This analysis, carried out for an Italian customer, concerns the psychometric properties of the Reason for Living Inventory (RFL) of Linehan, Goodstein, Nielsen and Chiles (1983) in its Italian version.
This study was performed on a sample of 200 subjects, interviewed with the questionnaire RFL
My contribution to the research consisted in performing appropriate statistical analysis for the research objectives, which were to assess the following aspects:
- Internal consistency of RFL scale applied to the Italian, through measures of reliability (Cronbach's alpha)
- Differences in the "reasons to live" between the experimental and the control group (with the Student t test and non-parametric tests)
- Correlations between subscales RFL and BDI (Pearson Correlation)
- Statistical dependence links between pairs of variables (religious belief and group of alcoholics in treatment of belonging, through contingency tables and Chi square test)
- Effects of socio-demographic variables and religious beliefs on the average of sub-scales and the items RFL (various applications of Analysis of Variance).
