The thesis provides insight into how sociodemographic, psychosocial, pain-, sleep-, health literacy- and COVID-19-related factors are associated with various HRQOL (health-related quality of life ) dimensions related to their present HRQOL and changes in their HRQOL and emphasizes the importance of considering and facilitating self-efficacy and self-esteem as important resilience factors for adolescents’ HRQOL.

Hilde Elisabeth Timenes Mikkelsen of the Faculty of and Sciences at the University of Agder has submitted her thesis entitled «The Start Young study Health-related quality of life and pain in adolescents and associated factors; a prospective cohort study of adolescents and their parents» and will defend the thesis for the PhD-degree Thursday 15 December 2022.
Having good health-related quality of life (HRQOL) during adolescence is important, and a significant part of the foundation for HRQOL later in life is laid here.
Previous studies show that an increasing number of adolescents report health complaints such as pain. This may lead to reduced HRQOL.
To better understand HRQOL and pain in adolescents, it is important to investigate factors associated with HRQOL.
Increased understanding of factors associated with HRQOL can improve the ability to develop evidence-based health promotion and intervention programs and help to identify adolescents who need support and help
The overall aim of the thesis was to expand our knowledge of HRQOL and pain by investigating sociodemographic, psychosocial, pain-, sleep-, health literacy and COVID-19-related factors associated with HRQOL in a school-based sample of Norwegian adolescents and their parents during two years of youth.
The thesis is based on a prospective cohort study among adolescents and their parents, from when the adolescents were 14 to 16 years of age.
At the first data collection, 696 adolescents and 561 parents participated.
In the second data collection (two years later), 215 adolescents and 320 parents participated.
Four papers are related to the thesis, of which Papers I-III are based on cross-sectional data and Paper IV is based on longitudinal data.
Paper I showed that 14–15-year-old adolescents reported high HRQOL.
Girls scored worse on HRQOL, self-efficacy, self-esteem, pain, sleep, loneliness and stress compared to boys.
Self-efficacy, self-esteem, loneliness, and stress were most strongly associated with HRQOL in adolescents.
Paper II showed that 14–15-year-old adolescents with pain reported more stress, loneliness and lack of sleep and lower self-esteem, self-efficacy and HRQOL compared to adolescents without pain.
More girls than boys reported pain.
In adolescents with persistent pain, we found that the associations between pain intensity and HRQOL were mediated by self-esteem, but not by self-efficacy.
Paper III showed that the HRQOL of 16–17-year-old adolescents was reduced one year into the COVID-19 pandemic compared to findings from previous studies.
Parents' HRQOL was comparable to Norwegian norms prior to the pandemic.
Further results showed that gender, health literacy, and COVID-19-related worries were associated with adolescents' and parents' HRQOL.
Paper IV showed a reduction in adolescents' HRQOL from the age of 14 to 16
Further results showed that stress, loneliness, and pain contributed to lower HRQOL scores at age 16 compared to age 14, while self-efficacy and self-esteem contributed to higher HRQOL scores.
The thesis provides insight into how sociodemographic, psychosocial, pain-, sleep-, health literacy- and COVID-19-related factors are associated with various HRQOL dimensions related to their present HRQOL and changes in their HRQOL and emphasizes the importance of considering and facilitating self-efficacy and self-esteem as important resilience factors for adolescents’ HRQOL.
Furthermore, the thesis provides insight into pain problems among adolescents. An individual, holistic approach to adolescent pain and increased focus of resilience factors associated with adolescent pain is recommended.
