Improving gambling survey research using dual-frame sampling of landline and mobile phone numbers

Gambling prevalence studies are typically conducted within a single (landline)&nbsp;telephone sampling frame. This practice continues, despite emerging evidence that significant&nbsp;differences exist between landline and mobile (cell) phone only households. This study&nbsp;utilised a dual-frame (landline and mobile) telephone sampling methodology to cast light on&nbsp;the extent of differences across groups of respondents in respect to demographic, health, and&nbsp;gambling characteristics. A total of 2,014 participants from across Australian states and&nbsp;territories ranging in age from 18 to 96 years participated. Interviews were conducted using&nbsp;computer assisted telephone interviewing technology where 1,012 respondents from the&nbsp;landline sampling frame and 1,002 from the mobile phone sampling frame completed a&nbsp;questionnaire about gambling and other health behaviours. Responses across the landline&nbsp;sampling frame, the mobile phone sampling frame, and the subset of the mobile phone&nbsp;sampling frame that possessed a mobile phone only (MPO) were contrasted. The findings&nbsp;revealed that although respondents in the landline sample (62.7 %) did not significantly&nbsp;differ from respondents in the mobile phone sample (59.2 %) in gambling participation in the&nbsp;previous 12 months, they were significantly more likely to have gambled in the previous&nbsp;12 months than the MPO sample (56.4 %). There were no significant differences in internet&nbsp;gambling participation over the previous 12 months in the landline sample (4.7 %), mobile&nbsp;phone sample (4.7 %) and the MPO sample (5.0 %). However, endorsement of lifetime&nbsp;problem gambling on the NODS-CLiP was significantly higher within the mobile sample&nbsp;(10.7 %) and the MPO sample (14.8 %) than the landline sample (6.6 %). Our research&nbsp;supports previous findings that reliance on a traditional landline telephone sampling&nbsp;approach effectively excludes distinct subgroups of the population from being represented inresearch findings. Consequently, we suggest that research best practice necessitates the use&nbsp;of a dual- rame sampling methodology. Despite inherent logistical and cost issues, this&nbsp;approach &nbsp;needs to become the norm in gambling survey research.</span

Mining the gold: assessing students by ability, not disability

It\u27s time to shift from a deficit model that focuses on the disability of students with additional needs to a model that focuses on their abilities
