Abstract

The aims of the present study were (a) to develop a Farsi version of the Positive Self Scale (PSS), (b) to investigate the psychometric properties and explore the factorial structure of the PSS, (c) to explore the associations of PSS scores with positive psychology variables, and (d) to examine gender-related differences. The PSS and three self-rating scales of happiness, satisfaction with life, and mental health were administered to a sample of 487 Iranian people with opioid use disorder (PWOUD). Cronbach’s α was .88 for the PSS. Two factors were extracted: the major factor, labelled *Positive Conduct*, and the minor factor, labelled *Success and Confidence*. PSS scores correlated significantly and positively with happiness, satisfaction with life, and mental health scores. The sex-related difference in PSS scores was not significant. The correlations with other well-being scales indicated little differentiation among the various aspects of subjective well-being, suggesting that these constructs are difficult to distinguish from one another. Overall, the PSS demonstrated good psychometric properties in the present Iranian sample, providing evidence for the usefulness of the Farsi PSS in assessing the positive self within the domain of positive psychology.
