Personality Theories and Trait Perspectives (7A) Practice Test

A clinic piloted a brief intervention for insomnia that required patients to follow a fixed bedtime, avoid naps, and complete daily sleep logs for 14 days. Prior to treatment, patients completed a Five Factor Model assessment. The intervention’s success depended on consistent adherence to structured tasks rather than insight-oriented discussion. Which trait would most likely predict better adherence to the protocol?

In a preregistered study on medication adherence, adult participants completed a Five Factor Model inventory at baseline and were then offered an optional 8-week text-message system that: (i) prompts weekly pillbox refills, (ii) requests brief check-ins after missed doses, and (iii) allows participants to set recurring reminders. Enrollment in the system required completing a multi-step setup and committing to weekly confirmations. Over 8 weeks, investigators observed that some participants consistently used the system, maintained stable routines, and proactively adjusted reminders after schedule disruptions. Based on the Five Factor Model, which behavior is most indicative of high conscientiousness in this context?
