Attitude towards money (ATM) often determines an individual's overall subjective well-being or happiness. Most past studies have investigated individual values, societal influences and financial acumen largely in isolation from one other. This study aims to develop a more comprehensive model of the antecedents of ATM by taking into account affective, cognitive and social dimensions concurrently by integrating concepts of the Theory Planned Behaviour (TPB) and the Social Cognitive Theory (SCT). Furthermore, this study focused on Generation Y youths in Malaysia as SCT, which suggests that individuals belonging to a particular generation/era and country/jurisdiction share certain collective social realities, hence ATM. In terms of methodology, a survey involving 248 respondents was carried out by utilising multiple regression analysis to test established hypotheses. The empirical findings suggest that, among others, financial awareness has a significant influence on all dimensions of ATM. In addition, parental influence significantly encourages savings and instils restraint tendency in spending, whereas peer influence acts as an influential substitute to parental influence and mass media effectively promotes materialistic values. In terms of practical implications, the study contributes to the understanding of Generation Y's ATM so as to inform the formulation of better financial planning practices and education-related policies.
