Introduction

The Interpersonal Needs Questionnaire (INQ-15) and the Acquired Capability for Suicide Scale - Fearlessness About Death (ACSS-FAD) have been introduced to evaluate the theoretical constructs posit by Joiner’s Interpersonal Psychological Theory of Suicide (IPTS).

Objectives

The present study aimed to evaluate the psychometric properties of the INQ-15 (which measures Thwarted Belongingness, TB, and Perceived Burdensomeness, PB) and the ACSS-FAD (measurement of Fearlessness About Death, FAD, dimension of the acquired capability) in a population of Italian university students.

Methods

Since there was no Italian version of the ACSS-FAD, we have translated it through an accurate multistage procedure. ACSS-FAD and INQ-15 have been administered to a sample of 1,665 Italian university students. We analyzed the factorial structure of the INQ-15 and the ACSS-FAD, their reliability, criterion, convergent and discriminant validity.

Results

Principal Component Analysis confirmed a two-dimensional structure for INQ-15 and a one-factor structure for ACSS-FAD. Internal consistency reliability of the scales was good, respectively TB: α = .85; PB: α = .90; and FAD: α = .85. The INQ-15 demonstrated concurrent associations with suicidal ideation, while the ACSS-FAD with a history of suicidal planning/suicide attempt. Convergent and discriminant validity were also in line with previous studies.

Conclusions

Both INQ-15 and ACSS-FAD appropriately capture the respective constructs, proving to be valid measures for the assessment of suicide risk factors among Italian university students according to the IPTS. The valuable psychometric properties of the two scales established with this study in the Italian context encourages their use to advance the clinical understanding and prevention of suicide.
