A 24-item scale was developed to measure Beliefs about the Consequences of Maternal Employment for Children (BACMEC), including beliefs about both benefits (13 items) and costs (11 items). Studies of five samples (n= 375) demonstrate that the total BACMEC scale and its subscales are highly reliable and have good convergent, divergent, and con-current validity. Scores on the Costs Subscale predicted greater sex-role traditionalism, women's employment status (not employed), and an older age of child at which mother's employment was deemed acceptable. Benefits scores predicted women's employment status (employed) and work hours (longer), younger age of child when maternal work is accept-able, and greater support for policies to aid working parents. The scales were not susceptible to a social desirability bias. Suggestions are provided for the use of the BACMEC scale in future research concerning employment and families.
