Validity, Reliability and Factor Structure of The Life Attitude Profile-Revised (LAP-R)

Considering the importance of meaning of life and its role in mental health, the purpose of the current study is to examine the psychometric properties of LAP-R, an instrument that measures the meaning of life on the extensive components.

500 students from different levels of education of Shahed University of Tehran were selected by proportional sampling method and after translating and retranslating of LAP-R, responded to LAP-R with the Spirituality Assessment Inventory (SAI), the Self-Esteem Rating Scale- Short Form (SERS-SF) and the Positive Affect and Negative Affect Scale (PANAS). After performing the questionnaires, the results of validity and reliability of LAP-R were analyzed by statistical analysis.

As the results of current study showed, there was a high correlation between many subscales of LAP-R with SAI, SERF-SF and PANAS. Also, the Cronbach's alpha coefficient and the correlation between the test-retest of LAP-R was appropriate (P<0.01). The correlation of the test-retest of this scale ranged from 0.61 to 0.81(P<0.01). Also, Cronbach’s alpha coefficients of the subscales and the overall score of this scale ranged from 0.65 to 0.86.

Considering the appropriate correlation of LAP-R with other scales as well as the results of test-retest correlation and Cronbach`s alpha, it can be said that this questionnaire has appropriate validity and reliability. Declaration of Interest: None
