Experimental Design: Teen Attitudes Toward Alcohol Interventions
This paper presents an experimental design examining how direct and indirect parental interventions affect adolescent attitudes toward responsible alcohol consumption. Direct intervention involves explicit dinner-table conversations with teenagers about the dangers of irresponsible drinking; indirect intervention involves modeled adult behavior without verbal instruction. Using both pretest/post-test and post-test control group frameworks, the study measures shifts in expressed beliefs through embedded questionnaires. Two hypotheses guide the design: first, that any intervention will strengthen responsible drinking attitudes; second, that indirect intervention will produce stronger attitudinal change than direct intervention. The paper also addresses sampling, ethical considerations, manipulation checks, and threats to internal and external validity.

What makes this paper effective
- The design clearly distinguishes between direct (explicit verbal) and indirect (modeled behavior) interventions, giving the study a well-defined comparative structure.
- Embedding the alcohol-attitude questions within unrelated question sets is a thoughtful methodological detail that reduces demand characteristics and priming effects.
- The paper addresses both ethical considerations and validity threats, showing awareness of research design limitations beyond just the core hypotheses.
Key academic technique demonstrated
The paper demonstrates hypothesis-driven experimental framing: each hypothesis is tied explicitly to labeled independent and dependent variables. This operational clarity — naming what is manipulated and what is measured — is a foundational technique in behavioral and social science research design that students can apply directly to their own study proposals.
Structure breakdown
The paper moves logically from problem background, to framework (two experimental designs), to hypotheses and variable definitions, to controls and manipulation checks, and finally to sampling ethics and validity. This mirrors the standard sections of an APA-style methods section, making it a useful model for undergraduate research proposals. Each section is concise and focused on a single methodological concern.
Background of the Experiment
The subject matter of this experiment is the effect of direct and indirect intervention on the expressed attitudes of adolescents about responsible and irresponsible alcohol consumption. To test the effect of direct intervention, teenagers will be exposed to explicit conversational messages from parents about the dangers of irresponsible drinking and about strategies for consuming alcohol responsibly. To test the effect of indirect intervention, teenagers will be exposed to implicit messages in the form of modeled adult behaviors, without any explicit verbal instruction directed at them.
In the pretest/post-test version of the experiment, responses will be compared before and after exposure to the intervention. In the post-test version, responses of the test group following exposure to the intervention will be compared to those of a control group not exposed to the intervention.
