Factor Structure and Validity of the Suicidal Narrative Inventory Among Indian Adults.

Background: The suicidal narrative is a presuicidal state comprising several risk factors for suicide and is assessed using the Suicidal Narrative Inventory (SNI). Aims To assess the internal structure, reliability, and validity of SNI among Indian adults. Methods Between August 2020 and January 2021, the SNI, together with other self-report measures, was administered to adult respondents using an online anonymized questionnaire. Confirmatory factor analysis (CFA) was carried out to test the factor structure of the SNI. Results Usable responses were obtained from 302 participants (Mage = 43.5 ± 17.9 years, 53.6% female). The results of an eight-factor CFA of the SNI resulted in good model fit (χ2 [637] = 969.73, p < .001, comparative fit index = 1.00, root mean square error of approximation = .04). Internal consistencies of SNI subscale scores ranged from acceptable to excellent (range α = .67-.92). Most subscales significantly converged with other measures although these associations were minimal for the goal disengagement and reengagement subscales. Limitations The use of an online survey method to collect data introduced sampling bias. Conclusion The eight-factor CFA of the SNI, among Indian adults, was consistent with prior data. Our findings provide preliminary support for the use of SNI to assess the suicidal narrative construct among Indian adults.

Factor structure and validity of the Revised Suicide Crisis Inventory (SCI-2) among Indian adults.

BACKGROUND: There is a dearth of cross-cultural data on the psychometric properties of the revised Suicide Crisis Inventory (SCI)- 2. Our objective was to examine the factor structure, reliability, and validity of the SCI-2 among Indian adults. METHODS: Using an online survey method, between August 20, 2020 and January 31, 2021, an anonymous questionnaire containing general sociodemographic information and self-report measures was circulated over email and social media. Confirmatory factor analyses (CFA) of the SCI-2 was carried out. We also examined the internal consistency of the SCI-2 and tested its convergent validity against the Suicide Narrative Inventory (SNI) and the Perceived Stress Scale (PSS-10). RESULTS: A total of 302 participants (Mean age = 43.5 ± 17.9 years, 53.6% female) were obtained. Results of the one-factor CFA indicated good model fit (χ2[1769] = 5368.75, p < 0.001, Comparative Fit Index [CFI] =0.99, Root mean square error of approximation [RMSEA] =0.08). Similarly, the five-factor CFA also exhibited strong model fit (χ2[1759] = 4215.54, p < 0.001, CFI = 1.00, RMSEA =0.07). Comparison of these models indicated that the five-factor model demonstrated superior model fit (Δχ2[10] = 278.88, p < 0.001). The SCI-2 total and subscale scores showed excellent internal consistency and good convergent validity against most domains of the SNI and PSS-10. CONCLUSION: Among Indian adults, the SCI-2 demonstrated good psychometric properties with the proposed five-factor solution providing the best fit. These findings provide support for the SCI construct and its assessment with the SCI-2 in an Asian setting.
