Interpersonal Needs Questionnaire (INQ-15)
The INQ-15 (Van Orden et al., 2012) is a 15-item self-report assessment
of thwarted belongingness (9 items; Cronbach’s alpha = .88),) and
perceived burdensomeness (6 items; Cronbach’s alpha = .91). Each item is
rated on a 7-point Likert-type scale ranging from 1 (not at all
true for me ) to 7 (very true for me ). Scores are coded in a way
where higher scores indicate greater severity of thwarted belongingness
and perceived burdensomeness. The INQ-15 has demonstrated strong
psychometric properties (Van Orden et al., 2012).
Depressive Symptom
Index-Suicidality Subscale
(DSI-SS)
The DSI-SS (Joiner et al., 2002) is a four-item self-report assessment
developed to evaluate suicidal ideation severity. This measure assesses
the frequency and intensity of suicidal ideation and impulses in the
past 2 weeks. Scores on items range from 0 to 3; item scores are summed
for a total score, with higher scores indicating a higher severity of
suicidal ideation. The DSI-SS demonstrated good internal consistency and
construct validity in the validation study (Joiner et al., 2002).
