College students who engage in solitary binge drinking (i.e., binge drinking while alone) have been found to be higher in depression and in severity of recent suicidal ideation than students that binge drink only in social contexts (social binge drinkers). This study examines whether those at greater risk for suicide, as indicated by two variables (1) a history of suicide attempts and (2) current severity of recent suicidal ideation, are more likely to be solitary binge drinkers as opposed to social (only) binge drinkers.

Run a standard/simultaneous (binary) logistic regression analysis to examine whether severity of recent suicidal ideation (as measured by the ASIQsqrt in the dataset) and a previous history of a suicide attempt (as measured by Attempt in the dataset) help to predict the likelihood of being a solitary as opposed to a social binge drinker. Include two control variables in your analysis, age and gender. Use the dataset titled: Homework 7 dataset – solitary binge drinking . Please note that the coding for the dichotomous variables can be seen within SPSS under Values in Variable View.

Provide a write-up following the example provided in lecture 7. For the dichotomous variables in the model, be sure to provide the results in simple language (i.e., individuals with a previous suicide attempt were X times more likely to be…).

In addition to the analysis and write-up above, answer the following questions:

1. The betas for a logistic regression analysis are hard to interpret without doing some additional math. Why are these betas hard to interpret?
2. What is this additional math that is being done to the betas to make them more interpretable?
3. What does the OR (Exp[B]) for a continuous variable mean or, put another way, how do you interpret the OR for a continuous variable?
