Assessing the dimensions and structure of thwarted interpersonal needs

Area of Science:

• Psychology
• Clinical Psychology
• Social Psychology

Background:

• The Interpersonal Theory of Suicide (IPTS) posits that thwarted interpersonal needs, specifically thwarted belongingness (TB) and perceived burdensomeness (PB), contribute to suicidal ideation.
• The Interpersonal Needs Questionnaire-15 (INQ-15) is a key instrument for assessing these needs.
• Understanding the structure and interplay of these needs is critical for suicide prevention and intervention.

Purpose of the Study:

• To evaluate the network structure of thwarted interpersonal needs as measured by the INQ-15.
• To determine the dimensional composition of interpersonal needs within the framework of the IPTS.
• To identify key features and relationships among constructs related to suicidal desire.

Main Methods:

• Utilized network and algorithmic methods for analysis.
• Employed a combined sample of 863 participants from two independent studies.
• Applied network analysis and centrality indices to examine construct composition and relationships.

Main Results:

• Network analysis revealed three stable dimensions: perceived burdensomeness (PB) and two dimensions of thwarted belongingness (TB).
• Findings suggest a network structure rather than a purely latent one for these constructs.
• Loneliness emerged as a potential mechanism linking PB and TB, with identified strong and bridge features.

Conclusions:

• Thwarted interpersonal needs encompass perceived burdensomeness, loneliness, and absence of reciprocal care.
• Loneliness may mediate the co-occurrence of PB and TB experiences.
• While the INQ-15 shows stable dimensions, potential method effects warrant further investigation, necessitating diverse samples for broader generalizability.
