Presenting a Pattern of Suicidal Behavior Based on Anxiety with the Mediation of Interpersonal Needs in Suicide Attempters

Anxiety causes suicidal behavior by affecting the level of interpersonal needs. The aim of the present study was to provide a causal model of suicidal behavior based on anxiety with the mediation of interpersonal needs in suicide attempters.

The current research is descriptive-correlational. The statistical population of this research was all the patients who tried to commit suicide in Tehran in 2022, and 396 of them were selected from Baharloo Hospital of Tehran by available sampling. Demographic questionnaire, the "Suicide Behaviors Questionnaire", "Beck Anxiety Inventory" and "Interpersonal Needs Questionnaire" were used to collect data. In the present study, the validity of the instruments was not checked and the reliability was measured by the internal consistency method by calculating Cronbach's alpha coefficient. The data was analyzed with SPSS 26 and Amos version 26 software.

The results of the present study showed that there is a positive and significant direct correlation between anxiety and suicidal behavior (β=0.32, P=0.001), perceived burdensomeness with suicidal behavior (β=0.28, P=0.001), and thwarted belongingness with suicidal behavior (β=0.29, P=0.001). Perceived burdensomeness (Z=6.77, P=0.001) and thwarted belongingness (Z=6.78, P=0.001) mediated the correlation between anxiety and suicidal behavior.

Anxiety has a direct and indirect positive correlation with the mediation of interpersonal needs with suicidal behavior. Therefore, it is suggested to diagnose and examine interpersonal needs in people suffering from anxiety in order to reduce their suicidal behavior.
