The CPS is a method for assessing individual preferences in medical decision-making roles, consisting of five options that represent five different roles. (A) I prefer to make the decision about which treatment I will receive, (B) I prefer to make the final decision about my treatment after seriously considering my doctor's opinion, (C) I prefer that my doctor and I share responsibility for deciding which treatment is best for me, (D) I prefer that my doctor makes the final decision about which treatment will be used, but seriously considers my opinion, (E) I prefer to leave all decisions regarding treatment to my doctor. The five responses are classified into three categories representing active(A and B), collaborative (C) and passive (D and E) decision-making preference.

This scale comprises 13 items and is divided into three subscales, which measure physician facilitation (4 items), patient information acquisition (4 items), and patient decision-making involvement (4 items). A 5-point Likert scale is used, where higher scores indicate greater perceived involvement in decision-making.

This scale consists of 16 items, with the first 12 items assessing decision experiences, including uncertainty, understanding of information, unclear values, support during the decision-making process, and satisfaction with decisions. It uses a 5-point Likert scale, with higher scores indicating greater decision conflict.

The evaluation of family functioning involves: (1) Balanced Scales: Cohesion and Flexibility, (2) Unbalanced Scales: Disengaged, Enmeshed, Rigid, and Chaotic, (3) Family Communication, and (4) Family Satisfaction. The instrument consists of eight subscales with a total of 62 items, rated on a five-point Likert scale. The Family Cohesion and Flexibility scales include 42 items (0-42), divided into six sections with scores ranging from 7 to 35 per section. The Family Communication scale, which assesses positive communication and openness, contains 10 items (43-52) with scores ranging from 10 to 50. The Family Satisfaction scale, measuring satisfaction with cohesion, flexibility, and communication, also has 10 items (53-62), scoring from 10 to 50. Higher scores on Cohesion and Flexibility suggest a healthier family system; higher scores on Disengaged, Enmeshed, Rigid, and Chaotic indicate dysfunction; higher scores on Communication and Satisfaction denote more positive perceptions.
