Final Model of Multiple Regression Analysis of Independent Variables with Suicidal Ideation

Variable	Beta	t-value	Significance	Zero-order Correlation
Sex	−.09	−1.77	.078	−.11
Age	.03	0.57	.567	−.08
Pain severity	.01	0.11	.912	.08
Pain duration	.13	2.62	.009	.16
Functional limitations	−.09	−1.53	.127	.11
PHQ	.31	4.82	<.001	.45
PCS	.05	0.84	.404	.34
SPBS	.25	4.38	<.001	.41
IR	.12	2.09	.037	.35

Note. PHQ = Patient Health Questionnaire; PCS = Pain Catastrophizing Scale; SPBS = Self-Perceived Burden Scale; IR = Interpersonal Relations subscale of the Outcome Questionnaire-45. The final model is statistically significant, F(9,290) = 15.24, p < .001, R² = 0.32.
