- W73155668 abstract "Group-based trajectory analysis is an innovative statistical method to identify distinct populations over time. We used this approach to characterize patterns of change in distress using shortened scales (depressive symptoms (CESD), anxiety (POMS), and caregiver burden (CRA)) in caregivers (CG) of persons with primary malignant brain tumors. In an ongoing longitudinal study, 98 CGs were interviewed within a month of their care recipients' diagnosis and at 4, 8, and 12- months afterwards. We used SAS Proc Traj to select models based on clinical criteria and statistical judgment. We identified 2 trajectories for depressive symptoms, 2 for anxiety, and 3 for caregiver burden. An estimated 61.2% of CGs had low CESD (range: 0-30) scores at baseline (mean (M)=5.3, standard deviation (SD) = 3.6) and remained low (M=2.7, SD=2.8) at 12-months (p=0.06 for trajectory slope); the remaining CGs (38.8%) had high scores at baseline (M=14.4, SD=5.3) that significantly decreased by 12-months (M=9.1, SD=4.6; p=0.01). An estimated 20.4% of CGs had low POMS (range: 3-18) scores at baseline (M=6.0, SD=2.2) that decreased significantly (M=4.0, SD=1.1) at 12-months (p=0.002); the remaining CGs (79.6%) had high scores at baseline (M=10.2, SD=2.1) that decreased significantly by 12-months (M=7.8, SD=1.5; p=0.001). An estimated 20.4% of CGs had low CRA (range: 5-25) scores at baseline (M=10.5, SD=2.7) that decreased significantly (M=6.4, SD=1.3) at 12-months (p<0.001); the moderate trajectory included 26.5% of CGs with consistent scores at baseline (M=14.2, SD=2.0) and 12 months (M=11.0, SD=1.4; p=0.51); the majority of CGs (53.1%) had consistently high scores at baseline (M=19.7, SD=2.1) and (M=20.0, SD=2.4) at 12 months (p=0.85). Logistic and multinomial regression results revealed that CGs with low emotional stability were more likely to belong to the high depressive symptoms (p=0.007) and anxiety (p=0.002) trajectory groups. CGs were more likely to belong to the moderate to high caregiver burden trajectory group if their care recipients had more aggressive tumor types (p=0.004) or lower constructional ability (p=0.05). The public health significance of this work is that trajectory analysis provides a way to identify CGs at risk of increasing psychological distress so that suitable interventions can be developed and targeted." @default.
