The present study evaluated the subjective happiness of Lebanese college youth using a multi-item rather than a single-item subjective happiness measure. An Arabic translation of the Subjective Happiness Scale (SHS) was administered to 273 Lebanese college youth from state- and private-run higher institutions of learning, as was the Arabic Adult Parental Acceptance-Rejection Questionnaire (Arabic PARQ). The reliability and validity of the Arabic SHS was tested in terms of factor analysis, internal consistency, and correlation with Arabic PARQ scores, as was the factorial invariance and relation of the scale across age, sex, marital status, birth order, and college campus. The Arabic SHS showed a reliable unitary structure similar to those found in other cultures, and factorial invariance across sex, marital status, birth order and college campus. While age, sex, marital status and birth order were independent of happiness scores, college students attending the private university reported greater happiness than those from the state-run academic setting. It was concluded that the Lebanese Arabic SHS is a reliable and valid measure of global subjective happiness, its factor structure is similar across other translated versions of the scale, and its scores are independent of age, sex, marital status and birth order.
