Relationships between career maturity and self-concept, parenting style and individualism-collectivism across Australian and Thai cultural contexts were investigated. Berry's ("1969") etic-emic model for adapting instruments for cross-cultural research was applied. "Derived etic" status was achieved for the career planning scale, five self-concept sub-scales and the Parental Bonding Instrument. Mean score comparisons revealed few significant differences between Australia and Thailand. None of the independent variables were associated with Thai career planning. Academic and social self-concept scales and father care were related to career planning in Australia. Implications are discussed.
