Introduction:

The sense of life gives meaning and helps to find an internal support to existence. However, the suffering of an oncological disease could lead to its loss or affectation. Several logotherapists have tried to assess the perception of the sense of life experienced by the human being through standardized assessment instruments. In Cuba, there is no instrument that evaluates this important psychological category.

Objective:

To determine the reliability and validity of the Purpose in Life Test (PIL) in adults with cancer treated in the National Institute of Oncology and Radiobiology of Havana, Cuba.

Material and Methods:

The research consisted of the development of a technology aimed at validating the Purpose in Life Test (PIL) through the analysis of Internal Consistency Reliability and the analysis of the Content and Construct Validity. The Purpose in Life Test (PIL), which was designed by Crumbaugh and Maholick and validated in the Spanish population by the Nobility was submitted to a linguistic and cultural adaptation process. In the design, a group of five experts in Psychology participated in the review of the linguistic component from a context perspective in which the instrument would be applied.

Results:

Overall Cronbach's α was 0,853; items 6,10,12 and 16 of the 20 items that make up the test were modified and, despite the one-dimensional conception of the instrument, 5 correlated components were identified.

Conclusions:

The results confirmed the validity and reliability of the Purpose in Life Test in the patients with cancer studied.
