“…Some scholars suggest that there may be some cultural and linguistic differences in INQ#9 (Hallensleben et al, 2016; Iliceto et al, 2020). Nonetheless, consistent with other studies (Brookings & Pederson, 2019; Mitchell et al, 2017), TB‐8, excluding INQ#9, showed sound internal consistency as well.…”

“…Furthermore, although some recent studies utilized SBQ‐R to assess suicide risk in terms of INQ‐15 (Brookings & Pederson, 2019) and IPTS (Schönfelder et al, 2019), the current results were conditioned by the limitations of SBQ‐R. Importantly, its lack of ability to address suicide attempts impeded the study to address people with lumping ideations, chronic ideations, and (multiple) attempts.…”

The aim of the current study was to validate the Interpersonal Needs Questionnaire (INQ‐15) and to test its reliability in Persian‐speaking Iranian undergraduate students. In this cross‐sectional study, 485 undergraduate students (age: 20.66 ± 1.42, 60% female) were assessed on the two subscales of perceived burdensomeness (PB) and thwarted belongingness (TB) and the Suicide Behavior Questionnaire‐Revised (SBQ‐R). Exploratory structural equation modelling (ESEM) confirmed the construct validity of INQ‐14, excluding INQ#9. In addition, INQ#8, articulated in an equivalent Persian phrasing, loaded well on TB. The measurement model tested by confirmatory factor analysis (CFA) suggested INQ#11 to be eliminated, resulting in INQ‐13‐P to consist of PB and TB‐7. The internal consistency and convergent/discriminant validity were established. The concurrent validity of PB was solidly established in terms of past year suicidal ideation (PY‐SI) above and beyond anxiety, depression, prior suicidality, and TB‐7. The effect of PB on PY‐SI was stronger, where prior suicidality had already occurred or the perceived likelihood of future suicide (PLFS) was high. Moreover, TB‐7 could only indicate PY‐SI, where prior suicidality had already occurred or PLFS was high, albeit when PB was omitted. The interaction term was significant; however, beyond anxiety and depression, the effect of TB‐7 on PY‐SI was significant where PB was very high (n = 40, 8.25%). Therefore, future studies can utilize INQ‐13‐P as a valid and reliable instrument in Persian‐speaking populations. However, further studies should examine the construct validity of TB and its relationship with suicide ideation in different populations.

“…ROC analyses revealed good performance of the INQ-8 Spanish version subscales of perceived burdensomeness and thwarted belongingness. These results are in agreement with previous publications which reported that INQ-15 may be useful in the detection of SI [73]. In fact, our results are in line with those presented by Mitchell et al [74] who reported that perceived burdensomeness had larger effects on SI than thwarted belongingness.…”

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

et al. 2021

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.

“…Moreover, it has been found that cut-off scores of the INQ-15 of 17 for PB and 37 for TB correctly classificated high-risk and low-risk women with chronic illnesses, thus supporting the clinical relevance of the instrument (23). Mitchell et al (24) also found INQ-15 as a useful instrument to predict suicide ideation-related outcomes in psychiatric inpatients.…”

BackgroundThwarted Belongingness (TB) and Perceived Burdensomeness (PB) are considered risk factors of suicide behavior in the Interpersonal Theory of Suicide and constitute the main factors of the Interpersonal Needs Questionnaire—INQ.AimsThe present study analyzes the internal consistency, construct validity, and invariance across sex and age of the INQ-15, which comprises two subscales, in a sample of Spanish community adolescents.MethodsParticipants were 1,536 adolescents from 12 to 19 years old. The INQ-15, the total number of non-suicidal self-injuries (NSSI), the Hopelessness Scale, and the Purpose in Life Test-Adolescents (PIL-A) were used.ResultsThe INQ-15 showed good internal consistency for TB (ω¯ = 0.88) and PB (ω¯ = 0.78) subscales and construct and concurrent/discriminant validity in the whole sample. Both the PB and TB subscales showed a good fit {SBχ2(9) = 6.448, p = 0.694, CFI = 1.000, RMSEA = 0.000 [90% CI (0.000, 0.022)] and SBχ2(27) = 248.973, p = 0.000, CFI = 0.922, RMSEA = 0.073 [90% CI (0.065, 0.082)]}, respectively. Regarding the invariance analyses, we found (1) non-invariance in the PB subscale across sex groups and metric, scalar, and stric invariance across age groups, and (2) that it was not possible to perform the invariance analysis for the TB subscale across both sex and age because the fit was not adequate for both boys and 12–15 years old groups. Positive and significant relationships were found between the INQ-15 subscales and hopelessness and NSSI frequency, and negative and significant correlations with meaning in life.ConclusionsThe INQ-15 is a valid instrument for assessing TB and PB in Spanish adolescents. Future studies should analyze the invariance of this instrument in adolescents across sex and age.
