The original LKQ is composed of 16 questions across three dimensions: general knowledge about low back pain (Questions 1, 6, 7, 8, 15), concepts (Questions 2, 3, 4, 5), and treatment (Questions 9, 10, 11, 12, 13, 14, 16). The total score is 24 points, with 8 single-choice questions and 8 multiple-choice questions. Each question has five options, and one point is awarded for each correct answer. A higher total score indicates a greater level of knowledge about low back pain.

The Back Beliefs Questionnaire consists of 14 items to be completed by patients. Nine of these items (Questions 1, 2, 3, 6, 8, 10, 12, 13, 14) are used to assess feelings of helplessness, while the remaining five items (Questions 4, 5, 7, 9, 11) serve as distractors. All items are rated using a 5-point Likert scale, with responses ranging from "1-Strongly Disagree" to "5-Strongly Agree." Scoring is performed by reversing the numerical values selected by the participants and calculating the score based on the helplessness-related items.

This scale quantitatively assesses pain intensity and is highly sensitive, allowing for easy comparison with other pain scales. Patients are asked to rate their pain severity by selecting a number between 0 and 10.

The Roland-Morris Disability Questionnaire consists of 24 statements that assess an individual's perception of their low back pain and related disabilities. These statements cover areas such as physical functioning/effectiveness (15 items), sleep/rest (3 items), psychosocial issues (2 items), household management (2 items), eating (1 item), and pain frequency (1 item). Each statement is presented to the participant, who is asked to indicate whether it applies to their condition for that day. Scoring is based on the total number of "Yes" responses in the "Yes/No" boxes. As a result, the score can range from 0 (no disability) to 24 (maximum disability).
