Table 2. Summary of hierarchical multiple regression analysis: suicide exposure, caring behaviors, and psychological variables as predictors of caregiver burden in a sample of carers.

Predictors	R	Adj R 2	B	95% CI for B		β	sr 2
				LL	UL
Note. R = multiple correlation between the observed and predicted values of the DV, Adj R2 = adjusted amount of variation in the outcome variable that is accounted for by the model, B = unstandardized beta coefficients, CI = confidence intervals, LL = lower limit, UL = upper limit, β = standardized beta coefficients, and sr2 = squared semipartial correlation (amount of unique variance in the dependent variable explained by a predictor after controlling for the other predictors in the model). Results reported in the table correspond to Step 4 in the model. aPersonal characteristics: Gender: 1 = male; 2 = female; Time since last attempt: 1 = less than 1 month; 2 = 1–6 months; 3 = 7–12 months; 4 = 1–2 years; 5 = 3–5 years; 6 = 6–10 years. *p < .05. **p < .01. ***p < .001. N = 428 for this analysis (seven cases reporting their gender as “other” were excluded). Bold values indicate statistical significant effects.
