A validation study of the Zanmi Lasante Depression Symptom Inventory (ZLDSI) in a school-based study population of transitional age youth in Haiti

Table 3 Relationship of ZLDSI and other measures of depression and suicidality (n = 120, unless otherwise indicated)

	ZLDSI < 12 (n = 82)	ZLDSI ≥12 (n = 38)	p
CES-D^a, mean (SD), (n = 111)	17.72 (10.21) (n = 73)	32.41 (10.32) (n = 38)	<.001
During the past 12 months, how often have you been so worried about something that you could not sleep at night? (GSHS)^b, mean (SD)	2.10 (.98)	3.24 (.88)	<.001
During the past 12 months, how often have you felt lonely? (GSHS) ^b, mean (SD)	1.90 (.90)	2.89 (1.03)	<.001
During the past 12 months, how often have you had a hard time staying focused on your homework or other things you had to do? (GSHS) ^b, mean (SD), (n = 119)	2.54 (1.11) (n = 81)	3.24 (1.22)	.003
SRIB in GSHS^c, % cases (n)	0.0% (0)	21.15% (8)	<.001
SRIB in ZLDSI, % cases (n)	2.44% (2)	36.84% (14)	<.001

p-values correspond to independent sample t-tests for mean differences and Fisher’s exact tests for proportions
^a Scores from the CES-D are based on a 20-item self-report assessment, slightly modified for this study [18]. Responses are scored 0 to 3, and a total sum score ranges from 0 to 60
^b Response options were: Never = 1, Rarely = 2, Sometimes = 3, Most of the time = 4, and Always = 5
^c Suicide-related ideation or behavior (SRIB) identified on the GSHS was coded as present if there was an affirmative answer to one or more of the following questions as indicated by a “yes” response to the first two and any value > = 1 time in response to the third question:
1. During the past 12 months, did you ever seriously consider attempting suicide?
2. During the past 12 months, did you ever make a plan about how you would attempt suicide?
3. During the past 12 months, how many times did you actually attempt suicide?
