Syllabus: Why Are Suicidal Thoughts and Actions Difficult to Explain and Predict?
Compare the theories’ proposed pathways and the time scales on which they should operate.
Why you’re reading it. Turn the ideation-to-action distinction into competing, testable explanations.
A question to consider. Choose two accounts and describe a finding that would favor one over the other without merely renaming the observed outcome.
Why this reading
This compact comparison makes the explanation of suicidal thinking distinct from the explanation of action. Several theories share that distinction while disagreeing about important processes and their timing.
Before you read
Ideation means thoughts about suicide. A moderator changes a relationship; a mediator is a proposed intervening process. Neither a statistical interaction nor an indirect association alone establishes a causal mechanism.
Read for
- Identify one shared premise and one disagreement among the theories.
- Ask whether the evidence concerns concurrent differences, retrospective histories or changes observed prospectively.
Consider afterwards
- Formulate a prediction on which two accounts could disagree. What measurements and time scale would make the comparison informative?
Editorial context
The review reflects evidence available around 2017–2018 and includes authors associated with theories under discussion. Its judgments are arguments to evaluate. Group differences and measures used as proxies for a theoretical construct do not by themselves establish a sequence of causes.
