Sažetak
Background: It is widely held that with quality of life (QOL) questionnaires we could evaluate different aspects of well-being and functioning of people with mental health problems. However, research with adults indicates that there might be overlapping between questionnaires measuring aspects of mental health and QOL due to similarities in items representing factors underlying the two constructs. Data about how similar or different are factors underlying items of QOL measures and measures of general psychopathology among adolescents are lacking. Aims of the Study: To explore the underlying factorial structure of a QOL measure and a measure of general psychopathology considered together among adolescents. Methods: 2367 adolescents (1184 males, age mean 15.64 (1.28) years) from Serbia, India, Indonesia, Nigeria, Bulgaria, Croatia, and Turkey participated in an international project. They completed the Pediatric Quality of Life Inventory (PedsQL) as a QOL measure and the Strengths and Difficulties Questionnaire (SDQ) as a measure of general mental health problems. The PedsQL has 23 items in four scales: physical, emotional, social, and school functioning. The SDQ has 25 items in five scales: emotional, conduct, hyperactivity/inattention, and peer problems and prosocial behavior. An exploratory factor analytic approach was considered (principal axis factoring - PAF). Results: All PedsQL and SDQ items were subjected together to a PAF. Ten factors with a eugenvalue of ≥ 1 were extracted explaining 49.3% of the total variance. A majority of the items from both questionnaires loaded on one to three factors corresponding originally proposed scales of the questionnaires. Three PedsQL items (13% of all) and three SDQ items (12% of all) were cross-loading on factors containing items of the opposite questionnaire. Three PedsQL items from the emotional functioning scale (“afraid or scared”, “sad or blue” and “worrying about future”) cross-loaded on a factor containing SDQ items from the emotional problems scale, while three SDQ items (“obeys”, “afraid”, and “distracted”) cross-loaded on factors containing PedsQL items from the emotional or school functioning scale. Discussion: The results indicate that the factors underlying the PedsQL and SDQ measuring constructs are much more different than similar. There are about 13% of similar items in the questionnaires mostly representative of an underlying factor measuring emotional functioning. Implications for Further Research: Authors of any study with adolescents considering a QOL measure and a measure of psychopathology together have to correct the questionnaires’ scores for similar items to avoid treating study validity.
