Meaning in life among adolescents: Factorial invariance of the purpose in life test and buffering effect on the relationship between emotional dysregulation and hopelessness

Objective The purpose of the present study was threefold: first, to analyse the psychometric properties of a 10‐item Spanish version of the Purpose in Life Test, which assesses meaning in life (MiL), in a sample of community adolescents; second, to analyse the differences between the age and gender groups; and third, to analyse whether MiL buffers the relationship between emotional dysregulation and hopelessness. Method Participants were 1,599 adolescents from 12 to 19 years old, M  = 15.69, SD  = 2.14. The Purpose in Life Test‐10 Items, the Beck Hopelessness Scale, and the Difficulties in Emotional Regulation Scale were used. Results A nine‐item version showed good fit, psychometric properties (internal consistency, construct, and concurrent validity), and factorial invariance across gender and age (12–15 years/16–19 years). Difference in MiL between boys and girls was not significant, whereas between age groups was significant. MiL had a strong buffering effect on the relationship between emotional dysregulation and hopelessness. Discussion It is desirable to promote the sense of MiL in adolescents. MiL plays a significant and strong mediator role in the relationship between emotional dysregulation and hopelessness, reinforcing the positive role of MiL in mental health and as a resource for facing adversity.
