The Teenager’s Quality of Life (T-QoL) questionnaire is designed to measure the current impact of any skin disease on the quality of life of teenagers/adolescents.

T-QoL consists of 18 questions. It is self-explanatory and can be simply handed to the person who is asked to fill it in, without the need for detailed explanation.

Who can use it

Any teenager/adolescent who has a skin condition or disease can complete T-QoL.

T-QoL can be used by clinicians in order to assist the clinical consultation, evaluation and clinical decision-making process, by pharmaceutical companies, with-profit organisations, students or researchers.

Depending on who you are what you're using the questionnaire for, you may need to apply for a licence and pay a fee.

How to score it

The scoring of each question is as follows:

• Never = 0
• Sometimes = 1
• Always = 2

The T-QoL total score is calculated by summing the score of each of the 18 questions, resulting in a maximum of 36 and a minimum of 0.

The questions in the T-QoL are divided into three parts (domains):

• Self-image (8 questions)
• Physical well-being and future aspirations (4 questions)
• Psychological impact and relationships (6 questions)

The T-QoL score can also be reported as three separate scores:

• T-QoL self-image (score range 0-16)
• T-QoL physical/future (score range 0-8)
• T-QoL psychological/relationships (score range 0-12)

Meaning of scores

The higher the score, the greater the impairment of quality of life.
