel de ítems para evaluar los comportamientos autoinformados relacionados con el suicidio entre estudiantes universitarios de Estados Unidos y China. MÉTODO: Este estudio involucró a 3.185 estudiantes universitarios con edades comprendidas entre 18 y 24 años (1.185 estadounidenses y 2.000 chinos que fueron seleccionados al azar de una gran muestra de 11.806). Los participantes completaron el SBQ-R de cuatro ítems. RESULTADOS: Las respuestas de los participantes se compararon por país y sexo. Hubo un mayor riesgo general de conductas relacionadas con el suicidio entre estudiantes estadounidenses (24,3%) en comparación con los chinos (17,0%). Los estadounidenses también informaron mayor intento vital, ideación el año anterior y amenaza vital. Las estudiantes universitarias estadounidenses informaron las tasas más altas relacionadas con el suicidio en comparación con otros subgrupos. CONCLUSIONES: Existe la necesidad de adaptar intervenciones específicas para aliviar los comportamientos relacionados con el suicidio en estudiantes universitarios en ambos países, con una atención particular en las mujeres estadounidenses.

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.
