The scale consists of 10 items (e.g. "Usually I am able to control a situation" or "In unexpected situations, I always know how I must behave myself"). Responses are rated on a 4- point Likert-scale ranging from "absolutely not true" (weighted as 1) to "absolutely true" (weighted as 4), where the higher GSES total scores indicate stronger self-efficacy beliefs.All responses are added to a sum score. The range is from 10 to 40 points with a higher score indicating more self-efficiency.

The scale includes 12 items, each of which refer to the people to whom the respondent would turn if he/she had problems of a personal, health or family nature, as well as financial and employment problems. Responses are scored on a 7-point scale from 1 ('completely disagree') to 7 ('completely agree'). The MSPSS index and three subscales - family, friends and significant others - are computed. MSPSS total score ranged from 12 to 84, with a higher score indicating greater satisfaction with total support. Subscores ranged from 4 to 28, with higher score indicating greater satisfaction.

A total score of 1 to 15 items was computed while item 16 assessing "overall life satisfaction" was not included to avoid exaggerated scores. The total score was averaged from items 1 to 15 and ranged from 1 to 5, with higher scores indicating higher satisfaction.
