A method of measuring health-related quality of life (HRQOL) in children between ages 2-18 years that are either healthy or have health conditions. They are flexible in use and are multidimensional, covering physical, emotional, social, and school functioning. The measure consists of four core scales (physical, emotional, social, and school), two broad domain scores (physical and psychosocial functioning), and a total score. The PedsQL uses a 5-point Likert scale for responses (Never a problem, Almost never a problem, Sometimes a problem, Often a problem, and Almost always a problem). Scales are standardized, and scores range from 0 to 100, with higher scores representing better quality of life.

A self-report measure designed to assess an individual's confidence in their ability to control eating behavior in various situations, such as during negative emotions, social pressures, or availability of food. Subjects were asked to rate their confidence on being able to resist the urge to eat using a Likert scale ranging from 0 (not confident) to 9 (very confident); the total score for the WEL is the sum of all 20 items, giving a range of 0 to 180. Higher total scores (closer to the maximum of 180) and higher subscale scores reflect a greater sense of confidence in one's ability to resist eating in challenging situations. Lower total scores (closer to the minimum of 0) and lower subscale scores indicate less confidence in resisting eating in challenging situations.

A self-report tool used to measure an individual's enjoyment of physical activity. It assesses the positive feelings and overall satisfaction associated with engaging in exercise. Respondents are asked to rate "how you feel at the moment about the physical activity you have been doing" using a 7-point bipolar rating scale (1-7) on 18 items. Eleven items are reverse scored where the score values are flipped (i.e., 1=7, 2=6, …). Higher total PACES scores demonstrate greater levels of enjoyment. The lowest possible score is 18 while the highest is 126.

A tool used to evaluate children's perceptions of their body size and shape. It helps identify body image concerns by comparing their self-perceived body figure with a body figure that represents their ideal figure. The scale ranges from 1 to 9, each number representing a body size. A body dysphoria score is derived from the difference between the current body state and ideal body state (CBS - IBS) the participant chooses. Positive scores (where the current size is larger than the ideal) may indicate a desire to be thinner, while negative scores (where the current size is smaller than the ideal) may indicate a desire to be larger. Scores range from -5 to +5. Negative scores indicate a preference for a larger body size than the perceived size. Positive scores indicate a preference for a smaller body size than the perceived size. Scale numbers were combined based on the average total score.

The Impact of Weight on Quality of Life-Kids (IWQOL-Kids) is a validated self-report measure designed to assess weight-related quality of life in adolescents aged 11-19. It includes four subscales-physical comfort, body esteem, social life, and family relations-along with a total score, all of which show strong psychometric properties. Response options range from always true (1) to never true (5). Total scores range from 0-135, where higher scores represent better health-related quality of life.
