The increase in mobile telephone only households may be a source of bias for traditional landline gambling prevalence surveys. Aims were to: 1) identify Australian gambling participation and problem gambling prevalence using a dual-frame (50% landline and 50% mobile telephone) computer assisted telephone interviewing methodology; 2) explore the predictors of sample frame and telephone status; and 3) explore the degree to which sample frame and telephone status moderate the relationships between respondent characteristics and problem gambling.
