The Purpose-in-Life Scale (PILS) : internal consistency reliability, concurrent validity and construct validity among Catholic priests in Italy

Abstract

The Purpose in Life Scale was designed to provide a 12-item unidimensional measure of purpose in life employing a five-point Likert rating for each item. The present study supports the psychometric properties of the Italian translation of this instrument among 155 Catholic priests (mean age = 46 years, SD = 12.16). Internal consistency reliability generated an alpha coefficient of .90. The first factor generated by principal component analysis accounted for 49.5% of variance. Concurrent validity against the Purpose in Life Test was supported by a correlation of .63. Construct validity was supported by a correlation of .54 with the Satisfaction in Ministry Scale and by a correlation of -.51 with the Scale of Emotional Exhaustion in Ministry. These properties commend the scale for future use among Catholic priests
