Domains of Change from Baseline to 6-months and Operationalization of “Experiencing Difficulties” vs. “Expected Trajectories”¹

Domain	Instrument	Details	Operationalization of expected trajectories and experiencing difficulties	Missing at Baseline	Missing at 6 Months
Community Integration - Physical	Community Integration Scale (CIS) - Physical subscale	▪7 item subscale of the full 11-item CIS instrument; examines a person’s physical (community presence) integration in the community	Expected trajectory: Movement to a higher count, compared to baseline OR no change from baseline	47 (15.6%)	47 (15.6%)
		▪Responses are summed for a total score, with higher scores indicating greater community integration	Experiencing difficulty: Movement to a lower count, compared to baseline
		▪References: [28-30]
Community Integration - Psychological	Community Integration Scale (CIS) - Psychological subscale	▪4 item subscale of the full 11-item CIS instrument; examines a person’s psychological (sense of belonging) integration in the community	Expected trajectory: Movement to a higher quintile, compared to baseline OR no change from baseline	6 (1.99%)	54 (17.9%)
		▪Responses are summed for a total score, with higher scores indicating greater community integration	Experiencing difficulty: Movement to a lower quintile, compared to baseline
		▪References: [28-30]
Mental Illness Symptomatology	modified Colorado Symptom Index (CSI)	▪14-item scale that measures the frequency of symptoms of psychiatric illness in the past month	Expected trajectory: Movement to a lower quintile, compared to baseline OR no change from baseline	27 (8.97%)	64 (21.3%)
		▪Sum of all 14 items produces the overall CSI score; higher scores indicate greater psychiatric symptomatology; a score greater than 30 indicates the presence of a probable disorder	Experiencing difficulty: Movement to a higher quintile, compared to baseline
		▪References: [31-34]
Substance Use	Global Appraisal of Individual Need – (GAIN-SS) Substance Problem Subscale	▪5-item subscale with individual items scored on a 4-point scale for a given period of time (lifetime or past year or past month or never)	Expected trajectory: Movement to a lower count compared to baseline OR no change from baseline	2 (0.66%)	43 (14.3%)
		▪Number of responses with a particular value is counted (depending on time frame under examination)	Experiencing difficulty: Movement to a higher count, compared to baseline
		▪Higher count values indicating higher substance use symptoms
		▪References: [35,36]
Community Functioning	Multnomah Community Ability Scale (MCAS)	▪17-item instrument that measures the degree of functional ability	Expected trajectory: Movement to a higher quintile, compared to baseline OR no change from baseline	0 (0%)	75 (24.9%)
		▪Total MCAS score is sum of all 17 questions. Categories of ability based on total score:	Experiencing difficulty: Movement to a lower quintile, compared to baseline
		−17 to 47 indicates low level of ability
		−48 to 62 indicates some disability
		- > 63 indicates little disability
		▪References: [37-39]
Quality of Life	Quality of Life Inventory (QoLI20)	▪20-item scale that assesses the life circumstances of people with severe and persistent mental illness	Expected trajectory: Movement to a higher quintile, compared to baseline OR no change from baseline	26 (8.64%)	71 (23.4%)
		▪A total sum of all items produces a score ranging from 20 to 140, with higher scores indicating greater satisfaction with life	Experiencing difficulty: Movement to a lower quintile, compared to baseline
		▪References: [40-42]
