Identifying Psychological Strains in Suicide Notes.

Area of Science:

• Psychology
• Criminology
• Mental Health Research

Background:

• Strain Theory posits that psychological strains precede suicidal behaviors and mental disorders.
• Empirical validation of Strain Theory in the context of suicide is crucial for understanding etiology.
• Suicide notes offer a direct window into the psychological state of individuals at the time of death.

Purpose of the Study:

• To empirically test Strain Theory using a large dataset of suicide notes.
• To identify the prevalence of specific psychological strains in suicide notes.
• To examine the association between psychological strains and concepts like thwarted belonging and perceived burdensomeness.

Main Methods:

• Content analysis of 261 suicide notes collected from Tasmania, Australia.
• Quantification of four distinct psychological strains within the notes.
• Comparison of psychological strain ratings with established measures of social connection and burden.

Main Results:

• At least one psychological strain was identified in 39.6% of the analyzed suicide notes.
• Aspiration and coping strains were the most frequently observed types of psychological strain.
• Aspiration and coping strains correlated with thwarted belonging; aspiration and deprivation strains correlated with perceived burdensomeness.

Conclusions:

• The findings provide empirical support for Strain Theory's proposition that psychological strains are antecedent to suicidal behavior.
• Specific strains, particularly aspiration and coping, are significantly associated with key interpersonal factors contributing to suicide.
• This research highlights the complex interplay of individual psychological states and social-evaluative processes in suicidal ideation.
