Objective:
This online study examined the effects of a single imaginal exposure-writing assignment on posttraumatic stress (PTS) and comorbid depressive symptoms.
Method:
Forty-six participants with PTS were allocated to either a single imaginal exposure-writing assignment, a nontrauma writing assignment, or to a nonwriting control condition, and were reassessed 2 and 5 weeks after baseline. Of the 49 participants, 36 were female, with an average age of 23. Participation was conducted through Qualtrics. Effects were assessed with the Posttraumatic Diagnostic Scale (PDS) and the Beck Depression Inventory-II (BDI-II).
Results:
PTS and depressive symptoms decreased over time regardless of the study condition.
Conclusions:
We found no support for the efficacy of a single imaginal exposure-writing assignment in reducing PTS or comorbid depressive symptoms. Suggestions are given for future studies that attempt to identify a minimal dose of imaginal exposure writing for PTS.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
