The World Health Organization Quality-of-Life Scale (WHOQOL-BREF) is a 28-item self-report questionnaire with a five point rating scale for each item (from 1 to 5). There are four domains in WHOQOL-BREF, including physical health, psychological health, social relationships, and environment. The Physical Health domain consists of 7 items, with a total score range of 7 to 35; the Psychological domain includes 6 items, ranging from 6 to 30; the Social Relationships domain comprises 4 items, with scores ranging from 4 to 20; and the Environment domain contains 9 items, with a range of 9 to 45.

Two additional items are assessed separately: Question 1 evaluates an individual's overall perception of quality of life, while Question 2 assesses their overall perception of health. Each of these two items is scored on a scale from 1 to 5.

Domain scores are scaled in a positive direction, meaning that higher scores indicate better quality of life in the corresponding domain.

The Beck Anxiety Inventory (BAI) is a 21-item self-report measure designed to reflect the severity of somatic and cognitive symptoms of anxiety over the previous week. Items are scored from 0 to 3; higher scores indicate greater symptom severity. The BAI scores are classified as minimal anxiety (0 to 7), mild anxiety (8 to 15), moderate anxiety (16 to 25), and severe anxiety (30 to 63).

The Occupational Self-Assessment (OSA) evaluates self-perceived occupational competence and environmental support. The questionnaire includes two sections: Self-Competence and Environment. The Self-Competence section has 21 items divided into three subscales-Skills/Performance (11 items), Habituation (5 items), and Volition (5 items)-and the Environment section has 8 items assessing perceived environmental support. Each item is rated on a 4-point scale, where 1 indicates the lowest and 4 the highest level of perceived competence or support. The possible score ranges are 11-44 for Skills/Performance, 5-20 for Habituation, 5-20 for Volition, and 8-32 for Environment. Higher scores represent greater self-perceived occupational competence and stronger environmental support.

The Canadian Occupational Performance Measure (COPM) is an individualized measure designed for use by occupational therapists to detect self-perceived change in occupational performance problems over time. The therapist calculates an average COPM performance score and satisfaction score. These typically range between 1 and 10, where 1 indicates poor performance and low satisfaction, respectively, while 10 indicates very good performance and high satisfaction.

The Beck Depression Inventory II (BDI-II) is a 21-item self-report questionnaire designed to measure the level of severity of disorders of depression. Items are scored from 0 to 3; higher scores indicate greater symptom severity. In the BDI-II values below 13 points are regarded as no or minimal depressive symptoms. Values between 14 and 19 points indicate a mild expression of depressive symptoms, values between 20 and 28 points a moderate severity. Scores between 29 and 63 are regarded as evidence of severe depressive disorder.

Two additional items are assessed separately: Question 1 evaluates an individual's overall perception of quality of life, while Question 2 assesses their overall perception of health. Each of these two items is scored on a scale from 1 to 5.

Domain scores are scaled in a positive direction, meaning that higher scores indicate better quality of life in the corresponding domain.
