Table 1. Overview of the Heinrichs-Carpenter Quality of Life Scale (QLS) and Work Readiness Questionnaire (WoRQ).

	QLS				WoRQ
Objective	To assess health-related quality of life and functioning in patients with schizophrenia during the preceding four weeks [7]				To assess functional capacity to work and work readiness in patients with schizophrenia [6]
Rater	Clinician				Clinician
Domain	Interpersonal relations	Instrumental role	Intrapsychic foundationsa	Common objects and activities
Purpose	To examine a patient’s social experience	To assess a patient’s work functioning	To assess a patient’s sense of purpose and motivation	To evaluate a patient’s level of participation in the community
Items	1. Householda 2. Friends 3. Acquaintances 4. Social activity 5. Social network 6. Social initiative 7. Withdrawal 8. Sociosexual	9. Occupational role 10. Work functioning 11. Work level 12. Work satisfactiona	13. Sense of purpose 14. Motivation 15. Curiosity 16. Anhedonia 17. Aimless inactivity 20. Empathy 21. Emotional interaction	18. Commonplace objects 19. Commonplace activities	1. The patient generally adheres to a treatment plan, including medication. 2. The patient is able to carry out Activities of Daily Living. 3. The patient is able to consistently keep appointments and schedules with only minimal assistance. 4. The patient would have adequate impulse control when interacting with authority figures, peers or coworkers, and potential customers. 5. The patient’s behavior would not make others uncomfortable in a work situation. 6. The patient’s appearance would not make others uncomfortable in a work situation. 7. The patient’s current symptoms would not interfere with the ability to hold a job. 8. Based on your clinical judgment, is this patient ready for work?
Scoring	Each item is rated on a 7-point scale, ranging from 0 (severe impairment) to 6 (normal or unimpaired functioning), and definitions are provided for 4 anchor points of the 7 points. Higher scores indicate a better quality of life and functioning, and QLS total scores thus ranges from 0–126.				Each statement item is rated on a 4-point scale, ranging from 1 (strongly agree) to 4 (strongly disagree). In the final item 8, the clinician indicates if the patient is ready for work independent of the score in each item (Yes/No). WoRQ total score is the sum of items 1–7, and thus ranges from 7–28 with lower scores indicating better functioning.

^a For domain scores and total scores, scores for patients who could not be rated on items 1 and 12 were prorated on the basis on the items 2–8 and items 9–11, respectively.
